Primary | The Number of Patients Who Experienced Adverse Events as a Measure of Safety and Tolerability | Baseline, up to Week 29 | Yes | |
Secondary | Changes in Positive and Negative Syndrome Scale (PANSS) total scores from baseline at each visit between groups or subgroups (with psychiatry history <=5 years or >5 years) | PANSS is used for measuring symptom severity of patients with schizophrenia. PANSS includes a total score (sum of 30 items) and 3 subscale scores including positive subscale (7 items), Negative subscale (7 items) and General psychopathology subscale (16 items). The rank of each scale is rated from 1 point (absent) to 7 points (extreme). | Baseline, Week 25 | No |
Secondary | Changes in Personal and Social Performance (PSP) Scale Scores from Baseline at Each Visit Between Groups or Subgroups (with Psychiatry History <=5 years or >5 years) | PSP scale is used for evaluation of a patient's personal and social functions. PSP is used for degrees of difficulties on four functioning dimensions during previous 1 month: socially useful activities, personal and social relationships, self-care and disturbing and aggressive behaviors. Every dimension is rated (i. absent to vi. very severe). PSP total scores range from 1-100, which are divided into 10 ratings to assess difficulties degrees. Ratings from 71-100 reflect only mild difficulties; ratings from 31-70 reflect manifest disabilities of various degrees; ratings =30 reflect functioning so poor that intensive support or supervision is needed. | Baseline, Week 25 | No |
