Eligibility
Inclusion criteria
Inclusion criteria: For inclusion in the study subjects must fulfil all of the following criteria: 1. Provision of written informed consent prior to enrolment. 2. Men and women age >18 to 4 5. PANSS score of >90 at enrolment visit as well as a score of at least 14 on the PANSS-EC, with a score of at least 4 on at least one of 5 items at both enrolment and randomization visits. 6. Female patients of childbearing potential must have a negative serum pregnancy test enrolment and be willing to use a reliable method of birth control, i.e., barrier method, oral contraceptive, implant, dermal contraception, long-term injectable contraceptive, intrauterine device, or tubal ligation during the study. 7. Be able to understand and comply with the requirements of the study, as judged by the investigator. 8. Patient must be hospitalised during the study. Are the trial subjects under 18? Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range F.1.3 Elderly (>=65 years) F.1.3.1 Number of subjects for this age range
Exclusion criteria
Exclusion criteria: Any of the following is regarded as a criterion for exclusion from the study: 1. Meeting the criteria for any other (than schizophrenia) DSM-IV Axis I disorder not in full remission, concomitant organic mental disorder or mental retardation. 2. Patients with substance dependence. A urine drug screen will be performed. The investigator will evaluate the results along with medical history to determine if the patient meets the DSM-IV criteria for substance dependence. 3. Risk of transmitting HIV or hepatitis B, via blood or other body fluids (as judged by the investigator). 4. Patients who, in the opinion of the investigator, pose an imminent risk of suicide or a danger to self or others. 5. Female patients who are pregnant, lactating or at risk of pregnancy. 6. Patients with a history of non-compliance as judged by the investigator. 7. Evidence of clinically relevant disease [...] or a clinical finding that is unstable or that, in the opinion of the investigator, would be negatively affected by the study medication or that would affect the study medication. 8. Clinically significant deviation from the reference range in clinical laboratory test results at enrolment as judged by the investigator. 9. ECG considered to show clinically significant abnormality at enrolment. 10. A TSH concentration more than 10% above the upper limit of the normal range of the laboratory used for sample analysis at enrolment, whether or not the subject is being treated for hypothyroidism. 11. Administration of a depot antipsychotic injection within 1 dosing interval (for the depot) before randomization day 1. 12. Use of antipsychotic, mood stabilizer, antidepressant, anxiolytic, hypnotic, or other psychoactive drugs within 48 hours before randomization and throughout the randomized period (except medications specified in the protocol) 13. Use of drugs that induce or inhibit the hepatic metabolizing cytochrome 3A4 enzymes within 2 weeks prior randomization [...]

| Main Objective: The primary objective for the study is to evaluate the safety and tolerability of IR (Immediate-Release) quetiapine in a rapid escalation scheme (300 mg on day 1, 600 mg on day 2 and 800 mg on day 3) compared to the current approved label titration (50 mg on day 1, 100 mg on day 2, 200 mg on day 3, 300 mg on day 4, 400 mg on day 5, 600 mg on day 6 and 800 mg on day 7). The safety profile of both titration schemes will be measured with the proportion of patients who discontinue the study treatment due to adverse events (AEs) during the first week (day 1 to day 7) of treatment.;Secondary Objective: 1. To evaluate if the initiation with 300 mg on day 1 is safe and well tolerated in the treatment of severely ill acute schizophrenic patients. 2. To evaluate if increasing the dosing up to 800mg on day 3 is safe and has a similar tolerability to the current label in the treatment of severely ill acute schizophrenic patients. 3. To evaluate if dosing with 800 mg from day 3 to day 7 is safe and has a similar tolerability to the current label in the treatment of severely ill acute schizophrenic patients. 4. To evaluate if there is a comparable safety and tolerability during the 12 days of treatment. 5. To evaluate if there is a comparable safety/tolerability profile between both titration schemes on EPS, measured by SAS and BARS. 6. To evaluate if the faster titration will provide a faster onset of efficacy measured by PANSS-EC, CGI. ;Primary end point(s): Proportion of patients who discontinue the study treatment due to adverse events (AEs) during the first week (day 1 to day 7) of treatment | — |
