Guanfacine for the Treatment of Hyperactivity in Pervasive Developmental Disorder
Guanfacine for the Treatment of Hyperactivity in Pervasive Developmental Disorder

The purpose of this study is to determine whether guanfacine (trade name Intuniv) by itself or in combination with methylphenidate (also known as Ritalin) is helpful for treating hyperactivity in children and adolescents with a Pervasive Developmental Disorders (PDDs).

Pervasive Developmental Disorders (PDDs) are a group of conditions that includes Autistic Disorder, Asperger's disorder and so called Pervasive Developmental Disorder - Not Otherwise Specified. Children with PDD show delays in speech and language and reduced social interaction. Some children with PDD have also have problems with overactivity, impulsiveness and distractability. These behaviors are seen in children with Attention Deficit Hyperactivity Disorder (ADHD). Extended release guanfacine (Intuniv) is FDA-approved for the treatment of children with ADHD. The purpose of this study is to evaluate whether Intuniv is an effective treatment for ADHD symptoms in children with PDD.

This study has four parts: an 8-week double-blind trial, an 8-week blinded extension phase (for positive responders only), an 8-week open-label trial, and a 4-week add-on study. Following confirmation of eligibility, participants will be randomly assigned to receive either guanfacine or placebo in the 8-week double-blind trial. Children who show improvement after 8 weeks of treatment will continue on their assigned treatment for an additional 8 weeks (blinded extension phase). Children who show partial improvement with guanfacine will be offered 4 weeks of treatment with guanfacine plus methylphenidate (add-on study). Children who show no improvement on placebo will be offered 8 weeks of treatment with guanfacine (open-label trial). Children who show no improvement on guanfacine will exit the study.

Side effects and treatment response will be assessed at regularly scheduled visits.
