Best Event Schizophrenia Trial--A Randomized Double-Blind Trial of Aripiprazole and Risperidone in Schizophrenia — BEST  

Schizophrenia Clinical Trial

Official title:
A Randomized Double-blind Trial of Aripiprazole and Risperidone in Schizophrenia: An Evaluation of Neuroimaging, Neuropsychological, and Pharmacogenomic Markers of Differential Treatment Response

Clinical Trial Summary

This study is being conducted to find a way to predict how individual schizophrenic patients will respond if they are treated with different types of antipsychotic drugs. This could help doctors prescribe the medication that will work best for each individual.

Clinical Trial Description

The primary objective of the proposed research project is to identify a practical method of predicting differential antipsychotic drug treatment response in patients with schizophrenia. In particular, we will examine differential response to two antipsychotic drugs, aripiprazole and risperidone, that have contrasting pharmacologic activity at D2-type dopamine receptors, i.e., partial agonism vs. antagonism, respectively. A number of candidate predictors will be examined, including neuroimaging parameters (regional neuroanatomical and metabolic variations, fallypride binding to D2-like receptors), neuropsychological testing, clinical features, laboratory measures, and genetic studies.

Secondary objectives include: (1) extension of our previous efforts to characterize abnormalities in cortico-striato-thalamic circuits in unmedicated schizophrenics using PET and MR imaging; and, (2) examination of the role of omega-3 fatty acid activity in schizophrenics as a predictor of dopaminergic activity. ;
