Brief Summary:
The purpose of this study is to assess the effect and safety of AZD6765 in patients with major depressive disorder who exhibit inadequate response to antidepressants. AZD6765 is a channel blocker of the N-methyl-D-aspartate (NMDA) class of glutamate receptors.

Primary Outcome Measures :
  1. Change From Baseline to Week 6 in the Montgomery-Asberg Depression Rating Scale (MADRS) Total Score [ Time Frame: Baseline to Week 6 ]
    A 10-item scale for the evaluation of depressive symptoms. Each MADRS item is rated on a 0 to 6 scale. The MADRS total score is calculated as the sum of the 10 individual item scores; the total score can range from 0 to 60. Higher MADRS scores indicate higher levels of depressive symptoms.


Secondary Outcome Measures :
  1. Change From Baseline to Week 12 in the Montgomery-Asberg Depression Rating Scale (MADRS) Total Score [ Time Frame: Baseline to Week 12 ]
    A 10-item scale for the evaluation of depressive symptoms. Each MADRS item is rated on a 0 to 6 scale. The MADRS total score is calculated as the sum of the 10 individual item scores; the total score can range from 0 to 60. Higher MADRS scores indicate higher levels of depressive symptoms.

  2. Percentage of Patients With Sustained Response From Week 6 to Week 12 (Defined as ≥50% Reduction From Baseline in the MADRS Total Score at Week 6 and Which is Maintained Through Week 12) [ Time Frame: Week 6 to Week 12 ]
    The percentage of patients with with Sustained Response (defined as ≥50% reduction from baseline in the MADRS total score at Week 6 and which is maintained through Week 12) was calculated.

  3. Percentage of Patients Who Were Responders (Defined as a ≥50% Reduction From Baseline in MADRS Total Score) at Week 6 [ Time Frame: Baseline to Week 6 ]
    The percentage of patients who were Responders (defined as ≥50% reduction from baseline in MADRS total score) was calculated.

  4. Percentage of Patients Who Were Responders (Defined as a ≥50% Reduction From Baseline in MADRS Total Score) at Week 12 [ Time Frame: Baseline to Week 12 ]
    The percentage of patients who were Responders (defined as ≥50% reduction from baseline in MADRS total score) was calculated.

  5. Percentage of Patients Who Were Remitted (Defined as MADRS Total Score ≤10) at Week 6 [ Time Frame: Baseline to Week 6 ]
    The percentage of patients who were Remitted (defined as MADRS total score ≤10) was calculated.

  6. Percentage of Patients Who Were Remitted (Defined as MADRS Total Score ≤10) at Week 12 [ Time Frame: Baseline to Week 12 ]
    The percentage of patients who were Remitted (defined as MADRS total score ≤10) was calculated.

  7. Change From Baseline in Functional Impairment as Measured by the Change From Baseline in the Sheehan Disability Scale (SDS) Total Score [ Time Frame: Baseline to Week 12 ]
    A 3-item, self-administered scale that measures the extent a patient is impaired by their disease. Higher scores indicate more severe impairment. The SDS total score is calculated as the sum of the score for the 3 intercorrelated domains (school/work, social life, and family life/home responsibilities), ranges from 0 (no impairment) to 30 (most severe impairment).

  8. Change in Severity of Depressive Symptoms as Measured by Change From Baseline in the Clinical Global Impression-Severity (CGI-S) Score [ Time Frame: Baseline to Week 12 ]
    Clinical Global Impression - Severity (CGI-S) scale rates the severity of the patient's illness at the time of assessment, range from 1 (normal, not ill) to 7 (very severely ill).

  9. Change in Severity of Depressive Symptoms as Measured by the CGI-I Response (Defined as CGI-I Rating of "Very Much Improved" or "Much Improved") at Week 6 [ Time Frame: Baseline to Week 6 ]
    A 3-part, clinician-administered scale that rates the improvement or worsening of the patient's illness from randomization (baseline). Each item is scored on a 1 to 7 scale. CGI-I scores >4 indicate worsening, while scores <4 indicate improvement.

  10. Change in Severity of Depressive Symptoms as Measured by the CGI-I Response (Defined as CGI-I Rating of "Very Much Improved" or "Much Improved") at Week 12 [ Time Frame: Baseline to Week 12 ]
    A 3-part, clinician-administered scale that rates the improvement or worsening of the patient's illness from randomization (baseline). Each item is scored on a 1 to 7 scale. CGI-I scores >4 indicate worsening, while scores <4 indicate improvement.

  11. Change From Baseline in Self-rated Severity of Depressive Symptoms as Measured by Quick Inventory of Depressive Symptomatology Self-Rated 16-item Scale (QIDS-SR-16) Total Score [ Time Frame: Baseline to Week 12 ]
    A 16-question self-report inventory that includes the 9 Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM-IV-TR) criteria symptom domains: sad mood, concentration, self-outlook, suicidal ideation, involvement, energy/fatigability, sleep disturbance (4 items: initial, middle, late insomnia, and hypersomnia), appetite/weight increased or decrease (4 items), and psychomotor agitation/retardation (2 items). The QIDS-SR-16 total scores range from 0 (least severe) to 27 (most severe).
