Study type | Interventional |
This is a 6-week comparison of asenapine versus placebo as an add-on to ongoing
antidepressant treatment in patients with major depression who have not had a complete
therapeutic response to treatment with the antidepressant alone.
The investigators hypothesize that added asenapine will produce greater reductions in
depression than will added placebo.

Primary | Change in MADRS Total Score | The Montgomery Asberg Depression Rating Scale (MADRS) is used by clinicians to assess the severity of depression among patients with a diagnosis of depression. It is designed to be sensitive to change resulting from antidepressant therapy. MADRS is a 10-item scale. Each MADRS item is rated on a 0 to 6 scale. The MADRS Total score ranges from 0 (min) to 60 (max). Higher MADRS scores indicate higher levels of depressive symptoms. |
Baseline, 6 weeks | No |
Secondary | Study Completion Rate | The percentage of patients completing the study in their assigned treatment arm (asenapine or placebo) at the end of 6 weeks | 6 weeks | No |
Secondary | Clinical Response Rate | Clinical Response rate will be defined as the number of participants with a > 50% reduction from baseline in MADRS total score. MADRS is a 10-item scale. Each MADRS item is rated on a 0 to 6 scale. The MADRS Total score ranges from 0 (min) to 60 (max). Higher MADRS scores indicate higher levels of depressive symptoms. |
Baseline, 6 weeks | No |
Secondary | Clinical Remission Rate | Clinical Remission will be defined as the number of participants with a MADRS total score < 7. MADRS is a 10-item scale. Each MADRS item is rated on a 0 to 6 scale. The MADRS Total score ranges from 0 (min) to 60 (max). Higher MADRS scores indicate higher levels of depressive symptoms. |
6 weeks | No |
Secondary | Rates of Sustained Remission | Sustained remission will be defined as at least two consecutive post-randomization assessments (weeks 2, 4, and 6) during which minimal depressive psychopathology (MADRS < 7) is present. MADRS is a 10-item scale. Each MADRS item is rated on a 0 to 6 scale. The MADRS Total score ranges from 0 (min) to 60 (max). Higher MADRS scores indicate higher levels of depressive symptoms. |
