5 Warnings and Precautions

5.7 Embryo-Fetal Toxicity

Additions and/or revisions underlined:

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)].


8 Use in Specific Populations

8.2 Lactation

Additions and/or revisions underlined:

Risk Summary

There are no data on the presence of trabectedin in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions from YONDELIS in a breastfed child, advise a nursing woman to discontinue nursing during treatment with and for 3 months after the last dose of YONDELIS.

8.3 Females and Males of Reproductive Potential

Additions and/or revisions underlined:

. . .

Contraception

Females

Advise female patients of reproductive potential to use effective contraception during and for 8 months after the last dose of YONDELIS [see Use in Specific Populations (8.1)].

Males

YONDELIS may damage spermatozoa, resulting in possible genetic and fetal abnormalities. Advise males with a female sexual partner of reproductive potential to use effective contraception during and for 5 months after the last dose of YONDELIS [see Nonclinical Toxicology (13.1)].

5 Warnings and Precautions

5.1 Neutropenic Sepsis

(Additions and/or revisions are underlined)

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.

5.2 Rhabdomyolysis

(Additions and/or revisions are underlined)

 

Assess CPK levels prior to each administration of YONDELIS. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction.

5.4   Cardiomyopathy

(Additions and/or revisions are underlined)

 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 greater than or equal to 15% or below the lower limit of normal with an absolute decrease of greater than or equal to 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/m2, 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.

8.3 Females and Males of Reproductive Potential

 (addition underlined)

Pregnancy Testing

Verify the pregnancy status of females of reproductive potential prior to initiating YONDELIS

8.4 Pediatric Use

(additions underlined)

Safety and effectiveness in pediatric patients have not been established.

Safety (n=61) and efficacy (n=58) were assessed across five open-label studies (NCT00006463, NCT01453283, NCT00005625, NCT00070109, and ET-B-023-00) in pediatric patients (aged 2 to <17 years) with pediatric histotypes of sarcoma (predominantly rhabdomyosarcoma, osteosarcoma, Ewing sarcoma, and non-rhabdomyosarcoma soft tissue sarcoma). No new safety signals were observed in pediatric patients across these studies.

Pharmacokinetic parameters in 17 pediatric patients (aged 3 to 17 years) were within the range of values previously observed in adults given the same dose per body surface area.

5 Warnings and Precautions

5.5 Capillary Leak Syndrome

(Newly added subsection)

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.

6 Adverse Reactions

(Additions and/or revisions are underlined)

The following adverse reactions are discussed in more detail in other sections of the labeling:

•  Capillary Leak Syndrome

6.2 Postmarketing Experience

(Newly added subsection)

The following adverse reactions have been identified during post-approval use of YONDELIS. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Vascular disorders: capillary leak syndrome .

17 PCI/PI/MG (Patient Counseling Information/Patient Information/Medication Guide)

17 PATIENT COUNSELING INFORMATION

(Additions and/or revisions are underlined)

Advise the patient to read the FDA-approved patient labeling (Patient Information).

Capillary leak syndrome: Advise patients to report symptoms such as edema with or without hypotension.

PATIENT INFORMATION YONDELIS® (yon-DEL-ess) (trabectedin) for injection

(Additions and/or revisions are underlined)

What are the possible side effects of YONDELIS?

•         Heart muscle problems, including heart failure. Your healthcare provider will do a test to check your heart function before you start YONDELIS, and during treatment. If you develop heart muscle problems or heart failure during treatment with YONDELIS, your healthcare provider may stop your treatment.

•         Capillary leak syndrome. YONDELIS can cause fluid to leak from the blood vessels into the body’s tissues. This condition is called “Capillary Leak Syndrome” (CLS). CLS can cause you to have symptoms that may lead to death. Tell your healthcare provider right away if you develop swelling, dizziness or lightheadedness with or without a sudden drop in blood pressure.

8 Use in Specific Populations

Hepatic Impairment

  • The mean trabectedin exposure was (97%) higher in patients with moderate (bilirubin levels 1.5 to 3.0 times the upper limit of normal, and AST and ALT less than 8 times the upper limit of normal) hepatic impairment compared to patients with normal (total bilirubin ? the upper limit of normal, and AST and ALT = the upper limit of normal) liver function. Reduce YONDELIS dose in patients with moderate hepatic impairment.
  • Do not administer YONDELIS to patients with severe hepatic impairment (bilirubin levels above 3 times to 10 times the upper limit of normal, and any AST and ALT).
