The accompanying 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 intangible assets), and the reported amounts of revenue and expense during the reporting period, including contingencies. Accordingly, actual results may differ from those estimates

The Company considers all highly liquid investments with maturities of three months or less from date of purchase to be cash equivalents. All cash and cash equivalent balances were highly liquid at December 31, 2021 and 2020, respectively.

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 December 31, 2021 and 2020, the Company had approximately $7.5 million and $2.7 million, respectively, in one account in the U.S. 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.

In August 2019, management determined that it was a victim of a cyber-related fraud whereby a hacker impersonated one of the Company’s key vendors to redirect payments, totaling approximately $420,000. The Company, including the Audit Committee, completed its investigation and is reviewing all available avenues of recovery, including from the Company’s financial institution to recover the payments. As of December 31, 2021, the Company had recovered approximately $50,000 from its financial institution but management is unable to determine the probability of recovering anything further from the cyber-related fraud. As a result of the cyber-related fraud, the Company has instituted additional controls and procedures and all employees now undergone cybersecurity training.

Detachable warrants issued in conjunction with debt are recorded at their relative fair value, if they are determined to be equity instrument, or their respective fair values, if they are determined to be liability instruments, and recorded as a debt discount. Conversion features that are in the money at the commitment date constitute a beneficial conversion feature that is measured at its intrinsic value and recognized as debt discount. Debt discount is amortized as interest expense over the maturity period of the debt using the effective interest method. Contingent beneficial conversion features are recognized when the contingency has been resolved.

Debt issuance costs are recorded as a direct reduction of the carrying amount of the related debt. Debt issuance costs are amortized over the maturity period of the related debt instrument using the effective interest method.

Significant Accounting Policies and Recent Accounting Pronouncements [Abstract]
Significant Accounting Policies and Recent Accounting Pronouncements	Note 2 - Significant Accounting Policies and Recent Accounting Pronouncements Use of Estimates The accompanying 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 intangible assets), and the reported amounts of revenue and expense during the reporting period, including contingencies. Accordingly, actual results may differ from those estimates Cash and Cash Equivalents The Company considers all highly liquid investments with maturities of three months or less from date of purchase to be cash equivalents. All cash and cash equivalent balances were highly liquid at December 31, 2021 and 2020, respectively. 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 December 31, 2021 and 2020, the Company had approximately $7.5 million and $2.7 million, respectively, in one account in the U.S. 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. The Company also has exposure to foreign currency risk as its subsidiary in France has a functional currency in Euros. Cyber-Related Fraud In August 2019, management determined that it was a victim of a cyber-related fraud whereby a hacker impersonated one of the Company’s key vendors to redirect payments, totaling approximately $420,000. The Company, including the Audit Committee, completed its investigation and is reviewing all available avenues of recovery, including from the Company’s financial institution to recover the payments. As of December 31, 2021, the Company had recovered approximately $50,000 from its financial institution but management is unable to determine the probability of recovering anything further from the cyber-related fraud. As a result of the cyber-related fraud, the Company has instituted additional controls and procedures and all employees now undergone cybersecurity training. Debt Instruments Detachable warrants issued in conjunction with debt are recorded at their relative fair value, if they are determined to be equity instrument, or their respective fair values, if they are determined to be liability instruments, and recorded as a debt discount. Conversion features that are in the money at the commitment date constitute a beneficial conversion feature that is measured at its intrinsic value and recognized as debt discount. Debt discount is amortized as interest expense over the maturity period of the debt using the effective interest method. Contingent beneficial conversion features are recognized when the contingency has been resolved. Debt Issuance Costs Debt issuance costs are recorded as a direct reduction of the carrying amount of the related debt. Debt issuance costs are amortized over the maturity period of the related debt instrument using the effective interest method. Equity-Based Payments to Non-Employees Equity-based payments to non-employees are measured at fair value on the grant date per ASU No. 2018-07, Improvements to Nonemployee Share-Based Payment Accounting. 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 are translated to U.S. dollars, which is the functional currency, at period end exchange rates. Income and expense items are translated at average rates of exchange prevailing during the periods presented. Gains and losses from translation adjustments are accumulated in a separate component of stockholders’ equity. Goodwill and Intangible Assets 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 December 31, 2021 related to goodwill. Intangible assets subject to amortization consist of in patents, process research and development and licenses, reported at the fair value at date of the acquisition less accumulated amortization. Amortization expense is provided using the straight-line method over their estimated useful lives. The carrying amounts of finite-lived intangible assets are evaluated for recoverability whenever events or changes in circumstances indicate that the Company may be unable to recover the asset’s carrying amount. Given changes in the projected usage of the patents, the Company recognized impairment charges of approximately $2.4 million at December 31, 2021. 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 December 31, 2021. Income Taxes Income taxes are recorded in accordance with ASC 740, Accounting for Income Taxes (“ASC 740”), which provides for deferred taxes using an asset and liability approach. The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. The Company determines its deferred tax assets and liabilities based on differences between financial reporting and tax bases of assets and liabilities, which are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Valuation allowances are provided if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company accounts for uncertain tax positions in accordance with the provisions of ASC 740. When uncertain tax positions exist, the Company recognizes the tax benefit of tax positions to the extent that the benefit will more likely than not be realized. The determination as to whether the tax benefit will more likely than not be realized is based upon the technical merits of the tax position as well as consideration of the available facts and circumstances. At December 31, 2021 and 2020, the Company does not have any significant uncertain tax positions. Leases Leases are recorded on the balance sheet as right of use assets and lease obligations. Loss Per Share Basic loss per share (“EPS”) is computed by dividing the loss attributable to common shareholders by the weighted average number of shares of Common Stock outstanding. Diluted EPS reflects the potential dilution that could occur from shares of Common Stock issuable through the exercise or conversion of stock options, restricted stock awards, warrants and convertible securities. In certain circumstances, the conversion of options is excluded from diluted EPS if the effect of such inclusion would be anti-dilutive. The dilutive effect of stock options is determined using the treasury stock method. Stock options to purchase shares of Common Stock of the Company during fiscal 2021 and 2020 were not included in the computation of diluted EPS because the Company has incurred a loss for the years ended December 31, 2021 and 2020 and the effect would be anti-dilutive. 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, amortization of intangible assets related to the acquisition of adrulipase and research and development costs related to niclosamide. Research and Development – Intellectual Property Acquired On December 31, 2020, the Company entered into a license agreement (the “FWB License Agreement”) with FWB, pursuant to which FWB granted the Company an exclusive license to certain patents and patent applications related to a proprietary formulation of niclosamide for use in the fields of ICI-AC and COVID-19 GI infections. 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 was accounted for as an asset acquisition and initial liabilities of approximately $13.3 million in connection with the license acquisition were recorded as research and development expense, because it was determined to have no alternative future uses and therefore no separate economic value, which included cash payments totaling approximately $10.3 million and the issuance of approximately $3.0 million worth of preferred stock. Upon consummation of the Merger (as defined below) on September 13, 2021, the FWB License Agreement was effectively canceled. On September 13, 2021, the Company completed its acquisition of FWB, which the Company concluded should be accounted for as an asset acquisition rather than a business combination under ASC 805, Business Combinations. The merger was accounted for as an asset acquisition because substantially all the fair value of the assets being acquired are concentrated in a single asset – intellectual property, which does not constitute a business. The former FWB stockholders are also entitled to (i) up to $207.0 million of cash milestone payments contingent upon the achievement of specified development, regulatory and sales goals for the use of the acquired assets, and (ii) certain revenue-sharing. During the year ended December 31, 2021, the Company achieved one development milestone pursuant to the FWB License Agreement totaling $1.0 million, which was accrued and expensed in research and development. During the year ended December 31, 2021, the Company achieved one development milestone pursuant to the Merger Agreement totaling $2.0 million, which was expensed in research and development. 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. 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 and Board members in accordance with ASC Topic 718, Compensation—Stock Compensation (“ASC 718”). ASC 718 requires all stock-based payments to employees 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. 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 January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other, Simplifying the Accounting for Goodwill Impairment. ASU 2017-04 removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance will remain largely unchanged. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. This new guidance will be applied prospectively and is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. This ASU, which the Company adopted as of January 1, 2020, did not have a material effect on the Company’s consolidated financial statements. In August 2020, the FASB issued accounting pronouncement (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. The Company is currently evaluating the impact of this ASU on the consolidated financial statements.

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 December 31, 2021 related to goodwill.

Intangible assets subject to amortization consist of in patents, process research and development and licenses, reported at the fair value at date of the acquisition less accumulated amortization. Amortization expense is provided using the straight-line method over their estimated useful lives. The carrying amounts of finite-lived intangible assets are evaluated for recoverability whenever events or changes in circumstances indicate that the Company may be unable to recover the asset’s carrying amount.

The determination as to whether the tax benefit will more likely than not be realized is based upon the technical merits of the tax position as well as consideration of the available facts and circumstances. At December 31, 2021 and 2020, the Company does not have any significant uncertain tax positions.

Basic loss per share (“EPS”) is computed by dividing the loss attributable to common shareholders by the weighted average number of shares of Common Stock outstanding. Diluted EPS reflects the potential dilution that could occur from shares of Common Stock issuable through the exercise or conversion of stock options, restricted stock awards, warrants and convertible securities. In certain circumstances, the conversion of options is excluded from diluted EPS if the effect of such inclusion would be anti-dilutive.

The dilutive effect of stock options is determined using the treasury stock method. Stock options to purchase shares of Common Stock of the Company during fiscal 2021 and 2020 were not included in the computation of diluted EPS because the Company has incurred a loss for the years ended December 31, 2021 and 2020 and the effect would be anti-dilutive.
