KYGEVVI vs LERIBANE
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.
Leribane is a synthetic cannabinoid receptor agonist with high affinity for CB1 and CB2 receptors. It inhibits adenylate cyclase activity via Gi/o protein coupling, leading to decreased cAMP accumulation, modulation of ion channels, and inhibition of neurotransmitter release.
5 mg/kg intravenously once every 14 days for 6 cycles, then 5 mg/kg once every 28 days as maintenance therapy.
5-10 mg orally twice daily; maximum 30 mg/day.

Terminal elimination half-life is 72 hours (range 60-90 hours) in patients with normal hepatic function, supporting weekly dosing intervals.
24 hours (range 20-30 h); accumulates to steady state in ~5 days, requires dose adjustment in renal impairment
Primarily hepatic metabolism via CYP3A4, with <1% excreted unchanged in urine. Biliary/fecal elimination accounts for ~90% of metabolites.
Renal: 70% unchanged; biliary/fecal: 30% as metabolites
