NCT03382639
The purpose of this study is to determine whether add-on luvadaxistat is superior to placebo on the Positive and Negative Syndrome Scale Negative Symptom Factor Score (PANSS NSFS).
NCT02823041
This is a confirmatory randomized controlled trial of the efficacy of a novel intervention combining neuroplasticity-based cognitive training with aerobic exercise, compared to the same systematic cognitive training alone. Treatment occurs for 6 months after randomization, with a followup assessment at 12 months. The investigators hypothesize that combining neuroplasticity-based computerized cognitive training and neurotrophin-enhancing physical exercise will produce neurotrophin increases and cognitive and functional improvements, even relative to cognitive training alone. The investigators target the period shortly after a first episode of schizophrenia to maximize the generalization of cognitive improvement to functional outcome, before chronic disability is established.
NCT01431326
Understudied drugs will be administered to children per standard of care as prescribed by their treating caregiver and only biological sample collection during the time of drug administration will be involved. A total of approximately 7000 children aged \<21 years who are receiving these drugs for standard of care will be enrolled and will be followed for up a maximum of 90 days. The goal of this study is to characterize the pharmacokinetics of understudied drugs for which specific dosing recommendations and safety data are lacking. The prescribing of drugs to children will not be part of this protocol. Taking advantage of procedures done as part of routine medical care (i.e. blood draws) this study will serve as a tool to better understand drug exposure in children receiving these drugs per standard of care. The data collected through this initiative will also provide valuable pharmacokinetic and dosing information of drugs in different pediatric age groups as well as special pediatric populations (i.e. obese).
NCT02505477
The purpose of this study is to attempt to treat cognitive and negative symptoms of schizophrenia, with the nutritional supplement N-acetylcysteine (NAC). Schizophrenia is a chronic mental disorder that affects approximately 65 million people worldwide, and causes significant disability and suffering. Patients with schizophrenia often hear voices and have persecutory delusions. Though these are the most recognizable features of the illness, the deficits most closely linked to disability are known as cognitive deficits and negative symptoms. Cognitive abilities refer to the ability to perform mental tasks that require focus and attention, and also include memory and verbal skills. Negative symptoms refer to a lack of interest in the world, and decreased social interactions. In our study, the investigators aim to improve these symptoms and deficits by targeting the glutamate system. Glutamate is the major excitatory neurotransmitter in the brain, and its regulation is abnormal in schizophrenia: glutamate levels are too low at some receptors, and too high at others. As well, free radicals surrounding glutamate receptors also interfere with their proper function. N-acetylcystine (NAC) is a safe and widely-available dietary supplement that may restore glutamate to its correct levels in the brain, and may also help protect the brain from antioxidant damage. In our study, patients with schizophrenia will be randomly assigned to receive either NAC or placebo for 8 weeks. Brain levels of glutamate and an important antioxidant, glutathione, will be measured before and after treatment, using a neuroimaging technique known as magnetic resonance spectroscopy. Cognitive and negative symptoms will also be assessed before, during and after treatment. The investigators hypothesize that glutamate and glutathione will be normalized in patients' brains, and that their negative and cognitive symptoms will be improved, too.
NCT04659174
This is a Phase 3, multicenter, 53-week, outpatient, open-label extension (OLE) study to evaluate the long-term safety, tolerability, and efficacy of KarXT in subjects with Diagnostic and Statistical Manual-Fifth Edition (DSM-5) schizophrenia who previously completed the treatment period of one of the two Phase 3 double-blind studies, KAR-007 or KAR-009. In this OLE study, all subjects will receive KarXT (a fixed combination of xanomeline 125 mg and trospium chloride 30 mg twice daily \[BID\]) for up to 52 weeks regardless of treatment assignment in the preceding Phase 3 acute study. The primary objective of the study is to assess the long-term safety and tolerability of KarXT in subjects with a DSM-5 diagnosis of schizophrenia. The secondary objective of this study is to assess the long-term efficacy and monitor trough concentrations of xanomeline and trospium after administration of KarXT.

NCT04030143
The purpose of this trial is to determine the safety and tolerability of multiple-dose administrations of aripiprazole, to establish the similarity of aripiprazole concentrations on the last day of the dosing interval following the final administration of aripiprazole into the gluteal muscle site, and to establish the similarity of aripiprazole exposure over the dosing interval following the administration of aripiprazole into the gluteal muscle site in adult participants with schizophrenia or bipolar I disorder.
NCT04959032
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group, fixed-dose study in adult patients with a primary diagnosis of schizophrenia according to criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, (DSM-5).
NCT03859973
This is a study in adults with schizophrenia. The study tests whether a medicine called BI 425809 together with brain training improves mental abilities. Participants take study medication once a day for 12 weeks. At the start of the study, the participants are put into 2 groups. It is decided by chance who gets into which group. One group gets BI 425809 tablets every day. The other group gets placebo tablets every day. Placebo tablets look like the BI 425809 tablets, but contain no medicine. During the study, all participants do brain training using a computer. The doctors regularly test mental abilities of the participants. The results of the mental ability tests are compared between the groups. The doctors also check the general health of the patients.
NCT01291511
The purpose of this study is to determine whether Iloperidone is effective in the prevention of relapse in patients with schizophrenia
NCT03995368
This proposal will examine measures of neuroplasticity (the brain's ability to alter its function or structure in response to changes in the environment or novel experiences) in Veterans with schizophrenia or traumatic brain injury (TBI). Both conditions are associated with impaired cognition (for example, attention, memory, learning), which is in turn associated with poor community functioning and integration. However, the two disorders differ in their origins: schizophrenia is a neurodevelopmental disorder appearing usually in late adolescence while TBI is an acquired disorder as the result of an injury to the head. Understanding of the root causes of complex cognitive impairments associated with these disorders remains limited. Neuroplasticity is a fundamental brain process that underlies cognitive functioning and may give insight into the causes of cognitive dysfunction in TBI and schizophrenia. Neuroplasticity will be measured using electroencephalography (EEG) by placing small electrodes on the scalp that record the brain's electrical activity. Participants will listen to simple auditory tones and view simple visual patterns while their EEG is recorded. Additionally, participants will have measures of cognition and clinical interviews for diagnosis of a disorder as well as any current levels of symptoms.
NCT02022462
The mortality rate among people with Serious Mental Illness (SMI) is 2 to 3 times that of the general population, meaning that those with a serious mental illness die, on average, 25 years earlier than those without an SMI. These deaths are largely attributed to preventable medical conditions, many of which are more common in the SMI population. The "Bridge" intervention is a peer navigator model that was developed to target factors that negatively impact healthcare access, utilization, and outcomes among individuals with serious mental illness (e.g., severe mood disorders and psychotic disorders). This intervention targets male and female, adult consumers across races/ethnicities and has been utilized by Pacific Clinics (Southern California's largest behavioral healthcare agency) and the Department of Mental Health of Los Angeles County to improve the health and quality of life for their consumers. Investigators will test the comparative effectiveness of a peer navigator intervention (the Bridge) to treatment as usual. The Bridge navigator intervention is designed to teach SMI consumers the skills to engage health care providers and to overcome motivational deficits in order to improve their health and healthcare use. The specific aims of this application are: 1. To use randomized methods to examine the effectiveness of the Bridge intervention on the health care utilization, satisfaction with care, health status, and health care self-management for a sample of individuals with severe mental illness receiving public mental health services in the community; 2. To use randomized methods to examine the effectiveness of the Bridge intervention on psychological and social well-being for a sample of individuals with severe mental illness receiving public mental health services in the community. 151 participants in an Full Service Partnership (FSP) clinic operated by Pacific Clinics were recruited to participate in an approximately 24-month long study of Bridge navigation. Participants will be randomly assigned to either treatment as usual (waitlist) or immediate intervention with the Bridge. Participants in both groups will complete three assessments (baseline, 6 months, 12 months) and statistically compared over time. Staff stakeholders (n = 20) will also be interviewed at baseline and every three months of the study in order to ensure that the intervention is being implemented appropriately.
