Occurrence of Dose Limiting Toxicity in Part 1 Timeframe: 3 months The number of participants experiencing a dose limiting toxicity corresponding to a category of 3 or greater on the National Cancer Institute Common Terminology Criteria for Adverse Events 2. The Rate of Change in Area of Geographic Atrophy at Month 12 in Participants in Part 2 Timeframe: 12 months The rate of change from baseline in area of GA as measured by fundus autofluorescence at month 12. ### Secondary outcomes 1. Prevention of Vision Loss from Baseline in Participants in Part 2 Timeframe: 12 months Proportion of participants with 15 or greater letter loss in best corrected visual acuity (BCVA) (assessed with the Early Treatment Diabetic Retinopathy Study \\\[ETDRS\\\] visual acuity). Sources for outcomes Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT05839041) ## Eligibility **Sex** All **Age groups** Adults, Older adults **Minimum age** 55 Years **Maximum age** 90 Years **Healthy volunteers** No ### Inclusion criteria Part 1: 1. BCVA in the study eye using ETDRS Chart Visual Acuity Scale (VAS) of 5 to 55 letters (equivalent to Snellen VA of approximately 20/800 - 20/80) 2. If GA is multifocal, at least one focal lesion must be ≥ 1.25 mm2 (0.5 DA) 3. GA may be center involved. Part 2: 1. BCVA in the study eye using ETDRS Chart VAS of 24 letters or better (equivalent to Snellen VA of 20/320 or better) 2. Confirmed diagnosis of AMD that is non-center involving (i.e., non-sub-foveal) GA in 50% of participants. Center involvement allowed in 50% of participants. 3. The entire GA lesion must be completely visualized on the macula centered image and must be able to be imaged in its entirety and not contiguous with any areas of peripapillary atrophy. ### Exclusion criteria Participants are excluded from the study if any of the following criteria apply: Part 1 and 2 \- Presence of the following ocular conditions - in the Study Eye: 1. Exudative AMD or choroidal neovascularization (CNV), including any evidence of retinal pigment epithelium rips or evidence of neovascularization anywhere based on spectral domain optical coherence tomography (SD-OCT) imaging and/or fluorescein angiography as assessed by the Reading Center. 2. Any ocular condition other than GA secondary to AMD that may require surgery or medical intervention during the study period or, in the opinion of the Investigator, could compromise visual function during the study period.
