Clinical Trial Summary

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.


Description:

The investigators will undertake a 6-week, double-blind, randomized, parallel-group, placebo-controlled trial of adjunctive asenapine in 130 patients with MDD without psychosis who have had an incomplete therapeutic response to treatment with an antidepressant medication alone.

Outcome

Type Measure Description Time frame Safety issue
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.
2, 4, 6 weeks No
