IDVYNSO vs MARQIBO KIT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
IDVYNSO is a selective dopamine D3 receptor antagonist, which modulates dopaminergic neurotransmission in the mesolimbic pathway.
Vinca alkaloid that binds to tubulin, inhibiting microtubule assembly and mitotic spindle formation, causing metaphase arrest in dividing cells.
5 mg/kg IV once daily for 14 days; then 2.5 mg/kg IV once daily for 14 days.
2.25 mg/m2 intravenously over 1 hour every 7 days. Maximum dose per administration is 3.6 mg.

Terminal elimination half-life is 12–18 hours, supporting twice-daily dosing in patients with normal renal function.
Terminal elimination half-life ranges from 19 to 40 hours (mean 23 hours) in adults. The prolonged half-life in Marqibo (liposomal vincristine) is due to the sustained release from the liposomal formulation, allowing once-weekly dosing.
Renal excretion of unchanged drug accounts for approximately 60% of elimination; biliary/fecal excretion accounts for 30%, with the remainder metabolized.
Primarily hepatobiliary excretion; approximately 5-16% of the dose is excreted unchanged in the urine over 72 hours. Fecal excretion accounts for about 10% of the administered dose, with the remainder undergoing extensive hepatic metabolism and biliary elimination.
