简要总结
This is a clinical study to evaluate the safety, tolerability and efficacy of CTx001, administered via a single subretinal injection, for GA (secondary to AMD).
Safety and efficacy will be measured at regular intervals for 2 years after which long-term safety will be assessed annually for up to 5 years.
