Tris Pharma Announces Availability of New DYANAVEL® XR (amphetamine) Tablets for ADHD

Published: Aug. 16, 2022 at 6:30 AM CDT

Once daily extended release provides early onset and full day coverage

MONMOUTH JUNCTION, N.J. , Aug. 16, 2022 /PRNewswire/ -- Tris Pharma, Inc. (Tris) a fully integrated pharmaceutical company with a robust portfolio of CNS products announced today that DYANAVEL® XR (amphetamine) extended-release tablets, for oral use, CII are now available in pharmacies. DYANAVEL XR was approved by the U.S. Food and Drug Administration for the treatment of Attention-Deficit Hyperactivity Disorder (ADHD) in patients 6 years and older.

In a double-blind, placebo-controlled, fixed-dose Phase 3 study in adults with ADHD, DYANAVEL XR tablets demonstrated statistically significant improvement versus placebo in mean Permanent Product Measure of Performance Total (PERMP-T) scores averaged across all measured post-dose time points (0.5, 1, 2, 4, 8, 10, 12, 13, and 14 hours post-dose). The PERMP-T is a validated and FDA-accepted, skill-adjusted, timed math test that is used to assess attention in people with ADHD. The most common adverse events included headache, decreased appetite, irritability, initial insomnia, insomnia, dry mouth, anxiety, dizziness, tachycardia, fatigue, and nausea. Most treatment-emergent AEs (TEAEs) were mild to moderate in severity, and no SAEs were reported during the study. These finds were recently published in The Journal of Clinical Psychiatry (Cutler, et al. J Clin Psychiatry 2022. 83(00):22m14438).

In another clinical study in healthy adults, DYANAVEL XR extended-release tablets were deemed to be bioequivalent to DYANAVEL XR (amphetamine) extended-release oral suspension CII, which in a Phase 3 clinical study of children aged 6 to 12 years with ADHD, demonstrated ADHD symptom improvement within 1 hour, that lasted through 13 hours after once-daily dosing. Further, in a separate exploratory study, DYANAVEL XR oral suspension appeared to improve ADHD symptoms as soon as 30 minutes after dosing (Pardo, et al. CNS Spectrums 2020 Dec:25(6):774-781).

"The Dyanavel XR tablet represents an important treatment option for patients with ADHD," said Andrew J. Cutler, CMO, Neuroscience Education Institute and Clinical Associate Professor of Psychiatry, SUNY Upstate Medical University. "Knowing that ADHD in adults presents differently than in children, and as different adults have different treatment goals, DYANAVEL XR once-daily tablet was designed and developed with the intent to provide adults with ADHD a treatment option that kicks in quickly and lasts throughout their workday and beyond."

The approval of DYANAVEL XR extended-release tablets expands Tris's ADHD portfolio and highlights Tris's commitment to address the unmet needs of the ADHD community. Nearly 10 million adults in the U.S. have ADHD. Over 90% of cases are untreated and at least 75% of adults who have ADHD don't know it. Offering DYANAVEL XR in a tablet formulation gives healthcare professionals a new option when treating adults with ADHD.

"Tris is committed to bring innovative ADHD products to all patients. Due to Tris's proprietary LiquiXR technology, this is the first ADHD product that gives adult patients a choice when an early onset is desired without sacrificing full day coverage.," said Dr. James Hackworth, President of the Tris Branded Products Division. "We expect that this product will fill a big current gap in treatment options and help patients to not have to choose between early morning and evening coverage."

DYANAVEL XR is a federally controlled substance (CII) because it contains amphetamine that can be a target for people who abuse prescription medicines or street drugs. Keep DYANAVEL XR in a safe place to protect it from theft. Never give your DYANAVEL XR to anyone else because it may cause death or harm them. Selling or giving away DYANAVEL XR may harm others and is against the law. See additional important safety information below.
