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. 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 allows 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.
