简要总结
The goal of this clinical trial is to evaluate the safety and efficacy of PUMCH-E101 injection in subjects with RDH12 retinopathy.
详细描述
This is an open-label, single-center, dose-escalation study. One eye of each participant will receive a single intravitreal injection of PUMCH-E101. Participants will be followed for 52 weeks after which they will continue to be followed for up to 5 years after enrollment.

- •At screening, the blood pregnancy test result of females of childbearing potential (e.g., females who have not undergone surgical sterilization or less than 1 year after menopause) is negative. Male and female subjects of childbearing potential agree to use effective contraception throughout the study and for at least 12 months after dosing.
排除标准
