CLOFARABINE vs PARAPLATIN
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.
Carboplatin, a platinum-based alkylating agent, forms interstrand and intrastrand DNA cross-links by binding to DNA guanine bases, inhibiting DNA replication and transcription, leading to cell cycle arrest and apoptosis.
52 mg/m^2 intravenously over 2 hours daily for 5 consecutive days, repeated every 28 days.
360 mg/m2 IV every 3 weeks or area under the curve (AUC) 4-6 mg/mL/min IV every 3-4 weeks using Calvert formula.

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: 2.6-5.1 hours (initial phase), 22-52 hours (terminal phase) for total platinum; 1.3-2.1 hours for ultrafilterable platinum. Clinically, the terminal half-life reflects slow release of protein-bound platinum.
Renal: 49-60% as unchanged drug; biliary/fecal: minimal (<1%)
Renal excretion: ~70-90% of platinum is excreted in urine within 24 hours, primarily as unchanged drug. Fecal excretion: <6%. Biliary excretion: minimal.
