Pregnancy
Pregnancy
Based on its mechanism of action and findings in animals, can cause fetal harm when administered to pregnant women
Administration to pregnant rats during the period of organogenesis resulted in dose-related skeletal anomalies at doses as low as 12.5 mg/kg/day (~0.7 times the human exposure by AUC at 180 mg once daily), as well as increased postimplantation loss, malformations, and decreased fetal body weight at doses of 25 mg/kg/day (~1.26 times the human exposure at 180 mg once daily) or greater
Infertility: Based on findings in male reproductive organs in animals, may cause reduced fertility in males
Contraception
- Females: Advise females of reproductive potential to use effective nonhormonal contraception during treatment and for at least 4 months after the final dose
- Counsel patients to use a nonhormonal method of contraception since brigatinib can render some hormonal contraceptives ineffective
- Males: Because of the potential for genotoxicity, advise males with female partners of reproductive potential to use effective contraception during treatment and for at least 3 months after the final dose
Lactation
Unknown if distributed in human breast milk
Because of the potential for adverse reactions in breastfed infants, advise lactating women not to breastfeed during treatment and for 1 week following the final dose
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
