Tonix Pharmaceuticals Reports Outcomes from U.S. FDA Breakthrough Therapy CMC Guidance Meeting of Tonmya® (Cyclobenzaprine HCI Sublingual Tablets) for PTSD
NEW YORK, Oct. 17, 2017 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (Nasdaq:TNXP) (Tonix), a company that is developing innovative pharmaceutical and biological products to address public health challenges, announced today the receipt of official minutes from a chemistry, manufacturing and controls (CMC) guidance meeting with the U.S. Food and Drug Administration (FDA) regarding the CMC data required to support the Tonmya* (cyclobenzaprine HCI sublingual tablets), or TNX-102 SL, New Drug Application (NDA) and the commercial product. Tonix is in Phase 3 development of Tonmya, an FDA-designated Breakthrough Therapy for the treatment of posttraumatic stress disorder (PTSD).
Seth Lederman, M.D., president and chief executive officer of Tonix, stated, “Tonix has been successfully implementing the commercial production strategy for TNX-102 SL in addition to manufacturing final drug product to support the required clinical studies for the Tonmya NDA. The CMC guidance meeting we had with the FDA in September is part of our effort to ensure our NDA CMC plan is supportive of the Tonmya’s registration plan, which is usually a big challenge for an accelerated Breakthrough Therapy development program. In general, our proposed CMC data package to support the Tonmya’s NDA and commercial manufacturing plans was accepted by the FDA. The FDA official minutes reflect our readiness to manufacture Tonmya commercial product at production scale, which is critical to the successful launch of a potentially improved treatment option for PTSD patients, especially those patients with military-related PTSD.”
*Tonmya has been conditionally accepted by the 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.
About Tonmya and the Phase 3 HONOR Study
Tonmya 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 in approximately 45 U.S. 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 (i) a single-study new drug application (NDA) approval could be possible if the topline data from the HONOR study are statistically very persuasive, and (ii) an additional abuse assessment study is not required for the NDA filing. 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 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.
Tonix was awarded European patent (Patent No. 2501234, “Methods and Compositions for Treating Symptoms Associated with Posttraumatic Stress Disorders Using Cyclobenzaprine”). This patent is expected to provide Tonmya, upon European marketing authorization, with European market exclusivity until November 2030 and the exclusivity may be extended based on the timing of the European marketing authorization of Tonmya for PTSD.
