Ages Eligible for Study: | 55 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Male or female (non-pregnant, non-lactating) subjects ≥ 55 years
- Standard luminance BCVA score of 34 letters or better using ETDRS charts at the starting distance of 4 meters (approximately 20/200 Snellen equivalent or better) in study eye
-
Clinical diagnosis of GA secondary to AMD:
- Total GA area must be ≥ 2.5 and ≤ 17.5 mm²
- If GA is multifocal, at least one focal lesion must be ≥ 1.25 mm² (0.5 DA), with the overall area of GA ≥ 2.5 and ≤ 17.5 mm²
- Well demarcated GA with no anatomical evidence of current or prior CNV in the study eye
Exclusion Criteria:
Study Eye
- GA secondary to a condition other than AMD in either eye (e.g., monogenetic macular dystrophies like Stargardt disease, cone rod dystrophy, or toxic maculopathies)
- Any history of or active choroidal neovascularization (CNV)
Both Eyes
- Any history of or active bacterial, viral, fungal, or parasitic infection in either eye in the 3 months prior to randomization
