Primary Outcome Measures:
  • Change From Baseline in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score to Week 9. [ Time Frame: Baseline to Week 9 ] [ Designated as safety issue: No ]
    MADRS total score (0-60 units), where lower scores indicate less depressive symptoms, calculated as Week 9 value - baseline value.

Secondary Outcome Measures:
  • Change From Baseline in Health-related Quality of Life, Enjoyment and Satisfaction (Q-LES-Q) [ Time Frame: Baseline to Week 9 ] [ Designated as safety issue: No ]
    Q-LES-Q as percent of maximum (0 to 100%) calculated as Week 9 - baseline, where higher values indicate better quality of life.

  • Change From Baseline for Satisfaction With Medication From Quality of Life, Enjoyment, Satisfaction Questionaire (Q-LES-Q) [ Time Frame: Baseline to Week 9 ] [ Designated as safety issue: No ]
    Item 15 the Quality of Life, Enjoyment Satisfaction Questionnaire (score 1 least -5 best) on Q-LES-Q, calculated as Week 9 value - baseline value

  • Change From Baseline in Anxiety Symptoms Measured by Hamilton Anxiety 14 Item Scale (HAM-A) [ Time Frame: Baseline to Week 9 ] [ Designated as safety issue: No ]
    Change in HAM-A total score (total score 0-56), calculated as Week 9 value - baseline value, where lower scores indicate less anxiety.

  • Change From Baseline in Sleep Quality as Measured by the Pittsburgh Sleep Quality Index [ Time Frame: Baseline to Week 9 ] [ Designated as safety issue: No ]
    The Pittsburgh Sleep Quality Index is an eighteen questionnaire scored with 7 sleep component scores each on a 0 to 3 scale, total score range from 0 to 21, worst value 21, best value 0

  • Change From Baseline in Suicidal Thoughts as Measured by Montgomery-Asberg Depression Rating Scale (MADRS) Item 10 [ Time Frame: Baseline to Week 9 ] [ Designated as safety issue: Yes ]
    The suicide item is a single item of the Montgomery-Asberg Depression Rating Scale with a range of values from 0 to 6, worst value 6, best value 0

  • Change From Baseline in Somatic Symptoms Cluster From the Hamilton Anxiety Scale (HAM-A) [ Time Frame: Baseline to Week 9 ] [ Designated as safety issue: No ]
    The Somatic symptom Cluster of the Hamilton Anxiety Scale is a 7 item cluster associated with somatic symptoms *somatic muscular, somatic sensory, cardiovascular system, respiratory system, gastrointestinal system, genitourinary system, autonomic system) with a range of values from 0 to 28, worst value 28, best value 0

  • Tolerability as Measured by Adverse Event Withdrawals During Treatment [ Time Frame: Baseline to Week 9 ] [ Designated as safety issue: Yes ]
