Pregnancy & Breastfeeding
8.1 Pregnancy Risk Summary Based on animal data showing renal effects, INPEFA is not recommended during the second and third trimesters of pregnancy. Available data with INPEFA in pregnant women are insufficient to evaluate for a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. There are risks to the mother and fetus associated with untreated heart failure in pregnancy [see Clinical Considerations ] . In rats, renal changes were observed when sotagliflozin was administered during a period of renal development corresponding to the late second and third trimesters of human pregnancy. Exposure approximately 5 times the clinical exposure at the maximum recommended human dose (MRHD) of 400 mg once daily caused increased kidney weights and renal pelvis and tubule dilatations that were partially reversible [see 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% to 4% and 15% to 20%, respectively. Clinical Considerations Disease-associated Maternal and/or Embryo-fetal Risk Pregnant women with congestive heart failure are at increased risk for preterm birth. Clinical classification of heart disease may worsen with pregnancy and lead to maternal death. Data Animal Data In embryo-fetal development studies in rats and rabbits, sotagliflozin was administered for intervals coinciding with the first trimester period of organogenesis in humans. Sotagliflozin was not teratogenic when administered at doses up to 100 mg/kg/day in pregnant rats during embryonic organogenesis (40 times the human exposure at the MRHD). Higher exposures (350 mg/kg or 161 times the human exposure at the MRHD) resulted in embryo-lethality, effects on fetal gro
