omega-3 fatty acids for hyperactivity treatment in autism spectrum disorder

Conditions: Autism Spectrum Disorders; Hyperactivity

Summary: the proposed study is an internet-based, randomized, double-blind, placebo-controlled trial which will assess changes in hyperactivity in children ages five through eight with an autism spectrum disorders (asd) and elevated levels of hyperactivity. in order to answer this question, this study will assess changes in hyperactivity as measured by the aberrant behavior checklist (abc) in children with asd and elevated baseline levels of hyperactivity who are randomly assigned to use 1.3 grams of omega-3 fatty acids daily compared to placebo. the overwhelming majority of study procedures, including recruitment, informed consent, assessment of inclusion and exclusion criteria, and collection of baseline and outcome measures will take place over the internet.

families and caregivers of children enrolled in the ian research between the age 5-8 and with an established diagnosis of autism will be invited to participate in the study by e-mail. all of these families have previously given consent to be contacted about research opportunities. families who respond to the e-mail recruitment letter will undergo a brief screening process to determine if the child has any exclusion criteria and to ensure the child is age 5-8, has an autism spectrum disorder, and has elevated baseline levels of hyperactivity. families will undergo an on-line informed consent process including assent of the child. all participants will be given an opportunity to speak with a study team member should they have any questions about the study or the informed consent process. participants will sign the informed consent using an electronic signature, a process that has been used previously in the ian network and approved by the john's hopkins institutional review board (irb). families meeting all eligibility criteria will be randomly assigned and mailed the study medication (omega-3 or placebo) which will be administered to children by the parents twice daily for six weeks. both the study medication and the matching placebo are an orange-flavored pudding that is specifically designed to be palatable for young children. assessment of child hyperactivity, social functioning, and overall disease severity will be measured at baseline, three and six weeks by the parents, who will complete on-line standard questionnaires; abc, social responsiveness scale (srs), clinical global impressions scale (cgi). side effects will be assessed every week by e-mail, and any report of a side effect will immediately be followed-up with telephone contact from the pi. although omega-3 fatty acids are extremely safe in the prescribed doses, the pi or another study physician will still be on call 24-hours-a-day, 7-days-a-week to speak to participants about possible adverse events or new medical problems (all enrolled families are provided with this 24-hour emergency phone contact information). as part of the weekly e-mail reminder, parents will also be asked to log the medication that was provided to their children each day of the previous week to measure medication adherence.
