A Classroom Study to Assess the Time of Onset of Vyvanse (Lisdexamfetamine Dimesylate) in Pediatric Subjects Aged 6-12 With Attention Deficit/Hyperactivity Disorder (ADHD)

A Phase IIIb, Randomized, Double-Blind, Multi-Center, Placebo- Controlled, Dose-Optimization, Cross-Over, Analog Classroom Study to Assess the Time of Onset of Vyvanse (Lisdexamfetamine Dimesylate) in Pediatric Subjects Aged 6-12 With Attention-Deficit/Hyperactivity Disorder

The primary objective of this study is to assess the time of onset of Vyvanse compared to placebo, in the analog classroom as measured by the Swanson, Kotkin, Agler, M. Flynn and Pelham (SKAMP) deportment scale in children (aged 6-12) diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD).

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Onset of Effect of Vyvanse	The onset of effect will be defined as the first assessment time showing statistical significance between Vyvanse and placebo as measured by the Swanson, Kotkin, Agler, M-Flynn, and Pelham (SKAMP) Deportment scale. The degree of impairment is rated from 0 (normal) to 6 (maximal).	Evaluations were conducted at 1.5, 2.5, 5.0, 7.5, 10.0, 12.0, and 13.0 hours post-dose.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Duration of Effect of Vyvanse	Duration of effect will be defined as the first time point at which there is a non-significant difference between Vyvanse and placebo after a time point at which there is a significant difference between the two treatment groups as measured by SKAMP Deportment Scores. The degree of impairment is rated from 0 (normal) to 6 (maximal).	Evaluations were conducted at 1.5, 2.5, 5.0, 7.5, 10.0, 12.0, and 13.0 hours post-dose.
