HEPZATO vs OXALIPLATIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
HEPZATO (melphalan) is a nitrogen mustard alkylating agent that crosslinks DNA strands, inhibiting DNA replication and transcription, leading to cell death.
Oxaliplatin is a platinum-based alkylating agent that forms inter- and intrastrand DNA crosslinks, inhibiting DNA replication and transcription, leading to cell death.
Melphalan 3 mg/kg ideal body weight via hepatic artery infusion over 15-30 minutes followed by hemofiltration, administered once per treatment cycle.
85 mg/m² intravenously over 2 hours every 2 weeks in combination with 5-fluorouracil and leucovorin (FOLFOX regimen).

The terminal elimination half-life of melphalan is approximately 1.5 hours following intravenous administration. This short half-life necessitates regional delivery (hepatic arterial infusion) to achieve high local concentrations with limited systemic exposure.

Terminal elimination half-life is approximately 40-50 hours for ultrafilterable platinum (active species) and 240-500 hours for total platinum (bound to plasma proteins and erythrocytes). The prolonged half-life reflects slow release from tissue binding.
HEPZATO (melphalan hydrochloride) for injection is renally eliminated; approximately 20-30% of the administered dose is excreted unchanged in the urine over 24 hours. The major metabolites are hydrolysis products, which are also excreted renally. Biliary/fecal elimination accounts for less than 10% of the dose.
Renal excretion accounts for approximately 50% of the administered platinum, with the remainder eliminated via biliary/fecal routes. Platinum accumulates in erythrocytes and is slowly cleared.
