Item 7.01. Regulation FD Disclosure.

On December 23, 2024, Gain Therapeutics, Inc. (the “Company”) issued a press release announcing it has received approval in Australia to initiate a Phase 1b clinical trial. A copy of the press release is furnished hereto as Exhibit 99.1.

The information in this Current Report on Form 8-K under Item 7.01, including the information contained in Exhibit 99.1, is being furnished to the SEC and shall not be deemed to be “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, and shall not be deemed to be incorporated by reference into any filing under the Securities Act of 1933 or the Exchange Act, except as shall be expressly set forth by a specific reference in such filing.

Item 8.01 Other Information

On December 23, 2024, the Company issued a press release announcing that it has received approval in Australia to initiate a Phase 1b clinical trial. The Company will be working with local Parkinson’s disease (“PD”) advocacy groups to support enrollment, and expects enrollment to complete in the spring of 2025 with data from the study expected mid-2025. GT-02287 is the Company’s lead allosteric small molecule in clinical development for the treatment of PD with or without a GBA1 mutation.

The primary goal of the Phase 1b trial is to assess the safety and tolerability of GT-02287 in people with PD. The Phase 1b trial will follow the Company’s Phase 1 study in healthy volunteers completed during the third quarter of 2024, in which GT-02287 demonstrated a favorable safety and tolerability profile as well as plasma and CNS exposures in the projected therapeutic range. The Phase 1 study also showed significant target engagement of GT-02287 demonstrated by a statistically significant increase in glucocerebrosidase (GCase) activity that was more than 50%.

The Phase 1b clinical trial of GT-02287 will be conducted at seven sites covering the major metropolitan areas in Australia, all of which have experience with PD trials.

The Phase 1b open-label trial will assess the safety and tolerability of 13.5 mg/kg/day of GT-02287 for three months in patients with GBA1-PD or idiopathic PD. Secondary endpoints include pharmacokinetics, GCase modulation, levels of GCase substrates, and other biomarkers in plasma and cerebrospinal fluid. Data from the Phase 1b trial is anticipated mid-2025.
