| Accounting Policies [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Basis of Presentation | Basis of Presentation The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and pursuant to rules and regulations of the Securities and Exchange Commission for interim financial information. 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 months ended June 30, 2026 are not necessarily indicative of the results expected for the full fiscal year or any subsequent interim period. The unaudited condensed balance sheet as of June 30, 2026 has been derived from the financial statements as of that date but does not include all disclosures required by GAAP for complete financial statements. As all of the disclosures required by GAAP for complete financial statements are not included herein, these unaudited condensed financial statements and the notes accompanying herein should be read in conjunction with the Company’s audited financial statements as of and for the years ended December 31, 2024 and 2025 included in the Company’s final prospectus dated August 7, 2026 related to its IPO filed pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended. Any reference in these notes to applicable guidance is meant to refer to GAAP as found in the ASC and Accounting Standards Updates (“ASU”) promulgated by the Financial Accounting Standards Board (“FASB”). |

| Unaudited Condensed Consolidated Interim Financial Information | Unaudited Condensed Interim Financial Information The unaudited condensed balance sheet as of June 30, 2026, the unaudited condensed statements of operations for the three and six months ended June 30, 2026 and 2025, the unaudited condensed statements of convertible preferred stock and stockholders’ deficit for the three and six months ended June 30, 2026 and 2025, and the unaudited condensed statements of cash flows for the six months ended June 30, 2026 and 2025 are unaudited. These unaudited condensed financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments necessary to present fairly the Company’s financial position, results of operations, and cash flows for the interim period presented. The financial data and the other financial information contained in these notes to the unaudited condensed financial statements related to the three and six months ended June 30, 2026 and 2025 are also unaudited. The condensed results of operations for the three and six months ended June 30, 2026 are not necessarily indicative of the results to be expected for the year ending December 31, 2026 or for any other future annual or interim period. |

| Use of Estimates | Use of Estimates The preparation of the Company’s unaudited condensed financial statements requires the Company to make estimates and assumptions that impact the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities in the unaudited condensed financial statements and accompanying notes. Such estimates include the estimated incremental borrowing rate for the determination of the Company’s operating lease right-of-use assets, valuation of stock-based awards, fair value of common stock prior to the Company's IPO, and the accrual of research and development expenses. Management evaluates its estimates on an ongoing basis. Although estimates are based on the Company’s historical experience, knowledge of current events, and actions it may undertake in the future, actual results may ultimately materially differ from these estimates and assumptions. |

| Common Stock Valuation | Common Stock Valuation Due to the absence of an active market for the Company’s common stock, the Company utilized methodologies, approaches and assumptions consistent with the American Institute of Certified Public Accountants’ Audit and Accounting Practice Guide: Valuation of Privately-Held Company Equity Securities Issued as Compensation to estimate the fair value of its common stock prior to its IPO. In determining the exercise prices for options granted, the Company has considered the fair value of the common stock as of the grant date. The estimated fair value of the common stock has been determined based upon a variety of factors, including: • the prices at which the Company sold shares of its convertible preferred stock and the superior rights, preferences and privileges of the convertible preferred stock relative to the Company’s common stock at the time of each grant; • the progress of the Company’s research and development programs; • the Company’s stage of development and its business strategy; • external market conditions affecting the biotechnology industry and trends within the biotechnology industry; • the Company’s financial position, including cash on hand, and its historical and forecasted performance and operating results; • the lack of an active public market for the Company’s common stock and its convertible preferred stock; • the likelihood of achieving a liquidity event, such as an initial public offering or sale of the Company in light of prevailing market conditions; and • the analysis of IPOs and the valuations and market performance of similar companies in the biotechnology industry. Based on the Company’s early stage of development and other relevant factors, options granted prior to February 11, 2026, were valued using an option pricing method (“OPM”) as an OPM was the most appropriate method for allocating the enterprise value to determine the estimated fair value of the common stock. For options granted after February 11, 2026, the Company determined that a hybrid method that combines both OPM and probability-weighted expected return method (“PWERM”) was the most appropriate method to determine the estimated fair value of the Company’s common stock. Significant changes to the key assumptions underlying the factors used could result in different fair values of common stock at each valuation date. |

| Deferred Offering Costs | Deferred Offering Costs The Company capitalizes costs that are directly associated with in-process equity financings until such financings are consummated, at which time such costs are recorded against the gross proceeds of the offering. Should an in-process equity financing be abandoned, the deferred offering costs will be expensed immediately as a charge to operating expenses in the statements of operations. As of June 30, 2026, the Company had deferred offering costs of $3.0 million, recorded as a component of prepaid expenses and other current assets. There were no deferred offering costs as of December 31, 2025. |

| Net Loss per Share | Net Loss per Share Basic net loss per share is calculated by dividing the net loss by the weighted-average number of common shares outstanding for the period. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock and common stock equivalents outstanding for the period. The Company has excluded 102,002 and 51,283 weighted-average shares subject to repurchase or forfeiture from the weighted-average number of shares of common stock outstanding for the three and six months ended June 30, 2026, respectively. Common stock equivalents are only included when their effect is dilutive. The Company’s potentially dilutive securities include outstanding convertible preferred stock, as well as outstanding stock options under the Company’s 2020 Equity Incentive Plan. Potentially dilutive securities have been excluded from the computation of diluted net loss per share as their inclusion would be anti-dilutive. For all periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding due to the Company’s net loss position. The following table summarizes the outstanding potentially dilutive securities that have been excluded from the calculation of diluted net loss per share because their inclusion in the calculation would be anti-dilutive:

| Emerging Growth Company Status | Emerging Growth Company Status The Company is an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act (the “JOBS Act”), and may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies. The Company may take advantage of these exemptions up until the last day of the fiscal year following the fifth anniversary of an offering or such earlier time that the Company is no longer an “emerging growth company.” Section 107 of the JOBS Act provides that an “emerging growth company” can take advantage of the extended transition period afforded by the JOBS Act for the implementation of new or revised accounting standards. The Company has elected to use the extended transition period for complying with new or revised accounting standards and as a result of this election, its financial statements may not be comparable to companies that comply with public company effective dates. However, the Company may elect to early adopt any new or revised accounting standards whenever such early adoption is permitted for non-public companies. The Company may take advantage of these exemptions up until the time that it is no longer an emerging growth company. |

| Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements There were no significant updates not already disclosed in the Company’s audited financial statements for the years ended December 31, 2024 and 2025 to the recently issued accounting standards for the three months ended June 30, 2026. Although there are several other new accounting pronouncements issued by the FASB, the Company does not believe any of those accounting pronouncements have had or will have a material impact on its financial position or operating results. |
