Faricimab: from research to clinical practice

Abstract

Development of new molecules for anti-angiogenic therapy pursues the following objectives: to increase the interval between injections, which can reduce the treatment burden; to improve the effectiveness of treatment by affecting various links of pathogenesis; to ensure a good safety profile. Faricimab is a humanized immunoglobulin G antibody that targets two key angiogenesis sites: vascular endothelial growth factor A (VEGF-A) and angiopoietin-2 (Ang-2). In the STAIRWAY clinical trial, faricimab was shown to produce similar results to monthly ranibizumab at longer intervals and fewer intravitreal injections in patients with neovascular age-related macular degeneration, specifically in terms of visual preservation and reduction in central retinal thickness (CRT). In the BOULEVARD trial, which lasted 36 weeks, the severity of diabetic retinopathy according to DRSS improved in previously untreated patients with diabetic macular edema by two stages and more in 12.2% of the 0.3 mg ranibizumab group, in 27.7% of patients in the 1.5 mg faricimab group, and in 38.6% of patients in the group treated with 6.0 mg faricimab. In the TENAYA, as well as LUCERNE, YOSEMITE and RHINE trials, the increase in best-corrected visual acuity (BCVA) from baseline in the faricimab group was comparable to that in the aflibercept group. Real clinical practice showed an increase in BCVA from 59.5 to 60.6 letters (p=0.035) due to a decrease in CRT from 334.3 to 303.3 µm (p=0.001). The first published studies are now appearing, and their results correspond to the clinical trials, which indicates a stable effect of the drug and the prospects for use in a large cohort of patients.
