January 7, 2013 updated by: AstraZeneca

A 3 Weeks Open Label Study to Evaluate the Efficacy in Agitation and Safety of Quetiapine Fumarate XR in Treatment of Patients With Acute Schizophrenia

The purpose of the study is to determine whether treatment with quetiapine XR (Seroquel XR) tablets for 3 weeks will improve their agitation when they have acute psychosis.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in Positive and Negative Syndrome Scale Excited Component (PANSS-EC) Score
Time Frame: Baseline and Day 21
PANSS- Excited Component (EC) subscale score will be calculated by adding together the following item scores: excitement (positive subscale item 4); hostility (positive subscale item 7); tension (general subscale item 4); uncooperativeness (general subscale item 8); poor impulse control (general subscale item 14). This is rated on a 7-point Likert scale from 'absent' to 'extremely severe' (score range 5 to 35 points; mean scores = 20 points clinically corresponds to severe agitation). Lower value gives the better outcome.
Baseline and Day 21

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline to Final Visit at Day 21 in PANSS Positive, General Psychopathological Scores.
Time Frame: Baseline and Day 21

Positive scale includes 7 Items (Delusions, Conceptual disorganization, Hallucinations, Hyperactivity, Grandiosity, Suspiciousness/persecution, Hostility)and is calculated by adding the positive subscale item scores. Minimum score is 7, maximum score is 49. General Psychopathology scale: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). Minimum score is 16, maximum score is 112. The higher score- the worse outcome. The biggest reduction of score from baseline- a better efficacy.

Measure includes PANSS-Positive (range 8-30), PANSS-General Psychopathological (PANSS-G)(range 17-70), total PANSS score (range 37-143), PANSS aggression, hostility and depression cluster scores (range 4-19).

Baseline and Day 21
Change From Baseline to Final Visit at Day 21 in PANSS Negative, General Psychopathological Scores
Time Frame: Baseline and Day 21
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. Minimum score is 7, maximum score is 49. General Psychopathology scale includes 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). Minimum score is 16, maximum score is 112. The higher score- the worse outcome. Measure includes PANSS-Negative (range 8-37), PANSS-General Psychopathological (PANSS-G)(range 17-70), total PANSS score (range 37-143), PANSS aggression, hostility and depression cluster scores (range 4-19).
Baseline and Day 21
Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score
Time Frame: Baseline and Day 21
Positive and Negative Syndrome Scale (PANSS) total score is a medical scale used for measuring symptom severity of patients with schizophrenia. It is calculated by adding together PANSS-Positive (minimum score = 7, maximum score = 49, PANSS-Negative (minimum score = 7, maximum score = 49), PANSS-General Psychopathological (PANSS-G) subscale scores (minimum score = 16, maximum score = 112), supplementary subscale item scores. The minimum is 30, maximum is 210. Total PANSS score classification: Mildly ill 58- 74, Moderately ill 75-94, Markly ill 95- 115, Severely ill >116.
Baseline and Day 21
Change From Baseline in Clinical Global Impression-Severity Scale (CGI-S)
Time Frame: Baseline and Day 21

Clinical Global Impression, Severity (CGI-S) is a single-item (7-point) scale that evaluates the overall severity of the subject's mental illness. A reduction in score indicates an improvement in the subject's condition. The CGI-S assessment should be based upon the subject's symptoms during the previous week.

Change from baseline in CGI-S score is calculated by subtracting the CGI-S score at baseline from the CGI-S score at the relevant time point.

Baseline and Day 21
Change From Baseline in Absolute Clinical Global Impression-Improvement (CGI-I) Scale
Time Frame: Baseline and Day 21

Clinical Global Impression, Improvement (CGI-I) is a single-item (7-point) scale that evaluates the overall improvement in the subject's mental. A reduction in score indicates an improvement in the subject's condition. This assessment is based on the improvement since initiation of the study treatment.

Change in CGI-I score is analyzed by comparing CSI-score at the relevant time point to the baseline CGI-I score.

Baseline and Day 21
Change of the Positive and Negative Syndrome Scale Excited Component (PANSS-EC) Score Compared From Baseline to Day 21.
Time Frame: Baseline and Day 21

Excited Component was used to evaluate the control of agitation and aggression in patients with schizophrenia.

Difference in mean score at baseline and day 21 is used to assess the improvement. It is shown by reduction in mean score and confirmed by p value lower than 0,05.

Positive and Negative Syndrome Scale Excited Component (PANSS-EC) is a subscale score which is calculated by adding together the following item scores: excitement (positive subscale item 4); hostility (positive subscale item 7); tension (general subscale item 4); uncooperativeness (general subscale item 8); poor impulse control (general subscale item 14).

This is rated on a 7-point Likert scale from 'absent' to 'extremely severe' (score range 5 to 35 points; mean scores = 20 points clinically corresponds to severe agitation).
