NCT03788759
Schizophrenia is a devastating mental disorder with a prevalence of approximately 1% worldwide. While effective in reducing positive symptoms, current treatments have limited effects on cognitive and social cognition/processing deficits of schizophrenia, which are closely linked to real-world dysfunction and lack of socio-occupational integration. There is compelling evidence for impaired antioxidant defense system and inflammatory abnormalities in schizophrenia. A new therapeutic approach to the disease might well be to hinder oxidative damage, inflammation and its clinical sequelae. Alpha-lipoic acid (ALA) is a naturally occurring compound, synthesized in the mitochondria, that is currently approved to treat diabetic neuropathic pain. Drug repurposing is a fast, and cost-effective method that can overcome drug discovery challenges of targeting neuropsychiatric disorders. In a pilot investigation, adjunctive treatment with ALA led to robust improvement in negative and cognitive symptoms of ten patients with schizophrenia. This project aims to investigate the efficacy of ALA as a disease-modifying drug for the treatment of schizophrenia, by improving sociability and cognition, as well as to correlate patients' response with biomarkers that will shed light on the pathophysiology of this complex disease. It comprises 1) a prospective, randomized, double-blind, placebo-controlled trial to evaluate efficacy of ALA to treat cognitive and negative symptoms of patients with schizophrenia and 2) an investigation of changes in biomarkers of oxidative stress in response to adjunctive treatment with ALA. The proposed study could establish a new adjunctive treatment for schizophrenia, recognize a novel pharmacological approach and help unveil the biological basis of the disease.
NCT05498571
Schizophrenia is a serious mental illness that has a great impact on social function. Studies have evidenced that schizophrenia patients live 10-20 years less than general population.It mainly dues to high cardiovascular risk. How to improve patients' survival rates? At present, there is an objective model to assess cardiovascular risk among schizoprenia patients in England - PRIMROSE.But there is a lack of model for schizophrenia patients in china. In order to better guide clinical practice, we are now exploring a domestic cardiovascular risk prediction model to raise people's awareness.
NCT03872310
The investigators plan to investigate the effect of enhancement on working memory (WM) in patients of chronic schizophrenia and determine the predictive factors of effective treatment.
NCT02739347
This study proposes to assess the effect of trans-cranial direct current stimulation (tDCS) on cognitive control, working memory, functional, clinical, and cognitive outcomes in schizophrenia patients.
NCT03007628
This trial attempts to evaluate the treatment efficacy of magnetic seizure therapy (MST) and its safety among schizophrenia patients. Half of the participants will be randomized to MST group, while the other half will be randomized to receive electroconvulsive therapy (ECT).
NCT00716755
Since side effects of antipsychotics, dopamine D2 receptor blockers, frequently occur in older patients with schizophrenia and the risk is dose dependent, clinical guidelines universally advocate the use of lower doses. However, there is no report to test this dosing guideline with measurements of D2 receptor blockade caused by antipsychotics. In this study, dopamine D2 receptor occupancy will be measured, using Positron Emission Tomography (PET), in 40 patients aged 50 and older with schizophrenia-spectrum disorders before and after a gradual 40 % dose reduction of antipsychotics that was safely achieved in the past study while setting a target dose still above the lower limit of the dose range recommended in clinical guidelines for older patients. Our goal is to relate changes in clinical outcome, including subjective and objective clinical ratings, to dopamine D2 receptor occupancy, and compare these results with the data for younger patients in the literature.
NCT05140135
This study is evaluating the effectiveness of recovery oriented cognitive therapy (CT-R) for patients with schizophrenia/schizoaffective disorder. To evaluate CT-R, the investigators are conducting a randomized controlled trial with patients from community mental health centers. Participants will be randomized to the CT-R condition, in which the participants will receive approximately 9 months of CT-R as an adjunctive treatment to current medical treatment, or to the continued usual care control condition. The primary outcome measure (positive, negative, and general psychopathology symptoms) as well as secondary measures (quality of life, self-esteem, social anhedonia, recovery, dysfunctional attitudes, resilience, internalized stigma, and hopelessness) will be measured at baseline, 4-5 months after the first therapy appointment, approximately 9 months after the first therapy appointment, and approximately 15 months after the baseline appointment.
NCT04268797
Primary objective: to examine the efficacy and safety of high frequency repetitive transcranial magnetic stimulation (HF rTMS) with H7-coil applied once daily during the twenty days, augmentative to the standard antipsychotic pharmacotherapy and other treatment of negative symptoms in schizophrenia. Targeted population: patients diagnosed with schizophrenia, 18-55 years old with predominant negative symptoms, stable condition for \>3 months and unchanged antipsychotic therapy for \>1 months and no treatment with antidepressants. Study design: industry independent, multicenter, prospective randomized sham-controlled, two-arms, triple-blind superiority clinical trial with concealed allocation and masked independent outcome assessment. Primary outcome: adjusted median of differences in total SANS score. Adjustment for age, gender, baseline total SANS score, duration of the disorder, and antipsychotic therapy.
NCT03149107
Schizophrenia is a severe mental disorder associated with significant impairments in affective, cognitive and social functioning. Consequently, a special interest in the prevention of schizophrenia and psychotic disorders has emerged. Pharmacological as well as psychological interventions show promising preventive effects. The purpose of this multicentric study is the investigation of possible preventive effects of a treatment combination containing a psychotherapy form and medication (N-Acetylcytein - NAC) in individuals with an enhanced risk for developing schizophrenia. Both treatment forms may reduce the risk in this population due to their specific properties: The psychotherapy can improve social skills, whereas NAC is supposed to develop its protective effects on neuronal level due to its antiinflammatory properties. The investigators will examine the preventive effects by measuring transition rates to psychosis after treatment as well as improvements in social, affective and cognitive functioning.
NCT04588129
This is an open label study in 4 cohort of 4 healthy volunteers each designed to evaluate the dopamine receptor occupancy of LB-102 at various doses and timepoints.
NCT04618250
People with a severe mental illness (SMI) have an increased risk for premature mortality, predominantly due somatic health conditions. Evidence indicates that prevention and improved treatment of somatic conditions in patients with SMI could reduce this excess mortality. This paper reports a protocol designed to evaluate the feasibility and acceptability of a coordinated co-produced care programme (SOFIA model) in the general practice setting to reduce mortality and improve quality of life in patients with severe mental illness. The primary outcomes are description of study feasibility (recruitment and retention) and acceptability. The SOFIA trial is designed as cluster randomized controlled trial targeting general practices in two regions in Denmark. 12 practices will each recruit 15 community-dwelling patients aged 18 and older with severe mental illness (SMI). Practices will be randomized in a ratio 2:1 to deliver a coordinated care program or care-as-usual during a 6 month period. An online randomized algorithm is used to perform randomization. The coordinated care program comprises enhanced educational training of general practitioners and their clinical staff, and prolonged consultations focusing on individual needs and preferences of the patient with SMI. Assessments are administered at baseline, and at end of study period. If delivery of the intervention in the general practice setting proves feasible, a future definitive trial to determine the effectiveness of the intervention in reducing mortality and improving quality of life in patients with SMI can take place.
