Interactions
7 DRUG INTERACTIONS CYP3A inhibitors: Avoid concomitant strong CYP3A inhibitors ( 7.1 ) CYP3A inducers: Avoid concomitant strong CYP3A inducers ( 7.2 ) 7.1 Effect of Cytochrome CYP3A Inhibitors Coadministration of YONDELIS with ketoconazole, a strong CYP3A inhibitor, increased systemic exposure of trabectedin by 66%. Avoid using strong CYP3A inhibitors (e.g., oral ketoconazole, itraconazole, posaconazole, voriconazole, clarithromycin, telithromycin, indinavir, lopinavir, ritonavir, boceprevir, nelfinavir, saquinavir, telaprevir, nefazodone, conivaptan) in patients taking YONDELIS.
Warnings
5 WARNINGS AND PRECAUTIONS Neutropenic sepsis: Severe, and fatal, neutropenic sepsis may occur. Monitor neutrophil count during treatment. Withhold YONDELIS for neutrophil count 2.5 × upper limit of normal were not enrolled in Trial ET743-SAR-3007. In Trial ET743-SAR-3007, the incidence of Grade 3–4 elevated liver function tests (LFTs; defined as elevations in ALT, AST, total bilirubin, or alkaline phosphatase) was 35% (134/378) in patients receiving YONDELIS. The median time to development of Grade 3–4 elevation in ALT or AST was 29 days (range: 3 days to 11.5 months). Of the 134 patients with Grade 3–4 elevations in LFTs, 114 (85%) experienced complete resolution with the median time to complete resolution of 13 days (range: 4 days to 4.4 months). 4 CONTRAINDICATIONS YONDELIS is contraindicated in patients with known severe hypersensitivity, including anaphylaxis, to trabectedin. Known hypersensitivity to trabectedin ( 4 )
