8 USE IN SPECIFIC POPULATIONS. Moderate to severe renal impairment: Doses exceeding 10/20 mg/day should be used with caution and close monitoring 2.5, 8.6). Chinese patients: May be at higher risk of myopathy; monitor appropriately 5.1, 8.8). Moderate to severe renal impairment: Doses exceeding 10/20 mg/day should be used with caution and close monitoring 2.5, 8.6). Chinese patients: May be at higher risk of myopathy; monitor appropriately 5.1, 8.8). 8.1 Pregnancy. Pregnancy Category X.[See Contraindications (4)].Ezetimibe and simvastatinEzetimibe and simvastatin is contraindicated in women who are or may become pregnant. Lipid-lowering drugs offer no benefit during pregnancy, because cholesterol and cholesterol derivatives are needed for normal fetal development. Atherosclerosis is chronic process, and discontinuation of lipid-lowering drugs during pregnancy should have little impact on long-term outcomes of primary hypercholesterolemia therapy. There are no adequate and well-controlled studies of ezetimibe and simvastatin use during pregnancy; however, there are rare reports of congenital anomalies in infants exposed to statins in utero. Animal reproduction studies of simvastatin in rats and rabbits showed no evidence of teratogenicity. Serum cholesterol and triglycerides increase during normal pregnancy, and cholesterol or cholesterol derivatives are essential for fetal development. Because 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 pregnant woman. If ezetimibe and simvastatin is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus. Women of childbearing potential, who require ezetimibe and simvastatin treatment for lipid disorder, should be advised to use effective contraception. For women trying to conceive, discontinuation of ezetimibe and simvastatin should be considered. If pregnancy occurs, ezetimibe and simvastatin should be immediately discontinued.EzetimibeIn oral (gavage) embryo-fetal development studies of ezetimibe conducted in rats and rabbits during organogenesis, there was no evidence of embryolethal effects at the doses tested (250, 500, 1,000 mg/kg/day). In rats, increased incidences of common fetal skeletal findings (extra pair of thoracic ribs, unossified cervical vertebral centra, shortened ribs) were observed at 1,000 mg/kg/day (~10 times the human exposure at 10 mg daily based on AUC 0-24hr for total ezetimibe). In rabbits treated with ezetimibe, an increased incidence of extra thoracic ribs was observed at 1,000 mg/kg/day (150 times the human exposure at 10 mg daily based on AUC 0-24hr for total ezetimibe). Ezetimibe crossed the placenta when pregnant rats and rabbits were given multiple oral doses. Multiple-dose studies of ezetimibe co-administered with statins in rats and rabbits during organogenesis result in higher ezetimibe and statin exposures. Reproductive findings occur at lower doses in co-administration therapy compared to monotherapy.SimvastatinSimvastatin was not teratogenic in rats or rabbits at doses (25 mg/kg/day, 10 mg/kg/day, respectively) that resulted in times the human exposure based on mg/m surface area. However, in studies with another structurally-related statin, skeletal malformations were observed in rats and mice. There are rare reports of congenital anomalies following intrauterine exposure to statins. In review of approximately 100 prospectively followed pregnancies in women exposed to simvastatin or another structurally-related statin, the incidences of congenital anomalies, spontaneous abortions and fetal deaths/stillbirths did not exceed what would be expected in the general population. The number of cases is adequate only to exclude 3- to 4-fold increase in congenital anomalies over the background incidence. In 89% of the prospectively followed pregnancies, drug treatment was initiated prior to pregnancy and was discontinued at some point in the first trimester when pregnancy was identified. Manson, J.M., Freyssinges, C., Ducrocq, M.B., Stephenson, W.P., Postmarketing Surveillance of Lovastatin and Simvastatin Exposure During Pregnancy, Reproductive Toxicology, 10(6):439-446, 1996. 8.3 Nursing Mothers. It is not known whether simvastatin is excreted in human milk. Because small amount of another drug in this class is excreted in human milk and because of the potential for serious adverse reactions in nursing infants, women taking simvastatin should not nurse their infants. decision should be made whether to discontinue nursing or discontinue drug, taking into account the importance of the drug to the mother [see Contraindications (4)]. In rat studies, exposure to ezetimibe in nursing pups was up to half of that observed in maternal plasma. It is not known whether ezetimibe or simvastatin are excreted into human breast milk. Because small amount of another drug in the same class as simvastatin is excreted in human milk and because of the potential for serious adverse reactions in nursing infants, women who are nursing should not take ezetimibe and simvastatin [see Contraindications (4)]. 8.4 Pediatric Use. The effects of ezetimibe co-administered with simvastatin (n=126) compared to simvastatin monotherapy (n=122) have been evaluated in adolescent boys and girls with heterozygous familial hypercholesterolemia (HeFH). In multicenter, double-blind, controlled study followed by an open-label phase, 142 boys and 106 postmenarchal girls, 10 to 17 years of age (mean age 14.2 years, 43% females, 82% Caucasians, 4% Asian, 2% Blacks, 13% multiracial) with HeFH were randomized to receive either ezetimibe co-administered with simvastatin or simvastatin monotherapy. Inclusion in the study required 1) baseline LDL-C level between 160 and 400 mg/dL and 2) medical history and clinical presentation consistent with HeFH. The mean baseline LDL-C value was 225 mg/dL (range: 161 mg/dL to 351 mg/dL) in the ezetimibe co-administered with simvastatin group compared to 219 mg/dL (range: 149 mg/dL to 336 mg/dL) in the simvastatin monotherapy group. The patients received co-administered ezetimibe and simvastatin (10 mg, 20 mg, or 40 mg) or simvastatin monotherapy (10 mg, 20 mg, or 40 mg) for weeks, co-administered ezetimibe and 40 mg simvastatin or 40 mg simvastatin monotherapy for the next 27 weeks, and open-label co-administered ezetimibe and simvastatin (10 mg, 20 mg, or 40 mg) for 20 weeks thereafter.The results of the study at Week are summarized in Table 3. Results at Week 33 were consistent with those at Week 6.Table 3: Mean Percent Difference at Week Between the Pooled Ezetimibe Co-administered with Simvastatin Group and the Pooled Simvastatin Monotherapy Group in Adolescent Patients with Heterozygous Familial HypercholesterolemiaTotal-CLDL-CApo BNon-HDL-CTG HDL-CMean percent difference between treatment groups-12%-15%-12%-14%-2%+0.1%95% Confidence Interval(-15%, -9%)(-18%, -12%)(-15%, -9%)(-17%, -11%)(-9, +4)(-3, +3) For triglycerides, median change from baseline. From the start of the trial to the end of Week 33, discontinuations due to an adverse reaction occurred in (6%) patients in the ezetimibe co-administered with simvastatin group and in (2%) patients in the simvastatin monotherapy group.During the trial, hepatic transaminase elevations (two consecutive measurements for ALT and/or AST >=3 ULN) occurred in four (3%) individuals in the ezetimibe co-administered with simvastatin group and in two (2%) individuals in the simvastatin monotherapy group. Elevations of CPK (>=10 ULN) occurred in two (2%) individuals in the ezetimibe co-administered with simvastatin group and in zero individuals in the simvastatin monotherapy group.In this limited controlled study, there was no significant effect on growth or sexual maturation in the adolescent boys or girls, or on menstrual cycle length in girls.Co-administration of ezetimibe with simvastatin at doses greater than 40 mg/day has not been studied in adolescents. Also, ezetimibe and simvastatin has not been studied in patients younger than 10 years of age or in pre-menarchal girls.EzetimibeBased on total ezetimibe (ezetimibe ezetimibe-glucuronide) there are no pharmacokinetic differences between adolescents and adults. Pharmacokinetic data in the pediatric population <10 years of age are not available.SimvastatinThe pharmacokinetics of simvastatin has not been studied in the pediatric population.. 8.5 Geriatric Use. Of the 10,189 patients who received ezetimibe and simvastatin in clinical studies, 3,242 (32%) were 65 and older (this included 844 (8%) who were 75 and older). No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients but greater sensitivity of some older individuals cannot be ruled out. Since advanced age (>=65 years) is predisposing factor for myopathy, ezetimibe and simvastatin should be prescribed with caution in the elderly [see Clinical Pharmacology (12.3)]. Because advanced age (>=65 years) is predisposing factor for myopathy, including rhabdomyolysis, ezetimibe and simvastatin should be prescribed with caution in the elderly. In clinical trial of patients treated with simvastatin 80 mg/day, patients >=65 years of age had an increased risk of myopathy, including rhabdomyolysis, compared to patients <65 years of age [see Warnings and Precautions (5.1) and Clinical Pharmacology (12.3) ]. 8.6 Renal Impairment. In the SHARP trial of 9,270 patients with moderate to severe renal impairment (6,247 non-dialysis patients with median serum creatinine 2.5 mg/dL and median estimated glomerular filtration rate 25.6 mL/min/1.73 2, and 3,023 dialysis patients), the incidence of serious adverse events, adverse events leading to discontinuation of study treatment, or adverse events of special interest (musculoskeletal adverse events, liver enzyme abnormalities, incident cancer) was similar between patients ever assigned to ezetimibe and simvastatin 10/20 mg (n=4,650) or placebo (n=4,620) during median follow-up of 4.9 years. However, because renal impairment is risk factor for statin-associated myopathy, doses of ezetimibe and simvastatin exceeding 10/20 mg should be used with caution and close monitoring in patients with moderate to severe renal impairment [see Dosage and Administration (2.5), Adverse Reactions (6.1), and Clinical Studies (14.3)] . 8.7 Hepatic Impairment. Ezetimibe and simvastatin is contraindicated in patients with active liver disease or unexplained persistent elevations in hepatic transaminases [see Contraindications (4) and Warnings and Precautions (5.3)] . 8.8 ChinesePatients. In clinical trial in which patients at high risk of cardiovascular disease were treated with simvastatin 40 mg/day (median follow-up 3.9 years), the incidence of myopathy was approximately 0.05% for non-Chinese patients (n=7,367) compared with 0.24% for Chinese patients (n=5,468). The incidence of myopathy for Chinese patients on simvastatin 40 mg/day or ezetimibe and simvastatin 10/40 mg/day co-administered with extended-release niacin g/day was 1.24%.Chinese patients may be at higher risk for myopathy, monitor patients appropriately. Co-administration of ezetimibe and simvastatin with lipid-modifying doses (>=1 g/day niacin) of niacin-containing products is not recommended in Chinese patients [see Warnings and Precautions (5.1), Drug Interactions (7.4)].

WARNINGS AND PRECAUTIONS SECTION.

5 WARNINGS AND PRECAUTIONS. Patients should be advised of the increased risk of myopathy, including rhabdomyolysis, with the 10/80-mg dose. 5.1) Patients should be advised to report promptly any unexplained and/or persistent muscle pain, tenderness, or weakness. Ezetimibe and simvastatin tablets should be discontinued immediately if myopathy is diagnosed or suspected. 5.1) Skeletal muscle effects (e.g., myopathy and rhabdomyolysis): Risks increase with higher doses and concomitant use of certain medicines. Predisposing factors include advanced age (>=65), female gender, uncontrolled hypothyroidism, and renal impairment. Rare cases of rhabdomyolysis with acute renal failure secondary to myoglobinuria have been reported. (4, 5.1, 8.5, 8.6) Immune-Mediated Necrotizing Myopathy (IMNM): There have been rare reports of IMNM, an autoimmune myopathy, associated with statin use. IMNM is characterized by: proximal muscle weakness and elevated serum creatine kinase, which persist despite discontinuation of statin treatment; positive anti-HMG CoA reductase antibody; muscle biopsy showing necrotizing myopathy; and improvement with immunosuppressive agents. (5.2) Liver enzyme abnormalities: Persistent elevations in hepatic transaminases can occur. Check liver enzyme tests before initiating therapy and as clinically indicated thereafter. 5.3) Patients should be advised of the increased risk of myopathy, including rhabdomyolysis, with the 10/80-mg dose. 5.1) Patients should be advised to report promptly any unexplained and/or persistent muscle pain, tenderness, or weakness. Ezetimibe and simvastatin tablets should be discontinued immediately if myopathy is diagnosed or suspected. 5.1) Skeletal muscle effects (e.g., myopathy and rhabdomyolysis): Risks increase with higher doses and concomitant use of certain medicines. Predisposing factors include advanced age (>=65), female gender, uncontrolled hypothyroidism, and renal impairment. Rare cases of rhabdomyolysis with acute renal failure secondary to myoglobinuria have been reported. (4, 5.1, 8.5, 8.6) Immune-Mediated Necrotizing Myopathy (IMNM): There have been rare reports of IMNM, an autoimmune myopathy, associated with statin use. IMNM is characterized by: proximal muscle weakness and elevated serum creatine kinase, which persist despite discontinuation of statin treatment; positive anti-HMG CoA reductase antibody; muscle biopsy showing necrotizing myopathy; and improvement with immunosuppressive agents. (5.2) Liver enzyme abnormalities: Persistent elevations in hepatic transaminases can occur. Check liver enzyme tests before initiating therapy and as clinically indicated thereafter. 5.3) 5.1 Myopathy/Rhabdomyolysis. Simvastatin occasionally causes myopathy manifested as muscle pain, tenderness or weakness with creatine kinase above ten times the upper limit of normal (ULN). Myopathy sometimes takes the form of rhabdomyolysis with or without acute renal failure secondary to myoglobinuria, and rare fatalities have occurred. The risk of myopathy is increased by elevated plasma levels of simvastatin and simvastatin acid. Predisposing factors for myopathy include advanced age (>=65 years), female gender, uncontrolled hypothyroidism, and renal impairment. Chinese patients may be at increased risk for myopathy [see Use in Specific Populations (8.8)] The risk of myopathy, including rhabdomyolysis, is dose related. In clinical trial database in which 41,413 patients were treated with simvastatin, 24,747 (approximately 60%) of whom were enrolled in studies with median follow-up of at least years, the incidence of myopathy was approximately 0.03% and 0.08% at 20 and 40 mg/day, respectively. The incidence of myopathy with 80 mg (0.61%) was disproportionately higher than that observed at the lower doses. In these trials, patients were carefully monitored and some interacting medicinal products were excluded. In clinical trial in which 12,064 patients with history of myocardial infarction were treated with simvastatin (mean follow-up 6.7 years), the incidence of myopathy (defined as unexplained muscle weakness or pain with serum creatine kinase [CK] >10 times upper limit of normal [ULN]) in patients on 80 mg/day was approximately 0.9% compared with 0.02% for patients on 20 mg/day. The incidence of rhabdomyolysis (defined as myopathy with CK >40 times ULN) in patients on 80 mg/day was approximately 0.4% compared with 0% for patients on 20 mg/day. The incidence of myopathy, including rhabdomyolysis, was highest during the first year and then notably decreased during the subsequent years of treatment. In this trial, patients were carefully monitored and some interacting medicinal products were excluded.The risk of myopathy, including rhabdomyolysis, is greater in patients on simvastatin 80 mg compared with other statin therapies with similar or greater LDL-C-lowering efficacy and compared with lower doses of simvastatin. Therefore, the 10/80-mg dose of ezetimibe and simvastatin should be used only in patients who have been taking ezetimibe and simvastatin 10/80 mg chronically (e.g., for 12 months or more) without evidence of muscle toxicity [see Dosage and Administration, Restricted Dosing for 10/80 mg 2.2)] If, however, patient who is currently tolerating the 10/80-mg dose of zetimibe and simvastatin needs to be initiated on an interacting drug that is contraindicated or is associated with dose cap for simvastatin, that patient should be switched to an alternative statin or statin-based regimen with less potential for the drug-drug interaction. Patients should be advised of the increased risk of myopathy, including rhabdomyolysis, and to report promptly any unexplained muscle pain, tenderness or weakness. If symptoms occur, treatment should be discontinued immediately [see Warnings and Precautions (5.2)] In the Study of Heart and Renal Protection (SHARP), 9,270 patients with chronic kidney disease were allocated to receive ezetimibe and simvastatin 10/20 mg daily (n=4,650) or placebo (n=4,620). During median follow-up period of 4.9 years, the incidence of myopathy (defined as unexplained muscle weakness or pain with serum creatine kinase [CK] >10 times upper limit of normal [ULN]) was 0.2% for ezetimibe and simvastatin and 0.1% for placebo: the incidence of rhabdomyolysis (defined as myopathy with CK 40 times ULN) was 0.09% for ezetimibe and simvastatin and 0.02% for placebo.In postmarketing experience with ezetimibe, cases of myopathy and rhabdomyolysis have been reported. Most patients who developed rhabdomyolysis were taking statin prior to initiating ezetimibe. However, rhabdomyolysis has been reported with ezetimibe monotherapy and with the addition of ezetimibe to agents known to be associated with increased risk of rhabdomyolysis, such as fibric acid derivatives. Ezetimibe and simvastatin and fenofibrate, if taking concomitantly, should both be immediately discontinued if myopathy is diagnosed or suspected.All patients starting therapy with ezetimibe and simvastatin or whose dose of ezetimibe and simvastatin is being increased should be advised of the risk of myopathy, including rhabdomyolysis, and told to report promptly any unexplained muscle pain, tenderness or weakness particularly if accompanied by malaise or fever or if muscle signs and symptoms persist after discontinuing ezetimibe and simvastatin. Ezetimibe and simvastatin therapy should be discontinued immediately if myopathy is diagnosed or suspected. In most cases, muscle symptoms and CK increases resolved when simvastatin treatment was promptly discontinued. Periodic CK determinations may be considered in patients starting therapy with ezetimibe and simvastatin or whose dose is being increased, but there is no assurance that such monitoring will prevent myopathy. Many of the patients who have developed rhabdomyolysis on therapy with simvastatin have had complicated medical histories, including renal insufficiency usually as consequence of long-standing diabetes mellitus. Such patients taking ezetimibe and simvastatin merit closer monitoring.Ezetimibe and simvastatin therapy should be discontinued if markedly elevated CPK levels occur or myopathy is diagnosed or suspected. Ezetimibe and simvastatin therapy should also be temporarily withheld in any patient experiencing an acute or serious condition predisposing to the development of renal failure secondary to rhabdomyolysis, e.g., sepsis; hypotension; major surgery; trauma; severe metabolic, endocrine, or electrolyte disorders; or uncontrolled epilepsy.Drug InteractionsThe risk of myopathy and rhabdomyolysis is increased by elevated plasma levels of simvastatin and simvastatin acid. Simvastatin is metabolized by the cytochrome P450 isoform 3A4. Certain drugs that inhibit this metabolic pathway can raise the plasma levels of simvastatin and may increase the risk of myopathy. These include itraconazole, ketoconazole, posaconazole, and voriconazole, the macrolide antibiotics erythromycin and clarithromycin, and the ketolide antibiotic telithromycin, HIV protease inhibitors, boceprevir, telaprevir, the antidepressant nefazodone, cobicistat-containing products, or grapefruit juice [see Clinical Pharmacology (12.3)]. Combination of these drugs with ezetimibe and simvastatin is contraindicated. If short-term treatment with strong CYP3A4 inhibitors is unavoidable, therapy with ezetimibe and simvastatin must be suspended during the course of treatment [see Contraindications (4) and Drug Interactions (7)]. The combined use of ezetimibe and simvastatin with gemfibrozil, cyclosporine, or danazol is contraindicated [see Contraindications (4) and Drug Interactions (7.1 and 7.2)] Caution should be used when prescribing fenofibrates with ezetimibe and simvastatin, as these agents can cause myopathy when given alone and the risk is increased when they are co-administered [see Drug Interactions (7.2, 7.7)] Cases of myopathy, including rhabdomyolysis, have been reported with simvastatin co-administered with colchicine, and caution should be exercised when prescribing ezetimibe and simvastatin with colchicine [see Drug Interactions (7.9)] The benefits of the combined use of ezetimibe and simvastatin with the following drugs should be carefully weighed against the potential risks of combinations: other lipid-lowering drugs (fenofibrates or, for patients with HoFH, lomitapide), amiodarone, dronedarone, verapamil, diltiazem, amlodipine, or ranolazine [see Dosage and Administration (2.4), Drug Interactions (7.3)] Cases of myopathy, including rhabdomyolysis, have been observed with simvastatin co-administered with lipid-modifying doses (>=1 g/day niacin) of niacin-containing products [see Drug Interactions (7.4)] Cases of rhabdomyolysis have been reported with ezetimibe and simvastatin administered with daptomycin. Temporarily suspend ezetimibe and simvastatin in patients taking daptomycin [see Drug Interactions (7.10)] Prescribing recommendations for interacting agents are summarized in Table [see also Dosage and Administration (2.3, 2.4), Drug Interactions (7) and Clinical Pharmacology (12.3)]. Table 1: Drug Interactions Associated with Increased Risk of Myopathy/RhabdomyolysisInteracting AgentsPrescribing RecommendationsStrong CYP3A4 Inhibitors, e.g.: Itraconazole Ketoconazole Posaconazole Voriconazole Erythromycin Clarithromycin Telithromycin HIV protease inhibitors Boceprevir Telaprevir Nefazodone Cobicistat-containing products Gemfibrozil Cyclosporine Danazol Contraindicated with ezetimibe and simvastatinNiacin (>=1 g/day)For Chinese patients, not recommended with ezetimibe and simvastatin Verapamil Diltiazem Dronedarone Do not exceed 10/10 mg ezetimibe and simvastatin dailyAmiodarone Amlodipine Ranolazine Do not exceed 10/20 mg ezetimibe and simvastatin dailyLomitapideFor patients with HoFH, do not exceed 10/20 mg ezetimibe and simvastatin dailyDaptomycinTemporarily suspend ezetimibe and simvastatinGrapefruit juiceAvoid grapefruit juice For patients with HoFH who have been taking 80 mg simvastatin chronically (e.g., for 12 months or more) without evidence of muscle toxicity, do not exceed 10/40 mg ezetimibe and simvastatin when taking lomitapide.. 5.2 Immune-MediatedNecrotizing Myopathy. There have been rare reports of immune-mediated necrotizing myopathy (IMNM), an autoimmune myopathy, associated with statin use. IMNM is characterized by: proximal muscle weakness and elevated serum creatine kinase, which persist despite discontinuation of statin treatment; positive anti-HMG CoA reductase antibody; muscle biopsy showing necrotizing myopathy; and improvement with immunosuppressive agents. Additional neuromuscular and serologic testing may be necessary. Treatment with immunosuppressive agents may be required. Consider risk of IMNM carefully prior to initiation of different statin. If therapy is initiated with different statin, monitor for signs and symptoms of IMNM.. 5.3 Liver Enzymes. In three placebo-controlled, 12-week trials, the incidence of consecutive elevations (>=3 ULN) in serum transaminases was 1.7% overall for patients treated with ezetimibe and simvastatin and appeared to be dose-related with an incidence of 2.6% for patients treated with ezetimibe and simvastatin 10/80. In controlled long-term (48-week) extensions, which included both newly-treated and previously-treated patients, the incidence of consecutive elevations (>=3 ULN) in serum transaminases was 1.8% overall and 3.6% for patients treated with ezetimibe and simvastatin 10/80. These elevations in transaminases were generally asymptomatic, not associated with cholestasis, and returned to baseline after discontinuation of therapy or with continued treatment.In SHARP, 9,270 patients with chronic kidney disease were allocated to receive ezetimibe and simvastatin 10/20 mg daily (n=4,650), or placebo (n=4,620). During median follow-up period of 4.9 years, the incidence of consecutive elevations of transaminases (>3 ULN) was 0.7% for ezetimibe and simvastatin and 0.6% for placebo.It is recommended that liver function tests be performed before the initiation of treatment with ezetimibe and simvastatin, and thereafter when clinically indicated. There have been rare postmarketing reports of fatal and non-fatal hepatic failure in patients taking statins, including simvastatin. If serious liver injury with clinical symptoms and/or hyperbilirubinemia or jaundice occurs during treatment with ezetimibe and simvastatin, promptly interrupt therapy. If an alternate etiology is not found do not restart ezetimibe and simvastatin. Note that ALT may emanate from muscle, therefore ALT rising with CK may indicate myopathy [see Warnings and Precautions (5.1)] Ezetimibe and simvastatin should be used with caution in patients who consume substantial quantities of alcohol and/or have past history of liver disease. Active liver diseases or unexplained persistent transaminase elevations are contraindications to the use of ezetimibe and simvastatin.. 5.4 Endocrine Function. Increases in HbA1c and fasting serum glucose levels have been reported with HMG-CoA reductase inhibitors, including simvastatin.

ADVERSE REACTIONS SECTION.

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)] 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. 6.1) To report SUSPECTED ADVERSE REACTIONS, contact AvKARE at 1-855-361-3993 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.. Common (incidence >=2% and greater than placebo) adverse reactions in clinical trials: headache, increased ALT, myalgia, upper respiratory tract infection, and diarrhea. 6.1) 6.1 Clinical Trials Experience. Ezetimibe and simvastatinBecause clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.In the ezetimibe and simvastatin placebo-controlled clinical trials database of 1,420 patients (age range 20 to 83 years, 52% women, 87% Caucasians, 3% Blacks, 5% Hispanics, 3% Asians) with median treatment duration of 27 weeks, 5% of patients on ezetimibe and simvastatin 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 that led to treatment discontinuation and occurred at 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 has been evaluated for safety in more than 10,189 patients in clinical trials.Table summarizes the frequency of clinical adverse reactions reported in >=2% of patients treated with ezetimibe and simvastatin (n=1,420) and at an incidence greater than placebo, regardless of causality assessment, from four placebo-controlled trials.Table : Clinical Adverse Reactions Occurring in >=2% of Patients Treated with Ezetimibe and Simvastatin and at an Incidence Greater than Placebo, Regardless of CausalityBody System/Organ ClassAdverse ReactionPlacebo(%)n=371Ezetimibe10 mg(%)n=302Simvastatin (%)n=1,234Ezetimibe and simvastatin (%)n=1,420Body as whole general disordersHeadache5.46.05.95.8Gastrointestinal system disordersDiarrhea 2.25.03.72.8Infections and infestationsInfluenza 0.81.01.92.3Upper respiratory tract infection 2.75.05.03.6Musculoskeletal and connective tissue disordersMyalgia 2.42.32.63.6Pain in extremity 1.33.02.02.3 Includes two placebo-controlled combination studies in which the active ingredients equivalent to ezetimibe and simvastatin were co-administered and two placebo-controlled studies in which ezetimibe and simvastatin was administered. All doses. Study of Heart and Renal ProtectionIn SHARP, 9,270 patients were allocated to ezetimibe and simvastatin 10/20 mg daily (n=4,650) or placebo (n=4,620) for median follow-up period of 4.9 years. The proportion of patients who permanently discontinued study treatment as result of either an adverse event or abnormal safety blood result was 10.4% vs. 9.8% among patients allocated to ezetimibe and simvastatin and placebo, respectively. Comparing those allocated to ezetimibe and simvastatin vs. placebo, the incidence of myopathy (defined as unexplained muscle weakness or pain with serum CK >10 times ULN) was 0.2% vs. 0.1% and the incidence of rhabdomyolysis (defined as myopathy with CK >40 times ULN) was 0.09% vs. 0.02%, respectively. Consecutive elevations of transaminases (>3 ULN) occurred in 0.7% vs. 0.6%, respectively. Patients were asked about the occurrence of unexplained muscle pain or weakness at each study visit: 21.5% vs. 20.9% patients ever reported muscle symptoms in the ezetimibe and simvastatin and placebo groups, respectively. Cancer was diagnosed during the trial in 9.4% vs. 9.5% of patients assigned to ezetimibe and simvastatin and placebo, respectively.EzetimibeOther adverse reactions reported with ezetimibe in placebo-controlled studies, regardless of causality assessment: Musculoskeletal system disorders: arthralgia; Infections and infestations: sinusitis; Body as whole general disorders: fatigue. SimvastatinIn clinical trial in which 12,064 patients with history of myocardial infarction were treated with simvastatin (mean follow-up 6.7 years), the incidence of myopathy (defined as unexplained muscle weakness or pain with serum creatine kinase [CK] >10 times upper limit of normal [ULN]) in patients on 80 mg/day was approximately 0.9% compared with 0.02% for patients on 20 mg/day. The incidence of rhabdomyolysis (defined as myopathy with CK >40 times ULN) in patients on 80 mg/day was approximately 0.4% compared with 0% for patients on 20 mg/day. The incidence of myopathy, including rhabdomyolysis, was highest during the first year and then notably decreased during the subsequent years of treatment. In this trial, patients were carefully monitored and some interacting medicinal products were excluded.Other adverse reactions reported with simvastatin in placebo-controlled clinical studies, regardless of causality assessment: Cardiac disorders: atrial fibrillation; Ear and labyrinth disorders: vertigo; Gastrointestinal disorders: abdominal pain, constipation, dyspepsia, flatulence, gastritis; Skin and subcutaneous tissue disorders: eczema, rash; Endocrine disorders: diabetes mellitus; Infections and infestations: bronchitis, sinusitis, urinary tract infections; Body as whole general disorders: asthenia, edema/swelling; Psychiatric disorders: insomnia. Laboratory TestsMarked persistent increases of hepatic serum transaminases have been noted [see Warnings and Precautions (5.3)] Elevated alkaline phosphatase and -glutamyl transpeptidase have been reported. About 5% of patients taking simvastatin had elevations of CK levels of or more times the normal value on one or more occasions. This was attributable to the noncardiac fraction of CK [see Warnings and Precautions (5.1)] . Increased ALT (0.9%). Myalgia (0.6%). Increased AST (0.4%). Back pain (0.4%). 6.2 Postmarketing Experience. Because the below reactions are reported voluntarily from population of uncertain size, it is generally not possible to reliably estimate their frequency or establish causal relationship to drug exposure. The following adverse reactions have been reported in postmarketing experience for ezetimibe and simvastatin or ezetimibe or simvastatin: pruritus; alopecia; erythema multiforme; variety of skin changes (e.g., nodules, discoloration, dryness of skin/mucous membranes, changes to hair/nails); dizziness; muscle cramps; myalgia; arthralgia; pancreatitis; paresthesia; peripheral neuropathy; vomiting; nausea; anemia; erectile dysfunction; interstitial lung disease; myopathy/rhabdomyolysis [see Warnings and Precautions (5.1)] hepatitis/jaundice; fatal and non-fatal hepatic failure; depression; cholelithiasis; cholecystitis; thrombocytopenia; elevations in liver transaminases; elevated creatine phosphokinase. There have been rare reports of immune-mediated necrotizing myopathy associated with statin use [see Warnings and Precautions (5.1)] Hypersensitivity reactions, including anaphylaxis, angioedema, rash, and urticaria have been reported.In addition, an apparent hypersensitivity syndrome has been reported rarely that has included one or more of the following features: anaphylaxis, angioedema, lupus erythematous-like syndrome, polymyalgia rheumatica, dermatomyositis, vasculitis, purpura, thrombocytopenia, leukopenia, hemolytic anemia, positive ANA, ESR increase, eosinophilia, arthritis, arthralgia, urticaria, asthenia, photosensitivity, fever, chills, flushing, malaise, dyspnea, toxic epidermal necrolysis, erythema multiforme, including Stevens-Johnson syndrome.There have been rare postmarketing reports of cognitive impairment (e.g., memory loss, forgetfulness, amnesia, memory impairment, confusion) associated with statin use. These cognitive issues have been reported for all statins. The reports are generally nonserious, and reversible upon statin discontinuation, with variable times to symptom onset (1 day to years) and symptom resolution (median of weeks).

ANIMAL PHARMACOLOGY & OR TOXICOLOGY SECTION.

13.2 Animal Toxicology and/or Pharmacology. CNS ToxicityOptic nerve degeneration was seen in clinically normal dogs treated with simvastatin for 14 weeks at 180 mg/kg/day, dose that produced mean plasma drug levels about 12 times higher than the mean plasma drug level in humans taking 80 mg/day.A chemically similar drug in this class also produced optic nerve degeneration (Wallerian degeneration of retinogeniculate fibers) in clinically normal dogs in dose-dependent fashion starting at 60 mg/kg/day, dose that produced mean plasma drug levels about 30 times higher than the mean plasma drug level in humans taking the highest recommended dose (as measured by total enzyme inhibitory activity). This same drug also produced vestibulocochlear Wallerian-like degeneration and retinal ganglion cell chromatolysis in dogs treated for 14 weeks at 180 mg/kg/day, dose that resulted in mean plasma drug level similar to that seen with the 60 mg/kg/day dose.CNS vascular lesions, characterized by perivascular hemorrhage and edema, mononuclear cell infiltration of perivascular spaces, perivascular fibrin deposits and necrosis of small vessels, were seen in dogs treated with simvastatin at dose of 360 mg/kg/day, dose that produced mean plasma drug levels that were about 14 times higher than the mean plasma drug levels in humans taking 80 mg/day. Similar CNS vascular lesions have been observed with several other drugs of this class.There were cataracts in female rats after two years of treatment with 50 and 100 mg/kg/day (22 and 25 times the human AUC at 80 mg/day, respectively) and in dogs after three months at 90 mg/kg/day (19 times) and at two years at 50 mg/kg/day (5 times).EzetimibeThe hypocholesterolemic effect of ezetimibe was evaluated in cholesterol-fed Rhesus monkeys, dogs, rats, and mouse models of human cholesterol metabolism. Ezetimibe was found to have an ED 50 value of 0.5 mcg/kg/day for inhibiting the rise in plasma cholesterol levels in monkeys. The ED 50 values in dogs, rats, and mice were 7, 30, and 700 mcg/kg/day, respectively. These results are consistent with ezetimibe being potent cholesterol absorption inhibitor. In rat model, where the glucuronide metabolite of ezetimibe (ezetimibe-glucuronide) was administered intraduodenally, the metabolite was as potent as ezetimibe in inhibiting the absorption of cholesterol, suggesting that the glucuronide metabolite had activity similar to the parent drug.In 1-month studies in dogs given ezetimibe (0.03 mg/kg/day to 300 mg/kg/day), the concentration of cholesterol in gallbladder bile increased ~2- to 4-fold. However, dose of 300 mg/kg/day administered to dogs for one year did not result in gallstone formation or any other adverse hepatobiliary effects. In 14-day study in mice given ezetimibe (0.3 mg/kg/day to mg/kg/day) and fed low-fat or cholesterol-rich diet, the concentration of cholesterol in gallbladder bile was either unaffected or reduced to normal levels, respectively.A series of acute preclinical studies was performed to determine the selectivity of ezetimibe for inhibiting cholesterol absorption. Ezetimibe inhibited the absorption of 14C-cholesterol with no effect on the absorption of triglycerides, fatty acids, bile acids, progesterone, ethinyl estradiol, or the fat-soluble vitamins and D. In 4- to 12-week toxicity studies in mice, ezetimibe did not induce cytochrome P450 drug-metabolizing enzymes. In toxicity studies, pharmacokinetic interaction of ezetimibe with statins (parents or their active hydroxy acid metabolites) was seen in rats, dogs, and rabbits.

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. Ezetimibe and simvastatinNo animal carcinogenicity or fertility studies have been conducted with the combination of ezetimibe and simvastatin. The combination of ezetimibe with simvastatin did not show evidence of mutagenicity in vitro in microbial mutagenicity (Ames) test with Salmonella typhimurium and Escherichia coli with or without metabolic activation. No evidence of clastogenicity was observed in vitro in chromosomal aberration assay in human peripheral blood lymphocytes with ezetimibe and simvastatin with or without metabolic activation. There was no evidence of genotoxicity at doses up to 600 mg/kg with the combination of ezetimibe and simvastatin (1:1) in the in vivo mouse micronucleus test. EzetimibeA 104-week dietary carcinogenicity study with ezetimibe was conducted in rats at doses up to 1,500 mg/kg/day (males) and 500 mg/kg/day (females) (~20 times the human exposure at 10 mg daily based on AUC 0-24hr for total ezetimibe). 104-week dietary carcinogenicity study with ezetimibe was also conducted in mice at doses up to 500 mg/kg/day (>150 times the human exposure at 10 mg daily based on AUC 0-24hr for total ezetimibe). There were no statistically significant increases in tumor incidences in drug-treated rats or mice. No evidence of mutagenicity was observed in vitro in microbial mutagenicity (Ames) test with Salmonella typhimurium and Escherichia coli with or without metabolic activation. No evidence of clastogenicity was observed in vitro in chromosomal aberration assay in human peripheral blood lymphocytes with or without metabolic activation. In addition, there was no evidence of genotoxicity in the in vivo mouse micronucleus test. In oral (gavage) fertility studies of ezetimibe conducted in rats, there was no evidence of reproductive toxicity at doses up to 1,000 mg/kg/day in male or female rats (~7 times the human exposure at 10 mg daily based on AUC 0-24hr for total ezetimibe). SimvastatinIn 72-week carcinogenicity study, mice were administered daily doses of simvastatin of 25, 100, and 400 mg/kg body weight, which resulted in mean plasma drug levels approximately 1, 4, and times higher than the mean human plasma drug level, respectively, (as total inhibitory activity based on AUC) after an 80-mg oral dose. Liver carcinomas were significantly increased in high-dose females and mid- and high-dose males with maximum incidence of 90% in males. The incidence of adenomas of the liver was significantly increased in mid- and high-dose females. Drug treatment also significantly increased the incidence of lung adenomas in mid- and high-dose males and females. Adenomas of the Harderian gland (a gland of the eye of rodents) were significantly higher in high-dose mice than in controls. No evidence of tumorigenic effect was observed at 25 mg/kg/day.In separate 92-week carcinogenicity study in mice at doses up to 25 mg/kg/day, no evidence of tumorigenic effect was observed (mean plasma drug levels were times higher than humans given 80 mg simvastatin as measured by AUC).In two-year study in rats at 25 mg/kg/day, there was statistically significant increase in the incidence of thyroid follicular adenomas in female rats exposed to approximately 11 times higher levels of simvastatin than in humans given 80 mg simvastatin (as measured by AUC).A second two-year rat carcinogenicity study with doses of 50 and 100 mg/kg/day produced hepatocellular adenomas and carcinomas (in female rats at both doses and in males at 100 mg/kg/day). Thyroid follicular cell adenomas were increased in males and females at both doses; thyroid follicular cell carcinomas were increased in females at 100 mg/kg/day. The increased incidence of thyroid neoplasms appears to be consistent with findings from other statins. These treatment levels represented plasma drug levels (AUC) of approximately and 15 times (males) and 22 and 25 times (females) the mean human plasma drug exposure after an 80-mg daily dose.No evidence of mutagenicity was observed in microbial mutagenicity (Ames) test with or without rat or mouse liver metabolic activation. In addition, no evidence of damage to genetic material was noted in an in vitro alkaline elution assay using rat hepatocytes, V-79 mammalian cell forward mutation study, an in vitro chromosome aberration study in CHO cells, or an in vivo chromosomal aberration assay in mouse bone marrow. There was decreased fertility in male rats treated with simvastatin for 34 weeks at 25 mg/kg body weight (4 times the maximum human exposure level, based on AUC, in patients receiving 80 mg/day); however, this effect was not observed during subsequent fertility study in which simvastatin was administered at this same dose level to male rats for 11 weeks (the entire cycle of spermatogenesis including epididymal maturation). No microscopic changes were observed in the testes of rats from either study. At 180 mg/kg/day (which produces exposure levels 22 times higher than those in humans taking 80 mg/day based on surface area, mg/m 2), seminiferous tubule degeneration (necrosis and loss of spermatogenic epithelium) was observed. In dogs, there was drug-related testicular atrophy, decreased spermatogenesis, spermatocytic degeneration and giant cell formation at 10 mg/kg/day (approximately times the human exposure, based on AUC, at 80 mg/day). The clinical significance of these findings is unclear.

CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. Ezetimibe and simvastatinPlasma 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 reduces elevated total-C, LDL-C, Apo B, TG, and non-HDL-C, and increases HDL-C through dual inhibition of cholesterol absorption and synthesis.EzetimibeEzetimibe 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 (NPC1L1), which is involved in the intestinal uptake of cholesterol and phytosterols. In 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 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 decrease in the delivery of intestinal cholesterol to the liver. This causes 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)]. SimvastatinSimvastatin is prodrug and is hydrolyzed to its active -hydroxyacid form, simvastatin acid, after administration. Simvastatin is specific inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme (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.. 12.2 Pharmacodynamics. Clinical studies have demonstrated that elevated levels of total-C, LDL-C and Apo B, the major protein constituent of LDL, promote human atherosclerosis. In addition, decreased levels of HDL-C are associated with the development of atherosclerosis. Epidemiologic studies have established that cardiovascular morbidity and mortality vary directly with the level of total-C and LDL-C and inversely with the level of HDL-C. Like LDL, cholesterol-enriched triglyceride-rich lipoproteins, including VLDL, intermediate-density lipoproteins (IDL), and remnants, can also promote atherosclerosis. The independent effect of raising HDL-C or lowering TG on the risk of coronary and cardiovascular morbidity and mortality has not been determined.. 12.3 Pharmacokinetics. The results of bioequivalence study in healthy subjects demonstrated that the ezetimibe and simvastatin 10 mg/10 mg to 10 mg/80 mg combination tablets are bioequivalent to co-administration of corresponding doses of ezetimibe (ZETIA (R)) and simvastatin (ZOCOR (R)) as individual tablets. AbsorptionEzetimibeAfter oral administration, ezetimibe is absorbed and extensively conjugated to pharmacologically active phenolic glucuronide (ezetimibe-glucuronide).SimvastatinThe availability of the -hydroxyacid to the systemic circulation following an oral dose of simvastatin was found to be less than 5% of the dose, consistent with extensive hepatic first-pass extraction.Effect of Food on Oral AbsorptionEzetimibeConcomitant food administration (high-fat or non-fat meals) had no effect on the extent of absorption of ezetimibe when administered as 10-mg tablets. The max value of ezetimibe was increased by 38% with consumption of high-fat meals. SimvastatinRelative to the fasting state, the plasma profiles of both active and total inhibitors of HMG-CoA reductase were not affected when simvastatin was administered immediately before an American Heart Association recommended low-fat meal.DistributionEzetimibeEzetimibe and ezetimibe-glucuronide are highly bound (>90%) to human plasma proteins.SimvastatinBoth simvastatin and its -hydroxyacid metabolite are highly bound (approximately 95%) to human plasma proteins. When radiolabeled simvastatin was administered to rats, simvastatin-derived radioactivity crossed the blood-brain barrier.Metabolism and ExcretionEzetimibeEzetimibe is primarily metabolized in the small intestine and liver via glucuronide conjugation with subsequent biliary and renal excretion. Minimal oxidative metabolism has been observed in all species evaluated.In humans, ezetimibe is rapidly metabolized to ezetimibe-glucuronide. Ezetimibe and ezetimibe-glucuronide are the major drug-derived compounds detected in plasma, constituting approximately 10 to 20% and 80 to 90% of the total drug in plasma, respectively. Both ezetimibe and ezetimibe-glucuronide are eliminated from plasma with half-life of approximately 22 hours for both ezetimibe and ezetimibe-glucuronide. Plasma concentration-time profiles exhibit multiple peaks, suggesting enterohepatic recycling.Following oral administration of 14C-ezetimibe (20 mg) to human subjects, total ezetimibe (ezetimibe ezetimibe-glucuronide) accounted for approximately 93% of the total radioactivity in plasma. After 48 hours, there were no detectable levels of radioactivity in the plasma. Approximately 78% and 11% of the administered radioactivity were recovered in the feces and urine, respectively, over 10-day collection period. Ezetimibe was the major component in feces and accounted for 69% of the administered dose, while ezetimibe-glucuronide was the major component in urine and accounted for 9% of the administered dose.SimvastatinSimvastatin is lactone that is readily hydrolyzed in vivo to the corresponding -hydroxyacid, potent inhibitor of HMG-CoA reductase. Inhibition of HMG-CoA reductase is basis for an assay in pharmacokinetic studies of the -hydroxyacid metabolites (active inhibitors) and, following base hydrolysis, active plus latent inhibitors (total inhibitors) in plasma following administration of simvastatin. The major active metabolites of simvastatin present in human plasma are the -hydroxyacid of simvastatin and its 6-hydroxy, 6-hydroxymethyl, and 6-exomethylene derivatives. Following an oral dose of 14C-labeled simvastatin in man, 13% of the dose was excreted in urine and 60% in feces. Plasma concentrations of total radioactivity (simvastatin plus 14C-metabolites) peaked at hours and declined rapidly to about 10% of peak by 12 hours postdose. Specific PopulationsGeriatric PatientsEzetimibeIn multiple-dose study with ezetimibe given 10 mg once daily for 10 days, plasma concentrations for total ezetimibe were about 2-fold higher in older (>=65 years) healthy subjects compared to younger subjects.SimvastatinIn study including 16 elderly patients between 70 and 78 years of age who received simvastatin 40 mg/day, the mean plasma level of HMG-CoA reductase inhibitory activity was increased approximately 45% compared with 18 patients between 18 to 30 years of age.Pediatric Patients: [see Use in Specific Populations (8.4)]. GenderEzetimibeIn multiple-dose study with ezetimibe given 10 mg once daily for 10 days, plasma concentrations for total ezetimibe were slightly higher (<20%) in women than in men.RaceEzetimibeBased on meta-analysis of multiple-dose pharmacokinetic studies, there were no pharmacokinetic differences between Black and Caucasian subjects. Studies in Asian subjects indicated that the pharmacokinetics of ezetimibe was similar to those seen in Caucasian subjects.Hepatic ImpairmentEzetimibeAfter single 10-mg dose of ezetimibe, the mean exposure (based on area under the curve [AUC]) to total ezetimibe was increased approximately 1.7-fold in patients with mild hepatic impairment (Child-Pugh score to 6), compared to healthy subjects. The mean AUC values for total ezetimibe and ezetimibe increased approximately 3- to 4-fold and 5- to 6-fold, respectively, in patients with moderate (Child-Pugh score to 9) or severe hepatic impairment (Child-Pugh score 10 to 15). In 14-day, multiple-dose study (10 mg daily) in patients with moderate hepatic impairment, the mean AUC for total ezetimibe and ezetimibe increased approximately 4-fold compared to healthy subjects.Renal ImpairmentEzetimibeAfter single 10-mg dose of ezetimibe in patients with severe renal disease (n=8; mean CrCl <=30 mL/min/1.73 2), the mean AUC for total ezetimibe and ezetimibe increased approximately 1.5-fold, compared to healthy subjects (n=9). SimvastatinPharmacokinetic studies with another statin having similar principal route of elimination to that of simvastatin have suggested that for given dose level higher systemic exposure may be achieved in patients with severe renal impairment (as measured by creatinine clearance).Drug Interactions [see also Drug Interactions (7)].No clinically significant pharmacokinetic interaction was seen when ezetimibe was co-administered with simvastatin. No specific pharmacokinetic drug interaction studies with ezetimibe and simvastatin have been conducted other than the following study with NIASPAN (Niacin extended-release tablets).Niacin: The effect of ezetimibe and simvastatin (10/20 mg daily for days) on the pharmacokinetics of NIASPAN extended-release tablets (1,000 mg for days and 2,000 mg for days following low-fat breakfast) was studied in healthy subjects. The mean max and AUC of niacin increased 9% and 22%, respectively. The mean max and AUC of nicotinuric acid increased 10% and 19%, respectively (N=13). In the same study, the effect of NIASPAN on the pharmacokinetics of ezetimibe and simvastatin was evaluated (N=15). While concomitant NIASPAN decreased the mean max of total ezetimibe (1%), and simvastatin (2%), it increased the mean max of simvastatin acid (18%). In addition, concomitant NIASPAN increased the mean AUC of total ezetimibe (26%), simvastatin (20%), and simvastatin acid (35%). Cases of myopathy/rhabdomyolysis have been observed with simvastatin co-administered with lipid-modifying doses (>=1 g/day niacin) of niacin-containing products [see Warnings and Precautions (5.1) and Drug Interactions (7.4)] Cytochrome P450: Ezetimibe had no significant effect on series of probe drugs (caffeine, dextromethorphan, tolbutamide, and IV midazolam) known to be metabolized by cytochrome P450 (1A2, 2D6, 2C8/9 and 3A4) in cocktail study of twelve healthy adult males. This indicates that ezetimibe is neither an inhibitor nor an inducer of these cytochrome P450 isozymes, and it is unlikely that ezetimibe will affect the metabolism of drugs that are metabolized by these enzymes. In study of 12 healthy volunteers, simvastatin at the 80-mg dose had no effect on the metabolism of the probe cytochrome P450 isoform 3A4 (CYP3A4) substrates midazolam and erythromycin. This indicates that simvastatin is not an inhibitor of CYP3A4 and, therefore, is not expected to affect the plasma levels of other drugs metabolized by CYP3A4.Simvastatin acid is substrate of the transport protein OATP1B1. Concomitant administration of medicinal products that are inhibitors of the transport protein OATP1B1 may lead to increased plasma concentrations of simvastatin acid and an increased risk of myopathy. For example, cyclosporine has been shown to increase the AUC of statins; although the mechanism is not fully understood, the increase in AUC for simvastatin acid is presumably due, in part, to inhibition of CYP3A4 and/or OATP1B1.Simvastatin is substrate for CYP3A4. Inhibitors of CYP3A4 can raise the plasma levels of HMG-CoA reductase inhibitory activity and increase the risk of myopathy [see Warnings and Precautions (5.1); Drug Interactions (7.1)] EzetimibeTable 4: Effect of Co-administered Drugs on Total EzetimibeCo-administered Drug and Dosing RegimenTotal Ezetimibe Change in AUCChange in max Cyclosporine-stable dose required (75 mg to 150 mg BID) +, 240%290%Fenofibrate, 200 mg QD, 14 days 48%64%Gemfibrozil, 600 mg BID, days 64%91%Cholestyramine, g BID, 14 days 55%4%Aluminum magnesium hydroxide combination antacid, single dose 4%30%Cimetidine, 400 mg BID, days6%22%Glipizide, 10 mg, single dose4%8%StatinsLovastatin 20 mg QD, days9%3%Pravastatin 20 mg QD, 14 days7%23%Atorvastatin 10 mg QD, 14 days2%12%Rosuvastatin 10 mg QD, 14 days13%18%Fluvastatin 20 mg QD, 14 days19%7% Based on 10 mg-dose of ezetimibe.+ Post-renal transplant patients with mild impaired or normal renal function.

CLINICAL STUDIES SECTION.

14 CLINICAL STUDIES. 14.1 Primary Hyperlipidemia. Ezetimibe and simvastatinEzetimibe and simvastatin reduces total-C, LDL-C, Apo B, TG, and non-HDL-C, and increases HDL-C in patients with hyperlipidemia. Maximal to near maximal response is generally achieved within weeks and maintained during chronic therapy.Ezetimibe and simvastatin is effective in men and women with hyperlipidemia. Experience in non-Caucasians is limited and does not permit precise estimate of the magnitude of the effects of ezetimibe and simvastatin.Five multicenter, double-blind studies conducted with either ezetimibe and simvastatin or co-administered ezetimibe and simvastatin equivalent to ezetimibe and simvastatin in patients with primary hyperlipidemia are reported: two were comparisons with simvastatin, two were comparisons with atorvastatin, and one was comparison with rosuvastatin.In multicenter, double-blind, placebo-controlled, 12-week trial, 1,528 hyperlipidemic patients were randomized to one of ten treatment groups: placebo, ezetimibe (10 mg), simvastatin (10 mg, 20 mg, 40 mg, or 80 mg), or ezetimibe and simvastatin (10/10, 10/20, 10/40, or 10/80).When patients receiving ezetimibe and simvastatin were compared to those receiving all doses of simvastatin, ezetimibe and simvastatin significantly lowered total-C, LDL-C, Apo B, TG, and non-HDL-C. The effects of ezetimibe and simvastatin on HDL-C were similar to the effects seen with simvastatin. Further analysis showed ezetimibe and simvastatin significantly increased HDL-C compared with placebo (see Table 7). The lipid response to ezetimibe and simvastatin was similar in patients with TG levels greater than or less than 200 mg/dL.Table 7: Response to Ezetimibe and simvastatin in Patients with Primary Hyperlipidemia (Mean Change from Untreated Baseline +) Treatment(Daily Dose)NTotal-CLDL-CApo BHDL-CTG Non-HDL-CPooled data (All ezetimibe and simvastatin doses) 609-38-53-42+7-24-49Pooled data (All simvastatindoses) 622-28-39-32+7-21-36Ezetimibe 10 mg149-13-19-15+5-11-18Placebo148-1-200-2-2Ezetimibe and simvastatin by dose10/10152-31-45-35+8-23-4110/20156-36-52-41+10-24-4710/40147-39-55-44+6-23-5110/80154-43-60-49+6-31-56Simvastatin by dose10 mg158-23-33-26+5-17-3020 mg150-24-34-28+7-18-3240 mg156-29-41-33+8-21-3880 mg158-35-49-39+7-27-45 For triglycerides, median change from baseline. Baseline on no lipid-lowering drug. Ezetimibe and simvastatin doses pooled (10/10 to 10/80) significantly reduced total-C, LDL-C, Apo B, TG, and non-HDL-C compared to simvastatin and significantly increased HDL-C compared to placebo. In multicenter, double-blind, controlled, 23-week study, 710 patients with known CHD or CHD risk equivalents, as defined by the NCEP ATP III guidelines, and an LDL-C >=130 mg/dL were randomized to one of four treatment groups: co-administered ezetimibe and simvastatin equivalent to ezetimibe and simvastatin (10/10, 10/20, and 10/40) or simvastatin 20 mg. Patients not reaching an LDL-C <100 mg/dL had their simvastatin dose titrated at 6-week intervals to maximal dose of 80 mg.At Week 5, the LDL-C reductions with ezetimibe and simvastatin 10/10, 10/20, or 10/40 were significantly larger than with simvastatin 20 mg (see Table 8).Table 8: Response to Ezetimibe and simvastatin after Weeks in Patients with CHD or CHD Risk Equivalents and an LDL-C >=130 mg/dLSimvastatin20 mgEzetimibe and simvastatin10/10Ezetimibe and simvastatin 10/20Ezetimibe and simvastatin 10/40N25325110997Mean baseline LDL-C174165167171Percent change LDL-C-38-47-53-59In multicenter, double-blind, 6-week study, 1,902 patients with primary hyperlipidemia, who had not met their NCEP ATP III target LDL-C goal, were randomized to one of eight treatment groups: ezetimibe and simvastatin (10/10, 10/20, 10/40, or 10/80) or atorvastatin (10 mg, 20 mg, 40 mg, or 80 mg).Across the dosage range, when patients receiving ezetimibe and simvastatin were compared to those receiving milligram-equivalent statin doses of atorvastatin, ezetimibe and simvastatin lowered total-C, LDL-C, Apo B, and non-HDL-C significantly more than atorvastatin. Only the 10/40 mg and 10/80 mg ezetimibe and simvastatin doses increased HDL-C significantly more than the corresponding milligram-equivalent statin dose of atorvastatin. The effects of ezetimibe and simvastatin on TG were similar to the effects seen with atorvastatin (see Table 9).Table 9: Response to Ezetimibe and simvastatin and Atorvastatin in Patients with Primary Hyperlipidemia (Mean Change from Untreated Baseline +) Treatment(Daily Dose)NTotal-C LDL-C Apo HDL-CTGNon-HDL-C Ezetimibe and simvastatin by dose10/10230-34 -47 -37 +8-26-43 10/20233-37 -51 -40 +7-25-46 10/40236-41 -57 -46 +9 -27-52 10/80224-43 -59 -48 +8 -31-54 Atorvastatin by dose10 mg235-27-36-31+7-21-3420 mg230-32-44-37+5-25-4140 mg232-36-48-40+4-24-4580 mg230-40-53-44+1-32-50 For triglycerides, median change from baseline.

In multicenter, double-blind, 24-week, forced-titration study, 788 patients with primary hyperlipidemia, who had not met their NCEP ATP III target LDL-C goal, were randomized to receive co-administered ezetimibe and simvastatin equivalent to ezetimibe and simvastatin (10/10 and 10/20) or atorvastatin 10 mg. For all three treatment groups, the dose of the statin was titrated at 6-week intervals to 80 mg. At each pre-specified dose comparison, ezetimibe and simvastatin lowered LDL-C to greater degree than atorvastatin (see Table 10).Table 10: Response to Ezetimibe and simvastatin and Atorvastatin in Patients with Primary Hyperlipidemia (Mean Change from Untreated Baseline +) TreatmentNTotal-CLDL-CApo BHDL-CTG Non-HDL-CWeek 6Atorvastatin 10 mg 262-28-37-32+5-23-35Ezetimibe and simvastatin 10/10 263-34 -46 -38 +8 -26-43 Ezetimibe and simvastatin 10/20 263-36 -50 -41 +10 -25-46 Week 12Atorvastatin 20 mg246-33-44-38+7-28-42Ezetimibe and simvastatin 10/20250-37 -50 -41 +9-28-46 Ezetimibe and simvastatin 10/40252-39 -54 -45 +12 -31-50 Week 18Atorvastatin 40 mg237-37-49-42+8-31-47Ezetimibe and simvastatin 10/40 TH 482-40 -56 -45 +11 -32-52 Week 24Atorvastatin 80 mg228-40-53-45+6-35-50Ezetimibe and simvastatin 10/80 TH 459-43 -59 -49 +12 -35-55 For triglycerides, median change from baseline.

In multicenter, double-blind, 6-week study, 2,959 patients with primary hyperlipidemia, who had not met their NCEP ATP III target LDL-C goal, were randomized to one of six treatment groups: ezetimibe and simvastatin (10/20, 10/40, or 10/80) or rosuvastatin (10 mg, 20 mg, or 40 mg).The effects of ezetimibe and simvastatin and rosuvastatin on total-C, LDL-C, Apo B, TG, non-HDL-C and HDL-C are shown in Table 11.Table 11: Response to Ezetimibe and simvastatin and Rosuvastatin in Patients with Primary Hyperlipidemia (Mean Change from Untreated Baseline +) Treatment(Daily Dose)NTotal-C LDL-C Apo HDL-CTG Non-HDL-C Ezetimibe and simvastatin by dose10/20476-37 -52 -42 +7-23 -47 10/40477-39 -55 -44 +8-27-50 10/80474-44 -61 -50 +8-30 -56 Rosuvastatin by dose10 mg475-32-46-37+7-20-4220 mg478-37-52-43+8-26-4840 mg475-41-57-47+8-28-52 For triglycerides, median change from baseline. Baseline on no lipid-lowering drug. Ezetimibe and simvastatin doses pooled (10/20 to 10/80) provided significantly greater reductions in total-C, LDL-C, Apo B, and non-HDL-C compared to rosuvastatin doses pooled (10 mg to 40 mg). p<0.05 vs. rosuvastatin 10 mg. p<0.05 vs. rosuvastatin 20 mg. p<0.05 vs. rosuvastatin 40 mg. In multicenter, double-blind, 24-week trial, 214 patients with type diabetes mellitus treated with thiazolidinediones (rosiglitazone or pioglitazone) for minimum of months and simvastatin 20 mg for minimum of weeks were randomized to receive either simvastatin 40 mg or the co-administered active ingredients equivalent to ezetimibe and simvastatin 10/20. The median LDL-C and HbA1c levels at baseline were 89 mg/dL and 7.1%, respectively.Ezetimibe and simvastatin 10/20 was significantly more effective than doubling the dose of simvastatin to 40 mg. The median percent changes from baseline for ezetimibe and simvastatin vs. simvastatin were: LDL-C -25% and -5%; total-C -16% and -5%; Apo -19% and -5%; and non-HDL-C -23% and -5%. Results for HDL-C and TG between the two treatment groups were not significantly different.EzetimibeIn two multicenter, double-blind, placebo-controlled, 12-week studies in 1,719 patients with primary hyperlipidemia, ezetimibe significantly lowered total-C (-13%), LDL-C (-19%), Apo (-14%), and TG (-8%), and increased HDL-C (+3%) compared to placebo. Reduction in LDL-C was consistent across age, sex, and baseline LDL-C.SimvastatinIn two large, placebo-controlled clinical trials, the Scandinavian Simvastatin Survival Study (N=4,444 patients) and the Heart Protection Study (N=20,536 patients), the effects of treatment with simvastatin were assessed in patients at high risk of coronary events because of existing coronary heart disease, diabetes, peripheral vessel disease, history of stroke or other cerebrovascular disease. Simvastatin was proven to reduce: the risk of total mortality by reducing CHD deaths; the risk of non-fatal myocardial infarction and stroke; and the need for coronary and non-coronary revascularization procedures. No incremental benefit of ezetimibe and simvastatin on cardiovascular morbidity and mortality over and above that demonstrated for simvastatin has been established.. 14.2 Homozygous Familial Hypercholesterolemia (HoFH). double-blind, randomized, 12-week study was performed in patients with clinical and/or genotypic diagnosis of HoFH. Data were analyzed from subgroup of patients (n=14) receiving simvastatin 40 mg at baseline. Increasing the dose of simvastatin from 40 to 80 mg (n=5) produced reduction of LDL-C of 13% from baseline on simvastatin 40 mg. Co-administered ezetimibe and simvastatin equivalent to ezetimibe and simvastatin (10/40 and 10/80 pooled, n=9), produced reduction of LDL-C of 23% from baseline on simvastatin 40 mg. In those patients co-administered ezetimibe and simvastatin equivalent to ezetimibe and simvastatin (10/80, n=5), reduction of LDL-C of 29% from baseline on simvastatin 40 mg was produced.. 14.3 Chronic Kidney Disease (CKD). The Study of Heart and Renal Protection (SHARP) was multinational, randomized, placebo-controlled, double-blind trial that investigated the effect of ezetimibe and simvastatin on the time to first major vascular event (MVE) among 9,438 patients with moderate to severe chronic kidney disease (approximately one-third on dialysis at baseline) who did not have history of myocardial infarction or coronary revascularization. An MVE was defined as nonfatal MI, cardiac death, stroke, or any revascularization procedure. Patients were allocated to treatment using method that took into account the distribution of important baseline characteristics of patients already enrolled and minimized the imbalance of those characteristics across the groups.For the first year, 9,438 patients were allocated 4:4:1, to ezetimibe and simvastatin 10/20, placebo, or simvastatin 20 mg daily, respectively. The 1-year simvastatin arm enabled the comparison of ezetimibe and simvastatin to simvastatin with regard to safety and effect on lipid levels. At year the simvastatin-only arm was re-allocated 1:1 to ezetimibe and simvastatin 10/20 or placebo. total of 9,270 patients were ever allocated to ezetimibe and simvastatin 10/20 (n=4,650) or placebo (n=4,620) during the trial. The median follow-up duration was 4.9 years. Patients had mean age of 61 years; 63% were male, 72% were Caucasian, and 23% were diabetic; and, for those not on dialysis at baseline, the median serum creatinine was 2.5 mg/dL and the median estimated glomerular filtration rate (eGFR) was 25.6 mL/min/1.73 2, with 94% of patients having an eGFR 45 mL/min/1.73m 2. Eligibility did not depend on lipid levels. Mean LDL-C at baseline was 108 mg/dL. At year, the mean LDL-C was 26% lower in the simvastatin arm and 38% lower in the ezetimibe and simvastatin arm relative to placebo. At the midpoint of the study (2.5 years), the mean LDL-C was 32% lower for ezetimibe and simvastatin relative to placebo. Patients no longer taking study medication were included in all lipid measurements. In the primary intent-to-treat analysis, 639 (15.2%) of 4,193 patients initially allocated to ezetimibe and simvastatin and 749 (17.9%) of 4,191 patients initially allocated to placebo experienced an MVE. This corresponded to relative risk reduction of 16% (p=0.001) (see Figure 1). Similarly, 526 (11.3%) of 4,650 patients ever allocated to ezetimibe and simvastatin and 619 (13.4%) of 4,620 patients ever allocated to placebo experienced major atherosclerotic event (MAE; subset of the MVE composite that excluded non-coronary cardiac deaths and hemorrhagic stroke), corresponding to relative risk reduction of 17% (p=0.002). The trial demonstrated that treatment with ezetimibe and simvastatin 10/20 mg versus placebo reduced the risk for MVE and MAE in this CKD population. The study design precluded drawing conclusions regarding the independent contribution of either ezetimibe or simvastatin to the observed effect.The treatment effect of ezetimibe and simvastatin on MVE was attenuated among patients on dialysis at baseline compared with those not on dialysis at baseline. Among 3,023 patients on dialysis at baseline, ezetimibe and simvastatin reduced the risk of MVE by 6% (RR 0.94: 95% CI 0.80 to 1.09) compared with 22% (RR 0.78: 95% CI 0.69 to 0.89) among 6,247 patients not on dialysis at baseline (interaction P=0.08). Figure 1: Effect of Ezetimibe and Simvastatin on the Primary Endpoint of Risk of Major Vascular EventsThe individual components of MVE in all patients ever allocated to ezetimibe and simvastatin or placebo are presented in Table 12.Table 12: Number of First Events for Each Component of the Major Vascular Event Composite Endpoint in SHARP OutcomeEzetimibe and simvastatin 10/20(N=4,650)Placebo(N=4,620)Risk Ratio(95% CI)P-valueMajor Vascular Events701 (15.1%)814 (17.6%)0.85 (0.77 to 0.94)0.001Nonfatal MI134 (2.9%)159 (3.4%)0.84 (0.66 to 1.05)0.12Cardiac Death253 (5.4%)272 (5.9%)0.93 (0.78 to 1.10)0.38Any Stroke171 (3.7%)210 (4.5%)0.81 (0.66 to 0.99)0.038Non-hemorrhagic Stroke131 (2.8%)174 (3.8%)0.75 (0.60 to 0.94)0.011Hemorrhagic Stroke 45 (1.0%)37 (0.8%)1.21 (0.78 to 1.86)0.40Any Revascularization284 (6.1%)352 (7.6%)0.79 (0.68 to 0.93)0.004 Intention-to-treat analysis on all SHARP patients ever allocated to ezetimibe and simvastatin or placebo.

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 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 bile acid sequestrant. 2.3, 7.5) 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 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 bile acid sequestrant. 2.3, 7.5) 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 single daily dose in the evening, with or without food. Patients who require 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 2). After initiation or titration of ezetimibe and simvastatin tablets, lipid levels may be analyzed after 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 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 Co-administration with Other Drugs.

Dosing of ezetimibe and simvastatin tablets should occur either greater than or equal to hours before or greater than or equal to hours after administration of bile acid sequestrant [see Drug Interactions (7.5)] . 2.4 Patients with Homozygous Familial Hypercholesterolemia. The recommended dosage for patients with homozygous familial hypercholesterolemia is ezetimibe and simvastatin tablets 10/40 mg/day in the evening [see Dosage and Administration, Restricted Dosing for 10/80 mg (2.2)] Ezetimibe and simvastatin tablets should be used as an adjunct to other lipid-lowering treatments (e.g., LDL apheresis) in these patients or if such treatments are unavailable. Simvastatin exposure is approximately doubled with concomitant use of lomitapide; therefore, the dose of ezetimibe and simvastatin tablets should be reduced by 50% if initiating lomitapide. Ezetimibe and simvastatin tablets dosage should not exceed 10/20 mg/day (or 10/40 mg/day for patients who have previously taken simvastatin 80 mg/day chronically, e.g., for 12 months or more, without evidence of muscle toxicity) while taking lomitapide.. 2.5 Patients with Renal Impairment/Chronic Kidney Disease. In patients with mild renal impairment (estimated GFR greater than or equal to 60 mL/min/1.73 2), no dosage adjustment is necessary. In patients with chronic kidney disease and estimated glomerular filtration rate less than 60 mL/min/1.73 2, the dose of ezetimibe and simvastatin tablets is 10/20 mg/day in the evening. In such patients, higher doses should be used with caution and close monitoring [see Warnings and Precautions (5.1); Clinical Pharmacology (12.3)] . 2.6 Geriatric Patients. No dosage adjustment is necessary in geriatric patients [see Clinical Pharmacology (12.3)].

DRUG INTERACTIONS SECTION.

7 DRUG INTERACTIONS. [See Clinical Pharmacology (12.3)].Ezetimibe and simvastatin. Drug Interactions Associated with Increased Risk of Myopathy/Rhabdomyolysis 2.3, 2.4, 4, 5.1, 7.1, 7.2, 7.3, 7.8, 12.3) Interacting AgentsPrescribing Recommendations Strong CYP3A4 Inhibitors,(e.g., itraconazole, ketoconazole, posaconazole, voriconazole, erythromycin, clarithromycin, telithromycin, HIV protease inhibitors, boceprevir, telaprevir, nefazodone, cobicistat-containing products), gemfibrozil, cyclosporine, danazolContraindicated with ezetimibe and simvastatinNiacin (>=1 g/day)For Chinese patients, not recommended with ezetimibe and simvastatinVerapamil, diltiazem, dronedaroneDo not exceed 10/10 mgezetimibe and simvastatin dailyAmiodarone, amlodipine, ranolazineDo not exceed 10/20 mgezetimibe and simvastatin dailyLomitapideFor patients with HoFH, do not exceed 10/20 mg ezetimibe and simvastatin daily DaptomycinTemporarily suspend ezetimibe and simvastatinGrapefruit juiceAvoid grapefruit juice For patients with HoFH who have been taking 80 mg simvastatin chronically (e.g., for 12 months or more) without evidence of muscle toxicity, do not exceed 10/40 mg ezetimibe and simvastatin when taking lomitapide. Coumarin anticoagulants: simvastatin prolongs INR. Achieve stable INR prior to starting ezetimibe and simvastatin. Monitor INR frequently until stable upon initiation or alteration of ezetimibe and simvastatin therapy. 7.8) Cholestyramine: Combination decreases exposure of ezetimibe. 2.3, 7.5) Other Lipid-lowering Medications: Use with fenofibrates increases the risk of adverse skeletal muscle effects. Caution should be used when prescribing with ezetimibe and simvastatin. 5.1, 7.2) Fenofibrates: Combination increases exposure of ezetimibe. If cholelithiasis is suspected in patient receiving ezetimibe and fenofibrate, gallbladder studies are indicated and alternative lipid-lowering therapy should be considered. 7.2, 7.7, 12.3) Coumarin anticoagulants: simvastatin prolongs INR. Achieve stable INR prior to starting ezetimibe and simvastatin. Monitor INR frequently until stable upon initiation or alteration of ezetimibe and simvastatin therapy. 7.8) Cholestyramine: Combination decreases exposure of ezetimibe. 2.3, 7.5) Other Lipid-lowering Medications: Use with fenofibrates increases the risk of adverse skeletal muscle effects. Caution should be used when prescribing with ezetimibe and simvastatin. 5.1, 7.2) Fenofibrates: Combination increases exposure of ezetimibe. If cholelithiasis is suspected in patient receiving ezetimibe and fenofibrate, gallbladder studies are indicated and alternative lipid-lowering therapy should be considered. 7.2, 7.7, 12.3) 7.1 Strong CYP3A4 Inhibitors, Cyclosporine, or Danazol. Strong CYP3A4 inhibitors: The risk of myopathy is increased by reducing the elimination of the simvastatin component of ezetimibe and simvastatin. Hence when ezetimibe and simvastatin is used with an inhibitor of CYP3A4 (e.g., as listed below), elevated plasma levels of HMG-CoA reductase inhibitory activity increases the risk of myopathy and rhabdomyolysis, particularly with higher doses of ezetimibe and simvastatin [see Warnings and Precautions (5.1) and Clinical Pharmacology (12.3)]. Concomitant use of drugs labeled as having strong inhibitory effect on CYP3A4 is contraindicated [see Contraindications (4)]. If treatment with itraconazole, ketoconazole, posaconazole, voriconazole, erythromycin, clarithromycin or telithromycin is unavoidable, therapy with ezetimibe and simvastatin must be suspended during the course of treatment. Cyclosporine or Danazol: The risk of myopathy, including rhabdomyolysis is increased by concomitant administration of cyclosporine or danazol. Therefore, concomitant use of these drugs is contraindicated [see Contraindications (4), Warnings and Precautions (5.1) and Clinical Pharmacology (12.3)]. 7.2 Lipid-Lowering Drugs That Can Cause Myopathy When Given Alone. Gemfibrozil: Contraindicated with ezetimibe and simvastatin [see Contraindications (4) and Warnings and Precautions (5.1)] Fenofibrates (e.g., fenofibrate and fenofibric acid): Caution should be used when prescribing with ezetimibe and simvastatin [see Warnings and Precautions (5.1) and Drug Interactions (7.7)] . 7.3 Amiodarone, Dronedarone, Ranolazine, or Calcium Channel Blockers. The risk of myopathy, including rhabdomyolysis, is increased by concomitant administration of amiodarone, dronedarone, ranolazine, or calcium channel blockers such as verapamil, diltiazem or amlodipine [see Dosage and Administration (2.3) and Warnings and Precautions (5.1) and Table in Clinical Pharmacology (12.3)]. 7.4 Niacin. Cases of myopathy/rhabdomyolysis have been observed with simvastatin co-administered with lipid-modifying doses (>=1 g/day niacin) of niacin-containing products. The risk of myopathy is greater in Chinese patients. In clinical trial (median follow-up 3.9 years) involving patients at high risk of cardiovascular disease and with well-controlled LDL-C levels on simvastatin 40 mg/day with or without ezetimibe 10 mg/day, there was no incremental benefit on cardiovascular outcomes with the addition of lipid-modifying doses (>=1 g/day) of niacin. Co-administration of ezetimibe and simvastatin with lipid-modifying doses (>=1g/day) of niacin is not recommended in Chinese patients. It is unknown if this risk applies to other Asian patients [see Warnings and Precautions (5.1) and Use in Specific Populations (8.8)] . 7.5 Cholestyramine. Concomitant cholestyramine administration decreased the mean AUC of total ezetimibe approximately 55%. The incremental LDL-C reduction due to adding ezetimibe and simvastatin to cholestyramine may be reduced by this interaction.. 7.6 Digoxin. In one study, concomitant administration of digoxin with simvastatin resulted in slight elevation in plasma digoxin concentrations. Patients taking digoxin should be monitored appropriately when ezetimibe and simvastatin is initiated.. 7.7 Fenofibrates (e.g., fenofibrate and fenofibric acid). The safety and effectiveness of ezetimibe and simvastatin administered with fibrates have not been established. Because it is known that the risk of myopathy during treatment with HMG-CoA reductase inhibitors is increased with concurrent administration of fenofibrates, ezetimibe and simvastatin should be administered with caution when used concomitantly with fenofibrate [see Warnings and Precautions (5.1)] Fenofibrates may increase cholesterol excretion into the bile, leading to cholelithiasis. In preclinical study in dogs, ezetimibe increased cholesterol in the gallbladder bile [see Animal Toxicology and/or Pharmacology (13.2) ]. If cholelithiasis is suspected in patient receiving ezetimibe and simvastatin and fenofibrate, gallbladder studies are indicated and alternative lipid-lowering therapy should be considered [see the product labeling for fenofibrate and fenofibric acid]. 7.8 Coumarin Anticoagulants. Simvastatin 20 mg/day to 40 mg/day modestly potentiated the effect of coumarin anticoagulants: the prothrombin time, reported as International Normalized Ratio (INR), increased from baseline of 1.7 to 1.8 and from 2.6 to 3.4 in normal volunteer study and in hypercholesterolemic patient study, respectively. With other statins, clinically evident bleeding and/or increased prothrombin time has been reported in few patients taking coumarin anticoagulants concomitantly. In such patients, prothrombin time should be determined before starting ezetimibe and simvastatin and frequently enough during early therapy to ensure that no significant alteration of prothrombin time occurs. Once stable prothrombin time has been documented, prothrombin times can be monitored at the intervals usually recommended for patients on coumarin anticoagulants. If the dose of ezetimibe and simvastatin is changed or discontinued, the same procedure should be repeated. Simvastatin therapy has not been associated with bleeding or with changes in prothrombin time in patients not taking anticoagulants.Concomitant administration of ezetimibe (10 mg once daily) had no significant effect on bioavailability of warfarin and prothrombin time in study of twelve healthy adult males. There have been postmarketing reports of increased INR in patients who had ezetimibe added to warfarin. Most of these patients were also on other medications.The effect of ezetimibe and simvastatin on the prothrombin time has not been studied.. 7.9 Colchicine. Cases of myopathy, including rhabdomyolysis, have been reported with simvastatin co-administered with colchicine, and caution should be exercised when prescribing ezetimibe and simvastatin with colchicine.. 7.10 Daptomycin. Cases of rhabdomyolysis have been reported with ezetimibe and simvastatin administered with daptomycin. Both ezetimibe and simvastatin and daptomycin can cause myopathy and rhabdomyolysis when given alone and the risk of myopathy and rhabdomyolysis may be increased by co-administration. Temporarily suspend ezetimibe and simvastatin in patients taking daptomycin [see Warnings and Precautions (5.1)].

GERIATRIC USE SECTION.

8.5 Geriatric Use. Of the 10,189 patients who received ezetimibe and simvastatin in clinical studies, 3,242 (32%) were 65 and older (this included 844 (8%) who were 75 and older). No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients but greater sensitivity of some older individuals cannot be ruled out. Since advanced age (>=65 years) is predisposing factor for myopathy, ezetimibe and simvastatin should be prescribed with caution in the elderly [see Clinical Pharmacology (12.3)]. Because advanced age (>=65 years) is predisposing factor for myopathy, including rhabdomyolysis, ezetimibe and simvastatin should be prescribed with caution in the elderly. In clinical trial of patients treated with simvastatin 80 mg/day, patients >=65 years of age had an increased risk of myopathy, including rhabdomyolysis, compared to patients <65 years of age [see Warnings and Precautions (5.1) and Clinical Pharmacology (12.3) ].

INFORMATION FOR PATIENTS SECTION.

17 PATIENT COUNSELING INFORMATION. Advise the patient to read the FDA-approved patient labeling (Patient Information).Patients should be advised to adhere to their National Cholesterol Education Program (NCEP)-recommended diet, regular exercise program, and periodic testing of fasting lipid panel.Patients should be advised about substances they should not take concomitantly with ezetimibe and simvastatin [see Contraindications (4) and Warnings and Precautions (5.1)]. Patients should also be advised to inform other healthcare professionals prescribing new medication or increasing the dose of an existing medication that they are taking ezetimibe and simvastatin.. 17.1 Muscle Pain. All patients starting therapy with ezetimibe and simvastatin should be advised of the risk of myopathy, including rhabdomyolysis, and told to report promptly any unexplained muscle pain, tenderness or weakness particularly if accompanied by malaise or fever or if these muscle signs or symptoms persist after discontinuing ezetimibe and simvastatin. Patients using the 10/80-mg dose should be informed that the risk of myopathy, including rhabdomyolysis, is increased with the use of the 10/80-mg dose. The risk of myopathy, including rhabdomyolysis, occurring with use of ezetimibe and simvastatin is increased when taking certain types of medication or consuming grapefruit juice. Patients should discuss all medication, both prescription and over the counter, with their healthcare professional. 17.2 Liver Enzymes. It is recommended that liver function tests be performed before the initiation of ezetimibe and simvastatin, and thereafter when clinically indicated. All patients treated with ezetimibe and simvastatin should be advised to report promptly any symptoms that may indicate liver injury, including fatigue, anorexia, right upper abdominal discomfort, dark urine or jaundice.. 17.3 Pregnancy.

MECHANISM OF ACTION SECTION.

12.1 Mechanism of Action. Ezetimibe and simvastatinPlasma 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 reduces elevated total-C, LDL-C, Apo B, TG, and non-HDL-C, and increases HDL-C through dual inhibition of cholesterol absorption and synthesis.EzetimibeEzetimibe 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 (NPC1L1), which is involved in the intestinal uptake of cholesterol and phytosterols. In 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 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 decrease in the delivery of intestinal cholesterol to the liver. This causes 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)]. SimvastatinSimvastatin is prodrug and is hydrolyzed to its active -hydroxyacid form, simvastatin acid, after administration. Simvastatin is specific inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme (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.

NONCLINICAL TOXICOLOGY SECTION.

13 NONCLINICAL TOXICOLOGY. 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. Ezetimibe and simvastatinNo animal carcinogenicity or fertility studies have been conducted with the combination of ezetimibe and simvastatin. The combination of ezetimibe with simvastatin did not show evidence of mutagenicity in vitro in microbial mutagenicity (Ames) test with Salmonella typhimurium and Escherichia coli with or without metabolic activation. No evidence of clastogenicity was observed in vitro in chromosomal aberration assay in human peripheral blood lymphocytes with ezetimibe and simvastatin with or without metabolic activation. There was no evidence of genotoxicity at doses up to 600 mg/kg with the combination of ezetimibe and simvastatin (1:1) in the in vivo mouse micronucleus test. EzetimibeA 104-week dietary carcinogenicity study with ezetimibe was conducted in rats at doses up to 1,500 mg/kg/day (males) and 500 mg/kg/day (females) (~20 times the human exposure at 10 mg daily based on AUC 0-24hr for total ezetimibe). 104-week dietary carcinogenicity study with ezetimibe was also conducted in mice at doses up to 500 mg/kg/day (>150 times the human exposure at 10 mg daily based on AUC 0-24hr for total ezetimibe). There were no statistically significant increases in tumor incidences in drug-treated rats or mice. No evidence of mutagenicity was observed in vitro in microbial mutagenicity (Ames) test with Salmonella typhimurium and Escherichia coli with or without metabolic activation. No evidence of clastogenicity was observed in vitro in chromosomal aberration assay in human peripheral blood lymphocytes with or without metabolic activation. In addition, there was no evidence of genotoxicity in the in vivo mouse micronucleus test. In oral (gavage) fertility studies of ezetimibe conducted in rats, there was no evidence of reproductive toxicity at doses up to 1,000 mg/kg/day in male or female rats (~7 times the human exposure at 10 mg daily based on AUC 0-24hr for total ezetimibe). SimvastatinIn 72-week carcinogenicity study, mice were administered daily doses of simvastatin of 25, 100, and 400 mg/kg body weight, which resulted in mean plasma drug levels approximately 1, 4, and times higher than the mean human plasma drug level, respectively, (as total inhibitory activity based on AUC) after an 80-mg oral dose. Liver carcinomas were significantly increased in high-dose females and mid- and high-dose males with maximum incidence of 90% in males. The incidence of adenomas of the liver was significantly increased in mid- and high-dose females. Drug treatment also significantly increased the incidence of lung adenomas in mid- and high-dose males and females. Adenomas of the Harderian gland (a gland of the eye of rodents) were significantly higher in high-dose mice than in controls. No evidence of tumorigenic effect was observed at 25 mg/kg/day.In separate 92-week carcinogenicity study in mice at doses up to 25 mg/kg/day, no evidence of tumorigenic effect was observed (mean plasma drug levels were times higher than humans given 80 mg simvastatin as measured by AUC).In two-year study in rats at 25 mg/kg/day, there was statistically significant increase in the incidence of thyroid follicular adenomas in female rats exposed to approximately 11 times higher levels of simvastatin than in humans given 80 mg simvastatin (as measured by AUC).A second two-year rat carcinogenicity study with doses of 50 and 100 mg/kg/day produced hepatocellular adenomas and carcinomas (in female rats at both doses and in males at 100 mg/kg/day). Thyroid follicular cell adenomas were increased in males and females at both doses; thyroid follicular cell carcinomas were increased in females at 100 mg/kg/day. The increased incidence of thyroid neoplasms appears to be consistent with findings from other statins. These treatment levels represented plasma drug levels (AUC) of approximately and 15 times (males) and 22 and 25 times (females) the mean human plasma drug exposure after an 80-mg daily dose.No evidence of mutagenicity was observed in microbial mutagenicity (Ames) test with or without rat or mouse liver metabolic activation. In addition, no evidence of damage to genetic material was noted in an in vitro alkaline elution assay using rat hepatocytes, V-79 mammalian cell forward mutation study, an in vitro chromosome aberration study in CHO cells, or an in vivo chromosomal aberration assay in mouse bone marrow. There was decreased fertility in male rats treated with simvastatin for 34 weeks at 25 mg/kg body weight (4 times the maximum human exposure level, based on AUC, in patients receiving 80 mg/day); however, this effect was not observed during subsequent fertility study in which simvastatin was administered at this same dose level to male rats for 11 weeks (the entire cycle of spermatogenesis including epididymal maturation). No microscopic changes were observed in the testes of rats from either study. At 180 mg/kg/day (which produces exposure levels 22 times higher than those in humans taking 80 mg/day based on surface area, mg/m 2), seminiferous tubule degeneration (necrosis and loss of spermatogenic epithelium) was observed. In dogs, there was drug-related testicular atrophy, decreased spermatogenesis, spermatocytic degeneration and giant cell formation at 10 mg/kg/day (approximately times the human exposure, based on AUC, at 80 mg/day). The clinical significance of these findings is unclear. 13.2 Animal Toxicology and/or Pharmacology. CNS ToxicityOptic nerve degeneration was seen in clinically normal dogs treated with simvastatin for 14 weeks at 180 mg/kg/day, dose that produced mean plasma drug levels about 12 times higher than the mean plasma drug level in humans taking 80 mg/day.A chemically similar drug in this class also produced optic nerve degeneration (Wallerian degeneration of retinogeniculate fibers) in clinically normal dogs in dose-dependent fashion starting at 60 mg/kg/day, dose that produced mean plasma drug levels about 30 times higher than the mean plasma drug level in humans taking the highest recommended dose (as measured by total enzyme inhibitory activity). This same drug also produced vestibulocochlear Wallerian-like degeneration and retinal ganglion cell chromatolysis in dogs treated for 14 weeks at 180 mg/kg/day, dose that resulted in mean plasma drug level similar to that seen with the 60 mg/kg/day dose.CNS vascular lesions, characterized by perivascular hemorrhage and edema, mononuclear cell infiltration of perivascular spaces, perivascular fibrin deposits and necrosis of small vessels, were seen in dogs treated with simvastatin at dose of 360 mg/kg/day, dose that produced mean plasma drug levels that were about 14 times higher than the mean plasma drug levels in humans taking 80 mg/day. Similar CNS vascular lesions have been observed with several other drugs of this class.There were cataracts in female rats after two years of treatment with 50 and 100 mg/kg/day (22 and 25 times the human AUC at 80 mg/day, respectively) and in dogs after three months at 90 mg/kg/day (19 times) and at two years at 50 mg/kg/day (5 times).EzetimibeThe hypocholesterolemic effect of ezetimibe was evaluated in cholesterol-fed Rhesus monkeys, dogs, rats, and mouse models of human cholesterol metabolism. Ezetimibe was found to have an ED 50 value of 0.5 mcg/kg/day for inhibiting the rise in plasma cholesterol levels in monkeys. The ED 50 values in dogs, rats, and mice were 7, 30, and 700 mcg/kg/day, respectively. These results are consistent with ezetimibe being potent cholesterol absorption inhibitor. In rat model, where the glucuronide metabolite of ezetimibe (ezetimibe-glucuronide) was administered intraduodenally, the metabolite was as potent as ezetimibe in inhibiting the absorption of cholesterol, suggesting that the glucuronide metabolite had activity similar to the parent drug.In 1-month studies in dogs given ezetimibe (0.03 mg/kg/day to 300 mg/kg/day), the concentration of cholesterol in gallbladder bile increased ~2- to 4-fold. However, dose of 300 mg/kg/day administered to dogs for one year did not result in gallstone formation or any other adverse hepatobiliary effects. In 14-day study in mice given ezetimibe (0.3 mg/kg/day to mg/kg/day) and fed low-fat or cholesterol-rich diet, the concentration of cholesterol in gallbladder bile was either unaffected or reduced to normal levels, respectively.A series of acute preclinical studies was performed to determine the selectivity of ezetimibe for inhibiting cholesterol absorption. Ezetimibe inhibited the absorption of 14C-cholesterol with no effect on the absorption of triglycerides, fatty acids, bile acids, progesterone, ethinyl estradiol, or the fat-soluble vitamins and D. In 4- to 12-week toxicity studies in mice, ezetimibe did not induce cytochrome P450 drug-metabolizing enzymes. In toxicity studies, pharmacokinetic interaction of ezetimibe with statins (parents or their active hydroxy acid metabolites) was seen in rats, dogs, and rabbits.

NURSING MOTHERS SECTION.

8.3 Nursing Mothers. It is not known whether simvastatin is excreted in human milk. Because small amount of another drug in this class is excreted in human milk and because of the potential for serious adverse reactions in nursing infants, women taking simvastatin should not nurse their infants. decision should be made whether to discontinue nursing or discontinue drug, taking into account the importance of the drug to the mother [see Contraindications (4)]. In rat studies, exposure to ezetimibe in nursing pups was up to half of that observed in maternal plasma. It is not known whether ezetimibe or simvastatin are excreted into human breast milk. Because small amount of another drug in the same class as simvastatin is excreted in human milk and because of the potential for serious adverse reactions in nursing infants, women who are nursing should not take ezetimibe and simvastatin [see Contraindications (4)].

OVERDOSAGE SECTION.

10 OVERDOSAGE. Ezetimibe and simvastatinNo specific treatment of overdosage with ezetimibe and simvastatin can be recommended. In the event of an overdose, symptomatic and supportive measures should be employed.EzetimibeIn 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. few cases of overdosage have been reported; most have not been associated with adverse experiences. Reported adverse experiences have not been serious.SimvastatinSignificant lethality was observed in mice after single oral dose of 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. 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.

PEDIATRIC USE SECTION.

8.4 Pediatric Use. The effects of ezetimibe co-administered with simvastatin (n=126) compared to simvastatin monotherapy (n=122) have been evaluated in adolescent boys and girls with heterozygous familial hypercholesterolemia (HeFH). In multicenter, double-blind, controlled study followed by an open-label phase, 142 boys and 106 postmenarchal girls, 10 to 17 years of age (mean age 14.2 years, 43% females, 82% Caucasians, 4% Asian, 2% Blacks, 13% multiracial) with HeFH were randomized to receive either ezetimibe co-administered with simvastatin or simvastatin monotherapy. Inclusion in the study required 1) baseline LDL-C level between 160 and 400 mg/dL and 2) medical history and clinical presentation consistent with HeFH. The mean baseline LDL-C value was 225 mg/dL (range: 161 mg/dL to 351 mg/dL) in the ezetimibe co-administered with simvastatin group compared to 219 mg/dL (range: 149 mg/dL to 336 mg/dL) in the simvastatin monotherapy group. The patients received co-administered ezetimibe and simvastatin (10 mg, 20 mg, or 40 mg) or simvastatin monotherapy (10 mg, 20 mg, or 40 mg) for weeks, co-administered ezetimibe and 40 mg simvastatin or 40 mg simvastatin monotherapy for the next 27 weeks, and open-label co-administered ezetimibe and simvastatin (10 mg, 20 mg, or 40 mg) for 20 weeks thereafter.The results of the study at Week are summarized in Table 3. Results at Week 33 were consistent with those at Week 6.Table 3: Mean Percent Difference at Week Between the Pooled Ezetimibe Co-administered with Simvastatin Group and the Pooled Simvastatin Monotherapy Group in Adolescent Patients with Heterozygous Familial HypercholesterolemiaTotal-CLDL-CApo BNon-HDL-CTG HDL-CMean percent difference between treatment groups-12%-15%-12%-14%-2%+0.1%95% Confidence Interval(-15%, -9%)(-18%, -12%)(-15%, -9%)(-17%, -11%)(-9, +4)(-3, +3) For triglycerides, median change from baseline. From the start of the trial to the end of Week 33, discontinuations due to an adverse reaction occurred in (6%) patients in the ezetimibe co-administered with simvastatin group and in (2%) patients in the simvastatin monotherapy group.During the trial, hepatic transaminase elevations (two consecutive measurements for ALT and/or AST >=3 ULN) occurred in four (3%) individuals in the ezetimibe co-administered with simvastatin group and in two (2%) individuals in the simvastatin monotherapy group. Elevations of CPK (>=10 ULN) occurred in two (2%) individuals in the ezetimibe co-administered with simvastatin group and in zero individuals in the simvastatin monotherapy group.In this limited controlled study, there was no significant effect on growth or sexual maturation in the adolescent boys or girls, or on menstrual cycle length in girls.Co-administration of ezetimibe with simvastatin at doses greater than 40 mg/day has not been studied in adolescents. Also, ezetimibe and simvastatin has not been studied in patients younger than 10 years of age or in pre-menarchal girls.EzetimibeBased on total ezetimibe (ezetimibe ezetimibe-glucuronide) there are no pharmacokinetic differences between adolescents and adults. Pharmacokinetic data in the pediatric population <10 years of age are not available.SimvastatinThe pharmacokinetics of simvastatin has not been studied in the pediatric population.

PHARMACODYNAMICS SECTION.

12.2 Pharmacodynamics. Clinical studies have demonstrated that elevated levels of total-C, LDL-C and Apo B, the major protein constituent of LDL, promote human atherosclerosis. In addition, decreased levels of HDL-C are associated with the development of atherosclerosis. Epidemiologic studies have established that cardiovascular morbidity and mortality vary directly with the level of total-C and LDL-C and inversely with the level of HDL-C. Like LDL, cholesterol-enriched triglyceride-rich lipoproteins, including VLDL, intermediate-density lipoproteins (IDL), and remnants, can also promote atherosclerosis. The independent effect of raising HDL-C or lowering TG on the risk of coronary and cardiovascular morbidity and mortality has not been determined.

PHARMACOKINETICS SECTION.

12.3 Pharmacokinetics. The results of bioequivalence study in healthy subjects demonstrated that the ezetimibe and simvastatin 10 mg/10 mg to 10 mg/80 mg combination tablets are bioequivalent to co-administration of corresponding doses of ezetimibe (ZETIA (R)) and simvastatin (ZOCOR (R)) as individual tablets. AbsorptionEzetimibeAfter oral administration, ezetimibe is absorbed and extensively conjugated to pharmacologically active phenolic glucuronide (ezetimibe-glucuronide).SimvastatinThe availability of the -hydroxyacid to the systemic circulation following an oral dose of simvastatin was found to be less than 5% of the dose, consistent with extensive hepatic first-pass extraction.Effect of Food on Oral AbsorptionEzetimibeConcomitant food administration (high-fat or non-fat meals) had no effect on the extent of absorption of ezetimibe when administered as 10-mg tablets. The max value of ezetimibe was increased by 38% with consumption of high-fat meals. SimvastatinRelative to the fasting state, the plasma profiles of both active and total inhibitors of HMG-CoA reductase were not affected when simvastatin was administered immediately before an American Heart Association recommended low-fat meal.DistributionEzetimibeEzetimibe and ezetimibe-glucuronide are highly bound (>90%) to human plasma proteins.SimvastatinBoth simvastatin and its -hydroxyacid metabolite are highly bound (approximately 95%) to human plasma proteins. When radiolabeled simvastatin was administered to rats, simvastatin-derived radioactivity crossed the blood-brain barrier.Metabolism and ExcretionEzetimibeEzetimibe is primarily metabolized in the small intestine and liver via glucuronide conjugation with subsequent biliary and renal excretion. Minimal oxidative metabolism has been observed in all species evaluated.In humans, ezetimibe is rapidly metabolized to ezetimibe-glucuronide. Ezetimibe and ezetimibe-glucuronide are the major drug-derived compounds detected in plasma, constituting approximately 10 to 20% and 80 to 90% of the total drug in plasma, respectively. Both ezetimibe and ezetimibe-glucuronide are eliminated from plasma with half-life of approximately 22 hours for both ezetimibe and ezetimibe-glucuronide. Plasma concentration-time profiles exhibit multiple peaks, suggesting enterohepatic recycling.Following oral administration of 14C-ezetimibe (20 mg) to human subjects, total ezetimibe (ezetimibe ezetimibe-glucuronide) accounted for approximately 93% of the total radioactivity in plasma. After 48 hours, there were no detectable levels of radioactivity in the plasma. Approximately 78% and 11% of the administered radioactivity were recovered in the feces and urine, respectively, over 10-day collection period. Ezetimibe was the major component in feces and accounted for 69% of the administered dose, while ezetimibe-glucuronide was the major component in urine and accounted for 9% of the administered dose.SimvastatinSimvastatin is lactone that is readily hydrolyzed in vivo to the corresponding -hydroxyacid, potent inhibitor of HMG-CoA reductase. Inhibition of HMG-CoA reductase is basis for an assay in pharmacokinetic studies of the -hydroxyacid metabolites (active inhibitors) and, following base hydrolysis, active plus latent inhibitors (total inhibitors) in plasma following administration of simvastatin. The major active metabolites of simvastatin present in human plasma are the -hydroxyacid of simvastatin and its 6-hydroxy, 6-hydroxymethyl, and 6-exomethylene derivatives. Following an oral dose of 14C-labeled simvastatin in man, 13% of the dose was excreted in urine and 60% in feces. Plasma concentrations of total radioactivity (simvastatin plus 14C-metabolites) peaked at hours and declined rapidly to about 10% of peak by 12 hours postdose. Specific PopulationsGeriatric PatientsEzetimibeIn multiple-dose study with ezetimibe given 10 mg once daily for 10 days, plasma concentrations for total ezetimibe were about 2-fold higher in older (>=65 years) healthy subjects compared to younger subjects.SimvastatinIn study including 16 elderly patients between 70 and 78 years of age who received simvastatin 40 mg/day, the mean plasma level of HMG-CoA reductase inhibitory activity was increased approximately 45% compared with 18 patients between 18 to 30 years of age.Pediatric Patients: [see Use in Specific Populations (8.4)]. GenderEzetimibeIn multiple-dose study with ezetimibe given 10 mg once daily for 10 days, plasma concentrations for total ezetimibe were slightly higher (<20%) in women than in men.RaceEzetimibeBased on meta-analysis of multiple-dose pharmacokinetic studies, there were no pharmacokinetic differences between Black and Caucasian subjects. Studies in Asian subjects indicated that the pharmacokinetics of ezetimibe was similar to those seen in Caucasian subjects.Hepatic ImpairmentEzetimibeAfter single 10-mg dose of ezetimibe, the mean exposure (based on area under the curve [AUC]) to total ezetimibe was increased approximately 1.7-fold in patients with mild hepatic impairment (Child-Pugh score to 6), compared to healthy subjects. The mean AUC values for total ezetimibe and ezetimibe increased approximately 3- to 4-fold and 5- to 6-fold, respectively, in patients with moderate (Child-Pugh score to 9) or severe hepatic impairment (Child-Pugh score 10 to 15). In 14-day, multiple-dose study (10 mg daily) in patients with moderate hepatic impairment, the mean AUC for total ezetimibe and ezetimibe increased approximately 4-fold compared to healthy subjects.Renal ImpairmentEzetimibeAfter single 10-mg dose of ezetimibe in patients with severe renal disease (n=8; mean CrCl <=30 mL/min/1.73 2), the mean AUC for total ezetimibe and ezetimibe increased approximately 1.5-fold, compared to healthy subjects (n=9). SimvastatinPharmacokinetic studies with another statin having similar principal route of elimination to that of simvastatin have suggested that for given dose level higher systemic exposure may be achieved in patients with severe renal impairment (as measured by creatinine clearance).Drug Interactions [see also Drug Interactions (7)].No clinically significant pharmacokinetic interaction was seen when ezetimibe was co-administered with simvastatin. No specific pharmacokinetic drug interaction studies with ezetimibe and simvastatin have been conducted other than the following study with NIASPAN (Niacin extended-release tablets).Niacin: The effect of ezetimibe and simvastatin (10/20 mg daily for days) on the pharmacokinetics of NIASPAN extended-release tablets (1,000 mg for days and 2,000 mg for days following low-fat breakfast) was studied in healthy subjects. The mean max and AUC of niacin increased 9% and 22%, respectively. The mean max and AUC of nicotinuric acid increased 10% and 19%, respectively (N=13). In the same study, the effect of NIASPAN on the pharmacokinetics of ezetimibe and simvastatin was evaluated (N=15). While concomitant NIASPAN decreased the mean max of total ezetimibe (1%), and simvastatin (2%), it increased the mean max of simvastatin acid (18%). In addition, concomitant NIASPAN increased the mean AUC of total ezetimibe (26%), simvastatin (20%), and simvastatin acid (35%). Cases of myopathy/rhabdomyolysis have been observed with simvastatin co-administered with lipid-modifying doses (>=1 g/day niacin) of niacin-containing products [see Warnings and Precautions (5.1) and Drug Interactions (7.4)] Cytochrome P450: Ezetimibe had no significant effect on series of probe drugs (caffeine, dextromethorphan, tolbutamide, and IV midazolam) known to be metabolized by cytochrome P450 (1A2, 2D6, 2C8/9 and 3A4) in cocktail study of twelve healthy adult males. This indicates that ezetimibe is neither an inhibitor nor an inducer of these cytochrome P450 isozymes, and it is unlikely that ezetimibe will affect the metabolism of drugs that are metabolized by these enzymes. In study of 12 healthy volunteers, simvastatin at the 80-mg dose had no effect on the metabolism of the probe cytochrome P450 isoform 3A4 (CYP3A4) substrates midazolam and erythromycin. This indicates that simvastatin is not an inhibitor of CYP3A4 and, therefore, is not expected to affect the plasma levels of other drugs metabolized by CYP3A4.Simvastatin acid is substrate of the transport protein OATP1B1. Concomitant administration of medicinal products that are inhibitors of the transport protein OATP1B1 may lead to increased plasma concentrations of simvastatin acid and an increased risk of myopathy. For example, cyclosporine has been shown to increase the AUC of statins; although the mechanism is not fully understood, the increase in AUC for simvastatin acid is presumably due, in part, to inhibition of CYP3A4 and/or OATP1B1.Simvastatin is substrate for CYP3A4. Inhibitors of CYP3A4 can raise the plasma levels of HMG-CoA reductase inhibitory activity and increase the risk of myopathy [see Warnings and Precautions (5.1); Drug Interactions (7.1)] EzetimibeTable 4: Effect of Co-administered Drugs on Total EzetimibeCo-administered Drug and Dosing RegimenTotal Ezetimibe Change in AUCChange in max Cyclosporine-stable dose required (75 mg to 150 mg BID) +, 240%290%Fenofibrate, 200 mg QD, 14 days 48%64%Gemfibrozil, 600 mg BID, days 64%91%Cholestyramine, g BID, 14 days 55%4%Aluminum magnesium hydroxide combination antacid, single dose 4%30%Cimetidine, 400 mg BID, days6%22%Glipizide, 10 mg, single dose4%8%StatinsLovastatin 20 mg QD, days9%3%Pravastatin 20 mg QD, 14 days7%23%Atorvastatin 10 mg QD, 14 days2%12%Rosuvastatin 10 mg QD, 14 days13%18%Fluvastatin 20 mg QD, 14 days19%7% Based on 10 mg-dose of ezetimibe.+ Post-renal transplant patients with mild impaired or normal renal function.

PREGNANCY SECTION.

8.1 Pregnancy. Pregnancy Category X.[See Contraindications (4)].Ezetimibe and simvastatinEzetimibe and simvastatin is contraindicated in women who are or may become pregnant. Lipid-lowering drugs offer no benefit during pregnancy, because cholesterol and cholesterol derivatives are needed for normal fetal development. Atherosclerosis is chronic process, and discontinuation of lipid-lowering drugs during pregnancy should have little impact on long-term outcomes of primary hypercholesterolemia therapy. There are no adequate and well-controlled studies of ezetimibe and simvastatin use during pregnancy; however, there are rare reports of congenital anomalies in infants exposed to statins in utero. Animal reproduction studies of simvastatin in rats and rabbits showed no evidence of teratogenicity. Serum cholesterol and triglycerides increase during normal pregnancy, and cholesterol or cholesterol derivatives are essential for fetal development. Because 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 pregnant woman. If ezetimibe and simvastatin is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus. Women of childbearing potential, who require ezetimibe and simvastatin treatment for lipid disorder, should be advised to use effective contraception. For women trying to conceive, discontinuation of ezetimibe and simvastatin should be considered. If pregnancy occurs, ezetimibe and simvastatin should be immediately discontinued.EzetimibeIn oral (gavage) embryo-fetal development studies of ezetimibe conducted in rats and rabbits during organogenesis, there was no evidence of embryolethal effects at the doses tested (250, 500, 1,000 mg/kg/day). In rats, increased incidences of common fetal skeletal findings (extra pair of thoracic ribs, unossified cervical vertebral centra, shortened ribs) were observed at 1,000 mg/kg/day (~10 times the human exposure at 10 mg daily based on AUC 0-24hr for total ezetimibe). In rabbits treated with ezetimibe, an increased incidence of extra thoracic ribs was observed at 1,000 mg/kg/day (150 times the human exposure at 10 mg daily based on AUC 0-24hr for total ezetimibe). Ezetimibe crossed the placenta when pregnant rats and rabbits were given multiple oral doses. Multiple-dose studies of ezetimibe co-administered with statins in rats and rabbits during organogenesis result in higher ezetimibe and statin exposures. Reproductive findings occur at lower doses in co-administration therapy compared to monotherapy.SimvastatinSimvastatin was not teratogenic in rats or rabbits at doses (25 mg/kg/day, 10 mg/kg/day, respectively) that resulted in times the human exposure based on mg/m surface area. However, in studies with another structurally-related statin, skeletal malformations were observed in rats and mice. There are rare reports of congenital anomalies following intrauterine exposure to statins. In review of approximately 100 prospectively followed pregnancies in women exposed to simvastatin or another structurally-related statin, the incidences of congenital anomalies, spontaneous abortions and fetal deaths/stillbirths did not exceed what would be expected in the general population. The number of cases is adequate only to exclude 3- to 4-fold increase in congenital anomalies over the background incidence. In 89% of the prospectively followed pregnancies, drug treatment was initiated prior to pregnancy and was discontinued at some point in the first trimester when pregnancy was identified.
