Title: Effects of Rimonabant on Metabolic Risk Factors in Overweight Patients with Dyslipidemia
Authors: Després J-P, Golay A, Sjöström L, for the Rimonabant in Obesity-Lipids Study Group
Journal: N Engl J Med 2005;353:2121–34
Objective
To study the effects of rimonabant on metabolic risk factors, including adiponectin levels, in high-risk patients who are overweight or obese and have untreated dyslipidemia Design
› Randomized, double-blind, placebo-controlled, multicenter study › Patients randomized to receive placebo, rimonabant 5 mg, or rimonabant 20 mg (1:1:1 ratio, › Single blind, 4-week placebo run-in period with mildly hypocaloric diet (600 kcal/day deficit) that Patient Population
› Presence of untreated dyslipidemia: triglycerides > 150–700 mg/dL (1.69–7.90 mmol/L), or ratio of cholesterol to high-density lipoprotein cholesterol (HDL-C) of > 4.5 in women and > 5 in men Endpoints
› Primary: Change in body weight › Secondary: Changes in levels of HDL-C, triglycerides, glucose, insulin (during an oral glucose tolerance test), metabolic syndrome, waist circumference, leptin, adiponectin, and relevant biochemical cardiovascular markers (for example, C-reactive protein); and assessment of safety Results
› Weight change: Rimonabant 20 mg induced significant weight loss compared with placebo: -19 lb (-8.6 kg) rimonabant 20 mg vs. -5.1 lb (-2.3 kg) placebo using the repeated-measures (RM) model for completers (which provided a better estimate of the true effect of the drug than last observation carried forward [LOCF]); with the LOCF analysis, weight loss was -15.2 lb (-6.9 kg) rimonabant 20 mg vs. -3.3 lb (-1.5 kg) placebo (P < 0.001) FOR SALES EDUCATION ONLY. NOT FOR PROMOTIONAL USE. DO NOT DUPLICATE, DISTRIBUTE, OR USE IN DETAILING.
Rimonabant
› Waist circumference: Rimonabant 20 mg induced a significant decrease in waist circumference compared with placebo: -9.1 cm with rimonabant 20 mg vs. -3.4 cm with placebo (P < 0.001) using RM; and -7.1 cm vs. -2.4 cm using LOCF › Triglycerides: Levels decreased -15.8% with rimonabant 20 mg vs. -3.6% with placebo (P < 0.001) using RM; -12.6 vs. -0.2 using LOCF › HDL-C: Levels increased 23.4% with rimonabant 20 mg vs. 12.2% with placebo (P < 0.001) using › Plasma adiponectin: Levels of plasma adiponectin increased by 57.7% with rimonabant 20 mg using RM and 46.2% using LOCF (P < 0.001), a change that was partly independent of weight loss › Other factors: Rimonabant 20 mg also showed significant improvement over placebo in changes in low-density lipoprotein particle size, glucose tolerance, fasting and post-challenge insulin levels, C-reactive protein levels, and the proportion of patients with metabolic syndrome › Safety profile: The rates of completion for the study were similar among those receiving placebo and rimonabant 5 mg and 20 mg. The most frequent adverse events causing discontinuation were depression, anxiety, and nausea Conclusions
› CB1-receptor blockade with rimonabant significantly reduces body weight and waist circumference and improves a number of metabolic risk factors in overweight or obese patients who have atherogenic dyslipidemia › The adverse-event profile in this study was similar to that in the RIO-Europe study › The weight-loss-independent effect of rimonabant on plasma adiponectin levels is consistent with rimonabant’s in vitro effect on adiponectin production by adipocytes FOR SALES EDUCATION ONLY.
