The Brief Assessment of Cognition in Schizophrenia (BACS) is the metric used to characterize cognition in this study. The BACS consists of 6 subscales: Verbal Memory (range 0-75), Working Memory (range 0-28), Motor Speed (range 0-100), Verbal Fluency (measure is total number of words generated in two 60 second trials), Attention and Processing speed (range 0-110), and Executive Function (range 0-22). For each subscale, higher scores reflect better cognition. For each subscale, a Standard Deviation Score was calculated based on normative data (Keefe et al. Norms and standardization of the Brief Assessment of Cognition in Schizophrenia (BACS). Schizophrenia Research 102 (2008) 108-115). The BACS composite score is calculated as the average Standard Deviation Score of the 6 subscale scores. The change in BACS composite score was calculated as the BACS composite score at 8 weeks minus the BACS composite score at baseline. (NCT01696929)
Timeframe: Change in BACS composite score from baseline to 8 weeks

The Positive and Negative Symptoms Scale (PANSS) is the metric used to characterize psychotic symptoms in this study. The PANSS consists of 30 items, each scored 1-7. The range for the PANSS total score is 30-210. There are 3 subscales - PANSS positive score (range 7-49), PANSS negative score (range 7-49), and PANSS general score (range 16-112). PANSS total score is the summation of these 3 subscales. Higher values for the total and subscale scores reflect more severe psychopathology. A positive change in PANSS total score reflects an increase in psychopathology. A negative change in PANSS total score reflects a decrease in psychopathology. (NCT01696929)
Timeframe: Change in PANSS total score from baseline to 8 weeks
