NCT03077347
The purpose of this study is to better understand the neural correlates of cognitive control (CC) deficits in schizophrenia and determine how these mechanisms can be modulated by transcranial direct current stimulation (tDCS). CC is a critical neurocognitive process that is required for flexible, directed thought and action based on goals and intentions. Identifying and developing paradigms to improve CC is therefore a mental health priority. Current theories of CC postulate that recruitment of the dorsolateral prefrontal cortex (DLPFC) is essential for this process by maintaining high-level information that it can then use to orchestrate patterns of activation in other brain networks to support optimal performance. tDCS is a safe, noninvasive method of modulating regional brain excitability via brief (15-20 m) application of a weak (1-2 mA) current. The goal of the proposed experiments is to combine tDCS with functional magnetic resonance imaging (fMRI) to test the hypotheses that 1) acute tDCS over the DLPFC can improve performance during a CC task (the dot pattern expectancy (DPX) variant of the AX-Continuous Performance Task) in schizophrenia patients and healthy control subjects, and 2) acute tDCS over the DLPFC can increase recruitment of the DLPFC during the DPX. Effects of tDCS on brain functional connectivity (during CC as well as during the resting state) will also be examined, as well as effects on an episodic memory task. The current study will be the first to use functional magnetic resonance imaging (fMRI) to examine the effects of tDCS on the neuronal mechanisms of CC in schizophrenia, and has potentially important implications for therapeutic development for this treatment refractory yet disabling aspect of the illness.
NCT05643170
This is a Phase 3b, 3-year, open-label, multi-center study in which patients with DSM-5 diagnosis of schizophrenia whose current medication(s) is not well tolerated and/or clinical symptoms are not well controlled will be switched to receive KarXT. The primary objectives of the study are to assess the long-term safety and tolerability of KarXT and assess effectiveness, persistence, and durability of effect of KarXT through the Investigator Assessment Questionnaire (IAQ) and Clinical Global Impression - Severity of Illness (CGI-S) scale in patients with a diagnosis of schizophrenia. The secondary objectives are to further assess the effectiveness using the Clinical Global Impression, Global Improvement (CGI-I), long-term safety and tolerability of KarXT, and evaluation of scores from multiple additional patient scales and assessments throughout the study.
NCT03260257
Schizophrenia affects 2.4 million Americans and causes significant individual and societal costs. Cognitive deficits including poor working memory arise early in the course of illness, account for poor long-term outcomes and have been difficult to treat with available treatments. The investigators are proposing to develop a novel, computer-based brain training to improve working memory in schizophrenia patients, which, if successful could have significant personal, societal, and economic impact.
NCT06431009
The objective of this study is to recruit patients at the first diagnosis with a schizophrenia spectrum disorder (SSD) and ultra-high risk patients (UHR), defined as patients with drug abuse and psychotic symptoms indicating a risk for developing schizophrenia. Thereby, the investigators aim to establish a large representative cohort of patients with a first-episode SSD or patients at UHR, enabling investigations of the etiology and long-term prognosis of SSDs. The primary aim is to learn more about the importance of adverse childhood experiences (ACEs) and the immune system in the etiology and course of schizophrenia. Patients will be followed with planned visits after 1, 2, 3, 12 and 24 months including online questionnaires after 2, 6, 10 and 26 weeks. There will be the possibility to contact patients again for subsequent follow-up visits.
NCT01142596
This is a multi-site, randomized fixed-flexible dose long-term study of asenapine in participants with schizophrenia. The first six weeks of the study will be double-blind and the remainder of the study will be open label. Participants in this study consist of participants who have completed the preceding short-term study (P06124 \[NCT01098110\]), who meet the inclusion criteria and wish to continue receiving study drug, and whom the investigators have deemed eligible for study participation. Participants who were on placebo twice daily (BID) in core trial P06124 will get placebo for the first 2 weeks then 5 mg asenapine BID for the next 4 weeks of double blind treatment, and will be re-randomized after week 6 to asenapine 5 mg BID or asenapine 10 mg BID. Participants who were on asenapine 5 mg BID in core trial P06124 will be re-randomized after Week 6 to asenapine 5 mg BID or asenapine 10 mg BID. Participants who were on asenapine 10 mg BID in core trial P06124 will be re-randomized after Week 6 to asenapine 5 mg BID or asenapine 10 mg BID. After re-randomization, drug will be administered open-label for 46 weeks. During this period dose is flexible can be adjusted using dose options of 5 and 10 mg BID for efficacy and tolerability.
NCT03974620
This study aims to test the hypothesis that addition of Individual Placement and Support (IPS) and/or Cognitive Remediation Therapy (CRT) in addition to treatment as usual in patients with early psychosis will be feasible and acceptable in patients with early schizophrenia.
NCT05252039
This pilot feasibility trial aims to evaluate the "Goals in Focus" intervention for motivational negative symptoms in people with psychosis. Goals in Focus interventions translate findings of basic clinical research on psychological mechanisms of motivational negative symptoms into a tailored and comprehensive novel psychological treatment program. The current single-blind randomized-controlled study aims to test feasibility and to examine first estimates of the expected effect size of Goals in Focus to inform a subsequent fully-powered RCT. The feasibility data will be used to improve on the trial design and the provision of the "Goals in Focus" intervention where necessary.
NCT04452175
Smokers with schizophrenia spectrum disorders have high rates of morbidity and mortality from smoking-related diseases compared with the general population and current options for smoking cessation in this vulnerable group are unsatisfactory. Considering that most people with schizophrenia spectrum disorders continue smoking, it is urgent to consider alternative and more efficient interventions to reduce or prevent their morbidity and mortality. Switching to combustion-free technologies for nicotine delivery (I.e. e-cigarettes) could be a pragmatic and much less harmful alternative to tobacco smoking with the possibility of significant health gains. Emerging research is suggesting that ECs may be useful for smoking cessation and relapse prevention in people with schizophrenia spectrum disorders. In particular, a study conducted with JUUL e-cigarette with 5% nicotine strength showed that this product had sufficient nicotine delivery and product appeal to determine high success rates in heavy smokers with schizophrenia spectrum disorders. In consideration of these preliminary findings, we hypothesized that switching smokers with a schizophrenia spectrum disorder diagnosis to JUUL e-cigarette with 5% nicotine strength could result in higher success rates compared to JUUL e-cigarette with 1.7% nicotine strength. Recent work indicates that nicotine PK of the JUUL e-cigarette with 5% nicotine strength (a device that utilizes a nicotine salt formulation) approximates the nicotine delivery of combustible cigarettes and that the 5% nicotine strength product is far more efficient in delivering nicotine compared to the sister product with 1.7% nicotine strength. Both products are identical in their appearance, making them suitable for a double-blind study design.
NCT02775864
The study is a retrospective cohort study of adults with schizophrenia that will compare outcomes of new users of alternative psychotropic medication strategies using 10 years of Medicaid data. The primary comparative effectiveness analyses will focus on subgroups of patients with schizophrenia facing common clinical situations.
NCT01425671
The principle aim of the project is to analyze brain electrical activity and genetic information that will help identify the nature and cause of the disease schizophrenia. This effort should lay the groundwork for future treatment in schizophrenic patients.
NCT01892384
The primary objective of the current study is to investigate the safety and tolerability of BI 409306 in schizophrenic patients following oral administration of multiple low, medium, and high doses over 14 days. A secondary objective is the exploration of the pharmacokinetics and pharmacodynamics of BI 409306 in schizophrenic patients.
NCT06349369
The study is a randomized, double-blind, parallel-arm, sham-controlled trial that aims to compare the effects of transcranial direct current stimulation (tDCS) versus sham stimulation on inflammatory markers (IL-6 and TNF-alpha) and clinical outcomes (PANSS, AHRS, CGI-SCH, GAF) in patients with chronic schizophrenia over 10 days of treatment. The primary objective is to assess changes in IL-6 levels, while secondary objectives include evaluating changes in TNF-alpha, symptom scales, and adverse events. The study will be conducted at the psychiatry department of AIIMS Bhubaneswar, with 60 patients aged 18-60 years with moderate-to-severe schizophrenia symptoms randomized to receive either active tDCS (cathode over left temporo-parietal junction, anode over left dorsolateral prefrontal cortex) or sham stimulation. The researchers hope to elucidate the potential immunomodulatory effects of tDCS and its impact on symptoms in chronic schizophrenia, which may lead to more targeted, multifaceted interventions to improve patient outcomes.
NCT01573637
The efficacy of raloxifene versus placebo was compared over a six-month period, as an adjuvant treatment of the negative symptoms of schizophrenia in a group of 80 post-menopausal women. The aim of the study is to analyze whether raloxifene has an effect on the positive and negative symptoms of schizophrenia, and on psychopathological symptoms in general, and on social and neuropsychological functioning, and to study the influence of genetic polymorphisms in treatment response.
NCT05598450
rTMS and MEG for auditory hallucinations via self controlled clinical trials. Repetitive transcranial magnetic stimulation (rTMS) can increase or decrease cortical excitability in patients with psychosis (such as schizophrenia). Here, we conducted an open clinical trial on 60 schizophrenics with auditory hallucinations. We searched for targets through magnetoencephalography and then intervened to prove that rTMS guided by magnetoencephalography is effective for auditory hallucinations.
NCT06336616
The goal of this study is to evaluate the effectiveness of an behavioral activation intervention to increase meaningful activity and community participation for people with serious mental illness. The overall objective of this study is to increase engagement in meaningful activities and community participation. The objectives of the project are as follows: 1. To determine if the intervention leads to increases the frequency and variety of activities. 2. To determine if the intervention leads to increases in community mobility. 3. To determine which demographic and environmental factors and mechanisms of action impact the effectiveness of the intervention. 4. To determine if the the intervention leads to an improvement in overall well-being (e.g., improved quality of life). Participants will be asked to attend a 2-hour weekly online session for 10 weeks and then a 1-hour online monthly session for a 3 month maintenance period. For data collection, participants will also be asked to: 1. Complete three, approximately 1-hour interviews at baseline, after the 10 week intervention, and again at the end of the maintenance period; 2. Carry a mobile phone with a global positioning system app to track their movements outside their home for 2 weeks at a time, at three separate times (e.g., baseline, after the intervention, and at the end of the maintenance period); and 3. Complete a 15 minute weekly interviews for 26 weeks about their daily activities and participation. The study will enroll 52 participants split into 4 cohorts of 13. The study will use a multiple baseline design and, as such, all participants will receive the intervention and there is no control group.
NCT05345977
Although the main objective of current schizophrenia intervention programs is the reduction of symptoms, its rates are around 36%, and recovery rates are 16.5%. Between 30 and 50% of people with schizophrenia obtain little benefit with conventional therapy. They are considered resistant to treatment. Therefore, the development of innovative evidence-based interventions adjunctive to pharmacological and psychological treatment are necessary for improving results in patients with treatment-resistant schizophrenia (TRS). Studies with digital solutions have shown feasibility, acceptability and even preliminary efficacy data. But no earlier published study has focused on TRS. The eMOTIPH is an innovative solution addressed to TRS and born from the outcomes of the previous study eMOTIPH Part 1 (study of beliefs, needs, and limitations associated with current intervention in TRS patients).
NCT06347848
In the fight against stigma, the focus should be on the education of individuals diagnosed with mental illness. Psychoeducation has an important place in the treatment and rehabilitation of mental health problems. Psychoeducation is necessary for early recognition of signs and symptoms of diseases, ensuring compliance with treatment, improving coping skills, as well as combating stigma, preventing internalized stigma, and counteracting social stigma. If individuals with mental disorders have adequate knowledge about the causes of stigma, they may be less prone to internalized stigma.
