MARQIBO KIT vs NELARABINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Vinca alkaloid that binds to tubulin, inhibiting microtubule assembly and mitotic spindle formation, causing metaphase arrest in dividing cells.
Nelarabine is a prodrug of ara-G, a deoxyguanosine analog. It is converted to ara-GTP, which accumulates in T-cells and inhibits DNA synthesis, leading to cell death.
2.25 mg/m2 intravenously over 1 hour every 7 days. Maximum dose per administration is 3.6 mg.
1500 mg/m2 intravenously over 2 hours on days 1, 3, and 5, repeated every 28 days.

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.
Clinical Note
moderateNelarabine + Digoxin
"Nelarabine may decrease the cardiotoxic activities of Digoxin."

"Nelarabine may decrease the cardiotoxic activities of Deslanoside."
Clinical Note
moderateNelarabine + Acetyldigitoxin
"Nelarabine may decrease the cardiotoxic activities of Acetyldigitoxin."
Terminal t1/2: 30 hours (range 21-48 h) in adults; prolonged in renal impairment. Ara-G (active metabolite) t1/2: 3 hours.
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.
Renal: 50-60% as unchanged ara-G; fecal: <5% as metabolites; biliary: negligible.
