Zepzelca Disease Interactions

The use of lurbinectedin can cause hepatotoxicity. Assess liver function tests, before administering lurbinectedin, periodically during treatment, and as clinically indicated. No dose adjustment is recommended for patients with mild hepatic impairment. Caution is recommended when using this agent in patients with moderate or severe hepatic impairment as the pharmacokinetics of lurbinectedin have not been studied in these patients. Withhold, reduce the dose, or permanently discontinue lurbinectedin based on severity.

The use of lurbinectedin can cause myelosuppression. Assess blood counts, including neutrophil count and platelet count before each therapy and administer lurbinectedin only to patients with baseline neutrophil count of at least 1,500 cells/mm3 and platelet count of at least 100,000/mm3. For neutrophil count less than 500 cells/mm3 or any value less than lower limit of normal, the use of G-CSF is recommended. Withhold, reduce the dose, or permanently discontinue lurbinectedin based on severity.
