    Outcome Measures

    Primary Outcome Measures

    1. Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score. [Baseline and Day 42]

      PANSS total score measures symptoms of schizophrenia and consists of responses to 30 items: 7 items from the positive subscale (P1-P7), 7 items from the negative subscale (N1-N7) and 16 items from the general psychopathology subscale (G1-G16). Responses to each item range from 1 = absence of symptom, to 7 = most extreme symptoms. The PANSS total score is the sum of the scores for all 30 items, and ranges from 30 to 210, with a higher score indicating greater severity of symptoms. Change from baseline values that are negative represent an improvement in symptoms.

      PANSS General Psychopathology subscale measures symptoms of schizophrenia and consists of responses to 16 items (G1-G16). Responses to each item range from 1 = absence of symptom, to 7 = most extreme symptoms. The PANSS General Psychopathology subscale is the sum of the scores for all 16 items and ranges from 16 to 112, with a higher score indicating greater severity of symptoms.. An improvement in symptoms is represented by change from baseline values that are negative.

    4. Change From Baseline in PANSS Marder Factor Positive Symptom Score. [Baseline and Day 42]

      PANSS Marder Factor Positive symptom score measures symptoms of schizophrenia and consists of responses to 8 items (P1,P3,P5,P6,N7,G1,G9,G12). Responses to each item range from 1 = absence of symptom, to 7 = most extreme symptoms. The PANSS Marder Factor Positive symptom score is the sum of the scores for all 8 items and ranges from 8 to 56, with a higher score indicating greater severity of symptoms. An improvement in symptoms is represented by change from baseline values that are negative.

    5. Change From Baseline in PANSS Marder Factor Negative Symptom Score. [Baseline and Day 42]

      PANSS Marder Factor Negative symptom score measures symptoms of schizophrenia and consists of responses to 7 items (N1,N2,N3,N4,N6,G7,G16). Responses to each item range from 1 = absence of symptom, to 7 = most extreme symptoms. The PANSS Marder Factor Negative symptom score is the sum of the scores for all 7 items and ranges from 7 to 49, with a higher score indicating greater severity of symptoms. An improvement in symptoms is represented by change from baseline values that are negative.

    6. Change From Baseline in PANSS Marder Factor Disorganized Thought Symptom Score. [Baseline and Day 42]

      PANSS Marder Factor Disorganized Thought symptom score measures symptoms of schizophrenia and consists of responses to 7 items (P2,N5,G5,G10,G11,G13,G15). Responses to each item range from 1 = absence of symptom, to 7 = most extreme symptoms. The PANSS Marder Factor Disorganized Thought symptom score is the sum of the scores for all 7 items and ranges from 7 to 49, with a higher score indicating greater severity of symptoms. An improvement in symptoms is represented by change from baseline values that are negative.

    7. Change From Baseline in PANSS Marder Factor Hostility/Excitement Symptom Score. [Baseline and Day 42]

The PANSS Marder Factor Anxiety/Depression symptom score is the sum of the scores for all 4 items and ranges from 4 to 28, with a higher score indicating greater severity of symptoms. An improvement in symptoms is represented by change from baseline values that are negative.

    9. Percentage of Participants Who Were PANSS Responders. [Day 42]

      PANSS total score measures symptoms of schizophrenia and consists of responses to 30 items: 7 items from the positive subscale (P1-P7), 7 items from the negative subscale (N1-N7) and 16 items from the general psychopathology subscale (G1-G16). Responses to each item range from 1 = absence of symptom, to 7 = most extreme symptoms. The PANSS total score is the sum of the scores for all 30 items, and ranges from 30 to 210, with a higher score indicating greater severity of symptoms. The PANSS total score was determined at baseline and then at Day 42, and a participant with a 30% or greater reduction from baseline in PANSS total score at Day 42 was considered a PANSS responder.

    10. Change From Baseline in Clinical Global Impressions -Severity of Illness (CGI-S) Score. [Baseline and Day 42]

      The CGI-S is a score that measures the severity of overall bipolar illness. The score ranges on a scale from 1 to 7, where 1 is normal, and 7 is very severely ill. Change from baseline values that are negative represent an improvement in symptoms.

    11. Percentage of Participants Who Were Clinical Global Impressions - Improvement (CGI-I) Responders. [Day 42]

      The CGI-I is a score on a 7-point scale for assessing the change from preceding phase of overall symptoms of bipolar disorder during the treatment of an acute episode or in longer term illness prophylaxis. Compared to the baseline, the CGI-I score ranges from 1 = very much improved since initiating treatment, to 7 = very much worse since initiating treatment. The CGI-I score was assessed at baseline and Day 42. Compared to the baseline measurement, a CGI-I responder had a score at Day 42 of 3 (minimally improved), 2 (much improved) or 1 (very much improved).

    Title Change From Baseline in PANSS Marder Factor Negative Symptom Score.
    Description PANSS Marder Factor Negative symptom score measures symptoms of schizophrenia and consists of responses to 7 items (N1,N2,N3,N4,N6,G7,G16). Responses to each item range from 1 = absence of symptom, to 7 = most extreme symptoms. The PANSS Marder Factor Negative symptom score is the sum of the scores for all 7 items and ranges from 7 to 49, with a higher score indicating greater severity of symptoms. An improvement in symptoms is represented by change from baseline values that are negative.

Responses to each item range from 1 = absence of symptom, to 7 = most extreme symptoms. The PANSS total score is the sum of the scores for all 30 items, and ranges from 30 to 210, with a higher score indicating greater severity of symptoms. The PANSS total score was determined at baseline and then at Day 42, and a participant with a 30% or greater reduction from baseline in PANSS total score at Day 42 was considered a PANSS responder.

Compared to the baseline, the CGI-I score ranges from 1 = very much improved since initiating treatment, to 7 = very much worse since initiating treatment. The CGI-I score was assessed at baseline and Day 42. Compared to the baseline measurement, a CGI-I responder had a score at Day 42 of 3 (minimally improved), 2 (much improved) or 1 (very much improved).
