Pharmacokinetic Pharmacodynamic Studies of Methylphenidate Extended Release Products in Pediatric Attention Deficit Hyperactivity Disorder

The purpose of this study is to evaluate the association between blood drug levels and the
corresponding scores of commonly used behavioral instruments based upon data collected
following administration of three different methylphenidate hydrochloride extended-release
drug products in children with ADHD.

This is a randomized, double-blind, 4-treatment and 4-period crossover study conducted in a
school laboratory environment to evaluate the hour-by-hour behavioral instrument scores and
hour-by-hour PK of 3 different extended-release MPH formulations as well as placebo in
children with ADHD. The complete study consists of three periods: Screening, Dose Titration
and Double-Blind Crossover in a Laboratory Classroom.

The double-blind phase will consist of four periods (or four weeks): each week will consist
of blinded administration with one of the three active methylphenidate hydrochloride
treatments or placebo from Sunday through Saturday. On the last day of each period
(Saturday), study participants will be evaluated in a laboratory classroom setting. On
Saturdays, the blinded doses of each study drug will be administered at the school site by
study staff on the morning of the test laboratory classroom day. On the other days, the
medication will be taken in the morning at home.
