8.1Pregnancy Risk Summary
Available data with JESDUVROQ use in pregnant women are insufficient to establish a drug associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. There are risks to the mother and the fetus associated with CKD ( see Clinical Considerations ) . Daprodustat administered orally to pregnant rats and rabbits during the period of organogenesis was associated with adverse fetal outcomes, including embryonic and fetal loss and reduced fetal weight, at doses that caused maternal toxicity and polycythemia ( see Data ).
Advise pregnant women of the potential risk to the fetus. The 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% to 4% and 15% to 20%, respectively.
Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk: CKD in pregnancy increases the risk for maternal hypertension, preeclampsia, miscarriage, stillbirth, preterm delivery, low birth weight infants, and polyhydramnios. Data Animal Data : Daprodustat was orally administered to pregnant rats at 0.5, 7, or 60 mg/kg/day from gestation day 6 to gestation day 17 during the period of organogenesis. No adverse effects were observed at doses less than or equal to 7 mg/kg/day (3 times the maximum recommended human dose [MRHD] based on body surface area).
Daprodustat administration resulted in post-implantation loss, increased embryofetal death, and reduction in skeletal ossification in rats at a dose of 60 mg/kg/day (24 times the MRHD based on body surface area), which was associated with maternal toxicity (reduced body weight gain or weight loss). Maternal toxicity occurred at doses associated with polycythemia. Daprodustat was orally administered to pregnant rabbits at doses of 4, 30, or 60 mg/kg/day from gestation day 7 until gestation day 19 during the period of organogenesis.
No adverse effects were observed at doses less than or equal to 30 mg/kg/day (24 times the MRHD based on body surface area). Daprodustat administration was associated with a low incidence of abortions and fetal skeletal malformations (irregularly shaped anterior fontanelle, manubrium, fused sternal centra, and microphthalmia) at a dose of 60 mg/kg/day (49 times the MRHD based on body surface area) in the presence of maternal toxicity (reduced body weight gain or weight loss) and polycythemia.
In a pre- and postnatal development study, pregnant rats were dosed orally with daprodustat from implantation until weaning (gestation day 6 to lactation day 21) at 0.8, 7, or 40 mg/kg/day concomitantly with 3 major human metabolites of daprodustat. No adverse effects were observed at doses less than or equal to 7 mg/kg/day (3 times the MRHD based on body surface area). Maternal toxicity (in the presence of polycythemia) was noted at 40 mg/kg/day (16 times the MRHD based on body surface area), which was associated with increased pup deaths and decreased pup weights.
