Gain Therapeutics Inc in the News
Gain Therapeutics, Inc. (GANX) announced today topline data from its study conducted at the University of Maryland School of Medicine (UMSOM). The study, evaluating two lead Structurally Targeted Allosteric Regulators (STARs) compounds – GT-02287 and GT-02329 – for the treatment of Gaucher and GBA1 Parkinson’s Disease, demonstrated positive effects on all tested phenotypes.
From Gain Therapeutics Inc and Others
Ricardo Feldman, Ph.D., Associate Professor of Microbiology and Immunology at the University of Maryland School of Medicine, stated, “Our laboratory is using human induced pluripotent stem cells (iPSC) derived from patients with GD and GBA-associated Parkinson’s disease to test the efficacy of the two lead STAR chaperones developed by Gain Therapeutics. Our studies in iPSC-derived cortical and dopaminergic neurons from neuronopathic Gaucher Disease patients show that these compounds increase the levels of GCase protein, its transport to the lysosome, and its enzymatic activity. In dopaminergic neurons, the two lead STAR chaperones also decrease the levels of α-synuclein-p129, demonstrating their potential to treat GBA1-associated Parkinson’s Disease.”
Eric Richman, Chief Executive Officer of Gain Therapeutics Inc, stated, “These data are extremely exciting, as it further demonstrates the potential of GT-02287 and GT-02329 and expands the body of evidence supporting our Site-Directed Enzyme Enhancement Therapy (SEE-Tx™) drug discovery platform. “We plan to fully evaluate the results of this study and present a complete data set on the upcoming Michael J. Fox Foundation’s Innovating from Drug Discovery to the Clinic: Novel Approaches to PD Therapeutic Development webinar. In addition, we anticipate initiating IND-enabling studies for Gaucher / Parkinson’s Disease in the fourth quarter of this year.”
Gain Therapeutics Inc Proprietary SEE-Tx™ platform
Gain identified the two lead STAR candidates (GT-02287 and GT-02329) through its proprietary SEE-Tx™ platform. The compounds were characterized in assays to potentially help Parkinson’s patients with GBA1 gene mutations as well as patients whose glucocerebrosidase (GCase) protein is misfolded due to ageing cellular processes. This previous work was supported through grants from the Michael J. Fox Foundation (MJFF) and the Silverstein Foundation for Parkinson’s with GBA.
Mutations in GBA1 – the gene encoding the lysosomal enzyme GCase: These mutations are among the most commonly known genetic risk factors for the development of Parkinson’s Disease and related synucleinopathies. GBA1 mutations are causative for the rare autosomal storage disorder Gaucher Disease and may lead to degradation of the protein, disruptions in lysosomal targeting and diminished performance of the enzyme in the lysosome. Patients with Gaucher Disease including heterozygous carriers are at increased risk of developing Parkinson’s Disease and Dementia with Lewy Bodies.
The study conducted in collaboration with Ricardo A. Feldman, Ph.D.,Associate Professor of Microbiology and Immunology at UMSOM and lead investigator, is using human induced pluripotent stem cells (iPSC) for Gaucher and Parkinson’s Disease modeling and drug discovery. Gain’s candidate molecules GT-02287 and GT-02329 have been initially assessed in this unique “disease-in-a-dish” iPSC model derived from Gaucher type 2 and 3 patient cells.
Topline data from collaboration with University of Maryland School of Medicine on GBA-associated Parkinson’s Disease in iPSC model. The two STAR compounds achieved the following results:
- Displayed positive effects on key biological read-outs such as GCase activity, GCase protein levels, GCase transport to the lysosomes, glucosylceramide and depletion of P-alpha-synuclein: all parameters that are related to disease onset and progression.
- Increased GCase enzyme activity.
- Increased GCase protein levels and transport to the lysosome in cortical neurons
- Decreased GluCer accumulation in cortical neurons
- Increased GCase protein levels and transport to the lysosome in dopaminergic neurons
- Decreased α-synuclein-p129 levels in dopaminergic neurons
More from Gain Therapeutics Inc
Manolo Bellotto, Ph.D., General Manager at Gain Therapeutics, stated, “We appreciate the close collaboration with Dr. Feldman and the University of Maryland School of Medicine in this important area of research. The topline data demonstrates that our STARs compounds open a new potential approach for direct treatment of GBA1 Parkinson’s Disease by guiding misfolded forms of the GCase enzyme to their proper shape and restoring enzymatic activity. This is an exciting validation of our platform technology and a promising potential therapeutic opportunity for patients suffering from these debilitating diseases.”
The combined data from Gain Therapeutics and Dr. Feldman’s laboratory suggest that STARs bind to novel allosteric binding sites identified using Gain’s proprietary SEE-Tx™ drug discovery platform, stabilize, and restore enzymatic activity to misfolded GCase. In these studies, the restoration of GCase activity resulted in the depletion of the toxic phosphorylated and aggregated forms of α-synuclein and a reversal of the neurodegenerative process resulting in improved locomotor activity in Parkinson’s Disease model in rats.
Given that STARs are small molecule therapies, they have significant advantages over the current standard of care for disorders associated with protein misfolding, including most enzyme replacement therapies and gene therapies. They can be administered as a simple oral pill and can reach organs and tissues not typically accessible through current therapeutic options, including the brain, bone and cartilage. As well, the Company believes that STARs are relatively easy and cost-effective to manufacture.
“These encouraging results show promise for this approach to correct dysfunction in the GBA1 pathway, a leading target for Parkinson’s drug development,” said Marco Baptista, PhD, MJFF Vice President of Research Programs. “We look forward to hearing more on next steps to advance these potential therapies further in testing and closer to patients whose greatest unmet need is a treatment to slow or stop disease progression.”

We were waiting to hear some preliminary results and found them in today’s Gain Therapeutics press release. We liked what we read as we are interested in finding companies that can treat, or cure, diseases based on existing information as a result of the unparalleled biological revolution.
GANX is currently trading at $8.81.
A Note from Prohost Biotech
We know that most of our readers are waiting for our Prohost Biotech Comprehensive Letter issues. Writing them has taken more time then we expected but we continue our due diligence.
The reason for the delay has been a combination of the market instability and the state of the economy following the emergence of the Delta variant which has proven more contagious than the initial COVID-19 outbreak.
Our plan is still in pinpointing companies that treat devastating diseases that have never been treated.
Bottom line, we will start with what we believe will help to avoid the hospitalization of COVID-19 patients, follow up with pinpointing the firms we treasure in the Prohost Portfolio and continue with other firms we believe will bring breakthrough products.
Thank you for your patience.
