About this study

The purpose of this study is to measure the change in Best-corrected visual acuity (BCVA) with brolucizumab 6 mg Personalized regimen compared with Brolucizumab 6 mg Standard q12w/q8w regimen in participants with Polypoidal choroidal vasculopathy (PCV).

  • The study duration will be up to 60 weeks.
  • The treatment duration will be up to 56 weeks.
  • The visit frequency is not fixed and may be reduced or extended depending on whether disease activity is controlled.

In the Personalized regimen arm, the first loading injection will be performed for all participants. After 4 weeks, treatment response will be judged. If there is no disease activity, injection interval will be extended to 8 weeks. The participants with presence of disease activity will continue 4-week loading injections up to 3 monthly loading dose and commence the Treat-and-extend (T&E) phase thereafter. In the T&E phase, the treatment interval can be extended by 4 weeks at a time based on Investigator's judgment of visual and/or anatomic outcomes. The maximal treatment interval is 16 weeks. At the Investigator's discretion, a participant with no disease activity or improvement of disease activity (e.g., reduction of fluid) may also be maintained on the same interval. If disease activity recurs, the interval should be shortened by 4 weeks at a time or to a minimal interval of 8 weeks.

In the Standard q12w/q8w regimen arm, all participants will receive three loading injections every 4 weeks. After loading injection, participants with no disease activity at Week 16 will receive study treatment q12w at Week 20, Week 32, and Week 44. If there is disease activity at any scheduled treatment visit, the study intervals will be adjusted to 8 weeks thereafter. Treatment intervals can be increased to 12 weeks after a treatment visit with no disease activity.
