The event will also review biomarker results from the Phase 1b clinical study of GT-02287, demonstrating disease modifying potential in Parkinson’s disease patients with or without a GBA1 mutation.

A live question and answer session will follow the formal presentations.

About Roy Alcalay, M.D., M.Sc.

Roy Alcalay, M.D., M.Sc. is chief of the Movement Disorders Division at Tel Aviv Sourasky Medical Center and the Norma and Alan Aufzien Professor of Neurology at the Gray Faculty of Medical & Health Sciences, Tel Aviv University, Israel. He moved from Columbia University where he continues to hold a part-time position focusing on research and education. He obtained his medical degree from Tel Aviv University, his neurology training from the Harvard University residency program at Massachusetts General Hospital and Brigham and Women’s Hospital, and his training in movement disorders at Columbia University. He earned a master’s degree in biostatistics (patient-oriented research track) from Columbia University. His research focuses on biomarkers and genetics in Parkinson’s disease. He is a member of the executive steering committee of The Michael J. Fox Foundation-funded PPMI study and the principal investigator of the Parkinson’s Foundation-funded study PD GENEration. He serves on the scientific advisory boards of the Parkinson’s Foundation and the Silverstein Foundation for Parkinson’s with GBA.

About Peter Lansbury, Ph.D.

Peter Lansbury, Ph.D. is a Professor of Neurology at Harvard University. For the past thirty years, he has studied the biochemical processes underlying Alzheimer's disease, Parkinson's disease, prion disease, and ALS, with the goal of translating this knowledge into novel medicines. Peter and his research group have authored numerous papers in the area of protein aggregation as it relates to neurodegeneration. His laboratory was the first to over express alpha-synuclein and to characterize its structural properties. He was awarded a Presidential Young investigator Award by the National Science Foundation and a Zenith Fellow award from the Alzheimer's Association. Dr. Lansbury also founded and directed several key research initiatives, including the Laboratory for Drug Discovery in Neurodegeneration and the Morris K. Udall NIH Parkinson’s Disease Research Center of Excellence at Brigham and Women’s Hospital, where he served as director for a decade. Peter was previously Founder and Chief Science Officer of Link Medicine through its sale to AstraZeneca and Chief Science Officer at Lysosomal Therapeutics, Inc. through its sale to Bial.

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 ER stress, lysosomal and mitochondrial pathology, aggregated α-synuclein, neuroinflammation and neuronal death, as well as plasma neurofilament light chain (NfL) levels, a biomarker of neurodegeneration. In rodent models of both GBA1-PD and idiopathic PD, GT-02287 was shown to rescue deficits in motor function and gait and prevent the development of deficits in complex behaviors such as nesting.

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.

Results from a Phase 1 study of GT-02287 in healthy volunteers demonstrated favorable safety and tolerability, plasma and CNS exposures in the projected therapeutic range, and target engagement with an increase in glucocerebrosidase (GCase) activity among those receiving GT-02287 at clinically relevant doses.

GT-02287 is currently being evaluated in a Phase 1b clinical trial for the treatment of Parkinson’s disease with or without a GBA1 mutation. The primary endpoint of the trial, which enrolled participants across seven sites in Australia, is to evaluate the safety and tolerability of GT-02287 after three months of dosing in people with Parkinson’s disease. The recently commenced Phase 1b study extension allows participants to continue to be treated with GT-02287 for up to a total of 12 months.

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.
