Tonix Pharmaceuticals Presents on the Development of TNX-102 SL for Post-Traumatic Stress Disorder (PTSD) at the 2015 Military Health System Research Symposium

NEW YORK, Aug. 18, 2015 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (NASDAQ:TNXP) ("Tonix") today presented an overview of its development of TNX-102 SL (cyclobenzaprine HCl sublingual tablets) for PTSD, including a review of the design of the AtEase Clinical Study, at the 2015 Military Health System Research Symposium held in Fort Lauderdale, Florida.

Gregory M. Sullivan, M.D., Tonix's Chief Medical Officer, presented a poster entitled, "The AtEase Study: An Evaluation of the Efficacy of a Low Dose, Bedtime, Sublingual Formulation of Cyclobenzaprine (TNX-102 SL tablet) for the Treatment of Military-Related PTSD" (Abstract ID: MHSRS-15-0900; Poster ID: 1220).

"PTSD is a serious chronic illness, and many of those with military-related PTSD do not respond to existing treatments. There is an urgent unmet medical need for this patient population," said Seth Lederman, M.D., chairman and CEO of Tonix. "Recruitment into AtEase recently reached 50% of its target enrollment goal of 220 patients, and we expect to report top line data in the first half of 2016."

About the AtEase Clinical Study

The AtEase Clinical Study is a randomized, double-blind, placebo-controlled clinical trial to evaluate the efficacy and safety of TNX-102 SL for the treatment of patients with military-related PTSD. The trial is expected to enroll approximately 220 participants who will receive study medication daily at bedtime for twelve weeks. The primary efficacy endpoint will evaluate the performance of TNX-102 SL 2.8 mg on the total Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) score. Tonix expects to report top-line results in the first half of 2016. To learn more, please visit www.ateasestudy.com.

About TNX-102 SL

TNX-102 SL efficiently delivers a low dose of cyclobenzaprine to the bloodstream via sublingual (under the tongue) absorption, and is designed for chronic use at bedtime to improve sleep quality. As a multifunctional agent with antagonist activities at the serotonin-2A, alpha-1 adrenergic, and histamine H1 receptors, TNX-102 SL is intended to provide broad-spectrum symptom improvement in PTSD by targeting sleep and the stress response.

About Post-Traumatic Stress Disorder

PTSD afflicts approximately 8.5 million Americans each year, and its prevalence rate in the military population is higher than that among civilians. Both of the drugs approved by the U.S. Food and Drug Administration (FDA) for PTSD lack reliable evidence of efficacy in combat-related trauma and carry suicidality warnings.
