Accounting Policies [Abstract] |
Liquidity | Liquidity From inception and through September 30, 2025, the Company has devoted substantially all of its efforts to drug discovery and development. The Company has a limited operating history, has incurred operating losses since inception and expects to continue to incur significant operating losses for the foreseeable future. The Company incurred net losses of $64.9 million and $61.9 million for the nine months ended September 30, 2025 and the year ended December 31, 2024, respectively. As of September 30, 2025, the Company has an accumulated deficit of $202.4 million and cash, cash equivalents and marketable securities of $391.7 million. Based on the Company’s current business plan, management believes that existing cash and cash equivalents and marketable securities will be sufficient to fund the Company’s obligations for at least 12 months from the date of issuance of these condensed financial statements.
Basis of presentation | Basis of presentation The accompanying unaudited condensed financial statements as of September 30, 2025 and for the three and nine months ended September 30, 2025 and 2024 have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") for interim financial information and pursuant to Article 10 of Regulation of the Securities Act of 1933, as amended. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. These unaudited condensed financial statements include only normal and recurring adjustments that the Company believes are necessary to fairly state the Company’s financial position and the results of its operations and cash flows. The results for the three and nine months ended September 30, 2025 are not necessarily indicative of the results expected for the full fiscal year or any subsequent interim period. The condensed balance sheet at December 31, 2024 has been derived from the audited financial statements at that date but does not include all disclosures required by U.S. GAAP for complete financial statements. Because all of the disclosures required by U.S. GAAP for complete financial statements are not included herein, these unaudited condensed financial statements and the notes accompanying them should be read in conjunction with the Company’s audited financial statements for the year ended December 31, 2024 included in the Company's Annual Report on Form 10-K as filed with the SEC on March 17, 2025 ("2024 Annual Report").
Deferred Offering Costs | Deferred offering costs The Company capitalizes as deferred offering costs all direct and incremental legal, professional, accounting and other third-party fees incurred in connection with the September 2025 Offering and IPO. The deferred offering costs related to the September 2025 Offering and IPO were each offset against the September 2025 Offering proceeds and IPO proceeds, respectively, upon the consummation of the applicable offerings. As of September 30, 2025, $0.3 million of deferred offering costs were included in accounts payable and accrued expenses in the accompanying balance sheets. As of September 30, 2024, $0.3 million of deferred offering costs were included in accounts payable and accrued expenses in the accompanying balance sheets.
Recently Issued Accounting Pronouncements | Recently issued accounting pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board ("FASB") or other standard-setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on the accompanying financial statements and disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes: Improvements to Income Tax Disclosures (Topic 740), which establishes incremental disaggregation of income tax disclosures pertaining to the effective tax rate reconciliation and income taxes paid. This new standard is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The standard should be applied prospectively to financial statements issued for periods after the effective date of this ASU with the option to apply it retrospectively. The Company intends to adopt this standard in its Annual Report on Form 10-K for the year ending December 31, 2025 and is currently assessing the impact ASU 2023-09 (Topic 740) will have on its financial statements, including the footnote disclosures. 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, which is intended to provide more detailed information about specified categories of expenses (purchases of inventory, employee compensation, depreciation and amortization) included in certain expense captions presented on the face of our income statements. This new standard is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The amendments may be applied either (1) prospectively to financial statements issued for periods after the effective date of this ASU or (2) retrospectively to all prior periods presented in the financial statements. The Company is currently assessing the impact ASU 2024-03 will have on its financial statements, including the footnote disclosures. Recently enacted legislation In July 2025, the One Big Beautiful Bill Act (“OBBBA”) was signed into law, which includes significant provisions modifying the U.S. tax framework. The Company is currently assessing the impact these legislative changes will have on its financial statements, including the footnote disclosures.
