Side Effects (Adverse Reactions)

6 ADVERSE REACTIONS The following adverse reactions are discussed in more detail in other sections of the labeling: Anaphylaxis [see Contraindications (4) ] Neutropenic Sepsis [see Warnings and Precautions (5.1) ] Rhabdomyolysis [see Warnings and Precautions (5.2) ] Hepatotoxicity [see Warnings and Precautions (5.3) ] Cardiomyopathy [see Warnings and Precautions (5.4) ] Capillary Leak Syndrome [see Warnings and Precautions (5.5) ] Extravasation Resulting in Tissue Necrosis [see Warnings and Precautions (5.6) ] The most common (≥20%) adverse reactions are nausea, fatigue, vomiting, constipation, decreased appetite, diarrhea, peripheral edema, dyspnea, and headache. The most common (≥5%) grades 3–4 laboratory abnormalities are: neutropenia, increased ALT, thrombocytopenia, anemia, increased AST, and increased creatine phosphokinase. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Janssen Products, LP at 1-800-526-7736 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data described below reflect exposure to YONDELIS in 755 patients with soft tissue sarcoma including 197 (26%) patients exposed to YONDELIS for greater than or equal to 6 months and 57 (8%) patients exposed to YONDELIS for greater than or equal to 1 year. The safety of YONDELIS was evaluated in six open-label, single-arm trials, in which 377 patients received YONDELIS and one open-label, randomized, active-controlled clinical trial in which 378 patients received YONDELIS (Trial ET743-SAR-3007). All patients received YONDELIS at the recommended dosing regimen of 1.5 mg/m 2 administered as an intravenous infusion over 24 hours once every 3 weeks (q3wk, 24-h). The median age was 54 years (range: 18 to 81 years), 63% were female, and all patients had metastatic soft tissue sarcoma. Tables 3 and 4 present selected adverse reactions and laboratory abnormalities, respectively, observed in Trial ET743-SAR-3007, an open-label, randomized (2:1), active-controlled trial in which 550 patients with previously treated leiomyosarcoma or liposarcoma (dedifferentiated, myxoid round cell, or pleomorphic) received YONDELIS 1.5 mg/m 2 intravenous infusion over 24 hours once every 3 weeks (n=378) or dacarbazine 1000 mg/m 2 intravenous infusion over 20 to 120 minutes once every 3 weeks (n=172) [see Clinical Studies (14) ] . All patients treated with YONDELIS were required to receive dexamethasone 20 mg intravenous injection 30 minutes prior to start of the YONDELIS infusion. In Trial ET743-SAR-3007, patients had been previously treated with an anthracycline- and ifosfamide-containing regimen or with an anthracycline-containing regimen and one additional cytotoxic chemotherapy regimen. The trial excluded patients with known central nervous system metastasis, elevated serum bilirubin or significant chronic liver disease, such as cirrhosis or active hepatitis, and history of myocardial infarction within 6 months, history of New York Heart Association Class II to IV heart failure, or abnormal left ventricular ejection fraction at baseline. The median age of patients in Trial ET743-SAR-3007 was 57 years (range: 17 to 81 years), with 69% female, 77% White, 12% Black or African American, 4% Asian, and <1% American Indian or Alaska Native. The median duration of exposure to trabectedin was 13 weeks (range: 1 to 127 weeks) with 30% of patients exposed to YONDELIS for greater than 6 months and 7% of patients exposed to YONDELIS for greater than 1 year. In Trial ET743-SAR-3007, adverse reactions resulting in permanent discontinuation of YONDELIS occurred in 26% (98/378) of patients; the most common were increased liver tests (defined as ALT, AST, alkaline phosphatase, bilirubin) (5.6%),...

Drug 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. If a strong CYP3A inhibitor for short-term use (i.e., less than 14 days) must be used, administer the strong CYP3A inhibitor 1 week after the YONDELIS infusion, and discontinue it the day prior to the next YONDELIS infusion [see Clinical Pharmacology (12.3) ] . 7.2 Effect of Cytochrome CYP3A Inducers Coadministration of YONDELIS with rifampin, a strong CYP3A inducer, decreased systemic exposure of trabectedin by 31%. Avoid using strong CYP3A inducers (e.g., rifampin, phenobarbital, St. John's wort) in patients taking YONDELIS [see Clinical Pharmacology (12.3) ] . Drug Interactions Effect of Strong CYP3A Inhibitors on Trabectedin Coadministration of multiple doses of ketoconazole (200 mg twice daily for 7.5 days) with a single dose of YONDELIS (0.58 mg/m 2 ) on day 1 increased trabectedin dose-normalized AUC by 66% and C max by 22% compared to a single YONDELIS dose (1.3 mg/m 2 ) given alone. Effect of Strong CYP3A Inducers on Trabectedin Coadministration of multiple doses of rifampin (600 mg daily for 6 days) with a single YONDELIS dose (1.3 mg/m 2 ) on day 6 decreased trabectedin AUC by 31% and C max by 21% compared to a single YONDELIS dose (1.3 mg/m 2 ) given alone. Effect of Trabectedin on CYP Enzymes In vitro , trabectedin has limited inhibition or induction potential of major CYP enzymes (CYP1A2, 2A6, 2B6, 2C9, 2C19, 2D6, 2E1, and 3A4).

Contraindications

4 CONTRAINDICATIONS YONDELIS is contraindicated in patients with known severe hypersensitivity, including anaphylaxis, to trabectedin. Known hypersensitivity to trabectedin ( 4 )

Pregnancy and Breastfeeding

8.1 Pregnancy Risk Summary Based on its mechanism of action, trabectedin can cause fetal harm when administered during pregnancy [see Clinical Pharmacology (12.1) ] . There are no available data with the use of YONDELIS during pregnancy. Animal reproductive and developmental studies at relevant doses have not been conducted with trabectedin; however, placental transfer of trabectedin was demonstrated in pregnant rats. Advise pregnant woman of the potential risk to a fetus. The background risk of major birth defects and miscarriage for the indicated population are unknown; however, the background risk in the U.S. general population of major birth defects is 2 to 4% and of miscarriage is 15 to 20% of clinically recognized pregnancies.

Overdosage

10 OVERDOSAGE There is no specific antidote for YONDELIS. Hemodialysis is not expected to enhance the elimination of YONDELIS because trabectedin is highly bound to plasma proteins (97%) and not significantly renally excreted.
