Filter by:The proposed pilot study will compare minocycline augmentation with clozapine in individuals with high vs low inflammation as measured by CRP. Investigators hypothesize that minocycline will be well tolerated and will result in an improvement in the symptoms of schizophrenia, cognition, as well as improve the quality of life for patients preferentially in patients with high CRPs. Investigators plan to use a variety of different scales to measure improvement in the varying symptoms of schizophrenia as well as cognitive function, which will be administered to patients at three week intervals for a total study time of twelve weeks. Investigators hypothesize that minocycline could prove to be an effective, well tolerated, and inexpensive medication for treatment resistant patients with schizophrenia whom have particular difficulties with social interactions, obtaining and maintaining employment, and overall quality of life. Furthermore, investigators hypothesize that the data obtained in this study will contribute to the ongoing exploration of the role of inflammation in the brain of patients with schizophrenia and help understand and target the role of various inflammatory markers in the pathophysiology and treatment of treatment resistant schizophrenia.
This study is to assess the bioavailability of LY03004 compared to Risperdal Consta as well as the evaluate the safety and tolerability and preliminary efficacy of LY03004 with repeat injections
The goal of this project, which has not changed, is to improve the health and fitness of persons with serious mental illness (SMI) using an innovative model: In SHAPE Lifestyles. Participants are randomly assigned to the In SHAPE program or Health Club Membership and Education only. The three specific aims of this study are to: 1. To compare the treatment groups with respect to improvement in physical fitness outcomes, including: (a) health behaviors (engagement in exercise and diet changes); and (b) indicators of physical fitness. 2. To compare the treatment groups with respect to improvements in mental health outcomes, including negative symptoms, depression, and self-efficacy. 3. To explore differences in the treatment groups with respect to psychosocial functioning, health status, and acute service use, and the effects of selected demographic, clinical, and health behavior variables on primary outcomes.
This is a prospective study using a concierge model of customized adherence enhancement and long-acting injectable antipsychotic (CAL-Concierge) in 30 individuals with schizophrenia or schizoaffective disorder at risk for treatment non-adherence and for homelessness. Like the CAE-L approach, CAL-Concierge is expected to improve health outcomes among the most vulnerable of populations with schizophrenia but even more importantly, will demonstrate that it can be used to improve the efficiency and quality of care in typical practice settings.
Paliperidone ER is a new psychotropic medication for schizophrenia treatment. The studies of 6-week acute treatment and 52-week maintenance treatment showed positive results in patients with schizophrenia and its clinical improvement may start at Day 4. Some second-generation antipsychotics have been found that using the first 2 weeks' treatment results to predict the fourth or sixth week's treatment response is acceptable. The primary aim of this study is to investigate: 1. . whether the early prediction model used in other atypicals could also be applied in paliperidone ER. 2. . The changes of metabolic parameters and pharmacokinetics after paliperidone ER treatment in this study
The aim of the this study is to evaluate the effectiveness of methotrexate added to treatment as usual on positive and negative symptoms, cognitive and social functioning and quality of life of patients suffering from schizophrenia.
Schizophrenia is marked by problems in attention, memory and problem solving. These deficits predict long-term functional outcome such as the ability to live independently and maintain employment, but they are not ameliorated by currently available medications. Cognitive training improves these functions to some degree, but this approach is time- and resource-intensive. The current project aims at enhancing and accelerating the benefits that people with schizophrenia derive from cognitive training by administering nicotine during some of the training sessions. This would provide the proof of principle for a type of treatment intervention to improve cognitive symptoms of schizophrenia. The current project aims at determining whether the intermittent presence of nicotine during cognitive training exercises in people with schizophrenia will shorten the training period necessary to induce significant and clinically relevant improvement and enhance the improvement seen after a training period of specified length. Hypothesis 1a: Nicotine administration during training will increase the size of all measured effects of the training intervention, and will accelerate the time course of performance enhancement on the MCCB and training exercise progression parameters. Hypothesis 1b: The larger training effects in the Nicotine Group will persist beyond the end of the intervention. Hypothesis 2a: Within-session progress on the training exercises will be larger in the presence of nicotine than in the presence of placebo. Hypothesis 2b: These acute nicotine-induced performance elevations will persist beyond the presence of nicotine through subsequent non-drug training sessions, giving evidence of an acute facilitation of learning processes.
The purpose of this study is to characterize the pharmacokinetics (PK) of LY03004 following an escalating single intramuscular injection at 12.5, 25, 37.5, or 50 mg; and to evaluate the safety and tolerability and preliminary efficacy of LY03004 following intramuscular injection.
Randomized, double-blind clinical trial of tocilizumab vs. placebo as add-on treatment for residual positive, negative, and cognitive symptoms in schizophrenia. The primary study hypothesis is that individuals receiving tocilizumab will show greater improvements in their PANSS total scores than those taking placebo.
The early stages of schizophrenia are associated with significant decreases in social and intellectual abilities, with more declines in chronic disease. Studies have identified relationships between duration of untreated psychosis (the duration between the onset of positive symptoms and treatment) and worse long term outcomes. However, the neurobiology of this phenomenon and its implications for response to antipsychotic medications remain poorly understood. Glutamatergic excess altering brain connectivity might provide an explanation for why those with longer duration of untreated psychosis have worse clinical outcomes. The investigators propose to use neuroimaging to study 67 first episode psychosis subjects before and after sixteen weeks of treatment with risperidone, a common antipsychotic. We will measure (1) glutamate and (2) structural and functional brain connectivity and test the hypotheses that glutamatergic abnormalities are present in first episode patients and that longer duration of untreated psychosis is associated with greater connectivity abnormalities that set the stage for poor response to treatment. 67 demographic-matched controls will also be recruited as a comparison group - healthy controls will not receive antipsychotic medication. The investigator's previous studies have made progress in the understanding of abnormalities in the glutamate system and brain connectivity in unmedicated patients with schizophrenia and modulation of these by antipsychotic medication. Two indices of glutamatergic dysfunction have been identified. While antipsychotic medications appear to modulate glutamate, the disturbance in the relationship between metabolites is not restored with treatment. In addition, the investigators found that both structural and functional connectivity abnormalities in unmedicated patients with schizophrenia predict patients' response to treatment. To the investigator's knowledge, no other group has performed a study that uses a combination of complementary neuroimaging techniques that will allow generating a broad characterization of glutamatergic function and brain connectivity in first episode psychosis and change with treatment. The results of the proposed studies could suggest a mechanism by which the duration of untreated psychosis is associated with poor treatment response which might lead to new interventions to target the illness.
