Summary of the Proposed Research:

In this project, we will re-analyze existing data of randomized controlled trials with two medications, aripiprazole and risperidone, that are currently approved by the Food and Drug Administration for the treatment of irritability and aggression in individuals with autism spectrum disorder (ASD) that is characterized by impairment in social communication and interaction and restricted interest and repetitive behaviors. Although these medications are widely used for irritability and aggression, there is a lack of data supporting how early we can predict ultimate treatment response to these medications based on early improvement in symptoms. Therefore, we will conduct a re-analysis of raw data for individual participants in each clinical trial. Better understandings of early prediction of treatment response will assist us in deciding whether it is meaningful for us to continue treatment or switch to another treatment to minimize prolonged exposures to these medications that may lead to side effects.
