To assess the effect of rimonabant, micronised fenofibrate and their combination on anthropometric and metabolic parameters in overweight/obese patients with dyslipidaemia. All patients (n = 30) received a hypocaloric diet ( approximately 600 kcal/day deficit) and were randomly allocated to receive open-label rimonabant (R) 20 mg/day (n = 10), micronised fenofibrate (F) 200 mg/day (n = 10) or rimonabant 20 mg/day plus fenofibrate 200 mg/day (RF) (n = 10). Anthropometric and metabolic parameters were assessed at baseline and 3 months after treatment initiation. Compared with baseline similar significant reductions in body weight, body mass index and waist circumference were observed in the R (-6, -5 and -5%, respectively; p < 0.01) and RF group (-5% for all, p < 0.05), while improvements in these parameters were smaller in the F group (-2, -2.5 and -2%, respectively; p < 0.05). Triglycerides were reduced by 18% in the R group (p = NS), by 39% in the F group (p < 0.001) and by 46% in the RF group (p < 0.05). Importantly, combination treatment resulted in a 42% increase in high-density lipoprotein cholesterol (HDL-C) levels (p < 0.05), while HDL-C was not significantly altered in the two monotherapy groups. Subsequently, a more pronounced increase in apolipoprotein A-I (ApoA-I) levels (+25%) was observed in the RF group compared with changes in both monotherapy groups (p < 0.0001 vs R and p < 0.005 vs F group). Low-density lipoprotein cholesterol (LDL-C) levels were not significantly altered in any group. Apolipoprotein B (apoB) levels were reduced in all groups and this reduction was significantly more pronounced in the RF group (p < 0.05 vs baseline as well as p < 0.005 and p < 0.01 for RF vs R and F groups, respectively). ApoB/apoA-I ratio decreased by 3% with R (p = NS), by 18% with F (p < 0.05) and by 40% with RF treatment (p < 0.01). Total cholesterol to HDL-C ratio decreased by 20% with F (p < 0.0001) and by 33% with RF therapy (p < 0.005), while it was not significantly altered in R group. The combination of rimonabant and fenofibrate may further improve metabolic parameters in overweight/obese patients with dyslipidaemia compared with each monotherapy. This improvement is particularly pronounced for HDL-C levels.
