Though the effectiveness of clozapine has been established, a considerable number of patients with schizophrenia are partially responsive or unresponsive to clozapine. In addition, long-term use of clozapine is associated with the development of obsessive-compulsive symptoms and metabolic syndrome. In order to overcome these short-comings and to increase efficacy, aripiprazole augmentation was implemented. Quantitative electroencephalogram will be used to monitor the occurrence of abnormal findings and to analyze the changes in electroencephalographic pattern with linear and non-linear methodology.\n\nComparisons: Design of double-blind randomized placebo controlled study of patients at Refractory Schizophrenia Clinique in Department of Neuropsychiatry at Seoul National University Hospital.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Male or female patients, 18-65 years of age.\n* Patients must have a diagnosis of schizophrenia according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV).\n* Female patients of menarche must be using a medically accepted means of contraception (e.g. oral contraceptives, Depo-Provera, abstinence).\n* Each patient must provide written informed consent after full explanation of study protocol, and authorized legal guardian must understand the nature of the study and must also give assent to study participation.\n* Patients must have a baseline (day 0) BPRS score of at least 35 or over 2 of 5 SANS global rating item scores of at least 3.\n* Patients have been receiving clozapine treatment for more than 1 year and there has been no change in clozapine dosage for more than 3 months.\n* Patients must have a history of antipsychotic treatment with at least 2 different kinds prior to clozapine administration.\n* Subjects who are fluent in Korean.\n\nExclusion Criteria:\n\n* DSM-IV substance (except nicotine or caffeine) dependence within the past 1 year.\n* Female patients who are either pregnant or lactating.\n* Mental retardation (IQ \\< 70).\n* Neurological disorders including epilepsy, stroke, or severe head trauma.\n* Clinically significant laboratory abnormalities, on any of the following tests: CBC with differential, electrolytes, BUN, creatinine, hepatic transaminases, urinalysis and EKG.\n* Prior history of aripiprazole non-response or intolerance.\n* BPRS score of \\< 35 and over 4 of 5 SANS global rating item scores of \\< 3.\n* Participation in a clinical trial of another investigational drug within 3 months (90 days) prior to study entry.\n* Treatment with an injectable depot neuroleptic within less than three dosing interval between the last depot neuroleptic injections and baseline (day 0).\n* History of electroconvulsive therapy within the past 3 months.\n* Subjects who are not fluent in Korean.'}, 'identificationModule': {'nctId': 'NCT00328367', 'briefTitle': 'Aripiprazole Augmentation for Clozapine-Treated Patients With Refractory Schizophrenia', 'organization': {'class': 'OTHER', 'fullName': 'Seoul National University Hospital'}, 'officialTitle': 'A Double-Blind Randomized Placebo Controlled Study of Aripiprazole Augmentation for Clozapine-Treated Patients With Refractory Schizophrenia', 'orgStudyIdInfo': {'id': 'KYS-2006-05209'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'A', 'description': 'clozapine plus aripiprazole', 'interventionNames': ['Drug: aripiprazole']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'B', 'description': 'clozapine plus placebo', 'interventionNames': ['Drug: placebo']}], 'interventions': [{'name': 'aripiprazole', 'type': 'DRUG', 'otherNames': ['abilify', 'OPC-14597'], 'description': 'aripiprazole augmentation of clozapine', 'armGroupLabels': ['A']}, {'name': 'placebo', 'type': 'DRUG', 'description': 'placebo', 'armGroupLabels': ['B']}]}, 'contactsLocationsModule': {'locations': [{'zip': '110-744', 'city': 'Seoul', 'country': 'South Korea', 'facility': 'Seoul National University Hospital', 'geoPoint': {'lat': 37.566, 'lon': 126.9784}}], 'overallOfficials': [{'name': 'Yong Sik Kim, MD, PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Seoul National University Hospital'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Seoul National University Hospital', 'class': 'OTHER'}, 'collaborators': [{'name': 'Korea Otsuka Pharmaceutical Co., Ltd.', 'class': 'INDUSTRY'}], 'responsibleParty': {'oldNameTitle': 'Yong Sik Kim/Professor', 'oldOrganization': 'Seoul National University Hospital'}}}}
