ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we have filed with the Securities and Exchange Commission (the “SEC”). You should not assume that the information contained in this prospectus is accurate on any date subsequent to the date set forth on the front cover of this prospectus even though this prospectus is delivered or shares of common stock are sold or otherwise disposed of on a later date. It is important for you to read and consider all information contained in this prospectus in making your investment decision. You should also read and consider the information in the documents to which we have referred you under “Where You Can Find More Information” in this prospectus.

Neither we nor the underwriters have authorized anyone to give any information or to make any representation to you other than those contained in this prospectus. This prospectus does not constitute an offer to sell or the solicitation of an offer to buy any of our shares of common stock other than the shares of our common stock covered hereby, nor does this prospectus constitute an offer to sell or the solicitation of an offer to buy any securities in any jurisdiction to any person to whom it is unlawful to make such offer or solicitation in such jurisdiction. Persons who come into possession of this prospectus in jurisdictions outside the United States are required to inform themselves about, and to observe, any restrictions as to the offering and the distribution of this prospectus applicable to those jurisdictions.

Emerging Growth Company

We are an emerging growth company, as defined under the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). The JOBS Act provides that an emerging growth company can delay adopting new or revised accounting standards until such time as those standards apply to private companies. We cannot predict if investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.

Subject to certain conditions set forth in the JOBS Act, if, as an “emerging growth company,” we choose to rely on such exemptions we may not be required to, among other things, (i) provide an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404, (ii) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (iii) 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 reporting providing additional information about the audit and the financial statements (auditor discussion and analysis), and (iv) disclose certain executive compensation related items such as the correlation between executive compensation and performance and comparisons of the CEO’s compensation to median employee compensation.

We could remain an “emerging growth company” for up to five years, or until the earliest of (i) the last day of the first fiscal year in which our 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 and 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 $1.07 billion in non-convertible debt during the preceding three-year period.

Smaller Reporting Company

We are also currently a “smaller reporting company,” meaning that we are not an investment company, an asset-backed issuer, or a majority-owned subsidiary of a parent company that is not a smaller reporting company and have a public float of less than $250 million or annual revenues of less than $100 million during the most recently completed fiscal year. In the event that we are still considered a “smaller reporting company,” at such time we cease being an “emerging growth company,” the disclosure we will be required to provide in our SEC filings will increase, but will still be less than it would be if we were not considered either an “emerging growth company” or a “smaller reporting company.” Specifically, similar to “emerging growth companies,” “smaller reporting companies” are able to provide simplified executive compensation disclosures in their filings; are exempt from the provisions of Section 404(b) of the Sarbanes-Oxley Act

TABLE OF CONTENTS

requiring that independent registered public accounting firms provide an attestation report on the effectiveness of internal control over financial reporting; and have certain other decreased disclosure obligations in their SEC filings, including, among other things, only being required to provide two years of audited financial statements in annual reports. Decreased disclosures in our SEC filings due to our status as an “emerging growth company” or “smaller reporting company” may make it harder for investors to analyze our results of operations and financial prospects.

Presentation of Financial Information

Pursuant to the applicable provisions of the Fixing America’s Surface Transportation Act, we are omitting our financial statements for periods prior to the year ended December 31, 2019 because they relate to historical periods that we believe will not be required to be included in the prospectus at the time of the offering. We intend to amend this registration statement to include all financial information required by Regulation S-X at the date of such amendment before distributing a preliminary prospectus to investors.

The financial statements include the accounts of Acurx Pharmaceuticals, LLC and its subsidiaries. On June 23, 2021, prior to the effectiveness of the registration statement of which this prospectus forms a part, Acurx Pharmaceuticals, LLC converted into a Delaware corporation pursuant to a statutory conversion, and changed its name to Acurx Pharmaceuticals, Inc. All holders of membership interests of, or warrants to purchase membership interests of, Acurx Pharmaceuticals, LLC became holders of shares of common stock, or options or warrants to purchase shares of common stock, as applicable, of Acurx Pharmaceuticals, Inc., as described under the heading “Corporate Conversion.” In this prospectus, we refer to all transactions related to our conversion to a corporation as the Corporate Conversion.

Industry and Market Data

This prospectus includes statistical and other industry and market data that we obtained from industry publications and research, surveys and studies conducted by third parties. Industry publications and third-party research, surveys and studies generally indicate that their information has been obtained from sources believed to be reliable, although they do not guarantee the accuracy or completeness of such information.

Introduction

We are a clinical stage biopharmaceutical company developing a new class of antibiotics for infections caused by bacteria listed as priority pathogens by the World Health Organization (“WHO”), the U.S. Centers for Disease Control and Prevention (“CDC”), and the U.S. Food and Drug Administration (“FDA”). Priority pathogens are those which require new antibiotics to address the worldwide crisis of antimicrobial resistance (“AMR”), as identified by the WHO, CDC and FDA. The CDC estimates that, in the U.S., antibiotic-resistant pathogens infect one individual every 11 seconds and result in one death every 15 minutes. The WHO recently stated that growing antimicrobial resistance is equally as dangerous as the ongoing COVID-19 pandemic, threatens to unwind a century of medical progress and may leave us defenseless against infections that today can be treated easily. According to the WHO, the current clinical development pipeline remains insufficient to tackle the challenge of the increasing emergence and spread of antimicrobial resistance.

Our approach is to develop antibiotic candidates that block the DNA polymerase IIIC enzyme (“Pol IIIC”). We believe we are developing the first Pol IIIC inhibitor to enter clinical trials. Pol IIIC is the primary catalyst for DNA replication of several Gram-positive bacterial cells. Our research and development pipeline includes clinical stage and early stage antibiotic candidates that target Gram-positive bacteria for oral and/or parenteral treatment of infections caused by Clostridium difficile, Enterococcus (including vancomycin-resistant strains (“VRE”)), Staphylococcus (including methicillin-resistant strains (“MRSA”)), and Streptococcus (including antibiotic-resistant strains).

Pol IIIC is required for the replication of DNA in certain Gram-positive bacterial species. By blocking this enzyme, our antibiotic candidates are believed to be bactericidal and inhibit proliferation of several common bacterial pathogens, including both sensitive and resistant Clostridium difficile (“C. difficile”), MRSA, vancomycin resistant Enterococcus, penicillin-resistant Streptococcus pneumoniae (“PRSP”) and other resistant bacteria.

and discussed their clinical impressions. The SAB unanimously supported the early termination of the Phase 2a trial after 10 patients were enrolled in the trial instead of 20 patients as originally planned . The early termination was further based on the evidence of meeting the treatment goals of eliminating the infection with an acceptable adverse event profile.

The SAB noted that 10 out of 10 patients enrolled in the Phase 2a trial reached the Clinical Cure endpoint, defined in the study protocol as the resolution of diarrhea in the 24-hour period immediately before the end-of-treatment that is maintained for 48 hours after end of treatment. Such cure was sustained, meaning that the patients showed no sign of infection recurrence, for 30 days thereafter. This constitutes a 100% response rate for the primary and secondary endpoints of the trial. All 10 patients enrolled in the Phase 2a trial met the study's primary and secondary efficacy endpoints, namely, Clinical Cure at end of treatment and Sustained Clinical Cure of no recurrence of CDI at the 28-day follow-up visit. No treatment-related serious adverse events (“SAEs”) were reported by the investigators who enrolled patients in the trial. We believe these results represent the first-ever clinical data showing Pol IIIC has potential as a therapeutically-relevant antibacterial target. We plan to commence a Phase 2b clinical trial pursuant to the trial design described below.

The SAB is comprised of nine scientists and clinicians who have significant expertise in the scientific disciplines required for the research and development of antibiotics. The members of the SAB serve at the pleasure of management, are paid in cash on an hourly basis for their services and do not receive equity compensation. Generally, the SAB is consulted by management during the process of designing our preclinical and clinical trials as well as in the process of analyzing data generated from these trials, although the SAB’s services are not limited to such activities.

Currently-available antibiotics used to treat CDI infections utilize other mechanisms of action. We believe ibezapolstat is the first antibiotic candidate to work by blocking the DNA Pol IIIC enzyme in C. difficile. This enzyme is necessary for replication of the DNA of certain Gram-positive bacteria, like C. difficile.

We also have an early stage pipeline of antibiotic product candidates with the same previously unexploited mechanism of action which has established proof of concept in animal studies. This pipeline includes ACX-375C, a potential oral and parenteral treatment targeting Gram-positive bacteria, including MRSA, VRE and PRSP.

Market Opportunity

C. Difficile Infection

According to the 2017 Update (published February 2018) of the Clinical Practice Guidelines for Clostridium difficile Infectionin Adults and Children by the Infectious Diseases Society of America (IDSA) and Society of Healthcare Epidemiology of America (SHEA), CDI remains a significant medical problem in hospitals, in long-term care facilities and in the community. Clostridioides (formerly Clostridium) difficile, also known as C. difficile or C. diff, is one of the most common causes of healthcare-associated infections in U.S. hospitals (Lessa, et al, 2015, New England Journal of Medicine). Recent estimates suggest C. difficile approaches 500,000 infections annually in the U.S. and is associated with approximately 20,000 deaths. (Guh, 2020, New England Journal of Medicine). Based on internal estimates, including a recurrence rate of between 20% and 40% among approximately 150,000 patients treated, we believe that the annual incidence in the U.S. approaches 600,000 infections and a mortality rate of approximately 9.3%.

Antibiotics are the gold standard to treat CDI. However, while currently marketed antibiotics achieve a relatively high initial cure rate, they can fail to eliminate C. difficile, especially drug-resistant strains, in the gut, allowing the continued growth of the bacteria. This, together with a pronounced detrimental effect on the gut microbiome, leads to recurrence in over 25% of CDI patients after therapy is stopped. A significant unmet need remains for antibiotics that can meaningfully reduce recurrence. According to our recent clinical data, we believe ibezapolstat has the potential to continue to provide a bactericidal effect combined with a low incidence of recurrence when used to treat CDI.

antibodies as a first-line treatment, antibodies have gained limited commercial traction and there has only been one antibody treatment for CDI approved to date. As of the date of this prospectus, there are currently two microbiologics in late-stage development with clinical data forthcoming. Safety is a concern with microbiologics, and this course of treatment is only recommended for patients with multiple recurrences of CDI who have failed appropriate antibiotic treatments. There are also several vaccines against C. difficile in late-stage development, but none are currently approved. A vaccine is only likely to be commercially viable as a prevention of recurrent CDI in high-risk patients, if such patients can be identified. Additionally, large numbers of patients are required for clinical trials of vaccines, which could significantly delay the clinical development process for and eventual release of any CDI vaccine products currently in development.

MRSA, VRE and PRSP

In its 2019 update, the CDC further reported that more than 2.8 million antibiotic-resistant infections occur in the U.S. each year and more than 35,000 people die as a result, nearly twice as many annual deaths than previously reported by CDC in 2013. These deaths are attributed to antimicrobial-resistant pathogens including Enterococcus (including vancomycin-resistant strains or VRE), Staphylococcus (including MRSA), and Streptococcus (including antibiotic-resistant strains) which are the targets of our second antibiotic candidate currently in preclinical development. In hospitalized patients, MRSA accounted for 52% of all infections, which is almost twice as many as multidrug resistant Gram-negative infections.

ACX-375C, our second antibiotic candidate, is in preclinical development and, specifically, is at the point where we are optimizing the lead compound. The goal of lead optimization, which is part of the preclinical stage of development, is to identify and synthesize compounds with the best potency while demonstrating improvements in (1) aqueous solubility, (2) plasma protein binding and (3) cytotoxicity.

ACX- 375C has demonstrated potent activity against clinically important pathogens including minimum inhibitory concentration values (“MIC values”), of 1 to 4 µg/mL against MRSA, VRE and PRSP. Further characterization and testing in animal models are ongoing. Management believes that potential clinical indications of the efficacy of ACX-375C include infections that can impact the urinary tract, hospital acquired catheter/blood stream, intra-abdominal areas, skin/soft tissues, bones/joints, pneumonia, and ear/sinus infections. These bacterial targets involve an estimated incidence of approximately six million patients per year in the U.S. alone. Based on a review of other antibiotics currently marketed to treat these bacterial infections, our early estimate of peak year sales potential is based on 4% to 5% of this annual incidence and a peak year sales potential of $1 billion. This drug can help fill an unmet medical need because drugs currently used, such as daptomycin and linezolid-resistant bacteria, experience antibiotic resistance. (Wei-Chu Xu, et al., Bioorganic & Medicinal Chemistry https://doi.org/10.1016/j.bmc.2019.06.017).

Our Competitive Strengths

We attribute our success to the following competitive strengths:

•

We have a novel mechanism of action which we believe will be highly advantageous given the continuing rate of recurrent CDI with currently available treatment options and the rising prevalence of antimicrobial resistance.

•

Since ibezapolstat’s molecular structure and mechanism of action are unrelated to any other antimicrobial chemical class, its use is not expected to foster the emergence of bacteria that are resistant to other classes of antibiotics.

•

The Phase 1 Trial showed highly selective activity against C. difficile bacteria with minimal disruption to the gut flora as it is poorly soluble which has been corroborated by the data from the microbiome analysis.

•

As of the date of this prospectus, ibezapolstat has shown an excellent human safety profile.

Our designation by the FDA of Qualified Infectious Disease (“QIDP”) status and Fast Track designation provides significant benefits to our development of ibezapolstat. We have significant existing patent coverage in the world’s largest pharmaceutical markets (U.S., Europe, Japan and Canada) extending to September 2030 in the United States and September 2030 in foreign markets. There is also the possibility to

TABLE OF CONTENTS

extend those patents thereafter. We also have a simple and low-cost process of manufacturing which is expected to yield cost of goods of less than 5% of the anticipated retail price.

Risks Associated With Our Business

Our business is subject to a number of risks and uncertainties that you should understand before making an investment decision. Risks are discussed more fully in the section entitled “Risk Factors” of this prospectus. These risks include, but are not limited to, the following:

Risks Related to Our Business

•

We have a very limited operating history and are expected to incur significant operating losses during the early stage of our corporate development.

•

We are reliant on the success of our lead product candidate, ibezapolstat, which we are developing for the treatment of CDI. If we are unable to commercialize ibezapolstat, or experience significant delays in doing so, our business will be materially harmed.

•

If serious adverse or inappropriate side effects are identified during the development of ibezapolstat or any other product candidate, we may need to abandon or limit our development of that product candidate.

•

Ibezapolstat or our other product candidates may never achieve sufficient market acceptance even if we obtain regulatory approval.

•

We are exposed to product liability, and non-clinical and clinical liability risks which could place a substantial financial burden upon us, should lawsuits be filed against us.

•

We are not currently profitable and may never become profitable.

•

Our current and future operations substantially depend on our management team and our ability to hire other key personnel, the loss of any of whom could disrupt our business operations.

•

Our failure to complete or meet key milestones relating to the development of our technologies and proposed products and formulations would significantly impair our financial condition.

•

We will compete with larger and better capitalized companies, and competitors in the drug development or pharmaceutical industries may develop competing products which outperform or supplant our proposed products.

•

We will incur increased costs as a result of being a public company.

•

The insurance coverage and reimbursement status of newly approved products is uncertain. Failure to obtain or maintain adequate coverage and reimbursement for new or current products could limit our ability to market those products and decrease our ability to generate revenue.

Risks Related to Regulatory Approval

•

If clinical trials of our lead product candidate fail to demonstrate safety and efficacy to the satisfaction of the FDA, or the European Medicines Agency (the “EMA”), or do not otherwise produce favorable results, we may incur additional costs or experience delays in completing, or ultimately be unable to complete the development and commercialization of ibezapolstat or any other product candidate.

•

If we experience any of a number of possible unforeseen events in connection with our clinical trials, potential marketing approval or commercialization of our product candidates could be delayed or prevented.

•

If we experience delays or difficulties in the enrollment of patients in our clinical trials, our receipt of necessary marketing approvals could be delayed or prevented.

•

Our failure to obtain costly government approvals, including required FDA approvals, or to comply with ongoing governmental regulations relating to our proposed products and formulations could

TABLE OF CONTENTS

delay or limit introduction of our proposed formulations and products and result in failure to achieve revenues or maintain our ongoing business.

•

Our results of operations may be adversely affected by current and potential future healthcare legislative and regulatory actions.

Risks Related to Our Dependence on Third Parties

•

If we are unable to establish sales and marketing capabilities or enter into agreements with third parties to market and sell our product candidates, we may not be successful in commercializing ibezapolstat or any other product candidate if and when such product candidates are approved.

•

We contract with third parties for the manufacture of our product candidates for preclinical studies and our ongoing clinical trials, and expect to continue to do so for additional clinical trials and ultimately for commercialization. This reliance on third parties increases the risk that we will not have sufficient quantities of our product candidates or drugs or such quantities at an acceptable cost, which could delay, prevent or impair our development or commercialization efforts.

•

If ultimate users of our product candidates are unable to obtain adequate reimbursement from third- party payers, or if new restrictive legislation is adopted, market acceptance of our proposed products may be limited and we may not achieve material revenues.

Risks Related to Intellectual Property

•

We may be involved in lawsuits to protect or enforce our patents.

•

Intellectual property litigation could cause us to spend substantial resources and distract our personnel from their normal responsibilities.

•

We may need to license certain intellectual property from third parties, and such licenses may not be available or may not be available on commercially reasonable terms.

•

If we are unable to adequately protect or enforce our rights to intellectual property or secure rights to third-party patents, we may lose valuable rights, experience reduced market share, assuming any, or incur costly litigation to enforce, maintain or protect such rights.

•

Third party intellectual property rights, including patents, may affect or even block our ability to commercialize our future products in one or more countries. Third parties may sue us for infringing their patents. Defending such lawsuit would be costly and in the event of a successful claim of infringement against us, we may be required to:

•

pay substantial damages;

•

stop using our technologies and methods;

•

stop certain research and development efforts;

•

try to develop non-infringing products or methods; and

•

obtain one or more licenses from third parties.

Risks Related to this Offering and Ownership of Our Common Stock

•

We may need substantial additional funding. If we are unable to raise capital when needed, we could be forced to delay, reduce or eliminate our product development programs or commercialization efforts.

•

Because we do not anticipate paying any cash dividends on our common stock in the foreseeable future, capital appreciation, if any, will be your sole source of gain.

•

Our largest stockholders will exercise significant influence over our company for the foreseeable future, including the outcome of matters requiring stockholder approval.

•

Our common stock has no prior public market, and we cannot assure you that an active trading market will develop.

TABLE OF CONTENTS

Corporate Conversion

On June 23, 2021, prior to the effectiveness of the registration statement of which this prospectus forms a part, Acurx Pharmaceuticals, LLC converted from a Delaware limited liability company into a Delaware corporation pursuant to a statutory conversion, and changed its name to Acurx Pharmaceuticals, Inc. In this prospectus, we refer to all transactions related to our conversion to a corporation as the Corporate Conversion. As a result of the Corporate Conversion, all holders of membership interests of Acurx Pharmaceuticals, LLC became holders of shares of common stock of Acurx Pharmaceuticals, Inc. As a result of the corporate conversion:

•

all of the Class A membership interests and all of the Class B membership interests of Acurx Pharmaceuticals, LLC became shares of common stock of Acurx Pharmaceuticals, Inc. pursuant to a conversion ratio of one-half of one share of common stock of Acurx Pharmaceuticals, Inc. for each Class A membership interest or Class B membership interest of Acurx Pharmaceuticals, LLC previously held. Accordingly, 13,750,908 Class A membership interests and 100,000 Class B membership interests of Acurx Pharmaceuticals, LLC issued and outstanding immediately prior to the corporate conversion converted automatically into an aggregate of approximately 6,925,454 shares of common stock of Acurx Pharmaceuticals, Inc. (excluding rounding for fractional shares) as of May 25, 2021;

•

all of the outstanding warrants to purchase Class A membership interests of Acurx Pharmaceuticals, LLC became warrants to purchase shares of common stock of Acurx Pharmaceuticals, Inc. at a ratio of one-half of one share of common stock of Acurx Pharmaceuticals, Inc. for each Class A membership interest of Acurx Pharmaceuticals, LLC underlying such warrants, with the effect that warrants to purchase up to an aggregate of 2,875,119 Class A membership interests of Acurx Pharmaceuticals, LLC outstanding immediately prior to the corporate conversion automatically converted into warrants to purchase up to an aggregate of approximately 1,437,559 shares of common stock of Acurx Pharmaceuticals, Inc.; and

•

the exercise price of all of the outstanding warrants to purchase Class A membership interests of Acurx Pharmaceuticals, LLC was adjusted in the same ratio as the one-half-for-one conversion ratio for outstanding warrants to purchase Class A membership interests of Acurx Pharmaceuticals, LLC noted above such that all of our outstanding warrants to purchase Class A membership interests of Acurx Pharmaceuticals, LLC which were previously exercisable at a weighted average price of $1.44 per Class A membership interest automatically adjusted such that the new exercise price for the warrants to purchase shares of common stock of Acurx Pharmaceuticals, Inc. that are outstanding is at a weighted average price of $2.88 per share, subject to certain adjustment provisions included in each such warrant.

The purpose of the Corporate Conversion was to reorganize our structure so that the entity that is offering our common stock to the public in this offering is a corporation rather than a limited liability company and so that our existing investors own our common stock rather than equity interests in a limited liability company. For further information regarding the Corporate Conversion, see “Corporate Conversion.”

Recent Developments

Effects of Coronavirus on Our Business

The World Health Organization recognized COVID-19 as a public health emergency of international concern on January 30, 2020 and as a global pandemic on March 11, 2020. Public health responses have included national pandemic preparedness and response plans, travel restrictions, quarantines, curfews, event postponements and cancellations and closures of facilities including local schools and businesses. The global pandemic and actions taken to contain COVID-19 have adversely affected the global economy and financial markets.

TABLE OF CONTENTS

COVID-19 pandemic has highlighted the importance of antibiotic development in responding to global health issues particularly because many hospitalized COVID-19 patients were also prescribed antibiotics which only accelerates the current antimicrobial resistance crisis described by several regulatory bodies worldwide.

The extent to which the COVID-19 pandemic will ultimately impact our business, results of operations, financial condition and cash flows depends on future developments that are highly uncertain, rapidly evolving and difficult to predict at this time. While we are not experiencing material adverse impacts at this time, given the global economic slowdown, the overall disruption of global supply chains and distribution systems and the other risks and uncertainties associated with the COVID-19 pandemic, our business, financial condition, results of operations and growth prospects could be materially and adversely affected. While we believe that we are well positioned for the future as we navigate the crisis and prepare for an eventual return to a more normal operating environment, we continue to closely monitor the COVID-19 pandemic as we evolve our business continuity plans and response strategy.

In May 2020, we received a Paycheck Protection Program loan (“PPP Loan”) under the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), as administered by the U.S. Small Business Administration (”SBA”) in the amount of $66,503. We did not provide any collateral or guarantees in connection with the PPP Loan, nor did we pay any facility charge to obtain the PPP Loan. The note and agreement provides for customary events of default, including those relating to failure to make payment, bankruptcy, breaches of representations and material adverse effects. We may prepay the principal of the PPP Loan at any time without incurring any prepayment charges. The PPP Loan carries an annual interest rate of 0.98% and matures two (2) years from issuance.

On April 13, 2021, the SBA authorized the full forgiveness of the PPP Loan. Upon forgiveness of the PPP Loan, we will reduce the liability and record a gain on extinguishment of debt in the statement of operations.

TABLE OF CONTENTS

RISK FACTORS

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below, together with all of the other information in this prospectus, including our financial statements and notes thereto, before deciding whether to invest in our common stock. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that affect us. If any of the following risks occur, our business, operating results and prospects could be materially harmed. In that event, the price of our common stock could decline, and you could lose part or all of your investment.

Risks Relating to Our Business

We have a very limited operating history and are expected to incur significant operating losses during the early stage of our corporate development.

We were organized in July 2017 and we acquired the rights to our lead product candidate, ibezapolstat, in February 2018. We have a limited operating history. Our operations to date have been limited to securing our initial product candidate, generating a second product candidate in-house, conducting clinical and regulatory development for our lead program and raising capital.

Investing in an early-stage company with limited history, financial or otherwise, includes a high degree of risk. As an early-stage company, our prospects must be considered in light of the uncertainties, risks, expenses, and difficulties frequently encountered by companies in their early stages of operations. We have generated losses since inception and we expect to continue to run at a loss for several years until our initial program, or one of our pipeline products, is approved by the FDA or another worldwide regulatory body. We expect to incur substantial operating expenses over the next several years as our product development activities and related costs increase. No assurance can be given that we will be able to successfully implement any or all of our business plan, or if implemented, that we will accomplish the desired objectives, including achieving profitability.

Our independent registered public accounting firm has expressed substantial doubt about our ability to continue as a going concern.

Our independent registered public accounting firm noted in its report accompanying our financial statements for the fiscal year ended December 31, 2020 that we had suffered significant accumulated deficit and had negative operating cash flows and that the development and commercialization of our product candidates are expected to require substantial expenditures. We have not yet generated any material revenues from our operations to fund our activities, and are therefore dependent upon external sources for financing our operations. There can be no assurance that we will succeed in obtaining the necessary financing to continue our operations. As a result, our independent registered public accounting firm has expressed substantial doubt about our ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. If we cannot successfully continue as a going concern, our stockholders may lose their entire investment in our common stock.

Our ability to generate product revenues, which may not occur for several years, if ever, currently depends heavily on the successful development and commercialization of ibezapolstat. The success of ibezapolstat will depend on a number of factors, including the following:

•

successful completion of clinical development;

•

receipt of marketing approvals from applicable regulatory authorities;

•

establishing commercial manufacturing arrangements with third-party manufacturers;

•

obtaining and maintaining patent and trade secret protection and regulatory exclusivity;

TABLE OF CONTENTS

•

protecting our rights in our intellectual property portfolio;

•

establishing sales, marketing and distribution capabilities;

•

launching commercial sales of ibezapolstat, if and when approved, whether alone or in collaboration with others;

•

acceptance of ibezapolstat, if and when approved, by patients, the medical community and third-party payors;

•

effectively competing with other CDI therapies; and

•

maintaining a continued acceptable safety profile of ibezapolstat following approval.

If we do not achieve one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully commercialize ibezapolstat, which would materially harm our business.

We have not yet demonstrated our ability to successfully complete development of any product candidates, obtain marketing approvals, manufacture a commercial scale product, or arrange for a third party to do so on our behalf, or conduct sales and marketing activities necessary for successful product commercialization. Assuming we obtain marketing approval for any of our product candidates, we will need to transition our focus from research and development to supporting commercial activities. We may encounter unforeseen expenses, difficulties, complications and delays and may not be successful in such a transition.

Our product candidates are in clinical development and its risk of failure is high. It is impossible to predict when our product candidates will prove effective or safe in humans or will receive marketing approval. If our product candidates are associated with undesirable side effects or have characteristics that are unexpected, we may need to abandon their development or limit development to certain uses or subpopulations in which the undesirable side effects or other characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective.

Many compounds that initially show promise in clinical or earlier stage testing have later been found to cause side effects or other safety issues that prevented further development. If we elect or are forced to suspend or terminate any clinical trial of our product candidates, the commercial prospects of such product candidate will be harmed and our ability to generate product revenues from such product candidate will be delayed or eliminated. Any of these occurrences could materially harm our business.

Ibezapolstat or our other product candidates may never achieve sufficient market acceptance even if we obtain regulatory approval.

If ibezapolstat or any of our other future product candidates receive marketing approval, such products may nonetheless fail to gain sufficient market acceptance by physicians, patients, third-party payors and others in the medical community. If these products do not achieve an adequate level of acceptance, we may not generate significant product revenues or revenue from collaboration agreements or any profits from operations. The degree of market acceptance of our product candidates, if approved for commercial sale, will depend on a number of factors, including:

•

the efficacy and potential advantages compared to alternative treatments or competitive products;

•

the prevalence and severity of any side effects;

•

the ability to offer our product candidates for sale at competitive prices;

•

convenience and ease of administration compared to alternative treatments;

•

the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies;

TABLE OF CONTENTS

•

obtaining regulatory clearance of marketing claims for the uses that we are developing;

•

our ability to timely and effectively manufacture, market and distribute our products, either on our own or through third parties;

•

pricing and reimbursement policies of government and third-party payers such as insurance companies, health maintenance organizations and other health plan administrators;

•

the timing of any such marketing approval in relation to other product approvals;

•

support from patient advocacy groups;

•

our ability to attract corporate partners, including pharmaceutical companies, to assist in commercializing our proposed formulations or products; and

•

any restrictions on concomitant use of other medications.

If our products do not achieve an adequate level of acceptance by the relevant constituencies, or adequate pricing, we may not generate significant product revenue and may not become profitable.

We are exposed to product liability, and non-clinical and clinical liability risks which could place a substantial financial burden upon us, should lawsuits be filed against us.

Our business exposes us to potential product liability and other liability risks that are inherent in the testing, manufacturing and marketing of pharmaceutical formulations and products. We expect that such claims are likely to be asserted against us at some point, although we do carry product liability and clinical trial insurance to mitigate this risk. In addition, the use in our clinical trials of pharmaceutical formulations and products and the subsequent sale of these formulations or products by us or our potential collaborators may cause us to bear a portion of or all product liability risks. A successful liability claim or series of claims brought against us could have a material adverse effect on our business, financial condition and results of operations.

We are not currently profitable and may never become profitable.

We expect to incur substantial losses and negative operating cash flow for the foreseeable future, and we may never achieve or maintain profitability. Even if we are able to launch our product candidate, this will not occur for several years, if at all.

We also expect to experience negative cash flow for the foreseeable future as we fund our operating losses and capital expenditures. As a result, we will need to generate significant revenues in order to achieve and maintain profitability. We may not be able to generate these revenues or achieve profitability in the future. Our failure to achieve or maintain profitability would negatively impact the value of your common stock and potentially require us to shut down our business, which would result in the loss of your investment.

Our current and future operations substantially depend on our management team and our ability to hire other key personnel, the loss of any of whom could disrupt our business operations.

Our business does and will depend in substantial part on the continued services of David P. Luci, Robert J. DeLuccia and Robert G. Shawah. The loss of the services of any of these individuals would significantly impede implementation and execution of our business strategy and result in the failure to reach our goals. We do not carry key person life insurance on any member of our management, which would leave us uncompensated for the loss of any member of our management.

Our future financial condition and ability to achieve profitability will also depend on our ability to attract, retain and motivate highly qualified personnel in the diverse areas required for continuing our operations. There is a risk that we will be unable to attract, retain and motivate qualified personnel, both near term or in the future, and our failure to do so may severely damage our prospects.

Our failure to complete or meet key milestones relating to the development of our technologies and proposed products and formulations would significantly impair our financial condition.

In order to be commercially viable, we must research, develop and obtain regulatory approval to manufacture, introduce, market and distribute formulations or products incorporating our technologies. For each drug that we formulate, we must meet a number of critical developmental milestones, including:

TABLE OF CONTENTS

•

demonstration of the benefit of each specific drug through our drug delivery technologies;

•

demonstration, through non-clinical and clinical trials, that our drug delivery technologies are safe and effective; and

•

establishment of a viable current good manufacturing process (“cGMP”) capable of potential scale-up.

The estimated required capital and time-frames necessary to achieve these developmental milestones is subject to inherent risks, many of which are beyond our control. As such, we may not be able to achieve these or similar milestones for any of our proposed product candidates or other product candidates in the future. Our failure to meet these or other critical milestones would adversely affect our financial condition.

Conducting and completing the clinical trials necessary for FDA approval is costly and subject to intense regulatory scrutiny as well as the risk of failing to meet the primary endpoint of such trials. We will not be able to commercialize and sell our proposed products and formulations without completing such trials.

In order to conduct clinical trials that are necessary to obtain approval by the FDA to market a formulation or product, it is necessary to receive clearance from the FDA to conduct such clinical trials. The FDA can halt clinical trials at any time for safety reasons or because we or our clinical investigators did not follow the FDA’s requirements for conducting clinical trials. If we are unable to receive clearance to conduct clinical trials or the trials are permanently halted by the FDA, we would not be able to achieve any revenue from such product as it is illegal to sell any drug or medical device for human consumption or use without FDA approval. Moreover, there is a risk that our clinical trials will fail to meet their primary endpoints, which would make them unacceptable in having the subject product approved by the FDA. If this were to occur, such event would materially and adversely affect our business, results of operations and financial condition.

Drug companies and/or other technology companies have developed (and are currently marketing in competition with us), have sought to develop and may in the future seek to develop and market similar product candidates and drug delivery technologies which may become more accepted by the marketplace or which may supplant our technology entirely. In addition, many of our current competitors are, and future competitors may be, significantly larger and better financed than we are, thus giving them a significant advantage over us. Our competitors may also have significantly greater expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved products than we do. These competitors also compete with us in recruiting and retaining qualified scientific advisors and consultants as well as management personnel and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs. Other small or early stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. We may be unable to respond to competitive forces presently in the marketplace which would severely impact our business.

We may not be able to effectively manage our growth and expansion or implement our business strategies, in which case our business and results of operations may be materially and adversely affected.

The expected growth of our business, if it occurs, will place increased demands on our management, operational and administrative resources. These increased demands and operating complexities could cause us to operate our business less effectively which, in turn, could cause a deterioration in our financial performance and negatively impact our growth. Any planned growth will also require that we continually monitor and upgrade our management information and other systems, as well as our infrastructure.

There can be no assurance that we will be able to grow our business and achieve our goals. Even if we succeed in establishing new strategic partnerships, we cannot assure that we will achieve planned revenue or profitability levels in the time periods estimated by us, or at all. If any of these initiatives fails to achieve or is unable to sustain acceptable revenue and profitability levels, we may incur significant costs.

TABLE OF CONTENTS

The outbreak of the novel coronavirus disease, COVID-19, could adversely impact our business, including our preclinical studies and clinical trials.

The global coronavirus pandemic has resulted in widespread requirements for individuals to stay in their homes and strained medical facilities worldwide. It is too early to assess the full impact of the coronavirus outbreak on our business, but coronavirus may affect our ability to complete recruitment and data analysis for our clinical trials and our ability to conduct research and development of our complement programs in our planned timeframe. The extent to which the coronavirus impacts our operations will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the duration and severity of the outbreak, and the actions that may be required to contain the coronavirus or treat its impact. In particular, as a result of the COVID-19 pandemic, we may experience disruptions that could severely impact our business, preclinical studies, drug manufacturing and clinical trials including:

•

delays or difficulties in enrolling potential trial participants in our clinical trials;

•

delays or difficulties in clinical site initiation, including difficulties in recruiting clinical site investigators and clinical site staff;

•

diversion of healthcare resources away from the conduct of clinical trials;

•

interruption of key clinical trial activities, such as clinical trial site data monitoring, due to limitations on travel imposed or recommended by federal or state governments, employers and others or interruption of clinical trial subject visits and study procedures, which may impact the integrity of subject data and clinical study endpoints;

•

interruption or delays in the operations of the Food and Drug Administration, European Medicines Agency or other regulatory authorities, which may impact review and approval timelines;

•

interruption of, or delays in receiving, supplies of our product candidates from our contract manufacturing organizations due to staffing shortages, production slowdowns or stoppages and disruptions in delivery systems;

•

interruptions in preclinical studies due to restricted or limited operations at laboratory facilities;

•

suspension or termination of our clinical trials for various reasons, such as a finding that the participants are being exposed to infectious diseases like COVID-19 or the participants involved in our clinical trials have become infected with COVID-19;

•

limitations on employee resources that would otherwise be focused on the conduct of our preclinical studies and clinical trials, including because of sickness of employees or their families or the desire of employees to avoid contact with large groups of people; and

•

material delays and complications with respect to our research and development programs.

Furthermore, a recession or market correction resulting from the spread of COVID-19 could materially affect our operations and the value of our common stock.

We will incur increased costs as a result of being a public company.

As a public company, we will incur significant legal, accounting, insurance and other expenses that we did not incur as a private company. For example, we will incur increased legal and accounting costs as a result of being subject to the information and reporting requirements of the Exchange Act, and other federal securities laws. The costs of preparing and filing periodic and other reports, proxy statements and other information with the SEC and furnishing audited reports to stockholders, will cause significant increase in our expenses than if we remained privately-held. The cost of being a public company will divert resources that might otherwise have been used to develop our business, which could have a material adverse effect on our company.

As a privately held company, we have not been required to comply with certain corporate governance and financial reporting practices and policies required of a public reporting company. If the registration statement of which this prospectus forms a part is declared effective, as a public company, we will be required

TABLE OF CONTENTS

to file with the SEC annual and quarterly information and other reports pursuant to the Exchange Act. We will also be required to ensure that we have the ability to prepare financial statements that are fully compliant with all SEC reporting requirements on a timely basis. In addition, we may become subject to other reporting and corporate governance requirements, including the requirements of any national securities exchange on which our common stock is listed, should we so qualify for listing, and certain provisions of the Sarbanes-Oxley Act of 2002, as amended (the “Sarbanes-Oxley Act”), and the regulations promulgated thereunder, which will impose significant compliance obligations upon us. As a public company, we will, among other things:

•

prepare and distribute periodic public reports and other stockholder communications in compliance;

•

comply with our obligations under the federal securities laws and applicable listing rules;

•

create or expand the roles and duties of our board of directors and committees of the board of directors;

•

institute more comprehensive financial reporting and disclosure compliance functions;

•

enhance our investor relations function;

•

establish new internal policies, including those relating to disclosure controls and procedures; and

•

involve and retain to a greater degree outside counsel and accountants in the activities listed above.

These changes will require a significant commitment of additional resources and many of our competitors already comply with these obligations. We may not be successful in complying with these obligations and the significant commitment of resources required for complying with them could have a material adverse effect on our business, financial condition and results of operations. 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 committees of our board of directors or as our executive officers.

In addition, if we fail to implement the requirements with respect to our internal accounting and audit functions, our ability to report our results of operations on a timely and accurate basis could be impaired and we could suffer adverse regulatory consequences or violate applicable listing standards. There could also be a negative reaction in the financial markets due to a loss of investor confidence in us and the reliability of our financial statements, which could have a material adverse effect on our business, financial condition and results of operations.

The changes necessitated by becoming a public company require a significant commitment of resources and management supervision that has increased and may continue to increase our costs and might place a strain on our systems and resources. As a result, our management’s attention might be diverted from other business concerns. If we fail to maintain an effective internal control environment or to comply with the numerous legal and regulatory requirements imposed on public companies, we could make material errors in, and be required to restate, our financial statements. Any such restatement could result in a loss of public confidence in the reliability of our financial statements and sanctions imposed on us by the SEC. We cannot predict or estimate the amount of additional costs we may incur or the timing of such costs. If we are unable to satisfy our obligations as a public company, we could be subject to delisting of our common stock, as applicable, fines, sanctions and other regulatory action and potentially civil litigation.

The availability and extent of reimbursement by governmental and private payors is essential for most patients to be able to afford expensive treatments. Sales of our product candidates will depend substantially, both domestically and abroad, on the extent to which the costs of our product candidates will be paid by health maintenance, managed care, pharmacy benefit and similar healthcare management organizations, or reimbursed by government health administration authorities, private health coverage insurers and other

TABLE OF CONTENTS

third-party payors. If reimbursement is not available, or is available only to limited levels, we may not be able to successfully commercialize our product candidates. Even if coverage is provided, the approved reimbursement amount may not be high enough to allow us to establish or maintain pricing sufficient to realize a sufficient return on our investment.

There is significant uncertainty related to the insurance coverage and reimbursement of newly approved products. Moreover, increasing efforts by governmental and third-party payors, in the U.S. and abroad, to cap or reduce healthcare costs may cause such organizations to limit both coverage and level of reimbursement for new products approved and, as a result, they may not cover or provide adequate payment for our product candidates. We expect to experience pricing pressures in connection with the sale of any of our product candidates, due to the trend toward managed healthcare, the increasing influence of health maintenance organizations and additional legislative changes. The downward pressure on healthcare costs in general has become very intense. As a result, increasingly high barriers are being erected to the entry of new products.

Because results of preclinical studies and early clinical trials are not necessarily predictive of future results, any product candidate we advance may not have favorable results in later clinical trials or receive regulatory approval. Moreover, interim, “top-line,” and preliminary data from our clinical trials that we announce or publish may change, or the perceived product profile may be negatively impacted, as more patient data or additional endpoints (including efficacy and safety) are analyzed.

Pharmaceutical development has inherent risks. The outcome of preclinical development testing and early clinical trials may not be predictive of the outcome of later clinical trials, and interim results of a clinical trial do not necessarily predict final results. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval of their product candidates. Once a product candidate has displayed sufficient preclinical data to warrant clinical investigation, we will be required to demonstrate through adequate and well-controlled clinical trials that our product candidates are effective with a favorable benefit-risk profile for use in populations for their target indications before we can seek regulatory approvals for their commercial sale. Many drug candidates fail in the early stages of clinical development for safety and tolerability issues or for insufficient clinical activity, despite promising pre-clinical results. Accordingly, no assurance can be made that a safe and efficacious dose can be found for these compounds or that they will ever enter into advanced clinical trials alone or in combination with other product candidates. Moreover, success in early clinical trials does not mean that later clinical trials will be successful because product candidates in later-stage clinical trials may fail to demonstrate sufficient safety or efficacy despite having progressed through initial clinical testing. Companies frequently experience significant setbacks in advanced clinical trials, even after earlier clinical trials have shown promising results. There is an extremely high rate of failure of pharmaceutical candidates proceeding through clinical trials.

Individually reported outcomes of patients treated in clinical trials may not be representative of the entire population of treated patients in such studies. In addition, larger scale Phase 3 studies, which are often conducted internationally, are inherently subject to increased operational risks compared to earlier stage studies, including the risk that the results could vary on a region to region or country to country basis, which could materially adversely affect the outcome of the study or the opinion of the validity of the study results by applicable regulatory agencies.

From time to time, we may publicly disclose top-line or preliminary data from our clinical trials, which is based on a preliminary analysis of then available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular study or trial. We also make assumptions, estimations, calculations and conclusions as part of our analyses of such data, and we may not have received or had the opportunity to fully and carefully evaluate all data from the particular study or trial, including all endpoints and safety data. As a result, top-line or preliminary results that we report may differ from future results of the same studies, or different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated. Top-line or preliminary data also remain subject to audit and verification procedures that may result in the final data being materially different from the topline, interim, or preliminary data we previously published. When providing

TABLE OF CONTENTS

top-line results, we may disclose the primary endpoint of a study before all secondary endpoints have been fully analyzed. A positive primary endpoint does not translate to all, or any, secondary endpoints being met. As a result, top-line and preliminary data should be viewed with caution until the final data are available, including data from the full safety analysis and the final analysis of all endpoints.

Further, from time to time, we may also disclose interim data from our preclinical studies and clinical trials. 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. For example, time-to-event based endpoints such as duration of response (“DOR”) and PFS have the potential to change, sometimes drastically, with longer follow-up. In addition, as patients continue on therapy, there can be no assurance given that the final safety data from studies, once fully analyzed, will be consistent with prior safety data presented, will be differentiated from other similar agents in the same class, will support continued development, or will be favorable enough to support regulatory approvals for the indications studied. Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of the particular product candidate or product and our company in general. The information we choose to publicly disclose regarding a particular study or clinical trial is based on what is typically extensive information, and regulators or others may not agree with what we determine is material or otherwise appropriate information to include in our disclosure. If the interim, top-line or preliminary data that we report differ from final results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, or successfully commercialize, our product candidates may be harmed, which could harm our business, operating results, prospects or financial condition.

Risks Related to Regulatory Approval

If clinical trials of our lead product candidate fail to demonstrate safety and efficacy to the satisfaction of the FDA, or the EMA, or do not otherwise produce favorable results, we may incur additional costs or experience delays in completing, or ultimately be unable to complete the development and commercialization of ibezapolstat or any other product candidate.

In connection with obtaining marketing approval from regulatory authorities for the sale of any product candidate, we must complete extensive clinical trials to demonstrate the safety and efficacy of our product candidates in humans. Clinical testing is expensive, difficult to design and implement, can take many years to complete and is uncertain as to outcome. A failure of one or more clinical trials can occur at any stage of testing. The outcome of preclinical testing and early clinical trials, particularly with a small number of patients, may not be predictive of the success of later clinical trials, and interim results of a clinical trial do not necessarily predict final results. The design of a clinical trial can determine whether its results will support approval of a product, and flaws in the design of a clinical trial may not become apparent until the clinical trial is well advanced or completed. We have limited experience in designing clinical trials and may be unable to design and execute a clinical trial to support marketing approval.

Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that believe their product candidates performed satisfactorily in preclinical studies and clinical trials have failed to obtain marketing approval of their products.

We may experience numerous unforeseen events during, or as a result of, clinical trials that could delay or prevent our ability to receive marketing approval or commercialize our product candidates, including:

•

clinical trials of our product candidates may produce negative or inconclusive results, and we may decide, or regulators may require us, to conduct additional clinical trials or abandon product development programs;

•

the number of patients required for clinical trials of our product candidates may be larger than we anticipate, enrollment in these clinical trials may be slower than we anticipate or participants may drop out of these clinical trials at a higher rate than we anticipate;

TABLE OF CONTENTS

•

we may be unable to enroll a sufficient number of patients in our clinical trials to ensure adequate statistical power to detect any statistically significant treatment effects;

•

our third-party contractors may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all;

•

regulators, institutional review boards or independent ethics committees may not authorize us or our investigators to commence a clinical trial or conduct a clinical trial at a prospective trial site;

•

we may have delays in reaching or fail to reach agreement on acceptable clinical trial contracts or clinical trial protocols with prospective trial sites;

•

we may have to suspend or terminate clinical trials of our product candidates for various reasons, including a finding that the participants are being exposed to unacceptable health risks;

•

regulators, institutional review boards or independent ethics committees may require that we or our investigators suspend or terminate clinical research for various reasons, including noncompliance with regulatory requirements or a finding that the participants are being exposed to unacceptable health risks;

•

clinical trials are costly and the cost of clinical trials of our product candidates may be greater than we anticipate;

•

the supply or quality of our product candidates or other materials necessary to conduct clinical trials of our product candidates may be insufficient or inadequate; and

•

our product candidates may have undesirable side effects or other unexpected characteristics, causing us or our investigators, regulators, institutional review boards or independent ethics committees to suspend or terminate the clinical trials.

Our product development costs will increase if we experience delays in testing or marketing approvals. We do not know whether any preclinical tests or clinical trials will begin as planned, will need to be restructured or will be completed on schedule, or at all. Significant preclinical or clinical trial delays also could shorten any periods during which we may have the exclusive right to commercialize our product candidates or allow our competitors to bring products to market before we do and impair our ability to successfully commercialize our product candidates and may harm our business and results of operations.

If we experience delays or difficulties in the enrollment of patients in our clinical trials, our receipt of necessary marketing approvals could be delayed or prevented.

We may not be able to initiate or continue clinical trials for our product candidates, including our planned clinical trials of ibezapolstat, if we are unable to locate and enroll a sufficient number of eligible patients to participate in these clinical trials. CDI is an acute infection that requires rapid diagnosis. For our clinical trials of ibezapolstat, we need to identify potential patients, test them for CDI and enroll them in the clinical trial within a 24-hour period. In addition, our competitors have ongoing clinical trials for product candidates that could be competitive with our product candidates, and patients who would otherwise be eligible for our clinical trials may instead enroll in clinical trials of our competitors’ product candidates. For our clinical trials of ibezapolstat, we need to identify potential patients and enroll them in the clinical trial based on a history of diarrhea within 24 hours of a positive stool test for C. difficile toxin.

Enrollment delays in our clinical trials may result in increased development costs for our product candidates, which would cause the value of our common stock to decline and limit our ability to obtain additional financing. Our inability to enroll a sufficient number of patients in our planned clinical trials of ibezapolstat would result in significant delays or may require us to abandon one or more clinical trials altogether.

Our failure to obtain costly government approvals, including required FDA approvals, or to comply with ongoing governmental regulations relating to our proposed products and formulations could delay or limit introduction of our proposed formulations and products and result in failure to achieve revenues or maintain our ongoing business.

Our research and development activities and the manufacture and marketing of our product candidates are subject to extensive regulation for safety, efficacy and quality by numerous government authorities in the

TABLE OF CONTENTS

U.S. and abroad. Before receiving FDA or foreign regulatory clearance to market our proposed formulations and products, we will have to demonstrate that our products are safe and effective in the patient population and for the diseases that are to be treated. Clinical trials, manufacturing and marketing of drugs are subject to the rigorous testing and approval process of the FDA and equivalent foreign regulatory authorities. The Federal Food, Drug and Cosmetic Act and other federal, state and foreign statutes and regulations govern and influence the testing, manufacture, labeling, advertising, distribution and promotion of drugs and medical devices. As a result, regulatory approvals can take years to obtain and require the expenditure of substantial financial, managerial and other resources.

Moreover, we may not receive regulatory approval of any of our proposed products. We may be unable to obtain all required regulatory approvals, and our failure to do so would materially and adversely affect our business, results of operations and financial condition.

Our results of operations may be adversely affected by current and potential future healthcare legislative and regulatory actions.

Legislative and regulatory actions affecting government prescription drug procurement and reimbursement programs occur relatively frequently. In the U.S., the Patient Protection and Affordable Care Act (the “ACA”) was enacted in 2010 to expand healthcare coverage. Since then, numerous efforts have been made to repeal, amend or administratively limit the ACA in whole or in part. For example, the Tax Cuts and Jobs Act (“TCJA”), signed into law by President Trump in 2017, repealed the individual health insurance mandate, which is considered a key component of the ACA. In December 2018, a U.S. District Court Judge in the Northern District of Texas ruled that the individual mandate was a critical and inseverable feature of the ACA, and therefore, because it was repealed as part of the TCJA, the remaining provisions of the ACA were invalid and the law in its entirety was unconstitutional. In December 2019, the U.S. Court of Appeals for the Fifth Circuit upheld the District Court ruling that the individual mandate was unconstitutional but remanded the case back to the District Court to determine whether other reforms enacted as part of the ACA but not specifically related to the individual mandate or health insurance could be severed from the rest of the ACA so as not to be declared invalid as well. On March 2, 2020, the United States Supreme Court granted the petitions for writs of certiorari to review this case and allocated one hour for oral arguments, which occurred on November 10, 2020. A decision from the Supreme Court is expected to be issued in spring 2021. It is unclear how this litigation and other efforts to repeal and replace the ACA will impact the implementation of the ACA, the pharmaceutical industry more generally, and our business. Complying with any new legislation or reversing changes implemented under the ACA could be time-intensive and expensive, resulting in a material adverse effect on our business.

Efforts to control prescription drug prices could also have a material adverse effect on our business. For example, in 2018, President Trump and the Secretary of the U.S. Department of Health and Human Services (“HHS”) released the “American Patients First Blueprint” and have begun implementing certain portions. The initiative includes proposals to increase generic drug and biosimilar competition, enable the Medicare program to negotiate drug prices more directly and improve transparency regarding drug prices and ways to lower consumers’ out-of-pocket costs. The Trump administration also proposed to establish an “international pricing index” that would be used as a benchmark to determine the costs and potentially limit the reimbursement of drugs under Medicare Part B. Among other pharmaceutical manufacturer industry-related proposals, Congress has proposed bills to change the Medicare Part D benefit to impose an inflation-based rebate in Medicare Part D and to alter the benefit structure to increase manufacturer contributions in the catastrophic phase. The volume of drug pricing-related bills has dramatically increased under the current Congress, and the resulting impact on our business is uncertain and could be material.

In addition, many states have proposed or enacted legislation that seeks to indirectly or directly regulate pharmaceutical drug pricing, such as by requiring biopharmaceutical manufacturers to publicly report proprietary pricing information or to place a maximum price ceiling on pharmaceutical products purchased by state agencies. For example, in 2017, California’s governor signed a prescription drug price transparency state bill into law, requiring prescription drug manufacturers to provide advance notice and explanation for price increases of certain drugs that exceed a specified threshold. Both Congress and state legislatures are considering various bills that would reform drug purchasing and price negotiations, allow

TABLE OF CONTENTS

greater use of utilization management tools to limit Medicare Part D coverage, facilitate the import of lower-priced drugs from outside the U.S. and encourage the use of generic drugs. Such initiatives and legislation may cause added pricing pressures on our products.

Changes to the Medicaid program at the federal or state level could also have a material adverse effect on our business. Proposals that could impact coverage and reimbursement of our products, including giving states more flexibility to manage drugs covered under the Medicaid program and permitting the re-importation of prescription medications from Canada or other countries, could have a material adverse effect by limiting our products’ use and coverage. Furthermore, state Medicaid programs could request additional supplemental rebates on our products as a result of an increase in the federal base Medicaid rebate. To the extent that private insurers or managed care programs follow Medicaid coverage and payment developments, they could use the enactment of these increased rebates to exert pricing pressure on our products, and the adverse effects may be magnified by their adoption of lower payment schedules.

Other proposed regulatory actions affecting manufacturers could have a material adverse effect on our business. It is difficult to predict the impact, if any, of any such proposed legislative and regulatory actions or resulting state actions on the use and reimbursement of our products in the U.S., but our results of operations may be adversely affected.

Risks Related to Our Dependence on Third Parties

We do not have a sales or marketing infrastructure and have no experience in the sale or marketing of pharmaceutical products. To achieve commercial success for any approved product, we must either develop a sales and marketing organization or outsource these functions to third parties. If ibezapolstat receives marketing approval, we intend to commercialize it in the U.S. with our own focused, specialized sales force. We plan to evaluate the potential for utilizing additional collaboration, distribution and marketing arrangements with third parties to commercialize ibezapolstat in other jurisdictions where we retain commercialization rights. There are risks involved with establishing our own sales and marketing capabilities and entering into arrangements with third parties to perform these services. For example, recruiting and training a sales force is expensive and time-consuming and could delay any product launch. If the commercial launch of a product candidate for which we recruit a sales force and establish marketing capabilities is delayed or does not occur for any reason, we would have prematurely or unnecessarily incurred these commercialization expenses. This may be costly, and our investment would be lost if we cannot retain or reposition our sales and marketing personnel.

Factors that may inhibit our efforts to commercialize our products on our own include:

•

our inability to recruit, train and retain adequate numbers of effective sales and marketing personnel;

•

the inability of sales personnel to obtain access to or persuade adequate numbers of physicians to prescribe any future products;

•

the lack of complementary products to be offered by sales personnel, which may put us at a competitive disadvantage relative to competitors with more extensive product lines; and

•

unforeseen costs and expenses associated with creating an independent sales and marketing organization.

If we enter into arrangements with third parties to perform sales and marketing services, our product revenues or the profitability of these product revenues will likely be lower than if we were to market and sell any products that we develop ourselves. In addition, we may not be successful in entering into arrangements with third parties to sell and market our product candidates or may be unable to do so on terms that are acceptable to us. We likely will have little control over such third parties, and any of them may fail to devote the necessary resources and attention to sell and market our products effectively. If we do not establish sales and marketing capabilities successfully, either on our own or in collaboration with third parties, we will not be successful in commercializing our product candidates.

TABLE OF CONTENTS

We do not currently have the infrastructure or internal capability to manufacture supplies of our product candidates for use in development and commercialization. We rely, and expect to continue to rely, on third-party manufacturers for the production of our product candidates for preclinical studies and clinical trials under the guidance of members of our organization. We do not have long-term supply agreements. Furthermore, the raw materials for our product candidates are sourced, in some cases, from a single-source supplier although other sources are available. For example, drug substance and drug product are sourced from our principal supplier, Piramal Pharma Solutions, in Ennore, India and Ahmedabad, India, respectively. Chemical raw materials used for drug substance manufacture are sourced locally in India and are generally available. Accordingly, we do not anticipate difficulties sourcing drug substance for our clinical trials or, if FDA approved, for our marketing period, but we have not yet sourced a backup supplier because we currently have sufficient supply to complete our Phase 2b clinical trial. We are considering U.S. sources of drug substance for the commercial period if ibezapolstat is FDA approved and we anticipate several manufacturing options will be available. If we were to experience an unexpected loss of supply of any of our product candidates or any of our future product candidates for any reason, whether as a result of manufacturing, supply or storage issues or otherwise, we could experience delays, disruptions, suspensions or terminations of, or be required to restart or repeat, any pending or ongoing clinical trials. For example, the extent to which the COVID-19 pandemic impacts our ability to procure sufficient supplies for the development of our products and product candidates will depend on the severity and duration of the spread of the virus, and the actions undertaken to contain COVID-19 or treat its effects.

We expect to continue to rely on third-party manufacturers for the commercial supply of any of our product candidates for which we obtain marketing approval. We may be unable to maintain or establish required agreements with third-party manufacturers or to do so on acceptable terms. Even if we are able to establish agreements with third-party manufacturers, reliance on third-party manufacturers entails additional risks, including:

•

the failure of the third party to manufacture our product candidates according to our schedule, or at all, including if our third-party contractors give greater priority to the supply of other products over our product candidates or otherwise do not satisfactorily perform according to the terms of the agreements between us and them;

•

the reduction or termination of production or deliveries by suppliers, or the raising of prices or renegotiation of terms;

•

the termination or nonrenewal of arrangements or agreements by our third-party contractors at a time that is costly or inconvenient for us;

•

the breach by the third-party contractors of our agreements with them;

•

the failure of third-party contractors to comply with applicable regulatory requirements;

•

the failure of the third party to manufacture our product candidates according to our specifications;

•

the mislabeling of clinical supplies, potentially resulting in the wrong dose amounts being supplied or active drug or placebo not being properly identified;

•

clinical supplies not being delivered to clinical sites on time, leading to clinical trial interruptions, or of drug supplies not being distributed to commercial vendors in a timely manner, resulting in lost sales; and

•

the misappropriation of our proprietary information, including our trade secrets and know-how.

We do not have complete control over all aspects of the manufacturing process of, and are dependent on, our contract manufacturing partners for compliance with cGMP regulations for manufacturing both active drug substances and finished drug products. Third-party manufacturers may not be able to comply with

TABLE OF CONTENTS

cGMP regulations or similar regulatory requirements outside of the U.S. If our contract manufacturers cannot successfully manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA, EMA or others, they will not be able to secure and/or maintain marketing approval for their manufacturing facilities. In addition, we do not have control over the ability of our contract manufacturers to maintain adequate quality control, quality assurance and qualified personnel. If the FDA, EMA or a comparable foreign regulatory authority does not approve these facilities for the manufacture of our 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 marketing approval for or market our product candidates, if approved. Our failure, or the failure of our third-party manufacturers, to comply with applicable regulations could subject us and our third-party manufacturers to warning letters or other enforcement-related letters, holds on clinical trials or could result in further sanctions being imposed on us or our third-party manufacturers, including fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of product candidates or drugs, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect supplies of our product candidates or drugs and harm our business and results of operations. Our current and anticipated future dependence upon others for the manufacture of our product candidates or drugs may adversely affect our future profit margins and our ability to commercialize any product candidates that receive marketing approval on a timely and competitive basis.

We rely on third party clinical investigators, contract research organizations (“CROs”), clinical data management organizations and consultants to design, conduct, supervise and monitor preclinical studies and clinical trials of our product candidates. Because we rely on third parties and do not have the ability to conduct preclinical studies or clinical trials independently, we have less control over the timing, quality and other aspects of preclinical studies and clinical trials than we would if we conducted them on our own. These investigators, CROs and consultants are not our employees and we have limited control over the amount of time and resources that they dedicate to our programs. These third parties may have contractual relationships with other entities, some of which may be our competitors, which may draw time and resources from our programs. Further, these third parties may not be diligent, careful or timely in conducting our preclinical studies or clinical trials, resulting in the preclinical studies or clinical trials being delayed or unsuccessful.

If we cannot contract with acceptable third parties on commercially reasonable terms, or at all, or if these third parties do not carry out their contractual duties, satisfy legal and regulatory requirements for the conduct of preclinical studies or clinical trials or meet expected deadlines, our preclinical and clinical development programs could be delayed and otherwise adversely affected. In all events, we are responsible for ensuring that each of our preclinical studies and clinical trials is conducted in accordance with the general investigational plan and protocols for the trial. The FDA and other health authorities require preclinical studies to be conducted in accordance with GLP and clinical trials to be conducted in accordance with GCP, including conducting, 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 clinical trial participants are protected. If we or our CROs fail to comply with these requirements, the data generated in our clinical trials may be deemed unreliable or uninterpretable and the FDA may require us to perform additional preclinical studies or clinical trials. Our reliance on third parties that we do not control does not relieve us of these responsibilities and requirements. Any such event could adversely affect our business, financial condition, results of operations and prospects.

The continuing efforts of government and insurance companies, health maintenance organizations and other payers of healthcare costs to contain or reduce costs of healthcare may affect our future revenues and profitability, and the future revenues and profitability of our potential customers, suppliers and collaborative partners and the availability of capital. For example, in the U.S., given recent federal and state government initiatives directed at lowering the total cost of healthcare, the U.S. Congress and state legislatures will likely continue to focus on healthcare reform, the cost of prescription pharmaceuticals and on the reform of the Medicare and Medicaid systems. While we cannot predict whether any such legislative or

TABLE OF CONTENTS

regulatory proposals will be adopted, the announcement or adoption of such proposals and related laws, rules and regulations could materially harm our business, financial condition, results of operations or stock price. Moreover, the passage of the ACA in 2010, and efforts to amend or repeal such law, has created significant uncertainty relating to the scope of government regulation of healthcare and related legal and regulatory requirements, which could have an adverse impact on sales of our products.

Moreover, our ability to commercialize our product candidates will depend in part on the extent to which appropriate reimbursement levels for the cost of such products and related treatments are obtained by governmental authorities, private health insurers and other organizations, such as HMOs. Consumers and third-party payers are increasingly challenging the prices charged for medical drugs and services. Also, the trend toward managed healthcare in the U.S. and the concurrent growth of organizations such as HMOs, which could control or significantly influence the purchase of healthcare services and drugs, as well as legislative proposals to reform healthcare or reduce government insurance programs, may all result in lower prices for or rejection of our proposed products.

Our relationships with customers and third-party payors will be subject to applicable anti-kickback, fraud and abuse and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and future earnings.

Healthcare providers, physicians and third-party payors will play a primary role in the recommendation and prescription of any product candidates for which we obtain marketing approval. Our future arrangements with third-party payors and customers may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations that may constrain the business or financial arrangements and relationships through which we would market, sell and distribute our products. As a pharmaceutical company, even though we do not and may not control referrals of healthcare services or bill directly to Medicare, Medicaid or other third-party payors, federal and state healthcare laws and regulations pertaining to fraud and abuse and patients’ rights are and will be applicable to our business. These regulations include:

•

the Federal Healthcare Anti-Kickback Statute that prohibits, among other things, persons from knowingly and willfully soliciting, offering, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward, or in return for, either the referral of an individual for, or the purchase, order or recommendation of, any good or service, for which payment may be made under a federal healthcare program such as Medicare and Medicaid, and which will constrain our marketing practices and the marketing practices of our licensees, educational programs, pricing policies, and relationships with healthcare providers or other entities;

•

the federal physician self-referral prohibition, commonly known as the Stark Law, which prohibits physicians from referring Medicare or Medicaid patients to providers of “designated health services” with whom the physician or a member of the physician’s immediate family has an ownership interest or compensation arrangement, unless a statutory or regulatory exception applies;

•

federal false claims laws that prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid, or other government reimbursement programs that are false or fraudulent, and which may expose entities that provide coding and billing advice to customers to potential criminal and civil penalties, including through civil whistleblower or qui tam actions, and including as a result of claims presented in violation of the Federal Healthcare Anti-Kickback Statute, the Stark Law or other healthcare-related laws, including laws enforced by the FDA;

•

the federal Health Insurance Portability and Accountability Act of 1996, (“HIPAA”), which imposes criminal and civil liability for executing a scheme to defraud any healthcare benefit program and also created federal criminal laws that prohibit knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false statements in connection with the delivery of or payment for healthcare benefits, items or services that, as amended by the Health Information Technology for Economic and Clinical Health Act, also imposes obligations, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of individually identifiable health information;

TABLE OF CONTENTS

•

federal physician sunshine requirements under the ACA, which requires manufacturers of approved drugs, devices, biologics and medical supplies to report annually to the HHS, information related to payments and other transfers of value to physicians, other healthcare providers, and teaching hospitals, and ownership and investment interests held by physicians and other healthcare providers and their immediate family members and applicable group purchasing organizations;

•

the Federal Food, Drug, and Cosmetic Act, which, among other things, strictly regulates drug product marketing, prohibits manufacturers from marketing drug products for off-label use and regulates the distribution of drug samples; and

•

state and foreign law equivalents of each of the above federal laws, such as anti-kickback and false claims laws, which may apply to sales or marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private insurers, state laws requiring pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government and which may require drug manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers or marketing expenditures, and state and foreign laws governing the privacy and security of health information in specified circumstances, many of which differ from each other in significant ways and often are not preempted by federal laws such as HIPAA, thus complicating compliance efforts.

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will involve substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, imprisonment, exclusion from government funded healthcare programs, such as Medicare and Medicaid, and the curtailment or restructuring of our operations. If any physicians or other healthcare providers or entities with whom we expect to do business are found to not be in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs.

Risks Related to Intellectual Property

We may be involved in lawsuits to protect or enforce our patents.

Competitors may infringe our patents. To counter infringement or unauthorized use, we or our collaborators may be required to file infringement lawsuits that can be expensive and time-consuming. In addition, in an infringement proceeding, a court may decide that one of our patents is not valid, is unenforceable and/or is not infringed, or may refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technology in question. An adverse result in any litigation or defense proceedings could put one or more of our patents at risk of being invalidated or interpreted narrowly and could put any pending applications at risk of being interpreted narrowly and not issuing.

Interference proceedings or derivation proceedings may be filed to determine the priority of inventions with respect to our patents or patent applications or those of our licensors (if any). An unfavorable outcome could require us to cease using the related technology or to attempt to license rights from the prevailing party. Our business could be harmed if the prevailing party does not offer us a license on commercially reasonable terms. We may not be able to prevent, alone or with our licensors (if any), misappropriation of our intellectual property rights, both in the U.S. and in countries where the laws may not protect those rights as fully as in the U.S. Other proceedings, such as proceedings before the U.S. Patent and Trademark Office Patent Trial and Appeal Board, filed by a third party may result in the invalidation of one or more of our 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. There could also be public announcements of the results of hearings,

TABLE OF CONTENTS

motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a material adverse effect on the price of our common stock.

Intellectual property litigation could cause us to spend substantial resources and distract our personnel from their normal responsibilities.

Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims, regardless of their merit, would cause us to incur significant expenses, and could distract our technical and management personnel from their normal responsibilities. In the event of a successful claim of infringement against us, we may have to pay substantial damages, including treble damages and attorneys’ fees for willful infringement, in addition to paying royalties, redesign infringing products or obtain one or more licenses from third parties, which may be impossible or require substantial time and monetary expenditure. A court may also issue an injunction against us preventing us from manufacturing and bringing our products to market. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our common stock. Such litigation or proceedings could substantially increase our operating losses and reduce the resources available for development activities or any future sales, marketing or distribution activities. We may not have sufficient financial or other resources to conduct such litigation or proceedings adequately. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could compromise our ability to compete in the marketplace.

We may need to license certain intellectual property from third parties, and such licenses may not be available or may not be available on commercially reasonable terms.

A third party may hold intellectual property, including patent rights, that is important or necessary to the development or commercialization of our products. It may be necessary for us to use the patented or proprietary technology of third parties to commercialize our products, in which case we would be required to obtain a license from these third parties on commercially reasonable terms, or our business could be harmed, possibly materially. Such licenses may not be available which could prevent us from commercializing our products. Further, if we are alleged to infringe third party intellectual property rights, we could face costly litigation, the outcome of which could negatively affect or prevent us from commercializing or developing our products. In the event of an adverse decision against us in a litigation, we could be required to: pay substantial damages and license fees, or even be prevented from using or commercializing our technologies and methods; and also be prevented from further research and development efforts. In such case, we may be unable to develop alternative non-infringing products or methods and unable to obtain one or more licenses from third parties.

Our ability to license, obtain, enforce and maintain patents, maintain trade secret protection and operate without infringing the proprietary rights of others is important to the commercialization of any formulations or products under development. The patent positions of biotechnology and pharmaceutical companies, including ours, are frequently uncertain and involve complex legal and factual questions. In addition, the coverage claimed in a patent application can be significantly reduced before the patent is issued. Consequently, our patents, patent applications and other intellectual property rights may not provide protection against competitive technologies or products or may be held invalid if challenged or could be circumvented. Our competitors may also independently develop products similar to ours or design around or otherwise circumvent patents issued to, or licensed by, us. In addition, the laws of some foreign countries may not protect our proprietary rights to the same extent as U.S. law. Any of these occurrences would have a material adverse effect on our business.

Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to incur significant expenses, and could distract our technical and management

TABLE OF CONTENTS

personnel from their normal responsibilities. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments. Such litigation or proceedings could substantially increase our operating losses and reduce the resources available for development, sales, marketing or distribution activities. We may not have sufficient financial or other resources to adequately conduct such litigation or proceedings. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial resources. Accordingly, costs and lost management time, as well as uncertainties resulting from the initiation and continuation of patent litigation or other proceedings, could have a material adverse effect on our ability to compete in the marketplace.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.

In addition to seeking patents for some of our technology and products, we will also rely on trade secrets, including unpatented know-how, technology and other proprietary and confidential information, to maintain our competitive position. We will seek to protect these trade secrets, in part, by entering into non-disclosure and confidentiality agreements with parties who have access to them, such as our employees, corporate collaborators, outside scientific collaborators, contract manufacturers, consultants, advisors and other third parties. However, we cannot guarantee that we will have executed these agreements with each party that may have or have had access to our trade secrets or that the agreements we do execute will provide adequate protection. Any party with whom we have executed such an agreement could breach that agreement and disclose our proprietary or confidential information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, some courts inside and outside the U.S. are less willing or unwilling to protect trade secrets. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent them, or those to whom they communicate it, from using that technology or information to compete with us. If any of our trade secrets, particularly unpatented know-how, were to be obtained or independently developed by a competitor, our competitive position would be harmed.

Risks Related to this Offering and Ownership of Our Common Stock

We expect our expenses to increase in connection with our ongoing activities, particularly as we continue research and development and initiate additional clinical trials of our product candidates and seek regulatory approval for these and potentially other product candidates. 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. In particular, the costs that may be required for the manufacture of any product candidate that receives marketing approval may be substantial. Accordingly, we may need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, reduce or eliminate our research and development programs or any future commercialization efforts.

We may be required to obtain further funding through public or private equity offerings, debt financings, collaborations or licensing arrangements or other sources. Adequate additional funding may not be available to us on acceptable terms or at all. Our failure to raise capital as and when needed would have a negative impact on our financial condition and our ability to pursue our business strategy.

Our future capital requirements will depend on many factors, including:

•

the timing, progress, and results of our ongoing and planned clinical trials of our product candidates;

•

our ability to manufacture sufficient clinical supply of our products candidates and the costs thereof;

•

discussions with regulatory agencies regarding the design and conduct of our clinical trials and the costs, timing and outcome of regulatory review of our product candidates;

TABLE OF CONTENTS

•

the cost and timing of future commercialization activities, including product manufacturing, marketing, sales and distribution, for any of our product candidates for which we receive marketing approval;

•

the costs of any other product candidates or technologies we pursue;

•

our ability to establish and maintain strategic partnerships, licensing or other arrangements and the financial terms of such agreements;

•

the revenue, if any, received from commercial sales of any product candidates for which we receive marketing approval; and

•

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

Identifying potential product candidates and conducting clinical trials is a time-consuming, expensive and uncertain process that takes years to complete, and we may never generate the necessary data or results required to obtain regulatory approval and achieve product sales. In addition, our product candidates, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of products that we do not expect to be commercially available for several years, if at all. Accordingly, we will need to continue to rely on additional financing to achieve our business objectives. Adequate additional financing may not be available to us on acceptable terms, or at all. In addition, we may seek additional capital due to favorable market conditions or strategic considerations, even if we believe we have sufficient funds for our current or future operating plans. We also have certain restrictions on issuing shares and incurring indebtedness that are part of our investor rights agreement.

Any additional fundraising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to develop and commercialize our product candidates. Our ability to raise additional funds will depend, in part, on the success of our preclinical studies and clinical trials and other product development activities, regulatory events, our ability to identify and enter into in-licensing or other strategic arrangements, and other events or conditions that may affect our value or prospects, as well as factors related to financial, economic and market conditions, many of which are beyond our control. We cannot be certain that sufficient funds will be available to us when required or on acceptable terms, if at all. Raising additional capital through the sale of securities could cause significant dilution to our stockholders. If we are unable to secure additional funds on a timely basis or on acceptable terms, we may be required to defer, reduce or eliminate significant planned expenditures, restructure, curtail or eliminate some or all of our development programs or other operations, dispose of technology or assets, pursue an acquisition of our company by a third party at a price that may result in a loss on investment for our stockholders, enter into arrangements that may require us to relinquish rights to certain of our product candidates, technologies or potential markets, file for bankruptcy or cease operations altogether. Any of these events could have a material adverse effect on our business, financial condition and results of operations. Moreover, if we are unable to obtain additional funds on a timely basis, there will be substantial doubt about our ability to continue as a going concern and increased risk of insolvency and loss of investment by our stockholders.

Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to 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 public or private equity offerings, debt financings and/or license and development agreements with collaboration partners. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interests of our stockholders may be materially diluted, and the terms of such securities could include liquidation or other preferences or other rights such as anti-dilution rights that adversely affect the rights of our stockholders. Debt financing and preferred equity financing, if available, may involve agreements that include restrictive covenants that limit our ability to take specified actions, such as incurring additional debt, making capital expenditures or declaring dividends.

If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and

TABLE OF CONTENTS

market ourselves. If we raise funds through collaborations, strategic partnerships 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 you purchase shares of our common stock in our initial public offering, you will experience substantial and immediate dilution.

The initial public offering price of $6.00 per share is substantially higher than the net tangible book value per share of our outstanding common stock immediately following the completion of this offering. If you purchase shares of common stock in this offering, you will experience substantial and immediate dilution in the pro forma net tangible book value per share of $4.45 per share as of March 31, 2021. That is because the price that you pay will be substantially greater than the pro forma net tangible book value per share of the common stock that you acquire. This dilution is due in large part to the fact that our earlier investors paid substantially less than the initial public offering price when they purchased their shares of our capital stock. You will experience additional dilution when those holding stock options or warrants exercise their right to purchase common stock under our equity incentive plans or when we otherwise issue additional shares of common stock. See “Dilution.”

Future sales of a substantial number of shares of our common stock may depress the price of our shares.

If any of our other stockholders sells or otherwise disposes of a large number of shares of our common stock, or if we issue a large number of shares of our common stock in connection with future acquisitions, financings, or other circumstances, the market price of shares of our common stock could decline significantly.

Subject to the lock-up agreements described below, all of the shares of our common stock sold in this offering will be freely tradable without restriction, except for shares of our common stock owned by any of our affiliates. Immediately after this offering, the public market for our common stock will include only the 2,500,000 shares of our common stock that are being sold in this offering, based upon the initial public offering price of $6.00 per share, or 2,875,000 shares of our common stock if the underwriters exercise their option to purchase additional shares of our common stock from us in full.

Our directors, officers and holders of substantially all of our capital stock and securities convertible into our capital stock have entered into lock-up agreements in which they have agreed that they will not sell, directly or indirectly, any shares of our common stock for a period of 180 days from the date of this prospectus (subject to certain exceptions) without the prior written consent of Alexander Capital L.P. See “Shares Eligible for Future Sale.”

Furthermore, assuming the Corporate Conversion, the accelerated vesting of currently unvested board of director and corporate advisory council membership interests and the completion of this offering had occurred on May 25, 2021, warrants exercisable for up to 1,437,560 shares of our common stock at a weighted average exercise price of $2.88 per share were outstanding. The exercise of any of these warrants would result in additional dilution, and the sale of up to 1,437,560 shares of our common stock (assuming no cashless exercise) issuable upon exercise of outstanding warrants could also lower the market price of our common stock.

Because we do not anticipate paying any cash dividends on our common stock in the foreseeable future, capital appreciation, if any, will be your sole source of gain.

We have never paid or declared any cash dividends on our common stock. We currently intend to retain earnings, if any, to finance the growth and development of our business and we do not anticipate paying any cash dividends in the foreseeable future. As a result, only appreciation of the price of our common stock will provide a return to our members.

Provisions in our corporate charter documents and under Delaware law could make an acquisition of our company, which may be beneficial to our stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current management.

These provisions might discourage, delay or prevent a change in control of our company or a change in our management. The existence of these provisions could adversely affect the voting power of holders of

TABLE OF CONTENTS

common stock and limit the price that investors might be willing to pay in the future for shares of our common stock. Furthermore, we have the authority to issue shares of our preferred stock without further stockholder approval, the rights of which will be determined at the discretion of the board of directors and that, if issued, could operate as a “poison pill” to dilute the stock ownership of a potential hostile acquirer to prevent an acquisition that our board of directors does not approve. In addition, our certificate of incorporation and bylaws contain provisions that may make the acquisition of our company more difficult, including the following:

•

our authorized but unissued and unreserved common stock and preferred stock could make more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise;

•

our board of directors is classified into three classes of directors with staggered three-year terms and directors are only able to be removed from office for cause;

•

our stockholders will only be able to take action at a meeting of stockholders and will not be able to take action by written consent for any matter, except in certain circumstances;

•

a special meeting of our stockholders may only be called by the chairperson of our board of directors or a majority of our board of directors;

•

advance notice procedures apply for stockholders to nominate candidates for election as directors or to bring matters before an annual meeting of stockholders; and

•

certain amendments to our certificate of incorporation and any amendments to our bylaws by our stockholders will require the approval of at least two-thirds of our then-outstanding voting power entitled to vote generally in an election of directors, voting together as a single class.

We are an “emerging growth company,” and a “smaller reporting company” and we cannot be certain if the reduced reporting requirements applicable to emerging growth companies and smaller reporting companies will make our common stock less attractive to investors.

We are an “emerging growth company,” as defined in the JOBS Act. For as long as we continue to be an emerging growth company, we intend to take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including:

•

being permitted to provide only two years of audited financial statements, in addition to any required unaudited interim financial statements, with correspondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure in this prospectus;

•

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

•

not being required to 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;

•

reduced disclosure obligations regarding executive compensation in this prospectus and our periodic reports and proxy statements; and

•

exemptions from the requirements of holding nonbinding advisory stockholder votes on executive compensation and stockholder approval of any golden parachute payments not previously approved.

We cannot predict if investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.

We will remain an emerging growth company until the earlier of (1) the last day of the fiscal year (a) following the fifth anniversary of the completion of this offering, (b) in which we have total annual gross revenue of at least $1.07 billion (as adjusted for inflation pursuant to SEC rules from time to time), or (c) in which we are deemed to be a large accelerated filer, which means the market value of our common

TABLE OF CONTENTS

stock that is held by non-affiliates exceeds $700 million as of the prior June 30th, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.

Under the JOBS Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as those standards apply to private companies. We intend to take advantage of the extended transition period for adopting new or revised accounting standards under the JOBS Act as an emerging growth company. As a result of this election, our financial statements may not be comparable to companies that comply with public company effective dates.

We are also a smaller reporting company, and we will remain a smaller reporting company until the fiscal year following the determination that our voting and non-voting common shares held by non-affiliates is more than $250 million measured on the last business day of our second fiscal quarter, or our annual revenues are less than $100 million during the most recently completed fiscal year and our voting and non-voting common shares held by non-affiliates is more than $700 million measured on the last business day of our second fiscal quarter.

Similar to emerging growth companies, smaller reporting companies have reduced disclosure obligations, such as an exemption from providing selected financial data and an ability to provide simplified executive compensation information and only two years of audited financial statements.

The price of our common stock may be volatile and fluctuate substantially, which could result in substantial losses for our stockholders.

The initial public offering price for our common stock will be determined through negotiations between the underwriters and us and may vary from the market price of our common stock following the completion of this offering. Our stock price may be volatile. The stock market in general, and the market for pharmaceutical companies in particular, has experienced extreme volatility that has often been unrelated to the operating performance of particular companies. As a result of this volatility, investors may not be able to sell their shares of common stock at or above the price they paid for their shares. The market price for our common stock may be influenced by many factors, including:

•

actual or anticipated results from and any delays in our clinical trials, as well as results of regulatory input on our clinical trial programs and regulatory reviews relating to the approval of our product candidates;

•

the results of our efforts to discover, develop, acquire or in-license additional product candidates or products;

•

failure or discontinuation of any of our clinical development programs;

•

the level of expenses related to any of our product candidates or clinical development programs;

•

commencement or termination of any collaboration or licensing arrangement;

•

disputes or other developments relating to proprietary rights, including patents, litigation matters and our ability to obtain patent protection for our technologies;

•

announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures and capital commitments;

•

additions or departures of key scientific or management personnel;

•

variations in our financial results or those of companies that are perceived to be similar to us;

•

new products, product candidates or new uses for existing products introduced or announced by our competitors, and the timing of these introductions or announcements;

•

results of clinical trials of product candidates of our competitors;

•

general economic and market conditions and other factors that may be unrelated to our operating performance or the operating performance of our competitors, including changes in market valuations of similar companies;

•

regulatory or legal developments in the U.S. and other countries;

TABLE OF CONTENTS

•

changes in the structure of healthcare payment systems;

•

conditions or trends in the pharmaceutical, biotechnology and medical device industries;

•

actual or anticipated changes in earnings estimates, development timelines or recommendations by securities analysts;

•

announcement or expectation of additional financing efforts;

•

sales of common stock by us or our stockholders in the future, as well as the overall trading volume of our common stock; and

•

the other factors described in this “Risk Factors” section.

If our quarterly operating results fall below the expectations of investors or securities analysts, the price of our common stock could decline substantially. Furthermore, any quarterly fluctuations in our operating results may, in turn, cause the price of our stock to fluctuate substantially. We believe that quarterly comparisons of our financial results are not necessarily meaningful and should not be relied upon as an indication of our future performance.

In the past, following periods of volatility in the market price of a company’s securities, securities class-action litigation often has been instituted against that company. Such litigation, if instituted against us, could cause us to incur substantial costs to defend such claims and divert management’s attention and resources, which could seriously harm our business, financial condition, results of operations and prospects.

Our largest stockholders will exercise significant influence over our company for the foreseeable future, including the outcome of matters requiring stockholder approval.

As of May 25, 2021, our officers, directors and their affiliates collectively own 2,368,304 shares of our common stock (on an as-converted basis) or approximately 34.5% of our outstanding shares of common stock (on an as-converted basis). After the consummation of the offering contemplated hereby, based upon the initial public offering price of $6.00 per share and assuming no exercise by the underwriters of their option to purchase additional shares of our common stock in this offering, our officers, directors and their affiliates will collectively own 2,368,304 shares of our common stock (on an as-converted basis) or approximately 25.5% of our outstanding shares of common stock (on an as-converted basis). Accordingly, if these stockholders were to choose to act together, they could have a significant influence over all matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions, such as a merger or other sale of our company or all or a significant percentage of our assets. This concentration of ownership could limit your ability to influence corporate matters and may have the effect of delaying or preventing a third party from acquiring control over us.

We cannot assure you that the interests of our officers, directors and affiliated persons will coincide with the interests of the investors. So long as our officers, directors and affiliated persons collectively controls a significant portion of our common stock, these individuals and/or entities controlled by them, will continue to collectively be able to strongly influence or effectively control our decisions. Therefore, you should not invest in reliance on your ability to have any control over our company. See “Principal Stockholders,” “Certain Relationships and Related Party Transactions” and “Description of Capital Stock.”

Our common stock has no prior public market, and we cannot assure you that an active trading market will develop.

Prior to this offering, there has not been a public market for our common stock. Although we have been approved to list our common stock on The Nasdaq Capital Market (the “Nasdaq”), an active trading market in our common stock might not develop or continue. The initial public offering price for our common stock will be determined through negotiations between the underwriters and us and may vary from the market price of our common stock following the completion of this offering. If you purchase shares of our common stock in this offering, you will pay a price that was not established in a competitive market. Rather, you will pay a price that was determined through negotiations with the underwriters based upon an assessment of the valuation of our common stock and a book-building process. The public market may not agree with or accept this valuation, in which case you may not be able to sell your shares of our common

TABLE OF CONTENTS

stock at or above the initial offering price. In addition, if an active trading market does not develop, you may have difficulty selling your shares of our common stock at an attractive price, or at all. An inactive market may also impair our ability to raise capital by selling shares of our common stock and may impair our ability to acquire other companies, products or technologies by using shares of our common stock as consideration.

Nasdaq may delist our securities from trading on its exchange, which could limit investors’ ability to make transactions in our securities and subject us to additional trading restrictions.

Should we fail to satisfy the Nasdaq’s continued listing requirements, such as the corporate governance requirements or the minimum closing bid price requirement, Nasdaq may take steps to delist our common stock. Such a delisting would likely have a negative effect on the price of our common stock, and would impair your ability to sell or purchase our common stock when you wish to do so. In the event of a delisting, we would take actions to restore our compliance with Nasdaq’s listing requirements, but we can provide no assurance that any such action taken by us would allow our common stock to become listed again, stabilize the market price or improve the liquidity of our common stock, prevent our common stock from dropping below Nasdaq’s minimum bid price requirement or prevent future non-compliance with the Nasdaq’s listing requirements.

If Nasdaq does not maintain the listing of our securities for trading on its exchange, we could face significant material adverse consequences, including:

•

a limited availability of market quotations for our common stock;

•

reduced liquidity for our common stock;

•

a determination that our common stock is a “penny stock” which will require brokers trading in our common stock to adhere to more stringent rules and possibly result in a reduced level of trading activity in the secondary trading market for our securities;

•

a limited amount of news and analyst coverage; and

•

a decreased ability to issue additional common stock or obtain additional financing in the future.

General Risk Factors

Cyber incidents or attacks directed at us could result in information theft, data corruption, operational disruption and/or financial loss.

We depend on digital technologies, including information systems, infrastructure and cloud applications and services, including those of third parties with which we may deal. Sophisticated and deliberate attacks on, or security breaches in, our systems or infrastructure, or the systems or infrastructure of third parties or the cloud, could lead to corruption or misappropriation of our assets, proprietary information and sensitive or confidential data. As an early-stage company without significant investments in data security protection, we may not be sufficiently protected against such occurrences. We may not have sufficient resources to adequately protect against, or to investigate and remediate any vulnerability to, cyber incidents. It is possible that any of these occurrences, or a combination of them, could have adverse consequences on our business and lead to financial loss.

Our employees, principal investigators, consultants and commercial partners may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements and insider trading.

We are exposed to the risk of fraud or other misconduct by our employees, principal investigators, consultants and collaborators. Misconduct by these parties could include intentional failures to comply with the regulations of the FDA and non-U.S. regulators, to provide accurate information to the FDA and non-U.S. regulators, to comply with healthcare fraud and abuse laws and regulations in the U.S. and abroad, to report financial information or data accurately or to disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices.

TABLE OF CONTENTS

These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Such misconduct could also involve the improper use of information obtained during clinical studies that could result in regulatory sanctions and cause serious harm to our reputation. It is not always possible to identify and deter employee misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. If any such actions are instituted against us and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant fines or other sanctions.

There may be limitations on the effectiveness of our internal controls, and a failure of our control systems to prevent error or fraud may materially harm us.

Proper systems of internal control over financial accounting and disclosure are critical to the operation of a public company. We may be unable to effectively establish such systems, especially in light of the fact that we expect to operate as a publicly reporting company. This would leave us without the ability to reliably assimilate and compile financial information about us and significantly impair our ability to prevent error and detect fraud, all of which would have a negative impact on us from many perspectives.

Moreover, we do not expect that disclosure controls or internal control over financial reporting, even if established, will prevent all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. Failure of our control systems to prevent error or fraud could materially adversely impact us.

The estimates and judgments we make, or the assumptions on which we rely, in preparing our financial statements could prove inaccurate.

Our financial statements have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of our assets, liabilities, revenues and expenses, the amounts of charges accrued by us and related disclosure of contingent assets and liabilities. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. We cannot assure, however, that our estimates, or the assumptions underlying them, will not change over time or otherwise prove inaccurate. Any potential litigation related to the estimates and judgments we make, or the assumptions on which we rely, in preparing our financial statements could have a material adverse effect on our financial results, harm our business, and cause our share price to decline.

Failure to comply with the United States Foreign Corrupt Practices Act could subject us to penalties and other adverse consequences.

As a Delaware corporation, we are subject to the United States Foreign Corrupt Practices Act, which generally prohibits U.S. companies from engaging in bribery or other prohibited payments to foreign officials for the purpose of obtaining or retaining business. Some foreign companies, including some that may compete with us, may not be subject to these prohibitions. Corruption, extortion, bribery, pay-offs, theft and other fraudulent practices may occur from time-to-time in countries in which we conduct our business. However, our employees or other agents may engage in conduct for which we might be held responsible. If our employees or other agents are found to have engaged in such practices, we could suffer severe penalties and other consequences that may have a material adverse effect on our business, financial condition and results of operations.

Litigation may adversely affect our business, financial condition and results of operations.

From time to time in the normal course of our business operations, we may become subject to litigation that may result in liability material to our financial statements as a whole or may negatively affect our

TABLE OF CONTENTS

operating results if changes to our business operation are required. The cost to defend such litigation may be significant and may require a diversion of our resources. There also may be adverse publicity associated with litigation that could negatively affect customer perception of our business, regardless of whether the allegations are valid or whether we are ultimately found liable. As a result, litigation may adversely affect our business, financial condition and results of operations.

If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could harm our business.

We are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes. From time to time and in the future, our operations may involve the use of hazardous and flammable materials, including chemicals and biological materials, and may also produce hazardous waste products. Even if we contract with third parties for the disposal of these materials and waste products, we cannot completely eliminate the risk of contamination or injury resulting from these materials. In the event of contamination or injury resulting from the use or disposal of our hazardous materials, we could be held liable for any resulting damages, and any liability could exceed our resources. We also could incur significant costs associated with civil or criminal fines and penalties for failure to comply with such laws and regulations.

We maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting from the use of hazardous materials, but this insurance may not provide adequate coverage against potential liabilities. However, we do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us.

In addition, we may incur substantial costs to comply with current or future environmental, health and safety laws and regulations. Current or future environmental laws and regulations may impair our research, development or production efforts that could adversely affect our business, financial condition, results of operations or prospects. In addition, failure to comply with these laws and regulations may result in substantial fines, penalties or other sanctions.

We have broad discretion in how we use our cash, cash equivalents and marketable securities and may not use these financial resources effectively, which could affect our results of operations and cause our stock price to decline.

Our management has considerable discretion in the investment of our cash and any cash equivalents and marketable securities. We intend to use the proceeds of this offering for general corporate purposes, which may include, without limitation, expenditures relating to research, development and clinical trials relating to our products and product candidates, manufacturing, capital expenditures, hiring additional personnel, acquisitions of new technologies or products, the payment, repayment, refinancing, redemption or repurchase of existing or future indebtedness, obligations or capital stock, and working capital. We may use the cash, cash equivalents and marketable securities for purposes that do not yield a significant return or any return at all for our stockholders. In addition, pending their use, we may invest the financial resources from our securities offerings in a manner that does not produce income or that loses value.

If securities or industry analysts do not publish research or reports about our business, or they publish negative reports about our business, our share price 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, our market and our competitors. We do not have any control over these analysts. If one or more of the analysts who cover us downgrade our shares or change their opinion of our shares, our share price would likely decline. If one or more of these analysts cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our share price or trading volume to decline.

Delaware law contains anti-takeover provisions that could deter takeover attempts that could be beneficial to our stockholders.

Provisions of Delaware law could make it more difficult for a third party to acquire us, even if doing so would be beneficial to our stockholders. Section 203 of the Delaware General Corporation Law may make

TABLE OF CONTENTS

the acquisition of our company and the removal of incumbent officers and directors more difficult by prohibiting stockholders holding 15% or more of our outstanding voting stock from acquiring us, without the consent of our board of directors, for at least three years from the date they first hold 15% or more of the voting stock.

Our certificate of incorporation and our bylaws provide that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.

Our certificate of incorporation and our bylaws provide that the Court of Chancery of the State of Delaware is the exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claim against us arising pursuant to the Delaware General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that is governed by the internal affairs doctrine. Notwithstanding the foregoing, the exclusive forum provision does not apply to suits brought to enforce any liability or duty created by the Exchange Act, the Securities Act or any other claim for which the federal courts have exclusive jurisdiction. Unless we consent in writing to the selection of an alternative forum, the federal district courts of the U.S. of America shall, to the fullest extent permitted by applicable law, be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. The choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers and other employees. Alternatively, if a court were to find the choice of forum provision contained in our certificate of incorporation and our bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could materially and adversely affect our business, financial condition, and results of operation.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus contains forward-looking statements. You can generally identify forward-looking statements by our use of forward-looking terminology such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “potential,” “predict,” “seek,” “will” or “should,” or the negative thereof or other variations thereon or comparable terminology.

•

the costs of being a public company;

•

our ability to keep pace with technological advances;

•

the success of our marketing activities;

•

a disruption of breach of our information technology systems;

•

our dependence on third parties;

•

TABLE OF CONTENTS

USE OF PROCEEDS

We estimate that the net proceeds from the sale of shares of common stock in this offering will be approximately $12.7 million, based on an initial public offering price of $6.00 per share, and after deducting the underwriting discounts and commissions and estimated offering expenses payable by us and assuming no exercise of the underwriter’s over-allotment option. If the underwriters exercise their over-allotment option in full, we estimate that our net proceeds will be $14.8 million based on an initial public offering price of $6.00 per share, and after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

We intend to use the net proceeds from this offering (i) to complete the Phase 2b clinical trial of ibezapolstat in patients with CDI (approximately $4 million), (ii) to complete pre-clinical development of ACX-375C (approximately $6 million) and (iii) for general corporate purposes, which may include, without limitation, expenditures relating to research, development and clinical trials other than those specified above, manufacturing, capital expenditures, hiring additional personnel, acquisitions of new technologies or products, the payment, repayment, refinancing, redemption or repurchase of existing or future indebtedness, obligations or capital stock, and working capital. Accordingly, using the proceeds raised in this offering, we expect ibezapolstat to complete Phase 2b testing and we expect ACX-375C to be IND ready, or ready for testing in clinical trials.

This expected use of the net proceeds from this offering represents our intentions based upon our current plans and business conditions, which could change in the future as our plans and business conditions evolve. We may also use a portion of the net proceeds to in-license, acquire or invest in additional businesses, technologies, products or assets, although currently we have no specific agreements, commitments or understandings in this regard. As of the date of this prospectus, we cannot predict with certainty all of the particular uses for the net proceeds to be received upon the closing of this offering or the amounts that we will actually spend on the uses set forth above. Predicting the cost necessary to develop product candidates can be difficult and we anticipate that we will need additional funds to complete the development of any product candidates we identify. The amounts and timing of our actual expenditures and the extent of clinical development may vary significantly depending on numerous factors, including the progress of our development efforts, the status of and results from pre-clinical studies and any ongoing clinical trials or clinical trials we may commence in the future, as well as any collaborations that we may enter into with third parties for our product candidates and any unforeseen cash needs. As a result, our management will retain broad discretion over the allocation of the net proceeds from this offering.

We believe that the net proceeds from this offering, together with our existing cash and cash equivalents, will enable us to fund our operating expenses and capital expenditure requirements through the end of 2023. We have based this estimate on assumptions that may prove to be incorrect, and we could use our available capital resources sooner than we currently expect. We may satisfy our future cash needs through the sale of equity securities, debt financings, working capital lines of credit, corporate collaborations or license agreements, grant funding, interest income earned on invested cash balances or a combination of one or more of these sources. We will also continue to pursue non-dilutive grants for late stage clinical trials.

Pending our use of the net proceeds from this offering, we intend to invest the net proceeds in a variety of capital preservation investments, including cash and cash equivalents, short-term investment-grade interest-bearing instruments and U.S. government securities.

DIVIDEND POLICY

We have never declared or paid any cash dividends on our capital stock. We intend to retain future earnings, if any, to finance the operation and expansion of our business and do not anticipate paying any cash dividends in the foreseeable future. Any future determination related to our dividend policy will be made at the discretion of our board of directors after considering our financial condition, results of operations, capital requirements, business prospects and other factors the board of directors deems relevant, and subject to the restrictions contained in any future financing instruments.

TABLE OF CONTENTS

DILUTION

If you invest in our common stock in this offering, your ownership interest will be immediately diluted to the extent of the difference between the initial public offering price per share of our common stock and the pro forma as adjusted net tangible book value per share of our common stock after this offering. Pro forma net tangible book value per share represents the book value of our tangible assets less the book value of our total liabilities divided by the number of shares of common stock then issued and outstanding after giving effect to the Corporate Conversion and the accelerated vesting of currently unvested membership interests.

The historical net tangible book value as of March 31, 2021 was $2.5 million or $0.18 per Class A membership interests and Class B membership interests. Historical net tangible book value per membership interest represents the amounts of our tangible assets less total liabilities, divided by the total number of Class A and Class B membership interests outstanding. On a pro forma basis, after giving effect to the Corporate Conversion, and the accelerated vesting of currently unvested membership interests, our pro forma net tangible book value as of March 31, 2021 was $2.5 million, or $0.35 per share, based on 7,041,159 shares of our common stock outstanding after the Corporate Conversion.

After giving effect to our sale of 2,500,000 shares of common stock in this offering at an initial public offering price of $6.00 per share, after giving effect to the Corporate Conversion and the accelerated vesting of currently unvested membership interests, after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us, and assuming no exercise of the underwriter’s over-allotment option and no exercise of outstanding options or warrants, our pro forma as adjusted net tangible book value as of March 31, 2021 would have been approximately $14.8 million, or approximately $1.55 per share. This amount represents an immediate and substantial dilution of $4.45 per share to new investors purchasing common stock in this offering. The following table illustrates this dilution:

Assumed initial public offering price per share			$	6.00
Historical net tangible book value per Class A membership interest and Class B membership interest as of March 31, 2021	$	0.18
Pro forma net tangible book value per share as of March 31, 2021 before this offering and after giving effect to the Corporate Conversion and the accelerated vesting of currently unvested membership interests(1)		0.35
Increase in the pro forma net tangible book value per share after giving effect to this offering		0.17
Pro forma as adjusted net tangible book value per share after this offering				1.55
Dilution per share to new investors participating in this offering			$	4.45

(1)

Excludes the Class B membership interests granted in January 2021 and subsequently cancelled in March 2021.

If the underwriters exercise their option to purchase additional shares of our common stock in full, the pro forma as adjusted net tangible book value after this offering would be $1.70 per share, and the dilution to new investors would be $4.30 per share, and after deducting underwriting discounts and commissions and the estimated offering expenses payable by us.

The following table summarizes on the pro forma as adjusted basis described above, as of March 31, 2021, the difference between the number of shares of common stock purchased from us, the total consideration paid or to be paid and the average price per share paid or to be paid by existing stockholders and new investors in this offering at an initial public offering price of $6.00 per share, before deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us, and assuming no exercise of the underwriter’s over-allotment option. As the table shows, new investors purchasing common stock in this offering will pay an average price per share substantially higher than our existing stockholders paid.

TABLE OF CONTENTS

	Shares Purchased				Total Consideration					Average Price Per Share
	Number		Percent		Amount			Percent		Average Price Per Share
Existing stockholders		7,041,159		74%		$	17,579,876		54%		$	2.49
New investors		2,500,000		26%		$	15,000,000		46%		$	6.00
Total		9,541,159		100%		$	32,579,876		100%		$	3.41

If the underwriters exercise their option to purchase additional shares of our common stock in full, the percentage of shares of common stock held by existing stockholders will decrease to approximately 3% of the total number of shares of our common stock outstanding after this offering, and the number of shares held by new investors will increase to 2,875,000, or approximately 29% of the total number of shares of our common stock outstanding after this offering.

•

1,437,560 shares of common stock issuable upon exercise of warrants issued to investors in prior financings, in each case, with a weighted average exercise price equal to $2.88 per share;

•

75,000 shares of common stock issuable to certain vendors of the Company which will vest upon the satisfaction of certain performance-based and time-based vesting requirements;

•

375,000 shares of our common stock issuable upon exercise of the underwriter’s over-allotment option;

•

150,000 shares of shares of our common stock issuable upon exercise of the Underwriter Warrants; and

•

2,000,000 shares of our common stock reserved for issuance pursuant to future awards under our 2021 Equity Incentive Plan.

To the extent that outstanding exercisable options or warrants are exercised or new options or other securities are issued under our equity incentive plans, you may experience further dilution. In addition, we may choose to raise additional capital due to market conditions or strategic considerations, even if we believe we have sufficient funds for our current or future operating plans. To the extent that we raise additional capital by issuing equity securities or convertible debt, your ownership will be further diluted.

CORPORATE CONVERSION

On June 23, 2021, prior to the effectiveness of the registration statement of which this prospectus forms a part, Acurx Pharmaceuticals, LLC converted from a Delaware limited liability company into a Delaware corporation pursuant to a statutory conversion, and changed its name to Acurx Pharmaceuticals, Inc. In order to consummate the corporate conversion, a certificate of conversion was filed with the Secretary of State of the State of Delaware. In this prospectus, we refer to all transactions related to our conversion to a corporation as the Corporate Conversion.

As a result of the corporate conversion:

•

all of the outstanding Class A membership interests and all of the outstanding Class B membership interests of Acurx Pharmaceuticals, LLC became shares of common stock of Acurx Pharmaceuticals, Inc. pursuant to a conversion ratio of one-half of one share of common stock of Acurx Pharmaceuticals, Inc. for each Class A membership interest or Class B membership interest of Acurx Pharmaceuticals, LLC previously held and outstanding. Accordingly, 13,750,908 Class A membership interests and 100,000 Class B membership interests of Acurx Pharmaceuticals, LLC issued and outstanding immediately prior to the corporate conversion converted automatically into an aggregate of approximately 6,925,454 shares of common stock of Acurx Pharmaceuticals, Inc. (excluding rounding for fractional shares) as of May 25, 2021;

•

all of the outstanding warrants to purchase Class A membership interests of Acurx Pharmaceuticals, LLC became warrants to purchase shares of common stock of Acurx Pharmaceuticals, Inc. at a ratio of one-half of one share of common stock of Acurx Pharmaceuticals, Inc. for each Class A membership interest of Acurx Pharmaceuticals, LLC underlying such warrants, with the effect that warrants to purchase up to an aggregate of 2,875,119 Class A membership interests of Acurx Pharmaceuticals, LLC outstanding immediately prior to the corporate conversion automatically converted into warrants to purchase up to an aggregate of approximately 1,437,560 shares of common stock of Acurx Pharmaceuticals, Inc.; and

•

the exercise price of all of the outstanding warrants to purchase Class A membership interests of Acurx Pharmaceuticals, LLC adjusted in the same ratio as the one-half-for-one conversion ratio for outstanding warrants to purchase Class A membership interests of Acurx Pharmaceuticals, LLC noted above such that all of our outstanding warrants to purchase Class A membership interests of Acurx Pharmaceuticals, LLC which were previously exercisable at a weighted average price of $1.44 per Class A membership interest automatically adjusted such that the new exercise price for the warrants to purchase shares of common stock of Acurx Pharmaceuticals, Inc. that are outstanding is a weighted average price of $2.88 per share, subject to certain adjustment provisions included in each such warrant.

In connection with the Corporate Conversion, Acurx Pharmaceuticals, Inc. holds all property and assets of Acurx Pharmaceuticals, LLC and assumes all of the debts and obligations of Acurx Pharmaceuticals, LLC. Acurx Pharmaceuticals, Inc. is governed by a certificate of incorporation filed with the Secretary of State of the State of Delaware and bylaws, the material portions of which are described under the heading “Description of Capital Stock.” On the effective date of the Corporate Conversion, the members of the board of managers of Acurx Pharmaceuticals, LLC became the members of Acurx Pharmaceuticals, Inc.’s board of directors, and the officers of Acurx Pharmaceuticals, LLC became the officers of Acurx Pharmaceuticals, Inc.

The purpose of the Corporate Conversion was to reorganize our structure so that the entity that is offering our common stock to the public in this offering is a Delaware corporation rather than a Delaware limited liability company, and so that our existing investors own our common stock rather than equity interests in a limited liability company.

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

The following discussion and analysis provides information that we believe is relevant to an assessment and understanding of our results of operations and financial condition. You should read this analysis in conjunction with our audited and unaudited financial statements and the notes contained elsewhere in this prospectus. This discussion and analysis contains statements of a forward-looking nature relating to future events or our future financial performance. These statements are only predictions, and actual events or results may differ materially. In evaluating such statements, you should carefully consider the various factors identified in this prospectus, which could cause actual results to differ materially from those expressed in, or implied by, any forward-looking statements, including those set forth in “Risk Factors” in this prospectus. See “Special Note Regarding Forward-Looking Statements.”

Introduction

We are a clinical stage biopharmaceutical company developing a new class of antibiotics for infections caused by bacteria listed as priority pathogens by the World Health Organization (“WHO”), the U.S. Centers for Disease Control and Prevention (“CDC”) and the U.S. Food and Drug Administration (“FDA”). Priority pathogens are those which require new antibiotics to address the worldwide crisis of antimicrobial resistance (“AMR”), as identified by the WHO, CDC and FDA. The CDC estimates that, in the U.S., antibiotic-resistant pathogens infect one individual every 11 seconds and result in one death every 15 minutes. The WHO recently stated that growing antimicrobial resistance is equally as dangerous as the ongoing COVID-19 pandemic, threatens to unwind a century of medical progress and may leave us defenseless against infections that today can be treated easily. According to the WHO, the current clinical development pipeline remains insufficient to tackle the challenge of the increasing emergence and spread of antimicrobial resistance.

Our approach is to develop antibiotic candidates that block the DNA polymerase IIIC enzyme (Pol IIIC) . We believe we are developing the first Pol IIIC inhibitor to enter clinical trials. Pol IIIC is the primary catalyst for DNA replication of several Gram-positive bacterial cells. Our research and development pipeline includes clinical stage and early stage antibiotic candidates that target Gram-positive bacteria for oral and/or parenteral treatment of infections caused by Clostridium difficile (“C. difficile”), Enterococcus (including vancomycin-resistant strains (“VRE”)), Staphylococcus (including methicillin-resistant strains (“MRSA”)), and Streptococcus (including antibiotic-resistant strains).

Pol IIIC is required for the replication of DNA in certain Gram-positive bacterial species. By blocking this enzyme, our antibiotic candidates are believed to be bactericidal and inhibit proliferation of several common bacterial pathogens, including both sensitive and resistant C. difficile, MRSA, vancomycin resistant Enterococcus, penicillin-resistant Streptococcus pneumonia (“PRSP”) and other resistant bacteria.

Recent Developments

Effects of Coronavirus on Our Business

Since the start of the COVID-19 pandemic, we continued to enroll patients in our Phase 2a clinical trial of our lead antibiotic candidate, ibezapolstat, although enrollment rates decreased significantly at certain of our clinical trial sites. Other areas of our business experienced no change, including our manufacturing and research and development activities, in each case, with key vendors. We believe that the COVID-19 pandemic has highlighted the importance of antibiotic development in responding to global health issues particularly because many hospitalized COVID-19 patients were also prescribed antibiotics which only accelerates the current antimicrobial resistance crisis described by several regulatory bodies worldwide.

TABLE OF CONTENTS

In May 2020, we received a Paycheck Protection Program loan (“PPP Loan”) under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), as administered by the U.S. Small Business Administration (“SBA”) in the amount of $66,503. We did not provide any collateral or guarantees in connection with the PPP Loan, nor did we pay any facility charge to obtain the PPP Loan. The note and agreement provides for customary events of default, including those relating to failure to make payment, bankruptcy, breaches of representations and material adverse effects. We may prepay the principal of the PPP Loan at any time without incurring any prepayment charges. The PPP Loan carries an annual interest rate of 0.98% and matures two (2) years from issuance.

On April 13, 2021, the Small Business Administration authorized the full forgiveness of the PPP Loan. Upon forgiveness of the PPP Loan, we will reduce the liability and record a gain on extinguishment of debt in the statement of operations.

Recent Transactions

To date, we have raised an aggregate of $12.9 million in gross proceeds from the sale of our securities. This includes investment of approximately $955,000 by our officers and directors and approximately $12 million from other investors.

Net loss was $1.5 million for the three months ended March 31, 2021, compared to $1.3 million for the three months ended March 31, 2020, a decrease of $0.2 million, or 15%, primarily due to decreases in research and development expenses offset by the increase in general and administrative expenses for the reasons stated above.

Net Cash Used in Operating Activities

Net cash used in operating activities was $0.5 million for the three months ended March 31, 2021. The net loss for this period was greater than the net cash used in operating activities by $0.9 million, which was primarily attributable to share-based executive compensation of $0.9 million, share based compensation to the board of directors of $0.2 million, and share based vendor payments of $0.1 million, which was paid in restricted Class A membership interests, offset by an increase in deferred offering costs of $0.3 million.

Liquidity and Capital Resources

Overview

We have generated no revenue from operations and we have incurred cumulative losses of approximately $15.3 million since inception as of March 31, 2021. We have funded our operations primarily from equity issuances. We received net cash proceeds of approximately $12.9 million from equity financings closed between March 2018 and October 2020 starting with investments from the co-founders. All of our equity financings were consummated at a price ranging from $1.00 per Class A Membership Interest (March 2018) to $3.25 per Class A Membership Interest (July 2020 and October 2020). Warrant coverage was provided in all but our most-recent financing and the warrant coverage in our early-stage financings ranged from 25% warrant coverage to 50% warrant coverage, in each case, with a conversion price equal to the issue price in each offering.

Based upon our lack of revenue expected for 2021, together with the planned expenditures, management currently believes that current cash will be insufficient to fund our research and development expenses and general and administrative expenses beyond the end of 2021. Upon completion of this offering, the expected net proceeds from this offering, added to our current cash, is anticipated to be sufficient to fund our operations through the end of 2023.

TABLE OF CONTENTS

Furthermore, if our assumptions underlying our anticipated timing for the completion of our clinical and regulatory program and our anticipated expenses prove to be wrong, we may have to raise additional capital sooner than anticipated. Because of numerous risks and uncertainties associated with the research, development and future commercialization of our product candidates, we are unable to estimate with certainty the amounts of increased capital outlays and operating expenditures associated with our anticipated clinical trials and development activities. Our current estimates may be subject to change as circumstances regarding requirements further develop. We may decide to raise capital through public or private equity offerings, debt financings or corporate collaboration and licensing arrangements. We do not have any existing commitments for future external funding. We may seek to sell additional equity or debt securities or obtain a bank credit facility if available. The sale of additional equity or debt securities, if convertible, could result in dilution to our stockholders. The incurrence of indebtedness would result in increased fixed obligations and could also result in covenants that would restrict our operations or other financing alternatives.

Our ability to continue as a going concern may be dependent on our ability to raise additional capital, to fund our research and development and commercial programs and meet our obligations on a timely basis. If we are unable to successfully raise sufficient additional capital, we may not have sufficient cash flow and liquidity to fund our business operations, forcing us to delay, discontinue or prevent product development and clinical trial activities or the approval of any of our potential products or curtail our activities and, ultimately, potentially cease operations. Even if we are able to raise additional capital, such financings may only be available on unattractive terms, or could result in significant dilution of stockholders’ interests and, in such event, the value and potential future market price of our common stock may decline. In addition, the incurrence of indebtedness would result in increased fixed obligations and could result in covenants that would restrict our operations or other financing alternatives.

As of March 31, 2021, we had working capital of $2.2 million, consisting primarily of $2.6 million of cash, offset by $0.5 million of accounts payable and accrued expenses.

Recent Accounting Pronouncements

The Financial Accounting Standards Board has issued certain accounting pronouncements as of December 31, 2020 that will become effective in subsequent periods; however, we do not believe that any of those pronouncements would have significantly affected our financial accounting measurements or disclosures had they been in effect during 2020, or that they will have a significant impact on us at the time they become effective.

Critical Accounting Policies and Estimates

Use of Estimates

The preparation of financial statements in conformity with accounting standards generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates.

Federal Income Taxes

We are organized as a limited liability company, and are not a tax paying entity for Federal and state income tax purposes and, therefore, no income tax expense has been recorded in the financial statements. Our income or losses are passed through to the members for inclusion in their respective income tax returns.

Concentration of Credit Risk

We maintain our cash balance in one financial institution. The balance is insured up to the maximum allowable by the Federal Deposit Insurance Corporation (“FDIC”). We have not experienced any losses in such accounts and do not believe we are exposed to any significant risk of loss on cash. At times, the cash balance may exceed the maximum insured limit of the FDIC.

TABLE OF CONTENTS

Guaranteed Payments to Members

Guaranteed payments to our members, that were designated to represent reasonable compensation for services rendered, were accounted for as our expenses rather than an allocation of our net income.

Research and Development

In accordance with Accounting Standards Codification Topic No. 730, Accounting for Research and Development Costs, we expense research and development costs when incurred. At times, we may make cash advances for future research and development services. These amounts are deferred and expensed in the period the service is provided. We incurred net research and development expenses in the amount of $2,202,979 and $3,510,088 for the years ended December 31, 2020 and 2019, respectively, and $91,908 and $684,731 for the three months ended March 31, 2021 and 2020, respectively.

Share-Based Compensation

We account for the cost of services performed by officers and directors received in exchange for an award of our membership interests based on the grant-date fair value of the award. We recognize compensation expense on a straight-line basis over the service period.

Share-Based Payments to Vendors

In accordance with our adoption of ASU No. 2018-07, Compensation — Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, we account for the cost of services performed by vendors in exchange for an award of our membership interests based on the grant-date fair value of the award or the fair value of the services rendered; whichever is more readily determinable. Such fair value is measured as of the date the services or the date performance by the other party is complete. We recognize the expense in the same period and in the same manner as if we had paid cash for the services.

Foreign Currency Transactions

The financial statements are presented in U.S. dollars (“USD”), our reporting currency. We may engage in transactions denominated in other foreign currencies. These transactions were translated to USD at rates which approximate those in effect on the transaction dates. Monetary assets and liabilities denominated in foreign currencies at year-end will be translated at exchange rates in effect as of those dates. Nonmonetary assets and liabilities are translated at appropriate historical rates.

Major Vendor

For the year ended December 31, 2020, we had a major vendor that accounted for approximately 40% of the research and development expenditures. The same vendor also accounted for approximately 6% of the total accounts payable at December 31, 2020. This vendor is a clinical research organization (“CRO”), and has been involved with managing our clinical trials of ibezapolstat since the fourth quarter 2019. We entered into a Master Services Agreement, dated October 11, 2019 with this vendor to perform CRO services on our behalf and we signed a work order in November 2019 to retain the CRO to perform clinical trial services for our Phase 2a clinical trial of ibezapolstat. We anticipate working with the same vendor to perform CRO services in connection with our planned Phase 2b clinical trial which services would be performed pursuant to a new work order in September 2020 under the purview of the existing Master Services Agreement.

TABLE OF CONTENTS

BUSINESS

Overview

We are a clinical-stage biopharmaceutical company developing a new class of antibiotics for infections caused by bacteria listed as priority pathogens by the World Health Organization (“WHO”) the U.S. Centers for Disease Control and Prevention (“CDC”) and the U.S. Food and Drug Administration (“FDA”). Priority pathogens are those which require new antibiotics to address the worldwide crisis of antimicrobial resistance (“AMR”) as identified by the WHO, CDC and FDA. The CDC estimates that, in the U.S., antibiotic-resistant pathogens infect one individual every 11 seconds and result in one death every 15 minutes. The WHO recently stated that growing antimicrobial resistance is equally as dangerous as the ongoing COVID-19 pandemic, threatens to unwind a century of medical progress and may leave us defenseless against infections that today can be treated easily. According to the WHO, the current clinical development pipeline remains insufficient to tackle the challenge of the increasing emergence and spread of antimicrobial resistance.

Our approach is to develop antibiotic candidates that block the DNA polymerase IIIC (“Pol IIIC”). We believe we are developing the first Pol IIIC inhibitor to enter clinical trials. Pol IIIC is the primary catalyst for DNA replication of several Gram-positive bacterial cells. Our research and development pipeline includes clinical stage and early stage antibiotic candidates that target Gram-positive bacteria for oral and/or parenteral treatment of infections caused by Clostridium difficile (“C. difficile”), Enterococcus (including vancomycin-resistant strains (“VRE”)), Staphylococcus (including methicillin-resistant strains (“MRSA”)), and Streptococcus (including antibioticresistant strains).

Pol IIIC is required for the replication of DNA in certain Gram-positive bacterial species. By blocking this enzyme, our antibiotic candidates are believed to be bactericidal and inhibit proliferation of several common bacterial pathogens, including both sensitive and resistant C. difficile, MRSA, vancomycin resistant Enterococcus, penicillin-resistant Streptococcus pneumoniae (“PRSP”) and other resistant bacteria.

We intend to “de-risk” this new class of antibiotics through our drug development activities and potentially partner with a fully-integrated pharmaceutical company for late-stage clinical trials and commercialization.

Our lead antibiotic candidate, ibezapolstat (formerly named ACX-362E), has a novel mechanism of action that targets the Pol IIIC enzyme, a previously unexploited scientific target. We recently completed a Phase 2a clinical trial of ibezapolstat to treat patients with C. difficile infections, or CDI. The Phase 2a clinical trial was terminated early based upon the recommendation of our Scientific Advisory Board, or SAB. The SAB reviewed the study data presented by management, including adverse events and efficacy outcomes, and discussed their clinical impressions. The SAB unanimously supported the early termination of the Phase 2a trial after 10 patients were enrolled in the trial instead of 20 patients as originally planned. The early termination was further based on the evidence of meeting the treatment goals of eliminating the infection with an acceptable adverse event profile.

TABLE OF CONTENTS

compensation. Generally, the SAB is consulted by management during the process of designing our preclinical and clinical trials as well as in the process of analyzing data generated from these trials, although the SAB’s services are not limited to such activities.

Currently available antibiotics used to treat CDI infections utilize other mechanisms of action. We believe ibezapolstat is the first antibiotic candidate to work by blocking the DNA Pol IIIC enzyme in C. difficile. This enzyme is necessary for replication of the DNA of certain Gram-positive bacteria, like C. difficile.

As of May 25, 2021, we had two full-time employees and one part-time employee.

Our Technology

These results also represent the first-ever clinical validation of DNA polymerase IIIC as a therapeutically relevant antibacterial target. Ibezapolstat was very well tolerated with no treatment-related SAEs noted in the Phase 2a trial. Additionally, data obtained to date demonstrate that ibezapolstat enhances actinobacteria in the microbiome and suppresses regrowth of proteobacteria; potentially lessening the likelihood of CDI recurrence or new infection by MDR Gram-negative bacteria (Garey, et. al., Late-Breaker Presentation, Ibezapolstat Clinical Update, 8th Annual International C. Diff. Virtual Conference, November 14, 2020).

[MISSING IMAGE: tm2111636d2-tbl_activ4c.jpg]

Prior to conducting the Phase 2a clinical trial, we successfully completed a Phase 1 clinical trial of ibezapolstat for the oral treatment of CDI (the “Phase 1 Trial”). The Phase 1 Trial, conducted in the U.S., was a double-blind, placebo- controlled study to determine safety, tolerability, pharmacokinetics and fecal concentrations of ibezapolstat in 62 healthy volunteers. It was conducted in two parts; first, single ascending doses were administered to four cohorts of eight subjects each, and second, multiple ascending doses were administered that simulate the anticipated clinical treatment regimen. Safety information was analyzed through assessment of adverse events and other standard safety measures, while concentrations of ibezapolstat were determined in both blood and the feces, the latter being the critical site of drug delivery for treating CDI. In addition, the laboratory of Dr. Kevin Garey at the University of Houston performed state-of-the-art microbiomic testing of gastrointestinal flora in trial subjects as compared with vancomycin, the standard of care for the treatment of patients with CDI, which testing was the first of its kind in Phase 1 clinical trials for CDI.

Data from the case report forms completed by the principal investigators of the Phase I Trial showed that single and multiple ascending doses of ibezapolstat demonstrated a safety signal similar to placebo according to the principal investigators as evidenced by the case report forms. There were no safety signals reported on the case report forms related to physical examination or vital signs (blood pressure, pulse or oral temperature) in any part of the study. No significant abnormalities developed in the 12-lead electrocardiogram traces for any subject at any dose given according to the data reported by the principal investigators in the case report forms. No changes were observed in serum biochemistry or haematological blood evaluations. No

TABLE OF CONTENTS

dose-dependent increase in adverse events, (each, an “AE”) was reported, and no serious AEs were observed. The proportion of ibezapolstat-dosed subjects with an AE was similar to placebo at each dosing level. All AEs were considered mild or moderate and none required a change in therapy or intervention.

Systemic exposure following oral dosing was very low and no accumulation occurred after ten days of repeated dosing. In addition, oral dosing of ibezapolstat resulted in rapid and sustained fecal concentrations that are approximately 2,500 times the minimum inhibitory concentration of ibezapolstat required to kill the CDI bacteria in the colon at the site of the infection. Comparative microbiome analysis versus vancomycin demonstrated a two to three log favorable difference in the reduction of the predominantly healthy bacteria in the gut microbiome. Free concentrations of ibezapolstat were found to be high enough to kill C. difficile but too low to kill healthy bacteria like Bacteroides & Firmicutes which constitute approximately 90% of healthy microbiome in the judgment of our scientific advisors. Upon review of the final Phase 1 Trial data, our medical and scientific advisors suggested these data supported advancing ibezapolstat into a Phase 2 clinical trial at doses up to 450 mg, twice daily, for 10 days of treatment, as described above. We believe that ibezapolstat is the only clinical-stage compound currently known to target C. difficile by acting specifically on Pol IIIC.

We have worked closely with the FDA to obtain our investigational new drug application (“IND”), and to obtain FDA fast track designation as well as designation of ibezapolstat as a qualified infectious disease product (“QIDP”), which provides incentives through the Generating Antibiotic Incentives Now Act (the “GAIN Act”) including FDA priority review for the first application submitted for the QIDP, fast track designation eligibility and extension of statutory exclusivity periods in the U.S. for an additional 5 years upon FDA marketing approval of the product to treat patients with CDI.

Ibezapolstat originally was sponsored by GLSynthesis Inc., which completed several pre-clinical studies, developed the current manufacturing process and filed for the patents that have been granted to date. We acquired worldwide rights to manufacture, develop and commercialize ibezapolstat from GLSynthesis Inc. on February 5, 2018, pursuant to an asset purchase agreement executed by the parties on that date. At closing, we paid GLSynthesis $110,174 in cash and 100,000 Class B Membership Interests. We are also required to pay up to $700,000 in success-based clinical milestone payments to GLSynthesis, including a payment of $500,000 upon the successful completion of two phase 3 clinical trials and a royalty of 4% on net sales of ibezapolstat throughout the duration of the patent period, which currently extends to September 2030.

As of the date of this prospectus, of the $700,000 of potential milestone payments, we have paid to GLSynthesis a total of $50,000, including $25,000 paid upon receipt of a “safe to proceed” notification from FDA relating to the commencement of clinical trials (December 2018) and $25,000 paid upon the successful completion of clinical trial drug supply suitable to support our Phase 1 clinical trial (December 2018). The patent jurisdictions of the acquired patents include the U.S., European Union, Japan and Canada.

About QIDP and Fast Track Designations

The Generating Antibiotic Incentives Now (GAIN) Act, which was enacted as part of the Food and Drug Administration Safety and Innovation Act (“FDASIA”) in 2012, created incentives for the development of novel antibiotic and antifungal products intended to treat serious and life-threatening infections. The GAIN Act amended the federal Food, Drug, and Cosmetic Act to add a designation for QIDPs. A QIDP is defined as “an antibacterial or antifungal drug for human use intended to treat serious or life-threatening infections, including those caused by (1) an antibacterial or antifungal resistant pathogen, including novel or infectious pathogens, or (2) qualifying pathogens listed under” 21 C.F.R. § 317.2. The primary incentive for developing a QIDP is a five-year exclusivity extension for the relevant antibiotic or antifungal indications of the QIDP, but the designation also offers FDA priority review for the first application submitted for the QIDP and eligibility for fast track designation.

FDA’s fast track designation is a process designed to facilitate the development and expedite the regulatory pathway of new drugs to treat serious or life-threatening conditions and that fill a high unmet medical need. To be eligible for a fast track designation, the FDA must determine, based on the request of a sponsor, that a product is intended to treat a serious or life-threatening disease or condition and demonstrates the potential to address an unmet medical need by providing a therapy where none exists or a

TABLE OF CONTENTS

therapy that may be potentially superior to existing therapy based on efficacy or safety factors. Fast track designation provides opportunities for more frequent interactions with the FDA review team to expedite development and review of the product. The FDA may also review sections of the new drug application (“NDA”) for a fast track product on a rolling basis before the complete application is submitted, if the sponsor and the FDA agree on a schedule for the submission of the application sections and the sponsor pays any required user fees upon submission of the first section of the NDA. In addition, fast track designation may be withdrawn by the sponsor or rescinded by the FDA if the designation is no longer supported by data emerging from the clinical trial process.

Ibezapolstat is a novel, orally-administered antibacterial compound. It is the first of a novel class of DNA polymerase IIIC inhibitors under development by us to treat bacterial infections. Ibezapolstat has been designated by the FDA as a QIDP for the treatment of patients with CDI and will be eligible to benefit from the incentives for the development of new antibiotics established under the GAIN Act. Ibezapolstat is being developed as a targeted, narrow spectrum oral antibiotic for the treatment of patients with CDI. In addition, ibezapolstat has received fast track designation from FDA. We successfully completed the Phase 1 clinical trial in August 2019 and have completed a Phase 2a clinical trial and expect to begin a Phase 2b clinical trial in 2021. The CDC has designated C. difficile as an urgent threat highlighting the need for new antibiotics to treat CDI.

Based upon advice from our scientific advisors, we believe ACX-375C, our second antibiotic candidate currently in pre-clinical development, will also be eligible for FDA’s QIDP and fast track designations. This advice is supported by the “qualifying” criteria for a QIDP (Qualified Infectious Disease Product) listed in GAIN Act legislation of 2012 enacted as part of the Food and Drug Administration Safety and Innovation Act (FDASIA). A QIDP is defined as “an antibacterial or antifungal drug for human use intended to treat serious or life-threatening infections, including those caused by qualifying pathogens listed under 21 C.F.R. § 317.2 which include bacterial pathogens against which ACX-375C has demonstrated microbiological activity namely, methicillin-resistant Staphylococcus aureus and vancomycin-resistant enterococcus. These bacteria are generally causative of serious or life-threatening infections, including, but not limited to, acute bacterial skin and skin structure infections, community acquired pneumonia, blood stream infections, hospital acquired bacterial pneumonia and ventilator acquired bacterial pneumonia, which are planned to be studied in future clinical trials at the appropriate time in product development.

Mechanism of Action

DNA Pol IIIC has proved essential for replicative DNA synthesis in aerobic, low G-C Gram-positive bacteria, i.e. those with a low guanine-cytosine (G-C) ratio relative to their adenine-thymine (A-T) ratio. Pol IIIC-specific genes of several such Gram-positive bacteria have been cloned and expressed, and the DNA Pol IIIC enzymes appear to share a unique capacity to be inhibited by 6-anilinouracils (AU), 2-phenylguanines (PG) and related compounds which are analogs of 2 ‘-deoxyguanosine 5’ -triphosphate (dGTP).

The hypothesis supporting further development of ibezapolstat is that dGTP analog compounds bind to Pol IIICvia a “base-pairing domain” and an enzyme-specific “aryl domain” (Figure 1). Through its base-pairing domain, which mimics that of guanine, the dGTP analog base pairs with an un-apposed template cytosine just distal to the DNA primer terminus. Simultaneously, the aryl domain binds an aryl-specific “receptor” near the POL IIIC enzyme’s dNTP binding site, causing the formation of an inactive ternary complex of inhibitor (dGTP analog), DNA and Pol IIIC (Figure 2).

[MISSING IMAGE: tm2111636d1-tbl_mecha4clr.jpg]

Following the ternary binding hypothesis described above, Torti et al. (2011) reported that ibezapolstat (362E) inhibited purified Pol IIIC derived from C. difficile (Ki 0.325 µM) and from Bacillus subtilis (Ki 0.34 µM) in in vitro resting. C. difficile has a single circular chromosome and one origin of replication (oriC) from which DNA replication begins in a bi-directional fashion (Figure 3A). Using marker frequency analysis, the abundance of the oriC proximal genes relative to the terminus (terC) proximal genes can be determined. C. difficile treated with 4 µg/mL of ibezapolstat (362E) demonstrated an 8-16-fold increased oriC:terC ratio, which would be expected for inhibition of DNA replication (Figure 3B).

Pharmacokinetics

Administration in male rats of a 5 mg/kg IV bolus dose of a salt form of GLS362E showed rapid systemic clearance and a short terminal half-life (0.34 hours). Plasma concentrations were BQL (<0.5ng/mL) at three to four hours post-dose. All oral dosing of GLS362E, now known as ibezapolstat, did not use the salt form, only the parent molecule since the salt form is not necessary for oral dosing. Administration in male rats of a single 50mg/kg oral dose of ibezapolstat in a suspension formulation, Cmax was 119ng/mL and was observed at 15 minutes post-dose. Plasma levels declined with an apparent terminal half — life of 3.82 hours and were still quantifiable at 24 hours post-dose. Oral bioavailability in male rats was 8.6%. Ibezapolstat excretion in feces was much greater than urinary excretion, consistent with incomplete oral bioavailability. After administration in male rats of a single 50 mg/kg oral dose of ibezapolstat in a suspension formulation, concentrations in the GI mucosa of all regions of the gastrointestinal tract were >10µg/mL at four hours post-dose, and >10 µg/mL at ten hours post-dose for ileum, cecum, colon and rectum. Fecal concentrations after oral dosing were approximately 100 to 200 mcg/mL.

In vitro Microbiology

Several in vitro susceptibility tests have been completed. Below is a summary data table showing MIC values for 22 C. difficile strains, conducted in triplicate, with the testing conducted by the R.M. Alden Laboratory in California and the isolates obtained from the same. The table below shows that the activity of GLS362E was similar to that of vancomycin and metronidazole.

Data in the table below show that ibezapolstat was not active against two Bifidobacterium species or Eubacterium lentum at 32 µ g/mL, the highest concentration tested. Activity was observed for lactobacilli and Clostridium perfringens. Most importantly, ibezapolstat was active against ten clinical isolates of C. difficile with an MIC range of 0.5 – 4 µ g/mL, MIC50 of 2 µ g/mL, and an MIC90 of 4 µ g/mL. Since the Pol IIIC target enzyme is present in only a narrow spectrum of Gram-positive organisms, minimal disruption of gut flora is anticipated. This is supported by the data in the table below, which shows that representative specimens of other gut bacteria — lactobacillus, bifidobacterium, and eubacterium — are not susceptible to ibezapolstat.

The in vitro activity of ibezapolstat was tested in June 2019 by conducting minimum inhibitory concentration (MIC) testing against 104 C. difficile clinical isolates, including those with important ribotypes. Fidaxomicin, vancomycin, and metronidazole were used as comparators. When ibezapolstat achieved the ≥99.9% bacterial kill (i.e., 3-log reduction in bacterial numbers), it met the Clinical Laboratory Standards Institute (“CLSI”) criteria for bactericidal activity which is accepted by FDA. This represents a laboratory measure of antibacterial potency but does not translate directly into human efficacy which can only be established in clinical trials.

Results indicated that the activity of ibezapolstat was similar to that of the comparators evaluated, with a narrow MIC range against 104 C. difficile clinical isolates, of which ~30% were of different ribotypes

TABLE OF CONTENTS

and another 30% were toxigenic. In addition, 4 isolates of the epidemic strain ribotypes 027 and 078 demonstrated ACX-362E sensitivities similar to those of other ribotypes. In Vitro Activity (in μg/mL) of ACX-362E (ibezapolstat) and Comparators against 104 C. dificile Clinical Isolates.

Overall, the results of this study indicated that the activity of ibezapolstat was similar to that of the comparators evaluated in this study. With a narrow MIC range against 104 C. difficile clinical isolates, approximately 30% were of different ribotypes and another 30% were toxigenic.

In July 2019 the bactericidal activity of ibezapolstat was evaluated by first determining the MIC and then the minimum bactericidal concentration (MBC) against 3 C. difficile isolates; vancomycin and metronidazole were used as comparators in these assays. In a second measure of bactericidal activity, the time-kill kinetics of ibezapolstat was assessed in comparison to vancomycin and metronidazole against the same 3 C. difficile isolates.

Against two of the three isolates, ibezapolstat had MBC:MIC ratios of 1 to 4 across replicates indicating bactericidal activity. For the remaining isolate, MBC:MIC ratios of 2 to >8 were observed although in instances where the ratio was >8, counts indicated >2-log10 killing at or near the MIC. When the time-kill kinetics (or the result of a microbiological laboratory study of antimicrobial activity of a compound over time) of ibezapolstat were evaluated against C. difficile MMX 5680 and BAA-1382, bactericidal activity was observed at the two later time points and at all three evaluated doses (MMX 5680) or the two highest doses (BAA-1382). Against C. difficile isolate BAA-1875, ibezapolstat did not demonstrate the ≥3 log10 CFU/mL killing required for bactericidal activity, but bacterial levels were reduced by >2 log10 CFU at the 24- and 48-hr time points at 16X and 32X the MIC. In the case of metronidazole and vancomycin, the highest MIC value recorded from the triplicate testing was used to calculate 8X, 16X, and 32X the MIC for the time kill study.

Counts only slightly exceeded the rejection values for 3-log killing (indicating that 3-log killing was nearly achieved)

Nonclinical data indicate that ibezapolstat demonstrates reproducible and consistent in vitro potency against C. difficile and is comparable to vancomycin in the standard and predictive Syrian Golden Hamster model of CDI. The nonclinical data also indicate that ibezapolstat may be active against C. difficile in the human colon, and in fact, ibezapolstat concentrations reached approximately 2,500-fold greater than the MIC needed to kill the C. difficile in this Phase 1 first-in-man clinical trial.

In vivo Efficacy Animal Models

GLS362E (and GLS359E) were studied in vivo in the golden Syrian hamster model of C. difficile-induced colitis. Both compounds had low GI absorption (<5% of an oral dose of 75 mg/kg was absorbed) and low toxicity (up to 1,000 mg/kg in hamsters). In the in vivo model, hamsters are first treated subcutaneously with clindamycin, followed 24 h later with ~107 CFU of C. difficile spores administered orally; therapy was initiated ~17 hours post-infection. Initial experiments evaluated the efficacy of the two compounds in this model (Dvoskin, et al, 2012, AAC) with studies designed to optimize the dose and length of therapy. In experiment 1 (shown in Table 2, below), treatment was given twice daily for three days with either vancomycin (50 mg/kg),

[MISSING IMAGE: tm2111636d1-lc_animal4clr.jpg]

GLS359E or GLS362E (GLS359E and GLS362E dosed at 50, 25, 12.5, or 6.25 mg/kg), with survivorship followed through 120 hours. 362E was found to be more efficacious at lower doses than GLS359E: 6.25 mg/kg of 362E was superior to an equivalent dose of GLS359E (P<0.001). For this reason, GLS362E was profiled further.

Subsequent experiments extended the length of therapy for GLS362E to 7 or 14 days because in the experiment shown in Table 2 it was observed that survival was not maintained beyond five days after the end of treatment in any group; studies were then designed to evaluate recurrence rates. Table 2 displays (below, from Dvoskin, et. al, 2012, AAC) twice-daily treatment for three days with either GLS-362E (50 mg/kg) or vancomycin (50 mg/kg), 67% of treated animals died. When treatment with GLS362E is extended to 7 or 14 days, survival increased to 60 and 100%, respectively. Upon necropsy, the intestinal contents of surviving hamsters were negative for toxin A and/or B whereas those for animals that had died were positive. /The results for the 3-day dosing shown in Table 2 above were from additional studies. Other studies conducted by Dvoskin et al. evaluated GLS362E efficacy/recurrence rates in the hamster model at lower doses: after 14 days of dosing (100% survival for all groups at 25, 12.5 and 6.25 mg/kg out to 36 days; negative for A/B toxins): after 10 days of dosing at 10 mg/kg, GLS362E treatment resulted in 86% survival on Day 36 post-infection,

C. difficile Infection Overview

Clostridioides difficile infection (“CDI”) is a bacterial infection of the colon that produces toxins causing inflammation of the colon and severe diarrhea. CDI can also result in more serious disease complications, including pseudomembranous colitis, bowel perforation, toxic megacolon and sepsis. CDI represents a serious healthcare issue in hospitals, long-term care homes and, increasingly, in the wider community. We estimate that there are over one million cases of CDI each year in the U.S. and Europe, based on an epidemiology report on CDI that was published in 2015 by Decision Resources, a healthcare research and consulting company. In addition, CDI is responsible for approximately 29,000 deaths per year in the U.S., according to a study published in the New England Journal of Medicine in 2015. A separate study published in 2018 in Clinical Microbiology and Infection, a peer reviewed journal published by the European Society of Clinical Microbiology and Infectious Diseases, indicated that CDI may be underdiagnosed in approximately 25% of cases. A study published in The Journal of Hospital Infection, a peer reviewed journal published by the Healthcare Infection Society, reported that CDI is two to four times more common than hospital associated infections caused by methicillin-resistant Staphylococcus aureus, a bacterium frequently associated with such infections. The Healthcare Cost and Utilization Project, a family of databases developed through a federal-state-industry partnership sponsored by the Agency for

TABLE OF CONTENTS

Healthcare Research and Quality of the U.S. Department of Health and Human Services, reported an approximate three and one-half-fold increase in hospital stays associated with CDI between 2000 and 2008. The economic impact of CDI is significant. A study published in 2012 in Clinical Infectious Diseases estimated that acute care costs for CDI total $4.8 billion per year in the U.S. alone. According to the 2017 Update (published February 2018) of the Clinical Practice Guidelines for C. difficile Infection by the Infectious Diseases Society of America (IDSA) and Society or Healthcare Epidemiology of America (SHEA), CDI remains a significant medical problem in hospitals, in long-term care facilities and in the community. C. difficile is one of the most common causes of health care-associated infections in U.S. hospitals (Lessa, et al, 2015, New England Journal of Medicine). Recent estimates suggest C. difficile approaches 500,000 infections annually in the U.S. and is associated with approximately 20,000 deaths annually. (Guh, 2020, New England Journal of Medicine). Based on internal estimates, the recurrence rate of two of the three antibiotics currently used to treat CDI is between 20% and 40% among approximately 150,000 patients treated. We believe the annual incidence of CDI in the U.S. approaches 600,000 infections and a mortality rate of approximately 9.3%. There are an additional six million patients in the U.S. per year with other Gram+ infections, such as Staphylococcus, Streptococcus or Enterococcal, with approximately 300,000 patients treated for such infections.

CDI originates from a bacterium known as Clostridium difficile, or Clostridioides difficile, or C. difficile.

C. difficile can be a harmless resident of the gastrointestinal tract. The complex community of microorganisms that make up the natural gut flora usually moderates levels and pathogenicity of C. difficile. The natural gut flora is an essential part of the normal function of the gastrointestinal tract and also has wide implications to human health, such as the proper function of the immune system. CDI typically develops following the use of broad-spectrum antibiotic agents that can cause widespread damage to the natural gut flora and allow overgrowth of C. difficile. Hypervirulent C. difficile strains have also emerged and are frequently associated with more severe disease. In the U.S., the hypervirulent strain, ribotype 027, accounts for approximately one-third of all CDI cases.

An important clinical issue with CDI is disease recurrence. This is in contrast to other bacterial threats for which drug resistance is the principal concern. According to an article published in 2012 in the peer reviewed journal Clinical Microbiology and Infection, 20% to 40% of patients with CDI suffer a second episode of the infection. The risk of further recurrence rises to 65% after a patient suffers a third episode of CDI. In addition, each episode of recurrent disease is associated with greater disease severity and higher mortality rates. Recurrent disease is associated with an increased burden on the healthcare system.

In 2013, and again in a 2019 Update, the CDC highlighted C. difficile as one of five pathogens that pose an immediate public health threat and require urgent and aggressive action. In 2012, the GAIN Act provisions became law along with the rest of FDASIA. The goal of the GAIN Act is to encourage the development of new antibiotics that treat specific pathogens, including C. difficile, which cause serious and life-threatening infections. Since the GAIN Act was adopted, there have been two antibiotic candidates developed for CDI that have been granted QIDP status under the GAIN Act, one of which was approved by the FDA in 2011. See “Current CDI Antibiotic Treatments” below.

Current CDI Antibiotic Treatments

Current treatment options for CDI are limited. The current standard-of-care for CDI is treatment with vancomycin or off label use of metronidazole, both of which are broad-spectrum antibiotics. Although these antibiotics reduce levels of C. difficile, both also cause significant collateral damage to the gut flora as a result of their broad spectrum of activity. This collateral damage to the gut flora leaves patients vulnerable to recurrent CDI. A review published in 2012 in the peer reviewed journal International Journal of Antimicrobial Agents reported recurrence rates of 24.0% for vancomycin and 27.1% for metronidazole. Metronidazole is frequently used in mild or moderate cases of CDI and has been associated with a number of side effects. The 2017 Update (published February 2018) of the Clinical Practice Guidelines for C. difficile Infection by the Infectious Diseases Society of America (IDSA) and Society of Healthcare Epidemiology of America (SHEA) provides a recommendation for clinicians to prescribe either vancomycin or fidaxomicin over metronidazole for an initial episode of CDI.

TABLE OF CONTENTS

Fidaxomicin (Dificid) is an antibiotic approved to treat patients with CDI in the U.S. and the European Union, but it has not been shown to be superior to vancomycin in the treatment of patients with the hypervirulent strain ribotype 027. Fidaxomicin (Dificid) was approved by FDA in 2011. In July 2013, Optimer Pharmaceuticals, Inc., the sponsor of the fidaxomicin program, was sold to Cubist Pharmaceuticals for $535 million plus up to $266 million in contingent value right (“CVR”) payments post-closing. Fidaxomicin was the first antibacterial drug the FDA approved in more than 30 years to treat CDI.

Summit Therapeutics has a clinical stage antibiotic, ridinilazole, and in January 2019 had opened enrollment of a Phase 3 clinical trial to treat patients with CDI. The ridinilazole Phase 3 program includes two randomized trials testing efficacy in CDI versus vancomycin as the positive control. The trials appear to be identical in design and plan to enroll 680 patients each. Ridinilazole is an orally administered small molecule antibiotic designed to selectively target C. difficile bacteria without causing collateral damage to the gut flora and thereby reduce CDI recurrence rates. Ridinilazole has completed two Phase 2 clinical trials successfully meeting or exceeding its primary efficacy endpoints.

Despite the advances of the ridinilazole development program and the approval of fidaxomicin to treat CDI, the CDC continues to cite it as an urgent need for new antibiotics.

Clinical Strategy

Based on advice from our medical and scientific consultants and advisors, we believe we will need to conduct one Phase 2 clinical trial prior to conducting one or two large Phase 3 clinical trials in order to file a new drug application with the FDA for the oral use of ibezapolstat to treat patients with CDI. The trial design and anticipated size of the required clinical trials is as follows:

[MISSING IMAGE: tm2111636d1-tbl_clinic4clr.jpg]

Phase 1 Clinical Trial: Data reported in August 2019.

The Phase 1 clinical trial design was a randomized, double-blind, placebo-controlled, single and multiple ascending dose trial to determine the safety, pharmacokinetics and fecal microbiological effects of ibezapolstat administered orally to 62 healthy adults 18 years of age or older. For the single-dose ascending portion of the trial, the objectives were to evaluate the safety and determine the pharmacokinetics and systemic exposure of single doses as well as the effects of food on PK. The multiple ascending dose portion of the trial evaluated the safety, PK and fecal concentrations of repeated doses as well as evaluate the effects of ibezapolstat on characteristics of the gut microbiome in comparison to the current standard of care treatment antibiotic, oral vancomycin. We successfully completed the Phase 1 clinical trial in August 2019 and the data supported advancing to Phase 2 according to our medical and scientific advisors. Blood levels of ibezapolstat show low systemic exposure, as predicted by previously conducted animal studies and are desirable in treating CDI, and fecal concentrations of ibezapolstat were 2 to 3 orders of magnitude above the level required to kill CDI bacteria at the site of the infection.

Phase 2 Clinical Trial.

The Phase 2 clinical trial design is structured as a randomized, controlled Phase 2 trial of the efficacy and safety of ibezapolstat compared to vancomycin in the treatment of CDI in a total of up to 84 evaluable

TABLE OF CONTENTS

patients (Phase 2a; up to 20 patients; Phase 2b; 64 patients). Phase 2a was designed to enroll up to 20 patients with a data review planned by a Trial Oversight Committee after 10 patients completed the trial.

Based upon the recommendation of the SAB, we terminated enrollment in Phase 2a early and will advance to Phase 2b. The SAB unanimously supported the early termination of the Phase 2a trial after 10 patients were enrolled in the trial instead of 20 patients as originally planned. The early termination was further based on the evidence of meeting the treatment goals of eliminating the infection with an acceptable adverse event profile.

The SAB noted that 10 out of 10 patients enrolled in the Phase 2a trial reached the Clinical Cure endpoint, defined in the study protocol as the resolution of diarrhea in the 24-hour period immediately before the end-of-treatment that is maintained for 48 hours after end of treatment. Such cure was sustained, meaning that the patients showed no sign of infection recurrence, for 30 days thereafter. This constitutes a 100% response rate for the primary and secondary endpoints of the trial. All 10 patients enrolled in the Phase 2a trial met the study’s primary and secondary efficacy endpoints, namely, Clinical Cure at end of treatment and Sustained Clinical Cure of no recurrence of CDI at the 28-day follow-up visit. No treatment-related serious adverse events were reported by the investigators who enrolled patients in the trial. We believe these results represent the first-ever clinical data showing Pol IIIC has potential as a therapeutically-relevant antibacterial target. The Phase 2b portion of the Phase 2 clinical trial is designed as a 64-patient vancomycin- controlled efficacy study. 32 of the patients will receive 450mg of ibezapolstat twice per day, and 32 of the patients will receive 125mg of vancomycin four times per day. Both groups of patients will receive this treatment for 10 days. Phase 2b is expected to begin in the second half of 2021.

Phase 3 Clinical Trial(s).

We intend to meet with the FDA after completing the Phase 2B clinical trial to finalize the size and scope of the Phase 3 clinical trial program. Regulatory precedent indicates that two Phase 3 trials of approximately 400 patients each would need to be conducted.

Regulatory Status

The regulatory timeline for a newly proposed product can take eight to ten years from pre-clinical studies through marketing approval. However, we inherited the manufacturing and pre-clinical data generated by the prior sponsor of our lead product candidate which we believe will reduce the timeline for regulatory approval by two to three years.

We have worked closely with the FDA to obtain our IND, and to obtain FDA fast track designation as well as designation of ibezapolstat as a QIDP, which provides incentives through the GAIN Act including FDA priority review for the first application submitted for the QIDP, fast-track designation eligibility and extension of statutory exclusivity periods in the U.S. for an additional five years upon FDA approval of the product for the treatment of CDI.

Government Regulation

The research, development, testing, manufacture, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution, marketing, among other things, of drug products are extensively regulated by governmental authorities in the U.S. and other countries. The processes for obtaining regulatory approvals in the U.S. and in foreign countries and jurisdictions, along with subsequent compliance with applicable statutes and regulations and other regulatory requirements, require the expenditure of substantial time and financial resources.

TABLE OF CONTENTS

U.S. Government regulation of drug products

In the U.S., the FDA regulates human drugs under the Federal Food, Drug, and Cosmetic Act (“FDCA”), and its implementing regulations. Failure to comply with the applicable U.S. requirements may subject an applicant to administrative or judicial sanctions, such as FDA refusal to approve pending NDAs, or the agency’s issuance of warning letters, or the imposition of fines, civil penalties, product recalls, product seizures, total or partial suspension of production or distribution, injunctions and/or criminal prosecution brought by the FDA and the U.S. Department of Justice or other governmental entities.

The process required by the FDA before a drug may be marketed in the United States generally involves the following:

•

completion of preclinical laboratory tests, animal studies and formulation studies according to Good Laboratory Practices (“GLP”), regulations or other applicable regulations;

•

submission to the FDA of an IND, which must become effective before human clinical trials may begin;

•

approval by an independent institutional review board (“IRB”), or ethics committee at each clinical trial site before each clinical trial may be initiated;

•

performance of adequate and well-controlled human clinical trials in accordance with applicable IND regulations, good clinical practice regulations and standards (“GCP”), and other clinical-trial related regulations to evaluate the safety and efficacy of the investigational product for each proposed indication;

•

submission to the FDA of an NDA for marketing approval, including payment of application user fees;

•

satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the drug is produced to assess compliance with current good manufacturing practice regulations (“cGMP”), to assure that the facilities, methods and controls are adequate to preserve the product’s identity, strength, quality and purity;

•

potential FDA audit of the clinical trial sites to assure compliance with GCP and the integrity of the clinical data submitted in support of the NDA; and

•

FDA review and approval of the NDA, including satisfactory completion of an FDA advisory committee review of the product candidate, where appropriate or if applicable, prior to any commercial marketing or sale of the product in the United States.

Before testing any drug product candidate in humans, the product candidate must undergo rigorous preclinical testing. The preclinical developmental stage generally involves laboratory evaluations of drug chemistry, formulation and stability, as well as studies to evaluate toxicity in animals, which support subsequent clinical testing. The sponsor must submit the results of the preclinical studies, together with manufacturing information, analytical data, any available clinical data or literature and a proposed clinical protocol, to the FDA as part of the IND. An IND is a request for authorization from the FDA to administer an investigational product to humans, and must become effective before human clinical trials may begin.

Preclinical studies include laboratory evaluation of product chemistry and formulation, as well as in vitro and animal studies, to assess the potential for adverse events and in some cases to establish a rationale for therapeutic use. The conduct of preclinical studies is subject to federal regulations and requirements, including GLP regulations for safety and toxicology studies.

All clinical trials must be conducted under the supervision of qualified investigators and in accordance with protocols detailing the objectives of the study, the parameters to be used in monitoring the safety and effectiveness criteria to be evaluated. Each protocol must be submitted to the FDA as part of the IND and each study subject must sign an informed consent form before participating in a clinical trial. An IND automatically becomes effective 30 days after receipt by the FDA, unless before that time the FDA raises concerns or questions related to one or more proposed clinical trials and places the clinical trial on a clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the

TABLE OF CONTENTS

clinical trial can begin. Clinical holds may be imposed by the FDA at any time before or during studies due to safety concerns or non-compliance.

In addition, an IRB representing each institution that is participating in the clinical trial must review and approve the plan for any clinical trial before it commences at that institution, and the IRB must thereafter conduct a continuing review and reapprove the trial at least annually.

Human clinical trials are typically conducted in three sequential phases that may overlap or be combined:

Phase 1: The product candidate is initially introduced into healthy human subjects and tested for safety, dosage tolerance, absorption, metabolism, distribution and excretion. In the case of some products for severe or life-threatening diseases, such as cancer, especially when the product may be too inherently toxic to ethically administer to healthy volunteers, the initial human testing is often conducted in patients.

Phase 2: This phase involves studies in a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate the efficacy of the product for specific targeted diseases and to determine dosage tolerance and optimal dosage.

Phase 3: Clinical trials are undertaken with an expanded patient population to further evaluate dosage, clinical efficacy and safety in an expanded patient population, often at geographically dispersed clinical study sites. These studies are intended to establish the overall risk-benefit ratio of the product candidate and provide, if appropriate, an adequate basis for product labeling. These trials may include comparisons with placebo and/or other comparator treatments. The duration of treatment is often extended to mimic the actual use of a product during marketing.

Post-approval trials, sometimes referred to as Phase 4 clinical trials, may be conducted after initial marketing approval. These trials are used to gain additional experience from the treatment of patients in the intended therapeutic indication. In certain instances, the FDA may mandate the performance of Phase 4 clinical trials as a condition of approval of an NDA.

Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and more frequently if serious adverse events, or SAEs, occur. The FDA or the sponsor may suspend or terminate a clinical trial at any time on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the clinical protocol, GCP, or other IRB requirements or if the drug has been associated with unexpected serious harm to patients.

Assuming successful completion of the required clinical testing, the results of the preclinical studies and clinical trials, along with information relating to the product’s chemistry, manufacturing, and controls and proposed labeling, are submitted to the FDA as part of an NDA requesting approval to market the product for one or more indications. Under federal law, the fee for the submission of an NDA for which clinical data is substantial (for example, for FY2021 this application fee exceeds $2.8 million), and the sponsor of an approved NDA is also subject to an annual program fee, currently more than $300,000 per program. These fees are typically adjusted annually, but exemptions and waivers may be available under certain circumstances.

Under the goals and policies agreed to by the FDA under the Prescription Drug User Fee Act (“PDUFA”), for original NDAs, the FDA has ten months from the filing date in which to complete its initial review of a standard application and respond to the applicant, and six months from the filing date for an application with priority review. For an all new molecular entity (“NME”), NDAs, the ten and six-month time periods run from the filing date; for all other original applications, the ten and six-month time periods run from the submission date. Despite these review goals, it is not uncommon for FDA review of an NDA to extend beyond the goal date.

Before approving an NDA, the FDA will typically conduct a pre-approval inspection of the manufacturing facilities for the new product to determine whether the manufacturing processes and facilities comply with cGMP. The FDA will not approve the product unless it determines that the

TABLE OF CONTENTS

manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. The FDA also may inspect the sponsor and one or more clinical trial sites to assure compliance with GCP requirements and the integrity of the clinical data submitted to the FDA.

The FDA reviews an NDA to determine, among other things, whether a product is safe and effective for its intended use and whether its manufacturing is cGMP-compliant to assure and preserve the product’s identity, strength, quality and purity. On the basis of the FDA’s evaluation of the NDA and accompanying information, including the results of the inspection of the manufacturing facilities, the FDA may issue either an approval letter or a Complete Response Letter (“CRL”). An approval letter authorizes commercial marketing of the product with specific prescribing information for specific indications. A CRL indicates that the review cycle of the application is complete and the application will not be approved in its present form and outlines the deficiencies in the submission that must be addressed for the FDA to reconsider the application. If and when those deficiencies have been addressed to the FDA’s satisfaction in a resubmission of the NDA, the FDA will issue an approval letter.

Following approval of a new product, the manufacturer and the approved product are subject to pervasive and continuing regulation by the FDA, including, among other things, monitoring and recordkeeping activities, reporting of adverse experiences with the product, product sampling and distribution restrictions, complying with promotion and advertising requirements, which include restrictions on promoting drugs for unapproved uses or patient populations (i.e., “off-label use”) and limitations on industry-sponsored scientific and educational activities. Once a drug is granted approval, the FDA may withdraw the approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in mandatory revisions to the approved labeling to add new safety information; imposition of post-market or clinical trials to assess new safety risks; or imposition of distribution or other restrictions. Other potential consequences include, among other things:

•

restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market or product recalls;

•

fines, warning letters or other enforcement-related letters or clinical holds on post-approval clinical trials;

•

refusal of the FDA to approve pending NDAs or supplements to approved NDAs, or suspension or revocation of product approvals;

•

product seizure or detention, or refusal to permit the import or export of products;

•

injunctions or the imposition of civil or criminal penalties; and

•

consent decrees, corporate integrity agreements, debarment, or exclusion from federal health care programs; or mandated modification of promotional materials and labeling and the issuance of corrective information.

Manufacturing

Overall, management believes the manufacturing process established by the prior sponsor of our development program is efficient with cost of goods sold expected to be less than 5% of a preliminary range of proposed sales price estimates.

Thus far, ibezapolstat has been manufactured successfully in both 1 kg and 9 kg batches, with 9 kg batches considered to be a commercial scale. We anticipate that the commercial batch size upon completion of the clinical development program and submission of an NDA will be 10 kg to 15 kg which in our estimation will further reduce our cost of goods sold. The 9kg batch was sufficient to support the Phase 1 and Phase 2 clinical trial needs. No material issues were noted in the manufacture of either the 1 kg or 9 kg batches of ibezapolstat to date with 24-month stability very good and well within acceptable FDA standards. Additionally, ibezapolstat 150mg capsules have been manufactured and used in the Phase 1 and Phase 2a clinical trial with adequate inventory available to cover Phase 2B clinical supply requirements. Twenty-four

TABLE OF CONTENTS

month stability data on capsules show no significant changes in the key quality attributes and no discernable data trends at any of the storage conditions. A minimum of 24-months shelf-life is anticipated.

Through our outside manufacturing vendors, we will continue to monitor the stability of the drug substance (API) and drug product on an ongoing basis as we continue to advance the clinical development program.

Market Opportunity

According to the 2017 Update (published February 2018) of the Clinical Practice Guidelines for Clostridium difficile Infection in Adults and Children by the Infectious Diseases Society of America (IDSA) and Society of Healthcare Epidemiology of America (SHEA), CDI remains a significant medical problem in hospitals, in long-term care facilities and in the community. Clostridioides (formerly Clostridium) difficile, also known as C. difficile or C. diff, is one of the most common causes of health care-associated infections in U.S. hospitals (Lessa, et al, 2015, New England Journal of Medicine). Recent estimates suggest C. difficile approaches 500,000 infections annually in the U.S. and is associated with approximately 20,000 deaths. (Guh, 2020, New England Journal of Medicine). Based on internal estimates including a recurrence rate of between 20% and 40% among approximately 150,000 patients treated, we believe that the annual incidence in the U.S. approaches 600,000 infections and a mortality rate of approximately 9.3%.

Antibiotics provide advantages over the use of antibodies, microbiologics, and vaccines. Antibodies are generally only administered in combination with an antibiotic. Due to high costs and the inability to use antibodies as a first-line treatment, antibodies have gained limited commercial traction and there has only been one antibody treatment for CDI approved to date. As of the date of this prospectus, there are currently two microbiologics in late-stage development with clinical data forthcoming. Safety is a concern with microbiologics, and this course of treatment is only recommended for patients with multiple recurrences of CDI who have failed appropriate antibiotic treatments. There are also several vaccines against C. difficile in late-stage development, but none are currently approved. A vaccine is only likely to be commercially viable as a prevention of recurrent CDI in high-risk patients, if such patients can be identified. Additionally, large numbers of patients are required for clinical trials of vaccines, which could significantly delay the clinical development process for and eventual release of any CDI vaccine products currently in development.

C. difficile has surpassed MRSA, as the leading cause of death among hospitalized patients. CDI is a serious illness resulting from infection of the inner lining of the colon by C. difficile bacteria that produce toxins causing inflammation of the colon, severe diarrhea and, in the most serious cases, death. Patients typically develop CDI from the use of broad-spectrum antibiotics that disrupt normal gastrointestinal (gut) flora, thus allowing C. difficile bacteria to flourish and produce toxins. C. difficile is a spore forming bacterium, creating spores excreted in the environment of the patients that can survive for months on dry surfaces in hospital rooms such as beds and doors, and can contaminate other patients by fecal-oral transmission through the hands of healthcare workers.

We estimate that, if approved, ibezapolstat could capture over 20% of the CDI market in peak year sales based on the incidence rates noted above. At a preliminary price estimate of $3,000 to $3,500 per full course of treatment, this projects out to estimated peak year sales of approximately $500 million. The peak market penetration of 20% assumes that there will be at least three treatment options available to treat CDI in addition to ibezapolstat even though only two antibiotics are currently recommended for the treatment of CDI and only ridinilazole is in late-stage development and may or may not succeed in Phase 3 clinical trials and/or obtain FDA approval. The selling price estimate of $3,000 to $3,500 is considered by management to be conservative as it is well below the price point of fidaxomicin, the most- recent approval in treating CDI.

TABLE OF CONTENTS

Management believes that this market opportunity is substantial and provides significant upside potential for those investing at this early stage of development. We believe the size of the market and relatively few treatment options available will drive our market capitalization and availability of financing alternatives as it completes Phase 2 clinical trials successfully.

In addition, we believe ibezapolstat’s profile provides an opportunity to develop significant market penetration of patients with recurrent infection following use of one of the initial-episode treatment options because of its unique mechanism of action.

Competition

The biopharmaceutical industry is characterized by rapidly advancing technologies, intense competition and a strong emphasis on proprietary products. While we believe that our technologies, knowledge, experience and scientific resources provide us with competitive advantages, we face potential competition from many different sources, including major pharmaceutical, specialty pharmaceutical and biopharmaceutical companies, academic institutions, government agencies and private and public research institutions. Any product candidates that we successfully develop and commercialize will compete with existing therapies and new therapies that may become available in the future.

Many of our competitors may have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved products than we do. These competitors also compete with us in recruiting and retaining qualified scientific advisors and consultants as well as management personnel and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs. Other small or early stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies.

Our commercial opportunity 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 any products that we may develop. Our competitors also may obtain marketing approvals for their products more rapidly than we obtain approval for ours. In addition, our ability to compete in the marketplace may be affected because in some cases insurers or other third-party payors seek to encourage the use of generic products. This may have the effect of making branded products less attractive, from a cost perspective, to buyers.

The key competitive factors affecting the success of our product candidate and other potential product candidates in the future are likely to be their efficacy, safety, convenience, price and the availability of coverage and reimbursement from government and other third-party payors.

The competition for ibezapolstat include the following:

TABLE OF CONTENTS

•

Several pharmaceutical companies have established themselves in the market for the treatment of CDI and several other companies, like Summit Therapeutics, are developing investigational antibiotics for the treatment of CDI. We expect these products, if approved, will compete with ibezapolstat;

•

Current antibiotic treatments for patients with CDI include broad spectrum antibiotics like vancomycin and metronidazole, both of which are available in generic form in the U.S. Generic antibiotics typically are sold at lower prices than branded antibiotics and generally are preferred by managed care providers of health services;

•

Fidaxomicin (Dificid® in the U.S., Dificlir™ in Europe) is approved for the treatment of CDI in the U.S. and Europe. Fidaxomicin was originally developed by Optimer Pharmaceuticals, Inc., which was later acquired by Cubist Pharmaceuticals, Inc. (“Cubist”). Cubist was then acquired by Merck & Co., Inc. (“Merck”);

•

Ridinilazole is a new antibiotic candidate (Summit Therapeutics) and, in January 2020, its sponsor opened enrollment in a Phase 3 clinical trial program for the treatment of CDI with target completion date of September 2021 as posted on clinicaltrials.gov; and

•

A number of other approaches for the treatment of CDI are in development or have been approved as follows:

•

Merck developed a monoclonal antibody, bezlotoxumab, and obtained FDA approval for it in 2016 and EMA approval in 2016. This antibody neutralizes certain toxins that are produced by C. Difficile bacteria and would be an adjunctive therapy to antibiotics.

•

Pfizer is developing PF-06425090, a three-dose recombinant vaccine designed to stimulate an antibody against the two main toxins (A and B) produced by C. difficile which cause the characteristic diarrhea and colitis.

•

Fecal biotherapy aims to recolonize the bacteria that comprise the natural gut flora and, according to the 2017 IDSA Guidelines would be used for patients with multiple recurrences of CDI who have failed to resolve their infection despite treatment attempts with antibiotic agents targeting CDI.

•

Fecal biotherapy approaches in development include SER-109, being developed by Seres Therapeutics, Inc., which is an investigational oral microbiome therapeutic for the prevention of recurrent C. difficile infection in adults with multiply recurrent CDI. The FDA has granted SER-109 both Breakthrough Therapy and Orphan Drug designations and has recently initiated a Phase 3 clinical trial.

•

RBX2660 which is being developed by Rebiotix, Inc. is a microbiome-based technology and is currently being evaluated in a Phase 3 clinical trial for the prevention of recurrent C. difficile infection.

•

CRS3123 (Crestone Inc) is a novel small molecule that selectively inhibits methionyl-tRNA synthetase of C. difficile and is reported on clinicaltrials.gov as recruiting in a Phase 2 clinical trial with a primary completion date of December 2021.

•

MGB-BP-3 (MGB Biopharma) is a novel synthetic polyamide active against Gram- positive pathogens and binds to the minor groove of DNA. MGB announced that it has completed a dose-ranging Phase 2 clinical trial.

•

No new antibiotics in clinical development have shown improvement in either initial clinical cure (“ICR”) or sustained clinical response (“SCR”) in comparison to currently marketed antibiotics. The data in the chart below constitute comparisons of data from prior clinical trials published in scientific journals for each listed antibiotic or antibiotic candidate and does not incorporate data, if any, from any control arm(s) that may be or may have been required to seek and obtain FDA approval. The data listed for ibezapolstat are from the Phase 2a clinical trial where no comparator agent was used. The only comparative data for ibezapolstat in clinical trials currently relate only to comparisons of the impact on the microbiome for ibezapolstat and vancomycin but do not compare clinical cure rates. All data presented is based on identical clinical endpoints used for ICR and SCR.

Competitive Strengths

We attribute our success to the following competitive strengths:

(i)

(ii)

(iii)

(iv)

As of the date of this prospectus, ibezapolstat has shown an excellent human safety profile;

(v)

Our designation by the FDA of Qualified Infectious Disease (QIDP) status and Fast Track designation provides significant benefits to our development of ibezapolstat. We have significant existing patent coverage in the world’s largest pharmaceutical markets (U.S., Europe, Japan and Canada) extending to September 2030 in the United States and September 2030 in foreign markets. There is also the possibility to extend those patents thereafter;

(vi)

We have a simple and low-cost process of manufacturing which is expected to yield cost of goods of less than 5% of the anticipated retail price; and

(vii)

We believe that there is a high probability that the Phase 2b trial will be successful. If the vancomycin cure rate in our Phase 2b trial is 26/32 (81%); then ibezapolstat needs to achieve a cure rate of 24/32 (75%) in the Phase 2b clinical trial to be considered non-inferior (“NI”), to vancomycin based on a “p-value” of .0344. A “p value” is a statistical probability value used by FDA and drug developers to evaluate the efficacy, in this case, of development stage antibiotic candidates and their comparability to one or more approved products. A “p value” of .0344 is within FDA standards used by drug development companies to compare an experimental product candidate, like ibezapolstat, against an existing standard-of-care.

Intellectual Property and Market Exclusivity

We have two U.S. patents (U.S. Patent Numbers 6,926,763 and 8,796,292), with claims that cover ibezapolstat that expire in May 2023 and September 2030, respectively. The most important U.S. patent in

TABLE OF CONTENTS

management’s view, is the composition-of-matter patent (8,796,292) which expires in September 2030. Patent Number 6,926,763 includes claims that cover disubstituted purine compounds, compositions, surface coatings, and methods of treating bacterial infection or inhibiting bacterial growth, and these claims cover ibezapolstat. Patent Number 8,796,292 includes other claims that cover other disubstituted purine compounds, compositions, and methods of inhibiting bacterial growth and these claims cover ibezapolstat. Either patent may be subject to extension subject to certain circumstances.

For ibezapolstat, we also have one composition-of-matter patent in each of Europe, Japan and Canada. All of these non-U.S. patents expire in September 2030, subject to extension under certain circumstances.

We believe the commercial opportunity for ibezapolstat is best protected by regulatory exclusivity in the U.S. that has been made available for new chemical entities (five years) and QIDP designated products (five years).

The FDA has granted QIDP status for the oral use of ibezapolstat to treat CDI. QIDP status is provided by the FDA under the GAIN Act and provides incentives for us as the sponsor of the ibezapolstat development program, including FDA priority review for the first application submitted for the QIDP, eligibility for “fast track” status and extension of statutory exclusivity periods in the U.S. for an additional five years upon FDA approval of ibezapolstat for the treatment of CDI. In January 2019, the FDA approved “fast track” designation for ibezapolstat for the oral treatment of CDI. Accordingly, we will have 10 years of regulatory exclusivity on the oral use of ibezapolstat to treat CDI from the date of FDA marketing approval.

We believe the patent and regulatory coverage already in place provides strong protection for the commercialization of ibezapolstat and we will continue to consider additional patent submissions as we review available pre-clinical and clinical data as it becomes available throughout the development program.

With regard to ACX-375C, we have two issued patents including composition-of-matter, formulation and method-of-use claims to treat Gram-positive bacterial infections (including those resistant to other antibiotics) as well as a third patent application which is currently pending. The two issued patents (U.S. Patent Numbers 10,723,741 and 10,836,772), expire in December 2039 unless extended. We have filed a corresponding international application (“PCT”) that is currently pending and such PCT includes the same composition-of-matter, formulation and method-of-use claims to treat Gram-positive bacterial infections as filed in the U.S. The coverage of this PCT is worldwide subject to our submission of national stage patents in the future replacing the PCT submissions. Management will select the non-U.S. jurisdictions to file the national stage patents in the future based, in part, on the resources available to us at that time. These PCTs, if approved, would expire in December 2039 unless extended.

Management believes that ACX-375C series lead product candidate will be QIDP and Fast-Track eligible as it is a new chemical entity and its antibacterial spectrum of activity covers bacterial pathogens included in the FD&C GAIN Act as “qualifying pathogens” for QIDP status. Accordingly, management anticipates 10 years of regulatory exclusivity from FDA approval to further secure the commercial potential of ACX-375C. We intend to file for QIDP and Fast-Track designations with the FDA at the appropriate time in the drug development process as was done in 2018 with ibezapolstat.

GAIN Exclusivity for Antibiotics

Our regulatory strategy includes targeting QIDP designation by the FDA under the GAIN Act. Congress passed the GAIN Act as part of FDASIA in 2012 to encourage the development of antibacterial and antifungal drug products that treat pathogens that cause serious and life-threatening infections.

Potential External Positive Drivers in 2021 for Sector

PASTEUR Act. The PASTEUR Act is legislation currently in the U.S. congress which, if approved, would provide “pull” incentives in the U.S. for developers of new classes of antibiotics that target a critical need. According to the Pasteur Act, the US Department of Health and Human Services would pay a subscription payment for eligible products of $750 million to $3 billion over a ten-year period and patients

TABLE OF CONTENTS

would receive the drug at no cost. In addition, HHS would provide transitional support to fund Phase 3 clinical trials and manufacturing requirements for certain innovative antimicrobial drugs.

AMR Action Fund. The AMR Action Fund was created by the Antimicrobial Resistance Congress to generate interest to develop new classes of antibiotics to treat priority pathogens on the WHO and CDC priority pathogens list. The AMR Action Fund is funded by over 20 fully integrated worldwide pharmaceutical companies which have pledged over $1 billion to fund clinical activities of up to 15 sponsors of new classes of antibiotics to treat priority pathogens. We have active correspondence with the AMR Action Fund and anticipate initial funding commitments to be funded in 2021.

DISARM Act. The DISARM Act is legislation currently in the U.S. Congress which would remove the financial disincentives now in place for prescribers of antibiotics to use novel agents possibly more efficacious than older, less effective antibiotics that are prescribed at a lower cost. Accordingly, treating physicians would have the opportunity to treat patients with infectious disease with the most effective agents thereby enhancing patient outcomes as well as reducing the cost burden on public health.

EU Pull Incentives. Given the adoption of pull incentives for certain critical antibiotics adopted in the U.K. and under consideration in the U.S., the European Union currently is considering adopting certain pull incentives specifically to incentivize sponsors of key antibiotic development programs in the European Union. The European Union also is considering the creation and funding of a new regulatory organization similar to the Biomedical Advanced Research and Development Authority (“BARDA”), which is a division of the HHS which, among other things, is responsible to protect the U.S. against pandemic threats.

Pipeline Products

A series of novel antibacterial molecules derived from ACX-375C appear to share the same mechanism of action with ibezapolstat, i.e. they inhibit the Pol IIIC enzyme in certain Gram-positive bacterial cells including both sensitive and resistant Clostridium difficile (C. difficile), MRSA, vancomycin resistant Enterococcus, PRSP and other resistant bacteria. Further characterization and testing of these molecules is ongoing.

[MISSING IMAGE: tm2111636d1-ph_produc4clr.jpg]

This diverse series of new agents which are believed to bind Pol IIIC and thereby prevent it from synthesizing new DNA, as shown below, where the gray area is the Pol IIIC enzyme and the therapeutic molecule occupies the critical binding pocket.

Compounds in this series have demonstrated potent activity against clinically important pathogens including minimum inhibitory concentration values, or MIC values, against MRSA, VRE and PRSP of 1 – 4 µg/mL. Further characterization and testing in animal models are ongoing.

To date, we have synthesized >435 novel analogs targeting Pol IIIC, which have been screened for potency (MIC) against a panel of pathogens. The table below shows the number of compounds with strong potency vs. MRSA, VRE, and both MRSA and VRE. These potential lead compounds have met the first

TABLE OF CONTENTS

criteria, MIC potency ≤4 µg/mL vs. key pathogens. The Lead Optimization goal is to identify and synthesize compounds with this potency while demonstrating improvements in (1) aqueous solubility, (2) plasma protein binding and (3) cytotoxicity.

Number of Pol IIIC inhibitor compounds with potent MICs vs. MRSA and/or VRE:

MIC Range	MRSA	VRE	MRSA and VRE
< 1 µg/mL	18 compounds	51 compounds	17 compounds
>1 to <2 µg/mL	65 compounds	100 compounds	61 compounds
>2 to < 4 µg/mL	74 compounds	80 compounds	21 compounds

Analogs with good MIC are tested for cytotoxicity (CC50; µg/mL) vs. mammalian cell lines Hep G2 (liver) and HEK 293t (kidney), and against primary human hepatocytes. Several compounds show significant reduction of cytotoxicity (CC50 >128 µg/mL for both cell lines) as compared to ACX-375C (CC50 =35 µg/mL). The thermodynamic solubility has been improved for numerous compounds as well.

To date, a number of potential lead compounds have been tested in a lethal systemic MRSA-infection mouse model vs. vancomycin and vehicle control. These data show that some of our novel compounds show superior efficacy vs. low-dose vancomycin, as demonstrated by an increase in survival rate and duration, including one new lead compound dosed orally. Additional preliminary work demonstrated good bactericidal activity for several compounds vs. MRSA and VRE, as well as significant post-antibiotic effect (“PAE”), or the suppression of bacterial growth that persists after brief exposure of organisms to antimicrobials, (PAE >5 hours) vs. VRE, but not vs. MRSA. Early lead compounds show oral bioavailability from 33 – 59% in the absence of any absorption enhancing agents. An MIC screen of a few Acurx compounds vs. recent clinical isolates demonstrates potent activity against daptomycin-, vancomycin- and linezolid resistant strains of MRSA, E. faecalis and E. faecium. Based on the novel MOA for these Pol IIIC inhibitors, we anticipate strong antibacterial activity vs. all currently resistant isolates.

Taken as a whole, the nonclinical microbiology results indicate that our new antimicrobial potential lead product candidates (a) show potent in vitro inhibitory and killing activity against MRSA, vancomycin resistant Enterococcus, PRSP and other resistant bacteria, (b) are likewise effective in protecting and treating animals from induced life-threatening infections, and (c) therefore show promise in being able to treat Gram-positive infections in patients.

These bacterial targets (MRSA, VRE and PRSP) involve an incidence of approximately six million patients per year in the U.S. alone. Based on a review of other antibiotics currently marketed to treat these bacterial infections, our early estimate of peak year sales potential is 4% to 5% of this annual incidence and a peak year sales potential of approximately $1 billion.

Legal Proceedings

From time to time, we may become involved in various lawsuits and legal proceedings, which arise, in the ordinary course of business. We are currently not aware of any legal proceedings or claims that we believe will have a material adverse effect on our business, financial condition or operating results.

He is also a Certified Valuation Analyst (CVA) and is Accredited in Business Valuation (ABV). Mr. Donohue was selected to serve on our board of directors because of his expertise in financial accounting.

Family Relationships

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

Leadership Structure of Our Board of Directors

Our board of directors has responsibility for establishing broad corporate policies and reviewing our overall performance rather than day-to-day operations. The primary responsibility of our board of directors is to oversee our management and, in doing so, serve our best interests and the best interests of our stockholders. Our board of directors selects, evaluates and provides for the succession of executive officers and, subject to stockholder election, directors. It reviews and approves corporate objectives and strategies, and evaluates significant policies and proposed major commitments of corporate resources. Our board of directors also participates in decisions that have a potential major economic impact on us. Management keeps the directors informed of company activity through regular communication, including written reports and presentations at board of directors and committee meetings.

Our officers are appointed by our board of directors and hold office until they resign or are removed from office by the board of directors.

Thomas Harrison, Joseph C. Scodari, Jack H. Dean, Carl V. Sailer and James Donohue qualify as independent directors.

Classified Board of Directors

We have seven directors. On June 23, 2021, prior to the effectiveness of the registration statement of which this prospectus forms a part, we adopted a certificate of incorporation which provides that, upon the consummation of this offering, our board of directors will be divided into three classes with staggered three-year terms. Only one class of directors will be elected at each annual meeting of stockholders, with the other classes continuing for the remainder of their respective three-year terms. Our current directors will be divided among the three classes as follows:

•

the Class I directors will be Carl V. Sailer and Thomas Harrison and their terms will expire at the annual meeting of stockholders to be held in 2022;

•

the Class II directors will be David P. Luci and Jack H. Dean and their terms will expire at the annual meeting of stockholders to be held in 2023; and

•

the Class III directors will be Robert J. DeLuccia, Joseph C. Scodari and James Donohue and their terms will expire at the annual meeting of stockholders to be held in 2024.

Each director’s term will continue until the election and qualification of their successor, or their earlier death, resignation or removal. Any increase or decrease in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of our directors. This classification of our board of directors may have the effect of delaying or preventing changes in control of our company. See the section titled “Description of Capital Stock — Anti-Takeover Provisions — Classified Board of Directors.”

Committees of the Board of Directors

Our board of directors has two standing committees: an audit committee and a compensation committee. Subject to phase-in rules and a limited exception, the rules of Nasdaq and Rule 10A-3 of the Exchange Act require that the audit committee of a listed company be comprised solely of independent directors, and the rules of Nasdaq require that the compensation committee of a listed company be comprised solely of independent directors.

TABLE OF CONTENTS

Audit Committee

Our board of directors established an audit committee of the board of directors. James Donohue (Chair), Joseph C. Scodari and Thomas Harrison serve as members of our audit committee. Under the Nasdaq listing standards and applicable SEC rules, we are required to have at least three members of the audit committee, all of whom must be independent.

Each member of the audit committee is financially literate and our board of directors has determined that qualifies as an “audit committee financial expert” as defined in applicable SEC rules.

TABLE OF CONTENTS

Our audit committee charter details the principal functions of the audit committee, including:

•

the appointment, compensation, retention, replacement, and oversight of the work of the independent auditors and any other independent registered public accounting firm engaged by us;

•

resolving any disagreements between management and the independent auditor regarding financial reporting;

•

pre-approving all audit and permitted non-audit services to be provided by the independent auditors or any other registered public accounting firm engaged by us, and establishing pre-approval policies and procedures;

•

reviewing and discussing with the independent auditors all relationships the auditors have with us in order to evaluate their continued independence;

•

setting clear hiring policies for employees or former employees of the independent auditors;

•

setting clear policies for audit partner rotation in compliance with applicable laws and regulations;

•

seeking information that we require from employees or any of our direct or indirect subsidiaries (each, a “Subsidiary”), all of whom are directed to cooperate with the audit committee’s requests, or external parties;

•

meeting with any of our officers or employees (or officers or employees of any Subsidiary), the independent auditor or outside counsel, as necessary, or request that any such persons meet with any members of, or advisors or consultants to, the audit committee;

•

obtaining and reviewing a report, at least annually, from the independent auditors describing (i) the independent auditor’s internal quality-control procedures and (ii) any material issues raised by the most recent internal quality-control review, or peer review, of the audit firm, or by any inquiry or investigation by governmental or professional authorities within the preceding five years respecting one or more independent audits carried out by the firm and any steps taken to deal with such issues;

•

reviewing and approving any related party transaction required to be disclosed pursuant to Item 404 of Regulation S-K promulgated by the SEC prior to us entering into such transaction;

•

overseeing that management has established and maintained processes to assure compliance by us with applicable laws, regulations and corporate policy; and

•

reviewing with management, the independent auditors, and our legal advisors, as appropriate, any legal, regulatory or compliance matters, including any correspondence with regulators or government agencies and any employee complaints or published reports that raise material issues regarding our financial statements or accounting policies and any significant changes in accounting standards or rules promulgated by the Financial Accounting Standards Board, the SEC or other regulatory authorities.

Compensation Committee

Our board of directors established a compensation committee of the board of directors. Joseph C. Scodari (Chair), Thomas Harrison and Carl V. Sailer serve as members of our compensation committee. Under the Nasdaq listing standards and applicable SEC rules, we are required to have at least two members of the compensation committee, all of whom must be independent. Joseph C. Scodari, Thomas Harrison and Carl V. Sailer are independent.

Our compensation committee charter details the principal functions of the compensation committee, including:

•

discharging the responsibilities of the board of directors relating to compensation of our directors and executive officers;

•

reviewing and approving on an annual basis the corporate goals and objectives relevant to our Chief Executive Officer’s compensation, evaluating our Chief Executive Officer’s performance in light of such goals and objectives and determining and approving the remuneration (if any) of our Chief Executive Officer based on such evaluation;

TABLE OF CONTENTS

•

reviewing and approving on an annual basis the compensation of all of our other officers;

•

reviewing on an annual basis our executive compensation policies and practices;

•

implementing and administering our incentive compensation equity-based remuneration plans;

•

assisting management in complying with our proxy statement and annual report disclosure requirements;

•

periodically review executive supplementary benefits and, as appropriate, our retirement, benefit, and special compensation programs;

•

overseeing the annual process of evaluation of the performance of our management;

•

if required, producing a report on executive compensation to be included in our annual proxy statement; and

•

reviewing and recommending compensation of the directors, including with respect to any equity-based plans.

The compensation committee charter also provides that the compensation committee may, in its sole discretion, retain or obtain the advice of a compensation consultant, legal counsel or other adviser and will be directly responsible for the appointment, compensation and oversight of the work of any such adviser. However, before engaging or receiving advice from a compensation consultant, external legal counsel or any other adviser, the compensation committee will consider the independence of each such adviser, including the factors required by Nasdaq and the SEC.

Director Nominations

We do not have a standing nominating committee. In accordance with Rule 5605(e)(2) of the Nasdaq rules, a majority of the independent directors may recommend a director nominee for selection by the board of directors. The board of directors believes that the independent directors can satisfactorily carry out the responsibility of properly selecting or approving director nominees without the formation of a standing nominating committee. As there is no standing nominating committee, we do not have a nominating committee charter in place.

The board of directors will also consider director candidates recommended for nomination by our stockholders during such times as they are seeking proposed nominees to stand for election at the next annual meeting of stockholders (or, if applicable, a special meeting of stockholders). Our stockholders that wish to nominate a director for election to the board of directors should follow the procedures set forth in our bylaws.

We have not formally established any specific, minimum qualifications that must be met or skills that are necessary for directors to possess. In general, in identifying and evaluating nominees for director, the board of directors considers educational background, diversity of professional experience, knowledge of our business, integrity, professional reputation, independence, wisdom, and the ability to represent the best interests of our stockholders.

Code of Conduct and Ethics

Our board of directors has adopted a code of conduct and ethics and whistle blower policy that applies to all of our employees, officers and directors. The full text of our code of conduct and ethics and whistle blower policy is posted on the investor relations page on our website. We intend to disclose any amendments to our code of business conduct and ethics, or waivers of its requirements, on our website or in filings under the Exchange Act. Our code of conduct and ethics and whistle blower policy also addresses conflicts of interest that may arise between our business and the future business activities of our directors, executive officers or employees.

Board’s Role in Risk Oversight

Effective risk oversight is an important priority of the board of directors. Because risks are considered in virtually every business decision, the board of directors discusses risk throughout the year generally or in

TABLE OF CONTENTS

connection with specific proposed actions. The board of directors’ approach to risk oversight includes understanding the critical risks in our business and strategy, evaluating our risk management processes, allocating responsibilities for risk oversight among the full board of directors, and fostering an appropriate culture of integrity and compliance with legal responsibilities.

TABLE OF CONTENTS

Directors’ Compensation

Since inception, we have not paid any cash compensation to our directors in connection with their service on the board of directors. Upon their initial appointment to the board of directors, each non-employee director received an equity award of Class A membership interests, which vests in equal monthly installments over a three-year period measured from the date of grant, subject to the non-employee director’s continued service as a director.

Upon the consummation of this offering, we will pay cash compensation of $20,000 per year paid on a quarterly basis to members of the board of directors as well as options to purchase 50,000 shares of common stock under our Equity Incentive Plan which would vest ratably on a monthly basis over a 36-month period from the closing of the offering, subject to accelerated vesting upon a Change of Control. In addition, each committee chairman will receive $750 per meeting and each committee member will receive $500 per committee meeting, in each case, for meetings attended by each such committee chairman and/or member.

Director and Officer Indemnification Agreements and Insurance

We have entered into indemnification agreements with each of our directors and executive officers (the “Indemnification Agreements”). Such Indemnification Agreements provide for indemnification against expenses, judgments, fines and penalties actually and reasonably incurred by an indemnitee in connection with threatened, pending or completed actions, suits or other proceedings, subject to certain limitations. The Indemnification Agreements also provide for the advancement of expenses in connection with a proceeding prior to a final, non-appealable judgment or other adjudication, provided that the indemnitee provides an undertaking to repay to us any amounts advanced if the indemnitee is ultimately found not to be entitled to indemnification by us. The Indemnification Agreements set forth procedures for making and responding to requests for indemnification or advancement of expenses, as well as dispute resolution procedures that will apply to any dispute between us and an indemnitee arising under the Indemnification Agreements.

We maintain directors’ and officers’ liability insurance coverage for our directors and officers in their capacities as our directors and officers.

Equity Incentive Plan

Our 2021 Equity Incentive Plan (the “2021 Plan”) was established to attract, retain and motivate our employees, officers, directors, consultants, agents, advisors and independent contractors by providing them with the opportunity to acquire a proprietary interest in us and to align their interests and efforts to the long-term interests of our stockholders. The 2021 Plan provides for, among other things, grants of restricted stock units, stock options, restricted stock and other stock-based awards to employees, directors, consultants and other individuals who provide services to us and our affiliates. As of May 25, 2021, we have 2,000,000 shares of our common stock reserved for issuance under the 2021 Plan. On or about the consummation of this offering, we intend to grant to certain former Class B membership interest holders options to purchase shares of common stock with an exercise price equal to the initial public offering price and with such options to be fully vested on the date of grant.

Eligibility. The 2021 Plan allow for grants, under the direction of the board of directors or compensation committee, as the plan administrator, of stock options, stock appreciation rights, restricted and unrestricted stock awards, restricted stock units and other stock or equity-related cash-based awards to employees, consultants and directors who, in the opinion of the plan administrator, are in a position to make a significant contribution to our long-term success. All of our employees, directors and consultants and our affiliates are eligible to participate in the 2021 Plan.

Shares Available for Issuance. Subject to the provisions of our 2021 Plan, the number of shares available for issuance under the 2021 Plan will be increased on January 2 of each year, beginning on January 2, 2022, and ending on January 2, 2031, in an amount equal to the lesser of (i) 5% of the outstanding shares of our common stock on such date or (ii) such number of shares determined by the plan administrator. Generally, shares of our common stock reserved for awards under the 2021 Plan that lapse or are forfeited will be added back to the share reserve available for future awards. However, shares delivered to or withheld to pay withholding taxes or any applicable exercise price will not be available for issuance under

TABLE OF CONTENTS

the 2021 Plan. In addition, any shares repurchased on the open market using exercise price proceeds will not be available for issuance under the 2021 Plan.

Stock Options. Stock options granted under the 2021 Plan may either be incentive stock options, which are intended to satisfy the requirements of Section 422 of the Code, or non-qualified stock options, which are not intended to meet those requirements. Incentive stock options may be granted to our employees and affiliates, and the aggregate fair market value of a share of our common stock determined at the time of grant with respect to incentive stock options that are exercisable for the first time by a participant during any calendar year may not exceed $100,000. Non-qualified options may be granted to our employees, directors and consultants and our affiliates. The exercise price of a stock option may not be less than 100% of the fair market value of our common stock on the date of grant, and the term of the option may not be longer than ten years. If an incentive stock option is granted to an individual who owns more than 10% of the combined voting power of all classes of our capital stock, the exercise price may not be less than 110% of the fair market value of our common stock on the date of grant and the term of the option may not be longer than five years.

Award agreements for stock options include rules for exercise of the stock options after termination of service. Options may not be exercised unless they are vested, and no option may be exercised after the end of the term set forth in the award agreement. Generally, stock options will be exercisable for three months after termination of service for any reason other than death or total and permanent disability, and for one year after termination of service on account of death or total and permanent disability, but will not be exercisable if the termination of service was due to cause.

Restricted Stock. Restricted stock is common stock that is subject to restrictions, including a prohibition against transfer and a substantial risk of forfeiture, until the end of a “restricted period” during which the grantee must satisfy certain time or performance-based vesting conditions. If the grantee does not satisfy the vesting conditions by the end of the restricted period, the restricted stock is forfeited. During the restricted period, the holder of restricted stock has the rights and privileges of a regular stockholder, except that generally dividend equivalents may accrue but will not be paid during the restricted period, and the restrictions set forth in the applicable award agreement apply. For example, the holder of restricted stock may vote the restricted shares, but he or she may not sell the shares until the restrictions are lifted.

Other Stock-Based Awards and Performance-Based Awards. The 2021 Plan also authorizes the grant of other types of stock-based compensation including, but not limited to stock appreciation rights and unrestricted stock awards. The plan administrator may award such stock-based awards subject to such conditions and restrictions as it may determine. We may grant an award conditioned on satisfaction of certain performance criteria. Such performance-based awards also include performance-based restricted shares and restricted stock units. Any dividends or dividend equivalents payable or credited to a participant with respect to any unvested performance-based award will be subject to the same performance goals as the shares or units underlying the performance-based award.

Plan Administration. In accordance with the terms of the 2021 Plan, the board of directors may authorize the compensation committee to administer the 2021 Plan. The compensation committee may delegate part of its authority and powers under the 2021 Plan to one or more directors and/or officers, but only the compensation committee can make awards to participants who are subject to the reporting and other requirements of Section 16 of the Exchange Act. In accordance with the provisions of the 2021 Plan, the plan administrator determines the terms of awards, including which employees, directors and consultants will be granted awards, the number of shares subject to each award, the vesting provisions of each award, the termination or cancellation provisions applicable to awards, and all other terms and conditions upon which each award may be granted in accordance with the 2021 Plan.

In addition, the plan administrator may, in its discretion, amend any term or condition of an outstanding award provided (i) such term or condition as amended is permitted by the 2021 Plan and does not require stockholder approval under the rules of the Nasdaq Stock Market, and (ii) any such amendment will be made only with the consent of the participant to whom such award was made, if the amendment is adverse to the participant unless such amendment is required by applicable law or necessary to preserve the economic value of such award.

TABLE OF CONTENTS

Stock Dividends and Stock Splits. If our common stock is subdivided or combined into a greater or smaller number of shares or if we issue any shares of common stock as a stock dividend, the number of shares of common stock deliverable upon exercise of an option issued or upon issuance of an award will be appropriately increased or decreased proportionately, and appropriate adjustments will be made in the exercise price per share of stock options or purchase price, if any, and performance goals applicable to performance-based awards, if any, to reflect such subdivision, combination or stock dividend.

Corporate Transactions. Upon a merger or other reorganization event, the board of directors, may, in its sole discretion, take any one or more of the following actions pursuant to the 2021 Plan, as to some or all outstanding awards:

•

provide that all outstanding options will be assumed or substituted by the successor corporation;

•

upon written notice to a participant provide that the participant’s unexercised options will terminate immediately prior to the consummation of such transaction unless exercised by the participant within a specified number of days of such notice;

•

in the event of a merger pursuant to which holders of our common stock will receive a cash payment for each share surrendered in the merger, make or provide for a cash payment to option holder participants equal to the difference between the merger price times the number of shares of our common stock subject to such outstanding options, and the aggregate exercise price of all such outstanding options, in exchange for the termination of such options;

•

with respect to other stock awards, provide that outstanding awards will be assumed or substituted by the successor corporation, become realizable or deliverable, or restrictions applicable to an award will lapse, in whole or in part, prior to or upon the merger or reorganization event;

•

with respect to stock awards, and in lieu of any of the foregoing, provide that, upon consummation of the transaction, each outstanding stock award will be terminated in exchange for payment of an amount equal to the consideration payable upon consummation of such transaction to a holder of the number of shares of our common stock comprising such award (to the extent such stock grant is no longer subject to any forfeiture or repurchase rights then in effect or, at the discretion of the board of directors or an authorized committee, all forfeiture and repurchase rights being waived upon such transaction); and

•

pursuant to the 2021 Plan, upon consummation of a Corporate Transaction, to the extent not assumed or substituted by the successor or cashed out, the outstanding awards will terminate.

Amendment and Termination. The 2021 Plan may be amended by our stockholders. The 2021 Plan may also be amended by the board of directors or the compensation committee, provided that any amendment which is of a scope that requires stockholder approval as required by (i) the rules of the Nasdaq Stock Market or (ii) for any other reason, is subject to obtaining such stockholder approval. However, no such action may adversely affect any rights under any outstanding award without the holder’s consent unless such amendment is required by applicable law or necessary to preserve the economic value of such award.

Duration of Plan. The 2021 Plan will expire by its terms on January 2, 2032.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

In October 2020, we issued and sold to investors in a private placement an aggregate of 705,727 Class A membership interests at a purchase price of $3.25 per Class A membership interest, for aggregate consideration of $2,293,613.

The following table sets forth the aggregate number of common stock acquired by our directors, officers and 5% security holders in the financing transactions described above, assuming such Class A membership interests are converted into shares of common stock and such warrants to purchase Class A membership interests are converted into warrants to purchase shares of common stock following the Corporate Conversion.

Investor Rights Agreement

We have entered into investor rights agreements with the investors who participated in our private placement financings between March 2018 and October 2019, including Messrs. DeLuccia, Luci, Sailer, Scodari, Harrison and Dean. Each such investor rights agreement imposes certain affirmative obligations on us and also grants certain rights to such investors, including certain registration rights with respect to the securities held by them and certain additional rights. See “Description of Capital Stock — Registration Rights” for additional information.

Corporate Conversion

Prior to the IPO, we were operating as a Delaware limited liability company under the name Acurx Pharmaceuticals, LLC. In connection with and subsequent to the IPO, we have converted from a Delaware limited liability company to a Delaware corporation pursuant to a statutory conversion and changed our name to Acurx Pharmaceuticals, Inc. Existing holders at the time of our IPO, including certain 5% security holders, executive officers and directors, of our Class A membership units and Class B membership units, received shares of our common stock as a result of the Corporate Conversion.

Employment Agreements

We have entered into employment agreements with each of our executive officers. See “Executive and Director Compensation — Narrative Disclosure to Summary Compensation Table — Executive Employment Agreements” for a further discussion of these arrangements.

Indemnification Agreements

We have entered into indemnification agreements with each of our directors and executive officers. These agreements, among other things, require us to indemnify each director and executive officer to the fullest extent permitted by Delaware law, including indemnification of expenses such as attorneys’ fees, judgments, fines and settlement amounts incurred by the director or executive officer in any action or proceeding, including any action or proceeding by or in right of us, arising out of the person’s services as a director or executive officer. For further information, see “Executive and Director Compensation — Director and Officer Indemnification Agreements and Insurance.”

Policies and Procedures for Related Party Transactions

Our board of directors has adopted a written related party transaction policy, setting forth the policies and procedures for the review and approval or ratification of related person transactions. This policy covers, with certain exceptions set forth in Item 404 of Regulation S-K under the Securities Act, any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which we were or are to be a participant, where the amount involved exceeds $120,000 in any fiscal year and a related person had, has or will have a direct or indirect material interest, including without limitation, purchases of goods or services by or from the related person or entities in which the related person has a material interest, indebtedness, guarantees of indebtedness and employment by us of a related person. In reviewing and approving any such transactions, our audit committee is tasked to consider all relevant facts and circumstances, including, but not limited to, whether the transaction is on terms comparable to those that could be obtained in an arm’s length transaction and the extent of the related person’s interest in the transaction. All of the transactions described in this section occurred prior to the adoption of this policy.

TABLE OF CONTENTS

PRINCIPAL STOCKHOLDERS

The following table sets forth information as of May 25, 2021 with respect to the beneficial ownership of our common stock, giving pro forma effect to the Corporate Conversion, by:

•

each person, or group of affiliated persons, known by us to beneficially own more than 5% of our outstanding shares of common stock

•

each of our named executive officers;

•

each of our directors; and

•

all of our executive officers and directors as a group.

The number of shares beneficially owned by each stockholder is determined in accordance with the rules issued by the SEC, and the information is not necessarily indicative of beneficial ownership for any other purpose. Under these rules, beneficial ownership includes any shares as to which the individual or entity has sole or shared voting power or investment power, which includes the power to dispose of or to direct the disposition of such security. Except as indicated in the footnotes below, we believe, based on the information furnished to us, that the individuals and entities named in the table below have sole voting and investment power with respect to all shares of common stock beneficially owned by them, subject to any community property laws.

Percentage ownership of our common stock before this offering is based on shares of common stock outstanding as of May 25, 2021, after giving effect to the Corporate Conversion, assuming no exercise of the underwriter’s over-allotment option, no exercise of the Underwriter Warrants and no exercise of outstanding warrants or options. Percentage ownership of our common stock after this offering is based on shares of common stock outstanding as of May 25, 2021, after giving effect to the Corporate Conversion, the accelerated vesting of currently unvested board of director and corporate advisory council membership interests and our issuance of 2,500,000 shares of our common stock in this offering, based upon the assumed initial public offering price of $6.00 per share, the midpoint of the price range set forth on the cover of this prospectus assuming no exercise of the underwriter’s over-allotment option, no exercise of the Underwriter Warrants, and no exercise of outstanding warrants or options. In computing the number of shares beneficially owned by an individual or entity and the percentage ownership of that person, shares of common stock subject to options, warrants or other rights held by such person that are currently exercisable or will become exercisable within 60 days of May 25, 2021 are considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other person. Unless noted otherwise, the address of all listed stockholders is Acurx Pharmaceuticals, LLC, 259 Liberty Avenue, Staten Island, NY 10305.

TABLE OF CONTENTS

DESCRIPTION OF CAPITAL STOCK

The following description summarizes important terms of our capital stock and certain provisions of our certificate of incorporation and bylaws. Copies of these documents will be filed with the SEC as exhibits to our registration statement, of which this prospectus forms a part. The descriptions of our common stock and preferred stock reflect the completion of the Corporate Conversion which occurred on June 23, 2021, prior to the effectiveness of the registration statement of which this prospectus forms a part.

General

Following the closing of this offering, our authorized capital stock will consist of 200,000,000 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 May 25, 2021, after giving effect to the Corporate Conversion, there were 7,041,159 shares of our common stock, held by approximately 342 stockholders of record. No shares of our preferred stock are designated, issued or outstanding.

Common Stock

Voting. The holders of our common stock are entitled to one vote for each share held of record on all matters on which the holders are entitled to vote (or consent to).

Dividends. The holders of our common stock are entitled to receive, ratably, dividends only if, when and as declared by our board of directors out of funds legally available therefor and after provision is made for each class of capital stock having preference over the common stock.

Liquidation Rights. In the event of our liquidation, dissolution or winding-up, the holders of our common stock may be entitled to share, ratably, in all assets remaining available for distribution after payment or provision for payment of all debts and other liabilities and subject to the rights of each class or series of capital stock having preference over, or right to participate with, the common stock.

Preemptive and Similar Rights. The holders of our common stock have no preemptive or similar rights.

Preferred Stock

Under our certificate of incorporation, our board of directors will be authorized to direct us to issue shares of preferred stock in one or more series without stockholder approval. Our board of directors has the discretion to determine the powers, privileges, preferences and relative participating, optional and other special rights, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, of each series of preferred stock.

The purpose of authorizing our board of directors to issue preferred stock and determine its rights and preferences is to eliminate delays associated with a stockholder vote on specific issuances. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions, future financings and other corporate purposes, could have the effect of making it more difficult for a third-party to acquire, or could discourage a third-party from seeking to acquire, a majority of our outstanding voting stock. Upon the closing of this offering, there will be no shares of preferred stock outstanding, and we have no present plans to issue any shares of preferred stock.

Warrants

As of May 25, 2021, warrants for the issuance of 1,437,560 shares of our common stock were outstanding, all of which are exercisable at a weighted average exercise price of $2.88 per share, after taking into effect the anticipated conversion of each warrant to purchase Class A membership interest of Acurx Pharmaceuticals, LLC into warrants to purchase shares of common stock of Acurx Pharmaceuticals, Inc. See “Corporate Conversion.” All of the warrants are exercisable through various dates expiring between March 2028 and October 2030. The exercise price and the number of warrant shares purchasable upon the exercise of

TABLE OF CONTENTS

the warrants are subject to adjustment upon the occurrence of certain events, including stock dividends, stock splits, combinations and reclassifications of our capital stock. The warrants also contain a “cashless exercise” provision. The warrants do not confer upon the holders thereof any voting, dividend or other rights as our stockholders.

Registration Rights

Each of our investors in our previous private placements are party to an Investor Rights Agreement affording them certain “piggy back” registration rights with respect to their Class A membership interests in our company and Class A membership interests underlying warrants held by such investors. This comprises of 1,492,233 shares of our common stock on a post-conversion basis and shares of common stock (on a post-conversion basis) underlying warrants to purchase up to 34,300 shares. Notwithstanding the foregoing, we shall have no obligation to register any such securities after the date upon which such securities may be sold under Rule 144.

We refer to all of such Class A membership interests as “registrable securities.” If at any time when there is not an effective registration statement covering all of the registrable securities, we determine to prepare and file with the SEC a registration statement relating to an offering for our own account or the account of others under the Securities Act of any of our equity securities (other than on Form S-4 or Form S-8), we are required to send to each holder of registrable securities written notice of such determination and, if within seven business days after receipt of such notice, any such holder shall so request in writing (which request shall specify the registrable securities intended to be disposed of by the holder), we will cause the registration under the Securities Act of all registrable securities which we have been so requested to register by the holder; provided, however, that, in connection with any underwritten public offering of our securities, we maintain the right to not register all or any portion of the registrable securities if it is determined, after consultation with the managing underwriter, that such registration would materially and adversely affect such underwritten public offering. We have exercised such rights in connection with this offering and therefore are not including any such shares in the registration statement of which this prospectus forms a part.

Forum Selection

Our Certificate of Incorporation and our Bylaws provide that the Court of Chancery of the State of Delaware is the exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claim against us arising pursuant to the Delaware General Corporation Law, our Certificate of Incorporation or our Bylaws; or any action asserting a claim against us that is governed by the internal affairs doctrine. Notwithstanding the foregoing, the exclusive forum provision does not apply to suits brought to enforce any liability or duty created by the Exchange Act, the Securities Act or any other claim for which the federal courts have exclusive jurisdiction. 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 applicable law, be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. The choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers and other employees.

Anti-Takeover Provisions

Our Certificate of Incorporation and Bylaws contain provisions that may delay, defer or discourage another party from acquiring control of us. We expect that these provisions, which are summarized below, will discourage coercive takeover practices or 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, which we believe may result in an improvement of the terms of any such acquisition in favor of our stockholders. However, they also give our board of directors the power to discourage acquisitions that some stockholders may favor.

Authorized but unissued shares. The authorized but unissued shares of our common stock and our preferred stock are available for future issuance without stockholder approval, subject to the requirements of any national securities exchange on which our common stock is listed, should we so qualify for listing.

TABLE OF CONTENTS

These additional shares may be used for a variety of corporate finance transactions, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock and preferred stock could make more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Elimination of Stockholder Action by Written Consent. Our Certificate of Incorporation eliminates the right of stockholders to act by written consent without a meeting.

Special meetings of stockholders. Our certificate of incorporation and bylaws provide that, except as otherwise required by law or provided by the resolution or resolutions adopted by our board of directors designating the rights, powers and preferences of any series of preferred stock, special meetings of our stockholders may be called only by (a) our board of directors pursuant to a resolution approved by a majority of the total number of our directors that we would have if there were no vacancies or (b) the chair of our board of directors, and any power of our stockholders to call a special meeting is specifically denied.

Advance notice requirements for stockholder proposals and director nominations. Our bylaws provide for an advance notice procedure for stockholder proposals to be brought before an annual meeting of stockholders, including proposed nominations of candidates for election to our board of directors. In order for any matter to be “properly brought” before a meeting, a stockholder must comply with advance notice and duration of ownership requirements and provide us with certain information. Stockholders at an annual meeting may only consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of our board of directors or by a qualified stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has delivered timely written notice in proper form to our secretary of the stockholder’s intention to bring such business before the meeting. These provisions could have the effect of delaying stockholder actions that are favored by the holders of a majority of our outstanding voting securities until the next stockholder meeting.

Amendment of Certificate of Incorporation or Bylaws. The Delaware General Corporation Law (“DGCL”) provides generally that the affirmative vote of a majority of the shares entitled to vote on any matter is required to amend a corporation’s certificate of incorporation, unless a corporation’s certificate of incorporation requires a greater percentage. Our certificate of incorporation provides that certain provisions of our certificate of incorporation (namely, those provisions relating to (i) directors; (ii) limitation of director liability, indemnification and advancement of expenses and renunciation of corporate opportunities; (iii) meetings of stockholders; and (iv) certain amendments to our certificate of incorporation and bylaws) may not be altered, amended or repealed in any respect (including by merger, consolidation or otherwise), nor may any provision inconsistent therewith be adopted, unless such alteration, amendment, repeal or adoption is approved by the affirmative vote of the holders of at least sixty-six and two-thirds percent (662∕3%) of the voting power of all of our then-outstanding shares then entitled to vote generally in an election of directors, voting together as a single class. Our certificate of incorporation and bylaws also provide that approval of stockholders holding sixty-six and two-thirds percent (662∕3%) of the voting power of all of our then-outstanding shares entitled to vote generally in an election of directors, voting together as a single class, is required for stockholders to make, alter, amend, or repeal any provision of our bylaws. Our board of directors retains the right to alter, amend or repeal our bylaws.

Classified Board of Directors. Our certificate of incorporation, upon the consummation of this offering, provides for a classified board of directors consisting of three classes of approximately equal size, each serving staggered three-year terms. Only the directors in one class will be subject to election by a plurality of the votes cast at each annual meeting of stockholders, with the directors in the other classes continuing for the remainder of their respective three-year terms. Stockholders do not have the ability to cumulate votes for the election of directors.

Limitations on Liability and Indemnification of Officers and Directors

Our Certificate of Incorporation and Bylaws provides indemnification for our directors and officers to the fullest extent permitted by the DGCL. We have entered into Indemnification Agreements with each of our directors that may be, in some cases, broader than the specific indemnification provisions contained under the DGCL. In addition, as permitted by the DGCL, our Certificate of Incorporation and Bylaws includes provisions that eliminate the personal liability of our directors for monetary damages resulting from breaches

TABLE OF CONTENTS

of certain fiduciary duties as a director. The effect of this provision is to restrict our rights and the rights of our stockholders in derivative suits to recover monetary damages against a director for breach of fiduciary duties as a director. These provisions may be held not to be enforceable for violations of the federal securities laws of the United States.

Section 203 of the Delaware General Corporation Law

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 such stockholder becomes an interested stockholder, unless the business combination is approved in a prescribed manner. A “business combination” includes, among other things, a merger, asset or stock sale or other transaction resulting in a financial benefit to the interested stockholder. An “interested stockholder” is a person who, together with affiliates and associates, owns, or did own within three years prior to the determination of interested stockholder status, 15% or more of the corporation’s voting stock.

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, the board of directors approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

•

upon consummation of the transaction that 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; or

•

at or after the time the stockholder became interested, the business combination was approved by the board of directors of the corporation 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 that is not owned by the interested stockholder.

A Delaware corporation may “opt out” of these provisions with an express provision in its original certificate of incorporation or an express provision in its amended and restated certificate of incorporation or by-laws resulting from a stockholders’ amendment approved by at least a majority of the outstanding voting shares. We have not opted out of these provisions. As a result, mergers or other takeover or change in control attempts of us may be discouraged or prevented.

Listing

Our common stock will be listed on The Nasdaq Capital Market under the symbol “ACXP.”

Transfer Agent and Registrar

The transfer agent and registrar of our common stock is VStock Transfer, LLC. They are located at 18 Lafayette Place, Woodmere, New York 11598. Their telephone number is (212) 828-8436.

TABLE OF CONTENTS

SHARES ELIGIBLE FOR FUTURE SALE

Prior to this offering, no public market for our common stock existed, and a liquid trading market for our common stock may not develop or be sustained after this offering. Future sales of substantial amounts of our common stock in the public market, including shares issued upon exercise of outstanding stock options, or the anticipation of such sales, could adversely affect prevailing market prices of our common stock from time to time and could impair our ability to raise equity capital in the future. Furthermore, because only a limited number of shares of our common stock will be available for sale shortly after this offering due to certain contractual and legal restrictions on resale described below, sales of substantial amounts of our common stock in the public market after such restrictions lapse, or the anticipation of such sales, could adversely affect the prevailing market price of our common stock and our ability to raise equity capital in the future.

Upon the closing of this offering, based on the number of shares of our common stock outstanding as of May 25, 2021 and after giving effect to the Corporate Conversion, the accelerated vesting of currently unvested board of director and corporate advisory council membership interests, we will have an aggregate of 9,541,159 shares of our common stock outstanding (or 9,916,159 shares of our common stock if the underwriters exercise in full their option to purchase additional shares). Of these shares of our common stock, all of the 2,500,000 shares sold in this offering, based upon the initial public offering price of $6.00 per share (or 2,875,000 shares if the underwriters exercise in full their option to purchase additional shares), will be freely tradable unless purchased by our affiliates. The remaining shares of common stock outstanding after this offering will be restricted as a result of securities laws or lock-up agreements. Following the expiration of the lock-up period, all shares will be eligible for resale, subject to compliance with Rule 144 or Rule 701 of the Securities Act.

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, 2,000,000 shares of common stock that are subject to outstanding stock options, underlying restricted stock awards which have not yet vested or reserved for future issuance under our 2021 Equity 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 and Rule 144 and Rule 701 of the Securities Act.

Rule 144

In general, under Rule 144 as currently in effect, beginning 90 days after the date of this prospectus, a person who is not one of our affiliates and who is not deemed to have been one of our affiliates at any time during the three months preceding a sale and who has beneficially owned shares of our common stock that are deemed restricted securities for at least six months would be entitled after such six-month holding period to sell the common stock held by such person, subject to the continued availability of current public information about us (which current public information requirement is eliminated after a one-year holding period).

Beginning 90 days after the date of this prospectus, a person who is one of our affiliates, or has been an affiliate of ours at any time during the three months preceding a sale, and who has beneficially owned shares of our common stock that are deemed restricted securities for at least six months would be entitled after such six-month holding period to sell his or her securities, provided that he or she sells an amount that does not exceed 1% of the number of shares of our common stock then outstanding (or, if our common stock is listed on a national securities exchange, the average weekly trading volume of the shares during the four calendar weeks preceding the filing of a notice on Form 144 with respect to the sale), subject to the continued availability of current public information about us, compliance with certain manner of sale provisions, and the filing of a Form 144 notice of sale if the sale is for an amount in excess of 5,000 shares or for an aggregate sale price of more than $50,000 in a three-month period.

Upon expiration of the lock-up periods described below, 7,041,159 shares of our common stock will be eligible for sale under Rule 144. We cannot estimate the number of shares of our common stock that our existing stockholders will elect to sell under Rule 144.

TABLE OF CONTENTS

Lock-Up Agreements and Market Stand-off Provisions

We, along with our directors and executive officers and holders of substantially all of our capital stock and securities convertible into our capital stock are subject to lock-up agreements which provide that each lock-up party, for a period of up to 180 days after the date of this prospectus (such period, the “restricted period”), may not, without the prior written consent of the underwriter, (i) offer, pledge, sell, contract to sell, grant, lend or otherwise transfer or dispose of, directly or indirectly, any shares of our common stock or any securities convertible into or exercisable or exchangeable for our common stock, (ii) 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 lock-up securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of the lock-up securities, in cash or otherwise, (iii) make any demand for or exercise any right with respect to the registration of any lock-up securities or (iv) publicly disclose the intention to make any offer, sale, pledge or disposition, or to enter into any transaction, swap, hedge or other arrangement relating to any lock-up securities. In addition, if (i) during the last 17 days of such 180-day period, the Company issues an earnings release or material news or a material event relating to the Company occurs, or (ii) prior to the expiration of such 180-day period, the Company announces that it will release earnings results or becomes aware that material news or a material event will occur during the 16-day period beginning on the last day of such 180-day period, the restrictions imposed by such lock-up agreements will continue to apply until the expiration of the 18-day period beginning on the issuance of such earnings release or the occurrence of such material news or material event, as applicable. The underwriters may, in their sole discretion, at any time without prior notice, release all or any portion of the shares from the restrictions in any such agreement.

The lock-up agreements are subject to specified exceptions. In the case of our directors and executive officers and holders subject to the lock-up restrictions, such restrictions described in the paragraph above do not apply, subject in certain cases to various conditions, to:

(a)

transactions relating to securities acquired in open market transactions after the completion of this offering;

(b)

transfers of securities as a bona fide gift or gifts or for estate planning purposes, by will, other testamentary document or intestacy or to a family member or trust for the benefit of a family member (with “family member” meaning any relationship by blood, marriage or adoption, not more remote than first cousin);

(c)

transfers of securities to a charity or educational institution;

(d)

if such lock-up party, directly or indirectly, controls a corporation, partnership, limited liability company, trust or other business entity, any transfers of securities to any shareholder, partner or member of, or owner of similar equity interests in, such lock-up party, as the case may be;

(e)

if required by the terms of a qualified domestic relations order, divorce settlement, divorce decree, separation agreement or court order;

(f)

transfers to any trust for the direct or indirect benefit of such lock-up party or the immediate family of such lock-up party, or if such lock-up party is a trust, to a trustor or beneficiary of the trust or to the estate of a beneficiary of such trust;

(g)

transfers to a nominee or custodian of a lock-up party or entity to whom a disposition or transfer would be permissible under clauses (b), (d), (e) or (f) above;

(h)

transfers to us from our employee or other service provider upon death, disability or termination of employment or service, in each case, of such employee or other service provider;

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS FOR
NON-U.S. HOLDERS OF COMMON STOCK

The following discussion is a summary of certain material U.S. federal income tax considerations applicable to non-U.S. holders (as defined below) with respect to their ownership and disposition of shares of our common stock issued pursuant to this offering. For purposes of this discussion, a non-U.S. holder means a beneficial owner of our common stock that is for U.S. federal income tax purposes:

•

a non-resident alien individual;

•

a foreign corporation or any other foreign organization taxable as a corporation for U.S. federal income tax purposes; or

•

a foreign estate or trust, the income of which is not subject to U.S. federal income tax on a net income basis.

This discussion is based on current provisions of the U.S. Internal Revenue Code of 1986, as amended, which we refer to as the Code, existing and proposed U.S. Treasury Regulations promulgated thereunder, current administrative rulings and judicial decisions, all as in effect as of the date of this prospectus and, all of which are subject to change or to differing interpretation, possibly with retroactive effect. Any such change or differing interpretation could alter the tax consequences to non-U.S. holders described in this prospectus. There can be no assurance that the Internal Revenue Service, which we refer to as the IRS, will not challenge one or more of the tax consequences described herein. We assume in this discussion that a non-U.S. holder holds shares of our common stock as a capital asset within the meaning of Section 1221 of the Code, which is generally property held for investment.

This discussion does not address all aspects of U.S. federal income taxation that may be relevant to a particular non-U.S. holder in light of that non-U.S. holder’s individual circumstances nor does it address any U.S. state, local or non-U.S. taxes, or the 3.8% Medicare tax on net investment income, or any alternative minimum tax consequences, or U.S. federal gift and estate tax laws, or any other aspect of any U.S. federal tax other than the income tax. This discussion also does not consider any specific facts or circumstances that may apply to a non-U.S. holder and does not address the special tax rules applicable to particular non-U.S. holders, such as:

•

banks, insurance companies;

•

tax-exempt organizations, tax-qualified retirement plans, or governmental organizations;

•

financial institutions;

•

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 constructively own, more than five percent of our common stock (except to the extent specifically set forth below); persons who hold our common stock as a position in a hedging transaction, “straddle,” “conversion transaction,” synthetic security, other integrated investment, or other risk reduction transaction;

•

pass-through entities such as partnerships, S corporations, disregarded entities for federal income tax purposes and limited liability companies (and investors therein);

•

persons for whom our stock constitutes “qualified small business stock” within the meaning of Section 1202 of the Code or as “Section 1244 stock” for purposes of Section 1244 of the Code;

•

persons who do not hold our common stock as a capital asset within the meaning of Section 1221 of the Code (generally, for investment purposes);

•

real estate investment trusts or regulated investment companies;

•

pension plans;

•

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

100

TABLE OF CONTENTS

•

“qualified foreign pension funds,” or entities wholly owned by a “qualified foreign pension fund”;

•

persons that elect to apply Section 1400Z-2 of the Code to gains recognized with respect to shares of our common stock;

•

persons who hold or receive our common stock pursuant to the exercise of any employee stock option or otherwise as compensation; and

•

certain U.S. expatriates, former citizens, or former long-term residents of the United States.

This discussion does not address the tax treatment of partnerships or other entities that are pass-through entities for U.S. federal income tax purposes or persons that hold their common stock through partnerships or other pass-through entities. A partner in a partnership or other pass-through entity that will hold our common stock should consult his, her or its tax advisor regarding the tax consequences of acquiring, holding and disposing of our common stock through a partnership or other pass-through entity, as applicable.

This discussion is for general information only and is not tax advice. Accordingly, all prospective non-U.S. holders of our common stock should consult their tax advisors with respect to the U.S. federal, state, local and non-U.S. tax consequences of the purchase, ownership and disposition of our common stock.

Distributions on Our Common Stock

As indicated in the “Dividend Policy” section of this prospectus, we have never declared or paid cash dividends on any of our capital stock and currently intend to retain all available funds and any future earnings to fund the development and growth of our business.

In the event that we do make distributions, subject to the discussions below under the sections titled “Backup Withholding and Information Reporting” and “Withholding and Information Reporting Requirements — FATCA”, distributions paid on our common stock will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. If a distribution exceeds our current and accumulated earnings and profits, the excess will be treated as a tax-free return of the non-U.S. holder’s investment, up to such holder’s tax basis in the common stock. Any remaining excess will be treated as capital gain, subject to the tax treatment described below in “Gain on Sale or Other Taxable Disposition of Our Common Stock.”

Subject to the discussion in the following two paragraphs in this section, dividends paid to a non-U.S. holder generally will be subject to withholding of U.S. federal income tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty between the United States and such holder’s country of residence.

Dividends that are treated as effectively connected with a trade or business conducted by a non-U.S. holder within the United States and, if an applicable income tax treaty so provides, that are attributable to a permanent establishment or a fixed base maintained by the non-U.S. holder within the United States, are generally exempt from the 30% withholding tax if the non-U.S. holder satisfies applicable certification and disclosure requirements. However, such U.S. effectively connected income, net of specified deductions and credits, is taxed at the same graduated U.S. federal income tax rates applicable to United States persons (as defined in the Code). Any U.S. effectively connected income received by a non-U.S. holder that is a corporation may also, under certain circumstances, be subject to an additional “branch profits tax” at a 30% rate or such lower rate as may be specified by an applicable income tax treaty between the United States and such holder’s country of residence.

A non-U.S. holder of our common stock who claims the benefit of an applicable income tax treaty between the United States and such holder’s country of residence generally will be required to provide a properly executed IRS Form W-8BEN or W-8BEN-E (or successor form) to the applicable withholding agent and satisfy applicable certification and other requirements. Non-U.S. holders are urged to consult their tax advisors regarding their entitlement to benefits under a relevant income tax treaty. A non-U.S. holder that is eligible for such lower rate of U.S. withholding tax as may be specified under an income tax treaty may obtain a refund or credit of any excess amounts withheld by timely filing a U.S. tax return with the IRS.

TABLE OF CONTENTS

Gain on Sale or Other Taxable Disposition of Our Common Stock

Subject to the discussions below under “Backup Withholding and Information Reporting” and “Withholding and Information Reporting Requirements — FATCA,” a non-U.S. holder generally will not be subject to any U.S. federal income or withholding tax on any gain realized upon such holder’s sale or other taxable disposition of shares of our common stock unless:

•

the gain is effectively connected with the non-U.S. holder’s conduct of a U.S. trade or business and, if an applicable income tax treaty so provides, is attributable to a permanent establishment or a fixed-base maintained by such non-U.S. holder in the United States, in which case the non-U.S. holder generally will be taxed on a net income basis at the graduated U.S. federal income tax rates applicable to United States persons (as defined in the Code) and, if the non-U.S. holder is a foreign corporation, the branch profits tax described above in “Distributions on Our Common Stock” also may apply;

•

the non-U.S. holder is a nonresident alien individual who is present in the United States for a period or periods aggregating 183 days or more in the taxable year of the disposition and certain other conditions are met, in which case the non-U.S. holder will be subject to a 30% tax (or such lower rate as may be specified by an applicable income tax treaty between the United States and such holder’s country of residence) on the net gain derived from the disposition, which may be offset by certain U.S. source capital losses of the non-U.S. holder, if any (even though the individual is not considered a resident of the United States), provided that the non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses; or

•

we are, or have been, at any time during the five-year period preceding such sale or other taxable disposition (or the non-U.S. holder’s holding period, if shorter) a “U.S. real property holding corporation.” Generally, a corporation is a U.S. real property holding corporation only if the fair market value of its U.S. real property interests equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests plus its other assets used or held for use in a trade or business. Even if we become a U.S. real property holding corporation, gain arising from the sale or other taxable disposition by a non-U.S. Holder of our common stock will not be subject to U.S. federal income tax as long as our common stock is regularly traded on an established securities market, as defined by applicable U.S. Treasury Regulations, and the non-U.S. holder holds no more than 5% of our outstanding common stock, directly or indirectly, actually or constructively, during the shorter of the 5-year period ending on the date of the disposition or the period that the non-U.S. holder held our common stock. If the foregoing exception does not apply, then if we are or were to become a U.S. real property holding corporation a purchaser may be required to withhold 15% of the proceeds payable to a non-U.S. Holder from a sale of our common stock and such Non-U.S. Holder generally will be taxed on its net gain derived from the disposition at the graduated U.S. federal income tax rates applicable to United States persons (as defined in the Code). Although there can be no assurance, we do not believe that we are, or have been, a U.S. real property holding corporation, or that we are likely to become one in the future. No assurance can be provided that our common stock will be regularly traded on an established securities market for purposes of the rules described above. Non-U.S. holders should consult their own tax advisors about the consequences that could result if we are, or become, a U.S. real property holding corporation.

Backup Withholding and Information Reporting

We must report annually to the IRS and to each non-U.S. holder the gross amount of the distributions on our common stock paid to such holder and the tax withheld, if any, with respect to such distributions. Non-U.S. holders may have to comply with specific certification procedures to establish that the holder is not a United States person (as defined in the Code) in order to avoid backup withholding at the applicable rate with respect to dividends on our common stock. Dividends paid to non-U.S. holders subject to withholding of U.S. federal income tax, as described above in “Distributions on Our Common Stock,” generally will be exempt from U.S. backup withholding.

Information reporting and backup withholding will generally apply to the proceeds of a disposition of our common stock by a non-U.S. holder effected by or through the U.S. office of any broker, U.S. or foreign,

102

TABLE OF CONTENTS

unless the holder certifies its status as a non-U.S. holder and satisfies certain other requirements, or otherwise establishes an exemption. Generally, information reporting and backup withholding will not apply to a payment of disposition proceeds to a non-U.S. holder where the transaction is effected outside the United States through a non-U.S. office of a broker. However, for information reporting purposes, dispositions effected through a non-U.S. office of a broker with substantial U.S. ownership or operations generally will be treated in a manner similar to dispositions effected through a U.S. office of a broker.

Non-U.S. holders should consult their tax advisors regarding the application of the information reporting and backup withholding rules to them. Copies of information returns may be made available to the tax authorities of the country in which the non-U.S. holder resides or is incorporated under the provisions of a specific treaty or agreement. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to a non-U.S. holder can be refunded or credited against the non-U.S. holder’s U.S. federal income tax liability, if any, provided that an appropriate claim is filed with the IRS in a timely manner.

Withholding and Information Reporting Requirements — FATCA

Provisions of the Code commonly referred to as the Foreign Account Tax Compliance Act (“FATCA”), generally impose a U.S. federal withholding tax at a rate of 30% on payments of dividends on our common stock paid to a foreign entity unless (i) if the foreign entity is a “foreign financial institution,” such foreign entity undertakes certain due diligence, reporting, withholding, and certification obligations, (ii) if the foreign entity is not a “foreign financial institution,” such foreign entity identifies certain of its U.S. investors, if any, or (iii) the foreign entity is otherwise exempt under FATCA. Such withholding may also apply to payments of gross proceeds of sales or other dispositions of our common stock, although under recently proposed U.S. Treasury Regulations (the preamble to which specifies that taxpayers are permitted to rely on such proposed U.S. Treasury Regulations pending finalization), no withholding will apply to such payments of gross proceeds. Under certain circumstances, a non-U.S. holder may be eligible for refunds or credits of this withholding tax. 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 tax advisors regarding the possible implications of this legislation on their investment in our common stock and the entities through which they hold our common stock, including, without limitation, the process and deadlines for meeting the applicable requirements to prevent the imposition of the 30% withholding tax under FATCA.

UNDERWRITING

Alexander Capital, L.P. is acting as the representative of the underwriters of this offering. Subject to the terms and conditions of the underwriting agreement, dated June 24, 2021, between us and the representative of the underwriters, we will agree to sell to the underwriters, and the underwriters will purchase from us, the aggregate amount of shares of our common stock indicated in the table below:

Underwriters	Number of Shares of Common Stock
Alexander Capital, L.P.		2,166,667
Network 1 Financial Securities, Inc.		333,333
Total:		2,500,000

The underwriters intend to purchase all the shares of common stock offered by us other than those covered by the option to purchase additional shares described below, if they purchase any shares. The obligations of the underwriters may be terminated upon the occurrence of certain events specified in the underwriting agreement. Furthermore, pursuant to the underwriting agreement, the underwriters’ obligations are subject to customary conditions, representations and warranties contained in the underwriting agreement, such as receipt by the underwriters of officers’ certificates and legal opinions.

We have agreed to indemnify the underwriters against specified liabilities, including liabilities under the Securities Act, and to contribute to payments the underwriters may be required to make in respect thereof.

The underwriters are offering the shares, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by its counsel and other conditions specified in the underwriting agreement. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Over-allotment Option

Pursuant to the underwriting agreement, we granted the underwriters an over-allotment option. This option, which is exercisable for up to 45 days after the date of this prospectus, permits the underwriters to purchase a maximum of 375,000 additional shares (15% of the shares sold in this offering) from us to cover over-allotments, if any. If the underwriters exercise all or part of this option, they will purchase shares covered by the option at the public offering price per share that appears on the cover page of this prospectus, less the underwriting discount. If this option is exercised in full, the total net proceeds, before expenses, to us will be $15,870,000.

Discount

The following table shows the public offering price, underwriting discount and proceeds, before expenses, to us. The information assumes either no exercise or full exercise by the underwriters of the over-allotment option.

	Per Share			Total Without Over- Allotment Option		Total With Over- Allotment Option
Public offering price		$	6.00		15,000,000		17,250,000
Underwriting discount (8%)		$	0.48		1,200,000		1,380,000
Proceeds, before expenses, to us		$	5.52		13,800,000		15,870,000

The underwriters propose to offer the shares offered by us to the public at the public offering price per share set forth on the cover of this prospectus. In addition, the underwriters may offer some of the shares to other securities dealers at such price less a concession of $0.24 per share. If all of the shares offered by us are not sold at the public offering price per share, the underwriters may change the offering price per share and other selling terms by means of a supplement to this prospectus.

104

TABLE OF CONTENTS

We will pay the out-of-pocket accountable expenses of the underwriters in connection with this offering.

The underwriting agreement, however, provides that in the event the offering is terminated, any advance expense deposits paid to the underwriters will be returned to the extent that offering expenses are not actually incurred in accordance with Financial Industry Regulation Authority (“FINRA”) Rule 5110(e).

We have agreed to pay the underwriters a non-accountable expenses allowance equal to 1% of the public offering price of the shares (excluding shares that we may sell to the underwriters to cover over-allotments), less the Advance (as defined below). We have also agreed to pay the underwriters’ expenses relating to the offering, including (a) all filing fees incurred in clearing this offering with FINRA and listing our shares of common stock on the Nasdaq Capital Market; (b) fees, expenses and disbursements relating to background checks of our officers and directors; (c) all fees, expenses and disbursements relating to the registration, qualification or exemption of securities offered under the “blue sky” securities laws and other applicable securities laws of all states and domestic and foreign jurisdictions designated by the underwriters; (d) stock transfer and/or stamp taxes, if any, payable upon the transfer of shares of our common stock to the underwriters; (e) the costs associated with printing, mailing and delivering bound volumes of the public offering materials, any common stock certificates as well as Lucite cube mementos and other mementos associated with this offering; (f) the cost associated with the underwriters’ use of book-building and compliance software for the offering, (g) the underwriters’ actual accountable road show expenses for the offering; and (h) up to $75,000 for the fees of the underwriters’ counsel; provided, the maximum amount we have agreed to pay the underwriters for items (b), (e), (f), (g) and (h) above is $150,000. We have paid an expense deposit of $25,000 (the “Advance”), to the representative of the underwriters, which will be applied against the out-of-pocket accountable expenses that will be payable by us to the underwriters in connection with this offering. Any portion of the Advance will be returned to us in the event it is not actually incurred.

We estimate that the total expenses of the offering payable by us, excluding underwriting discounts and commissions, will be approximately $1,100,715.

Discretionary Accounts

The underwriters do not intend to confirm sales of the securities offered hereby to any accounts over which they have discretionary authority.

Underwriter Warrants

We have agreed to issue to Alexander Capital, L.P. warrants to purchase up to an aggregate of 6% of the shares of common stock sold in this offering (excluding the shares sold through the exercise of the over-allotment option) (the “Underwriter Warrants”). The Underwriter Warrants are exercisable 180 days after the effective date of the registration statement of which this prospectus forms a part at $7.50 per share (125% of the public offering price), but may not be transferred at any time prior to the date which is 180 days beginning on the date of commencement of sales of securities in connection with this offering and expiring on a date which is no more than five (5) years from the effective date of the offering in compliance with FINRA Rule 5110(e)(1)(A). The Underwriter Warrants have been deemed compensation by FINRA and are therefore subject to a 180-day lock-up pursuant to FINRA Rule 5110(e). Alexander Capital, L.P. (or its respective permitted assignees under Rule 5110(e)(2)(B)) will not sell, transfer, assign, pledge, or hypothecate the Underwriter Warrants or the securities underlying such warrants, nor will they engage in any hedging, short sale, derivative, put, or call transaction that would result in the effective economic disposition of such warrants or the underlying securities for a period of 180 days following the date of commencement of sales pursuant to the offering. In addition, the Underwriter Warrants provide for “piggy-back” registration rights with respect to the shares underlying such warrants, exercisable in certain cases for a period of no more than seven (7) years from the effective date of the offering in compliance with FINRA Rule 5110(g)(8)(D). We will bear all fees and expenses attendant to registering the securities issuable on exercise of the Underwriter Warrants other than underwriting commissions incurred and payable by the holders thereof. The exercise price and number of shares issuable upon exercise of the Underwriter Warrants may be adjusted in certain circumstances including in the event of a stock dividend, extraordinary cash dividend or our recapitalization, reorganization, merger or consolidation. However, the exercise price of the

105

TABLE OF CONTENTS

Underwriter Warrants or the underlying shares of such warrants will not be adjusted for issuances of shares of common stock at a price below such warrants’ exercise price.

Electronic Offer, Sale and Distribution of Shares

A prospectus in electronic format may be made available on the websites maintained by the underwriters, if any, participating in this offering and the underwriters participating in this offering may distribute prospectuses electronically. The underwriters may agree to allocate a number of shares for sale to its online brokerage account holders. Internet distributions will be allocated by the underwriters that will make internet distributions on the same basis as other allocations. Other than the prospectus in electronic format, the information on these websites is not part of, nor incorporated by reference into, this prospectus or the Registration Statement of which this prospectus forms a part, has not been approved or endorsed by us or the underwriters in their respective capacities as underwriters, and should not be relied upon by investors.

Stabilization

In connection with this offering, the underwriters may engage in stabilizing transactions, over-allotment transactions, syndicate-covering transactions, penalty bids and purchases to cover positions created by short sales.

•

Stabilizing transactions permit bids to purchase shares so long as the stabilizing bids do not exceed a specified maximum and are engaged in for the purpose of preventing or retarding a decline in the market price of the shares while the offering is in progress.

•

Over-allotment transactions involve sales by the underwriters of shares in excess of the number of shares the underwriters are obligated to purchase. This creates a syndicate short position which may be either a covered short position or a naked short position. In a covered short position, the number of shares over-allotted by the underwriters are not greater than the number of shares that they may purchase in the over-allotment option. In a naked short position, the number of shares involved is greater than the number of shares in the over-allotment option. The underwriters may close out any short position by exercising their over-allotment option and/or purchasing shares in the open market.

•

Syndicate covering transactions involve purchases of shares in the open market after the distribution has been completed in order to cover syndicate short positions. In determining the source of shares to close out the short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared with the price at which they may purchase shares through exercise of the over- allotment option. If the underwriters sell more shares than could be covered by exercise of the over-allotment option and, therefore, have a naked short position, the position can be closed out only by buying shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that after pricing there could be downward pressure on the price of the shares in the open market that could adversely affect investors who purchase in the offering.

•

Penalty bids permits the underwriters to reclaim a selling concession from a syndicate member when the shares originally sold by that syndicate member are purchased in stabilizing or syndicate covering transactions to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our shares of common stock or preventing or retarding a decline in the market price of our shares of common stock. As a result, the price of our common stock or warrants in the open market may be higher than it would otherwise be in the absence of these transactions. Neither we nor the underwriters make any representation or prediction as to the effect that the transactions described above may have on the price of our common stock. These transactions may be effected on the Nasdaq Capital Market, in the over-the-counter market or otherwise and, if commenced, may be discontinued at any time.

Passive Market Making

In connection with this offering, the underwriters may engage in passive market making transactions in our common stock on the Nasdaq Capital Market in accordance with Rule 103 of Regulation M under the

106

TABLE OF CONTENTS

Exchange Act, during a period before the commencement of offers or sales of the shares and extending through the completion of the distribution. A passive market maker must display its bid at a price not in excess of the highest independent bid of that security. However, if all independent bids are lowered below the passive market maker’s bid, then that bid must then be lowered when specified purchase limits are exceeded.

Other Relationships

The underwriters and their respective affiliates may, in the future provide various investment banking, commercial banking and other financial services for us and our affiliates for which they have received, and may in the future receive, customary fees. However, except as disclosed in this prospectus, we have no present arrangements with the underwriters for any further services.

Pricing of the Offering

Prior to this offering, there has been no public market for our common stock. The initial public offering price was determined by negotiations between us and the underwriters. Among the factors considered in determining the initial public offering price were our future prospects and those of our industry in general, our sales, earnings and certain other financial and operating information in recent periods, and the price-earnings ratios, price-sales ratios, market prices of securities, and certain financial and operating information of companies engaged in activities similar to ours.

Offer Restrictions Outside the United States

Other than in the United States, no action has been taken by us or the underwriters that would permit a public offering of the securities offered by this prospectus in any jurisdiction where action for that purpose is required. The securities offered by this prospectus may not be offered or sold, directly or indirectly, nor may this prospectus or any other offering material or advertisements in connection with the offer and sale of any such securities be distributed or published in any jurisdiction, except under circumstances that will result in compliance with the applicable rules and regulations of that jurisdiction.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors
and Members Acurx
Pharmaceuticals, LLC

Opinion on the Financial Statements

We have audited the accompanying balance sheets of Acurx Pharmaceuticals, LLC (the “Company”) as of December 31, 2020 and 2019, and the related statements of operations, changes in members’ equity, and cash flows for the years then ended, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019 and the results of its operations and its cash flows for 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 financial statements have been prepared assuming that the Company will continue as a going concern. As further discussed in Note 1 to the accompanying financial statements, the Company has experienced net losses and negative cash flows from operations since inception 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 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s 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 financial statements are free from material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, 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 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 2018.

NOTES TO THE FINANCIAL STATEMENTS

NOTE 1 — NATURE OF OPERATIONS

Business:

Acurx Pharmaceuticals, LLC (the “Company”) is a privately held clinical stage biopharmaceutical company formed in July 2017, with operations commencing in February 2018. The Company is focused on developing new antibiotics that address difficult to treat bacterial infections. The Company’s approach is to develop antibiotic candidates that could potentially block an entirely new molecular target, the DNA polymerase IIIC (Pol IIIC) enzyme, and its research and development pipeline includes early stage Pol IIIC antibiotic candidates that target other Gram-positive bacteria that are active parenterally, and potentially orally, including Methicillin-Resistant Staphylococcus aureus (“MRSA”), Vancomycin-Resistant Enterococcus (“VRE”) and Penicillin-Resistant Streptococcus pneumoniae (“PRSP”). The Pol IIIC enzyme is the primary catalyst for the replication of DNA in certain Gram-positive bacterial cells.

In March 2020, the World Health Organization declared the outbreak of COVID-19, a novel strain of coronavirus, a global pandemic. This outbreak is causing major disruptions to businesses and markets worldwide as the virus spreads. The COVID-19 pandemic has disrupted, and the Company expects it will continue to disrupt, its operations. The extent of the effect on the Company’s operational and financial performance will depend on future developments, including the duration, spread and intensity of the pandemic, and governmental, regulatory and private sector responses, all of which are uncertain and difficult to predict. Although the Company is unable to estimate the financial effect of the pandemic, at this time, if the pandemic continues over a long period of time, it could have a material adverse effect on the Company’s business, results of operations, financial condition, and cash flows. The financial statements do not reflect any adjustments as a result of the pandemic.

In February 2018, the Company purchased the active pharmaceutical ingredient, the intellectual property and other rights to an antibiotic product candidate known as GLS362E (renamed to ACX-362E and now approved for non-proprietary name, ibezapolstat) (the “Asset”) from GLSynthesis, Inc. The Company paid $110,174 in cash, along with granting 100,000 Class B Membership Interests, profits interests as defined in the operating agreement with an exercise price of $0.10 and which would convert to common stock upon a corporate conversion, for all of the interests in and to the Asset. The Company is also required to make various payments totaling $700,000 in aggregate if certain milestones are achieved, which includes $500,000 following the successful completion of two Phase 3 trials (the “Milestones”). The Company is also obligated to make royalty payments equal to 4% of net sales for a period of time equal to the last to expire of any applicable patents, as defined in the purchase agreement. In December 2018, the Company paid $50,000 to GL Synthesis, Inc. upon successfully achieving the first two Milestones. The purchase of the Asset has resulted in our lead antibiotic product candidate, ibezapolstat, which targets the treatment of Clostridium difficile Infections (“CDI”).

The Company’s primary activities since inception have been organizational activities, including recruiting personnel, acquiring rights to a pharmaceutical compound, performing business and financial planning, performing research and development activities relating to the development of its two antibiotic candidates and raising funds through issuances of Class A Membership Interests and warrants to purchase Class A Membership Interests. The Company has not generated any revenues since inception.

The Company has experienced net losses and negative cash flows from operations since inception and expects these conditions to continue for the foreseeable future. The Company has needed to raise capital from sales of its securities to sustain operations. During 2020, the Company raised approximately $4.4 million through two separate private offerings with three respective closings, and has raised $12.9 million in equity offerings since inception starting with investment by the co-founders. As of December 31, 2020, the Company had a cash balance of approximately $3.2 million. Management believes that the Company will continue to incur losses for the foreseeable future and will need additional resources to sustain its operations until it can achieve profitability and positive cash flows, if ever. Management plans to seek additional equity financing and grant funding, but cannot assure that such financing and funding will be available at acceptable terms, or

at all. These matters raise substantial doubt about the Company’s ability to continue as a going concern. The accompanying financial statements do not include any adjustments that might result from the outcome of this uncertainty.

There can be no assurance that the Company’s research and development will be successfully completed or that any Company product candidate will be approved by the Food and Drug Administration (“FDA”) or any other worldwide regulatory authority or become commercially viable. The Company is subject to risks common to companies in the biopharmaceutical industry including, but not limited to, dependence on collaborative arrangements, development by the Company or its competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, and compliance with FDA and other governmental regulations and approval requirements.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

Federal Income Taxes

The Company is organized as a limited liability company, and is not a tax paying entity for Federal and state income tax purposes and, therefore, no income tax expense has been recorded in the financial statements. Income or losses of the Company are passed through to members for inclusion in their respective income tax returns.

Concentration of Credit Risk

The Company maintains its cash balance in one financial institution. The balance is insured up to the maximum allowable by the Federal Deposit Insurance Corporation (“FDIC”). The Company has not experienced any losses in such accounts and does not believe it is exposed to any significant risk of loss on cash. At times, the cash balance may exceed the maximum insured limit of the FDIC.

Guaranteed Payments to Members

Guaranteed payments to members of the Company, that were designated to represent reasonable compensation for services rendered, were accounted for as Company expenses rather than an allocation of the Company’s net income.

Research and Development

In accordance with Accounting Standards Codification Topic No. 730, Accounting for Research and Development Costs, the Company expenses research and development costs when incurred. At times, the Company may make cash advances for future research and development services. These amounts are deferred and expensed in the period the service is provided. The Company incurred net research and development expenses in the amount of $2,202,979 and $3,510,088 for the years ended December 31, 2020 and 2019, respectively.

Share-Based Compensation

The Company accounts for the cost of services performed by officers and directors received in exchange for an award of Company membership interests based on the grant-date fair value of the award. The Company recognizes compensation expense on a straight-line basis over the service period.

F-8

ACURX PHARMACEUTICALS, LLC

NOTES TO THE FINANCIAL STATEMENTS

Share-Based Payments to Vendors

In accordance with the Company’s adoption of ASU No. 2018-07, Compensation — Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, the Company accounts for the cost of services performed by vendors in exchange for an award of Company membership interests based on the grant-date fair value of the award or the fair value of the services rendered; whichever is more readily determinable. Such fair value is measured as of the date the services or the date performance by the other party is complete. The Company recognizes the expense in the same period and in the same manner as if the Company had paid cash for the services.

Foreign Currency Transactions

The financial statements are presented in in U.S. dollars (“USD”) the reporting currency of the Company. The Company may engage in transactions denominated in other foreign currencies. These transactions were translated to USD at rates which approximate those in effect on the transaction dates. Monetary assets and liabilities denominated in foreign currencies at year-end will be translated at exchange rates in effect as of those dates. Nonmonetary assets and liabilities are translated at appropriate historical rates.

Major Vendor

During 2020, the Company had a major vendor that accounted for approximately 40% of the research and development expenditures for the year end December 31, 2020. The same vendor also accounted for approximately 6% of the total accounts payable at December 31, 2020. The Company expects to maintain this relationship with the vendor.

NOTE 3 — ACCOUNTS PAYABLE AND ACCRUED EXPENSES

Accounts payable and accrued expenses at December 31, 2020 and 2019 were as follows:

	2020			2019
Accrued compensation expenses		$	317,068		$	854,244
Accrued research and development			89,156			347,363
Accrued professional fees			49,707			52,680
Other accounts payable and accrued expenses			—			2,304
Total		$	455,931		$	1,256,591

NOTE 4 — PAYCHECK PROTECTION PROGRAM LOAN

In May 2020, the Company received a Paycheck Protection Program (“PPP”) loan under the CARES Act, as administered by the U.S. Small Business Administration (“SBA”) in the amount of $66,503. The Company did not provide any collateral or guarantees in connection with the PPP loan, nor did the Company pay any facility charge to obtain the PPP loan. The note and agreement provides for customary events of default, including those relating to failure to make payment, bankruptcy, breaches of representations and material adverse effects. The Company may prepay the principal of the PPP loan at any time without incurring any prepayment charges. The PPP loan carries an annual interest rate of 0.98% and matures two (2) years from issuance. The Company may apply for loan forgiveness under the PPP loan program within ten months after the covered period, as defined by the CARES Act. The Company will not be obligated to make any payments of principal or interest before the date on which the SBA remits the loan forgiveness amount to the lender or notifies the lender that no loan forgiveness is allowed.

forgiveness has not been formally granted and cannot be guaranteed. If the loan is forgiven in part or in whole, and legal release is received, the Company will reduce the liability by the amount forgiven and record a gain on extinguishment in the statement of operations. However, if loan forgiveness is not granted, the Company estimates approximately, $16,625 may be due in 2021.

NOTE 5 — EXECUTIVE COMPENSATION

The Company’s co-founders and original two executives received compensation pursuant to employment agreements effective commencing January 2018 (the “Original Agreements”). The Original Agreements stipulated that the executives would receive a base salary of $277,000 per annum, of which a portion was payable with the issuance of Class A Membership Interests of the Company at the most recent offering price when the service was rendered. The Company also employs a third executive on a part-time basis for $7,500 per month, of which a portion was payable with the issuance of Class A Membership Interests during 2018. The Company did not issue any Class A Membership Interests to executives in 2019.

In 2019, the three executives executed waiver letters, deferring any unpaid compensation per their Original Agreements until the later to occur of (1) the date upon which the Company has raised $2.5 million from equity/debt offerings and/or grants equal to $2.5 million, and (2) January 15, 2020. Accrued deferred compensation per their Original Agreements was recorded in the amount of $104,000 and $153,664 as of December 31, 2020 and 2019, respectively.

In January 2020, the Company issued 312,680 Class A Membership Interests at $2.50 per unit to its three executives to settle unpaid year-end compensation for 2019 and a year-end bonus award, which was approved by the board of directors.

NOTE 8 — SHARE-BASED PAYMENTS TO VENDORS

The Company granted 147,413 and 161,931 Class A Membership Interests during the years ended December 31, 2020 and 2019, respectively. The fair value of the Class A Membership Interests granted is equal to the value of the most recent private placement, the fair value at grant date. The Company recognizes the expense in the same period and in the same manner as if the Company had paid cash for the services. The Company recorded general and administrative expenses and research and development expenses for vendor equity grants in the amounts of $338,802 and $233,311, and $105,000 and $225,987 during the years ended December 31, 2020 and 2019, respectively.

On October 18, 2019, the Company granted a total of 150,000 restricted Class A Membership Interests to three consultants for investor related consulting services performed in 2019 and for services which are ongoing. These Class A Membership Interests vest on the second anniversary of the grant date, and are subject to accelerated vesting provisions upon a change of control of the Company. The fair value of the Class A Membership Interests granted is equal to the value of the most recent private placement, the fair value at grant date. The Company is recognizing the expense on a straight-line basis over the vesting period. The Company recorded general and administrative expenses in the amounts of $150,000 and $25,000 for the years ended December 31, 2020 and 2019, respectively, with an unrecognized expense of $125,000 at December 31, 2020.

During 2020, the Company issued 10,077 warrants to an investment banker for services relating to the October 2020 private placement. Each warrant vested upon issuance is exercisable for 10 years from the date of issuance and has an exercise price of $3.25 per Class A Membership Interest. The Company used the Black Scholes model to calculate the value of the warrants.

NOTE 9 — PRO FORMA INCOME TAXES AND LOSS PER SHARE (unaudited)

Immediately prior to the effectiveness of the Company’s registration statement on Form S-1, the Company will convert into a Delaware Corporation and will be subject to federal and state income taxes. Accordingly, a pro forma income tax provision has been disclosed as if the Company was a corporation for all periods presented. Based on the Company’s history of generating operating losses and its anticipation of operating losses continuing for the foreseeable future, the Company has determined that it would not have been more likely than not that the tax benefits from these net operating losses would be realized and a full

valuation allowance against all deferred tax assets would be recorded on a pro forma basis. Therefore, for the purposes of the pro forma tax provision, we have applied a 0% combined federal and state income tax rate.

A pro forma net loss per common share has been disclosed for the years ended December 31, 2020 and 2019, assuming that a 2 to 1 conversion ratio will be used to convert the Class A and Class B Membership Interests into shares of common stock at the time of the proposed initial public offering. Pro forma basic net income or loss per common share is computed by dividing net income or loss available to common shareholders by the weighted average number of common shares outstanding during the periods.

NOTE 10 — RELATED PARTY TRANSACTIONS

During 2020, the Company engaged a member of the Board of Directors to provide administrative services for a 12- month period for a total of $15,000. The Company paid and expensed $7,500 for these services for the 12 months ended December 31, 2020, and will expense the balance during 2021 consistent with the terms of the agreement.

NOTE 11 — RECENT ACCOUNTING PRONOUNCEMENTS

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), which requires lessees to recognize on the balance sheet the assets and liabilities for the rights and obligations created by leases with lease terms of more than twelve (12) months. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee will continue to primarily depend on its classification as a finance or operating lease. However, unlike current GAAP, which requires only capital leases to be recognized on the balance sheet, ASU 2016-02 will require both types of leases to be recognized on the balance sheet. ASU 2016-02 also requires disclosures about the amount, timing, and uncertainty of cash flows arising from leases. These disclosures include qualitative and quantitative requirements, providing additional information about the amounts recorded in the financial statements. ASU 2016-02 is effective for fiscal years beginning after December 15, 2021, with early application permitted. We have evaluated the adoption of ASU 2016-02 and determined that the standard will not have an impact on the Company’s financial statements as the Company currently does not have any lease obligations.

NOTE 12 — COMMITMENTS AND CONTINGENCIES

In conjunction with the Asset purchase in February 2018, the Company is required to make various payments related to the ongoing development of ACX-362E totaling $700,000 in aggregate if certain milestones are achieved, which includes $500,000 following the successful completion of two Phase 3 trial Milestones. The Company is also obligated to make royalty payments equal to 4% of net sales of ACX-362E for a period of time equal to the last to expire of any applicable patents, as defined in the purchase agreement. In December 2018, the Company paid $50,000 to GLSynthesis, Inc. upon successfully achieving the first two Milestones, no Milestones were achieved during 2019 and 2020.

NOTE 13 — SUBSEQUENT EVENTS

The Company has evaluated subsequent events from the balance sheet date through April 2, 2021, the date at which the financial statements were available to be issued, and has not identified any requiring disclosure except as noted below:

On January 11, 2021, the Company issued 57,430 Class A Membership Interests to two of its executives to settle unpaid year-end bonus award and deferred compensation, which was approved by the board of directors.

NOTES TO THE CONDENSED INTERIM FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1 — NATURE OF OPERATIONS

Business:

The Company has experienced net losses and negative cash flows from operations since inception and expects these conditions to continue for the foreseeable future. The Company has needed to raise capital from sales of its securities to sustain operations. During 2020, the Company raised approximately $4.4 million through two separate private offerings with three respective closings, and has raised $12.9 million in equity offerings since inception starting with investment by the co-founders. As of March 31, 2021, the Company had a cash balance of approximately $2.6 million. Management believes that the Company will continue to incur losses for the foreseeable future and will need additional resources to sustain its operations until it can achieve profitability and positive cash flows, if ever. Management plans to seek additional equity financing and grant funding, but cannot assure that such financing and funding will be available at acceptable terms,

Such fair value is measured as of the date the services or the date performance by the other party is complete. The Company recognizes the expense in the same period and in the same manner as if the Company had paid cash for the services.

Foreign Currency Transactions

Major Vendor

NOTES TO THE CONDENSED INTERIM FINANCIAL STATEMENTS (UNAUDITED)

Company did not provide any collateral or guarantees in connection with the PPP loan, nor did the Company pay any facility charge to obtain the PPP loan. The note and agreement provides for customary events of default, including those relating to failure to make payment, bankruptcy, breaches of representations and material adverse effects. The Company may prepay the principal of the PPP loan at any time without incurring any prepayment charges. The PPP loan carries an annual interest rate of 0.98% and matures two (2) years from issuance. The Company may apply for loan forgiveness under the PPP loan program within ten months after the covered period, as defined by the CARES Act. The Company will not be obligated to make any payments of principal or interest before the date on which the SBA remits the loan forgiveness amount to the lender or notifies the lender that no loan forgiveness is allowed.

In October 2020, the Company applied for loan forgiveness through their lender and believes that they are in compliance with the PPP regulations allowing for full forgiveness of the loan balance; however, this forgiveness has not been formally granted and cannot be guaranteed. If the loan is forgiven in part or in whole, and legal release is received, the Company will reduce the liability by the amount forgiven and record a gain on extinguishment in the statement of operations. However, if loan forgiveness is not granted, the Company estimates approximately $16,625 may be due in 2021.
