Summary
The study is a Phase 3, open-label, randomized controlled trial of gene therapy intervention by subretinal administration of AAV2-hRPE65v2 (voretigene neparvovec-rzyl). At least twenty-four subjects, three years of age or older, will be recruited. The intervention group will receive AAV2-hRPE65v2 at either The Children's Hospital of Philadelphia or University of Iowa to determine if it improves visual and retinal function in individuals with RPE65 gene mutations.
