FDA is expected to assign a Prescription Drug User Fee Act (PDUFA) target action date and announce whether Priority Review has been granted in the Day 74 Letter

TNX-102 SL is a non-opioid, centrally acting analgesic, granted Fast Track designation by FDA

Fibromyalgia affects more than 10 million adults in the U.S. who are mostly women

TNX-102 SL has the potential to be the first member of a new class of analgesic drugs for fibromyalgia and the first new drug for treating fibromyalgia in more than 15 years, if approved by FDA

NDA based on two statistically significant Phase 3 studies of TNX-102 SL for the management of fibromyalgia; in which TNX-102 SL was generally well tolerated

CHATHAM, N.J., Dec. 17, 2024 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), today announced that the U.S. Food and Drug Administration (FDA) has accepted the filing of its New Drug Application (NDA) for TNX-102 SL (cyclobenzaprine HCl sublingual tablets), a 5.6 mg, non-opioid, centrally-acting analgesic, for the management of fibromyalgia. The FDA is expected to assign the NDA a Prescription Drug User Fee Act (PDUFA) target action date in a Day 74 Letter. At that time, the FDA will also communicate to Tonix whether Priority Review has been granted. TNX-102 SL was granted Fast Track designation for fibromyalgia by the FDA in July of 2024. Fast Track is designed to expedite FDA review of important new drugs to treat serious conditions and fill an unmet medical need.

“The FDA’s acceptance of our NDA represents another step forward as we pursue our goal of delivering the first member of a new class of medicines for the management of fibromyalgia, a condition affecting over 10 million adults in the U.S.,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “The fibromyalgia community, comprised of patients and their families and support groups, has been waiting for a new drug for over 15 years. Analysis of insurance claims in the U.S., commissioned by Tonix, have shown that 18 months after diagnosis, fibromyalgia patients were more likely to be prescribed addictive opioids than all three of the FDA-approved drugs combined.”

Dr. Lederman continued, “We look forward to working closely with the FDA throughout the NDA review period with the goal of bringing TNX-102 SL to the market to address the significant unmet needs of the fibromyalgia community as quickly as possible. Furthermore, this is an important milestone as we advance our commercial preparations in anticipation of a potential approval in 2025 with an accomplished commercial leadership team already in place, supporting our marketed products 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.”

The NDA is supported by data from two 14-week double-blind, randomized, placebo-controlled Phase 3 clinical trials evaluating the safety and efficacy of TNX-102 SL as a bedtime treatment for fibromyalgia. The first Phase 3 trial, RELIEF, of TNX-102 SL 5.6 mg in fibromyalgia, completed in December 2020, met its pre-specified primary endpoint of significantly reducing daily pain compared to placebo (p=0.010). In the confirmatory Phase 3 RESILIENT study in fibromyalgia, completed in December 2023, TNX-102 SL again met the pre-specified primary endpoint of significantly reducing daily pain compared to placebo (p =0.00005). In both trials, TNX-102 SL was generally well tolerated with an adverse event profile comparable to prior studies and with no new safety signals observed. In both pivotal studies, the most common treatment-emergent adverse event was tongue or mouth numbness at the administration site, which was temporally related to dosing, self-limited, never rated as severe, and rarely led to study discontinuation (one participant in each study). Excluding COVID-19, systemic adverse events in each of the two studies was lower than 4.0%. Tonix believes the submitted dossier contains the requisite safety and efficacy data from two adequate and well-controlled studies to support NDA approval.

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 a spectrum of 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. Fibromyalgia is also recognized as a Chronic Overlapping Pain Condition, which is a group of related conditions including, chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME), irritable bowel syndrome, endometriosis, low back pain, post-concussive syndrome (also known as mild traumatic brain injury), chronic Lyme Disease, chronic diabetic neuropathy and chronic post-herpetic neuralgia.

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-α₁, histaminergic-H₁, and muscarinic-M₁-cholinergic receptors. Together, these interactions are believed to target the non-restorative sleep characteristic of fibromyalgia that was 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. 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. In contrast, after 20 days of dosing oral cyclobenzaprine, the simulated peak level of cyclobenzaprine is lower than the simulated background level of norcyclobenzaprine.

Key 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 October 2024, Tonix announced submission of the TNX-102 SL New Drug Application (NDA) for fibromyalgia to the FDA. The submission 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. If approved by the FDA, TNX-102 SL would be the first member of a new class of 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 September 2024, at the 11th Global Conference on Pharmaceutics and Novel Drug Delivery Systems (PDDS 2024), the Company announced data highlighting the proprietary formulation technology and pharmacokinetic properties of TNX-102 SL, including composition and methods patents based on the proprietary eutectic¹ formulation of TNX-102 SL that are expected to provide market exclusivity until at least 2034 in the U.S., EU, Japan, China and other jurisdictions. The eutectic protects cyclobenzaprine HCl from interacting with the basifying agent that is also part of the formulation and required for efficient transmucosal absorption. The formulation of TNX-102 SL was designed specifically for sublingual administration and transmucosal absorption for bedtime dosing to target disturbed sleep, improve pain and other fibromyalgia symptoms, while reducing the risk of daytime somnolence.
• In August 2024, at both the DoD’s 2024 Military Health System Research Symposium (MHSRS), and at the International Association for the Study of Pain’s (IASP’s) 2024 World Congress on Pain, Tonix announced additional data and analyses of TNX-102 SL for the management of fibromyalgia. TNX-102 SL had met the pre-specified primary endpoint in the Phase 3 RESILIENT study, significantly reducing daily pain compared to placebo (p-value=0.00005) in participants with fibromyalgia while demonstrating broad syndromal benefits with 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. TNX-102 SL was well tolerated with an adverse event profile comparable to prior studies and no new safety signals were observed.
• In July 2024, Tonix noted that, based on the new definition of Long COVID by the U.S. National Academies of Sciences, Engineering and Medicine (NASEM), fibromyalgia is a ‘diagnosable condition’ in people suffering from Long COVID. The Company believes that diagnosing fibromyalgia in Long COVID patients will increase the potential market for TNX-102 SL following approval as compared to market estimates from before the COVID-19 pandemic.

TNX-102 SL for the treatment of acute stress reaction (ASR) and acute stress disorder (ASD), and prophylaxis against development of posttraumatic stress disorder (PTSD)

• In August 2024 at the DoD’s MHSRS conference, the Company presented clinical data and rationale supporting the potential for TNX-102 SL to be studied for the treatment of ASR and prevention of PTSD. Prior studies showed that treatment with TNX-102 SL showed effects on sleep and PTSD symptoms in PTSD patients at two and four weeks¹. This supportive data on the effects of TNX-102 SL on reducing PTSD symptoms suggest early intervention immediately after trauma using TNX-102 SL has the potential to reduce ASR/ASD symptoms which are similar to those of PTSD^2,3. Data from these trials support testing of TNX-102 SL within 24 hours of index trauma for effects on ASR symptoms and the subsequent incidence of PTSD.
• The DoD-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 results may ultimately provide military personnel with a new treatment option that, when administered in the early aftermath of a traumatic event to individuals with ASR symptoms, improves warfighter function.

TNX-1300 (recombinant double mutant cocaine esterase): biologic for life-threatening cocaine intoxication

• Tonix announced the first patient in the Phase 2 CATALYST study of TNX-1300 for the treatment of cocaine intoxication was enrolled in August 2024. CATALYST is a Phase 2 single-blind, placebo-controlled, proof-of-concept study in patients presenting to the emergency department. Topline results are expected in the first half of 2025.
• The National Institutes of Health (NIH)’s National Institute of Drug Abuse (NIDA) previously awarded Tonix a Cooperative Agreement grant for approximately $5 million from to support development of TNX-1300.
• TNX-1300 has been granted Breakthrough Therapy designation by the FDA.

Infectious Disease Pipeline

TNX-801 (recombinant horsepox virus, live vaccine): potential vaccine to protect against mpox disease and smallpox.

• In September 2024, at the DoD’s MHSRS conference and in October 2024 at the World Vaccine Congress in Barcelona, Spain, Tonix presented new data on potential mpox vaccine, TNX-801, demonstrating tolerability and no evidence of spreading to blood or tissues, even at high doses, in immunocompromised animals. TNX-801 is an attenuated live-virus vaccine based on synthesized horsepox that has been shown to provide single-dose immune protection against a monkeypox challenge. After a single-dose vaccination, TNX-801 prevented clinical disease and lesions, and also decreased shedding in the mouth and lungs of non-human primates after a lethal challenge with Clade Ia monkeypox. These findings are consistent with TNX-801 inducing mucosal immunity and suggest TNX-801 has the ability to block forward transmission.
• In August 2024, the WHO determined that the upsurge of mpox in a growing number of countries in Africa constitutes a public health emergency of international concern (PHEIC), the second such declaration in the past two years in response to transmission of the virus. Mpox cases of the new clade 1b mpox have since also been detected in Sweden, Thailand, Singapore, India, Germany and England.
• In September 2024, the Company announced that the WHO’s preferred TPP aligns with the characteristics of TNX-801. Key elements of the WHO draft TPP include single-dose, durable protection, administration without special equipment, and stability at ambient temperature. Other potential beneficial characteristics include the ability to limit forward transmission, use in case-contact vaccination strategies and suitability for use in immunocompromised individuals.

World Health Organization declared spread of mpox in multiple African countries a public health emergency of international concern (PHEIC) for the second time in two years

Worldwide availability and affordability of single-dose mpox vaccine with durable protection will be required to address global health emergency

The newest Clade 1 strain represents a new global threat with mortality up to 10%

Bilthoven Biologicals to develop manufacturing processes in preparation for potential GMP manufacturing

CHATHAM, N.J., Aug. 26, 2024 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix), a fully-integrated biopharmaceutical company with marketed products and a pipeline of development candidates, and Bilthoven Biologicals (BBio), part of the world’s largest vaccine manufacturer the Cyrus Poonawalla Group, which includes the Serum Institute of India, today announced a collaboration to advance TNX-801, Tonix’s mpox vaccine candidate. TNX-801 (recombinant horsepox virus) is a live replicating, attenuated virus vaccine based on horsepox in preclinical development to prevent mpox and smallpox.

TNX-801 is based on technology that has the potential to be used as a viral vector platform from which recombinant versions can be developed to protect against other infectious diseases. BBio is a global vaccine company, producing prophylactic vaccines as well as vaccines for therapeutic use. BBio has been selected by the European Union for its pandemic preparedness program of ‘ever warm’ vaccine manufacturing companies.

TNX-801 has demonstrated in animal models to provide immune protection with better tolerability than vaccines based on 20^th century vaccinia viruses. Preclinical studies have shown positive efficacy data, demonstrating that TNX-801 protected non-human primates against lethal challenge with intratracheal Clade 1 monkeypox virus. After a single dose vaccination, TNX-801 prevented clinical disease and lesions and decreased shedding in the mouth and lungs of non-human primates. These findings are consistent with mucosal immunity and suggest the ability to block forward transmission.

On August 14, 2024, the World Health Organization (WHO) determined that the upsurge of mpox in a growing number of countries in Africa constitutes a public health emergency of international concern, the second such declaration in the past two years called in response to an mpox outbreak. The current outbreak was caused by Clade 1 monkeypox virus, while the 2022 outbreak was caused by Clade 2 monkeypox virus. The global mpox outbreak from Clade 2, which commenced in 2022, has affected over 90,000 persons in countries where mpox had previously not been endemic, including Europe and the U.S. The spread of Clade 2b mpox in 2022 underscores the pandemic potential of the disease. In several Central African countries, including the Democratic Republic of the Congo, mpox is currently endemic, with the Clade 1 showing a mortality rate of up to 10%.

“The recent mpox outbreak exemplifies precisely why we built the pandemic preparedness facility at BBio,” said Jurgen Kwik, Chief Executive Officer of Bilthoven Biologicals. “The establishment of the ‘ever-warm’ facility for pandemic preparedness underscores the critical importance of readiness in the face of global health emergencies, such as mpox. This collaboration encapsulates the essential role of the facility in bolstering pandemic preparedness and response capabilities.”

“We look forward to collaborating with BBio and to accelerating the development of our vaccine candidate to prevent mpox,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “TNX-801 is administered with a single dose, which we believe will improve acceptance and eliminate partial vaccination compared to the current two-dose regimens. We believe TNX-801 can be rapidly scaled up for manufacturing and can be distributed and stored without a costly and cumbersome ultra-cold supply chain. TNX-801 has the potential to make a global impact on mpox and the risk of smallpox because of its durable T-cell immune response, the potential to manufacture at scale, and the use of a lower dose than non-replicating vaccines.”

Dr. Lederman added, “The worldwide availability of an affordable, safe and effective single dose mpox vaccine is essential given the pandemic potential of the disease. Successful development of TNX-801 will establish the foundation for potentially expanding the viral vector platform, for which recombinant versions can be developed to protect against other infectious diseases and future outbreaks. Our TNX-1800 vaccine (recombinant horsepox virus expressing SARS-CoV-2 spike) in development to protect against COVID-19 was selected by the U.S. National Institutes of Health for Project NextGen.”

About TNX-801
TNX-801 (recombinant horsepox virus) is a live virus vaccine based on horsepox in pre-clinical development to prevent mpox and smallpox. Tonix reported positive preclinical efficacy data, demonstrating that TNX-801 vaccination protected non-human primates against lethal challenge with monkeypox.¹ Tonix has received official written response from a Type B pre-Investigational New Drug Application (IND) meeting with the U.S. Food and Drug Administration (FDA) to develop TNX-801 as a potential vaccine to protect against mpox disease and smallpox.² Tonix believes the FDA feedback provides a path to agreement on the design of a Phase 1 /2 study and the overall clinical development plan. More than 90,000 people contracted mpox globally. during the 2022-23 epidemic.³ The June 2023 cluster of mpox in Chicago revealed breakthrough cases of the disease in individuals who had been vaccinated with the currently authorized non-replicating vaccine, which is administered in two doses.⁴ In contrast, TNX-801 is delivered percutaneously with only one dose and therefore may achieve higher rates of community protection by eliminating drop-out between doses and limiting forward transmission. Moreover, relying on only one approved mpox vaccine at present is a risk for the global supply chain that has already led to insufficient availability of vaccines to meet global health needs, especially in Africa. TNX-801 has the potential to make a global impact on mpox and the risk of smallpox because of its durable T-cell immune response, the potential to manufacture at scale, and the use of a lower dose than non-replicating vaccines.
