Brief Summary

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

This study will evaluate the efficacy, safety, and PK of ranibizumab 100 milligrams per milliliter (mg/mL) delivered every 24 weeks (Q24W) via the PDS implant compared with ranibizumab 0.5 milligrams (mg) delivered every 4 weeks (Q4W) as intravitreal (IVT) injection in chinese participants with nAMD.

Outcome Assessors

Study Groups

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

Implant Arm

Participants will have the implant (pre-filled intraoperatively with ranibizumab 100 mg/mL) surgically inserted on Day 1. After Day 1, participants in the implant arm will attend monthly study visits, and receive implant refill-exchanges with ranibizumab 100 mg/mL at Week 24 and Week 48. At the Week 48 study visit, participants will move to the long -term extension phase of the study and continue receiving refill-exchanges Q24W until the end of study. Participants will attend monthly visits up to Week 96 and bi-monthly visits, thereafter.

Group Type EXPERIMENTAL

PDS With Ranibizumab (100 mg/mL)

Intervention Type DEVICE

Participants randomized to the implant arm will have the implant (filled prior to implantation with approximately 20 microliters (μL) 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 participants randomized to the IVT arm. After the initial fill of the implant with ranibizumab, participants will receive implant refill-exchanges at fixed 24-week intervals.

IVT Arm

Participants will receive IVT ranibizumab 0.5 mg injections starting on Day 1. Participants will receive IVT ranibizumab 0.5 mg Q4W until Week 44. At the Week 48 study visit, participants will receive the PDS implant (pre-filled intraoperatively with ranibizumab 100 mg/mL), move to the long-term extension phase of the study and receive Q24W refill exchanges until the end of study. If participants are unable to attend the Week 48 visit due to extenuating circumstances, they should return no later than the next scheduled visit (Week 52), when they will receive the PDS implant. Participants will attend monthly visits up to Week 96 and bi-monthly visits, thereafter.

Group Type EXPERIMENTAL

Ranibizumab (10 mg/mL)

Intervention Type DRUG

Participants in the IVT arm will receive their first IVT injection of 50 μL 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, participants will receive IVT ranibizumab injections of 50 μL of the 10 mg/mL formulation Q4W at each scheduled study visit until Week 44.

PDS With Ranibizumab (100 mg/mL)

Participants randomized to the implant arm will have the implant (filled prior to implantation with approximately 20 microliters (μL) 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 participants randomized to the IVT arm. After the initial fill of the implant with ranibizumab, participants will receive implant refill-exchanges at fixed 24-week intervals.

Intervention Type DEVICE

Ranibizumab (10 mg/mL)

Participants in the IVT arm will receive their first IVT injection of 50 μL 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, participants will receive IVT ranibizumab injections of 50 μL of the 10 mg/mL formulation Q4W at each scheduled study visit until Week 44.
