Summary

This study tests an oral medication called STL303 in 300 adults aged 60 and older who have geographic atrophy, a form of advanced dry age-related macular degeneration that causes a blind spot in central vision. The goal is to see if the drug can slow the death of light-sensing cells in the eye and preserve sight. Participants will be randomly assigned to receive either STL303 or a placebo pill for a set period, and researchers will monitor safety and changes in vision.
