Tris Pharma Announces Continued Supply and Availability of DYANAVEL® XR (amphetamine) Tablets and Oral Suspension for ADHD Despite Adderall shortage

Once daily extended release provides early onset and full day coverage

MONMOUTH JUNCTION, N.J., Oct. 19, 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 and DYANAVEL® XR (amphetamine) extended-release oral suspension, CII are stocked by wholesalers and continue to be 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. Dyanavel XR may be an option for health care providers and patients who can no longer fill their prescription of Adderall due to a stocking shortage.

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.

“With the Innovative Tris portfolio of ADHD products, we are committed to help Providers and Patients through their treatment journey. DYANAVEL XR Tablet and DYANAVEL XR oral suspension provide quality treatment options for adult and pediatric patients 6 years and older with ADHD who need an amphetamine”, said Dr. James Hackworth, President of the Tris Branded Products Division.
