Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	Description of Business Overview Lisata Therapeutics, Inc. (together with its subsidiaries, the “Company”) is a clinical-stage pharmaceutical company dedicated to the discovery, development, and commercialization of innovative therapies for the treatment of solid tumors and other major diseases. The Company's investigational product, certepetide (formerly known as LSTA1 or CEND-1), is designed to activate a novel uptake pathway (the C-end rule active transport mechanism) that allows co-administered or tethered (i.e., molecularly bound) anti-cancer drugs to target and penetrate solid tumors more effectively. Certepetide actuates this active transport system in a tumor-specific manner, resulting in systemically co-administered anti-cancer drugs more efficiently penetrating and accumulating in the tumor, while normal tissues are expected to remain unaffected. Certepetide has also been shown to modify the tumor microenvironment (“TME”) by reducing T-regulatory cells and augmenting cytotoxic T cells, thereby making tumors more susceptible to immunotherapies while also inhibiting the metastatic cascade (i.e., the spread of cancer to other parts of the body). The Company, its collaborators and other researchers have amassed and continue to amass significant non-clinical data demonstrating enhanced delivery of a range of existing and emerging anti-cancer therapies, including chemotherapeutics, immunotherapies, and RNA-based therapeutics. In addition, certain preclinical data using certepetide in combination with antibody drug conjugates (ADCs) has been generated as part of the Company’s research collaboration with Catalent. These data were presented recently at the 16th Annual World ADC San Diego Conference on November 4, 2025. To date, certepetide has also demonstrated favorable safety, tolerability and activity in completed and ongoing clinical trials designed to enhance delivery of standard-of-care chemotherapy, with and without added immunotherapy, for pancreatic cancer. The Company is exploring certepetide as a means to enable a variety of therapeutic modalities to treat a range of solid tumors more effectively. Currently, certepetide is the subject of several Phase 2 clinical studies globally in a variety of solid tumor types, including metastatic pancreatic ductal adenocarcinoma (mPDAC), cholangiocarcinoma, appendiceal cancer, colon cancer and glioblastoma multiforme in combination with a variety of anti-cancer regimens. The Company's leadership team has amassed many decades of collective biopharmaceutical and pharmaceutical product development experience across a variety of therapeutic categories and at all stages of development, ranging from preclinical through to product registration and launch. The Company's goal is to develop and commercialize products that address important unmet medical needs. The Company has a history of net operating losses and negative cash flows from its operating activities, and has cash, cash equivalents and marketable securities of approximately $19.0 million as of September 30, 2025. The Company anticipates incurring additional losses until such time, if ever, that it can generate significant revenues from its products currently in development. To manage capital for operating needs in the short-term, as previously disclosed, the Company has delayed commencement of certain readiness activities for its planned Phase 3 study in metastatic pancreatic ductal adenocarcinoma (mPDAC), particularly those related to chemistry, manufacturing and controls (“CMC”). The Company’s ongoing trials continue to progress as planned. The Company also continued to identify certain operating efficiencies which had a positive impact on the cash flow forecast. The Company believes that, as a result, it currently has sufficient cash to meet its funding requirements over the next 12 months. To meet our long-term liquidity needs, the Company expects that it will need additional financing by the end of 2026, which could result in additional potential issuances of debt or equity securities in public or private financings, partnerships and/or collaborations and/or sale of assets. Basis of Presentation The accompanying unaudited Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the SEC for interim financial information. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, the accompanying Consolidated Financial Statements of the Company and its subsidiaries, which are unaudited, include all normal and recurring adjustments considered necessary to present fairly the Company’s financial position as of September 30, 2025, and the results of its operations and its cash flows for the periods presented. The unaudited consolidated financial statements herein should be read together with the historical consolidated financial statements of the Company for the years ended December 31, 2024 and 2023 included in our 2024 Form 10-K. Operating results for the three and nine months ended September 30, 2025 are not necessarily indicative of the results that may be expected for the year ending December 31, 2025. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements. Estimates also affect the reported amounts of expenses during the reporting period. The Company bases its estimates on historical experience and other assumptions believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. The Company makes critical estimates and assumptions in determining stock-based awards values. Accordingly, actual results could differ from those estimates and assumptions. Segment Information The Company operates as one operating segment, the research and development of its investigational drug product. The Company's Chief Operating Decision Maker (“CODM”) is its Chief Executive Officer, who manages the business on a consolidated basis. Principles of Consolidation The Consolidated Financial Statements include the accounts of Lisata Therapeutics, Inc. and its wholly owned and majority owned subsidiaries and affiliates. All intercompany activities have been eliminated in consolidation. Foreign Currency Remeasurement The Company’s reporting currency is the U.S. Dollar. The functional currency of Lisata Therapeutics Australia Pty Ltd., which is a foreign subsidiary of the Company, is the Australian Dollar. The assets and liabilities of Lisata Therapeutics Australia Pty Ltd. are translated into U.S. Dollars at the exchange rates in effect at each balance sheet date, and the results of operations are translated using the average exchange rates prevailing throughout the reporting period. Adjustments resulting from translating foreign functional currency financial statements into U.S. Dollars are included in the foreign currency translation adjustment, a component of accumulated other comprehensive income (loss) in stockholders' equity.
