  Purpose

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

Criteria

Inclusion Criteria:

  • Diagnosis of Heterozygous Familial Hypercholesterolemia
  • At least 18 years of age

Exclusion Criteria:

  • Women who are pregnant or lactating, or planning to become pregnant.
  • Subjects with a clinically indicated need for statin (HMG-CoA reductase inhibitor) therapy other than atorvastatin or other concomitant therapy with known lipid altering effects on LDL-C and HDL-C including fibrates and nicotinic acid (high doses)
  • Subjects taking any drugs known to be associated with an increased risk of myositis in combination with HMG-CoA reductase inhibitors
  • Subjects with any other medical condition or laboratory abnormality which could affect subject safety, preclude evaluationof response, or render unlikely that the subject would complete the study
