FDA Black Box Warning
WARNING: EMBRYO-FETAL TOXICITY DAURISMO can cause embryo-fetal death or severe birth defects when administered to a pregnant woman. DAURISMO is embryotoxic, fetotoxic, and teratogenic in animals [see Warnings and Precautions (5.1) , Use in Specific Populations (8.1) ] . Conduct pregnancy testing in females of reproductive potential prior to initiation of DAURISMO treatment. Advise females of reproductive potential to use effective contraception during treatment with DAURISMO and for at least 30 days after the last dose [see Warnings and Precautions (5.1) , Use in Specific Populations (8.1 , 8.3) ] . Advise males of the potential risk of DAURISMO exposure through semen and to use condoms with a pregnant partner or a female partner of reproductive potential during treatment with DAURISMO and for at least 30 days after the last dose to avoid potential drug exposure [see Warnings and Precautions (5.1) , Use in Specific Populations (8.3) ] .

8.1 Pregnancy Risk Summary Based on its mechanism of action and findings in animal embryo-fetal developmental toxicity studies, DAURISMO can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) ] . There are no clinical data on the use of DAURISMO in pregnant women to inform of a drug-associated risk of major birth defects and miscarriage. DAURISMO is not recommended for use during pregnancy. Conduct pregnancy testing in female patients of reproductive potential prior to initiating treatment with DAURISMO. Report pregnancy exposures to Pfizer at 1-800-438-1985. In animal embryo-fetal developmental toxicity studies, repeat-dose oral administration of DAURISMO during organogenesis at maternal exposures that were less than the human exposure at the recommended dose resulted in embryotoxicity, fetotoxicity and teratogenicity in rats and rabbits (see Data ) . Advise pregnant women of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population are unknown. Adverse outcomes in pregnancy occur regardless of the health of the mother or the use of medications. 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 In embryo-fetal developmental toxicity studies, glasdegib was orally administered to pregnant rats and rabbits at doses up to 100 mg/kg/day during the period of organogenesis. Glasdegib resulted in embryo-fetal lethality (e.g., increased postimplantation loss and decreased numbers of live fetuses) in rats and rabbits at 50 mg/kg/day and 5 mg/kg/day, respectively, at maternal exposures approximately 4-times and 3-times the human exposure at the recommended dose [based on C max (rat) and AUC (rabbit)]. Doses of ≥10 mg/kg in rat [approximately 0.6-times the human exposure (C max ) at the recommended dose] and ≥5 mg/kg in rabbi
