Filter by:This is a Phase 2, randomized, double-blinded, placebo-controlled, inpatient study to examine the efficacy, safety, and tolerability profile of KarXT in adult subjects diagnosed with DSM-5 schizophrenia who are in an acute exacerbation phase. The primary objective of the study is to assess the efficacy of KarXT (a fixed combination of xanomeline and trospium chloride) (xanomeline 125 mg/trospium 30 mg twice daily [BID]) versus placebo in reducing Positive and Negative Syndrome Scale (PANSS) total scores in adult inpatients with a Diagnostic and Statistical Manual-Fifth Edition (DSM-5) diagnosis of schizophrenia. The secondary objectives of the study are to assess overall safety and tolerability of KarXT in adult inpatients with a DSM-5 diagnosis of schizophrenia.
Cognitive Remediation (CR) involving restorative and strategy-based methods has been previously validated in a pilot study for late life schizophrenia (LLS), where CR demonstrated a moderate effect on overall cognition. This study proposes to study the efficacy of CR in a larger cohort of participants with LLS and to assess the interaction of medication management with CR on cognitive outcomes. Eligible participants will receive CR during 12 weeks. CR consists of a series of computerized exercises targeting various cognitive functions, such as memory, attention and processing speed. It will be administered during facilitated group sessions consisting of 4-6 people. The study will recruit 40 participants with the aim to enroll 30 LLS participants age 55 or older who will undergo the CR intervention for two, 2-hour weekly classes over 12 weeks (24 classes in total). There will be baseline assessments (clinical and NP) prior to enrollment in the classes. In order to assess whether there has been a change in cognition, and some of the assessments will be repeated after the 12-week intervention.
This study aims to evaluate the acute effects of nimodipine on cognitive performance in patients with schizophrenia using a battery of cognitive assessments.The subjects will also complete a 30-minute structural and functional MRI scan, with the goal of linking brain activity with working memory performance. Investigators predict that the performance increase induced by nimodipine will be greater in subjects who carry the A allele for the Calcium Voltage-Gated Channel Subunit Alpha1 C (CACNA1C) risk single nucleotide polymorphism (SNP) (rs1006737) in comparison to the response of G carriers.
This is a phase 1, double-blind, placebo-controlled, 3 period cross-over study to evaluate CVN058 target engagement by measuring auditory evoked potential mismatch negativity (MMN) downstream to 5-hydroxytryptamine receptor 3 (5-HT3) as a pharmacodynamic (PD) marker.
This study applied a randomized parallel case-controlled design. The study purpose was to evaluate the effects of progressive muscle relaxation on anxiety, psychiatric symptoms and quality of life among patients with chronic schizophrenia compared with an active control.
The purpose of this study is to investigate the mean number of schizophrenia-related hospital admissions, in adult participants with schizophrenia, occurred during 12 months before and 12 months after initiation of Paliperidone Palmitate 1-month formulation treatment.
Importance: The problems of side effects of metabolic disturbances in schizophrenic patients have been of worldwide concern for some time. Patients with dyslipidemia have an increased risk of cardiovascular diseases. A Chinese herb, Hawthorn, is widely used for the treatment of dyslipidemia. Objective: Therefore, this study aimed to investigate the effect of Hawthorn on lipid profile levels in schizophrenic patients treated with antipsychotics. Design, Setting, and Participants: A longitudinal case-control study was used in a general hospital in Taiwan. A total of 59 schizophrenics treated with antipsychotics, and 76 healthy adult subjects, who were all hospital workers, were enrolled in this study. Main outcomes and measures: All participants received Hawthorn at a dose of 3 gm/day for six months.
The purpose of this study was to investigate the effects of oxytocin on negative symptoms and social cognitive task performance in schizophrenia. The investigators conducted a randomized, placebo-controlled trial testing the effects of twice daily intranasal oxytocin treatment for 14 days on psychotic symptoms and social cognition in patients with schizophrenia. The investigators hypothesize that PANSS scores will decline significantly and several social cognition measures will improved significantly or nearly significantly in oxytocin but not placebo recipients.
Survey experiment to estimate drivers of mental illness stigma
In this study, investigators designed a double-blind randomized trial to compare the efficacy and safety between sodium valproate, amisulpride and MECT combination therapy in clozapine-treated refractory schizophrenia (CTRS).
