KYGEVVI vs WIDAPLIK
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.
WIDAPLIK is a small-molecule inhibitor of cyclin-dependent kinase 12 (CDK12). By selectively inhibiting CDK12, it interferes with the phosphorylation of RNA polymerase II, leading to reduced expression of DNA damage response genes and promoting apoptosis in cancer cells.
5 mg/kg intravenously once every 14 days for 6 cycles, then 5 mg/kg once every 28 days as maintenance therapy.
50 mg orally twice daily.

Terminal elimination half-life is 72 hours (range 60-90 hours) in patients with normal hepatic function, supporting weekly dosing intervals.
Terminal elimination half-life is 12 hours (range 10–14 h) in healthy adults; prolonged to 24–36 h in moderate renal impairment (CrCl 30–50 mL/min).
Primarily hepatic metabolism via CYP3A4, with <1% excreted unchanged in urine. Biliary/fecal elimination accounts for ~90% of metabolites.
Primarily renal excretion as unchanged drug (approximately 70%) with 20% as inactive metabolites; 10% via feces.
