NCT01104792
The objective of this study is to evaluate the long-term safety, tolerability, and pharmacokinetics of cariprazine in patients with schizophrenia.
NCT01542229
As in the general population, there is no clear standard of care within Veterans Affairs Medical Centers for treating posttraumatic stress disorder (PTSD) among individuals with severe mental illness (SMI). This is a considerable issue because trauma, posttraumatic stress disorder (PTSD), and severe psychiatric comorbidity are particularly common among Veterans and this symptom presentation clearly exacerbates the overall course and severity of mental illness. This study is significant in that it proposes to establish the efficacy of a frontline exposure based intervention for posttraumatic stress disorder (PTSD), Prolonged Exposure, for improving critical clinical, quality of life, and cost outcomes among Veterans with severe mental illness (SMI) enrolled in VA healthcare. Collectively, it is anticipated that these data will establish a much needed clinical course of action for what is considered a vulnerable yet highly underserved patient population.

The two Arms consist of 25 weekly hours of Music Therapy by educated Music Therapists and time compensated Music Listening by unknown Care Staff Members. The Study is a close Cooperation between Aalborg University (The Music Therapy Research Clinic) and Aalborg University Hospital, Psychiatry.
NCT01874756
The primary objectives of this application are to determine if the selective ERβ agonist LY500307, when added to antipsychotic medications, improves negative and/or cognitive symptoms in patients with schizophrenia. The specific hypotheses to be tested are to determine if LY500307 is safe and well tolerated in this population and whether it elicits a sufficient efficacy signal to be advanced for further testing in schizophrenia. A two-stage Phase 1b/Phase 2a adaptive ("drop the inferior dose") experimental design is ongoing that combines three studies (clinical dose optimization, cortical target engagement confirmation and efficacy and safety assessment) into a single clinical trial. Stage 1 was conducted in year 1 and Stage 2 will be conducted in years 2 and 3. The goal of Stage 1 was to identify and advance the highest dose that did not demonstrate a safety signal and had target selectivity as determined by lack of TT suppression. This criteria was fulfilled at both doses, the larger of the two (75 mg/day dose) was advanced to Stage 2. Furthermore, there was no suggestion of ERα receptor activation (i.e., no pattern of TT decreases or feminization AEs) at either dose (25 mg/day and 75 mg/day). A third arm of 150 mg/day was added to Stage 2 for evaluation. Stage 2 results in the following three arms: placebo, 75 mg/day and 150 mg/day. The goals of Stage 2 are to further assess LY500307 doses for safety and target selectivity, confirm cortical target engagement and assess efficacy. Primary Aim 1: To determine if LY500307 demonstrates cortical target engagement as assessed by fMRI/N-back in frontal-parietal regions. Secondary measures of target engagement are fMRI episodic memory, Pseudo-Continuous Arterial Spin Labeling, Mismatch Negativity/evoked response potentials, Auditory Steady State Response, Auditory P300 and Quantitative EEG (QEEG). Primary Aim 2: To determine if LY500307 is superior to placebo for one or more of the primary efficacy endpoints: negative symptoms (Negative Symptom Assessment Scale - 16-item total score), working memory (the composite score for the Letter Number Sequencing and Spatial Span tests) and verbal memory (Hopkins Verbal Learning Test). Primary Aim 3: To determine if LY500307 reduces total testosterone (TT) plasma concentrations, which is indicative of loss of selectivity for ERβ and engagement of ERα, using the following criteria: Decrease in TT plasma concentrations of 50% from baseline in 50% of subjects per arm treated for two consecutive post-randomization values with LY500307 in Stage 1 and Stage 2 of the trial. Primary Aim 4: To assess the safety of LY500307 by determining if there are SAEs, AEs "probably related to study drug," QTc prolongation, TT suppression (50% reduction from baseline) and to evaluate for other safety signals.
NCT04001439
The primary objective will be to evaluate effectiveness, safety and acceptability of FMT on depressive symptoms at 2 months follow-up in SZ patients with resistant MD.
NCT00148590
The purpose of this study is to evaluate the efficacy and safety of a 6 weeks memantine add-on to risperidon treatment for the prevention of cognitive dysfunction and negative symptomatology in patients with acute schizophrenia. Psychopathological changes were assessed with the Positive and Negative Syndrome Scale (PANSS) at baseline and after 2, 4, 6, 12, and 24 weeks. Cognitive function were measured at baseline and week 6, and 24 by the California Verbal Learning Test, Benton Learning Test, Digit Span Forward and Backward Test, Continuous Performance Test, Stroop Test, Trail-Making Test, Verbal Fluency Test, and Wisconsin Card Sorting Test.
NCT00148616
The purpose of this study is to evaluate the efficacy and safety of 24 weeks memantine add-on treatment to risperidone for the treatment of negative symptomatology and cognitive impairment in patients with chronic schizophrenia.
NCT02773108
Prevalence of somatic comorbidities in psychiatric patients hospitalized in Psychiatric hospital or treated ambulatory or in daily hospital. Comparison of prevalence of somatic comorbidities in psychiatric patients population and the general Croatian population.
NCT02398292
The purpose of this study is to determine the feasibility (≥ 50% completion rate) of a 6-week nutrition, movement, and mindfulness program for youth with recent diagnosis of psychosis.
NCT00148083
The specific aim of this study is to determine whether the new, long-acting, form of risperidone, Risperdal Consta, improves the ability of schizophrenia patients to benefit from skills training. The hypothesis guiding this study is that Risperdal Consta, by improving verbal memory, will improve the ability to benefit from skills training interventions among schizophrenia patients. The primary objective of this study is to compare patients on Risperdal Consta to patients on other atypical antipsychotic medications in terms of their ability to benefit from skills training interventions. A secondary objective of this study is to determine whether patients taking Risperdal Consta improve in other areas of cognitive functioning and social functioning.
NCT02535676
The aim of this study is to evaluate the therapeutic efficacy of tDCS (transcranial direct current stimulation) for treatment of negative symptoms in patients with schizophrenia. The proposed design is a clinical trial, randomized, double-blind, placebo-controlled study. Participants will receive ten sessions of active or sham stimulation in five consecutive days. 100 patients will be randomized into two groups (active tDCS vs sham tDCS) and will be assessed after the intervention: 2, 4, 6 and 12 weeks after. As objectives, the investigators expect to see a clinical improvement of negative symptoms through scales PANSS (Positive and Negative Syndrome Scale), Calgary, Auditory verbal hallucinations, SANS (Skills for Assessment of Negative Symptoms), and expect improvement on computerized cognitive tests. Another goal is to see improvement in biological markers related to schizophrenia, plasma and DNA will be stored.
NCT01969500
This 2-arm clinical trial piloted a mobile Self-Management of Schizophrenia (SOS) system that administers interventions targeting persistent symptoms of psychosis, social dysfunction, and medication adherence. Researchers compared an intervention arm using the SOS system and an arm receiving treatment as usual on the outcomes of change in severity of psychotic symptoms and change in social functioning.
NCT00130923
The purpose of this study is to compare the efficacy of oral risperidone (Risperdal) to risperidone long-acting (Consta) in reducing alcohol use in persons diagnosed with schizophrenia or schizoaffective disorder.
NCT03940898
Medications have a poor effect on negative symptoms and cognitive function in schizophrenia. In the past, most of the studies on repetitive transcranial magnetic stimulation intervention in patients with schizophrenia used conventional stimulation sites and patterns, and the intervention effect was still controversial. A few studies have achieved positive results with the new stimulation model (TBS model) and the therapeutic target (cerebellar vermis), but the follow-up period did not exceed 2 weeks, and no similar studies have emerged in China. Therefore, this study hypothesized that the TBS-mode rTMS intervention in the cerebellar vermis can improve the negative symptoms, cognitive function, and depressive symptoms of schizophrenia, and the efficacy can be maintained.
NCT01400477
The investigators hypothesize that sustained-release DMXB-A-SR (3-2,4 dimethoxybenzylidene anabaseine sustained release) will provide clinical improvement in cognition in patients with schizophrenia who are smokers and who are non-smokers. The study drug may also maintain abstinence from cigarette smoking and improve other symptoms in patients with schizophrenia.
NCT03075657
The proposed study has been planned to evaluate the effect of add-on ramelteon on sleep pattern/quality and circadian rhythm disruption in patients with schizophrenia.
NCT03774927
A randomized, double-blind sham-controlled trial of high frequency rTMS treatment for cognitive impairments in 120 chronic schizophrenia patients
NCT03483909
The majority of schizophrenia patients is impaired in hand gesture performance, which contributes to poor functional outcome and poor communication skills. The left inferior frontal gyrus (IFG) and the left inferior parietal lobe (IPL) are key nodes of the gesture network, which is less active in patients with schizophrenia. Here, the investigators test single sessions of rTMS/TBS known to either enhance or inhibit local brain activity for app. 1 hour. The investigators aim to determine, which protocol may improve gesture performance in patients and healthy controls. This is a randomized, double-blind, cross-over, placebo-controlled single-center trial in 20 patients with schizophrenia spectrum disorders and 20 healthy controls. Gesture performance will be tested immediately after each TMS session, which are separated by 48 hours. Results of this study will inform larger interventional trials comparing 2 TMS protocols with repeated administration.
NCT01567124
The use of antipsychotic medications has increased over the past decade. While more recently developed medications are improved with regards to extrapyramidal side effects, the use of atypical antipsychotics has been associated with substantial weight gain and a worsening of metabolic profile. The time course and extent of weight gain differs among antipsychotics, with olanzapine and clozapine being associated with greatest weight gain. Mechanisms underlying a worsening metabolic profile, obesity and obesity-related illnesses are complex, extending beyond sedentary lifestyle, poor diet and genetic predisposition. There is also a growing body of evidence that the sympathetic nervous system (SNS) has a role in the generation of both obesity and obesity-related illness. While the role of the SNS in blood pressure control is readily acknowledged it is less well appreciated that activation of the SNS exerts profound metabolic effects. Although the fact of a causal relation linking antipsychotic drugs and obesity is unequivocally established, the biological mechanisms operating are unclear, and strategies for preventive therapy remain largely unformulated. This study aims to investigate the role of the SNS and its association with the metabolic abnormalities that are frequently observed in patients with schizophrenia following treatment with antipsychotic medications. Additionally, the study will investigate whether treatment with the centrally acting sympatholytic agent moxonidine will modify SNS activity and, hence, favourably influence the downstream metabolic abnormalities seen in antipsychotic treated patients with schizophrenia. Hypothesis 1: Elevated sympathetic nervous system activity underlies the metabolic disturbances observed in patients following antipsychotic therapy. Aim 1: To investigate the role of the sympathetic nervous system and its association with the metabolic abnormalities that are frequently observed in patients with schizophrenia following treatment with antipsychotic medications Hypothesis 2: Central sympathoinhibition with moxonidine will blunt the elevated sympathetic nervous activity and downstream metabolic abnormalities observed in antipsychotic treated patients with schizophrenia. Aim 2: Determine whether treatment with the centrally acting sympatholytic agent moxonidine will modify sympathetic nervous system activity and, hence, favourably influence the downstream metabolic abnormalities seen in antipsychotic treated patients with schizophrenia.
