Primary Objective: To assess in overweight to obese subjects the change in sleep energy expenditure after repeated subcutaneous (SC) doses of SAR425899. Secondary Objectives: * To assess the change in resting, basal and total daily energy expenditure. * To assess the change in respiratory quotient, fat, protein and carbohydrate oxidation. * To assess the change in body composition and core temperature. * To assess the pharmacodynamic effects on fasting plasma glucose, biomarkers of lipid metabolism and glycated hemoglobin (HbA1c). * To assess the pharmacokinetic parameters for SAR425899 after repeated SC doses. * To assess the safety and tolerability.
Study duration is approximately 7-8 weeks including a screening period, a 19-day treatment period and an end-of-study visit 7 days after last dosing.
