The purpose of this study is to evaluate the efficacy of GFT505 80mg in reducing serum Triglycerides (TG) and increasing High Density Lipoprotein Cholesterol (HDL-C) levels compared with placebo in atherogenic dyslipidaemic patients with abdominal obesity, and to assess the tolerability and safety of once-a-day administrations of oral doses of GFT505 during 28 days.

The study period per patient is 7 to 14 weeks: a screening period (1 to 8 weeks) will precede a 4-week double-blind treatment period and a 2-week follow-up period.

During the screening period, patients will be asked to start or continue adequate diet and exercise and to stop their lipid-lowering medication (for not treatment-naïve patients). For patient taking any lipid-regulating medication, a minimum of 8-week wash-out from lipid-regulating therapies (fibrates, statins, …) is required.

Inclusion Criteria:

• Male or post-menopausal female.
• Waist circumference ≥102cm for male, ≥ 88cm for female.
• Atherogenic dislipidaemia inadequately controlled despite Therapeutic Lifestyle Change (TLC) recommendations (diet and exercise).
• 150≤ fasting TG ≤ 600 mg/dL (1.69 ≤ fasting TG ≤ 6.78 mmol/L) at V2.
• Fasting HDL-C ≤ 40 mg/dL (≤ 1.03 mmol/L) for male, HDL-C ≤ 45 mg/dL (≤ 1.16 mmol/L) for female at V2.

Exclusion Criteria:

• Body Mass Index (BMI) ≥ 40 kg/m².
• Blood Pressure > 160 / 95 mmHg.
• Type I or type II Diabetes Mellitus.
