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. ] [ Designated as safety issue: No ]
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.
The primary objective of the study is to assess the efficacy of a single-intravenous infusion of AZD6765 compared to placebo. [ Time Frame: Montgomery-Asberg Depression Rating Scale (MADRS) change from baseline will be measured at pre-dose, 60, 80, 110 and 230 minutes and 24, 48 and 72 hours post-dose. ] [ Designated as safety issue: No ]

    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.
  • The Number of Participants With at Least 50% Reduction in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score (MADRS Response).

    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.

    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.
  • Clinician-Administered Dissociative States Scale (CADSS) 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 ] [ Designated as safety issue: No ]
    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.
  • Brief Psychiatric Rating Scale (BPRS) 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. ] [ Designated as safety issue: No ]

    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) 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. ] [ Designated as safety issue: No ]
    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.
