Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Methylphenidate HCl ER tablets 1
During the open-label optimization phase, one of the methylphenidate hydrochloride extended-release products will be titrated at weekly intervals of 18mg increments until an optimal dose is achieved or a maximum of 72mg per day is reached. During the double-blind phase, participants will receive blinded treatment each week. The dose of each methylphenidate hydrochloride extended-release product will be determined by the optimized dose during the open-label optimization phase

Placebo
During the double-blind period, in one of the 4 study weeks, the study participant will take a blinded placebo instead of one of the the 3 active comparators.
Placebo
Methylphenidate HCl ER tablets 2
During the open-label optimization phase, one of the methylphenidate hydrochloride extended-release products will be titrated at weekly intervals of 18mg increments until an optimal dose is achieved or a maximum of 72mg per day is reached. During the double-blind phase, participants will receive blinded treatment each week. The dose of each methylphenidate hydrochloride extended-release product will be determined by the optimized dose during the open-label optimization phase
