This is a single-arm, open-label, and multi-center study of ZVS101e in patients with BCD. Up to 24 subjects are expected to be enrolled. Each participant will receive ZVS101e by subretinal injection in one eye on a single occasion. Safety, efficacy and vector shedding characteristics of ZVS101e are then measured over 180 days. Participants will subsequently enter a long-term follow-up study over a 4.5-year period.
The purpose of this study was to evaluate the safety and efficacy of ZVS101e administered by subretinal injection in subjects with Bietti's crystalline dystrophy (BCD) and to select the optimal effective dose.
