E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to show superior efficacy of fixed doses of bifeprunox (20 mg/day) versus placebo following 12 weeks of treatment in subjects with schizophrenia inadequately controlled in the maintenance phase.
|
|
E.2.2 | Secondary objectives of the trial |
Key secondary objective: To show non-inferior efficacy of fixed doses of bifeprunox (20 mg/day) versus fixed doses of quetiapine (600 mg/day) following 12 months of treatment in subjects with schizophrenia inadequately controlled in the maintenance phase. Other secondary objectives: To compare the safety and tolerability of 12 weeks treatment with fixed doses of bifeprunox (20 mg/day) to that of placebo and quetiapine (600 mg/day) To compare the safety and tolerability of 12 months treatment with fixed doses of bifeprunox (20 mg/day) to that of quetiapine (600 mg/day) To determine and compare the effect on functional outcomes, quality of life and treatment compliance of 12 weeks treatment with fixed doses of bifeprunox (20 mg/day) to that of placebo and quetiapine (600 mg/day) To determine and compare the effect on functional outcomes, quality of life and treatment compliance of 12 months treatment with fixed doses of bifeprunox (20 mg/day) to that of quetiapine (600 mg/day)

E.3 | Principal inclusion criteria |
The subject has a primary diagnosis of schizophrenia according to current Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM-IV-TR: codes 295.10, 295.20, 295.30, 295.60, 295.90). .The subject has a CGI-S score of ³ 4 (moderately ill) at screening and baseline. ·The subject has a PANSS total score ³ 60 at screening and baseline. ·The subject is either an inpatient, partially hospitalised, or outpatient for whom the centre can document at least monthly contacts (personal or by telephone) during a minimum of 3 months prior to screening. ·The subject’s antipsychotic treatment has been kept as follows: -At screening: the antipsychotic medication(s) has/have remained the same within 8 weeks prior to screening -At baseline: the antipsychotic medication(s) has/have not been changed (agent(s) and dose(s) between screening and baseline. ·The subject is in a maintenance phase and has not had an acute exacerbation according to the investigator’s judgement. -At screening: within 8 weeks prior to screening -At baseline: between screening and baseline (4 weeks). -The subject has a primary diagnosis of schizophrenia according to current Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM-IV-TR: codes 295.10, 295.20, 295.30, 295.60, 295.90).
