What is being measured
The primary outcome is the main question the study is designed to answer.
Montgomery-Asberg Depression Rating Scale (MADRS) Total Score.
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.
Measured: 60 minutes (min) prior to dosing (baseline); and 60 min, 80 min, 110 min, 230 min, 1 day, 2 days, 3 days and 7 days following dosing.
Secondary outcomes (12)
The Number of Participants With Montgomery-Asberg Depression Rating Scale (MADRS) Total Score Less Than 10 (MADRS Remission).
Remission defined as a Montgomery-Asberg Depression Rating Scale (MADRS) total score <10. 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.
Measured: 60 minutes (min) prior to dosing (baseline); and 60 min, 80 min, 110 min, 230 min, 1 day, 2 days, 3 days and 7 days following dosing.
The Number of Participants With at Least 50% Reduction in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score (MADRS Response).
Response defined as a >= 50% reduction from baseline in MADRS total score. 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.
Measured: 60 minutes (min) prior to dosing (baseline); and 60 min, 80 min, 110 min, 230 min, 1 day, 2 days, 3 days and 7 days following dosing.
Scale for Suicide Ideation (SSI) Total Score.
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.
Measured: 60 minutes (min) prior to dosing (baseline); and 60 min, 80 min, 110 min, 230 min, 1 day, 2 days, 3 days and 7 days following dosing.
Hamilton Anxiety Rating Scale (HAM-A) Total Score.
Hamilton Anxiety Rating Scale (HAM-A) is used as a rating measure of anxiety severity. The scale consists of 14 items. Each item is rated on a scale of 0 to 4. The HAM-A total score is the sum of the 14 items and the score ranges from 0 to 56. 0 is considered the best outcome, 56 the worst.
Measured: 60 minutes (min) prior to dosing (baseline); and 230 min, 1 day, 2 days, 3 days and 7 days following dosing.
Hamilton Depression Rating Scale-17 Item (HDRS) Total Score
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.
Measured: 60 minutes (min) prior to dosing (baseline); and 60 min, 80 min, 110 min, 230 min, 1 day, 2 days, 3 days and 7 days following dosing
Visual Analogue Scale (VAS) Depressed Score
The Visual Analog Scale (VAS) Depressed is a 0 to 100-mm self-administered scale where patients rate their mood between "extreme sad" (0-mm) and "extreme happy" (100-mm), with a median "normal" point.
Measured: 60 minutes (min) prior to dosing (baseline); and 60 min, 80 min, 110 min, 230 min, 1 day, 2 days, 3 days and 7 days following dosing
Clinician-Administered Dissociative States Scale (CADSS) Score.
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.
Measured: 60 minutes (min) prior to dosing (baseline); and 60 min, 80 min, 110 min, 230 min, 1 day, 2 days, 3 days and 7 days following dosing
Brief Psychiatric Rating Scale (BPRS) Score.
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.
Measured: 60 minutes (min) prior to dosing (baseline); and 60 min, 80 min, 110 min, 230 min, 1 day, 2 days, 3 days and 7 days following dosing.
Beck Depression Inventory (BDI) Score.
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.
Measured: 60 minutes (min) prior to dosing (baseline); and 60 min, 80 min, 110 min, 230 min, 1 day, 2 days, 3 days and 7 days following dosing.
Young Mania Rating Scale (YMRS) Score.
Young Mania Rating Scale (YMRS) consists of 11 items, rated on a scale from 0 (symptom not present) to 8 (symptom extremely severe) or from 0 (symptom not present) to 4 (symptom extremely severe). The YMRS total score ranges from 0 to 60. 0 is considered to be the best outcome, 60 the worst.
Measured: 60 minutes (min) prior to dosing (baseline); and 60 min, 80 min, 110 min, 230 min, 1 day, 2 days, 3 days and 7 days following dosing.
Visual Analogue Scale (VAS) Anxious Score.
The Visual Analog Scale (VAS) Anxious is a 0 to 100-mm self-administered scale where patients rate their mood between "extreme sad" (0-mm) and "extreme happy" (100-mm), with a median "normal" point.
Measured: 60 minutes (min) prior to dosing (baseline); and 60 min, 80 min, 110 min, 230 min, 1 day, 2 days, 3 days and 7 days following dosing.
Brief Psychiatric Rating Scale (BPRS) Positive Score.
Brief Psychiatric Rating Scale (BPRS) Positive is a 4-item scale which measures positive symptoms of schizophrenia (conceptual disorganization, hallucinatory behavior, suspiciousness, and unusual thought content). Each item is rated from 1 to 7 with higher score indicating greater severity. The total score is the sum of the 4 items, resulting in a range of scores from 4-28.
Measured: 60 minutes (min) prior to dosing (baseline); and 60 min, 80 min, 110 min, 230 min, 1 day, 2 days, 3 days and 7 days following dosing.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing AZD6765 in people with Treatment Resistant Major Depressive Disorder, run by AstraZeneca at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 21 Oct 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 21 Oct 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Montgomery-Asberg Depression Rating Scale (MADRS) Total Score. (time frame: 60 minutes (min) prior to dosing (baseline); and 60 min, 80 min, 110 min, 230 min, 1 day, 2 days, 3 days and 7 days following dosing.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00986479, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
