Efficacy, Safety and Tolerability of Zolpidem in the Treatment of Children Aged 6 to 17 Years With ADHD-Associated Insomnia. A Multicentre, Randomized, Double-Blind, Placebo-Controlled Study

There has been an increased interest in the association between ADHD and sleep disorders over the past years. A high incidence of sleep disturbance, ranging from 10% to 70%, has been identified in ADHD children regardless of whether or not they are receiving stimulant therapy. This study will assess the safety and efficacy of zolpidem in children with ADHD associated insomnia.

Detailed Description

The study is being conducted in the United States. It consists of 3 segments:

  • Segment A: 2 to 21 day screening period
  • Segment B: 8-week double-blind treatment period
  • Segment C: 1-week follow-up period

Subjects will have a polysomnography in a sleep lab two times during the study (at baseline and between visit 4-5) and also be required to wear an actigraphy monitoring tool. There will be several questionnaires completed throughout the study: CGI-child, CGI-parent/legal guardian, ADHD Rating Scale-IV, and the Pediatric Daytime Sleepiness Scale.
