Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Age >/= 60 years at time of signing Informed Consent Form;
- Visual acuity: best-corrected visual acuity (BCVA) letter score >/= 24 letters (Snellen equivalent of 20/320 or better).

- Well-demarcated area of GA secondary to AMD with no evidence of prior or active choroidal neovascularization (CNV) in either eye.
Exclusion Criteria:
Ocular Exclusion Criteria, Study Eye:
- History of vitrectomy surgery, submacular surgery, or any surgical intervention for AMD;
- Previous laser photocoagulation or ITV anti-vascular endothelial growth factor (anti-VEGF) for CNV, diabetic macular edema, retinal vein occlusion, or proliferative diabetic retinopathy.
Ocular Exclusion Criteria, Both Eyes:
- GA in either eye due to causes other than AMD;
- Active uveitis and/or vitritis (grade trace or above) in either eye;
- Active, infectious conjunctivitis, keratitis, scleritis, or endophthalmitis in either eye;
- Retinal pigment epithelium (RPE) tear that involves the macula in either eye;
- Previous participation in interventional clinical trials for GA or dry AMD, except for vitamins and minerals, regardless of the route of administration (i.e., ocular or systemic) within the last 6 months.
