SUSVIMO vs VABYSMO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ranibizumab is a humanized monoclonal antibody fragment that binds to and inhibits the activity of vascular endothelial growth factor A (VEGF-A), thereby reducing angiogenesis and vascular permeability.
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.
10 mg administered via intravitreal injection every 4 weeks for the first 3 doses, then every 8 weeks thereafter.
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.

Terminal elimination half-life is approximately 4.9 days (range 3.5–6.7 days) in patients receiving intravitreal injections every 4 weeks. The long half-life supports sustained intravitreal VEGF suppression with monthly dosing.
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).
Primarily metabolized in the liver via catabolism to small peptides and amino acids; renal elimination of metabolites is negligible as intact drug is not excreted renally. Biliary/fecal excretion is not a significant route. <1% of dose excreted unchanged in urine.
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.
