Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business	Nature of Business Ocugen, Inc., together with its wholly owned subsidiaries ("Ocugen" or the "Company"), is a biotechnology company focused on discovering, developing, and commercializing novel gene and cell therapies, biologics and vaccines that improve health and offer hope for patients across the globe. The Company is headquartered in Malvern, Pennsylvania, and manages its business as one operating segment. Refer to Note 15 for additional information. Going Concern The Company has incurred recurring net losses since inception and has funded its operations to date through the sale of common stock, warrants to purchase common stock, the issuance of convertible notes and debt, and grant proceeds. The Company incurred net losses of approximately $54.1 million and $63.1 million for the years ended December 31, 2024 and 2023, respectively. As of December 31, 2024, the Company had an accumulated deficit of $340.2 million and cash totaling $58.5 million. This amount will not be sufficient to fund the Company's operations over the next 12 months after the date that the consolidated financial statements are issued. Due to the inherent uncertainty involved in making estimates and the risks associated with the research, development, and commercialization of biotechnology products, the Company may have based this estimate on assumptions that may prove to be different than actuals, and the Company's operating plan may change as a result of many factors currently unknown to the Company. In November 2024, the Company entered into a debt financing transaction with Avenue Capital for net proceeds of $29.2 million, refer to Note 8 for additional information. Despite this additional funding, the Company is subject to risks and uncertainties frequently encountered by companies in its industry, and while the Company intends to continue its research, development, and commercialization efforts for its product candidates, the Company will require significant additional funding. If the Company is unable to obtain additional funding in the future and/or its research, development, and commercialization efforts require higher than anticipated capital, there will be a negative impact on the financial viability of the Company. The Company will continue to explore options to fund its operations through public and private placements of equity and/or debt, payments from potential strategic research and development arrangements, sales of assets, licensing and/or collaboration arrangements with pharmaceutical companies or other institutions, funding from the government, particularly for the development of the Company's novel inhaled mucosal vaccine platform, or funding from other third parties. Such financing and funding may not be available at all, or on terms that are favorable to the Company. While Company management believes that it has a plan to fund operations, its plan may not be successfully implemented. If we cannot obtain the necessary funding, we will need to delay, scale back, or eliminate some or all of our research and development programs and commercialization efforts; consider other various strategic alternatives, including a merger or sale; or cease operations. If we cannot expand our operations or otherwise capitalize on our business opportunities because we lack sufficient capital, our business, financial condition, and results of operations could be materially adversely affected. As a result of these factors, together with the anticipated continued spending that will be necessary to continue to research, develop, and commercialize the Company's product candidates, there is substantial doubt about the Company's ability to continue as a going concern within one year after the date that these consolidated financial statements are issued. The consolidated financial statements do not contain any adjustments that might result from the resolution of any of the above uncertainties.
