Eligibility Criteria

• 3. Barrier method (e.g., condom or occlusive cap) with spermicidal foam/gel/film/cream AND either hormonal contraception (oral, implanted, or injectable) or an intrauterine device or system Note: Non-childbearing potential is defined as surgical sterilization (e.g., bilateral oophorectomy, hysterectomy, or tubal ligation) or postmenopausal (defined as permanent cessation of menstruation for at least 12 consecutive months prior to the Screening Visit).
• 10. Male subjects with female partners of childbearing potential must be willing to use a highly effective method of contraception (e.g., abstinence, dual method of contraception) from the date they sign the ICF until 28 days after the last dose of IMP
• 1. The absence of observable hyper-FAF at the margins of the GA in the study eye at the Screening Visit by the Reading Center
• 2. Atrophic retinal disease of causality other than AMD including myopia-related maculopathy and monogenetic macular dystrophies including pattern dystrophy and adult-onset Stargardt disease in the study eye
• 3. Evidence of exudative AMD or CNV by history or FA in the study eye, as determined by the Reading Center
• 4. Presence of retinal vein occlusion in the study eye
• 5. Presence of vitreous hemorrhage in the study eye
• 6. History of retinal detachment in the study eye
• 7. History of macular hole (stages 2 to 4) in the study eye
• 8. Presence of an epiretinal membrane and/or vitreomacular traction in the study eye that causes distortion of the retinal contour
• 9. Presence of any retinal pathology in the study eye that prohibits outer retinal quantification and EZ mapping, as determined at the Screening Visit by the Reading Center
• 10. At the Screening Visit, advanced glaucoma resulting in a cup to disc ratio of \> 0.8 in the study eye
• 11. History of glaucoma filtration surgery or uncontrolled glaucoma at Baseline Visit in the opinion of the Investigator OR currently using \> 2 medications (Minimally invasive glaucoma surgeries (e.g., MIGS) are allowable) Note: Combination medications count as 2 medications.
• 12. Presence of visually significant cataract OR presence of significant posterior capsular opacity in the setting of pseudophakia Note: Significant cataract is defined as \> +2 nuclear sclerosis based upon the scale below or any Posterior Subcapsular Cataract in the study eye. The Sponsor, or its designee, will supply the clinical trial sites with a copy of the standard photographs. Grade Description
• * 1 Opacity is absent
• * 2 Opacity is present, but less than Nuclear Standard Photograph #2
• * 3 Opacity is present, and as severe as or worse than Nuclear Standard Photograph #2 Source: (Chew 2010)
• 13. Presence of significant keratopathy or any other media or corneal opacity that would cause scattering of light or alter visual function, especially in LL conditions in the study eye
• 14. Ocular incisional or laser surgery (including cataract surgery) in the study eye within 90 days before the Baseline Visit
• 15. YAG laser capsulotomy in the study eye within 30 days before the Baseline Visit
• 16. Aphakia in the study eye
• 17. History of vitrectomy surgery, submacular surgery, or any vitreoretinal surgery in the study eye
• 18. Prior treatment with Visudyne® (verteporfin) ocular photodynamic therapy, external-beam radiation therapy (for intraocular conditions), or transpupillary thermotherapy in the study eye
• 19. History of subthreshold laser treatment or other forms of photobiomodulation for AMD in the study eye
• 20. Intravitreal drug delivery in the past 60 days or 5-half-lives from the Baseline Visit of the injected drug whichever is longer (e.g., intravitreal corticosteroid injection, anti-angiogenic drugs, or device implantation) in the study eye
