8.1Pregnancy Pregnancy Surveillance Program
There is a Pregnancy Surveillance Program that monitors pregnancy outcomes in women exposed to VERQUVO during pregnancy. Health care providers should report any prenatal exposure to VERQUVO by calling 1-877-888-4231 or at https://pregnancyreporting.verquvo-us.com. Risk Summary Based on data from animal reproduction studies, VERQUVO may cause fetal harm when administered to a pregnant woman and is contraindicated during pregnancy [see Contraindications (4) ] .
There are no available data with VERQUVO use in pregnant women. In animal reproduction studies, oral administration of vericiguat to pregnant rabbits during organogenesis, at ≥4 times the human exposure (total AUC) with the maximum recommended human dose (MRHD) of 10 mg, resulted in malformations of the heart and major vessels, as well as increased number of abortions and resorptions ( see Animal Data ). In a pre/postnatal toxicity study, vericiguat administered orally to rats during gestation through lactation caused maternal toxicity, which resulted in decreased pup body weight gain (≥10 times the MRHD) and increased pup mortality (24 times the MRHD) during the preweaning period (see Animal Data ) .
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Data Animal Data In an embryo-fetal development study in rabbits, vericiguat was administered orally to pregnant rabbits during the period of organogenesis from gestation day (GD) 6 to 20 at doses of 0.75, 2.5 or 7.5 mg/kg/day.
An increased incidence of cardiac ventricular septal defect along with truncus arteriosus communis was observed at ≥2.5 mg/kg/day, which is ≥4 times the human exposure at the MRHD. Maternal toxicity (decreased food consumption and body weight loss), which may have resulted in late spontaneous abortions and resorptions was noted at ≥2.5 mg/kg/day (≥4 times the human exposure at the MRHD). There were no maternal toxicity or abortions/resorptions and no malformations of the heart and major vessels in rabbits at an exposure approximately equivalent to the human exposure at the MRHD.
In a prenatal developmental toxicity study in rats, vericiguat was administered orally to pregnant rats during the period of organogenesis from GD 6 to 17 at doses of 5, 15 or 50 mg/kg/day. No developmental toxicity was observed up to the highest dose (36 times the human exposure [total AUC] at the MRHD). Maternal toxicity (decreased body weight gain and food consumption) was observed at ≥15 mg/kg/day (≥10 times the human exposure at the MRHD).
There was no maternal toxicity at 5 mg/kg/day (4 times the human exposure at the MRHD). In a pre-postnatal development study in rats, vericiguat was administered orally at doses of 7.5, 15 or 30 mg/kg/day from GD 6 through lactation day 21. Maternal toxicity (decreases in food consumption and body weight gain) was observed at all dose levels ≥6 times the human exposure (total AUC) at the MRHD and resulted in decreased pup body weight gain at ≥15 mg/kg/day (≥10 times the human exposure at the MRHD) and pup mortality at 30 mg/kg/day (24 times the MRHD). [ 14 C]-vericiguat was administered orally to pregnant rats at a dose of 3 mg/kg.
Vericiguat-related material was transferred across the placenta, with fetal plasma concentrations of approximately 67% maternal concentrations on GD 19.
