Tonix Pharmaceuticals Reports Second Quarter 2015 Financial Results and Provides Program Update

Key Clinical Results in Fibromyalgia, Post-Traumatic Stress Disorder, and Tension Headache to be Reported in 2016

NEW YORK, Aug. 10, 2015 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (NASDAQ:TNXP) ("Tonix"), a clinical-stage pharmaceutical company developing next-generation medicines for fibromyalgia, post-traumatic stress disorder (PTSD), and episodic tension-type headache, announced financial results for the second quarter ended June 30, 2015.

"In the first half of this year, we achieved our goal of initiating efficacy studies in tension headache, post-traumatic stress disorder, and fibromyalgia, all large therapeutic indications. We look forward to reporting results from each of these three trials in 2016 as we advance our programs through the clinical development process," said Seth Lederman, M.D., Tonix's chairman and CEO.

Tonix ended the June 30, 2015 quarter with $48.7 million in cash and cash equivalents. Tonix raised $18.7M in net proceeds from an underwritten offering completed in July 2015.

Recent Clinical Highlights and Upcoming Milestones

• Tonmya™ (cyclobenzaprine HCl sublingual tablets, 2.8 mg) – fibromyalgia
  • We commenced the 500-patient Phase 3 AFFIRM clinical study in fibromyalgia in May 2015.
  • AFFIRM is a randomized, double-blind, placebo-controlled, 12-week trial of Tonmya taken sublingually at bedtime daily.
  • The primary efficacy endpoint is a 30% pain responder analysis at week 12.
  • We expect to report top-line results in the second half of 2016.

Fibromyalgia afflicts five to 15 million Americans, and physicians and patients report widespread dissatisfaction with currently marketed products. To learn more, please visit www.affirmstudy.com.

• TNX-102 SL (cyclobenzaprine HCl sublingual tablets) – post-traumatic stress disorder
  • We commenced the 220-patient Phase 2 AtEase clinical study in military-related PTSD in January 2015.
  • AtEase is a randomized, double-blind, placebo-controlled, 12-week trial of TNX-102 SL 2.8 mg and 5.6 mg taken sublingually at bedtime daily.
  • The primary efficacy endpoint will evaluate performance of TNX-102 SL 2.8 mg on the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5).
  • We expect to report top-line results in the first half of 2016.

PTSD afflicts approximately 8.5 million Americans, and its prevalence 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 this disorder lack evidence of efficacy in combat-related PTSD and carry suicidality warnings.

• TNX-201 (dexisometheptene mucate) – episodic tension-type headache
  • A randomized, double-blind, placebo-controlled Phase 2 proof-of-concept (POC) study in episodic tension-type headache is underway and will evaluate the potential benefit of TNX-201 according to a variety of efficacy measures, as well as safety and tolerability.
  • The target enrollment is 200 patients, and we expect to report top-line results in the first quarter of 2016.

Millions of Americans suffer from episodic tension-type headache, yet prescription medications are limited for the many who find over-the-counter options to be inadequate. All of the FDA-approved prescription drugs for this condition contain a barbiturate, and no new prescription medication for tension-type headache has been approved in over 40 years. To learn more, please visit www.clinicaltrials.gov (NCT02423408).

Second Quarter Financial Results

For the three months ended June 30, 2015, Tonix reported a net loss of $11.8 million, or $0.73 per share, as compared to a net loss of $6.0 million, or $0.61 per share, for the second quarter of 2014. The higher net loss was primarily due to increased research and development expense for clinical studies and related research as well as increased general and administrative expense to support these and other corporate development activities. Cash used in operations was $18.3 million for the six months ended June 30, 2015, as compared to $9.8 million for the six months ended June 30, 2014. At June 30, 2015, Tonix's cash and cash equivalents totaled $48.7 million as compared to $38.2 million at December 31, 2014.
