Carotid B-Mode Ultrasound Study to Compare Anti-Atherosclerotic Effect of Torcetrpib/Atorvastatin to Atorvastatin Alone.

Summary

The Torcetrapib project was terminated on December 2, 2006 due to safety findings. To look at ultrasound images taken in the carotid arteries and to look at various lipids in the blood of people with heterozygous familial hypercholesterolemia
