• If approved, AR19 would be the first-ever FDA-approved ADHD stimulant medication designed to resist manipulation for nonmedical use, which may help to deter misuse and abuse by intranasal, intravenous and smoking routes of administration

Atlanta, GA – May 13, 2020 – Arbor Pharmaceuticals, LLC, a U.S.-based specialty pharmaceutical company, announced today that the U.S. Food and Drug Administration (FDA) has accepted for filing its New Drug Application (NDA) for AR19, an investigational immediate-release, amphetamine capsule for the treatment of attention-deficit/hyperactivity disorder (ADHD) in children 3-17 years of age and in adults 18 and older. AR19 has been specifically designed to resist potential manipulation. The FDA has set a Prescription Drug User Fee Act (PDUFA) target action date of November 15, 2020.

“While stimulants are essential first-line therapies for ADHD, they are associated with potentially dangerous risks and side effects when used nonmedically, especially via non-oral routes of administration,” said Evan Scullin M.D., Medical Director, Arbor Pharmaceuticals. “Arbor has designed AR19 to resist manipulation to help address this public health concern of non-oral use, and we look forward to working closely with the FDA as it reviews our application.”

“Given the growth of nonmedical use of stimulant medications among the U.S. population, the development of a manipulation-resistant formulation of amphetamine is extremely important,” said Anthony Rostain, M.D., Chair of Cooper University Healthcare Department of Psychiatry and Behavioral Health and Professor Emeritus, Perelman School of Medicine, University of Pennsylvania. “It’s a vital step in making these helpful medications safer to use in clinical practice.”

Nonmedical use of prescription stimulants often begins in adolescence, and an estimated 1.7 million people aged 12 and older have used stimulants nonmedically within the past month.1 In a national survey of more than 19,000 college students, 16 percent reported nonmedically using stimulant medications, making them the most commonly misused prescription drugs on campuses, and the majority reported receiving the medications from a friend. In addition, a substantial proportion of nonmedical users report non-oral administration, or snorting, injecting or smoking prescription stimulants.2 In a recent survey of college students, snorting was reported by 21 percent of non-medical users, making intranasal administration the most prevalent non-oral route of stimulant nonmedical use.3

This problem is not limited to college students; a recent survey of children age 10-17 demonstrated that 30 percent of respondents with access to prescription stimulants had used them nonmedically and 45 percent of those nonmedical users had used non-orally.4 It is important to note that non-oral administration is associated with more severe clinical adverse effects, including death.5,6 

The AR19 NDA is supported by a comprehensive clinical program including studies that support the compound’s safety and efficacy for the treatment of children and adults and its manipulation-resistant properties.
