Detailed Description

The hypothesis is that CONCERTA (methylphenidate HCl) is safe and effective in improving academic performance and behavior in children with ADHD when compared to placebo as demonstrated using specified study measures. This is a double-blind (neither participant nor investigator knows the name of the assigned study drug), randomized (study drug assigned by chance), placebo-controlled, crossover study evaluating the academic, behavioral and cognitive effects of CONCERTA (methylphenidate HCl) on older children with ADHD This means that all eligible children will receive treatment with methylphenidate HCl throughout the study (the titration and assessment periods) and inactive pill (placebo) on 1 of the 2 laboratory classroom days. On the other laboratory classroom day they will receive their regular dose of CONCERTA (methylphenidate HCl). The primary efficacy variable in this study is the Permanent Product Math Test (PERMP) attempted score. Secondary Measures include: SKAMP (Swanson, Kotkin, Agler, M-Flynn, and Pelham), tests of inattention, reading fluency and comprehension, and memory. Assessments will be completed during each of the laboratory assessment days (12.5 hours). Participants will be assessed for adverse events throughout the study. Patients will initiate treatment with oral CONCERTA (methylphenidate HCl) 18 mg at baseline and continue morning dosing with increases every 3 to 7 days until an optimal dose is achieved, up to the maximum of 54 mg/day. Eligible patients will remain in the study for a maximum of 8 weeks.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Hour 4 Permanent Product Math Test Attempted Score (PERMP-Attempted)
Time Frame: Hour 4 of the Double-Blind Assessment Period Lab School Day
PERMP (range: 0, 400) is a measure of academic productivity. These seatwork math tasks provide an objective measure of attention and accuracy in calculations. The level of difficulty is established on a screening math pretest. The subsequent laboratory school day assessments employed a series of 10-minute math tests (5 pages of 80 math problem each for a total of 400 problems available). Children were graded on the number of attempted problems. A higher number of problems attempted was indicative of greater attention to detail (higher score is preferable.)
Hour 4 of the Double-Blind Assessment Period Lab School Day
Hour 4 Permanent Product Math Test Correct Score (PERMP-Correct)
Time Frame: Hour 4 of the Lab School Day During the Double-Blind Assessment Period
PERMP (range: 0, 400) is a measure of academic productivity. These seatwork math tasks provide an objective measure of attention and accuracy in calculations. The level of difficulty is established on a screening math pretest. The subsequent laboratory school day assessments employed a series of 10-minute math tests (5 pages of 80 math problem each for a total of 400 problems available). Children were graded on the number of correct problems. A higher number of problems correct, of those attempted, was indicative of greater accuracy.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Hour 5.5 Wide Range Assessment of Memory and Learning (WRAML-2) Finger Windows Backwards
Time Frame: Hour 5.5 of the Lab School Day During the Double-Blind Assessment Period
WRAML-2 (range: 0, 28) is designed to evaluate a child's ability to learn and to memorize information, consists of 9 subtests from which 4 summary indexes can be calculated: verbal memory index, visual memory index, learning index, and general memory index. During this test the investigator pointed to a longer and longer series of windows on a card at the rate of 1 location per second, and then the child was asked to reproduce the sequence exactly in reverse order. One point was given for each correctly recalled sequence, and the test was discontinued after 3 consecutive errors.
