Filter by:This study is open to adults with schizophrenia. Schizophrenia can affect the way a person thinks, their memory and their mental functioning. Examples include struggling to remember things, or to read a book or pay attention to a movie. Some people have difficulty calculating the right change or planning a trip so that they arrive on time. The purpose of this study is to find out whether a medicine called Iclepertin improves learning and memory in people with schizophrenia. Participants are put into two groups randomly, which means by chance. One group takes Iclepertin tablets and the other group takes placebo tablets. Placebo tablets look like Iclepertin tablets but do not contain any medicine. Participants take a tablet once a day for 26 weeks. In addition, all participants take their normal medication for schizophrenia. During this time, doctors regularly test learning and memory of the participants by use of questionnaires, interviews, and computer tests. The results of the mental ability tests are compared between the groups. Participants are in the study for about 8 months and visit the study site about 14 times. During this time, doctors regularly check participants' health and take note of any unwanted effects.
This is a Phase 3, multicenter, 56-week, outpatient, open-label (OL) study to evaluate the long-term safety, tolerability, and efficacy of KarXT in de novo subjects with Diagnostic and Statistical Manual-Fifth Edition (DSM-5) schizophrenia. In this OL study, all subjects will receive KarXT (a fixed combination of xanomeline 125 mg and trospium chloride 30 mg twice daily [BID]) for up to 52 weeks. The primary objective of the study is to assess the long-term safety and tolerability of KarXT in subjects with a DSM-5 diagnosis of schizophrenia. The secondary objective of this study is to assess the long-term efficacy and characterize the pharmacokinetics of xanomeline and trospium after administration of KarXT.
The purpose of this study is to examine how Bayesian belief updating changes throughout psychotherapeutic treatment for persecutory delusions. Specifically, individuals with a psychotic disorder diagnosis who endorse both a current persecutory delusion with strong conviction and significant worry will be recruited and randomized to receive either a CBT-based worry intervention for persecutory delusions or an active control condition (befriending therapy). The investigators will examine: 1) whether belief updating parameters change as delusion severity changes, 2) whether CBT contributes to greater change in belief updating parameters than befriending therapy, and 3) whether neural correlates of belief updating parameters, as measured using functional magnetic resonance imaging (fMRI), predict treatment response.
The weight gain and metabolic dysfunction has been vital conditions for individuals with schizophrenia. rTMS is a promising novel intervention, which have strong potentials on moderating increased appetite and cognitive deficits in schizophrenia, as it has been proved for the treatment of depression. Therefore, the investigators designed this randomized controlled clinical trial to evaluate the efficacy and safety of rTMS, using iTBS pattern, on prevention and treatment for elevated appetite and cognitive deficiency in individual with schizophrenia.
Interventional study using Cannabidiol containing cigarettes as replacement of usual cigarettes Reduction of enforcement measures, improved acute treatment, harm reduction, and improvement of psychotic symptoms
The purpose of this study is to evaluate the efficacy and safety of MK-8189 at a range of doses (8 mg, 16 mg, and 24 mg once daily) in adult participants who have an acute episode of schizophrenia according to Diagnostic and Statistical Manual of Mental Disorders 5th Edition (DSM-5) criteria. The primary hypotheses are the following: (1) MK-8189 24 mg is superior to placebo in reducing the Week 6 mean change from baseline in Positive and Negative Syndrome Scale (PANSS) total score (2) MK-8189 16 mg is superior to placebo in reducing the Week 6 mean change from baseline in PANSS total score. With Amendment 4, enrollment was changed to approximately 500 participants with removal of the MK-8189 8 mg treatment arm. Participants enrolled before Amendment 4 that have been assigned to 8 mg MK-8189 will remain on 8 mg MK-8189 per protocol.
To evaluate the efficacy and safety of adjunctive pimavanserin compared with adjunctive placebo in the treatment of negative symptoms of schizophrenia
This study will test whether CVL-562 (PF-06412562), a dopamine 1 partial agonist novel compound, affects working memory neural circuits in patients with early episode schizophrenia. The overall aim is to establish neuroimaging biomarkers of the Dopamine Receptor 1/Dopamine Receptor 5 Family (D1R/D5R) target engagement to accelerate development of D1R/D5R agonists in humans to treat cognitive impairments that underlie functional disability in schizophrenia, a key unaddressed clinical and public health concern.
In a randomized controlled design with approximately 26 biweekly sessions over 12 months, the investigators propose to test the effectiveness of an ECHO-based intervention for improving the use of clozapine in people eligible for clozapine. The sessions will include: 1) active dissemination of knowledge and information by an expert "hub" followed by 2) clozapine case presentations and vignettes submitted by the "spokes". This intervention, Clozapine CHAMPION-ECHO (Center for Help and Assistance for Maryland Prescribers- Improving Outcomes Network using Extension for Community Healthcare Outcomes, will be referred to as "CHAMPION" throughout.. To minimize ANC monitoring barriers and maximize recruitment, the investigators will provide Food and Drug Administration (FDA)-cleared ANC point of care (POC) monitoring devices to all study sites, including those in the control condition. The investigators will enroll at least 300 prescribers and additional clinical team members (up to 300) from 60 outpatient mental health clinics (OMHCs) and other treatment sites; approximately half the OHMCs will be randomized to CHAMPION and half randomized to enhanced treatment as usual (ETAU).
This study is a randomised and controlled trial that aims to investigate whether Cognitive Remediation Therapy (CRT) can modulate epigenetic mechanisms by changing methylation levels of BDNF gene in patients with Schizophrenia.
