Item 7.01. Reguation FD Disclosure.
On March 18, 2026, Gain Therapeutics, Inc. (the “Company”) issued a press release regarding the information described below in Item 8.01, which press release is attached hereto as Exhibit 99.1 and is incorporated by reference herein.
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, as amended, or the Exchange Act, except as shall be expressly set forth by a specific reference in such filing.
Item 8.01. Other Events.
On March 18, 2026, the Company issued a press release announcing the presentation of an oral presentation and poster at AD/PD ™ 2026 International Conference on Alzheimer’s and Parkinson’s Disease and Related Neurological Disorders, being held March 17-21, 2026 in Copenhagen, Denmark. The oral presentation outlined new clinical and biomarker data from the Phase 1b clinical study of GT-02287 further supporting disease-modifying potential in both idiopathic and GBA1 Parkinson’s disease. The Company also presented a poster outlining preclinical data from a structurally distinct chemical series of allosteric glucocerebrosidase (GCase) modulators, which are ready for IND-enabling studies for the treatment of Parkinson’s disease (PD) and other neurological disorders.
AD/PD Oral Presentation
The oral presentation, entitled, “An Open-Label Phase 1b Study of GT-02287 in Parkinson’s Disease,” was delivered on-site by the Company’s Chief Medical Officer, Jonas Hannestad, M.D., Ph.D. Data on safety, tolerability, biomarkers, and clinical scores from the completed Part 1 of the study was presented. Of the 19 participants who completed dosing in Part 1, 16 chose to continue in the ongoing nine-month extension (Part 2). A Data Monitoring Committee meeting on March 5, 2026, concluded that the study should continue without any changes.
As previously presented in January 2026, in all participants with elevated baseline levels of glucosylsphingosine (GluSph) in cerebrospinal fluid (CSF), GluSph decreased substantially after 90 days of treatment with GT-02287.
As of March 10, 2026, of the 16 participants enrolled in the ongoing nine-month extension, 14 had completed dosing for five months (Day 150). MDS-UPDRS scores remained stable over 150 days of dosing. Preliminary data (subject to quality assurance) suggests that participants with elevated baseline levels of GluSph in CSF continued to benefit more than those with low baseline levels of GluSph in CSF, with a difference of 6.7 points in the sum of MDS-UPDRS Part II and Part III scores between the two groups at Day 150. Additionally, in individuals with high levels of CSF GluSph at baseline, levels of DOPA decarboxylase (DDC) decreased following 90 days of treatment with GT-02287.
AD/PD Poster Presentation
The poster, titled, “Novel Allosteric GCase Modulators, Different From the Clinical Stage GT-02287, for the Treatment of Parkinson’s Disease,” was presented on-site by the Company’s Head of Research Ana Maria Garcia-Collazo, Ph.D. The new, orally available, brain penetrant chemical series – led by GT-04686 – demonstrates potential for future clinical development, as evidenced by restoration of key biological activities that are impaired in Parkinson’s disease.
