Tonix Pharmaceuticals Initiates Enrollment in Phase 2b BESTFIT Trial of TNX-102 SL in Fibromyalgia Patients

NEW YORK, NY -- (Marketwired) -- 09/16/13 -- Tonix Pharmaceuticals Holding Corp. (NASDAQ: TNXP), a development stage specialty pharmaceutical company, today announced the start of its Phase 2b BESTFIT (BEdtime Sublingual TNX-102 SL as Fibromyalgia Intervention Therapy) trial of the Company's lead therapeutic candidate, TNX-102 SL 2.8 mg tablets, in patients with fibromyalgia.

BESTFIT is a randomized, double-blind trial of TNX-102 SL versus placebo in patients diagnosed with primary fibromyalgia. The trial is expected to enroll approximately 120 patients who will be randomized (1:1) to receive either TNX-102 SL or placebo tablets, taken sublingually at bedtime, daily for 12 weeks. The trial will be conducted at approximately 13-15 U.S. sites. The primary endpoint of the trial is change in pain intensity at week 12 from baseline, as evaluated by scoring on the 11-point Numeric Rating Scale. Safety and tolerability of TNX-102 SL taken at bedtime over 12 weeks will also be evaluated.

The Study Chair of the BESTFIT trial is Daniel J. Clauw, M.D., Professor of Anesthesiology, Medicine, and Psychiatry and Director of the Chronic Pain and Fatigue Research Center at the University of Michigan.

"Enrollment of the first patient in the BESTFIT trial of TNX-102 SL in fibromyalgia represents an important milestone in the clinical development of TNX-102 SL and for Tonix as a company. We look forward to completing this trial in time to report the top-line results in the second half of 2014," said Seth Lederman, M.D., Chief Executive Officer and President of Tonix. "We continue to pursue opportunities for TNX-102 SL in other indications, including post-traumatic stress disorder," he added.
