Gain Therapeutics Doses First Participant in Phase 1b Clinical Trial of GT-02287 in Parkinson’s Disease

Interim Analysis Expected End of 2Q 2025

BETHESDA, Md., March 14, 2025 (GLOBE NEWSWIRE) -- Gain Therapeutics, Inc. (Nasdaq: GANX) (“Gain”, or the “Company”), a clinical-stage biotechnology company leading the discovery and development of the next generation of allosteric small molecule therapies, today announced the dosing of the first participant with Parkinson’s disease (PD) in its Phase 1b clinical trial of GT-02287, the Company’s lead allosteric small molecule in development for the treatment of PD with or without a GBA1 mutation.

“Initiation of dosing in our Phase 1b clinical trial represents an important step in the clinical development of GT-02287 and in Gain’s mission to deliver a disease-modifying therapy to people with Parkinson’s disease. We look forward to continued enrollment and anticipate an interim analysis from the towards the end of 2Q 2025,” said Gene Mack, President and CEO of Gain Therapeutics.

The Phase 1b open-label, multi-center trial is designed to evaluate the safety and tolerability of GT-02287 in people with GBA1-PD and idiopathic PD. Secondary endpoints include pharmacokinetics, GCase modulation, levels of GCase substrates, and other biomarkers in plasma and cerebrospinal fluid. The trial will enroll up to 20 participants who will receive GT-02287 daily for three months. Interim data from the Phase 1b trial are anticipated at the end of 2Q 2025.

The Phase 1b trial follows Gain’s successful Phase 1 study in healthy volunteers completed during Q3 2024, in which GT-02287 demonstrated a favorable safety and tolerability profile as well as plasma and CNS exposures in the projected therapeutic range. Importantly, the Phase 1 study also showed significant target engagement of GT-02287 demonstrated by a statistically significant increase in glucocerebrosidase (GCase) activity that was >50%.

About GT-02287

Gain Therapeutics’ lead drug candidate, GT-02287, is in clinical development for the treatment of Parkinson’s disease (PD) with or without a GBA1 mutation. The orally administered, brain-penetrant small molecule is an allosteric enzyme modulator that restores the function of the lysosomal enzyme glucocerebrosidase (GCase) which becomes misfolded and impaired due to mutations in the GBA1 gene, the most common genetic abnormality associated with PD, or other age-related stress factors. In preclinical models of PD, GT-02287 restored GCase enzymatic function, reduced aggregated α-synuclein, neuroinflammation and neuronal death, and improved motor function and cognitive performance. Additionally, GT-02287 significantly reduced plasma neurofilament light chain (NfL) levels, an emerging biomarker of neurodegeneration.

Compelling preclinical data in models of both GBA1-PD and idiopathic PD, demonstrating a disease-modifying effect after administration of GT-02287, suggest that GT-02287 may have the potential to slow or stop the progression of Parkinson’s disease.

Gain’s lead program in Parkinson’s disease has been awarded funding support early in its development from The Michael J. Fox Foundation for Parkinson’s Research (MJFF) and The Silverstein Foundation for Parkinson’s with GBA, as well as from the Eurostars-2 joint program with co-funding from the European Union Horizon 2020 research and Innosuisse – Swiss Innovation Agency.

About Gain Therapeutics, Inc.

Gain Therapeutics, Inc. is a clinical-stage biotechnology company leading the discovery and development of next generation allosteric therapies. Gain’s lead drug candidate, GT-02287 is currently being evaluated for the treatment of Parkinson’s disease with or without a GBA1 mutation. Results from a Phase 1 study of GT-02287 in healthy volunteers demonstrated favorable safety and tolerability, plasma exposure in the projected therapeutic range, CNS exposure, and target engagement and modulation of GCase enzyme.

Gain’s unique approach enables the discovery of novel, allosteric small molecule modulators that can restore or disrupt protein function. Deploying its highly advanced Magellan™ platform, Gain is accelerating drug discovery and unlocking novel disease-modifying treatments for untreatable or difficult-to-treat disorders including neurodegenerative diseases, rare genetic disorders and oncology.
