Study Details
Study Description
Brief Summary
This will be a phase IV 20 -32 day prospective, double blind, double-dummy, randomised crossover study that will evaluate the effect of quetiapine XR and quetiapine IR on cognitive performance in patients with schizophrenia stabilized on a single antipsychotic medication.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Active Comparator: First Seroquel XR then Seroquel IR Patients randomised to Seroquel XR will have treatment for 10-16 days and after that cross-over to treatment with Seroquel IR for 10-16 days |
Drug: Seroquel XR- quetiapine fumarate extended release
Seroquel XR dose 400-700 mg (in tablet form). The investigator established the dosing schedule for each patient depending on the patient's dose when entering the study. The patients continued on the same dose during the study as they had prior to enrolment. Dose taken once a day for 10-16 days.
Drug: Seroquel IR - quetiapine fumarate
Seroquel IR dose 400-700 mg (in tablet form). The investigator established the dosing schedule for each patient depending on the patient's dose when entering the study. The patients continued on the same dose during the study as they had prior to enrolment. Dose taken twice a day for 10-16 days.
Drug: Placebo matching Seroquel XR
Placebo matching Seroquel XR dose 400-700 mg (in tablet form). Dose taken once a day for 10-16 days.
Drug: Placebo matching Seroquel IR
Placebo matching Seroquel IR dose 400-700 mg (in tablet form). Dose taken twice a day for 10-16 days.

Outcome Measures
Primary Outcome Measures
- Mean for Attentional Standardised Composite Score Based on Performance Scores From the CogState Test Battery Domains Detection (Speed of Processing)and Identification (Attention/Vigilance) [Period 1 at 3 visits,(post 1),(post 2),(post 3), in a 5-day (maximum 8 day) period. Period 2 at 3 visits,(post 1),(post 2),(post 3), in a 5-day (maximum 8 day) period.]
Attentional standardised composite score: Standardised speed of performance score. Higher Score=better performance. Score range minus infinity to plus infinity. Measured at baseline (before study drug administration) and in Period 1 at 3 visits,(post 1),(post 2),(post 3), in a 5-day (maximum 8 day) period. (Last test day not earlier than after 10 days of randomised)and in Period 2 at 3 visits,(post 1),(post 2),(post 3), in a 5-day (maximum 8 day) period. Last test day not earlier than after 10 days of crossover treatment.
Secondary Outcome Measures
- Mean Treatment Satisfaction for Treatment Satisfaction Questionnaire of Medication (TSQM) [Before taking study drug, end of Period 1 and end of Period 2]
TSQM is a 14-item questionnaire with 4 sub-scales: effectiveness of the medication; treatment side effects; convenience of the medication; global satisfaction with the medication. Scale range 0-100 for each sub-scale, higher=greater satisfaction/milder side effects/greater convenience/greater overall satisfaction. There are 2 measurement, (after the start of taking study drug) one at end of period 1 and one at end of period 2. That is one measurement per patient per treatment. The mean of all the patients is presented, one mean value per treatment group.
- Mean Daytime Cognitive Performance Using CogState: - Working Memory - Verbal Learning) -Reasoning and Problem Solving [Period 1 at 3 visits,(post 1),(post 2),(post 3), in a 5-day (maximum 8 day) period. Period 2 at 3 visits,(post 1),(post 2),(post 3), in a 5-day (maximum 8 day) period.]
International Shopping List Task (ISLT): measures reasoning and problem solving. Min=minus infinity, max=plus infinity, higher score=better performance. Groton Maze Learning Test (GMLT): measures reasoning and problem solving. Min=minus infinity, max=plus infinity, lower score=better performance. Lower=better performance. One Back memory task (ONB: measures working memory, min=minus infinity, max=plus infinity, lower score=better performance.
- Mean Overall Sedation as Measured by the Modified Bond-Lader Visual Analogue Scale (VAS) When Administered According to Label [Period 1 at 3 visits,(post 1),(post 2),(post 3), in a 5-day (maximum 8 day) period. Period 2 at 3 visits,(post 1),(post 2),(post 3), in a 5-day (maximum 8 day) period.]
The modified Bond-Lader VAS: The degree of sedation was marked by the patient on a 100 mm VAS ranging between Alert (=0 mm) and Drowsy (=100 mm). The marked length in millimetres. There are 3 assessments made in each period (post 1, 2 and 3 for each period). That is three measurements per patient per treatment. The mean is an overall mean of all the recordings in all patients, one mean value per treatment group.
- Mean Overall Sedation as Measured by the Stanford Sleepiness Scale When Administered According to Label [Period 1 at 3 visits,(post 1),(post 2),(post 3), in a 5-day (maximum 8 day) period. Period 2 at 3 visits,(post 1),(post 2),(post 3), in a 5-day (maximum 8 day) period.]
Stanford Sleepiness Scale: The sleepiness was assessed by the patient on a 7 item rating scale ranging from 1 (Feeling active and vital) to 7 (Almost in reverie). There are 3 assessments made in each period (post 1, 2 and 3 for each period). That is three measurements per patient per treatment. The mean is an overall mean of all the recordings in all patients, one mean value per treatment group.
- Number of Dropouts. [Period 1 and Period 2]
The number of patients who dropped out was counted.
- Mean Ratio of Morning Plasma Concentration of Quetiapine and Nor-quetiapine for Quetiapine IR and Quetiapine XR, at Steady-state Conditions in the End of Each Treatment Period 1 and 2. [End of Period 1, end of Period 2]
The ratio was derived as individual plasma concentration of quetiapine divided by the plasma concentration of nor-quetiapine. The mean ratio was derived for each treatment, XR and IR, respectively.
