E.2.1 | Main objective of the trial |
The primary objective of this study is to show superiority of bifeprunox to placebo with regard to time to impending deterioration. |
|
E.2.2 | Secondary objectives of the trial |
- To compare long-term safety in terms of cardiovascular risk factors (weight, waist circumference, fasting blood lipids, HbA1c, fasting blood glucose, blood pressure) of bifeprunox to that of placebo and quetiapine - To determine and compare the long-term effect on functional outcomes, quality of life and treatment adherence of bifeprunox to that of placebo and quetiapine

The subject has/has had a current diagnosis or history of substance (except nicotine, caffeine) or alcohol abuse based on DSM-IV TR criteria within six months prior to Screening. 10. The subject has a positive urine drug screen at screening with the exception that positive result for opioids, cannabinoids and benzodiazepines will be evaluated by the Investigator and sponsor medical expert on the potential impact for study participation. 11. The subject has a history of severe drug allergy or hypersensitivity, or known hypersensitivity to or has other contraindications to serotonergic agents, dopamine antagonists or dopamine agonists. 12. The subject has within 2 months prior to Screening received antidepressants or mood-stabiliser (specified in Appendix II). 13. The subject uses disallowed medication (specified in Appendix II, or it is anticipated that the subject will require treatment with at least one of the disallowed concomitant medications during the study). 14. The subject has a clinically significant unstable illness, for example, hepatic or renal insufficiency, or a cardiovascular, pulmonary, gastrointestinal, endocrine, neurological, infectious, neoplastic, haematological, autoimmune or metabolic disturbance other than those originating from the antipsychotic treatment. Adequately treated hypertension is not considered an exclusion criterion. 15.

The abnormal value should be confirmed at two separate measurements. 18. The subject has a history of repeated vasovagal syncope. 19.
