Active clinical trials for "Schizophrenia"

The purpose of this study is to explore the efficacy of paliperidone palmitate administered as a once monthly injection in patients with an acute exacerbation of schizophrenia.

This Phase I/IIa Proof-of-Concept (PoC) trial is designed to assess the effect of adding a single and repeated low dose (15mg/d) of pipamperone (PIP) for 6 weeks to stable treatment with an effective dose of risperidone (RIS) or paliperidone (PAL) on functional MRI tests and clinical outcome of chronic schizophrenic patients with residual, so-called 'positive' symptoms, as well as on cognition, motivation, subjective well-being of patients, negative symptoms, general psychopathological symptoms and safety/tolerability.

This study will determine the pharmacokinetics (PK), safety, and tolerability of ALKS 9072 (also known as ALKS 9070) after 4 monthly doses in adults with chronic stable schizophrenia.

Despite current antipsychotic treatment, the majority of people with schizophrenia continue to exhibit persistent positive and negative symptoms and cognitive impairments. An alternative approach to the use of psychotropic agents for the treatment of persistent symptoms is the use of anti-inflammatory agents to reverse the pro-inflammatory state hypothesized to underlie the symptom and sign manifestations of the illness. The investigators primary hypothesis is that add-on anti-inflammatory combination therapy will have significant beneficial effects on persistent positive symptoms and cognitive impairments. The investigators secondary hypotheses are: add-on anti-inflammatory combination therapy will be associated with improvements in depressive and negative symptoms and a reduction in pro-inflammatory cytokines add-on anti-inflammatory combination therapy compared to placebo will not be associated with elevated adverse risk.

Deficits in working memory (WM) performance are the most significant cognitive impairments in schizophrenia (SCZ). It has also been shown that WM performance is contingent on the cortex synchronization, a process that relies on brain inhibition. Repetitive Transcranial Magnetic Stimulation (rTMS) has been demonstrated as an effective treatment for patients with SCZ and has been shown to increase brain inhibition and improve cognitive performance. In this study the investigators intend to: evaluate rTMS as a treatment for WM deficits in SCZ evaluate rTMS as a method to increase WM performance in healthy individuals determine if improvements in WM performance are related to enhanced synchronization of brain networks determine whether genetic polymorphisms predict cortical function and treatment response evaluate the influence of rTMS treatment on brain structure.

The objective of this study is to evaluate the efficacy and safety of RP5063 relative to placebo for the treatment of schizophrenia or schizoaffective disorder.

The purpose of study is to determine whether dietary supplement sarcosine is effective in treatment of schizophrenia. The investigators will assess impact of sarcosine on quality of life and sexual functioning. In this project the investigators will also measure glycine, sarcosine, BDNF, MMP-9 levels and oxydative stress parameters in blood, brain glutamatergic metabolism parameters in magnetic resonance spectroscopy and oculomotoric changes in electrooculography.

The objective of this study is to evaluate the long-term safety, tolerability, and efficacy of MP-214 in patients with schizophrenia.

The rate of type-2 diabetes mellitus (T2DM) is at least 2-3 times higher in persons with psychotic illnesses than in the general population. Life expectancy of individuals with psychosis is also 20-25 years less than the general population, primarily due to premature onset of cardiovascular disease (CVD). Despite the high risk for T2DM and CVD, psychotic illness has been an exclusion criterion in all large-scale studies of diabetes prevention and management. We propose a 3-year randomized controlled trial examining the effectiveness of a lifestyle intervention (LI) aimed at reducing caloric intake and increasing physical activity in overweight or obese individuals (N=150) suffering from both a psychotic illness and T2DM. Weight and glycemic control will be the primary outcome variables. It is hypothesized that a significant weight reduction and improvement in glycemic control will be found in those who receive the LI relative to those who do not.

Schizophrenia is understood to be a heterogeneous brain condition with overlapping symptom dimensions. The negative symptom dimension, with its protean cognitive manifestations, responds poorly to treatment, which can be a particular challenge in countries where clozapine therapy is not available. Preliminary data indicates that minocycline may be beneficial adjunct in the treatment of schizophrenia: positive, negative, and cognitive symptoms. Persons with schizophrenia or schizoaffective disorder and recent onset schizophrenic episode or recent relapse who are prescribed minocycline in addition to standard antipsychotic medication will show greater symptom reduction, as measured by the Positive and Negative Syndrome Scale (PANSS) total score.
