Brief Summary:
The specific aim of this protocol is to compare Clozapine treatment vs Non-Clozapine antipsychotic treatment in a population of treatment-refractory individuals with schizophrenia Specifically it is to test if Clozapine leads to a decrease in levels of inflammatory markers namely interleukin-6 but with an exploratory view of other markers Clozapine has superior efficacy and is the only medication approved for treatment-refractory schizophrenia in addition to decreasing the risk of suicidal behavior as well It is unclear why Clozapine has increased efficacy from a mechanistic viewpoint We will look at the role of inflammatory markers and assess them 1x along with rating scales for psychosis and suicidality the other entities which Clozapine has been shown to improve
Detailed Description:
This study is designed to investigate if treatment with the antipsychotic Clozapine is associated with changes in various immune and inflammatory biomarkers when compared to treatment with non-Clozapine antipsychotic treatments Clozapine is a uniquely efficacious treatment of psychotic disorders the only effective agent in approximately 30-40 of individuals with treatment refractory symptoms Clozapine unlike other antipsychotic drugs often precipitates a unique multi-systemic inflammatory response most widely recognized in the cardiovascular system but also likely the central nervous system CNS which is tied into its unique side effect profile but might also account for its increased efficacy Schizophrenia spectrum disorders affect about 1 of the population with around 30-40 of those diagnosed with symptoms refractory to standard non-Clozapine antipsychotic treatment We will measure various inflammatory markers 1x for patients who are stable outpatients Participants will be patients with treatment-resistant schizophrenia on clozapine treatment for at least 6 months referred from OSUs outpatient clinic with a comparator group also referred from Ohio State University having shown treatment resistant symptoms but with providerpatient electing not to use clozapine for clinically relevant reasons and have been on antipsychotic medication for at least 6 months The study includes 1 visit including symptom rating scale assessments and laboratory draw for collection of serum samples and the visit also having more diagnostic assessments to assure proper enrollment If the study results are positive meaning there is a difference between the two groups it would help elucidate the potential mechanisms by which Clozapine works and demonstrates increased efficacy for those with treatment-refractory schizophrenia a severely debilitating life long illness with marked disability This would also allow for further studies to explore this mechanism and the role of inflammation and the immune system as well
