Brief summary

This is a first-in-human Phase 1 study evaluating the safety and tolerability of C.001 in patients with retinal diseases involving degeneration of the retinal pigment epithelium. Participants will receive a single administration of C.001 delivered by subretinal injection. The study will evaluate three dose levels in a sequential manner. The primary objective is to assess the safety of C.001 over a 3-month period following administration. Participants will be followed for up to 12 months to further evaluate safety and explore changes in visual function and retinal structure.

Detailed description

This is a Phase 1, single-center, open-label, dose-escalation study designed to evaluate the safety and tolerability of C.001 administered via subretinal injection. Participants will be enrolled into three sequential dose cohorts. A sentinel dosing strategy will be used, with safety review by an independent Data Safety Monitoring Board (DSMB) prior to escalation to higher dose levels. A minimum observation period of 4 weeks will be required between dose escalations. Participants will be followed for up to 12 months after treatment for safety assessments and exploratory evaluation of visual and anatomical outcomes.
