Summary
- Primary objective: To assess the safety and tolerability of the AAV.REP1 vector, administered at two different doses to the retina in 12 patients with a diagnosis of choroideremia. - Secondary Objective: To identify any therapeutic benefit as evidenced by a slowing down of the retinal degeneration assessed by functional and anatomical methods in the treated eye compared to the control eye 24 months after gene delivery.
