Schizophrenia

The purpose of this study is to assess the efficacy and safety of brenipatide when administered with standard of care (SoC) compared to placebo plus SoC for treatment of schizophrenia. The trial is divided into three periods as follows: Screening period will last approximately 1 month, treatment period will last a maximum of 12 months, and the follow up period will last approximately 2 months. The length of time of your study participation may last up to approximately 15 months.

The purpose of this study is to evaluate the safety and preliminary effectiveness of a smartphone-based digital therapeutic application (AffectUs) for improving social cognition, particularly emotion processing and social cue perception, in individuals with schizophrenia spectrum disorders. In this randomized controlled trial, participants will be assigned either to use AffectUs for 10 weeks in addition to treatment as usual or to receive psychoeducational materials and treatment as usual. Participants will complete assessments at baseline, week 5, week 10, and week 15 to evaluate social cognition, clinical outcomes, and safety.

The purpose of this clinical trial is to learn whether the investigational drug LTX-001 is safe and well tolerated in adults with a diagnosis of schizophrenia who are having a recent worsening of their symptoms (an acute exacerbation). Additional questions it aims to answer are: * how does the amount of the study drug in the body change over time (pharmacokinetics) * how does the study drug affect the symptoms of schizophrenia * how do certain markers in the blood change after administration of LTX-001 (pharmacodynamics) Researchers will compare different dose levels of LTX-001 to an inactive product (placebo) to see what differences there are between the two treatments. After successfully screening for the study, participants will stay in a research unit for about five weeks and return one week later for a follow-up visit.

The purpose of this study is to describe real-world treatment patterns, effectiveness and adverse events of adults diagnosed with schizophrenia that have initiated xanomeline and trospium chloride (KarXT) treatment in the United States

The purpose of this study is to understand treatment preference and satisfaction among adults with schizophrenia in the United States who are prescribed xanomeline and trospium chloride (X/T) therapy

The goal of this clinical trial is to learn about cognition in psychotic disorders (schizophrenia, bipolar disorder, and schizoaffective disorder). The main question it aims to answer is: Can we use magnetic stimulation to change processing speed (how quickly people can solve challenging tasks). Participants will be asked to perform cognitive tasks (problem-solving) and undergo brain scans before and after transcranial magnetic stimulation (TMS). TMS is a way to non-invasively change brain activity. Forms of TMS are FDA-approved to treat depression and obsessive compulsive disorder. In this study, we will use a different form of TMS to temporarily change brain activity to observe how that changes speed in problem-solving.

People with mental disorders face frequent stigmatizing attitudes and behaviors from others . In response to this, they tend to isolate themselves, with the risk of impeding care and the process of recovery and integration into society . Stigmatization can also be assimilated by patients themselves - i.e. self-stigma. Self-stigma is involved in diminished coping skills that lead to social avoidance and difficulties in adhering to care . Reducing self-stigma and its emotional corollary, shame, is thus crucial to attenuate the disability associated with mental illness. Shame is inherent to self-stigma and leads to difficulties in adhering to care as well as greater severity of clinical presentations . Compassion Focused Therapy (CFT) is a third wave cognitive behavioral therapy that targets shame reduction and hostile self-to-self relationship and allows for symptom improvement while increasing self-compassion, a major resilience factor . Although shame is a prominent part of the concept of self-stigma, the efficacy of CFT has never been evaluated in individuals with high levels of self-stigma. In this study, the investigators will evaluate the efficacy and acceptability of a group based CFT program on decreasing self-stigma, compared to treatment as usual (TAU) and a psychoeducation program whose efficacy has been assessed in a previous trial.

Over 60% of Veterans with serious mental illness have a service-connected disability that impairs their ability to work, go to school, and/or have successful personal lives. Although traditional treatments tend to focus on symptom remission, Veterans prioritize a range of treatment goals, including personal empowerment and gaining personally meaningful skills. Increasing Veteran-clinician collaboration can help effectively align care with each Veteran's goals and support an empowering therapeutic experience. This project will evaluate the effectiveness of a group-based intervention intended to increase Veterans' comfort, confidence, knowledge, and skills to collaborate with their treatment teams. Findings from this study will contribute important knowledge about this intervention's effectiveness and how to enhance its effectiveness, especially for Veterans from minoritized groups. If the decision-making intervention is effective, it would help Veterans with serious mental illness, and might also help Veterans with other chronic health conditions, like PTSD and chronic pain.

The purpose of this study is to understand how different types of community-based mental health care affect thinking abilities, daily functioning, and brain activity in adults with schizophrenia and related conditions. The investigators are especially interested in learning whether the Clubhouse Model-a structured, supportive community for individuals with mental illness-has unique benefits compared to standard outpatient mental health services. If participants decide to join, they will be asked to complete a total of six study visits with the research team over the course of your participation. Three of these study visits are at the beginning (baseline) and the remaining three are six months later. Two of the three visits will includes interviews, questionnaires, and thinking and memory tasks (cognitive testing) and one session will be an MRI brain scan, which is a safe and non-invasive imaging procedure. The total time required for each visit will be approximately 90 minutes to two hours. Participants may take breaks as needed.

The aim of the study is to assess the treatment effects of deep active repetitive transcranial magnetic stimulation (rTMS) with H4 coil combined with cognitive training for improving frontal white matter microstructural integrity in patients with schizophrenia spectrum disorder (SSD).

Antipsychotic medications are widely used to treat schizophrenia but may cause constipation, which can lead to abdominal discomfort, reduced quality of life, and poor treatment adherence. Xingqi Daozhi Decoction is a traditional Chinese medicine formula used to relieve constipation associated with qi stagnation. This study aims to evaluate the effectiveness and safety of Xingqi Daozhi Decoction for antipsychotic-induced constipation with a qi stagnation pattern. This is a single-center, randomized, double-blind, placebo-controlled exploratory study. A total of 46 participants with schizophrenia who developed constipation after taking antipsychotic medications will be enrolled. Participants will be randomly assigned to receive either Xingqi Daozhi Decoction granules or matching placebo granules twice daily for 8 weeks. Neither the participants nor the treating clinicians and outcome assessors will know the treatment assignment during the study. Participants will be evaluated regularly during treatment. The study will assess changes in bowel movements, constipation symptoms, constipation-related quality of life, and treatment safety. Participants will also undergo routine clinical and laboratory safety assessments, and adverse events will be recorded throughout the study. The primary outcome focuses on the proportion of participants who achieve an improvement in complete spontaneous bowel movements during treatment.

The purpose of this study is to evaluate the long-term safety and tolerability of KarXT and KarX-EC for the treatment of Schizophrenia and autism-related irritability in adolescents, respectively

The purpose of this study is to evaluate the efficacy and safety of KarXT for treatment of Schizophrenia in adolescents.

This study will consist of 2 parts: Part Ⅰ-in healthy adult subjects, Part Ⅱ-in adult patients with schizophrenia

To compare changes in body mass index (BMI) Z-score following treatment with OLZ/SAM vs olanzapine

ML-007C-MA-212 is a 52-week open-label study designed to evaluate the long-term safety, tolerability, and effectiveness of ML-007C-MA in participants with schizophrenia who have recently completed an antecedent study (ML-007C-MA-211) or enroll directly (De Novo Cohort).

This is a multicenter, global, 26-week, open-label study to assess the safety and tolerability of lumateperone in pediatric patients with schizophrenia, bipolar disorder or autism spectrum disorder.

This study will investigate the effects of intermittent Theta Burst Stimulation (iTBS) on natural oscillatory frequency of the dorsolateral prefrontal cortex (DLPFC) and working memory in early-course schizophrenia (EC-SCZ). Transcranial magnetic stimulation (TMS) will be used to evoke oscillatory activity, and EEG will record the responses of EC-SCZ participants. A working memory task will also be incorporated in order to determine how DLPFC natural frequency (NF) is related to working memory performance. iTBS (active or sham) will be administered, then the oscillatory activity of DLPFC and working memory performance will be reassessed. The overarching goal is to determine whether iTBS can acutely enhance the oscillatory activity of the DLPFC and to evaluate the relationship between changes in the DLPFC and working memory performance.

This is a study of the efficacy and safety of BXCL501 in children and adolescents with acute agitation and either bipolar disorder or schizophrenia.

This study to find out whether a type of non-invasive electrical brain stimulation called transcranial electrical stimulation with temporal interference (TES-TI) can temporarily change brain activity during sleep-especially sleep spindles (brain rhythms in the \~8-16 Hz range). The investigators are focusing on the thalamus, a deep brain region that helps coordinate brain activity during non-REM sleep. Sleep spindles are often reduced in schizophrenia, so this study is to see whether TES-TI can change spindle activity in individuals with schizophrenia spectrum disorders (SSD) and in healthy adults. To study this, a structural MRI scan will be used to customize where the stimulation electrodes are placed, and then TES-TI will be applied during one of two overnight sleep lab visits while brain activity is recorded with high-density EEG and standard sleep sensors. The other overnight is a baseline/control night during which only sham stimulation is delivered. The goal is to determine whether TES-TI during sleep can increase spindle-frequency activity in this population.

Individuals with schizophrenia often experience persistent auditory hallucinations despite treatment with antipsychotic medications. Research suggests that abnormal communication between the striatum and the auditory cortex contributes to hallucinations. This first-in-human, proof-of-concept Phase 1 study will evaluate the safety, feasibility, and preliminary effects of repeated-session low-intensity focused ultrasound (LIFU), a non-invasive neuromodulation technique targeting the striatum. The study will examine whether LIFU can safely modulate brain circuits involved in hallucinations, reduce abnormal communication between the striatum and auditory cortex, and improve auditory hallucination symptoms.

The participants in the study will receive psychiatric treatment at the UCLA Aftercare Research Program. All participants in this 12-month RCT will receive cognitive training. Half of the patients will also be randomly assigned to the aerobic exercise and strength training condition, and the other half will be randomly assigned to the Healthy Living Group condition. The primary outcome measures are improvement in cognition and level of engagement in the in-group and at-home exercise sessions. Increases in the level of the patient's serum brain-derived neurotropic factor (specifically Mature BDNF) which causes greater brain neuroplasticity and is indicator of engagement in aerobic exercise, will be measured early in the treatment phase in order to confirm engagement of this target. In order to demonstrate the feasibility and portability of this intervention outside of academic research programs, the interventions will be provided via videoconferencing. The proposed study will incorporate additional methods to maximize participation in the exercise condition, including the use of the Moderated Online Social Therapy (MOST) platform to enhance motivation for treatment based on Self-Determination Theory principles, and a "bridging" group to help the participants generalize gains to everyday functioning. In addition, the exercise group participants will receive personally tailored text reminders to exercise.

The study will investigate the (1) additive and synergistic effects of tDCS and aerobic exercise on cognitive function and clinical symptoms in schizophrenia, and (2) neurophysiological mechanisms (mediators) underlying these effects.

Schizophrenia is a severe mental illness associated with significant morbidity and disability. Patients often experience metabolic side effects from antipsychotic medications, including weight gain and dyslipidemia. Statins, commonly used to manage dyslipidemia, can lower cholesterol levels but may increase the risk of new-onset diabetes. This study aims to investigate how atorvastatin affects glucose metabolism in schizophrenia patients and assess whether metformin can help improve these metabolic issues. The investigators will include 200 patients with dyslipidemia from the Second Xiangya Hospital and other sites, randomly assigning them to receive either atorvastatin with metformin or atorvastatin with placebo over six months. Key goals include evaluating the impact of atorvastatin on insulin resistance and blood glucose levels and determining the effectiveness of metformin in mitigating glucose metabolism abnormalities while managing lipid levels. Understanding these interactions will help improve treatment strategies for schizophrenia patients, potentially lowering their risk of cardiovascular diseases and diabetes and enhancing overall health outcomes.
