Summary
Brief summary
The purpose of this extension study was to evaluate the efficacy and safety of brolucizumab used in a Treat-to-Control-regimen for treatment of patients with neovascular age-related macular degeneration who have completed the CRTH258A2303 (TALON) study. The main objective was to assess brolucizumab's potential for long durability up to 20 weeks.

All eligible participants were treated with brolucizumab regardless of their treatment in the TALON study.

The study period was 56 weeks including post-treatment follow-up.
