Condition(s) targeted: Attention Deficit Hyperactivity Disorder (ADHD)

Intervention: AR11 (Drug)

Phase: Phase 4

Status: Completed

Sponsored by: Arbor Pharmaceuticals, Inc.

Official(s) and/or principal investigator(s):
Laurence Downey, MD, Study Director, Affiliation: Arbor Pharmaceuticals, LLC.


This is a dose-optimized, randomized, double-blind, placebo-controlled crossover study in approximately 100 pediatric patients (aged 6 to 12 years) with ADHD. Eligible patients will enroll in the study to take open-label AR11 twice daily and undergo dose optimization activities for 8 weeks. Patients who achieve a stable dose during the dose optimization period will continue participation and will be randomized to take double-blind medication (AR11 or placebo) orally twice daily for 1 week. At the end of the first double-blind treatment period, patients will be evaluated for ADHD symptoms in a laboratory classroom setting utilizing SKAMP and PERMP assessments. At the end of the second double blind treatment period, patients will be evaluated for ADHD symptoms in a second laboratory classroom setting utilizing SKAMP and PERMP assessments.
