  3. Presence of intra or sub retinal fluid on SDOCT in the study eye
  4. Current treatment with uninterrupted routine (q35 +/- 7 days) ranibizumab started at least 3 months before Baseline (Week 0), having received at least 3 consecutive ranibizumab injections and no more than 24 injections maximum, with all ranibizumab injection intervals being 35 +/- 7 days apart

  2. Any scarring or fibrosis involving the center of the fovea in the study eye
  3. Prior ocular or systemic treatment/surgery for wet AMD other than ranibizumab IVI monthly (in study the eye)
  4. Prior prn or treat and extend treatment with ranibizumab IVI between 3 to 24 months before Baseline (Week 0) in the study eye
