CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q (“Quarterly Report”) contains forward-looking statements that involve substantial risks and uncertainties. All statements contained in this Quarterly Report other than statements of historical facts, including statements regarding our strategy, future operations, future financial position, future revenue, projected costs, prospects, plans, objectives of management and expected market growth, are forward-looking statements. These statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

The words “anticipate”, “believe”, “estimate”, “expect”, “intend”, “may”, “plan”, “predict”, “project”, “target”, “potential”, “will”, “would”, “could”, “should”, “continue” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. These forward-looking statements include, among other things, statements about:

| ● | our ability to regain and maintain compliance with the continued listing requirements of The Nasdaq Stock Market LLC;

| ● | our ability to satisfy our payment obligations under the First Wave Acquisition (as defined below);

| ● | statements regarding the impact of the COVID-19 pandemic and other geopolitical events, including the wars in Israel and Ukraine and their effects on our operations, access to capital, research and development and clinical trials and potential disruption in the operations and business of third-party vendors, contract research organizations (“CROs”), contract development and manufacturing organizations (“CDMOs”), other service providers, and collaborators with whom we conduct business;

| ● | the loss of key scientific, clinical and nonclinical development, and/or management personnel, internally or from one of our third-party collaborators; and

| ● | other risks and uncertainties, including those listed under Part I, Item 1A., “Risk Factors” in our Annual Report on Form 10-K.

Factors that may cause actual results to differ materially from current expectations include, among other things, those set forth in Part I, Item 1A, “Risk Factors,” of our Annual Report on Form 10-K and for the reasons described elsewhere in this Quarterly Report on Form 10-Q. Any forward-looking statement in this Quarterly Report on Form 10-Q reflects our current view with respect to future events and is subject to these and other risks, uncertainties and assumptions relating to our operations, results of operations, industry and future growth. Given these uncertainties, you should not rely on these forward-looking statements as predictions of future events. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance or achievements. Except as required by law, we assume no obligation to update or revise these forward-looking statements for any reason, even if new information becomes available in the future.

This Quarterly Report on Form 10-Q also contains estimates, projections and other information concerning our industry, our business and the markets for certain drugs and consumer products, including data regarding the estimated size of those markets, their projected growth rates and the incidence of certain medical conditions. Information that is based on estimates, forecasts, projections or similar methodologies is inherently subject to uncertainties and actual events or circumstances may differ materially from events and circumstances reflected in this information. Unless otherwise expressly stated, we obtained these industry, business, market and other data from reports, research surveys, studies and similar data prepared by third parties, industry, medical and general publications, government data and similar sources and we have not independently verified the data from third party sources. In some cases, we do not expressly refer to the sources from which these data are derived.

In this Quarterly Report on Form 10-Q, unless otherwise stated or as the context otherwise requires, references to “First Wave,” the “Company,” “we,” “us,” “our” and similar references are to First Wave BioPharma, Inc. and its subsidiaries on a consolidated basis. References to “First Wave BioPharma” refer to First Wave BioPharma, Inc. on an unconsolidated basis.

PART I

FINANCIAL INFORMATION

ITEM 1. UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

In our opinion, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting only of normal recurring adjustments) necessary to present fairly our financial position, results of operations, and cash flows for the interim periods presented. We have consolidated such financial statements in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). Therefore, such financial statements do not include all disclosures required by accounting principles generally accepted in the United States of America. In preparing these unaudited condensed consolidated financial statements, the Company has evaluated events and transactions for potential recognition or disclosure through the date the unaudited condensed consolidated financial statements were issued by filing with the SEC.

These financial statements should be read in conjunction with our audited financial statements for the year ended December 31, 2022 included in our Annual Report filed on Form 10-K, filed with the SEC on March 20, 2023.

The results of operations for the three and nine months ended September 30, 2023 are not necessarily indicative of the results to be expected for the fiscal year ending December 31, 2023.

FIRST WAVE BIOPHARMA, INC.

Notes to Unaudited Condensed Consolidated Financial Statements

September 30, 2023

Note 1 - The Company and Basis of Presentation

The Company

First Wave BioPharma, Inc. (“First Wave”) and its wholly-owned subsidiary, First Wave Bio, Inc. (“FWB”), are collectively referred to as the “Company”. Effective October 26, 2022, the Company’s wholly-owned subsidiary, AzurRx SAS, was dissolved. The Company is engaged in the research and development of targeted, non-systemic therapies for the treatment of patients with gastrointestinal (“GI”) diseases. Non-systemic therapies are non-absorbable drugs that act locally, i.e., in the intestinal lumen, skin or mucosa, without reaching an individual’s systemic circulation.

The Company is currently focused on developing a therapeutic pipeline with multiple Phase 2 clinical stage programs built around three proprietary technologies – the biologic Adrulipase, a recombinant lipase enzyme designed to enable the digestion of fats and other nutrients in cystic fibrosis and chronic pancreatitis patients with exocrine pancreatic insufficiency; Capeserod, a selective 5-HT4 receptor partial agonist which we will pursue for GI indications; and Niclosamide, an oral small molecule with anti-inflammatory properties for patients with inflammatory bowel diseases such as ulcerative colitis and Crohn’s disease.

The Company is developing its product candidates for a host of GI diseases where there are significant unmet clinical needs and limited therapeutic options, resulting in painful, life threatening and discomforting consequences for patients. Since its inception, the Company has devoted substantially all its efforts to research and development, business development, and raising capital, and has financed its operations through issuance of Common Stock, convertible preferred stock, convertible debt, and other debt/equity instruments.

Risks and Uncertainties

The Company is subject to risks and uncertainties common to early-stage companies in the biotechnology industry, including, but not limited to, development and regulatory success, development by competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with government regulations, and ability to secure additional capital to fund clinical trials and operations.

In February 2022, the Russian Federation and Belarus commenced a military action with the country of Ukraine. As a result of this action, various nations, including the United States, have instituted economic sanctions against the Russian Federation and Belarus. Further, the impact of this action and related sanctions on the world economy are not determinable as of the date of these financial statements and the specific impact on the Company’s financial condition, results of operations, and cash flows is also not determinable as of the date of these financial statements.

In addition, the Company is subject to other challenges and risks specific to its business, its ability to maintain compliance with the continued listing requirements of The Nasdaq Stock Market LLC and its ability to execute on its strategy, as well as risks and uncertainties common to companies in the biotechnology and pharmaceutical industries with development and commercial operations, including, without limitation, risks and uncertainties associated with: obtaining regulatory approval of its drug candidates; delays or problems in the manufacture and supply of its drug candidates; loss of single source suppliers or failure to comply with manufacturing regulations; identifying, acquiring or in-licensing additional products or drug candidates; pharmaceutical product development and the inherent uncertainty of clinical success; the challenges of protecting and enhancing our intellectual property rights; and complying with applicable regulatory requirements.

Principles of Consolidation

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and include the accounts of First Wave and its wholly owned subsidiaries, FWB and AzurRx SAS, which was dissolved effective October 26, 2022. Intercompany transactions and balances have been eliminated upon consolidation.

-9-

Table of Contents

In our opinion, the accompanying unaudited interim condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, which are necessary to present fairly our financial position, results of operations, and cash flows. The condensed consolidated balance sheet at December 31, 2022, has been derived from audited financial statements of that date. The unaudited interim condensed consolidated results of operations are not necessarily indicative of the results that may occur for the full fiscal year. Certain information and footnote disclosure normally included in financial statements prepared in accordance with GAAP have been omitted pursuant to instructions, rules, and regulations prescribed by the SEC. The Company believes that the disclosures provided herein are adequate to make the information presented not misleading when these unaudited interim condensed consolidated financial statements are read in conjunction with the audited financial statements and notes previously distributed in our Annual Report Form 10-K for the year ended December 31, 2022, filed with the SEC on March 20, 2023.

Going Concern Uncertainty

The accompanying unaudited interim condensed consolidated financial statements have been prepared as if the Company will continue as a going concern. The Company has incurred significant operating losses and negative cash flows from operations since inception. On September 30, 2023, the Company had cash and cash equivalents of approximately $3.3 million, accumulated deficit of approximately $180.2 million, and working capital of approximately $1.5 million. The Company has incurred recurring losses, has experienced recurring negative operating cash flows, and requires significant cash resources to execute its business plans. The Company anticipates having sufficient cash to fund planned operations through December 2023, however, the acceleration or reduction of cash outflows by Company management can significantly impact the timing for the need to raise additional capital to complete development of its products. Historically, the Company’s major sources of cash have been comprised of proceeds from various public and private offerings of its capital stock. The Company is dependent on obtaining additional working capital funding from the sale of equity and/or debt securities in order to continue to execute its development plans and continue operations.

Without adequate working capital, the Company may not be able to meet its obligations and continue as a going concern. These conditions raise substantial doubt about the Company’s ability to continue as a going concern one year from the date these financial statements are issued. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

​

Note 2 - Significant Accounting Policies and Recent Accounting Pronouncements

Use of Estimates

The accompanying unaudited condensed consolidated financial statements are prepared in conformity with GAAP and include certain 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 (including goodwill), and the reported amounts of revenue and expense during the reporting period, including contingencies. Accordingly, actual results may differ from those estimates.

Reverse Stock Split

On January 18, 2023, the Company effected a reverse stock split, whereby every seven shares of the Company’s issued and outstanding Common Stock was converted automatically into one issued and outstanding share of Common Stock, but without any change in the number of authorized shares of Common Stock and the par value per share.

On August 26, 2022, the Company effected a reverse stock split, whereby every thirty shares of the Company’s issued and outstanding common stock was converted automatically into one issued and outstanding share of common stock, but without any change in the number of authorized shares of common stock and the par value per share.

All share and per share amounts have been retroactively restated to reflect the reverse stock splits referenced above.

Cash, Cash Equivalents and Restricted Cash

The Company considers all highly liquid investments with maturities of three months or less from the date of purchase to be cash equivalents. All cash and cash equivalent balances were highly liquid at September 30, 2023 and December 31, 2022. As of September 30, 2023 and December 31, 2022, the Company has classified approximately $0.02 million as restricted cash.

-10-

Table of Contents

Concentrations of Credit Risk

Financial instruments that potentially expose the Company to concentrations of credit risk consist of cash. The Company primarily maintains its cash balances with financial institutions in federally insured accounts in the U.S. The Company may from time to time have cash in banks in excess of FDIC insurance limits. At September 30, 2023 the Company had approximately $3.2 million in one account in the U.S. which was in excess of these limits. The Company has not experienced any losses to date resulting from this practice. The Company mitigates its risk by maintaining the majority of its cash and equivalents with high quality financial institutions.

Fair Value Measurements

The Company follows Accounting Standards Codification (“ASC”) Topic 820-10, Fair Value Measurements and Disclosures (“ASC 820”), which among other things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability.

As a basis for considering such assumptions, a three-tier fair value hierarchy has been established, which prioritizes the inputs used in measuring fair value as follows:

Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities;

Level 2: Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and

Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions, which reflect those that a market participant would use.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the overall fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the financial instrument.

The Company recognizes transfers between levels as if the transfers occurred on the last day of the reporting period.

Foreign Currency Translation

For foreign subsidiaries with operations denominated in a foreign currency, assets and liabilities were translated to U.S. dollars, which was the functional currency, at period end exchange rates. Income and expense items were translated at average rates of exchange prevailing during the periods presented. Gains and losses from translation adjustments were accumulated in a separate component of stockholders’ equity up until the dissolution of AzurRx SAS in October 2022, at which time cumulative translation adjustments were recognized as a loss for the year ended December 31, 2022.

Goodwill

Goodwill represents the excess of the purchase price of the acquired business over the fair value of amounts assigned to assets acquired and liabilities assumed. Goodwill and other intangible assets with indefinite useful lives are reviewed for impairment annually or more frequently if events or circumstances indicate impairment may be present. Any excess in carrying value over the estimated fair value is charged to results of operations. The Company has not recognized any impairment charges through September 30, 2023 related to goodwill.

Impairment of Long-Lived Assets

The Company periodically evaluates its long-lived assets for potential impairment in accordance with ASC Topic 360, Property, Plant and Equipment (“ASC 360”). Potential impairment is assessed when there is evidence that events or changes in circumstances indicate that the carrying amount of an asset may not be recovered. Recoverability of these assets is assessed based on undiscounted expected future cash flows from the assets, considering a number of factors, including past operating results, budgets and economic projections, market trends and product development cycles. If impairments are identified, assets are written down to their estimated fair value. The Company has not recognized any impairment charges through September 30, 2023.

-11-

Table of Contents

Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in right-of-use (“ROU”) assets, and lease liability obligations are included in the Company’s balance sheets. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liability obligations represent its obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As the Company’s leases typically do not provide an implicit rate, the Company estimates its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The Company uses the implicit rate when readily determinable. The ROU asset also includes any lease payments made and excludes lease incentives and lease direct costs. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense is recognized on a straight-line basis over the lease term. Please refer to Note 13 for additional information.

License Agreements

The Company records payments related to license agreements for assets acquired that have not reached technological feasibility and which have no alternative future use, as research and development expenses. On September 13, 2023, the Company entered into a license agreement with Sanofi to license Capeserod, a selective 5-HT4 receptor partial agonist, which the Company will repurpose and develop for gastrointestinal (“GI”) indications. Under the terms of the agreement, the Company received from Sanofi an exclusive, global license for Capeserod and assumed responsibility for all future clinical development (see Note 12).

Research and Development

Research and development costs are charged to operations when incurred and are included in operating expense, except for goodwill related to patents. Research and development costs consist principally of compensation of employees and consultants that perform the Company’s research activities, payments to third parties for preclinical and non-clinical activities, expenses with clinical research organizations (“CROs”), investigative sites, consultants and contractors that conduct or provide other services relating to clinical trials, costs to acquire drug product, drug supply and clinical trial materials from contract development and manufacturing organization (“CDMOs”) and third-party contractors relating to chemistry, manufacturing and controls (“CMC”) efforts, the fees paid for and to maintain the Company’s licenses, and research and development costs related to Adrulipase, Capeserod, and Niclosamide. Depending upon the timing of payments to the service providers, the Company recognizes prepaid expenses or accrued expenses related to these costs. These accrued or prepaid expenses are based on management’s estimates of the work performed under service agreements, milestones achieved and experience with similar contracts. The Company monitors each of these factors and adjusts estimates accordingly.

Research and Development – Intellectual Property Acquired

The Company records intellectual property in asset acquisitions that have not reached technological feasibility and which have no alternative future use, as an expense at the acquisition date. On September 13, 2021, the Company entered into an agreement with FWB for the acquisition of intellectual property and patents for the worldwide, exclusive right to develop, manufacture, and commercialize proprietary formulations of Niclosamide for the fields of treating ICI-AC and COVID-19 in humans, which was accounted for as an asset acquisition (see Note 4).

Stock-Based Compensation

The Company’s board of directors (the “Board”) and stockholders have adopted and approved the Amended and Restated 2014 Omnibus Equity Incentive Plan (the “2014 Plan”) which took effect on May 12, 2014, and the 2020 Omnibus Equity Incentive Plan, which took effect on September 11, 2020 (the “2020 Plan”). From the effective date of the 2020 Plan, no new awards have been or will be made under the 2014 Plan. The Company accounts for its stock-based compensation awards to employees, consultants, and Board members in accordance with ASC Topic 718, Compensation-Stock Compensation (“ASC 718”). ASC 718 requires all stock-based payments to employees, consultants, and Board members, including grants of employee stock options, to be recognized in the statements of operations by measuring the fair value of the award on the date of grant and recognizing this fair value as stock-based compensation using a straight-line method over the requisite service period, generally the vesting period.

-12-

Table of Contents

For awards with performance conditions that affect their vesting, such as the occurrence of certain transactions or the achievement of certain operating or financial milestones, recognition of fair value of the award occurs when vesting becomes probable.

The Company estimates the grant date fair value of stock option awards using the Black-Scholes option-pricing model. The use of the Black-Scholes option-pricing model requires management to make assumptions with respect to the expected term of the option, the expected volatility of the Common Stock consistent with the expected life of the option, risk-free interest rates and expected dividend yields of the Common Stock.

Recent Accounting Pronouncements

In August 2020, the Financial Accounting Standards Board (the “FASB”) issued accounting pronouncement ASU 2020-06 – Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”) related to the measurement and disclosure requirements for convertible instruments and contracts in an entity’s own equity. The pronouncement simplifies and adds disclosure requirements for the accounting and measurement of convertible instruments and the settlement assessment for contracts in an entity’s own equity. As a smaller reporting company, as defined by the U.S. Securities and Exchange Commission (the “SEC”), this pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2023. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company early adopted ASU 2020-06 effective January 1, 2022.

In June 2016, the FASB issued accounting pronouncement ASU 2016-13 – Measurement of Credit Losses on Financial Statements (“ASU 2016-13”). The new standard requires that expected credit losses relating to financial assets measured on an amortized cost basis and available-for-sale debt securities be recorded through an allowance for credit losses. It also limits the amount of credit losses to be recognized for available-for-sale debt securities to the amount by which carrying value exceeds fair value and also requires the reversal of previously recognized credit losses if fair value increases. In November 2019, the FASB issued ASU 2019-10 – Financial Instruments – Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates, which amended the effective date for certain companies. The standard is effective for public companies eligible to be smaller reporting companies for annual and interim periods beginning after December 15, 2022. The Company adopted ASU 2016-13 effective for the year ended December 31, 2022 and its adoption did not have a material effect on its financial statements and related disclosures.

In June 2022, the FASB issued ASU 2022-03 - Fair Value Measurement, or Topic 820: Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions (“ASU 2022-03”). This new standard clarifies the guidance in Topic 820 when measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of an equity security and introduces new disclosure requirements for equity securities subject to contractual sale restrictions that are measured at fair value in accordance with Topic 820. The Company has assessed the impact of the update and determined it does not have a material impact on the accompanying financial statements and disclosures.

The Company has evaluated other recently issued accounting pronouncements and has concluded that the impact of recently issued standards that are not yet effective will not have a material impact on the Company’s financial position or results of operations upon adoption.

​

Note 3 - Fair Value Disclosures

Fair value is the price that would be received from the sale of an asset or paid to transfer a liability assuming an orderly transaction in the most advantageous market at the measurement date. U.S. GAAP establishes a hierarchical disclosure framework that prioritizes and ranks the level of observability of inputs used in measuring fair value.

Note 4 – Asset Acquisition

The Asset Acquisition

During the nine months ended September 30, 2022, the Company paid an aggregate of $2.4 million in cash towards the purchase price of FWB in accordance with the terms of an Agreement and Plan of Merger dated as of September 13, 2021 (the “Merger Agreement”) and a settlement agreement reached on November 21, 2021 (the “November 2021 Settlement Agreement”).

On May 19, 2022, Fortis Advisors LLC, the hired representative (in such capacity, the “Representative”) of the former stockholders of FWB in connection with the Merger Agreement, filed a complaint against the Company in the Court of Chancery in the State of Delaware (the “FWB Action”) for breach of contract and anticipatory repudiation or for unjust enrichment. The FWB Action sought specific performance of the Company’s obligations under the Merger Agreement and the November 2021 Settlement Agreement, including all payments then owed and to be owed to the Representative, and damages at the maximum amount permitted by law. On July 29, 2022, the Company reached an agreement with the Representative to settle the FWB Action and to restructure the Company’s obligations to the former FWB stockholders (the “July 2022 Term Sheet”). The Company agreed to pay the Representative: (i) $1.5 million in cash on July 29, 2022; (2) $1.0 million in cash no later than September 29, 2022 (the “Second Payment”); and (iii) $2.0 million on the earlier of November 30, 2022 and the completion by the Company of one or more qualifying equity offerings (collectively, the “Payments”). The Representative is also entitled to receive future cash payments conditioned on the achievement of certain development milestones for Adrulipase and to a percentage of any consideration received by the Company in the event of a license or sale of Adrulipase, subject to a cap. The Representative is also entitled to receive a percentage of the consideration received by the Company in the event of a license or sale of Niclosamide and will retain its existing milestone payment rights with respect to Niclosamide. In the event that the consideration received by the Company in connection with the sale or license of Adrulipase or Niclosamide consists of securities or other non-cash consideration, the Representative will have the right to elect either to receive its payment in such form of consideration or to cause the licensee or acquirer to assume the obligations described herein. In the event of a “Company Sale” (as defined in the July 2022 Term Sheet), the Representative is entitled to receive a pro rata share of the total consideration received by the Company or its stockholders up to $4.0 million (plus any unpaid Payments whether or not then due) based on a formula set forth in the July 2022 Term Sheet. In certain circumstances, the Representative has the right to treat a “Company Sale” as a sale of ardulipase or Niclosamide, as applicable, and to treat the Company Sale as a sale of the related asset and to receive the consideration with respect thereto described herein.

In the July 2022 Term Sheet, the Representative agreed to stay the FWB Action for a period of 90 days and to eliminate the Company’s obligation to pay a portion of any offering proceeds to the Representative. In addition, the Company’s obligation to use commercially reasonable efforts to develop Niclosamide will be deferred for a period of 24 months from the date of the July 2022 Term Sheet. Effective upon the Second Payment, the Representative dismissed the FWB Action with prejudice and extinguished the remaining fixed payment obligations owed to the former FWB shareholders. On November 30, 2022, the Company entered into a formal settlement agreement with the Representative on substantially the same terms as the July 2022 Term Sheet (the “November 2022 Settlement Agreement”).

Accounting Treatment

Under the July 2022 Term Sheet, the $1.5 million in cash due and paid on July 29, 2022, as well as the Second Payment due and paid in September 2022, were recorded as a reduction to current liabilities for the three months ended September 30, 2022. Effective upon the Second Payment, the approximately $10.1 million of remaining fixed payment obligations previously owed to the former FWB shareholders was settled. The third payment obligation of $2.0 million due and paid by November 30, 2022 was recorded as research and development expense in the three months ended December 31, 2022.

The remaining unachieved potential milestone payments and revenue share are not yet considered probable, therefore have not been accrued as of September 30, 2023. Depending on the status of development at the time a contingent payment is recognized, the Company may determine that the payment should be expensed as research and development or be capitalized as an intangible asset. This determination will be based on the facts and circumstances that exist at the time a contingent payment is recognized.

As Converted Shares include all outstanding shares of Common Stock and all shares of Common Stock issuable upon the conversion of outstanding preferred stock, warrants and other convertible securities, but will not include any shares of Common Stock issuable upon the exercise of options and other convertible securities issued pursuant to either the 2014 Plan or the 2020 Plan. The number of shares permitted to be issued as “incentive stock options” (“ISOs”) is 7,142 under the 2020 Plan.

On April 20, 2023, the Company’s board of directors approved an amendment (i) increasing the number of shares of Common Stock available for issuance under the 2020 Plan from 317,480 to 1,167,480 and (ii) increasing the number of shares of our Common Stock otherwise available under the 2020 Plan that may be granted as ISOs to 5,000,000 shares. The board of directors directed that the amendment be submitted to the stockholders of the Company at the Company’s annual meeting of stockholders. On June 22, 2023, the stockholders approved the amendment to the 2020 Plan at the annual meeting of stockholders.

As of January 1, 2023, the number of shares of Common Stock available for issuance under the 2020 Plan automatically increased to 317,480 under the 2020 Plan’s evergreen provision.

As of June 22, 2023, as a result of approval at the annual shareholders’ meeting, the number of shares of Common Stock available for issuance under the 2020 Plan increased to 1,167,480.

As of September 30, 2023, there were an aggregate of 1,024 total shares available (but un-issuable) under the 2014 Plan, of which 732 are issued and outstanding, and 292 shares are reserved subject to issuance of restricted stock and RSUs.

As of September 30, 2023, 1,167,480 total shares were authorized under the 2020 Plan, of which 158,313 were issued and outstanding and 1,009,167 shares were available for potential issuances.

During the nine months ended September 30, 2023 and 2022, the Board approved the grant of options to purchase 5,000 and 3,266 shares of Common Stock, respectively. All option grants were pursuant to the 2020 Plan. In general, options granted under the 2020 Plan vest monthly over a 36-month period.

During the nine months ended September 30, 2023 and 2022, stock options to purchase 11 and 678 shares of Common Stock, respectively, were forfeited. During the nine months ended September 30, 2023, stock options to purchase 109 shares of Common Stock expired. During the nine months ended September 30, 2022, stock options to purchase 535 shares of Common Stock were cancelled.

For the nine months ended September 30, 2023 and 2022, the fair value of each option grant has been estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:

​

​ | ​ | ​ | ​ | ​ | ​
​ |  | 2023 |  | 2022 |
Contractual term (in years) |  | 6.50 | ​ | 6.50 | ​
Expected Volatility |  | 98.80 | % | 90.92 | %
Risk-free interest rate |  | 4.08 | % | 1.11 | %
Expected Dividend yield |  | 0 | % | 0 | %

​

Using the Black-Scholes Option Pricing Model, the estimated weighted average fair value of an option to purchase one share of common stock granted during the nine months ended September 30, 2023 and 2022 was $3.05 and $223.72, respectively.

Restricted Stock and Restricted Stock Units

Restricted stock refers to shares of Common Stock subject to vesting based on certain service, performance, and market conditions. Restricted stock units (“RSUs”) refer to an award which constitutes a promise to grant shares of Common Stock at the end of a specified restriction period.

As of September 30, 2023 and 2022, under the 2014 Plan, the Company had 130 shares of restricted stock outstanding and an aggregate unrecognized restricted Common Stock expense of approximately $388,000, which will be recognized when vesting of certain milestones become probable.

Approximately $0.4 million of this unrecognized expense will be recognized over the average remaining vesting term of the stock awards of 0.66 years. Approximately $0.2 million of this unrecognized expense will vest upon achieving certain clinical and/or corporate milestones. The Company will recognize the expense related to these milestones when the milestones become probable.

As of September 30, 2022, the Company had unrecognized stock-based compensation expense of approximately $0.9 million. Approximately $0.4 million of this unrecognized expense will be recognized over the average remaining vesting term of the stock options of 8.44 years.

Note 12 – Agreements

License Agreement with Sanofi

On September 13, 2023, the Company entered into a License Agreement with Sanofi, pursuant to which the Company received a license to obtain certain exclusive worldwide rights to develop and commercialize Capeserod, a selective 5-HT4 receptor partial agonist which the Company intends to repurpose and develop for gastrointestinal indications.

The Company paid Sanofi an upfront payment of $500,000 in October 2023 and Sanofi will be eligible to receive up to $46 million in potential development and regulatory milestone payments and up to $235 million in potential commercial milestone payments. Sanofi will also be eligible to receive mid-to-high single-digit royalties on net sales, as well as a percentage of sublicense and transfer revenues with respect to Capeserod. Sanofi will also have a right of first refusal with respect to Capeserod out-licensing transactions.

The upfront payment of $500,000 was recorded as research and development expense in the three and nine months ended September 30, 2023. Depending on the status of development at the time a contingent payment is recognized, the Company may determine that the payment should be expensed as research and development or be capitalized as an intangible asset. This determination will be based on the facts and circumstances that exist at the time a contingent payment is recognized.

The License Agreement shall expire on a country-by-country basis upon the later of: (i) the expiration of the last to expire valid claim of an applicable patent in such country covering such licensed product, (ii) the expiration of the regulatory exclusivity for such licensed product in the applicable country and (iii) the tenth anniversary of the date of first commercial sale of a licensed product in such country. Each party may terminate the License Agreement if the other party materially breaches its obligations under the License Agreement and fails to cure such material breach within 60 days from the date of such notice of breach, except in the case of payment breach, as to which the breaching party will have only a ten-day cure period. Sanofi may terminate the License Agreement upon any bankruptcy proceedings by the Company. The Company may terminate the License Agreement by providing Sanofi with at least 60 days prior written notice; provided, however, that Sanofi shall be entitled to any and all payments due and owed to Sanofi prior to the effective date of termination.

Note 13 – Leases

The Company leases its office under an operating lease which is subject to various rent provisions and escalation clauses.

The Company is a party to one real property operating lease for the rental of office space.

Note 14 - Net (Loss) Income per Common Share

Basic net loss per share is computed by dividing net loss available to Common Stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflect, in periods in which they have a dilutive effect, the impact of common shares issuable upon exercise of stock options and warrants and conversion of convertible debt that are not deemed to be anti-dilutive. The dilutive effect of the outstanding stock options and warrants is computed using the treasury stock method.

​

Note 16 - Subsequent Event

The Company evaluated subsequent events and transactions that occurred after the balance sheet date up to the date that the financial statements were available to be issued. The Company did not identify any subsequent events that would have required adjustment or disclosure in the financial statements except for the item noted below.

On October 26, 2023, the Company received a notice from the Listing Qualifications Staff (the “Staff”) of The Nasdaq Stock Market LLC (“Nasdaq”) indicating that in connection with the July 2023 Offering, the Company was not in compliance with Nasdaq’s shareholder approval requirements set forth in listing rule 5635(d), which requires prior shareholder approval for transactions, other than public offerings, involving the issuance of 20% or more of the pre-transaction shares outstanding at less than the Minimum Price. The Company has 45 calendar days to submit a plan to regain compliance.

Readers are cautioned not to place undue reliance on these forward-looking statements.

Overview

We are engaged in the research and development of targeted, non-systemic therapies for the treatment of patients with gastrointestinal (“GI”) diseases. Non-systemic therapies are non-absorbable drugs that act locally, i.e., in the intestinal lumen, skin or mucosa, without reaching an individual’s systemic circulation.

We are currently focused on developing a therapeutic pipeline with multiple Phase 2 clinical stage programs built around three proprietary technologies –the biologic Adrulipase, a recombinant lipase enzyme designed to enable the digestion of fats and other nutrients in cystic fibrosis and chronic pancreatitis patients with exocrine pancreatic insufficiency; Capeserod, a selective 5-HT4 receptor partial agonist which we will pursue for GI indications; and Niclosamide, an oral small molecule with anti-inflammatory properties for patients with inflammatory bowel diseases such as ulcerative colitis and Crohn’s disease.

Our Adrulipase programs are focused on the development of an oral, non-systemic, biologic capsule for the treatment of exocrine pancreatic insufficiency (“EPI”) in patients with cystic fibrosis (“CF”) and chronic pancreatitis (“CP”). Our goal is to provide CF and CP patients with a safe and effective therapy to control EPI that is non-animal derived and offers the potential to dramatically reduce their daily pill burden. In July 2023, we announced topline results from our Phase 2b monotherapy bridging study using a new enteric microgranule formulation of Adrulipase While the initial data from the study indicated that the enhanced Adrulipase formulation was safe and well tolerated and demonstrated an improvement over prior formulations of Adrulipase, it also indicated that it is likely that the primary efficacy endpoint was not achieved. We are continuing to assess this data, along with secondary efficacy endpoint data, and plan to schedule a Type C meeting with the FDA in 2024 to discuss next steps for the Adrulipase program.

Our Capeserod program was in-licensed from Sanofi in September 2023. Sanofi conducted Phase 1 and Phase 2 Central Nervous System (“CNS”) trials with over 600 patients. In Sanofi’s Phase 1 CNS trial, Capeserod appeared safe and well-tolerated. Research on Capeserod and subsequent artificial intelligence (“AI”) empowered analyses suggest that the drug possesses a unique mechanism of action that is applicable to several GI indications underserved by currently available therapeutics. We plan to repurpose Capeserod for GI indications and expect to initiate a Phase 2 clinical development program in either pediatric ulcerative colitis or gastroparesis. Sanofi retains the right of first refusal to develop and commercialize Capeserod.

-27-

Table of Contents

Our Niclosamide programs leverage proprietary oral and topical formulations to address multiple GI conditions, including inflammatory bowel diseases (“IBD”) indications. In 2022 we advanced two separate Phase 2 clinical programs of our Niclosamide formulations, including FW-COV for Severe Acute Respiratory Syndrome Coronavirus 2 (“COVID-19”) GI infections, and FW-UP for ulcerative proctitis (“UP”) and ulcerative proctosigmoiditis (“UPS”).

We announced the completion of enrollment in the FW-COV trial in January 2022 and topline results in August 2022. In September 2022 we announced that we would no longer pursue the anti-viral COVID-GI clinical indication as a result of the mixed results from the FW-COVID-19 trial. Additionally, we are devoting fewer resources to the FW-UP/UPS Niclosamide program due to inconclusive data from a small Phase 2 trial in Europe, the need for a new FDA-IND cleared protocol, and financial constraints.

We are further developing FW-ICI-AC for Immune Checkpoint Inhibitor-associated colitis (“ICI-AC”) and diarrhea in advanced stage oncology patients, which received FDA IND clearance for a Phase 2a clinical trial in October 2021, and two pre-IND programs of our Niclosamide therapies for additional IBD indications, including FW-UC for ulcerative colitis (“UC”) and FW-CD for Crohn’s disease (“CD”). However, the FW-ICI-AC program is currently on hold due to financial constraints.

Nasdaq Continued Listing Requirements

On August 17, 2023, we received a letter from the Listing Qualifications Staff (the “Staff”) of The Nasdaq Stock Market LLC (“Nasdaq”) indicating that we were not in compliance with the $2.5 million minimum stockholders’ equity requirement for continued listing of our common stock on Nasdaq as set forth in Nasdaq Listing Rule 5550(b)(1) (the “Minimum Stockholder’s Equity Rule”). In that regard, we reported stockholders’ equity of $881,960 in our Quarterly Report on Form 10-Q for the period ended June 30, 2023 (we did not then, and do not now, meet the alternative compliance standards relating to the market value of listed securities of $35 million or net income from continuing operations of $500,000 in the most recently completed fiscal year or in two of the last three most recently completed fiscal years). On October 2, 2023, we submitted a plan to the Staff to regain compliance with the Minimum Stockholders’ Equity Rule. If our plan is accepted, the Staff can grant an extension of up to 180 calendar days from the date of the letter to evidence compliance. We are awaiting a determination from the Staff regarding our request for an extension to regain compliance.

On August 24, 2023, we received notice from the Staff indicating that, based upon the closing bid price of our common stock for the prior 30 consecutive business days, we were not currently in compliance with the requirement to maintain a minimum bid price of $1.00 per share for continued listing on Nasdaq as set forth in Nasdaq Listing Rule 5550(a)(2) (the “Bid Price Rule”). We have 180 days from August 24, 2023, or through February 20, 2024, to regain compliance with the Bid Price Rule.

On October 26, 2023, we received a notice from the Staff indicating that in connection with our July 2023 Offering, we were not in compliance with Nasdaq’s shareholder approval requirements set forth in listing rule 5635(d), which requires prior shareholder approval for transactions, other than public offerings, involving the issuance of 20% or more of the pre-transaction shares outstanding at less than the Minimum Price. We have 45 calendar days to submit a plan to regain compliance. If our plan is accepted, the Staff can grant an extension of up to 180 calendar days from the date of the letter to evidence compliance.

Liquidity and Capital Resources

To date, we have not generated any revenues and have experienced net losses and negative cash flows from our activities.

As of September 30, 2023, we had cash and cash equivalents of approximately $3.3 million, and had sustained cumulative losses attributable to common stockholders of approximately $180.2 million. We anticipate having sufficient cash to fund planned operations through December 2023, however, the acceleration or reduction of cash outflows by management can significantly impact the timing for the need to raise additional capital to complete development of our products. We have not yet achieved profitability and anticipate that we will continue to incur net losses for the foreseeable future. We expect that our expenses will continue to grow and, as a result, we will need to generate significant product revenues to achieve profitability. We may never achieve profitability. As such, we are dependent on obtaining, and are continuing to pursue, the necessary funding from outside sources, including obtaining additional funding from the sale of securities in order to continue our operations. Without adequate funding, we may not be able to meet our obligations. We believe these conditions may raise substantial doubt about our ability to continue as a going concern.

-28-

Table of Contents

We have funded our operations to date primarily through the issuance of debt, convertible debt securities, preferred stock, as well as the issuance of Common Stock in various public offerings and private placement transactions. We expect to incur substantial expenditures in the foreseeable future for the development of Adrulipase, Capeserod, Niclosamide and any other drug candidates. We will require additional financing to develop our drug candidates, run clinical trials, prepare regulatory filings and obtain regulatory approvals, fund operating losses, and, if deemed appropriate, establish manufacturing, sales and marketing capabilities. Our current financial condition raises substantial doubt about our ability to continue as a going concern. Our failure to raise capital as and when needed would have a material adverse impact on our financial condition, our ability to meet our obligations, and our ability to pursue our business strategies. We will seek funds through additional equity and/or debt financings, collaborative or other arrangements with corporate sources, or through other sources of financing.

Although, we are primarily focused on the development of our drug candidates, including Adrulipase, Capeserod, and Niclosamide, we are also opportunely focused on expanding our product pipeline of clinical assets through collaborations, and also through acquisitions of products and companies. We are continually evaluating potential asset acquisitions business combinations, and other partnership opportunities. To finance such acquisitions, we might raise additional equity capital, incur additional debt, or both.

We are able to sell securities on a shelf registration statement pursuant to the ATM Agreement with H.C. Wainwright & Co., LLC. Under current SEC regulations, because our public float was less than $75 million at the relevant measurement period pursuant to General Instruction I.B.6. to Form S-3, the amount we can raise through primary public offerings of securities in any subsequent twelve-month period under our shelf registration statement is limited to an aggregate of one-third of our public float until such time, if any, as our public float is $75 million or more. As a result, we are currently restricted from using the ATM Agreement.

Our ability to issue securities is subject to market conditions. Each issuance under a shelf registration statement will require the filing of a prospectus supplement identifying the amount and terms of the securities to be issued.

Research and Development Expenses

Research and development expenses include expenses primarily relating to the development of our Adrulipase, Capeserod and Niclosamide drug candidates.

Research and development expenses for the three months ended September 30, 2023 totaled approximately $1.0 million, an increase of approximately $0.2 million, or 28%, over the approximately $0.8 million for the three months ended September 30, 2022. The increase in research and development expenses was primarily attributable to the up-front payment of $0.5 million due to Sanofi recorded in the three months ended September 30, 2023 per the executed license agreement for Capeserod. This increase was partially offset by decreases of approximately $0.2 million in personnel related costs and approximately $0.1 million in manufacturing costs related to Adrulipase.

Research and development recovery, related to intellectual property acquired, for the three months ended September 30, 2023, totaled $0 million as compared to $8.1 million for the three months ended September 30, 2022. This decrease was due to the liability reduction recorded in the three months ended September 30, 2022 of approximately $8.1 million in accordance with the July 2022 Term Sheet with Fortis Advisors LLC.

Table of Contents

We expect research and development expenses to decrease during the remainder of this fiscal year as we close out the Phase 2b Adrulipase SPAN clinical trial.

General and Administrative Expenses

General and administrative expenses include expenses primarily relating to our overall operations and being a public company, including personnel, legal and financial professional services, insurance, corporate communication and investor relations, listing and compliance related costs, rent, and expenses associated with obtaining and maintaining intellectual property and patents, among others.

General and administrative expenses for the three months ended September 30, 2023 totaled approximately $2.4 million, a decrease of approximately $0.5 million, or 17% over the approximately $2.9 million recorded for the three months ended September 30, 2022. The decrease in general and administrative expenses was primarily due to decreases of approximately $0.5 million in public company costs, including investor relations and corporate communications; and approximately $0.3 million in professional fees, including audit and legal expenses; partially offset by an increase of approximately $0.3 million in non-cash stock-based compensation costs.

We expect general and administrative expenses to remain stable during the remainder of this fiscal year.

Other Expenses

Other expenses for the three months ended September 30, 2023 were essentially flat with other expenses recorded for the three months ended September 30, 2022.

Net Loss (Income)

As a result of the factors above, our net loss for the three months ended September 30, 2023 totaled approximately $3.4 million, an increase of approximately $7.8 million, or 157%, over the approximately $4.4 million net income recorded for the three months ended September 30, 2022.

Research and Development Expenses

Research and development expenses include expenses primarily relating to the development of our Adrulipase, Capeserod and Niclosamide drug candidates.

Research and development expenses for the nine months ended September 30, 2023 totaled approximately $3.7 million, a decrease of approximately $4.9 million, or 57%, over the approximately $8.7 million recorded for the nine months ended September 30, 2022. The decrease in research and development expenses was primarily attributable to decreases of approximately $3.7 million for clinical related expenses in connection with our Phase 2b Adrulipase SPAN clinical trial during the nine months ended September 30, 2023, as compared to our Phase 2 RESERVOIR COVID-19 GI clinical trial during the nine months ended September 30, 2022; approximately $1.0 million in manufacturing costs related to Adrulipase; and approximately $0.9 million in personnel related costs. These decreases were partially offset by the up-front payment of $0.5 million due to Sanofi per the executed license agreement for Capeserod.

General and administrative expenses include expenses primarily relating to our overall operations and being a public company, including personnel, legal and financial professional services, insurance, corporate communication and investor relations, listing and compliance related costs, rent, and expenses associated with obtaining and maintaining intellectual property and patents, among others.

General and administrative expenses for the nine months ended September 30, 2023 totaled approximately $8.0 million, a decrease of approximately $1.9 million, or 19% over the approximately $9.8 million recorded for the nine months ended September 30, 2022. The decrease in general and administrative expenses was primarily due to decreases of approximately $0.8 million in professional fees, including audit and legal expenses; approximately $0.6 million in public company costs, including investor relations and corporate communications; and approximately $0.3 million in corporate costs.

We expect general and administrative expenses to remain stable during the remainder of this fiscal year.

Other Expenses

Other expenses for the nine months ended September 30, 2023 decreased approximately $0.2 million, or 93% over the approximately $0.2 million of other expenses recorded for the nine months ended September 30, 2022. The decrease in other expenses was mainly due to the $0.2 million of Waiver fees paid in the nine months ended September 30, 2023.

Net Loss

As a result of the factors above, our net loss for the nine months ended September 30, 2023 totaled approximately $11.7 million, an increase of approximately $1.1 million, or 10%, over the approximately $10.6 million recorded for the nine months ended September 30, 2022.

-31-

Table of Contents

Net cash used in operating activities during the nine months ended September 30, 2022 of approximately $16.8 million was primarily attributable to our net loss of approximately $10.6 million and the decrease in other liabilities in accordance with the July 2022 Term Sheet of approximately $8.1 million, partially offset by non-cash expenses of approximately $0.9 million, mainly related to common stock issued to consultants of approximately $0.1 million and stock-based compensation of approximately $0.7 million, as well as increases in accounts payable and accrued expense of approximately $0.8 million and a decrease in prepaid expenses of $0.6 million.

Investing Activities

For the nine months ended September 30, 2023 and 2022, we did not use any cash for investing activities.

Financing Activities

Net cash provided by financing activities of approximately $10.9 million for the nine months ended September 30, 2023 was due to the net proceeds of approximately $5.9 million from the exercise of warrants, the net proceeds of approximately $5.5 million from the March 2023 and July 2023 offerings of our common stock, partially offset by repayments of approximately $0.6 million related to the note payable.

Net cash provided by financing activities of approximately $10.2 million for the nine months ended September 30, 2022 was primarily due to the net proceeds of approximately $8.0 million from the March 2022 registered direct offering of our common stock and warrants, the issuance of Common Stock of approximately $7.7 million from sales made under our ATM offering program, partially offset by approximately $4.9 million of cash payments made related to the Merger Agreement and July 2022 Term Sheet, as well as repayments of approximately $0.6 million related to the note payable.

Critical Accounting Policies and Estimates

Our accounting policies are essential to understanding and interpreting the financial results reported on the consolidated financial statements. The significant accounting policies used in the preparation of our consolidated financial statements are summarized in Note 2 to the consolidated financial statements and notes thereto found in our Annual Report on Form 10-K for the year ended December 31, 2022. Certain of those policies are considered to be particularly important to the presentation of our financial results because they require us to make difficult, complex or subjective judgments, often as a result of matters that are inherently uncertain.

During the nine months ended September 30, 2023, there were no material changes to matters discussed under the heading “Critical Accounting Policies and Significant Judgments and Estimates” in Part II, Item 7 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.

PART II

OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

On January 27, 2023, David Hoffman, a former member of the Company’s board of directors, filed a complaint in the Court of Chancery of the State of Delaware against the Company seeking advancement of his attorneys’ fees and expenses relating to certain aspects of his service as a director of the Company (the “Complaint”). The Complaint alleges that Mr. Hoffman is entitled to reimbursement of approximately $250,000 of alleged fees and expenses he has purportedly incurred in the lawsuit filed in the Court of Chancery. The case went to trial in May 2023 and the court found in favor of the Company in September 2023. Mr. Hoffman filed a motion to reargue or amend in October 2023 and the court denied this request.

ITEM 1A. RISK FACTORS

You should carefully consider the factors discussed in Part I, Item 1A., “Risk Factors” in our Annual Report for the fiscal year ended December 31, 2022, which could materially affect our business, financial position, or future results of operations. The risks described in our Annual Report for the fiscal year ended December 31, 2022, are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial position, or future results of operations. We may disclose changes to such factors or disclose additional factors from time to time in our future filings with the SEC. The risk factor set forth below supplements and updates the risk factors previously disclosed and should be read together with the risk factors described in our Annual Report for the fiscal year ended December 31, 2022 and with any risk factors we may include in subsequent periodic filings with the SEC.

Our failure to maintain compliance with Nasdaq’s continued listing requirements could result in the delisting of our Common Stock.

Our common stock is currently listed for trading on The Nasdaq Stock Market LLC. We must satisfy the continued listing requirements of Nasdaq, to maintain the listing of our common stock on The Nasdaq Stock Market LLC.

On August 17, 2023, we received notice from the Listing Qualifications Staff (the “Staff”) of The Nasdaq Stock Market LLC (“Nasdaq”) indicating that we were not in compliance with the $2.5 million minimum stockholders’ equity requirement for continued listing of the Common Stock on Nasdaq, as set forth in Nasdaq Listing Rule 5550(b)(1) (the “Minimum Stockholders’ Equity Rule”). In that regard, we reported a stockholders’ deficit of $(881,960) in our Quarterly Report on Form 10-Q for the period ended June 30, 2023 (we did not then, and do not now, meet the alternative compliance standards relating to the market value of listed securities of $35 million or net income from continuing operations of $500,000 in the most recently completed fiscal year or in two of the last three most recently completed fiscal years). On October 2, 2023, we submitted a plan to the Staff to regain compliance with the Minimum Stockholders’ Equity Rule.

On August 24, 2023, we received notice from the Staff indicating that, based upon the closing bid price of our common stock for the prior 30 consecutive business days, we were not currently in compliance with the requirement to maintain a minimum bid price of $1.00 per share for continued listing on Nasdaq as set forth in Nasdaq Listing Rule 5550(a)(2) (the “Bid Price Rule”). We have 180 days from August 24, 2023, or through February 20, 2024, to regain compliance with the Bid Price Rule.

On October 26, 2023, we received notice from the Staff of Nasdaq indicating that, in connection with our July 2023 Offering, we were not in compliance with Nasdaq’s shareholder approval requirements set forth in Listing Rule 5635(d), which requires prior shareholder approval for transactions, other than public offerings, involving the issuance of 20% or more of the pre-transaction shares outstanding at less than the Minimum Price. We have 45 calendar days to submit a plan to regain compliance. If our plan is accepted, Nasdaq can grant an extension of up to 180 calendar days from the date of the letter to evidence compliance.

There can be no assurance that we will be able to regain and sustain compliance with all applicable requirements for continued listing on The Nasdaq Stock Market LLC. In the event that we are unable to regain and sustain compliance with all applicable requirements for continued listing on the Nasdaq, our common stock may be delisted from Nasdaq.

-34-

Table of Contents

If our common stock were delisted from Nasdaq, trading of our common stock would most likely take place on an over-the-counter market established for unlisted securities, such as the OTCQB or the Pink Market maintained by OTC Markets Group Inc. An investor would likely find it less convenient to sell, or to obtain accurate quotations in seeking to buy, our common stock on an over-the-counter market, and many investors would likely not buy or sell our common stock due to difficulty in accessing over-the-counter markets, policies preventing them from trading in securities not listed on a national exchange or other reasons. In addition, as a delisted security, our common stock would be subject to SEC rules as a “penny stock,” which impose additional disclosure requirements on broker-dealers. The regulations relating to penny stocks, coupled with the typically higher cost per trade to the investor of penny stocks due to factors such as broker commissions generally representing a higher percentage of the price of a penny stock than of a higher-priced stock, would further limit the ability of investors to trade in our common stock. In addition, delisting would materially and adversely affect our ability to raise capital on terms acceptable to us, or at all, and may result in the potential loss of confidence by investors, suppliers, customers and employees and fewer business development opportunities. For these reasons and others, delisting would adversely affect the liquidity, trading volume and price of our common stock, causing the value of an investment in us to decrease and having an adverse effect on our business, financial condition and results of operations, including our ability to attract and retain qualified employees and to raise capital.

If we breach our license or other intellectual property-related agreements for our product candidates or otherwise experience disruptions to our business relationships with our licensor, we could lose the ability to continue the development and commercialization of our product candidates.

On September 13, 2023, we entered into a license agreement with Sanofi (the “Sanofi License Agreement”), pursuant to which we received a license to obtain certain exclusive worldwide rights to develop and commercialize Capeserod, a selective 5-HT4 receptor partial agonist which we intend to repurpose and develop for gastrointestinal indications. Our license may not cover all intellectual property rights owned or controlled by our licensor and relevant to our product candidates. If we have not obtained a license to all intellectual property rights owned or controlled by our licensor that are relevant to our product candidates, we may need to obtain additional licenses to such intellectual property rights which may not be available on an exclusive basis, on commercially reasonable terms or at all. In addition, if our licensor breaches such agreement, we may not be able to enforce such agreements against our licensor or their parent entity or affiliates. Under the Sanofi License Agreement, in exchange for licensing to us the right to develop and commercialize the applicable product candidate, Sanofi will be eligible to receive from us milestone payments, tiered royalties from commercial sales of such product candidates, assuming relevant approvals from government authorities are obtained, or other payments.

If we fail to meet any of our obligations under our license and intellectual property-related agreements, our licensors may have the right to terminate our licenses and sublicenses and, upon the effective date of such termination, have the right to re-obtain the licensed and sublicensed technology and intellectual property. If any of our licensors terminate any of our licenses or sublicenses, we will lose the right to develop and commercialize our applicable product candidates and other third parties may be able to market product candidates similar or identical to ours. In such case, we may be required to provide a grant back license to the licensors under our own intellectual property with respect to the terminated products. While we would expect to exercise all rights and remedies available to us, including seeking to cure any breach by us, and otherwise seek to preserve the intellectual property rights licensed and sublicensed to us, we may not be able to do so in a timely manner, at an acceptable cost or at all. In particular, some of the milestone payments are payable upon our product candidates reaching development milestones before we have commercialized, or received any revenue from, sales of such product candidate, and we cannot guarantee that we will have sufficient resources to make such milestone payments. Any uncured, material breach under the license agreements could result in our loss of exclusive rights and may lead to a complete termination of our rights to the applicable product candidate. Any of the foregoing could have a material adverse effect on our business, financial conditions, results of operations and prospects.

In addition, disputes may further arise regarding intellectual property subject to a license agreement, including, but not limited to:

​

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

| ● | the extent to which our technology and processes infringe, misappropriate or otherwise violate intellectual property of the licensor that is not subject to the licensing agreement;

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

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

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

| ● | the priority of invention of patented technology.

​

-35-

Table of Contents

In addition, the agreements under which we currently license intellectual property or technology from third parties are complex, and certain provisions in such agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant intellectual property or technology, or increase what we believe to be our financial or other obligations under the relevant agreement, either of which could have a material adverse effect on our business, financial condition, results of operations, and prospects. Moreover, if disputes over intellectual property that we have licensed or sublicensed prevent or impair our ability to maintain our current licensing arrangements on commercially acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates, which could have a material adverse effect on our business, financial conditions, results of operations and prospects.

If we experience disruptions to our business relationships with our licensors, we could lose the ability to continue to source, develop and commercialize our product candidates, including ultimately losing our rights to such product candidates.
