AVZIVI vs SUSVIMO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Avizivi (avelumab) is a human IgG1 monoclonal antibody that binds to programmed death-ligand 1 (PD-L1), blocking its interaction with PD-1 and CD80 receptors. This restores anti-tumor immune responses, including T-cell activation and proliferation, by reversing PD-L1-mediated inhibition.
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.
IV 200 mg over 30 minutes on Day 1 of a 21-day cycle, in combination with paclitaxel and carboplatin; continue until disease progression or unacceptable toxicity.
10 mg administered via intravitreal injection every 4 weeks for the first 3 doses, then every 8 weeks thereafter.

Terminal elimination half-life is approximately 12 hours (range 10–14 h) in patients with normal renal function; prolonged to 24–48 h in moderate-to-severe renal impairment.
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.
Primarily renal excretion as unchanged drug (~70%) and glucuronide conjugate (~30%); biliary/fecal excretion accounts for <5%.
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.
