1 Clinical Trial Results. org ILLUSTRATE Presented at the American College of Cardiology Annual Scientific Session March, 2007 Presented by Dr. Steven E. Nissen Investigation of Lipid Level Management Using Coronary Ultrasound to Assess Reduction of Atherosclerosis by CETP Inhibition and HDL Elevation

2 Clinical Trial Results. org ILLUSTRATE Trial: Background The goal of the trial was to evaluate the effect of treatment with torcetrapib, a cholesteryl ester transfer protein (CETP) inhibitor, in addition to atorvastatin as compared with atorvastatin treatment alone on disease progression among patients with coronary artery disease.The goal of the trial was to evaluate the effect of treatment with torcetrapib, a cholesteryl ester transfer protein (CETP) inhibitor, in addition to atorvastatin as compared with atorvastatin treatment alone on disease progression among patients with coronary artery disease.

7 Clinical Trial Results. org ILLUSTRATE Trial: Limitations Commercial development of torcetrapib was recently stopped after a large trial showed an increase in mortality with torcetrapib, along with an increase in blood pressure.Commercial development of torcetrapib was recently stopped after a large trial showed an increase in mortality with torcetrapib, along with an increase in blood pressure. The present trial, while much smaller than the other trial, did not show a difference in mortality with torcetrapib, but there were only 14 deaths.The present trial, while much smaller than the other trial, did not show a difference in mortality with torcetrapib, but there were only 14 deaths.
