What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Measurement of Schizophrenia Symptoms: Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score
Time Frame: Baseline to Week 6
The Positive and Negative Syndrome Scale is a 30-item rating scale specifically developed to asses both the positive and negative symptom syndromes of patients with schizophrenia. The PANSS total score is rated based on a structured clinical interview with the patient and supporting clinical information obtained from family, hospital staff, or other reliable informants. This assessment provides scores in 9 clinical domains, including a positive syndrome, a negative syndrome, depression, a composite index, and general psychopathology. Each item is scored on a 7-point (1 to 7) scale, with 1 being minimal impact, and 7 being highest impact. The cumulative score ranges from 30 to 210. A negative change score indicates improvement.
Baseline to Week 6

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Measurement of Schizophrenia Symptoms: Change From Baseline in Clinical Global Impression-Severity (CGI-S)
Time Frame: Baseline to Week 6
The Clinical Global Impressions-Severity scale is a clinician-rated scale that measures the overall severity of a participant's illness in comparison with the severity of illness in other participants the physician has observed. The participant is rated on a scale from 1 to 7 with 1 indicating a "normal state" and 7 indicating "among the most extremely ill participants." A higher score indicates greater illness. A negative change score indicates improvement.
Baseline to Week 6
