Official Title: A Randomized, Double-blind, Stratified, Placebo-controlled, Parallel-group Study of the Efficacy and Safety of the ACAT Inhibitor CS-505 for Reducing the Progression of Atherosclerosis in Subjects With Heterozygous Familial Hypercholesterolemia and Carotid Atherosclerosis Using Carotid Ultrasound (CUS)

Primary Outcome Measures:
  • To demonstrate the effect of pactimibe versus placebo, when added to usual medical care, on the intima-media thickness (IMT) of the carotid arteries in subjects with heterozygous familial hypercholesterolemia (HeFH) and carotid atherosclerosis.

Secondary Outcome Measures:
  • To assess the effects of pactimibe versus placebo, when added to usual medical care:
  • - on the incidence and the time to first occurrence of
  • cardiovascular events,
  • - on inflammatory and oxidative markers, such as serum
  • high-sensitivity C-reactive protein (hsCRP), plasma
  • interleukin 6 (IL-6), plasma myeloperoxidase (MPO) and
  • serum nitrotyrosine.
  • To compare the safety of pactimibe versus placebo, when added to usual medical care, particularly with respect to the incidence of clincal and laboratory adverse events.
