Significant Accounting Policies [Text Block]

2. Basis of presentation, principles of consolidation, and significant accounting policies and liquidity 

Basis of Presentation – Condensed Consolidated Financial Information - The accompanying condensed consolidated financial statements and related notes have been prepared in accordance with accounting principles generally accepted in the U.S. (U.S. GAAP) for financial information, and in accordance with the rules and regulations of the U.S. Securities and Exchange Commission (SEC) with respect to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The condensed consolidated financial statements furnished reflect all normal adjustments, which are, in the opinion of management, necessary for a fair statement of results for the interim periods presented. Interim results are not necessarily indicative of the results for the full year. These condensed consolidated financial statements should be read in conjunction with the audited financial statements of the Company as of  December 31, 2022 and for the year then ended, including the notes thereto contained in the Form 10-K filed with the SEC on March 22, 2023.

Principles of Consolidation - The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Any reference in these notes to applicable guidance is meant to refer to U.S. GAAP. The Company views its operations and manages its business in one operating segment. All material long-lived assets of the Company reside in the U.S.

Significant Accounting Policies - The Company's significant accounting policies are described in Note 2, Basis of Presentation, principles of consolidation and significant accounting policies, to the consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2022. There have been no material changes to the significant accounting policies during the three months ended March 31, 2023.

Use of Estimates - The preparation of these condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. Management considers many factors in selecting appropriate financial accounting policies and controls, and in developing the estimates and assumptions that are used in the preparation of these financial statements. Management must apply significant judgment in this process. In addition, other factors may affect estimates, including expected business and operational changes, sensitivity and volatility associated with the assumptions used in developing estimates, and whether historical trends are expected to be representative of future trends. The estimation process often may yield a range of potentially reasonable estimates of the ultimate future outcomes and management must select an amount that falls within that range of reasonable estimates. This process may result in actual results differing materially from those estimated amounts used in the preparation of financial statements. Estimates are used in the following areas, among others: fair value estimates on intangible assets, warrants, and stock-based compensation expense, as well as accrued expenses and taxes. 

Liquidity and Financial Condition - The Company is an early stage company and has not generated any revenues to date. As such, the Company is subject to all of the risks associated with early stage companies. Since inception, the Company has incurred losses and negative cash flows from operating activities. For the three months ended March 31, 2023 and 2022, the Company incurred net losses of $7.9 million and $6.9 million, respectively, and had net cash flows used in operating activities of $6.0 million and $4.8 million, respectively. At March 31, 2023, the Company had an accumulated deficit of $109.8 million and cash and cash equivalents of $37.3 million. The Company expects its cash on hand as of March 31, 2023 will be sufficient to fund the Company's operations beyond the near term. Such projections are subject to changes in the Company’s internally funded preclinical and clinical activities, including unplanned preclinical and clinical activity. The Company does not expect to experience positive cash flows from operating activities in the near future and anticipates incurring operating losses for the next few years as it supports the development of its core technologies to the point of generating revenue, most likely via out-licensing, and continues to invest in research and development for additional applications of the Company's core technologies and potentially increase its pipeline of drug candidates. If the Company needs to raise additional capital in order to continue to execute its business plan, there is no assurance that additional financing will be available when needed or that management will be able to obtain financing on terms acceptable to the Company. A failure to raise sufficient capital could adversely impact the Company's ability to achieve its intended business objectives and meet its financial obligations as they become due and payable. In March 2022, the Company received a subpoena from the SEC requesting information and documents, including materials related to certain individuals (none of which are the Company's officers or directors) and entities, and materials related to the development of and statements regarding the Company's drug candidate for the treatment of COVID-19. The Company has received, and expects to continue to receive, periodic further requests from the SEC staff with respect to this matter. The Company is not aware of the specific nature of the underlying investigation by the SEC, and to the extent that this investigation relates to prior public disclosures that it has made, the Company believes in the accuracy and adequacy of such prior disclosures. The correspondence from the SEC transmitting the subpoena to the Company states that the SEC is trying to determine whether there have been any violations of federal securities laws, but that its investigation does not mean that the SEC has concluded that anyone has violated the law or that the SEC has a negative opinion of any person, entity, or security. The Company cannot predict when this matter will be resolved or what, if any, action the SEC may take following the conclusion of the investigation. During the three months ended March 31, 2023 and 2022, the Company has expensed approximately $0.5 million and $0.1 million, respectively, in related general and administrative fees and expenses.

Cash and Cash Equivalents - Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and cash equivalents. The Company maintains cash accounts principally at one financial institution in the U.S., which at times, may exceed the Federal Deposit Insurance Corporation’s limit. The Company has not experienced any losses from cash balances in excess of the insurance limit. The Company’s management does not believe the Company is exposed to significant credit risk at this time due to the financial condition of the financial institution where its cash is held. 

Fair Value of Financial Instruments - The Company's financial instruments consist primarily of non-trade receivables, accounts payable, accrued expenses and its warrant liability. The carrying amount of non-trade receivables, accounts payable, and accrued expenses approximates their fair value because of the short-term maturity of such.

The Company has categorized its assets and liabilities that are valued at fair value on a recurring basis into a three-level fair value hierarchy in accordance with U.S. GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities (Level 1) and lowest priority to unobservable inputs (Level 3).

Assets and liabilities recorded in the balance sheets at fair value are categorized based on a hierarchy of inputs as follows:

Level 1 – Unadjusted quoted prices in active markets of identical assets or liabilities.

Level 2 – Quoted prices for similar assets or liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument.

Level 3 – Unobservable inputs for the asset or liability.

The Company’s financial assets and liabilities recorded at fair value on a recurring basis include the fair value of warrant liability discussed in Note 3.

The following table provides the financial liabilities reported at fair value and measured on a recurring basis at March 31, 2023 and December 31, 2022 (table in thousands): 

Description	Fair Value		Level 1		Level 2		Level 3
Fair value of warrant liability as of March 31, 2023:	$	38	$	—	$	—	$	38
Fair value of warrant liability as of December 31, 2022:	$	77	$	—	$	—	$	77

The table below of Level 3 liabilities (table in thousands) begins with the valuation as of the beginning of the first quarter and then is adjusted for changes in fair value that occurred during the first quarter. The ending balance of the Level 3 financial instrument presented above represents the Company's best estimates and may not be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instruments. 

Three Months Ended March 31, 2023	Warrant Liability Long-Term
Balance, December 31, 2022	$	77
Change in fair value - net		(39	)
Balance, March 31, 2023	$	38

Loss Per Common Share - Basic net loss per common share is computed by dividing net loss available to common shareholders by the weighted-average number of common shares outstanding during the period. For purposes of this calculation, options to purchase common stock, restricted stock units subject to vesting and warrants to purchase common stock are considered to be common stock equivalents. Diluted net loss per common share is determined using the weighted-average number of common shares outstanding during the period, adjusted for the dilutive effect of common stock equivalents. In periods when losses are reported, the weighted-average number of common shares outstanding excludes common stock equivalents, because their inclusion would be anti-dilutive. For the three months ended March 31, 2023 and 2022, approximately 6.2 million and 4.8 million, respectively, of potentially dilutive shares were excluded from the computation of diluted earnings per share due to their anti-dilutive effect. 

Subsequent Events - The Company’s management reviewed all material events through the date of these unaudited condensed consolidated financial statements. See Note 7 - Subsequent Events. 

Recent Accounting Pronouncements - There are no recently issued accounting standards updates that are currently expected to have a material impact on the Company.
