1 Latest Insights from the JUPITER Study John J.P. Kastelein MD PhD Professor of Medicine Dept. of Vascular Medicine Academic Medial Center / University of Amsterdam

2 Inflammation, hscrp, and Vascular Prevention Is there evidence that individuals with elevated levels of the inflammatory biomarker hscrp are at high vascular risk even when other risk factors are acceptable? Is there evidence that individuals identified at increased risk due to inflammation benefit from a therapy they otherwise would not have received? Should our guidelines for vascular disease prevention change?

4 The net reclassification improvement when CRP was added to traditional risk factors was 11.8 % for hard CHD (P=0.009), a value greater than that of LDL, HDL, or blood pressure in the Framingham Data Wilson P, et al Circ Cardiovasc Qual Outcomes 2008;1:92-97

5 Meta-analysis of 54 Prospective Cohort Studies: The magnitude of independent risk associated with hscrp is at least as large, if not larger, than that of BP and cholesterol Risk Ratio (95%CI) hscrp Systolic BP Total cholesterol Non-HDLC 1.37 ( ) 1.35 ( ) 1.16 ( ) 1.28 ( ) Risk Ratio (95%CI) per 1-SD higher usual values Adjusted for age, gender, smoking, diabetes, BMI, triglycerides, alcohol, lipid levels, and hscrp Emerging Risk Factor Collaborators, Lancet January 2010 CR-5

6 Inflammation, hscrp, and Vascular Prevention Is there evidence that individuals with elevated levels of the inflammatory biomarker hscrp are at high vascular risk even when other risk factors are acceptable? Is there evidence that individuals identified at increased risk due to inflammation benefit from a therapy they otherwise would not have received? Should our guidelines for vascular disease prevention change?

21 Inflammation, hscrp, and Vascular Prevention Is there evidence that individuals with elevated levels of the inflammatory biomarker hscrp are at high vascular risk even when other risk factors are acceptable? Is there evidence that individuals identified at increased risk due to inflammation benefit from a therapy they otherwise would not have received? Should our guidelines for vascular disease prevention change?

22 2009 Canadian Cardiovascular Society (CCS) Guidelines for the Diagnosis and Treatment of Dyslipidemia and Prevention of Cardiovascular Disease in the Adult Primary Goal : LDLC High CAD, CVA, PVD <2mmol/L or 50% reduction Class I Most pts with Diabetes Level A FRS > 20 % RRS > 20 % Moderate FRS % <2mmol/L or 50 % reduction Class IIA RRS % Level A LDL > 3.5 mmol/l TC/HDLC > 5.0 hscrp > 2 in men >50 yr women > 60 yr Low FRS < 10 % <5mmol/L Class IIA Level A Secondary Targets : TC/HDLC < 4, non HDLC < 3.5 mol/l, hscrp < 2 mg/l, TG < 1.7 mol/l, ApoB/A<0.8 CR-22

23 JUPITER Achieved LDLC, Achieved hscrp, or Both? LDL (mg/dl) hscrp (mg/l) LDL decrease 50 percent at 12 months Is the large benefit observed in the JUPITER trial due to lipid lowering, to inflammation inhibition, or to a combination of these two processes? hscrp decrease 37 percent at 12 months Months

24 JUPITER: Future RCT s on top of statin therapy with MTX, IL1B agonists, Romiflulast and other anti inflammatory agents will determine whether we were right or wrong
