About the study

This interventional multicenter dose-optimization Phase IV PASS conducted in Europe and the USA evaluates the comparative long-term safety and efficacy of SPD503 in children and adolescents aged 6 to 17 years diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD) for whom stimulants are not suitable, not tolerated, or shown to be ineffective. The study will be conducted in two parts: Study Part A (randomized, double-blinded, parallel-group, placebo- and active comparator-controlled, 3-treatment arm safety and efficacy evaluation of SPD503) and Study Part B (open label SPD503 treatment).

Who can take part?

You may be eligible to participate in the study if you meet the following criteria:
