1 JUPITER Justification for the Use of statins in Primary prevention: an Intervention Trial Evaluating Rosuvastatin Ridker P et al. N Eng J Med 2008;359: 2195-2207

2 JUPITER JUPITER is the first large-scale, prospective study to examine the role of statin therapy in individuals with low to normal LDL-C levels, but with increased cardiovascular risk identified by elevated CRP It assessed the long-term impact of rosuvastatin (CRESTOR™) in individuals potentially at increased cardiovascular (CV) risk due to elevated CRP levels who do not qualify for lipid-lowering treatment according to current guidelines Ridker P et al. N Eng J Med 2008;359: 2195-2207

3 JUPITER - Rationale Nearly half of all cardiovascular events occur in patients who are apparently healthy and who have low or normal levels of LDL-C hsCRP predicts cardiovascular disease independent of LDL-C levels Along with improved screening there is a need to examine the use of lipid-lowering agents as a method of reducing the risk of cardiovascular events Ridker PM. New Engl J Med 2002; 347: 1557–1565

26 JUPITER – summary and perspectives The JUPITER study included patients with low to normal LDL-C who were at increased CV risk as identified by elevated CRP levels and who did not require statin treatment based on current treatment guidelines A 44% reduction in the primary endpoint of major cardiovascular events (composite of: CV death, MI, stroke, unstable angina, arterial revascularisation) was observed in patients who received rosuvastatin 20 mg compared with placebo (p< 0.00001) A 20% reduction in total mortality was observed in patients who received rosuvastatin 20 mg compared with placebo (p=0.02), a unique finding for statins in a population without established CHD In JUPITER, long-term treatment with rosuvastatin 20 mg was well tolerated in nearly 9000 study participants There was no difference between treatment groups for muscle weakness, cancer, haematological disorders, gastrointestinal, hepatic or renal systems The results from JUPITER highlight the importance of highly effective statin treatment for these patients with an increased risk of CV disease Ridker P et al.
