Active clinical trials for "Schizophrenia"

This study aims to examine factors potentially contributing to differences in blood folate, homocysteine or B12 levels between schizophrenia patients, to test the hypothesis that low folate is associated with negative symptoms, and to examine the efficacy of folate supplementation for reducing negative symptoms.

During this study the efficacy and safety profile will be evaluated of the use of amisulpride in the form of a solution in schizophrenic patients with an acute episode. The main purpose of the study is to observe the anti-psychotic effect of amisulpride as a solution during the first days of an acute episode of schizophrenia.

The purpose of the study is to compare the time to relapse in patients with schizophrenia and schizoaffective disorders receiving risperidone or haloperidol (antipsychotic medications) for at least 1 year.

The objective of this study is to demonstrate that there is a benefit in switching chronic schizophrenic patients from conventional antipsychotic to olanzapine in terms of efficacy, neurological safety and patient's outcome.

This study is a placebo-controlled study to assess the safety and tolerability of a novel antipsychotic medication, (773812) when given to schizophrenic patients for twenty-eight days. Assessments include blood sampling to determine drug concentrations, psychiatric assessments while under treatment, and movement assessments to evaluate potential side effects.

Many individuals with schizophrenia smoke cigarettes but little is known about the factors that control smoking in people with schizophrenia. The purpose of this trial is to evaluate how bupropion, an antidepressant medication, affects smoking behaviors in individuals with schizophrenia who smoke.

The purpose of this study is to evaluate symptomatic remission rate in patients with schizophrenia using long acting risperidone microspheres

The purpose of the study is to evaluate the maintained effectiveness of long-acting injectable risperidone (RISPERDAL® CONSTA™) compared with the previous treatment with oral olanzapine in non-acute subjects with schizophrenia or schizoaffective disorder considered in need of a therapy change.

The primary objective of this randomized trial was to investigate whether early initiation of treatment with Risperdal Consta after an acute episode was not inferior to the routine approach (oral treatment for 12 weeks followed by treatment with Risperdal Consta). .

The primary features of schizophrenia and schizoaffective disorder are positive (inability to think clearly and distinguish reality from fantasy) and negative symptoms (reduction or absence of normal behavior or emotions). Other symptoms include reduced ability to recall and learn information, difficulty in problem solving maintaining productive employment. Asenapine is an investigational drug that may help to correct the above schizophrenia by altering the inbalance of brain hormones such as dopamine serotonin. This is a long-term extension trial to further test the efficacy and safety asenapine and a comparator agent (olanzapine) in the treatment of patients with schizophrenia.
