Clinical Data
The year two HAWK and HARRIER findings demonstrated that fewer patients with nAMD had intra-retinal fluid (IRF) and/or sub-retinal fluid (SRF) - key markers used by physicians to determine injection frequency in clinical practice - with brolucizumab 6 mg versus aflibercept at week 96 [24% for brolucizumab 6 mg vs. 37% for aflibercept in HAWK (P=0.0001); 24% vs. 39%, respectively, in HARRIER (P<0.0001)][1]*.Additionally, brolucizumab 6 mg patients continued to demonstrate reductions in central subfield thickness (CST) at week 96[1]. An increase in CST in nAMD is an important measure of abnormal fluid accumulation and edema and may result in reduced vision. Absolute reductions in CST from baseline were -175 µm for brolucizumab 6 mg versus -149 µm for aflibercept in HAWK (P=0.0057) and -198 µm versus -155 µm, respectively, in HARRIER (P<0.0001)[1]*.Also at week 96, fewer brolucizumab 6 mg patients had sub-retinal pigment epithelium (sub-RPE) fluid (11% for brolucizumab 6 mg vs. 15% for aflibercept in HAWK; 17% vs. 22%, respectively, in HARRIER)[1]. Additionally, of the patients on brolucizumab 6 mg who successfully completed year one on a 12-week dosing interval, 82% in HAWK and 75% in HARRIER were maintained on a 12-week dosing interval in year two[1].
