Phase 4
Completed
Conditions
Schizophrenia
Schizoaffective Disorder
Registration Number
NCT00304655
Lead Sponsor
Korea Otsuka Pharmaceutical Co., Ltd.
Brief Summary

The purpose of this study is to prove safety and efficacy of aripiprazole.

Detailed Description

This study was designed to prove safety and efficacy of aripiprazole in the treatment of acutely relapsed patients with diagnoses of schizophrenia or schizoaffective disorder in Korea and to confirm the maintenance of efficacy and safety during maintenance period and the changes in emotional factors and social functions.

After administering 15 mg/day of aripiprazole for two weeks, the test may change the dose within the range of 10 mg and 30 mg per day by clinical judgment. (Medication duration: 8 weeks (acute phase) + 18 weeks (maintenance phase)\] + 26 weeks (extension phase), \*total 52 weeks)

  5. Patients who have any of the following neurologic diagnoses: migraine, epilepsy, Parkinson's disease, Alzheimer's disease, multiple sclerosis, residual of stroke, transient cerebral ischemic attacks, "cerebral palsy" or any other condition that requires intermittent or maintenance treatment, or which is manifested by any abnormality on neurologic examination
  6. Patients who must continue to take, or who may potentially need to take, during this study, any of the following concomitant medication, which could cause unwanted drug-to-drug interactions or which could confound the analysis of antipsychotic effectiveness: Tegretol (carbamazepine), Depakene Depakote (valproic acid or sodium valproate or divalproate sodium), Lithium carbonate and lithium citrate

  10. Patients who currently meet the DSM-IV criteria for psychoactive substance dependence or patients with a history of substance or alcohol dependence (according to the DSM-IV criteria) within one month prior to the beginning of the study
  11. Patients having any somatic condition whose symptoms or physical signs could be misinterpreted as signs or symptoms of psychosis or as adverse effects from antipsychotic medications.
  12. Patients with any acute or unstable medical condition requiring pharmacotherapy
