CLOFARABINE vs HALAVEN
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.
Halaven (eribulin mesylate) is a microtubule dynamics inhibitor. It binds to tubulin, suppressing microtubule growth and sequestering tubulin into nonfunctional aggregates, leading to G2/M cell cycle arrest and apoptosis.
52 mg/m^2 intravenously over 2 hours daily for 5 consecutive days, repeated every 28 days.
1.4 mg/m2 intravenously over 2-5 minutes on days 1 and 8 of a 21-day cycle.

Terminal elimination half-life: 5.2 hours (range 4-6 hours) in adult patients; clinically, this supports a 5-day continuous infusion schedule
Terminal elimination half-life approximately 30-50 hours (mean 40 hours). Clinically, this supports weekly dosing schedule.
Renal: 49-60% as unchanged drug; biliary/fecal: minimal (<1%)
Primarily biliary/fecal: ~70-80% as unchanged drug and metabolites in feces; renal excretion accounts for <10% (mostly metabolites).
