Brief Summary:


  • Primary: To evaluate the effect of rimonabant 20-mg once daily in comparison with placebo, on the quantitative progression of atherosclerosis as assessed by carotid artery intima-media thickness (CIMT)
  • Secondary: To evaluate the safety and tolerability of the above rimonabant regimen in the study population of atherosclerosis patients.

Condition or disease Intervention/treatment Phase
Carotid Artery Plaque Arteriosclerosis Obesity Metabolic Syndrome X Drug: Rimonabant Drug: Placebo (for Rimonabant) Phase 3

Detailed Description:
This is a Phase III, prospective, multicentre, multinational, randomized, double-blind, placebo-controlled, 2-arm parallel group trial (rimonabant 20-mg od vs placebo). There will be a three-stage screening process including successively a Screening visit, a Screening CIMT and a validation of the Screening CIMT by the Imaging Core Laboratory. Patients complying with all inclusion and exclusion criteria will be randomized in one of the 2 treatment groups less than two weeks after Screening visit. Study drug (rimonabant 20 mg od or matching placebo) will be administered during 30 to 32 months. At inclusion, patients will be counseled to follow a mild hypocaloric diet, to increase their exercise level, and to stop smoking (if smokers). Glucose/lipid parameters will be assessed at Baseline and every 6 months until the Month 30 visit. CIMT will be performed at Baseline and every 6 months until final assessment at Month 30 (primary endpoint).A post-treatment follow-up visit at Month 35 will allow the collection of all adverse events and cardiovascular outcomes occurring after last study drug administration

  • Ultrasonographic evidence at Screening quantitative B-mode ultrasound imaging of a minimal CIMT measurement of greater than or equal to 0.7 mm in either of the far walls of the common carotid artery, and maximal CIMT measurement less than 3 mm in any carotid artery segment.
