Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Organization and Description of Business | 1. Organization and de scription of business Coya Therapeutics, Inc. (“Coya”, or the “Company”) is a clinical-stage biotechnology company focused on developing proprietary new therapies to enhance the function of Regulatory T cells (“Tregs”). Coya’s initial developmental programs are focused on neurodegenerative, chronic inflammatory, autoimmune, and metabolic diseases of high unmet medical need. Going Concern and Liquidity The Company has incurred losses since inception, negative cash flows from operations and has an accumulated deficit of $62.0 million as of December 31, 2025. The Company anticipates incurring additional losses until such time, if ever, that it can generate significant sales of its product candidates currently in development. Substantial additional financing will be needed by the Company to fund its operations and to commercially develop its product candidates. No assurance can be given that any such financing will be available when needed or that the Company’s research and development efforts will be successful. The Company follows the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 205-40, Presentation of Financial Statements—Going Concern, which requires management to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for one year after the date that the financial statements are issued (or when applicable, one year after the date that the financial statements are available to be issued). The Company's cash and cash equivalents of $46.8 million as of December 31, 2025, together with the $11.1 million in gross proceeds from the January 2026 Offering (defined below), is expected to enable the Company to fund its operating expenses and capital expenditure requirements for at least one year after the financial statements are issued, at which time the Company will need to secure additional funding. If the Company is unable to obtain additional financing, the lack of liquidity could have a material adverse effect on the Company’s future prospects. The accompanying financial statements have been prepared on a going-concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The financial statements do not include any adjustments related to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty. Risks and uncertainties The Company is subject to a number of risks associated with companies at a similar stage, including dependence on key individuals, competition from similar products and larger companies, volatility of the industry, ability to obtain adequate financing to support growth, the ability to attract and retain additional qualified personnel to manage the anticipated growth of the Company, and general economic conditions.
