Primary Outcome Measures
NameTimeMethod
Change From Baseline in Geographic Atrophy (GA) Lesion Area of the Study Eye as Assessed by Fundus Autofluorescence (FAF) at Month 24Baseline (Day 1) to Month 24

GA lesion area was measured in mm\^2 by FAF in the study eye and was quantified by the central reading center. The study eye was defined as the eye that met inclusion/exclusion criteria with the worst standard Best Correct Visual Acuity (BCVA). If the BCVA in both eyes was similar the right eye was selected as the study eye. A positive change from baseline indicates an increase in size of GA lesion area (worsening; disease progression). Mixed model for repeated measures (MMRM) was used for analysis.

Secondary Outcome Measures
NameTimeMethod
Change From Baseline in Standard Best Corrected Visual Acuity (BCVA) Score as Assessed by Early Treatment Diabetic Retinopathy Study (ETDRS) Chart at Month 24Baseline (Day 1) to Month 24

BCVA was measured using an eye chart (ETDRS) and was reported as the number of letters read correctly (ranging from 0 to 100 letters) in the study eye. The lower the number of letters read correctly on the eye chart, the worse the vision (or visual acuity). The study eye was defined as the eye that met inclusion/exclusion criteria with the worst standard BCVA. If the BCVA in both eyes was similar the right eye was selected as the study eye. A positive change from baseline indicates an improvement and a negative change from baseline indicates a worsening. MMRM was used for analysis.

Change From Baseline in Low Luminance BCVA Score as Assessed by ETDRS Chart at Month 24Baseline (Day 1) to Month 24

Low Luminance BCVA was measured by placing a 2.0 log unit neutral density filter over the best correction for that eye and having the participant read the normally illuminated ETDRS chart and was reported as the number of letters read correctly (ranging from 0 to 100 letters) in the study eye. The lower the number of letters read correctly on the eye chart, the worse the vision (or visual acuity). The study eye was defined as the eye that met inclusion/exclusion criteria with the worst standard BCVA. If the BCVA in both eyes was similar the right eye was selected as the study eye. A positive change from baseline indicates an improvement and a negative change from baseline indicates a worsening. MMRM was used for analysis.
