Filter by:This is a Phase 3, 6-week, randomized, double-blind, placebo-controlled, multicenter, outpatient study in subjects with schizophrenia with an inadequate response to their current atypical antipsychotic treatment. The primary objective of the study is to assess the efficacy of adjunctive KarXT (a fixed dose combination of xanomeline and trospium chloride twice daily [BID]) versus placebo in the treatment of subjects with inadequately controlled symptoms of schizophrenia as measured by the Positive and Negative Syndrome Scale (PANSS) Total Score.
Schizophrenia is a chronic debilitating psychotic disorder. Identifying persons with "clinical high-risk" (CHR) symptoms, which are like those of schizophrenia but less severe, and providing psychiatric care to these individuals has been shown to help prevent psychosis. Current medications used for CHR symptoms, however, are associated with substantial side effect burden. Therefore, practice guidelines do not recommend current medications as routine treatment for the CHR state, and there is a need to identify new treatments for this condition. Research suggests that abnormal brain oxidative stress may contribute to schizophrenia, offering a potential novel treatment target in the CHR state. Oxidative stress is an excess of free radicals, which are generated from normal metabolism and environmental exposures, and can damage cells. Antioxidants in the body normally neutralize free radicals. Antioxidant deficiency could result in excess oxidative stress that damages brain cells, leading to schizophrenia. Recent studies suggest that N-acetylcysteine (NAC), a precursor of the most abundant brain antioxidant, glutathione, may be a safe, well-tolerated treatment for schizophrenia. In light of this, NAC may also reduce symptoms and brain abnormalities in CHR patients.
This study is evaluating the effectiveness of recovery oriented cognitive therapy (CT-R) for patients with schizophrenia/schizoaffective disorder. To evaluate CT-R, the investigators are conducting a randomized controlled trial with patients from community mental health centers. Participants will be randomized to the CT-R condition, in which the participants will receive approximately 9 months of CT-R as an adjunctive treatment to current medical treatment, or to the continued usual care control condition. The primary outcome measure (positive, negative, and general psychopathology symptoms) as well as secondary measures (quality of life, self-esteem, social anhedonia, recovery, dysfunctional attitudes, resilience, internalized stigma, and hopelessness) will be measured at baseline, 4-5 months after the first therapy appointment, approximately 9 months after the first therapy appointment, and approximately 15 months after the baseline appointment.
The negative symptoms and cognitive deficits are common in patients with schizophrenia, and do not respond well to antipsychotics. The effective treatments for negative symptoms and cognitive impairment are still to be explored. rTMS is a safe and non-invasive physical treatment, some studies has been indicated that the high frequency rTMS could increase the excitability of cortex, and has potentials to improve negative symptoms and cognitive function in schizophrenia. In this study, we explore the effects of iTBS on negative symptoms and cognitive function based on identifying the brain network connection of schizophrenia symptoms.
The primary purpose of this randomized, double-blind, placebo-controlled cross-over study is to record and measure 40 Hz-auditory steady-state response (ASSR) in healthy controls (HC) and participants with mild-to-moderate schizophrenia (SZ) to determine if the mean inter-trial coherence (ITC) magnitude derived from the 40 Hz-ASSR is lower in SZ than in HC at baseline.
This 10 week intervention, Specific Cognitive Remediation with Surround (or SCORES), is designed to target processing speed, a cognitive domain related directly to social functioning, which in turn, represents a vulnerability factor for psychosis. This remotely-delivered intervention combining targeted cognitive training exercises and group support was developed to directly impact processing speed, and at the same time, boost motivation and engagement in adolescents at risk for schizophrenia and other psychotic disorders.
Patients affected by schizophrenia often present significant deficits in various aspects of social cognition, such as social perception, recognition of one's own and other people's emotional state and the theory of mind. Recent studies investigated the correlation between social cognition and real-life functioning, reporting that greater social cognition deficits determine worse social and occupational functioning in real-life. Therefore, social cognition deficits represent an important target both in therapeutic and rehabilitative treatment in patients with psychotic conditions, especially in the early phases of the disease. Our research group has implemented a new individualized rehabilitation programme for social cognition: the Social Cognition Individualized Activities Lab, SoCIAL. The pivotal study showed that this programme improves specifically social cognition abilities, even when compared to a standardised and validated rehabilitation programme such as the Social Skills And Neurocognitive Individualized Training (SSANIT). However, the improvement in social cognition did not translate in improvement in real-life functioning. Recently, another key aspect that plays a role in quality of life and real life functioning in people with schizophrenia has emerged, the narrative abilities. Available data confirm that this variable has a strong impact on social functioning and quality of life in patients with schizophrenia. Taking into account the above evidence, our group decided to implement a new version of the social cognitive remediation programme in order to overcome the limitations found during its pivotal study. The new SoCIAL programme is characterized by specific modules for training of social cognition and narrative abilities in patients with schizophrenia. The efficacy of this programme, compared to treatment as usual, in individuals diagnosed with schizophrenia or schizoaffective disorder will be assessed. The generalization of improvement to real-life functioning domains will also be evaluated in completers and in the intent-to-treat sample.
The primary objective of this grant is to develop and evaluate an Artificial Intelligence-based clinical training tool--CBTpro--to support high-quality skills training in CBT for psychosis (CBTp). CBTpro will provide a rapid means of scaling and sustaining high-quality CBTp in routine care settings across the US.
ARCoS is a pilot study evaluating the feasibility and preliminary effects of a method of cognitive remediation by a Rhythmic, Vocal and Embodied Musical Learning for a population of stabilized schizophrenic patients. 20 stabilized schizophrenics patients will participate in the study for 9 months, i) 6 months of Musical learning (24 sessions over the 6 months) ; ii) and 3 months of follow-up post cognitive remediation. Assessments of attention deficits, inhibitory abilities, negative symptoms and anxiety, will carried out at baseline (V1, M0), third month (M3), sixth month (M6) after the start of the intervention and third months after the end of the intervention (M9). The primary endpoint will be the proportion of patients who have attended at least 80% of the musical training sessions over the 6 months (participation in at least 19/24 sessions).
The purpose of this study is to determine the pharmacokinetics (PK), tolerability and safety of brexpiprazole LAI following a single administration in subjects with schizophrenia.
