Active clinical trials for "Psychotic Disorders"

Psychotic disorders typically emerge during late adolescence or early adulthood. Patients, who are diagnosed with a psychotic disorder before turning 18 years, are defined as early onset psychosis patients (EOP). Relative to adult patients, these patients show a worse long-term prognoses. Social impairment present a major barrier towards recovery, and thus and important issue to address in treatment. Cognitive behavioral therapy (CBT) is the recommended psychological treatment for psychotic disorders. As part of the therapy, the patient does an exposure-based training in a social environment. This type of training has several limitations for patients with psychosis. The last decade there has been a growing interest in using virtual reality (VR) to understand and treat various psychological disorders. There is a lack of research on VR-interventions for EOP patients. This study will assess the acceptability, tolerability, feasibility and clinical efficacy of a novel VR-assisted CBT interventions for adolescents with psychosis.

To this day, a small number of studies have evaluated the effect of melatonin on the modifications of the characteristics of sleep in critical care units, with mostly a small studied population. However, no study has been realized on a large population, nor has it evaluated the association between genetic factors and response to treatment (melatonin), hence the originality of our study. In our study we hypothesized that systematic melatonin usage in ICU can ameliorate the total sleep time and the fragmentation index and can decrease the confusion related to sleep deprivation.

Disturbances in glucose metabolism and glutamate neurotransmission feature in the pathophysiology of psychotic disorders. Ketogenic diet (KD) is a high-fat, low-carbohydrate diet that restricts glucose and forces metabolism of ketones, which serve as alternative energy substrates for the brain. KD is an established treatment for intractable epilepsy. However, we lack the randomized controlled trials (RCT) evidence regarding potential effects of KD on psychotic symptoms in humans. This randomised, controlled pilot study aims to investigate: feasibility of a Modified Ketogenic Diet (MKD) intervention protocol in psychotic inpatients, potential impact of MKD intervention on psychotic symptoms, depressive and anxiety symptoms, and functioning in patients with psychotic symptoms / psychotic disorder. A 6-week randomised KD pilot study will be carried out in psychotic inpatients (aimed n=40) at Kuopio University Hospital, Finland. In the KD group, carbohydrate consumption is limited to 15-20 g/day to activate ketosis. The control group will have their ordinary hospital meals. A number of different assessment will be carried out at time points 0, 1 week, 3 weeks and 6 weeks.

This study is a Phase 1 clinical trial to determine the safety, tolerability, and efficacy of Tocilizumab (Actemra) as an adjunct to antipsychotic medications in stable outpatients with schizophrenia. Tocilizumab (structural formula C6428H9976N1720O2018S42) is a recombinant humanized anti-human interleukin-6 (IL-6) receptor monoclonal antibody of the immunoglobulin G1 (IgG1) subclass. Tocilizumab is formulated as a concentrate for solution for infusion, and will be administered by intravenous infusion. The investigators propose a 12-week randomized controlled trial of tocilizumab, given in adjunct to antipsychotics, in N=20 stable outpatients with schizophrenia or schizoaffective disorder and evidence of increased inflammation in the peripheral blood (high-sensitivity C-reactive protein [hsCRP]>0.5 mg/dL). The investigators hypothesize that adjunctive treatment with tocilizumab will be associated with significant improvement in cognition compared to placebo in patients with schizophrenia, and baseline IL-6 levels are higher in tocilizumab-treated responders versus non-responders, and there will be greater decreases in hsCRP from baseline to week 12 in tocilizumab-versus placebo-treated responders, with response defined as ≥0.5 standard deviation (SD) improvement in cognition. Tocilizumab is administered as an intravenous infusion every 4 weeks. Following a screening evaluation, participants will receive three infusions of siltuximab, one at baseline, another at week 4 of the study, and another at week 8. The investigators will measure changes in cognitive function and symptoms over a 12-week period. Complementing previous positive clinical trials of non-steroidal anti-inflammatory drugs, this would be a "proof-of-concept" study that targeting specific cytokines is a viable treatment for schizophrenia. Interleukin 6 and its receptor were discovered and cloned at Osaka University, Japan, by Tadamitsu Kishimoto in the 1980s. In 1997, Chugai Pharmaceuticals began the clinical development of tocilizumab for the treatment of rheumatoid arthritis. Clinical studies for Castleman's disease and systemic juvenile idiopathic arthritis started in 2001 and 2002, respectively. Hoffmann-La Roche co-developed the drug due to a license agreement in 2003. On 11 January 2010, Tocilizumab was approved by the U.S. Food and Drug Administration (US FDA) as Actemra for the treatment of rheumatoid arthritis. The FDA approved tocilizumab for the treatment of systemic juvenile idiopathic arthritis for children from two years of age in April 2011.

Patients with Parkinson's disease (PD) sometimes experience symptoms affecting their movement, such as slowness, tremor, stiffness, and balance or walking problems. Many patients also have other symptoms not related to movement, called non-motor symptoms, which may affect one's mood or emotions, memory or thinking, or cause one to see or hear things that aren't real (hallucinations) or believe things that aren't true (delusions). Hallucinations or delusions, together called psychosis, occur in up to 60% of PD patients at some point in time. Parkinson's disease psychosis can sometimes be associated with decreased quality of life, increased nursing home placement, increased rate of death, and greater caregiver burden. There are approximately 50,000 Veterans with Parkinson's disease receiving care in the VA, and up to 30,000 (60%) of them will experience psychosis at some point in time. Quetiapine is an antipsychotic drug approved by the Food and Drug Administration (FDA) that is the most commonly used medication to treat PD psychosis, but more studies are needed to determine if it works for this condition and is also well tolerated and safe. Pimavanserin is a newer antipsychotic drug approved by the Food and Drug Administration (FDA) specifically to treat PD psychosis, but more studies are needed to determine if it works and its safety. The purpose of this research is to gather additional information on the safety and effectiveness of both Quetiapine and Pimavanserin. By doing this study, the investigators hope to learn which of these medications is the most effective course of treatment for people with PD psychosis.

The study is a randomised, assessor-blinded parallel-groups superiority clinical trial fulfilling the CONSORT criteria for non-pharmacological treatment. A total of 256 patients will be allocated to either Cognitive Behavioural Virtual Reality Therapy plus treatment as usual, versus traditional CBT for psychosis plus treatment as usual. All participants will be assessed at baseline and 3- and 9 months post baseline. A stratified block-randomisation with concealed randomisation sequence will be conducted. Independent assessors blinded to the treatment will evaluate outcome. Analysis of outcome will be carried out with the intention to treat principles.

Antipsychotics affects the brain's dopamine system, and the drugs reduce delusions, hallucinations, and disorganized thinking, which are cardinal symptoms of psychotic disorders. However, negative symptoms e.g. anhedonia, avolition, and social withdrawal, as well as cognitive deficits, are not sufficiently treated. Memantine is used to treat Alzheimer's disease and affects the brain's glutamate system. AMEND is a 12-week, double-blind, placebo-controlled, randomized clinical trial (RCT) testing effects of add-on memantine to initial antipsychotic treatment in never-treated patients with first-episode psychosis. The main aim is to reduce negative symptoms. Secondary outcomes are cognition, psychotic symptoms, side effects. Glutamate levels in the brain will be measured before and after 12 weeks using an ultra-high field strength (7 Tesla) magnetic resonance scanner. AMEND will apply rational drug repurposing to optimize treatment of patients experiencing their first psychotic episode.

Schizophrenia and depression are among the most disabling disorders in all of medicine. Cognitive deficits play a key role in patients' disability, affecting their capacity to contribute actively to society by sustaining employment or academic activity. Moreover, cognitive difficulties tend to persist even after the stabilization of other clinical symptoms. Verbal memory and emotion regulation are two important cognitive domains that are impaired in schizophrenia and depression and are associated with patients' functional outcomes. However, no medication has shown clear positive effects on these impairments at this point. Therefore, there is a great need to find effective cognitive remediation treatments (CRT) that could improve these domains in both psychiatric populations. In this study, the investigators will assess the efficacy of a cognitive rehabilitation intervention on the targetted cognitive domains (i.e., verbal memory and emotion regulation), general cognition, brain functioning, community functioning, symptom severity, and perceived cognitive deficits in both psychiatric populations. The study team also aims to investigate potential predictors of positive response to the intervention.

Adults with psychiatric disabilities get sick and die 20 to 30 years younger than same-age peers, with even greater disparities occurring when the person is from a low SES or of color. Factors explaining this difference are complex and include genetic comorbidity, iatrogenic effects of medication, life choices, and life consequences. These factors are worsened by service disparities which are often fragmented in the public health system. Peer navigators are part of a program in which providers escort people with psychiatric disabilities around the fragmented system to meet their health and wellness goals, often a demanding task for the person who has needs addressed at clinics, labs, and pharmacies spread across an urban area. Navigators are peers because they have lived experience of recovery and are often from similar ethnic groups. A community-based participatory research program supported by NIMHD and PCORI developed a peer navigator program specific to the needs of people with psychiatric disabilities. Results of two small pilots funded by NIMHD and PCORI showed the Peer Navigator Program (PNP) led to significant improved service engagement which corresponded with better health, recovery, and quality of life. The studies included fidelity measurement which showed peer navigators conducting the intervention at high levels of fidelity. The current research is an efficacy study with a more fully powered test of PNP versus treatment as usual, which is integrated care (TAU-IC). The investigators aim to recruit 300 adults with psychiatric disability who wish to improve physical health/wellness through peer health navigation randomized to TAU-IC or TAU-IC plus PNP. Individuals will participate in assigned interventions as part of 8-month cohorts with data being obtained at baseline, 4, 8, and 12 months. Data will include personal descriptors (demographics, diagnosis, life consequences report), outcomes (service engagement, physical symptoms, blood pressure, recovery, and quality of life), mediators (personal empowerment, self-determination, and perceived relationship for recovery), and process measures (fidelity, feasibility, and acceptability). Investigators hypothesize that those in PNP intervention will have improved outcomes over the integrated care as usual. A cost-benefit analysis will seek to model impact based on quality-adjusted life years. Larger effect sizes will permit post hoc identification of how PNP effects vary by participant characteristics such as ethnicity and gender.

This is an in-clinic, single arm, open-label study assessing tachyphylaxis, tolerance, and withdrawal following repeated doses of Igalmi in adult males and females with agitation associated with schizophrenia or bipolar disorder.
