Study of GAL-101 Eye Drops to Slow Geographic Atrophy Progression in Adults with Non-neovascular Age-related Macular Degeneration

What this Trial Is About

Age-related macular degeneration AMD is a common condition affecting many older adults, leading to a loss of light-sensitive cells in the retina called Geographic Atrophy GA. GA starts as a small spot away from the central vision area fovea and grows over time, causing severe vision loss when it reaches the fovea. This study is investigating whether GAL-101 eye drops can slow the growth of GA and help preserve vision in affected patients. Participants in this study will use eye drops containing GAL-101 or placebo daily. The treatment involves applying two drops of the assigned solution at 5-minute intervals each day. The study eye will be chosen based on vision and retinal health criteria, and only that eye will receive the eye drops. The treatment period lasts between 12 and 24 months, with visits scheduled at screening, baseline, 2 weeks by phone, and clinic visits at 1, 3, 6, 9, and 12 months, then every 3 months thereafter until the last patient completes 12 months of treatment. Participants will undergo several assessments including imaging and vision tests to track GA lesion size and photoreceptor degeneration. The study will measure how well GAL-101 slows GA growth over 48 to 96 weeks. Safety and efficacy will be monitored throughout the treatment period. The total participation time varies but includes regular clinic visits and phone contacts for up to two years or more depending on individual treatment duration.
