Description of intervention(s) / exposure
Treatment: Drugs - Vamikibart
Other interventions - Sham

Experimental: Arm A - Participants will receive 4 low-dose vamikibart intravitreal (IVT) injections every 4 weeks (Q4W) to Week 12, followed by as-needed (PRN) dosing from Week 20 to Week 48.

Experimental: Arm B - Participants will receive 4 high-dose vamikibart IVT injections Q4W to Week 12, followed by PRN dosing from Week 20 to Week 48.

Sham comparator: Arm C - Participants will receive 4 sham injections Q4W to Week 12, followed by PRN sham dosing from Week 20 to Week 48.


Treatment: Drugs: Vamikibart
Participants will receive vamikibart IVT injection

Other interventions: Sham
Participants will receive a sham procedure that mimics an IVT injection.
