NCT05646264
This study is a prospective, multicenter, controlled, real world study. Patients will be randomly enrolled into the test group and the control group at a ratio of 1:1 during the screening period. The test group will choose to add Agomepratin on the basis of a second-generation antipsychotic drug (olanzapine, aripiprazole, risperidone, etc., see Annex A), and the control group will either use a second-generation antipsychotic drug (olanzapine, aripiprazole, risperidone, etc.) for 24 consecutive weeks, To explore the efficacy and safety of the second generation antipsychotic drugs combined with agomeratine regimen in the real world for negative symptoms of schizophrenic patients. Group sequential design is used as the method of interim analysis in the research process. If the research purpose is reached in advance, the research can be terminated. The study followed GRACE standards.
NCT03893825
The primary objective of the study is to evaluate the long-term safety and tolerability of TV-46000. The primary safety and tolerability endpoint is the frequency of all adverse events, including serious adverse events. For new participants, the total duration of participant participation in the study is planned to be up to 80 weeks (including a screening period of up to 4 weeks, a 12-week oral conversion/stabilization stage \[Stage 1\], a 56-week double-blind maintenance stage \[Stage 2\], and a follow-up period \[8 weeks\]). For roll-over participants, the total duration of participant participation in the study is planned to be up to 64 weeks (including up to 56 weeks in the maintenance stage \[Stage 2\] and a follow-up period \[8 weeks\]). Participants who started Stage 2 who relapse or meet 1 or more of the withdrawal criteria should be invited to perform the Early Termination visit as soon as possible within 4 weeks of the last injection. Participants who withdraw from the study before completing the 56-week maintenance stage will have follow-up procedures and assessments performed at their follow-up visits. During the follow-up period, participants will be treated according to the investigator's judgment. All participants will be treated with active drug.
NCT00982982
The study aims to examine the combined effects of delta-9-tetrahydrocannabinol (∆-9-THC or THC) and iomazenil on thinking, perception, mood, memory, attention, and electrical activity of the brain (EEG). THC is the active ingredient of marijuana, cannabis, "ganja", or "pot". Iomazenil is a drug that works opposite to drugs like valium. The purpose of this study is to determine whether the administration of iomazenil will alter the effects of THC.
NCT05065489
Electroencephalography (EEG) has been proposed as a neurophysiological biomarker to delineate psychotic disorders. Meanwhile, the increased appetite, which might related to self-control process, has been an increasing concern for the management of psychotic disorders. In this cross-section study, investigators collect the resting state EEG data, self-control related scale, eating behaviour questionnaire and psychotic syndrome related assessement and try to find the connection between those measurers, in order to provide novel understanding on the mechanism of psychotic diseases.
NCT03129360
In order to establish target engagement and identify an effective dose the investigators will conduct a placebo-controlled single-dose parallel group trial of levetiracetam 185 mg and 500 mg in 24 medication-naïve early psychosis (EP) patients, measuring hippocampal activity by pulsed arterial spin labelling (ASL) pre-dose and 2 hours post-dose. The lower dose is calculated to achieve blood levels within the range that were associated with reduced hippocampal activity and improved cognition in patients with mild cognitive impairment; the higher dose is a typical antiepileptic dose. Successful demonstration of target engagement will be defined by an effect size of 0.5 or greater compared to placebo in reduction by levetiracetam of hippocampal blood flow measured by ASL. The optimal dose will be defined by maximal reduction of hippocampal perfusion in the absence of clinically-significant adverse effects. The investigators will also study 8 healthy control subjects to verify that baseline hippocampal blood flow is elevated in the sample of EP subjects.

cTBS is a promising novel intervention, which have strong potentials on moderating disease syndrome, suck as verbal hallucination, 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 cTBS on prevention and treatment for cognitive deficiency, psychotic syndrome and metabolic side-effects in drug-naive first episode individual with schizophrenia.
NCT04714970
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.
NCT00845026
The primary objective of this study was to assess time to discontinuation due to lack of tolerability among patients with schizophrenia receiving LY2140023, given orally twice daily for 24 weeks, versus those on atypical antipsychotic standard-of-care (SOC) treatment. Lack of tolerability was defined as discontinuation due to adverse events (AEs). Patients who completed the active treatment phase were eligible to continue to an optional 28 weeks of treatment extension phase. This extension phase assessed key safety and efficacy measures.
NCT05601063
Cross-sectional observational study of the relationship between speech patterns and psychiatric symptoms and disorders.
NCT04094207
The aim of this study to evaluate the efficacy and safety of pentoxifylline, the novel phosphodiesterase inhibitor, as an adjunctive to risperidone in alleviating the negative symptoms of schizophrenia.
NCT04284813
The purpose of this study is to develop and evaluate an intervention that adapts Community Reinforcement and Family Training (CRAFT) for families experiencing first episode psychosis and substance use delivered via telemedicine (video conferencing). The intervention aims to improve treatment engagement and reduce distress, and it will be delivered via telemedicine (CRAFT-FT). To assess feasibility of the intervention, family members will complete the sessions and provide feedback to refine the treatment manual. Data on client relatives with psychosis will be collected for preliminary assessment purposes. Client relatives will not complete the research study intervention.
NCT02149823
Social cognition impairment is critical to the pathology and morbidity of a number of psychiatric disorders, including the schizophrenia spectrum, the autism spectrum and the personality disorders, thus representing a dimension consistent with RDoC. As such, this study aims to a) further characterize the unique deficits in social cognition (recognition and interpretation of social cues and representation of thoughts, intentions, and feelings of others) across disorders, including the schizophrenia spectrum (which includes schizophrenia, SCZ, schizoaffective disorder, SAD, bipolar disorder, BD, and schizotypal personality disorder, SPD), the autism spectrum disorders (ASD), and borderline personality disorder (BPD) compared to healthy controls (HC); b) assess the effect of intranasal oxytocin (OXT) as a regulator and novel treatment of social cognition impairment in these disorders; and c) enhance our understanding of the specificity and exact mechanisms of impairment to inform the accurate dosing of OXT required to modulate social cognition in these disorders and identify a model of optimum social cognitive function. Addressing these questions will further catalyze research into a model of optimum social cognitive activity, and accelerate industry development of agents suited to routine clinical administration.
NCT05282329
The aim of this study is to evaluate the feasibility and efficacy of transcranial alternating current stimulation (tACS) as an add-on treatment for auditory hallucinations in refractory schizophrenia. Meanwhile, we aim to evaluate the effect of tACS on cognitive function of schizophrenia patients. we hypothesize tACS would improve refractory auditory hallucination symptoms in schizophrenia by regulating the gamma frequency band of temporal lobe。
NCT01555697
Cognitive training is moderately effective at reducing symptoms and improving life function in schizophrenia patients. The present application develops a strategy for increasing the effectiveness of cognitive training through the use of pro-cognitive medications. Specific biomarkers will be studied that identify patients most sensitive to these pro-cognitive medications, to test the feasibility of using these biomarkers in a large clinical trial of medication-enhanced cognitive training in schizophrenia.
NCT02006628
A study to compare the change in symptom severity in participants with schizophrenia or related psychotic disorder when treated with GWP42003 or placebo in conjunction with existing anti-psychotic therapy over a period of six weeks.
NCT01992393
For this project we propose to refine the psychosocial intervention developed in phase one, based on input from key stakeholders, and to test the feasibility, acceptability and preliminary efficacy of the intervention. The proposed project addresses unmet public health needs for a historically hard-to-reach group of individuals with epilepsy and comorbid serious mental illnesses, and as the intervention is an adjunct to care that individuals with serious mental illness are already receiving, and uses staff already likely to be present in a care system, it is ideally suited for "real-world" implementation in people with epilepsy and serious mental illness (E-SMI). The purpose of this study is to try and engage individuals with E-SMI to actively participate in illness self-management and treatment adherence that are crucial in minimizing the morbidity and mortality associated with both chronic mental disorders and chronic neurological conditions.
NCT04173572
Purpose: 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.
