GT-02287 in Parkinson's Disease: Interim Data from a Phase 1b Study
(MDS Congress 2025)
- "GT-02287 is a GCase-targeting small molecule that successfully completed Phase 1 in healthy volunteers and that is currently being evaluated in people with PD. Based on the genetic association of GBA1 variants with PD and extensive preclinical data demonstrating that GT-02287 modulates molecular pathways implicated in PD, this novel compound has the potential to slow disease progression in GBA1-PD and possibly in idiopathic PD."

Gain Therapeutics Presents Initial Data from Phase 1b Clinical Study of GT-02287 in Parkinson’s Patients at International Congress of Parkinson’s Disease and Movement Disorders
(GlobeNewswire)
- "Mean MDS-UPDRS scores at baseline were 5.8, 7.4, and 24.7 for Parts I, II, and III, respectively. Importantly, several participants experienced an improvement in their UPDRS Part II and III scores after 90 days of dosing with GT-02287 while mean Part I scores remained unchanged. The mean improvement in Parts II and III by Day 90, which was not observed by Day 30, suggests that GT-02287 has a disease-slowing effect..."

Gain Therapeutics Presents Preclinical Data at IAPRD 2025 30th World Congress on Parkinson's Disease and Related Disorders
(GlobeNewswire)
- "In cultured rat mesencephalic dopaminergic neurons treated with MPP+, a mitochondrial toxin that induces mitochondrial impairment by inhibiting mitochondrial complex 1, GT-02287 improved the function of both the lysosomes and mitochondria and exerted a broader neuroprotective effect. GT-02287 lowered α-synuclein aggregation, lysosomal dysfunction, and mitochondrial stress while also preventing the release of mitochondrial cytochrome C, a programmed cell death (apoptosis) signal, thereby promoting neuronal survival."

Allosteric Modulation of GCase Enhances Lysosomal Activity and Reduces ER Stress in GCase-Related Disorders.
(PubMed, Int J Mol Sci)
- "Using Site-directed Enzyme Enhancement Therapy (SEE-Tx®), two structurally targeted allosteric regulators (STARs), GT-02287 and GT-02329, were developed and tested in GD patient-derived fibroblasts with relevant GCase variants. This enhanced lysosomal function and reduced cellular stress. These findings validate the STARs' mechanism of action and highlight their therapeutic potential for GCase-related disorders, including GD, PD, and Dementia with Lewy Bodies."
