Outcome results
Percentage of Subjects With a ≥ 3-line Gain in BDCVA (Best Distance-Corrected Visual Acuity) at 40cm and no Loss in BDCVA ≥ 5 Letters at 4m on Day 8, 1 Hour Post-Dose 1.
The primary end-point was measured on Day 8, 1 hour post first CSF-1 dose, as the number of participants who are responders to the treatment. A responder was defined as as subject with a ≥ 3-line gain in BDCVA (Best Distance-Corrected Visual Acuity) at 40cm and no loss in BDCVA ≥ 5 letters at 4m.
Time frame: Baseline (Day 1) to Day 8 (1 hour post-Dose 1)
Population: Full analysis set (FAS): included all randomized subjects who received at least 1 dose of the study drug. Subjects in the FAS were analyzed as randomized.
