Early Parkinson's study links spinal fluid change to brain enzyme shift
Gain Therapeutics (Nasdaq: GANX) announced positive Phase 1b clinical trial results for GT-02287, a GCase modulator for Parkinson’s disease. The study demonstrated the first-ever reduction of glucosylsphingosine (GluSph) in cerebrospinal fluid (CSF) after 90 days of dosing, indicating central nervous system target engagement and increased GCase activity. The company plans a virtual KOL webinar on January 6, 2026, to discuss the results further.
