Patients who in their own and/or in the Investigator’s opinion, consider ongoing antipsychotic treatment inadequate, because of insufficient efficacy and/or tolerability. 5. Female patients of childbearing potential must have a negative serum pregnancy test at enrolment and be willing to use a reliable method of birth control, ie, barrier method, oral contraceptive, implant, dermal contraception, long-term injectable contraceptive, intrauterine device, or tubal ligation during the study. 6.

Patients who, in the opinion of the Investigator, pose an imminent risk of suicide or a danger to self or others. 5. History of non-compliance as judged by the Investigator. 6. Evidence of clinically relevant disease, (eg, renal or hepatic impairment, significant coronary artery disease, cerebrovascular disease, viral hepatitis B or C, acquired immunodeficiency syndrome [AIDS] or cancer) or a clinical finding that is unstable or that, in the opinion of the Investigator, would be negatively affected by the investigational product or that would affect the investigational product 7. Clinically significant deviation from the reference range in clinical laboratory test results at enrolment as judged by the Investigator. 8. ECG considered to show cardiac abnormality at enrolment as determined by a central reader cardiologist and confirmed by Investigator as clinically significant. 9. A patient with Diabetes Mellitus (DM) fulfilling one of the following criteria: - unstable DM defined as enrolment glycosylated Hb >8.5% - admitted to hospital for treatment of DM or DM related illness in the past 12 weeks - not under care of physician responsible for patient’s DM care - physician responsible for patient’s DM care has not indicated that patient’s DM is controlled - physician responsible for patient’s DM care has not approved patient’s participation in the study - has not been on the same dose of oral hypoglycemic drug(s) and/or diet for the 4 weeks prior to enrolment (Visit 1). For thiazolidinediones (glitazones) this period should not be less than 8 weeks - taking insulin whose daily dose on one occasion in the past 4 weeks has been more than 10% above or below their mean dose in the preceding 4 weeks Note: If a diabetic patient meets one of these criteria the patient is to be excluded even if the treating physician believes that the patient is stable and can participate in the study. 10. A thyroid-stimulating hormone (TSH) concentration higher than 10% above the upper limit of the normal range of the laboratory used for sample analysis at enrolment, whether or not the patient is being treated for hypothyroidism. 11. Administration of a depot antipsychotic injection within 1 dosing interval (for the depot) before day of switch (Visit 2). 12. Known intolerance, or lack of response to treatment with quetiapine IR or treatment with quetiapine IR within 4 weeks prior to enrolment. 13. Known lack of response to clozapine or treatment with clozapine within 4 weeks prior to enrolment. 14. Patients who have started treatment within 4 weeks prior to enrolment with potent cytochrome 3A4 inducers or inhibitors that could potentially affect the metabolism of quetiapine (eg, inducers: phenytoin, carbamazepine, pentobarbital, rifampin, rifabutin, glucocorticoids, thioridazine, St. John's Wort. inhibitors: ketoconazole (except for topical use), itraconazole, fluconazole, erythromycin, clarithromycin, nefa

Primary Outcome(s)
|
Main Objective: The primary objective is to document the clinical benefit of quetiapine SR after switching from other ongoing antipsychotic treatment, regardless of the reason for the switch.
|
Primary end point(s): The proportion of patients who at Visit 7 (Week 12) have an improved clinical benefit based on assessment of clinical efficacy in combination with assessment of tolerability using the Clinical Global Impression-Clinical Benefit (CGI-CB) score, according to a classification based on the principles outlined in Clinical Global Impression item 3 (CGI item 3). Improvement in clinical benefit is defined as a decrease from baseline in CGI-CB.
|
Secondary Objective: The secondary objective is to document improved tolerability, safety or efficacy after switching to quetiapine SR from other ongoing antipsychotic treatment, regardless of the reason for switch.
