NEW YORK, May 26, 2016 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (NASDAQ:TNXP) (Tonix), which is developing next-generation medicines for fibromyalgia and post-traumatic stress disorder (PTSD), announced that it will present positive data from the Phase 2 dose-finding clinical study of TNX-102 SL (cyclobenzaprine HCl sublingual tablets) for the treatment of military-related PTSD (AtEase Study). Data will be featured in oral and poster presentations at the American Society of Clinical Psychopharmacology Annual Meeting (ASCP, formerly NCDEU) being held May 30 – June 3, 2016 in Scottsdale, Arizona.
Tonix’s abstract entitled, “A Randomized Placebo-controlled Multicenter Trial of a Low-dose Bedtime Sublingual Formulation of Cyclobenzaprine (TNX-102 SL*) for the Treatment of Military-Related PTSD,” will be presented by Gregory Sullivan, M.D., Tonix’s chief medical officer on Tuesday, May 31 at 2:00 p.m. MST. Dr. Sullivan also will present Tonix’s trial data in a poster presentation during Poster Session I, being held on Wednesday, June 1 from 11:15 a.m. – 2:00 p.m. MST.
The AtEase clinical study was a randomized, placebo-controlled study of 231 patients with PTSD at 24 U.S. clinical sites. A bedtime sublingual dose of 2.8 mg TNX-102 SL (n=90) or 5.6 mg TNX-102 SL (n=49) was compared to placebo (n=92) for the treatment of military-related PTSD. The retention rates were 79% on TNX-102 SL 2.8 mg, 84% on TNX-102 SL 5.6 mg, and 73% on placebo. The primary efficacy endpoint was the 12-week mean change from baseline in the severity of PTSD symptoms as measured by the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) between those treated with TNX-102 SL 2.8 mg and those receiving placebo. The CAPS-5 is a standardized structured clinical interview and serves as the gold standard in research for measuring the symptom severity of PTSD.

About Post-Traumatic Stress Disorder
PTSD can develop from witnessing or experiencing a traumatic event or ordeal in which there was the severe threat or actual occurrence of grave physical harm. PTSD affects approximately 8.4 million Americans in any year and is a chronic and severely debilitating condition in which patients re-experience the horrific traumas that resulted in the condition in the forms of intrusive memories, flashbacks, and nightmares. PTSD is characterized by disrupted sleep, anxiety, agitation, avoidance, emotional numbness and estrangement from family and friends, guilt or negative beliefs about self, and is sometimes associated with clinical depression, substance use disorders, and unpredictable violent or suicidal behaviors. Individuals who suffer from PTSD usually have significant impairment in social functioning, occupational disability, and an overall poor quality of life. It is estimated that 20 percent of the over 2.5 million US military personnel returning from tours of duty in the recent conflicts in Iraq and Afghanistan suffer from PTSD1.
