Clozapine

The purpose of this research study is to compare (vs. treatment as usual) a brief (6-session), empirically supported, and highly disseminable version of digital (i.e., smartphone or web-based) cognitive behavioral therapy for insomnia (dCBT-I), called SleepioTM, in suicidal adolescents with co-occurring insomnia during the high-risk post-hospitalization period. Suicide is the 2nd leading cause of death among adolescents. Sleep problems, such as insomnia symptoms-the most common sleep problem in youth-may be a particularly promising treatment target to reduce suicide risk in adolescents. The investigators propose to test the feasibility, acceptability, and effectiveness of dCBT-I in a two-site (Rutgers and Old Dominion University) pilot study trial. Adolescents, 14-18 years-old, recently hospitalized for suicide risk with co-occurring insomnia (n=80, 50% at each site), will receive either dCBT-I (six weekly, 20-minute sessions) plus post-hospitalization treatment-as-usual (TAU) or TAU alone. Adolescents will complete assessments pre-treatment, during the treatment phase including at the end of treatment, and 1-month follow-up post-treatment.

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

The purpose of this study is to characterize the effect of KarXT on voiding dynamics and urological safety in participants with DSM-5 schizophrenia.

The goal of this basic experimental research study is to examine how the human thalamus supports flexible thinking and behavior. Specifically, the research aims to elucidate how the mediodorsal (MD) thalamus encodes and updates "context"-the mental framework that determines which rules or actions are relevant in a given situation. This work may contribute to understanding why certain psychiatric conditions, such as schizophrenia and ADHD, involve difficulties with cognitive flexibility and control. The primary research questions are: Does the MD thalamus represent the context that organizes how working memory guides task selection? Does the MD thalamus signal when context needs to be updated after a change in task demands? Do these thalamic representations support generalization to new situations or rules? Participants will complete cognitive tasks while undergoing high-resolution brain imaging using 7-Tesla MRI. The investigators will combine behavioral data, computational modeling, and advanced neuroimaging analyses to examine how the thalamus interacts with the cortex during flexible decision-making.

This is a prospective, 12-week, randomized, double-blind, placebo-controlled study, designed to evaluate the efficacy, safety, and tolerability of a dose of evenamide of 15 mg bid, compared to placebo, as add-on treatment in patients with documented treatment-resistant schizophrenia (TRS) who have prospectively demonstrated inadequate response to their current stable therapeutic dose of an antipsychotic(s). Approximately 400 patients will be randomized equally (1:1) to each of the two treatment groups in this study.

The central hypothesis is this: DMN connectivity can be modulated with inhibitory cTBS when delivered on an accelerated treatment schedule. This study seeks to provide evidence that accelerated, network-targeted inhibitory stimulation of the DMN leads to both altered network activity and a concomitant behavioral change in cognitive performance in individuals with schizophrenia and schizoaffective disorder. This study will also compare the effect of inhibitory cTBS in healthy individuals, as it may also lead to both altered network activity and a behavioral change in cognitive performance in individuals without schizophrenia or schizoaffective disorder. If successful, this study will have identified a safe, effective, and broadly applicable treatment for cognitive impairment in schizophrenia that has potential for translation into many other psychiatric and neurodevelopmental disorders, such as autism.

Schizophrenia is a common and severe psychiatric illness characterized by extreme disturbances of cognition and thought, affecting language, perception and sense of self. This study will assess adverse events, change in disease activity, and how oral emraclidine moves through the body in adult participants with schizophrenia Emraclidine is an investigational drug being developed for the treatment of schizophrenia. Participants are placed in one of two parts, Part A or Part B, where each group will receive a different treatment. Participants will receive either oral emraclidine or placebo. Approximately 258 participants will be enrolled across roughly 32 sites in the United States. Participants in Part A will be assigned to one of multiple ascending doses of emraclidine or placebo administered orally for 14 days or up to 21 days. Participants in Part B will receive Emraclidine or placebo administered orally for up to 42 days. Participants will be followed for 30 days after the last dose of the study drug. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

This study is a randomized controlled trial evaluating the impact of financial incentives on medication adherence among individuals with schizophrenia, schizoaffective disorder, or bipolar disorder and/or co-occurring substance use disorder who are recently discharged from involuntary hospitalization or are at high risk of future involuntary hospitalization. Participants will be randomized to receive financial incentives for adherence to long-acting injectable medications or to a control group.

This study will evaluate the efficacy of valbenazine on clinician- and patient-reported outcomes in participants with TD while receiving or after stopping a VMAT2 inhibitor.

The primary objective for this study is to evaluate the efficacy of NBI-1117568 compared with placebo on improving behavioral and psychological symptoms of schizophrenia in adults.

The purpose of this study is to evaluate the effectiveness of a psychosocial intervention called iTEST for people with psychotic disorders that targets introspective accuracy, or the ability to accurately gauge ones abilities. iTEST combines daily cognitive training on a mobile device with coaching that addresses recovery goals. In this trial, we will randomize people to one of two interventions conditions, iTEST or a control condition that receives coaching and cognitive training that does not emphasize introspective accuracy. Both interventions will take place over 12 weeks and participants will be asked to complete assessments at baseline, 6 weeks, 12 weeks, and 24 weeks. The primary outcome of the study is community functioning. Participants will be from three metropolitan areas: San Diego, Dallas, or Miami.

The purpose of this study is to evaluate the dose levels, safety, and drug levels of KarXT intramuscular injection in participants with Schizophrenia
