Rimonabant in Abdominally Obese Patients With Impaired Fasting Blood Glucose (PRADO)

A Pan-European Randomized, Parallel Group, Two-arm Placebo-controlled, Double-blind Multicenter Study of Rimonabant 20mg Once Daily in the Treatment of Abdominally Obese Patients With Impaired Fasting Blood Glucose With or Without Other Comorbidities

Primary objective:

To determine the effect of Rimonabant 20mg on the co-primary endpoint including Fasting Plasma Glucose (FPG), HDL-Cholesterol (HDL-C) and triglyceride (TG) levels over a period of 12 months when prescribed with a mild hypocaloric diet in abdominally obese patients with impaired fasting blood glucose and with or without associated comorbidities.

Main Secondary objectives:

To determine the effect of 12 months Rimonabant treatment versus placebo on changes in waist circumference (WC), body weight, glycemic parameters and lipid parameters.

To assess the safety of 12 months Rimonabant treatment versus placebo in these patients.

• Current treatment with statins and/or ezetimibe and/or antihypertensive therapy must be at fixed and stable dose for at least 8 weeks prior to screening visit,
• Patients, who are willing and in the opinion of the Investigator safely assumed to remain on stable and fixed doses of antihypertensive, and/or statins and/or ezetimibe without adding additional medications or changing current treatment for the duration of the trial.

Exclusion Criteria:

• Pregnant or breast-feeding women, or women planning to become pregnant or breastfeed (excluded by pregnancy test),
