入选标准
- •18 to 65 years of age, inclusive, at the time of informed consent with a diagnosis of schizophrenia as defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) and confirmed by the Mini International Neuropsychiatric Interview (M.I.N.I) for Schizophrenia and Psychotic Disorders Studies
- •Would benefit from hospitalization or continued hospitalization for treatment of a current acute relapse of schizophrenia at trial entry
- •Are experiencing an acute exacerbation of psychotic symptoms and marked deterioration of usual function as demonstrated by all of the following:
- •Positive and Negative Syndrome Scale (PANSS) Total Score of ≥ 80
- •Score of ≥ 4 on two or more of the following PANSS items at screening: hallucinatory behavior, unusual thought content, conceptual disorganization, or suspiciousness
- •Clinical Global Impression - Severity of Illness Scale (CGI-S) score ≥ 4 (moderately ill)
排除标准
- •Are presenting with a first episode of schizophrenia based on the clinical judgment of the investigator
- •Have been hospitalized > 21 days for the current acute episode at the time of the baseline visit
- •Have a current DSM-IV-TR Axis I diagnosis other than schizophrenia, including, but not limited to, schizoaffective disorder, major depressive disorder (MDD), bipolar disorder, post-traumatic stress disorder, anxiety disorders, delirium, dementia, amnestic, or other cognitive disorders; also borderline, paranoid, histrionic, schizotypal, schizoid, antisocial personality disorders or mental retardation.
- •Improvement of ≥ 20% in total PANSS score between the screening and baseline assessments.

结局指标
主要结局
Change From Baseline to Week 6 in Positive and Negative Syndrome Scale (PANSS) Total Score
时间窗: Baseline to Week 6
The PANSS consisted of three subscales: a total of 30 symptom constructs. For each symptom construct, severity was rated on a 7-point scale, with a score of 1 (absence of symptoms) and a score of 7 (extremely severe symptoms). The PANSS total score was the sum of the rating scores for 7 positive scale items, 7 negative scale items, and 16 general psychopathology scale items from the PANSS panel. The PANSS total score ranged from 30 (best possible outcome) to 210 (worst possible outcome).
