Tris Pharma Announces FDA Approval of DYANAVEL® XR (amphetamine) Once-Daily Extended-Release Oral Tablets, CII, for ADHD

  • In a clinical study in adults, DYANAVEL XR tablets demonstrated bioequivalence to DYANAVEL XR (amphetamine) extended-release oral suspension.
  • ADHD patients taking Dyanavel XR oral suspension can conveniently switch to the same dose of DYANAVEL XR Tablets.
  • With multiple dosage strengths, including one functionally-scored, DYANAVEL XR extended-release tablets offer several dosing and titration options.

MONMOUTH JUNCTION, NJ, Nov 5, 2021/ PRNewswire/ – Tris Pharma, Inc. (Tris) announced today that the U.S. Food and Drug Administration has approved Dyanavel XR (amphetamine), extended release once-daily tablets, CII, for the treatment of Attention-Deficit Hyperactivity Disorder (ADHD) in patients 6 years and older.

In a clinical study in healthy adults, DYANAVEL XR extended-release tablets were deemed to be bioequivalent to DYANAVEL XR extended-release oral suspension, which in a Phase 3 clinical study of 6 to12 year-old children 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).

In a separate 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 post-dose time points measured (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 (at least 5%) adverse reactions were insomnia, dry mouth, headache, irritability, nausea, dizziness, initial insomnia and tachycardia. Tris plans to submit these findings for publication in a peer-reviewed scientific journal and to FDA at a future date.

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.

“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 tablets expands Tris’ ADHD portfolio and highlights Tris’ 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 professional a new option when treating adults with ADHD.

“The approval of DYANAVEL XR tablets, which utilize Tris’ LiquiXR® technology platform, fills an important gap in Tris’ portfolio of ADHD products to fit the needs of a variety of patient types. Dyanavel XR oral suspension and now DYANAVEL XR tablets provide a unique pharmacokinetic profile and a broad range of dosing options for patients needing an amphetamine for their ADHD”, said Dr. James Hackworth, President of the Tris Branded Products Division.

DYANAVEL XR tablets are expected to be stocked in pharmacies in the first quarter of 2022.
