Study Design


Related Conditions & MeSH terms


Intervention

Device:
PDS with ranibizumab (100 mg/mL)
Patients randomized to the implant arm will have the implant (filled prior to implantation with approximately 20 uL of the 100-mg/mL formulation of ranibizumab [approximately 2 mg dose of ranibizumab]) surgically inserted in the study eye at the Day 1 visit following their randomization visit, or at Week 48 visit for patients randomized to the intravitreal arm. After the initial fill of the implant with ranibizumab, patients will receive implant refill-exchanges at fixed 24-week intervals.
Drug:
Ranibizumab (10 mg/mL)
Patients in the intravitreal arm will receive their first intravitreal injection of 50 uL of the 10 mg/mL ranibizumab (0.5 mg dose) at the Day 1 visit, which will occur at the conclusion of the randomization visit. Afterward, patients will receive intravitreal ranibizumab injections of 50 uL of the 10 mg/mL formulation Q4W at each scheduled study visit until Week 44
