Brief summary

This study is a single site, double-blind, randomized, placebo-controlled parallel group design. this study is designed to directly examine the efficacy of a single daily dose of atomoxetine taken in the morning in alleviating sleep initiation insomnia in children with ADHD. Primary outcome measures are sleep parameters, specifically mean sleep onset latency (time of onset to persistent sleep), as measured by actigraphy/sleep diary, and parent and child-reported evening settling difficulties, as measured on the evening subscale items of the parent and child versions of the DPREMB-R. Secondary outcome measures include: additional actigraphic sleep parameters (night wakings, sleep duration, and sleep efficiency), daytime sleepiness (Pediatric Daytime Sleepiness Scale, sleepiness visual analogue scale (VAS), and morning behaviors on the DPREMB-R); ADHD symptom improvement (ADHD-RS, parent version; provider-completed CGI); a neurocognitive measure of attention and impulsivity (CPT); executive functions (Brown ADD Scale for Children) and functional outcomes/quality of life (CHQ).

Interventions

DRUGatomoxetine

Patients will then be randomized (at Visit 2) to receive either atomoxetine or placebo for 4 weeks (Treatment Period); study drug will be titrated individually according to tolerability and efficacy (measured by ADHD-RS and CGI-I) completed at Visits 3, 4, 5, and 6) at 7-10 day intervals to a maximum dose of 1.8 mg/kg.

Subjects are children aged 6 through 17 years with DSM-IV criteria-defined ADHD and sleep initiation insomnia.

Exclusion criteria

All subjects will be screened for primary sleep disorders with survey questionnaires (Children's Sleep Habits Questionnaire, CSHQ (12) and Restless Sleep Questionnaire) (Visit 1); subjects scoring above a pre-defined threshold for OSA and/or RLS/PLMD symptoms will be excluded from the study.
