Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

There are very few treatments that are effective in reducing severe behavioral problems associated with autism. These behaviors include aggressive and self-harm behaviors, frequent repetitive behaviors and severe hyperactivity. This study is being conducted to determine whether cannabidiol can reduce any or all of these problem behaviors.
