  Purpose

The purpose of this research study is to determine whether AZD6765 has an effect on the patient's depression when taken together with current depression medication. In addition, information will be gathered on how well AZD6765 is tolerated, investigate the levels of AZD6765 and the levels of the current depression medication in the blood. In addition, the research staff will determine if AZD6765 has any mood or calming effects (how you feel).

Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • To give evidence of an antidepressant effect versus placebo, given together with another antidepressant confirmed by change in the MADRS total score [ Time Frame: Baseline to week 3 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To determine if the antidepressant effect can be achieved at week 3 with AZD6765 (100 or 150 mg/infusion) versus placebo by assessing a change from baseline to week 3 in the MADRS total score. [ Time Frame: 3 weeks ] [ Designated as safety issue: No ]
  • To evaluate the rapid antidepressant efficacy of AZD6765 at 1 day after a first infusion, as assessed by a change in the Quick Inventory of Depressive Symptomology Self-Report 16-item scale (QIDS-SR-16) total score. [ Time Frame: baseline to Day 1 ] [ Designated as safety issue: No ]
  • • To assess the safety and tolerability of multiple infusions when administered concomitantly with other anti-depressants by incidence of AEs. [ Time Frame: 8 weeks ] [ Designated as safety issue: Yes ]
