A Phase 1/2 interventional study of EXG202 injection in Wet Age-related Macular Degeneration, sponsored by Guangzhou Jiayin Biotech Ltd. Not yet recruiting. Open to participants aged 50 Years and older. Per ClinicalTrials.gov, last updated 2025-09-17.
Sponsored by Guangzhou Jiayin Biotech Ltd · Phase 1/2, Interventional, and Treatment
VEGF inhibitors (anti-VEGF),such as aflibercept has been shown to be safe and effective for treating nAMD and have demonstrated improvement in vision. However, anti-VEGF therapy is administered frequently via intravitreal injection and can be a significant burden to the patients.
EXG 202 is a recombinant adeno-associated virus (rAAV) gene therapy vector carrying a coding sequence for a soluble anti-VEGF protein. The long-term, stable delivery of this therapeutic protein following a 1 time gene therapy treatment for nAMD could potentially reduce the treatment burden of currently available therapies while maintaining vision with a favorable benefit.
This Phase I/II study was designed to evaluate the safety and Preliminary Efficacy of EXG202 gene therapy in subjects with nAMD. Subjects who met the inclusion/exclusion criteria and had response to an initial anti-VEGF injection received a single dose of EXG202 administered . Safety was the primary focus for the phase I/II trial ,at the same time ,preliminary Efficacy also is another goal for the trial.
