Study of the Efficacy and Safety of the Ranibizumab Port Delivery System for Sustained Delivery of Ranibizumab in Patients With Subfoveal Neovascular Age-Related Macular Degeneration

Summary

This is a Phase II multicenter, dose-ranging, randomized, active treatment (monthly ITV injection)-controlled study to evaluate the efficacy, safety, and pharmacokinetics of ranibizumab delivered through the Implant using three ranibizumab formulation arms (10 mg/mL, 40 mg/mL, and 100 mg/mL) compared with the control arm (0.5-mg monthly ITV injections of 10-mg/mL formulation) in participants with subfoveal neovascular age-related macular degeneration (nAMD).
