Pregnancy & Breastfeeding
8.1 Pregnancy Risk Summary There are no adequate data on the developmental risk associated with the use of NEUPRO in pregnant women. In animal studies, rotigotine was shown to have adverse effects on embryofetal development when administered during pregnancy at doses similar to or lower than those used clinically [ see Data ]. In the U.S. general population, the estimated background risk of major birth defects and of miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. The background risk of major birth defects and miscarriage in the indicated population is unknown. Data Animal Data Rotigotine administered subcutaneously (0, 10, 30, or 90 mg/kg/day) to pregnant mice during organogenesis (gestation days 6 through 15) resulted in increased incidences of delayed skeletal ossification and decreased fetal body weights at the two highest doses and an increase in embryofetal death at the high dose. The no-effect dose for embryofetal developmental toxicity in mice is approximately 6 times the maximum recommended human dose (MRHD) for Parkinson's disease (8 mg/24 hours) on a body surface area (mg/m 2 ) basis. Rotigotine administered subcutaneously (0, 0.5, 1.5, or 5 mg/kg/day) to pregnant rats during organogenesis (gestation days 6 through 17) resulted in increased embryofetal death at all doses. The lowest effect dose is less than the MRHD on a mg/m 2 basis. This effect in rats is thought to be due to the prolactin-lowering effect of rotigotine. When rotigotine was administered subcutaneously (0, 5, 10, or 30 mg/kg/day) to pregnant rabbits during organogenesis (gestation days 7 through 19), an increase in embryofetal death occurred at the two highest doses tested. The no-effect dose is 12 times the MRHD on a mg/m 2 basis. In a study in which rotigotine was administered subcutaneously (0, 0.1, 0.3, or 1 mg/kg/day) to rats throughout pregnancy and lactation (gestation day 6 through postnatal day 21), impaired growth and development during
