Trial Outcomes & Findings for This is a Study to Determine the Antidepressant Effects of AZD6765 (NCT NCT00986479)

NCT ID: NCT00986479

Last Updated: 2014-10-21

Results Overview

Montgomery-Asberg Depression Rating Scale (MADRS) is a 10-item instrument used for the evaluation of depressive symptoms. Each item is rated on a scale of 0 to 6 (with higher scores indicating more severe depression). The individual item scores are added together to form a total score, ranging between 0 and 60. 0 is considered the best score, 60 the worst.

Participant Flow

A total of 27 patients were enrolled. Of these, 22 patients were randomized to either: (1) AZD6765 (150 mg) followed by placebo or (2) placebo followed by AZD6765 (150 mg) in a crossover study design. A total of 20 patients completed both treatment periods of the study.

Scale for Suicide Ideation (SSI) is a 19-item scale designed to quantify the intensity of current conscious suicide ideation. Each item is rated on a scale of 0 to 2 (with higher scores indicating greater suicidal ideation). The individual item scores are added together to form a total score, ranging between 0 and 38. 0 is considered the best outcome, 38 the worst.

Hamilton Depression Rating Scale-17 item (HDRS) is a scale that assesses depressive symptoms. HDRS consists of 17 symptoms, each of which is rated from 0 to 2 or 0 to 4, where 0 is none/absent. The total score is calculated as the sum of the 17 individual symptom scores; the total score can range from 0 to 52. Higher scores indicate more severe depression.

Clinician- Administered Dissociative States Scale (CADSS) is a clinician-administered measure of perceptual, behavioral, and attentional alterations occurring during dissociative experiences. This scale involves a 23 questions and each is rated from 0 (not at all) to 4 (extremely). The total score is sum of the 23 items and range from 0 to 92 - best is 0 and worst is 92.

The Brief Psychiatric Rating Scale (BPRS) is a 18-item scale which measures symptoms and behaviors that are characteristic of schizophrenia. Each item is rated from 1 to 7 with higher score indicating greater severity. The total score is the sum of the 18 items, resulting in a range of scores from 18-126. 18 is considered to be the best outcome, 126 the worst.

Beck Depression Inventory (BDI) is a 21-question instrument for measuring the severity of depression. Each question has a set of at least four possible answer choices, ranging in intensity. A value of 0 to 3 is assigned for each answer and the total score is computed. Higher total scores indicate more severe depressive symptoms.
