Enlicitide decanoate

8.1 Pregnancy Risk Summary Discontinue LIPFENDRA when pregnancy is recognized unless the benefits of therapy outweigh the potential risks to the fetus. Alternatively, consider the ongoing therapeutic needs of the individual patient. Enlicitide increases LDL-C uptake and lowers LDL-C levels in the circulation, thus decreasing cholesterol and possibly other biologically active substances derived from cholesterol; therefore, LIPFENDRA may cause fetal harm when administered to pregnant patients based on the mechanism of action [see Clinical Pharmacology (12.1) ] .

There are insufficient data on the use of LIPFENDRA in pregnant patients to evaluate for a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Consider the benefits and risks of LIPFENDRA when prescribing LIPFENDRA to pregnant women. In animal reproduction studies, no adverse embryofetal developmental effects were observed in pregnant rats and rabbits administered enlicitide subcutaneously during organogenesis (up to 58- and 51-fold, respectively, the human exposure at the recommended human dose (RHD), based on AUC) (see Data ) . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.

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. Data Animal Data In the embryofetal developmental rat toxicity study, pregnant rats were administered enlicitide subcutaneously at 0.5, 3, or 10 mg/kg/day during the period of organogenesis (Gestational Days (GD) 6 through 17). No adverse embryofetal or maternal effects were observed up to 10 mg/kg/day (58-fold the human exposure at the RHD, based on AUC).

In the embryofetal developmental rabbit toxicity study, pregnant rabbits were administered enlicitide subcutaneously at 0.2, 0.5, or 3 mg/kg/day during the period of organogenesis (GD7 through 19). No adverse embryofetal or maternal effects were observed up to 3 mg/kg/day (51-fold the human exposure at the RHD, based on AUC). In the rat pre- and postnatal developmental toxicity study, enlicitide was administered subcutaneously at 0.5, 3, or 10 mg/kg/day daily from GD 6 through lactation day (LD) 20. No adverse developmental or maternal effects were observed up to 10 mg/kg/day (58-fold the human exposure at the RHD, based on AUC).

Enlicitide crosses the placenta and was detected in rat fetal plasma at concentrations that were 3 to 5% of mean maternal plasma concentrations.
