| Sample size for this study was based on changes in the MSQ scores within subjects from baseline to endpoint using a one-sample paired t-test. A sample size of 97 subjects was shown to have 90% power at endpoint to detect a mean change from baseline of 0.5 units on the MSQ score, with a standard deviation of 1.5. Allowing for extra variability from subjects with prior generic risperidone (instead of branded risperidone) use, this number was increased to 150 subjects. | t-test, 2 sided | | <0.001 | p-value based on a paired t-test for a within-group comparison. | Mean Difference (Final Values) | 2.4 | Standard Deviation | 1.4 | | | | | | | | No | |

| Other Pre-specified | Positive and Negative Syndrome Scale (PANSS) Total Score Change From Baseline to Week 6 Endpoint | The PANSS is a 30-item scale designed to capture numerous symptoms of schizophrenia, including delusions, grandiosity, blunted affect, poor attention, and poor impulse control. The 30 symptoms are rated on a 7-point scale as follows: 1=Absent, 2=Minimal, 3=Mild,4=Moderate, 5=Moderate Severe, 6=Severe, 7=Extreme. This scale has been shown to be sensitive to changes associated with medication treatment. In addition to a total score, this assessment yields separate scores along a Positive Syndrome, a Negative Syndrome, and a General Psychopathology Scales. Worst value is 210, best value is 30. | Intent-to-Treat Population with non-missing values at this timepoint | Posted | | Mean | Standard Deviation | Points on a scale | | Change from Baseline to Week 6 LOCF | | | | ID | Title | Description |

| Secondary | Pittsburgh Sleep Quality Index (PSQI) Change From Baseline to the Week 6 Endpoint | The PSQI is a 2-part questionnaire that assesses sleep quality and disturbances in seven domains: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleep medication, and daytime dysfunction. Each domain is rated on a 4-point scale as follows: 0=Not during the past month, 1=Less than once a week, 2=Once or twice a week, 3=Three or more times a week. Total scores range from zero to 21; increasing scores indicate poorer sleep quality and total scores greater than 5 suggest significant sleep disturbance. | Intent-to-Treat Population with non-missing values at this timepoint | Posted | | Mean | Standard Deviation | Points on a scale | | Change from Baseline to Week 6 LOCF | | | | ID | Title | Description |

Each dimension is assessed in 5 to 10 minutes using a 5-point scale as follows: 1=Not at all, 2=Somewhat, 3=Moderately, 4=Considerably, to 5=Very much. For this study, the standard COVI Anxiety Scale was modified to improve psychometric properties by incorporating anchor points for symptom severity, frequency, and duration and for functional impairment.
