Gain Therapeutics Receives Approval to Commence Phase 1 Clinical Study of GT-02287 from the Human Research Ethics Committee (HREC) in Australia

                First drug candidate identified with Gain’s proprietary computational drug discovery platform SEE-Tx^® to enter clinical development phase

BETHESDA, Md., Sept. 12, 2023 (GLOBE NEWSWIRE) -- Gain Therapeutics, Inc. (Nasdaq: GANX) (“Gain”, or the “Company”), a biotechnology company leading the discovery and development of the next generation of allosteric small molecule therapies, today announced that the Company has received approval from the Bellberry Human Research Ethics Committee (HREC) in Australia to initiate a Phase 1 clinical study of its lead drug candidate GT-02287 in development for GBA1-Parkinson’s disease (GBA1-PD). Dosing in healthy volunteers to assess the safety and pharmacokinetics of GT-02287 is expected to begin in the near term.

“Following the recent presentation of encouraging preclinical data at the International Congress of Parkinson's Disease and Movement Disorders^® showing the robust effect of GT-02287 against PD-associated pathology and its ability to significantly decrease plasma NfL levels, an emerging biomarker for neurodegeneration, we are pleased to receive HREC’s approval to enable the advancement of GT-02287 into the clinic,” said Matthias Alder, Chief Executive Officer of Gain Therapeutics. “This approval is a key step for Gain and further validates our differentiated allosteric approach and our computational drug discovery platform as we endeavor to bring a novel, potentially disease-modifying therapeutic to patients with GBA1-Parkinson’s disease.”

About GT-02287

Gain Therapeutics’ lead drug candidate, GT-02287, is in development for the treatment of GBA1 Parkinson’s disease (GBA1-PD). The orally available, 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.

The program 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. A Phase 1 trial of GT-02287 is scheduled to begin in the near term.

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 subsequent neurodegeneration of dopamine cells. Patients with GBA1-PD tend to have earlier onset and faster symptom progression than 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.

About Gain Therapeutics, Inc.

Gain Therapeutics, Inc. is a biotechnology company leading the discovery and development of next generation allosteric therapies. Gain’s lead drug candidate GT-02287, in development for the treatment of GBA1 Parkinson’s disease, has been approved for clinical testing in Australia.

Leveraging AI-supported structural biology, proprietary algorithms and supercomputer-powered physics-based models, the company’s SEE-Tx^® discovery platform can identify novel allosteric binding sites on disease-implicated proteins, pinpointing pockets that cannot be found or drugged with current technologies. Gain’s unique approach enables the discovery of novel, allosteric small molecule modulators that can restore or disrupt protein function. Deploying its highly advanced platform, Gain is accelerating drug discovery and unlocking novel disease-modifying treatments for untreatable or difficult-to-treat disorders including neurodegenerative diseases, rare genetic disorders and oncology.
