KYGEVVI vs REDEMPLO
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.
REDEMPLO is a synthetic tricyclic analog that acts as a selective serotonin-norepinephrine-dopamine reuptake inhibitor (SNDRI). It binds to the presynaptic transporters for serotonin (SERT), norepinephrine (NET), and dopamine (DAT), inhibiting their reuptake and increasing synaptic concentrations of these monoamines. Additionally, it has weak antagonistic properties at the 5-HT2A and alpha-2 adrenergic receptors, contributing to its antidepressant and anxiolytic effects.
5 mg/kg intravenously once every 14 days for 6 cycles, then 5 mg/kg once every 28 days as maintenance therapy.
100 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.
Terminal elimination half-life is 12-15 hours in healthy adults; prolonged in hepatic impairment (up to 30 hours) and end-stage renal disease (up to 40 hours).
Primarily hepatic metabolism via CYP3A4, with <1% excreted unchanged in urine. Biliary/fecal elimination accounts for ~90% of metabolites.
Primarily hepatic metabolism with 70% renal excretion of metabolites and 30% fecal elimination; less than 5% excreted unchanged in urine.
