LIPFENDRA

LIPFENDRA ® is indicated as an adjunct to diet and exercise to reduce low-density lipoprotein cholesterol (LDL-C) in adults with hypercholesterolemia, including heterozygous familial hypercholesterolemia (HeFH). Cardiovascular outcomes trials have demonstrated that reducing LDL-C lowers the risk for major adverse cardiovascular events (MACE) in adults at increased risk when treated with statins or monoclonal antibody proprotein convertase subtilisin kexin type 9 (PCSK9) inhibitors as an add-on to statin therapy. LIPFENDRA is a proprotein convertase subtilisin kexin type 9 (PCSK9) inhibitor indicated as an adjunct to diet and exercise to reduce low-density lipoprotein cholesterol (LDL-C) in adults with hypercholesterolemia, including heterozygous familial hypercholesterolemia (HeFH). Cardiovascular outcomes trials have demonstrated that reducing LDL-C lowers the risk for major adverse cardiovascular events (MACE) in adults at increased risk when treated with statins or monoclonal antibody PCSK9 inhibitors as an add-on to statin therapy.

Advise the patient to read the FDA-approved patient labeling ( Patient Information ). Dosage and Administration Instruct patients to take their dose of LIPFENDRA on an empty stomach in the morning with water, black coffee, or plain tea and to wait at least 30 minutes before their next food or beverage (other than water, black coffee, or plain tea). Each tablet should be swallowed whole [see Dosage and Administration (2.2) ] . LIPFENDRA can be taken with other medications [see Clinical Pharmacology (12.3) ] . Missed Doses Advise the patient that if a dose is missed, they should take the missed dose as soon as possible, at least 30 minutes before the next food or drink (other than water, black coffee, or plain tea). They should not take 2 doses on the same day [see Dosage and Administration (2.2) ] .

Carcinogenesis In a 26-week study in RasH2Tg mice, enlicitide was administered daily both by subcutaneous and oral routes at subcutaneous/oral dosages of 2.5/1, 10/2 or 30/4 mg/kg/day. Enlicitide was not carcinogenic in rasH2 transgenic mice up to the highest dose tested, corresponding to 59-fold the human exposure at the RHD, based on AUC. Based on a comprehensive assessment of the available toxicology data and the PCSK9-specific target, enlicitide is not expected to be carcinogenic in humans. Mutagenesis Enlicitide was not mutagenic or genotoxic in a standard battery of genotoxicity tests that included a microbial mutagenicity assay, an in vitro chromosome aberration assay and an in vivo micronucleus assay in rats. Impairment of Fertility In fertility and early embryonic-development studies, male or female rats were administered enlicitide subcutaneously at doses of 1, 5, or 10 mg/kg/day for 14 days (female) or 15 days (male) prior to cohabitation, during cohabitation, until the day prior to scheduled sacrifice (male) or through GD 7 (female). There were no adverse effects on fertility, mating performance or early embryonic development up to the highest dose tested, corresponding to 45-fold the human exposure at the RHD, based on AUC.

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.

The safety and effectiveness of LIPFENDRA have not been established in pediatric patients.

Of the 2,137 patients treated with LIPFENDRA in placebo-controlled trials, 960 (45%) patients were 65 years of age and older, and 252 (12%) patients were 75 years of age and older. No overall differences in safety or effectiveness were observed between patients 65 years of age and older and younger adult patients.

The frequencies of adverse reactions in adults with hypercholesterolemia were similar between those treated with LIPFENDRA and those receiving placebo. The most common adverse reactions in a study of adults with HeFH treated with LIPFENDRA were diarrhea and dizziness.

Adverse Reactions in Adults with Hypercholesterolemia The safety of LIPFENDRA was evaluated in Trial 1 (CORALreef Lipids, NCT05952856), a 52-week, multicenter, double-blind, randomized, placebo-controlled trial in 2,904 patients with hypercholesterolemia (including those with and without HeFH) and a history of a major atherosclerotic cardiovascular disease (ASCVD) event or increased risk for development of a first major ASCVD event [see Clinical Studies (14) ] . In Trial 1, the frequencies of adverse reactions in adults with hypercholesterolemia were similar between those treated with LIPFENDRA and those receiving placebo. Similar proportions of LIPFENDRA-treated patients and placebo-treated patients discontinued treatment because of an adverse reaction. Adverse Reactions in Adults with HeFH The safety of LIPFENDRA was evaluated in Trial 2 (CORALreef HeFH, NCT05952869), a 52-week multicenter, double-blind, randomized, placebo-controlled trial in 303 patients with HeFH [see Clinical Studies (14) ] . In Trial 2, the most common adverse reactions in adults with HeFH treated with LIPFENDRA that occurred at higher frequencies compared to placebo were diarrhea (LIPFENDRA 7%, placebo 2%) and dizziness (LIPFENDRA 9%, placebo 4%). Similar proportions of LIPFENDRA-treated patients and placebo-treated patients discontinued treatment because of an adverse reaction. The safety profile observed in adults with HeFH in Trial 2 was otherwise generally consistent with that observed in adults with hypercholesterolemia in Trial 1.

There is no specific treatment for overdose with LIPFENDRA. In the event of an overdose of LIPFENDRA, consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdosage management recommendations.
