Active clinical trials for "Schizophrenia"

An Extension study to a clinical study that will continue to evaluate the effectiveness and safety of SEP-363856 in people with schizophrenia that switch to SEP-363856 from their from their current antipsychotic medication. This study will accept both male and female participants that have completed study SEP361-308. This study will be held in approximately 24 study sites in North America. Participation in the study will be approximately up to 25 weeks.

The specific aim of this protocol is to compare Clozapine treatment vs Non-Clozapine antipsychotic treatment in a population of treatment-refractory individuals with schizophrenia. Specifically, it is to test if Clozapine leads to a decrease in levels of inflammatory markers, namely interleukin-6 but with an exploratory view of other markers. Clozapine has superior efficacy and is the only medication approved for treatment-refractory schizophrenia in addition to decreasing the risk of suicidal behavior as well. It is unclear why Clozapine has increased efficacy from a mechanistic viewpoint. We will look at the role of inflammatory markers and assess them 1x along with rating scales for psychosis and suicidality, the other entities which Clozapine has been shown to improve.

This pilot open-label study examines the effects of a combination of dasatinib plus quercetin - two drugs that have known senolytics properties - on physiological aging in older individuals with depression or schizophrenia.

This Study is a Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, Multi-Center, Fixed-Dose, Phase 3 Clinical Trial Evaluating the Efficacy and Safety of WID-RGC20 3 mg/day and 6 mg/day in Patients with Acute Psychotic Episode of Schizophrenia.

The goal of this observational study is to compare subjects with at-risk-mental-state, early psychosis, schizophrenia, depression, and autism spectrum disorders, with healthy controls (N = 21 x 6). The main questions it aims to answer are: are EEG microstate anomalies associated with diagnosis, clinical and functional prognosis, both in resting conditions and during sleep ? are EEG microstates anomalies associated with differences in sensorimotor integration, prosodic and conversational, interoceptive, and narrative self ? an ancillary study will be to see whether in healthy controls EEG microstate properties vary under light hypnosis conditions. Participants will: undergo deep phenotyping based on psychopathology and neuropsychological assessments undergo a high-resolution EEG (64 electrodes) with a resting period and a sensorimotor task; and healthy controls will have a light hypnosis period. undergo a recording of the characteristics of their voice (tone, prosody) undergo a one-night polysomnography undergo MRI and biological sampling for multi-omic analyses undergo a virtual reality experience

Severe mental illness such as schizophrenia and mood disorders typically develops at a young age and can cause life-long disability. Currently available treatments cannot cure severe mental illness. This makes it important to find ways to prevent severe mental illness in young people before it has a chance to develop. This research study will pilot a new preventive intervention for young people who are at high risk of developing severe mental illness. The investigators will target early preceding factors (the 'antecedents') to severe mental illness which includes anxiety, unusual hearing and visual experiences, the loss of previously acquired abilities, and sudden and unpredictable changes in mood. These antecedents strongly predict an increased risk of developing severe mental illness. They are often impairing and distressing to the individual but can be improved with self-management skills and parent training, and they are present in the individual years before the onset of severe mental illness which makes them an ideal target for early intervention. The goal is to intervene early enough in the young person's life that severe mental illness can be prevented, hopefully leading to a happy, healthy and productive adulthood. The investigators want to test the acceptability and short-term efficacy of this new preventive intervention.

The primary objective for this study is to evaluate whether Rituximab as compared to placebo is a clinically effective treatment for a subgroup of patients suffering from psychosis and/or obsessive-compulsive disorder (OCD) or -behavior (OCB) where there is an indication of immune system involvement. The secondary objectives of this study are To assess whether Rituximab treatment (with the doses and timing described below) as compared to placebo is associated with amelioration in psychiatric symptomatology To assess whether Rituximab treatment as compared to placebo is associated with improvement in executive functions To assess whether Rituximab treatment as compared to placebo is associated with amelioration in neurological symptoms To evaluate the longevity of psychiatric, neurological and executive improvements associated with Rituximab treatment for up to 16 months after the first infusion (i.e. 12 months after the last infusion) To evaluate whether Rituximab treatment as described is safe for these patients. The exploratory objectives of this study are To assess changes in blood and cerebrospinal fluid (CSF) markers for immune activity associated with Rituximab treatment compared to placebo To assess statistical associations between biological markers in blood or CSF and clinical response To describe changes in somatic symptoms associated with treatment with Rituximab vs placebo for patients with initial symptoms in the questionnaires To describe changes on MR and EEG associated with treatment with Rituximab vs placebo for patients with initial pathology in these examination To study immune mechanisms coupled with psychiatric symptoms, possibly identifying novel biomarkers with potential for subtyping encephalopathies with immune engagement, using biobank cells, blood and CSF samples collected from the participants.

This study is to determine the tolerability and efficacy of an accelerated schedule of Transcranial Magnetic Stimulation for treating symptoms of psychotic disorders such as schizophrenia.

Internalized stigma, (i.e. the application of negative stereotypes about a diagnostic group to one's self) is a strong predictor of recovery and quality of life for individuals with psychosis. Be Outspoken and Overcome Stigmatizing Thoughts (BOOST) is an evidence-based intervention aimed at improving internalized stigma, self-esteem, and quality of life for those with psychosis. The proposed research expands BOOST's program by adding additional therapeutic methods and material, and adopting the use of virtual care methods to: (a) increase the generalization of treatment effects, (b) examine long-term treatment effects, and (C) provide rural Ontario communities with remote treatment access.

It has been known that schizophrenia patients have a reduced ability to recognize both their own pain and the pain of others. The patients' pain judgement is not correlated with their affective or cognitive empathic capacities. These results suggest that changes in pain recognition in schizophrenia patients reflect specific dysfunctions in pain processing . Schizophrenia patients have a reduced ability to recognize both their own pain. This deficit is not related to their empathic capacities . The correlation between pain perception in schizophrenia patients and their ability to evaluate their own pain is still unknown. Pain insensitivity to pressure has been described in the context of schizophrenic illness was also evident in the biological relatives of those with the disorder. It is still unclear whether relatives of schizophrenia patients have aberrations in assessing their own pain in different imaginary situations. Animal models are important tools in the study of psychiatric disorders and the mechanism of action of antipsychotic and other psychiatric drugs. Positive symptoms of schizophrenia are difficult to model in rodents, but locomotor hyperactivity in response to a novel environment were reported as correlated with positive symptoms . On the other hand, negative symptoms such as social interaction and anhedonia and cognitive processing (e.g. emotional memory, sensorimotor gating, and associative learning) can be investigated in animal models with a high degree of validity . Furthermore, in most schizophrenia-like animal models, both first and second-generation antipsychotic drugs are reported to be effective in ameliorating behavioral abnormalities. It is well establish that patients with schizophrenia have been shown to display decreased sensitivity to pain, and antipsychotics are used to treat chronic pain. For example, chronic administration of phencyclidine or ketamine, psychomimetic drugs, produces decreased sensitivity to mechanical stimulation, and increased pain tolerance. The classic antipsychotic drug fluphenazine has anti-allodynic properties in multiple rodent models of nerve injury-induced neuropathic pain. An analgesic effect of quetiapine in the Cancer-induced bone pain animal model have been demonstrated. However, the mechanism of action to relive pain is still under debate and may differ between different agents. Animal models of acute and chronic pain allow evaluating the effects of analgesics drugs and other components on pain sensation and transmission, and underlining their molecular mechanism. Usually, these tests rely on an escape behavior or a withdrawal reflex as an index of pain. One known method of measuring responses to thermal stimuli involves application of a noxious thermal stimulus (hot or cold). This method has been used in order to investigate new analgesic components. Study hypothesis Schizophrenia patients and their biological relatives who have an aberrant sensation of pain also have a reduced capability to evaluate their own pain. Primary objectives Demonstrate that schizophrenia patients who suffer from pain insensitivity also have a reduced capability to evaluate their own pain, compared to population without a mental illness. Prove that the severity of pain insensitivity in schizophrenia patients is correlated to the degree of their ability to assess their own pain in different imaginary situations. Secondary objective Demonstrate that healthy biological relatives of schizophrenia patients have aberrations in assessing their own pain. Find the correlation between pain insensitivity in schizophrenia patients to pain insensitivity in their relatives. Find the correlation between the degrees in pain recognition in schizophrenia patients to pain recognition in their biological relatives. Investigate the impact of anti-psychotic drugs on pain threshold of schizophrenia patients. Study design This study is a prospective cross-sectional trial.
