Primary Outcome Measures:
  • Change in Positive and Negative Syndrome Scale (PANSS) Total Score [ Time Frame: From Day 1 (baseline) to Day 42 ] [ Designated as safety issue: Yes ]

    Change in Positive and Negative Syndrome Scale Total Score from Day 1 (baseline) to Day 42 (final visit) or withdrawal. Minimum value of total PANSS is 30 , Maximum is 210.

    Minimum value considered better is score decreased from baseline at least 30%.



Secondary Outcome Measures:
  • Change in Clinical Global Impression - Severity of Illness (CGI-S) Score [ Time Frame: From Day 1 (Baseline) to Day 42 ] [ Designated as safety issue: Yes ]
    Clinical Global Impression - Severity of Illness. Maximum possible value is 7 (worst outcome), the minimum is 1 (best outcome). Values are considered better outcome: decrease from baseline > 1 score.

  • Clinical Global Impression - Severity of Illness (CGI-S) Score [ Time Frame: Day 14 ] [ Designated as safety issue: Yes ]
    Clinical Global Impression - Severity of Illness. Maximum possible value is 7 (worst outcome), the minimum is 1 (best outcome). Values are considered better outcome: decrease from baseline > 1 score.
