Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of participants with Adverse events | Baseline through 18 weeks post-dose | Adverse events |
| Drug Concentrations | Baseline through 18 weeks post-dose | Concentrations assessed by pre-specified methods |
| Changes from baseline in Positive and Negative Syndrome Scale (PANSS) total score | Baseline through 18 weeks post-dose | PANSS includes 30 items (7 items for positive symptoms, 7 items for negative symptoms, and 16 items for general psychopathology symptoms), and each item ranges from 1 to 7. The PANSS total score is a sum of scores from all items, ranging from 30 to 210, where a higher score represents severer psychotic symptoms in patients with schizophrenia. |
