简要总结
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.
详细描述
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.

结局指标
主要结局
Comparison Following Treatment Between Drug and Placebo Using Evaluation by SKAMP Combined, Attention, and Deportment Scales
时间窗: Average over all post-dose time points (1.0, 2.0, 3.0, 4.5, 6.0, 7.5, 9.0, 10.5, and 12 hours)
Comparison of Swanson, Kotkin, Alger, M-Flynn and Pelham (SKAMP) Combined, Attention, and Deportment Scales following drug dose versus placebo. The SKAMP scale is a validated rating scale that assesses behavioral symptoms of ADHD in a classroom setting using a 7-point impairment scale (0 = none through 6 = maximal impairment). The SKAMP total score comprises 13 items, with individual total scores ranging from 0 to 78 (lower scores mean better outcome). The SKAMP-D subscale evaluates deportment, including interacting with other children, interacting with adults, remaining quiet according to classroom rules, and staying seated according to classroom rules. The SKAMP-A subscale is a measure of attention and evaluates getting started on assignments, sticking with tasks, attending to an activity, and making activity transitions. The SKAMP quality of work subscale includes 3 items: completing assigned work, performing work accurately, and being careful and neat while writing or drawing.
