Primary Outcome Measures :

1. Measurement of Schizophrenia Symptoms: Positive and Negative Syndrome Scale (PANSS) Total Score [ Time Frame: Baseline to Day 28 ]
   PANSS total score comprises Positive (Delusions, Conceptual disorganization, Hallucinatory behavior, Excitement, Grandiosity, Suspiciousness/persecution, Hostility), Negative (Blunted affect, Emotional withdrawal, Poor rapport, Passive/apathetic social withdrawal, Difficulty in abstract thinking, Lack of spontaneity and flow of conversation, Stereotyped thinking), and General Psychopathology (Somatic concern, Anxiety, Guilt feelings, Tension, Mannerisms and posturing, Depression, Motor retardation, Uncooperativeness, Unusual thought content, Disorientation, Poor attention, Lack of judgment and insight, Disturbance of volition, Poor impulse control, Preoccupation, Active social avoidance) Scales. Scores are obtained by adding the ratings of each item in each scale. Range is 7-49 for Positive and Negative scores; 16-112 for General Psychopathology score; and 30-210 for Total score. Higher score reflects worse outcome; larger reduction from baseline reflects better outcome.

Secondary Outcome Measures :

1. Demonstrates Antipsychotic Efficacy as Assessed by Change From Baseline on the Clinical Global Impression Scale - Severity (CGI-S) [ Time Frame: Baseline to Day 28 ]
   Clinical Global Impression, Severity (CGI-S) is a single-item (7-point) scale that evaluates the overall severity of the subject's mental illness. Scores range from 1 (not ill at all) to 7 (among the most extremely ill). A reduction in score indicates an improvement in the subject's condition.
2. Demonstrates Antipsychotic Efficacy as Assessed by Change From Baseline on the PANSS Positive Subscale [ Time Frame: Baseline to Day 28 ]
   The Positive Scale includes 7 Items (Delusions, Conceptual disorganization, Hallucinations, Hyperactivity, Grandiosity, Suspiciousness/persecution, Hostility) and is calculated by adding the subscale item scores to obtain results ranging from 7 to 49. A higher score reflects worse outcome and a larger reduction in the score from baseline reflects better treatment efficacy.
3. Demonstrates Antipsychotic Efficacy as Assessed by Change From Baseline on the PANSS Negative Subscale [ Time Frame: Baseline to Day 28 ]
   The Negative Scale includes 7 items (Blunted affect, Emotional withdrawal, Poor rapport, Passive/apathetic social withdrawal, Difficulty in abstract thinking, Lack of spontaneity and flow of conversation, Stereotyped thinking) and is calculated by adding the negative subscale item scores to obtain results ranging from 7 to 49. Minimum score is 7, maximum score is 49. A higher score reflects worse outcome and a larger reduction in the score from baseline reflects better treatment efficacy.
4. Demonstrates Antipsychotic Efficacy as Assessed by Change From Baseline on the PANSS General Psychopathology Subscale [ Time Frame: Baseline to Day 28 ]
   The General Psychopathology Scale consists of 16 items (Somatic concern, Anxiety, Guilt feelings, Tension, Mannerisms and posturing, Depression, Motor retardation, Uncooperativeness, Unusual thought content, Disorientation, Poor attention, Lack of judgment and insight, Disturbance of volition, Poor impulse control, Preoccupation, Active social avoidance). The General Psychopathology score is obtained by adding the ratings of each item in the scale, with results ranging from 16 to 112. A higher score reflects worse outcome and a larger reduction in the score from baseline reflects better treatment efficacy.
