8 Use in Specific Populations

8.1 Pregnancy

(PLLR conversion)

Risk Summary

Based on findings from animal studies and its mechanism of action, COSMEGEN can cause fetal harm when administered to a pregnant woman.In animal reproduction studies, administration of dactinomycin to pregnant animals during the period of organogenesis was teratogenic, resulting in malformations at doses lower than the recommended human dose (see Data). Advise pregnant women of the potential risk to a fetus.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Data

Animal Data

Dactinomycin was teratogenic in animals. Administration of dactinomycin to pregnant rats, rabbits, and hamsters during the period of organogenesis, increased the incidence of fetal malformations and caused embryotoxicity at doses (based on body surface area) as low as 0.2 times the clinical dose of 1250 mcg/m2.

8.2 Lactation

(PLLR conversion)

Risk Summary

There are no data on the presence of dactinomycin or its metabolites in human milk or their effects on the breastfed infant or on milk production. Because of the potential for serious adverse reactions in breastfed infants from COSMEGEN, advise women not to breastfeed during treatment with COSMEGEN and, based on limited published data regarding the dactinomycin half-life, for 14 days after the final dose.

8.3 Females and Males of Reproductive Potential

(PLLR conversion)

Pregnancy Testing

Verify the pregnancy status of females of reproductive potential prior to initiating COSMEGEN.

Contraception

COSMEGEN can cause fetal harm when administered to a pregnant woman.

Females

Advise females of reproductive potential to use effective contraception during treatment with COSMEGEN and for at least 6 months after the final dose.

Males

Because of the potential for genotoxicity, advise males with female partners of reproductive potential to use effective contraception during treatment with COSMEGEN and for 3 months after the final dose.

8.4 Pediatric Use

(additions underlined)

The safety and effectiveness of dactinomycin have been established in pediatric patients with Wilms tumor, rhabdomyosarcoma, Ewing sarcoma, and metastatic nonseminomatous testicular cancer.

The safety and effectiveness of dactinomycin have been established in post-menarchal pediatric patients with gestational trophoblastic neoplasia.

The safety and effectiveness of COSMEGEN have not been established in pediatric patients undergoing regional perfusion for locally recurrent or locoregional solid malignancies.

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

PATIENT COUNSELING INFORMATION

(PLR conversion; new subsection added)

Secondary Malignancy or Leukemia

Advise patients of the increased risk of secondary malignancies.

Veno-occlusive Disease

Advise patients about the symptoms of VOD and to seek medical attention if they develop new onset jaundice, abdominal distention, or right upper quadrant pain.

Myelosuppression

Advise patients to contact their healthcare provider for any signs or symptoms of myelosuppression or infection.

Severe Mucocutaneous Reactions

Advise patients of the risk of severe mucocutaneous reactions and to contact their health care provided for new skin lesions, mouth sores or oropharyngeal lesions.

Renal Toxicity or Hepatotoxicity

Advise patients of the need for periodic laboratory testing to monitor for renal toxicity and hepatotoxicity.

Potentiation of Radiation Toxicity and Radiation Recall

Advise patients of the risk of increased radiation-induced gastrointestinal, myelosuppression and skin toxicity.

Embryo-Fetal Toxicity

Advise females of reproductive potential of the potential risk to a fetus. Advise females to inform their healthcare provider of a known or suspected pregnancy.

Advise females of reproductive potential to use effective contraception during treatment with COSMEGEN and for 6 months after final dose.

Advise male patients with female partners of reproductive potential to use effective contraception during treatment with COSMEGEN and for 3 months after final dose.

Lactation

Advise females not to breastfeed during treatment with COSMEGEN and for 14 days after the final dose.
