Active clinical trials for "Schizophrenia"

The purpose of this study is to evaluate the efficacy and safety of long acting injectable (LAI) risperidone and oral risperidone treatment on participants with schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self) or schizoaffective disorder (a mixed psychiatric disorder relating to a complex psychotic state that has features of both schizophrenia and a mood disorder such as bipolar disorder).

The GiSAS study is a multi-centre randomized clinical trial that will involve about 80 italian community psychiatric services in Italy and will recruit 800 patients affected by schizophrenia. In a sample of schizophrenic outpatients, it is hypothesized that there are significant differences in the overall tolerability and effectiveness of aripiprazole, olanzapine and haloperidol at 12 months. It is a pragmatic trial. Thus, participants are selected to represent a broad range of "real-world" patients, all treatment medications are non-blinded and after randomization, the assigned drugs will be prescribed according to usual care practice. The measure for effectiveness is retention of patients on the assigned treatment. The measure for tolerability is the onset of metabolic syndrome.

An inpatient/outpatient study to see if LY2140023 is better than placebo in acutely ill patients with schizophrenia.

The purpose of this study is to assess the long-term safety, tolerability and efficacy of oral OPC-34712 as monotherapy in adults with schizophrenia.

This multi-center, randomized, double-blind, parallel-group, placebo-controlled study will evaluate the efficacy and safety of RO4917838 in participants with persistent, predominant negative symptoms of schizophrenia. Participants, on stable treatment with antipsychotics, will be randomized to receive daily oral doses of RO4917838 or matching placebo for 56 weeks (treatment period 1 of 24 weeks and treatment period 2 of 32 weeks), followed by an optional treatment extension for up to 3 years. After 52 weeks, participants who were originally randomized to an active treatment will be randomly assigned to receive either placebo or continue on the originally assigned study treatment for 4 weeks washout period (Week 52 to Week 56) for the assessment of potential withdrawal effects in a blinded manner using participants staying on active treatment as a control. Participants initially randomized to placebo will remain on placebo. After 56 weeks, participants who were switched to placebo in the washout period will return to their blinded, active treatment arm.

A multicenter, randomized, parallel-group, double-blind, fixed dose, 6-week trial of the efficacy and safety of asenapine compared with placebo in participants with an acute exacerbation of schizophrenia.

These results suggest that the DA neuroprotection provided by DM in the inflammation-related neurodegenerative models is not mediated through the NMDA receptor.

The purpose of this study is to evaluate the long term safety of flexible doses (50 to 150 mg equivalent) of paliperidone palmitate in the treatment of patients with schizophrenia and to document the pharmacokinetics of paliperidone following fixed multiple intramuscular injections of paliperidone palmitate 150 mg eq.

This study is to evaluate the safety and efficacy of the study drug compared to placebo in the treatment of cognitive impairment in men with schizophrenia.

The purpose of this study is to evaluate improvement and efficacy of paliperidone extended-release for subjective well-being and drug attitudes of participants, when switching from oral antipsychotics in participants with schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self).
