PYZCHIVA vs SUSVIMO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Biosimilar to infliximab; a chimeric monoclonal antibody that binds to human tumor necrosis factor alpha (TNFα), neutralizing its activity and reducing inflammation.
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.
Intravenous infusion of 300 mg over 60 minutes on days 1, 15, and 29, then every 4 weeks thereafter.
10 mg administered via intravitreal injection every 4 weeks for the first 3 doses, then every 8 weeks thereafter.

Terminal elimination half-life approximately 21-25 days (mean 23 days), consistent with IgG1 monoclonal antibody clearance; supports monthly dosing.
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 eliminated via the reticuloendothelial system; renal excretion of intact drug is negligible (<1%). Biliary/fecal excretion accounts for <5% as intact drug.
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.
