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.

The goal of this clinical trial is to evaluate the safety, tolerability and efficacy of intravitreal injection of EXG202 in subjects with neovascular age-related Macular Degeneration (nAMD).

This is a long-term, safety and efficacy follow-up study of patients in the EXG102-031-111 gene therapy clinical trial for wAMD. Patients will complete visits from the parent study, and then into this long-term follow-up study for continuous safety monitoring for up to 5 years.
