Primary Outcome Measures:
  • 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 ]

Secondary Outcome Measures:
  • To determine whether AZD6765 will demonstrate a superior antidepressant efficacy compared to placebo, as assessed by the proportion of subjects in remission (defined as MADRS total score ≤10). [ Time Frame: MADRS will be assessed every day from Day 1 through Day 10 and on Day 14 ] [ Designated as safety issue: No ]
  • To determine whether AZD6765 will demonstrate a superior response compared to placebo, as assessed by the proportion of subjects with response (defined as a ≥50% reduction from baseline in the MADRS total score). [ Time Frame: Blood samples will be obtained on Days 1-4 and 7-11. ] [ Designated as safety issue: No ]
  • To evaluate the efficacy of AZD6765 in reducing suicidal ideation, as assessed by a change from baseline in the Scale for Suicide Ideation (SSI) total score. [ Time Frame: SSI will be assessed every day from Day 1 through Day 10 and on Day 14 ] [ Designated as safety issue: No ]
