Primary Outcome Measures:
  • Change From Baseline in MADRS Total Score After 6 Weeks of Treatment [ Time Frame: Baseline and Week 6 ]
    The Montgomery Åsberg Depression Rating Scale (MADRS) is a depression rating scale consisting of 10 items, each rated 0 (no symptom) to 6 (severe symptom). The 10 items represent the core symptoms of depressive illness. The rating should be based on a clinical interview with the patient, moving from broadly phrased questions about symptoms to more detailed ones, which allow a precise rating of severity, covering the last 7 days. Total score from 0 to 60. The higher the score, the more severe.

Secondary Outcome Measures:
  • Change From Baseline in MADRS Total Score After 1 Week of Treatment [ Time Frame: Baseline and Week 1 ]
  • Change From Baseline in HAM-D 24 Total Score After 6 Weeks of Treatment [ Time Frame: Baseline and Week 6 ]
    The 24-item Hamilton Depression Rating Scale (HAM-D) is based on the 21-item HAM-D plus an additional 3 items (helplessness, hopelessness, and worthlessness). The observer makes his/her assessment on the basis of a specific statement, content, tone, facial expression, and gestures of the patient during the interview, and scores each item from 0 to 2 or 0 to 4. Total score from 0 to 76. The higher the score, the more severe.

  • Change From Baseline in HAM-A Total Score After 6 Weeks of Treatment [ Time Frame: Baseline and Week 6 ]
    The Hamilton Anxiety Rating Scale (HAM-A) consists of 14 items that assess anxious mood, tension, fear, insomnia, intellectual (cognitive) symptoms, depressed mood, behaviour at interview, somatic (sensory), cardiovascular, respiratory, gastrointestinal, genitourinary, autonomic, and somatic (muscular) symptoms. Each symptom is rated from 0 (absent) to 4 (maximum severity). Total score from 0 to 56. The higher the score, the more severe.

  • Change From Baseline in CGI-S Score After 6 Weeks of Treatment [ Time Frame: Baseline and Week 6 ]
    The Clinical Global Impression - Severity of Illness (CGI-S) is a 7-point scale rated from 1 (normal, not at all ill) to 7 (among the most extremely ill patients). The investigator should use his/her total clinical experience with this patient population to judge how mentally ill the patient is at the time of rating.

  • Change in Clinical Status Using CGI-I Score at Week 6 [ Time Frame: Week 6 ]
    The Clinical Global Impression - Global Improvement (CGI-I) is a 7-point scale rated from 1 (very much improved) to 7 (very much worse). The investigator rated the patient's overall improvement relative to baseline, whether or not, in the opinion of the investigator, this was entirely due to the drug treatment.

  • Proportion of Responders at Week 6 (Response Defined as a >=50% Decrease in the MADRS Total Score From Baseline) [ Time Frame: Week 6 ]
  • Proportion of Remitters at Week 6 (Remission is Defined as a MADRS Total Score <=10) [ Time Frame: Week 6 ]
