Active clinical trials for "Schizophrenia"

The purpose of the study is to test a new treatment of social cognition deficits in patients with schizophrenia or schizoaffective disorder by transcranial magnetic stimulation (theta-burst). The study will also identify clinical, psychomotor and cognitive variables that are the most sensitive to treatment, and estimate the most sensitive treatment target between patients.

The purpose of this study is to evaluate the effectiveness of a visual remediation intervention for people with schizophrenia. The intervention targets two visual functions that much research has shown are impaired in many people with the disorder, namely contrast sensitivity and perceptual organization. The first phase of the study will test the effects of interventions targeting each of these processes, as well as the effects of a combined package. A control condition of higher-level cognitive remediation is included as a fourth condition. The second phase of the study will evaluate the effectiveness of the most effective intervention from the first phase, but in a new and larger sample of individuals. Outcome measures include multiple aspects of visual functioning, as well as visual cognition and overall community functioning.

This randomized, sham-controlled, double blind, multicentre clinical trial aims at providing evidence for the efficacy and safety of continuous theta burst stimulation (cTBS) in the treatment of auditory hallucinations in patients with schizophrenia. Overall, the study will include 137 patients. Because of the adaptive study design, an interim analysis was performed after half of the originally planned patients (43/86), according to which the sample size was increased by 51 patients). Each patient will receive a three weeks course of daily (5/week) treatment; 50% of the patients will be treated with cTBS (1200 impulses daily), the other half with a sham stimulation to the left and right temporoparietal cortex. Sham stimulation will be applied by an active sham-coil that allows for a double-blind treatment. Follow-up assessments 1, 3 and 6 months after treatment will investigate the stability of treatment effects.

This study is a Phase 1 clinical trial to determine the safety, tolerability, and efficacy of Siltuximab (Sylvant) as an adjunct to antipsychotic medications in stable outpatients with schizophrenia. Siltuximab (structural formula C6450H9932N1688O2016S50) is a recombinant chimeric (human-murine) anti-human interleukin-6 (IL-6) monoclonal antibody. Siltuximab is formulated as a concentrate for solution for infusion, and will be administered by intravenous infusion. The investigators propose a 9-week randomized controlled trial of siltuximab, given in adjunct to antipsychotics, in N=30 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 siltuximab will be associated with significant improvement in cognition compared to placebo in patients with schizophrenia, baseline IL-6 levels are higher in siltuximab-treated responders versus non-responders, and there will be greater decreases in hsCRP from baseline to week 6 in siltuximab-treated versus placebo-treated responders, with response defined as ≥0.5 SD improvement in cognition. Siltuximab is administered as an intravenous infusion every 3 weeks. Following a screening evaluation, participants will receive three infusions of siltuximab, one at baseline, another at week 3 of the study, and another at week 6. The investigators will measure changes in cognitive function and symptoms over a 9-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. Janssen Pharmaceuticals, Inc. began the clinical development of siltuximab for the treatment of multicentric Castleman's disease, a rare blood disorder. Other clinical studies with siltuximab have been conduced for patients with B-cell non-Hodgkin's lymphoma, multiple myeloma, and ovarian cancer. In April 2014,siltuxiumab was approved by the U.S. Food and Drug Administration (US FDA) as Sylvant for human immunodeficiency virus (HIV)-negative and human herpesvirus-8 (HHV-8)-negative multicentric Castleman's disease.

The study examine the effectiveness of an integrated care program including therapeutic assertive community treatment (ACT) for people with psychotic disorders fulfilling severe and persistent mental illness (SPMI, ACCESS-II study).

The purpose of this study is to determine if NaBen® is a safe and effective add-on treatment for schizophrenia in adolescents.

Schizophrenia is a mental health issue that affects mostly young adults. The main symptoms are hallucinations, delirium, and agitation, poor social relations, lack of motivation, thought disorganization. Also, patients suffering from schizophrenia encounter important cognitive disorders affecting memory, executive functioning and attention. These cognitive alterations are often linked to social exclusion and stigmatisation. Antipsychotic treatments are effective mainly on the positive dimension of symptoms (hallucinations etc…); however their action is very limited on the cognitive difficulties encountered. Psychosocial techniques can be used to treat the cognitive symptoms, such as cognitive remediation or psychosocial rehabilitation . These cognitive difficulties mainly have an impact on patients' daily life, affecting their abilities to drive, for example. Schizophrenic patients suffer more road accidents than healthy subjects . Thus, considering this information, it appears important to us to address this driving problem for various reasons: Firstly, knowing how to drive is often linked to daily autonomy, Secondly, driving is also linked to keeping an active social network and to work. Patients suffering from schizophrenia often encounter difficulties in learning how to drive which reinforces the stigmatisation and fear of failure. Thus, a specific driving and theory training prior to driving lessons could be a way of helping patients in their cognitive difficulties and pass their driving test. Daily transports mobilize a number of cognitive functions (attentional vigilance, working memory, psychomotor coordination, divided attention, visuo-spatial abilities . Using a driving virtual reality tool could constitute an ecological cognitive remediation tool, by simulating daily driving situations. This "serious game" approach enables us to involve virtual reality in training but also in assessments. The driving simulator allows standardized evaluations and could also become a therapeutic tool of ecological cognitive remediation. This study thus appears interesting in order to develop road safety and daily autonomy.

The majority of schizophrenia patients is impaired in hand gesture performance, which contributes to poor functional outcome and poor communication skills. The left inferior frontal gyrus (IFG) and the left inferior parietal lobe (IPL) are key nodes of the gesture network, which is less active in patients with schizophrenia. Here, the investigators test single 10 min sessions of tDCS known to either enhance or inhibit local brain activity for app. 1 hour. The investigators aim to determine, which protocol may improve gesture performance in patients and healthy controls. This is a randomized, double-blind, cross-over, placebo-controlled single-center trial in 20 patients with schizophrenia spectrum disorders and 20 healthy controls. Gesture performance will be tested immediately after each tDCS session, which are separated by 24 hours. Results of this study will inform larger interventional trials comparing 2 tDCS protocols with repeated administration.

Cognitive impairment, the core psychopathology of schizophrenia, usually persists in schizophrenia patients even during symptomatic remission. While cognitive impairment associated with schizophrenia (CIAS) is an important therapeutic target, hypofunction of N-methyl-D-aspartate receptor (NMDAR) is a key factor of CIAS. This study aims to examine the efficacy and safety of an NMDA-enhancer (NMDAE) for the treatment of CIAS in schizophrenia patients during symptomatic remission.

This pilot feasibility trial aims to evaluate the "Goals in Focus" intervention for motivational negative symptoms in people with psychosis. Goals in Focus interventions translate findings of basic clinical research on psychological mechanisms of motivational negative symptoms into a tailored and comprehensive novel psychological treatment program. The current single-blind randomized-controlled study aims to test feasibility and to examine first estimates of the expected effect size of Goals in Focus to inform a subsequent fully-powered RCT. The feasibility data will be used to improve on the trial design and the provision of the "Goals in Focus" intervention where necessary.
