VICTORIA: VIsceral Fat Reduction Assessed by CT-scan On RImonabAnt
Study Details
Study Description
Brief Summary
Primary objective:
To assess the effect of rimonabant on visceral fat area over a period of 12 months when prescribed with a mild hypocaloric diet in abdominally obese patients with metabolic syndrome
Secondary objectives:
-
To assess the effect of rimonabant over a period of 12 months on:
-
Liver fat content using CT scan (Computed Tomography scan)
-
Anthropometric measures (weight, waist circumference, body composition using Dual Energy X-ray Absorptiometry (DEXA))
-
Lipid, lipoprotein profile
-
Glycemia, insulinemia and HbA1c
-
Adipokines, inflammatory and hemostatic markers
-
To evaluate the percentage of patients with metabolic syndrome at 12 months
-
To evaluate the safety and tolerability of rimonabant in these patients
In four selected US sites the effect of rimonabant at 12 months will be also assessed on:
-
Basal lipolysis and insulin suppressed lipolysis (euglycemic hyperinsulinemic clamp).
-
Resting metabolic rate and substrate oxidation at rest using indirect calorimetry.
-
Adipose tissue histology and expression of genes involved in glucose and lipid metabolism (superficial adipose tissue biopsy).
