Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES There have been no significant changes from the significant accounting policies and estimates disclosed in Note 2 of the "Notes to Financial Statements" in the audited financial statements for the year ended December 31, 2025 and notes thereto, included in the 2025 Annual Report, except as noted below. Cash, Cash Equivalents and Restricted Cash The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents. As of June 30, 2026 and December 31, 2025, cash and cash equivalents consisted primarily of checking and savings deposits, money market fund holdings, and commercial paper. The Company maintains certain cash balances that are legally or contractually restricted as to withdrawal or use. These balances are classified as restricted cash and are included in prepaid expenses and other current assets or other assets in the accompanying balance sheets, depending on the nature and timing of the restrictions. The Company's restricted cash relates to amounts held under a letter of credit in connection with a lease agreement. As of June 30, 2026, $0.2 million of restricted cash is included in other assets in the accompanying June 30, 2026 balance sheet. The Company did not have any restricted cash balances at December 31, 2025. For purposes of the condensed statements of cash flows, cash, cash equivalents and restricted cash are included in the beginning of period and end of period total cash, cash equivalents and restricted cash balances. 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 March 2026 Sales Agreement, the February 2026 ATM Offering and the September 2025 Offering. The deferred offering costs related to the February 2026 ATM Offering and the September 2025 Offering were each offset against the February 2026 ATM Offering proceeds and the September 2025 Offering proceeds, respectively, upon the consummation of the applicable offerings. As of June 30, 2026, $0.4 million of deferred offering costs are included in other assets in the accompanying June 30, 2026 balance sheet, of which less than $0.1 million are included in accounts payable and accrued expenses. As of December 31, 2025, the Company had $0.3 million of deferred offering costs included in other assets, of which $0.1 million were included in accounts payable and accrued expenses, in the accompanying balance sheets. 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 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.
