Active clinical trials for "Schizophrenia"

The investigators will test the hypothesis that auditory stimulation (playing quiet sounds during sleep) can normalize brain activity during sleep and improve memory in patients with schizophrenia. The investigators will do this by measuring sleep and memory performance under two conditions separated by one week: receiving auditory stimulation during sleep and not receiving auditory stimulation during sleep. The investigators will study healthy subjects and outpatients with schizophrenia.

The INTRUDE trial aims at assessing the efficacy of an fMRI-based neurofeedback procedure on drug-resistant auditory hallucinations. Hallucinations are complex and transient mental states associated with subtle and brain-wide patterns of activity for which we were recently able to validate an fMRI multivariate decoder. Based on this progress, we can track patients' hallucinatory status using real-time fMRI. We will test whether schizophrenia patients with drug-resistant hallucinations can be trained to maintain the brain state associated with a no-hallucination condition using appropriate strategies and thus reduce overall severity. We will refer to a double-blind randomized placebo-controlled design. A total of 86 patients will be enrolled and equally split in an active neurofeedback group (n=43) and a sham group (n=43), matched for sex, age and PANSS scores. Each patient will benefit from 4 runs of either active or sham neurofeedback. The primary outcome measure will be the mean decrease of AHRS scores relative to baseline, and at 1 month post-treatment. We expect significant clinical benefits from fMRI-based neurofeedback on drug-resistant hallucinations compared with the sham group.

This is a Phase Ib clinical study of TPN672 maleate in patients with schizophrenia

The study use a new ecological questionnaire called ESSME developed by a care team in order to evaluate ecological environment of patients with schizophrenia-like disorders. Indeed, evaluation in an ecological environment would make it possible to be as close as possible to the concerns of theses patients, which could improve the care of this population, by making it possible to set with the patient objectives anchored in their daily life.

Clinical trial to assess the efficacy of Vortioxetine compared with treatment as usual in early schizophrenia.

Schizophrenia, bipolar and major depressive disorders collectively affect over 10 million people across the EU and are associated with annual healthcare and societal costs in excess of 100 billion Euros. When diagnosed with one of these disorders, patients are prescribed psychotropic medication such as antidepressants, mood stabilisers or antipsychotics. It is unknown whether this first-line treatment will be successful. After this first-line treatment fails, usually a second-line treatment is initiated, and when this is not successful either a third-line treatment is initiated. Third-line treatments are quite successful, especially when compared to second-line treatments. The research question is whether the third-line treatments (early-intensified treatments) would be more efficacious than the current second-line treatments (treatment as usual) for schizophrenia, bipolar and major depressive disorders. If this is indeed the case, this could lead to the prevention of unnecessary trials of ineffective treatments and adaptations of worldwide guidelines as well as a reduction of healthcare and societal costs.

The purpose of this study is to examine state representation in individuals aged 15-40 who have been diagnosed with a psychotic illness, as well as young adults who do not have a psychiatric diagnosis. State Representation is our ability to process information about our surroundings. The investigators will complete some observational tests as well as a cognitive training clinical trial.

Olanzapine is a thieno-benzodiazepine derivate that is effective managing the symptoms of schizophrenia and reducing the psychopathological symptoms of psychosis. It is also effective in controlling the acute manic episodes associated with bipolar disorder, and have provided some therapeutic advantages over other antipsychotic agents (Citrome et al., 2019). However, Ola administration has been reported to induce profound BWG accompanied with higher incidence of metabolic deficits, such as hypertension, diabetes and hyperlipidemia, as compared to other antipsychotic agents (Mauri et al., 2014). Adjunctive treatment with other agents that can minimize or normalize Ola-induced BWG can enhance the safety and tolerability profiles of an effective antipsychotic, thus highlighting the need to develop improved therapies or interventions to minimize these side effects. A meta-analysis of 12 published studies found that antidiabetic drugs such as metformin improved metabolic parameters in patients treated with antipsychotics (de Silva et al., 2016). These studies encouraged the evaluation of other antidiabetic agents as adjunctive therapies to minimize Ola-induced BWG. Empagliflozin (EMPA)is the third-generation anti-diabetic drug acting as sodium-glucose transport protein two inhibitor (SGLT2), which provides a new mechanism of action to improve glycemic control with modest decreases in systolic blood pressure and body weight (Pradhan et al., 2019). The effects of EMPA on Ola-induced BWG have not been determined and require further investigation.

Establishment of a patient library for patients who have had a first psychotic episode and who have an "at risk" status for psychotic disorder (GRD, APS, BLIPS group) or a psychosis threshold during CAARMS administration. Samples are taken on inclusion, at 2 years, and if relapse or significant clinical event within 5 years of inclusion, on 250 patients for 10 years.

Childhood trauma is known as a vulnerability factor in schizophrenia. In healthy volunteers, these adversities are linked to a decrease of grey matter of the brain, similar to those observed in schizophrenia. In a previous study based on Voxel-Based Morphometry (VBM), including 21 schizophrenic patients and 30 healthy volunteers, the investigators shown a negative correlation between emotional neglect (important dimension in childhood trauma) and grey matter decrease. This strong correlation was significantly higher in schizophrenic patients than in healthy volunteers, suggesting a higher genetic predisposition to environmental factors in schizophrenic people. Currently, interaction between genetic predisposition and environmental stress factors is the major model for understanding in schizophrenia. In order to analyze both effects on human body, particularly on brain, several studies currently focus on the product of genetic expression, the ribonucleic acid (ARN). The purpose of this study is to provide an explanatory model of links between childhood trauma, candidate gene for schizophrenia expression, cerebral morphology and schizophrenic symptomatology. Using conceptual framework of stress vulnerability, structural equation modeling (SEM) will allow testing causal link between these different variables.
