CLADRIBINE vs MARQIBO KIT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cladribine is a purine nucleoside analog that is phosphorylated intracellularly to its active triphosphate form, which inhibits DNA synthesis and repair, leading to cell death, particularly in lymphocytes. It also depletes adenosine deaminase (ADA) and accumulates in cells with high deoxycytidine kinase activity.
Vinca alkaloid that binds to tubulin, inhibiting microtubule assembly and mitotic spindle formation, causing metaphase arrest in dividing cells.
0.09 mg/kg/day IV over 2 hours for 7 consecutive days; or 0.14 mg/kg/day IV over 2 hours for 5 consecutive days (total dose 0.7 mg/kg per course).
2.25 mg/m2 intravenously over 1 hour every 7 days. Maximum dose per administration is 3.6 mg.

Terminal elimination half-life is approximately 5.4 hours (range 4.6–6.7 hours) after intravenous administration; prolonged in renal impairment.
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 (approximately 50% as unchanged drug); fecal elimination is minimal (<5%).
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.
