Change in Total PANSS (Positive and Negative Syndrome Scale)Score From Baseline to the End of the Double Blind Treatment Period. [ Time Frame: Baseline and 6 weeks ]
The PANSS is a 30-item rating instrument evaluating the presence/absence and severity of positive, negative and general psychopathology of schizophrenia. The scale was developed from the BPRS and the Psychopathology Rating Scale. All 30 items are rated on a 7-point scale (1=absent; 7=extreme). The total score can range from 30 to 210. Lower scores represent less severity of illness.
Secondary Outcome Measures :
CGI-S (Clinical Global Impression - Severity) Change From Baseline to the End of the Double-blind Treatment. [ Time Frame: 6 weeks ]
The CGI-S is a clinician-rated assessment of the subject's current illness state on a 7-point scale, where a higher score is associated with greater illness severity.
