Active clinical trials for "Schizophrenia"

The goal of this project, which has not changed, is to evaluate the statewide implementation of a two-component intervention (health promotion plus academic detailing) with respect to consumer outcomes and changes in provider prescribing. The intervention, called In SHAPE, is delivered to people with serious mental illness (SMI) by two community mental health clinics (CMHCs). These CMHCs are compared to two CMHCs delivering usual-care to individuals with SMI. The specific aims of this study are: Evaluate person-level and provider-level outcomes including: (a) consumer health behaviors, health indicators, mental health indicators, and acute health service utilization, (b) provider prescribing practices and program fidelity, and (c) program costs. Evaluate system-level outcomes including: (a) consumer health behaviors and health indicators, (b) provider prescribing and program fidelity, and (c) acute services use.

Task sharing mental health care through integration of mental health into primary health care (PHC) is advocated as a means of narrowing the treatment gap for mental disorders in low-income countries. In Ethiopia, it is estimated that only around 10% of people with severe mental disorders (SMDs) ever receive evidence-based treatment for their condition, largely due to scarcity of specialist mental health services. A task-sharing model of mental health care in PHC would be more affordable and accessible to the majority of persons with SMD who do not currently receive evidence-based mental health care. Furthermore, task sharing mental health care with PHC is about to be scaled up in Ethiopia in line with the National Mental Health Strategy. However, the effectiveness of the task sharing model of mental health care for people with SMD has not been evaluated systematically in a low-income country. In this study we propose to investigate non-inferiority of a task sharing model of mental health care in PHC compared to a less accessible, but more specialist, psychiatric nurse-led model of care. The specialist model of care has been demonstrated to be acceptable and associated with improved clinical outcomes for persons with SMD engaged in the service in Ethiopia thus making this an appropriate comparison model against which to evaluate non-inferiority of the task sharing model.

The investigators programme of research will evaluate an existing physical health care screening intervention with the aim of helping Community Psychiatric Nurses (CPN) to improve the physical health wellbeing of people with a SMI. This pilot clustered randomised controlled trial aims to establish the potential efficacy and acceptability of the Chinese Health Improvement Profile (CHIP) in improving the physical health of people with severe mental illness.

This study will evaluate the effect of 8 doses of intranasal oxytocin or placebo on two proposed measures of target engagement in brain. The targets are (1) the suppression of a particular wave form (mu) on the electroencephalogram (EEG) while subjects observe a socially relevant form of motion and (2) pupil dilation will subjects identify faces showing different emotions.

To evaluate the pharmacokinetic (PK) characteristics after multiple oral administration of 40 mg lurasidone in healthy Chinese subjects. To evaluate the safety and tolerance after multiple oral administration of 40 mg lurasidone in healthy Chinese subjects.

Impairments in plasticity and working memory in schizophrenia have been hypothesized to reflect dysfunction at the N-methyl-D-aspartate glutamate receptor (NMDAR). However, the specific mechanisms through which the NMDAR is involved in working memory versus plasticity differ. Towards gaining a deeper understanding of how NMDAR signaling relates to individual cognitive functions in healthy adults and patients with schizophrenia, the investigators used a single dose of d-cycloserine (DCS) as an experimental probe to examine the effects of enhancing NMDAR signaling on plasticity versus working memory in healthy adults and individuals with schizophrenia.

The purpose of this study is to gather information about the steady-state plasma concentrations of aripiprazole, olanzapine, quetiapine and their relevant metabolites, at various dose levels and at different time points after dosing. In addition, comparison of capillary drug concentrations vs. venous drug concentrations will be performed for aripiprazole, olanzapine, paliperidone, quetiapine, risperidone and their relevant metabolites.

The purpose of this study is to evaluate the use of the drug isradipine for cognitive enhancement in patients diagnosed with schizophrenia and schizoaffective disorder.

People with schizophrenia have two- to three-times the mortality risk of the general population. This is primarily due to their unusually high rates of cigarette smoking, as well as other cardiovascular risk factors such as physical inactivity, obesity, high blood cholesterol and diabetes. Effective smoking treatments are needed to reduce morbidity and mortality in this population. Over a dozen experimental studies indicate that walking and other forms of exercise acutely reduce cigarette craving, nicotine withdrawal symptoms and smoking behavior in non-psychiatric smokers. However, the effects of acute exercise on smoking measures have not been studied in smokers with schizophrenia. This study will use a within-subjects, repeated-measures design, in which participants will undergo 4 laboratory sessions (order counterbalanced across participants): (1) smoking cues followed by exercise, (2) smoking cues followed by passive activity, (3) neutral cues followed by exercise, (4) neutral cues followed by passive activity. Outcome measures include cigarette craving, nicotine withdrawal symptoms, mood and smoking behavior. If the results of this study indicate that walking acutely reduces craving and smoking in smokers with schizophrenia, the next step in this research would be to test the effectiveness of a smoking cessation intervention that incorporates exercise bouts as a behavioral strategy for improving smoking cessation rates in this population.

To evaluate the safety and tolerability of multiple, ascending doses of PF-04958242 administered orally to psychiatrically stable subjects with schizophrenia receiving antipsychotic and adjunctive medication.
