Dose Response Effects of Quillivant XR in Children With ADHD and Autism: A Pilot Study

July 3, 2017 updated by: Mark Stein, Seattle Children's Hospital

Quillivant XR in Children With Attention Deficit/Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD): A Pilot Study

The purpose of this study is to determine whether Quillivant XR is effective in the treatment of ADHD in children with Autism Spectrum Disorder (ASD).

Study Overview

Detailed Description

To evaluate the safety and tolerability of low to moderate dose effects of Quillivant XR (liquid methylphenidate) and to observe changes in ADHD symptoms and functional outcomes in children with ASD and ADHD. The investigators propose to investigate the low to moderate dose range of methylphenidate compared with a very low dose with a gradual dose escalation schedule because children with ASD have been found to be more sensitive to the adverse effects of methylphenidate (especially in medium to high doses) than children without ASD.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
ADHD Rating Scale - IV
Time Frame: once a week for 6 weeks
Measures the severity of Total ADHD symptoms, Inattention and Hyperactivity/Impulsive symptoms. The Inattention and Hyperactivity/Impulsive symptoms can range from 0 to 27 each, with a higher score reflecting more severe ADHD symptoms. The total score is calculated by summing the inattention and Hyperactivity/Impulsive subscales. The total score can range from 0 to 54 with a higher score reflecting more severe ADHD symptoms.
once a week for 6 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Clinical Global Impressions-ADHD - Severity
Time Frame: once a week for 6 weeks
The CGI-S scale summarizes the clinician's impression of the participant's symptom severity and ranges from 1-7 with 1 representing normal (not at all ill) and 7 representing extremely ill.
once a week for 6 weeks
Clinical Global Impression - Improvement (CGI-I)
Time Frame: once a week for 6 weeks
The CGI-I scale summarizes the clinician's impression of the participant's symptom improvement and ranges from 1-7 with 1 representing very much improved and 7 representing very much worse.
once a week for 6 weeks
