SchizophreniaSchizophrenia; PsychosisThis is a Phase 3, randomized, double-blind, parallel-group, placebo-controlled, multicenter inpatient study to examine the efficacy and safety of KarXT in adult subjects who are acutely psychotic with a Diagnostic and Statistical Manual Fifth Edition (DSM-5) diagnosis of schizophrenia. The primary objective of the study is to assess the efficacy of KarXT (a fixed combination of xanomeline 125 mg and trospium chloride 30 mg twice daily [BID]) versus placebo in reducing Positive and Negative Syndrome Scale (PANSS) total scores in adult inpatients with a DSM-5 diagnosis of schizophrenia. The secondary objectives of the study are to evaluate improvement in disease severity and symptoms, safety and tolerability, and pharmacokinetics in adult inpatients with a DSM-5 diagnosis of schizophrenia.

Targeting Physical Health in Schizophrenia: Physical Activity Can Enhance Life Randomized Control...
SchizophreniaSchizoaffective Disorder3 morePurpose: To test the effectiveness of an exercise intervention that combines group walking, activity tracking, and heart rate monitoring (i.e. Physical Activity can Enhance Life, PACE-Life) on the physical and mental health for individuals with schizophrenia spectrum disorder. Participants: 50 individuals with schizophrenia spectrum disorders. Procedures (methods): During the baseline assessment, which can be completed virtually and in-person (based on participant preference) all participants will be provided with a Fitbit wristband and instructed how to use it. During the first group session, participants will be taught how to use their heart rate (on the Fitbit) to determine how fast participants should walk (to achieve the appropriate exercise dosage). Information on proper care, usage, and how to determine the appropriate heart rate from the watch, to guide the intensity of the walk, will be provided to participants and reviewed at each group session. Participants randomly assigned to the PACE Life virtual walking group sessions will meet the other group members and group leaders and be reminded of the heart rate (HR) that corresponds with the intensity of that group session. Next, the group will exercise for 15 minutes in the first two weeks, progressing to 30-minute walking sessions over the course of the intervention. At the completion of the sessions, everyone will take a break for water and review the walk. After the second group session of each week, participants will receive weekly progress reports of their steps and minutes spent walking the prior week (obtained from Fitbit devices). During this session, participants will also set individual goals for the upcoming week for both their "intensity walks" and total steps per day. Participants randomly assigned to Fitbit Alone will be given a Fitbit and shown how to use it by study staff. Participants will also be given information on current recommended physical activity guidelines (150 min/week of moderate intensity exercise) and will be told that study staff may be contacting them on a weekly basis (or shorter, if necessary) if it looks like participants are not wearing their Fitbit for a certain number of days (e.g. 3 consecutive days) or to troubleshoot any issues. If necessary, participants might be invited to meet with research staff to get assistance on any Fitibit or exercise-related issues.

rTMS as a Probe of Episodic Memory Neurocircuitry in Schizophrenia
SchizophreniaThis will be a single site pilot study. 30 subjects with Early Phase Psychosis (EPP), defined as medical record documentation of the onset of clinically significant psychotic symptoms within the past ten years, will be enrolled. Prior to randomization (Session 1), subjects will undergo Functional Magnetic Resonance Imaging (fMRI) during Episodic Memory (EM) and Resting State (RS) paradigms. This baseline scan will also include a high-resolution structural sequence for neuronavigation purposes. Then on three separate days each occurring one-week apart, subjects will receive one session of inhibitory (1 Hertz [Hz]) Repetitive Transcranial Magnetic Stimulation (rTMS), one session of excitatory (20 Hz) rTMS, and one sham stimulation session targeting the precuneus. The order of the three interventions will be randomized. Immediately following each rTMS or sham session, subjects will undergo repeat fMRI during EM and RS paradigms. The investigators will also examine the effect of rTMS on EM performance.

Improving Cognition in Schizophrenia Using Non-invasive Brain Stimulation
SchizophreniaThis is a double-blind sham-controlled study to evaluate the effects of the combination of non-invasive brain stimulation, i.e. transcranial direct current stimulation (tDCS), with brief cognitive training (CT) on cognition in patients with schizophrenia. All participants will practice the same cognitive training tasks and will be randomised to either real tDCS or sham stimulation. Patients with schizophrenia will undergo the study interventions while maintaining their standard treatment with antipsychotic medications.

A Study of Paliperidone Palmitate 6-Month Formulation
SchizophreniaThe main purpose of this study is to assess the long-term safety and tolerability of paliperidone 6-month PP6M (Dose 1 or Dose 2 [milligram] mg eq.) and to provide access to PP6M in participants with schizophrenia completing the R092670PSY3015 study without relapse.

The Impact of Dietary Habits and Nutrition Intervention on Metabolic Syndrome in Individuals With...
Metabolic SyndromeMetabolic syndrome is a term used to describe a complex clinical condition that includes abdominal obesity, increased level of serum triglycerides, elevated blood pressure, decreased level of high-density lipoprotein cholesterol, and high fasting glucose level. Metabolic syndrome represents one of the major risk factors for the development of cardiovascular diseases and type 2 diabetes mellitus. According to the results of numerous previously conducted studies, the prevalence of metabolic syndrome among the individuals with schizophrenia is higher than in the general population. The reasons for the higher prevalence of metabolic syndrome among the individuals with schizophrenia are not yet fully clarified. Nevertheless, unhealthy dietary habits are considered to be one of the main factors that could have an impact on metabolic syndrome development. According to the results of published studies, individuals with schizophrenia have poorer dietary habits when compared to people without mental disorders. Although there are numerous previously published studies focused on the impact of nutritional interventions on metabolic syndrome in individuals with schizophrenia, there is still no consensus on what would be the most appropriate nutrition therapy for the treatment of metabolic syndrome in this specific population group. Furthermore, the vast majority of the published studies have been conducted on outpatients, with only a small number of them being carried out on hospitalized individuals with a diagnosis of schizophrenia. Dietary Approaches to Stop Hypertension (DASH) diet is primarily intended to those individuals with elevated blood pressure, but according to some authors, it could have beneficial effects in the treatment of the metabolic syndrome as well. DASH diet represents a healthy way of eating with a special emphasis on low-fat dairy products, fruits, vegetables and whole grains, together with an overall reduction in sodium intake. Therefore, the present study aims to determine the impact of dietary habits and nutrition intervention on metabolic syndrome parameters in hospitalized individuals with the diagnosis of schizophrenia. The investigators hypothesize that the intervention will result in the improvement in metabolic syndrome parameters, the amelioration in dietary habits, and the reduction in body weight.
