THE COMPANY

Overview

Context Therapeutics® is a clinical-stage biopharmaceutical company dedicated to improving the lives of women living with cancer.

Profound advancements in oncology drug development have expanded the treatment options available to women with cancer, yet therapeutic resistance and relapse continue to limit the efficacy and duration of such treatments. Collectively, our founders and management team have decades of experience identifying and characterizing the mechanisms that drive cancer initiation and subsequent relapse in women with cancer and have been associated with the development of products such as Kisqali (ribociclib), Arimidex (anastrozole) and Afinitor (everolimus) to treat such cancers.

Our development team is advancing a pipeline of innovative therapies with a primary focus on treating female cancers, which include, but are not limited to, breast, ovarian and endometrial cancer. Our first program and lead product candidate, onapristone extended release (“ONA-XR”), builds upon a foundation of successful drug development by our management team and advisors in the field of female hormone-dependent cancers. ONA-XR is a selective and potentially potent antagonist of the progesterone receptor (“PR”), a receptor that is activated by the hormone progesterone and that has been linked to resistance to multiple classes of cancer therapeutics, including anti-estrogen therapies, that are prescribed to treat female hormone-dependent cancers. In 2020, we initiated a Phase 2 trial of ONA-XR in combination with Arimidex (anastrozole) in PR+ endometrial cancer and preliminary data is expected in the second half of 2022. Also, in 2020 we initiated a Phase 0 trial of ONA-XR in a window of opportunity study in primary breast cancer, and we reported preliminary data at the San Antonio Breast Cancer Symposium in December 2021. The window of opportunity study is a three week study in women with primary breast cancer and subsequent lumpectomy to evaluate the direct effects of ONA-XR on the cancer signaling pathways and the tumor microenvironment. In 2021, a Phase 1b/2 investigator-sponsored trial was initiated in collaboration with Memorial Sloan Kettering Cancer Center to evaluate ONA-XR in combination with Ibrance (palbociclib) and Femara (leterozole) in first line metastatic breast cancer patients with biochemically recurrent disease, defined as circulating tumor DNA (ctDNA) positive. This is potentially a new clinical opportunity for the estimated 20% of first line (“1L”) patients who are at high risk of early disease progression on Ibrance and Femara therapy. In 2021, we completed the first stage of our Phase 2 trial evaluating ONA-XR in recurrent granulosa cell tumors (GCT) of the ovary and in July 2021 we initiated the second stage of this trial evaluating ONA-XR in combination with the antiestrogen, anastrozole. Also in 2021, a Phase 2 investigator-sponsored trial was initiated in collaboration with Wisconsin Oncology Network to evaluate ONA-XR in combination with Faslodex (fulvestrant) in women with second line (“2L”) or third line (“3L”) metastatic breast cancer. In 2021, we also initiated a sub-study of our Phase 2 trial in 2L/3L metastatic breast cancer, which evaluates the uptake of radiolabeled progesterone (F-FFNP) via PET imaging in breast tumors, with preliminary data expected to come in the second half of 2022. Our second program, CLDN6xCD3 bsAb, is an anti-CD3 x anti-Claudin 6 antigen bispecific monoclonal antibody (bsAbs) that is intended to redirect T-cell-mediated lysis toward malignant cells expressing CLDN6. Claudin 6 (CLDN6) is a tight junction membrane protein target expressed in multiple cancers, including ovarian and

endometrial tumors, that is absent from healthy adult tissues. We expect to enter IND-enabling studies for the CLDN6xCD3 bsAb in 2022. Beyond these two product candidates, we have a discovery-stage program evaluating antagonists of Sigma1 for breast and prostate cancer. We believe our team and capabilities uniquely position us to be a leader in developing novel therapies to address female hormone-dependent cancers.

Context retains worldwide development and commercialization rights for ONA-XR outside of Greater China and retains full worldwide development and commercialization rights to certain CLDN6 antibody patents in the field of bispecific antibodies and to certain patents related to Sigma1. Our product candidates are shown in the table below:

Our Strategy

Our goal is to develop and commercialize innovative and differentiated oncology products that address significant unmet medical needs in the field of female cancers. The key components of our strategy to achieve this goal include:

•leveraging the insights, experience and networks of our management team and advisors;

•focusing on drugs and programs that have the opportunity to be first or second in market based on current competition;

•completing clinical development and obtaining regulatory approval for ONA-XR for the treatment of breast, ovarian and endometrial cancer;

•advancing our second program, CLDN6xCD3 bsAb, as rapidly as reasonably possible through preclinical and clinical development;

•developing our other drug candidates;

•evaluating opportunities to accelerate development timelines and enhance the commercial potential of our programs in collaboration with third parties, which may entail the potential out-licensing of our product candidates, including our lead product candidate ONA-XR; and

•in-licensing or acquiring additional drug candidates to build a fully integrated company focused on female hormone-dependent cancers.

Our Focus on Female Hormone-Dependent Cancers

Up to 70% of women with breast, ovarian and endometrial cancer have hormone-dependent cancer. The hormones estrogen and progesterone drive cancer progression in these patients, but anti-estrogens are the only antihormonal therapy that is FDA approved and available to clinicians. Treatment of these patients to date, therefore, has consisted of anti-estrogens alone or in combination with drugs that enhance the antitumor activity of anti-estrogens, including inhibitors of CDK4/6 or PI3Kα. Given the broad use of anti-estrogens, anti-estrogen resistance is now a major clinical challenge. Treatment options for anti-estrogen resistance are limited, provide modest therapeutic benefit and are associated with side effects.

Estrogen and progesterone are master regulators of normal female sex organ development and function, acting via estrogen receptors (“ER”) and progesterone receptors (“PR”). In hormone-dependent cancers, ER and PR are often hyperactive, constantly pushing breast, ovary, and endometrial tissues to grow, divide and metastasize. To block this hormone-mediated growth, patients are administered anti-estrogen therapy (fulvestrant, letrozole, anastrozole or tamoxifen) to block ER signaling and may be used in combination with inhibitors of CDK4/6 or PI3Kα. The cancer cells respond to this selective pressure of ER inhibition, however, by further activating progesterone signaling as a compensatory mechanism, along with other resistance mechanisms that can induce PR signaling, including ER ligand binding mutations (ESR1), growth factor signaling and enrichment of cancer stem cells. Over time, all patients become resistant to anti-estrogens due to direct or indirect compensatory signaling mediated by the PR and other factors. Therefore, PR and proteins that regulate PR represent ideal drug targets to address anti-estrogen resistance.

Overview of Anti-estrogen Resistance Mechanisms

We are building a portfolio of novel agents targeting multiple resistance mechanisms by leveraging our specialized expertise in hormone-dependent cancers.

Our Product Pipeline and Development

PR antagonist program: ONA-XR

Currently, there are no approved therapies that selectively target progesterone receptor positive (PR+) cancers. We have chosen PR antagonism in breast cancer as our initial therapeutic focus due to the well-documented biology of PR signaling as a mechanism of resistance to anti-estrogen therapy in patients with hormone-dependent breast cancer. Hormone-dependent breast cancer cells express estrogen (ER) and/or progesterone receptors (PR) that allow the cells to grow in the presence of the hormones estrogen and/or progesterone. Published data suggests that PR signaling is predominantly required for breast cancer cell renewal (i.e., stemness) and metastatic spread, whereas ER is predominantly required for breast cancer cell proliferation. By combining anti-progestin and anti-estrogen therapy, we have shown preclinically that breast cancer cell growth, renewal, and spread can be mitigated. Based on these data, we believe that ONA-XR, in combination with current standard-of-care anti-estrogens, has the potential to significantly improve clinical outcomes.

ONA-XR is currently being evaluated in three Phase 2 trials, one Phase 1b/2 trial and one Phase 0 biomarker pharmacodynamic trial in women with primary or metastatic breast, ovarian and endometrial cancers. These trials are intended to establish safety, pharmacokinetics, pharmacodynamics, and anti-tumor activity at the recommended Phase 2 dose of ONA-XR to guide potential advancement in Phase 3 development in 2023.

To help inform which patients may be most suitable for treatment with ONA-XR, we are evaluating multiple biomarker assays, including tools to monitor activated progesterone receptor as well as a PR gene activation signature that measures PR signaling activity, both of which are being utilized in our ongoing clinical trials and may be used for patient selection in future clinical trials. We expect to report preliminary data from at least one Phase 2 trial in the first half of 2022 and from the other trials in the second half of 2022.

CLDN6xCD3 bispecific antibody program

Our second program, CLDN6xCD3 bsAb, is an anti-CD3 x anti-Claudin 6 (CLDN6xCD3) antigen bispecific monoclonal antibody (bsAbs) that is intended to redirect T-cell-mediated lysis toward malignant cells expressing CLDN6. Claudin 6 (CLDN6) is a tight junction membrane protein target expressed in multiple hormone-dependent cancers, including ovarian and endometrial tumors, and absent from healthy adult tissues. The structural complexity of Claudin 6 and its similarity to proteins expressed on healthy tissue, particularly Claudin 4 and Claudin 9, have limited its exploitation for targeted oncology therapies. Several global pharmaceutical companies are developing anti-CLDN6 antibodies, but due to significant antibody selectivity challenges, to our knowledge, there are no selective inhibitors of CLDN6 in clinical development. We expect to enter IND-enabling studies for our CLDN6xCD3 bsAb in 2022.

Other preclinical programs

In addition to our product candidates, we are leveraging our knowledge in hormone-dependent cancers to pursue discovery stage research programs, including Sigma1. Sigma1 is a cellular protein that regulates homeostasis and has been shown to play a role in breast and prostate cancer. The Sigma1 discovery research program is currently in lead optimization and has undergone in vivo studies.

Our Management Team

We have assembled an outstanding management team to develop novel products to treat female, hormone-dependent cancers. Members of our management team have experience leading organizations that have advanced multiple oncology therapeutics from early-stage research to clinical trials, and ultimately to regulatory approval and commercialization. Our team’s select accomplishments include:

•Our Chief Executive Officer co-founded Context in 2015 and was previously a venture capitalist at Osage University Partners, where he led multiple oncology investments for the firm that resulted in successful public offerings or acquisitions.

•Our Chief Financial Officer previously served as Chief Financial Officer of Millendo Therapeutics, a publicly-traded biopharmaceutical company. Prior to Millendo, she served as Director of Technical Accounting at PAREXEL International and began her career as an auditor at Ernst & Young.

The consolidated financial statements included elsewhere in this prospectus are those of Context Therapeutics Inc. (formerly Context Therapeutics LLC) and its subsidiaries.

December 2021 Private Placement

On December 1, 2021, we entered into a securities purchase agreement for a private placement (the “Private Placement”) with a select group of accredited investors, which we collectively refer to as the Purchasers. Pursuant to the securities purchase agreement, the Purchasers purchased 5,000,000 shares of our common stock, par value $0.001 per share, together with warrants to purchase 5,000,000 shares of common stock. The purchase price for each share of common stock and accompanying warrant was $6.25 per unit, for an aggregate purchase price of $31,250,000. The warrants have a term of 5.5 years and an exercise price of $6.25 per share. The closing of the purchase and sale of the securities occurred on December 6, 2021.

We also entered into a registration rights agreement with the Purchasers requiring us to register the resale of the shares. We were required to prepare and file a registration statement with the SEC no later than 10 days following the date of the Private Placement. In connection with the Private Placement, we terminated that certain Investors’ Rights Agreement that we entered into in connection with the Series A Financing.

Risks Related to Our Business

Our ability to execute on our business strategy is subject to a number of risks, which are discussed more fully in the section titled “Risk Factors.” You should carefully consider these risks before making an investment in our common stock. These risks include, among others, the following:

•We have never been profitable and may never achieve or maintain profitability.

•We have a limited operating history, have not initiated or completed any large-scale or pivotal clinical trials and have no products approved for commercial sale.

•We rely on a central team consisting of a limited number of employees who provide various administrative, research and development, and other services across our organization, which presents operational challenges that may adversely affect our business.

•We have incurred significant net losses since our inception, and we expect to continue to incur significant net losses for the foreseeable future.

•Our ability to generate revenue and achieve profitability depends significantly on our ability to achieve several objectives relating to the discovery, development and commercialization of our product candidates.

•We will require substantial additional capital to finance our operations. If we are unable to raise substantial additional capital on acceptable terms, or at all, we may be forced to delay, reduce or eliminate some or all of our research programs, product development activities and commercialization efforts or we might have to obtain funds through arrangements, such as out-licensing our product candidates, with collaborative partners or others that may require us to relinquish rights to our technologies or product candidates that we would otherwise not relinquish.

•We are substantially dependent on the success of our first program and lead product candidate, ONA-XR, which is currently in early stage clinical trials. If we are unable to complete development of, obtain approval for and commercialize ONA-XR for one or more indications in a timely manner, our business, financial condition, results of operations and prospects would be materially and adversely affected.

•Our prospects depend in part upon discovering, developing and commercializing additional product candidates.

•Our innovative therapy approach is based on novel ideas and technologies that are unproven and may not result in marketable products, which exposes us to unforeseen risks and makes it difficult for us to predict the time and cost of product development and potential for regulatory approval.

•The regulatory approval processes of the FDA, European Medicines Agency (the “EMA”) and other comparable foreign regulatory authorities are lengthy, time consuming and inherently unpredictable.

•The clinical trials of our product candidates may not demonstrate safety and efficacy to the satisfaction of the FDA, EMA or other comparable foreign regulatory authorities or otherwise produce positive results.

•We rely on third parties to conduct some or all aspects of our product manufacturing, research and preclinical and clinical development, and these third parties may not perform satisfactorily, which may substantially harm our business.

•Our success depends on our ability to protect our intellectual property as well as to operate without infringing the intellectual property rights of third parties.

•We face significant competition and if our competitors develop and market technologies or products more rapidly than we do or that are more effective, safer or less expensive than the product candidates we develop, our commercial opportunities will be impacted.

•Coverage and reimbursement may be limited or unavailable in certain market segments for our product candidates, which could make it difficult for us to sell our product candidates, if approved, profitably.

•The advancement of healthcare reform may negatively impact our ability to sell our product candidates, if approved, profitably.

Our Corporate History

On April 23, 2021, we completed a reverse triangular merger, resulting in Context Therapeutics Inc. becoming the sole holder of 100% of the membership interests in Context Therapeutics LLC, and which resulted in all of the common units, preferred units and all options, warrants or other rights to purchase common or preferred units of Context Therapeutics LLC converting into common stock, preferred stock and all options, warrants or other rights to purchase common or preferred stock of Context Therapeutics Inc. We were previously organized as a limited liability company in Delaware in April 2015 under the name “Context Therapeutics LLC.” Our principal executive offices are located at 3675 Market Street, Suite 200, Philadelphia, Pennsylvania 19104. Our telephone number is (267) 225-7416. Our website address is www.contexttherapeutics.com. Information contained on the website is not incorporated by reference into this prospectus and should not be considered to be part of this prospectus.

We have three wholly-owned subsidiaries: Context Therapeutics LLC, which was formed in the State of Delaware in April of 2015, Context Therapeutics Ireland Limited, which was incorporated under the Companies Act 2014 in Ireland in April 2018, and Context Biopharma, Inc., which was incorporated in the State of Delaware in December 2017.

Implications of Being an Emerging Growth Company

We qualify as an “emerging growth company” under the Jumpstart Our Business Act of 2012, as amended, or the JOBS Act. As a result, we will be permitted to, and intend to, rely on exemptions from certain disclosure requirements. For so long as we are an emerging growth company, we will not be required to:

•have an auditor report on our internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act;

•comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (i.e., certain audit matters);

•submit certain executive compensation matters to stockholder advisory votes, such as “say-on-pay” and “say-on-frequency”; and

•disclose certain executive compensation related items such as the correlation between executive compensation and performance and comparisons of the chief executive officer’s compensation to median employee compensation.

In addition, Section 107 of the JOBS Act also provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended (the “Securities Act”), for complying with new or revised accounting standards. In other words, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to take advantage of the benefits of this extended transition period. Our financial statements may therefore not be comparable to those of companies that comply with such new or revised accounting standards.

We will remain an emerging growth company until the earliest of October 19, 2026 or (i) the last day of the first fiscal year in which our total annual gross revenues exceed $1.07 billion, (ii) the date that we become a “large accelerated filer” as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which would occur if the market value of our common stock that is held by non-affiliates exceeds $700 million as of the last business day of our most recently completed second fiscal quarter, or (iii) the date on which we have issued more than $1 billion in non-convertible debt during the preceding three-year period.

We have never been profitable and may never achieve or maintain profitability.

We have not commercialized any products and have yet to generate any revenue from product sales. The amount of our future net losses will depend, in part, on our expenses and our ability to generate revenues. Our current and future product candidates will require substantial additional development time and resources before we may realize revenue from product sales, if at all. We expect to continue to incur significant expenses and operating losses for the foreseeable future. We anticipate that our expenses will increase substantially if and as we:

•continue our current research and development programs, including conducting laboratory, preclinical and clinical studies for product candidates;

•initiate clinical trials for product candidates;

•seek to identify, assess, acquire or develop additional research programs or product candidates;

•maintain, expand and protect our intellectual property portfolio;

•seek marketing approvals for any product candidates that may successfully complete development;

•establish a sales, marketing and distribution infrastructure to commercialize any products that may obtain marketing approval;

•further develop and refine the manufacturing process for our product candidates;

•change or add additional manufacturers or suppliers of pharmaceutical or biological materials or product candidates;

•further develop our anti-hormonal resistance therapies;

•acquire or in-license other technologies;

•seek to attract and retain new and existing personnel; and

•expand our facilities.

Our first program and lead product candidate, ONA-XR, is currently in Phase 2 clinical trials. No clinical studies have begun on our second program, CLDN6xCD3 bsAb, and our Sigma1 discovery research program is currently in lead optimization and has undergone in vivo studies. It will be several years, if ever, before we obtain regulatory approval for a therapeutic product candidate, at which time any revenues for such product candidate will depend upon many factors, including, market conditions, costs and effectiveness of manufacturing, sales, marketing and distribution operations related to such product candidate, and the terms of any collaboration or other strategic arrangement we may have with respect to such product candidate and levels of reimbursement from third-party payors.

If we are unable to develop and commercialize one or more product candidates either alone or with collaborators, including through the potential out-licensing of our product candidates, or if revenues from any product candidate that receives marketing approval or is commercialized are insufficient, we may not achieve profitability or sustain profitability, which would have an adverse effect on the value of our common stock which would be materially adversely affected.

If we are unable to raise substantial additional capital on acceptable terms, or at all, we may be forced to delay, reduce or eliminate some or all of our research programs, product development activities and commercialization efforts.

The process of identifying product candidates and conducting preclinical and clinical trials is time consuming, expensive, uncertain and takes years to complete. Our operations have consumed substantial amounts of cash since inception. We expect our expenses to increase in connection with our ongoing activities, particularly as we identify, continue the research and development of, initiate clinical trials of, and seek marketing approval for, product candidates. In addition, if any therapeutic product candidate that we develop alone or with collaborators obtains marketing approval, we may incur significant commercialization expenses related to product manufacturing, sales, marketing and distribution efforts. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise sufficient capital when needed, we may be forced to delay, reduce or eliminate current or future research programs, product development activities and/or commercialization efforts.

Adequate additional financing may not be available to us on acceptable terms, or at all. If we are unable to obtain sufficient funding on a timely basis or on favorable terms, we may be required to significantly delay, reduce or eliminate one or more of our research or product development programs and/or commercialization efforts or we might have to obtain funds through arrangements, such as out-licensing our product candidates, with collaborative partners or others that may require us to relinquish rights to our technologies or product candidates that we otherwise would not relinquish. We may also be unable to expand our operations or otherwise capitalize on business opportunities as desired. Any of these events could materially adversely affect our financial condition and business prospects.

We have a limited operating history, which makes it difficult to evaluate our current business and future prospects and may increase the risk of your investment.

We are a clinical-stage biopharmaceutical company with a limited operating history. We were founded in 2015 and spent the first three years of our company’s history developing and refining our therapeutic approach, and only since then have we focused our efforts on advancing the development of product candidates.

Investment in biopharmaceutical product development is a highly speculative endeavor and entails substantial upfront capital expenditures. There is significant risk that any product candidate will fail to demonstrate adequate efficacy or an acceptable safety profile, obtain any required regulatory approvals or become commercially viable. Our product candidates and the therapeutic approach we are using are new and unproven. We have commenced Phase 2 human clinical trials for one of our product candidates, but have not demonstrated an ability to initiate clinical trials for our other product candidates or successfully complete any clinical trials, obtain any required marketing approvals, manufacture products, conduct sales, marketing and distribution activities, or arrange for a third party to do any of the foregoing on our behalf.

Consequently, any predictions made about our future success or viability may not be as accurate as they could be if we had a history of successfully developing and commercializing products. Our limited operating history, particularly in light of the rapidly evolving nature of the biopharmaceutical industries and the hormone-dependent cancer therapeutics field, may make it difficult to evaluate our technology and business prospects or to predict our future performance.

We may expend our limited resources pursuing particular research programs or product candidates that may be less successful or profitable than other programs or product candidates.

Research programs to identify new product candidates require substantial technical, financial, and human resources. We may focus our efforts and resources on potential programs or product candidates that ultimately prove to be unsuccessful. The successful completion of a clinical trial with regard to any of our product candidates is not assured despite the expenditure of significant resources in pursuit of their development, and our spending on current and future research and development programs and product candidates may not yield any commercially viable products.

Additionally, if we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing or other strategic arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate.

Our business may be adversely affected by the ongoing coronavirus pandemic.

The outbreak of the novel Coronavirus (“COVID-19”) has evolved into a global pandemic. The extent to which the COVID-19 pandemic impacts our business and operating results will depend on future developments that are highly uncertain and cannot be accurately predicted, including new information that may emerge concerning COVID-19 and the actions to contain the virus or treat its impact, among others.

Should COVID-19 continue to spread, our business operations could be delayed or interrupted. For instance, our research and development may be affected by the pandemic. Site initiation, participant recruitment and enrollment, participant dosing, distribution of clinical trial materials, study monitoring and data analysis may be paused or delayed due to changes in hospital or university policies, federal, state or local regulations, prioritization of hospital resources toward pandemic efforts, or other reasons related to the pandemic. If COVID-19 continues to spread, some participants and clinical investigators may not be able to comply with clinical trial protocols. For example, quarantines or other travel limitations (whether voluntary or required) may impede participant movement, affect sponsor access to study sites, or interrupt healthcare services, and we may be unable to conduct our research activities, including clinical trials.

Infections and deaths related to the pandemic have disrupted and may continue to disrupt the United States’ healthcare and healthcare regulatory systems. Such disruptions could divert healthcare resources away from, or materially delay FDA review and/or approval. It is unknown how long these disruptions could continue, were they to occur. Any elongation or de-prioritization of clinical trials or delay in regulatory review resulting from such disruptions could materially affect the development and study of our product candidates.

In the event of a shelter-in-place order or other mandated local travel restrictions, our employees and consultants conducting research and development or manufacturing activities may not be able to access their laboratory or manufacturing space, and our core activities may be significantly limited or curtailed, possibly for an extended period of time.

The spread of COVID-19, which has caused a broad impact globally, including restrictions on travel and quarantine policies put into place by businesses and governments, may have a material economic effect on our business. New or renewed restrictions may be implemented in response to evolving conditions, new variants of the virus (including the Omicron variant) and overall uncertainty about the timing of widespread availability of vaccines. While the potential economic impact brought by and the duration of the pandemic may be difficult to assess or predict, it has already caused, and is likely to result in further, significant disruption of global financial markets, which may reduce our ability to access capital either at all or on favorable terms. In addition, a recession, depression or other sustained adverse market event resulting from the spread of COVID-19 could materially and adversely affect our business and the value of our common stock.

The ultimate impact of the current pandemic, or any other health epidemic, is highly uncertain and subject to change. We do not yet know the full extent of potential delays or impacts on our business, our clinical trials, our

research programs, healthcare systems or the global economy as a whole. However, these effects could have a material impact on our operations, and we will continue to monitor the situation closely.

Our governing documents designate the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of state law actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.

Our amended & restated certificate of incorporation provides that, unless we consent in writing to the selection of an alternative form, the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, the United States District Court for the District of Delaware) will be the sole and exclusive forum for: (1) any derivative action or proceeding brought on our behalf; (2) any action asserting a claim of breach of a fiduciary duty or other wrongdoing by any of our directors, officers, employees or agents to us or our stockholders; (3) any action asserting a claim against us arising pursuant to any provision of the General Corporation Law of the State of Delaware or our amended & restated certificate of incorporation or amended & restated bylaws; (4) any action to interpret, apply, enforce or determine the validity of our amended & restated certificate of incorporation or amended & restated bylaws; or (5) any action asserting a claim governed by the internal affairs doctrine. In addition, our amended & restated certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States of America shall, to the fullest extent permitted by law, be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. Notwithstanding the foregoing, the exclusive forum provision shall not apply to claims seeking to enforce any liability or duty created by the Exchange Act.

This choice of forum provision may limit our stockholders’ ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuits against us and our directors, officers, employees and agents even though an action, if successful, might benefit our stockholders. Stockholders who do bring a claim in the Court of Chancery could face additional litigation costs in pursuing any such claim, particularly if they do not reside in or near Delaware. The Court of Chancery may also reach different judgments or results than would other courts, including courts where a stockholder considering an action may be located or would otherwise choose to bring the action, and such judgments or results may be more favorable to us than to our stockholders. Alternatively, if a court were to find this provision inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could have a material adverse effect on our business, financial condition or results of operations.

Risks Related to our Product Candidates

Our business is dependent on the successful development, regulatory approval and commercialization of our therapeutic product candidates, ONA-XR and CLDN6xCD3 bsAb, which are in the early stages of development.

We have no products approved for sale. The success of our business, including our ability to finance our company and generate any revenue in the future, will primarily depend on the successful development, regulatory approval and commercialization of ONA-XR and CLDN6xCD3 bsAb, as well as other product candidates derived from our anti-hormone resistant therapy approach, which may never occur.

In the future, we may also become dependent on other product candidates that we may develop or acquire; however, not all of our product candidates have been tested in humans and given our early stage of development, it may be many years, if at all, before we have demonstrated the safety and efficacy of a hormone-dependent cancer treatment sufficient to warrant approval for commercialization.

We have not previously submitted a new drug application (“NDA”) or biologics license application (“BLA”), to the FDA or similar regulatory approval filings to comparable foreign authorities, for any product candidate, and we cannot be certain that our product candidates will be successful in clinical trials or receive regulatory approval. Further, any future product candidates may not receive regulatory approval even if they are successful in clinical trials. If we do not receive regulatory approvals for our product candidates, we may not be able to continue our operations. Even if we successfully obtain regulatory approvals to market a product candidate, our revenue will be

dependent, in part, upon the size of the markets in the territories for which we gain regulatory approval and have commercial rights. If the markets or patient subsets that we are targeting are not as significant as we estimate, we may not generate significant revenues from sales of such products, if approved.

We plan to seek regulatory approval to commercialize our product candidates both in the United States and in selected foreign countries. While the scope of regulatory approval generally is similar in other countries, in order to obtain separate regulatory approval in other countries we must comply with numerous and varying regulatory requirements of such countries regarding safety and efficacy. Other countries also have their own regulations governing, among other things, clinical trials and commercial sales, as well as pricing and distribution of our product candidates, and we may be required to expend significant resources to obtain regulatory approval and to comply with ongoing regulations in these jurisdictions.

The clinical and commercial success of our current and any future product candidates will depend on a number of factors, including the following:

•our ability to raise any additional required capital on acceptable terms, or at all;

•our ability to complete IND-enabling studies and successfully submit an IND;

•timely completion of our preclinical studies and clinical trials, which may be slower or cost more than we currently anticipate and will depend substantially upon the performance of third-party contractors;

•whether we are required by the FDA or similar foreign regulatory agencies to conduct additional clinical trials or other studies beyond those planned to support approval of our product candidates;

•acceptance of our proposed indications and primary endpoint assessments relating to the proposed indications of our product candidates by the FDA and similar foreign regulatory authorities;

•our ability to consistently provide for manufacturing of our product candidates on a timely basis;

•our ability, and the ability of any third parties with whom we contract, to remain in good standing with regulatory agencies and develop, validate and maintain commercially viable manufacturing processes that are compliant with current good manufacturing practices (“cGMPs”);

•our ability to demonstrate to the satisfaction of the FDA and similar foreign regulatory authorities the safety, efficacy and acceptable risk-benefit profile of our product candidates;

•the prevalence, duration and severity of potential side effects or other safety issues experienced with our product candidates or future approved products, if any;

•the timely receipt of necessary marketing approvals from the FDA and similar foreign regulatory authorities;

•achieving and maintaining, and, where applicable, ensuring that our third-party contractors achieve and maintain, compliance with our contractual obligations and with all regulatory requirements applicable to our lead product candidates or any future product candidates or approved products, if any;

•the willingness of physicians, operators of hospitals and clinics and patients to utilize or adopt our anti-hormone resistant therapy approach;

•our ability to successfully develop a commercial strategy and thereafter commercialize our current product candidates or any future product candidates in the United States and internationally, if approved for marketing, sale and distribution in such countries and territories, whether alone or in collaboration with others, including through the potential out-licensing of our product candidates;

•the availability of coverage and adequate reimbursement from managed care plans, private insurers, government payors (such as Medicare and Medicaid) and other third-party payors for any of our product candidates that may be approved;

•the convenience of our treatment or dosing regimen;

•acceptance by physicians, payors and patients of the benefits, safety and efficacy of our product candidates or any future product candidates, if approved, including relative to alternative and competing treatments;

•patient demand for our current or future product candidates, if approved;

•our ability to establish and enforce intellectual property rights in and to our product candidates; and

•our ability to avoid third-party patent interference, intellectual property challenges or intellectual property infringement claims.

These factors, many of which are beyond our control, could cause us to experience significant delays or an inability to obtain regulatory approvals or commercialize our current or future product candidates. Even if regulatory approvals are obtained, we may never be able to successfully commercialize any product candidates. Accordingly, we cannot provide assurances that we will be able to generate sufficient revenue through the sale of our product candidate or any future product candidates to continue our business or achieve profitability.

Our innovative therapy approach is based on novel ideas and technologies that are unproven and may not result in marketable products, which exposes us to unforeseen risks and makes it difficult for us to predict the time and cost of product development and potential for regulatory approval.

Our foundational science and product development approach are based on the selective targeting of hormone-dependent cancers, including by inhibiting progesterone receptor binding to chromatin, and by inhibiting CLDN6, in each case to elicit meaningful anticancer activity. We believe that this approach may offer an improved therapeutic effect by downregulating PR effector functions associated with anti-estrogen resistant and inhibit tumor growth, as well as redirect T-cell-mediated lysis toward malignant cells expressing CLDN6. However, this approach to treating cancer is novel and the scientific research that forms the basis of our efforts to develop therapeutics that effectively target anti-hormone treatment resistance and inhibit membrane protein targets is both preliminary and limited.

As such, we cannot assure you that even if we are able to develop cancer therapeutic candidates capable of addressing anti-estrogen resistance or redirecting T-cell-mediated lysis toward malignant cells, that such therapy would safely and effectively treat cancers. We may spend substantial funds attempting to develop this approach and never succeed in developing a marketable therapeutic.

Furthermore, no regulatory authority has granted approval for a cancer therapy based on a selective targeting of PR+ or Claudin 6 positive cancers. As such, we believe the FDA has limited experience with evaluating our approach, which may increase the complexity, uncertainty and length of the regulatory approval process for our product candidates. We may never receive approval to market and commercialize any product candidate. Even if we obtain regulatory approval, the approval may be for targets, disease indications, lines of therapy or patient populations that are not as broad as we intended or desired or may require labeling that includes significant use or distribution restrictions or safety warnings.

Results of preclinical studies, early clinical trials or analyses may not be indicative of results obtained in later trials.

The results of preclinical studies, early clinical trials or analyses of our product candidates may not be predictive of the results of later-stage clinical trials. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through preclinical studies and initial clinical trials. A number of companies in the biopharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or adverse safety profiles, notwithstanding promising results in earlier trials. In addition, conclusions based on promising data from analyses of clinical results may be shown to be incorrect when implemented in prospective clinical trials. Even if our ongoing clinical trials for ONA-XR and future clinical trials for our other product candidates are completed as planned, we cannot be certain that their results will support the safety and efficacy sufficient to obtain regulatory approval.

Interim “top-line” and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, we may publish interim “top-line” or preliminary data from our clinical studies. Interim data from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available. Preliminary or “top-line” data also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, interim and preliminary data should be viewed with caution until the final data are available. Adverse differences between preliminary or interim data and final data could significantly harm our business prospects.

Our product candidates may cause serious adverse events or undesirable side effects, which may delay or prevent marketing approval, or, if approved, require them to be taken off the market, require them to include safety warnings or otherwise limit their sales.

Serious adverse events or undesirable side effects caused by ONA-XR, CLDN6xCD3 bsAb or any other product candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other comparable foreign authorities. Results of any clinical trial we conduct could reveal a high and unacceptable severity and prevalence of side effects or unexpected characteristics. Patients treated with ONA-XR to date, at high doses have experienced adverse events that include, but are not limited to, fatigue, liver enzyme elevations and nausea.

If unacceptable side effects arise in the development of our product candidates, we, the FDA or the institutional review boards at the institutions in which our studies are conducted, or the data safety monitoring board, if constituted for our clinical trials, could recommend a suspension or termination of our clinical trials, or the FDA or comparable foreign regulatory authorities could order us to cease further development of or deny approval of a product candidate for any or all targeted indications. In addition, drug-related side effects could affect patient recruitment or the ability of enrolled patients to complete a trial or result in potential product liability claims. In addition, these side effects may not be appropriately recognized or managed by the treating medical staff. We expect to have to train medical personnel using our product candidates to understand the side effect profiles for our clinical trials and upon any commercialization of any of our product candidates. Inadequate training in recognizing or managing the potential side effects of our product candidates could result in patient injury or death. Any of these occurrences may harm our business, financial condition and prospects significantly.

Additionally, if one or more of our product candidates receives marketing approval, and we or others later identify undesirable side effects caused by such products, a number of potentially significant negative consequences could result, including:

•regulatory authorities may withdraw approvals of such product;

•regulatory authorities may require additional warnings on the label, such as a “black box” warning or contraindication;

•additional restrictions may be imposed on the marketing of the particular product or the manufacturing processes for the product or any component thereof;

•we may be required to implement a Risk Evaluation and Mitigation Strategy, or REMS, or create a medication guide outlining the risks of such side effects for distribution to patients;

•we could be sued and held liable for harm caused to patients;

•the product may become less competitive; and

•our reputation may suffer.

Any of these events could prevent us from achieving or maintaining market acceptance of a product candidate, if approved, and could significantly harm our business, results of operations and prospects.

The success of our business depends primarily upon our ability to identify, develop and commercialize products using our proprietary technologies.

Besides our ONA-XR product candidate, all of our current product candidates and product development programs are still in the IND validation process. We may be unsuccessful in advancing those product candidates into clinical development or in identifying and developing additional product candidates.

Our ability to identify and develop product candidates is subject to the numerous risks associated with preclinical and early stage biopharmaceutical development activities, including that:

•the use of our Sigma1 discovery research program may be ineffective in identifying additional product candidates;

•we may not be able to assemble sufficient resources to acquire or discover additional product candidates, including through the potential out-licensing of our product candidates;

•we may not be able to enter into collaborative arrangements to facilitate development of product candidates;

•competitors may develop alternatives that render our product candidates obsolete or less attractive;

•our product candidates may be covered by third parties’ patents or other exclusive rights;

•the regulatory pathway for a product candidate may be too complex, expensive or otherwise difficult to navigate successfully; or

•our product candidates may be shown to not be effective, have harmful side effects or otherwise pose risks not outweighed by such product candidate’s benefits or have other characteristics that may make the products impractical to manufacture, unlikely to receive any required marketing approval, unlikely to generate sufficient market demand or otherwise not achieve profitable commercialization.

Even if we do commence additional clinical trials of product candidates and continue to identify new product candidates, such product candidates may never be approved. Failure to successfully identify and develop new product candidates and obtain regulatory approvals for our products would have a material adverse effect on our business and financial condition and could cause us to cease operations.

If our product candidates do not achieve projected development milestones or commercialization in the announced or expected timeframes, the further development or commercialization of such product candidates may be delayed, and our business will be harmed.

We sometimes estimate, or may in the future estimate, the timing of the accomplishment of various scientific, clinical, manufacturing, regulatory and other product development objectives. These milestones may include our expectations regarding the commencement or completion of scientific studies or clinical trials, the submission of regulatory filings, the receipt of marketing approval or the realization of other commercialization objectives.

The achievement of many of these milestones may be outside of our control. All of these milestones are based on a variety of assumptions, including assumptions regarding capital resources, constraints and priorities, progress of and results from development activities and the receipt of key regulatory approvals or actions, any of which may cause the timing of achievement of the milestones to vary considerably from our estimates.

If our collaborators or ourselves fail to achieve announced milestones in the expected timeframes, the commercialization of the product candidates may be delayed, our credibility may be undermined, our business and results of operations may be harmed, and the price of our common stock may decline.

Product liability lawsuits against us could cause us to incur substantial liabilities and could limit commercialization of any products that we develop alone or with collaborators.

We face an inherent risk of product liability and professional indemnity exposure related to the testing in clinical trials of our product candidates. We will face an even greater liability risk if we commercially sell any products that we or our collaborators may develop for human use.

Manufacturing defects, errors in product distribution or storage processes, improper administration or application and known or unknown side effects of product usage may result in liability claims against us or third parties with which we have relationships. These actions could include claims resulting from acts by our collaborators, licensees and subcontractors over which we have little or no control. For example, our liability could be sought by patients participating in clinical trials for potential therapeutic product candidates as a result of unexpected side effects, improper product administration or the deterioration of a patient’s condition, patient injury or even death.

Criminal or civil proceedings might be filed against us by patients, regulatory authorities, biopharmaceutical companies and any other third party using or marketing any product candidates or products that we develop alone or with collaborators. On occasion, large judgments have been awarded in class action lawsuits based on products that had unanticipated adverse effects. If we cannot successfully defend ourselves against claims that product candidates or products we develop alone or with collaborators caused harm, we could incur substantial liabilities.

Clinical development does not always fully characterize the safety and efficacy profile of a new medicine, and it is always possible that a drug or biologic, even after regulatory approval, may exhibit unforeseen side effects. If our product candidates were to cause adverse side effects during clinical trials or after approval, we may be exposed to substantial liabilities.

Product liability insurance coverage may not be adequate to cover all liabilities that we may incur. We anticipate that we will need to increase our insurance coverage when we expand our clinical trials and if our collaborators or ourselves successfully commercialize any products.

Risks Related to Our Organization, Structure and Operations

Our reliance on a central team consisting of a limited number of employees and consultants who provide various administrative, research and development, and other services across our organization presents operational challenges that may adversely affect our business.

As of December 1, 2021, we had five full-time employees. We also have three consultants who we rely on for research and development, business development and other services. While we believe this structure enables us to reduce certain infrastructure costs, the small size of our centralized team may limit our ability to devote adequate personnel, time and resources to support the operations of our business, including our research and development activities, and the management of financial, accounting and reporting matters. If our centralized team fails to provide adequate administrative, research and development, or other services across our entire organization, our business, financial condition and results of operations could be harmed.

Our future success depends on our ability to retain our Chief Executive Officer, Chief Financial Officer, Chief Legal Officer, Chief Medical Officer, and other key executives and to attract, retain and motivate qualified personnel.

We are highly dependent on the research and development experience, technical skills, leadership and continued service of certain members of our management and scientific teams, including Martin Lehr, our Chief Executive Officer, Jennifer Minai-Azary, our Chief Financial Officer, Alex Levit, our Chief Legal Officer, and Tarek Sahmoud, our Chief Medical Officer.

Although we have formal employment agreements and consulting agreements with substantially all of our executive officers, these agreements do not prevent them from terminating their employment with us at any time.

The loss of the services of any of these persons could impede the achievement of our research, development and commercialization objectives.

Recruiting and retaining qualified scientific, clinical, manufacturing and, if we retain commercialization responsibility for any product candidate we develop alone or with collaborators, sales and marketing personnel, will also be critical to our success. We may not be able to attract and retain these personnel on acceptable terms or at all given the competition among numerous pharmaceutical and biotechnology companies for similar personnel. We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and development and commercialization strategies. Our consultants and advisors may be employed by employers other than us and may have commitments under consulting or advisory contracts with other entities that may limit their availability to us.

The inability to recruit, integrate, motivate and retain additional skilled and qualified personnel, or the loss of services of certain executives, key employees, consultants or advisors, may impede the progress of our research, development and commercialization objectives and have a material adverse effect on our business.

We will need to expand our organization, and we may experience difficulties in managing this growth, which could disrupt our operations.

We will need to significantly expand our organization, and our future financial performance, ability to develop and commercialize product candidates alone or with collaborators and ability to compete effectively will depend in part on our ability to effectively manage any future growth. We may have difficulty identifying, hiring and integrating new personnel.

Many of the biopharmaceutical companies that we compete against for qualified personnel and consultants have greater financial and other resources, different risk profiles and a longer history than we do. If we are unable to continue to attract and retain high-quality personnel and consultants, the rate and success at which we can identify and develop product candidates, enter into collaborative arrangements and otherwise operate our business will be limited.

Future growth would impose significant additional responsibilities on our management, including the need to identify, recruit, maintain, motivate and integrate additional employees, consultants and contractors. Management may need to divert a disproportionate amount of its attention away from our day-to-day activities and devote a substantial amount of time to managing these growth activities. Due to our limited financial resources and the limited experience of our management team in managing a company with such anticipated growth, we may not be able to effectively manage the expected expansion of our operations or recruit and train additional qualified personnel.

Moreover, the expected physical expansion of our operations may lead to significant costs and may divert our management and business development resources from other projects, such as the development of product candidates. If we are not able to effectively manage the expansion of our operations, it may result in weaknesses in our infrastructure, increase our expenses more than expected, give rise to operational mistakes, loss of business opportunities, loss of employees, consultants and contractors and reduced productivity.

Our insurance policies are expensive and protect us only from some business risks, which leaves us exposed to significant uninsured liabilities.

We do not carry insurance for all categories of risk that our business may encounter. If we obtain marketing approval for any product candidates that we or our collaborators may develop, we intend to acquire insurance coverage to include the sale of commercial products, but we may be unable to obtain such insurance on commercially reasonable terms or in adequate amounts. We do not carry specific biological or hazardous waste insurance coverage, and our property, casualty and general liability insurance policies specifically exclude coverage for damages and fines arising from biological or hazardous waste exposure or contamination.

Accordingly, in the event of contamination or injury, we could be held liable for damages or be penalized with fines in an amount exceeding our resources, and clinical trials or regulatory approvals for any of our product candidates could be suspended. As a public company it may be more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified individuals to serve on our board of directors, our board committees or as our executive officers.

Insurance coverage is becoming increasingly expensive, and in the future, we may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses. We do not know if we will be able to maintain existing insurance with adequate levels of coverage, and any liability insurance coverage we acquire in the future may not be sufficient to reimburse us for any expenses or losses we may suffer. A successful liability claim or series of claims brought against us could require us to pay substantial amounts and cause our share price to decline and, if judgments exceed our insurance coverage, could adversely affect our results of operations and business, including preventing or limiting the development and commercialization of any product candidates that we or our collaborators may develop.

Risks Related to Our Reliance on Third Parties

We expect to depend on collaborations with third parties for certain research, development and commercialization activities, and if any such collaborations are not successful, it may harm our business and prospects.

Working with collaborators poses several significant risks, including the following:

•limited availability of resource allocation and other developmental decisions made by our collaborators about the product candidates that we seek to develop with them may result in the delay or termination of research programs, studies or trials, repetition of or initiation of new studies or trials or provision of insufficient funding or resources for the completion of studies or trials or the successful marketing and distribution of any product candidates that may receive approval;

•collaborators could independently develop, or develop with third parties, product candidates that compete directly or indirectly with our product candidates if the collaborators believe that competitive products are more likely to be successfully developed or can be commercialized under terms that are more economically attractive than ours;

•collaborators may not properly obtain, maintain, enforce or defend our intellectual property or proprietary rights or may use our proprietary information in such a way that could jeopardize or invalidate our proprietary information or expose us to potential litigation; and

•disputes may arise between us and our collaborators that result in the delay or termination of the research, development or commercialization activities or that result in costly litigation or arbitration that diverts management attention and resources.

Our ability to generate revenues from these arrangements will depend on our collaborators’ abilities to successfully perform the functions assigned to them in these arrangements. If our collaborations, including those in which we may out-license our product candidates, do not result in the successful development and commercialization of product candidates, or if one of our collaborators terminates its agreement with us, we may not receive the expected deliverables or services from our collaborators, nor receive any future funding or milestone or royalty payments under the collaboration.

If we do not receive the funding or expected deliverables or services from our collaborators, we expect under these agreements, our development of product candidates could be delayed, and we may need additional resources to develop such product candidates. In addition, if one of our collaborators terminates its agreement with us, we may find it more difficult to find a suitable replacement collaborator or attract new collaborators and may need to raise additional capital to pursue further development or commercialization of the applicable product candidates.

These events could delay development programs and negatively impact the perception of our company in business and financial communities. Failure to develop or maintain relationships with any current collaborators could result in the loss of opportunity to work with that collaborator or reputational damage that could impact our relationships with other collaborators in the relatively small industry communities in which we operate.

Moreover, all of the risks relating to product development, regulatory approval and commercialization described in this prospectus apply to the activities of our collaborators. If our existing collaboration agreements or any collaborative or strategic relationships we may establish in the future are not effective and successful, it may damage our reputation and business prospects, delay or prevent the development and commercialization of product candidates and inhibit or preclude our ability to realize any revenues.

We have relied on and we expect to continue to rely on third parties to conduct, supervise and monitor our clinical trials and some aspects of our research and preclinical testing, and if those third parties do not successfully carry out their contractual duties, comply with regulatory requirements, or otherwise perform in a satisfactory manner, we may not be able to obtain regulatory approval or commercialize product candidates, or such approval or commercialization may be delayed, and our business may be substantially harmed.

We have relied on and we expect to continue to rely on medical institutions, clinical investigators, contract laboratories and other third parties, such as contract research organizations (“CROs”) to conduct preclinical studies and clinical trials for our product candidates. Nevertheless, we are responsible for ensuring that each of our studies and trials is conducted in accordance with the applicable protocol, legal and regulatory requirements and scientific standards, and our reliance on such third parties will not relieve us of our regulatory responsibilities. For example, we remain responsible for ensuring that each of our clinical trials is conducted in accordance with the general investigational plan and protocols for the trial. Moreover, the FDA requires us to comply with regulations, commonly referred to as good clinical practices, or GCPs, for conducting, monitoring, recording and reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the rights, integrity and confidentiality of trial participants are protected.

Although we have designed and intend to design future trials for our product candidates either alone or with collaborators, third parties may conduct all of the trials. As a result, many important aspects of our research and development programs, including their conduct and timing, will be outside of our direct control. Our reliance on third parties to conduct future studies and trials will also result in less direct control over the management of data developed through studies and trials than would be the case if we were relying entirely upon our own staff. Communicating with outside parties can also be challenging, potentially leading to mistakes and difficulties in coordinating activities. Such third parties may have staffing difficulties, fail to comply with contractual obligations, experience regulatory compliance issues, undergo changes in priorities, become financially distressed or form relationships with other entities, some of which may be our competitors.

We also face the risk of potential unauthorized disclosure or misappropriation of our intellectual property by CROs or other third parties, which may reduce our trade secret protection and allow our potential competitors to access and exploit our proprietary technology. For any violations of laws and regulations during the conduct of our preclinical studies and clinical trials, we could be subject to warning letters or enforcement action that may include civil penalties up to and including criminal prosecution.

If we, our collaborators, our CROs or other third parties fail to comply with applicable GCPs, the clinical data generated in our clinical trials may be deemed unreliable and FDA or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. We also are required to register certain ongoing clinical trials and post the results of such completed clinical trials on a government-sponsored database, within certain timeframes. Failure to do so can result in fines, adverse publicity and civil and criminal sanctions.

If our CROs or other third parties do not successfully carry out their contractual duties or obligations, fail to meet expected deadlines, or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols or regulatory requirements or for any other reasons, trials for product candidates may be extended, delayed or terminated, and we or our collaborators may not be able to obtain regulatory

approval for, or successfully commercialize, any product candidate that we develop. If we are required to repeat, extend the duration of or increase the size of any trials we conduct, it could significantly delay commercialization and require significantly greater expenditures.

As a result of any of these factors, our financial results and the commercial prospects for any product candidate that we or our collaborators may develop would be harmed, our costs could increase and our ability to generate revenues could be delayed.

If we are unable to obtain sufficient quantities of raw materials and supplies, at acceptable prices and on a timely basis, it could harm our business.

We are dependent on third parties for the supply of various pharmaceutical and biological materials and the manufacture of product supplies that are necessary to produce our product candidates. The supply of these materials could be reduced or interrupted at any time. In such case, identifying and engaging an alternative supplier or manufacturer could result in delay, and we may not be able to find other acceptable suppliers or manufacturers on acceptable terms, or at all.

Changing suppliers or manufacturers may involve substantial costs and is likely to result in a delay in our desired clinical and commercial timelines. If we change suppliers or manufacturers for commercial production, applicable regulatory agencies may require us to conduct additional studies or trials. If key suppliers or manufacturers are lost, or if the supply of the materials is diminished or discontinued, we or our collaborators may not be able to develop, manufacture and market product candidates in a timely and competitive manner, or at all. If any of our product candidates receives approval, we will likely need to seek alternative sources of supply of raw materials or manufactured product supplies and there can be no assurance that we will be able to establish such relationships to provide such supplies on commercially reasonable terms or at acceptable quality levels, if at all. If we are unable to identify and procure additional sources of supply that fit our required needs, we could face substantial delays or incur additional costs in procuring such materials.

We may rely on third parties for the manufacturing process of product candidates, and failure by those parties to adequately perform their obligations could harm our business.

We do not currently own any facility that may be used as our clinical-scale manufacturing and processing facility and expect that we will rely on outside vendors for at least a portion of the manufacturing process of product candidates that we or our collaborators may develop. The facilities used by our contract manufacturers to manufacture product candidates must be approved by the FDA or other foreign regulatory agencies pursuant to inspections that will be conducted after we submit an application to the FDA or other foreign regulatory agencies. To the extent that we or our collaborators engage third parties for manufacturing services, we will not control the manufacturing process of, and will be completely dependent on, our contract manufacturing providers for compliance with cGMP requirements for manufacture of the product candidates.

We have not yet caused any product candidates to be manufactured or processed on a commercial scale and may not be able to do so. We will make changes as we work to optimize the manufacturing process, and we cannot be sure that even minor changes in the process will result in products that are safe and effective. If our contract manufacturers cannot successfully manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA or other regulatory authorities, they will not be able to secure and/or maintain regulatory approval for their manufacturing facilities. In addition, we have no control over the ability of our contract manufacturers to maintain adequate quality control, quality assurance and qualified personnel.

If the FDA or a comparable foreign regulatory authority does not approve these facilities for the manufacture of product candidates or if it withdraws any such approval in the future, we may need to find alternative manufacturing facilities, which would significantly impact our ability to develop, obtain regulatory approval for or market any of our or our collaborators’ potential products.

If we are not able to establish collaborations on commercially reasonable terms, we may have to alter our research, development and commercialization plans.

Our research and product development programs and the potential commercialization of our product candidates will require substantial additional cash to fund expenses, and we expect that we will continue to seek collaborative arrangements, including the potential out-licensing of our product candidates, for the development and potential commercialization of current and future product candidates or the development of ancillary technologies.

We face significant competition in establishing relationships with appropriate collaborators. In addition, there have been a significant number of recent business combinations among large pharmaceutical companies that have resulted in a reduced number of potential future collaborators. Whether we reach a definitive agreement for a collaboration will depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator’s evaluation of a number of factors. Those factors may include, among other things and as applicable for the type of potential product, an assessment of the opportunities and risks of our product candidate, the design or results of studies or trials, the likelihood of approval, if necessary, by the USDA, the FDA or similar regulatory authorities outside the United States, the potential market for the subject product candidate, the costs and complexities of manufacturing and delivering such product candidate to patients, the potential of competing products and industry and market conditions generally.

Collaborations are complex and time-consuming to negotiate and document. We may not be able to negotiate collaborations on a timely basis, on acceptable terms, or at all. If we do enter into additional collaboration agreements, including out-licensing our lead product candidate, ONA-XR, the negotiated terms may force us to relinquish rights that diminish our potential profitability from development and commercialization of the subject product candidates or others. Such collaborations may also impact our ability to control the nature, timing and cadence of developing and commercializing the product candidates subject to such collaborations. If we are unable to enter into additional collaboration agreements, we may have to curtail the research and development of the product candidate for which we are seeking to collaborate, reduce or delay research and development programs, delay potential commercialization timelines, reduce the scope of any sales or marketing activities or undertake research, development or commercialization activities at our own expense.

Risks Related to Government Regulation

The FDA regulatory approval process is lengthy and time-consuming, and we may experience significant delays in the clinical development and regulatory approval of our product candidates.

The research, testing, manufacturing, labeling, approval, selling, import, export, marketing, and distribution of drug products, including biologics and pharmaceuticals, are subject to extensive regulation by the FDA and other regulatory authorities in the United States. We expect the novel nature of our product candidates to create further challenges in obtaining regulatory approval. For example, the FDA has limited experience with commercial development of anti-estrogen resistance inhibition therapies for cancer. The FDA may also require a panel of experts, referred to as an Advisory Committee, to deliberate on the adequacy of the safety and efficacy data to support licensure. The opinion of the Advisory Committee, although not binding, may have a significant impact on our ability to obtain licensure of the product candidates based on the completed clinical trials, as the FDA often makes decisions consistent with the Advisory Committee’s recommendations. Accordingly, the regulatory approval pathway for our product candidates may be uncertain, complex, expensive and lengthy, and approval may not be obtained.

We may also experience delays in completing planned clinical trials for a variety of reasons, including delays related to:

•obtaining regulatory authorization to begin a trial, if applicable;

•the availability of financial resources to commence and complete the planned trials;

•reaching agreement on acceptable terms with prospective CROs and clinical trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;

•obtaining approval at each clinical trial site by an independent institutional review board, or IRB;

•recruiting suitable patients to participate in a trial;

•having patients complete a trial, including having patients enrolled in clinical trials dropping out of the trial before the product candidate is manufactured and returned to the site, or return for post-treatment follow-up;

•clinical trial sites deviating from trial protocol or dropping out of a trial;

•addressing any patient safety concerns that arise during the course of a trial;

•adding new clinical trial sites; or

•manufacturing sufficient quantities of qualified materials under cGMPs and applying them on a patient by patient basis for use in clinical trials.

We could also encounter delays if physicians encounter unresolved ethical issues associated with enrolling patients in clinical trials of our product candidates in lieu of prescribing existing treatments that have established safety and efficacy profiles. Further, a clinical trial may be suspended or terminated by us, the IRBs for the institutions in which such trials are being conducted or by the FDA or other regulatory authorities due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a product candidate, changes in governmental regulations or administrative actions, lack of adequate funding to continue the clinical trial, or based on a recommendation by the Data Safety Monitoring Committee. The FDA’s review of our data of our ongoing clinical trials may, depending on the data, also result in the delay, suspension or termination of one or more clinical trials, which would also delay or prevent the initiation of our other planned clinical trials. If we experience termination of, or delays in the completion of, any clinical trial of our product candidates, the commercial prospects for our product candidates will be harmed, and our ability to generate product revenue will be delayed. In addition, any delays in completing our clinical trials will increase our costs, slow down our product development and approval process and jeopardize our ability to commence product sales and generate revenue.

Many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may ultimately lead to the denial of regulatory approval of our product candidates.

We expect that CLDN6xCD3 bsAb will be regulated as biological products, or biologics, and therefore they may be subject to competition sooner than anticipated.

The Biologics Price Competition and Innovation Act was enacted as part of the Affordable Care Act to establish an abbreviated pathway for the approval of biosimilar and interchangeable biological products. The regulatory pathway establishes legal authority for the FDA to review and approve biosimilar biologics, including the possible designation of a biosimilar as “interchangeable” based on its similarity to an approved biologic. Under the Biologics Price Competition and Innovation Act, an application for a biosimilar product cannot be approved by the FDA until 12 years after the reference product was approved under a BLA. The law is complex and is still being interpreted and implemented by the FDA. As a result, its ultimate impact, implementation, and meaning are subject to uncertainty. While it is uncertain when such processes intended to implement the Biologics Price Competition and Innovation Act may be fully adopted by the FDA, any such processes could have a material adverse effect on the future commercial prospects for our biological products.

We believe that CLDN6xCD3 bsAb, if approved in the United States as a biological product under a BLA should qualify for the 12-year period of exclusivity. However, there is a risk that this exclusivity could be shortened due to congressional action or otherwise, or that the FDA will not consider the subject product candidates to be

reference products for competing products, potentially creating the opportunity for generic competition sooner than anticipated. Moreover, the extent to which a biosimilar, once approved, will be substituted for any one of the reference products in a way that is similar to traditional generic substitution for non-biological products is not yet clear, and will depend on a number of marketplace and regulatory factors that are still developing.

The FDA may disagree with our regulatory plan and we may fail to obtain regulatory approval of our product candidates.

If and when our ongoing Phase 2 clinical trials for ONA-XR and planned clinical trials for our other initial product candidates are completed and, assuming positive data, we expect to advance to potential registrational trials. The general approach for FDA approval of a new biologic or drug is for the sponsor to provide dispositive data from two well-controlled, Phase 3 clinical studies of the relevant biologic or drug in the relevant patient population. Phase 3 clinical studies typically involve hundreds of patients, have significant costs and take years to complete. If the results from our clinical trials are sufficiently compelling, we intend to discuss with the FDA submission of a BLA or NDA, as applicable for the relevant product candidate. However, we do not have any agreement or guidance from the FDA that our regulatory development plans will be sufficient for submission of a BLA or NDA, as applicable for the relevant product candidate. For example, the FDA may require that we conduct a comparative trial against an approved therapy, which would significantly delay our development timelines and require substantially more resources.

The FDA may grant accelerated approval for our product candidates and, as a condition for accelerated approval, the FDA may require a sponsor of a drug or biologic receiving accelerated approval to perform post-marketing studies to verify and describe the predicted effect on irreversible morbidity or mortality or other clinical endpoint, and the drug or biologic may be subject to withdrawal procedures by the FDA that are more accelerated than those available for regular approvals. We believe an accelerated approval strategy is warranted given the limited alternatives for patients that our initial product candidates target, but the FDA may ultimately require a Phase 3 clinical trial prior to approval, particularly since our product candidates represent a novel treatment. In addition, the standard of care may change with the approval of new products in the same indications that we are studying. This may result in the FDA or other regulatory agencies requesting additional studies to show that our product candidate is superior to the new products.

Our clinical trial results may also not support approval. In addition, our product candidates could fail to receive regulatory approval for many reasons, including the following:

•the FDA or comparable foreign regulatory authorities may disagree with the design or implementation of our clinical trials;

•we may be unable to demonstrate to the satisfaction of the FDA or comparable foreign regulatory authorities that our product candidates are safe and effective for any of their proposed indications;

•the results of clinical trials may not meet the level of statistical significance required by the FDA or comparable foreign regulatory authorities for approval, including due to the heterogeneity of patient populations;

•we may be unable to demonstrate that our product candidates’ clinical and other benefits outweigh their safety risks;

•the FDA or comparable foreign regulatory authorities may disagree with our interpretation of data from preclinical studies or clinical trials;

•the data collected from clinical trials of our product candidates may not be sufficient to the satisfaction of the FDA or comparable foreign regulatory authorities to support the submission of a BLA or NDA, as applicable, or other comparable submission in foreign jurisdictions or to obtain regulatory approval in the United States or elsewhere;

•the FDA or comparable foreign regulatory authorities will review our manufacturing process and inspect our commercial manufacturing facility and may not approve our manufacturing process or facility; and

•the approval policies or regulations of the FDA or comparable foreign regulatory authorities may significantly change in a manner rendering our clinical data insufficient for approval.

Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not mean that we will be successful in obtaining regulatory approval of our product candidates in other jurisdictions.

Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not guarantee that we will be able to obtain or maintain regulatory approval in any other jurisdiction, while a failure or delay in obtaining regulatory approval in one jurisdiction may have a negative effect on the regulatory approval process in others. For example, even if the FDA grants marketing approval of a product candidate, comparable regulatory authorities in foreign jurisdictions must also approve the manufacturing, marketing and promotion of the product candidate in those countries. Approval procedures vary among jurisdictions and can involve requirements and administrative review periods different from, and greater than, those in the United States, including additional preclinical studies or clinical trials as clinical studies conducted in one jurisdiction may not be accepted by regulatory authorities in other jurisdictions. In many jurisdictions outside the United States, a product candidate must be approved for reimbursement before it can be approved for sale in that jurisdiction. In some cases, the price that we intend to charge for our products is also subject to approval.

We may also submit marketing applications in other countries. Regulatory authorities in jurisdictions outside of the United States have requirements for approval of product candidates with which we must comply prior to marketing in those jurisdictions. Obtaining foreign regulatory approvals and compliance with foreign regulatory requirements could result in significant delays, difficulties and costs for us and could delay or prevent the introduction of our products in certain countries. If we fail to comply with the regulatory requirements in international markets and/or receive applicable marketing approvals, our target market will be reduced and our ability to realize the full market potential of our product candidates will be harmed.

We will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense and we may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with our product candidates.

Any regulatory approvals that we receive for our product candidates will require surveillance to monitor the safety and efficacy of the product candidate. The FDA may also require a Risk Evaluation and Mitigation Strategy (“REMS”) in order to approve our product candidates, which could entail requirements for a medication guide, physician communication plans or additional elements to ensure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. In addition, if the FDA or a comparable foreign regulatory authority approves our product candidates, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion, import, export and recordkeeping for our product candidates will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and other post-marketing information and reports, registration, as well as continued compliance with cGMPs and GCPs for any clinical trials that we conduct post-approval. As such, we and our contract manufacturers will be subject to continual review and inspections to assess compliance with cGMP and adherence to commitments made in any BLA, other marketing application and previous responses to inspectional observations. Accordingly, we and others with whom we work must continue to expend time, money and effort in all areas of regulatory compliance, including manufacturing, production and quality control. In addition, the FDA could require us to conduct another study to obtain additional safety or biomarker information. Further, we will be required to comply with FDA promotion and advertising rules, which include, among others, standards for direct-to-consumer advertising, restrictions on promoting products for uses or in patient populations that are not described in the product’s approved uses (known as “off-label use”), limitations on industry-sponsored scientific and educational activities and requirements for promotional activities involving the internet and social media. Later discovery of previously unknown problems with our product candidates, including adverse events of unanticipated severity or frequency, or with our third-party suppliers or manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market studies or

clinical studies to assess new safety risks; or imposition of distribution restrictions or other restrictions under a risk evaluation and mitigation strategy program. Other potential consequences include, among other things:

•restrictions on the marketing or manufacturing of our product candidates, withdrawal of the product from the market or voluntary or mandatory product recalls;

•fines, warning letters or holds on clinical trials;

•refusal by the FDA to approve pending applications or supplements to approved applications filed by us or suspension or revocation of license approvals;

•product seizure or detention, or refusal to permit the import or export of our product candidates; and

•injunctions or the imposition of civil or criminal penalties.

The FDA’s and other regulatory authorities’ policies may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative or executive action, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and we may not achieve or sustain profitability.

Even if we obtain regulatory approval of our product candidates, the products may not gain market acceptance among physicians, patients, hospitals, cancer treatment centers and others in the medical community.

The use of progesterone receptor and protein inhibitors as potential cancer treatments are recent developments and may not become broadly accepted by physicians, patients, hospitals, cancer treatment centers and others in the medical community and we may not be able to convince them to use our product candidates for many reasons. Additional factors will influence whether our product candidates are accepted in the market, including:

•the clinical indications for which our product candidates are approved;

•physicians, hospitals, cancer treatment centers and patients considering our product candidates as a safe and effective treatment;

•the potential and perceived advantages of our product candidates over alternative treatments;

•the prevalence and severity of any side effects;

•product labeling or product insert requirements of the FDA or other regulatory authorities;

•limitations or warnings contained in the labeling approved by the FDA;

•the timing of market introduction of our product candidates as well as competitive products;

•the cost of treatment in relation to alternative treatments;

•the availability of coverage and adequate reimbursement by third-party payors and government authorities;

•the willingness of patients to pay out-of-pocket in the absence of coverage and adequate reimbursement by third-party payors and government authorities;

•relative convenience and ease of administration, including as compared to alternative treatments and competitive therapies; and

•the effectiveness of our sales and marketing efforts.

If our product candidates are approved but fail to achieve market acceptance among physicians, patients, hospitals, cancer treatment centers or others in the medical community, we will not be able to generate significant revenue. Even if our products achieve market acceptance, we may not be able to maintain that market acceptance over time if new products or technologies are introduced that are more favorably received than our products, are more cost effective or render our products obsolete.

Coverage and reimbursement may be limited or unavailable in certain market segments for our product candidates, which could make it difficult for us to sell our product candidates, if approved, profitably.

Successful sales of our product candidates, if approved, depend on the availability of coverage and adequate reimbursement from third-party payors including governmental healthcare programs, such as Medicare and Medicaid, managed care organizations and commercial payors, among others. Significant uncertainty exists as to the coverage and reimbursement status of any product candidates for which we obtain regulatory approval. In addition, because our product candidates represent new approaches to the treatment of cancer, we cannot accurately estimate the potential revenue from our product candidates.

Patients who are provided medical treatment for their conditions generally rely on third-party payors to reimburse all or part of the costs associated with their treatment. Obtaining coverage and adequate reimbursement from third-party payors is critical to new product acceptance.

Third-party payors decide which drugs and treatments they will cover and the amount of reimbursement. Reimbursement by a third-party payor may depend upon a number of factors, including, but not limited to, the third-party payor’s determination that use of a product is:

•a covered benefit under its health plan;

•safe, effective and medically necessary;

•appropriate for the specific patient;

•cost-effective; and

•neither experimental nor investigational.

Obtaining coverage and reimbursement of a product from a government or other third-party payor is a time-consuming and costly process that could require us to provide to the payor supporting scientific, clinical and cost-effectiveness data for the use of our products. Even if we obtain coverage for a given product, if the resulting reimbursement rates are insufficient, hospitals may not approve our product for use in their facility or third-party payors may require co-payments that patients find unacceptably high. Patients are unlikely to use our product candidates unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of our product candidates. Separate reimbursement for the product itself may or may not be available. Instead, the hospital or administering physician may be reimbursed only for providing the treatment or procedure in which our product is used. Further, from time to time, the Centers for Medicare & Medicaid Services, or the CMS, revises the reimbursement systems used to reimburse health care providers, including the Medicare Physician Fee Schedule and Outpatient Prospective Payment System, which may result in reduced Medicare payments. In some cases, private third-party payers rely on all or portions of Medicare payment systems to determine payment rates. Changes to government healthcare programs that reduce payments under these programs may negatively impact payments from private third-party payers, and reduce the willingness of physicians to use our product candidates.

In the United States, no uniform policy of coverage and reimbursement for products exists among third-party payors. Therefore, coverage and reimbursement for products can differ significantly from payor to payor. Further, one payor’s determination to provide coverage for a product does not assure that other payors will also provide coverage for the product. Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to realize an appropriate return on our investment in product development.

We intend to seek approval to market our product candidates in both the United States and in selected foreign jurisdictions. If we obtain approval in one or more foreign jurisdictions for our product candidates, we will be

subject to rules and regulations in those jurisdictions. In some foreign countries, particularly those in Europe, the pricing of drugs and biologics is subject to governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time after obtaining marketing approval of a product candidate. Some of these countries may require the completion of clinical trials that compare the cost-effectiveness of a particular product candidate to currently available therapies. Other member states allow companies to fix their own prices for medicines, but monitor and control company profits. The downward pressure on health care costs has become very intense. As a result, increasingly high barriers are being erected to the entry of new products. In addition, in some countries, cross-border imports from low-priced markets exert a commercial pressure on pricing within a country.

The marketability of any product candidates for which we receive regulatory approval for commercial sale may suffer if government and other third-party payors fail to provide coverage and adequate reimbursement. We expect downward pressure on pharmaceutical pricing to continue. Further, coverage policies and third-party reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for one or more products for which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

The advancement of healthcare reform may negatively impact our ability to sell our product candidates, if approved, profitably.

In the United States and other jurisdictions, there have been, and we expect there will continue to be, a number of legislative and regulatory changes and proposed changes to the healthcare system that could affect our future results of operations. In particular, there have been and continue to be a number of initiatives at the U.S. federal and state levels that seek to reduce healthcare costs and improve the quality of healthcare. For example, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively the ACA, was enacted, which substantially changed the way healthcare is financed by both governmental and private payors. Among the provisions of the ACA of importance to the pharmaceutical and biotechnology industries, which includes biologics, are the following:

•manufacturers and importers of certain biologics with annual sales of more than $5 million made to or covered by specified federal healthcare programs are required to pay an annual, nondeductible fee according to their market share of all such sales;

•an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program, to 23.1% of the average manufacturer price for most branded drugs, biologics,and biosimilars and to 13.0% for generic drug, and cap of the total rebate amount for innovator drugs at 100% of the Average Manufacturer Price, or AMP;

•a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for certain drugs and biologics, including our product candidates, that are inhaled, infused, instilled, implanted, or injected;

•extension of manufacturers’ Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed care organizations;

•expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to additional individuals and by adding new mandatory eligibility categories for individuals with income at or below 133% of the federal poverty level, thereby potentially increasing manufacturers’ Medicaid rebate liability;

•expansion of the entities eligible for discounts under the Public Health program, commonly referred to as the “340B Program;”

•a new requirement to annually report drug samples that manufacturers and distributors provide to physicians, also known as the “Physician Payments Sunshine Act;”

•a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research, along with funding for such research;

•establishment of a Center for Medicare Innovation at CMS to test innovative payment and service delivery models to lower Medicare and Medicaid spending; and

•a licensure framework for follow-on biologic products.

Since its enactment, there have been judicial and Congressional challenges to certain aspects of the ACA, and we expect there will be additional challenges and amendments to the ACA in the future. For example, legislation enacted in 2017 informally titled the Tax Cuts and Jobs Act of 2017, repealed the tax-based shared responsibility payment imposed by the ACA on certain individuals who fail to maintain qualifying health coverage that is commonly referred to as the “individual mandate.” In December 2019, a U.S. District Court upheld a ruling that the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. In November 2020, the Supreme Court of the United States heard oral arguments in the appeal of this case, but it is uncertain when the Supreme Court will rule on this case. It is unclear how this and other efforts to challenge, repeal, or replace the ACA will impact the ACA or our business.

In addition, other legislative changes have been proposed and adopted in the United States since the ACA was enacted which, among other things, have reduced Medicare payments to several types of providers, including hospitals and cancer treatment centers.

These new laws or any other similar laws introduced in the future, as well as regulatory actions that may be taken by CMS, may result in additional reductions in Medicare and other healthcare funding, which could negatively affect our customers and accordingly, our financial operations. Moreover, payment methodologies may be subject to changes in healthcare legislation and regulatory initiatives. Additionally, individual states in the United States have passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing and costs. Similar developments have occurred outside of the United States, including in the European Union where healthcare budgetary constraints have resulted in restrictions on the pricing and reimbursement of medicines by relevant health service providers.

To obtain reimbursement or pricing approval in some European Union member states, we may be required to conduct studies that compare the cost-effectiveness of our product candidates to other therapies that are considered the local standard of care. It is also possible that additional governmental action is taken in response to address the COVID-19 pandemic. We cannot predict the likelihood, nature, or extent of government regulation that may arise from future legislation or administrative action in the United States, particularly as a result of the recent presidential election, or any other jurisdiction. If we or any third parties we may engage are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we or such third parties are not able to maintain regulatory compliance, our product candidates may lose any regulatory approval that may have been obtained and we may not achieve or sustain profitability.

Risks Related to Intellectual Property

Patents and patent applications involve highly complex legal and factual questions, which, if determined adversely to us, could negatively impact our business position.

The patent positions of biopharmaceutical companies and other actors in our fields of business can be highly uncertain and typically involve complex scientific, legal and factual analyses. In particular, the interpretation and breadth of claims allowed in some patents covering biopharmaceutical compositions may be uncertain and difficult to determine, and are often affected materially by the facts and circumstances that pertain to the patented compositions and the related patent claims. The standards of the United States Patent and Trademark Office (the USPTO) and its foreign counterparts are sometimes uncertain and could change in the future.

Consequently, the issuance and scope of patents cannot be predicted with certainty. Patents, if issued, may be challenged, invalidated or designed around. U.S. patents and patent applications may also be subject to interference

or derivation proceedings, and U.S. patents may be subject to reexamination, post-grant review and/or inter parties review proceedings in the USPTO.

International patents may also be subject to opposition or comparable proceedings in the corresponding international patent office, which could result in either loss of the patent or denial of the patent application, or loss or reduction in the scope of one or more of the claims of the patent or patent application. In addition, such interference, derivation, reexamination, post-grant review, inter parties review and opposition proceedings may be costly. Accordingly, rights under any issued patents may not provide us with sufficient protection against competitive products or processes.

Furthermore, even if not challenged, our patents and patent applications may not adequately protect our technology and any product candidates or products that we develop alone or with collaborators or prevent others from designing their products to avoid being covered by our claims. If the breadth or strength of protection provided by the patents and patent applications that we hold with respect to our product candidates or potential products is threatened, it could dissuade companies from collaborating with us to develop, and could threaten our or their ability to successfully commercialize, such product candidates or potential products.

In addition, changes in, or different interpretations of, patent laws in the United States and other countries may permit others to use our discoveries or to develop and commercialize our technology and product candidates or products without providing any compensation to us, or may limit the scope of patent protection that we are able to obtain. The laws of some countries do not protect intellectual property rights to the same extent as U.S. laws, and those countries may lack adequate rules and procedures for defending our intellectual property rights.

Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and/or applications will be due to be paid to the USPTO and various governmental patent agencies outside of the United States in several stages over the lifetime of the patents and/or applications. We rely on our outside counsel and employ an outside firm to pay these fees due to USPTO and non-US patent agencies. The USPTO and various non-US governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process. Although an inadvertent lapse can be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which non-compliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, our competitors might be able to enter the market which would have a material adverse effect on our business.

If the patent applications we hold or have in-licensed with respect to our current and future research and development programs and product candidates fail to issue, if their validity, breadth or strength of protection is threatened, or if they fail to provide meaningful exclusivity for our technology or any products and product candidates that we or our collaborators may develop, it could dissuade companies from collaborating with us to develop product candidates, encourage competitors to develop competing products or technologies and threaten our or our collaborators’ ability to commercialize future product candidates. Any such outcome could have a material adverse effect on our business.

Our ability to compete effectively in our markets may decline if we do not adequately protect our proprietary rights, and our proprietary rights do not necessarily address all potential threats to our competitive advantages.

We rely on patent protection as well as trademark, trade secret and other intellectual property rights protection and contractual restrictions to protect ONA-XR, CLDN6xCD3 bsAb and other product candidates. Our commercial success depends upon obtaining and maintaining proprietary rights to our intellectual property estate, including rights relating to ONA-XR, CLDN6xCD3 bsAb and other product candidates, as well as successfully defending these rights against third-party challenges and successfully enforcing these rights to prevent third-party infringement. We will only be able to protect ONA-XR, CLDN6xCD3 bsAb and other product candidates from unauthorized use by third parties to the extent that valid and enforceable patents or effectively protected trade secrets cover them.

Our ability to obtain and maintain patent protection for ONA-XR, CLDN6xCD3 bsAb and other product candidates is uncertain due to a number of factors, including the following factors:

•we may not have been the first to invent the technology covered by our pending patent applications or issued patents;

•we may not be the first to file patent applications covering product candidates, including their compositions or methods of use, as patent applications in the United States and most other countries are confidential for a period of time after filing;

•our compositions and methods may not be patentable;

•our disclosures in patent applications may not be sufficient to meet the statutory requirements for patentability;

•any or all of our pending patent applications may not result in issued patents;

•others may independently develop identical, similar or alternative technologies, products or compositions, or methods of use thereof;

•others may design around our patent claims to produce competitive technologies or products that fall outside of the scope of our patents;

•we may fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection;

•we may not seek or obtain patent protection in countries and jurisdictions that may eventually provide us a significant business opportunity;

•we may decide not to maintain or pursue patents and patent applications that, at some point in time, may cover our products, potential products, or product candidates;

•any patents issued to us may not provide a basis for commercially viable products, may not provide any competitive advantages or may be successfully challenged by third parties;

•others may identify prior art or other bases upon which to challenge and ultimately invalidate our patents or otherwise render them unenforceable;

•our representatives or their agents may fail to apply for patents in a timely fashion; and

•despite our efforts to enter into agreements with employees, consultants, collaborators, and advisors to confirm ownership and chain of title in patents and patent applications, an inventorship or ownership dispute could arise that may permit one or more third parties to practice our technologies or enforce our patent rights, including possible efforts to enforce patent rights against us.

Even if we have or obtain patents covering ONA-XR, CLDN6xCD3 bsAb or any other product candidates or compositions, others may have filed, and in the future may file, patent applications covering compositions, products or methods that are similar or identical to ours, which could materially affect our ability to successfully develop any product candidates or to successfully commercialize any approved products alone or with collaborators. In addition, because patent applications can take many years to issue, there may be currently pending applications unknown to us that may later result in issued patents that may cover ONA-XR, CLDN6xCD3 bsAb or any other product candidates or compositions. These patent applications may have priority over patent applications filed by us.

The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our owned and licensed patents may be challenged in the courts or patent offices in the United States and abroad. Such challenges may result in loss of exclusivity or freedom to operate or in patent claims being narrowed, invalidated or held unenforceable, in whole or in part, which could limit our ability to stop others from using or commercializing

similar or identical technology and products, or limit the duration of the patent protection of our technology and products.

In the United States, the natural expiration of a patent is generally 20 years after it is filed. Various extensions may be available; however the life of a patent, and the protection it affords, is limited.

Without patent protection for current or future product candidates, we may be open to competition from generic or biosimilar versions of such potential products. Given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to those we or our collaborators may develop.

In addition, we also try to protect our trade secrets, know-how and other proprietary information through non-disclosure and confidentiality provisions in our agreements with parties who have access to them, such as our employees, consultants and research partners. Such agreements may not be enforceable or may not provide meaningful protection for our trade secrets, know-how and/or other proprietary information in the event of unauthorized uses or disclosure or other breaches of the provisions, and we may not be able to prevent such unauthorized uses or disclosure. Moreover, if a party having an agreement with us has an overlapping or conflicting obligation to a third party, our rights in and to certain intellectual property could be undermined. Monitoring unauthorized and inadvertent disclosure and uses is difficult, and we do not know whether the steps we have taken to prevent such disclosure and uses are, or will be, adequate. In addition, monitoring unauthorized disclosure and uses of our trade secrets is difficult, and we do not know whether the steps we have taken to prevent such disclosure and uses are, or will be, adequate. If we were to enforce a claim that a third-party had illegally obtained and was using our trade secrets, it would be expensive and time-consuming, and the outcome would be unpredictable, and any remedy may be inadequate. In addition, courts outside the United States may be less willing to protect trade secrets.

We rely on trade secrets to protect our proprietary technologies, especially where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to protect. We rely in part on confidentiality agreements with our employees, consultants, outside scientific collaborators, sponsored researchers and other advisors to protect our trade secrets and other proprietary information. These agreements may not effectively prevent disclosure of confidential information and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. In addition, others may independently discover our trade secrets and proprietary information. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection could adversely affect our competitive business position.

Because we may rely on third parties to manufacture our potential product candidates, and because we collaborate with various organizations and academic institutions on the advancement of our current and potential product candidates, we must, at times, share trade secrets with them. We seek to protect our proprietary technology in part by entering into confidentiality agreements and, if applicable, material transfer agreements, collaborative research agreements, consulting agreements or other similar agreements with our manufacturers, collaborators, advisors, employees and consultants prior to beginning research or disclosing proprietary information. These agreements typically limit the rights of the third parties to use or disclose our confidential information, such as trade secrets. Despite the contractual provisions employed when working with third parties, the need to share trade secrets and other confidential information increases the risk that such trade secrets become known by our competitors, are inadvertently incorporated into the technology of others, are used inappropriately to create new inventions or are disclosed or used in violation of these agreements. Given that our proprietary position is based, in part, on our know-how and trade secrets, a competitor’s discovery of our trade secrets or other unauthorized use or disclosure would impair our competitive position and may have a material adverse effect on our business.

If we fail to comply with our obligations in the agreements under which we license intellectual property rights from third parties or otherwise experience disruptions to our business relationships with our licensors, we could lose license rights that are important to our business.

We are a party to intellectual property license agreements that are important to our business and expect to enter into additional license agreements in the future. Our existing license agreements impose, and we expect that future license agreements will impose, various diligence, milestone payment, royalty and other obligations on us. Additionally, we may need to outsource and rely on third parties for many aspects of the development, sales and marketing of any products covered under our current and future license agreements. Delay or failure by these third parties could adversely affect the continuation of our license agreements with our licensors. If we fail to comply with any of our obligations under these agreements, or we are subject to a bankruptcy, our licensors may have the right to terminate the license, in which event we would not be able to market any products covered by the license.

In some cases, patent prosecution of our licensed technology is controlled solely by the licensor. If such licensor fails to obtain and maintain patent or other protection for the proprietary intellectual property we license from such licensor, we could lose our rights to such intellectual property or the exclusivity of such rights, and our competitors could market competing products using such intellectual property. In that event, we may be required to expend significant time and resources to develop or license replacement technology.

If we are unable to do so, we or our collaborators may be unable to develop or commercialize the affected product candidates, which could harm our business significantly. In other cases, we control the prosecution of patents resulting from licensed technology. In the event we breach any of our obligations related to such prosecution, we may incur significant liability to our licensing partners.

Licensing of intellectual property is of critical importance to our business and involves complex legal, business and scientific issues and is complicated by the rapid pace of scientific discovery in our industry. Disputes may arise regarding intellectual property subject to a licensing agreement, including:

•the scope of rights granted under the license agreement and other interpretation-related issues;

•the extent to which our technology and processes infringe intellectual property of the licensor that is not subject to the licensing agreement;

•the sublicensing of patent and other rights under our collaborative development relationships;

•our diligence obligations under the license agreement and what activities satisfy those diligence obligations;

•the ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and us and our partners; and

•the priority of invention of patented technology.

If disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates.

If we do not obtain patent term extension in the United States under the Hatch-Waxman Act and in foreign countries under similar legislation with respect to our product candidates, thereby potentially extending the term of marketing exclusivity for such product candidates, our business may be harmed.

In the United States, a patent that covers an FDA-approved drug or biologic may be eligible for a term extension designed to restore the period of the patent term that is lost during the premarket regulatory review process conducted by the FDA. Depending upon the timing, duration and conditions of FDA marketing approval of our product candidates, one or more of our U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, or the Hatch-Waxman Act, which permits a patent term extension of up to five years for a patent covering an approved product as compensation for effective patent term lost during product development and the FDA regulatory review process.

In the European Union, our product candidates may be eligible for term extensions based on similar legislation. In either jurisdiction, however, we may not receive an extension if we fail to apply within applicable deadlines, fail to apply prior to expiration of relevant patents or otherwise fail to satisfy applicable requirements.

Even if we are granted such extension, the duration of such extension may be less than our request. If we are unable to obtain a patent term extension, or if the term of any such extension is less than our request, the period during which we can enforce our patent rights for that product will be in effect shortened and our competitors may obtain approval to market competing products sooner. The resulting reduction of years of revenue from applicable products could be substantial.

We may not be able to protect our intellectual property rights throughout the world.

Filing, prosecuting and defending patents on product candidates in all countries throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the United States can be less extensive than those in the United States. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States, or from selling or importing products made using our inventions in and into the United States or other jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and further, may export otherwise infringing products to territories where we have patent protection, but enforcement is not as strong as that in the United States. These products may compete with our products and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets and other intellectual property protection, particularly those relating to biotechnology products, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our proprietary rights generally. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license.

Third parties may assert claims against us alleging infringement of their patents and proprietary rights, or we may need to become involved in lawsuits to defend or enforce our patents, either of which could result in substantial costs or loss of productivity, delay or prevent the development and commercialization of product candidates, prohibit our use of proprietary technology or sale of potential products or put our patents and other proprietary rights at risk.

Our commercial success depends in part upon our ability to develop, manufacture, market and sell product candidates without alleged or actual infringement, misappropriation or other violation of the patents and proprietary rights of third parties. Litigation relating to infringement or misappropriation of patent and other intellectual property rights in the pharmaceutical, biotechnology is common, including patent infringement lawsuits, and such interference, derivation, reexamination, post-grant review, inter parties review and opposition proceedings before the USPTO and corresponding international patent offices.

The various markets in which we plan to operate are subject to frequent and extensive litigation regarding patents and other intellectual property rights. In addition, many companies in intellectual property-dependent industries, including the biotechnology and pharmaceutical industries, have employed intellectual property litigation as a means to gain an advantage over their competitors.

Numerous United States, EU and other internationally issued patents and pending patent applications, which are owned by third parties, exist in the fields in which we and our collaborators are developing product candidates, and

as the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that our product candidates may be subject to claims of infringement of the intellectual property rights of third parties.

As a result of any patent infringement claims, or in order to avoid any potential infringement claims, we may choose to seek, or be required to seek, a license from a third party, which may require payment of substantial royalties or fees, or require us to grant a cross-license under our intellectual property rights.

These licenses may not be available on reasonable terms or at all. Even if a license can be obtained on reasonable terms, the rights may be nonexclusive, which would give our competitors access to the same intellectual property rights. If we are unable to enter into a license on acceptable terms, we or our collaborators could be prevented from commercializing one or more product candidates, or forced to modify such product candidates, or to cease some aspect of our business operations, which could harm our business significantly.

We or our collaborators might also be forced to redesign or modify our technology or product candidates so that we no longer infringe the third-party intellectual property rights, which may result in significant cost or delay to us, or which redesign or modification could be impossible or technically infeasible. Even if we were ultimately to prevail, any of these events could require us to divert substantial financial and management resources that we would otherwise be able to devote to our business.

Further, if a patent infringement suit is brought against us, our collaborators or our third-party service providers, our development, manufacturing or sales activities relating to the product or product candidate that is the subject of the suit may be delayed or terminated. In addition, defending such claims has in the past and may in the future cause us to incur substantial expenses and, if successful, could cause us to pay substantial damages if we are found to be infringing a third party’s patent rights.

These damages potentially include increased damages and attorneys’ fees if we are found to have infringed such rights willfully. Some claimants may have substantially greater resources than we do and may be able to sustain the costs of complex intellectual property litigation to a greater degree and for longer periods of time than we could. In addition, patent holding companies that focus solely on extracting royalties and settlements by enforcing patent rights may target us.

We may in the future be subject to third-party claims and similar adversarial proceedings or litigation in other jurisdictions regarding our infringement of the patent rights of third parties. Even if such claims are without merit, a court of competent jurisdiction could hold that these third-party patents are valid, enforceable and infringed, and the holders of any such patents may be able to block our or our collaborators’ ability to further develop or commercialize the applicable product candidate unless we obtain a license under the applicable patents, or until such patents expire or are finally determined to be invalid or unenforceable.

Similarly, if any third-party patents were held by a court of competent jurisdiction to cover aspects of our technologies, compositions, formulations, or methods of treatment, prevention or use, the holders of any such patents may be able to prohibit our use of those technologies, compositions, formulations, methods of treatment, prevention or use or other technologies, effectively blocking our or our collaborators’ ability to develop and commercialize the applicable product candidate until such patent expires or is finally determined to be invalid or unenforceable or unless we or our collaborators obtain a license.

Competitors may infringe our patents. In the event of infringement or unauthorized use, we may file one or more infringement lawsuits, which can be expensive and time-consuming. An adverse result in any such litigation proceedings could put one or more of our patents at risk of being invalidated, being found to be unenforceable, and/or being interpreted narrowly and could put our patent applications at risk of not issuing and/or could impact the validity or enforceability positions of our other patents. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation.

Some of our competitors may be able to sustain the costs of complex intellectual property litigation more effectively than we can because they have substantially greater resources. In addition, intellectual property litigation, regardless of its outcome, may cause negative publicity, adversely impact prospective customers, cause product

shipment delays or prohibit us from manufacturing, marketing or otherwise commercializing our products, services and technology.

Any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise additional funds or otherwise have a material adverse effect on our business, results of operation, financial condition or cash flows.

Changes in U.S. patent law could diminish the value of patents in general, thereby impairing our ability to protect our products.

The United States has enacted and is currently implementing wide-ranging patent reform legislation. Recent U.S. Supreme Court rulings have narrowed the scope of patent protection available in certain circumstances and weakened the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on decisions by the U.S. Congress, the federal courts and the USPTO, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future.

Risks Related to the Market for Our Common Stock

Our common stock may be volatile or may decline regardless of our operating performance, and you may not be able to resell your shares at or above the initial public offering price.

The market price for our common stock is likely to be volatile, in part because our shares have been traded publicly for a short time. In addition, the market price of our common stock may fluctuate significantly in response to several factors, most of which we cannot control, including:

•quarterly variations in our operating results compared to market expectations;

•adverse publicity about us, the industries we participate in or individual scandals;

•announcements of new offerings or significant price reductions by us or our competitors;

•stock price performance of our competitors;

•fluctuations in stock market prices and volumes;

•changes in senior management or key personnel;

•changes in financial estimates by securities analysts;

•the market’s reaction to our reduced disclosure as a result of being an “emerging growth company” under the JOBS Act;

•negative earnings or other announcements by us or our competitors;

•defaults on indebtedness, incurrence of additional indebtedness, or issuances of additional capital stock;

•global economic, legal and regulatory factors unrelated to our performance; and

•the other factors listed in this “Risk Factors” section.

Volatility in the market price of our common stock may prevent investors from being able to sell their shares at or above their purchase price. As a result, you may suffer a loss on your investment.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, the market price for the shares and trading volume could decline.

The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish about us or our business. If research analysts do not establish and maintain adequate research coverage or if one or more of the analysts who covers us downgrades our common stock or publishes inaccurate or unfavorable research about our business, the market price for our common stock would likely decline. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, we could lose visibility in the financial markets, which, in turn, could cause the market price or trading volume for our common stock to decline.

We will require additional capital to fund our operations, and if we fail to obtain necessary financing, we may not be able to advance or complete the development and commercialization of our product candidates.

Our future funding requirements, both near and long-term, will depend on many factors, including, but not limited to:

•initiation, progress, timing, costs and results of preclinical studies and clinical trials, including patient enrollment in such trials, for ONA-XR, CLDN6xCD3 bsAb or any other future product candidates;

•clinical development plans we establish for ONA-XR, CLDN6xCD3 bsAb and any other future product candidates;

•obligation to make milestone, royalty and non-royalty sublicense receipt payments to third-party licensors, if any, under our licensing agreements;

•number and characteristics of product candidates that we discover or in-license and develop;

•outcome, timing and cost of regulatory review by the FDA and comparable foreign regulatory authorities, including the potential for the FDA or comparable foreign regulatory authorities to require that we perform more studies than those that we currently expect;

•costs of filing, prosecuting, defending and enforcing any patent claims and maintaining and enforcing other intellectual property rights;

•effects of competing technological and market developments;

•costs and timing of the implementation of commercial-scale manufacturing activities; and

•costs and timing of establishing sales, marketing and distribution capabilities for any product candidates for which we may receive regulatory approval.

If we are unable to expand our operations or otherwise capitalize on our business opportunities due to a lack of capital, our ability to become profitable will be compromised.

Our directors, executive officers and certain stockholders own a significant percentage of our common stock and, if they choose to act together, will be able to exert significant control over matters subject to stockholder approval.

Our directors, executive officers, and stockholders affiliated with our directors and executive officers beneficially own approximately 6.8% of the voting power of our outstanding common stock. Therefore, they have the ability to substantially influence us through their ownership position. For example, these holders may be able to control elections of directors, amendments of our organizational documents, or approval of any merger, sale of assets, or other major corporate transaction. The interests of these holders may not always coincide with our corporate interests or the interests of other stockholders, and they may act in a manner with which you may not agree or that may not be in the best interests of our other stockholders. So long as they continue to own a significant amount of our equity, these holders will be able to strongly influence or effectively control our decisions.

We do not expect to pay dividends in the foreseeable future, and you must rely on price appreciation of your shares for return on your investment.

We have paid no cash dividends on any class of our stock to date and we do not anticipate paying cash dividends in the near term. For the foreseeable future, we intend to retain any earnings to finance the development and expansion of our business, and we do not anticipate paying any cash dividends on our stock. Accordingly, investors must be prepared to rely on sales of their shares after price appreciation to earn an investment return, which may never occur. Investors seeking cash dividends should not purchase our shares. Any determination to pay dividends in the future will be made at the discretion of our board of directors and will depend on our results of operations, financial condition, contractual restrictions, restrictions imposed by applicable law and other factors our board deems relevant.

We may issue additional debt and equity securities, which are senior to our common stock as to distributions and in liquidation, which could materially adversely affect the market price of our common stock.

In the future, we may attempt to increase our capital resources by entering into additional debt or debt-like financing that is secured by all or up to all of our assets, or issuing debt or equity securities, which could include issuances of commercial paper, medium-term notes, senior notes, subordinated notes or shares. In the event of our liquidation, our lenders and holders of our debt securities would receive a distribution of our available assets before distributions to our stockholders. In addition, any additional preferred stock, if issued by our company, may have a preference with respect to distributions and upon liquidation, which could further limit our ability to make distributions to our stockholders. Because our decision to incur debt and issue securities in our future offerings will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings and debt financing.

Further, market conditions could require us to accept less favorable terms for the issuance of our securities in the future. Thus, you will bear the risk of our future offerings reducing the value of your common stock and diluting your interest in our company.

We are subject to ongoing public reporting requirements that are less rigorous than Exchange Act rules for companies that are not emerging growth companies and our stockholders could receive less information than they might expect to receive from more mature public companies.

We are required to publicly report on an ongoing basis as an “emerging growth company” (as defined in the JOBS Act) under the reporting rules set forth under the Exchange Act. For so long as we remain an emerging growth company, we may take advantage of certain exemptions from various reporting requirements that are applicable to other Exchange Act reporting companies that are not emerging growth companies, including but not limited to:

•not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act;

•being permitted to comply with reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and

•being exempt from the requirement to hold a non-binding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

In addition, Section 107 of the JOBS Act also provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. In other words, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to take advantage of the benefits of this extended transition period. Our financial statements may therefore not be comparable to those of companies that comply with such new or revised accounting standards.

We expect to take advantage of these reporting exemptions until we are no longer an emerging growth company. We will remain an emerging growth company until October 19, 2026, although if the market value of our

common stock that is held by non-affiliates exceeds $700 million as of any June 30 before that time, we would cease to be an emerging growth company as of the following December 31.

Because we are subject to ongoing public reporting requirements that are less rigorous than Exchange Act rules for companies that are not emerging growth companies, our stockholders could receive less information than they might expect to receive from more mature public companies. We cannot predict if investors will find our common stock less attractive if we elect to rely on these exemptions, or if taking advantage of these exemptions would result in less active trading or more volatility in the price of our common stock.

We have material weaknesses in our internal control over financial reporting and will need to hire additional personnel and design and implement proper and effective internal control over financial reporting. We may identify additional material weaknesses in the future that may cause us to fail to meet our reporting obligations or result in material misstatements in our financial statements. If we fail to remediate our material weaknesses, we may not be able to report our financial results accurately or to prevent fraud.

Our management is responsible for establishing and maintaining internal control over financial reporting, disclosure controls, and compliance with the other requirements of the Sarbanes-Oxley Act and the rules promulgated by the SEC thereunder. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with US GAAP. The PCAOB defines a material weakness as a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of annual or interim financial statements will not be prevented, or detected and corrected, on a timely basis.

During the preparation of our consolidated financial statements for the years ended December 31, 2019 and 2020, we and our independent registered public accounting identified a material weakness related to the lack of an appropriate review of the internally prepared financial statements which resulted in the Company’s failure to timely detect and correct certain misstatements within the consolidated financial statements. Such misstatements have been corrected in the accompanying consolidated financial statements for the years ended December 31, 2019 and 2020. We also identified a material weakness as it relates to a lack of adequate segregation of accounting functions.

Management will aim to remediate the material weaknesses described above through hiring additional qualified accounting and financial reporting personnel, and designing and implementing financial reporting systems, processes, policies and internal control. However, we will not be able to fully remediate these material weaknesses until these steps have been completed and are functioning effectively, which may expose us to errors, losses or fraud until remediated. In addition, we cannot at this time provide an estimate of the costs we expect to incur or the expected timeline in connection with implementing our remediation plan. These remediation measures may be time-consuming and costly, and might place significant demands on our financial and operational resources. If we are unable to successfully remediate these material weaknesses or successfully supervise and rely on outside advisors with expertise in these matters to assist us in the preparation of our financial statements, our financial statements could contain material misstatements that, when discovered in the future, could cause us to fail to meet our future reporting obligations and cause the price of our common stock to decline.

Our independent registered public accounting firm has included an explanatory paragraph relating to our ability to continue as a going concern in its report on our audited consolidated financial statements for the year ended December 31, 2020 included in this prospectus.

The report from our independent registered public accounting firm for the year ended December 31, 2020 includes an explanatory paragraph stating that our recurring losses and negative cash flows from operations, working capital deficit and accumulated deficit raise substantial doubt about our ability to continue as a going concern. We will continue to seek to raise additional capital in the future through equity and/or debt financings, partnerships, collaborations, or other sources to carry out the Company’s planned development activities. If additional capital is not available when required, the Company may need to delay or curtail its operations until such funding is received. Future reports from our independent registered public accounting firm may also contain statements expressing substantial doubt about our ability to continue as a going concern.

Raising additional capital may cause dilution to our stockholders, including purchasers of common stock in this offering, restrict our operations or require us to relinquish rights to our technologies or product candidates.

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity and/or debt financings and collaborations, licensing agreements or other strategic arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted, and the terms of such securities may include liquidation or other preferences that adversely affect your rights as a common stockholder.

To the extent that we raise additional capital through debt financing, it would result in increased fixed payment obligations and a portion of our operating cash flows, if any, being dedicated to the payment of principal and interest on such indebtedness. In addition, debt financing may involve agreements that include restrictive covenants that impose operating restrictions, such as restrictions on the incurrence of additional debt, the making of certain capital expenditures or the declaration of dividends.

To the extent we raise additional capital through arrangements with collaborators or otherwise, we may be required to relinquish some of our technologies, research programs, product development activities, product candidates and/or future revenue streams, license our technologies and/or product candidates on unfavorable terms or otherwise agree to terms unfavorable to us. Furthermore, any capital raising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to advance research programs, product development activities or product candidates.

General Risk Factors

We incur increased costs as a result of becoming a public company and in the administration of our organizational structure.

As a public company, we have incurred significant legal, accounting, insurance, and other expenses , including costs associated with public company reporting requirements. We also have incurred and will incur costs associated with the Sarbanes-Oxley Act and related rules implemented by the SEC and ongoing periodic expenses in connection with the administration of our organizational structure. The expenses incurred by public companies generally for reporting and corporate governance purposes have been increasing. We expect these rules and regulations to increase our legal and financial compliance costs and to make some activities more time-consuming and costly, although we are currently unable to estimate these costs with any significant degree of certainty. In estimating these costs however, we took into account expenses related to insurance, legal, accounting, and compliance activities, as well as other expenses not currently incurred. These laws and regulations could also make it more difficult or costly for us to obtain certain types of insurance, including director and officer liability insurance, and we may be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. These laws and regulations could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees or as our executive officers. Furthermore, if we are unable to satisfy our obligations as a public company, we could be subject to delisting of our common stock, fines, sanctions and other regulatory action and potentially civil litigation.

We are subject to complex tax rules relating to our business, and any audits, investigations or tax proceedings could have a material adverse effect on our business, results of operations and financial condition.

We are subject to income and non-income taxes in the United States and Ireland, as well as the tax laws and regulations related to such matters. Tax accounting and compliance often involves complex issues, and judgment and interpretation is required in determining our provision for income taxes and other tax liabilities as well as the application of tax laws and regulations. We could become subject to income and non-income taxes in non-US jurisdictions other than Ireland as well. In addition, many jurisdictions have detailed transfer pricing rules, which require that all transactions with related parties be priced using arm’s length pricing principles within the meaning of such rules. The application of such transfer pricing rules, as well as of withholding taxes, goods and services taxes, sales taxes and other taxes is not always clear and we may be subject to tax audits relating to such rules or taxes. We believe that our tax positions are reasonable, and our tax provisions and reserves are adequate to cover any potential liability. We are also currently not subject to any tax audits.

However, various items cannot be accurately forecasted and future events may be treated as discrete to the period in which they occur. In addition, the Internal Revenue Service or other taxing authorities may disagree with our positions. In addition, existing tax laws, statutes, rules, regulations or ordinances could be interpreted, changed, modified or applied adversely to us (possibly with retroactive effect). If the Internal Revenue Service or any other tax authorities were successful in challenging our positions, or existing tax laws, statutes, rules, regulations or ordinances are so interpreted, changed or modified, we may be liable for additional tax and penalties and interest related thereto or other taxes, as applicable, in excess of any reserves established therefor, which may have a significant impact on our results and operations and future cash flow.

Our business and operations would suffer in the event of system failures or security breaches.

Despite the implementation of security measures, our computer systems, as well as those of third parties with which we have relationships, are vulnerable to damage from computer viruses, unauthorized access, natural and manmade disasters, terrorism, war and telecommunication and electrical failures. If we or a third party with which we have relationships were to experience a system failure, accident or security breach such an event could cause interruptions in our or their operations, or it could result in delays and/or material disruptions of our research and development programs. For example, the loss of trial data from completed, ongoing or planned trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach were to result in a loss of or damage to data or applications, or inappropriate disclosure of personal, confidential or proprietary information, we could incur liability and the development of our product candidates could be delayed.

The U.S. federal and various state and foreign governments have enacted or proposed requirements regarding the collection, distribution, use, security and storage of personally identifiable information and other data relating to individuals, and U.S. federal and state consumer protection laws are being applied to enforce regulations related to the online collection, use and dissemination of data. In the ordinary course of our business, we and third parties with which we have relationships collect and store sensitive data, including intellectual property, clinical trial data, proprietary business information, personal data and personally identifiable information of our clinical trial subjects and employees, consultants and contractors, in data centers and on networks. The secure processing, maintenance and transmission of this information is critical to our operations. Despite our and our collaborators’ security measures, our information technology and infrastructure may be vulnerable to attacks by hackers or internal bad actors, breaches due to employee error, technical vulnerabilities, malfeasance or other disruptions, and any such breach could compromise our or their networks and the information stored there could be accessed, publicly disclosed, lost or stolen.

Any such access, disclosure, notifications, follow-up actions related to such a security breach or other loss of information could result in legal claims or proceedings, liability under laws that protect the privacy of personal information and significant costs, including regulatory penalties, fines and legal expenses, and such an event could disrupt our operations, cause us to incur remediation costs, damage our reputation and cause a loss of confidence in us and our or such third parties’ ability to conduct clinical trials, which could adversely affect our reputation and delay our research and development programs.

We or third parties with whom we have relationships may be adversely affected by natural or manmade disasters, and our business continuity and disaster recovery plans may not adequately protect us from a serious disaster.

Natural or manmade disasters could severely disrupt our operations and have a material adverse effect on our business, results of operations, financial condition and prospects. If a natural disaster, power outage or other event occurred that prevented us from using all or a significant portion of our facilities, that damaged our infrastructure or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible for us to continue our business for a substantial period of time, and our research and development activities could be setback or delayed.

The disaster recovery and business continuity plan(s) we have in place may prove inadequate in the event of a serious disaster or similar event. We may incur substantial expenses as a result of the limited nature of our disaster recovery and business continuity plans, which could have a material adverse effect on our business, and such an event could disrupt our operations, cause us to incur remediation costs, damage our reputation and cause a loss of

confidence in us and our or third parties’ ability to conduct clinical trials, which could adversely affect our reputation and delay our research and development programs.

We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed confidential information of third parties or that our employees have wrongfully used or disclosed alleged trade secrets of their former employers.

We may now and in the future employ individuals who were previously employed at universities or other biotechnology or pharmaceutical companies, including our competitors or potential competitors. We may be subject to claims that we or our employees, consultants or independent contractors have inadvertently or otherwise used or disclosed intellectual property, including trade secrets or other proprietary information, of any of our employee’s former employer or other third parties. Litigation may be necessary to defend against these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel, which could adversely impact our business. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management and other employees and consultants.

FINRA sales practice requirements may limit a stockholder’s ability to buy and sell our common stock.

The Financial Industry Regulatory Authority (“FINRA”) has adopted rules requiring that, in recommending an investment to a customer, a broker-dealer must have reasonable grounds for believing that the investment is suitable for that customer. Prior to recommending speculative or low-priced securities to their non-institutional customers, broker-dealers must make reasonable efforts to obtain information about the customer’s financial status, tax status, investment objectives and other information. Under interpretations of these rules, FINRA has indicated its belief that there is a high probability that speculative or low-priced securities will not be suitable for at least some customers. If these FINRA requirements are applicable to us or our securities, they may make it more difficult for broker-dealers to recommend that at least some of their customers buy our common stock, which may limit the ability of our stockholders to buy and sell our common stock and could have an adverse effect on the market for and price of our common stock.

We could be subject to securities class action litigation.

In the past, securities class action litigation has often been brought against companies following a decline in the market price of their securities. This risk is especially relevant for us because biotechnology companies have experienced significant share price volatility in recent years. If we face such litigation, it could result in substantial costs and a diversion of management’s attention and resources, which could harm our business.

DIVIDEND POLICY

We currently intend to retain all available funds and any future earnings to fund the development and growth of our business and, therefore, we do not anticipate paying any cash dividends in the foreseeable future. Any future determination to declare dividends will be made at the discretion of our board of directors and will depend on our financial condition, operating results, capital requirements, contractual restrictions, general business conditions and other factors that our board of directors may deem relevant.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion and analysis of our financial condition and results of operations together with the sections titled “Selected Financial Data” and “Prospectus Summary – Summary Financial Information” in this prospectus and our financial statements and the related notes and other financial information included elsewhere in this prospectus. Some of the information contained in this discussion and analysis, including information with respect to our plans and strategy for our business, and the potential impacts of the ongoing COVID-19 pandemic, contains forward-looking statements that involve risks and uncertainties. You should review the section titled “Risk Factors” in this prospectus for a discussion of important factors that could cause actual results to differ materially from the results described below. Please also see the section entitled “Special Note Regarding Forward-Looking Statements.” On April 23, 2021, we completed a reverse triangular merger, resulting in Context Therapeutics Inc. becoming the sole holder of 100% of the membership interests in Context Therapeutics LLC, and which resulted in all of the common units, preferred units and all options, warrants or other rights to purchase common or preferred units of Context Therapeutics LLC converting into common stock, preferred stock and all options, warrants or other rights to purchase common or preferred stock of Context Therapeutics Inc. Prior to the reorganization we operated as Context Therapeutics LLC. Based on this being a transaction between entities under common control the carryover basis of accounting was used to record the assets, liabilities, and equity of Context Therapeutics LLC. Further, as a common control transaction the consolidated financial statements of the Company reflect the merger transaction as if it had occurred as of the earliest period presented herein.

Overview

We are a clinical-stage biopharmaceutical company dedicated to improving the lives of women living with cancer. Our development team is advancing a pipeline of innovative therapies with a primary focus on treating female, hormone-dependent cancer, including breast, ovarian, and endometrial (uterine) cancer. Our first program and lead product candidate, ONA-XR, builds upon a foundation of successful drug development by our management team and advisors in the field of hormone-dependent cancers. ONA-XR is a potent and selective antagonist of the progesterone receptor, which has been linked to resistance to multiple classes of cancer therapeutics, including anti-estrogen therapies, across female hormone-dependent cancers.

We were incorporated in April 2015 under the laws of the State of Delaware. Since inception, we have devoted substantially all of our resources to developing product and technology rights, conducting research and development, organizing and staffing our company, business planning and raising capital. We operate as one business segment and have incurred recurring losses, the majority of which are attributable to research and development activities, and negative cash flows from operations. We have funded our operations primarily through the sale of convertible debt and convertible preferred stock. Our net loss was $7.4 million for the nine months ended September 30, 2021. As of September 30, 2021, we had an accumulated deficit of $26.2 million.

In October 2021, we closed an initial public offering (“IPO”) on the Nasdaq Stock Market, in which we issued and sold 5,750,000 shares at a public offering price of $5.00 per share. We received gross proceeds of approximately $28.8 million as a result of the offering. In December 2021, we sold 5,000,000 shares of common stock together with warrants to purchase 5,000,000 shares of common stock in a private placement for gross proceeds of $31.3 million. We expect our existing cash and cash equivalents together with the proceeds from our IPO and proceeds from our private placement will be sufficient to fund our operations into 2024. Currently, our primary use of cash is to fund operating expenses, which consist primarily of research and development expenditures, and to a lesser extent, general and administrative expenditures. Our ability to generate product revenue sufficient to achieve profitability will depend heavily on the successful development and eventual commercialization of one or more of our current or future product candidates. We expect to continue to incur significant expenses and operating losses for the foreseeable future as we advance our product candidates through all stages of development and clinical trials and, ultimately, seek regulatory approval. In addition, if we obtain regulatory approval for any of our product candidates, we expect to incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution. Furthermore, in connection with the closing of our initial public offering, we have incurred and continue to incur additional costs associated with operating as a public company, including significant legal, accounting, investor relations and other expenses that we did not incur as a private company. Our net losses may

fluctuate significantly from quarter-to-quarter and year-to-year, depending on the timing of our clinical trials and our expenses on other research and development activities.

We expect to continue to incur net operating losses for at least the next several years, and we expect our research and development expenses, general and administrative expenses, and capital expenditures will continue to increase. We expect our expenses and capital requirements will increase significantly in connection with our ongoing activities as we:

•continue our ongoing and planned research and development of our first program and lead product candidate ONA-XR;

•continue nonclinical studies and initiate clinical trials for our anti-claudin 6 (“CLDN6”) bispecific monoclonal antibody (“BsMAb”) product and for any additional product candidates that we may pursue;

•continue to scale up external manufacturing capacity with the aim of securing sufficient quantities to meet our capacity requirements for clinical trials and potential commercialization;

•establish a sales, marketing and distribution infrastructure to commercialize any approved product candidates and related additional commercial manufacturing costs;

•develop, maintain, expand, protect and enforce our intellectual property portfolio, including patents, trade secrets and know how;

•acquire or in-license other product candidates and technologies;

•attract, hire and retain additional executive officers, clinical, scientific, quality control, and manufacturing management and administrative personnel;

•add clinical, operational, financial and management information systems and personnel, including personnel to support our product development and planned future commercialization efforts;

•expand our operations in the United States and to other geographies; and

•incur additional legal, accounting, investor relations and other expenses associated with operating as a public company.

We will need to raise substantial additional capital to support our continuing operations and pursue our growth strategy. Until such time as we can generate significant revenue from product sales, if ever, we plan to finance our operations through the sale of equity, debt financings and/or other capital sources, which may include collaborations with other companies or other strategic transactions. There are no assurances that we will be successful in obtaining an adequate level of financing as and when needed to finance our operations on terms acceptable to us, or at all. Any failure to raise capital as and when needed could have a negative impact on our financial condition and on our ability to pursue our business plans and strategies. If we are unable to secure adequate additional funding, we may have to significantly delay, scale back or discontinue the development and commercialization of one or more product candidates or delay our pursuit of potential in-licenses or acquisitions.

The COVID-19 Pandemic and its Impacts on Our Business

In March 2020, the World Health Organization declared the outbreak of COVID-19 a global pandemic. The spread of COVID-19 during 2020 and 2021 has caused worldwide economic instability and significant volatility in the financial markets. There is significant uncertainty as to the likely effects of this disease which may, among other things, materially impact the Company’s ongoing or planned clinical trials. This pandemic or outbreak could result in difficulty securing clinical trial site locations, contract research organizations (“CROs”), and/or trial monitors and other critical vendors and consultants supporting the trial. In addition, outbreaks or the perception of an outbreak near a clinical trial site location could impact the Company’s ability to enroll patients. These situations, or others associated with COVID-19, could cause delays in the Company’s clinical trial plans and could increase expected costs, all of which could have a material adverse effect on the Company’s business and its financial condition. At the

current time, the Company is unable to quantify the potential effects of this pandemic on its future consolidated financial statements.

Components of Our Results of Operations

Operating Expenses

Acquired in-process research and development expenses

Acquired in-process research and development expense consists of initial up-front payments incurred in connection with the acquisition or licensing of products or technologies that do not meet the definition of a business under Accounting Standard Codification Topic 805, Business Combinations. Acquired in-process research and development expense reflects the cash paid and/or the estimated fair value of the equity consideration given.

Research and Development Expenses

Research and development expenses have consisted primarily of costs incurred in connection with the discovery and development of our product candidates. We expense research and development costs as incurred, including:

•expenses incurred to conduct the necessary discovery-stage laboratory work, preclinical studies and clinical trials required to obtain regulatory approval;

•personnel expenses, including salaries, benefits and share-based compensation expense for our employees and consultants engaged in research and development functions;

•costs of funding research performed by third parties, including pursuant to agreements with clinical research organizations, or CROs, that conduct our clinical trials, as well as investigative sites, consultants and CROs that conduct our preclinical and clinical studies;

•expenses incurred under agreements with contract manufacturing organizations, or CMOs, including manufacturing scale-up expenses, milestone-based payments, and the cost of acquiring and manufacturing preclinical study and clinical trial materials;

•fees paid to consultants who assist with research and development activities;

•expenses related to regulatory activities, including filing fees paid to regulatory agencies; and

•allocated expenses for facility costs, including rent, utilities and maintenance.

We track outsourced development costs and other external research and development costs to specific product candidates on a program-by-program basis, fees paid to CROs, CMOs and research laboratories in connection with our preclinical development, process development, manufacturing and clinical development activities. However, we do not track our internal research and development expenses on a program-by-program basis as they primarily relate to compensation, early research and other costs which are deployed across multiple projects under development.

Research and development activities are central to our business model. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. We expect our research and development expenses to increase significantly over the next several years as we increase personnel costs, including share-based compensation, conduct our clinical trials, including later-stage clinical trials, for current and future product candidates and prepare regulatory filings for our product candidates.

General and Administrative Expenses

General and administrative expenses have consisted primarily of personnel expenses, including salaries, benefits and share-based compensation expense, for employees and consultants in executive, finance and accounting, legal, operations support, information technology and business development functions. General and administrative expense also includes corporate facility costs not otherwise included in research and development

expense, including rent, utilities and insurance, as well as legal fees related to intellectual property and corporate matters and fees for accounting and consulting services.

We expect that our general and administrative expenses will increase in the future to support our continued research and development activities, potential commercialization efforts and increased costs of operating as a public company. These increases will likely include increased costs related to the hiring of additional personnel and fees to outside consultants, legal support and accountants, among other expenses. Additionally, we anticipate increased costs associated with being a public company, including expenses related to services associated with maintaining compliance with the requirements of Nasdaq and the Securities and Exchange Commission, or SEC, insurance and investor relations costs. If any of our current or future product candidates obtain U.S. regulatory approval, we expect that we would incur significantly increased expenses associated with building a sales and marketing team.

Interest Expense

Interest expense has consisted primarily of interest expense related to our Junior Convertible Notes (“Junior Convertible Notes”) and Senior Convertible Notes (“Senior Convertible Notes,” and together with the Junior Convertible Notes, the “Convertible Promissory Notes”) outstanding at December 31, 2020 and prior to conversion in February 2021. We expect our interest expense to decrease as our Convertible Promissory Notes have been converted into Series A Stock and Series Seed convertible preferred stock (“Series Seed Stock”). All of the outstanding Convertible Promissory Notes were converted as of February 2021.

Net loss	$	(1,442,792)	$	(876,237)	(566,555)	65	%

Research and Development Expenses

Research and development expenses increased by approximately $0.3 million from $0.5 million for the three months ended September 30, 2020 to $0.7 million for the three months ended September 30, 2021. The increase was primarily due to an increase of $0.3 million in preclinical and clinical trial costs as we continued our Phase 2 trial evaluating ONA-XR that began in late 2020 and conducted pre-clinical research for the development of an anti-claudin 6 (“CLDN6”) bispecific monoclonal antibody (“BsMAb”) for gynecologic cancer therapy. Additionally, consulting services increased by approximately $0.1 million as we increased the use of third-party contractors to focus solely on developing our product candidates. The increases were offset by a decrease of $0.1 million in contracting manufacturing costs as the work on the initial manufacturing development plan was completed during the second quarter.

General and Administrative Expenses

General and administrative expenses increased by approximately $0.6 million from $0.2 million for the three months ended September 30, 2020 to $0.8 million for the three months ended September 30, 2021. The increase was mainly due to an increase of $0.5 million in salaries and related benefits as we hired an executive and issued share-based awards to members of management and the board of directors. Additionally, we incurred higher professional fees as we prepared to operate as a public company.

Interest Expense

Interest expense decreased by approximately $0.1 million from $0.1 million for the three months ended September 30, 2020 to $1,000 for the three months ended September 30, 2021, primarily due to decreased interest recognized in 2021 related to the conversion of the outstanding convertible promissory notes.

Change in Fair Value of Convertible Promissory Notes

The change in fair value of convertible promissory notes was $0.1 million for the three months ended September 30, 2020. This change was attributable to a decrease in the fair value of our common stock.

Other Income

Other income of $0.1 million for the three months ended September 30, 2021 is primarily due to the recognition of a gain on extinguishment of debt as a result of the forgiveness of our outstanding Paycheck Protection Program loan in July 2021.

Comparison of the Nine Months Ended September 30, 2021 and 2020

The following table sets forth our results of operations for the nine months ended September 30, 2021 and 2020:

Acquired In-Process Research and Development Expenses

Acquired in-process research and development expense of $3.1 million for the nine months ended September 30, 2021, reflects the fair value of consideration paid/issued under the collaboration and licensing agreement with Integral Molecular, Inc. (“Integral”) for the development of an anti-claudin 6 (“CLDN6”) bispecific monoclonal antibody (“BsMAb”) for gynecologic cancer therapy. There was no such consideration issued under collaboration arrangements in 2020.

Research and Development Expenses

Research and development expenses increased by approximately $1.5 million from $1.0 million for the nine months ended September 30, 2020 to $2.5 million for the nine months ended September 30, 2021. The increase was mainly due to an increase of $0.9 million in preclinical and clinical trial costs as we continued our Phase 2 trial

evaluating ONA-XR that began in late 2020 and conducted pre-clinical research for the development of a CLDN6 BsMAb for gynecologic cancer therapy, and an increase in contract manufacturing costs of $0.3 million for ONA-XR. Additionally, consulting services increased by approximately $0.2 million as we increased the use of third-party contractors to focus solely on developing our product candidates.

General and Administrative Expenses

General and administrative expenses increased by approximately $1.1 million from $0.8 million for the nine months ended September 30, 2020 to $1.8 million for the nine months ended September 30, 2021. The increase was mainly due to an increase of $0.6 million in salaries and related benefits as the Company hired an executive and issued share-based awards to members of management and the board of directors. Additionally, professional fees increased by $0.4 million as we prepared to operate as a public company.

Interest Expense

Interest expense decreased by approximately $0.5 million from $0.6 million for the nine months ended September 30, 2020 to $0.1 million for the nine months ended September 30, 2021 due to the conversion of all convertible promissory notes.

Change in Fair Value of Convertible Promissory Notes

The change in fair value of convertible promissory notes was $9.8 million for the nine months ended September 30, 2020 and $9,000 for the nine months ended September 30, 2021. This change was attributable to a decrease in the fair value of our common stock.

Other Income

Other income of $0.1 million for the nine months ended September 30, 2021 is primarily due to the recognition of a gain on extinguishment of debt as a result of the forgiveness of our outstanding Paycheck Protection Program loan in July 2021.

Research and Development Expenses

Research and development expenses decreased by $0.8 million from $2.4 million for the year ended December 31, 2019 to $1.6 million for the year ended December 31, 2020. The decrease was mainly due to a decrease in salaries and related benefits of $0.7 million as we reduced our full-time employees and increased third-party contractors to focus solely on developing our product candidates. Additionally, professional fees decreased by $0.3 million. These amounts were partially offset by a $0.2 million increase in preclinical and clinical trial costs as we began our Phase 2 trial in late 2020.

General and Administrative Expenses

General and administrative expenses decreased by $2.1 million from $3.0 million for the year ended December 31, 2019 to $0.9 million for the year ended December 31, 2020. The decrease was mainly due to a decrease in salaries and related benefits of $1.8 million, a decrease in professional fees of $0.2 million and a decrease in facility and other costs of $0.1 million as we reduced our full-time employees and increased third-party contractors to focus solely on developing our product candidates.

Interest Expense

Interest expense decreased by $0.4 million from $1.1 million for the year ended December 31, 2019 to $0.7 million for the year ended December 31, 2020, primarily due to decreased interest recognized in 2020 related to the conversion of our Junior Convertible Notes to Series Seed Stock that occurred in May 2020.

Change in Fair Value of Convertible Promissory Notes

The change in fair value of convertible promissory notes was $0.1 million for the year ended December 31, 2019 and $9.9 million for the year ended December 31, 2020. This change was attributable to a decrease in the fair value of our common stock.

Liquidity and Capital Resources

Overview

Since our inception, we have not recognized any revenue and have incurred operating losses and negative cash flows from our operations. We have not yet commercialized any product and we do not expect to generate revenue from sales of any products for several years, if at all. Since our inception through September 30, 2021, we have funded our operations through the sale of convertible debt and convertible preferred stock, receiving aggregate net proceeds of $21.7 million. As of September 30, 2021, we had $0.4 million in cash and cash equivalents and had an accumulated deficit of $26.2 million. In October 2021, we closed an initial public offering (“IPO”) on the Nasdaq Stock Market and received gross proceeds of approximately $28.8 million as a result of the offering. Additionally, in December 2021, sold 5,000,000 shares of our common stock together with warrants to purchase 5,000,000 shares of our common stock in a private placement and received gross proceeds of approximately $31.3 million. We expect our existing cash and cash equivalents together with the proceeds from our IPO and proceeds from our private placement will be sufficient to fund our operations into 2024. We have based these estimates on assumptions that may prove to be imprecise, and we could utilize our available capital resources sooner than we expect.

Funding Requirements

Our primary use of cash is to fund operating expenses, which consist of research and development expenditures and various general and administrative expenses. Cash used to fund operating expenses is impacted by the timing of when we pay these expenses, as reflected in the change in our outstanding accounts payable, accrued expenses and prepaid expenses.

Because of the numerous risks and uncertainties associated with research, development and commercialization of pharmaceutical products, we are unable to estimate the exact amount of our operating capital requirements. Our future funding requirements will depend on many factors, including, but not limited to:

•the scope, timing, progress and results of discovery, preclinical development, laboratory testing and clinical trials for our product candidates;

•the costs of manufacturing our product candidates for clinical trials and in preparation for regulatory approval and commercialization;

•the extent to which we enter into collaborations or other arrangements with additional third parties in order to further develop our product candidates;

•the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims;

•the costs and fees associated with the discovery, acquisition or in-license of additional product candidates or technologies;

•expenses needed to attract and retain skilled personnel;

•costs associated with being a public company;

•the costs required to scale up our clinical, regulatory and manufacturing capabilities;

•the costs of future commercialization activities, if any, including establishing sales, marketing, manufacturing and distribution capabilities, for any of our product candidates for which we receive regulatory approval; and

•revenue, if any, received from commercial sales of our product candidates, should any of our product candidates receive regulatory approval.

We will need additional funds to meet our operational needs and capital requirements for clinical trials, other research and development expenditures, and general and administrative expenses. We currently have no credit facility or committed sources of capital.

Until such time, if ever, as we can generate substantial product revenue, we expect to finance our operations through a combination of equity offerings, debt financings, collaborations, strategic alliances and/or marketing, distribution or licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a common stockholder. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making acquisitions or capital expenditures or declaring dividends. If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates, or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings or other arrangements when needed, we may be required to delay, limit, reduce or terminate our research, product development or future commercialization efforts, or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Comparison of the Nine Months Ended September 30, 2021 and 2020

Operating Activities

During the nine months ended September 30, 2021, we used $3.8 million of cash in operating activities. Cash used in operating activities reflected our net loss of $7.4 million, a gain of $0.1 million from the extinguishment of debt and an increase in our operating assets and liabilities of $0.2 million. This was offset by non-cash in-process research and development charges of $3.1 million, the non-cash fair value measurement of warrants for services of $0.4 million and non-cash interest expense and share-based compensation of $0.4 million. The primary uses of cash were to fund our operations related to the development of our product candidates.

During the nine months ended September 30, 2020, we used $0.9 million of cash in operating activities. Cash used in operating activities reflected the noncash change in fair value of convertible promissory notes of $9.8 million, offset by our net income of $7.4 million, noncash interest expense of $0.6 million, share-based compensation of $0.2 million and a $0.7 million net decrease in our operating assets and liabilities. The primary use of cash was to fund our operations related to the development of our product candidates.

Investing Activities

During the nine months ended September 30, 2021, cash used in investing activities was attributable to the initial upfront license fee of $0.3 million related to the Company’s acquired in-process research and development.

We did not have cash flows from investing activities during the nine months ended September 30, 2020.

Financing Activities

During the nine months ended September 30, 2021, financing activities provided $4.2 million, primarily consisting of net proceeds of $5.0 million from the sale of Series A Stock and warrants for common stock. This was offset by the payment of $0.8 million of offering costs related to our IPO.

During the nine months ended September 30, 2020, financing activities provided $0.8 million, consisting of $0.6 million of proceeds from the sale of Series A Stock and warrants for common stock, $25,000 from the issuance of convertible bridge notes, $50,000 from the sale of Series Seed Stock and $0.1 million of proceeds from the Paycheck Protection Program loan.

Comparison of the Years Ended December 31, 2020 and 2019

Operating Activities

During the year ended December 31, 2020, we used $1.0 million of cash in operating activities. Cash used in operating activities reflected the noncash change in fair value of convertible promissory notes of $9.9 million, offset by our net income of $6.6 million, noncash interest expense of $0.7 million, share-based compensation of $0.2 million and a $1.3 million net decrease in our operating assets and liabilities. The primary use of cash was to fund our operations related to the development of our product candidates.

During the year ended December 31, 2019, we used $2.8 million of cash in operating activities. Cash used in operating activities reflected our net loss of $6.4 million and the noncash change in fair value of convertible promissory notes of $0.1 million, offset by noncash interest expense of $1.1 million, noncash expense related to convertible promissory notes issued in lieu of severance payments of $1.2 million, share-based compensation expense of $0.8 million, and a decrease in our operating assets and liabilities of $0.6 million.

Investing Activities

We did not have cash flows from investing activities for either period presented.

Financing Activities

During the year ended December 31, 2020, financing activities provided $1.1 million, consisting of $1.0 million of proceeds from the sale of Series A Stock and warrants for common stock, $25,000 from the issuance of convertible bridge notes, $50,000 from the sale of Series Seed Stock and $0.1 million of proceeds from the Paycheck Protection Program loan.

During the year ended December 31, 2019, financing activities provided $2.0 million from the issuance of convertible promissory notes and convertible bridge notes.

Off-Balance Sheet Arrangements

During the periods presented, we did not have, nor do we currently have, any relationships with unconsolidated entities or financial partnerships, including entities sometimes referred to as structured finance or special purpose entities that were established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. We do not engage in off-balance sheet financing arrangements. In addition, we do not engage in trading activities involving non-exchange traded contracts. We therefore believe that we are not materially exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in these relationships.

Critical Accounting Policies

This management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, and expenses and the disclosure of contingent assets and liabilities in our consolidated financial statements. On an ongoing basis, we evaluate our estimates and judgments, including those related to prepaid/accrued research and development expenses, share-based compensation and fair value of convertible promissory notes. We base our estimates on historical experience, known trends and events, and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in Note 3 to our audited consolidated financial statements included elsewhere in this prospectus, we believe the following accounting policies are the most critical to the judgments and estimates used in the preparation of our consolidated financial statements.

Internal Control Over Financial Reporting

Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with U.S. GAAP. Under standards established by the Public Company Accounting Oversight Board, or PCAOB, a deficiency in internal control over financial reporting exists when the design or operation of a control does not allow management or personnel, in the normal course of performing their assigned functions, to prevent or detect misstatements on a timely basis. The PCAOB defines a material weakness as a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of annual or interim financial statements will not be prevented, or detected and corrected, on a timely basis.

During the preparation of our consolidated financial statements for the years ended December 31, 2019 and 2020, we and our independent registered public accounting firm identified a material weakness related to the lack of an appropriate review of the internally prepared financial statements which resulted in the Company’s failure to timely detect and correct certain misstatements within the consolidated financial statements. Such misstatements have been corrected in the accompanying consolidated financial statements for the years ended December 31, 2019 and 2020. We also identified a material weakness as it relates to a lack of adequate segregation of accounting functions.

We are in the process of implementing measures designed to improve our internal control over financial reporting to remediate these material weaknesses. Our plan to remediate the material weaknesses in our internal control over financial reporting includes utilizing a portion of the working capital from our initial public offering to increase staffing within our accounting infrastructure sufficient to facilitate proper segregation of accounting functions and to enable appropriate review of our internally prepared consolidated financial statements. In addition, we plan to retain outside consultants, expert in, and specializing in technical accounting and SEC reporting for public company registrants.

Research and Development Expenses

Research and development expenses consist primarily of costs incurred in connection with the development of our product candidates. We expense research and development costs as incurred.

We accrue an expense for preclinical studies and clinical trial activities performed by our vendors based upon estimates of the proportion of work completed. We determine the estimates by reviewing contracts, vendor agreements and purchase orders, and through discussions with our internal clinical personnel and external service providers as to the progress or stage of completion of trials or services and the agreed-upon fee to be paid for such services. However, actual costs and timing of clinical trials are highly uncertain, subject to risks and may change depending upon a number of factors, including our clinical development plan.

We make estimates of our prepaid/accrued expenses as of each balance sheet date in our consolidated financial statements based upon facts and circumstances known at that time. If the actual timing of the performance of services or the level of effort varies from the estimate, we will adjust the accrual accordingly. Nonrefundable advance payments for goods and services, including fees for clinical trial expenses, process development or manufacturing and distribution of clinical supplies that will be used in future research and development activities, are deferred and recognized as expense in the period that the related goods are consumed, or services are performed.

Share-Based Compensation

We measure compensation expense for all share-based awards based on the estimated fair value of the share-based awards on the grant date. We use the Black-Scholes option pricing model to value our share-based awards. We recognize compensation expense on a straight-line basis over the requisite service period, which is generally the vesting period of the award. We have not issued awards for which vesting is subject to market or performance conditions.

The Black-Scholes option-pricing model requires the use of subjective assumptions that include the expected stock price volatility and the fair value of the underlying common stock on the date of grant. See Note 7 to our audited consolidated financial statements and our unaudited condensed consolidated financial statements included elsewhere in this prospectus for information concerning certain of the specific assumptions we used in applying the Black-Scholes option pricing model to determine the estimated fair value of our awards granted.

Recent Accounting Pronouncements

See Note 3 to our audited consolidated financial statements and unaudited condensed consolidated financial statements found elsewhere in this prospectus for a description of recent accounting pronouncements applicable to our consolidated financial statements.

Qualitative and Quantitative Disclosures About Market Risk

We are exposed to market risk related to changes in interest rates. As of September 30, 2021, we had cash and cash equivalents of $0.4 million consisting of bank deposits and a commercial money market account. Due to the short-term duration of our cash equivalents, an immediate 10% change in interest rates would not have a material effect on the fair market value.

Inflation generally affects us by increasing our labor and clinical trial costs. We do not believe inflation had a material effect on our business, financial condition or results of operations during the years ended December 31, 2020 and 2019.

Emerging Growth Company and Smaller Reporting Company Status

In April 2012, the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, was enacted. Section 107 of the JOBS Act provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended, for complying with new or revised accounting standards. Thus, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to avail ourselves of this exemption from complying with new or revised accounting standards and, therefore, will not be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies. As a result, our financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

We are in the process of evaluating the benefits of relying on other exemptions and reduced reporting requirements under the JOBS Act, including without limitation, exemption to the requirements for providing an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act. We will remain an emerging growth company until the earlier to occur of (a) the last day of the fiscal year (i) following October 19, 2026, (ii) in which we have total annual gross revenues of at least $1.07 billion or (iii) in which we are deemed to be a “large accelerated filer” under the rules of the SEC, which means that we have been required to file annual and quarterly reports under the Exchange Act for a period of at least 12 months and have filed at least one annual report pursuant to the Exchange Act and either (a) the market value of our common stock that is held by non-affiliates exceeds $700.0 million as of the prior June 30th, or (b) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period.

We are also a “smaller reporting company,” meaning that the market value of our stock held by non-affiliates is less than $700.0 million and our annual revenue is less than $100.0 million during the most recently completed fiscal year. We will continue to be a smaller reporting company until either (i) the market value of our stock held by non-affiliates is less than $250.0 million or (ii) our annual revenue is less than $100.0 million during the most recently completed fiscal year and the market value of our stock held by non-affiliates is less than $700.0 million. If we are a smaller reporting company at the time we cease to be an emerging growth company, we may continue to rely on exemptions from certain disclosure requirements that are available to smaller reporting companies. Specifically, as a smaller reporting company we may choose to present only the two most recent fiscal years of audited financial statements in our Annual Report on Form 10-K and, similar to emerging growth companies, smaller reporting companies have reduced disclosure obligations regarding executive compensation.

BUSINESS

Overview

We are a clinical-stage biopharmaceutical company dedicated to improving the lives of women living with cancer.

Profound advancements in oncology drug development have expanded the treatment options available to women with cancer, yet therapeutic resistance and relapse continue to limit the efficacy and duration of such treatments. Collectively, our founders and management team have decades of experience identifying and characterizing the mechanisms that drive cancer initiation and subsequent relapse in women with cancer and who have been associated with the development of products such as Kisqali (ribociclib), Arimidex (anastrozole), and Afinitor (everolimus) to treat such cancers.

Our development team is advancing a pipeline of innovative therapies with a primary focus on treating female cancers. Our first program and lead product candidate, onapristone extended release (“ONA-XR”), builds upon a foundation of successful drug development by our management team and advisors in the field of female hormone-dependent cancers. ONA-XR is a selective and potentially potent antagonist of the progesterone receptor (PR), a receptor that is activated by the hormone progesterone and that has been linked to resistance to multiple classes of cancer therapeutics, including anti-estrogen therapies, that are prescribed to treat female hormone-dependent cancers. In 2020, we initiated a Phase 2 investigator-sponsored trial in collaboration with Thomas Jefferson University to evaluate ONA-XR in combination with Arimidex (anastrozole) in PR+ endometrial cancer and preliminary data is expected in the second half of 2022. Also, in 2020 we initiated a Phase 0 trial of ONA-XR in a window of opportunity study in primary breast cancer, and we reported preliminary data at the San Antonio Breast Cancer Symposium in December 2021. The window of opportunity study is a three week study in women with primary breast cancer and subsequent lumpectomy to evaluate the direct effects of ONA-XR on the cancer signaling pathways and the tumor microenvironment. In 2021, a Phase 1b/2 investigator-sponsored trial was initiated in collaboration with Memorial Sloan Kettering Cancer Center to evaluate ONA-XR in combination with Ibrance (palbociclib) and Femara (leterozole) in first line metastatic breast cancer patients with biochemically recurrent disease, defined as circulating tumor DNA (ctDNA) positive. This is potentially a new clinical opportunity for the estimated 20% of 1L patients who are at high risk of early disease progression on Ibrance and Femara therapy. In 2021, we completed the first stage of our Phase 2 trial evaluating ONA-XR in recurrent granulosa cell tumors (GCT) of the ovary and in July 2021 we initiated the second stage of this trial evaluating ONA-XR in combination with the antiestrogen, anastrozole. Also in 2021, a Phase 2 investigator-sponsored trial was initiated in collaboration with Wisconsin Oncology Network to evaluate ONA-XR in combination with Faslodex (fulvestrant) in second or third line metastatic breast cancer. This trial is intended to establish ONA-XR plus Faslodex drug synergy after treatment failure of CDK4/6 inhibitor and/or PIK3α inhibitors. We expect to report preliminary data from one of these trials in the first half of 2022. In 2021, we also initiated a sub-study of our Phase 2 trial in 2L/3L metastatic breast cancer, which evaluates the uptake of radiolabeled progesterone (F-FFNP) via PET imaging in breast tumors, with preliminary data expected to come in the second half of 2022. Our second program, CLDN6xCD3 bsAb, is an anti-CD3 x anti-Claudin 6 (CLDN6) antigen bispecific monoclonal antibody (bsAbs) that is intended to redirect T-cell-mediated lysis toward malignant cells expressing CLDN6. CLDN6 is a tight junction membrane protein target expressed in multiple cancers, including ovarian and endometrial tumors, and absent from healthy adult tissues. We expect to enter IND-enabling studies for CLDN6xCD3 bsAb in 2022. Beyond these two product candidates, we have a discovery-stage program evaluating antagonists of Sigma1 for breast and prostate cancer. We believe our team and capabilities uniquely position us to be a leader in developing novel therapies to address female hormone-dependent cancers.

of bispecific antibodies and to certain patents related to Sigma1. Our product candidates are shown in the table below:

Our Product Pipeline and Development

PR antagonist program: ONA-XR

Currently, there are no approved therapies that selectively target progesterone receptor positive (PR+) cancers. Preclinical and clinical data suggest that onapristone extended release (ONA-XR) has anticancer activity by inhibiting PR binding to chromatin, downregulating cancer stem cell mobilization and blocking immune evasion. ONA-XR is currently being evaluated in three Phase 2 trials, one Phase 1b/2 trial and one Phase 0 biomarker pharmacodynamic trial in women with primary or metastatic breast, ovarian, and endometrial cancers. These trials are intended to establish safety, pharmacokinetics, pharmacodynamics, and anti-tumor activity at the recommended Phase 2 dose of ONA-XR to guide potential advancement in Phase 3 development in 2023.

To help inform which patients may be most suitable for treatment with ONA-XR, we are evaluating multiple biomarker assays, including tools to monitor activated progesterone receptor as well as a PR gene activation signature that measures PR signaling activity, both of which are being utilized in our ongoing clinical trials and may be used for patient selection in future clinical trials. We expect to report preliminary data from at least one Phase 2 trial in the first half of 2021 and from the other trials in the second half of 2022.

CLDN6xCD3 bispecific antibody program

Our second program, CLDN6xCD3 bsAb, is an anti-CD3 x anti-Claudin 6 (CLDN6xCD3) antigen bispecific monoclonal antibody (bsAbs) that is intended to redirect T-cell-mediated lysis toward malignant cells expressing CLDN6. CLDN6 is a tight junction membrane protein target expressed in multiple hormone-dependent cancers, including ovarian and endometrial tumors, and absent from healthy adult tissues. The structural complexity of CLDN6 and its similarity to proteins expressed on healthy tissue, particularly Claudin 4 and Claudin 9 (CLDN9), have limited its exploitation for targeted oncology therapies. Several global pharmaceutical companies are developing anti-CLDN6 antibodies, but due to significant antibody selectivity challenges, to our knowledge, there are no selective inhibitors of CLDN6 in clinical development. We expect to enter IND-enabling studies for CLDN6xCD3 bsAb in 2022.

Other preclinical programs

Our Management Team

We have assembled a management team to develop novel products to treat female hormone-dependent cancers. Members of our management team have experience leading organizations that have advanced multiple oncology therapeutics from early-stage research to clinical trials, and ultimately to regulatory approval and commercialization. Our team’s select accomplishments include:

•Our Chief Financial Officer previously served as Chief Financial Officer of Millendo Therapeutics, a publicly-traded biopharmaceutical company. Prior to Millendo, our CFO served as Director of Technical Accounting at PAREXEL International and began her career as an auditor at Ernst & Young.

•Our Chief Legal Officer previous severed as Vice President, Deputy General Counsel and Assistant Corporate Secretary of OptiNose, a publicly-traded specialty pharmaceutical company. Prior to OptiNose, he served as Associate General Counsel of Teva Pharmaceuticals, a global pharmaceuticals company, from 2010 until 2017.

•Our management team has been involved in several multimillion-dollar strategic transactions, including as part of the leadership teams at Celgene, Novartis, and Ception Therapeutics.

We are supported by our advisors who are leading experts in hormone-dependent cancer and anti-estrogen resistance, including Dr. Carol Lange, Dr. Larry Norton, and Dr. Felix Kim, a co-founder of Context. Our arrangements with these individuals do not entitle us to any of their existing or future intellectual property derived from their independent research or research with other third parties beyond what has previously been licensed to us.

Strategy

Our goal is to develop and commercialize innovative and differentiated oncology products that address significant unmet medical needs in the field of female cancer, with a primary focus on the hormone-dependent subcategory. The key components of our strategy to achieve this goal include:

•Leveraging the insights, experience, and networks of our management team and advisors. Our management team and advisors have extensive experience identifying, developing, and commercializing innovative cancer therapeutics aimed at novel targets, including Kisqali, Arimidex, and Afinitor. We are using this broad oncology experience together with our internal search and development capabilities to build a diverse pipeline of therapies targeting multiple cancer resistance mechanisms. For example, our first program and lead product candidate, ONA-XR, while acquired from Arno Therapeutics, builds on academic work originally conducted by the laboratory of our scientific advisor, Dr. Carol Lange.

•Focusing on product candidates that can be first or second in market based on current competition. We believe that being first or second in market provides a unique advantage that later competitors may not be able to overcome. Based on the current competitors that are developing similar product candidates, we believe that we have the opportunity to be the first anti-progestin approved for PR+ cancer and one of the early market participants with our CLDN6xCD3 bsAb.

•Completing clinical development and obtaining regulatory approval for ONA-XR for the treatment of breast, ovarian, and endometrial cancer. The PR signaling pathway has been implicated in resistance to anti-estrogen therapies in female hormone-dependent cancers, including breast, ovarian, and endometrial cancer. Our clinical development effort for ONA-XR, a selective and potentially potent small molecule antagonist of PR, will initially focus on indications where there is evidence suggesting PR-mediated signaling contributes to resistance and disease progression. In 2020, a Phase 2 investigator-sponsored trial was initiated in collaboration with Thomas Jefferson University to evaluate ONA-XR in combination with Arimidex (anastrozole) in PR+ endometrial cancer and preliminary data is expected in the second half of 2022. Also, in 2020, we initiated a Phase 0 trial of ONA-XR in a window of opportunity study in primary breast cancer, and we reported preliminary data at the San Antonio Breast Cancer Symposium in December 2021. In 2021, a Phase 1b/2 investigator-sponsored trial was initiated in collaboration with Memorial Sloan Kettering Cancer Center to evaluate ONA-XR in combination with Ibrance (palbociclib) and Femara (leterozole) in first line metastatic breast cancer patients with biochemically recurrent disease, defined as circulating tumor DNA (ctDNA) positive. This is potentially a new clinical opportunity for the estimated 20% of 1L patients who are at high risk of early disease progression on Ibrance and Femara therapy. In 2021, we completed the first stage of our Phase 2 trial evaluating ONA-XR in recurrent granulosa cell tumors (GCT) of the ovary and in July 2021 we initiated the second stage of this trial evaluating ONA-XR in combination with the antiestrogen, anastrozole. Also in 2021, a Phase 2 investigator-sponsored trial was initiated in collaboration with Wisconsin Oncology Network to evaluate ONA-XR in combination with Faslodex (fulvestrant) in 2L/3L metastatic breast cancer. This trial is intended to establish ONA-XR plus Faslodex drug synergy after treatment failure of CDK4/6 inhibitor and/or PIK3α inhibitors. We expect to report preliminary data from one of these trials in the first half of 2022. In 2021, we also initiated a sub-study of our Phase 2 trial in 2L/3L metastatic breast cancer, which evaluates radiolabeled progesterone uptake in breast tumors, with preliminary data expected to come in the second half of 2022.

•Advancing our second program, CLDN6xCD3 bsAb, as rapidly as reasonably possible through preclinical and clinical development. Our second program, CLDN6xCD3 bsAb, is an anti-CD3 x anti-Claudin 6 (CLDN6xCD3) antigen bispecific monoclonal antibody (bsAbs) that is intended to redirect T-cell-mediated lysis toward malignant cells expressing CLDN6. CLDN6 is a membrane protein target expressed in multiple hormone-dependent cancers, including ovarian and endometrial, and absent from healthy adult tissues. We expect to enter IND-enabling studies for CLDN6xCD3 bsAb in 2022.

•Developing our other drug candidates. In addition to our product candidates, we are leveraging our knowledge in hormone-dependent cancer to pursue discovery stage research programs, including Sigma1. Sigma1 is a cellular protein that regulates homeostasis and has been shown to play a role in breast and

prostate cancer. The Sigma1 discovery research program is currently in lead optimization and has undergone in vivo studies.

•Evaluating opportunities to accelerate development timelines and enhance the commercial potential of our programs in collaboration with third parties, including through the potential out-licensing of our product candidates. We have established collaborations and intend to continue evaluating opportunities to work with partners that meaningfully enhance our capabilities with respect to the development and commercialization of our product candidates, which may entail the potential out-licensing of the development and commercialization of our product candidates to larger pharmaceutical organizations, including our lead product candidate ONA-XR. For example, we entered into a manufacturing and development agreement with Tyligand Bioscience (Shanghai) Limited for ONA-XR that is intended to enhance our ability to meet drug manufacturing demands and expand our clinical trial footprint into Greater China. It is also possible that similar arrangements for ONA-XR could be sought for other geographic footprints. In addition, we intend to commercialize our product candidates in key markets either alone or with partners in order to maximize the worldwide commercial potential of our programs.

•In-licensing or acquiring additional drug candidates to build a fully integrated company focused on female hormone-dependent cancers. We believe that accessing external innovation and expertise is important to our success and plan to leverage our leadership team’s prior business development experience as we evaluate potential in-licensing and acquisition opportunities to further expand our portfolio. For example, CLDN6xCD3 bsAb was licensed from Integral Molecular, Inc. (“Integral”), a company where our management and advisors have long-standing relationships. We aim to be the partner of choice for academic groups and companies in the field of female cancers.

Our focus on female hormone-dependent cancer

Up to 70% of women with breast, ovarian, and endometrial cancer have hormone-dependent cancer. The hormones estrogen and progesterone drive cancer progression in those patients, but anti-estrogens are the only antihormonal therapy that is FDA approved and available to clinicians. Therefore, treatment of those patients to date has consisted of anti-estrogens alone or in combination with drugs that enhance the antitumor activity of anti-estrogens, including inhibitors of CDK4/6 or PI3Kα. Given the broad use of anti-estrogens, anti-estrogen resistance is now a major clinical challenge. Treatment options for anti-estrogen resistance are limited, provide modest therapeutic benefit, and are associated with side effects.

Estrogen and progesterone are master regulators of normal female sex organ development and function, acting via estrogen receptors (“ER”) and progesterone receptors (“PR”). Mechanistically, published data suggest that in hormone-dependent cancers, ER and PR are often hyperactive, constantly pushing breast, ovary, and endometrial tissues to grow, divide, and metastasize. One such strategy to block this hormone-mediated growth is to administer anti-estrogen therapy (fulvestrant, letrozole, anastrozole, or tamoxifen), which may be used in combination with inhibitors of CDK4/6 or PI3Kα to enhance anti-estrogen mediated effects. However, the cancer cells respond to this selective pressure of ER inhibition by further activating progesterone signaling as a compensatory mechanism, along with other resistance mechanisms that can further activate PR, including ER ligand binding mutations (ESR1), growth factor signaling, and enrichment of cancer stem cells. Over time, it is believed that all patients become resistant to anti-estrogens due to direct or indirect compensatory signaling mediated by the PR and other factors. These findings suggest that progesterone receptor and proteins that regulate PR could represent promising drug targets to address anti-estrogen resistance.

Overview of antiestrogen resistance mechanisms

We are building a portfolio of novel agents targeting multiple anti-estrogen resistance mechanisms by leveraging our specialized expertise in hormone-dependent cancers.

PR antagonist program: ONA-XR

Published data suggest that the PR signaling pathway is implicated in resistance to anti-estrogen therapies in female hormone-dependent cancer, including breast, ovarian, and endometrial cancer. Our clinical development effort for ONA-XR, a selective and potentially potent small molecule antagonist of PR, will initially focus on indications where there is evidence suggesting PR-mediated signaling contributes to resistance and disease progression. In 2020, a Phase 2 investigator-sponsored trial was initiated in collaboration with Thomas Jefferson University to evaluate ONA-XR in combination with Arimidex (anastrozole) in PR+ endometrial cancer and preliminary data is expected in the second half of 2022. Also, in 2020 we initiated a Phase 0 trial of ONA-XR in a window of opportunity study in primary breast cancer, and we reported preliminary data at the San Antonio Breast Cancer Symposium in December 2021. In 2021, a Phase 1b/2 investigator-sponsored trial was initiated in collaboration with Memorial Sloan Kettering Cancer Center to evaluate ONA-XR in combination with Ibrance (palbociclib) and Femara (leterozole) in first line metastatic breast cancer patients with biochemically recurrent disease, defined as circulating tumor DNA (ctDNA) positive. This is potentially a new clinical opportunity for the estimated 20% of 1L patients who are at high risk of early disease progression on Ibrance and Femara therapy. In 2021, we completed the first stage of our Phase 2 trial evaluating ONA-XR in recurrent granulosa cell tumors (GCT) of the ovary and in July 2021 we initiated the second stage of this trial evaluating ONA-XR in combination with the antiestrogen, anastrozole. Also in 2021, a Phase 2 investigator-sponsored trial was initiated in collaboration with Wisconsin Oncology Network to evaluate ONA-XR in combination with Faslodex (fulvestrant) in 2L/3L metastatic breast cancer. This trial is intended to establish ONA-XR plus Faslodex drug synergy after treatment failure of CDK4/6 inhibitor and/or PIK3α inhibitors. We expect to report preliminary data from one of these trials in the first half of 2022. In 2021, we also initiated a sub-study of our Phase 2 trial in 2L/3L metastatic breast cancer, which evaluates the radiolabeled progresterone uptake in breast tumors, with preliminary data expected to come in the second half of 2022.

Progesterone receptor background

Progesterone receptor (PR) is a member of the nuclear hormone receptor family of ligand-dependent transcription factors that is expressed primarily in female reproductive tissues. In response to the endogenous steroid hormone, progesterone, PR regulates the expression of gene networks to control development, differentiation, and proliferation of target tissues and the pathological processes in endocrine-based cancers. Anti-progestins are a class

of nuclear receptor ligands that act to antagonize PR by binding to the progesterone binding site within the PR-ligand binding domain.

Recently, the role of progesterone in carcinogenesis has gained further clarity. Mechanistically, published data suggest that progesterone promotes oncogenic progression and maintenance of stem cells, creating a reservoir of pre-malignant cells to seed metastasis. Initial evidence for this tumorigenic role is derived from longitudinal studies of the use of hormone replacement therapy in menopausal women. As shown in the figure below, these studies determined that supplemental estrogen was associated with a 23% decrease in cancer risk, whereas supplemental progesterone was associated with a 25% increase in cancer risk. The results demonstrated that women who were consistently exposed to progesterone had a higher risk of developing breast cancer than those who did not. This finding was confirmed by published data wherein mice treated with progesterone exhibited enhanced breast tumor growth whereas progesterone receptor inhibition via genetic knockdown conversely inhibited tumor growth.

As shown in the figure above, PR can be activated by ligand (progesterone) or ligand-independent (growth factor-mediated) mechanisms. Consistent with other steroid hormone receptor family members, PR is heavily post-translationally modified and thus acts as a molecular sensor for abnormally elevated or active signaling pathways. Little overlap exists between PR transcriptomes assayed in normal relative to neoplastic cells. In cancer cells, post-translational modifications (namely, phosphorylation and SUMOylation) via members of the growth factor signaling cascade create unique PR species whose altered behavior as ligand-dependent transcription factors is predicted to impact tumor initiation and progression. Due to the breadth of post-translational modifications of PR, there is limited selective mutational pressure to modify PR itself - thus, PR mutations are rare. However, when present, the PR mutations have a profound impact on PR activity and tumorigenesis.

The progesterone receptor as a mechanism of resistance

Recently, progesterone receptor has emerged as anti-estrogen resistance mechanism. Long term exposure of cancer cells to anti-estrogens results in a complex resistance profile that limits the utility of standard of care anti-estrogen and cyclin-dependent kinase 4/6 (CDK4/6) inhibitors. Mechanisms of resistance include mutations in the estrogen receptor (ESR1) estrogen binding domain and ER pathway signaling (e.g., MAPK, PI3Kα/mTOR proteins and associated signaling pathways). The prevalence of resistance mutations is associated with PR enrichment and activity. Based on our preclinical data and recent published data, we believe therapeutic inhibition of PR with either ONA-XR alone or in combination with anti-estrogens and/or CDK4/6 inhibitors may result in the impaired growth or death of resistant cells.

Limitations of other PR antagonists

Anti-progestins, the therapeutic inhibitors of PR, were first developed as oral contraceptives to block the maturation of the endometrium and subsequent ovulation. The first commercially available anti-progestin, Korlym (mifepristone), is a steroid derivative that acts both as a competitive progesterone receptor (PR) antagonist and as a partial PR agonist, depending on the physiological milieu. Mifepristone is approved for controlling hyperglycemia secondary to hypercortisolism in adult Cushing’s syndrome associated with Type 2 diabetes. Mifepristone was also clinically evaluated in breast and ovarian carcinomas, and while showing evidence of efficacy in clinical studies, mifepristone was also associated with off-target glucocorticoid receptor (GR) modulation leading to cortisolemia and rare cases of cholestasis. In order to optimize PR antagonism while minimizing off-target activities, additional anti-progestins—including ulipristal, telapristone, lonaprisan and onapristone—were developed and evaluated in gynecological cancer.

Unique Properties of Onapristone – Stereochemical Basis

ONA-XR differentiation

Onapristone is a competitive PR antagonist that has no intrinsic activity for activating the receptor. As such, onapristone is also termed a “full” PR antagonist (inhibitor). Based on published data, all other anti-progestins that have reached the clinic demonstrate partial PR agonism. This differentiation may have a structural basis. It is well established that high energy, conformationally complex chemicals have improved selectivity and target affinity relative to low energy, flat counterparts. As shown above, all other anti-progestins have a roughly planar ring, low energy, A thru D conformation. In contrast, onapristone shows an inversion of stereochemistry at the C-13 methyl group that results in a high energy, chair conformation. This structural property is unique among clinically evaluated anti-progestins and may be important for onapristone’s full PR antagonist properties, as shown below.

Classic in vitro models have provided limited benefit in determining PR agonist versus antagonist properties. As the cost of gene expression profiling has decreased considerably over the last decade, it is now feasible to run comparative studies to determine how compounds are affecting the expression, positively or negatively, of target genes. Afhuppe et al (2009) conducted the first such study comparing anti-progestins in a gene array panel. T47D breast cancer cells (ER+, PR+) were grown in 2D, stimulated with estrogen (estradiol), and treated with anti-

progestins. An Affymetrix® gene chip analysis of the cells was then conducted to determine transcriptional activity on the level of target genes. Onapristone demonstrated the purest PR antagonist activity as indicated downregulation (green blocks) of almost all PR target genes analyzed, whereas mifepristone had a transcriptional profile closer to R5020, which is pure progesterone.

Anti-progestin clinical trial data

In subjects with breast cancer, clinical trials with mifepristone, lonapristone and onapristone demonstrated partial responses. Onapristone clinical efficacy in breast cancer was studied in two Phase 1-2 clinical studies treating hormone therapy-naïve and tamoxifen-resistant metastatic breast cancer, while the safety component of a third Phase 1-2 study has been reported by Cottu et al. (2018). The earlier onapristone trials in breast cancer dosed orally with a simple solid dosage form (an “immediate release” or “IR” form; onapristone IR; ONA-IR), ONA-IR 100mg once per day (QD), for periods exceeding 12 months. The third breast cancer study used the extended release form, ONA-XR, dosed at 50mg twice per day (BID). Robertson et al (1999) reported a 67% clinical benefit rate (CBR), defined as tumor shrinkage or tumor growth stabilization lasting for more than 6 months, while Jonat et al (2002) reported a 49% CBR. Both studies, therefore, indicated that onapristone could have a clinically meaningful impact on treatment of hormone-dependent breast cancer. Clinical development of ONA-IR for use in reproductive medicine and benign gynecological conditions was discontinued by the original sponsor (Schering AG), possibly due to concerns around drug-induced liver injury.

The extensive use of anti-estrogens, together with efficacy limits with earlier anti-progestins, has led to renewed interest in anti-progestins as therapies for breast and gynecologic cancer, as well as for uterine fibroids and endometriosis. Compared to earlier anti-progestin clinical trials, we believe we have a better tolerated formulation of onapristone (ONA-XR) and we will be able to better identify those patients who are most likely to benefit from anti-progestin therapy through the incorporation of biomarkers in our trials.

Our current opportunities for ONA-XR

Within the G7 (EU5, Japan, US) countries, it is estimated that there are over 355,000 patients living with metastatic breast, ovarian, or endometrial cancer. Up to 70% of these patients are expected to be progesterone receptor positive and would potentially be eligible for treatment with ONA-XR.

Resistance to anti-estrogen therapy in breast cancer

We have chosen PR antagonism in breast cancer as our initial therapeutic focus due to the well-documented biology of PR signaling as a mechanism of resistance to anti-estrogen therapy in patients with hormone-dependent breast cancer. Hormone-dependent breast cancer cells express estrogen (ER) and/or progesterone receptors (PR) that allow the cells to grow in the presence of the hormones estrogen and/or progesterone. Published data suggests that PR signaling is predominantly required for breast cancer cell renewal (i.e., stemness) and metastatic spread, whereas ER is predominantly required for breast cancer cell proliferation. By combining anti-progestin and anti-estrogen therapy, we have shown preclinically that breast cancer cell growth, renewal, and spread can be mitigated. Based on these data, we believe that ONA-XR, in combination with current standard-of-care anti-estrogens, has the potential to significantly improve clinical outcomes.

Breast cancer overview

Breast cancer is the most frequent cancer among women, impacting 2.1 million women globally each year, and causing the greatest number of cancer-related deaths among women. In 2018, it is estimated that 627,000 women died from breast cancer worldwide — that is approximately 15% of all cancer deaths among women according to the World Health Organization. According to the American Cancer Society, the prevalence of women in the United States living with adjuvant, first line metastic, or second/third line metastatic breast cancer are an estimated 250,000, 75,000, and 35,000 respectively.

Breast cancer treatment is primarily determined by the presence or absence of three proteins: estrogen receptor (ER), progesterone receptor (PR), and HER2. The presentation of these proteins determines the subtype of breast cancer, which helps determine the optimal form of treatment for the patient. Patients who are ER+,PR+,HER2- are considered to be hormone receptor positive (i.e., hormone-dependent) and represent about 70% of breast cancers. HER2+ patients and triple negative patients (ER-,PR-,HER2-) represent the remaining 30% of breast cancers.

Estrogen-deprivation (anti-estrogen) therapy is the core treatment modality in patients with hormone receptor positive metastatic breast cancer according to NCCN Guidelines®. Anti-estrogen therapy options for postmenopausal women with ER+ advanced breast cancer include:

•Selective ER modulators (SERM): tamoxifen

•ER antagonists: fulvestrant

•Selective nonsteroidal aromatase inhibitors: anastrozole and letrozole

•Steroidal aromatase inhibitors: exemestane

In addition, cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors are rapidly transforming the care of patients with ER+,HER2- advanced breast cancer. There are currently three CDK4/6 inhibitors that have been approved by the U.S. Food and Drug Administration: Ibrance, Kisqali, and Verzenio. It is generally recommended to use the combination of a CDK4/6 inhibitor along with an aromatase inhibitor (i.e., letrozole) for first line locally advanced or metastatic breast cancer treatment.

Illustrative breast cancer treatment landscape

Note: ORR: overall response rate; PFS: progression free survival.

Upon first line disease progression, second line therapy is most often fulvestrant (anti-estrogen) or fulvestrant plus alpelisib (Piqray), a PI3Kα inhibitor, if the patients have PIK3CA-mutated hormone receptor-positive breast cancer. Fulvestrant plus Piqray was FDA approved in 2019 based on a Phase III trial of 572 patients that demonstrated a progression free survival (PFS) of 11.0 months vs. 5.7 months in the Piqray plus fulvestrant arm compared with fulvestrant alone (HR, 0.65, 95% CI 0.50–0.85). However, a total of 25% of patients discontinued Piqray plus fulvestrant therapy due to toxicities, thus, emphasizing the need for novel agents. Upon progression on second line therapy, mammalian target of rapamycin (mTOR) inhibitors, including everolimus (Afinitor), plus anti-estrogen based regimen or chemotherapy is administered. One key limitation of both the Afinitor and Piqray studies is the lack of data for the role of these agents after prior CDK4/6 inhibitor therapy. Most patients progress on these treatments and ultimately develop resistance. At that time, patients typically live for less than two years.

Preclinical data

The female ovarian hormones estrogen and progesterone are master regulators of normal breast development and play a key role in breast cancer. Acting through ER and PR, estrogen and progesterone play complex, essential, and coordinated roles in the development of the lobular alveolar epithelial structures of the normal breast during puberty, the normal menstrual cycle, and pregnancy. It is likely that these actions become subverted in the development of breast cancer, implicating both estrogen and progesterone in the development and progression of this disease. Breast cancer is acknowledged to be a hormone-dependent disease and most breasts express ER and/or

PR. PR is expressed in humans as two major forms, progesterone receptor A (PR-A) and progesterone receptor B (PR-B), in normal cells and in certain malignant tissues. PR-A and PR-B mediate the effects of progesterone by association with a range of co-regulatory proteins and progesterone-regulated gene promoters. Over the past few decades, the estrogen receptor signaling pathway remains the most effective treatment for the management of ER+ breast cancer. Treatments include the selective estrogen receptor modulator (SERM) tamoxifen that binds to ER and prevents its activation, and aromatase inhibitors that block endogenous hormone synthesis.

Recent published data suggests that progesterone receptor may function as an anti-estrogen resistance mechanism. Long term exposure of cancer cells to anti-estrogens results in a complex resistance profile that limits the utility of standard of care anti-estrogen and CDK4/6 inhibitors. Mechanisms of resistance include mutations in estrogen receptor gene (ESR1) and ER pathway signaling (MAPK, PI3Kα, mTOR), as 20-35% of ER+,PR+,HER2-metastatic breast tumors are ESR1 mutated. The prevalence of resistance mutations is correlated with PR enrichment and activity. We have presented data showing that therapeutic inhibition of PR with either onapristone alone or in combination with anti-estrogens and/or CDK4/6 inhibitors results in the impaired growth or death of resistant cells.

As shown below, estrogen receptor (ESR1) mutational profiles of tumor biopsies were taken before and after prolonged treatment with anti-estrogen (fulvestrant) and CDK4/6 inhibitor (palbociclib) therapy. ESR1Y537S mutations are enriched by the end of therapy and are associated with worse outcomes in patients. To determine the effect of ESR1 mutations, wild type (ESR1) and mutant (ESR1Y537S and ESR1Y537N) estrogen receptors were overexpressed in the T47D breast cancer cell line. The orange box denotes that both the PR-A and PR-B isoforms of progesterone receptor demonstrated increased expression upon exposure to the mutant form of ESR1. The increased expression of PR was found to be correlated with enhanced PR activity. To establish that ESR1Y537S cells require PR for growth and dual ER-PR inhibition (i.e., complete hormone blockade) results in growth inhibition, an ex vivo organoid model was conducted using the rapidly proliferating, CDK4/6 inhibitor resistant WHIM20 cell line. Organoid data demonstrates that dual blockade of ER and PR via treatment with fulvestrant and onapristone results in growth inhibition in a cell model that is intended to mimic human disease.

Addition of Onapristone to Standard of Care Enhances Tumor Regression

Our hypothesis is that complete hormone blockade via downregulation of estrogen receptor (ER) and progesterone receptor (PR) signaling pathways, and their compensatory pathways, including CDK4/6, will lead to enhanced therapeutic outcomes in patients. To test this hypothesis, we utilized a patient-derived xenograft (PDX) model to evaluate the efficacy of the antiprogestin onapristone in combination with fulvestrant (antiestrogen) and palbociclib (CDK4/6 inhibitor) in PDX mouse models established from ER and PR positive bone metastasis of breast cancer. Two PDX models were tested, one with low level (data not shown) and one with high level of PR expression (data shown below). In the PDX model with high expression of PR, treatment by onapristone combined with palbociclib and fulvestrant resulted in enhanced tumor regressions.

All treatment arms were well tolerated. Blood and tumor samples were taken at the end of the study from both experiments. Different biological analyses will be performed to analyze ER/PR signaling by protein and RNAseq analyses.

Results from the experiment with the PR High Expression PDX are shown above. Treatment by onapristone alone resulted in a tumor growth inhibition (TGI) of 42%, while the combination onapristone (10 mg/kg) + palbociclib (75 mg/kg) resulted in a TGI of 67% and the triple combo onapristone + palbociclib + fulvestrant (5 mg/mouse) in a TGI of 92% with 6/7 xenografts showing tumor regression. The statistical analysis was performed with GraphPad software. Plasma and tumor samples were taken at the end of the study from 5 xenografts/group for further analysis.

Resistance to hormone-dependent gynecologic cancer

Gynecologic cancer overview

Ovarian and endometrial cancer represent the majority of gynecologic cancers. It is estimated that there are more than 22,000 new cases of ovarian cancer and 61,000 new cases of endometrial cancer annually, resulting in14,000 ovarian and 12,000 endometrial deaths in the United States (US) every year. As of 2019, it is estimated that there are 235,000 patients living with ovarian cancer and over 770,000 patients living with endometrial cancer in the US. By applying PR positivity (PR+) rates to the 2019 prevalence count, it is estimated that there are 300,000 patients with recurrent gynecologic cancer in the US, 130,000 of whom are PR+.

Maximal surgical debulking and platinum chemotherapy are the cornerstone treatments for primary gynecologic cancer. The aim of surgery is to confirm diagnosis, define extent of disease spread (staging), and resect all visible tumor tissue. The goal of cytoreductive surgery is removal of the entire tumor burden to achieve either complete removal of the tumor upon visual inspection (complete cytoreductive surgery) or a residual tumor of < 1 cm (optimal cytoreductive surgery). Even centers experienced in ovarian tumor cytoreductive surgery achieve optimal resection in only 50% of patients. Patients with incomplete/suboptimal cytoreductive surgery are at a significantly higher risk of recurrence and poor prognosis.

Following primary treatment for gynecologic cancer, the relapse rate is approximately 20-25% for early-stage disease and 70% for advanced (spread beyond primary site) disease. The survival curve after recurrence never plateaus, which means that the goal of treatment for recurrent gynecologic cancer is controlling the disease and disease-related symptoms, limiting treatment-related toxicity, and maintaining or improving quality of life. Primary or secondary resistance is the main cause for diminished effectiveness over time of platinum-based chemotherapy, contributing to the dismal outcome of advanced patients whose 5-year survival rate is less than 30%. Patients who are hormone receptor positive will often receive anti-estrogen therapy in the recurrent setting; however, anti-estrogen efficacy is modest in this setting. In general, treatment of recurrent disease is palliative and is initiated with the goals of controlling disease-related symptoms, limiting treatment-related toxicity, maintaining or improving quality of life, delaying time to progression, and prolonging survival.

Illustrative hormone-dependent gynecologic treatment landscape

Reasons Why Such a Therapy is Needed

Cytoreductive surgery followed by combination platinum and taxane chemotherapy is the first-line treatment for most gynecologic cancer patients regardless of type. Outside of DNA repair deficient high grade serous ovarian cancer, there are limited treatment options for all other forms of ovarian and endometrial cancer. Given the above-mentioned 5-year survival rate of less than 30%, there is a critical need to identify a targeted treatment in the recurrent setting. Ovarian and endometrial cancer remains a serious, life threatening, unmet medical need, resulting in more than 26,000 estimated deaths in the US every year.

Preclinical data

PR in Endometrial Cancer

Progesterone receptor (PR)-targeted therapies are modestly active in patients with endometrial cancer, which may be attributed to an evolving understanding of the underlying molecular mechanisms of PR-targeted therapies for this disease. In the normal endometrium, estrogen drives proliferation of the endometrial glandular epithelium, whereas progesterone counteracts the effects of estrogen. Progesterone acts by binding to the PR and has a dual role through both genomic and nongenomic pathways. Anti-progestins such as onapristone have recently been shown to be efficacious in mouse models of uterine cancer, suggesting that PR blockade may be an effective approach for treating uterine cancer.

It has been reported that mitogen-activated protein kinases (MAPK) play a dual role in PR subcellular trafficking and aid in the rapid nuclear association of PR via Serine 294 (S294) phosphorylation in response to growth factors and in response to ligand (i.e., progesterone). In Huang et al 2017, PR+ endometrial cancer cells were implanted in mice and upon tumor engraftment were treated with onapristone and/or trametinib, a MEK inhibitor. If progesterone receptor does coordinate endometrial cancer response through MAPK via MEK signaling, then the MEK inhibitor, trametinib, should be anticipated to enhance onapristone sensitivity through blocking the nuclear translocation of phosphorylated PR. The study demonstrates that PR+ endometrial xenografts are sensitive to both onapristone and trametinib alone, and exhibit synergy when combined, indicating a rationale to develop onapristone alone or in combination with a MEK inhibitor for PR+ endometrial cancer.

PR in Ovarian cancer

Progesterone and progesterone receptors (PR) are increasingly gaining attention for their emerging role as critical regulators of breast, ovarian, and endometrial cancer. Progesterone is a steroid hormone that is produced primarily by the corpus luteum in the ovaries during the second half of the menstrual cycle or luteal phase. Cyclical hormone exposure beginning at menarche and ending in menopause occurs monthly and regulates the growth and differentiation of specialized tissues within the reproductive tract and breast tissues. Until recently, little was known about the relative distribution of PR within the subtypes of ovarian tumors. In a cohort of 504 ovarian tumors, Diep et al (2013) reported that 35% of the tumors were progesterone receptor-positive (PR+) and that PR expression is associated with better outcomes, indicating a potential role for hormone therapy in PR+ ovarian cancer. Importantly, several subtypes were found to be highly enriched for PR. Retrospective studies evaluating the association of total PR expression and progression-free disease survival support the concept that subsets of PR+ ovarian tumors are highly sensitive to hormones and thus more likely to respond to endocrine therapy.

Precedent Formulation – Onapristone IR (ONA-IR)

Onapristone was originally developed in an immediate release or “IR” form (onapristone IR; ONA-IR). ONA-IR was first evaluated as an oral contraceptive and was dosed up to 400 mg/day for periods of 7 days during single ovulatory cycles in healthy female subjects. Later, ONA-IR 100 mg/day was administered for periods exceeding 12 months in breast cancer studies. Discontinuation of ONA-IR development by the original sponsor, Schering AG, is thought to have been due to the observation of liver test abnormalities and the perceived risk of drug-induced liver injury (DILI) during a Phase 2 study of ONA-IR as first line therapy in breast cancer subjects. Liver test elevations were considered a concern for the planned contraception and benign gynecological indications (e.g., uterine fibroids,

endometriosis). However, renewed interest in anti-progestin therapy for PR-positive malignancies has led to the consideration of new strategies for reducing potential hepatotoxic effects of onapristone.

In developing new strategies for anti-progestin use, one consideration is that mifepristone, ulipristal, telapristone, and onapristone all contain a 17-carbon steroid ring structure that is typical of steroids. Anti-progestins with steroidal cores often display significant cross-reactivity with closely related steroid receptors, namely, androgen receptor (AR), glucocorticoid receptor (GR), and mineralocorticoid receptor (MR). This functional overlap is partly responsible for the side effects linked with the steroidal drugs, which themselves carry a potential DILI risk. Because onapristone binds to GRs less efficiently than to PRs, one strategy to minimize liver test elevations was to seek a new onapristone formulation that yielded steady state pharmacokinetic (PK) parameters where: (a) Cmax is lower than the Cmax associated with ONA-IR 100mg QD (to target a reduced risk for LFT elevations); and (b) Cmin is at least approximately equal to the Cmin associated ONA-IR 100mg QD (to target at least equivalent, sustained suppression of PR activity). Various formulation strategies were evaluated and a 50mg, BID (twice-daily), extended release tablet (onapristone XR; ONA-XR) was selected to be the second-generation dosage form for the clinical evaluation of onapristone in PR-positive cancers.

Novel Formulation – Onapristone XR

Pharmacokinetic (PK) parameters for ONA-IR 100mg QD and ONA-XR 50mg BID were previously evaluated within a dose escalation component of a Phase 1-2 clinical study in female subjects with endometrial carcinoma, breast cancer or ovarian cancer. This study (Cottu et al 2018) reported that ONA-XR showed “Clinical benefit with excellent tolerance”, while defining a recommended phase 2 dose level of ONA-XR of 50mg, BID. The PK dataset from this clinical study enabled a direct comparison between Cmax and Cmin for ONA-IR 100mg QD and ONA-XR 50mg BID. Steady-state pharmacokinetics of ONA were estimated using standard noncompartmental methods and the nonparametric superposition tool in Phoenix WinNonlin version 8.3 (Certara Inc., Princeton, NJ). These methods assume linear pharmacokinetics from the first dose to steady state. Dosing with ONA-XR 50mg BID resulted in a steady-state Cmax almost 3 times lower than the Cmax for ONA-IR 100mg QD, while the steady-state Cmin for both formulations were similar: 829 ng/mL versus 790 ng/mL for ONA-IR versus ONA-XR, respectively. The findings of the Phase 1-2 PK and safety evaluation support that the recently developed, extended release form of onapristone appears to have achieved the PK goals of the formulation exercise.

Completed clinical trials

The initial IR formulation (ONA-IR), developed by Schering AG at various strengths, was dosed up to 400 mg/day in healthy volunteers and 100 mg/day for periods exceeding six months in oncology studies. Arno Therapeutics (Cranbury, NJ) subsequently developed onapristone extended release (“ONA-XR”) formulation and administered it in doses of 10, 20, 30, 40 and 50 mg ONA-XR BID for up to 52 weeks. We acquired ONA-XR from Arno Therapeutics. There are no associated future payments due to Arno.

Onapristone IR Clinical Data

Across first and second line metastatic breast cancer, onapristone IR (ONA-IR) demonstrated clinical activity comparable to anti-estrogen standard of care. We believe that by selecting for PR+ status and combining ONA-XR, an improved form of ONA-IR, with anti-estrogen therapy to promote complete hormone blockade, we will potentially generate superior efficacy data compared to the current standard of care treatment options.

First Line Locally Advanced or Metastatic Breast Cancer

A Phase 2 study investigating onapristone (ONA-IR, 100 mg/day as a single daily dose) as first-line endocrine therapy in patients with breast cancer was conducted as an investigator-initiated study, as shown below. Nineteen patients, either with locally advanced breast cancer (n = 12) or who were elderly with primary breast cancer and considered unfit for standard of care (n = 7) received ONA-IR. In 17 of the 19 patients, tumors expressed ER while 12 of 18 tumors tested expressed PR.

Among 18 patients who were evaluable for response, 10 had a partial response and 2 had stable disease (“SD”) for six months or more. The median duration of objective response and SD was 70 weeks. Ten patients were ER-positive/PR-positive, of whom 7 achieved partial response (PR; tumor shrinkage of >30%) and 1 had SD. Overall, the clinical benefit rate was considered comparable to the current standard of care of letrozole (anti-estrogen) and palbociclib (CDK4/6 inhibitor).

Second Line Metastatic Breast Cancer

A non-randomized, open label, multicenter Phase 2 study was conducted at 13 sites in Germany and the United Kingdom, as shown below. The study goal was to investigate the efficacy and safety of ONA-IR when given 100 mg/day to post-menopausal women with advanced breast cancer who had progressed on tamoxifen, a selective estrogen receptor modulator therapy. The study was also designed to assess the influence of onapristone on the levels of relevant endocrine parameters (cortisol, androstenedione, estrone and estradiol).

Of the 101 evaluable patients, 1 had a complete response (“CR”), 9 had a partial response, and 39 had SD for three months or more. The median duration of response was 11 months. Median time to progression was 4 months.

In second line metastatic breast cancer, ONA-IR exhibited monotherapy activity in patients who had progressed while on tamoxifen. In this trial, patients were not screened for progesterone receptor positive (PR+) status, meaning that only 60% of enrolled patients would have expected to be PR+ based upon historical prevalence in this setting and therefore derive clinical benefit from ONA-IR. Therefore, this trial potentially under-represents the likely true clinical benefit of ONA-IR had patients been stratified for the partial response biomarker. Despite administering a monotherapy without patient selection for PR+, ONA-IR demonstrated comparable clinical activity to standard of care anti-estrogens (FUL), CDK4/6 inhibitors (PAL), and the combination of the two (FUL + PAL).

Onapristone XR Clinical Data

Overall, 128 subjects received at least a single dose of ONA-XR across both healthy volunteer and cancer trials through December 31, 2020. Multiple drug product formulations of onapristone have been developed for evaluation throughout the clinical development program. Clinical development was initiated with a 10 mg immediate release (IR) capsule. An IR tablet formulation (10mg, 25 mg) and extended release (XR) tablet formulation (2.5 mg, 5 mg, 10 mg, and 20 mg) were also developed. The tablets have been administered as a single tablet or in multiples in order to obtain the desired dosage. The XR tablet has been used in ongoing safety and efficacy studies.

Thirty-one subjects (27%) of the total onapristone safety set (n = 128) experienced any treatment emergent adverse event (TEAE), as shown below. Adverse events were generally consistent across all defined groups. Thirteen subjects experienced Grade 3 or Grade 4 TEAEs that were deemed related to ONA-XR with no correlation across dosing groups. The most common drug-related TEAEs included an increase in gamma-glutamyltransferase in nine subjects (7%) and an increase in aspartate aminsotranferase in four subjects (3%). These events are generally consistent with prior anti-progestin experience, including onapristone. In addition, there were no clinically significant post-dose changes in electrocardiograms (ECGs), vital signs, or safety laboratory results.

Advanced, Recurrent Metastatic Breast Cancer

In a multicenter, open label, Phase 1 trial, Cottu et al (2018) enrolled 52 adult patients with PR+ tumors, including 20 patients with breast cancer. Patients were randomized to five cohorts of ONA-XR tablets of 10, 20, 30, 40 or 50 mg BID, or immediate release 100 mg QD until progressive disease or intolerability. All patients were heavily pre-treated; prior treatments included median (range): chemotherapy 4 (1–11), endocrine therapy 1 (1–7), biologic/small molecule therapy 1 (1–2), and radiotherapy 1 (1–3).

Among the 20 heavily pre-treated breast cancer patients, no CR or partial response were observed, 7 patients had SD, including 3 patients with SD lasting for at least 24 weeks (15% clinical benefit rate). The number of prior therapies was 3, 7 and 7, respectively, for these 3 patients and 2 of these 3 patients had liver metastases at baseline. The study authors concluded that the new XR formulation of onapristone was well tolerated and resulted in meaningful clinical benefit in heavily pretreated patients with breast cancer.

The only treatment-related serious adverse events were G3 LFT elevations (n = 4; 8%), all associated with disease progression in the liver as reviewed. These occurred across dose cohorts: 10 mg BID (AST increased, bilirubin increased), 20 mg BID (LFTs abnormal), and 40 mg BID (bilirubin increased). No relationship was found between adverse events and study drug exposure.

No treatment-related deaths were reported. One patient died within 30 days of last dose (respiratory distress syndrome due to progressive lung metastases). No other significant adverse events attributable to the mechanism of action were recorded.

Advanced, Recurrent Metastatic Gynecologic Cancers

A Phase I dose escalation study of ONA-XR in breast, endometrial, and ovarian cancer patients found all doses tested to be safe and well tolerated, with 50mg BID administered orally recommended as the Phase 2 dose. The most common treatment-related adverse events reported by investigators ( 10%) were nausea, fatigue and constipation. In that Phase I study, 33% of ovarian and 25% of endometrial cancer patients were seen to have sustained disease control.

Focusing on the ovarian cancer (n=13) subpopulation, all PR+ ovarian patients were heavily pre-treated; prior treatments included median (range): chemotherapy 4 (2–6), and treatment lines in metastatic setting 4 (2-10). All patients were platinum resistant. Clinical data is shown below.

Phase 1 ovarian cancer data

Advanced, Recurrent Granulosa Cell Tumor of the Ovary

Granulosa cell tumors (GCT) of the ovary is a rare form of ovarian cancer. These tumors account for 2-5% of all ovarian malignancies and it is estimated that there are approximately 5,000 patients with recurrent disease in the US and EU.

Almost all GCT tumors are progesterone receptor (PR) positive, whereas about 50% are estrogen receptor (ER) positive. These tumors often produce estrogen and progesterone, which can cause symptoms such as abnormal vaginal bleeding or breast tenderness. Further, PR expression is correlated with worse outcomes in GCT patients. GCT tumors have a low mitotic ratio and few actionable mutations, which limits the applicability of chemotherapeutic and precision medicine approaches. Platinum-based chemotherapy is recommended as the first line of treatment for patients in the metastatic setting. Following progression to metastatic disease, patients typically cycle through chemotherapy, antihormonal treatments, and cytoreductive surgeries. There are currently no FDA treatments for GCT tumors of the ovary, and few, if any, open clinical trials.

Given that GCT tumors are hormone driven, it is plausible that complete hormone blockade via antiprogestin and antiestrogen therapy may provide a therapeutic benefit to patients. In 2019, Memorial Sloan Kettering Cancer Center initiated an Investigator-sponsored Trial to evaluate onapristone extended release (ONA-XR) in women with GCT of the ovary who had progressed on multiple prior therapies.

Phase 2 data evaluating ONA-XR in late line GCT of the ovary

Fourteen patients with progesterone receptor positive (PR+) GCT of the ovary were enrolled in the trial, with thirteen of those patients completing at least one full cycle of treatment.

Four of the 14 patients (29%) had clinical benefit lasting at least 24 weeks, and 5 additional patients (64%) experienced stable disease as best response. Importantly, two patients (14%) remain on treatment after 12 months. To date, no significant treatment-related adverse events have been identified. The most common treatment-related adverse events reported were nausea, fatigue, and constipation.

Based on the Phase 2 monotherapy data presented above, a combination arm seeking to enroll 25 patients was activated to evaluate the combination of ONA-XR with anastrozole, a selective nonsteroidal aromatase inhibitor. Aromatase inhibitors are commonly used to treat recurrent granulosa cell tumors based on low response rates to chemotherapy and historically high rates of ER/PR expression within these tumors. However, objective response rate for anastrozole remains low and was found to be 2.5% in a recent clinical trial (Banerjee, JCO, 2018). We seek to test the combination of ONA-XR and anastrozole to enhance the response rate in patients with PR+ GCT tumors of the ovary.

We have FDA Fast Track designation for PR+ ovarian cancer

In August 2020, we received FDA Fast Track designation for ONA-XR in PR+ ovarian cancer. Fast Track designation is designed to facilitate the development and expedite the review of therapies for serious conditions and fill an unmet medical need. Programs with Fast Track designation may benefit from early and frequent communications with the FDA, potential priority review and the ability to submit a rolling application for regulatory review. Fast Track designation applies to both the product candidate and the specific indication for which it is being studied. If any of our product candidates receive Fast Track designation but do not continue to meet the criteria for Fast Track designation, or if our clinical trials are delayed, suspended or terminated, or put on clinical hold due to unexpected adverse events or issues with clinical supply, we will not receive the benefits associated with the Fast Track program. Furthermore, Fast Track designation does not change the standards for approval. Fast Track designation alone does not guarantee qualification for the FDA’s priority review procedures.

Clinical development plan for ONA-XR

The PR signaling pathway has been implicated in female hormone-dependent cancers, including breast, ovarian, and endometrial cancer. Our clinical development effort for ONA-XR, a selective and potentially potent small molecule antagonist of PR, will initially focus on indications where there is evidence suggesting PR-mediated signaling contributes to resistance and disease progression. In 2020, a Phase 2 investigator-sponsored trial was initiated in collaboration with Thomas Jefferson University to evaluate ONA-XR in combination with Arimidex (anastrozole) in PR+ endometrial cancer and preliminary data is expected in the second half of 2022. Also, in 2020 we initiated a Phase 0 trial of ONA-XR in a window of opportunity study in primary breast cancer, and we reported preliminary data at the San Antonio Breast Cancer Symposium in December 2021. In 2021, a Phase 1b/2 investigator-sponsored trial was initiated in collaboration with Memorial Sloan Kettering Cancer Center to evaluate ONA-XR in combination with Ibrance (palbociclib) and Femara (leterozole) in first line metastatic breast cancer patients with biochemically recurrent disease, defined as circulating tumor DNA (ctDNA) positive. This is potentially a new clinical opportunity for the estimated 20% of 1L patients who are at high risk of early disease progression on Ibrance and Femara therapy. In 2021, we completed the first stage of our Phase 2 trial evaluating ONA-XR in recurrent granulosa cell tumors (GCT) of the ovary and in July 2021 we initiated the second stage of this trial evaluating ONA-XR in combination with the antiestrogen, anastrozole. Also in 2021, a Phase 2 investigator-sponsored trial was initiated in collaboration with Wisconsin Oncology Network to evaluate ONA-XR in combination with Faslodex (fulvestrant) in second or third line metastatic breast cancer. This trial is intended to establish ONA-XR plus Faslodex drug synergy after treatment failure of CDK4/6 inhibitor and/or PIK3α inhibitors. We expect to report preliminary data from one of these trials in the first half of 2022. In 2021, we also initiated a sub-study of our Phase 2 trial in second or third line metastatic breast cancer, which evaluates the F-FFNP PET uptake in breast tumors, with preliminary data expected to come in the second half of 2022.

CLDN6xCD3 bispecific antibody program: CLDN6xCD3 bsAb

Background CLDN6

Claudin 6 (CLDN6) is an oncofetal tight junction protein involved in the cell-to-cell adhesion of epithelial and endothelial cell sheets. Although silenced in healthy adult human tissues, CLDN6 expression has been found in ovarian, gastric, pediatric, and other cancer tissues and can lead to a poor prognosis. Monoclonal antibody (MAb) discovery against CLDN6 has been encumbered by the high homology of endogenously expressed claudin 9 (CLDN9), which varies from CLDN6 by only 3 amino acids in the extracellular domain.

Proposed mechanism of action

Rationale for bispecific antibody

Cytotoxic T cells are considered to be the most potent effector cells of the immune system. As a consequence, broad T cell activation can lead to significant and sometimes lethal side effects. Therefore, to harness the potential of cytotoxic T cells, therapeutic strategies seek to pair T cell activation with drug targets that are restricted to cancer

tissue so as to avoid unwanted toxicity. CLDN6 expression is restricted to various cancer types (i.e., a tumor specific antigen or TSA), making it an ideal target to help T cells recognize and eliminate cancer cells. Recently, a class of bispecific antibodies (TSAxCD3) with a native immunoglobulin format has emerged that can efficiently trigger T cell–mediated killing of tumor cells by linking a T cell to a tumor cell and activating the CD3/t cell receptor complex, as shown above.

CLDN6 expression in cancer versus normal tissue

Preclinical data

CLDN6xCD3 bsAb, is an anti-CD3 x anti-Claudin 6 (CLDN6xCD3) antigen bispecific monoclonal antibody (bsAbs) that is intended to redirect T-cell-mediated lysis toward malignant cells expressing CLDN6. As shown below, preclinical studies demonstrate that CLDN6xCD3 bsAb exhibits selectivity for CLDN6 over CLDN9 and that CLDN6xCD3 bsAb mediates strong T-cell activation and specific lysis of cells expressing CLDN6. In vivo studies with a prototype bispecific of CLDN6xCD3 bsAb demonstrated dose-dependent tumor regressions in an established ovarian cancer xenograft model with an intact immune system. We expect to initiate IND-enabling studies for CLDN6xCD3 bsAb with the FDA in 2022.

CLDN6 x CD3 bispecific retains selectivity of parental mAb

Figure above illustrates the results of a binding assay showing that Context’s Claudin 6 monoclonal and bispecific antibodies bind to Claudin 6 preferentially over other Claudin proteins. Human embryonic kidney 293T (HEK-293T) cells were transiently transfected with DNA for the indicated Claudin protein along with GFP (pUC) for 22 hours.

Context bispecifics activate T cells against CLDN6+ cells

Figure above illustrates the results of immune assays showing that Context’s CLDN6 x CD3 bispecific antibodies activate T cells and drive T-cell dependent cytotoxicity. All bispecific formats contain the same CD3 cassette. Activity was measured after 72 hours of treatment.

Comparison of CLDN6 development programs

We have performed head-to-head in vitro studies comparing internally developed CLDN6 monoclonal antibodies and those from BioNTech and Xencor. Antibodies for BioNTech and comparative data for Xencor were derived from publicly available reports published independent of the Company and may differ in material ways from the actual antibody that is in development.

The results presented in the below table have been derived from publicly available reports of preclinical studies and clinical trials run independently of our trials or meta-analyses of such clinical results. We have not performed any head-to-head trials comparing any of these other therapies with CLDN6xCD3 bsAb. As such, the results of these other clinical trials may not be comparable to clinical results for CLDN6xCD3 bsAb. The design of these other trials vary in material ways from the design of the clinical trials for CLDN6xCD3 bsAb. For further information and to understand these material differences, you should read the relevant reports or meta-analyses.

While the BioNTech and Xencor’s product candidates are not intended to compete with our CLDN6xCD3 bsAb, it is useful to compare the symptomatic results achieved by their devices and approaches a good proxy to understand the adoption of these therapies.

Under the terms of the agreement, Tyligand is responsible for ONA-XR manufacturing process optimization. As a part of the agreement, Tyligand is eligible to receive development milestone payments of $0.8 million and a certain number of warrants exercisable for common stock upon successful completion of the manufacturing development plan, $2.0 million upon the completion of scale-up of the first cumulative 100 kilograms of the GMP-grade compound and $3.0 million upon our completion of scale-up of the first cumulative 300 kilograms of the GMP-grade compound. We will also pay Tyligand a 1% royalty of net sales of finished product commercialized in any country (other than the People’s Republic of China, including Hong Kong and Macau) utilizing the compound substantially manufactured in accordance with the process and specifications outlined in this agreement. This agreement terminated in August of 2021, subject to certain surviving and ongoing obligations. Please note that this is just a summary of the Tyligand Process Development Agreement; for complete terms, please see the agreements to be attached as exhibits to the registration statement of which this prospectus forms a part.

In August of 2021, Tyligand achieved “successful completion” under the Tyligand Process Development Agreement as a result of Tyligand’s successful optimization of the ONA-XR manufacturing process. Because of this achievement, Tyligand has entered into a license agreement with us (the “Tyligand License Agreement”) whereby we have granted Tyligand an exclusive license to develop and commercialize ONA-XR in the People’s Republic of China, including Hong Kong and Macau (the “Tyligand Territory”), subject to Tyligand paying Context a mid-single digit royalty of net sales of ONA-XR in such countries. The royalty term of such exclusive license shall be the from period beginning on the date of the first commercial sale of ONA-XR in the Tyligand Territory and ending on the latest of (i) the sale of a generic product containing the same active pharmaceutical ingredients as ONA-XR in the Tyligand Territory, and (ii) fifteen (15) years after the date of the first commercial sale of ONA-XR in the Tyligand Territory. We have retained our global exclusive rights for ONA-XR for the remainder of the world. As a result of the completion of this milestone, Tyligand has been granted a warrant to purchase 111,576 shares of our common stock at an exercise price of $7.17 per share and will be paid $800,000 and Tyligand will be eligible to receive manufacturing and development milestone payments totaling up to $5.0 million upon the achievement of

certain future milestones. The Tyligand License Agreement provides for termination in the event of (a) insolvency, (b) a material breach of the agreement, and (c) in the event that Tyligand does not meet certain regulatory milestones. Please note that this is a summary of the Tyligand License Agreement; for complete terms, please see the agreements to be attached as exhibits to the registration statement of which this prospectus forms a part.

In April 2021, we entered into a license agreement with Integral for the exclusive worldwide rights (the “Integral License Agreement”) to certain Claudin 6 antibody patents in the field of bispecific antibodies. Under the terms of the license and development agreement, we are responsible for all costs associated with CLDN6xCD3 bsAb development as well as certain success-based payments, including milestone and royalty payments, to Integral. We paid an upfront license fee of $0.3 million and granted 418,559 Series A Units with a fair market value of approximately $2.8 million. As a part of the agreement, Integral will be eligible to receive development and regulatory milestone payments totaling up to $55.3 million, sales milestone payments totaling up to $130 million, and tiered royalties of up to 12% of net sales of certain products developed under this agreement. We shall continue to pay royalties on a country-by-country and licensed-by-licensed product basis, until the later of: (i) the expiration of the patent covering such product in such territory, (ii) the expiration of any regulatory exclusivity granted with respect to a product in such territory and (iii) ten years from the first commercial sale of such product in such country. The agreement shall continue in full force and effect, until either (a) royalty payments for all products in all territories have expired or (b)(i) we provide written notice of termination, (ii) during three successive quarters we do not use commercially reasonable efforts to develop a product, (iii) if the agreement is breached or (iv) if a party goes bankrupt. Please note that this is a summary of the Integral License Agreement, for complete terms, please see the agreement attached as an exhibit to the registration statement of which this prospectus forms a part.

Commercialization

We retain worldwide development and commercialization rights for ONA-XR outside of Greater China and retain full worldwide development and commercialization rights to certain CLDN6 antibody patents in the field of bispecific antibodies and to certain patents related to Sigma1. We periodically evaluate out-license opportunities for our product candidates, including our lead product candidate ONA-XR, and seek to identify drug candidates for novel indications and/or patient subpopulations with an oncology focus that we might in-license. Our commercial plans and strategy for each particular program may change as programs advance, markets change, and we receive more clinical data, and will depend on availability of current and future capital.

Sales and marketing

We currently have no sales, marketing, or commercial product distribution capabilities, and we may explore partnerships with larger pharmaceutical organizations to out-license our product candidates, including our lead product candidate ONA-XR. We intend to build the necessary infrastructure and capabilities over time for the United States, and potentially other regions, following further advancement of our product candidates.

Manufacturing

We do not own or operate, and currently have no plans to establish, any manufacturing facilities. We rely, and expect to continue to rely, on third parties for the manufacture of our product candidates for preclinical and clinical testing, as well as for commercial manufacture if any of our product candidates obtain marketing approval. We also rely, and expect to continue to rely, on third parties to package, label, store and distribute our investigational product candidates, as well as for our commercial products if marketing approval is obtained. We believe that this strategy allows us to maintain a more efficient infrastructure by eliminating the need for us to invest in our own manufacturing facilities, equipment and personnel while also enabling us to focus our expertise and resources on the development of our product candidates.

To date, we have obtained active pharmaceutical ingredients (API) and drug product for our product candidates from several third party contract manufacturers. We are in the process of developing our supply chain for each of our product candidates and intend to put in place framework agreements under which third-party contract manufacturers will generally provide us with necessary quantities of API and drug product on a project-by-project basis based on our development needs.

As we advance our product candidates through development, we will consider our lack of redundant supply for the API and drug product for each of our product candidates to protect against any potential supply disruptions.

We generally expect to rely on third parties for the manufacture of any companion diagnostics we may develop.

Competition

The pharmaceutical and biotechnology industries are characterized by rapidly advancing technologies, intense competition, and a strong emphasis on proprietary products. While we believe that our technology, the expertise of our executive and scientific team, research, clinical capabilities, development experience and scientific knowledge provide us with competitive advantages, we face increasing competition from many different sources, including pharmaceutical and biotechnology companies, academic institutions, governmental agencies and public and private research institutions. Product candidates that we successfully develop and commercialize may compete with existing therapies and new therapies that may become available in the future.

Many of our competitors, either alone or with their collaborators, have significantly greater financial resources, established presence in the market, expertise in research and development, manufacturing, preclinical and clinical testing, obtaining regulatory approvals and reimbursement and marketing approved products than we do. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. Additional mergers and acquisitions may result in even more resources being concentrated in our competitors.

Our commercial potential could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than products that we may develop. Our competitors also may obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position before we are able to enter the market or make our development more complicated. The key competitive factors affecting the success of all of our programs are likely to be efficacy, safety and convenience.

For ONA-XR, our small molecule PR antagonist, we are aware of several companies developing PR antagonists, including Allergan, Gedeon Richter, and Evestra. To our knowledge, there are no PR antagonists approved for the treatment of cancer and the most advanced such PR antagonist is in a Phase 2 clinical trial.

For CLDN6xCD3 bsAb, our CLDN6xCD3 bispecific antibody, we are aware of several companies developing antibodies against this target, including BioNTech, Xencor, NovaRock, UCLA, Astellas, Abbvie, and Chugai. These companies are developing CDLN6 products in naked antibody, bispecific, CAR-T, and mRNA vaccine formats. To our knowledge, BioNTech has the only CLDN6 bispecific in clinical trials.

Intellectual property

We strive to protect and enhance the proprietary technology, inventions and improvements that are commercially important to our business, including seeking, maintaining and defending our patent rights. We own the issued patent and patent applications relating to our first program and lead product candidate ONA-XR, retains full worldwide development and commercialization rights to certain CLDN6 antibody patents in the field of bispecific antibodies. Our policy is to seek to protect our proprietary position by, among other methods, filing patent applications in the United States and in jurisdictions outside of the United States directed to our proprietary technology, inventions, improvements and product candidates that are important to the development and implementation of our business. We also rely on trade secrets and know-how relating to our proprietary technology and product candidates and continuing innovation to develop, strengthen and maintain our proprietary position in the field of oncology. We also plan to rely on data exclusivity, market exclusivity and patent term extensions when available. Our commercial success will depend in part on our ability to obtain and maintain patent and other proprietary protection for our product candidates, technology, inventions and improvements; to preserve the confidentiality of our trade secrets; to defend and enforce our proprietary rights, including any patents that we may

own or license in the future; and to operate without infringing on the valid and enforceable patents and other proprietary rights of third parties.

As of December 6, 2021, our patent portfolio consisted of pending or issued patents that we own or license related to our ONA-XR product candidate and various other compounds and programs. Specifically, we owned four issued U.S. patents, three pending U.S. patent applications, one granted Canadian patent, two granted Chinese patents, one granted Japanese patent, three granted Australian patents, one granted Hong Kong patent, and 18 pending foreign patent applications, two of which are Australian applications, three of which are Canadian applications, two of which are Chinese applications, three of which are European regional patent applications, two of which are Hong Kong applications, one of which is a Mexican application, two of which are Japanese applications, two of which are Korean applications, and one international PCT application.

More specifically with respect to ONA-XR, our issued U.S. patents in our owned portfolio described above have claims directed to our ONA-XR as pharmaceutical compositions, formulations, and related methods of use, and methods of making. These U.S. patents are expected to expire between 2034 and 2036, subject to any extensions or disclaimers.

We also possess substantial know-how and trade secrets relating to the development and commercialization of our product candidates, including related manufacturing processes and technology.

With respect to our product candidates and processes we intend to develop and commercialize in the normal course of business, we intend to pursue patent protection covering, when possible, compositions, methods of use, dosing and formulations. We may also pursue patent protection with respect to manufacturing and drug development processes and technologies.

Issued patents can provide protection for varying periods of time, depending upon the date of filing of the patent application, the date of patent issuance and the legal term of patents in the countries in which they are obtained. In general, patents issued for applications filed in the United States can provide exclusionary rights for 20 years from the earliest effective filing date. In addition, in certain instances, the term of an issued U.S. patent that covers or claims an FDA approved product can be extended to recapture a portion of the term effectively lost as a result of the FDA regulatory review period, which is called patent term extension. The restoration period cannot be longer than five years and the total patent term, including the restoration period, must not exceed 14 years following FDA approval. The term of patents outside of the United States varies in accordance with the laws of the foreign jurisdiction, but typically is also 20 years from the earliest effective filing date. However, the actual protection afforded by a patent varies on a product-by-product basis, from country-to-country and depends upon many factors, including the type of patent, the scope of its coverage, the availability of regulatory-related extensions, the availability of legal remedies in a particular country and the validity and enforceability of the patent.

The patent positions of companies like ours are generally uncertain and involve complex legal and factual questions. No consistent policy regarding the scope of claims allowable in patents in the field of oncology has emerged in the United States. The relevant patent laws and their interpretation outside of the United States is also uncertain. Changes in either the patent laws or their interpretation in the United States and other countries may diminish our ability to protect our technology or product candidates and could affect the value of such intellectual property. In particular, our ability to stop third parties from making, using, selling, offering to sell or importing products that infringe our intellectual property will depend in part on our success in obtaining and enforcing patent claims that cover our product candidates, technology, inventions and improvements. We cannot guarantee that patents will be granted with respect to any of our pending patent applications or with respect to any patent applications we may file in the future, nor can we be sure that any patents that may be granted to us in the future will be commercially useful in protecting our products, the methods of use or manufacture of those products. Moreover, even our issued patents may not guarantee us the right to commercialize our product candidates, if approved. Patent and other intellectual property rights in the pharmaceutical and biotechnology space are evolving and involve many risks and uncertainties. For example, third parties may have blocking patents that could be used to prevent us from commercializing our product candidates and practicing our proprietary product candidates, and our issued patents may be challenged, invalidated or circumvented, which could limit our ability to stop competitors from marketing related products or could limit the term of patent protection that otherwise may exist for our product candidates. In

addition, the scope of the rights granted under any issued patents may not provide us with protection or competitive advantages against competitors with similar products. Furthermore, our competitors may independently develop similar products that are outside the scope of the rights granted under any issued patents. For these reasons, we may face competition with respect to our product candidates. Moreover, because of the extensive time required for development, testing and regulatory review of a potential product, it is possible that, before any particular product candidate can be commercialized, any patent protection for such product may expire or remain in force for only a short period following commercialization, thereby reducing the commercial advantage the patent provides.

Government Regulation

Regulatory Pathway

We expect that ONA-XR will be classified and regulated by the FDA as a drug. We expect that our CLDN6xCD3 bsAb will be classified and regulated by the FDA as a biologic. A new drug application (“NDA”) is required to introduce a drug into interstate commerce. A biologics license application (“BLA”) is required to introduce a biologic product into interstate commerce. The specific requirements of NDAs and BLAs include applicant information, product information, manufacturing information, pre-clinical data, clinical data, and labelling. The most important, time-consuming, and expensive aspect of preparing for a BLA or NDA is conducting clinical trials to demonstrate safety and effectiveness. The requirements of such clinical trials heavily influence the eventual allowable product label claims. The FDA has a performance goal as defined in the Prescription Drug User Fee Act of ten months for a standard submission and six months for priority review. It is not uncommon for NDAs and BLAs to require medical advisory board review prior to the FDA granting marketing approval. A facility inspection verifying the manufacturing systems is also usually performed prior to FDA approval.

We have in the past used and intend to continue to utilize the services of third-party experts to supplement internal regulatory planning and implementation.

Ongoing FDA Regulation

After the FDA permits a product to enter commercial distribution, numerous and pervasive regulatory requirements continue to apply to our business operations, products and technologies. These include:

•the FDA’s quality system regulation, or QSR, which requires manufacturers, including third party manufacturers, to follow stringent design, testing, production, control, supplier/contractor selection, complaint handling, documentation and other quality assurance procedures during all aspects of the manufacturing process;

•labeling and marketing regulations which require that promotion is truthful, not misleading, fairly balanced and provide adequate directions for use and that all claims are substantiated;

•advertising and promotion requirements, including FDA prohibitions against the promotion of products for uncleared, unapproved or off-label uses and FDA guidance on off-label dissemination of information and responding to unsolicited requests for information;

•restrictions on sale, distribution or use;

•product establishment, registration and listing requirements and reporting requirements;

•recall requirements, including a mandatory recall if there is a reasonable probability that a product would cause serious adverse health consequences or death;

•an order of repair, replacement or refund; and

•post-market surveillance activities and regulations, which apply when necessary to protect the public health or to provide additional safety and effectiveness data.

The FDA has broad post-market and regulatory enforcement powers. Manufacturers of biologic products and drug products like our product candidates are subject to unannounced inspections by the FDA and other state, local and foreign regulatory authorities to assess compliance with the QSR and other applicable regulations, and these inspections may include the manufacturing facilities of any suppliers.

Failure to comply with applicable regulatory requirements can result in enforcement action by the FDA, which may include any of the following sanctions:

•warning letters, untitled letters, Form 483s, fines, injunctions, consent decrees and civil penalties;

•recall or seizure of products;

•operating restrictions, partial suspension or total shutdown of production;

•the FDA’s refusal of requests for approval of new products or indications for existing products;

•the FDA’s refusal to issue certificates to foreign governments needed to export products for sale in other countries;

•withdrawing approvals that have already been granted; and

•criminal prosecution.

Privacy and Security Laws

There are numerous U.S. federal and state laws and regulations related to the privacy and security of personal information, including health information. Among others, the federal Health Insurance Portability and Accountability Act of 1996, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and their implementing regulations, (collectively referred to as HIPAA), establish privacy and security standards that limit the use and disclosure of protected health information, or PHI, and require covered entities and business associates to implement administrative, physical, and technical safeguards to ensure the confidentiality, integrity and availability of individually identifiable health information in electronic form, among other requirements.

Violations of HIPAA may result in civil and criminal penalties. Companies subject to HIPAA must also comply with HIPAA’s breach notification rule which requires notification of affected patients and the U.S. Department of Health and Human Services, or HHS, and in certain cases of media outlets, in the case of a breach of unsecured PHI. The regulations also require business associates of covered entities to notify the covered entity of breaches by the business associate. State attorneys general also have the right to prosecute HIPAA violations committed against residents of their states, and HIPAA standards have been used as the basis for the duty of care in state civil suits, such as those for negligence or recklessness in misusing personal information. In addition, HIPAA mandates that HHS conduct periodic compliance audits of HIPAA covered entities and their business associates for compliance.

Many states have laws that protect the privacy and security of sensitive and personal information, including health information, to which we are subject. These laws may be similar to or even more protective than HIPAA and other federal privacy laws. For example, California enacted the California Consumer Privacy Act, or CCPA, which creates individual privacy rights for California consumers and increases the privacy and security obligations of entities handling certain personal data. The CCPA went into effect on January 1, 2020, and the California Attorney General may bring enforcement actions for violations as of July 1, 2020. The CCPA has been amended from time to time, and it remains unclear what, if any, further modifications will be made to this legislation or how it will be interpreted.

We may be subject to other state and federal privacy laws, including laws that prohibit unfair privacy and security practices and deceptive statements about privacy and security, laws that place specific requirements on certain types of activities, such as data security and texting, and laws requiring holders of personal information to maintain safeguards and to take certain actions in response to a data breach.

European Union member states, the United Kingdom, Switzerland and other jurisdictions have also adopted data protection laws and regulations, which impose significant compliance obligations. In the EEA and the United Kingdom, the collection and use of personal data, including clinical trial data, is governed by the provisions of the General Data Protection Regulation, or GDPR. The GDPR became effective on May 25, 2018, repealing its predecessor directive and increasing responsibility and liability of pharmaceutical and medical device companies in relation to the processing of personal data of EU data subjects. The GDPR, together with national legislation, regulations and guidelines of the EU member states and the United Kingdom governing the processing of personal data, impose strict obligations and restrictions on the ability to collect, analyze and transfer personal data, including health data from clinical trials and adverse event reporting. In particular, these obligations and restrictions concern the consent of the individuals to whom the personal data relates, the information provided to the individuals, the transfer of personal data out of the EEA or the United Kingdom, security breach notifications, security and confidentiality of the personal data and imposition of substantial potential fines for breaches of the data protection obligations. European data protection authorities may interpret the GDPR and national laws differently and impose additional requirements, which add to the complexity of processing personal data in or from the EEA or United Kingdom. Guidance on implementation and compliance practices are often updated or otherwise revised.

U.S. Healthcare Reform

Changes in healthcare policy could increase our costs and subject us to additional regulatory requirements that may interrupt commercialization of our products. By way of example, the Patient Protection and Affordable Care Act, or PPACA substantially changed the way healthcare is financed by both governmental and private insurers, and significantly impacted the pharmaceutical, medical device and biologics industries, among others.

Since its enactment, there have been judicial and Congressional challenges to certain aspects of the PPACA, and we expect there will be additional challenges and amendments to the PPACA in the future. For example, in 2017, Congress enacted the Tax Cuts and Jobs Act, which eliminated the tax-based shared responsibility payment imposed by the PPACA on certain individuals who fail to maintain qualifying health coverage for all or part of a year that is commonly referred to as the “individual mandate.” On December 14, 2018, a U.S. District Court Judge in the Northern District of Texas, or the Texas District Court Judge, ruled that the individual mandate is a critical and inseverable feature of the PPACA, and therefore, because it was repealed as part of the Tax Cuts and Jobs Act, the remaining provisions of the PPACA are invalid as well. While the Texas District Court Judge, as well as the Trump Administration and CMS, have stated that the ruling will have no immediate effect, and on December 30, 2018 the Texas District Court Judge issued an order staying the judgment pending appeal. In December 2019, a U.S. District Court upheld a ruling that the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. In November 2020, the Supreme Court of the United States heard oral arguments in the appeal of this case, but it is uncertain when the Supreme Court will rule on this case. It is unclear how this and other efforts to challenge, repeal, or replace the ACA will impact the ACA or our business.

There will continue to be proposals by legislators at both the federal and state levels, regulators and third-party payors to reduce costs while expanding individual healthcare benefits. Certain of these changes could impose additional limitations on the prices we will be able to charge and/or patients’ willingness to pay for our products. While in general it is too early to predict what effect, if any, any future healthcare reform legislation or policies will have on our business, current and future healthcare reform legislation and policies could have a material adverse effect on our business and prospects.

Pricing and Reimbursement

In the United States and markets in other countries, sales of any products for which we receive regulatory approval for commercial sale will depend in part on the availability of reimbursement from third party payors. Third party payors include government health administrative authorities, managed care providers, private health insurers, and other organizations. These third-party payors are increasingly challenging the price and examining the cost-effectiveness of medical products and services. In addition, significant uncertainty exists as to the reimbursement status of newly approved healthcare products, and efforts are underway to reduce the cost of medical products and services overall. We may need to conduct expensive studies in order to demonstrate the cost-effectiveness of our products. Our product candidates may not be considered cost-effective. Decisions regarding the extent of coverage

and amount of reimbursement to be provided are made on a plan-by-plan basis. One third-party payor’s decision to cover a particular product or procedure using the product does not ensure that other payors will also provide coverage for the product. Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to realize an appropriate revenue levels. Future legislation could limit payments for our product candidates.

The U.S. government, state legislatures and foreign governments have shown significant interest in implementing cost containment programs to limit the growth of government-paid health care costs, including price controls, restrictions on reimbursement and requirements for substitution of less costly products. Adoption of government controls and measures, and tightening of restrictive policies in jurisdictions with existing controls and measures, could limit payments for our products. The marketability of any products for which we receive regulatory approval for commercial sale may suffer if the government and third-party payors fail to provide adequate coverage and reimbursement. In addition, an increasing emphasis on managed care in the United States has increased and will continue to increase the pressure on medical product and service pricing.

Anti-Kickback and False Claims Laws

In the United States, the research, manufacturing, distribution, sale and promotion of pharmaceutical products and devices are subject to regulation by various federal, state and local authorities in addition to the FDA, including the Centers for Medicare & Medicaid Services, other divisions of the U.S. Department of Health and Human Services (e.g., the Office of Inspector General), the U.S. Department of Justice, state Attorneys General, and other federal, state and local government agencies. For example, sales, marketing and scientific/educational grant programs must comply with the FFDCA, Anti-Kickback Statute, as amended, the False Claims Act, as amended, the privacy regulations promulgated under the Health Insurance Portability and Accountability Act, or HIPAA, and similar state laws. If products are made available to authorized users of the Federal Supply Schedule of the General Services Administration, additional laws and requirements apply. All of these activities are also potentially subject to federal and state consumer protection and unfair competition laws.

As noted above, in the United States, we are subject to complex laws and regulations pertaining to healthcare “fraud and abuse,” including, but not limited to, the federal Anti-Kickback Statute, the federal False Claims Act, and other state and federal laws and regulations. The Anti-Kickback Statute makes it illegal for any person, including a biological product manufacturer (or a party acting on its behalf) to knowingly and willfully solicit, receive, offer, or pay any remuneration that is intended to induce the referral of business, including the purchase or order of an item for which payment may be made under a federal healthcare program, such as Medicare or Medicaid. Violations of this law are punishable by up to five years in prison, criminal fines, administrative civil money penalties, and exclusion from participation in federal healthcare programs. In addition, many states have adopted laws similar to the Anti-Kickback Statute. Some of these state prohibitions apply to the referral of patients for healthcare services reimbursed by any insurer, not just federal healthcare programs such as Medicare and Medicaid. Due to the breadth of these federal and state anti-kickback laws and the potential for additional legal or regulatory change in this area, it is possible that our sales and marketing practices and/or our relationships with physicians might be challenged under anti-kickback laws, which could harm us. Because we commercialize products that could be reimbursed under a federal healthcare program and other governmental healthcare programs, we plan to develop a comprehensive compliance program that establishes internal controls to facilitate adherence to the rules and program requirements to which we are subject.

The federal False Claims Act prohibits anyone from, among other things, knowingly presenting, or causing to be presented, for payment to federal programs (including Medicare and Medicaid) claims for items or services, including pharmaceutical products, that are false or fraudulent. Although we would not submit claims directly to payers, manufacturers can be held liable under these laws if they are deemed to “cause” the submission of false or fraudulent claims by, for example, providing inaccurate billing or coding information to customers or promoting a product off-label. In addition, our activities relating to the reporting of wholesaler or estimated retail prices for our products, the reporting of prices used to calculate Medicaid rebate information and other information affecting federal, state, and third-party reimbursement for our products, and the sale and marketing of our products, are subject to scrutiny under this law. For example, pharmaceutical companies have been prosecuted under the federal False Claims Act in connection with their off-label promotion of drugs. Penalties for a False Claims Act violation

include three times the actual damages sustained by the government, plus mandatory civil penalties of between $11,181 and $22,363 for each separate false claim, the potential for exclusion from participation in federal healthcare programs, and, although the federal False Claims Act is a civil statute, conduct that results in a False Claims Act violation may also implicate various federal criminal statutes. If the government were to allege that we were, or convict us of, violating these false claims laws, we could be subject to a substantial fine and may suffer a decline in our stock price. In addition, private individuals have the ability to bring actions under the federal False Claims Act and certain states have enacted laws modeled after the federal False Claims Act.

There are also an increasing number of state laws that require manufacturers to make reports to states on pricing and marketing information. Many of these laws contain ambiguities as to what is required to comply with the laws. In addition, a provision of the Patient Protection and Affordable Care Act, referred to as the Sunshine Act, requires pharmaceutical product manufacturers to track and report to the federal government certain payments or other transfers of value made to physicians, registered nurses and teaching hospitals, among others, in the previous calendar year. These laws may affect our sales, marketing, and other promotional activities by imposing administrative and compliance burdens on us. In addition, given the lack of clarity with respect to these laws and their implementation, our reporting actions could be subject to the penalty provisions of the pertinent state and federal authorities.

Other Federal Healthcare Fraud and Abuse Laws

We may also be subject to other federal healthcare fraud and abuse laws, including provisions of HIPAA, which prohibit knowingly and recklessly executing a scheme or artifice to defraud any healthcare benefit program, including private payors, as well as knowingly and willfully falsifying, concealing or covering up a material fact by any trick, scheme or device or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. A violation of this statute is a felony and may result in fines, imprisonment or exclusion from government-sponsored programs. Similar to the federal Anti-Kickback Statute, a person or entity no longer needs to have actual knowledge of this statute or specific intent to violate it in order to have committed a violation.

Foreign Corrupt Practices Act

The Foreign Corrupt Practices Act, or FCPA, prohibits U.S. businesses and their representatives from offering to pay, paying, promising to pay or authorizing the payment of money or anything of value to a foreign official in order to influence any act or decision of the foreign official in his or her official capacity or to secure any other improper advantage in order to obtain or retain business. The FCPA also obligates companies whose securities are listed in the United States to comply with accounting provisions requiring us to maintain books and records, which in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the corporation, including international subsidiaries, if any, and to devise and maintain a system of internal accounting controls sufficient to provide reasonable assurances regarding the reliability of financial reporting and the preparation of financial statements. The scope of the FCPA includes interactions with certain healthcare professionals in many countries.

Employees

As of December 1, 2021, we had five full-time employees, no part-time employees and three consultants. None of these employees are represented by labor unions or covered by collective bargaining agreements. We believe that our employee relations are good.

Facilities

Our principal executive offices are located at 3675 Market Street, Suite 200, Philadelphia, Pennsylvania 19104, where we lease approximately 60 square feet of office space. We lease this space under a month-to-month lease. We intend to add new facilities as we believe that suitable additional or substitute space will be available as needed to accommodate any such expansion of our operations.

Legal Proceedings

From time to time we may be involved in disputes or litigation relating to claims arising out of our operations. We are not currently a party to any legal proceedings that could reasonably be expected to have a material adverse effect on our business, financial condition and results of operations.

Family Relationships

There are no family relationships among any of the directors or executive officers.

Corporate Governance

Governance Structure

Our business and affairs are organized under the direction of our board of directors, which currently consists of five members. The primary responsibilities of our board of directors are to provide oversight, strategic guidance, counseling and direction to our management. Our board of directors meets on a regular basis and on an ad hoc basis as required.

In accordance with the terms of our amended & restated certificate of incorporation and amended & restated bylaws, our board of directors will be elected annually to a three-year term.

The authorized size of our board of directors is currently five members. The authorized number of directors may be changed only by resolution of our board of directors.

Director Independence

Our board of directors has determined that four current members qualify as “independent” in accordance with the Nasdaq listing standards.

There are no family relationships among any of our directors or executive officers.

Committees of the Board of Directors

Our board has established an audit committee, a compensation committee and a nominating & corporate governance committee, each with its own charter approved by the board. Each committee’s charter is available on our website at ir.contexttherapeutics/corporate-governance/committees.

The following is a brief description of the committees.

Audit Committee

The current members of our audit committee are Richard Berman, Linda West and Jennifer Evans Stacey. Linda West serves as the chairperson of the committee. Each member of the audit committee satisfies the Nasdaq independence requirements.

Our board of directors has determined that Linda West is an audit committee financial expert as defined under the applicable rules of the SEC and has the requisite financial sophistication as defined under the applicable rules and regulations of the Nasdaq.

Under the rules of the SEC, members of the audit committee must also meet heightened independence standards. Our board of directors has determined that each of Richard Berman, Linda West and Jennifer Evans Stacey are independent under the applicable rules of the SEC and Nasdaq.

The audit committee’s primary responsibilities are to assist the board of directors in overseeing:

•the Company’s accounting and financial reporting processes and internal controls as well as the audit and integrity of the Company’s financial statements;

•the qualifications, independence and performance of the Company’s independent registered public accounting firm;

•the Company’s compliance with applicable law, including U.S. federal securities laws and other legal and regulatory requirements;

•the performance of the Company’s internal audit function; and

•the Company’s overall risk exposure and management

Both our independent registered public accounting firm and management periodically meet privately with our audit committee.

We believe that the composition and functioning of our audit committee complies with all applicable requirements of the Sarbanes-Oxley Act, and all applicable SEC and Nasdaq rules and regulations. We intend to comply with future requirements to the extent they become applicable to us.

Compensation Committee

The current members of our compensation committee are Richard Berman, Jennifer Evans Stacey, Esq. and Linda West. Mr. Berman serves as the chairperson of the committee. Each member of the compensation committee is a non-employee director, as defined in Rule 16b-3 promulgated under the Exchange Act and satisfies the Nasdaq independence requirements. The compensation committee assists the board of directors in setting the compensation of our directors and executive officers and administering and implementing our incentive compensation plans and equity-based plans. The compensation committee’s duties and responsibilities include:

•providing oversight of the compensation of our Chief Executive Officer and other executive officers;

•administering our equity compensation plans and granting equity awards pursuant to such plans or outside of such plans; and

•providing oversight of the Company’s compensation policies and plans and benefits programs and overall compensation philosophy.

Under our compensation committee charter, the compensation committee has the authority to retain compensation consultants. The compensation committee also has the authority to obtain advice and assistance from our executives, internal or external legal, accounting or other advisors as it determines necessary to carry out its duties.

The compensation committee may delegate its authority to determine the amount and form of compensation paid to our non-executive employees and consultants to officers and other appropriate supervisory personnel. It may also delegate its authority (other than its authority to determine the compensation of our Chief Executive Officer) to a subcommittee of the compensation committee. Finally, to the extent permitted by applicable law, the compensation committee may delegate to one or more officers of the Company (or other appropriate personnel) the authority to recommend stock options and other stock awards for employees who are not executive officers or members of our board of directors.

Nominating & Corporate Governance Committee

The current members of our nominating and corporate governance committee are Philip Kantoff, MD, Jennifer Evans Stacey, Esq. and Linda West. Ms. Stacey serves as the chairperson of the committee. Each of the members of our nominating and corporate governance committee is an independent director under the applicable rules and regulations of the Nasdaq relating to nominating and corporate governance committee independence. The nominating and corporate governance committee’s duties and responsibilities include:

•assisting the board of directors in identifying individuals who are qualified to become members of the board and selecting, or recommending to the board that the board select, specified individuals as director nominees;

•developing and maintaining corporate governance policies applicable to the Company; and

•overseeing evaluations of the board.

The nominating and corporate governance committee identifies director candidates based on input provided by a number of sources, including members of the committee, other directors, our stockholders, members of management and third parties. The nominating and corporate governance committee also has the authority to consult with or retain advisors or search firms to assist in the identification of qualified director candidates.

As part of the identification process, the nominating and corporate governance committee also takes into account each candidate’s business and professional skills, experience serving in management or on the board of directors of companies similar to the Company, financial literacy, independence, personal integrity and judgment. In conducting this assessment, the nominating and corporate governance committee, in connection with its assessment and recommendation of candidates for director, considers diversity (including, but not limited to, gender, race, ethnicity, age, experience and skills) and such other factors as it deems appropriate given the then-current and anticipated future needs of the board and the Company, and to maintain a balance of perspectives, qualifications, qualities and skills on the board. The board of directors does not have a formal diversity policy for directors. However, the board of directors is committed to an inclusive membership. Although the nominating and corporate governance committee may seek candidates that have different qualities and experiences at different times in order to maximize the aggregate experience, qualities and strengths of the board members, nominees for each election or appointment of directors will be evaluated using a substantially similar process.

Code of Ethics

We have adopted a code of ethics that applies to all of our directors, officers and employees, including our principal executive officer. Such code of ethics addresses, among other things, honesty and ethical conduct, conflicts of interest, compliance with laws, regulations and policies, including disclosure requirements under the federal securities laws, and reporting of violations of the code. Our code of business conduct and ethics is available under the Corporate Governance section of our website.

We are required to disclose any amendment to, or waiver from, a provision of our code of ethics applicable to our principal executive officer, principal financial officer, principal accounting officer, controller, or persons performing similar functions. We intend to use our website as a method of disseminating this disclosure, as permitted by applicable SEC rules. Any such disclosure will be posted to our website within four business days following the date of any such amendment to, or waiver from, a provision of our code of ethics.

Limitation of Liability and Indemnification

Our amended & restated certificate of incorporation limits the liability of our directors to the maximum extent permitted by Delaware law. Delaware law provides that directors of a corporation will not be personally liable for monetary damages for breach of their fiduciary duties as directors, except liability for:

•any breach of their duty of loyalty to the corporation or its stockholders;

•acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;

101

•unlawful payments of dividends or unlawful stock repurchases or redemptions; or

•any transaction from which the director derived an improper personal benefit.

Our amended & restated certificate of incorporation and amended & restated bylaws provide for the indemnification of our directors and officers to the fullest extent permitted under the Delaware General Corporation Law (“DGCL”). In addition, the amended & restated certificate of incorporation provides that our directors shall not be personally liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director and that if the DGCL is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of our directors shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended.

As permitted by the DGCL, we have entered into or plan to enter into separate indemnification agreements with each of our directors and certain of our officers that require us, among other things, to indemnify them against certain liabilities which may arise by reason of their status as directors, officers or certain other employees. We maintain insurance policies under which our directors and officers are insured, within the limits and subject to the limitations of those policies, against certain expenses in connection with the defense of, and certain liabilities that might be imposed as a result of, actions, suits or proceedings to which they are parties by reason of being or having been directors or officers. The coverage provided by these policies may apply whether or not we would have the power to indemnify such person against such liability under the provisions of the DGCL.

We believe that these provisions and agreements are necessary to attract and retain qualified persons as our officers and directors. At present, there is no pending litigation or proceeding involving our directors or officers for which indemnification is required or permitted, and we are not aware of any threatened litigation or proceeding that may result in a claim for indemnification.

The limitation of liability and indemnification provisions contained in our amended & restated certificate of incorporation and our amended & restated bylaws may discourage stockholders from bringing a lawsuit against our directors for breach of their fiduciary duty. They may also reduce the likelihood of derivative litigation against our directors and officers, even though an action, if successful, might benefit us and other stockholders. Further, a stockholder’s investment may be adversely affected to the extent that we pay the costs of settlement and damage awards against directors and officers as required by these indemnification provisions.

102

EXECUTIVE COMPENSATION

Exercise of Options: Options will vest and be exercisable at such time or times and subject to such terms and conditions as determined by the Management Committee.

2021 Long-Term Performance Incentive Plan

The following is a summary of certain significant features of the Context Therapeutics Inc. 2021 Long-Term Performance Incentive Plan (the “2021 Incentive Plan”). The information that follows is subject to, and qualified in its entirety by reference to, the Plan document itself, which is filed as an exhibit to the registration statement of which this prospectus forms a part. Awards that may be granted include stock options, stock appreciation rights, restricted stock, restricted stock units and stock grants. These awards are described in more detail below. The Company has reserved 1,266,092 shares of common stock (the “Share Limit”) for issuance under the 2021 Incentive Plan. The Share Limit will automatically increase on January 1st of each year, during the term of the 2021 Incentive Plan, commencing on January 1 of the year following the year in which the effective date occurs, in an amount equal to four percent (4%) of the total number of shares of the Company’s common stock outstanding on December 31st of the preceding calendar year; provided that the Board may determine that there will be no such increase or a smaller increase for any particular year. The Share Limit is subject to adjustment for certain changes in the Company’s capitalization such as stock dividends, stock splits, combinations or similar events. If an award expires, terminates, is forfeited or cancelled, or is settled in cash rather than common stock, the common stock not issued under that award will again become available for grant under the 2021 Incentive Plan. If common stock is surrendered to the Company or withheld to pay any exercise price or tax withholding requirements, only the shares issued net of the shares withheld or surrendered will be counted against the number of shares of common stock available under the 2021 Incentive Plan.

Purpose of Plan: The Plan is intended to enable the Company to (i) provide incentives and awards to employees, nonemployee directors and consultants of the Company, (ii) enable the Company to attract and retain employees, nonemployee directors and consultants, and (iii) encourage employees, nonemployee directors and consultants to acquire a proprietary interest in the performance of the Company.

Administration of the Plan: The Compensation Committee of the Company has the authority to administer the 2021 Incentive Plan. The Compensation Committee has considerable discretion in setting the terms of awards granted under the Plan. The Compensation Committee may also establish another committee of the Board of Directors (such as a committee of which the Chairman of the Board is the sole member) to make awards to employees who are not subject to Section 16(b) of the Securities Exchange Act of 1934, as amended.

Eligible Recipients: Eligible recipients include employees, nonemployee directors and consultants of the Company. Nonemployee directors and consultants are not eligible to receive incentive stock options. The Compensation Committee selects the employees, non-employee directors and consultants who will receive awards under the 2021 Incentive Plan.

Stock Options

General: A stock option under the 2021 Incentive Plan may be granted as an incentive stock option or as a nonqualified stock option in the discretion of the Compensation Committee. Incentive stock options offer employees certain tax advantages that are not available for nonqualified stock options. The Compensation Committee determines the terms and conditions of the options, including the number of shares of common stock subject to the option.

107

Price: The exercise price per share of the Company’s common stock purchasable under a stock option shall not be less than one hundred percent of the fair market value of such stock on the date the stock option is granted. With respect to an incentive stock option granted to a more than 10% stockholder of the Company, the per share exercise price may not be less than 110% of the fair market value of a share of Common Stock on the date the stock option is granted.

Exercise: Stock options will vest and be exercisable at such time or times and subject to such terms and conditions as determined by the Compensation Committee. An optionee may pay the exercise price of an option in cash or its equivalent. The Compensation Committee may also permit an optionee to pay the exercise price by surrendering previously acquired shares of common stock, withholding shares issuable upon exercise of the option, through a so-called “broker-financed transaction,” or in any combination of such methods. The 2021 Incentive Plan permits an employee to pay the tax withholding obligation with shares of common stock issuable upon the exercise of the option or previously acquired shares.

Expiration or Termination: The term of each stock option will be fixed by the Compensation Committee; provided that no option shall have a term of more than ten years (five years for an incentive stock option granted to a more than 10% stockholder). No stock option may be exercised by any person after expiration of the term of the stock option. When an optionee terminates service with the Company, his or her stock option may expire before the end of the otherwise applicable option term. For example, upon a termination of service due to the optionee’s disability, options generally remain exercisable for the full option term, and upon a termination service due to the optionee’s death, options generally remain exercisable for up to three years. If an optionee has a termination of service for cause, his or her stock options will be terminated. The Compensation Committee has the discretion to determine the exercise period after termination of service for other reasons.

Stock Appreciation Rights:

General. A stock appreciation right may be granted to eligible participants under the 2021 Incentive Plan at the discretion of the Compensation Committee, which may at the time of such grant approve. The Compensation Committee determines the terms and conditions of stock appreciation rights.

Payment. A stock appreciation right entitles a recipient to receive, with respect to each share of the Company’s common stock to which the stock appreciation right is exercised, the excess, if any, of the fair market value of the share on the date of exercise over the fair market value of the share on the date the stock appreciation right is granted. Such excess may be paid in cash, shares of the Company’s common stock, or a combination thereof, as determined by the Compensation Committee.

Exercise. Stock appreciation rights will be exercisable at such time or times and subject to such terms and conditions as determined by the Compensation Committee.

Expiration or Termination. The term of each stock appreciation right will be fixed by the Compensation Committee; provided that no stock appreciation right shall have a term of more than ten years. No stock appreciation right may be exercised by any person after expiration of the term of the stock option. When an employee, non-employee director or consultant terminates service, his or her stock appreciation rights may expire before the end of the otherwise applicable stock appreciation right term. The period during which the stock appreciation right may be exercised is the same as the period for stock options, discussed above.

Restricted Stock:

Restricted stock may be granted by the Compensation Committee to eligible participants for no consideration in the form of an award of common stock subject to restrictions. At the time restricted stock is granted, the Compensation Committee shall determine whether the restricted stock is performance stock (where the lapse of restrictions is based on performance targets), or restricted stock that is not performance stock (where the lapse of restrictions is based on times and/or conditions determined by the Compensation Committee). The Company holds the common stock during the restriction period and the participant cannot transfer the shares before the end of that period. The participant is, however, generally entitled to vote the common stock and receive any cash dividends declared and paid on common stock of the Company during the restriction period.

108

For performance stock awards, the restrictions lapse only to the extent performance goals established by the Compensation Committee are met. The Compensation Committee may select one or more performance criteria for each performance stock award from the following list: profit before taxes, earnings before or after taxes, interest, depreciation and/or amortization, stock price, market share, gross revenue, net revenue, pre-tax income, operating income, cash flow, earnings per share, return on equity, return on invested capital or assets, cost reductions and savings, return on revenues or productivity, or any variations of the preceding business criteria. The criteria may be applied to the individual, a division, a regional business unit, the Company or a subsidiary of the Company. Additional business criteria on which an individual’s performance may be measured are implementing policies and plans, negotiating transactions and sales, developing long-term business goals and exercising managerial responsibility.

The restrictions lapse for restricted stock awards that are not performance stock awards on the earliest of the date or event determined by the Compensation Committee.

Restricted Stock Units:

A restricted stock unit entitles a recipient to receive one share of the Company’s common stock, cash equal to the fair market value of a share of the Company’s common stock on the date of vesting, or a combination thereof, with respect to each restricted stock unit that vests in accordance with the award of such restricted stock unit. A bookkeeping account is established for each recipient of a restricted stock unit award that shows the number of restricted stock units granted, and may include full and fractional restricted stock units representing any cash dividends prior to the date the restricted stock unit vests. Performance stock units vest only to the extent performance goals established by the Compensation Committee are met. The Compensation Committee may select one or more performance criteria for each award of performance stock units from the above list for performance stock awards. Restricted stock units that are not performance stock units vest on the date or event determined by the Compensation Committee.

Stock Grants:

The Compensation Committee may make grants of unrestricted common stock to eligible recipients. Such stock grants shall be fully vested on the date granted.

Miscellaneous

Transferability. Awards generally are not transferable, except by will or under the laws of descent and distribution. The Compensation Committee has the authority to the extent permitted under the Code, however, to permit an employee, non-employee director or consultant to transfer non-qualified stock options, restricted stock, restricted stock units and stock appreciation rights to certain permitted transferees.

Acceleration of Vesting. All awards (other than performance-based awards) vest on a pro-rata basis (based on active service during the applicable vesting period) upon a termination due to death or disability. The Compensation Committee may, in its discretion, provide for the acceleration or continuation of the vesting of all awards (other than performance-based awards) following termination of service, if it determines that to do so would be in the best interests of the Company. Upon a change in control of the Company (as defined in the 2021 Incentive Plan), to the extent that the Awards are not assumed by the acquiring or succeeding corporation, all outstanding options and stock appreciation rights become exercisable, all outstanding restricted stock becomes vested, and all outstanding restricted stock units become vested.

Change in Capitalization/Certain Corporate Transactions. If there is a change in the capitalization of the Company that affects its outstanding common stock, the Compensation Committee will adjust the kind and aggregate number of shares of common stock subject to awards, together with the option exercise price and amount over which appreciation of stock appreciation rights is measured. The 2021 Incentive Plan also provides that, in the event of a merger, consolidation or other specified corporate transaction, with respect to awards that will not be assumed or substituted, the Compensation Committee may (i) terminate outstanding awards after providing notice to holders specifying a period of time by which they may exercise their options or (ii) terminate outstanding awards and pay to the holders the value of such awards based upon the price per share of stock received or to be received by

109

other stockholders of the Company in the event (except that underwater options and stock appreciation rights would receive no payment) or replace the award with rights or property selected by the Compensation Committee in its sole discretion.

Amendment/Termination. The Compensation Committee may amend outstanding awards, and the Board of Directors may amend or suspend the 2021 Incentive Plan. However, stockholder approval is required for (1) any material amendment to the 2021 Incentive Plan (as defined under applicable NASDAQ Listing Standards), (2) an amendment to “reprice” an outstanding option or stock appreciation right, and (3) certain amendments of which the 2021 Incentive Plan requires stockholder approval, such as an increase in the number of shares of common stock authorized for issuance of incentive stock options and a change in the class of employees who may receive incentive stock options under the 2021 Incentive Plan.

The Board of Directors may terminate the 2021 Incentive Plan at any time and for any reason. No awards will be granted under the 2021 Incentive Plan after the close of business on the day immediately preceding the tenth anniversary of the effective date of the 2021 Incentive Plan or any earlier termination date determined by the Board.

Clawback. A participant’s right to receive an award, to retain amounts payable under the award, and to retain any profit or gain associated with a non-cash award are all subject to any recoupment or “clawback” policy adopted by the Company.

Registration under the Securities Act of 1933. The Company filed with the Securities and Exchange Commission a Registration Statement on Form S-8 to register the shares of the Company’s common stock subject to the 2021 Incentive Plan.

Indemnification Agreements. We have entered into or plan to enter into indemnification agreements with each of our directors and executive officers. The indemnification agreements and our amended & restated certificate of incorporation and amended & restated bylaws will require us to indemnify our directors and executive officers to the fullest extent permitted by Delaware law.

Federal Income Tax Consequences – Options. We have been advised that the Federal income tax consequences of granting and exercising options under the 2021 Incentive Plan are as follows (based on Federal tax laws and regulations, as of January 1, 2021). The grant of an option does not result in Federal income tax consequences for the optionee or a deduction for the Company.

When an option is exercised, the Federal income tax consequences depend on whether the option is an incentive stock option or a non-qualified stock option. An optionee exercising a non-qualified stock option will recognize ordinary income equal to the difference between the fair market value of the stock exercised (on the date of exercise) and the exercise price. An employee will generally not recognize taxable income as a result of acquiring stock by exercising an incentive stock option. If the employee holds the stock he receives on exercise of an incentive stock option for a required period of time, the employee will have capital gain (or loss) when the stock is later disposed of. If the employee does not hold the stock for the required period of time, the employee will generally have ordinary income when the stock is disposed of. When an optionee recognizes ordinary income on the exercise of a non-qualified stock option or the sale of stock acquired on exercise of an incentive stock option, the Company is generally entitled to a deduction in the same amount.

PRINCIPAL STOCKHOLDERS

The following table sets forth certain information with respect to the beneficial ownership of our common stock as of December 6, 2021, by:

•each of our named executive officers and directors;

•all of our named executive officers and directors as a group; and

•each other stockholder known by us to be the beneficial owner of more than 5% of the outstanding shares of our voting stock.

We have determined beneficial ownership in accordance with the rules of the SEC. Except as indicated by the footnotes below, we believe, based on the information furnished to us, that the persons and entities named in the table below have sole voting and investment power with respect to all shares that they beneficially own, subject to applicable community property laws. Unless otherwise indicated in the footnotes below, based on the information provided to us by or on behalf of the selling stockholders, no selling stockholder is a broker-dealer or an affiliate of a broker-dealer.

Percentage ownership of our common stock is based on 15,966,053 shares of common stock outstanding as of December 6, 2021.

In computing the number of shares of common stock beneficially owned by a person and the percentage ownership of that person, we deemed to be outstanding all shares of common stock subject to options or other convertible securities held by that person or entity that are currently exercisable or releasable or that will become exercisable or releasable only by such person within 60 days of December 6, 2021, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other person.

To calculate a stockholder’s percentage of beneficial ownership of common stock, we must include in the numerator and denominator those shares of common stock, as well as those shares of common stock underlying options or other convertible securities, that such stockholder is considered to beneficially own. Shares of common stock, and common stock underlying options and other convertible securities, held by other stockholders, however, are disregarded in this calculation. Therefore, the denominator used in calculating beneficial ownership of each of the stockholders may be different.

Unless otherwise indicated, the address of each beneficial owner listed in the table below is c/o the Company, 3675 Market Street, Suite 200 Philadelphia, Pennsylvania 19104. To our knowledge, there is no arrangement, including any pledge by any person of securities of the Company, the operation of which may at a subsequent date result in a change in control of the Company.

Junior Convertible Note

From inception through December 2018, the Company issued Junior Convertible Notes that had a fair value of $15.8 million and bore interest at rates ranging from 3.00% to 7.73% per year. From January 2019 to April 2019, the Company issued Junior Convertible Notes in the aggregate principal amount of $1.5 million that bore interest at rates ranging between 6.00% and 15.00% per year. From April 2015 through December 2017, the Company issued demand notes to the Company’s Chief Executive Officer and an immediate family member (the “Related Party”) with an aggregate principal balance of $1.8 million that bore interest at rates ranging from 3.00% to 6.00% per year. During April 2019, $1.9 million of principal and interest was converted from demand notes to a Junior Convertible Note bearing interest at a rate of 15.00%. Additionally, in July 2019, the Company issued $1.2 million of Junior Convertible Notes in lieu of severance payments to former executives, of which $0.9 million and $0.3 million were expensed to general and administrative and research and development expense, respectively, during the year ended December 31, 2019. On December 31, 2019, $5.7 million of Junior Convertible Notes outstanding were held by the Related Party. The Junior Convertible Notes outstanding principal amount of $10.2 million and accrued but unpaid interest of $1.5 million converted into 2,615,553 Series Seed Convertible Preferred Units (the “Series Seed Units”) in May 2020, of which 840,363 were issued to the Related Party.

Convertible Bridge Notes

From October 2019 to March 2020, the Company issued convertible bridge notes (the “Convertible Bridge Notes”) to the Related Party in the amount of $0.5 million. The Convertible Bridge Notes bore interest at a rate of 6.0% per annum and on December 22, 2020, the outstanding principal and accrued interest of $35,000 converted into 78,178 Series A Units that were issued to the Related Party.

Senior Convertible Note

Series A Preferred Units and Series Seed Preferred Units

In May 2020, the Company converted $11.7 million of principal and interest related to certain Junior Convertible Notes into 2,615,553 Series Seed Units at prices ranging from $4.28 to $4.56 per unit. In May 2020, the Related Party purchased 8,771 Series Seed Units at a price of $5.70 per unit for $50,000.

Throughout 2020 the Company sold 132,537 Series A Units to the Related Party for $7.168 per unit for proceeds of $1.0 million. The Company also issued 52,673 warrants to purchase common member units (the “Common Member Units”) at an exercise price of $7.168 to the holders of Series A Units as part of the Series A financing.

115

The following is a summary of certain terms of the Series A Units and Series Seed Units (collectively, “Convertible Preferred Units”):

Distribution

Holders of Series A Units received a non-cumulative distribution of 6% per year of the original capital contribution, which was payable upon the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company (“Dissolution Event”), or the redemption or repurchase of any Series A Units. Series Seed Units did not receive a distribution right.

Liquidation

Upon a Dissolution Event, the holders of Series A Units would have received the greater of 1.5 times the original issuance price plus any accrued distributions or the amount that such holders of Series A Units would receive if the Series A Units were converted to Common Member Units, prior to any distribution with respect to Series Seed Units or Common Member Units.

After amounts paid out to the Series A Units upon a Dissolution Event, the Series Seed Units then outstanding would have been entitled to be paid out in accordance with the positive balance in their capital accounts with respect to their Series Seed Units, after giving effect to all contributions, distributions and allocations with respect to such Series Seed Units for all periods, before any payment shall be made to the holders of Common Member Units.

Conversion rights

Each Convertible Preferred Unit was convertible, at the option of the holder thereof, at any time, and without the payment of additional consideration, into a number of fully paid and nonassessable common member units as determined by dividing the original issue price for the Convertible Preferred Unit by the conversion price for the Convertible Preferred Unit in effect at the time of conversion, except as otherwise defined in the Operating Agreement (the “Operating Agreement”). Notwithstanding the foregoing, in the event of a liquidation, dissolution, or winding up of the Company or acquisition of the majority of the Company’s assets, the Series Seed Unit conversion right would have terminated at the close of business on the last full day preceding the date fixed for the first payment of any funds and assets distributable on such event to the Members holding Series Seed Units. No fractional Common Member Units would have been issued upon conversion of the Convertible Preferred Unit. In lieu of any fractional units, the Company would have paid cash equal to such fraction multiplied by the fair market value of a Common Member Unit as determined in good faith by the Management Committee of the Company.

Warrants for Common Member Units

Since inception, the Company has granted warrants to the Related Party to purchase Common Member Units at various dates. At December 31, 2020, the Company had the following warrants outstanding to acquire Common Member Units:


Issue Date	Outstanding	Exercise Price		Expiration Dates
2020	52,680	$	7.17	December 2025
2019	13,281	$	4.56	April 2039

DESCRIPTION OF CAPITAL STOCK

General

The following description of our capital stock and certain provisions of our amended & restated certificate of incorporation and amended & restated bylaws are summaries. Copies of these documents are filed with the SEC as exhibits to our registration statement, of which this prospectus forms a part.

Our authorized capital stock consists of 100,000,000 shares of common stock, par value $0.001 per share and 10,000,000 shares of preferred stock, par value $0.001 per share. As of December 1, 2021, 10,966,053 shares of our common stock were outstanding, and no shares of our preferred stock were outstanding. Following the completion of the Private Placement, 15,966,053 shares of our common stock were outstanding and no shares of our preferred stock were outstanding.

Common Stock

We are authorized to issue one class of common stock. Holders of our common stock are entitled to one vote for each share of common stock held of record for the election of directors and on all matters submitted to a vote of stockholders. A majority vote of the holders of common stock will generally required to take action under our amended & restated certificate of incorporation and amended & restated bylaws. Holders of our common stock are entitled to receive dividends ratably, if any, as may be declared by our board of directors out of legally available funds, subject to any preferential dividend rights of any preferred stock then outstanding. Upon our dissolution, liquidation or winding up, holders of our common stock are entitled to share ratably in our net assets legally available after the payment of all our debts and other liabilities, subject to the preferential rights of any preferred stock then outstanding. Holders of our common stock have no preemptive, subscription, redemption or conversion rights and no sinking fund provisions are applicable to our common stock. The rights, preferences and privileges of holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future.

Preferred Stock

Our board of directors has the authority, without further action by the stockholders, to issue up to 10,000,000 shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof. These rights, preferences and privileges could include dividend rights, conversion rights, voting rights, redemption rights, liquidation preferences, sinking fund terms and the number of shares constituting any series or the designation of such series, any or all of which may be greater than the rights of our common stock. The issuance of preferred stock could adversely affect the voting power of holders of our common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation. In addition, the issuance of preferred stock could have the effect of delaying, deferring or preventing change in our control or other corporate action.

Our board of directors will make any determination to issue shares of preferred stock based on its judgment as to the best interests of the Company and the best interests of our stockholders. We have no shares of preferred stock currently outstanding and we have no current plans to issue any shares of preferred stock.

Anti-Takeover Effects of Provisions of Our Amended & Restated Certificate of Incorporation, Amended & Restated Bylaws and Delaware Law

Some provisions of Delaware law and our amended & restated certificate of incorporation and our amended & restated bylaws contain provisions that could make the following transactions more difficult: acquisition of us by means of a tender offer; acquisition of us by means of a proxy contest or otherwise; or removal of our incumbent officers and directors. It is possible that these provisions could make it more difficult to accomplish or could deter transactions that stockholders may otherwise consider to be in their best interest or in our best interests, including transactions that might result in a premium over the market price for our shares.

118

These provisions, summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that the benefits of increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging these proposals because negotiation of these proposals could result in an improvement of their terms.

Delaware Takeover Statute

We are subject to the provisions of Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a three-year period following the time that this stockholder becomes an interested stockholder, unless the business combination is approved in a prescribed manner. Under Section 203, a business combination between a corporation and an interested stockholder is prohibited unless it satisfies one of the following conditions:

•before the stockholder became interested, our board of directors approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

•upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding, shares owned by persons who are directors and also officers, and employee stock plans, in some instances, but not the outstanding voting stock owned by the interested stockholder; or

•at or after the time the stockholder became interested, the business combination was approved by our board of directors and authorized at an annual or special meeting of the stockholders by the affirmative vote of at least two-thirds of the outstanding voting stock which is not owned by the interested stockholder.

Section 203 defines a business combination to include:

•any merger or consolidation involving the corporation and the interested stockholder;

•any sale, transfer, lease, pledge or other disposition involving the interested stockholder of 10% or more of the assets of the corporation;

•subject to exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;

•subject to exceptions, any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or series of the corporation beneficially owned by the interested stockholder; and

•the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.

In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by the entity or person.

No Written Consent of Stockholders

Our amended & restated certificate of incorporation provides that all stockholder actions are required to be taken by a vote of the stockholders at an annual or special meeting, and that stockholders may not take any action by written consent in lieu of a meeting. This limit may lengthen the amount of time required to take stockholder actions and would prevent the amendment of our amended and restated bylaws or removal of directors by our stockholders without holding a meeting of stockholders.

119

Meetings of Stockholders

Our amended & restated bylaws provides that a special meeting of stockholders may be called only by our chairman of the board of directors, Chief Executive Officer or by a resolution adopted by a majority of our board of directors, and only those matters set forth in the notice of the special meeting may be considered or acted upon at a special meeting of stockholders. Our amended and restated bylaws also limits the business that may be conducted at an annual meeting of stockholders to those matters properly brought before the meeting.

Advance Notice Requirements

Our amended & restated bylaws establishes advance notice procedures with regard to stockholder proposals relating to the nomination of candidates for election as directors or new business to be brought before meetings of our stockholders. These procedures provide that notice of stockholder proposals must be timely given in writing to our corporate secretary prior to the meeting at which the action is to be taken. Generally, to be timely, notice must be received at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary date of the annual meeting for the preceding year. Our amended and restated bylaws specifies the requirements as to form and content of all stockholders’ notices. These requirements may preclude stockholders from bringing matters before the stockholders at an annual or special meeting.

Amendment to Our Certificate of Incorporation

Any amendment of our certificate of incorporation must first be approved by a majority of our board of directors, and if required by law or our certificate of incorporation, must thereafter be approved by a majority of the outstanding shares entitled to vote on the amendment.

Undesignated Preferred Stock

Our amended & restated certificate of incorporation provides for 10,000,000 authorized shares of preferred stock. The existence of authorized but unissued shares of preferred stock may enable our board of directors to discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise. For example, if in the due exercise of its fiduciary obligations, our board of directors were to determine that a takeover proposal is not in the best interests of our stockholders, our board of directors could cause shares of preferred stock to be issued without stockholder approval in one or more private offerings or other transactions that might dilute the voting or other rights of the proposed acquirer or insurgent stockholder or stockholder group. In this regard, our amended and restated certificate of incorporation grants our board of directors broad power to establish the rights and preferences of authorized and unissued shares of preferred stock. The issuance of shares of preferred stock could decrease the amount of earnings and assets available for distribution to holders of shares of common stock. The issuance may also adversely affect the rights and powers, including voting rights, of these holders and may have the effect of delaying, deterring or preventing a change in control of us.

Choice of Forum

120

provides that any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock will be deemed to have notice of and to have consented to these choice of forum provisions. It is possible that a court of law could rule that the choice of forum provisions contained in our amended & restated certificate of incorporation are inapplicable or unenforceable if they are challenged in a proceeding or otherwise. Although we believe these provisions benefit us by providing increased consistency in the application of Delaware law and the Securities Act for the specified types of actions and proceedings, the provisions may have the effect of discouraging lawsuits against us or our directors and officers.

Warrants for Common Stock

Since inception, in addition to the warrants issued in connection with the Private Placement, the Company has granted warrants to purchase shares of common stock at various dates. At December 6, 2021, the Company had the following warrants outstanding to acquire shares of common stock:

121

SHARES ELIGIBLE FOR FUTURE SALE

As of December 1, 2021 we have 10,966,053 shares of common stock outstanding, all of which will be freely transferable without restriction under the Securities Act unless purchased by one of our affiliates as that term is defined in Rule 144 under the Securities Act, which generally includes directors, executive officers and 10% stockholders, or are subject to lock-up agreements. Sales of substantial amounts of our shares in the public market could adversely affect prevailing market prices of our shares.

As a result of the lock-up agreements referred to below and the provisions of Rule 144 and Rule 701 under the Securities Act, based on the number of shares of our common stock outstanding as of December 1, 2021, the remaining shares of our common stock will generally become available for sale in the public market as follows:


Approximate Number of Shares						First Date Available for Sale on the Public Markets
5,216,053 shares						366 days after October 19, 2021, in the case of our officers and directors, and 181 days after October 19, 2021, in the case of our pre-IPO stockholders, upon expiration of the lock-up agreements referred to below, subject in some cases to applicable volume, manner of sale and other limitations under Rule 144 and Rule 701.

We may issue shares of common stock from time to time as consideration for future acquisitions, investments or other corporate purposes.

In the event that any such acquisition, investment or other transaction is significant, the number of shares of common stock that we may issue may in turn be significant. We may also grant registration rights covering those shares of common stock issued in connection with any such acquisition and investment. In addition, the shares of common stock reserved for future issuance under our 2021 Incentive Plan will become eligible for sale in the public market to the extent permitted by the provisions of various vesting schedules, the lock-up agreements, a registration statement under the Securities Act or an exemption from registration, including Rule 144 and Rule 701.

Rule 144

In general, under Rule 144 of the Securities Act, a person or entity that has beneficially owned our common stock for at least six months and is not our “affiliate” will be entitled to sell our common stock, subject only to the availability of current public information about us, and will be entitled to sell shares held for at least one year without any restriction. A person or entity that is our “affiliate” and has beneficially owned our common stock for at least six months will be able to sell, within a rolling three month period, the number of shares that does not exceed the greater of the following:

(i)1% of the then outstanding common stock, which immediately after this offering will equal approximately 159,660 shares of common stock; and

(ii)the average weekly trading volume of our common stock on Nasdaq during the four calendar weeks preceding the date on which notice of the sale is filed with the SEC.

Sales by affiliates under Rule 144 must be made through unsolicited brokers’ transactions. They are also subject to manner of sale provisions, notice requirements and the availability of current public information about us.

Rule 701

In general, under Rule 701 of the Securities Act as currently in effect, each of our employees, directors or consultants who purchases our common stock from us pursuant to a compensatory stock or option plan or other written agreement relating to compensation is eligible to resell such common stock 90 days after we become a reporting company under the Exchange Act in reliance on Rule 144, but without compliance with some of the restrictions, such as the holding period, contained in Rule 144. However, the Rule 701 shares would remain subject to lock-up arrangements and would only become eligible for sale when the lock-up period expires.

122

Lock-Up Agreements

In connection with our initial public offering, we, along with our directors, executive officers and substantially all of our other stockholders, have agreed with the underwriter that for the period from the date of the lock-up agreement continuing through 365 days from October 19, 2021, in the case of our executive officers and directors, and 180 days from October 19, 2021, in the case of our stockholders who held stock in the Company prior to our initial public offering and us, will not sell, offer to sell, contract to sell or lend, effect any short sale or establish or increase any put equivalent position or liquidate or decrease any call equivalent position, pledge, hypothecate, grant any security interest in or in any other way transfer or dispose of, directly or indirectly, any shares of our common stock or any securities convertible into or exchangeable for shares of common stock, or enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the common stock.

After our initial public offering, certain of our employees, including our executive officers and/or directors may enter into written trading plans that are intended to comply with Rule 10b5-1 under the Exchange Act. Sales under these trading plans would not be permitted until the expiration of the lock-up agreements relating to the offering described above.

Additionally, in connection with the Private Placement, our officers and directors have agreed, subject to certain exceptions, with the placement agent in such Private Placement not to directly or indirectly offer, sell, contract to sell, pledge or otherwise dispose of any shares of our common stock or any securities convertible into or exchangeable for shares of common stock during the 60-day period starting on December 1, 2021, except with the prior written consent of the placement agent.

Equity Incentive Plans

On October 20, 2021, we filed with the SEC a registration statement on Form S-8 under the Securities Act covering the shares of common stock reserved for issuance under our 2021 Incentive Plan. Accordingly, shares registered under the registration statement became available for sale in the open market following its effective date, subject to vesting restrictions, Rule 144 volume limitations and the lock-up agreements described above, if applicable.

123

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES TO NON-U.S. HOLDERS OF THE COMPANY’S COMMON STOCK

The following is a summary of the material U.S. federal income tax consequences to non-U.S. holders (as defined below) of the purchase, ownership and disposition of the Company’s common stock included in this offering, but does not purport to be a complete analysis of all the potential tax considerations relating thereto. This summary is based upon the provisions of the Internal Revenue Code of 1986, as amended, or the Internal Revenue Code, Treasury regulations promulgated thereunder, published administrative rulings and judicial decisions, all as of the date hereof. These authorities may be changed or be subject to differing interpretations, possibly retroactively, so as to result in U.S. federal income tax consequences different from those set forth below. No ruling on the U.S. federal, state, local or other tax considerations relevant to the Company’s operations or to the purchase, ownership or disposition of its shares, has been requested from the U.S. Internal Revenue Service, or the IRS, or other tax authority. No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of the tax consequences described below.

This summary also does not address the tax considerations arising under any U.S. federal tax laws other than income tax laws, the laws of any non-U.S., state or local jurisdiction, or under U.S. federal gift and estate tax laws. In addition, this summary does not address U.S. federal income tax considerations applicable to a non-U.S. holder’s particular circumstances or to non-U.S. holders that may be subject to special tax rules, including, without limitation:

•banks, insurance companies or other financial institutions, regulated investment companies or real estate investment trusts;

•persons subject to the alternative minimum tax or Medicare contribution tax on net investment income;

•tax-exempt organizations or governmental organizations;

•tax-qualified retirement plans;

•“controlled foreign corporations,” “passive foreign investment companies” and corporations that accumulate earnings to avoid U.S. federal income tax;

•brokers or dealers in securities or currencies;

•traders in securities that elect to use a mark-to-market method of accounting for their securities holdings;

•persons that own, or are deemed to own, more than five percent of the Company’s capital stock (except to the extent specifically set forth below);

•U.S. expatriates and former citizens or long-term residents of the United States;

•partnerships or entities classified as partnerships for U.S. federal income tax purposes or other pass-through entities (and investors therein);

•persons who hold the Company’s common stock as a position in a hedging transaction, “straddle,” “conversion transaction” or other risk reduction transaction or integrated investment;

•“qualified foreign pension funds” as defined in Section 897(l)(2) of the Internal Revenue Code and entities all of the interests of which are held by qualified foreign pension funds;

•persons subject to special tax accounting rules as a result of any item of gross income with respect to common stock being taken into account in an applicable financial statement;

•persons who hold or receive the Company’s common stock pursuant to the exercise of any employee stock option or otherwise as compensation;

124

•persons who do not hold the Company’s common stock as a capital asset within the meaning of Section 1221 of the Internal Revenue Code; or

•persons deemed to sell the Company’s common stock under the constructive sale provisions of the Internal Revenue Code.

In addition, if a partnership or entity classified as a partnership for U.S. federal income tax purposes holds the Company’s common stock, the tax treatment of a partner generally will depend on the status of the partner, the activities of the partnership, and certain determinations made at the partner level. Accordingly, partnerships that hold the Company’s common stock, and partners in such partnerships, should consult their tax advisors.

This discussion is for informational purposes only and is not tax advice. You are urged to consult your tax advisor with respect to the application of the U.S. federal income tax laws to your particular situation, as well as any tax consequences of the purchase, ownership and disposition of the Company’s common stock arising under the U.S. federal estate or gift tax rules or under the laws of any state, local, non-U.S., or other taxing jurisdiction or under any applicable tax treaty.

Non-U.S. Holder Defined For purposes of this discussion, you are a non-U.S. holder (other than a partnership) if you are a beneficial owner of the Company’s common stock other than:

•an individual citizen or resident of the United States (for U.S. federal income tax purposes);

•a corporation or other entity taxable as a corporation created or organized in the United States or under the laws of the United States, any state thereof, or the District of Columbia, or other entity treated as such for U.S. federal income tax purposes;

•an estate whose income is subject to U.S. federal income tax regardless of its source; or

•a trust (x) whose administration is subject to the primary supervision of a U.S. court and which has one or more “U.S. persons” (within the meaning of Section 7701(a)(30) of the Internal Revenue Code) who have the authority to control all substantial decisions of the trust or (y) which has made a valid election to be treated as a U.S. person for U.S. federal income tax purposes.

Distributions

As described in the section entitled “Dividend Policy,” the Company has never declared or paid cash dividends on its common stock and does not anticipate paying any dividends on its common stock in the foreseeable future. However, if the Company does make distributions of cash or property on its common stock, those payments will constitute dividends for U.S. tax purposes to the extent paid from the Company’s current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent those distributions exceed both the Company’s current and its accumulated earnings and profits, they will constitute a return of capital and will first reduce your basis in the Company’s common stock, but not below zero, and then will be treated as gain from the sale of stock as described below under “—Gain on the Sale or Other Taxable Disposition of Common Stock.”

Subject to the discussion below on effectively connected income, backup withholding and foreign accounts, any dividend paid to you generally will be subject to U.S. withholding tax either at a rate of 30% of the gross amount of the dividend or such lower rate as may be specified by an applicable income tax treaty. In order to receive a reduced treaty rate, you must timely provide us or the applicable withholding agent with a valid IRS Form W-8BEN, IRS Form W-8BEN-E, or other appropriate version of IRS Form W-8 or applicable certifying qualification for the reduced rate. A non-U.S. holder of shares of the Company’s common stock eligible for a reduced rate of U.S. withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. If the non-U.S. holder holds the stock through a financial institution or other agent acting on the non-U.S. holder’s behalf, the non-U.S. holder will be required to provide appropriate documentation to the agent, which then will be required to provide certification to the Company or its paying agent, either directly or through other intermediaries.

125

Dividends received by you that are effectively connected with your conduct of a U.S. trade or business (and, if required by an applicable income tax treaty, attributable to a permanent establishment maintained by you in the United States) are generally exempt from the withholding tax described above. In order to obtain this exemption, you must provide us or the applicable withholding agent with a valid IRS Form W-8ECI or other applicable IRS Form W-8 properly certifying such exemption. Such effectively connected dividends, although not subject to U.S. federal income withholding tax, are taxed for U.S. federal income tax purposes at the same graduated rates applicable to U.S. persons, net of certain deductions and credits. In addition, if you are a corporate non-U.S. holder, dividends you receive that are effectively connected with your conduct of a U.S. trade or business may also be subject to a branch profits tax at a rate of 30% or such lower rate as may be specified by an applicable income tax treaty. You should consult your tax advisor regarding any applicable tax treaties that may provide for different rules.

Gain on the Sale or other Taxable Disposition of Common Stock

Subject to the discussion below regarding information reporting, backup withholding and foreign accounts, you generally will not be required to pay U.S. federal income tax on any gain realized upon the sale or other taxable disposition of the Company’s common stock unless:

•the gain is effectively connected with your conduct of a U.S. trade or business (and, if required by an applicable income tax treaty, the gain is attributable to a permanent establishment maintained by you in the United States);

•you are a non-resident alien individual who is present in the United States for a period or periods aggregating 183 days or more during the taxable year in which the sale or disposition occurs and certain other conditions are met; or

•the Company’s common stock constitutes a United States real property interest, or USRPI, by reason of its status as a “United States real property holding corporation,” or USRPHC, for U.S. federal income tax purposes at any time within the shorter of (i) the five-year period preceding your sale or other taxable disposition of the Company’s common stock, or (ii) your holding period for its common stock.

The Company believes that it is not currently and will not become a USRPHC for U.S. federal income tax purposes, and the remainder of this discussion so assumes. However, because the determination whether the Company is a USRPHC depends on the fair market value of its USRPIs relative to the fair market value of its other business assets, there can be no assurance that the Company will not become a USRPHC in the future. Even if the Company becomes a USRPHC, however, as long as its common stock is regularly traded on an established securities market, the common stock you own will be treated as a USRPI only if you actually or constructively hold more than five percent of the Company’s outstanding common stock at any time during the shorter of (i) the five-year period preceding your disposition of the Company’s common stock, or (ii) your holding period for the stock.

If you are a non-U.S. holder described in the first bullet above, you will generally be required to pay tax on the net gain derived from the sale under regular graduated U.S. federal income tax rates, and a corporate non-U.S. holder described in the first bullet above also may be subject to the branch profits tax at a 30% rate, or such lower rate as may be specified by an applicable income tax treaty. If you are an individual non-U.S. holder described in the second bullet above, you will be required to pay a flat 30% tax (or such lower rate specified by an applicable income tax treaty) on the gain derived from the sale or other taxable disposition, which gain may be offset by U.S. source capital losses for the year (provided you have timely filed U.S. federal income tax returns with respect to such losses). You should consult any applicable income tax or other treaties that may provide for different rules.

Backup Withholding and Information Reporting

Generally, the Company or an applicable withholding agent must report annually to the IRS, regardless of whether any tax was withheld, the amount of dividends paid to you, your name and address and the amount of tax withheld, if any. A similar report will be sent to you. Pursuant to applicable income tax treaties or other agreements, the IRS may make these reports available to tax authorities in your country of residence.

126

Payments of dividends or of proceeds on the sale or disposition of stock made to you may be subject to information reporting and backup withholding at a current rate of 24% unless you establish an exemption, for example, by properly certifying your non-U.S. status on a timely provided and valid IRS Form W-8BEN, IRS Form W-8BEN-E, or another appropriate version of IRS Form W-8 or applicable documentation. Proceeds of a sale or other disposition of the Company’s common stock conducted through a non-U.S. office of a non-U.S. broker generally will not be subject to backup withholding or information reporting.

Backup withholding is not an additional tax; rather, the U.S. federal income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund or credit may generally be obtained from the IRS, provided that the required information is furnished to the IRS in a timely manner.

Foreign Account Tax Compliance

Sections 1471 through 1474 of the Internal Revenue Code, known as the Foreign Account Tax Compliance Act, or FATCA, impose withholding tax at a rate of 30% on, dividends on and (subject to the proposed Treasury regulations discussed below) gross proceeds from the sale or other disposition of, the Company’s common stock paid to a “foreign financial institution” (as specially defined under these rules), unless such institution enters into an agreement with the U.S. government to withhold on certain payments and to collect and provide to the U.S. tax authorities substantial information regarding the U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners) or otherwise establishes an exemption. FATCA also generally imposes a U.S. federal withholding tax of 30% on dividends on and gross proceeds from the sale or other disposition of the Company’s common stock paid to a “non-financial foreign entity” (as specially defined for purposes of these rules) unless such entity (i) provides the withholding agent with a certification identifying certain substantial direct and indirect U.S. owners of the entity, (ii) certifies that there is none or (iii) otherwise establishes an exemption. The withholding provisions under FATCA generally apply to dividends on our common stock. Although potential withholding under FATCA would also have applied also to of gross proceeds from the sale or other disposition of stock on or after January 1, 2019, recently proposed Treasury regulations eliminate FATCA withholding on payments of gross proceeds entirely. Withholding agents may rely on these proposed Treasury regulations until final Treasury regulations are issued. An intergovernmental agreement between the United States and an applicable foreign country may modify the requirements described in this paragraph. Non-U.S. holders should consult their own tax advisors regarding the possible implications of this legislation on their investment in the Company’s common stock.

127

PLAN OF DISTRIBUTION

Each Selling Stockholder (the “Selling Stockholders”) of the securities and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their securities covered hereby on the principal Trading Market or any other stock exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. A Selling Stockholder may use any one or more of the following methods when selling securities:

•ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

•block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

•purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

•an exchange distribution in accordance with the rules of the applicable exchange;

•privately negotiated transactions;

•settlement of short sales;

•in transactions through broker-dealers that agree with the Selling Stockholders to sell a specified number of such securities at a stipulated price per security;

•through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

•a combination of any such methods of sale; or

•any other method permitted pursuant to applicable law.

The Selling Stockholders may also sell securities under Rule 144 or any other exemption from registration under the Securities Act of 1933, as amended (the “Securities Act”), if available, rather than under this prospectus.

Broker-dealers engaged by the Selling Stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2121; and in the case of a principal transaction a markup or markdown in compliance with FINRA IM-2121.

In connection with the sale of the securities or interests therein, the Selling Stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling Stockholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Stockholders and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each Selling Stockholder has informed the Company that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

128

The Company is required to pay certain fees and expenses incurred by the Company incident to the registration of the securities. The Company has agreed to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act. The Company shall not be responsible for any of the Selling Stockholders’ selling costs incurred pursuant to any available method provided hereunder for selling securities.

We agreed to keep this prospectus effective until the earlier of (i) the date on which the securities may be resold by the Selling Stockholders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for the Company to be in compliance with the current public information under Rule 144 under the Securities Act or any other rule of similar effect or (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the common stock by the Selling Stockholders or any other person. We will make copies of this prospectus available to the Selling Stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders’ of

Context Therapeutics Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Context Therapeutics Inc. (formerly Context Therapeutics LLC) and Subsidiaries (the “Company”) as of December 31, 2019 and 2020, and the related consolidated statements of operations, changes in convertible preferred stock, redeemable common stock and stockholders’ deficit, and cash flows for the years then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of Context Therapeutics Inc. (formerly Context Therapeutics LLC) and Subsidiaries as of December 31, 2019 and 2020, and the results of their operations and their cash flows for each of the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Substantial Doubt About the Company’s Ability to Continue as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has incurred losses and negative cash flows from operations since inception and has a working capital deficit and accumulated deficit that raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 2. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

CONTEXT THERAPEUTICS INC.

Notes to Consolidated Financial Statements

(1) Nature of Business

Context Therapeutics LLC (the “Company”) is a clinical-stage biopharmaceutical company dedicated to improving the lives of women living with hormone-dependent cancer. The Company was organized in April 2015 under the laws of the State of Delaware. The Company’s operations are located in Philadelphia, Pennsylvania. Prior to the effectiveness of the Company’s registration statement, Context Therapeutics LLC intends to convert into a Delaware corporation and change its name to Context Therapeutics Inc. Following the corporate conversion, Context Therapeutics Inc. will hold all property and assets of Context Therapeutics LLC, and all of the debts and obligations of Context Therapeutics LLC will become the debts and obligations of Context Therapeutics Inc.

(2) Risks and Liquidity

The Company has incurred losses and negative cash flows from operations since inception and had an accumulated deficit of $18.8 million as of December 31, 2020. The Company anticipates incurring additional losses until such time, if ever, that it can generate significant revenues from its product candidates currently in development. The Company’s primary source of liquidity to date has been the issuance of convertible promissory notes and convertible preferred stock. In February and March 2021, the Company raised $2.8 million in gross proceeds related to the sale of its Series A convertible preferred stock (“Series A Stock”) and warrants for common stock, however, substantial additional financing will be needed by the Company to fund its operations and to commercially develop its product candidates. There is no assurance that such financing will be available when needed or on acceptable terms. In view of these matters, there is substantial doubt that the Company will be able to continue as a going concern. The Company’s ability to continue as a going concern is dependent upon the Company’s ability to expand operations and to achieve a level of profitability and positive cash flows. The consolidated financial statements of the Company do not include any adjustments relating to the recoverability and classification of recorded assets, or the amounts and classifications of liabilities that might be necessary should the Company be unable to continue as a going concern.

The Company plans to secure additional capital in the future through equity and/or debt financings, partnerships, collaborations, or other sources to carry out the Company’s planned development activities. If additional capital is not available when required, the Company may need to delay or curtail its operations until such funding is received. Various internal and external factors will affect whether and when the Company’s product candidates become approved for marketing and successful commercialization. The regulatory approval and market acceptance of the Company’s product candidates, length of time and cost of developing and commercializing these product candidates and/or failure of them at any stage of the approval process will materially affect the Company’s financial condition and future operations.

The Company faces risks associated with companies whose products are in development. These risks include the need for additional financing to complete its research and development, achieving its research and development objectives, defending its intellectual property rights, recruiting and retaining skilled personnel, and dependence on key members of management, among others.

In March 2020, the World Health Organization declared the outbreak of COVID-19 a global pandemic. The spread of COVID-19 during 2020 has caused worldwide economic downturn and significant volatility in the financial markets. There is significant uncertainty as to the likely effects of this disease which may, among other things, materially impact the Company’s planned clinical trials. This pandemic or outbreak could result in difficulty securing clinical trial site locations, contract research organizations, and/or trial monitors and other critical vendors and consultants supporting the trial. In addition, outbreaks or the perception of an outbreak near a clinical trial site location could impact the Company’s ability to enroll patients. These situations, or others associated with COVID-19, could cause delays in the Company’s clinical trial plans and could increase expected costs, all of which could have a material adverse effect on the Company’s business and its financial condition. At the current time, the Company is unable to quantify the potential effects of this pandemic on its future consolidated financial statements.

(3) Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). Any reference in these notes to applicable guidance is meant to refer to GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) promulgated by the Financial Accounting Standards Board (“FASB”). The consolidated financial statements include the accounts of the Company, Context Biopharma, Inc. and Context Ireland Ltd., the Company’s wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and contingent liabilities at the date of the consolidated financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates.

Estimates and assumptions are periodically reviewed, and the effects of the revisions are reflected in the accompanying consolidated financial statements in the period they are determined to be necessary. Significant estimates and assumptions made in the accompanying consolidated financial statements include, but are not limited to, the fair value of common stock, share-based compensation arrangements, the fair value of convertible debt and in recording the prepayments, accruals and associated expense for research and development activities performed for the Company by third parties.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits. The Company has not experienced any losses in such accounts and management believes that the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held.

Segment Information

Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company views its operations and manages its business in one segment.

Fair Value of Financial Instruments

At December 31, 2020 and 2019, the Company’s financial instruments included cash equivalents, prepaid expenses and other current assets and accounts payable. The carrying amounts of these assets and liabilities approximate fair value due to their short-term nature. Convertible promissory notes are recorded at approximate fair value on a recurring basis (see Note 4 for further discussion).

Cash and Cash Equivalents

The Company considers all highly liquid investments that have original maturities of three months or less when acquired to be cash equivalents. Cash equivalents consist of amounts invested in money market funds.

Deferred Offering Costs

F-8

a result of such offering. Should an in-process equity financing be abandoned, the deferred offering costs will be expensed immediately as a charge to operating expenses in the consolidated statements of operations. As of December 31, 2020 and 2019, the Company had deferred offering costs of $0.1 million and $34,000 related to the Company’s contemplated IPO and the Company’s contemplated Series A Stock financing (See Note 11).

Convertible Preferred Stock and Redeemable Common Stock

The Company accounts for its convertible preferred stock subject to possible conversion in accordance with ASC 480, Distinguishing Liabilities from Equity. Conditionally convertible preferred stock (including shares that feature conversion rights that are either within the control of the holder or subject to conversion upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. The Company’s convertible preferred stock feature redemption rights that are considered by the Company to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, at December 31, 2020 and 2019, the convertible preferred stock subject to contingent redemption are presented as temporary equity, outside of the stockholders’ deficit section of the Company’s consolidated balance sheets. For more information related to the redemption and conversion features of convertible preferred stock, see Note 6. Certain common stock issued to Drexel University (“Drexel”) contain put option rights whereby Drexel may, at their option, request the Company redeem the common stock held by Drexel and at the estimated fair value of the common stock at the time of redemption. Drexel University’s common stock are presented as temporary equity and subsequently remeasured to their estimated redemption value at each reporting period. Drexel’s put option right will terminate immediately prior to and upon consummation of an initial public offering of the Company’s common stock as discussed elsewhere in the registration statement to which these consolidated financial statements are included.

Research and Development Costs

Research and development costs are expensed as incurred. Research and development costs include salaries, share-based compensation, and other operational costs related to the Company’s research and development activities and external costs of outside vendors engaged to conduct clinical studies and other research and development activities.

The Company makes estimates of prepaid/accrued expenses as of each balance sheet date in the financial statements based on facts and circumstances known at that time. If the actual timing of the performance of services or the level of effort varies from the estimate, the Company will adjust the accrual accordingly.

Nonrefundable advance payments for goods and services, including fees for clinical trial expenses, process development or manufacturing and distribution of clinical supplies that will be used in future research and development activities, are deferred and recognized as expense in the period that the related goods are consumed or services are performed.

Share-Based Compensation

The Company measures and recognizes share-based compensation expense for both employee and nonemployee awards based on the grant date fair value of the awards. The Company recognizes share-based compensation expense on a straight-line basis over the requisite service period of the awards, which is generally the vesting period. The Company recognizes forfeitures as they occur.

The Company classifies share-based compensation expense in its consolidated statements of operations in the same manner in which the award recipient’s payroll costs are classified or in which the award recipients’ service payments are classified.

The Company estimates the fair value of employee and non-employee stock awards as of the date of grant using the Black-Scholes option pricing model. The Company historically has been a private company and lacks Company-specific historical and implied volatility information. Therefore, management estimates the expected stock price volatility based on the historical volatility of a publicly traded set of peer companies and expects to continue to do so until such time as it has adequate historical data regarding the volatility of its own publicly traded stock price. The expected term of the Company’s stock awards has been determined utilizing the “simplified” method for awards that

F-9

qualify as “plain-vanilla” stock awards. The risk-free interest rate is determined by reference to the yield curve of a zero-coupon U.S. Treasury bond on the date of grant of the award for time periods approximately equal to the expected term of the award. Expected dividend yield is based on the fact that the Company has never paid cash dividends on common stock and does not expect to pay any cash dividends in the foreseeable future.

In addition, the Company measures and recognizes share-based compensation expense for advisors, officers and director restricted stock awards based on the grant date fair value of the awards.

Income Taxes

The Company is a limited liability company that is treated as a pass-through entity for income tax purposes. For the pass-through entities, income taxes on net earnings are payable by the members or partners and are not reflected in the Company’s financial statements. Context BioPharma Inc. is subject to corporate income taxes, which have been provided for in the financial statements based upon ASC 740, Income Taxes (“ASC 740”). Under ASC 740, deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax reporting. Deferred tax assets are reduced by a valuation allowance if a determination is made that it is more likely than not that some or all of the deferred tax assets will not be realized based on the weight of all available evidence.

Certain operations of the Company are also subject to taxation in the city of Philadelphia and the Company accounts for these taxes based upon the provisions of ASC 740.

As required by ASC 740, the Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an examination. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon settlement with the relevant authority.

The Company will recognize interest and penalties related to uncertain tax positions in income tax expense. As of December 31, 2020 and 2019, the Company had no accrued interest or penalties related to uncertain tax positions and no amounts have been recognized in the Company’s consolidated statements of operations.

(Loss) Income Per Share

The Company computes net income (loss) per share using the weighted-average number of common shares outstanding during the period. For periods with a net loss, basic and diluted net loss per share are the same because the conversion, exercise or issuance of all potential common stock equivalents, which comprise the entire amount of the Company’s outstanding warrants and share-based awards at December 31, 2019, would be anti-dilutive.

For the year ended December 31, 2020, the Company used the two-class method to compute basic net income per common share. Under this method, undistributed earnings are allocated to common stock, the Series Seed Preferred Stock and the Series A Preferred Stock to the extent that the preferred stockholders may share in earnings. In periods of net loss, losses are not allocated to participating securities as the holders of such securities have no obligation to fund losses. The total earnings allocated to common stock is then divided by the weighted average common shares outstanding to determine the basic earnings per share.

For purposes of calculating diluted loss per common share, the denominator includes both the weighted average common shares outstanding and the number of common stock equivalents if the inclusion of such common stock equivalents would be dilutive. Dilutive common stock equivalents potentially include warrants and share-based awards using the treasury stock method. In addition, the Company considers the potential dilutive impact of its preferred stock and convertible debt using the treasury stock and if-converted methods, if either is more dilutive than the two-class method. The two-class method was more dilutive for the year ended December 31, 2020.

However, the actual fair value of warrants issued in conjunction with the Series A preferred stock should have been $0.1 million. The Company believes this is an immaterial misstatement as the change is a reclassification between temporary and permanent equity, is not material to the overall 2020 consolidated financial statements and there is no impact on the Consolidated Statement of Operations or Consolidated Statement of Cash Flows.

Based on an analysis of ASC 250, Accounting Changes and Error Corrections (“ASC 250”), Staff Accounting Bulletin 99 - “Materiality” (“SAB 99”) and Staff Accounting Bulletin 108 - Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements (“SAB 108”), the Company determined that the error in presentation was immaterial to the previously-issued financial statements. The Company analyzed and considered all relevant quantitative and qualitative factors and determined that the prior fiscal year financial statements should be corrected, even though such revision previously was and continues to be immaterial to the prior year financial statements.

Accordingly, the Company restated its presentation to reflect the updated allocation of the fair value of warrants issued in conjunction with the Series A Stock financing within the Company’s Consolidated Balance Sheet as of December 31, 2020 and the Consolidated Statement of Changes in Convertible Preferred Stock, Redeemable Common stock and Stockholders’ deficit for the year then ended.

Emerging Growth Company Status

The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act, until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.

balance sheet for those leases classified as operating leases under previous GAAP. In transition, entities may also elect a package of practical expedients that must be applied in its entirety to all leases commencing before the adoption date, unless the lease is modified, and permits entities to not reassess (a) the existence of a lease, (b) the lease classification or (c) the determination of initial direct costs, as of the adoption date, which effectively allows entities to carryforward accounting conclusions under previous GAAP. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements, which provides entities an optional transition method to apply the guidance under Topic 842 as of the adoption date, rather than as of the earliest period presented. In June 2020, the FASB issued ASU 2020-05 that further delayed the effective date of Topic 842 to fiscal years beginning July 1, 2022, and interim periods within those years. The Company is currently evaluating the impact of adopting this guidance to its consolidated financial statements but does not believe this adoption will have a material impact due to the fact that the Company does not have any long-term lease commitments.

In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Non-employee Share-Based Payment Account, which expands the scope of Topic 718, Compensation-Stock Compensation to include share-based payments issued to non-employees for goods or services. Consequently, the accounting for share-based payments to non-employees and employees will be substantially aligned. The Company early adopted this standard as of January 1, 2019 and the impact was immaterial to the Company’s consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820). This guidance modifies disclosure requirements related to fair value measurement and is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Implementation on a prospective or retrospective basis varies by specific disclosure requirement. Early adoption is permitted. ASU 2018-13 also allows for early adoption of any removed or modified disclosures upon issuance of ASU 2018-13 while delaying adoption disclosures until their effective date. The Company adopted this guidance on January 1, 2019 and it had no impact on the Company’s consolidated financial statements.

(4) Fair Value Measurements

The Company utilizes a valuation hierarchy that prioritizes fair value measurements based on the types of inputs used for the various valuation techniques related to its financial assets and financial liabilities. The three levels of inputs used to measure fair value are described as follows:

Level 1 – Observable inputs such as quoted prices in active markets.

Level 2 – Inputs, other than the quoted prices in active markets that are observable either directly or indirectly.

Level 3 – Unobservable inputs in which there is little or no market date, which require the reporting entity to develop its own assumptions.

In accordance with the fair value hierarchy described above, the following table sets forth the Company’s assets and liabilities measured at fair value on a recurring basis:


			December 31, 2020
	Total		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

As further described in Note 5, the Company issued convertible promissory notes from inception through April 2019 (the “Junior Convertible Notes”) to various investors and from October 2019 through March 2020, the Company issued convertible bridge notes to the Co-Founder and Chief Executive Officer (the “Convertible Bridge Notes”). During April 2020, certain of the Junior Convertible Notes were converted into Senior Convertible Notes (the “Senior Convertible Notes”) (collectively, the “Convertible Promissory Notes”).

Due to the number of embedded provisions contained in the Convertible Promissory Notes and Convertible Bridge Notes, the fair value option, as prescribed by ASC 815, was elected and applied to all Convertible Promissory Note and Convertible Bridge Note issuances since the Company’s inception in 2015, in connection with the preparation of these financial statements. The fair value of the Convertible Promissory Notes and Convertible Bridge Notes is determined using a scenario-based analysis that estimates the fair value based on the probability-weighted present value of expected future investment returns, considering each of the possible outcomes available to the noteholders, including various IPO, settlement, equity financing, corporate transaction and dissolution scenarios.

The Company adjusts the carrying value of its Convertible Promissory Notes and Convertible Bridge Notes to their estimated fair value at each reporting date, with any related increases or decreases in the fair value recorded as change in fair value of convertible promissory notes in the consolidated statement of operations. The change in fair value of convertible promissory notes within the 2020 consolidated statement of operations also includes reversals of gains and losses previously recognized by the Company upon conversion of the notes (Note 5).

The fair value of the Senior Convertible Notes at December 31, 2020 was calculated using an option pricing model (“OPM”) framework and utilized the back-solve method for inferring and allocating the equity value predicated on the concurrent sale of Series A Stock. This method was selected as it was concluded that the sale of the Series A Stock was an arm’s-length transaction. Application of the OPM back-solve method involves making assumptions for the expected time to liquidity and volatility, and then solving for the value of equity such that value for the most recent financing equals the amount paid.

The fair value of the Junior Convertible Notes and Convertible Bridge Notes at December 31, 2019 was estimated using a Contingent Claims Analysis (“CCA”), also called the Option Pricing Method, by an independent third-party valuation specialist. The model estimated the fair value of the Convertible Promissory Notes based on accrued interest, the time to a future liquidity event and the value of a future liquidity event. Because the Company’s capital structure varied, it was necessary to value the securities in a lattice framework rather than using the Black-Scholes-Merton formula.

(5) Convertible Promissory Notes

Junior Convertible Notes

From inception through December 2018, the Company issued Junior Convertible Notes that had an aggregate issuance date fair value of $15.8 million, an aggregate principal balance of $10.7 million and bore interest at rates ranging from 3.00% to 7.73% per year. From January 2019 through April 2019, the Company issued Junior Convertible Notes in the aggregate principal of $1.5 million that bore interest at rates ranging between 6.00% and 15.00% per year. From April 2015 through December 2017, the Company issued demand notes to the Chief Executive Officer and an immediate family member (the “Related Party”) with an aggregate principal balance of $1.8 million that bore interest at rates ranging from 3.00% to 6.00% per year. During April 2019, $1.9 million of principal and interest was converted from demand notes to a Junior Convertible Note bearing interest at a rate of 15.00%. Additionally, in July 2019, the Company issued $1.2 million of Junior Convertible Notes in lieu of severance payments to former executives, of which $0.9 million and $0.3 million were expensed to general and administrative and research and development expense, respectively, during the year ended December 31, 2019. At December 31, 2019, principal of $5.7 million of Junior Convertible Notes outstanding were held by the Related Party. In the event of qualified financing resulting in gross proceeds of various amounts (“Junior Note Qualified Financing”) the outstanding principal and interest of the Junior Convertible Notes would automatically convert into Series Seed preferred stock at a price equal to 75% to 80% of the issue price per share of the stock issued in the Junior Note Qualified Financing and on the same terms and conditions of such Junior Note Qualified Financing.

All of the outstanding principal and accrued but unpaid interest associated with the Junior Convertible Notes converted into 2,615,553 shares of Series Seed Stock in May 2020, of which 840,363 shares were issued to the Related Party. Due to certain embedded features within the Junior Convertible Notes, the Company elected to account for these notes and all their embedded features under the fair value option. At the time of conversion, the estimated fair value of the Junior Convertible Notes was $6.3 million and was reclassified to Series Seed convertible preferred equity. In connection with the conversion in 2020, the Company recorded a non-cash credit of $7.7 million related to the final decrease in fair value of the Junior Convertible Notes. For the year ended December 31, 2019, the Company recognized $0.2 million in the consolidated statement of operations related to decreases in the fair value of the Junior Convertible Notes. For the year ended December 31, 2019, the Company recognized $1.1 million of interest expense in connection with the Junior Convertible Notes, including $0.5 million payable to the Related Party.

Convertible Bridge Notes

F-14

December 31, 2021 (“Maturity Date”). In the event of qualified financing resulting in gross proceeds of $1.0 million (“Bridge Note Qualified Financing”), the outstanding principal and interest of the Convertible Bridge Notes would automatically convert into Series A Stock at a price equal to the issue price per share of the stock issued in the Bridge Note Qualified Financing and on the same terms and conditions of such Bridge Note Qualified Financing. In the event that a Bridge Note Qualified Financing was not consummated prior to the Maturity Date, then, at the election of the holder made at least five days prior to the Maturity Date, effective upon the Maturity Date, the outstanding principal balance and any unpaid accrued interest under the Senior Convertible Notes was to convert into Series A Stock of the Company at a conversion price equal to 80% of the conversion price. On December 22, 2020, the outstanding principal and accrued but unpaid interest associated with the Convertible Bridge Notes converted into 78,178 Series A Stock.

Due to certain embedded features within the Convertible Bridge Notes, the Company elected to account for these notes and all their embedded features under the fair value option. At the time of conversion, the estimated fair value of the Convertible Bridge Notes was $0.5 million and was reclassified to Series A convertible preferred equity. In connection with the conversion in December 2020, the Company recorded a non-cash credit of $0.1 million related to the final decrease in fair value of the Convertible Bridge Notes. For the year ended December 31, 2019, the Company recognized a change $0.1 million in the consolidated statement of operations related to increases in the fair value of the Convertible Bridge Notes. For the years ended December 31, 2020 and 2019, the Company recognized approximately $30,000 and approximately $5,000, respectively, of interest expense in connection with the Convertible Bridge Notes.

Senior Convertible Notes

In April 2020, $5.1 million of principal and $0.6 million of accrued interest related to certain Junior Convertible Notes were converted into Senior Convertible Notes. Of the Senior Convertible Notes issued in 2020, $2.5 million of principal and $0.4 million of accrued interest were issued to the Related Party. The Senior Convertible Notes bear interest at a rate of 6.0% per year and mature on December 31, 2021 (“Maturity Date”). All of the Company’s assets, including intellectual property, are pledged as collateral to the Senior Convertible Note holders. In the event of a qualified financing, whereby the Company issues and sells its Series A Stock and raises capital of at least $2.5 million of total gross proceeds in cash (“Senior Note Qualified Financing”), the outstanding principal and interest of the Senior Convertible Notes would automatically convert into Series A Stock at a price equal to the issue price per share of the stock issued in the Senior Note Qualified Financing and on the same terms and conditions of such Senior Note Qualified Financing. In the event that a Senior Note Qualified Financing is not consummated prior to the Maturity Date, then, at the election of the holder made at least five days prior to the Maturity Date, effective upon the Maturity Date, the outstanding principal balance and any unpaid accrued interest under the Senior Convertible Notes shall be converted into Series A of the Company at a conversion price equal to 90% of the conversion price. In the event that the Company consummates a sale of the Company prior to the conversion or repayment in full of the Senior Convertible Notes, (i) the Company will give the holder at least five days prior written notice of the anticipated closing date of such sale of the Company and (ii) at the closing of such sale of the Company, in lieu of the principal and interest that would otherwise be payable on the Maturity Date, the Company will pay the holder an aggregate amount equal to the greater of: (i) one (1) times the aggregate amount of principal and interest then outstanding under the Senior Convertible Notes in full satisfaction of the Company’s obligations under the Senior Convertible Notes; or (ii) the sale proceeds multiplied by the pro rata ownership of the holder based upon a conversion of the Senior Convertible Notes at a price equal to the conversion price then in effect.

For the year ended December 31, 2020, the Company recognized a credit of $2.1 million in the consolidated statement of operations related to decreases in the fair value of the Senior Convertible Notes. For the year ended December 31, 2020, the Company recognized $0.3 million of interest expense in connection with the Senior Convertible Notes, including $0.1 million payable to the Related Party.

Paycheck Protection Program

F-15

implemented by the U.S. Small Business Administration. In June 2020, the Paycheck Protection Program Flexibility Act was enacted, which among other things, extended the deferral period for loan payments to either (1) the date that Small Business Administration remits the borrower’s loan forgiveness amount to the lender or (2) if the borrower does not apply for loan forgiveness, 10 months after the end of the borrower’s loan forgiveness covered period. The Loan matures in 2 years and bears interest at a rate of 1.0% per year, with all payments deferred through September 5, 2021. Principal and interest are payable monthly commencing on September 5, 2021 and may be prepaid by the Company at any time prior to maturity without penalty. The Company may apply for forgiveness of amounts due under the Loan, with the amount of potential loan forgiveness to be calculated in accordance with the requirements of the PPP based on payroll costs, any mortgage interest payments, any covered rent payments and any covered utilities payments during the 8-24 week period after the origination date of the Loan. The Company utilized the proceeds of the Loan for payroll and other qualifying expenses, but there can be no assurances that any portion of the Loan will be forgiven.

At December 31, 2020, the outstanding principal balance of the Loan was $124,000, of which approximately $55,000 is payable in 2021 and approximately $69,000 is payable in 2022 unless otherwise forgiven.

(6) Convertible Preferred Stock, Redeemable Common Stock and Common Stock

Series A convertible preferred stock and Series Seed convertible preferred stock

In May 2020, the Company converted $11.7 million of principal and interest related to certain Junior Convertible Notes into 2,615,553 shares of Series Seed Stock at prices ranging from $4.28 to $4.56 per share. In May 2020, the Related Party purchased 8,771 shares of Series Seed Stock at a price of $5.70 per share for $50,000.

Throughout 2020, the Company sold 132,537 shares of Series A Stock to the Related Party for $7.168 per share for proceeds of $1.0 million. The Company also issued 33,129 warrants to purchase common stock at an exercise price of $7.168 per share to the Series A Stock holder as part of the Series A Stock financing.

In December 2020, $0.6 million in principal and accrued interest related to the Convertible Bridge Notes were converted into 78,178 shares of Series A Stock. The Company also issued 19,544 warrants to purchase common stock at an exercise price of $7.168 per share to the Series A stockholders as part of the conversion from Convertible Bridge Notes to Series A Stock.

The following is a summary of the rights, preferences, and terms of the Series A Stock and Series Seed Stock (collectively, Convertible Preferred Stock):

Distribution

Series A stockholders shall receive a non-cumulative distribution of 6% per year of the original capital contribution, which shall be payable upon the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company (“Dissolution Event”), or the redemption or repurchase of any Series A Stock. Series Seed Stock does not receive a distribution right.

Liquidation

Upon a Dissolution Event, the holders of shares of Series A Stock shall receive the greater of 1.5 times the original issuance price plus any accrued distributions or the amount that such Series A stockholders would receive if the Series A Stock were converted to common stock, prior to any distribution with respect to Series Seed Stock or common stock.

After amounts paid out to the Series A stockholders upon a Dissolution Event, the Series Seed Stock then outstanding shall be entitled to be paid out in accordance with the positive balance in their capital accounts with respect to their Series Seed Stock, after giving effect to all contributions, distributions and allocations with respect to such Series Seed Stock for all periods, before any payment shall be made to the holders of common stock.

F-16

Conversion Rights

Each share of Convertible Preferred Stock is convertible, at the option of the holder thereof, at any time, and without the payment of additional consideration, into a number of fully paid and nonassessable common stock as determined by dividing the original issue price for the Convertible Preferred Stock by the conversion price for the Convertible Preferred Stock in effect at the time of conversion, except as otherwise defined in the Operating Agreement (the “Operating Agreement”). Notwithstanding the foregoing, in the event of a liquidation, dissolution, or winding up of the Company or acquisition of the majority of the Company’s assets, the Series Seed Stock conversion right will terminate at the close of business on the last full day preceding the date fixed for the first payment of any funds and assets distributable on such event to the stockholders’ holding Series Seed Stock. No fractional common stock will be issued upon conversion of the Convertible Preferred Stock. In lieu of any fractional shares, the Company shall pay cash equal to such fraction multiplied by the fair market value of a common stock as determined in good faith by the Management Committee of the Company.

Voting Rights

In connection with the Company’s issuance of Series A Stock, the Company’s Management Committee shall be reconstituted so as to be comprised on five members, including one member appointed by a majority of the Series A stockholders, one member appointed by a majority of the Series Seed stockholders, two independent members and the Company’s Chief Executive Officer.

Redemption

Due to certain deemed liquidation events that are outside of the control of the Company, the Series A Stock and Series Seed Stock are contingently redeemable and presented as temporary equity in the accompanying consolidated balance sheets.

Redeemable Common Stock and Common Stock

Pursuant to the Operating Agreement filed in May 2015, as amended, the Company is authorized to issue a total of 30,000,000 Series A Stock, Series Seed Stock, and common stock. Series Seed Stock and common stockholders do not have the power to take part in the direct management of the Company and have limited voting rights.

In connection with entering into a patent license agreement with Drexel University (Note 8), the Company issued 16,666 common stock during 2015 that include a put option right whereby Drexel may, at their option, request the Company repurchase the common stock held by Drexel upon the earlier of (i) several triggering events associated with insolvency and bankruptcy matters of the Company and (ii) the tenth anniversary of the original issuance of common stock to Drexel. Redemption, if elected by Drexel, is equal to the estimated fair value of common stock at the time of redemption. The shares held by Drexel are classified as temporary equity and presented outside of stockholders’ deficit within the accompanying consolidated balance sheets. Changes in redemption value are recognized at each reporting period and based upon the estimated fair value of the redeemable common stock held by Drexel.

During the years ended December 31, 2020 and 2019, the Company issued 7,512 and 23,841 shares of common stock, respectively, to members of the board of managers as compensation for their services. The Company recorded share-based compensation expense of $0.1 million in general and administrative expense during the year ended December 31, 2020. The Company recorded share-based compensation expense of $0.1 million and $0.3 million in research and development and general and administrative expense, respectively, during the year ended December 31, 2019.

Warrants for Common Stock

Since inception, the Company has granted warrants to purchase common stock at various dates. At December 31, 2020, the Company had the following warrants outstanding to acquire common stock:


	Outstanding	Exercise price		Expiration dates
Issued in 2016 and 2017	6,431	$	4.28	June 2036 to December 2037
Issued in 2018 and 2019	87,716	$	4.56	March 2038 to October 2039

Issued as part of Series A to Related Party	52,680	$	7.17	December 2025
	160,108

Reverse Stock Split

In June 2021, the Company effected a one-for-6 reverse stock split of its common stock and convertible preferred stock. No fractional shares were issued in connection with the reverse stock split. Any fractional share resulting from the reverse stock split was rounded down to the nearest whole share, and in lieu of any fractional shares, the Company will pay in cash to the holders of such fractional shares an amount equal to the fair value, as determined by the board of directors, of such fractional shares. All common stock, convertible preferred stock, per share and related information presented in the consolidated financial statements and accompanying notes have been retroactively adjusted to reflect the reverse stock split.

(7) Share-based Compensation

The Company’s 2015 Equity Incentive Plan (the “2015 Plan”) authorizes the board of managers or a committee of the board of managers to grant options to acquire common stock (“share-based awards”), to eligible employees, outside directors and consultants of the Company. The 2015 Plan reserves 166,666 shares for issuance. As of December 31, 2020, 141,836 shares remained available for future grants.

Share-based awards generally vest over a period of one to three years, and share-based awards that lapse or are forfeited are available to be granted again. The contractual life of all share-based awards is 10 years. The expiration dates of the outstanding share-based awards range from January 2028 to May 2030.

The Company measures share-based awards at their grant-date fair value and records compensation expense on a straight-line basis over the service period of the awards. Share-based compensation is allocated to employees and consultants based on their respective departments. All board of directors’ compensation is charged to general and administrative expense.

The Company recorded share-based compensation expense of $75,000 and $29,000 in research and development and general and administrative expense, respectively, during the year ended December 31, 2020. The Company recorded share-based compensation expense of $29,000 and $16,000 in research and development and general and administrative expense, respectively, during the year ended December 31, 2019.

The assumptions used in the Black-Scholes option pricing model to determine the fair value of share-based awards granted to employees during 2020 were as follows:


			2020
Volatility			97.86%
Risk free rate			0.51%
Expected term			5.44
Dividend			—
Fair value of common stock			13.55

F-18

The following table summarizes the share-based award activity for the periods presented:


	Number of Shares	Weighted Average Exercise Price Per Share		Weighted Average Remaining Contractual Term (years)
Outstanding at December 31, 2019	10,414	$	20.67	8.2
Granted	14,416	$	15.79
Outstanding at December 31, 2020	24,830	$	17.84	8.4
Exercisable at December 31, 2020	15,724	$	18.37	8.0
Vested and expected to vest at December 31, 2020	24,830	$	17.84	8.4

The weighted average fair value of share-based awards granted during the year ended December 31, 2020 was $9.34. No options were granted in 2019. As of December 31, 2020, the unrecognized compensation cost related to outstanding share-based awards was $0.1 million and is expected to be recognized as expense over a weighted-average period of approximately 1.17 years.

Restricted Stock Units

The Company issues restricted stock units (“RSU”) to employees and consultants that generally vest monthly over one to three-year periods. The fair value of an RSU is equal to the fair market value price of the Company’s common stock on the date of grant. RSU expense is amortized straight-line over the service period.

The following table summarizes activity related to RSU share-based payment awards:


	Number of RSUs	Weighted Average Grant Date Fair value
Unvested balance at January 1, 2019	20,366	$ 16.44
Vested	20,336	$ 16.44
Unvested balance at December 31, 2019	—
Granted	177	$ 13.55
Vested	132	$ 13.55
Unvested balance at December 31, 2020	45	$ 13.55

The Company recorded share-based compensation expense of $1,800 and $0.3 million in general and administrative expense for the years ended December 31, 2020 and 2019, respectively, related to RSUs. As of December 31, 2020, the total unrecognized expense related to all RSUs was $400, which the Company expects to recognize over a weighted-average period of 0.25 years.

(8) Commitments and Contingencies

Patent License Agreement with Drexel University

In November 2015, the Company entered into a patent license agreement, as amended, (the “Drexel License Agreement”) with Drexel for license rights to patents for certain intellectual property and know-how related to certain technology.

As part of the Drexel License Agreement, the Company issued Drexel 16,666 shares of common stock. In partial consideration of the Drexel License Agreement, the Company is required to pay to Drexel certain milestone payments, ranging from $10,000 to $0.2 million on the achievement of certain milestone events for each licensed product.

F-19

The Company has agreed to pay Drexel a royalty in the low single digits of net sales for each licensed product on a country-by-country, licensed product-by-licensed product basis on issued or pending valid claims. The Company may credit against amounts payable to Drexel, on a country-by-country, licensed product-by-licensed product basis up to 50% of any third-party payments which the Company must make on account of third-party license agreements.

In partial consideration of the Drexel License Agreement, the Company will pay to Drexel a de-escalating sublicense fee on a quarterly basis of a high single-digit percentage that decreases to a mid-single digit percentage as time passes. In addition, the Company will make payments of the fair market value of all other consideration received by the Company from sublicensees during the quarter, other than: (a) royalties paid to the Company by a sublicensee based upon sales or net sales by the sublicensee; (b) equity investments in the Company by a sublicensee up to the amount of fair market value of the equity purchased on the date of the investment; (c) loan proceeds paid to the Company by a sublicensee in an arm’s length, full recourse debt financing to the extent that such loan is not forgiven; and (d) sponsored research funding, paid to the Company by a sublicensee in a bona fide transaction for future research to be performed by the Company.

Collaboration Agreement with Tyligand Bioscience

In March 2020, the Company entered into a license (the “Tyligand License Agreement”) and process development agreement (the “Tyligand Process Development Agreement”) (collectively, the “Tyligand Agreements”) with Tyligand Bioscience (Shanghai) Limited (“Tyligand”) for the development, manufacturing, registration and future commercialization of onapristone extended release (“ONA-XR”).

Under the terms of the Tyligand Agreements, Tyligand will be solely responsible for the design and optimization of an improved manufacturing process for ONA-XR. Upon completion of specific performance-based milestones, Tyligand will be granted the exclusive right to ONA-XR and will be solely responsible for the development and commercialization of ONA-XR in China, Hong Kong and Macau (the “Territory”). The Company will retain rest of world rights to commercialize ONA-XR.

Under the Tyligand Process Development Agreement, the Company is obligated to pay Tyligand $0.8 million and a certain number of warrants exercisable for common stock upon successful completion of the manufacturing development plan, $2.0 million upon the completion of scale-up of the first cumulative 100 kilograms of the GMP-grade compound and $3.0 million upon the Company’s completion of scale-up of the first cumulative 300 kilograms of the GMP-grade compound. In consideration of and upon Tyligand’s successful completion of the development plan, within 30 days at the end of each calendar quarter, the Company shall pay Tyligand 1% of net sales of finished product utilizing the compound substantially manufactured in accordance with the process and specifications outlined in the Tyligand Process Development Agreement.

Per the Tyligand License Agreement, Tyligand shall pay the Company a non-refundable, non-creditable royalty at a rate in the mid-single digits of the net sales of each product in the Territory in each calendar quarter commencing with the first commercial sale of such product in the field in the Territory and ending upon the latest of (i) the sale of a generic product in the territory and (ii) 15 years after the date of the first commercial sale of product in the territory.

Operating Leases

The Company leases its corporate offices in Philadelphia, Pennsylvania under a month-to-month lease arrangement. The Company recorded rent expense of approximately $10,000 and $44,000 for the years ended December 31, 2020 and 2019, respectively.

Litigation

Liabilities for loss contingencies arising from claims, assessments, litigations, fines, penalties, and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. The Company believes no matters exist at either December 31, 2020 or 2019 that will have a material impact to the Company’s financial position, results of operations or cash flows.

F-20

(9) Income Taxes

The tax effects of temporary differences that gave rise to significant portions of the deferred tax assets and liabilities were as follows:


	December 31,
	2020		2019
Deferred tax assets:
Net operating loss carryforwards	$	3,199,412	$	3,072,704
Research and development credits	326,551		245,534
Share-based compensation	43,526		36,967
Gross deferred tax assets	3,569,489		3,355,205
Less: valuation allowance	(3,569,489)		(3,355,205)
	$	—	$	—

In assessing the need for a valuation allowance, management must determine that there will be sufficient taxable income to allow for the realization of deferred tax assets. Based upon the historical and anticipated future losses, management has determined that the deferred tax assets do not meet the more likely than not threshold for realizability. Accordingly, a full valuation allowance has been recorded against the Company’s net deferred tax assets as of December 31, 2020 and 2019. The valuation allowance increased by $214,979 and $869,175 during the years ended December 31, 2020 and 2019, respectively.

A reconciliation of the federal income tax rate to the Company’s effective tax rate is as follows:


	Year ended December 31,
	2020		2019
Federal tax expense/(benefit) at statutory rate	21.0	%	(21.0)	%
State tax, net of federal benefit	11.8		(6.4)
Non-taxable partnership income	(25.5)		15.4
Permanent differences	(9.2)		(0.1)
Research and development	(1.2)		(1.6)
Change in valuation allowance	3.1		13.7
	—	%	—	%

The following table summarizes carryforwards of federal, state and local net operating losses (“NOL”) and research tax credits:


	December 31,
(in thousands)	2020		2019
NOL carryforwards—Federal	$	8,030,123	$	6,599,499
NOL carryforwards—State	8,030,123		6,599,499
NOL carryforwards—Local	15,399,777		20,398,658
Research tax credits—Federal	326,551		245,534

The NOL carryforwards begin expiring in 2037 for federal and state income tax purposes, however; all federal NOL carryforwards generated subsequent to January 1, 2018, are able to be carried forward indefinitely. Local NOL carryforwards expire after three years with the 2018 NOL set to expire in 2021. As of December 31, 2020 and 2019 the Company had federal research and development tax credit carryforwards of $326,551 and $245,534, respectively that will begin to expire in 2037, unless previously utilized.

F-21

The NOL and tax credit carryforwards are subject to review and possible adjustment by the Internal Revenue Service and state tax authorities. NOL and tax credit carryforwards may become subject to an annual limitation in the event of certain cumulative changes in the ownership interest of significant stockholders over a three-year period in excess of 50%, as defined under Sections 382 and 383 of the Internal Revenue Code, respectively, as well as similar state provisions. This could limit the amount of tax attributes that can be utilized annually to offset future taxable income or tax liabilities. The amount of the annual limitation is determined based on the value of the Company immediately prior to the ownership change. Subsequent ownership changes may further affect the limitation in future years. To date, the Company has not performed an analysis to determine whether or not ownership changes have occurred since inception. State and local NOLs may also be limited.

As of December 31, 2020 and 2019, the Company had no accrued interest or penalties related to uncertain tax positions and no amounts have been recognized in the Company’s consolidated statement of operations. Due to NOLs and tax credit carry forwards that remain unutilized, income tax returns for tax years from all years remain subject to examination by the taxing jurisdictions. The NOL carryforwards remain subject to review until utilized.

(10) Related Party Transactions

Since inception through December 31, 2020, the Company entered into various convertible note agreements with the Related Party. The terms of the convertible notes and their subsequent conversions are further described in more detail in Note 5 and Note 6.

(11) Subsequent Events

In preparing the consolidated financial statements as of and for the year ended December 31, 2020, the Company evaluated subsequent events for recognition and measurement purposes through March 19, 2021, the date that the Report of independent registered public accounting firm was originally issued, and the audited annual consolidated financial statements were available for issuance. The Company has concluded that no events or transactions have occurred that require disclosure in the accompanying consolidated financial statements other than those listed below.

During February 2021 and March 2021, the Company raised $2.8 million of gross proceeds from the sale of 389,947 shares of Series A Stock and 97,478 warrants to purchase common stock at an exercise price of $7.168 per share to the Series A stockholders as part of the Series A Stock financing. In addition, Senior Convertible Notes with a principal balance of $5.7 million and accrued interest of $0.3 million converted into 844,824 shares of Series A Stock in February 2021.

In April 2021, the Company completed a reverse triangular merger, resulting in Context Therapeutics Inc becoming the sole holder of 100% of the membership interests in Context Therapeutics LLC, which resulted in all of the common stock, preferred stock and all options, warrants or other rights to purchase common or preferred stock of Context Therapeutics LLC converting into common stock, preferred stock and all options, warrants or other rights to purchase common or preferred stock of Context Therapeutics Inc. As a result of the reverse triangular merger, the total number of shares of stock that the Company has authority to issue is 120,000,000 shares, of which 100,000,000 shares are common stock, $0.001 par value per share, 10,000,000 shares are Undesignated Preferred Stock, $0.001 par value per share, 5,000,000 shares of Series Seed Convertible Preferred Stock, $0.001 par value per share and 5,000,000 shares of Series A Convertible Preferred Stock, $0.001 par value per share. Based on this being a transaction between entities under common control the carryover basis of accounting was used to record the assets, liabilities and equity of Context Therapeutics LLC. Further, as a common control transaction the consolidated financial statements of the Company reflect the merger transaction as if it had occurred as of the earliest period presented herein.

CONTEXT THERAPEUTICS INC.

Notes to Unaudited Condensed Consolidated Financial Statements

(1) Organization and Description of Business

Context Therapeutics Inc. (the “Company”) is a clinical-stage biopharmaceutical company dedicated to improving the lives of women living with cancer. The Company was organized in April 2015 under the laws of the State of Delaware. The Company’s operations are located in Philadelphia, Pennsylvania. In April 2021, the Company completed a reverse triangular merger, which resulted in Context Therapeutics Inc. becoming the sole holder of 100% of the membership interests in Context Therapeutics LLC, which resulted in all common units, preferred units, options, warrants or other rights to purchase common or preferred units of Context Therapeutics LLC converting into common stock, preferred stock, options, warrants or other rights to purchase common or preferred stock of Context Therapeutics Inc. As this was a transaction between entities under common control, the carryover basis of accounting was used to record the assets, liabilities and equity of Context Therapeutics LLC. Further, as a common control transaction the condensed consolidated financial statements of the Company reflect the merger transaction as if it had occurred as of the earliest period presented herein.

(2) Risks and Liquidity

The Company has incurred losses and negative cash flows from operations since inception and had an accumulated deficit of $26.2 million as of September 30, 2021. The Company anticipates incurring additional losses until such time, if ever, that it can generate significant revenues from its product candidates currently in development. Management believes its cash and cash equivalents of $0.4 million as of September 30, 2021, together with the gross proceeds of $28.8 million from its initial public offering ("IPO") in October 2021 (note 10) and expected gross proceeds of $31.3 million from its private placement in December 2021 (note 10), are sufficient to fund the projected operations for at least the next 12 months from the issuance date of these condensed consolidated financial statements. Substantial additional financing will be needed by the Company to fund its operations and to commercially develop its product candidates.

The Company plans to seek additional capital in the future through equity and/or debt financings, partnerships, collaborations, or other sources to carry out the Company’s planned development activities. If additional capital is not available when required, the Company may need to delay or curtail its operations until such funding is received. Various internal and external factors will affect whether and when the Company’s product candidates become approved for marketing and successful commercialization. The regulatory approval and market acceptance of the Company’s product candidates, length of time and cost of developing and commercializing these product candidates and/or failure of them at any stage of the approval process will materially affect the Company’s financial condition and future operations.

In October 2021, the Company closed an IPO, in which it issued and sold 5,750,000 shares at a public offering price of $5.00 per share. In addition, at the closing of the IPO, the Company issued warrants to purchase up to 250,000 shares of common stock to designees of the placement agent. The placement agent's warrants have an exercise price of $6.25 per share and a term of five years from the date of issuance. Immediately prior to the completion of the IPO, all of the Company’s preferred stock converted into an aggregate of 4,836,867 shares of common stock and 480,415 warrants converted into 9,816 shares of common stock. The Company received gross proceeds of approximately $28.8 million as a result of the offering.

On December 1, 2021, the Company entered into a definitive securities purchase agreement for a private placement of 5,000,000 shares of common stock together with warrants to purchase 5,000,000 shares of common stock that will result in gross proceeds of approximately $31.3 million, before deducting placement offering expenses. Each share of common stock and accompanying warrant are being sold together at a combined offering price of $6.25. The warrants have a term of 5.5 years and an exercise price of $6.25 per share. The private placement is expected to close on December 6, 2021, subject to customary closing conditions.

objectives, defending its intellectual property rights, recruiting and retaining skilled personnel, and dependence on key members of management, among others.

In March 2020, the World Health Organization declared the outbreak of COVID-19 a global pandemic. The spread of COVID-19 during 2020 and 2021 has caused worldwide economic downturn and significant volatility in the financial markets. There is significant uncertainty as to the likely effects of this disease which may, among other things, materially impact the Company’s planned clinical trials. This pandemic or outbreak could result in difficulty securing clinical trial site locations, contract research organizations, and/or trial monitors and other critical vendors and consultants supporting the trials. In addition, outbreaks or the perception of an outbreak, near a clinical trial site location could impact the Company’s ability to enroll patients. These situations, or others associated with COVID-19, could cause delays in the Company’s clinical trial plans and could increase expected costs, all of which could have a material adverse effect on the Company’s business and its financial condition. At the current time, the Company is unable to quantify the potential effects of this pandemic on its future consolidated financial statements.

(3) Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and note disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information not misleading. Any reference in these notes to applicable guidance is meant to refer to GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (“FASB”).

In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all normal and recurring adjustments (which consist primarily of accruals and estimates that impact the financial statements) considered necessary to present fairly the Company’s financial position as of September 30, 2021, and its results of operations for the three and nine months ended September 30, 2021 and 2020 and cash flows for the nine months ended September 30, 2021 and 2020. Operating results for the three and nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. The unaudited condensed consolidated financial statements, presented herein, do not contain the required disclosures under GAAP for annual financial statements. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the annual audited consolidated financial statements and related notes as of and for the year ended December 31, 2020. The consolidated financial information as of December 31, 2020 included herein has been derived from the annual audited consolidated financial statements.

The unaudited condensed consolidated financial statements include the accounts of the Company, Context Therapeutics LLC, Context Biopharma, Inc. and Context Ireland Ltd., the Company’s wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and contingent liabilities at the date of the consolidated financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates.

Estimates and assumptions are periodically reviewed, and the effects of the revisions are reflected in the accompanying unaudited interim condensed consolidated financial statements in the period they are determined to be necessary. Significant estimates and assumptions made in the accompanying unaudited interim condensed consolidated financial statements include, but are not limited to, the fair value of common stock, share-based compensation arrangements, the fair value of convertible debt and in recording the prepayments, accruals and associated expense for research and development activities performed for the Company by third parties.

Concentrations of Credit Risk

Segment Information

Fair Value of Financial Instruments

At September 30, 2021 and December 31, 2020, the Company’s level 1 financial instruments included cash equivalents and accounts payable. The carrying amounts of these assets and liabilities approximate fair value due to their short-term nature. Convertible promissory notes are recorded at approximate fair value on a recurring basis (see Note 4 for further discussion).

Cash and Cash Equivalents

Deferred Offering Costs

The Company capitalizes certain legal, professional, accounting and other third-party fees that are directly associated with in-process equity financings as deferred offering costs until such financings are consummated. After consummation of an equity financing, the costs are recorded as a reduction of additional paid-in capital generated as a result of such offering. Should an in-process equity financing be abandoned, the deferred offering costs will be expensed immediately as a charge to operating expenses in the consolidated statements of operations. As of September 30, 2021 and December 31, 2020, the Company had deferred offering costs of $1.8 million and $0.1 million, respectively, related to the Company’s in-process IPO and the Company’s Series A convertible preferred stock (“Series A Stock”) financing (see Note 6). All deferred offering costs related to the Company’s Series A Stock financing were recorded against Series A Stock upon completion of the financing in April 2021.

Convertible Preferred Stock and Redeemable Common Stock

The Company accounts for its convertible preferred stock subject to possible conversion in accordance with ASC 480, Distinguishing Liabilities from Equity. Conditionally convertible preferred stock (including stock that feature conversion rights that are either within the control of the holder or subject to conversion upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. The Company’s convertible preferred stock feature redemption rights that are considered by the Company to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, at September 30, 2021 and December 31, 2020, the convertible preferred stock subject to contingent redemption is presented as temporary equity, outside of the stockholders’ deficit section of the Company’s unaudited interim condensed consolidated balance sheets. For more information related to the redemption and conversion features of convertible preferred stock, see Note 6. Certain common stock issued to Drexel University (“Drexel”) contain put option rights whereby Drexel may, at their option, request the Company to redeem the common stock held by Drexel and at the estimated fair value of the common stock at the time of redemption. Drexel’s common stock are presented as temporary equity and subsequently remeasured to their estimated redemption value at each reporting period. Drexel’s put option right terminated immediately prior to and upon consummation of the IPO.

F-30

Acquired In-Process Research and Development Costs

Acquired in-process research and development (“IPR&D”) expense consists of the initial up-front payments incurred in connection with the acquisition or licensing of products or technologies that do not meet the definition of a business under FASB ASC Topic 805, Business Combinations. The Company’s acquired IPR&D expense of $3.1 million for the nine months ended September 30, 2021 reflects the fair value of consideration ascribed to the collaboration and licensing agreement with Integral Molecular, Inc. (“Integral”) for the development of an anti-claudin 6 (“CLDN6”) bispecific monoclonal antibody (“BsMAb”) for gynecologic cancer therapy. See Note 8 for further discussion.

Research and Development Costs

Share-Based Compensation

The Company classifies share-based compensation expense in its unaudited interim condensed consolidated statements of operations in the same manner in which the award recipients’ payroll costs are classified or in which the award recipients’ service payments are classified.

The Company estimates the fair value of employee and non-employee stock awards as of the date of grant using the Black-Scholes option pricing model. Until its IPO that closed in October 2021, the Company historically has been a private company and lacks Company-specific historical and implied volatility information. Therefore, management estimates the expected share price volatility based on the historical volatility of a publicly traded set of peer companies and expects to continue to do so until such time as it has adequate historical data regarding the volatility of its own publicly traded share price. The expected term of the Company’s stock awards has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” stock awards. The risk-free interest rate is determined by reference to the yield curve of a zero-coupon U.S. Treasury bond on the date of grant of the award for time periods approximately equal to the expected term of the award. Expected dividend yield is based on the fact that the Company has never paid cash dividends on common stock and does not expect to pay any cash dividends in the foreseeable future.

In addition, the Company measures and recognizes share-based compensation expense for advisors, officers and director restricted share-based awards based on the grant date fair value of the awards.

the Company’s outstanding convertible promissory notes, preferred stock, warrants and share-based awards, would be anti-dilutive.

The following potentially dilutive securities have been excluded from the computation of diluted weighted-average shares of common stock outstanding, as they would be anti-dilutive:


	Three Months Ended		Nine Months Ended

	5,787,116	3,644,431	5,787,116	153,273

Amounts in the above table reflect common stock equivalents.

For the nine months ended September 30, 2020, the Company used the two-class method to compute basic net income per common share. Under this method, undistributed earnings are allocated to common stock, the Series Seed Preferred Stock, and the Series A Preferred Stock to the extent that the preferred stockholders may share in earnings. In periods of net loss, losses are not allocated to participating securities as the holders of such securities have no obligation to fund losses. The total earnings allocated to common stock is then divided by the weighted average common shares outstanding to determine the basic income per share.

For purposes of calculating diluted income (loss) per common share, the denominator includes both the weighted average common shares outstanding and the number of common stock equivalents if the inclusion of such common stock equivalents would be dilutive. Dilutive common stock equivalents potentially include warrants and share-based awards using the treasury stock method. In addition, the Company considers the potential dilutive impact of its preferred stock and convertible debt using the treasury stock and if-converted methods, if either is more dilutive than the two-class method. The two-class method was more dilutive for the nine months ended September 30, 2020.

Emerging Growth Company Status

The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act, until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these condensed consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.

Recently Issued Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), in order to increase transparency and comparability among organizations by, among other provisions, recognizing lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under previous GAAP. In transition, entities may also elect a package of practical expedients that must be applied in its entirety to all leases commencing before the adoption date, unless the lease is modified, and permits entities to not reassess (a) the existence of a lease, (b) the lease classification or (c) the determination of initial direct costs, as of the adoption date, which effectively allows entities to carryforward accounting conclusions under previous GAAP. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements, which provides entities an optional transition method to apply the guidance under Topic 842 as of the adoption date, rather than as of the earliest period presented. In June 2020, the FASB issued ASU 2020-05 that further delayed the effective date of Topic 842 to fiscal years beginning

F-33

July 1, 2022, and interim periods within those years. The Company is currently evaluating the impact of adopting this guidance to its consolidated financial statements but does not believe this adoption will have a material impact due to the fact that the Company does not have any long-term lease commitments.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments, which requires measurement and recognition of expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This is different from the current guidance as this will require immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets. The new guidance will be effective for the Company on July 1, 2023. The Company is currently evaluating the impact of adopting this guidance to its consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740)—Simplifying the Accounting for Income Taxes. ASU 2019-12 simplifies the accounting for income taxes by removing exceptions within the general principles of Topic 740 regarding the calculation of deferred tax liabilities, the incremental approach for intraperiod tax allocation, and calculating income taxes in an interim period. In addition, the ASU adds clarifications to the accounting for franchise tax (or similar tax), which is partially based on income, evaluating tax basis of goodwill recognized from a business combination and reflecting the effect of any enacted changes in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. The ASU is effective for fiscal year beginning after December 15, 2021, and will be applied either retrospectively or prospectively based upon the applicable amendments. Early adoption is permitted. The Company is currently evaluating the impact of adopting this guidance to its consolidated financial statements.

(4) Fair Value Measurements

Level 1 – Observable inputs such as quoted prices in active markets.

Level 2 – Inputs, other than the quoted prices in active markets that are observable either directly or indirectly.

Level 3 – Unobservable inputs for which there is little or no market data, which require the reporting entity to develop its own assumptions.

In accordance with the fair value hierarchy described above, the following table sets forth the Company’s assets and liabilities measured at fair value on a recurring basis:


			September 30, 2021
	Total		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

Liabilities
Convertible Promissory Notes	$	5,829,292	$	—	$	—	$	5,829,292

Due to the number of embedded provisions contained in the Convertible Promissory Notes and Convertible Bridge Notes, the fair value option, as prescribed by ASC 815, Derivatives and Hedging, was elected and applied to all Convertible Promissory Note and Convertible Bridge Note issuances since the Company’s inception in 2015, in connection with the preparation of these financial statements. The fair value of the Convertible Promissory Notes and Convertible Bridge Notes was determined using a scenario-based analysis that estimated the fair value based on the probability-weighted present value of expected future investment returns, considering each of the possible outcomes available to the noteholders, including various IPO, settlement, equity financing, corporate transaction and dissolution scenarios.

The Company adjusted the carrying value of its Convertible Promissory Notes and Convertible Bridge Notes to their estimated fair value at each reporting date, with any related increases or decreases in the fair value recorded as change in fair value of convertible promissory notes in the consolidated statement of operations. The change in fair value of convertible promissory notes within the nine months ended September 30, 2021 unaudited interim condensed consolidated statement of operations also includes reversals of gains and losses previously recognized by the Company upon conversion of the notes (Note 5).

The fair value of the Senior Convertible Notes at September 30, 2020 and December 31, 2020 was calculated using an option pricing model (“OPM”) framework and utilized the back-solve method for inferring and allocating the equity value predicated on the concurrent sale of Series A Stock. This method was selected as it was concluded that the sale of the Series A Stock was an arm’s-length transaction. Application of the OPM back-solve method involves making assumptions for the expected time to liquidity and volatility, and then solving for the value of equity such that value for the most recent financing equals the amount paid.

The following table presents a roll-forward of the aggregate fair values of the Company’s Convertible Promissory Notes (Note 5) for which fair value is determined by Level 3 inputs for the periods indicated:


Balance at December 31, 2020	$	5,829,292

Junior Convertible Notes

All of the outstanding principal and accrued but unpaid interest associated with the Junior Convertible Notes converted into 2,615,553 Series Seed Stock in May 2020, of which 840,363 shares were issued to the Related Party.

At the time of conversion, the estimated fair value of the Junior Convertible Notes was $6.3 million and was reclassified to Series Seed convertible preferred equity. In connection with the conversion in 2020, the Company recorded a non-cash credit of $7.7 million related to the final decrease in fair value of the Junior Convertible Notes.

Convertible Bridge Notes

From October 2019 through March 2020, the Company issued convertible bridge notes to the Related Party in the amount of $0.5 million. The Convertible Bridge Notes bore interest at a rate of 6.0% and were set to mature on December 31, 2021 (“Maturity Date”). In the event of qualified financing resulting in gross proceeds of $1.0 million (“Bridge Note Qualified Financing”), the outstanding principal and interest of the Convertible Bridge Notes would automatically convert into Series A Stock at a price equal to the issue price per share of the stock issued in the Bridge Note Qualified Financing and on the same terms and conditions of such Bridge Note Qualified Financing. In the event that a Bridge Note Qualified Financing was not consummated prior to the Maturity Date, then, at the election of the holder made at least five days prior to the Maturity Date, effective upon the Maturity Date, the outstanding principal balance and any unpaid accrued interest under the Senior Convertible Notes was to convert into Series A Stock of the Company at a conversion price equal to 80% of the conversion price. On December 22, 2020, the outstanding principal and accrued but unpaid interest associated with the Convertible Bridge Notes converted into 78,178 shares of Series A Stock.

Due to certain embedded features within the Convertible Bridge Notes, the Company elected to account for these notes and all their embedded features under the fair value option.

At December 31, 2020, the outstanding principal balance of the Loan was approximately $124,000. In June 2020, the Paycheck Protection Program Flexibility Act was enacted, which among other things, extended the deferral period for loan payments to either (1) the date that Small Business Administration remits the borrower’s loan forgiveness amount to the lender or (2) if the borrower does not apply for loan forgiveness, ten months after the end of the borrower’s loan forgiveness covered period. The Loan was set to mature in two years and bore interest at a rate of 1.0% per year, with all payments deferred through September 5, 2021.

The entire PPP Loan was forgiven in July 2021 and recognized as a gain on extinguishment of debt within other income in the condensed consolidated statement of operations.
