Basis of Presentation and Liquidity [Abstract]
Basis of Presentation and Liquidity	1. Basis of Presentation and Liquidity Galectin Therapeutics Inc. and subsidiaries (the “Company”) is a clinical stage biopharmaceutical company that is applying its leadership in galectin science and drug development to create new therapies for fibrotic disease and cancer. These candidates are based on the Company’s targeting of galectin proteins which are key mediators of biologic and pathologic function. These compounds also may have application for drugs to treat other diseases and chronic health conditions. The unaudited condensed consolidated financial statements as reported in this Quarterly Report on Form 10-Q reflect all adjustments which are, in the opinion of management, necessary to present fairly the financial position of the Company as of June 30, 2026 and the results of its operations for the three and six months ended June 30, 2026 and 2025 and its cash flows for the six months ended June 30, 2026 and 2025. All adjustments made to the interim financial statements include all those of a normal and recurring nature. Amounts presented in the condensed consolidated balance sheet as of December 31, 2025 are derived from the Company’s audited consolidated financial statements as of that date, but do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated through the date these financial statements are available to be issued. The results for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. The unaudited condensed consolidated financial statements of the Company should be read in conjunction with its Annual Report on Form 10-K for the year ended December 31, 2025. These consolidated financial statements have been prepared in accordance with US generally accepted accounting principles (GAAP) assuming the Company will continue as a going concern. The going concern assumption contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The Company has operated at a loss since its inception and has had no revenues. The Company anticipates that losses will continue for the foreseeable future. At June 30, 2026, the Company had $13.3 million of unrestricted cash and cash equivalents available to fund future operations. As of June 30, 2026, the Company has available borrowings under a line of credit in the amount of $10 million provided by our chairman, Richard Uihlein, (See Note 10). All of the Company’s borrowings and accrued interest under related party debt to its chairman are due to mature on June 30, 2027. The Company believes there is sufficient cash, including availability of the line of credit, to fund currently planned operations through June 2027. These factors raise substantial doubt about the Company’s ability to continue as a going concern for a period of 12 months from the issuance date of these financial statements. The ability of the Company to continue as a going concern is dependent on its ability to raise capital; however, the Company’s cash position may not be sufficient to support its daily operations after June 2027. To meet its future capital needs, the Company intends to raise additional capital through debt or equity financings, collaborations, partnerships or other strategic transactions. However, there can be no assurance that the Company will be able to complete any such transactions on acceptable terms or otherwise. The inability of the Company to obtain sufficient funds on acceptable terms when needed could have a material adverse effect on the Company’s business, results of operations and financial condition. The Company was founded in July 2000, was incorporated in the State of Nevada in January 2001 under the name “Pro-Pharmaceuticals, Inc.,” and changed its name to “Galectin Therapeutics Inc.” on May 26, 2011.
