Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline in Positive and Negative Syndrome Scale (PANSS) total score | baseline to week 6 of maintenance treatment | The total score is 30-210, higher score is indicative of greater symptomatology. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline in PANSS Positive subscale score | baseline to week 6 of maintenance treatment | The PANSS Positive subscale score is 7-49, higher score is indicative of greater symptomatology. |
| Change from Baseline in PANSS Negative subscale score | baseline to week 6 of maintenance treatment | The PANSS Negative subscale score is 7-49, higher score is indicative of greater symptomatology. |
| Change from Baseline in PANSS General Psychopathology subscale score | baseline to week 6 of maintenance treatment | The PANSS General Psychopathology subscale score is 16-112, higher score is indicative of greater symptomatology. |
| Change from Baseline in Clinical Global Impression-Severity (CGI-S) score | baseline to week 6 of maintenance treatment | CGI-S is 0-7 with higher score is indicative of greater symptomatology |
| The Incidence of Overall AEs | baseline to week 6 of maintenance treatment | — |
