A solid performance in the classroom study

The EVEKEO classroom study included 97 children with ADHD1

Before we tell you the classroom study results, you may be wondering what a classroom study is. Here’s how the researchers explain it:

A laboratory classroom setting for study of ADHD medications allows for assessment by trained observers over the course of a typical extended school day….1*

*This study was a post-approval study. Post-approval studies are used to assess the continued safety and effectiveness of an already approved medication.

How pediatric study patients with ADHD were evaluated

In a classroom study of children ages 6 to 12 years with ADHD, the researchers were looking to see how EVEKEO® CII (amphetamine sulfate tablets, USP) affected the following1:

†The math test was adjusted for the skill level of the child and wasn’t intended to see how well the child could learn math. Instead, it was to assess the child’s level of attention.

The children were evaluated multiple times over a 10-hour span on 2 different classroom days. On one classroom day, they received EVEKEO. On the other classroom day, they received a pill that looks exactly like EVEKEO but doesn't contain any medication, called a placebo. Results from the 2 days were compared to determine not only the effect EVEKEO had on symptoms, but also how long the effect lasted.1

Children who were excluded from the study included those with a primary psychiatric diagnosis other than ADHD, or those with a secondary or co-morbid diagnosis other than ADHD with the exception of simple phobias, oppositional defiance disorders, motor skill disorders, communication disorders, learning disorders, adjustment disorders, and sleep disorders. Others who were excluded from the study were children with clinically significant cognitive impairment or a personal history of seizure disorders (except simple febrile seizures), untreated thyroid disease, glaucoma, Gilles de la Tourette's disorder, or chronic tics, as well as those with a personal history of cardiac disorders, serious cardiac conditions, or severe hypertension.1

PERMP Test Results From a Real Classroom Study Subject With ADHD2

The results

EVEKEO significantly improved performance, behavior, and attention at every measured time point, from 45 minutes to 10 hours.1

  • Improved performance: Children attempted to solve more problems on the PERMP, and answered more problems correctly, after taking EVEKEO compared with placebo (see example below)
  • Improved behavior and attention: When the scores of the 13-item scale were combined, EVEKEO was shown to have significantly improved behavior and attention measured by the SKAMP scale compared with placebo
