Autism Clinical Trial - Treatment of Children With Autism Spectrum

Status Withdrawn

Clinical Trial Summary

The purpose of this study is to determine if treatment of epileptiform abnormalities in children with autism spectrum disorder will improve any behaviors in these children. The investigators will study a number of different behavioral outcomes including behaviors related to attention, social communication, repetitive behaviors, maladaptive behaviors, language, motor and sensory, and sleep. The investigators will use an anticonvulsant medication called valproic acid (in the form of sodium divalproex).

Clinical Trial Description

Epilepsy and epileptiform EEG abnormalities are common co-morbidities in Autism Spectrum Disorders (ASD) that can be considered important biomarkers of cortical dysfunction in these disorders. They may represent a measure of the excitatory-inhibitory imbalance posited to be involved in the pathogenesis of the disorder. Treatment of epilepsy is always indicated, but treatment of isolated epileptiform EEG (i.e. in the absence of clinical seizures) is frankly controversial. Since data suggest that these epileptiform discharges are associated with deficits in attention, language and behavior, the investigators believe that they may represent an important and novel treatment target in this population. The proposed study brings together a group of investigators long interested in this problem in order to investigate the efficacy of using an anticonvulsant medication with spike suppression capabilities (VPA in the form of divalproex sodium) to treat children with ASD and isolated epileptiform EEGs. Recruiting from 3 large autism centers (Boston Children's Hospital (BCH) and Vanderbilt University (VU) and University of Louisville (U of L)) with very large pediatric epilepsy units, the investigators propose a 26 week randomized placebo controlled cross over study of VPA in 4-8 year old children with ASD with frequent epileptiform EEG discharges. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
