About GT-02287

Gain Therapeutics’ lead drug candidate, GT-02287, is in clinical development for the treatment of GBA1 Parkinson’s disease (GBA1-PD). The orally administered, brain-penetrant small molecule is an allosteric protein modulator that restores the function of the lysosomal protein enzyme glucocerebrosidase (GCase) which becomes misfolded and impaired due to a GBA1 gene mutation, the most common genetic abnormality associated with PD. In preclinical models of PD, GT-02287 restored GCase enzymatic function, reduced aggregated α-synuclein, neuroinflammation and neuronal death, increased dopamine levels and improved motor function. Additionally, GT-02287 significantly reduced plasma neurofilament light chain (NfL) levels, an emerging biomarker for neurodegeneration.

Gain’s lead program in Parkinson’s disease has been awarded funding support 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 GBA1 Parkinson’s Disease

GBA1 Parkinson’s disease is caused by mutations in the GBA1 gene, found in up to 15% of patients with Parkinson’s disease and making it the primary genetic risk factor. The mutation causes dysfunctional misfolding of the lysosomal enzyme glucocerebrosidase (GCase), reducing its activity in the brain and leading to the subsequent accumulation of α-synuclein and degeneration of dopamine-containing nerve cells. Patients with GBA1-PD tend to have earlier onset and faster symptom progression than those with sporadic PD, a progressive neurodegenerative disease characterized by a motor syndrome consisting of bradykinesia (slowness of movement), rigidity, resting tremors, and postural instability. With current therapies treating only the symptoms of Parkinson’s disease without affecting the underlying progression of the disease, there is an unmet need to develop novel disease-modifying therapies such as GT-02287 that have the potential to slow or stop disease progression and help improve outcomes in this patient population.
