TNX-102 SL is a sublingual formulation of cyclobenzaprine designed for transmucosal delivery and durable activity in treating fibromyalgia: FDA PDUFA goal date of August 15, 2025 TNX-102 SL demonstrated statistically significant improvement in the primary endpoint of reduction in fibromyalgia pain in two double-blind randomized placebo-controlled Phase 3 studies If approved by FDA, TNX-102 SL would become the first member of a new class of non-opioid analgesic drugs for fibromyalgia and the first new drug for treating fibromyalgia in more than 15 years CHATHAM, N.J., June 16, 2025 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company) presented data in a poster presentation at the Annual European Congress of Rheumatology (EULAR) 2025, held June 11-14, 2025, in Barcelona, Spain. A copy of the Company’s poster, titled “Advancing Fibromyalgia Treatment: Transmucosal Sublingual Cyclobenzaprine (TNX-102 SL) Targets Non-restorative Sleep and Provides Sustained Pain Reduction” is available under the Scientific Presentations tab of the Tonix website at www.tonixpharma.com . TNX-102 SL (cyclobenzaprine HCl sublingual tablets) is a non-opioid analgesic designed for daily bedtime dosing with an FDA Prescription Drug User Fee Act (PDUFA) goal date of August 15, 2025. “Fibromyalgia is a complex and invisible chronic pain condition which drives many patients to be prescribed chronic opioids which are associated with addiction and overdose,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “To address the chronic symptoms of fibromyalgia, potential therapeutic options must provide durable benefits. TNX-102 SL has shown statistically significant, durable activity (14 weeks) in reducing fibromyalgia pain in two Phase 3 studies. Designed to target the sleep disturbance of fibromyalgia, TNX-102 SL harnesses the therapeutic activity of cyclobenzaprine in part by reducing in the level of the active metabolite norcyclobenzaprine relative to oral cyclobenzaprine. Norcyclobenzaprine is believed to interfere with the durability of oral cyclobenzaprine’s treatment effect in off-label chronic dosing regimens and in a failed double-blind randomized placebo-controlled trial. 1 TNX-102 SL now has the potential to be the first new treatment option for fibromyalgia patients in 15 years.” TNX-102 SL is designed for transmucosal absorption to bypass first-pass hepatic metabolism. The poster presentation shows the day 20 steady state blood levels from a study of nightly TNX-102 SL dosing in which the peak level of cyclobenzaprine exceeds the level of the active metabolite norcyclobenzaprine during sleep time. In contrast, with nightly oral cyclobenzaprine dosing, pharmacokinetic simulations show that norcyclobenzaprine accumulates to higher levels, and the cyclobenzaprine peak level does not exceed the norcyclobenzaprine level during sleep time. The poster includes data from the RESILIENT Phase 3 study evaluating the efficacy and safety of TNX-102 SL with a primary endpoint of reducing daily pain numeric rating scale scores after 14 weeks of treatment. TNX-102 SL significantly reduced pain and improved clinical outcomes in fibromyalgia patients while demonstrating a favorable tolerability profile. TNX-102 SL employs a novel mechanism targeting the sleep disturbance in fibromyalgia by acting as a potent antagonist at four post-synaptic receptors, each of which is known to regulate sleep. About Fibromyalgia Fibromyalgia is a common chronic pain disorder that is understood to result from amplified sensory and pain signaling within the central nervous system, called central sensitization. Brain imaging studies have localized the functional disorder to the brain’s insula and anterior cingulate cortex. Fibromyalgia afflicts more than 10 million adults in the U.S., the majority of whom are women. Symptoms of fibromyalgia include chronic widespread pain, non-restorative sleep, fatigue, and brain fog (or cognitive dysfunction). Other associated symptoms include mood disturbances, including depression, anxiety, headaches and abdominal pain or cramps. Individuals suffering from fibromyalgia often struggle with their daily activities, have impaired quality of life, and frequently are disabled. Physicians and patients report common dissatisfaction with currently marketed products. Fibromyalgia is now recognized as the prototypic nociplastic syndrome. Nociplastic pain is the third primary type of pain in addition to nociceptive pain and neuropathic pain. Many patients present with pain syndromes that are mixtures of the three primary types of pain. Nociplastic syndromes are associated with central and peripheral sensitization. Fibromyalgia can occur without any identifiable precipitating event. However, many fibromyalgia cases follow one or more precipitating event(s) including: post-operative pain, acute or chronic nociceptive or neuropathic pain states; recovery from an infectious illness; a cancer diagnosis or cancer treatment; a metabolic or endocrine stress; or a traumatic event. In the cases of recovery from an infectious illness, fibromyalgia is considered an Infection-Associated Chronic Condition. In addition to fibromyalgia cases associated with other conditions or stressors, the U.S. National Academies of Sciences, Engineering, and Medicine, has concluded that fibromyalgia is a diagnosable condition that can occur after recovery from COVID-19 in the context of Long COVID. About TNX-102 SL TNX-102 SL is a centrally acting, non-opioid investigational drug, designed for chronic use. The tablet is a patented sublingual formulation of cyclobenzaprine hydrochloride developed for bedtime dosing for the management of fibromyalgia. Cyclobenzaprine potently binds and acts as an antagonist at four different post-synaptic neuroreceptor subtypes: serotonergic-5-HT 2A , adrenergic-α 1 , histaminergic-H 1 , and muscarinic-M 1 -cholinergic receptors. Together, these interactions are believed to target the non-restorative sleep characteristic of fibromyalgia identified by Professor Harvey Moldofsky in 1975. Cyclobenzaprine is not associated with risk of addiction or dependence. The TNX-102 SL tablet is based on a eutectic formulation of cyclobenzaprine HCl and mannitol that provides a stable product which dissolves rapidly and delivers cyclobenzaprine by the transmucosal route efficiently into the bloodstream. The eutectic protects cyclobenzaprine HCl from interacting with the basifying agent that is also part of the formulation and required for efficient transmucosal absorption. Patents based on TNX-102 SL’s eutectic composition and its properties have issued in the U.S., E.U., Japan, China and many other jurisdictions around the world and provide market protection into 2034. The European Patent Office’s Opposition Division maintained Tonix’s European Patent EP 2 968 992 in unamended form after an Opposition was filed against it by a Sandoz subsidiary, Hexal AG. Hexal AG did not appeal that decision. The formulation of TNX-102 SL was designed specifically for sublingual administration and transmucosal absorption for bedtime dosing to target disturbed sleep, while reducing the risk of daytime somnolence. Clinical pharmacokinetic studies indicated that relative to oral cyclobenzaprine, TNX-102 SL results in higher levels of exposure during the first 2 hours after dosing and in deceased levels of the long-lived active metabolite, norcyclobenzaprine in both single dose and multiple dose studies, consistent with bypassing first pass hepatic metabolism. Cyclobenzaprine is a tertiary amine tricyclic and its active metabolite norcyclobenzaprine is a secondary amine tricyclic. At steady state after 20 days of dosing TNX-102 SL, the dynamic peak level of cyclobenzaprine is higher than the background level of norcyclobenzaprine during sleep time. In contrast, after 20 days of dosing oral cyclobenzaprine, the simulated peak level of cyclobenzaprine is lower than the simulated background level of norcyclobenzaprine.
