Accumulating Preclinical Data Provide Further Support for Disease-Modifying Potential of Brain Penetrant Investigational Small Molecule Therapeutic, GT-02287
Results Presented at the Shaare Zedek Medical Center GBA-Parkinson’s Disease Symposium
BETHESDA, Md., Sept. 26, 2022 (GLOBE NEWSWIRE) -- Gain Therapeutics, Inc. (Nasdaq: GANX) (“Gain”, or the “Company”), a biotechnology company transforming drug discovery with its proprietary computational drug discovery platform identifying novel allosteric binding sites and creating small molecule treatments, today announced the presentation of new preclinical data evaluating one of its lead Structurally Targeted Allosteric Regulator (STAR) compounds, GT-02287, for the treatment of Parkinson’s Disease.
Study results were presented at the Shaare Zedek Medical Center GBA Parkinson’s disease symposium by Manolo Bellotto, Ph.D., Chief Strategy Officer & General Manager for Gain Therapeutics, in a presentation entitled, “Non-inhibitory Chaperones for GBA-Parkinson’s Disease.”
The study was conducted using human induced pluripotent stem cells (iPSC) derived from donor patients with GBA-associated Parkinson’s disease, which were then differentiated into dopaminergic neurons. This “Disease in a dish” model is a cutting-edge research strategy used to model diseases outside the human body. In this study, GT-02287, the Company’s lead compound in its Parkinson’s program, demonstrated statistically significant, positive effects across a range of measurable parameters, including an increase in GCase levels and lysosomal transport measured by GCase co-localization into the lysosomes. It also reduced pathologically elevated levels of phosphorylated and aggregated α-synuclein, which are known to be a critical marker of Parkinson’s-induced neurodegeneration.
“We are especially excited by these latest data because they were generated in a model that replicates Parkinson’s disease in patient-derived cells,” commented Matthias Alder, Chief Executive Officer of Gain Therapeutics. “The consistency and strength of these latest data not only support our earlier findings in iPSC-derived neuronal cells from neuronopathic Gaucher Disease patients, but, more importantly, offer further compelling evidence of the disease-modifying potential and unique mechanism of action of our approach.”
The accumulating preclinical data for GT-02287 demonstrate that Gain’s orally bioavailable, brain penetrant small molecule candidate stabilizes and restores the function of misfolded GCase, thus correcting a prominent enzymatic dysfunction underlying GBA1 Parkinson’s disease pathology. Approximately 14% of Parkinson’s disease patients are known to possess a mutation in the GBA1 gene, which encodes for the lysosomal enzyme GCase, and represents the most common genetic risk factor for Parkinson’s disease. GBA1 genetic mutations are associated with earlier onset disease and more aggressive disease progression. Gain believes that GT-02287, with its ability to restore GCase enzyme function, may be able to protect against, or possibly reverse, the damaging cascade of neuronal degeneration implicated in serious CNS disorders like Parkinson’s disease.
About Parkinson’s Disease
Mutations in the GBA1 gene, encoding the lysosomal enzyme GCase, represents the most common genetic risk factor for Parkinson’s disease (PD). Impaired GCase function has garnered attention due to its association with α-synuclein pathology in GBA-associated PD patients, but also in sporadic PD, as well as in related α-synucleopathies. Although less investigated, decreased GCase levels and activity are also implicated in the pathophysiology of Alzheimer’s disease (AD). Enhancing the activity of mutant and wild-type GCase may represent a therapeutic strategy for the treatment of a range of neurodegenerative diseases.
About Gain Therapeutics, Inc.
Gain Therapeutics, Inc. is transforming the drug discovery paradigm with structurally targeted allosteric regulators identified with its proprietary computational discovery platform SEE-Tx®. The ability to identify never-seen-before allosteric targets on proteins involved in diseases across the full spectrum of therapeutic areas provides opportunities for a range of drug-protein interactions, including protein stabilization, protein destabilization, targeted protein degradation, allosteric inhibition and allosteric activation. Gain’s pipeline spans neurodegenerative diseases, lysosomal storage disorders, metabolic diseases and oncology. 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.
