Tonix Pharmaceuticals Further Strengthens Commercial Leadership Team with Appointment of Gary Ainsworth as Vice President of Market Access

Mr. Ainsworth brings over two decades of industry and market access experience to Tonix

U.S. Food and Drug Administration (FDA) recently assigned a Prescription Drug User Fee Act (PDUFA) goal date of August 15, 2025, for U.S. marketing authorization of TNX-102 SL for the management of fibromyalgia

CHATHAM, N.J., January 8, 2025 (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 the appointment of Gary Ainsworth as Vice President, Market Access, effective immediately. Mr. Ainsworth is an accomplished executive with leadership in market access strategies from both large pharmaceutical companies and healthcare consultancies.

“Gary has a significant track record of success building market access functions, developing launch-ready access and reimbursement strategies and payer-focused resources, including those for fibromyalgia and migraine treatment options,” said Thomas Englese, EVP Commercial of Tonix Pharmaceuticals. “His extensive experience will be especially valuable as we work towards the potential approval and commercial launch of TNX-102 SL for the management of fibromyalgia this year.”

Most recently, Mr. Ainsworth was Managing Director, Head of Market Access at Eversana Intouch, where he led the agency function and the efforts to optimize the Company’s vast market access capabilities and services. Prior to that, he was the founder and Managing Director at Havas Gemini, the Market Access Business Unit of Havas Health & You that developed innovative market access strategies and solutions for their clients. Mr. Ainsworth also had a distinguished career leading pharmaceutical organizations’ market access functions. Mr. Ainsworth was the Vice President of Corporate Accounts and Customer Operations for Baxter International within the Anesthesia, Critical Care and Oncology Division where he led a team of national account managers and a patient services telemarketing center. Mr. Ainsworth also led the National Accounts and Managed Care Marketing function at Roche Laboratories and held a variety of market access leadership positions with the predecessor companies to Sanofi. Mr. Ainsworth holds a Master of Business Administration from Rockhurst University and a Bachelor of Arts in Business Administration and a Bachelor of Arts in Public Relations from William Jewell College.

“Joining the Tonix team presents an exciting and fulfilling opportunity to help advance a treatment for the millions of individuals with fibromyalgia,” said Mr. Ainsworth. “I look forward to providing additional expertise to a seasoned leadership team with the goal of bringing meaningful therapeutics to patients in need.”

At the end of December 2024, Tonix announced that the U.S. Food and Drug Administration (FDA) assigned a Prescription Drug User Fee Act (PDUFA) goal date of August 15, 2025, for a decision on marketing authorization for TNX-102 SL (cyclobenzaprine HCl sublingual tablets) for fibromyalgia. TNX-102 SL is a non-opioid, centrally-acting analgesic. Fibromyalgia is a common chronic pain condition that affects mostly women.

Tonix Pharmaceuticals Holding Corp.^*

Tonix is a fully integrated biopharmaceutical company focused on transforming therapies for pain management and vaccines for public health challenges. Tonix’s development portfolio is focused on central nervous system (CNS) disorders. Tonix’s priority is to advance TNX-102 SL, a product candidate for the management of fibromyalgia, for which an NDA was submitted based on two statistically significant Phase 3 studies for the management of fibromyalgia and for which a PDUFA (Prescription Drug User Fee act) goal date of August 15, 2025 has been assigned for a decision on marketing authorization. The FDA has previously granted Fast Track designation to TNX-102 SL for the management of fibromyalgia. TNX-102 SL is also being developed to treat acute stress reaction and acute stress disorder under a Physician-Initiated IND at the University of North Carolina in the OASIS study funded by the U.S. Department of Defense (DoD). Tonix’s CNS portfolio includes TNX-1300 (cocaine esterase), a biologic in Phase 2 development designed to treat cocaine intoxication that has FDA Breakthrough Therapy designation, and its development is supported by a grant from the U.S. National Institute of Drug Abuse and Addiction. Tonix’s immunology development portfolio consists of biologics to address organ transplant rejection, autoimmunity and cancer, including TNX-1500, which is an Fc-modified humanized monoclonal antibody targeting CD40-ligand (CD40L or CD154) being developed for the prevention of allograft rejection and for the treatment of autoimmune diseases. Tonix also has product candidates in development in the areas of rare disease, including TNX-2900 for Prader-Willi syndrome, and infectious disease, including a vaccine for mpox, TNX-801. In July 2024, Tonix announced a contract with the U.S. DoD’s Defense Threat Reduction Agency (DTRA) for up to $34 million over five years to develop TNX-4200, small molecule broad-spectrum antiviral agents targeting CD45 for the prevention or treatment of infections to improve the medical readiness of military personnel in biological threat environments. Tonix owns and operates a state-of-the art infectious disease research facility in Frederick, Md. Tonix Medicines, our commercial subsidiary, markets Zembrace® SymTouch® (sumatriptan injection) 3 mg and Tosymra® (sumatriptan nasal spray) 10 mg for the treatment of acute migraine with or without aura in adults.

* Tonix’s product development candidates are investigational new drugs or biologics; their efficacy and safety have not been established and have not been approved for any indication.

The development of novel smallpox vaccines using multi - vaccine platforms (i.e., use common vaccine vectors, manufacturing ingredients, and processes) would improve the capacity for rapid vaccine production in response to a smallpox event and reduce the need for stockpiling in the SNS at current levels. ‒ “Given the lack of commercially available orthopoxvirus diagnostics, vaccines, and therapeutics, planning for logistics and supply chain management considerations is critical. Efforts could give consideration to developing plans to increase the number of smallpox vaccine and therapeutics manufacturers as well as optimizing current manufacturing capacities should they be needed in the shorter term.” 1 Office of Science and Technology Policy (OSTP).
