GLIADEL vs VIVIMUSTA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
VIVIMUSTA is a nitrogen mustard alkylating agent that crosslinks DNA, inhibiting DNA replication and transcription, leading to cell death.
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).
100 mg/m2 intravenously over 30 minutes on days 1-3 of a 21-day cycle.

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.
Terminal elimination half-life is 12 hours (range 10-14 h) in adults with normal renal function; prolonged to 24-36 h in moderate renal impairment (CrCl 30-50 mL/min).
Primarily renal (60-70% as unchanged drug and metabolites) and biliary/fecal (15-20%). Approximately 10-15% is eliminated via exhaled air as CO2.
Renal: 60% unchanged; biliary/fecal: 30% as metabolites; 10% other
