Brief summary:
The time course of response following one dose of a new methylphenidate hydrochloride extended release capsule is studied in children 6-12 years in a simulated laboratory classroom setting. Biphentin methylphenidate hydrochloride extended release capsule has been formulated for daily dosing to provide treatment of a child with Attention deficit hyperactivity disorder (ADHD) for the substantial day.

Detailed description:
Biphentin methylphenidate hydrochloride (HCl) extended release (ER) capsules is provided in multiple strengths of 10, 15, 20, 30, 40, 50, and 60 mg to be administered once daily. Once daily dosing is intended to provide treatment for the substantial day.

For current analog classroom study each eligible subject will be optimized at 15, 20, 30, or 40 mg in a timeframe of five weekly periods. In the sixth week each subject will be randomized double-blind to receive either active comparator at the optimized dose or placebo comparator treatment. The first classroom session will be held at the end of the week, when efficacy measurements including Swanson, Kotkin, Agler, M-Flynn, Pelham Rating Scale (SKAMP) and Permanent Product Measure of Performance (PERMP) tests will be administered. At the beginning of the following week, the subjects will be crossed-over to the corresponding active comparator or placebo comparator treatment. The second classroom session will be held at the end of the second double-blind week, when the same efficacy measurements will be administered.

Various safety and tolerability, and quality of life assessments will be conducted.

Arms:
arm 1: Open Label Phase: Subjects were dose optimized over a 2 to 4 week period. All subjects began at an initial Methylphenidate hydrochloride extended release capsules dose of 15 mg and were titrated weekly to an optimal dose using strengths of 15, 20, 30, up to the maximum of 40 mg/day.

Double Blind Phase (2-weeks):

Placebo: Capsule without active drug for 1 week Methylphenidate HCl ER Capsule: An optimized dose of Methylphenidate hydrochloride extended release capsules (15, 20, 30, or 40 mg) for 1 week Dosed once daily in the morning arm 2: Open Label Phase: Subjects were dose optimized over a 2 to 4 week period. All subjects began at an initial Methylphenidate hydrochloride extended release capsules dose of 15 mg and were titrated weekly to an optimal dose using strengths of 15, 20, 30, up to the maximum of 40 mg/day.

Double Blind Phase (2-weeks):

Methylphenidate HCl ER Capsule: An optimized dose of Methylphenidate hydrochloride extended release capsules (15, 20, 30, or 40 mg) for 1 week Placebo: Capsule without active drug for 1 week Dosed once daily in the morning
