Sep. 30, 2023
Accounting Policies [Abstract] |
Basis of Accounting, Policy [Policy Text Block] | Basis of Presentation The accompanying Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. They do not include all information and notes required by GAAP for complete financial statements. However, except as disclosed herein, there has been no material changes in the information disclosed in the Notes to Consolidated Financial Statements included in the Annual Report on Form 10-K of the Company for the year ended December 31, 2022. The year-end Condensed Consolidated Balance Sheet presented in this report was derived from audited consolidated financial statements but does not include all disclosures required by GAAP. All amounts in the Condensed Consolidated Financial Statements and the notes thereto have been presented in thousands, except for par value and other per share data. In the opinion of management, all adjustments (including normal recurring accruals) considered necessary for a fair presentation have been included and have been prepared on the same basis as the annual consolidated financial statements. Operating results for the nine months ended September 30, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023.
Reclassification, Comparability Adjustment [Policy Text Block] | Reclassification Interest income has been reclassified from other expense, net to conform to the current year presentation.
Use of Estimates, Policy [Policy Text Block] | Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates.
Segment Reporting, Policy [Policy Text Block] | Segments The Company operates as a single segment. Operating segments are identified as the components of an enterprise for which separate discrete financial information is available for evaluation by the chief operating decision maker in making decisions regarding resource allocation and in assessing performance. To date, the Company's chief operating decision maker has made such decisions and assessed performance at the Company-level as a single segment.
Cash and Cash Equivalents, Policy [Policy Text Block] | Cash and Cash Equivalents Cash and cash equivalents include unrestricted cash and all highly liquid instruments with maturities of three months or less at the date of purchase.
Equity Securities without Readily Determinable Fair Value [Policy Text Block] | Investments in Equity Securities The Company currently has one investment in non-marketable securities. This investment does not have a readily determinable fair value, so the Company has elected to measure the investment at cost in accordance with Accounting Standards Codification (ASC) 321 – Equity. At each reporting period, the Company performs an assessment to determine if it still qualifies for this measurement alternative. The Company considers qualitative impairment factors in determining if there are any signs of impairment. Once a decline in fair value is determined, an impairment charge is recorded to Impairment charge on investment in equity securities in the Condensed Consolidated Statement of Operations and Comprehensive Loss and a new basis in the investment is established. If market, industry, and/or investee conditions deteriorate, the Company may incur future impairments. Refer to Note 4.
Other Assets [Policy Text Block] | Other Assets Other assets consist primarily of prepaid clinical and non-clinical costs which are long term in nature.
Fair Value Measurement, Policy [Policy Text Block] | Fair Value Measurements The Company records financial assets and liabilities measured on a recurring and non-recurring basis, as well as all non-financial assets and liabilities subject to fair value measurement at the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. The accounting guidance establishes a hierarchy for inputs used in measuring fair value that minimizes the use of unobservable inputs by requiring the use of observable market data when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on active market data. Unobservable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability based on the best information available in the circumstances. The fair value hierarchy is broken down into the three input levels summarized below: ● Level 1 —Valuations are based on quoted prices in active markets for identical assets or liabilities and readily accessible by us at the reporting date. ● Level 2 —Valuations based on inputs other than the quoted prices in active markets that are observable either directly or indirectly in active markets. ● Level 3 —Valuations based on unobservable inputs in which there are little or no market data, which require the Company to develop its own assumptions. The carrying amounts reflected in the accompanying Condensed Consolidated Balance Sheets for cash and cash equivalents, restricted cash, prepaid expenses, research and development rebate receivable, other current assets, accounts payable, accrued expenses, payroll liabilities and other current liabilities approximate their fair values due to their short-term nature. Refer to Note 10.
Research and Development Expense, Policy [Policy Text Block] | Research and Development Research and development (R&D) costs are generally expensed as incurred. R&D expenses include, for example, manufacturing expenses for the Company's drugs under development, expenses associated with preclinical studies, clinical trials and associated salaries, bonuses, stock-based compensation and benefits. The Company has entered into various research and development contracts with research institutions, clinical research organizations (CROs), clinical manufacturing organizations (CMOs) and other companies. Payments for these activities are based on the terms of the individual agreements, which may differ from the timing of costs incurred, and payments made in advance of performance are reflected in the Condensed Consolidated Balance Sheets as prepaid expenses. The Company records accruals for estimated costs incurred for ongoing research and development activities as reflected in the Condensed Consolidated Balance Sheets as accrued expenses. When evaluating the adequacy of the accrued expenses, the Company analyzes progress of the services, including the phase or completion of events, invoices received and contracted costs. Significant judgments and estimates may be used in determining the prepaid expense or accrued expense balances at the end of any reporting period. Actual results could differ from the Company’s estimates. R&D expenses also include an allocation of the CEO's salary and related benefits, including bonus and non-cash stock-based compensation expense, based on an estimate of his total hours spent on R&D activities. The Company's CEO is involved in the development of the Company's drug candidates and oversight of the related clinical trial activity and also acts as the Company's chief medical officer.
Share-Based Payment Arrangement [Policy Text Block] | Stock-based Payments The Company measures and recognizes compensation expense for all stock-based payment awards made to employees, officers, non-employee directors, and other key persons providing services to the Company, currently limited to stock options. Stock compensation expense is based on the estimated grant date fair value and is recognized as an expense over the requisite service period. The Company has made a policy election to recognize forfeitures when they occur. The fair value of each stock option grant is estimated using the Black-Scholes option-pricing model, which requires assumptions regarding the expected volatility of the stock options, the expected life of the options, an expectation regarding future dividends on the Company’s common stock, and an estimate of the appropriate risk-free interest rate. The Company’s expected common stock price volatility assumption is based upon the historical volatility of its stock price. The Company has elected the simplified method for the expected life assumption for stock option grants, which averages the contractual term of the options of 10 years with the vesting term, typically one to four years, as the Company does not have sufficient history of option exercise experience. The dividend yield assumption of zero is based upon the fact that the Company has never paid cash dividends and presently has no intention of paying cash dividends in the future. The risk-free interest rate used for each grant was based upon prevailing short-term interest rates over the expected life of the options as of the grant date.
Foreign Currency Transactions and Translations Policy [Policy Text Block] | Foreign Currency Translation and Transactions The majority of the Company's operations occur in entities that have the U.S. dollar as their functional currency. Subsidiary assets and liabilities translated into U.S. dollars at rates of exchange in effect at the end of the period. Expense amounts are translated using the average exchange rates for the period.
