Active clinical trials for "Schizophrenia"

The primary objective of the double blind phase of this study is to evaluate the efficacy and safety of 3 fixed dosages of paliperidone ER (6, 9, and 12 mg/day) compared with placebo in adult patients with schizophrenia.

The purpose of this study is to determine the efficacy (how well the drug works), safety, and side effects of paliperidone palmitate injection compared to placebo in the treatment of the symptoms of schizophrenia in adults. The placebo used in this study was a nutritional substance known as 20% Intralipid emulsion given to patients requiring intravenous feedings.

This study will develop a cognitive behavioral therapy (CBT) program to treat symptoms of post-traumatic stress disorder (PTSD) in people with severe mental illnesses who are treated within community mental health systems.

Evaluation of the antipsychotic efficacy and safety of ziprasidone versus olanzapine, risperidone or quetiapine in patients with schizophrenia, schizoaffective and schizophreniform disorders under naturalistic conditions of clinical practice

Schizophrenia is a brain disease. The primary features of schizophrenia are characterized by Positive symptoms (symptoms that should not be there, inability to think clearly, to distinguish reality from fantasy i.e., hearing voices) and Negative symptoms (a reduction or absence of normal behaviors or emotions, i.e., unable to manage emotions, make decisions and relate to others). Other symptoms include reduced ability to recall and learn new information, difficulty with problem solving, or maintaining productive employment. The symptoms of schizophrenia may be due to an imbalance in chemicals in the brain, primarily dopamine and serotonin, which enables brain cells to communicate with each other. Asenapine is an investigational drug that may help to correct the inbalance in dopamine and serotonin. This is a 6-week trial to test the efficacy and safety of asenapine, compared with placebo, using an active comparator agent (haloperidol) in the treatment of patients with an acute exacerbation of schizophrenia. Patients who complete the 6-week trial will have the option of continuing in an additional one year extension trial.

Prodrome based early intervention with an antipsychotic drug vs. benzodiazepine was applied in patients with first episode schizophrenia after one year neuroleptic maintenance treatment. Two groups of patients were followed over a period of 1 year: one further on under maintenance neuroleptic treatment, the other one after stepwise drug discontinuation.

This study will evaluate the effectiveness of switching medications in decreasing schizophrenia symptoms in individuals who are currently taking an antipsychotic medication for the treatment of schizophrenia.

This study will compare Cognitive Adaptation Training (CAT) to minimal schizophrenia treatment. This study will also determine whether the intensity of CAT can be reduced and still provide benefits to patients with schizophrenia.

The goals of this study are to: Determine the blood levels of intramuscular (IM) olanzapine depot in patients at different points in time after an injection, and compare these levels to the amount of olanzapine in the blood of patients after treated by oral administration with Zyprexa (olanzapine) tablets or by intramuscular administration with Zyprexa IntraMuscular (olanzapine for injection).

The purpose of this study is to characterize olanzapine pharmacokinetics: the inter- and intra- subject variabilities of olanzapine pharmacokinetics; and the potential influence of patient factors such as age, weight, gender, origin, and smoking status on olanzapine pharmacokinetics in adolescents with schizophrenia or bipolar I disorder. This study will also assess the safety of olanzapine delivered orally.
