Summary

This early-stage study tests a new treatment called C.001 for people with retinal diseases that cause vision loss, such as geographic atrophy and Stargardt disease. The treatment is given as a single injection into the eye. The main goal is to check if it is safe, and researchers will also look for any changes in vision or eye structure over 12 months.
