Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	1. Organization and Basis of Presentation Description of Business Aardvark Therapeutics, Inc. (“Aardvark” or the “Company”) was incorporated in the State of Delaware on May 17, 2017 and its principal offices are located in San Diego, California. The Company is a clinical-stage biopharmaceutical company focused on developing novel, small-molecule therapeutics to activate innate homeostatic pathways for the treatment of metabolic diseases. The Company targets biological pathways associated with alleviating hunger. In October 2024, the Company incorporated a wholly-owned subsidiary, Artisan Therapeutics, Inc., in the State of Delaware and contributed certain assets to the new entity. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, Artisan Therapeutics, Inc., and have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”). All intercompany accounts and transactions have been eliminated in consolidation. Reverse Stock Split On February 5, 2025, the Company effected a one-for-8.474 reverse stock split of its common stock (the "Reverse Stock Split"). The par value and the authorized shares of the common stock were not adjusted as a result of the Reverse Stock Split. All issued and outstanding common stock and the conversion ratio of the redeemable convertible preferred stock have been retroactively adjusted to reflect the Reverse Stock Split for all periods presented. Liquidity As of December 31, 2025, the Company has devoted substantially all of its resources to organizing and staffing the Company, business planning, raising capital, discovering ARD-101, establishing and maintaining its intellectual property portfolio, conducting research, preclinical studies and clinical trials, manufacturing of ARD-101 and related raw materials, and providing general and administrative support for these operations. The Company does not have any products approved for sale and has not generated any revenue to date. In addition, the Company has a limited operating history, has incurred significant net losses and negative cash flows from operations since its inception and expects that its expenses and operating losses will increase substantially for the foreseeable future. As of December 31, 2025, the Company had an accumulated deficit of $115.9 million. The Company believes its cash, cash equivalents and short-term investments of $110.0 million as of December 31, 2025 will be sufficient for the Company to continue as a going concern for at least one year following the date that the consolidated financial statements are available to be issued. The Company will be required to raise additional capital and plans to finance its cash needs through public or private equity or debt financings or other capital sources, including potential collaborations, licenses and other similar arrangements. However, there can be no assurance that the Company will be able to obtain additional funding on acceptable terms, or at all. If the Company is not able to secure adequate additional funding, it may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible, and/or delay or reduce the scope of its planned development programs. Any of these actions could materially harm the Company’s business, results of operations and future prospects. Use of Estimates The preparation of the Company’s consolidated 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 consolidated 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 (“ROU”) assets, valuation of stock-based awards, 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.
