Active clinical trials for "Schizophrenia"

Antipsychotic drugs are effective in treating the positive symptoms of schizophrenia; however their efficacy in treating negative symptoms is limited. This study wants to evaluate efficacy of selegiline augmentation of antipsychotic medication to treat negative symptoms in inpatients with chronic schizophrenia. With randomized clinical trial two groups of patients will select to receive selegiline or placebo. Primary end point is decreasing in negative symptoms in case group. Inclusion criteria : 1- Patients with moderate to severe negative symptoms 2- Patients with at least one year antipsychotic drug therapy, at the current dose >= 1 month. 3- No other psychotropic drugs during past month. Exclusion criteria: 1- Severe major depressive disorder, substance abuse, severe positive symptoms of schizophrenia, Treatment of MDD with antidepressant drugs during past month.

The purpose of this study is to estimate the proportion of participants fulfilling criteria for symptomatic remission following a transition to 12 months treatment with flexible-dose paliperidone palmitate 3 month formulation (PP3M) in participants with schizophrenia previously adequately treated with paliperidone palmitate 1 month formulation (PP1M) for at least 4 months.

The investigators hypothesis is that an antipsychotic drug combination of low-dose olanzapine plus low-dose trifluoperazine is similar to regular-dose olanzapine monotherapy in efficacy and safety for treatment of schizophrenia.The goal of this study is to compare the efficacy and safety of the olanzapine (10 mg/d) and olanzapine (5 mg/d) plus trifluoperazine (5 mg/d) in the treatment of acute psychotic exacerbations of schizophrenia.

The study medicine is a potential future treatment for schizophrenia, an illness that affects the way that people think, feel or behave. It is not clear what causes schizophrenia, but it's been linked to chemical imbalance in the brain. It is hoped that the study medicine will activate specific sites in the brain to help correct that imbalance. Current treatments for schizophrenia don't work very well and can cause unpleasant side effects. It is hoped that the study medicine will work better, and have fewer side effects than existing medicines. In this 2 part study (Parts A and B), the primary aim is to assess how safe the study medicine is in healthy men, aged 18-45 years, and how much of it gets into the blood. Its effects on the brain will also be tested. In Part A, up to 24 participants will receive up to 5 single doses of the study medicine (AUT00206 or placebo) by mouth, either after fasting or after a high fat breakfast. The study medicine has never been given to humans before, so the initial doses will be small and the dose level will be increased as the study progresses. Participants may take up to 14 weeks to finish the study. They'll make up to 22 outpatient visits, and stay on the ward up to 5 times, for 3 nights in a row each time. In Part B, 24 participants will receive daily doses of the study medicine (AUT00206 or placebo) for up to 28 days. Participants will take up to 10 weeks to finish the study. They'll make 6 outpatient visits, and stay on the ward for up to 30 nights, depending on how long we expect it to take until blood levels of the study medicine level off. A pharmaceutical company, Autifony Therapeutics Limited, is funding the study. The study will take place at 1 centre in London.

The specific aim of this proposal is to investigate the neurophysiological mechanisms of oxytocin's (OT) prosocial effects in patients with schizophrenia and healthy subjects using magnetoencephalography. Hypothesis A: When OT is administered to patients with schizophrenia, fear-related amygdala hyperreactivity and fusiform gyrus (FG) and anterior cingulate cortex (ACC) hypoactivity will be normalized. Hypothesis B: When OT is administered to patients with schizophrenia, the decreased functional connectivity (FC) between the amygdala, FG, and ACC will be normalized. By elucidating the neurophysiological mechanisms of OT administration on emotional face processing, investigators will bee able to: understand the pathophysiology of the functionally debilitating social cognitive deficits of schizophrenia, test the efficacy of OT in normalizing the neural abnormalities underlying these social deficits, and develop and optimize novel treatments for these currently untreatable deficits.

The primary purpose of this study is to evaluate the efficacy of lurasidone 20 mg/day in subjects with an acute exacerbation of schizophrenia.

This is an extension of a previous study (ALK9072-003EXT). The purpose of this study is to continue to evaluate the long-term safety and durability of effect of ALKS 9072 in subjects with stable schizophrenia, and to allow subjects who are doing well on ALKS 9072 to continue treatment.

The purpose of this study is to characterize the safety and tolerability of TAK-063 when administered as multiple oral doses at escalating dose levels in participants with stable schizophrenia and in healthy Japanese participants.

The aim of the study is to examine whether determining treatment strategies based upon Cytochrome P450 2D6 (CYP2D6) genotype will improve drug response rates and clinical outcome in patients with psychosis. The investigators predict that prospectively testing CYP2D6 genotype and using this information to treat psychotic patients with risperidone will improve clinical outcomes. Specifically, CYP2D6 poor metabolizers who are treated with low dose and slow titration of risperidone will do better than those who are treated with usual dose and titration approach in terms of rates of side effects and clinical improvement.

Current evidence suggests that schizophrenia as a serious and complex psychiatric disorder, continues to challenge mental health professionals in their search for better treatment options in the community. In the present study, the investigators hypothesized that in patients diagnosed as schizophrenia, adjunct treatment with Curry extract from the plant labeled by botanists as Curcuma Longata, formulated as Super-Curcumin@ , would bring about :1)positive behavioral changes in areas of socialization, emotional well-being, verbal communication and motivation; 2)improvement in measures of memory. Throughout the study, the proprietary product, Super-Curcumin@ consisting of Curcumin C-3 complex combined with the black pepper extract Bioperine to boost the effects of Curcumin. The study was developed to examine whether Curcumin's interaction with the two major signal pathways in the brain regulating brain-behavior: the epigenetic signal (histone modification) and the anti-inflammatory signal (inducible nitric oxide synthetase)in preclinical models is translated to beneficial effects in the treatment of schizophrenia.
