Phase 2
Completed
Conditions
Major Depressive Disorder
Interventions
Drug: Placebo (for SSR411298)
Registration Number
NCT00822744
Lead Sponsor
Sanofi
Brief Summary

The primary objective of this study is to evaluate the efficacy of 3 fixed doses of SSR411298 (10, 50 or 200 mg daily) compared to placebo, in elderly patients with Major Depressive Disorder (MDD), based on the 17-item Hamilton Depression Rating Scale.

Secondary objectives are:

* To evaluate the effect of SSR411298 on disability, anxiety, cognitive function, sleep, pain and somatic symptoms related to depression, and bone markers.

* To assess SSR411298 plasma concentrations.

* To assess plasma endocannabinoid concentrations.

Detailed Description

The study period for a participants is approximately 10 weeks including a screening up to 1 week, 8-week treatment and 1-week follow-up.

Primary Outcome Measures
NameTimeMethod
17-item Hamilton Depression Rating Scale (HAM-D) total score8 weeks (from D-1 (before randomization) up to D56)

The HAM-D consists of 17 items assessing signs and symptoms of depression. All items are scored with a severity rating from 0 (not present) to 2 or 4 (very severe), depending on the item. The minimum and maximum possible scores are 0 and 52, respectively.

Secondary Outcome Measures
NameTimeMethod
Geriatric Depression Scale (GDS) total scoreD-1 (before randomization) and D56

The GDS is a 15-item self report scale used to assess the more specific aspects of depression in elderly depressed patients.

Montgomery-Asberg Depression Rating Scale (MADRS) total score8 weeks (from D-1 (before randomization) up to D56)

The MADRS consists of 10 items assessing signs and symptoms of depression. All items are scored with a severity rating from 0 (not present) to 6 (most severe). The minimum and maximum possible scores are 0 and 60, respectively.

Clinical Global Impression (CGI) scoresD-1 (before randomization) and D56

The CGI-1 Severity of Illness score is rated on a 1 to 7 point scale.

The CGI-2 Improvement score is a component of the CGI; the Improvement score captures the investigator's clinical impression regarding global improvement (or worsening) on a 7-point scale.

HAM-D depressed mood item score, factor scores and core item score8 weeks (from D-1 (before randomization) up to D56)
Sheehan Disability Scale (SDS) total scoreD-1 (before randomization) and D56

The SDS contains 3 questions, which assesses interference in three domains, work and school, family life and home responsibilities, and social life. Each question is answered on a 10-point Likert Scale.

Hamilton Anxiety Rating scale (HAM-A) total scoreD-1 (before randomization) and D56

The HAM-A consists of 14 items assessing signs and symptoms of anxiety. All items are scored with a severity rating from 0 (not present) to 2 or 4 (very severe), depending on the item. The minimum and maximum possible scores are 0 and 56 respectively.

Overview of Adverse Events (AE)up to 9 weeks (from first study drug intake up to 7 days after last study drug intake)
SSR411298 plasma concentrationpredose and 3-5 hours after study drug intake on Day 21 and Day 56

Plasma concentrations of SSR411298 are determined by a validated liquid chromatography tandem mass spectrometry method with a lower limit of quantification of 10 ng/mL.
