  • 5 WARNINGS AND PRECAUTIONS

    5.1 Secondary Malignancy or Leukemia

    The risk of developing secondary malignancies, including leukemia, is increased following treatment with Dactinomycin.

    5.2 Veno-occlusive Disease

    Severe and fatal hepatic veno-occlusive disease (VOD) can occur with Dactinomycin. Risk factors for the development of VOD include age younger than 4 years or concomitant radiotherapy. After treatment with Dactinomycin, monitor frequently for signs and symptoms of VOD; these include elevations in AST, ALT, total bilirubin, hepatomegaly, weight gain, or ascites. If patients develop VOD, considering delaying next dose of Dactinomycin. Resume, reduce dose or permanently discontinue based on severity of reaction and disease being treated.

    5.3 Extravasation

    Extravasation of Dactinomycin can result in severe local tissue injury manifesting as blistering, ulcerations and persistent pain requiring wide excision surgery followed by split-thickness skin grafting. If any signs or symptoms of extravasation occur, immediately interrupt the injection or infusion. Apply ice to the site intermittently for 15 minutes, 4 times a day for 3 days [see Dosage and Administration ( 2.7)] . Observe closely and consult plastic surgery if necessary based on severity of reaction.

    5.4 Myelosuppression

    Severe and fatal myelosuppression, which may include neutropenia, thrombocytopenia and anemia, can occur with Dactinomycin. The nadir in neutrophil counts generally occurs 14 to 21 days after administration. Obtain complete blood counts prior to each treatment cycle. Delay next dose of Dactinomycin if severe myelosuppression has not improved. Consider dose reduction for patients with prolonged myelosuppression based on severity of reaction and disease being treated.

    5.5 Immunizations

    The safety with live viral vaccines following Dactinomycin has not been studied and vaccination with live virus vaccines is not recommended before or during treatment.

    5.6 Severe Mucocutaneous Reactions

    Severe mucocutaneous reactions, such as Steven-Johnson syndrome and Toxic Epidermal Necrolysis (TEN), can occur with Dactinomycin. Permanently discontinue Dactinomycin in patients who experience a severe mucocutaneous reaction.

    5.7 Renal Toxicity

    Abnormalities of renal function can occur with Dactinomycin. Monitor creatinine and electrolytes frequently during Dactinomycin therapy.

    5.8 Hepatotoxicity

    Hepatotoxicity can occur with Dactinomycin. Monitor AST, ALT, alkaline phosphatase, and bilirubin prior to and during Dactinomycin therapy.

    5.9 Potentiation of Radiation Toxicity and Radiation Recall

    Dactinomycin can increase radiation-induced gastrointestinal toxicity, myelosuppression, or erythema and vesiculation of the skin or buccal and pharyngeal mucosa. Reduce the dose of Dactinomycin by 50% during concomitant radiation.

    Radiation recall, affecting previously treated radiation fields, can occur in patients who receive Dactinomycin after prior radiation therapy. Although the risk can occur with distant radiation exposure, the risk appears highest when Dactinomycin is administered within two months of prior radiation.

    5.10 Embryo-Fetal Toxicity

    Based on findings from animal studies and its mechanism of action, Dactinomycin 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.

    Advise pregnant women of the potential risk to the fetus. Advise females of reproductive potential to use effective contraception during treatment with Dactinomycin and for at least 6 months after the final dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with Dactinomycin and for 3 months after the final dose [see Use in Specific Populations ( 8.1, 8.3)].

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    Based on findings from animal studies and its mechanism of action, Dactinomycin can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology ( 12.1)] . 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 [see Use in Special Populations ( 8.3)] .

    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/m 2.

    8.2 Lactation

    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 Dactinomycin, advise women not to breastfeed during treatment with Dactinomycin 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

    Pregnancy Testing

    Verify the pregnancy status of females of reproductive potential prior to initiating Dactinomycin [see Use in Specific Population ( 8.1)].

    Contraception

    Dactinomycin can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations ( 8.1)].

    Females

    Advise females of reproductive potential to use effective contraception during treatment with Dactinomycin 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 Dactinomycin and for 3 months after the final dose [see Nonclinical Toxicology ( 13.1)].

    8.4 Pediatric Use

    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 Dactinomycin have not been established in pediatric patients undergoing regional perfusion for locally recurrent or locoregional solid malignancies.

    8.5 Geriatric Use

    Clinical studies of Dactinomycin did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Dactinomycin is a cytotoxic actinomycin that binds DNA and inhibits RNA synthesis. The cytotoxic activity of dactinomycin has been demonstrated in animal models of different human cancers.

    12.2 Pharmacodynamics

    Dactinomycin exposure-response relationships and the time course of pharmacodynamics response are unknown.

    12.3 Pharmacokinetics

    The distribution and excretion of radiolabeled dactinomycin ( 3H actinomycin D) were assessed in three adult patients with malignant melanoma.

    Distribution

    3H actinomycin D is concentrated in nucleated cells and does not penetrate the blood-brain barrier.

    Elimination

    Excretion

    Following administration of radiolabeled dactinomycin, approximately 30% was recovered in urine and feces in one week.

    Specific Populations

    Pediatric Patients

    Published studies and population analyses in patients ≤ 21 years of age with cancer report a trend of increasing systemic dactinomycin clearance with increasing body weight.

    Drug Interaction Studies

    Published in vitro studies report that dactinomycin may be a substrate of the P-glycoprotein and OATP1B3 transporter systems.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Dactinomycin is a carcinogen in animals. Local sarcomas were produced in mice and rats after repeated subcutaneous or intraperitoneal injections. Mesenchymal tumors occurred in male rats given intraperitoneal injections of 50 mcg/kg, 2 to 5 times per week, for 18 weeks, at doses (based on body surface area) 0.5 times the clinical dose of 1250 mcg/m 2.

    Dactinomycin was mutagenic in several in vitro and in vivo test systems including human fibroblasts and leukocytes, and HeLa cells. DNA damage and cytogenetic effects have been demonstrated in the mouse and the rat.
