A Study to Evaluate Intravitreal JNJ-81201887 (AAVCAGsCD59) Compared to Sham Procedure for the Treatment of Geographic Atrophy (GA) Secondary to Age-related Macular Degeneration (AMD)

Change From Baseline in Functional Reading Independence (FRI) Index at Month 18

The FRI is an interviewer-administered questionnaire with 7 items on functional reading activities most relevant to GA AMD participants. Item scores reflect decreasing levels of functional reading independence. The FRI Index yields continuous mean scores (range 1 to 4), and ordinal-level scores from Level 1 = "Unable to do" to Level 4 = "Totally independent." For each FRI Index reading activity performed in the past 7 days, participants are asked about the extent to which they required vision aids, adjustments in the activity, or help from another person.
