Risk Summary: Based on its mechanism of action and findings from animal studies, this drug can cause embryofetal harm when administered to a pregnant woman.

Comments:
-This drug can harm a developing fetus.
-Advise females of reproductive potential and males with female partners of reproductive potential to use effective methods of contraception during treatment and for at least 1 month after.

-If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential harm to the fetus.

Animal studies have revealed evidence of embryotoxicity and teratogenicity at doses of 0.1, 0.2, or 0.5 mg/kg/day. Embryofetal adverse effects were observed in pregnant rats after systemic exposures greater or equal to 0.2% of the human exposure at the recommended dose of 14 mg/m2/week. Drug-related fetal effects included folded retina, rotated limbs, and incomplete sternal ossification. Substantial resorption or postimplantation loss was observed at the high-dose of 0.5 mg/kg/day, a maternally toxic dose. There are no controlled data in human pregnancy.

AU TGA pregnancy category D: Drugs which have caused, are suspected to have caused or may be expected to cause, an increased incidence of human fetal malformations or irreversible damage. These drugs may also have adverse pharmacological effects. Accompanying texts should be consulted for further details.

US FDA pregnancy category Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy. Pregnancy categories A, B, C, D and X are being phased out.
