Clinical Trial Summary

This was a 64-week randomized, double-masked, multi-center, active-controlled, two-arm study in patients with neovascular age related macular degeneration (nAMD) who have not previously received anti- vascular endothelial growth factor (VEGF) treatment.

Description:

At the baseline Visit, subjects who met the eligibility criteria were randomized in a 1:1 ratio to receive either: -Brolucizumab 6 mg: 3 × 4-week injections and one 8-week injection, followed by Treat-to- Control treatment from Week 16 up to Week 60/62

-Aflibercept 2 mg: 3 × 4-week injections and one 8-week injection, followed by Treat-to-Control treatment from Week 16 up to Week 60/62.

For all subjects, the last potential study treatment was at the Week 60 visit (or at the Week 62 visit for subjects whose actual treatment interval would require a treatment at Week 62). The initiation phase starts on Day 1 and ends on Week 16. Treat to Control regimen starts on Week 16 until end of treatment (Week 60/62).

In both treatment arms, treatment intervals after the initiation phase were either 8 weeks, 12 weeks, or 16 weeks. Per the original protocol, if it was determined that a patient required more frequent injections than q8w, he/she would be moved to a q4w treatment interval. However, this option was removed per Protocol amendment 02, after which, dosing intervals shorter than q8w were not permitted.
