EVOMELA vs GLIADEL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
EVOMELA (melphalan) is a bifunctional alkylating agent that forms cross-links between DNA strands, inhibiting DNA replication and transcription, leading to cell death.
GLIADEL (carmustine implant) is a biodegradable wafer that delivers carmustine, a nitrosourea alkylating agent, directly into the tumor resection cavity. Carmustine alkylates DNA and RNA, leading to cross-linking and inhibition of DNA replication, ultimately causing cell death. It is cell cycle phase nonspecific.
140-200 mg/m² IV over 30 minutes for conditioning prior to ASCT; off-label: 16 mg/m² IV over 15-20 minutes every 4 weeks for MM.
Gliadel (carmustine) implant is administered intraoperatively as 8 wafers, each containing 7.7 mg carmustine, placed in the resection cavity after tumor debulking. Maximum dose is 61.6 mg (8 wafers).

Terminal elimination half-life is approximately 75 minutes (range 40-120 minutes) in patients with normal renal function; prolonged to 180-300 minutes in renal impairment
Terminal elimination half-life is approximately 1.3 hours for the active dianhydrogalactitol metabolite. Clinical context: short half-life supports local interstitial delivery with minimal systemic accumulation.
Primarily renal: approximately 10-30% of unchanged drug excreted in urine within 24 hours; extensive hepatic metabolism; fecal excretion accounts for <5%
Primarily renal (60-70% as unchanged drug and metabolites) and biliary/fecal (15-20%). Approximately 10-15% is eliminated via exhaled air as CO2.
