| Business, basis of presentation, new accounting standards and summary of significant accounting policies | |
| Basis of presentation | A.Basis of presentation We prepared the condensed consolidated financial statements following the requirements of the United States (“U.S.”) Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain notes or other financial information that are normally required by accounting principles generally accepted in the U.S. (“GAAP”) for complete financial statements can be condensed or omitted. However, except as disclosed herein, there has been no material change in the information disclosed in the notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (“2025 Form 10-K”). Revenues, expenses, assets, liabilities, and equities can vary during each quarter of the year. Therefore, the results and trends in these condensed consolidated financial statements may not be representative of those for the full year. In our opinion, all adjustments necessary for a fair statement of the condensed consolidated financial statements, which are of a normal and recurring nature, have been made for the interim periods reported. The information included in the condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes included in our 2025 Form 10-K. Certain amounts in the condensed consolidated financial statements and accompanying notes may not add up due to rounding, and all percentages have been calculated using unrounded amounts. |
| New accounting standards | B.New accounting standards Adoption of new accounting standards New accounting standards or accounting standards updates were assessed and determined to be either not applicable or did not have a material impact on our consolidated financial statements or processes. Accounting standards issued but not yet adopted In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses to improve financial reporting by requiring that public business entities disclose additional information about specific expense categories in the notes to the consolidated financial statements at interim and annual reporting periods. The amendments in this ASU do not change or remove current expense disclosure requirements; however, the amendments affect where such information appears in the notes to the consolidated financial statements because entities are required to include certain current disclosures in the same tabular format disclosure as the other disaggregation requirements in the amendments. In January 2025, the FASB issued ASU 2025-01, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date. This ASU is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within annual reporting period beginning after December 15, 2027. Early adoption is permitted. We continue to evaluate the impact of adopting this ASU to our notes to the consolidated financial statements and processes. Other recently issued accounting standards not yet adopted by us are not expected, upon adoption, to have a material impact on our consolidated financial statements. |
| Estimates and assumptions | C.Estimates and assumptions The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, expenses, and related disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of expenses during the reporting period. The most significant estimates in our condensed consolidated financial statements relate to clinical trial costs and accruals, classification of warrants as derivative liability or equity, and the fair value of stock-based compensation and warrants. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from those estimates. Changes in estimates are reflected in reported results in the period in which they become known. |
| Financial Instruments with Characteristics of Both Liabilities and Equity | Financial Instruments with Characteristics of Both Liabilities and Equity We account for issued warrants either as a liability or equity in accordance with Accounting Standard Codification (“ASC”) 480-10, Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity, and ASC 815-40, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock. Under ASC 480-10, warrants are considered a liability if they are mandatorily redeemable and they require settlement in cash, other assets, or a variable number of shares. If warrants do not meet liability classification under ASC 480-10, we consider the requirements of ASC 815-40 to determine whether the warrants should be classified as a liability or as equity. Under ASC 815-40, contracts that may require settlement for cash are liabilities, regardless of the probability of the occurrence of the triggering event. Liability-classified warrants are measured at fair value on the issuance date and at the end of each reporting period. Any change in the fair value of the warrants after the issuance date is recorded in other expense, net in the consolidated statements of operations as a gain or loss. If warrants do not require liability classification under ASC 815-40, in order to conclude warrants should be classified as equity, we assess whether the warrants are indexed to its common stock and whether the warrants are classified as equity under ASC 815-40 or under another applicable GAAP standard. Equity-classified warrants are accounted for at fair value on the issuance date with no changes in fair value recognized after the issuance date. |
