Effects of 'Seroquel-XR' on the Improvement of Neurocognitive Function in People At-risk Mental States(ARMS)

Study Overview
=================
Brief Summary
-----------------
The primary objective of this study is to assess the effects of 'Seroquel-XR' on the verbal learning ability in people with at-risk mental state (ARMS) over a 12 week period. The verbal learning ability will be indexed by delayed free recall score of CVLT(California Verbal learning Test), a standard neuropsychological verbal memory tests. The secondary objective is to assess the effects of 'Seroquel-XR' on other cognitive function and psychiatric symptoms including psychotic, anhedonic symptoms, and impulsivity. The cognitive function abilities will be measured by standard neuropsychological tests as follows; Working memory: verbal & spatial 2-back test Attention: Digit Span, 3-7 CPT(Continuous Performance Test) Executive function: WCST (Wisconsin Card Sorting Test) Visuo-spatial ability: Rey Complex Figure Task copy Visuomotor speed and planning: Trail making test A & B Verbal fluency: Controlled Oral Word Association Test(COWAT) The scales of psychiatric symptoms which will be used are as follows; Psychotic symptoms: Scales of Prodromal scales (SOPS), Positive and negative syndrome scale (PANSS) Anhedonia: Social Anhedonia Scale (SAS), Physical Anhedonia Scale (PAS) Social cognition: Ambiguous Intention Hostility Questionnaire (AIHQ) Impulsivity: Barrett Impulsivity Scale (BIS)

Eligibility Criteria
-----------------
Inclusion Criteria: Provision of written informed consent Male and female aged 20 to 35 years Able to understand and comply with the requirements of the study ARMS: Female patients of childbearing potential must be using a reliable method of contraception and have a negative urine human chorionic gonadotropin (HCG) test at enrolment ARMS was diagnosed by Structured Interview for Prodromal Syndrome (SIPS) . Schizophrenia subjects: 4. Schizophrenia was diagnosed by Diagnostic and Statistical Manual of Mental Disorders- Fourth Edition (DSM-IV). Patients with schizophrenia had to have been ill no more than 5 years. Subjects had to be clinically stable and on stable antipsychotic therapy for at least 4 weeks prior to baseline study. Normal control: 4. Healthy volunteers who had no history of psychiatric illness and had no first degree relative with psychotic symptoms were included for normal controls. Exclusion Criteria: Pregnancy or lactation Any DSM-IV Axis I disorder not defined in the inclusion criteria. However, in the case of ARMS, psychotic disorder NOS, major depressive disorder, obsessive-compulsive disorder, and social phobia would be allowed. Patients who, in the opinion of the investigator, pose an imminent risk of suicide or a danger to self or others Known intolerance or lack of response to quetiapine fumarate, as judged by the investigator Use of any of the following cytochrome P450 3A4 inhibitors in the 14 days preceding enrolment including but not limited to: ketoconazole, itraconazole, fluconazole, erythromycin, clarithromycin, troleandomycin, indinavir, nelfinavir, ritonavir, fluvoxamine and saquinavir Use of any of the following cytochrome P450 3A4 inducers in the 14 days preceding enrolment including but not limited to: phenytoin, carbamazepine, barbiturates, rifampin, St. John's Wort, and glucocorticoids Administration of a depot antipsychotic injection within one dosing interval (for the depot) before randomisation Substance or alcohol dependence at enrolment (except dependence in full remission, and except for caffeine or nicotine dependence), as defined by DSM-IV criteria Opiates, amphetamine, barbiturate, cocaine, cannabis, or hallucinogen abuse by DSM-IV criteria within 4 weeks prior to enrolment Medical conditions that would affect absorption, distribution, metabolism, or excretion of study treatment Unstable or inadequately treated medical illness (e.g. congestive heart failure, angina pectoris, hypertension) as judged by the investigator Involvement in the planning and conduct of the study Previous enrolment or randomisation of treatment in the present study. Participation in another drug trial within 4 weeks prior enrolment into this study or longer in accordance with local requirements A patient with Diabetes Mellitus (DM) fulfilling one of the following criteria: Unstable DM defined as enrolment glycosylated hemoglobin (HbA1c) more than 8.5 percent. Admitted to hospital for treatment of DM or DM related illness in past 12 weeks. Not under physician care for DM 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 hypoglycaemic drug(s) and(or) diet for the 4 weeks prior to randomisation. 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 percent 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. An absolute neutrophil count (ANC) of 1.5 folded 109 per liter
