Active clinical trials for "Schizophrenia"

The major goal of this project is to investigate established insomnia treatments in a schizophrenia population to see if the improved sleep leads to overall better quality of life. In addition, we hypothesize that the insomnia treatment may also lead to observed improvements in other symptoms associated with schizophrenia such as cognitive impairments, obesity, and negative symptoms.

This local registration study is to confirm the hypothesis of the efficacy, tolerability and safety of ziprasidone IM (intramuscular) in the Chinese population with agitation in schizophrenia

The study determines if a new preparation of a drug designed to treat schizophrenia is more slowly released into the body.

We investigate whether the add-on specific antitoxoplasmatic medication has positive effects in individuals with schizophrenia or major depression seropositive for Toxoplasma gondii (TG) infection. As TG modulates neurotransmitter metabolism affecting serotonin and dopamine we hypothesize that this chronic persistent infection might play a role for depressive and psychotic symptomatology. Therefore, on the basis of an ex juvantibus approach, specific anti TG medication might further improve psychiatric symptomatology in affected patients. This is investigated in a double-blind, placebo-controlled, randomized treatment trial.

The purpose of this study is to test the safety and effectiveness of talnetant vs. risperidone vs. placebo in reducing positive and negative symptoms in acutely psychotic schizophrenia patients.

To evaluate the efficacy, safety and tolerance of an 12 and 26-week aripiprazole administration

The purpose of this study is to determine whether cannabidiol, a herbal cannabinoid, is effective in the treatment of acute schizophrenic or schizophreniform psychosis in a placebo-controlled, randomized double-blind study.

This 52 week long study evaluates the effectiveness of aripiprazole versus risperidone in treating people with first-episode schizophrenia. Patients who do not improve with these medications receive clozapine as their third medication trial.

A Multicenter, Double-blind 16 Week Study on the augmentation of atypical antipsychotic with Aripiprazole in patients with Schizophrenia with inadequate response to antipsychotic treatment.

The primary objective of this pilot study is to evaluate the impact of switching 30 subjects from an existing antipsychotic to risperidone long acting on healthcare resource utilization. The study will be a ten month open-label, 'mirror-image', pilot study. Healthcare resource utilization during the 10 months prior to starting risperidone long acting will be retrospectively collected for all subjects (period A) at the beginning of the study. The utilization of direct medical resources will also be collected for 10 months after initiation of risperidone long acting (period B). In this design the patients will serve as their own control.
