What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Clinical Utility Index (CUI)	CUI measures the efficacy (response), tolerability (time on treatment) and safety [incidence of adverse events (AEs)] by quantifying these 3 attributes and provides a single metric for overall treatment outcome. Each component is given a score ranging from 0 to 5. The CUI Total Score is the sum of the 3 items and ranges from 0 to 15. The greater the CUI Total Score, the more effective the treatment. If a participant experiences a drug-related seizure/death, the safety component is given a score of 0 resulting in an overall CUI Total Score of 0. Analysis of variance (ANOVA) was used to calculate Least Squares (LS) mean and standard error. LS mean values were controlled for treatment, gender and pooled investigators.	Baseline through Week 6

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline to Week 6 Endpoint in the Positive and Negative Syndrome Scale (PANSS) Total Score, Positive Score, Negative Score, and Psychopathology Subscale	The PANSS consists of 30 items and 3 subscales designed to measure severity of psychopathology in schizophrenia. The PANSS Positive Subscale and the PANSS Negative Subscale each contain 7 items, and the remaining 16 items make up the PANSS General Psychopathology Subscale. Each item is rated from 1 (symptom not present) to 7 (symptom extremely severe). The PANSS Total Score is the sum of the 30 items (range from 30 to 210). The PANSS Positive Subscale and PANSS Negative Subscale scores each range from 7 to 49. The PANSS General Psychopathology Subscale score ranges from 16 to 112. Higher scores indicate greater severity of illness. The Mixed Model Repeated Measures (MMRM) analysis was used to calculate Least Squares (LS) mean and 95% confidence interval. LS mean values were controlled for baseline, treatment, gender, pooled investigator, visit, treatment*visit and baseline*visit.	Baseline, Week 6
Change From Baseline to Week 6 Endpoint in the Clinical Global Impression-Severity Scale (CGI-S)	The CGI-S instrument is used to record the severity of mental illness at the time of assessment. The score ranges from 1 (normal, not at all ill) to 7 (among the most extremely ill). Higher scores indicate greater severity of illness. The Mixed Model Repeated Measures (MMRM) analysis was used to calculate Least Squares (LS) mean and 95% confidence interval. LS mean values were controlled for baseline, treatment, gender, pooled investigator, visit, treatment*visit and baseline*visit.	Baseline, Week 6
Change From Baseline to Week 6 Endpoint in the 16-item Negative Symptoms Assessment (NSA-16)	The NSA-16 scale is used to help clinicians rate behaviors (not psychopathology) commonly associated with negative symptoms of schizophrenia. The scale rates participants on 16 "anchors". Each item ("anchor") is rated from 1 (better) to 6 (worse). The NSA-16 Total Score is the sum of the 16 specific items and ranges from 16 to 96. Higher scores indicate greater severity of illness. The Mixed Model Repeated Measures (MMRM) analysis was used to calculate Least Squares (LS) mean and 95% confidence interval. LS mean values were controlled for baseline, treatment, gender, pooled investigator, visit, treatment*visit and baseline*visit.	Baseline, Week 6
The Number of Participants With Treatment-Emergent Suicidal Ideation and Behavior Based on the Columbia Suicide Severity Rating Scale (C-SSRS)	Columbia Suicide Rating Scale (C-SSRS) captures occurrence, severity, and frequency of suicide-related thoughts and behaviors. Suicidal ideation: a "yes" answer to any one of 5 suicidal ideation questions: wish to be dead, and 4 different categories of active suicidal ideation. Suicidal behavior: a "yes" answer to any of 5 suicidal behavior questions: preparatory acts or behavior, aborted attempt, interrupted attempt, non-fatal suicide attempt, and completed suicide. The number of participants with statistically significant changes of the C-SSRS was the number of participants with a treatment-emergent suicidal ideation and behavior (an increase in suicidal behavior or ideation over lead-in baseline.)	Baseline up to Week 6
Percentage of Participants Who Discontinued (Rate of Discontinuation)	Rate of discontinuation was calculated as the number of participants who discontinued from study due to any reason divided by the total number of participants who received study drug, then multiplied by 100.	Baseline through Week 6
