Tonix Pharmaceuticals Announces Selection of Two Contract Manufacturing Organizations for the Launch and Commercial Manufacture of Tonmya for the Management of Fibromyalgia

Tonmya is a potential new first-line, centrally acting non-opioid analgesic for the management of fibromyalgia, supported by positive results from two Phase 3 studies

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

CHATHAM, N.J., March 20, 2024 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a biopharmaceutical company with marketed products and a pipeline of development candidates, today announced it has selected two contract manufacturing organizations (CMOs), one of which is Almac Pharma Services, a member of the privately owned Almac Group, as dual supply sources for the potential launch and commercialization of Tonmya (also known as TNX-102 SL, cyclobenzaprine HCl sublingual tablets) in the U.S.

"Dual sourcing is a critical element for the successful commercial launch and supply chain management of a product," said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. "We are excited to advance our first internally developed program toward NDA submission and to work with two well-established CMOs for commercial supply and potential launch of Tonmya."

"Having supported the development and clinical trial supply of this drug, we're thrilled to be continuing our partnership with Tonix to support the commercial launch and ongoing supply of this important new non-opioid analgesic to patients with fibromyalgia, a chronic debilitating disease," said Mark English, VP Operations, Almac Pharma Services.

Tonmya is a centrally acting, non-opioid medication. As previously announced, Tonix's second positive Phase 3 study, RESILIENT, met its pre-specified primary endpoint, significantly reducing daily pain compared to placebo (p=0.00005) in participants with fibromyalgia. 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. TNX-102 SL was well tolerated with an adverse event profile comparable to prior studies, and no new safety signals were observed.

Tonix plans to submit a New Drug Application (NDA) to the U.S. Food and Drug Administration in the second half of 2024 for Tonmya for the management of fibromyalgia.

About Tonmya* (also known as TNX-102 SL)

TNX-102 SL is a tablet containing 2.8 mg cyclobenzaprine HCl that will be administered sublingually once daily at bedtime for the first 2 weeks, titrating subsequently to 2 tablets (5.6 mg total per day) at bedtime, as tolerated, for chronic, long-term use. The sublingual tablet is formulated using a patented Protectic eutectic formulation including a basifying agent for transmucosal absorption with rapid systemic exposure pharmacokinetic properties suitable for bedtime administration. The eutectic properties enhance the stability with a predicted shelf life of greater than 48 months, at room temperature conditions. The planned commercial distribution will be a 14, 60 and 90 count tablet bottles allowing for titration, flexible and three-month chronic supply. Tonmya is a centrally acting, non-opioid, non-addictive, bedtime medication. In December 2023, the Company announced highly statistically significant and clinically meaningful topline results in RESILIENT, a second positive Phase 3 clinical trial of Tonmya for the management of fibromyalgia. RELIEF, the first positive Phase 3 trial of Tonmya in fibromyalgia, was completed in December 2020. It met its pre-specified primary endpoint of daily pain reduction compared to placebo (p=0.010) and showed activity in key secondary endpoints.

*Tonmya is conditionally accepted by the U.S. Food and Drug Administration (FDA) as the tradename for TNX-102 SL for the management of fibromyalgia. Tonmya has not been approved for any indication.
