Autism clinical trials at UC Irvine

This study is a pragmatic clinical trial examining the comparative effectiveness of two stimulant medications (methylphenidate and amphetamine) in the treatment of ADHD in children and adolescents with autism. Using a sequential, multiple assignment randomization trial (SMART) design the study will not only assess these two medications but also the role of an increasingly popular class of ADHD medication, the alpha-2 agonists. Findings from this study will help improve clinicians' approach to medication selection and reduce the repeated trials of multiple medications that are current standard care.

This study involves sample collection to identify biomarkers relating to Autism Spectrum Disorder(ASD) in the saliva of children who are between the ages of 18 months to 6 years and 11 months. Participants will at each timepoint have a non-invasive saliva swab collected and complete a brief demographic and medical history questionnaire as well. Children in the pediatric/provider setting who will receive a referral for an ASD diagnosis because they were determined to have a suspicion of developing ASD will be enrolled in the study. Children will also be enrolled in the specialist evaluation setting where they will receive a DSM-5 diagnosis. A subset of both enrollment cohorts will also be followed up with at a third time point in which their diagnosis will be confirmed, and information about any ongoing treatment will be gathered.
