Phase 1 Study of C.001 in Retinal Degeneration

A Phase I Single-Center Open-label Study of C.001 in Patients With Significant Retinal Pigment Epithelium Mediated Maculopathy (RMM)

Source: ClinicalTrials.gov · Last updated 3 Nov 2026

Brief summary (registry, in English)

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.
