Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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).

Blinding Strategy

SINGLE

Outcome Assessors
* 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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Arm A [Q36W] 36-weeks between refill-exchange procedures

Inclusion Criteria

* Age ≥ 50 years at time of signing Informed Consent Form

* Previous treatment with corticosteroid intravitreal injection, intraocular device implantation, previous laser (any type) used for AMD treatment in study eye
* Treatment with anti-VEGF agents other than ranibizumab within 1 month prior to the enrollment visit in study eye
* Concurrent conjunctival, Tenon's capsule, and/or scleral condition in the supero-temporal quadrant of the eye that may affect the implantation, subsequent tissue coverage, and refill-exchange procedure of the PDS implant
* Prior treatment with brolucizumab (at any time prior to the screening visit) in either eye
* Prior participation in a clinical trial involving any anti-VEGF drugs, within 9 months prior to the enrollment visit in either eye
* Subretinal hemorrhage that involves the center of the fovea, if the hemorrhage is \>0.5 disc area at screening in study eye
* Subfoveal fibrosis or subfoveal atrophy in study eye
* Choroidal neovascularization (CNV) due to other causes, such as ocular histoplasmosis, trauma, central serous chorio-retinopathy, or pathologic myopia in either eye
* Retinal pigment epithelial tear in study eye
* Any concurrent intraocular condition that would either require surgical intervention during the study to prevent or treat visual loss that might result from that condition or affect interpretation of study results in study eye
