Brief Summary

The purpose of the study is to evaluate the efficacy and safety of saredutant (or SR48968C) in patients with depression.

The primary objective is to evaluate the efficacy of a 100 mg dose of saredutant compared to placebo in patients with depression.

The secondary objectives are to evaluate the safety of saredutant, to evaluate the efficacy of saredutant on disability and quality of life in patients with depression, and to evaluate blood levels of saredutant.

Detailed Description

The study is a multicenter, US, randomized, parallel-group, double blind, placebo and paroxetine-controlled study consisting of three segments (A, B, and C). Segment A is a 1-week, placebo, single-blind period and Segment B is an 8-week, double blind period. Patients completing Segment B may be eligible for enrollment into Segment C, a 44-week, double blind extension. All randomized patients must complete a post-study telephone visit and a post-study office visit 3 days and 1 week, respectively, after intake of the last dose of study medication.
