This is a multiple oral dose, open-label study to assess the safety, tolerability, and pharmacokinetics of SEP-363856 in Japanese subjects with schizophrenia.
This study investigates whether Introspective Accuracy (IA) can be improved in individuals with schizophrenia by stimulating the brain via transcranial Direct Current Stimulation (tDCS).
A recent double-blind placebo-controlled study has tested the effect of methotrexate as an add-on treatment for patients with schizophrenia or schizoaffective disorder, administering 10 mg of methotrexate or placebo once a week for a period of three months to 72 patients (Chaudry, Husain et al. 2015). Results showed improvement both in positive symptoms, as measured by the Positive symptoms subscale of the Positive and Negative Syndrome Scale (PANSS), and in total PANSS scores. The objective of this study is to replicate Chaudry et al.'s study. This proposed study will randomize schizophrenia or schizoaffective disorder patients to methotrexate or placebo for a period of four months. The study will enroll patients with a DSM-IV-TR diagnosis of schizophrenia or schizoaffective disorder confirmed by the Modified Structured Clinical Interview for Diagnosis (SCID). In order to be eligible to enter the study, the patient must have a score of 4 (moderately ill) or greater on the Clinical Global Impression - Severity (CGI-S) scale. In addition, inclusion criteria reflect patients with moderate or more severity on positive symptoms, hence having a score of 4 (moderate) or above on two of the following four PANSS items: delusions, hallucinatory behaviors, conceptual disorganization or suspiciousness/ persecution. Patients receiving more than one anti-psychotic or depot antipsychotic will be allowed to participate, and patients receiving anti-cholinergic agents, beta-blockers, anti-depressants, mood-stabilizers, sedatives, and anti-anxiety agents will be allowed in the study. Because the clinical status of patients sometimes improves in the days following admission to the hospital, newly hospitalized patients will have their baseline visit 3 days or more after being hospitalized.
The purpose of this research is to understand if it is helpful for patients with mental illness to be connected to a psychiatrist and case manager at the time of cancer diagnosis.
The purpose of this study is to determine whether luvadaxistat is superior to placebo in improving cerebellar function as measured with the average percentage of conditioned responses during the eyeblink conditioning (EBC) test.
The primary purpose is to evaluate the safety and tolerability of ASP6981 in participants with schizophrenia. Also primary purpose is to evaluate the pharmacodynamics of ASP6981 in participants with schizophrenia as measured by cognitive function and neurophysiological biomarkers. The secondary purpose of this study is to evaluate the pharmacokinetics of ASP6981 in participants with schizophrenia.
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.
The objective of the study is to investigate the efficacy, safety and tolerability of BI 409306 once daily compared with placebo given for 28 weeks in patients with schizophrenia on antipsychotic treatment. The study is designed to show superiority of BI 409306 over placebo in preventing relapse of schizophrenia symptoms.
All participants will receive free weekly counseling (8- weeks) and free nicotine patches (10-weeks). They will complete assessment measures commonly used in smoking cessation studies. We hope to show that this treatment is feasible in this small pilot study before comparing it to a more established treatment in a future randomized clinical trial.
