Active clinical trials for "Schizophrenia"

Luteolin is a natural product found in foods such as celery, green pepper, parsley, and chamomile tea. It has been found to have anti-cancer, anti-oxidant, and anti-inflammatory properties. The purpose of this study is to determine if luteolin helps improve symptoms of schizophrenia.

Background: Impairment in cognitive processing speed is a consistent finding in schizophrenia spectrum disorder. Vitamin D deficiency is found to be significantly associated with reduced processing speed. In this study, we will investigate the effect from vitamin D supplementation on processing speed. Objective: The primary objective is to investigate whether vitamin D supplementation is superior to placebo in improving processing speed. The secondary objectives are to investigate whether vitamin D supplementation is superior to placebo in improving negative symptoms, social and physical activity. Study design: Randomized placebo-controlled double blind trial. Study population: Men and women, aged 18-65 years, diagnosed with a schizophrenia spectrum disorder, in treatment for their disorder at the Division for Mental Health at Akershus university hospital. Intervention: Participants will be randomized 1:1 to either vitamin D3 (50µg capsules) or placebo daily for 12 weeks. The medical product or placebo will be given in addition to treatment as usual. Study measures: Cognitive tests, symptom assessments and blood sampling for vitamin D analyses will be performed at baseline and after 12 weeks intervention. During the 12 week intervention period the participants will use a smart phone application (MinDag) for self-report and an actigraph (MotionWatch 8 actigraph from CamNtech) for registration of physical activity. Endpoints: Primary outcome is change in cognitive performance on the symbol coding test from the Brief assessment of Cognition in Schizophrenia (BACS). Secondary outcomes are change in performance on the the Category Fluency Test from the MATRICS Consensus Cognitive battery, change in negative symptoms from the clinician rated Brief negative symptom scale (BNSS), and change in self-reported negative symptoms from the scale Self-assessment of negative Negative Symptoms (SNS). Secondary outcomes also include change in self-reported social activities and change in actigraph registered physical activity. Expected benefits for consumers and caregivers: The results from the study will indicate whether vitamin D supplementation could represent a beneficial treatment strategy for impaired processing speed and related symptoms.

This is a hybrid1, effectiveness-implementation study of yoga-based exercises (YE) as an adjunctive tool for rehabilitation among persons with Severe Mental Illness (SMI). The two-arm randomized controlled trial will compare the efficacy of YE compared to the Wellness Lifestyle Program (WLP). Primary outcomes of the study will be self-report and performance-based measures of community functioning, defined in the investigators study as social, leisure, employment, and life skills functioning in the community. Secondary outcomes will include cognition and physical fitness measures.

This study is a prospective, multicenter, controlled, real world study. Patients will be randomly enrolled into the test group and the control group at a ratio of 1:1 during the screening period. The test group will choose to add Agomepratin on the basis of a second-generation antipsychotic drug (olanzapine, aripiprazole, risperidone, etc., see Annex A), and the control group will either use a second-generation antipsychotic drug (olanzapine, aripiprazole, risperidone, etc.) for 24 consecutive weeks, To explore the efficacy and safety of the second generation antipsychotic drugs combined with agomeratine regimen in the real world for negative symptoms of schizophrenic patients. Group sequential design is used as the method of interim analysis in the research process. If the research purpose is reached in advance, the research can be terminated. The study followed GRACE standards.

Around 40% of schizophrenia patients present depressive symptoms, which are associated with elevated suicide and violence risk and poor prognosis and quality of life. Recent meta-analysis showed the effect size of antidepressants for depressive symptoms of schizophrenia patients was as low as 0.25, so new therapeutic approach is warranted. Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive, anesthesia-free brain stimulation therapy for treatment refractory depression. Currently, rTMS is classified as high-frequency stimulation (>5Hz, usually 10Hz or 20Hz) and low-frequency inhibition (usually 1Hz). Intermittent theta burst stimulation (iTBS) is a new variant of rTMS, with stimulation frequency as high as 50Hz. Compared with high-frequency rTMS, iTBS has similar therapeutic effect and shorter stimulation duration. Up to now, studies exploring treatment effect of rTMS or iTBS for schizophrenia patients mainly focused on negative symptoms rather than depressive symptoms. Therefore, this study aims to explore treatment effect of rTMS or iTBS of depressive symptoms, negative symptoms, cognitive function and physiological indices for schizophrenia patients.

This a randomized double-blind placebo controlled trial which aims to determine the beneficial effects of minocycline augmentation to clozapine in partial responders to Treatment Resistant Schizophrenia (TRS).

In this study, the investigators will investigate the effect and the underlying mechanism of metformin treatment on cognitive impairment in individuals with schizophrenia. The study will recruit 120 individuals with schizophrenia at 4 sites, who will be randomized to metformin or placebo group for 24-week treatment. Clinical assessments will be done at screen/baseline, 12th week and 24th week. The specific aims are to compare metformin group versus controls on: 1) cognition; 2) clinical core symptoms. Biological samples also will be collected and stored to explore related mechanisms.

Establish a novel vocational training program and test its validity in a pilot study.

Dextromethorphan acts as N-methyl-D-aspartate (NMDA) antagonist. In Treatment resistant schizophrenia(TRS) the efficacy of treatment response by clozapine is only around 40%. Numerous augmentation agent have been tried which includes antipsychotics, anticonvulsants, antidepressants and NMDA antagonist. The NMDA antagonist such as Riluzole and Memantine have shown good efficacy in TRS. Therefore we are evaluating NMDA antagonist, dextromethorphan in TRS. The dextromethorphan or placebo will be administered along with clozapine in TRS patients. The study is randomized double blind placebo controlled group sequential trial.

Lyndra Therapeutics, Inc. is developing LYN-005, a long-acting oral (LAO) capsule (LYNX™ dosage form) of risperidone. This pivotal study (LYN-005-C-301) will evaluate the PK as well as safety and tolerability of multiple administrations of the LYN-005 formulation at two dose levels.
