  3. Presentation summary Cholesterol and CVD, leading cause of death and high cost Reducing LDL-C levels significantly reduces the risk of CHD Treatment strategies for the cohort of high risk patients Review evidence, clinical trials, clinical practice and NICE Guidance to manage this difficult group of patients

  4. Cardiovascular disease and cholesterol: Key facts • CVD is the leading cause of death in England and Wales1 • The annual cost of managing CVD exceeds £30 billion2 • Over 80% of premature CVD is avoidable2,3 • Reducing CVD risk by 1% over 10 years would prevent 25,000 new cases of CVD4 • Reducing total cholesterol levels by 5% would save the NHS £80 million per annum4 • LDL-C is a key modifiable CVD risk factor1 • NICE targets for secondary prevention of CVD (high risk patients): TC < 4 mmol/L or LDL-C < 2 mmol/L1 • More than 50% of patients will not achieve their target lipid levels on statin therapy alone1 1.

  5. Identifying ‘higher risk’ patients Who are the higher risk patients? • There is a population of patients who are difficult to treat and at increased risk of CVD: • Patients with Type 2 diabetes and established CVD who need to achieve a total cholesterol or an LDL-C of < 4mmol/L and < 2mmol/L, respectively2,3 • Those with familial hypercholesterolaemia requiring > 50% reduction in LDL-C4 1.

  6. Why treat high risk patients? • Patients with T2DM die from complications of their disease • > 70% of patients with T2DM die from cardiovascular causes1 • Patients at high risk of cardiovascular disease have the most to gain from risk factor modification2 • Intensive LDL-C reduction results in significant reductions in cardiovascular morbidity and mortality3 • A 1 mmol/L reduction in LDL-C results in a 22% reduction in the risk of major vascular events4 • The opportunity to improve cardiovascular outcomes by treating atherogenicdyslipidaemia in diabetes (or diabetic patients) should not be missed3 1.

  7. The impact of lowering LDL-C: Lower is better – however you achieve it • For every 1 mmol/L reduction in LDL-C there is a 22% reduction in the risk of major vascular events at 1 year1 • There is a proportional relationship between lowering LDL-C and reducing 5-year non-fatal MI and CHD death risk – irrespective of how LDL-C is lowered2 1 mmol/L 22% 1.

  9. NICE Recommended Levels: LDL-C: 2.0 mmol/L or TC: 4.0 mmol/L What does NICE advise for high risk patients? *MHRA (May 2010) reported increased risk of myopathy with high-dose (80 mg) simvastatin and advised: “Consider only in patients with severe hypercholesterolaemia and high risk of cardiovascular complications who have not achieved their treatment goals on lower doses, when the benefits are expected to outweigh the potential risks.”4 Note: A beneficial effect of EZETROL on cardiovascular morbidity and mortality has not yet been demonstrated • What guidance is available for lowering cholesterol? • Diabetes NICE CG871, FH NICE CG712, Lipids NICE CG673 • Which of these guidelines relate to high risk patients? • Diabetes NICE CG87 • Initiate simvastatin 40 mg, increasing to 80 mg* unlessTC < 4mmol/L or LDL-C < 2mmol/L • Consider intensifying therapy with statin or ezetimibe if existing or new CVD or increased albumin excretion rate • FH NICE CG71 • High intensity statin to achieve a recommended LDL-C reduction of 50% from baseline. Ezetimibe co-administered with a statin (if) target lipid levels are not controlled after dose titration of initial statin, or because titration is limited by intolerance to initial statin 1.

Treating high-risk patients: What are your choices? *MHRA (May 2010) reported increased risk of myopathy with high-dose (80 mg) simvastatin and advised: “Consider only in patients with severe hypercholesterolaemia and high risk of cardiovascular complications who have not achieved their treatment goals on lower doses, when the benefits are expected to outweigh the potential risks.”4 Note: A beneficial effect of EZETROL on cardiovascular morbidity and mortality has not yet been demonstrated 1.

  16. NICE recommendations for treatment with ezetimibe1 “The Committee agreed that there is sufficient evidence to link reductions in LDL cholesterol concentrations induced by treatment with ezetimibe with future reductions in cardiovascular events.”* 1 *Note: A beneficial effect of EZETROL on cardiovascular morbidity and mortality has not yet been demonstrated • Ezetimibe is recommended, as an option, in combination with a statin, when: • Serum total or LDL-C concentration is not appropriately controlled • either after appropriate dose titration of initial statin or • because dose titration is limited by intolerance to the initial statin therapy • You are considering switching from the initial statin therapy • Ezetimibemonotherapy is recommended, as an option, in adults with primary hypercholesterolaemia • who are intolerant to statins, or who are contraindicated for statin therapy 1.

  17. Safety data for ezetimibe1 ALT, alanineaminotransferase; AST, aspartateaminotransferase; CPK, creatinephosphokinase; GGT, gamma-glutamyltransferase Importantly, evidence from 13 randomised, blinded clinical trials in which ezetimibe and simvastatin were administered in combination either as separate or combined tablets (n=4,558) suggests that ezetimibe does not enhance nor aggravate the known muscle effects of simvastatin when compared to simvastatinmonotherapy (n=2,563).2 1.

  18. What NICE says… Patients with Type 2 Diabetes “Consider intensifying cholesterol-lowering therapy (with a more effective statin or ezetimibe in line with NICE guidance) if there is existing or newly diagnosed cardiovascular disease, or if there is an increased albumin excretion rate, to achieve a total cholesterol level below 4.0 mmol/litre (and HDL cholesterol not exceeding 1.4 mmol/litre) or an LDL cholesterol level below 2.0 mmol/litre.” National Institute for Health and Care Excellence. Type 2 Diabetes. Clinical Guideline 87 July 2011. London:NICE. Available from http://guidance.nice.org.uk/CG87. Reproduced with permission

  19. What NICE says…Patients with Familial Hypercholesterolaemia • “Ezetimibe, co-administered with initial statin therapy, is recommended as an option for the treatment of adults with heterozygous-familial hypercholesterolaemia who have been initiated on statin therapy when: • Serum total or LDL-C concentration is not appropriately controlled either after appropriate dose titration of initial statin therapy or because dose titration is limited by intolerance to the initial statin therapy; • and • Consideration is being given to changing from initial statin therapy to an alternative statin.” National Institute for Health and Care Excellence.

  20. In summary: Treating higher risk patients *Note: A beneficial effect of EZETROL on cardiovascular morbidity and mortality has not yet been demonstrated • In secondary prevention patients NICE recommends to consider increasing the statin to simvastatin 80mg, or a drug of similar efficacy and acquisition cost, if TC <4mmol/L or LDL-C<2mmol/L is not attained1 • The evidence indicates that a greater reduction in baseline LDL-C can be achieved by adding ezetimibe to a statin, than by increasing the statin dose,2 or by switching from simvastatin to atorvastatin3 • In patients with CVD, NICE recommends intensified treatment for hypercholesterolaemia.1 In these patients, ezetimibe added to a statin can help more patients achieve NICE-recommended lipid management levels • Reduction in LDL-C, irrespective of how it is achieved, reduces the risk of CVD.4 NICE have accepted there is sufficient evidence to link LDL-C reduction via ezetimibe use with a reduction in future CV events*5 1.
