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.

The goal of this clinical trial is to identify the specific characteristics (phenotypes) that may be useful to help select the right medication for weight loss, and to study the effect of individualized guided medication in patients with bipolar disorder ages 18-65. The main questions it aims to answer are: * Can the investigators compare the distribution of obesity characteristics (hungry brain, hungry gut, emotional hunger) between bipolar patients and non-bipolar participants (comparing from IRB #24-002375)? * Can the investigators evaluate the feasibility of anti-obesity medication (AOM) in patients with bipolar disorder? Participation will last for about 17-18 weeks and includes 7 in-person study visits, 4 phone call visits, and 12 virtual group therapy sessions. The first visit lasts about 2 hours and includes going over the informed consent form, a diagnostic interview to confirm diagnosis, gathering vital signs, mood questionnaires, an ECG, and urine drug and pregnancy tests (if applicable). The second visit lasts about 6-7 hours and involves multiple procedures and completing questionnaires to determine which study drug would allow participants to lose weight most effectively. At the third visit, participants will be assigned to take one of three FDA approved medications for weight loss: Semaglutide (Wegovy®), Naltrexone/Bupropion (Contrave®), or Phentermine/Topiramate (Qysmia®). It is possible that participants could be assigned to a group that receives no study medication. All participants will be enrolled in a 12-week virtual group therapy program targeted for weight loss. On this third visit the investigators will also gather vital signs, and participants will give a sample of blood. After the third visit, participants will come in for study visits every 4 weeks for 16 weeks (4 visits) to assess medication adherence, vitals, and answer questions about mood and eating (participants will also give a sample of blood at the 8-week and 16-week visits). Every two weeks in between in-person visits, the study team will call participants to assess medication adherence. Participants will be compensated for time spent in this study.

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 long-term safety of NBI-1117568 in adults with schizophrenia.

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 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

The goal of this study is to reduce Anticholinergic Medication (ACM) in persons with psychoses or serious mental illness, when these medications are no longer needed.

ML-007C-MA-211 is a Phase 2, randomized, double-blind, placebo-controlled study to evaluate the efficacy, safety, and tolerability of orally administered ML-007C-MA in inpatient adult participants aged 18 to 64 years with schizophrenia experiencing an acute exacerbation of psychosis. The primary objective is to evaluate the efficacy of ML-007C-MA compared with placebo in the treatment of subjects with inadequately controlled symptoms of schizophrenia as measured by the Positive and Negative Syndrome Scale (PANSS) Total Score.
