Tonix Pharmaceuticals Achieves 50 Percent Enrollment in RALLY, the Second Phase 3 Study of TNX-102 SL for Management of Fibromyalgia

Enrollment Continues in Phase 3 RALLY Study, with Interim Analysis of the First 50 Percent of Participants Expected Third Quarter 2021

Topline Results of Approximately 670 Participants in RALLY Expected Fourth Quarter 2021

Positive Topline Results from RELIEF, the First Phase 3 Study of TNX-102 SL for Management of Fibromyalgia, Previously Announced December 2020

CHATHAM, N.J., March 15, 2021 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced that 50 percent of the planned total number of participants have been randomized in the Phase 3 RALLY study (TNX-CY-F306) for the management of fibromyalgia. RALLY is the Company’s second of two potential pivotal Phase 3 studies of TNX-102 SL (cyclobenzaprine HCl sublingual tablets) 5.6 mg, a non-opioid, centrally acting analgesic, taken daily at bedtime. The RALLY study utilizes the same protocol design as the Company’s first positive Phase 3 study, RELIEF, but with an additional 200 patients.

“We believe that achieving this milestone keeps us on plan for the anticipated release of interim results from RALLY in the third quarter and topline data in the fourth quarter of this year,” said Tonix’s President and Chief Executive Officer, Seth Lederman, M.D. “If the topline results are positive, we expect to be in a position to submit a New Drug Application (NDA) for TNX-102 SL for fibromyalgia to the U.S. Food and Drug Administration (FDA) in 2022.”

In December 2020, the Company reported positive topline results from the RELIEF study, its first Phase 3 study for TNX-102 SL 5.6 mg in fibromyalgia. In the RELIEF study, the 5.6 mg dose achieved statistically significant pain reduction over placebo at Week 14 (primary endpoint, p=0.01). In addition, TNX-102 SL was generally well tolerated with an adverse event profile comparable to prior studies, and no new safety signals observed.

An interim analysis of the first 50 percent of randomized participants in the RALLY study will be conducted shortly after the 14-week treatment period has been completed by these participants. Pending approval of the interim statistical analysis plan by the FDA, results from the interim analysis are expected in the third quarter of 2021. The interim analysis will be conducted by an Independent Data Monitoring Committee (IDMC) which will review the unblinded data and make one of four recommendations: (1) stop the study for success; (2) continue to enroll the full study as planned; (3) continue to enroll with a specified increase in the total number of participants in the full study; or (4) stop the study for futility.

About the Phase 3 RALLY Study

The RALLY study is a double-blind, randomized, placebo-controlled trial designed to evaluate the efficacy and safety of TNX-102 SL (cyclobenzaprine HCl sublingual tablets). The two-arm trial is expected to enroll approximately 670 patients across approximately 40 U.S. sites. For the first two weeks of treatment, there is a run-in period in which participants start on TNX-102 SL 2.8 mg (1 tablet) or placebo. After the first two weeks, all participants have the dose increased to TNX-102 SL 5.6 mg (2 x 2.8 mg tablets) or two placebo tablets for 12 weeks. The primary endpoint is daily diary pain severity score change (TNX-102 SL 5.6 mg vs. placebo) from baseline (using the weekly averages of the daily numerical rating scale scores), analyzed by mixed model repeated measures with multiple imputation.

About Fibromyalgia

Fibromyalgia is a chronic pain disorder that is thought to result from amplified sensory and pain signaling. Fibromyalgia afflicts an estimated 6-12 million adults in the U.S, and physicians and patients report widespread dissatisfaction with currently marketed products. Common symptoms of fibromyalgia include chronic widespread pain, nonrestorative sleep, fatigue, and morning stiffness. Other associated symptoms include cognitive dysfunction and mood disturbances, including anxiety and depression. Individuals suffering from fibromyalgia struggle with their daily activities, have impaired quality of life, and frequently are disabled.
