CLOFARABINE vs MARQIBO KIT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Clofarabine is a purine nucleoside antimetabolite that inhibits DNA synthesis by reducing intracellular deoxynucleotide triphosphate pools via inhibition of ribonucleotide reductase, and by terminating DNA chain elongation through incorporation into DNA, leading to apoptosis.
Vinca alkaloid that binds to tubulin, inhibiting microtubule assembly and mitotic spindle formation, causing metaphase arrest in dividing cells.
52 mg/m^2 intravenously over 2 hours daily for 5 consecutive days, repeated every 28 days.
2.25 mg/m2 intravenously over 1 hour every 7 days. Maximum dose per administration is 3.6 mg.

Terminal elimination half-life: 5.2 hours (range 4-6 hours) in adult patients; clinically, this supports a 5-day continuous infusion schedule
Clinical Note
moderateClofarabine + Digoxin
"Clofarabine may decrease the cardiotoxic activities of Digoxin."
Clinical Note
moderateClofarabine + Digitoxin
"Clofarabine may decrease the cardiotoxic activities of Digitoxin."
Clinical Note
moderateClofarabine + Deslanoside
"Clofarabine may decrease the cardiotoxic activities of Deslanoside."
Clinical Note
moderateClofarabine + Acetyldigitoxin
"Clofarabine may decrease the cardiotoxic activities of Acetyldigitoxin."
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: 49-60% as unchanged drug; biliary/fecal: minimal (<1%)
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.
