• Study met primary endpoint measure of sustained attention in adults with ADHD
• Showed statistically significant improvement vs. placebo in mean PERMP-Total score measured from 0.5 hours to 14 hours post-dose 
• No new adverse reactions reported during the study

MONMOUTH JUNCTION, NJ, January 20, 2021 / PRNewswire/ – Tris Pharma, Inc. (“Tris”), a specialty pharmaceutical company with a robust portfolio of approved products and a late-stage pipeline of innovative product candidates for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) and related disorders, today announced that it presented data from a pivotal efficacy and safety study on its new amphetamine extended-release tablet at the virtual annual meeting of American Professional Society of ADHD and Related Disorders (APSARD), January 15 – 17, 2021.

Results from the study, entitled “Randomized, Double-Blind, Placebo-Controlled, Fixed-Dose Study to Evaluate the Efficacy and Safety of the Amphetamine Extended-Release Tablet in Adults with Attention-Deficit/Hyperactivity Disorder,” were reported during the annual APSARD meeting. The study was designed to evaluate the efficacy and safety of amphetamine extended-release tablets in adults aged 18-60 years with ADHD compared with placebo.

The primary efficacy endpoint was met: the mean Permanent Product Measure of Performance total (PERMP-T) score over all post dose time points was statistically significantly higher in the amphetamine extended-release tablet group compared with placebo (302.8 vs 279.6; p=0.0043). Additionally, statistically significant improvements (increase) in PERMP-T scores were observed in the amphetamine extended-release tablet group as early as 0.5 hours (p=0.0115) and as late as 13 hours (p=0.0056) post dose compared with placebo. Most common adverse events included headache, decreased appetite, irritability, initial insomnia, insomnia, dry mouth, and nausea. Most treatment-emergent AEs (TEAEs) were mild to moderate in severity, and no SAEs were reported during the study.

Amphetamine extended-release tablet is an investigational agent and is not currently approved for use in any country. It is currently under review at the U S Food and Drug Administration

“The results of this study demonstrate the efficacy of the amphetamine extended-release tablet in treatment of ADHD in adults,” said Andrew J. Cutler, MD, Clinical Associate Professor of Psychiatry, SUNY Upstate Medical University and the principal investigator of the study. “When you look at the totality of the efficacy results, coupled with what we know about Dyanavel® XR pharmacokinetics and pharmacodynamics, you can see that the drug is working shortly after dosing, and is still providing efficacy 13 hours post dose.”
