The Company has not generated any revenues from product sales and has historically funded operations primarily from the proceeds of public and private offerings of equity, convertible debt, and convertible preferred stock.

On March 30, 2023, the Company entered into the Merger Agreement with EIP and Merger Sub, pursuant to which, and subject to the satisfaction or waiver of the conditions set forth therein, Merger Sub will be merged with and into EIP at the effective time of the Merger, with EIP continuing after the Merger as the surviving corporation and a wholly-owned subsidiary of the Company. Diffusion has called a special meeting of stockholders currently scheduled for August 15, 2023 in order to obtain the stockholder approvals necessary to complete the Merger and certain related transactions, as more fully described in the Merger Proxy Statement. The Merger is intended to qualify as a tax-free reorganization for U.S. federal income tax purposes. In connection with the Merger Agreement with EIP and efforts to utilize and preserve assets in a manner that maximizes value for its stockholders, the Company committed to a reduction in force in the first quarter of 2023 that impacted seven of the Company’s thirteen employees. The reduction was a cash preservation measure and impacted employees primarily in the Company’s clinical operations function. The Company has paused significant portions of its TSC development activities in the first quarter of 2023, including initiation of the Company’s previously announced Phase 2 study of TSC in newly diagnosed GBM patients.

Substantial additional financing will be required by the Company to continue to fund itsany research and development activities. No assurance can be given that any such financing will be available when needed,activities related to the Company's existing or at all, or thatfuture product candidates, including EIP's product candidates if the Company’s research and development efforts will be successful.

Merger is closed. The Company regularly explores alternative means of financing its operations and seeks funding through various sources, including public and private securities offerings, collaborative arrangements with third parties, and other strategic alliances and business transactions. TheHowever, as of the date of this Quarterly Report, the Company does not have any commitments to obtain additional funds and may no assurance can be unable to obtain sufficient fundinggiven that any such financing will be available in the future — when needed, in sufficient amounts, on acceptable terms, ifor at all. If the Company cannot obtain the necessary funding, it willmay need to, among other things, delay, continue to scale back or eliminate some or all of its research and development programs, modify its overall development strategy for one or enter into collaborations with third parties to commercialize potential products or technologies thatmore product candidates (or the Company as a whole) in a manner it might otherwise seek to develop or commercialize independently; consider other various strategic alternatives, including a merger or sale of the Company;would not if sufficient cash resources were available, or cease operations. If the Company engages in collaborations, it may receive lower consideration upon commercialization of such products than if it had not entered such arrangements or if it entered into such arrangements at later stages in the product development process.operations altogether.

In July 2022, the Company entered into an at-the-market sales agreement (the "2022 Sales Agreement") with BTIG, LLC, ("BTIG") as agent, pursuant to which the Company may sell up to an aggregate of $20.0 million in shares of the Company’s common stock, from time to time through BTIG, by any method permitted that is deemed an “at the market offering” as defined in Rule 415(a)(4) under the Securities Act of 1933, as amended.

Operations of the Company are subject to certain additional risks and uncertainties as well, and any one or more of these factors could materially affect the Company’s financial condition, future operations and liquidity needs. Many of these risks and uncertainties are outside of the Company’s control, including the outcome of its pending merger with EIP and various internal and external factors that willmay affect whether and when the Company’s product candidates become approved drugs and how significant their market share will be, some of which are outsidesuccess or failure of the Company’s control.

Report on Form 10-K.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires the Company 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.

On an ongoing basis, the Company evaluates its estimates using historical experience and other factors, including the current economic environment. Significant items subject to such estimates are assumptions used for purposes of determining stock-based compensation and accounting for research and development activities. Management believes its estimates to be reasonable under the circumstances. Actual results could differ significantly from those estimates.

Fair Value of Financial Instruments

The carrying amounts of the Company’s financial instruments, including cash, cash equivalents, and accounts payable approximate fair value due to the short-term nature of those instruments.

Concentration of Credit Risk

Financial instruments that potentially exposesubject the Company to significant concentrations of credit risk consist principallyprimarily of cash, on deposit with multiplecash equivalents, and marketable securities. The Company maintains deposits in federally insured financial institutions the balancesin excess of which frequently exceed federally insured limits.

The Company has not experienced any losses in such accounts and believes it is not exposed to significant risk on its cash, cash equivalents, and marketable securities.

Cash and Cash Equivalents

The Company considers any highly-liquid investments, such as money market funds, and commercial paper with an original maturity of three months or less to be cash and cash equivalents.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Marketable Securitiessecurities

The Company classifies its marketable securities as available-for-sale, which include commercial paper and U.S. government debt securities with original maturities of greater than three months from date of purchase. The Company considers its marketable securities as available for use in current operations, and therefore classifyclassifies these securities as current assets on the consolidated balance sheet. These securities are carried at fair value, with unrealized gains and losses reported in comprehensive loss and accumulated other comprehensive loss within stockholders’ equity. Gains or losses on marketable securities sold will beare based on the specific identification method.

The Company routinely monitors the difference between cost and the estimated fair value of its investments. Each reporting period, securities with unrealized losses are reviewed to determine whether the decline in fair value requires the recognition of an allowance for credit losses. Factors considered in the review include (i) current market interest rates, (ii) general financial condition of the issuer, (iii) issuers industry and future business prospects, (iv) issuers past defaults in principal and interest payments, and (v) the payment structure of the investment and the issuers ability to make contractual payments on the investment. All of the Company's marketable securities were fully matured at June 30, 2023.

Reverse Stock SplitResearch and Development

On April 18, 2022, Major components of research and development costs include internal research and development (such as salaries and related employee benefits, equity-based compensation, supplies and allocated facility costs) and contracted services (research and development activities performed on the Company’s behalf). Costs incurred for research and development are expensed as incurred.

Upfront payments made to third parties who perform research and development services on the Company’s behalf are expensed as services are rendered.

Patent Costs

Patent costs, including related legal costs, are expensed as incurred and are recorded within general and administrative expenses in the consolidated statements of operations and comprehensive loss.

Stock-based Compensation

The Company filedmeasures stock-based awards at grant-date fair value and records compensation expense on a Certificate of Amendment to its Certificate of Incorporation, as amended, withstraight-line basis over the Secretary of Statevesting period of the Stateaward. The Company uses the Black-Scholes model to value its stock option awards. Estimating the fair value of Delawarestock option awards requires management to implementapply judgment and make estimates, including the Reverse Stock Split at a ratiovolatility of 1-to-50. NaN fractional shares were issued in connection with the Reverse Stock Split. Stockholders who otherwise would have been entitled to receive fractional shares ofCompany’s common stock, became entitled to receive an amount in cash (without interest or deduction) equal to the fractionexpected term of one share to which such stockholder would otherwise be entitled multiplied by $12.93, representing the split-adjusted average closing priceCompany’s stock options, the expected dividend yield and the fair value of the Company’s common stock on the Nasdaq Capital Marketmeasurement date. As a result, if factors change and management uses different assumptions, stock-based compensation expense could be materially different for future awards.

For stock option grants, the five consecutive trading days immediately precedingexpected term was estimated using the effective date“simplified method” for employee options as the Company has limited historical information to develop reasonable expectations about future exercise patterns and post vesting employment termination behavior for its stock option grants. The simplified method is based on the average of the Reverse Stock Split. Proportional adjustments were madevesting tranches and the contractual life of each grant. The Company uses the simplified method to estimate the expected term.

For stock price volatility, the Company uses a combination of its own historical stock price and comparable public companies as a basis for its expected volatility to calculate the fair value of option grants. The Company assumes no dividend yield because dividends are not expected to be paid in the near future, which is consistent with the Company’s outstanding warrants, stock options, and other equity securities, as well as tohistory of not paying dividends. The risk-free interest rate is based on U.S. Treasury notes with a term approximating the reserveexpected term of shares availablethe option.

Net Loss Per Common Share

Basic net loss per share is computed by dividing net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding during each period. Diluted net loss per share includes the effect, if any, from the potential exercise or conversion of securities, such as convertible debt, convertible preferred stock, common stock warrants, stock options and unvested restricted stock that would result in the issuance of incremental shares of common stock. In computing the basic and diluted net loss per share applicable to common stockholders, the weighted average number of shares remains the same for both calculations due to the fact that when a net loss exists, dilutive shares are not included in the calculation as the impact is anti-dilutive.

The following potentially dilutive securities outstanding as of June 30,2022 and 2021 have been excluded from the computation of diluted weighted average shares outstanding, as they would be anti-dilutive:

Recently IssuedAdopted Accounting Pronouncements

In June 2016, the FASB issued ASU 2016-13,2016-13, Financial Instruments—Credit Losses, Measurement of Credit Losses on Financial Instruments (Topic 326)326). The standard amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses for most financial assets and certain other instruments that aren’t measured at fair value through net income. For available-for-sale debt securities, entities will be required to recognize an allowance for credit losses rather than a reduction in carrying value of the asset. Entities will no longer be permitted to consider the length of time that fair value has been less than amortized cost when evaluating when credit losses should be recognized. This newThe Company adopted the guidance is effective for the Companyusing a modified retrospective approach as of January 1, 2023. 2023 which resulted in no cumulative-effect adjustment to retained earnings.

The updated guidance in ASU 2016-13 also amended the previous other-than-temporary impairment (“OTTI”) model for available-for-sale fixed income securities by requiring the recognition of impairments relating to credit losses through an allowance account and limits the amount of credit loss to the difference between a security’s amortized cost basis and its fair value. In addition, the length of time a security has been in an unrealized loss position will no longer impact the determination of whether a credit loss exists.

2023.

Fair value is the price that could be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value determination in accordance with applicable accounting guidance requires that a number of significant judgments be made. Additionally, fair value is used on a nonrecurring basis to evaluate assets for impairment or as required for disclosure purposes by applicable accounting guidance on disclosures about fair value of financial instruments. Depending on the nature of the assets and liabilities, various valuation techniques and assumptions are used when estimating fair value. The carrying amounts of certain of the Company’s financial instruments, including prepaid expense and accounts payable, are shown at cost, which approximates fair value due to the short-term nature of these instruments. The Company follows the provisions of FASB ASC Topic 820, Fair Value Measurement, for financial assets and liabilities measured on a recurring basis. The guidance requires fair value measurements be classified and disclosed in one of the following three categories:

DIFFUSION PHARMACEUTICALS INC.

The following table presents the Company’s assets that are measured at fair value on a recurring basis (amounts in thousands):

The fair values of the Company’s Level 2 marketable securities are estimated primarily based on benchmark yields, reported trades, market-based quotes, issuer spreads, two-sidedtwo-sided markets, benchmark securities, bids, offers, and reference data including market research publications, which represent a market approach. In general, a market approach is utilized if there is readily available and relevant market activity for an individual security.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Legal Proceedings

On August 7, 2014, a complaint was filed in the Superior Court of Los Angeles County, California by Paul Feller, the former Chief Executive Officer of the Company’s legal predecessor under the caption Paul Feller v. RestorGenex Corporation, Pro Sports & Entertainment, Inc., ProElite, Inc. and Stratus Media Group, GmbH (Case No.BC553996) BC553996). The complaint asserts various causes of action, including, among other things, promissory fraud, negligent misrepresentation, breach of contract, breach of employment agreement, breach of the covenant of good faith and fair dealing, violations of the California Labor Code and common counts. The plaintiff is seeking, among other things, compensatory damages in an undetermined amount, punitive damages, accrued interest and an award of attorneys’ fees and costs. On December 30, 2014, the Company filed a petition to compel arbitration and a motion to stay the action. On April 1, 2015, the plaintiff filed a petition in opposition to the Company’s petition to compel arbitration and a motion to stay the action. After a related hearing on April 14, 2015, the court granted the Company’s petition to compel arbitration and a motion to stay the action. On January 8, 2016, the plaintiff filed an arbitration demand with the American Arbitration Association. On November 19, 2018 at an Order to Show Cause Re Dismissal Hearing, the court found sufficient grounds not to dismiss the case and an arbitration hearing was scheduled, originally for November 2020 but later postponed due to the COVID-19COVID-19 pandemic and related restrictions on gatherings in the State of California. In addition, following the November 2018 hearing, an automatic stay was placed on the arbitration in connection with the plaintiff filing for personal bankruptcy protection. On October 22, 2021, following a determination by the bankruptcy trustee not to pursue the claims and release them back to the plaintiff, the parties entered into a stipulation to abandon arbitration and return the matter to state court. A case management conference was held on February 23, 2022 at which aan initial trial date of May 24, 2023 was set, and the parties have agreed to stipulate to mediation in advance of the trial. On October 20, 2022, the parties filed a joint stipulation to continue the trial and certain deadlines related to the mediation in order to allow plaintiff's counsel to continue to seek treatment for an ongoing medical issue. On November 1, 2022, based on the parties joint stipulation, the court entered an order continuing the trial date to October 25, 2023.

The Company believes the claims in this matter are without merit and intends to defendis defending itself vigorously. However, at this stage, the Company is unable to predict the outcome and possible loss or range of loss, if any, associated with its resolution or any potential effect the matter may have on the Company’s financial position. Depending on the outcome or resolution of this matter, it could have a material effect on the Company’s consolidated financial position, results of operations and cash flows.

Following announcement of the Merger Agreement with EIP and the initial filing on May 11, 2023 of the Company’s Registration Statement on Form S-4 (File No. 333-271823) (the “Registration Statement”), two lawsuits were filed in the United States District Court for the Southern District of New York on May 15, 2023 and May 17, 2023, respectively, by purported stockholders of the Company in connection with the Merger. The lawsuits are captioned Dunlea v. Diffusion Pharmaceuticals, Inc., et al., No. 1:23-cv-04043 (S.D.N.Y.) and Pikazin v. Diffusion Pharmaceuticals, Inc., et al., No. 1:23-cv-04096 (S.D.N.Y.).  Additional stockholder litigations were subsequently filed in the United States District Courts for the Southern District of New York and the District of Delaware and in the Delaware Court of Chancery (collectively with the first two cases, the “Actions”). The complaints in each of the Actions named as defendants the Company and the members of the Company’s board of directors as of such dates. Each of the federal court complaints alleges claims for violations of Section 14(a) of the Exchange Act and Rule 14a-9 promulgated thereunder against all defendants, and violations of Section 20(a) of the Exchange Act against such members of the Company’s board of directors. The Chancery Court complaint, filed after the stockholder had received copies of certain documents in response to a books and records demand under Section 220 of the Delaware General Corporation Law, alleges a claim for breach of fiduciary duty.  The plaintiff in the Chancery Court action also sought expedited treatment and a preliminary injunction barring the scheduled stockholder vote, but those motions were subsequently withdrawn.  The plaintiffs in each of the Actions contend that Registration Statement omitted or misrepresented material information regarding the proposed Merger, rendering the Registration Statement materially misleading. The Actions seek injunctive and declaratory relief, as well as damages.  The Company has also received correspondence from law firms claiming to represent other purported stockholders making similar demands for additional disclosures relating to the Merger. 

The Company believes that the claims asserted in the Actions and the demand letters are without merit.

Stockholders may serve additional demands and/or file additional lawsuits challenging the Merger, which may name the Company, EIP, members of the Company’s board of directors, members of the EIP board of directors and/or others as defendants. No assurance can be made as to the outcome of such additional demands, lawsuits, demand letters or the Actions, including the amount of costs associated with defending, settling, or any other liabilities that may be incurred in connection with the litigation or settlement of, such claims. If any additional demands are served and/or any additional lawsuits filed, absent new or different allegations that are material, the Company will not necessarily announce such additional demands and/or complaints, except as required by applicable law including the rules and regulations of the SEC.

Overview

Diffusion Pharmaceuticals: Enhancing Oxygen, Fueling Life

We areis a biopharmaceutical company that has historically focused on developing novel therapies tothat may enhance the body’s ability to deliver oxygen to the areas where it is needed most. Our leadDiffusion’s most advanced product candidate, TSC, is beinghas been investigated and developed to enhance the diffusion of oxygen to tissues with low oxygen levels, also known as hypoxia, a serious complication of many of medicine’s most intractable and difficult-to-treat conditions, including hypoxic solid tumors.

Business Update

Altitude Trial

During the second quarter, we reported positive effects from our second Oxygenation Trial, the Altitude Trial. This was a double-blind, randomized, placebo-controlled crossover dose exploration study designed to investigate TSC’s effects on oxygen enhancement using an experimental model to induce hypoxia in study participants. The primary endpoints measured in this study were maximal oxygen consumption and partial pressure of arterial blood oxygen in normal healthy volunteers subjected to incremental levels of physical exertion while exposed to hypoxic and hypobaric conditions at a simulated altitude of 15,000 feet above sea level. The secondary endpoints were to assess the effect of TSC on SpO2 and lactate.

A total of 30 healthy volunteers were enrolled in the trial with each subject serving as their own control by completing the experiment twice in a random, blinded order in the same day with a 3-hour rest and wash out period between experimental intervals. During one ascent, study subjects received IV placebo administration and the other ascent the same subject received a single IV dose of TSC at one of three dose levels (0.5 mg/kg, 1.5 mg/kg, or 2.5 mg/kg).

In the trial, following exercise under hypoxic conditions, an increase in pH and a decrease in lactate were observed in the study subjects treated with the highest dose of TSC (2.5 mg/kg), both at the end of the exercise period and at 10 minutes post-exercise relative to placebo. These data suggest the 2.5 mg/kg dose of TSC decreased blood acidity (i.e., lactic acid accumulation) and enhanced metabolic recovery at 10 minutes after completion of exercise under the stressful conditions of simulated high altitude and exercise. These positive changes observed in blood markers of oxygen utilization results in the Altitude Trial suggest TSC may enhance oxygen availability at the cellular level and reinforce our belief in the therapeutic potential of TSC.

Phase 2 Trial in Patients with GBM Incorporating Innovative Imaging Methodology (Study 200-208)

        Taken together, the combination of positive effects observed in each of the TCOM, Altitude, and COVID-19 Trials affirmed our belief in TSC's potentialrecently as an adjuvant treatment to standard of care therapy for GBM and other hypoxic solid tumors. As such,

Pending Merger with EIP Pharma, Inc

Following an extensive process of evaluating strategic alternatives, on July 26, 2022,March 30, 2023, we announced that we had alignedentered into the Merger Agreement with the FDA on the design of an open-label, dose-escalation, Phase 2 safetyEIP and efficacy study of TSC administered with standard of careMerger Sub pursuant to newly diagnosed GBM patients. This trial has been designated Study "200-208,"which, among other things, and we currently expect to initiate the trial by the end of 2022 and to dose the first patient in the study in the first quarter of 2023, subject to the outcomesatisfaction or waiver of the conditions set forth therein, Merger Sub will merge with and into EIP, with EIP continuing as our wholly-owned subsidiary. In connection with the Merger and as more fully described in the Merger Proxy Statement, at a special meeting of stockholders currently scheduled for August 15, 2023, we are seeking approval of our ongoing business development processes described below.stockholders to, among other things, (a) issue the shares of our common stock issuable to former EIP equity holders in connection with the Merger in accordance with the rules of Nasdaq and (b) amend our certificate of incorporation to effect a reverse stock split of the outstanding shares of our common stock at a ratio of not less than 1-for-1.5 and not more than 1-for-8, if necessary to satisfy applicable Nasdaq listing requirements (clauses (a) and (b), collectively, the “Diffusion Special Meeting Proposals”). Our board of directors unanimously approved the Merger Agreement and unanimously recommended that our stockholders approve the Diffusion Special Meeting Proposals.

GBMIf our stockholders approve the Diffusion Special Meeting Proposals and the Merger is an aggressive, deadly, and treatment-resistant type of malignant brain tumor, affecting approximately 13,000 newly diagnosed patients each year incompleted, at or following the United States. Few treatment options are available for patients with GBM, and none have extended life expectancy beyond a few months. In fact, according to the National Brain Tumor Society, the five-year survival rate for GBM is only 6.8 percent with an average survivaleffective time of eight months.

Study 200-208 will include a dose-escalation phase, enrolling patients in a 3+3+3 design, to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of TSC at doses of 1.5 mg/kg, 2.0 mg/kg and 2.5 mg/kg administered in combination with concomitant standard of care radiotherapy plus temozolomide. An additional 17 subjectsMerger, (i) Diffusion will be treated atrenamed “CervoMed Inc.," (ii) subject to satisfying Nasdaq’s initial listing standards, our common stock's ticker symbol on the highest tolerable dose identified inNasdaq Capital Market will change from "DFFN" to “CRVO,” and (iii) the dose escalation phase. The primary objective of the studycombined company will focus on developing EIP’s product candidates for acute and chronic neurodegenerative diseases and other neurologic indications. EIP’s lead drug candidate, neflamapimod, is to evaluate the safety and tolerability of TSCcurrently being developed for the treatment of dementia with Lewy bodies ("DLB"). In the second quarter of 2023, EIP initiated its ongoing, 160-subject Phase 2b clinical trial evaluating neflamapimod in patients with newly diagnosed GBM when administered with standardDLB, the clinical trial costs of care. Secondary objectiveswhich are expected to be fully funded by $21.0 million in non-dilutive grant funding from the National Institutes of Health’s National Institute on Aging awarded to EIP in January 2023. An initial data readout from the study is anticipated in the second half of 2024.

If consummated, immediately following the effective time of the studyMerger, Diffusion stockholders as of immediately before the Merger are expected to evaluate progression-free survivalown approximately 24.68% of the outstanding shares of our common stock and former EIP equity holders as of immediately before the Merger are expected to own approximately 75.32% of the outstanding shares of our common stock, subject to certain assumptions more fully described in the Merger Proxy Statement, including (i) that "Parent Net Cash" (as calculated in accordance with the Merger Agreement) at six monthsthe closing of the Merger is between $13.5 million and $14.5 million and (ii) the exclusion of an estimated 705,571 shares underlying pre-funded warrants that may be issued to former EIP equity holders at the effective time of the Merger in lieu of an equivalent number of shares of our common stock.

As more fully described in the Merger Proxy Statement, consummation of the Merger is subject to certain closing conditions, including, among other things, (a) approval of the Diffusion Special Meeting Proposals by magnetic resonance imaging, assessment using Response Assessmentour stockholders, (b) Nasdaq’s approval of the listing of the shares of our common stock to be issued in Neuro-Oncology criteria,connection with the Merger, and (c) our having Parent Net Cash (as defined in the Merger Agreement) as of closing of the Merger greater than or equal to evaluate overall survival at 12 months.$12.0 million. The Merger Agreement also contains certain termination rights of each of us and EIP which, in certain circumstances, may result in our being required to pay EIP a termination fee of up to $765,000.

Study 200-208 will vary in a varietyAs of ways from the GBM trialsJune 30, 2023, we have conductedhad cash and cash equivalents of approximately $15.0 million. However, as set forth in the past,Merger Agreement and more fully described in the Merger Proxy Statement, the calculation of "Parent Net Cash" involves numerous adjustments to the amount of cash, cash equivalents and marketable securities as reported on our balance sheet and the actual amount of Parent Net Cash delivered at Closing will depend on many factors, including three particularly notable differentiators:

Business Development

Our current strategy for TSC is focused on advancing it through development withamong others, the ultimate objectivedate of obtaining market authorizationsthe closing and entering commercialization, whether alone, with a partner, or through a partner,the magnitude of such adjustments. No assurance can be given as to provide treatment options to patients suffering from life-threatening medical conditions like GBM. We believethe actual amount of Parent Net Cash that will be delivered, that our recent clinical development efforts, includingstockholders will approve the completion of our TCOM and Altitude Trials and our design of Study 200-208, are positive steps for ourDiffusion Special Meeting Proposals, that any other condition to closing will not fail to be satisfied or waived, or that the Merger will be consummated at all. The Company and our stockholders and create the potential to drive meaningful value if we are successful in advancing TSC to the subsequent development milestones we have identified. However, drug development is an extremely expensive, risky, and time-consuming endeavor, particularly so for drugs being developed to treat oncological indications. Accordingly, while we continue our internal efforts to advance the development of TSC, including Study 200-208, we are also taking active steps to identify potential partnership and other opportunities to obtain additional resources for our programs, including opportunities that are non-dilutive to our stockholders.

We also believe we can leverage what we have learned from the development of TSC and the significant skills and experience of our team to opportunistically identify and acquire or in-license novel product candidates that complement our overall strategy and/or are synergistic with our team's core competencies and strengths. We have taken, and intendexpects to continue to take, active steps to identify assets and/or companies for acquisition and/or partnership, as well as a range of other transactions, across a variety of therapeutic indications, that we believe may complement, supplement and/or de-risk our current development programs, as well as provide additional value for our stockholders.

At-The-Market Sales Agreement

In July 2022, we entered intoincur losses following the 2022 Sales Agreement with BTIG, pursuant to which we may sell, from time to time, shares of our common stock having an offering price of up to $20 million in sales deemed to be “at-the-market” equity offerings as defined in Rule 415 of the Securities Act, subject to the offering limits in General Instruction I.B.6 of Form S-3.

As of the dateperiod of this Quarterly Report we have not sold any sharesthrough the closing of common stock pursuantthe Merger (if any) primarily related to the Sales Agreement.proposed Merger and, as a result, available cash, cash equivalents and marketable securities will continue to decrease.
