Adverse Reactions

6 ADVERSE REACTIONS The following serious adverse reactions are discussed in greater detail in other sections of the label: • Liver enzyme abnormalities [see Warnings and Precautions (5.2)] • Rhabdomyolysis and myopathy [see Warnings and Precautions (5.3)] Common adverse reactions in clinical trials: Ezetimibe tablets administered alone (incidence ≥2% and greater than placebo): upper respiratory tract infection, diarrhea, arthralgia, sinusitis, pain in extremity, fatigue, and influenza (6.1) Ezetimibe tablets coadministered with a statin (incidence ≥2% and greater than statin alone): nasopharyngitis, myalgia, upper respiratory tract infection, arthralgia, diarrhea, back pain, influenza, pain in extremity, and fatigue (6.1) To report SUSPECTED ADVERSE REACTIONS, contact Ohm Laboratories Inc. at 1-800- 406-7984 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. [see Warnings and Precautions (5.2)] [see Warnings and Precautions (5.3)] 6.1 Clinical Trials Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in clinical practice. Monotherapy In 10 double-blind, placebo-controlled clinical trials, 2,396 patients with primary hyperlipidemia (age range 9 to 86 years; 50% female, 90% White, 5% Black or African American, 2% Asian, 3% other races; 3% identified as Hispanic or Latino ethnicity) and elevated LDL-C were treated with ezetimibe tablets 10 mg daily for a median treatment duration of 12 weeks (range 0 to 39 weeks). Adverse reactions reported in ≥ 2% of patients treated with ezetimibe tablets and at an incidence greater than placebo in placebo-controlled studies of ezetimibe tablets are shown in Table 1. TABLE 1: Adverse Reactions Occurring in ≥ 2% and Greater than Placebo in ezetimibe tablets -treated Patients Adverse Reactions Placebo (%) n=1,159 Ezetimibe tablets 10mg (%) n=2,396 Upper respiratory tract infection 2.5 4.3 Diarrhea 3.7 4.1 Arthralgia 2.2 3.0 Sinusitis 2.2 2.8 Pain in extremity 2.5 2.7 Fatigue 1.5 2.4 1.5 2.0 Combination with a Statin In 28 double-blind, controlled (placebo or active-controlled) clinical trials, 11,308 patients with primary hyperlipidemia (age range 10 to 93 years, 48% female, 85% White, 7% Black or African American, 3% Asian, 5% other races; 4% identified as Hispanic or Latino ethnicity) and elevated LDL-C were treated with ezetimibe tablets 10 mg/day concurrently with or added to on-going statin therapy for a median treatment duration of 8 weeks (range 0 to 112 weeks). The incidence of consecutive increased transaminases (≥ 3 times ULN) was higher in patients receiving ezetimibe tablets administered with statins (1.3%) than in patients treated with statins alone (0.4%). Adverse reactions reported in ≥2% of patients treated with ezetimibe tablets + statin and at an incidence greater than statin are shown in Table 2.

Incidence rates for clinically important elevations (≥3 X ULN, consecutive) in hepatic transaminase levels were 4.5% and 2.7% for fenofibrate monotherapy (n=188) and ezetimibe tablets co-administered with fenofibrate (n=183), respectively, adjusted for treatment exposure. Corresponding incidence rates for cholecystectomy were 0.6% and 1.7% for fenofibrate monotherapy and ezetimibe tablets co-administered with fenofibrate, respectively [see Drug Interactions (7) ]. 6.2 Post-Marketing Experience Because the reactions below are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The following additional adverse reactions have been identified during post-approval use of ezetimibe tablets: Blood Disorders: thrombocytopenia Gastrointestinal Disorders: abdominal pain; pancreatitis; nausea Hepatobiliary Disorders: elevations in liver transaminases; hepatitis; cholelithiasis; cholecystitis Immune System Disorders: Hypersensitivity reactions including: anaphylaxis, angioedema, rash, and urticaria Musculoskeletal Disorders: elevated creatine phosphokinase; myopathy/rhabdomyolysis Nervous System Disorders: dizziness; paresthesia; depression; headache Skin and Subcutaneous Tissue Disorders: erythema multiforme

Drug Interactions

7 DRUG INTERACTIONS Table 3 includes a list of drugs with clinically important drug interactions when administered concomitantly with ezetimibe and instructions for preventing or managing them. Table 3 Clinically Important Drug Interactions with Ezetimibe Tablets Cyclosporine Clinical Impact Concomitant use of ezetimibe tablets and cyclosporine increases ezetimibe and cyclosporine concentrations. The degree of increase in ezetimibe exposure may be greater in patients with severe renal insufficiency [see Clinical Pharmacology ( 12.3 )] . Intervention Monitor cyclosporine concentrations in patients receiving ezetimibe tablets and cyclosporine. In patients treated with cyclosporine, weigh the potential effects of the increased exposure to ezetimibe from concomitant use against the benefits of alterations in lipid levels provided by ezetimibe tablets. Fibrates Clinical Impact Both fenofibrate and ezetimibe may increase cholesterol excretion into the bile, leading to cholelithiasis. Co-administration of ezetimibe tablets with fibrates other than fenofibrate is not recommended [see Adverse Reactions ( 6.1 )] . Intervention If cholelithiasis is suspected in a patient receiving ezetimibe tablets and fenofibrate, gallbladder studies are indicated, and alternative lipid-lowering therapy should be considered. Bile Acid Sequestrants Clinical Impact Concomitant cholestyramine administration decreased the mean exposure of total ezetimibe. This may result in a reduction of efficacy [see Clinical Pharmacology ( 12.3 )] . Intervention In patients taking a bile acid sequestrant, administer ezetimibe tablets at least 2 hours before or 4 hours after the bile acid sequestrant [see Dosage and Administration ( 2 )] . Cyclosporine: Combination increases exposure of ezetimibe tablets and cyclosporine. Cyclosporine concentrations should be monitored in patients taking ezetimibe tablets concomitantly. (7) Fibrates: Co-administration of ezetimibe tablets with fibrates other than fenofibrate is not recommended until use in patients is adequately studied. If cholelithiasis is suspected in a patient receiving ezetimibe tablets and fenofibrate, gallbladder studies are indicated, and alternative lipid-lowering therapy should be considered. (7) Bile Acid Sequestrants: Cholestyramine combination decreases exposure of ezetimibe tablets. (7) See 17 for PATIENT COUNSELING INFORMATION and FDA-approved patient labeling.

Clinical Pharmacology

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Ezetimibe reduces blood cholesterol by inhibiting the absorption of cholesterol by the small intestine. The molecular target of ezetimibe has been shown to be the sterol transporter, Niemann-Pick C1-Like 1 (NPC1L1), which is involved in the intestinal uptake of cholesterol and phytosterols. Ezetimibe localizes at the brush border of the small intestine and inhibits the absorption of cholesterol, leading to a decrease in the delivery of intestinal cholesterol to the liver. This causes a reduction of hepatic cholesterol stores and an increase in LDL receptors, resulting in clearance of cholesterol from the blood. 12.2 Pharmacodynamics Ezetimibe tablets reduces total cholesterol (total-C), LDL-C, apolipoprotein (Apo) B, and non-high-density lipoprotein cholesterol (non-HDL-C) in patients with hyperlipidemia. In a 2-week clinical trial in 18 hypercholesterolemic patients, ezetimibe tablets inhibited intestinal cholesterol absorption by 54%, compared with placebo. Ezetimibe tablets had no clinically meaningful effect on the plasma concentrations of the fat-soluble vitamins A, D, and E (in a trial of 113 patients) and did not impair adrenocortical steroid hormone production (in a trial of 118 patients). 12.3 Pharmacokinetics Absorption After oral administration, ezetimibe is absorbed and extensively conjugated to a pharmacologically active phenolic glucuronide (ezetimibe-glucuronide). After a single 10 mg dose of ezetimibe tablets to fasted adults, mean ezetimibe peak plasma concentrations (C max ) of 3.4 to 5.5 ng/mL were attained within 4 to 12 hours (T max ). Ezetimibe-glucuronide mean C max values of 45 to 71 ng/mL were achieved between 1 and 2 hours (T max ). There was no substantial deviation from dose proportionality between 5 and 20 mg. The absolute bioavailability of ezetimibe cannot be determined, as the compound is virtually insoluble in aqueous media suitable for injection. Effect of Food Concomitant food administration (high-fat or non-fat meals) had no effect on the extent of absorption of ezetimibe when administered as ezetimibe 10 mg tablets. The C max value of ezetimibe was increased by 38% with consumption of high-fat meals. Distribution Ezetimibe and ezetimibe-glucuronide are highly bound (> 90%) to human plasma proteins. Elimination Metabolism Ezetimibe is primarily metabolized in the small intestine and liver via glucuronide conjugation (a phase II reaction) with subsequent biliary and renal excretion. Minimal oxidative metabolism (a phase I reaction) 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 a half-life of approximately 22 hours for both ezetimibe and ezetimibe-glucuronide. Plasma concentration-time profiles exhibit multiple peaks, suggesting enterohepatic recycling Excretion Following oral administration of 14 C-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 a 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. Specific Populations Geriatric Patients : In a multiple-dose trial 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. However, the difference in plasma concentrations is not clinically meaningful. Gender : In a multiple-dose trial with ezetimibe given 10 mg once daily for 10 days, plasma concentrations for total ezetimibe were slightly higher (< 20%) in females than in males. Race : Based on a meta-analysis of multiple-dose pharmacokinetic studies, there were no pharmacokinetic differences between Black and White subjects. Studies in Asian subjects indicated that the pharmacokinetics of ezetimibe were similar to those seen in White subjects. Renal Impairment: After a single 10-mg dose of ezetimibe in patients with severe renal disease (n=8; mean CrCl ≤30 mL/min/1.73 m 2 ), the mean AUC values for total ezetimibe, ezetimibe-glucuronide, and ezetimibe were increased approximately 1.5-fold, compared to healthy subjects (n=9). Hepatic Impairment: After a single 10-mg dose of ezetimibe, the mean AUC for total ezetimibe was increased approximately 1.7-fold in patients with mild hepatic impairment (Child-Pugh score 5 to 6), compared to healthy subjects. The mean AUC values for total ezetimibe and ezetimibe were increased approximately 3-to 4-fold and 5-to 6-fold, respectively, in patients with moderate (Child-Pugh score 7 to 9) or severe hepatic impairment (Child-Pugh score 10 to 15). In a 14-day, multiple-dose trial (10 mg daily) in patients with moderate hepatic impairment, the mean AUC values for total ezetimibe and ezetimibe were increased approximately 4-fold on Day 1 and Day 14 compared to healthy subjects [see Use in Specific Populations (8.7)] . Drug Interactions Ezetimibe tablets had no significant effect on a series of probe drugs (caffeine, dextromethorphan, tolbutamide, and IV midazolam) known to be metabolized by cytochrome P450 (1A2, 2D6, 2C8/9 and 3A4) in a “cocktail” trial 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.

Nonclinical Toxicology

13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility A 104-week dietary carcinogenicity study with ezetimibe was conducted in rats at doses up to 1500 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). A 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 a microbial mutagenicity (Ames) test with Salmonella typhimurium and Escherichia coli with or without metabolic activation. No evidence of clastogenicity was observed in vitro in a 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 1000 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).

Clinical Studies

14 CLINICAL STUDIES Primary Hyperlipidemia in Adults Ezetimibe tablets reduces total-C, LDL-C, Apo B, and non-HDL-C in patients with hyperlipidemia. Maximal to near maximal response is generally achieved within 2 weeks and maintained during chronic therapy. Monotherapy In two multicenter, double-blind, placebo-controlled, 12-week trials in 1719 patients (age range 18 to 86 years, 52% females; 91% White, 5% Black or African American, 1% Asian, 3% other races mostly identified as Hispanic or Latino ethnicity) with primary hyperlipidemia, ezetimibe tablets significantly lowered total-C, LDL-C, Apo B, and non-HDL-C compared to placebo (see Table 7). Reduction in LDL-C was consistent across age, sex, and baseline LDL-C.

Use In Specific Populations

8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Risk Summary There are insufficient data on ezetimibe use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. In animal reproduction studies, no adverse developmental effects were observed in pregnant rats and rabbits orally administered ezetimibe during the period of organogenesis at doses that resulted in up to 10 and 150 times, respectively, the human exposure at the MRHD, based on AUC (see Data) . Ezetimibe tablets should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. When ezetimibe tablets are administered with a statin, refer to the Prescribing Information for the statin. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Animal Data In oral (gavage) embryo-fetal development studies of ezetimibe conducted in rats (gestation days 6-15) and rabbits (gestation days 7-19), there was no evidence of maternal toxicity or 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). The animal-to-human exposure multiple for total ezetimibe at the no-observed effect level was 6 times for rat and 134 times for rabbit. Fetal exposure to ezetimibe (conjugated and unconjugated) was confirmed in subsequent placental transfer studies conducted using a maternal dose of 1,000 mg/kg/day. The fetal maternal plasma exposure ratio (total ezetimibe) was 1.5 for rats on gestation day 20 and 0.03 for rabbits on gestation day 22. The effect of ezetimibe on prenatal and postnatal development and maternal function was evaluated in pregnant rats at doses of 100, 300 or 1,000 mg/kg/day from gestation day 6 through lactation day 21. No maternal toxicity or adverse developmental outcomes were observed up to and including the highest dose tested (17 times the human exposure at 10 mg daily based on AUC 0-24hr for total ezetimibe). Multiple-dose studies of ezetimibe given in combination with statins in rats and rabbits during organogenesis resulted in higher ezetimibe and statin exposures. Reproductive findings occurred at lower doses in combination therapy compared to monotherapy. 8.2 Lactation Risk Summary There is no information about the presence of ezetimibe in human milk. Ezetimibe is present in rat milk (see Data) . When a drug is present in animal milk, it is likely that the drug will be present in human milk. There is no information about the effects of ezetimibe on the breastfed infant or the effects of ezetimibe on milk production. Ezetimibe tablets should not be used in nursing mothers unless the potential benefit justifies the potential risk to the infant. Data Ezetimibe was present in the milk of lactating rats. The pup to maternal plasma ratio for total ezetimibe was 0.5 on lactation day 12. 8.4 Pediatric Use The safety and effectiveness of ezetimibe tablets in combination with a statin as an adjunct to diet to reduce LDL-C have been established in pediatric patients 10 years of age and older with HeFH. Use of ezetimibe tablets for this indication is based on a double-blind, placebo-controlled clinical trial in 248 pediatric patients (142 males and 106 postmenarchal females) 10 years of age and older with HeFH [ see Clinical Studies (14) ] . In this limited controlled trial, there was no significant effect on growth or sexual maturation in the adolescent males or females, or on menstrual cycle length in females. The safety and effectiveness of ezetimibe tablets in combination with a statin, and other LDL-C lowering therapies, to reduce LDL-C have been established in pediatric patients 10 years of age and older with HoFH. Use of ezetimibe tablets for this indication is based on a 12-week double-blind, placebo-controlled clinical trial followed by an uncontrolled extension period in 7 pediatric patients 11 years of age and older with HoFH [ see Clinical Studies (14) ] . The safety and effectiveness of ezetimibe tablets as an adjunct to diet for the reduction of elevated sitosterol and campesterol levels have been established in adults and pediatric patients 9 years of age and older with homozygous familial sitosterolemia. Use of ezetimibe tablets for this indication is based on an 8-week double-blind, placebo-controlled clinical trial in 4 patients 9 years of age and older with homozygous sitosterolemia with elevated plasma sitosterol levels (>5 mg/dL) [ see Clinical Studies (14) ] . The safety and effectiveness of ezetimibe tablets have not been established in pediatric patients younger than 10 years of age with HeFH or HoFH, in pediatric patients younger than 9 years of age with homozygous familial sitosterolemia, or in pediatric patients with other types of hyperlipidemia. 8.5 Geriatric Use Of the 2,396 patients who received ezetimibe tablets in clinical trials, 669 (28%) were 65 years of age and older, and 111 (5%) were 75 years of age and older. Of the 11,308 patients who received ezetimibe tablets in combination with a statin in clinical trials, 3587 (32%) were 65 years of age and older, and 924 (8%) were 75 years of age and older [ see Clinical Studies (14) ] . No overall differences in safety or effectiveness of ezetimibe tablets have been observed between patients 65 years of age and older and younger patients. No clinically meaningful differences in the pharmacokinetics of ezetimibe were observed in geriatric patients compared to younger adult patients [ see Clinical Pharmacology (12.3) ]. 8.6 Renal Impairment No dosage adjustment of ezetimibe tablets is necessary in patients with renal impairment. 8.7 Hepatic Impairment Ezetimibe tablets are not recommended for use in patients with moderate to severe hepatic impairment (Child-Pugh B or C) due to the unknown effects of the increased exposure to ezetimibe [ see Clinical Pharmacology (12.3) ].
