Gain Therapeutics (NASDAQ: GANX) cuts Q2 net loss while pushing Parkinson’s drug forward
Rhea-AI Filing Summary
Gain Therapeutics reported second quarter 2026 results and provided an update on its Parkinson’s disease program. The company highlighted FDA authorization of its IND for rexaceract, supporting advancement into planned Phase 2 development, and ongoing enrollment and follow-up in a Phase 1b trial, including a nine‑month extension with data expected in October 2026.
For the quarter ended June 30, 2026, research and development expenses were $2.1 million, down from $2.8 million a year earlier, mainly due to lower costs for rexaceract and pipeline optimization, partially offset by the expiration of Swiss grant funding and foreign exchange effects. General and administrative expenses were $2.5 million, up from $2.3 million, driven by higher professional fees, personnel costs and currency impacts. Net loss was $4.7 million, or $0.11 per share, compared with $5.8 million, or $0.19 per share, in the prior‑year quarter.
As of June 30, 2026, cash and cash equivalents were $13.1 million, down from $20.8 million as of December 31, 2025. Total assets were $15.4 million and stockholders’ equity was $11.3 million. Gain continues to position rexaceract, a brain‑penetrant allosteric modulator of beta‑glucocerebrosidase, as a potential disease‑modifying therapy for Parkinson’s disease and other indications.

Exhibit 99.1
Gain Therapeutics Reports Financial Results for Second Quarter 2026 and Provides Corporate Update
BETHESDA, Md., August 11, 2026 -- 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 June 30, 2026, and provided a corporate update.
“The second quarter marked an important period of execution for Gain, highlighted by FDA authorization of our IND for rexaceract, which positions us to advance into Phase 2 clinical development,” said Gene Mack, President and CEO of Gain Therapeutics. “The encouraging biomarker and clinical data generated to date continue to support the potential disease-modifying properties of rexaceract, and we were pleased to further share these findings with the scientific community at the 3rd International GBA1 Meeting. We believe these data further strengthen the therapeutic rationale for rexaceract across both idiopathic and GBA1 Parkinson’s disease.”
Mr. Mack continued, “We remain focused on completing the ongoing nine-month extension of our Phase 1b study, with final data expected to be presented at the International Congress of Parkinson’s Disease and Movement Disorders in Korea in October 2026, while advancing preparations for our Phase 2 clinical program. As of June 30, 2026, 14 of the 16 participants that elected to enroll in the Phase 1b nine-month extension had completed Day 270 with seven of those crossing the Day 360 mark. To date, MDS-UPDRS scores continue to demonstrate that patients with high baseline CSF GluSph experience an early and durable response to rexaceract that persists through Day 270 and Day 360, while the overall patient group continues to benefit from non-progression of their Parkinson’s symptoms through Day 360. We continue to believe rexaceract has the potential to shift the treatment paradigm beyond symptom management by addressing the underlying biology of Parkinson’s disease, and we look forward to achieving additional clinical and regulatory milestones throughout the remainder of the year.”

Q2 2026 Financial Results
Research and development (R&D) expenses decreased by $0.6 million to $2.1 million for the three months ended June 30, 2026, compared to $2.8 million for the three months ended June 30, 2025. The decrease in research and development expenses was primarily related to lower costs associated with our lead program compound GT-02287 (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 and unfavorable foreign exchange currency translation as the Swiss franc and Australian dollar strengthened against the U.S. dollar.
General and administrative (G&A) expenses increased by $0.2 million to $2.5 million for the three months ended June 30, 2026, compared to $2.3 million for the three months ended June 30, 2025. The increase in general and administrative expenses for the period was primarily attributable to higher professional fees, higher personnel costs, and unfavorable foreign exchange currency translation as the Swiss franc strengthened against the U.S. dollar.
Net loss for the three months ended June 30, 2026, was $0.11 per share, basic and diluted, compared to $0.19 per share, basic and diluted, for the three months ended June 30, 2025.
Cash and cash equivalents were $13.1 million as of June 30, 2026, compared to $20.8 million as of December 31, 2025.
About Rexaceract
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, rexaceract 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 rexaceract, suggest that rexaceract may have the potential to slow or stop the progression of Parkinson’s 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 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 rexaceract after three months of dosing in people with Parkinson’s disease. The Phase 1b study extension allows participants to continue to be treated with rexaceract 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.
