The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
The purpose of the study is to evaluate the long-term safety of saredutant (or SR48968C) in adult and elderly patients with depression.The primary objective is to evaluate the long-term safety and tolerability of a 100 mg dose of saredutant in adult and elderly patients with depression. The secondary objective is to evaluate blood levels of saredutant.
Condition or disease
Drug: Saredutant succinate (SR48968C)
The study is a multicenter, US, open-label study consisting of two segments (A and B). Segment A is a minimum 1-week (maximum 4-week) screening period and Segment B is a 52-week, open-label period. All treated 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.
The primary outcome is the proportion of patients experiencing at least one treatment-emergent adverse event.
Secondary Outcome Measures :
The main secondary outcomes are incidences of potentially clinically significant abnormalities and the changes from baseline in the values for clinical laboratories, vital signs, and electrocardiogram parameters.
