• Oral Presentation of Tonmya™ (TNX-102 SL) for Fibromyalgia; NDA preparation in progress
  
• Posters Highlighting Other TNX-102 SL Programs In Clinical Development; Long COVID and Acute Stress Disorder

CHATHAM, N.J., May 22, 2024 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a fully-integrated biopharmaceutical company with marketed products and a pipeline of development candidates, today announced that the Company will deliver an oral presentation and present two posters at the American Society of Clinical Psychopharmacology (ASCP) Annual Meeting being held May 28-31, 2024 at the Loews Miami Beach Hotel in Miami Beach, Fla.

The oral presentation will detail findings of studies of Tonmya (TNX-102 SL, sublingual cyclobenzaprine HCl) in fibromyalgia. One poster will describe the Phase 2 proof of concept study of TNX-102 SL in fibromyalgia-type Long COVID. The second poster will describe the upcoming investigator-initiated Phase 2 trial of TNX-102 SL in treating acute stress disorder and preventing posttraumatic stress disorder after motor vehicle collision, which will be conducted by the University of North Carolina, the sponsor of the study.

TNX-102 SL is a centrally acting, non-opioid medication, which is trade named Tonmya™ for the management of fibromyalgia. As previously announced, the second statistically significant Phase 3 study of Tonmya, RESILIENT, met its pre-specified primary endpoint, significantly reducing daily pain compared to placebo in participants with fibromyalgia (p=0.00005). Statistically significant and clinically meaningful results (p=0.001 or better) were also seen in all key secondary endpoints related to improving sleep quality, reducing fatigue, and improving overall fibromyalgia symptoms and function.

Tonix plans to submit a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) in the second half of 2024 for Tonmya for the management of fibromyalgia and has scheduled a Type B pre-NDA meeting with FDA for the second quarter of 2024.

Copies of the Company’s presentation and posters will be available under the Scientific Presentations tab of the Tonix website at www.tonixpharma.com following the conference. Additional meeting information can be found on the ASCP website here.
