Major Depressive Disorder Clinical Trial
Official title:
Placebo-Controlled, Double-Blind, Parallel Group-Comparison Study of Aripiprazole as an Adjunctive Therapy in Patients With Major Depressive Disorder
To examine the efficacy and safety of aripiprazole versus placebo as an adjunctive therapy co-administered with either an selective serotonin reuptake inhibitor (SSRI) or a serotonin-norepinephrine reuptake inhibitor (SNRI) in patients with major depressive disorder.

Patients who have previously received electro-convulsive therapy 5. Patients who have participated in clinical studies on medical devices or other drugs within the past month 6. Patients at risk of having serious adverse events or developing symptoms that could interfere with safety and efficacy evaluations (such as symptoms of fibromyalgia syndrome overlapping with symptoms of depression), based on previous medical history 7. Patients with a history or a complication of diabetes 8. Patients with thyroid disease (excluding patients who are stabilized on drug therapy for at least 3 months) 9.

---|---|---|---|---|
Primary | Mean Change in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score | The change in MADRS total score from the end of the SSRI/SNRI treatment period to Week 6 of the placebo-controlled, double-blind treatment period by covariance analysis, and compared the aripiprazole variable dose group with the placebo group as well as the aripiprazole fixed dose group with the placebo group. Higher MADRS score indicates more severe depression, and each item yields a score of 0 to 6. The overall score ranges from 0 to 60. The questionnaire includes questions on the following symptoms 1. Apparent sadness 2. Reported sadness 3. Inner tension 4. Reduced sleep 5. Reduced appetite 6. Concentration difficulties 7. Lassitude 8. Inability to feel 9. Pessimistic thoughts 10. Suicidal thoughts |
Baseline (the end of the SSRI/SNRI treatment period), at completion of administration | No |
Secondary | MADRS Response Rate | The percentage of subjects with a decrease in MADRS total score of 50% or more, from the end of the SSRI/SNRI treatment period to the end of the placebo-controlled, double-blind treatment period (or withdrawal). | Baseline (the end of the SSRI/SNRI treatment period), at completion of administration | No |
Secondary | Mean Change in Sheehan Disability Scale (SDISS) | The endpoint evaluated the change in SDISS from the end of the SSRI/SNRI treatment period to Week 6 of the placebo-controlled, double-blind treatment period. The patient rates the extent to which his or her 1) work, 2) social life or leisure activities, and 3) home life or family responsibilities are impaired by his or her symptoms on a 10-point visual analog scale. The three items may be summed into a single dimensional measure of global functional impairment that ranges from 0 (unimpaired) to 30 (highly impaired). |
Baseline (the end of the SSRI/SNRI treatment period), at completion of administration | No |
