Nov. 4, 2009 (PR Newswire) --
LAS VEGAS, Nov. 4 /PRNewswire/ -- New findings presented today show that CONCERTA® (OROS® methylphenidate HCl Extended-Release Tablets CII) is the only stimulant medication with data that demonstrate a significant treatment effect on attention at one hour and through 12.5 hours in children with Attention Deficit Hyperactivity Disorder (ADHD). ADHD is a common and treatable medical condition characterized by inattention, hyperactivity and impulsivity(1) that is estimated to affect about 5 million children(2) in the United States.

McNeil Pediatrics(TM), Division of Ortho-McNeil-Janssen Pharmaceuticals, Inc., presented the data at the U.S. Psychiatric and Mental Health Congress (Poster 303: Time Course of Treatment Effect of Concerta® [OROS® Methylphenidate] in Children with ADHD).
This is the first data set from new studies that examine the effect of CONCERTA® in a laboratory school, or simulated classroom, setting. The data presented today provide new information on CONCERTA® onset and offset of action in the treatment of children (aged 9 to 12 years) with ADHD.
"Untreated ADHD symptoms can present challenges throughout a child's day, so new findings on onset and duration of effect are important to understand," said Matthew Brams*, M.D., a practicing psychiatrist in Houston, Clinical Assistant Professor at Baylor College of Medicine and an investigator who participated in one of the studies. "There's benefit in medication that acts quickly and lasts through the day, providing treatment coverage when a child may need it in the early morning, through the activities of the day and into the early evening hours."
The results presented today showed significant improvements in attention with CONCERTA® versus placebo as measured by a validated, time-sensitive math test administered throughout the day.
At one hour post-dose, subjects who received CONCERTA® attempted 38 percent more math problems compared with baseline (from 75.8 problems attempted before treatment to 104.4 problems attempted after treatment), while those receiving placebo showed no change from baseline (from 80.6 problems attempted before treatment to 80 problems attempted after treatment).
The results were statistically significant throughout the study's interim time points, from the first testing point at one hour after dosing (p<0.0001) through to the final assessment at 12.5 hours (p<0.0001). Accuracy, as measured by percentage of problems correct, was similar for both treatment groups and was consistent across the period of observation (placebo, 92.1 percent to 93.5 percent and CONCERTA®, 94.0 percent to 94.3 percent).
Adverse events in the study were consistent with those previously reported for CONCERTA®. Adverse events reported by 5 percent or more of the patients during the study included decreased appetite, abdominal pain, headache, irritability, initial insomnia, nasal congestion, pyrexia and dizziness. No subject discontinued because of adverse events, and no serious adverse events or deaths were reported.

About the Poster
This is the first data set from two randomized, double-blind, placebo-controlled, crossover analog simulated-classroom trials examining CONCERTA® versus placebo. These studies include a wide range of endpoints based on standardized ADHD measurements, which were tested in a simulated classroom environment, as well as observational input from subjects' parents, teachers and physicians.
