KYGEVVI vs LEQSELVI
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.
LEQSELVI is a selective estrogen receptor degrader (SERD) that binds to estrogen receptors (ER), inducing their degradation and blocking ER-mediated signaling.
5 mg/kg intravenously once every 14 days for 6 cycles, then 5 mg/kg once every 28 days as maintenance therapy.
LEQSELVI is not a recognized pharmaceutical name. No dosing information available.

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 approximately 12 hours in healthy adults; may be prolonged in patients with moderate to severe hepatic impairment.
Primarily hepatic metabolism via CYP3A4, with <1% excreted unchanged in urine. Biliary/fecal elimination accounts for ~90% of metabolites.
Primarily excreted as unchanged drug via renal elimination (approximately 70% of dose), with biliary/fecal excretion accounting for about 20%.
