Tonix Pharmaceuticals Reports First Quarter 2025 Financial Results and Operational Highlights

FDA PDUFA goal date of August 15, 2025, for TNX-102 SL for the management of fibromyalgia; if approved, TNX-102 SL would become the first new drug for treating fibromyalgia in more than 15 years Announced positive topline results from Phase 1 study of TNX-1500, a next generation anti-CD40L mAb candidate in development for prevention of kidney transplant rejection and treatment of autoimmune disorders Cash and cash equivalents of $131.7 million reported as of March 31, 2025; Current cash sufficient to fund operations into the second quarter of 2026 CHATHAM, N.J., May 12, 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 financial results for the first quarter ended March 31, 2025, and provided an overview of recent operational highlights. “We believe TNX-102 SL (cyclobenzaprine HCl sublingual tablets)* is on track to become a new therapeutic option for patients suffering with fibromyalgia,” said Seth Lederman, M.D., Chief Executive Officer of Tonix. “TNX-102 SL would be the first member of a new class of FDA approved drugs for fibromyalgia. TNX-102 SL is a non-opioid analgesic that targets fibromyalgia’s characteristic disturbed sleep to improve the widespread pain of fibromyalgia, while also being well tolerated. Our focus continues to be on the upcoming U.S. Food and Drug Administration (FDA) Prescription Drug User Fee Act (PDUFA) goal date of August 15, 2025, for a decision on the market authorization on TNX-102 SL for the management of fibromyalgia. We are building out our commercial team for the anticipated product launch in the fourth quarter of this year. Tonix believes it has sufficient cash to fund operations beyond these key milestones.” Dr. Lederman continued, “Beyond TNX-102 SL for fibromyalgia, we are encouraged by the continued achievements in our pipeline, including positive Phase 1 results for TNX-1500, a next generation anti-CD40L Fc-modified humanized monoclonal antibody (mAb) in development for prevention of kidney transplant rejection and pre-clinical results for TNX-801, a live-virus vaccine in development for preventing mpox and smallpox. We look forward to providing additional updates to each of these promising programs in 2025.” Key Investigational Product Candidates* -- Recent Highlights Central Nervous System (CNS) Pipeline TNX-102 SL (cyclobenzaprine HCl sublingual tablets): 5.6 mg, once-daily at bedtime small molecule for the management of fibromyalgia (FM) – a centrally-acting, non-opioid analgesic. In March 2025, Tonix announced that FDA will not require an Advisory Committee meeting to discuss the Company’s New Drug Application (NDA) for TNX-102 SL for the management of fibromyalgia. The FDA previously granted Fast Track designation to TNX-102 SL for the management of fibromyalgia in 2024, a designation intended to expedite FDA review of important new drugs to treat serious conditions and fill an unmet medical need.In December 2024, the NDA for TNX-102 SL for fibromyalgia was accepted by FDA with a PDUFA goal date of August 15, 2025. The NDA was based upon two Phase 3 studies of TNX-102 SL in fibromyalgia that showed statically significant reduction in the chronic, widespread pain associated with fibromyalgia. TNX-102 SL was generally well tolerated and has no known addictive properties. If approved by the FDA, TNX-102 SL would be the first member of a new class of tertiary amine tricyclic (TAT) non-opioid analgesic drugs for fibromyalgia and the first new drug available for treating fibromyalgia in more than 15 years. Fibromyalgia affects more than 10 million adults in the U.S., most of whom are women.In April 2025, Tonix presented data and analyses of TNX-102 SL treatment and effects on fibromyalgia at the American Academy of Pain Medicine (AAPM) 2025 Annual Meeting, held in Austin, Texas, in a poster presentation titled, “Sublingual Cyclobenzaprine (TNX-102 SL) for Fibromyalgia: Efficacy and Safety in Two Randomized, Placebo-Controlled Trials.”In March 2025, the Company presented data and analyses of TNX-102 SL treatment and effects on fibromyalgia at the 7th International Congress on Controversies in Fibromyalgia, held in Vienna, Austria, in an oral presentation titled, “Transmucosal Sublingual Cyclobenzaprine (TNX-102 SL) Treatment of Fibromyalgia at Bedtime to Target Non-Restorative Sleep Showed Durable Pain Reduction in Two Double-Blind Randomized Phase 3 Studies.” TNX-102 SL in development for the treatment of acute stress reaction (ASR) and acute stress disorder (ASD), and prophylaxis against development of posttraumatic stress disorder (PTSD) The U.S. Department of Defense-funded Optimizing Acute Stress Reaction Interventions (OASIS) trial will be conducted by the University of North Carolina under an investigator-initiated investigational new drug (IND) application. The OASIS trial will examine the safety and efficacy of TNX-102 SL to reduce adverse posttraumatic neuropsychiatric sequelae among patients in the emergency department (ED) after a motor vehicle collision. Fourteen days of bedtime TNX-102 SL will be dosed and tested in the immediate aftermath of motor vehicle collision. The study will test the potential for TNX-102 SL to target trauma-related sleep disturbance and its ability to facilitate recovery from ASR and to prevent PTSD. The program has the potential to provide military personnel with a new treatment option that improves warfighter performance and resilience when administered in the early aftermath of traumatic events in the war theater. The study is expected to be initiated in the second quarter of 2025. TNX-1300 (recombinant double mutant cocaine esterase): under investigation for biologic for cocaine intoxication The National Institutes of Health (NIH)'s National Institute of Drug Abuse (NIDA) previously awarded Tonix a Cooperative Agreement grant for approximately $5 million to support development of TNX-1300.TNX-1300 has been granted Breakthrough Therapy designation by the FDA.The Company discontinued enrollment and terminated the Phase 2 CATALYST study of its TNX-1300 double-mutant cocaine esterase 200 mg, i.v. solution product candidate for the treatment of cocaine intoxication because enrollment in this emergency department-based study was slower than projected. The Company is evaluating new study designs and new endpoints for further development of TNX-1300. The CATALYST study was not discontinued for safety or efficacy reasons. Immunology Pipeline TNX-1500 (anti-CD40L Fc-modified humanized monoclonal antibody): third generation anti-CD40L monoclonal antibody under investigation for prophylaxis for organ transplant rejection and treatment of autoimmune disorders. In February 2025, Tonix announced positive topline results from its Phase 1, single ascending dose (SAD) first-in-human trial of TNX-1500 in healthy participants. The objectives of the Phase 1 trial were to assess the safety, tolerability, pharmacokinetics, and pharmacodynamics of intravenous TNX-1500, as well as to support dosing in a planned Phase 2 trial in kidney transplant recipients, pending alignment with the FDA. All objectives were met and support proceeding to a Phase 2 trial. TNX-1500 blocked the primary and secondary antibody responses to a test antigen at the 10 mg/kg and 30 mg/kg i.v. doses, showed mean half-life of 34-38 days for the 10 mg/kg and 30 mg/kg doses (supporting monthly dosing for future efficacy trials) and was generally well-tolerated with a favorable safety profile.The first proposed indication for TNX-1500 is prophylaxis of organ rejection in adult patients receiving a kidney transplant; but multiple additional indications are possible, including the treatment of autoimmune diseases. Preclinical studies have shown that TNX-1500 maintains the activity of first-generation monoclonal antibodies (mAbs), yet with reduced risk of thrombotic complications. Pharmacokinetic data support a monthly i.v. dosing regimen. This analysis together with TNX-1500’s activity and tolerability in animal models, suggests that the protein engineering of TNX-1500’s Fc region has achieved its design goals. Infectious Disease Pipeline TNX-801 (recombinant horsepox virus, minimally replicative live vaccine): potential vaccine to protect against mpox and smallpox. In April 2025, the company presented data on TNX-801 in an oral presentation at the World Vaccine Congress Washington 2025, held in Washington, D.C. The presentation titled “A Novel Single-Dose, Attenuated Live, Minimally Replicative Mpox Vaccine” highlighted positive preclinical efficacy data, demonstrating that TNX-801 protected animals from mpox and rabbitpox and was well tolerated, even in immunocompromised animals. Durable protection of rabbits from lethal rabbitpox infection was present six months after vaccination. In September 2024, Tonix announced that the WHO’s preferred target product profile (TPP), released at the WHO sponsored Mpox Research and Innovation Scientific Conference, aligns with the characteristics of TNX-801. In March 2025, Tonix announced it was awarded a grant from the Medical CBRN Defense Consortium (MCDC) to support the development of TNX-801. The grant will allow Tonix to develop a commercialization plan for TNX-801. Corporate and Partnerships – Recent Highlights* In April 2025, the Company announced it has entered into a collaborative research agreement with Makana Therapeutics, a global leader in the field of xenotransplantation, to study Tonix’s anti-CD40L (CD40 ligand, also called CD154) monoclonal antibody candidate, TNX-1500, in combination with Makana’s human-compatible pig organs and cells for the treatment of organ failure. TNX-1500 is an investigational, humanized Fc-modified IgG4 anti-CD40L antibody with high affinity for CD40L. The preclinical research and development collaboration has the potential to span multiple Makana programs including kidney, heart and islet cell xenotransplant.In April 2025, Tonix announced the launch of TONIX ONE™, a fully-integrated digital platform designed to provide resources to help patients better understand and manage their migraine condition. TONIX ONE provides an intuitive, comprehensive journey for patients by offering educational resources about migraine and the limitations of oral medications which can sometimes lead to delayed or ineffective symptom relief. The platform also connects patients directly to independent migraine specialists via telehealth services and e-prescription requests, simplifying and accelerating access to treatment. During the first quarter of 2025, the Company announced the promotion of Siobhan Fogarty to Chief Technical Officer and the appointment of Gary Ainsworth as its new Vice President, Market Access. Financial - Recent Highlight As of March 31, 2025, Tonix had $131.7 million of cash and cash equivalents, compared to $98.8 million as of December 31, 2024. Net cash used in operations was approximately $16.6 million for first quarter 2025, compared to net cash used in operations of $17.6 for the same period in 2024. On July 30, 2024, the Company entered into a Sales Agreement with AGP pursuant to which the Company may issue and sell, from time to time, shares of the Company’s common stock having an aggregate offering price of up to $250.0 million in at-the-market sales. During the three months ended March 31, 2025, the Company sold approximately 2.7 million shares of common stock for net proceeds of approximately $59.8 million. Subsequent to March 31, 2025, the Company sold 0.6 million shares of common stock under the Sales Agreement, for net proceeds of approximately $9.9 million. The Company believes that its cash resources at March 31, 2025, along with the net proceeds of $9.9 million raised from equity offerings in the second quarter of 2025, will meet its planned operating and capital expenditure requirements into the second quarter of 2026. Subsequent to March 31, 2025, the Company repurchased 150,000 of its shares of common stock outstanding under a share repurchase program, for a gross aggregate cost of approximately $2.9 million. First Quarter 2025 Financial Results Net product revenue for the first quarter 2025 was approximately $2.4 million compared to $2.5 million for the same period in 2024. Net product revenue consisted of combined net sales of Zembrace® SymTouch® and Tosymra®. Cost of Sales for the first quarter 2025 was approximately $0.9 million compared to $1.7 million for the same period in 2024. Research and development expenses for the first quarter 2025 were $7.4 million, compared to $12.9 million for the same period in 2024. This decrease is predominantly due to decreased clinical, non-clinical, manufacturing and employee-related expenses. Selling, general and administrative expenses for the first quarter 2025 were $10.1 million, compared to $9.3 for the same period in 2024. The increase was primarily due to an increase in sales and marketing expenses offset by a decrease in employee-related expenses resulting from a reduction in workforce in earlier 2024. Net loss available to common stockholders was $16.8 million, or $2.84 per share, basic and diluted, for the first quarter 2025, compared to net loss of $14.9 million, or $535.72 per share, basic and diluted, for the same period in 2024. The basic and diluted weighted average common shares outstanding for the first quarter 2025 was 5,927,231 compared to 27,886 shares for the same period in 2024.
