Tonix Has Pre-Phase 3 Meeting with FDA Regarding Proposed New Fibromyalgia Drug

  [ Not Yet Rated ]   [ 1 Comment ] • March 18, 2013

Editor's note:  Tonix Pharmaceuticals has completed Phase 1 and Phase 2a clinical trials on a new drug for fibromyalgia with positive results.  TNX-102, the proposed new drug, is actually a new sublingual formulation of an old drug – cyclobenzaprine, probably best known by the brand name Flexaril.  Cyclobenzaprine is a muscle relaxant that works by blocking nerve impulses (or pain sensations) that are sent to the brain.  The company sent out the following press release regarding their recent meeting with the FDA.

Regulatory Acceptance of Design of Registrational Clinical Studies; Dosing in First Safety and Efficacy Trial to Commence in the Third Quarter of 2013

NEW YORK, NY -- (MARKETWIRE) -- 03/11/13 -- Tonix Pharmaceuticals Holding Corp. (OTCQB: TNXP) ("TONIX" or "the Company"), a specialty pharmaceutical company developing novel treatments for challenging disorders of the central nervous system, including fibromyalgia ("FM") and post-traumatic stress disorder ("PTSD"), announced that it recently held an End-of-Phase 2/Pre-Phase 3 meeting with the U.S. Food and Drug Administration ("FDA") to discuss its proposed New Drug Application ("NDA") plan for the Company's novel sublingual tablet formulation of cyclobenzaprine for bedtime use, TNX-102 SL, for the management of FM. Official FDA meeting minutes indicate FDA acceptance of the clinical program and provide clear direction to achieve a successful NDA filing of TNX-102 SL in FM.

The registrational clinical trials will consist of two randomized, double-blind, placebo-controlled 12-week safety and efficacy studies in FM patients who will take either a TNX-102 SL (cyclobenzaprine HCl 2.8 mg) tablet or placebo at bedtime. The primary endpoint of both trials will be the change in pain from baseline to Week 12 as measured by the Numeric Rating Scale. The Company plans to conduct these trials in sequence, and expects to begin dosing in the first trial in the third quarter of 2013. This trial will enroll 100 to 200 FM patients, and top-line data are anticipated to become available in the second half of 2014.

Following the completion of the double-blind randomized portion of these studies, patients may be eligible to enroll in open-label extension studies of TNX-102 SL. The FDA agreed that the safety database needed to support a 505(b)(2) NDA submission for TNX-102 SL would contain a total exposure of at least 300 FM patients, with at least 100 patients receiving TNX-102 SL for six months and at least 50 patients for one year.

Seth Lederman, M.D., Chief Executive Officer of TONIX, said, "We view our meeting with the FDA as a major milestone for TONIX. We are pleased to have concurrence from the FDA on the design and selection of efficacy endpoints of our registrational clinical studies in FM in addition to receiving clear guidance on the remaining requirements for the TNX-102 SL NDA program. We are also pleased with the FDA's requirements on chronic exposure, which are appropriately less than those typically needed for a new drug to be approved for a chronic use indication. We look forward to advancing TNX-102 SL towards a successful NDA filing."

About Tonix Pharmaceuticals Holding Corp.
TONIX is developing innovative prescription medications for challenging disorders of the central nervous system. The Company targets conditions characterized by significant unmet medical need, inadequate existing treatment options, and high dissatisfaction among both patients and physicians. TONIX's core technology improves the quality of sleep in patients with chronic pain syndromes, which is believed to translate into reductions in pain and other symptoms. An Investigational New Drug Application ("IND") has been filed for the Company's lead product candidate, TNX-102 SL, a novel under-the-tongue tablet formulation of cyclobenzaprine, the active ingredient in two FDA-approved muscle relaxants. TONIX expects to begin a registrational clinical study of TNX-102 SL in FM in the third quarter of 2013. TONIX expects to file an IND for TNX-102 SL in PTSD in the third quarter of 2013, and to begin a Phase 2 trial in this indication in the fourth quarter of 2013. To learn more, please visit
