Outcome Measures

Primary Outcomes (1)

  • To assess the duration of efficacy of SPD465 compared to placebo and immediate release amphetamine formulation in adults with ADHD using the Permanent Product Measure of Performance (PERMP) math test

    -0.5, 2, 4, 8, 12, 14 and 18 hours post-dose

Secondary Outcomes (4)
