Active clinical trials for "Schizophrenia"

The Recognition and Prevention (RAP) Program is conducting a research study comparing an antidepressant, sertraline, alone versus in combination with a second-generation antipsychotic, risperidone, to evaluate their ability to reduce unusual thoughts, suspiciousness and other unusual experiences, to improve reasoning ability, memory, attention and social skills in adolescents.

The purpose of this research is to see if daily combination treatment of L-arginine and Kuvan changes brain chemistry in people experiencing schizophrenia as measured by MRS brain scans.

Repetitive Transcranial Magnetic Stimulation (rTMS) can modulate neuronal activity and has been shown to improve symptoms in patients with schizophrenia, but the underlying neural mechanism is unknown.This study hypothesized that repetitive transcranial magnetic stimulation of the cerebellar vermis can alter the ciliary-related functional connections in schizophrenia, thereby improving negative symptoms, cognitive function, and emotional symptoms. Therefore, this study will firstly explore the difference in cerebellar functional connectivity between patients and healthy controls, and on this basis, patients undergo a resting state functional magnetic resonance scan before and after rTMS intervention in the cerebellar vermis, and observe the cerebellar function connection in the treatment. Before and after changes, analyze the relationship between these changes and clinical efficacy to explore the neural mechanisms of efficacy.

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.

The purpose of this study is to determine the pharmacokinetics (PK), tolerability and safety of brexpiprazole LAI following a single administration in subjects with schizophrenia.

This study proposes to conduct a clinical trial comparison of olanzapine and the combination of a nicotinic cholinergic agonist, 3-[2,4-Dimethoxybenzylidene]anabaseine (DMXB-A) with a dopamine D2 receptor antagonist, the mechanism common to all antipsychotic drugs, to test the hypothesis that 7-nicotinic receptor agonism may be an additional necessary factor that enhances the efficacy of olanzapine that allows its slight superiority to risperidone. This trial would enroll patients taking olanzapine and record baseline measurements of clinical symptoms, cognition, metabolic parameters, and extrapyramidal side effects. The subjects would then be randomized to receive either risperidone or risperidone plus DMXB-A for 6 weeks and then would again have measurements of clinical symptoms, cognition, metabolic parameters and extrapyramidal side effects.

This study aims to develop a method for the assessment of central NMDA receptor functioning in patients with depression and schizophrenia. For this purpose a transitional approach is used based on preclinical studies that show a dose-dependent relationship between the activity of hypothalamic NMDA receptor and plasma AVP response to increasing plasma osmolality. Patients with schizophrenia, depression and healthy controls participated in this study. The Investigators found that in a subgroup of patients with schizophrenia the AVP response was low and that in a subgroup of subjects with depression the AVP response was high compared to healthy controls.

Current antipsychotics have only a limited effect on two core symptoms of schizophrenia, negative symptoms and cognitive deficits. Minocycline is a second-generation tetracycline which has a beneficial effect in various neurological disorders. Recent findings in animal models and human case-reports suggest its potential for the treatment of these symptoms of schizophrenia. The current study aims to examine the efficacy of minocycline as add-on treatment for alleviating negative and cognitive symptoms in early-phase schizophrenia. The study will utilize a longitudinal double blind, randomized, placebo-controlled design with patients followed for six-months. Early-phase schizophrenia patients were recruited and randomly allocated to a minocycline or placebo treatment (2:1 ratio; 200 mg/day). The primary outcome measures are the Scale for Assessment of Negative Symptoms (SANS) and assessments of executive functions.

The study will assess the use of paliperidone palmitate compared with oral antipsychotic treatment in delaying time to a protocol-defined treatment failure over 15 months, in patients diagnosed with schizophrenia who have been incarcerated.

The purpose of the study is to determine whether there is an increased all-cause mortality in sertindole-treated patients in comparison to patients treated with a well-known antipsychotic (risperidone) when used under normal marketed conditions in the treatment of schizophrenia.
