1 INDICATIONS AND USAGE Therapy with lipid-altering agents should be only one component of multiple risk factor intervention in individuals at significantly increased risk for atherosclerotic vascular disease due to hypercholesterolemia. Drug therapy is indicated as an adjunct to diet when the response to a diet restricted in saturated fat and cholesterol and other nonpharmacologic measures alone has been inadequate. Ezetimibe and simvastatin tablets, which contains a cholesterol absorption inhibitor and an HMG-CoA reductase inhibitor (statin), is indicated as adjunctive therapy to diet to: • reduce elevated total-C, LDL-C, Apo B, TG, and non-HDL-C, and to increase HDL-C in patients with primary (heterozygous familial and non-familial) hyperlipidemia or mixed hyperlipidemia. ( 1.1 ) • reduce elevated total-C and LDL-C in patients with homozygous familial hypercholesterolemia (HoFH), as an adjunct to other lipid-lowering treatments. ( 1.2 ) Limitations of Use ( 1.3 ) • No incremental benefit of ezetimibe and simvastatin tablets on cardiovascular morbidity and mortality over and above that demonstrated for simvastatin has been established. • Ezetimibe and simvastatin tablets have not been studied in Fredrickson Type I, III, IV, and V dyslipidemias. 1.1 Primary Hyperlipidemia Ezetimibe and simvastatin tablets are indicated for the reduction of elevated total cholesterol (total-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein B (Apo B), triglycerides (TG), and non-high-density lipoprotein cholesterol (non-HDL-C), and to increase high-density lipoprotein cholesterol (HDL-C) in patients with primary (heterozygous familial and non-familial) hyperlipidemia or mixed hyperlipidemia. 1.2 Homozygous Familial Hypercholesterolemia (HoFH) Ezetimibe and simvastatin tablets are indicated for the reduction of elevated total-C and LDL-C in patients with homozygous familial hypercholesterolemia, as an adjunct to other lipid-lowering treatments (e.g., LDL apheresis) or if such treatments are unavailable. 1.3 Limitations of Use No incremental benefit of ezetimibe and simvastatin tablets on cardiovascular morbidity and mortality over and above that demonstrated for simvastatin has been established. Ezetimibe and simvastatin tablets have not been studied in Fredrickson type I, III, IV, and V dyslipidemias.

2 DOSAGE AND ADMINISTRATION • Dose range is 10/10 mg/day to 10/40 mg/day. ( 2.1 ) • Recommended usual starting dose is 10/10 or 10/20 mg/day. ( 2.1 ) • Due to the increased risk of myopathy, including rhabdomyolysis, use of the 10/80 mg dose of ezetimibe and simvastatin tablets should be restricted to patients who have been taking ezetimibe and simvastatin tablets 10/80 mg chronically (e.g., for 12 months or more) without evidence of muscle toxicity. ( 2.2 ) • Patients who are currently tolerating the 10/80 mg dose of ezetimibe and simvastatin tablets who need to be initiated on an interacting drug that is contraindicated or is associated with a dose cap for simvastatin should be switched to an alternative statin or statin-based regimen with less potential for the drug-drug interaction. ( 2.2 ) • Due to the increased risk of myopathy, including rhabdomyolysis, associated with the 10/80 mg dose of ezetimibe and simvastatin tablets, patients unable to achieve their LDL-C goal utilizing the 10/40 mg dose of ezetimibe and simvastatin tablets should not be titrated to the 10/80 mg dose, but should be placed on alternative LDL-C-lowering treatment(s) that provides greater LDL-C lowering. ( 2.2 ) • Dosing of ezetimibe and simvastatin tablets should occur either ≥2 hours before or ≥4 hours after administration of a bile acid sequestrant. ( 2.3 , Error! Hyperlink reference not valid. ) 2.1 Recommended Dosing The usual dosage range is 10/10 mg/day to 10/40 mg/day. The recommended usual starting dose is 10/10 mg/day or 10/20 mg/day. Ezetimibe and simvastatin tablets should be taken as a single daily dose in the evening, with or without food. Patients who require a larger reduction in LDL-C (greater than 55%) may be started at 10/40 mg/day in the absence of moderate to severe renal impairment (estimated glomerular filtration rate less than 60 mL/min/1.73 m 2 ). After initiation or titration of ezetimibe and simvastatin tablets, lipid levels may be analyzed after 2 or more weeks and dosage adjusted, if needed. 2.2 Restricted Dosing for 10/80 mg Due to the increased risk of myopathy, including rhabdomyolysis, particularly during the first year of treatment, use of the 10/80 mg dose of ezetimibe and simvastatin tablets should be restricted to patients who have been taking ezetimibe and simvastatin tablets 10/80 mg chronically (e.g., for 12 months or more) without evidence of muscle toxicity [see Warnings and Precautions ( 5.1 )] . Patients who are currently tolerating the 10/80 mg dose of ezetimibe and simvastatin tablets who need to be initiated on an interacting drug that is contraindicated or is associated with a dose cap for simvastatin should be switched to an alternative statin or statin-based regimen with less potential for the drug-drug interaction. Due to the increased risk of myopathy, including rhabdomyolysis, associated with the 10/80 mg dose of ezetimibe and simvastatin tablets, patients unable to achieve their LDL-C goal utilizing the 10/40 mg dose of ezetimibe and simvastatin tablets should not be titrated to the 10/80 mg dose, but should be placed on alternative LDL-C-lowering treatment(s) that provides greater LDL-C lowering. 2.3 Coadministration with Other Drugs Patients taking Verapamil, Diltiazem, or Dronedarone • The dose of ezetimibe and simvastatin tablets should not exceed 10/10 mg/day [see Warnings and Precautions ( 5.1 ), Drug Interactions ( Error! Hyperlink reference not valid. ), and Clinical Pharmacology ( 12.3 )]. Patients taking Amiodarone, Amlodipine or Ranolazine • The dose of ezetimibe and simvastatin tablets should not exceed 10/20 mg/day [see Warnings and Precautions ( 5.1 ), Drug Interactions ( Error! Hyperlink reference not valid. ), and Clinical Pharmacology ( 12.3 )]. Patients taking Bile Acid Sequestrants • Dosing of ezetimibe and simvastatin tablets should occur either greater than or equal to 2 hours before or greater than or equal to 4 hours after administration of a bile acid sequestrant [see Drug …

4 CONTRAINDICATIONS Ezetimibe and simvastatin tablets are contraindicated in the following conditions: • Concomitant administration of strong CYP3A4 inhibitors (e.g., itraconazole, ketoconazole, posaconazole, voriconazole, HIV protease inhibitors, boceprevir, telaprevir, erythromycin, clarithromycin, telithromycin, nefazodone, and cobicistat-containing products) [see Warnings and Precautions ( 5.1 )]. • Concomitant administration of gemfibrozil, cyclosporine, or danazol [see Warnings and Precautions ( 5.1 )]. • Hypersensitivity to any component of this medication [see Adverse Reactions ( Error! Hyperlink reference not valid. )]. • Active liver disease or unexplained persistent elevations in hepatic transaminase levels [see Warnings and Precautions ( 5.3 )]. • Women who are pregnant or may become pregnant . Serum cholesterol and triglycerides increase during normal pregnancy, and cholesterol or cholesterol derivatives are essential for fetal development. Because HMG-CoA reductase inhibitors (statins), such as simvastatin, decrease cholesterol synthesis and possibly the synthesis of other biologically active substances derived from cholesterol, ezetimibe and simvastatin may cause fetal harm when administered to a pregnant woman. Atherosclerosis is a chronic process and the discontinuation of lipid-lowering drugs during pregnancy should have little impact on the outcome of long-term therapy of primary hypercholesterolemia. There are no adequate and well-controlled studies of ezetimibe and simvastatin use during pregnancy; however, in rare reports congenital anomalies were observed following intrauterine exposure to statins. In rat and rabbit animal reproduction studies, simvastatin revealed no evidence of teratogenicity. Ezetimibe and simvastatin should be administered to women of childbearing age only when such patients are highly unlikely to conceive. If the patient becomes pregnant while taking this drug, ezetimibe and simvastatin should be discontinued immediately and the patient should be apprised of the potential hazard to the fetus [see Use in Specific Populations ( 8.1 )]. • Nursing mothers. It is not known whether simvastatin is excreted into human milk; however, a small amount of another drug in this class does pass into breast milk. Because statins have the potential for serious adverse reactions in nursing infants, women who require ezetimibe and simvastatin treatment should not breastfeed their infants [see Use in Specific Populations ( Error! Hyperlink reference not valid. )]. • Concomitant administration of strong CYP3A4 inhibitors. ( 4 , 5.1 ) • Concomitant administration of gemfibrozil, cyclosporine, or danazol. ( 4 , 5.1 ) • Hypersensitivity to any component of this medication ( 4 , Error! Hyperlink reference not valid. ) • Active liver disease or unexplained persistent elevations of hepatic transaminase levels ( 4 , 5.3 ) • Women who are pregnant or may become pregnant ( 4 , 8.1 ) • Nursing mothers ( 4 , Error! Hyperlink reference not valid. )

6 ADVERSE REACTIONS The following serious adverse reactions are discussed in greater detail in other sections of the label: • Rhabdomyolysis and myopathy [see Warnings and Precautions ( 5.1 )] • Liver enzyme abnormalities [see Warnings and Precautions ( 5.3 )] • Common (incidence ≥2% and greater than placebo) adverse reactions in clinical trials: headache, increased ALT, myalgia, upper respiratory tract infection, and diarrhea.

In the ezetimibe and simvastatin tablets placebo-controlled clinical trials database of 1420 patients (age range 20 to 83 years, 52% women, 87% Caucasians, 3% Blacks, 5% Hispanics, 3% Asians) with a median treatment duration of 27 weeks, 5% of patients on ezetimibe and simvastatin tablets and 2.2% of patients on placebo discontinued due to adverse reactions. The most common adverse reactions in the group treated with ezetimibe and simvastatin tablets that led to treatment discontinuation and occurred at a rate greater than placebo were: • Increased ALT (0.9%) • Myalgia (0.6%) • Increased AST (0.4%) • Back pain (0.4%) The most commonly reported adverse reactions (incidence ≥2% and greater than placebo) in controlled clinical trials were: headache (5.8%), increased ALT (3.7%), myalgia (3.6%), upper respiratory tract infection (3.6%), and diarrhea (2.8%). Ezetimibe and simvastatin tablets have been evaluated for safety in more than 10,189 patients in clinical trials. Table 2 summarizes the frequency of clinical adverse reactions reported in ≥2% of patients treated with ezetimibe and simvastatin tablets (n=1420) and at an incidence greater than placebo, regardless of causality assessment, from four placebo-controlled trials.

Study of Heart and Renal Protection In SHARP , 9270 patients were allocated to ezetimibe and simvastatin tablets 10/20 mg daily (n=4650) or placebo (n=4620) for a median follow-up period of 4.9 years. The proportion of patients who permanently discontinued study treatment as a result of either an adverse event or abnormal safety blood result was 10.4% vs. 9.8% among patients allocated to ezetimibe and simvastatin tablets and placebo, respectively. Comparing those allocated to ezetimibe and simvastatin tablets vs. placebo, the incidence of myopathy (defined as unexplained muscle weakness or pain with a serum CK >10 times ULN) was 0.2% vs. 0.1% and the incidence of rhabdomyolysis (defined as myopathy with a CK >40 times ULN) was 0.09% vs. 0.02%, respectively. Consecutive elevations of transaminases (>3 X ULN) occurred in 0.7% vs. 0.6%, respectively. Patients were asked about the occurrence of unexpl …

7 DRUG INTERACTIONS Ezetimibe and Simvastatin Tablets See full prescribing information for details regarding concomitant use of ezetimibe and simvastatin with other drugs or grapefruit juice that increase the risk of myopathy and rhabdomyolysis. ( 2.3 , 7.1 ) Cholestyramine: Combination decreases exposure of ezetimibe. ( 2.3 , 7.2 ) Coumarin Anticoagulants: Obtain INR before ezetimibe and simvastatin initiation and monitor INR during ezetimibe and simvastatin dosage initiation or adjustment. ( 7.3 ) Digoxin: During ezetimibe and simvastatin initiation, monitor digoxin levels. ( 7.3 ) Fenofibrates: Combination increases exposure of ezetimibe. If cholelithiasis is suspected in a patient receiving ezetimibe and a fenofibrate, gallbladder studies are indicated and alternative lipid-lowering therapy should be considered. ( 7.3 , 12.3 ) 7.1Drug Interactions that Increase the Risk of Myopathy and Rhabdomyolysis with ezetimibe and simvastatin tablets Ezetimibe and simvastatin tablets is a substrate of CYP3A4 and of the transport protein OATP1B1. Ezetimibe and simvastatin tablets plasma levels can be significantly increased with concomitant administration of inhibitors of CYP3A4 and OATP1B1. Table 2 includes a list of drugs that increase the risk of myopathy and rhabdomyolysis when used concomitantly with ezetimibe and simvastatin tablets and instructions for preventing or managing them [see Warnings and Precautions ( 5.1 ) and Clinical Pharmacology ( 12.3 )]. Table 2: Drug Interactions that Increase the Risk of Myopathy and Rhabdomyolysis with Ezetimibe and Simvastatin Tablets Strong CYP3A4 inhibitors Clinical Impact: Simvastatin is a substrate of CYP3A4. Concomitant use of strong CYP3A4 inhibitors with ezetimibe and simvastatin tablets increases simvastatin exposure and increases the risk of myopathy and rhabdomyolysis, particularly with higher ezetimibe and simvastatin tablets dosages. Intervention: Concomitant use of strong CYP3A4 inhibitors with ezetimibe and simvastatin tablets is contraindicated [see Contraindications (4)] . If treatment with a CYP3A4 inhibitor is unavoidable, suspend ezetimibe and simvastatin tablets during the course of strong CYP3A4 inhibitor treatment. Examples: Select azole anti-fungals (e.g., itraconazole, ketoconazole, posaconazole, and voriconazole), select macrolide antibiotics (e.g., erythromycin and clarithromycin, telithromycin), select HIV protease inhibitors (e.g., nelfinavir, ritonavir, and darunavir/ritonavir), select HCV protease inhibitors (e.g., boceprevir and telaprevir), cobicistat-containing products, and nefazodone. Cyclosporine, Danazol, or Gemfibrozil Clinical Impact: The risk of myopathy and rhabdomyolysis is increased with concomitant use of cyclosporine, danazol, or gemfibrozil with ezetimibe and simvastatin tablets. Gemfibrozil may cause myopathy when given alone. Intervention: Concomitant use of cyclosporine, danazol, or gemfibrozil with ezetimibe and simvastatin tablets is contraindicated [see Contraindications (4)] . Amiodarone, Dronedarone, Ranolazine, or Calcium Channel Blockers Clinical Impact: The risk of myopathy and rhabdomyolysis is increased by concomitant use of amiodarone, dronedarone, ranolazine, or calcium channel blockers with ezetimibe and simvastatin tablets. Intervention: For patients taking verapamil, diltiazem, or dronedarone, do not exceed ezetimibe and simvastatin tablets 10/10 mg daily . For patients taking amiodarone, amlodipine, or ranolazine, do not exceed ezetimibe and simvastatin tablets10/20 mg daily [see Dosage and Administration (2.3)] . Lomitapide Clinical Impact: Simvastatin exposure is approximately doubled with concomitant use of lomitapide and the risk of myopathy and rhabdomyolysis is increased . Intervention: Reduce the dose of ezetimibe and simvastatin tablets by 50% if initiating lomitapide. Do not exceed ezetimibe and simvastatin tablets 10/20 mg daily (or ezetimibe and simvastatin tablets 10/40 mg daily for patients who have previously taken …

8 USE IN SPECIFIC POPULATIONS Pregnancy: May cause fetal harm (8.1) Lactation: Breastfeeding not recommended during treatment with ezetimibe and simvastatin. ( 8.2 ) 8.1 Pregnancy Ezetimibe and Simvastatin Risk Summary Discontinue ezetimibe and simvastatin when pregnancy is recognized. Alternatively, consider the ongoing therapeutic needs of the individual patient. Ezetimibe and simvastatin decreases synthesis of cholesterol and possibly other biologically active substances derived from cholesterol; therefore, ezetimibe and simvastatin may cause fetal harm when administered to pregnant patients based on the mechanism of action [see Clinical Pharmacology (12.1) ] . In addition, treatment of hyperlipidemia is not generally necessary during pregnancy. Atherosclerosis is a chronic process and the discontinuation of lipid-lowering drugs during pregnancy should have little impact on the outcome of long-term therapy of primary hyperlipidemia for most patients. Available data from case series and prospective and retrospective observational cohort studies over decades of use with statins in pregnant women have not identified a drug-associated risk of major congenital malformations. Published data from prospective and retrospective observational cohort studies with ezetimibe and simvastatin use in pregnant women are insufficient to determine if there is a drug-associated risk of miscarriage (see Data) . In animal reproduction studies, no adverse developmental effects were observed in pregnant rats or rabbits orally administered simvastatin during the period of organogenesis at doses that resulted in 2.5 and 2 times, respectively, the human exposure at the maximum recommended human dosage of 80 mg/day, based on body surface area (mg/m 2 ). In animal reproduction studies, no adverse developmental effects were observed in pregnant rats and rabbits orally administered ezetimibe during the period of organogenesis at doses that resulted in up to 10 and 150 times, respectively, the human exposure at the MRHD, 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 Human Data Ezetimibe There are insufficient data on ezetimibe use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Simvastatin A Medicaid cohort linkage trial of 1152 statin-exposed pregnant women compared to 886,996 controls did not find a significant teratogenic effect from maternal use of statins in the first trimester of pregnancy, after adjusting for potential confounders – including maternal age, diabetes mellitus, hypertension, obesity, and alcohol and tobacco use – using propensity score-based methods. The relative risk of congenital malformations between the group with statin use and the group with no statin use in the first trimester was 1.07 (95% confidence interval 0.85 to 1.37) after controlling for confounders, particularly pre-existing diabetes mellitus. There were also no statistically significant increases in any of the organ-specific malformations assessed after accounting for confounders. In the majority of pregnancies, statin treatment was initiated prior to pregnancy and was discontinued at some point in the first trimester when pregnancy was identified. Trial limitations include reliance on physician coding to define the presence of a malformation, lack of control for certain confounders such as body mass index, use of prescription dispensing as verification for the use of a statin, and lack of information on non-live births. Animal Data Ezetimibe In oral (gavage) embryo-fetal development studies of ezetimibe conducted in rats (gestation days 6 to 15) and rabbits (gestation days 7 to 19), there was no evidence of maternal …

12.1 Mechanism of Action Ezetimibe and Simvastatin Tablets Plasma cholesterol is derived from intestinal absorption and endogenous synthesis. Ezetimibe and simvastatin tablets contain ezetimibe and simvastatin, two lipid-lowering compounds with complementary mechanisms of action. Ezetimibe and simvastatin tablets reduce elevated total-C, LDL-C, Apo B, TG, and non-HDL-C, and increases HDL-C through dual inhibition of cholesterol absorption and synthesis. Ezetimibe Ezetimibe reduces blood cholesterol by inhibiting the absorption of cholesterol by the small intestine. The molecular target of ezetimibe has been shown to be the sterol transporter, Niemann-Pick C1-Like 1 (NPC1L1), which is involved in the intestinal uptake of cholesterol and phytosterols. In a 2 week clinical study in 18 hypercholesterolemic patients, ezetimibe inhibited intestinal cholesterol absorption by 54%, compared with placebo. Ezetimibe had no clinically meaningful effect on the plasma concentrations of the fat-soluble vitamins A, D, and E and did not impair adrenocortical steroid hormone production. Ezetimibe localizes at the brush border of the small intestine and inhibits the absorption of cholesterol, leading to a decrease in the delivery of intestinal cholesterol to the liver. This causes a reduction of hepatic cholesterol stores and an increase in clearance of cholesterol from the blood; this distinct mechanism is complementary to that of statins [ see Clinical Studies ( 14 ) ]. Simvastatin Simvastatin is a prodrug and is hydrolyzed to its active β-hydroxyacid form, simvastatin acid, after administration. Simvastatin is a specific inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase, the enzyme that catalyzes the conversion of HMG-CoA to mevalonate, an early and rate limiting step in the biosynthetic pathway for cholesterol. In addition, simvastatin reduces very-low-density lipoproteins (VLDL) and TG and increases HDL-C.

10 OVERDOSAGE Ezetimibe and Simvastatin Tablets No specific treatment of overdosage with ezetimibe and simvastatin tablets can be recommended. In the event of an overdose, symptomatic and supportive measures should be employed. Ezetimibe In clinical studies, administration of ezetimibe, 50 mg/day to 15 healthy subjects for up to 14 days, or 40 mg/day to 18 patients with primary hyperlipidemia for up to 56 days, was generally well tolerated. A few cases of overdosage have been reported; most have not been associated with adverse experiences. Reported adverse experiences have not been serious. Simvastatin Significant lethality was observed in mice after a single oral dose of 9 g/m 2 . No evidence of lethality was observed in rats or dogs treated with doses of 30 and 100 g/m 2 , respectively. No specific diagnostic signs were observed in rodents. At these doses the only signs seen in dogs were emesis and mucoid stools. A few cases of overdosage with simvastatin have been reported; the maximum dose taken was 3.6 g. All patients recovered without sequelae. The dialyzability of simvastatin and its metabolites in man is not known at present.
