Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score at Week 4
Time Frame: 4 weeks
|
This scale consists of symptom constructs (7 positive, 7 negative, 16 general psychopathology), each to be rated on a 7-point Likert-type scale of severity with 1 being absent to 7 being extreme.
Minimum scores (best outcome) equals 30 (total scale); maximum scores (worst outcome) equals 210 (total scale).
Change is calculated between the baseline visit and Week 4.

Change From Baseline in Clinical Global Impressions-Severity (CGIS) Score at Week 4
Time Frame: 4 weeks
|
The CGI-S is a 7-point scale that requires the clinician to assess how mentally ill the patient is in a specific point in time.
Results indicate participants evaluated at one of the following categories: "1: normal, not at all ill"; "2: borderline mentally ill"; "3: mildly ill"; "4: moderately ill"; "5: markedly ill"; "6: severely ill"; and "7: among the most extremely ill patients".
Results indicate a change in CGI-S score from baseline to Week 4 based on the observed data.
Change is calculated between the baseline visit and Week 4.
