KYGEVVI vs ZUSDURI
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
KygeVVI is a fusion protein that acts as a decoy receptor for vascular endothelial growth factor (VEGF), binding to VEGF-A and VEGF-B and placental growth factor (PlGF), thereby inhibiting angiogenesis and tumor growth.
ZUSDURI is a small molecule inhibitor of Janus kinase 1 (JAK1) and Janus kinase 2 (JAK2), reducing signaling of pro-inflammatory cytokines.
5 mg/kg intravenously once every 14 days for 6 cycles, then 5 mg/kg once every 28 days as maintenance therapy.
200 mg orally once daily, with or without food.

Terminal elimination half-life is 72 hours (range 60-90 hours) in patients with normal hepatic function, supporting weekly dosing intervals.
The terminal elimination half-life is approximately 12–15 hours in healthy adults, supporting twice-daily dosing. In patients with hepatic impairment, half-life may be prolonged up to 24 hours, requiring dose adjustment.
Primarily hepatic metabolism via CYP3A4, with <1% excreted unchanged in urine. Biliary/fecal elimination accounts for ~90% of metabolites.
ZUSDURI is primarily eliminated via hepatic metabolism with subsequent biliary excretion. Approximately 30% of the dose is excreted unchanged in feces, and less than 5% is recovered unchanged in urine. The major metabolites are excreted in bile and eliminated in feces.
