Rimonabant in Obesity Over a 2-Year Duration (RIO-Europe)

Summary

The primary objective was to assess the effect of SR141716 on weight loss and weight maintenance over a period of one year when prescribed with a hypocaloric diet in obese patients with or without comorbidities. The main secondary objectives were to assess the effect of SR141716 on lipid parameters (HDL-C, TG), glucose tolerance status, the rate of patients with metabolic syndrome, waist circumference, glycemic parameters.
