简要总结
Study WR42221 is a Phase IIIb, global, multicenter, randomized, visual assessor-masked study designed to assess the efficacy, safety, and pharmacokinetics of the Port Delivery System with ranibizumab (PDS) 100 mg/mL delivered every 36 weeks (Q36W) compared with every 24 weeks (Q24W) in patients with neovascular age-related macular degeneration (nAMD).

- Single (Outcomes Assessor)
盲法说明
- The BCVA examiner will only conduct refraction and BCVA assessments and will be masked to participant study eye assignment and study visit type.
- The BCVA examiner will have no access to a participant's BCVA scores from previous visits and will be aware only of the participant's refraction data from previous visits.
- The BCVA examiner may provide no other direct or indirect participant care.
