Primary Outcome Measures:
  • Change in GA area, as assessed by retinal imaging [ Time Frame: From baseline to Week 48 ]

Secondary Outcome Measures:
  • Mean change from baseline in BCVA at 2 years as assessed by ETDRS chart under low luminance conditions at a starting distance of 4 meter (m) [ Time Frame: From baseline to 2 years ]
  • Mean change from baseline in BCVA over time as assessed by ETDRS chart under low luminance conditions at a starting distance of 4 m [ Time Frame: from baseline to 2 years ]
  • Mean change from baseline in mean binocular reading speed at 2 years as assessed by MNRead charts or Radner Reading Charts [ Time Frame: From baseline to Week 48 ]
  • Mean change from baseline in FRI Index score at 2 years [ Time Frame: From baseline to 2 years ]
