Efficacy and Safety of SR58611A in Patients With Major Depressive Disorder
An Eight-Week, Double-Blind, Placebo Controlled, Multicenter Study With Escitalopram (10 mg qd) as Positive Control, Evaluating the Efficacy, Safety, Tolerability of a Fixed Dose of SR58611A (350 mg q12) in Outpatients With MDD

To evaluate the efficacy of a fixed dose of SR58611A(350 mg q12) compared to placebo in patients with MajorDepressive Disorder (MDD) using escitalopram (10 mgqd) as positive control. The study is a multicenter, US and Canadian, randomized, double-blind, 3-parallel-group, placebo- and escitalopram-controlled, Phase III study consisting of four segments (A, B, C and D). Segment A is a 1-week, placebo, single-blind period. Segment B is an 8-week, double-blind period. Segment C is an optional 18-week double-blind extension period. Segment D is a 1-week safety follow-up period after study drug discontinuation or early termination (during Segment B or C).

To evaluate the efficacy of a fixed dose of SR58611A(350 mg q12) compared to placebo in patients with MajorDepressive Disorder (MDD) using escitalopram (10 mgqd) as positive control. The present study is an 8-week, double-blind, placebo- and escitalopram-controlled, randomized, parallel-group study. A 1-week, placebo, single-blind period precedes the 8-week randomized treatment period and an optional 18-week, double-blind extension period follows the randomized treatment period. A Safety Follow up Visit is scheduled 1 week after the acute and extension period, or early termination. Escitalopram, a selective serotonin reuptake inhibitor (SSRI), an approved treatment for MDD, is chosen as a positive control agent in this study. The dose of 10 mg is within the approved dose range with no need for dose adjustment in elderly patients. This trial is designed to formally compare the efficacy, safety, and tolerability of SR58611A to placebo. Escitalopram is used as a positive control.
