A Study to Investigate Safety, Tolerability, Pharmacokinetics (PK), Pharmacodynamics (PD), and Immunogenicity of RO7669330 in Participants With Geographic Atrophy (GA) Secondary to Age-related Macular Degeneration (AMD)

Inclusion Criteria: * Adequately clear ocular media, adequate pupillary dilation, and fixation to allow acquisition of good quality fundus imaging * GA that resides completely within the fundus autofluorescence (FAF) imaging field * Presence of hyperautofluorescence of either banded or diffuse pattern adjacent to the GA area on FAF * Study eye has early treatment of diabetic retinopathy study (ETDRS) best-corrected visual acuity (BCVA) score as follows: * Part 1A: 19 to 48 letters, inclusively * Part 1B: \> 19 letters * Part 2: ≥ 24 letters * Total GA lesion size must be as follows: * Parts 1A and 1B: ≥ 1.25 square millimeter (mm\^2) and ≤ 20 mm\^2 ) * Part 2: ≥ 2.5 mm\^2 and ≤ 20 mm\^2 Exclusion Criteria: Ocular Exclusion Criteria for the Study Eye: * Aphakic or pseudophakic with intraocular lens outside of the capsular bag * Previous laser photocoagulation or IVT anti-vascular endothelial growth factor (VEGF) for CNV, diabetic macular edema (DME), retinal vein occlusion (RVO), or proliferative diabetic retinopathy * Active or history of CNV Ocular Exclusion Criteria for the Non-Study Eye: \- Non-functioning non-study eye, defined as either: BCVA of hand motion or worse and/or no physical presence of eye Ocular Exclusion Criteria for Both Eyes: * Macular atrophy in either eye due to causes other than AMD * Part 2: Evidence of prior or active CNV * Prior treatment with any approved therapy for GA (Syfovre, Izervay) in either eye for Part 1A and Part 2 ≤ 20 weeks prior…
