Tonix Pharma Receives European Patent For The Active Ingredient In Tonmya (Cyclobenzaprine HCL Sublingual Tablets)

Published: Sep 15, 2017

- Patent Will Provide Intellectual Property Protection until 2030 for Use of Cyclobenzaprine in the Treatment of Posttraumatic Stress Disorder (PTSD)

NEW YORK, Sept. 14, 2017 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (Nasdaq:TNXP) (Tonix), a company developing innovative pharmaceutical and biological products to address major public health challenges, today announced that Tonix has received a European patent (Patent No. 2501234, “Methods and Compositions for Treating Symptoms Associated with Posttraumatic Stress Disorders Using Cyclobenzaprine”). This patent protects the use of Tonmya*, or TNX-102 SL, for the treatment of PTSD. The patent expires in November 2030 and may be extended based on the timing of the European marketing authorization of Tonmya for PTSD. Tonix is in Phase 3 development of Tonmya, a U.S. Food and Drug Administration (FDA)-designated Breakthrough Therapy for the treatment of PTSD.

“The grant of this European methods and compositions use patent is a big step forward for the global Tonmya development program,” commented Seth Lederman, M.D., president and chief executive officer of Tonix. “Adding this European use patent to the existing Tonmya U.S. composition of matter patent** can provide us broad protection of using cyclobenzaprine to treat PTSD in major pharmaceutical markets.”

This patent protects the use of Tonmya’s active ingredient cyclobenzaprine for the treatment of PTSD. The Tonmya eutectic formulation of cyclobenzaprine for under-the-tongue administration allows transmucosal absorption of cyclobenzaprine, which bypasses first pass liver metabolism. Other forms of cyclobenzaprine are approved for short-term use (two-three weeks) for relief of muscle spasm associated with acute, painful musculoskeletal conditions. Tonmya has a different route of administration and different pharmacokinetic profile than other marketed formulations of cyclobenzaprine and is intended for a new indication (PTSD).

* Tonmya has been conditionally accepted by the U.S. Food and Drug Administration (FDA) as the proposed trade name for TNX-102 SL (cyclobenzaprine HCl sublingual tablets) for PTSD. TNX-102 SL is an investigational new drug and has not been approved for any indication.

** U.S. Patent 9,636,408 was issued covering the proprietary sublingual formulation of cyclobenzaprine. This patent is expected to provide Tonix with U.S. market exclusivity until 2034.
