Primary Outcome Measures:
  • Mean annualized lesion enlargement rate from baseline [ Time Frame: Baseline, up to Month 30 ] [ Designated as safety issue: No ]
    As assessed with fundus autofluorescence imaging


Secondary Outcome Measures:
  • Mean change in best-corrected visual acuity (BCVA) from baseline to last visit [ Time Frame: Baseline, up to Month 30 ] [ Designated as safety issue: Yes ]
    As assessed with the Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity protocol

  • Mean change in National Eye Institute Visual Functioning Questionnaire (NEI VFQ-25) Quality of Life Instrument Scores from Baseline to Last Visit [ Time Frame: Baseline, up to Month 30 ] [ Designated as safety issue: No ]
    Validated visual function questionnaire used for collecting quality of life data from patients with age-related macular degeneration.
