Active clinical trials for "Schizophrenia"

Adjuvant N-methyl-D-aspartic acid (NMDA)-enhancing agents, such as GlyT-1 inhibitors and NMDA-glycine site agonists have been demonstrated to be beneficial for chronic schizophrenia patients. The purpose of this study is to evaluate efficacy and safety of add-on treatment of an inhibitor of D-amino acid oxidase (DAAOI), DAAOI-1, in chronically stable schizophrenia patients who have been stabilized with antipsychotics.

The study is designed to evaluate the effectiveness of computerized cognitive skills training for improving memory and problem-solving skills in inpatients with schizophrenia.

This study seeks to examine the effectiveness of citalopram added to treatment with any oral or injectable second-generation antipsychotic plus standardized psychoeducation in first episode schizophrenia patients. Because depressive symptoms are common in first episode patients, we will test the hypothesis that adding the SSRI citalopram to a pre-established medication regimen will improve quality of life and decrease relapse and suicidality over the course of a 12-month trial.

The purpose of this study is to evaluate effectiveness, tolerability (how well a participant can stand a particular medicine or treatment), and safety of flexible-dose of paliperidone extended release (ER) in participants with schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self), previously taking risperidone (an antipsychotic), but who are not satisfied with their treatment.

This study aims to evaluate whether PF-02545920 is safe and effective in the treatment of acute exacerbation of schizophrenia during a 4-week inpatient treatment period. The study will use the Positive and Negative Syndrome Scale (PANSS) to measure change in symptoms for PF-02545920 compared to risperidone and placebo treatment.

Randomized, controlled, double-blind, two-armed clinical investigation to show the efficacy and safety of transcutaneous vagus nerve stimulation (t-VNS), applied at the left auricle, in schizophrenia. Study hypothesis: t-VNS may improve negative symptoms, depressive symptoms, cognitive impairment,and aggressive behavior of treated schizophrenia patients.

The investigators will test the hypothesis that the sleep medication, eszopiclone, can normalize brain activity during sleep and improve memory in patients with schizophrenia. The investigators will do this by measuring sleep and memory performance on two conditions separated by one week: taking 3 mg of eszopiclone and taking placebo. The investigators will study healthy subjects and chronic, medicated outpatients with schizophrenia.

The phase 3 Trial 31-12-291 is part of the aripiprazole IM depot clinical development program and has been designed to demonstrate the efficacy and safety of aripiprazole IM depot for the treatment of adults experiencing an acute relapse of schizophrenia. Subjects receive treatment during a 12-week double-blind acute treatment phase. The current trial (31-12-297) will allow the subjects who complete Trial 291 to enter this open label trial at the investigator's discretion, where additional safety and tolerability data will be collected.

The purpose of this study is to determine if Ending Self-Stigma (ESS), a 9-session group intervention designed to assist veterans with serious mental illness to develop skills (SMI) to effectively cope with stigma and minimize the internalization of stigmatizing beliefs and stereotypes, is more effective in reducing internalized stigma and its associated effects than an active comparison group.

This study is designed with the aim to evaluate the clinical effect of the overlapped switching to ziprasidone as well as the efficacy and safe metabolic profile of ziprasidone.
