VIVIMUSTA vs ZEPZELCA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
VIVIMUSTA is a nitrogen mustard alkylating agent that crosslinks DNA, inhibiting DNA replication and transcription, leading to cell death.
Lurbinectedin is a selective inhibitor of oncogenic transcription. It binds to the minor groove of DNA, inhibiting the activity of RNA polymerase II and promoting its degradation, thereby reducing transcription of certain oncogenes and inducing apoptosis in cancer cells.
100 mg/m2 intravenously over 30 minutes on days 1-3 of a 21-day cycle.
3.24 mg/m2 intravenously over 60 minutes every 21 days until disease progression or unacceptable toxicity.

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).
Terminal elimination half-life is approximately 7-9 hours in patients with normal hepatic function, supporting once-daily dosing.
Renal: 60% unchanged; biliary/fecal: 30% as metabolites; 10% other
Primarily hepatic metabolism, with biliary/fecal excretion as the major route (approximately 60-80% of the administered dose). Renal excretion accounts for <20% of the dose as unchanged drug and metabolites.
