BETHESDA, MD, Mar 14, 2025 – (ACN 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.
