WARNINGS AND PRECAUTIONS Neutropenic sepsis: Severe, and fatal, neutropenic sepsis may occur. Monitor neutrophil count during treatment. Withhold YONDELIS for neutrophil count < 1,500/mcL ( 2.4 , 5.1 ) Rhabdomyolysis: Rhabdomyolysis may occur. Monitor creatine phosphokinase (CPK) levels prior to each administration. Withhold YONDELIS for CPK more than 2.5 times the upper limit of normal. ( 2.4 , 5.2 ) Hepatotoxicity: Hepatotoxicity may occur. Monitor and delay and/or reduce dose if needed ( 5.3 ) Cardiomyopathy: Severe and fatal cardiomyopathy can occur. Patients with left ventricular ejection fraction (LVEF) < lower limit of normal, prior cumulative anthracycline dose of ≥300 mg/m 2 , age ≥65 years, or a history of cardiovascular disease may be at increased risk of developing new or worsening cardiac dysfunction. Discontinue YONDELIS in patients who develop decreased LVEF or cardiomyopathy ( 2.4 , 5.4 ) Capillary leak syndrome: Monitor and discontinue YONDELIS for capillary leak syndrome ( 5.5 ) Embryo-fetal toxicity: Can cause fetal harm. Advise of potential risk to a fetus and use effective contraception ( 5.7 , 8.1 , 8.3 ) 5.1 Neutropenic Sepsis Neutropenic sepsis, including fatal cases, can occur with YONDELIS. In Trial ET743-SAR-3007, the incidence of Grade 3 or 4 neutropenia, based on laboratory values, in patients receiving YONDELIS was 43% (161/378). The median time to the first occurrence of Grade 3 or 4 neutropenia was 16 days (range: 8 days to 9.7 months); the median time to complete resolution of neutropenia was 13 days (range: 3 days to 2.3 months). Febrile neutropenia (fever ≥38.5 °C with Grade 3 or 4 neutropenia) occurred in 18 patients (5%) treated with YONDELIS. Ten patients (2.6%) experienced neutropenic sepsis, 5 of whom had febrile neutropenia, which was fatal in 4 patients (1.1%). Assess neutrophil count prior to administration of each dose of YONDELIS and periodically throughout the treatment cycle. Withhold or reduce dose of YONDELIS based on severity of adverse reaction [see Dosage and Administration (2.4) ] . 5.2 Rhabdomyolysis YONDELIS can cause rhabdomyolysis and musculoskeletal toxicity. In Trial ET743-SAR-3007, rhabdomyolysis leading to death occurred in 3 (0.8%) of the 378 patients receiving YONDELIS. Elevations in creatine phosphokinase (CPK) occurred in 122 (32%) of the 378 patients receiving YONDELIS, including Grade 3 or 4 CPK elevation in 24 patients (6%), compared to 15 (9%) of the 172 patients receiving dacarbazine with any CPK elevation, including 1 patient (0.6%) with Grade 3 CPK elevation. Among the 24 patients receiving YONDELIS with Grade 3 or 4 CPK elevation, renal failure occurred in 11 patients (2.9%); rhabdomyolysis with the complication of renal failure occurred in 4 of these 11 patients (1.1%). The median time to first occurrence of Grade 3 or 4 CPK elevations was 2 months (range: 1 to 11.5 months). The median time to complete resolution was 14 days (range: 5 days to 1 month). Assess CPK levels prior to each administration of YONDELIS. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction [see Dosage and Administration (2.4) ] . 5.3 Hepatotoxicity Hepatotoxicity, including hepatic failure, can occur with YONDELIS. Patients with serum bilirubin levels above the upper limit of normal or AST or ALT levels >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). In Trial ET743-SAR-3007, the incidence of drug-induced liver injury (defined as concurrent elevation in ALT or AST of more than three times the upper limit of normal, alkaline phosphatase less than two times the upper limit of normal, and total bilirubin at least two times the upper limit of normal) was 1.3% (5/378) in patients receiving YONDELIS. ALT or AST elevation greater than eight times the upper limit of normal occurred in 18% (67/378) of patients receiving YONDELIS. Assess LFTs prior to each administration of YONDELIS and as clinically indicated based on underlying severity of pre-existing hepatic impairment. Manage elevated LFTs with treatment interruption, dose reduction, or permanent discontinuation based on severity and duration of LFT abnormality [see Dosage and Administration (2.4) and Use in Specific Populations (8.6) ]. 5.4 Cardiomyopathy Cardiomyopathy including cardiac failure, congestive heart failure, ejection fraction decreased, diastolic dysfunction, or right ventricular dysfunction can occur with YONDELIS. In Trial ET743-SAR-3007, a significant decrease in LVEF was defined as an absolute decrease of ≥15% or below the lower limit of normal with an absolute decrease of ≥5%. Patients with a history of New York Heart Association Class II to IV heart failure or abnormal left ventricular ejection fraction (LVEF) at baseline were ineligible. In Trial ET743-SAR-3007, cardiomyopathy occurred in 23 patients (6%) receiving YONDELIS and in four patients (2.3%) receiving dacarbazine. Grade 3 or 4 cardiomyopathy occurred in 15 patients (4%) receiving YONDELIS and 2 patients (1.2%) receiving dacarbazine; cardiomyopathy leading to death occurred in 1 patient (0.3%) receiving YONDELIS and in none of the patients receiving dacarbazine. The median time to development of Grade 3 or 4 cardiomyopathy in patients receiving YONDELIS was 5.3 months (range: 26 days to 15.3 months). Patients with LVEF < lower limit of normal, prior cumulative anthracycline dose of ≥300 mg/m 2 , age ≥65 years, or a history of cardiovascular disease may be at increased risk of cardiac dysfunction. Assess LVEF by echocardiogram (ECHO) or multigated acquisition (MUGA) scan before initiation of YONDELIS and at 2- to 3-month intervals thereafter until YONDELIS is discontinued. Discontinue treatment with YONDELIS based on severity of adverse reaction [see Dosage and Administration (2.4) ] . 5.5 Capillary Leak Syndrome Capillary leak syndrome (CLS) characterized by hypotension, edema, and hypoalbuminemia has been reported with YONDELIS, including serious CLS resulting in death. Monitor for signs and symptoms of CLS. Discontinue YONDELIS and promptly initiate standard management for patients with CLS, which may include a need for intensive care [see Adverse Reactions (6.2) ] . 5.6 Extravasation Resulting in Tissue Necrosis Extravasation of YONDELIS, resulting in tissue necrosis requiring debridement, can occur. Evidence of tissue necrosis can occur more than 1 week after the extravasation. There is no specific antidote for extravasation of YONDELIS. Administer YONDELIS through a central venous line [see Dosage and Administration (2.6) ] . 5.7 Embryo-Fetal Toxicity Based on its mechanism of action, YONDELIS can cause fetal harm when administered to a pregnant woman. Advise females of reproductive potential to use effective contraception during therapy and for at least 8 months after the last dose of YONDELIS. Advise males with female partners of reproductive potential to use effective contraception during therapy and for at least 5 months after the last dose of YONDELIS [see Use in Specific Populations (8.1 , 8.3) ] .

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

Mechanism of Action Trabectedin is an alkylating drug that binds guanine residues in the minor groove of DNA, forming adducts and resulting in a bending of the DNA helix towards the major groove. Adduct formation triggers a cascade of events that can affect the subsequent activity of DNA binding proteins, including some transcription factors, and DNA repair pathways, resulting in perturbation of the cell cycle and eventual cell death.
