Geographic Atrophy of the Macula study: GAL-101
Official title A Phase 2 Efficacy and Safety Study of GAL-101, 2% Ophthalmic Solution in Non-foveal Geographic Atrophy Secondary to Non-neovascular AMD
ClinicalTrials.gov ID: NCT06659549
What this study is testing
What is GAL-101?
GAL-101 is an investigational eye drop being studied for geographic atrophy of the macula.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The study wants to see if GAL‑101 can slow the growth of geographic atrophy and keep it from reaching the central part of the retina.
- Who it's for
- Adults with geographic atrophy that has not yet reached the fovea (central vision area).
- What's involved
- Participants will use eye drops every day. Some drops contain the drug GAL‑101, others are placebo. Neither the patient nor the doctor knows which is used until the study ends.
- Time commitment
- The study lasts about 12 months and includes regular eye visits for monitoring and testing.
- Phase 2: a mid-size study of how well it works
- You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance.
