Tonix Pharmaceuticals Announces the Enrollment of Completers From the BESTFIT Trial Into a 12-Month Open-Label Extension Study

NEW YORK, Dec. 10, 2013 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (Nasdaq:TNXP), a development stage specialty pharmaceutical company, announced today that it is enrolling subjects into an open-label extension (OLE) study to the BESTFIT trial of TNX-102 2.8 mg sublingual tablet (SL) in fibromyalgia (FM).

The primary objective of the 12-month OLE study is to evaluate the long-term safety and tolerability of TNX-102 SL taken sublingually at bedtime once-daily in patients with FM. The secondary objective is to evaluate the long term efficacy of TNX-102 SL on the symptoms of FM. Subjects who complete the BESTFIT trial have the option to enroll into the OLE study, in which all participants will receive TNX-102 SL. Accepted by the Food and Drug Administration (FDA) as an abbreviated long-term safety exposure evaluation, this OLE study is being conducted to support a 505(b)(2) New Drug Application for TNX-102 SL as a chronic medication for the management of FM. The ongoing BESTFIT trial is the first of two anticipated placebo-controlled pivotal trials to support the efficacy and safety of TNX-102 SL in fibromyalgia.
