Active clinical trials for "Schizophrenia"

A 1-year outpatient study to test the safety and tolerability of a new medication in the treatment of schizophrenia

A 6-week in-patient and out-patient study to test the effectiveness and safety of a new medication in the treatment of schizophrenia

The primary aim of this study is to determine the feasibility of long-acting injectable naltrexone administration in a clinical trial in patients with SMI who also have a diagnosis of alcohol dependence. Secondary aims include providing a preliminary assessment of the tolerability and safety of long-acting injectable naltrexone as compared with oral naltrexone in patients with SMI who also have a diagnosis of alcohol dependence. An additional aim is to provide a preliminary assessment of the efficacy of long-acting injectable naltrexone as compared with oral naltrexone in reducing alcohol use from baseline levels

We are conducting this study to find out if blocking or partially stimulating the effects of nicotine in the brain can affect memory and concentration. Nicotine is the addictive drug found in tobacco products. Our subjects will be people with and without mental illness (schizophrenia), smokers and non-smokers. We will use a medication called mecamylamine (Inversine) to block the effects of nicotine on the brains of our subjects. We will also use a medication called varenicline (Chantix) to partially increase the effects of nicotine on the brains of our subjects. This study also uses a placebo, a pill that does not have any active ingredients but looks exactly like the mecamylamine and varenicline pills. We will compare the effects of giving mecamylamine or placebo to people who have schizophrenia and people who do not have schizophrenia. We know that people with schizophrenia smoke heavily and find it harder to stop smoking than most other people do. Studies have shown that people with schizophrenia may smoke more because nicotine helps their concentration and memory. We are interested in helping people with schizophrenia smoke less. Mecamylamine blocks the parts of the brain that react to nicotine and varenicline partially stimulates and partially blocks the parts of the brain that react to nicotine. Both medications may decrease the effects that smoking has on the body.

This study will determine the effectiveness of a peer support system in increasing physical activity and effecting health behavior change in people with serious mental illnesses.

This is an extension study of A7501013 (P05771/NCT00145496) to further test the efficacy and safety of Asenapine compared with a marketed agent (olanzapine) in the treatment of patients with persistent negative symptoms of schizophrenia.

This study is to determine the efficacy (how well the drug works), safety, and any side effects of olanzapine compared to placebo in the treatment of schizophrenia in adolescents. Both the potential benefits and side effects of olanzapine will be evaluated throughout this trial.

This study will determine whether adding the drug risperidone (Risperdal®) is more effective than placebo in treating schizophrenic patients who are taking the drug clozapine.

The purpose of this study is to test the long-term safety and tolerability of aripiprazole in adolescent patients with schizophrenia, and child and adolescent patients with bipolar I disorder, manic or mixed episode.

The purpose of this study is to demonstrate superior efficacy of sustained release quetiapine compared to placebo in patients with schizophrenia after receiving treatment for up to 6 weeks.
