Opicapone Interactions

Pregnancy & Breastfeeding

8.1 Pregnancy Risk Summary There are no adequate data on the developmental risk associated with use of ONGENTYS in pregnant women. In animal studies, oral administration of opicapone during pregnancy resulted in adverse effects on embryofetal development (increased incidence of fetal abnormalities) at clinically relevant plasma exposures in one of two species tested. In addition, opicapone is always given concomitantly with levodopa/carbidopa, which is known to cause developmental toxicity in rabbits ( s ee Data ). The background risk of major birth defects and miscarriage in the U.S. general population is 2-4% and 15-20% of clinically recognized pregnancies, respectively. The background risk for major birth defects and miscarriage in patients with Parkinson’s disease is unknown. Data Animal Data Oral administration of opicapone (0, 150, 375, or 1000 mg/kg/day) to pregnant rats throughout gestation resulted in no adverse effects on embryofetal development. Plasma exposure (AUC) at the highest dose tested (1000 mg/kg/day) was approximately 40 times that in humans at the recommended human dose (50 mg/day). In pregnant rabbits, oral administration of opicapone (0, 100, 175, or 225 mg/kg/day) during the period of organogenesis resulted in increased incidence of structural abnormalities at all doses tested; maternal toxicity was observed at all but the lowest dose tested. A no-effect dose for adverse effects on embryofetal development was not identified. Plasma exposure (AUC) at the low-effect dose (100 mg/kg/day) was less than that in humans at the RHD. Oral administration of opicapone (0, 150, 375, or 1000 mg/kg/day) throughout gestation and lactation resulted in no adverse effects on pre- and postnatal development; however, effects on neurobehavioral development in the offspring were not rigorously assessed. Plasma exposure (AUC) at the highest dose tested (1000 mg/kg/day) was approximately 40 times that in humans at the RHD. Opicapone is always given concomitantly wi
