Name Time Method Main Objective: To assess the efficacy of agomelatine (25 mg/50 mg), in the prevention of depressive relapse, in ambulatory patients suffering from Major Depressive Disorder, during 24 weeks of treatment after an initial response to agomelatine 25 mg or 50 mg.;Secondary Objective: To provide additional safety data on long term use of agomelatine.;Primary end point(s): Primary efficacy criterion = relapse defined as:<br>- HAM-D 17-item total score = 16 <br>- or any withdrawal for lack of efficacy during the double-blind period according to the clinical opinion of the investigators. It should be based on the evolution of both Hamilton and Clinical Global Impression scores and reviewed at the end of the study by the Coordinator's Committee.<br>- or suicide/attempt according to the opinion of the Coordinators Committee at the end of the study.<br><br>Main expression of the primary efficacy criterion : time to relapse (days)<br><br><br>
