Homozygous sitosterolaemia (phytosterolaemia)



'Ezetrol' is indicated as adjunctive therapy to diet for use in patients with homozygous familial sitosterolaemia.



A beneficial effect of Ezetrol on cardiovascular morbidity and mortality has not yet been demonstrated.



4.2 Posology And Method Of Administration



The patient should be on an appropriate lipid



Route of administration is oral. The recommended dose is one 'Ezetrol' 10 mg tablet daily. 'Ezetrol' can be administered at any time of the day, with or without food.



When 'Ezetrol' is added to a statin, either the indicated usual initial dose of that particular statin or the already established higher statin dose should be continued. In this setting, the dosage instructions for that particular statin should be consulted.



Co-administration with bile acid sequestrants



Dosing of 'Ezetrol' should occur either



Use in the elderly



No dosage adjustment is required for elderly patients (see section 5.2).



Use in paediatric patients



Initiation of treatment must be performed under review of a specialist.



Adolescents



When Ezetrol is administered with simvastatin, the dosage instructions for simvastatin, in adolescents should be consulted.



Children <10 years: 'Ezetrol' is not recommended for use in children below age 10 due to insufficient data on safety and efficacy (see section 5.2).



Use in hepatic impairment



No dosage adjustment is required in patients with mild hepatic insufficiency (Child Pugh score 5 to 6). Treatment with 'Ezetrol' is not recommended in patients with moderate (Child Pugh score 7 to 9) or severe (Child Pugh score>9) liver dysfunction. (See sections 4.4 and 5.2.)



Use in renal impairment



No dosage adjustment is required for renally impaired patients (see section 5.2).



4.3 Contraindications



Hypersensitivity to the active substance or to any of the excipients.



When 'Ezetrol' is co-administered with a statin, please refer to the SPC for that particular medicinal product.



Therapy with 'Ezetrol' co-administered with a statin is contraindicated during pregnancy and lactation.



'Ezetrol' co-administered with a statin is contraindicated in patients with active liver disease or unexplained persistent elevations in serum transaminases.



4.4 Special Warnings And Precautions For Use



When 'Ezetrol' is co-administered with a statin, please refer to the SPC for that particular medicinal product.



Liver enzymes



In controlled co-administration trials in patients receiving 'Ezetrol' with a statin, consecutive transaminase elevations (



Skeletal muscle



In post-marketing experience with 'Ezetrol', cases of myopathy and rhabdomyolysis have been reported. Most patients who developed rhabdomyolysis were taking a statin concomitantly with 'Ezetrol'. However, rhabdomyolysis has been reported very rarely with 'Ezetrol' monotherapy and very rarely with the addition of 'Ezetrol' to other agents known to be associated with increased risk of rhabdomyolysis. If myopathy is suspected based on muscle symptoms or is confirmed by a creatine phosphokinase (CPK) level>10 times the ULN, 'Ezetrol', any statin, and any of these other agents that the patient is taking concomitantly should be immediately discontinued. All patients starting therapy with 'Ezetrol' should be advised of the risk of myopathy and told to report promptly any unexplained muscle pain, tenderness or weakness (see section 4.8).



Hepatic insufficiency



Due to the unknown effects of the increased exposure to ezetimibe in patients with moderate or severe hepatic insufficiency, 'Ezetrol' is not recommended (see section 5.2).



Paediatric (10 to 17 Years of Age) Patients



Efficacy and safety of Ezetrol co-administered with simvastatin in patients 10 to 17 years of age with heterozygous familial hypercholesterolemia have been evaluated in a controlled clinical trial in adolescent boys (Tanner stage II or above) and in girls who were at least one year post-menarche.



In this limited controlled study, there was generally no detectable effect on growth or sexual maturation in the adolescent boys or girls, or any effect on menstrual cycle length in girls. However, the effects of ezetimibe for a treatment period> 33 weeks on growth and sexual maturation have not been studied (see sections 4.2 and 4.8)



The safety and efficacy of Ezetrol co-administered with doses simvastatin above 40mg daily have not been studied in paediatric patients 10 to 17 years of age.



Ezetrol has not been studied in patients younger than 10 years of age or in pre-menarchal girls. (See sections 4.2 and 4.8.)



The long-term efficacy of therapy with Ezetrol in patients below 17 years of age to reduce morbidity and mortality in adulthood has not been studied.



Fibrates



The safety and efficacy of 'Ezetrol' administered with fibrates have not been established.



If cholelithiasis is suspected in a patient receiving 'Ezetrol' and fenofibrate, gallbladder investigations are indicated and this therapy should be discontinued (see sections 4.5 and 4.8).



Ciclosporin



Caution should be exercised when initiating 'Ezetrol' in the setting of ciclosporin. Ciclosporin concentrations should be monitored in patients receiving 'Ezetrol' and ciclosporin (see section 4.5).



Anticoagulants



If 'Ezetrol' is added to warfarin, another coumarin anticoagulant, or fluindione, the International Normalised Ratio (INR) should be appropriately monitored (see section 4.5).



Excipient



Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



Interaction studies have only been performed in adults.



In preclinical studies, it has been shown that ezetimibe does not induce cytochrome P450 drug metabolising enzymes. No clinically significant pharmacokinetic interactions have been observed between ezetimibe and drugs known to be metabolised by cytochromes P450 1A2, 2D6, 2C8, 2C9, and 3A4, or N-acetyltransferase.



In clinical interaction studies, ezetimibe had no effect on the pharmacokinetics of dapsone, dextromethorphan, digoxin, oral contraceptives (ethinyl estradiol and levonorgestrel), glipizide, tolbutamide, or midazolam, during co-administration. Cimetidine, co-administered with ezetimibe, had no effect on the bioavailability of ezetimibe.



Antacids: Concomitant antacid administration decreased the rate of absorption of ezetimibe but had no effect on the bioavailability of ezetimibe. This decreased rate of absorption is not considered clinically significant.



Colestyramine: Concomitant colestyramine administration decreased the mean area under the curve (AUC) of total ezetimibe (ezetimibe + ezetimibe glucuronide) approximately 55%. The incremental low



Fibrates: In patients receiving fenofibrate and 'Ezetrol', physicians should be aware of the possible risk of cholelithiasis and gallbladder disease (see section 4.4 and 4.8).



If cholelithiasis is suspected in a patient receiving 'Ezetrol' and fenofibrate, gallbladder investigations are indicated and this therapy should be discontinued (see section 4.8).



Concomitant fenofibrate or gemfibrozil administration modestly increased total ezetimibe concentrations (approximately 1.5- and 1.7-fold respectively).



Co-administration of 'Ezetrol' with other fibrates has not been studied.



Fibrates may increase cholesterol excretion into the bile, leading to cholelithiasis. In animal studies, ezetimibe sometimes increased cholesterol in the gallbladder bile, but not in all species (see section 5.3). A lithogenic risk associated with the therapeutic use of 'Ezetrol' cannot be ruled out.



Statins: No clinically significant pharmacokinetic interactions were seen when ezetimibe was co-administered with atorvastatin, simvastatin, pravastatin, lovastatin, fluvastatin or rosuvastatin.



Ciclosporin: In a study of eight post-renal transplant patients with creatinine clearance of>50 ml/min on a stable dose of ciclosporin, a single 10-mg dose of 'Ezetrol' resulted in a 3.4-fold (range 2.3 to 7.9-fold) increase in the mean AUC for total ezetimibe compared to a healthy control population, receiving ezetimibe alone, from another study (n=17). In a different study, a renal transplant patient with severe renal insufficiency who was receiving ciclosporin and multiple other medications, demonstrated a 12-fold greater exposure to total ezetimibe compared to concurrent controls receiving ezetimibe alone. In a two-period crossover study in 12 healthy subjects, daily administration of 20 mg ezetimibe for 8 days with a single 100



Anticoagulants: Concomitant administration of ezetimibe (10 mg once daily) had no significant effect on bioavailability of warfarin and prothrombin time in a study of twelve healthy adult males. However, there have been post-marketing reports of increased International Normalised Ratio (INR) in patients who had 'Ezetrol' added to warfarin or fluindione. If 'Ezetrol' is added to warfarin, another coumarin anticoagulant, or fluindione, INR should be appropriately monitored (see Section 4.4).



4.6 Pregnancy And Lactation



'Ezetrol' co-administered with a statin is contraindicated during pregnancy and lactation (see section 4.3), please refer to the SPC for that particular statin.



Pregnancy:



'Ezetrol' should be given to pregnant women only if clearly necessary. No clinical data are available on the use of 'Ezetrol' during pregnancy. Animal studies on the use of ezetimibe in monotherapy have shown no evidence of direct or indirect harmful effects on pregnancy, embryofoetal development, birth or postnatal development (see section 5.3).



Lactation:



'Ezetrol' should not be used during lactation. Studies on rats have shown that ezetimibe is secreted into breast milk. It is not known if ezetimibe is secreted into human breast milk.



4.7 Effects On Ability To Drive And Use Machines



No studies on the effects on the ability to drive and use machines have been performed. However, when driving vehicles or operating machines, it should be taken into account that dizziness has been reported.



4.8 Undesirable Effects



Clinical Studies



In clinical studies of up to 112 weeks duration, 'Ezetrol' 10 mg daily was administered alone in 2396 patients, or with a statin in 11,308 patients or with fenofibrate in 185 patients. Adverse reactions were usually mild and transient. The overall incidence of side effects was similar between 'Ezetrol' and placebo. Similarly, the discontinuation rate due to adverse experiences was comparable between 'Ezetrol' and placebo.



'Ezetrol' administered alone or co-administered with a statin:



The following adverse reactions were observed in patients treated with 'Ezetrol' (N=2396) and at a greater incidence than placebo (N=1159) or in patients treated with 'Ezetrol' co-administered with a statin (N=11308) and at a greater incidence than statin administered alone (N=9361):

Gastrointestinal disorders: abdominal pain (common).



In a multicentre, double-blind, placebo-controlled, clinical study in patients with mixed hyperlipidaemia, 625 patients were treated for up to 12 weeks and 576 patients for up to 1 year. In this study, 172 patients treated with 'Ezetrol' and fenofibrate completed 12 weeks of therapy, and 230 patients treated with 'Ezetrol' and fenofibrate (including 109 who received 'Ezetrol' alone for the first 12 weeks) completed 1 year of therapy. This study was not designed to compare treatment groups for infrequent events. Incidence rates (95% CI) for clinically important elevations (>3 X ULN, consecutive) in serum transaminases were 4.5% (1.9, 8.8) and 2.7% (1.2, 5.4) for fenofibrate monotherapy and 'Ezetrol' co-administered with fenofibrate, respectively, adjusted for treatment exposure. Corresponding incidence rates for cholecystectomy were 0.6% (0.0, 3.1) and 1.7% (0.6, 4.0) for fenofibrate monotherapy and 'Ezetrol' co-administered with fenofibrate, respectively (see sections 4.4 and 4.5).



Paediatric (10 to 17 years of age) Patients



In a study involving adolescent (10 to 17 years of age) patients with heterozygous familial hypercholesterolaemia (n = 248), elevations of ALT and/or AST (



This trial was not suited for comparison of rare adverse drug reactions.



Laboratory values



In controlled clinical monotherapy trials, the incidence of clinically important elevations in serum transaminases (ALT and/or AST



In clinical trials, CPK>10 X ULN was reported for 4 of 1,674 (0.2%) patients administered 'Ezetrol' alone vs 1 of 786 (0.1%) patients administered placebo, and for 1 of 917 (0.1%) patients co-administered 'Ezetrol' and a statin vs 4 of 929 (0.4%) patients administered a statin alone. There was no excess of myopathy or rhabdomyolysis associated with 'Ezetrol' compared with the relevant control arm (placebo or statin alone). (See section 4.4.)



Post-marketing Experience



The following additional adverse reactions have been reported in post-marketing experience. Because these adverse experiences have been identified from spontaneous reports, their true frequencies are not known and cannot be estimated.



Blood and lymphatic system disorders: thrombocytopenia



Nervous system disorders: dizziness; paraesthesia



Respiratory, thoracic and mediastinal disorders: dyspnoea



Gastro-intestinal disorders: pancreatitis; constipation



Skin and subcutaneous tissue disorders: erythema multiforme



Musculoskeletal and connective tissue disorders: myalgia; myopathy/rhabdomyolysis (see section 4.4).



General disorders and administration site conditions: asthenia



Immune system disorders: hypersensitivity, including rash, urticaria, anaphylaxis and angioedema



Hepatobiliary disorders: hepatitis, cholelithiasis, cholecystitis



Psychiatric disorders: depression.



4.9 Overdose



In clinical studies, administration of ezetimibe, 50 mg/day, to 15 healthy subjects for up to 14 days, or 40 mg/day to 18 patients with primary hypercholesterolaemia for up to 56 days, was generally well tolerated. In animals, no toxicity was observed after single oral doses of 5,000 mg/kg of ezetimibe in rats and mice and 3,000 mg/kg in dogs.



A few cases of overdosage with 'Ezetrol' have been reported: most have not been associated with adverse experiences. Reported adverse experiences have not been serious. In the event of an overdose, symptomatic and supportive measures should be employed.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



Pharmacotherapeutic group: Other lipid modifying agents. ATC code: C10A X09



'Ezetrol' is in a new class of lipid-lowering compounds that selectively inhibit the intestinal absorption of cholesterol and related plant sterols. 'Ezetrol' is orally active, and has a mechanism of action that differs from other classes of cholesterol



Ezetimibe localises 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; statins reduce cholesterol synthesis in the liver and together these distinct mechanisms provide complementary cholesterol reduction. In a 2



A series of 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 fat soluble vitamins A and D.



Epidemiologic studies have established that cardiovascular morbidity and mortality vary directly with the level of total



CLINICAL TRIALS



In controlled clinical studies, 'Ezetrol', either as monotherapy or co-administered with a statin significantly reduced total cholesterol (total



Primary hypercholesterolaemia



In a double-blind, placebo-controlled, 8-week study, 769 patients with hypercholesterolaemia already receiving statin monotherapy and not at National Cholesterol Education Program (NCEP) LDL



Among statin-treated patients not at LDL



In two, double-blind, randomised placebo-controlled, 12-week studies in 1,719 patients with primary hypercholesterolaemia, 'Ezetrol' 10 mg significantly lowered total



In a multicenter, double-blind, controlled clinical study (ENHANCE), 720 patients with heterozygous familial hypercholesterolemia were randomized to receive ezetimibe 10 mg in combination with simvastatin 80 mg (n = 357) or simvastatin 80 mg (n = 363) for 2 years. The primary objective of the study was to investigate the effect of ezetimibe/simvastatin combination therapy on carotid artery intima-media thickness (IMT) compared to simvastatin monotherapy. The impact of this surrogate marker on cardiovascular morbidity and mortality is still not demonstrated.



The primary endpoint, the change in the mean IMT of all six carotid segments, did not differ significantly (p=0.29) between the two treatment groups as measured by B-mode ultrasound. With ezetimibe 10 mg in combination with simvastatin 80 mg or simvastatin 80 mg alone, intima-medial thickening increased by 0.0111 mm and 0.0058 mm, respectively, over the study's 2 year duration (baseline mean carotid IMT 0.68 mm and 0.69 mm respectively).



Ezetimibe 10 mg in combination with simvastatin 80 mg lowered LDL-C, total-C, Apo B, and TG significantly more than simvastatin 80 mg. The percent increase in HDL-C was similar for the two treatment groups. The adverse reactions reported for ezetimibe 10 mg in combination with simvastatin 80 mg were consistent with its known safety profile.



Clinical Studies in Paediatric Patients (10 to 17 years of age)



In a multicentre, double-blind, controlled study, 142 boys (Tanner stage II and above) and 106 postmenarchal girls, 10 to 17 years of age (mean age 14.2 years) with heterozygous familial hypercholesterolaemia (HeFH) with baseline LDL-C levels between 4.1 and 10.4 mmol/l were randomised to either Ezetrol 10 mg co-administered with simvastatin (10, 20 or 40 mg) or simvastatin (10, 20 or 40 mg) alone for 6 weeks, co-administered Ezetrol and 40 mg simvastatin or 40 mg simvastatin alone for the next 27 weeks, and open-label co-administered Ezetrol and simvastatin (10 mg, 20 mg, or 40 mg) for 20 weeks thereafter.



At Week 6, Ezetrol co-administered with simvastatin (all doses) significantly reduced total-C (38 % vs 26 %), LDL-C (49 % vs 34 %), Apo B (39 % vs 27 %), and non-HDL-C (47 % vs 33 %) compared to simvastatin (all doses) alone. Results for the two treatment groups were similar for TG and HDL-C (



The safety and efficacy of Ezetrol co-administered with doses of simvastatin above 40 mg daily have not been studied in paediatric patients 10 to 17 years of age. The long-term efficacy of therapy with Ezetrol in patients below 17 years of age to reduce morbidity and mortality in adulthood has not been studied.



Homozygous Familial Hypercholesterolaemia (HoFH)



A double



Homozygous sitosterolaemia (phytosterolaemia)



In a double-blind, placebo-controlled, 8-week trial, 37 patients with homozygous sitosterolaemia were randomised to receive 'Ezetrol' 10 mg (n=30) or placebo (n=7). Some patients were receiving other treatments (e.g. statins, resins). 'Ezetrol' significantly lowered the two major plant sterols, sitosterol and campesterol, by 21% and 24% from baseline, respectively. The effects of decreasing sitosterol on morbidity and mortality in this population are not known.



Aortic Stenosis



The Simvastatin and Ezetimibe for the Treatment of Aortic Stenosis (SEAS) study was a multi-center, double-blind, placebo-controlled study with a median duration of 4.4 years conducted in 1873 patients with asymptomatic aortic stenosis (AS), documented by Doppler-measured aortic peak flow velocity within the range of 2.5 to 4.0 m/s. Only patients who were considered not to require statin treatment for purposes of reducing atherosclerotic cardiovascular disease risk were enrolled. Patients were randomized 1:1 to receive placebo or co-administered ezetimibe 10 mg and simvastatin 40 mg daily.



The primary endpoint was the composite of major cardiovascular events (MCE) consisting of cardiovascular death, aortic valve replacement (AVR) surgery, congestive heart failure (CHF) as a result of progression of AS, nonfatal myocardial infarction, coronary artery bypass grafting (CABG), percutaneous coronary intervention (PCI), hospitalization for unstable angina, and nonhemorrhagic stroke. The key secondary endpoints were composites of subsets of the primary endpoint event categories.



Compared to placebo, ezetimibe/simvastatin 10/40 mg did not significantly reduce the risk of MCE. The primary outcome occurred in 333 patients (35.3%) in the ezetimibe / simvastatin group and in 355 patients (38.2%) in the placebo group (hazard ratio in the ezetimibe / simvastatin group, 0.96; 95% confidence interval, 0.83 to 1.12; p = 0.59). Aortic valve replacement was performed in 267 patients (28.3%) in the ezetimibe / simvastatin group and in 278 patients (29.9%) in the placebo group (hazard ratio, 1.00; 95% CI, 0.84 to 1.18; p = 0.97). Fewer patients had ischemic cardiovascular events in the ezetimibe / simvastatin group (n=148) than in the placebo group (n=187) (hazard ratio, 0.78; 95% CI, 0.63 to 0.97; p = 0.02), mainly because of the smaller number of patients who underwent coronary artery bypass grafting.



Cancer occurred more frequently in the ezetimibe / simvastatin group (105 versus 70, p=0.01). The clinical relevance of this observation is uncertain. In a meta-analysis including interim results from two large, long-term, ongoing studies with ezetimibe / simvastatin (n=10,319 actively treated, 10,298 control treated; patient-years = 18,246 actively treated, 18,255 control treated) there was not an increased rate of cancer (313 active treatment, 326 control; risk ratio, 0.96; 0.95% confidence interval, 0.82 to 1.12; p=0.61).



5.2 Pharmacokinetic Properties



Absorption: After oral administration, ezetimibe is rapidly absorbed and extensively conjugated to a pharmacologically-active phenolic glucuronide (ezetimibe-glucuronide). Mean maximum plasma concentrations (Cmax) occur within 1 to 2 hours for ezetimibe-glucuronide and 4 to 12 hours for ezetimibe. The absolute bioavailability of ezetimibe cannot be determined as the compound is virtually insoluble in aqueous media suitable for injection.



Concomitant food administration (high fat or non-fat meals) had no effect on the oral bioavailability of ezetimibe when administered as 'Ezetrol' 10



Distribution: Ezetimibe and ezetimibe



Biotransformation: Ezetimibe is metabolised primarily in the small intestine and liver via glucuronide conjugation (a phase II reaction) with subsequent biliary excretion. Minimal oxidative metabolism (a phase I reaction) has been observed in all species evaluated. 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 slowly eliminated from plasma with evidence of significant enterohepatic recycling. The half-life for ezetimibe and ezetimibe-glucuronide is approximately 22 hours.



Elimination: Following oral administration of 14C



Special populations:



Paediatric patients



The absorption and metabolism of ezetimibe are similar between children and adolescents (10 to 18 years) and adults. Based on total ezetimibe, there are no pharmacokinetic differences between adolescents and adults. Pharmacokinetic data in the paediatric population <10 years of age are not available. Clinical experience in paediatric and adolescent patients includes patients with HoFH, HeFH, or sitosterolaemia.



Geriatric patients



Plasma concentrations for total ezetimibe are about 2

After a single 102), the mean AUC for total ezetimibe was increased approximately 1.5



An additional patient in this study (post-renal transplant and receiving multiple medications, including ciclosporin) had a 12



Gender



Plasma concentrations for total ezetimibe are slightly higher (approximately 20%) in women than in men. LDL



5.3 Preclinical Safety Data



Animal studies on the chronic toxicity of ezetimibe identified no target organs for toxic effects. In dogs treated for four weeks with ezetimibe (



In co-administration studies with ezetimibe and statins the toxic effects observed were essentially those typically associated with statins. Some of the toxic effects were more pronounced than observed during treatment with statins alone. This is attributed to pharmacokinetic and pharmacodynamic interactions in co-administration therapy. No such interactions occurred in the clinical studies. Myopathies occurred in rats only after exposure to doses that were several times higher than the human therapeutic dose (approximately 20 times the AUC level for statins and 500 to 2,000 times the AUC level for the active metabolites).



In a series of in vivo and in vitro assays ezetimibe, given alone or co-administered with statins, exhibited no genotoxic potential. Long-term carcinogenicity tests on ezetimibe were negative.



Ezetimibe had no effect on the fertility of male or female rats, nor was it found to be teratogenic in rats or rabbits, nor did it affect prenatal or postnatal development. Ezetimibe crossed the placental barrier in pregnant rats and rabbits given multiple doses of 1,000 mg/kg/day. The co-administration of ezetimibe and statins was not teratogenic in rats. In pregnant rabbits a small number of skeletal deformities (fused thoracic and caudal vertebrae, reduced number of caudal vertebrae) were observed. The co-administration of ezetimibe with lovastatin resulted in embryolethal effects.
