Brolucizumab licence application to treat wet age-related macular degeneration
Novartis announced that the FDA accepted the company's Biologics License Application (BLA) for brolucizumab (RTH 258) for the treatment of wet age-related macular degeneration (AMD), also known as neovascular AMD, or nAMD. Seeking to make brolucizumab available as quickly as possible, Novartis used a priority review voucher to expedite FDA review. If approved by the FDA, Novartis anticipates launching brolucizumab by the end of 2019.
The regulatory application is primarily based on Phase III data from the HAWK and HARRIER trials - prospective, randomized, double-masked multi-center studies. The primary endpoint of these studies was non-inferiority to aflibercept in mean change in best-corrected visual acuity (BCVA) from baseline to week 48 (mean change in BCVA of 6.6 letters for brolucizumab 6 mg versus 6.8 letters for aflibercept in HAWK and 6.9 letters versus 7.6 letters, respectively, in HARRIER). HAWK and HARRIER are the first and only global head-to-head trials in patients with wet AMD that prospectively demonstrated efficacy at week 48 starting with a 12-week dosing regimen. Additionally, at week 48 in the studies, key secondary endpoint assessments showed significantly fewer brolucizumab patients with disease activity (23.5% of brolucizumab 6 mg patients versus 33.5% of aflibercept patients in HAWK, and 21.9% versus 31.4%, respectively, in HARRIER (P=0.0022 for both) as well as retinal fluid - key markers used by physicians to help guide management of the disease in clinical practice (31% fewer patients on brolucizumab 6 mg had intra-retinal fluid (IRF) and/or sub-retinal fluid (SRF) in HAWK, and 26% fewer in HARRIER, versus aflibercept (P<0.0001 for both).
