Tonix Pharmaceuticals Announces Conditional Acceptance of Tonmya® as Proposed Brand Name for TNX-102 SL (Cyclobenzaprine HCl Sublingual Tablets) for the Treatment of PTSD

NEW YORK, July 06, 2017 -- Tonix Pharmaceuticals Holding Corp. (Nasdaq:TNXP) (Tonix) a company that is developing innovative pharmaceutical products to address public health challenges today reported that the U.S. Food and Drug Administration (FDA) has conditionally accepted the proposed trade name Tonmya (ton-MY-ah) for TNX-102 SL* (cyclobenzaprine HCl sublingual tablets) for the management of posttraumatic stress disorder (PTSD). Tonix recently launched the Phase 3 HONOR study of Tonmya in military-related PTSD, from which topline results are expected to be reported in the second half of 2018. Tonmya was designated a Breakthrough Therapy by the FDA for the treatment of PTSD.

A request for proprietary name review for Tonmya will be submitted once the PTSD New Drug Application (NDA) is submitted. FDA's final approval of Tonmya is subject to NDA approval. A request for review of Tonmya as the proposed name for TNX-102 SL for the management of fibromyalgia has been withdrawn at the FDA. The U.S. Patent and Trademark Office has granted the federal registration of the Tonmya mark.

*TNX-102 SL (cyclobenzaprine HCl sublingual tablets)/Tonmya is an investigational new drug and has not been approved for any indication.

About Tonmya and the Phase 3 HONOR Study

Tonmya (cyclobenzaprine HCl sublingual tablets) is a patented sublingual transmucosal formulation of cyclobenzaprine that is in Phase 3 development. PTSD is a serious condition characterized by chronic disability, inadequate treatment options, especially for military-related PTSD, and an overall high utilization of healthcare services that contributes to significant economic burdens. In a Phase 2 study, Tonmya 5.6 mg (2 x 2.8 mg tablets), was found to be effective in treating military-related PTSD, which formed the basis of the Breakthrough Therapy designation granted by the FDA. Tonix is currently conducting a Phase 3 trial of Tonmya in military-related PTSD in the United States, the HONOR study, which is a 12-week randomized, double-blind, placebo-controlled trial evaluating the efficacy of Tonmya 5.6 mg in participants with military-related PTSD. This two-arm, adaptive-design trial is targeting enrollment of up to approximately 550 participants across approximately 35 clinical sites. An unblinded interim analysis will be conducted once the study has accumulated efficacy results from approximately 275 randomized participants. In a recent Cross-Disciplinary Breakthrough Therapy meeting, the FDA confirmed that a single-study NDA approval could be possible if the topline data from the HONOR study are statistically very persuasive. Additional details of the HONOR study are available at www.thehonorstudy.com or https://clinicaltrials.gov/ct2/show/NCT03062540. The U.S. Patent and Trademark Office has issued a patent (U.S. Patent No. 9,636,408) protecting the composition and manufacture of the unique Tonmya formulation. The Protectic™ protective eutectic and Angstro-Technology™ formulation claimed in the patent are important elements of Tonix’s proprietary Tonmya composition. This patent is expected to provide Tonmya, upon NDA approval, with U.S. market exclusivity until 2034.
