Active clinical trials for "Schizophrenia"

We aim to compare the augmentation of clozapine with ziprasidone or risperidone in a randomized, prospective manner.

This is a 2-year study proposing to examine the effects of aripiprazole on heart health factors such as serum lipids, serum leptin, fasting blood sugar, body weight and blood pressure. This study also examines the safety of switching to aripiprazole with respect to changes in the clinical state, preexisting or emergent side-effects, how the brain processes information and changes in social functioning and quality of life.

This is a two part study designed to evaluate the safety and efficacy of SB-773812 in the treatment of acute schizophrenia. Subjects with acute schizophrenia will be randomized in an adaptive design study to receive placebo, SB-773812 60mg or olanzapine 15mg for 12 weeks in Part A. An interim analysis will be conducted to assess the efficacy and safety of the SB-773812 60mg dose compared with placebo. Based on these data, up to two further doses of SB-773812 will be added to the randomization for Part B.

This study will examine the effectiveness of D-serine in increasing and sustaining the benefits of cognitive retraining in people with schizophrenia.

The purpose of this study is to evaluate the effects of a four-week trial of CX516 900mg tid compared to placebo upon verbal memory, attention and negative symptoms. The AMPA receptor positive modulator, CX516, will be added to a stable dose of clozapine, olanzapine or risperidone in inpatients and outpatients with schizophrenia. The trial is intended to extend and replicate results from our previous placebo-controlled pilot trial of CX516 added to clozapine in which the investigators found improvement in memory and attention (moderate-to-large between group effect sizes) and did not observe serious side effects. Because the investigators' pilot trial also detected at two-week follow-up persistence of cognitive benefits and emergence of a large therapeutic effect upon negative symptoms, this trial will also repeat clinical and cognitive assessments at follow-up, four weeks after completion of the study medication to evaluate persistence and/or strengthening of effects.

The purpose of this study is to provide aripiprazole to schizophrenic outpatients and Community Treated Patients who are currently receiving aripiprazole therapy on another BMS sponsored clinical trial.

This study will evaluate the effectiveness of a health management and supported rehabilitation intervention in treating serious mental illnesses in older people.

This study will determine the effectiveness of clozapine versus olanzapine in treating people with schizophrenia that has not improved with treatment.

People affected by schizophrenia often experience poor concentration, lapses in memory and difficulty with completing tasks; and this set of problems are known as neuro-cognitive deficits. Traditional medications used in the treatment of schizophrenia have not been particularly useful in improving these problems, while the recently introduced medications are expected to be superior in this respect. The proposed research study is designed to assess the effect of two of the new medications (Zyprexa and Seroquel) in improving the neurocognitive deficits associated with schizophrenia.

Treatment with conventional antipsychotics such as haloperidol has little effect or may sometimes even worsen negative symptoms (such as blunted affect, emotional withdrawal, and poor rapport) of schizophrenia. The newer "atypical" antipsychotics agents, such as olanzapine, have shown improvement in the treatment of negative symptoms in acute trials. The purpose of this study is to compare an investigational compound (asenapine) with a marketed agent (olanzapine) in the treatment of stable subjects with persistent negative symptoms of schizophrenia for 6 months. Patients completing this study may be eligible to participate in an extension 6 months of treatment. Patients are required to have stable symptoms prior to entry into study.
