BYOOVIZ vs VABYSMO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
BYOOVIZ (bevacizumab-maly) is a vascular endothelial growth factor (VEGF) inhibitor that binds to VEGF-A and prevents its interaction with receptors VEGFR-1 and VEGFR-2, thereby inhibiting angiogenesis and tumor growth.
Vabysmo (faricimab) is a bispecific monoclonal antibody that binds to vascular endothelial growth factor-A (VEGF-A) and angiopoietin-2 (Ang-2), inhibiting their activity. By blocking VEGF-A, it reduces endothelial cell proliferation, vascular permeability, and angiogenesis. By inhibiting Ang-2, it stabilizes blood vessels by enhancing pericyte coverage and reducing vascular leakage and inflammation.
0.5 mg (0.05 mL of 10 mg/mL solution) administered by intravitreal injection once every 4 weeks (monthly). Dose adjustment is not recommended.
Intravitreal injection, 6 mg (0.05 mL of 120 mg/mL solution) once every 4 weeks (monthly) for 4 doses, then 6 mg every 8 weeks (2 months) thereafter.

20 days (range 11–50 days) in patients; supports every-2- or 3-week dosing. Longer half-life in bevacizumab compared to other monoclonal antibodies due to FcRn-mediated recycling.
Terminal elimination half-life: approximately 26 days (range 20–36 days) in clinical studies. This supports dosing every 8–16 weeks for neovascular age-related macular degeneration (nAMD) and diabetic macular edema (DME).
Bevacizumab (BYOOVIZ) is eliminated primarily via proteolytic catabolism, not renal or biliary excretion. No significant intact drug is excreted in urine or feces.
Renal elimination: Vabysmo (faricimab) is a monoclonal antibody; it is expected to be degraded into small peptides and amino acids via catabolic pathways. No specific excretion data are available; renal elimination of intact antibody is minimal due to high molecular weight. Biliary/fecal excretion is not a major route.
