New Drug Application (NDA) submission to the FDA on track for the second half of 2024

CHATHAM, N.J., June 17, 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, presented data from a poster presentation at the Annual European Congress of Rheumatology (EULAR) 2024, held June 12-15, 2024 at the Messe Wien Congress Center in Vienna, Austria. A copy of the Company’s poster presentation is available under the Scientific Presentations tab of the Tonix website at www.tonixpharma.com.

In the poster presentation titled, “Targeting Non-Restorative Sleep in Fibromyalgia with Bedtime TNX-102 SL (Sublingual Cyclobenzaprine HCl) Significantly Improves Pain in RESILIENT, a Confirmatory Phase 3 Randomized Clinical Trial”, Tonyma met the pre-specified primary endpoint in the Phase 3 RESILIENT trial, significantly reducing daily pain compared to placebo (p-value=0.00005) in participants with fibromyalgia while also demonstrating broad syndromal improvement. Tonmya demonstrated statistically significant improvement in all six pre-specified key secondary endpoints including those related to improving sleep quality, reducing fatigue, and improving patient global ratings and overall fibromyalgia symptoms and function. Tonmya was well tolerated with an adverse event (AE) profile comparable to prior studies and no new safety signals observed.

In pre-specified exploratory analyses, Tonmya treatment also improved depressive symptoms measured by the Beck Depression Inventory and improved female sexual function by the Changes in Sexual Function Questionnaire in the RESILIENT trial.

“People suffering with fibromyalgia tend to struggle with daily activities, have impaired quality of life and are frequently disabled^”, said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “We believe the activity of Tonmya on pain, sleep quality, fatigue cognitive dysfunction, and depression are indicative of the broad-spectrum activity of Tonmya, suggesting Tonmya treats fibromyalgia at a syndromal level. We are excited by the prospect of offering this patient population its potential first new therapy option in more than a decade.”

Tonix remains on track to submit an NDA to the U.S. Food and Drug Administration (FDA) in the second half of 2024 for Tonmya for the management of fibromyalgia.
