Basis of Presentation | 1. Basis of Presentation Galectin Therapeutics Inc. (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, skin diseases 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 10-K The Company has operated at a loss since its inception and has had no significant revenues. The Company anticipates that losses will continue for the foreseeable future. At September 30, 2019, the Company had $50.3 million of unrestricted cash and cash equivalents available to fund future operations. The Company believes there is sufficient cash, including availability of the line of credit (see Note 3), to fund currently planned operations at least through December 31, 2020. We expect that we will require more cash to fund our operations after December 31, 2020 and believe we will be able to obtain additional financing. The currently planned operations include estimated costs related to a planned clinical trial , The its next planned clinical estimated to be approximately $100 to $115 ; however are The Company was founded in July 2000, was incorporated in the State of Nevada in January 2001 under the name “Pro-Pharmaceuticals, Recently Adopted Accounting Standards The Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842), 2018-11, Leases (Topic 842): Targeted Improvements |

Line of Credit
Line of Credit | 9 Months Ended |
Sep. 30, 2019 | |
Line of Credit | 3. Line of Credit On December 19, 2017, the Company entered into a $10 million Line of Credit arrangement with Richard E. Uihlein, a director and shareholder who had an approximate 7% ownership interest in the Company on a fully-diluted basis at December 31, 2017. Originally, borrowings may be made by the Company through December 31, 2018. Borrowings bear interest at the Applicable Federal Rate for short term loans published by the Internal Revenue Service (2.7% in January 2019). All borrowings and interest were originally due on December 31, 2019 but could be prepaid without penalty. In connection with the Line of Credit agreement, the Company issued to Mr. Uihlein warrants to purchase 1 million shares of the Company’s common stock for $5 per share. Half of the warrants vested at closing of the Line of Credit and the other half vest ratably with borrowings under the agreement. There have been no borrowings under the Line of Credit to date. On December 20, 2018, the Line of Credit arrangement was extended for one year for both borrowings and maturity. At the time of the conversion of the Series B Convertible Preferred stock into common stock (See Note 9), on January 11, 2019, the Line of Credit arrangement was extended for an additional two years for both borrowings and maturity. After the second amendment to the Line of Credit arrangement, borrowings may be made through December 31, 2021 with repayment due on December 31, 2022. There was no additional consideration or benefits provided to Mr. Uihlein for any of the extensions of the Line of Credit. The fair value of the 500,000 warrants vested at closing in December 2017 was $696,000 at the date of issuance based on the following assumptions: an expected life of 7 years, volatility of 98%, risk free interest rate of 2.05% and zero dividends. The fair value of the vested warrants was recorded in other current assets and other assets (non-current) The fair value of warrants that vest in the future based on borrowings will be computed when those borrowings occur and amortized over the remaining period through December 31, 2022 reflecting the second extension. |

Fair values determined by Level 3 inputs utilize unobservable data points in which there is little or no market data, which require the reporting entity to develop its own assumptions. The carrying amounts reflected in the consolidated balance sheets for cash equivalents, accounts payable and accrued expenses approximate their carrying value due to their short-term nature. There were no level 2 or level 3 assets or liabilities at September 30, 2019 or December 31, 2018. |
