NCT00000373	Treatment of Obsessive-Compulsive Disorder	Completed	National Institute of Mental Health (NIMH)	Phase 4	The purpose of this study is to find the best treatment for Tourette's Syndrome (TS)-spectrum obsessive-compulsive disorder (OCD), which includes symptoms of TS, e.g., repeated and involuntary body movements (tics). There are 2 parts to this study: In Part 1, patients are placed into 1 of 2 groups based on type of OCD, determined by medical history and family member interviews. In Part 2, patients are treated with fluvoxamine (FVX) for 8 weeks. If patients do not respond to FVX alone, either haloperidol or an inactive placebo will be added to the FVX regimen; patients will take this drug combination for 4 weeks. Patients will be monitored throughout the trial.

NCT00000374	Treatment for First-Episode Schizophrenia	Completed	National Institute of Mental Health (NIMH)	Phase 4	This 3-year study will determine if the antipsychotic medications olanzapine (Zyprexa®) and risperidone (Risperdal®) can help patients with first-episode schizophrenia.
NCT00000374	Treatment for First-Episode Schizophrenia	Completed	The Zucker Hillside Hospital	Phase 4	This 3-year study will determine if the antipsychotic medications olanzapine (Zyprexa®) and risperidone (Risperdal®) can help patients with first-episode schizophrenia.
NCT00000374	Treatment for First-Episode Schizophrenia	Completed	Northwell Health	Phase 4	This 3-year study will determine if the antipsychotic medications olanzapine (Zyprexa®) and risperidone (Risperdal®) can help patients with first-episode schizophrenia.
NCT00001656	Comparison of Clozapine vs Olanzapine in Childhood-Onset Psychotic Disorders	Completed	National Institute of Mental Health (NIMH)	Phase 4	The purpose of this study is to compare the effectiveness and side effects of the drugs clozapine and olanzapine in children and adolescents with schizophrenia and psychoses. Childhood psychosis is a serious disorder that may have devastating consequences. Effective treatments for the condition are under continual investigation. This study will examine the causes of and offer treatment for childhood psychosis. Participants in this study will undergo psychological tests, blood and urine tests, electroencephalogram (EEG), electrocardiogram (EKG), and magnetic resonance imaging (MRI) scans of the brain for the first 1 to 2 weeks of the study while taking their regular medications. Participants will then be tapered off their medications over 1 to 3 weeks and will continue to stay off medications for an additional 2 days to 3 weeks. During this time, participants will undergo psychiatric, neurological, and cardiac examinations as well as blood tests. After this period without medications, participants will be randomly assigned to receive either clozapine or olanzapine for 8 weeks. An EEG will be performed prior to treatment and after 6 weeks of study medication. Participants who respond well to the study drugs may continue to receive them through their own physician. Participants who do not respond to either clozapine or olanzapine or cannot tolerate their side effects will be treated individually with other drugs until optimum treatment is identified. Regular telephone updates and in person visits to NIH for repeat testing and MRIs will be conducted.
NCT00006195	Glucose Regulation During Risperidone and Olanzapine Treatment	Unknown status	Janssen, LP	N/A	The overall purpose of this research is to look at how two of the most commonly prescribed newer antipsychotic medications, risperidone and olanzapine, affect substances in the body such as glucose and insulin. Undesirable changes in blood sugar control, or glucose regulation, and type 2 diabetes can occur more commonly in individuals with schizophrenia compared to healthy subjects and subjects with other psychiatric conditions. While abnormalities in glucose regulation were first reported in schizophrenia before the introduction of antipsychotic medications, antipsychotic treatment may contribute significantly to abnormalities in glucose regulation. Attention to the way that antipsychotic medications may affect glucose regulation has increased as doctors have become more concerned in general about disease- and drug-related medical complications, including weight gain during antipsychotic treatment.
