Purpose

Lurasidone HCl is a compound being developed for the treatment of schizophrenia. This clinical study is designed to test the hypothesis that lurasidone is effective, tolerable, and safe as compared with quetiapine XR short term among acutely psychotic patients with chronic schizophrenia.

Primary Outcome Measures:

Primary Efficacy Endpoint: Mean Change in Total PANSS Score From Baseline to the End of the Double Blind Phase [ Time Frame: Week 6 ]
The PANSS (Positive and Negative Syndrome Scale) is a 30-item scale (range 30-210) designed to assess various symptoms of schizophrenia including delusions, grandiosity, blunted affect, poor attention, and poor impulse control. The 30 symptoms are rated on a 7-point scale that ranges from 1 (absent) to 7 (extreme psychopathology). The PANSS total score consists of the sum of all 30 PANSS items. Higher scores indicate worsening.

Secondary Outcome Measures:

Secondary Outcome: CGI-S From Baseline to the End of the Double-blind Treatment [ Time Frame: 6-Weeks ]
Clinical Global Impression of Severity 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. The scale has a single item measured on a 7 point scale from 1 ('normal', not ill) to 7 (extremely ill).
