Clinical Trial Summary

Study GR40548 is a Phase III, randomized, multicenter, open-label (visual assessor [VA]-masked), active-comparator study designed to assess the efficacy, safety, and pharmacokinetics (PK) of 100mg/ml delivered via the Port Delivery System with ranibizumab (PDS) compared with ranibizumab intravitreal injections at 0.5 mg (10 mg/mL) in participants with neovascular age-related macular degeneration (nAMD).

• Current systemic treatment for a confirmed active systemic infection
• Chronic use of oral corticosteroids
• Active cancer within 12 months of randomization
• Previous participation in any non-ocular (systemic) disease studies of investigational drugs within 1 month preceding the informed consent (excluding vitamins and minerals)
