N2 - Context Abdominal obesity is associated with metabolic abnormalities and increased risk of atherosclerotic cardiovascular disease. However, no obesity management strategy has demonstrated the ability to slow progression of coronary disease. Objective To determine whether weight loss and metabolic effects of the selective cannabinoid type 1 receptor antagonist rimonabant reduces progression of coronary disease in patients with abdominal obesity and the metabolic syndrome. Design, Setting, and Patients Randomized, double- blinded, placebo- controlled, 2- group, parallel- group trial ( enrollment December 2004- December 2005) comparing rimonabant with placebo in 839 patients at 112 centers in North America, Europe, and Australia. Interventions Patients received dietary counseling, were randomized to receive rimonabant ( 20 mg daily) or matching placebo, and underwent coronary intravascular ultrasonography at baseline ( n= 839) and study completion ( n= 676). Main Outcome Measures The primary efficacy parameter was change in percent atheroma volume ( PAV); the secondary efficacy parameter was change in normalized total atheroma volume ( TAV). Results In the rimonabant vs placebo groups, PAV ( 95% confidence interval [ CI]) increased 0.25% (- 0.04% to 0.54%) vs 0.51% ( 0.22% to 0.80%) ( P=. 22), respectively, and TAV decreased 2.2 mm(3) (- 4.09 to - 0.24) vs an increase of 0.88 mm(3) (- 1.03 to 2.79) ( P=. 03). In the rimonabant vs placebo groups, imputingresultsbasedonbaselinecharacteristics for patients not completing the trial, PAV increased 0.25% (- 0.04% to 0.55%) vs 0.57% ( 0.29% to 0.84%) ( P=. 13), and TAV decreased 1.95 mm(3) (- 3.8 to - 0.10) vs an increase of 1.19 mm(3) (- 0.73 to 3.12) ( P=. 02). Rimonabant- treated patients had a larger reduction in body weight ( 4.3 kg [- 5.1 to - 3.5] vs 0.5 kg [- 1.3 to 0.3]) and greater decrease in waist circumference ( 4.5 cm [- 5.4 to - 3.7] vs 1.0 cm [- 1.9 to - 0.2]) ( P <. 001 for both comparisons). In the rimonabant vs placebo groups, high- density lipoprotein cholesterol levels increased 5.8 mg/dL( 4.9 to 6.8) ( 22.4%) vs 1.8 mg/ dL( 0.9 to 2.7) ( 6.9%) ( P <. 001), and median triglyceride levels decreased 24.8mg/ dL(- 35.4 to - 17.3) ( 20.5%) vs 8.9 mg/ dL (- 14.2 to - 1.8) ( 6.2%) ( P <. 001). Rimonabant- treated patients had greater decreases in high- sensitivity C- reactive protein ( 1.3 mg/ dL[- 1.7 to - 1.2] [ 50.3%] vs 0.9 mg/ dL[- 1.4 to - 0.5][ 30.9%]) and less increase in glycated hemoglobin levels( 0.11%[ 0.02% to 0.20%] vs 0.40% [ 0.31% to 0.49%]) ( P <. 001 for both comparisons). Psychiatric adverse effects were more common in the rimonabant group ( 43.4% vs 28.4%, P <. 001). Conclusions After 18 months of treatment, the study failed to show an effect for rimonabant on disease progression for the primary end point ( PAV) but showed a favorable effect on the secondary end point ( TAV). Determining whether rimonabant is useful in management of coronary disease will require additional imaging and outcomes trials, which are currently under way.
