8 Background Atheroprotective role of high-density lipoprotein cholesterol (HDL-C) Strong inverse relationship between HDL-C levels and cardiovascular events Hypothesis that increasing HDL-C may lead to reduced cardiovascular risks Cholesteryl ester transfer protein (CETP) inhibitors raise HDL-C and decrease LDL-C levels Journal of Lipid Research 2010;51(8):

9 Cholesteryl ester transfer protein (CETP) inhibitors CETP mediates the transfer of cholesterol esters and triglycerides from HDL to LDL CETP inhibition raises HDL-C and reduces LDL-C Clinical Medicine Insights: Cardiology 2016; 10:37-42.

21 Additional Analyses No significant evidence of differential proportional effects with any of 23 prespecified subgroups Patients receiving an ACEi or ARB resulted in a nominal P value for heterogeneity of less than 0.05 N Engl J Med 2017;377(13):

22 Author s Conclusions Addition of anacetrapib at a dose of 100 mg daily to intensive statin therapy for approximately 4 years resulted in a lower incidence of major coronary events than addition of placebo among patients with preexisting atherosclerotic vascular disease

23 Study Strengths Study Design Multicenter, randomized, prospective Sample size of 30,449 Compliance to study medication (13.5% overall) Follow-up for a mean of 4 years

24 Study Limitations LDL cholesterol levels were very well controlled Findings not generalizable to patients with longer term use Only studied patients with preexisting atherosclerotic vascular disease

25 Practice Implications Currently do not anticipate any change in practice Based on evidence from statin trials, the lower non- HDL value in the anacetrapib group could be the basis for the trial results The higher mean HDL cholesterol value in the anacetrapib group does not appear to have as large an impact on coronary events as would be anticipated Price of this medication will further impede it s use Further studies evaluating patients with higher baseline LDL levels currently receiving high dose statin therapy is warranted
