NCT03810755
Clinical objectives: estimate the common effect of the EfiKroniK physical exercise program for people with a set of Chronic diseases (solid cancers, hematological, schizophrenia and COPD), expressed in terms of functional capacity, quality of life and others results, regarding the standardized intervention of healthy habits 'Prescribe Healthy Living 'PVS. Implementation objectives: describe the adherence, continuity, adequacy and usefulness of EfiKroniK perceived by patients and professionals, with the purpose of designing implementation strategies, which will be evaluated in future trials. Design: clinical trial and implementation, pragmatic and randomized to two groups stratified by pathology, followed for 12 m. Participants: 370 patients diagnosed with solid cancers, hematological cancers, schizophrenia and COPD, in the most advanced stages. Scope: Hospital de Cruces, Basque Country University, Primary Care Research Unit of Bizkaia. Intervention: personalized exercise program for patients, supervised during 3 months by nursing in primary and autonomous care afterwards, with support from community resources. Reference group: PVS program, of proven effectiveness for the promotion of physical activity, diet and smoking cessation. Measurements: main measure of results: functional capacity at 3 months (6-minute test and submaximal running / running tests at foot to determine the speed of lactate thresholds) and quality of life at 6 and 12 months (SF-36 and specific questionnaires by pathology). Secondary variable results: physical and psychic symptomatology, biological markers, physical form and survival. Analysis: The common effect of the exercise will be estimated by comparing both groups by intention to treat, by means of analysis of the covariance of mixed effects for the changes observed at 3, 6 and 12 months adjusted for the baseline and possible confounders. Previously, a possible interaction effect between the pathology group and the effect of the intervention will be ruled out. The cost-effectiveness and cost-utility reasons.
NCT05712928
Schizophrenia is a chronic and severe mental disorder affecting 20 million people throughout the world and is the fourth leading cause of disability in the developed world. Currently, restrictions due to the COVID-19 pandemic, cause greater social withdrawal, reduced access to social support, lack of motivation, under-activity and loneliness for patients with schizophrenia. Given the prevalence of under-activity, interventions such as dance/movement therapy that use movement and dance to support intellectual, emotional, and motor functions of the body, can optimize the functioning of individuals with schizophrenia. There have been urgent calls for research on telehealth interventions to address the mental health needs caused by COVID-19 pandemic. To address this call, this study will test the feasibility and acceptability of a novel, 10-week dance/movement therapy protocol to promote activation in chronic schizophrenia designed for telehealth delivery. This study will be the first to examine the feasibility and preliminary effects of telehealth dance/movement therapy to promote activation in chronic schizophrenia. This study can contribute towards the development of telehealth interventions for treatment and rehabilitation of individuals with chronic schizophrenia.
NCT03919994
The objectives of this study are to describe characteristics, treatment patterns, and outcomes of patients with schizophrenia newly initiated on 1 of 4 FDA-approved atypical Long Acting Injectable (LAI) antipsychotics (ABILIFY MAINTENA®, ARISTADA®, INVEGA SUSTENNA® or RISPERDAL CONSTA®)
NCT02404155
Clozapine (CLZ) is the most effective antipsychotic for treatment-refractory schizophrenia (SZ). Despite the overwhelming evidence of superior efficacy, CLZ is infrequently prescribed in the US, at a considerably lower rate than the estimated prevalence of treatment-resistant SZ, especially for African-Americans (AA). Recent evidence suggests that low Absolute Neutrophil Counts (ANC), either at baseline or during treatment are a significant barrier to CLZ use in AA patients in the US, where guidelines mandate CLZ discontinuation if ANC drops below 1500 cells/mm3. The investigators group has found that discontinuation of CLZ in AA patients is over twice that in European-American (EA) patients (N\~400; 42% vs.19%, P=0.041) and initiation rates are 50% lower. In a Statewide study (N=1875), the investigators reported that discontinuation was more frequently due to neutropenia in the AA sample, though no AA had developed agranulocytosis (8 cases in EA). Benign Ethnic Neutropenia (BEN) in people of African ancestry, including AAs, identifies a group (50% of AA) with low ANCs but no increased risk of agranulocytosis or infection. Low baseline or in-treatment fluctuations requiring CLZ discontinuation under current prescribing guidelines are common in CLZ-treated persons with BEN. In the investigators recent pilot study of N=12 AA patients with BEN, treatment was safely and successfully continued with CLZ despite low baseline ANC (outside current guidelines). Recent evidence implicates a polymorphism in the Duffy Antigen Receptor Chemokine (DARC) gene in the pathophysiology of BEN. In homozygotes (FY-/-) for the DARC null allele, mean within-subject neutrophil counts are reduced, resulting in sporadic ANC \<1500 cells/mm3 in 10-15% of people with the allele. In population studies, the FY-/- genotype is found in 0.01% of EAs, 99.3% of sub-Saharan Africans (SSA), and 68% of AAs. Further, a missense DARC mutation has been reported to interact with the DARC FY-/- in determining low WBC in AAs. Normal patterns of week-to-week fluctuation in ANC levels in individuals of African ancestry with BEN and the DARC null genotype are not known, and no published research has examined variation in ANC in African ancestry CLZ-treated SZ patients with BEN and the DARC null genotype (FY-/-). Such data are also lacking on individuals with BEN without the DARC null genotype. Conducting such research will generate genetic marker and safety data that could be used to expand access to CLZ for AA patients who otherwise are eligible to receive this superior treatment option.
NCT05695144
Despite major advances in the field of psychopharmacology in recent years, the majority of treated schizophrenia patients retain disabling symptoms, most commonly a variety of negative symptoms. Currently, clinical treatment of schizophrenia remains dominated by pharmacological control. The current use of antipsychotic medications is effective in controlling the positive symptoms of schizophrenia, but has little effect on the negative symptoms. Neuroimaging and neurophysiological studies have shown that negative symptoms are associated with abnormal brain activity in the combined right and left dorsolateral prefrontal and temporoparietal joint regions, and that physical therapy techniques can modulate cortical activity. Therefore, this study aims to investigate the efficacy of transcranial direct current stimulation(tDCS) combined with repetitive transcranial magnetic stimulation(rTMS) on negative symptoms in patients with schizophrenia and to explore possible mechanisms. The double-blind randomized placebo-controlled study comparing active tDCS stimulation combined with active rTMS stimulation, active rTMS stimulation combined with sham tDCS stimulation, and active tDCS stimulation combined with sham rTMS stimulation to sham tDCS stimulation combined with sham rTMS stimulation at 4 weeks of treatment and 2 weeks of follow-up in patients with predominantly negative symptoms with schizophrenia was studied for efficacy. In addition to the primary observation of changes in the Negative Symptom Assessment Scale (SANS), secondary outcomes include changes in Positive and Negative symptom scale (PANSS) total and negative total scores, changes in the MATRICS Consensus Cognitive Battery (MCCB), changes in local brain activity (functional magnetic resonance imaging, fMRI), white matter integrity (diffusion tensor imaging, DTI), changes in laboratory examination indices changes and changes in psycho-behavioral and EEG index. This is the first clinical trial combining tDCS with rTMS for the treatment of schizophrenia patients with predominantly negative symptoms. This study will provide solid evidence for the combination of tDCS with rTMS for the treatment of negative symptoms in schizophrenia. This study will also help to further explore the mechanisms of tDCS combined with rTMS for the treatment of negative symptoms in schizophrenia in terms of imaging and behavior.
NCT03187769

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.
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.
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.

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.

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.
