Accounting Policies [Abstract]
Summary of significant accounting policies	2. Summary of significant accounting policies The Company’s significant accounting policies are disclosed in the audited consolidated financial statements and the notes thereto in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on February 28, 2025. Except as reflected below, there were no changes to the Company’s significant accounting policies as described in the Annual Report on Form 10-K. Reflected in this note are updates to accounting policies, including the impact of the adoption of new policies. Unaudited interim financial statements The accompanying unaudited condensed consolidated financial statements have been prepared by the Company in accordance with GAAP for interim financial reporting and as required by Regulation S-X, Rule 10-01. The unaudited condensed consolidated financial statements have been prepared on the same basis as the Company’s audited annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary to fairly state the Company’s financial position and the results of its operations and cash flows. The financial data and other information disclosed in these notes related to the three and nine months ended September 30, 2025 and 2024 are unaudited. The results for the three and nine months ended September 30, 2025 are not necessarily indicative of results to be expected for the year ending December 31, 2025, any other interim periods, or any future year or period. Use of estimates The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the condensed consolidated financial statements and accompanying notes. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, the recognition of research and development expenses, stock-based compensation expense, warrant liabilities and the valuation allowance for deferred tax assets. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. On an ongoing basis, management evaluates its estimates when there are changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates. Concentrations of credit risk Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash, cash equivalents, short-term and long-term marketable securities. Periodically, the Company maintains deposits in accredited financial institutions in excess of federally insured limits. The Company deposits its cash investments in financial institutions that it believes have high credit quality and has not experienced any losses on such accounts and does not believe it is exposed to any unusual credit risk beyond the normal credit risk associated with commercial banking relationships. At September 30, 2025, all of the Company’s cash, cash equivalents, short-term and long-term investments were held at three accredited financial institutions. Recently Adopted Accounting Pronouncements In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. Under ASU No. 2023-09, entities are required to uniformly classify and present greater disaggregation of information in the rate reconciliation and income taxes paid. ASU No. 2023-09 is intended to benefit investors by improving the transparency and decision usefulness of income tax disclosures. The new standard is effective for annual periods beginning after December 15, 2024. The Company adopted the ASU No. 2023-09 effective January 1, 2025. The adoption of this guidance did not have a material impact on the Company’s condensed consolidated financial statements and related disclosures. Recently Issued Accounting Standards Not Yet Adopted In November 2024 and January 2025, the FASB issued ASU No. 2024-03 and ASU No. 2025-01, Comprehensive Income - Expense Disaggregation Disclosures, which will improve the disclosures about a public business entity’s expenses and address requests from investors for more detailed information about the types of expenses in commonly presented expense captions such as cost of sales, selling, general and administrative, and research and development. The amendments are effective for fiscal years beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted for annual financial statements that have not yet been issued or made available. The amendments should be applied on either (1) prospectively to financial statements issued for reporting periods after the effective date or (2) retrospectively to any or all prior periods presented in the financial statements. The Company is currently evaluating the provisions of the amendments and the effect on its future condensed consolidated financial statements.
