Gain Therapeutics Reports Financial Results for Third Quarter 2026 and Provides Corporate Update
BETHESDA, Md., Nov. 10, 2026 (GLOBE NEWSWIRE) -- Gain Therapeutics, Inc. (Nasdaq: GANX) (“Gain”, or the “Company”), a clinical-stage biotechnology company leading the discovery and development of the next generation of allosteric small molecule therapies, today reported financial results for the quarter ended September 30, 2026, and provided a corporate update.
“The third quarter marked an important period of progress for Gain, highlighted by the presentation of long-term open-label data from the Phase 1b trial of rexaceract in Parkinson’s disease (PD),” said Gene Mack, President and CEO of Gain Therapeutics. “After 12 months of dosing with rexaceract, participants enrolled in the study showed no progression of Parkinson’s disease motor symptoms. This, together with previously reported biomarker evidence of target engagement, further validates the disease-modifying hypothesis underpinning our development strategy for rexaceract in PD. We continue to believe rexaceracthas the potential to shift the treatment paradigm beyond symptom management, and we look forward to achieving additional potential clinical and regulatory milestones throughout the remainder of the year.”
Mr. Mack continued, “As we approach the start of the Phase 2 clinical trial of rexaceract, which we expect to initiate during Q1 2027 after confirming updates to our trial design during Q4 2026, we plan to select an initial therapeutic indication to advance GT-04686 into the clinic. We believe advancing a second allosteric small molecule candidate into clinical development is a milestone that will help position us for our next phase of growth as we build a differentiated GCase-targeting platform with the potential to unlock multiple therapeutic opportunities.”
Third Quarter 2026 and Recent Corporate and Pipeline Highlights
Pipeline Updates
Rexaceract
- Presented long-term open-label extension data from the Phase 1b clinical study of rexaceract that supported its disease-modifying potential through 12 months of administration at the International Congress of Parkinson’s Disease and Movement Disorders in October 2026 in Seoul, Korea.
- As of August 31, 2026, MDS-UPDRS motor scores demonstrated stability when compared to baseline (as recorded at study entry) with no disease progression as measured by the MDS-UPDRS Parts II and III scales among the 12 evaluable participants who had completed 12 months of daily oral administration of rexaceractby this date.
- Participants with both high and low baseline levels of the glucocerebrosidase (GCase) substrate glucosylsphingosine (GluSph) in cerebrospinal fluid (CSF) have shown stabilization of MDS-UPDRS motor scores after 12 months and no clinically meaningful progression of motor symptoms on the MDS-UPDRS Parts II and III.
- Preliminary long-term data demonstrated that rexaceract is generally well tolerated over 12 months of dosing. No new safety signals were observed and overall, a lower incidence of TEAEs occurred in Part 2 of the study (nine-month open-label extension) compared with Part 1 (initial three-month administration).
- Perceived benefits most commonly described included four instances of improved sense of smell and taste, four instances of improved balance or gait, and three instances of improved sleep.
Corporate Updates
Regulatory
- Initiation of rexaceractPhase 2 clinical trial expected during Q1 2027 following a comprehensive redesign and submission of new Phase 2 protocol.
Management Changes
- Addition of Jeanette Weidner as Vice President, Finance, supporting strategic operations for the Company’s next phase of corporate and clinical development.
Upcoming Anticipated Milestones
- Phase 2 clinical trial of rexaceractin people with Parkinson’s disease expected to begin in Q1 2027.
- GT-04686 initial target indication expected in Q4 2026.
Q3 2026 Financial Results
Research and development (R&D) expenses decreased by $1.4 million to $1.4 million for the three months ended September 30, 2026, compared to $2.8 million for the three months ended September 30, 2025. The decrease in research and development expenses was primarily related to lower costs associated with our lead program compound rexaceract for the treatment of Parkinson’s disease and optimization of the pipeline together with lower research and development personnel expenses, partially offset by the expiration of the grant awarded by Innosuisse under the Swiss Accelerator program in April 2026.
General and administrative (G&A) expenses decreased by $0.1 million to $1.8 million for the three months ended September 30, 2026, compared to $1.9 million for the three months ended September 30, 2025. The decrease in general and administrative expenses for the period was primarily attributable to lower professional fees and personnel costs.
Net loss for the three months ended September 30, 2026, was $0.07 per share, basic and diluted, compared to $0.15 per share, basic and diluted, for the three months ended September 30, 2025.
Cash and cash equivalents were $11.7 million as of September 30, 2026, compared to $20.8 million as of December 31, 2025.
AboutRexaceract
Gain Therapeutics’ lead drug candidate rexaceract, formerly known as 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 a beta-glucocerebrosidase (GCase) positive allosteric modulator, antiparkinsonian, that restores the function of the lysosomal enzyme 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, by stabilizing and chaperoning it to the lysosomes and mitochondria. In preclinical models of PD, rexaceract restored GCase enzymatic function, reduced endoplasmic reticulum 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, rexaceractwas shown to rescue deficits in motor function and gait and prevent the development of deficits in complex behaviors such as nesting. Washout experiments in both GBA1-PD and idiopathic PD models, in which behavioral and neurochemical rescue effects seen with rexaceract were maintained even once it had been removed, suggest that rexaceract may have the potential to slow or stop the progression of the disease.
Results from a Phase 1 study of rexaceract in healthy volunteers demonstrated favorable safety and tolerability, plasma and CNS exposures in the projected therapeutic range, and target engagement with an increase in GCase activity among those receiving rexaceract at clinically relevant doses.
Rexaceract is currently being evaluated in a Phase 1b clinical trial for the treatment of PD 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 rexaceract after three months of dosing in people with PD. The Phase 1b study extension allowed participants to continue to be treated with rexaceract for up to a total of 12 months.
Gain’s lead program in PD 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.
