Phase 4, Open Label, Multicentre, 2 Year Safety Study of Lisdexamfetamine Dimesylate in Children/Adolescents With ADHD
A Phase 4, Open-label, Multicentre, 2year Safety Study of Lisdexamfetamine Dimesylate in Children and Adolescents Aged 6-17 Years With Attention-Deficit/Hyperactivity Disorder (ADHD)

The purpose of this study is to evaluate the long-term effects of SPD489 in children and adolescents over a 2-year treatment period.

While SPD 489 clinical program has studied the efficacy, safety and tolerability of SPD489 in treating core symptoms of ADHD in children and adolescents aged 6-17 and adults aged 18-55 years, the majority of the controlled studies have been of short duration (up to 8 weeks). A number of long-term studies have been undertaken and these have confirmed the safety and ongoing efficacy in this patient population.
