Primary Outcome Measures:
  • Latency to Persistent Sleep (LPS) as measured by polysomnography (PSG) [ Time Frame: performed at Baseline (Visit 2), after the subject has met all other inclusion/exclusion criteria, and at Week 7 or Early Termination ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • PSG sleep parameters: Wake time After Sleep Onset (WASO), Number of Awakenings After Sleep Onset (NAASO), and Total Sleep Time (TST) [ Time Frame: within four days prior to Baseline (Visit 2), after the subject has met all other inclusion/exclusion criteria and Week 7 or Early Termination (Visit 9) ] [ Designated as safety issue: No ]
  • Actigraphic measures of sleep characteristics (LPS, TST) [ Time Frame: during the week immediately preceding the following study visits: Visit 2 (Baseline), Visit 5 (Week 3), and Visit 9 (Week 7) ] [ Designated as safety issue: No ]
  • Pittsburgh Sleep Quality Index and Child Sleep Habits Questionnaire item scores [ Time Frame: performed at Visits 2 through 9 ] [ Designated as safety issue: No ]
  • Clinical Global Impression (CGI) Severity and Global Improvement item scores [ Time Frame: each weekly visit ] [ Designated as safety issue: No ]
  • Conner's Parent Rating Scale - Revised (S) completed by parent/caregiver and Investigator-rated ADHD-RS-IV item scores [ Time Frame: Visits 2 through 9 ] [ Designated as safety issue: No ]

Detailed Description:

Treatment with psychostimulants has been associated with sleep disturbances, including both sleep onset and maintenance problems, in children with ADHD. This analysis evaluated the effect of lisdexamfetamine dimesylate (LDX) on sleep in children with ADHD.

This single center, double-blind, placebo-controlled, parallel-group trial enrolled children aged 6-12 years with a DSM-IV-TR diagnosis of ADHD. The study included a screening period, 1-week washout, 3-week open-label LDX dose optimization phase, and a 4-week double-blind treatment phase in which subjects were randomized to placebo or active LDX treatment at 30, 50, or 70 mg/d. Polysomnograph and actigraph measures as well as assessments of subjective sleep parameters were performed in all subjects prior to treatment and reassessed after treatment with either LDX or placebo.
