First payment received under Tonix’s contract with the Defense Threat Reduction Agency (DTRA), for up to $34 million over five years
CHATHAM, N.J., Oct. 17, 2024 (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, received its first payment from the Defense Threat Reduction Agency (DTRA), an agency within the U.S. Department of Defense (DoD), to develop small molecule broad-spectrum antiviral agents for the prevention or treatment of infections to improve the medical readiness of military personnel in biological threat environments. The previously announced award from DTRA is for up to $34 million over five years.
“This award provides important validation and substantial non-dilutive funding for our ongoing research to advance our antiviral discovery program,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals “With biological adaptations and mutations happening to viruses rapidly across the globe, this research will be crucial in order to protect lives in the event biological threats are introduced onto the battlefield.”
The $34.0 million five-year contract will help fund and accelerate the development of the Company’s broad-spectrum antiviral program, which has the potential to reduce viral load and allow the adaptive immune system to alert the other arms of the immune system to mount a protective response. Tonix plans to leverage previous research on phosphatase inhibitors, specifically compounds that target CD45, to optimize lead compounds for therapeutic intervention of biothreat agents and provide the government with a complete and cost-effective solution for a broad-spectrum medical countermeasure. Tonix’s premise is that partial inhibition of CD45 will provide optimal antiviral protection while requiring lower plasma drug concentrations, a lower dose, and a better safety profile.
Tonix will utilize its state-of-the-art research laboratory capabilities, including a Biosafety Level 3 (BSL-3) lab at its research and development center (RDC) facility located in Frederick, Md., as well as experienced personnel in-house. The RDC is located in Maryland’s ‘I-270 biotech corridor’ and is close to the center of the U.S. biodefense research community.

NDA based on two Phase 3 studies of TNX-102 SL in fibromyalgia with statistically significant results on the primary endpoint of reducing widespread pain; generally well tolerated
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
If approved by FDA, TNX-102 SL would 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
CHATHAM, N.J., Oct. 16, 2024 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), today announced the submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for TNX-102 SL (cyclobenzaprine HCl sublingual tablets) 5.6 mg, a non-opioid, centrally-acting analgesic that showed statistically significant reduction in the chronic, widespread pain associated with fibromyalgia in two Phase 3 studies and was generally well tolerated. 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.
“With the submission of this NDA, Tonix has achieved a critical milestone in potentially bringing a new first-line treatment option to the large and dissatisfied fibromyalgia population that has not had a new pharmacotherapy in over 15 years,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “TNX-102 SL would be the first member of a new class of medicines for treating fibromyalgia. TNX-102 SL was designed and developed as a bedtime treatment to be taken daily on a chronic basis. Tonix believes bedtime TNX-102 SL relieves fibromyalgia pain by targeting the non-restorative sleep that is characteristic of fibromyalgia.”
The NDA submission 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 5.6 mg as a bedtime treatment for fibromyalgia. The prior Phase 3 RELIEF trial of TNX-102 SL 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 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). Therefore, Tonix believes the submitted dossier contains the requisite safety and efficacy data from two adequate and well-controlled studies to support NDA submission.
“Despite three FDA-approved medications, representing two different classes of medicines, there remains a need for new treatment options for fibromyalgia patients,” commented Gregory Sullivan, M.D., Chief Medical Officer of Tonix Pharmaceuticals. “If approved by FDA, TNX-102 SL would be the first of a new tricyclic class of medicines for treating fibromyalgia. The existing FDA-approved drugs for fibromyalgia include the gabapentinoid class, represented by Pfizer’s Lyrica® (pregabalin) approved in 2008, and the SNRI class, represented by Lilly’s Cymbalta® (duloxetine) and AbbVie’s Savella® (milnacipran) approved in 2007 and 2009, respectively. The TNX-102 SL tablet is based on a proprietary eutectic formulation of cyclobenzaprine HCl and mannitol that provides a stable product which dissolves rapidly and efficiently delivers cyclobenzaprine by the transmucosal route into the bloodstream. I would like to thank all the participants in our clinical trials, as well as the trial investigators and staff, who worked together over many years to help make this important milestone possible.”
The FDA typically has a 60-day filing review period to determine whether the submitted NDA is complete and accepted for review. If FDA accepts the NDA for review, the Company expects a 2025 date for an FDA decision on approval, based on the Prescription Drug User Fee Act (PDUFA).
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 insular 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: 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 occurs after recovery from COVID-19 in the context of Long COVID. Fibromyalgia is also recognized as a Chronic Overlapping Pain Condition, due to shared symptoms with 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 bedtime 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 interacts as an antagonist at four different receptors in the brain: serotonergic-5-HT2A, 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 formation 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 the addition of a basifying agent was necessary for efficient transmucosal absorption which 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.

We Expect The NDA Filing For Tonmya Approval To Be Submitted Shortly. We anticipate the NDA submission for Tonmya to be announced around the end of October 2024. This would start the FDA review process, which we expect to lead to marketing approval in mid-2025. In July, Tonmya received Fast Track Review, a designation that gives advantages in the regulatory pathway. With a pending NDA submission for a drug that could be used by millions of patients, we believe the company’s progress has not been reflected in the stock price.
Fast Track Review Is A Significant Distinction. The Fast Track Review designation from the FDA is awarded to drugs that can make significant impact on serious medical conditions. The designation provides important benefits including increased communications with the FDA, as well as eligibility for Accelerated Approval and Priority Review. We expect the application for Accelerated Approval to be filed shortly after the NDA is completed. This could shorten the FDA’s review period by up to 4 months.

New patent expected to provide market exclusivity into 2036
Zembrace® SymTouch® (sumatriptan succinate injection) 10mg is indicated for the acute treatment of migraine in adults
CHATHAM, N.J., Sept. 27, 2024 (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 that the United States Patent and Trademark Office issued U.S. Patent No. 12,097,183 to the Company on September 24, 2024. The patent, entitled “Pharmaceutical Composition for Treating Migraine”, claims use of a pre-filled autoinjector comprising a composition of Zembrace® SymTouch® for treating migraines via subcutaneous administration. This patent, excluding possible patent term extensions, is expected to provide protection into 2036.
“We are excited to announce the issuance of this additional patent, providing additional protection for our exclusive marketing and sale of FDA-approved Zembrace® for the treatment of migraines,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “We believe Zembrace® is a compelling non-oral option for people who suffer with migraines.”
Tonix recently launched a new educational campaign, “Does Your Migraine Pill Work Every Time?” The goal of the campaign is to educate patients and their healthcare providers on the benefits of non-oral migraine medications including nasal and injectable treatment options. Non-oral migraine medications, such as injectables and nasal sprays, do not rely on the digestive system to be absorbed and can offer the potential for faster relief from migraine symptoms in as little as 10 minutes.
Migraine often requires patients to advocate for themselves to develop an effective migraine treatment plan. Empowering patients to understand why they are experiencing delayed or inconsistent relief from oral medications and educating them on other migraine treatment options could ultimately improve their management of migraine symptoms and ultimately enhance their quality of life.
For example, gastroparesis is common before, during, and sometimes in between migraine attacks. Gastroparesis can slow or even block the absorption of oral medications causing delayed, incomplete, or no migraine symptom relief. Tonix will launch a new disease education website, www.gpmigraine.com, for patients who want to learn more about gastroparesis and migraine and why their oral medications do not work.
Dr. Lederman continued, “Tonix is dedicated to educating patients and their healthcare providers on gastroparesis and how non-oral medicines including nasal and injectable medications can help patients manage their migraines. We hope to inspire patients to optimize their migraine treatment plan with non-oral medications.”
About Migraine
Nearly 40 million people in the United States suffer from migraine1 and it has been recognized as the second leading cause of disability in the world2,3. Migraine is characterized by debilitating attacks lasting four to 72 hours with multiple symptoms, including pulsating headaches of moderate to severe pain intensity often associated with nausea or vomiting, and/or sensitivity to sound (phonophobia) and sensitivity to light (photophobia)4.

Concurrent or recent (within 2 weeks) use of a MAO-A inhibitor
Hypersensitivity to sumatriptan (angioedema and anaphylaxis seen)
Severe hepatic impairment
WARNINGS AND PRECAUTIONS
Myocardial ischemia/infarction, Prinzmetal’s angina: These events may occur even in patients without known cardiovascular disease. Perform cardiac evaluation in triptan-naïve patients with multiple risk factors and, if satisfactory, administer first dose of ZEMBRACE SymTouch and TOSYMRA in a medically-supervised setting
Arrhythmias: Life-threatening disturbances of cardiac rhythm, including ventricular tachycardia and ventricular fibrillation leading to death, have been reported within a few hours following the administration of 5-HT1 agonists. Discontinue ZEMBRACE SymTouch and TOSYMRA if these disturbances occur
Sensations of chest/throat/neck/jaw pain, tightness, pressure, or heaviness: Commonly occur after treatment with 5-HT1 agonists and are usually non-cardiac in origin. Perform a cardiac evaluation in patients with cardiac risk
Cerebrovascular Events: Cerebral hemorrhage, subarachnoid hemorrhage, and stroke have occurred in patients treated with 5-HT1 agonists, and some have resulted in fatalities. Discontinue ZEMBRACE SymTouch and TOSYMRA if a cerebrovascular event occurs. Before treating headaches in patients not previously diagnosed as migraineurs, and in migraineurs who present with atypical symptoms, exclude other potentially serious neurological conditions
Other Vasospasm Reactions: 5-HT1 agonists, including ZEMBRACE SymTouch and TOSYMRA, may cause non-coronary vasospastic reactions, such as peripheral vascular ischemia, gastrointestinal vascular ischemia and infarction, splenic infarction, and Raynaud’s syndrome. In patients who experience symptoms or signs suggestive of a vasospastic reaction following the use of any 5-HT1 agonist, rule out a vasospastic reaction before using ZEMBRACE SymTouch and TOSYMRA
Medication Overuse Headache: Overuse of acute migraine drugs may lead to exacerbation headache (medication overuse head- ache). Detoxification of patients, including withdrawal of the overused drugs, and treatment of withdrawal symptoms may be necessary
Serotonin Syndrome: May occur with triptans, including ZEMBRACE SymTouch and TOSYMRA, particularly during co-administration with selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), and monoamine oxidase inhibitors (MAOIs). The onset of symptoms usually occurs within minutes to hours of receiving a new or greater dose of a serotonergic medication. Discontinue ZEMBRACE SymTouch and TOSYMRA if serotonin syndrome is suspected
Increases in Blood Pressure: Significant elevation in blood pressure, including hypertensive crisis with acute impairment of organ systems, has been reported in patients treated with 5-HT1 agonists. Monitor blood pressure in patients treated with ZEMBRACE SymTouch and TOSYMRA
Hypersensitivity Reactions: Hypersensitivity reactions, including angioedema and anaphylaxis, have occurred in patients receiving sumatriptan. Such reactions can be life threatening or fatal. ZEMBRACE SymTouch and TOSYMRA are contraindicated in patients with a history of hypersensitivity reaction to sumatriptan
Seizures: Seizures have been reported following administration of sumatriptan, with or without predisposing factors. ZEMBRACE SymTouch and TOSYMRA should be used with caution in patients with a history of epilepsy or conditions associated with a lowered seizure threshold
Local Irritation (TOSYMRA only): Local irritative symptoms were reported in approximately 46% of patients with TOSYMRA in an open-label trial which allowed repeated use of TOSYMRA over the course of 6 months. The most common of which were application site reaction (eg., burning sensations in the nose), dysgeusia, and throat irritation. Approximately 0.5% of the cases were reported as severe.
ADVERSE REACTIONS
The most common adverse reactions (≥5% and > placebo) were injection site reactions (ZEMBRACE SymTouch only), tingling, dizziness/vertigo, warm/hot sensation, burning sensation, feeling of heaviness, pressure sensation, flushing, feeling of tightness, and numbness/paresthesia.

The World Health Organization (WHO) released its preferred target product profile (TPP) criteria for mpox vaccines at its Mpox Research and Innovation Scientific Conference held August 29-30
TNX-801, Tonix’s attenuated live-virus vaccine candidate, has characteristics that align closely with WHO’s TPP
On August 14, 2024, the WHO determined that the upsurge of mpox in a growing number of countries in Africa constitutes a public health emergency of international concern1–4: cases of the potentially lethal new Clade I mpox also detected in Sweden, Thailand and Singapore
CHATHAM, N.J., Sept. 16, 2024 (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, announced today that the World Health Organization’s (WHO’s) preferred target product profile (TPP), released at the WHO sponsored Mpox Research and Innovation Scientific Conference held August 29-30, 2024, aligns with the characteristics of TNX-801 (horsepox, live virus) vaccine, which is being developed for preventing mpox (formerly known as monkeypox). 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.
“The characteristics of TNX-801 align with the draft TPP released at the WHO sponsored Mpox Research and Innovation Scientific Conference,” said Seth Lederman, M.D., Chief Executive Officer of Tonix. “In animal studies TNX-801 has shown single dose protection against a lethal challenge of Clade I monkeypox virus administered by intratracheal route.5 In addition, protected animals did not produce any infectious virus suggesting TNX-801 has the potential to block forward transmission as expected with live-virus vaccines. TNX-801 is designed for percutaneous administration using a bifurcated needle, like the products and delivery used in WHO’s accelerated smallpox eradication project. Since TNX-801 is a live-virus vaccine, we expect the stability of lyophilized TNX-801 at ambient temperature to be similar to live vaccinia virus vaccines including ACAM2000. We believe TNX-801 can be shipped and stored without the need for a costly and cumbersome ultra-cold supply chain, a particular advantage in lesser developed parts of the world. The stability of live virus vaccines eliminates the need for ultra-cold storage which complicates the widespread use of mRNA vaccines in Africa, where they are needed most right now. Finally, studies on immunocompromised animals6 suggest that TNX-801 may be given to persons with immunocompromising conditions such as HIV, which is another property that will be essential for public health.”
Dr. Lederman continued, “The recent WHO declaration of a Public Health Emergency of International Concern (PHEIC) underscores the urgent need for new vaccines to control this outbreak and save lives. We have been motivated to develop TNX-801 because single-dose vaccines simplify logistics of administration, achieve higher coverage by reducing vaccinee dropout between doses and allow for case-contact or “ring” strategies to vaccinate the contacts of confirmed mpox patients.7,8 Ring vaccination is deemed essential for controlling mpox but requires single-dose vaccines that interrupt forward transmission.”7,8
On August 26, 2024, Tonix announced a collaboration with Bilthoven Biologics (Bbio) to develop GMP manufacturing processes for its mpox vaccine. Bbio is part of the world’s largest vaccine manufacturer, the Cyrus Poonawalla Group, which also includes the Serum Institute of India.
The U.S. Food and Drug Administration (FDA) approved vaccines for mpox are a two-dose non-replicating vaccine called Jynneos® from Bavarian Nordic9 and a one-dose live-virus vaccine from Emergent for people at high risk for mpox infection.10 WHO recently authorized Jynneos for use in adults.11 Recently data in animals have been reported for a two-dose mRNA vaccine from Moderna.12
About TNX-801*
TNX-801 is a live replicating attenuated vaccine based on horsepox that is believed to provide immune protection with better tolerability than 20th Century vaccinia viruses. As previously disclosed, TNX-801 protected animals against lethal challenge with intratracheal Clade I monkeypox virus.5 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.6 The Findings are consistent with mucosal immunity and suggest the ability to block forward transmission, similar to Dr. Edward Jenner’s vaccinia vaccine, which eradicated smallpox and kept mpox out of the human population. TNX-801 combines immune protection with improved tolerability compared to other vaccines based on orthopoxviruses and is administered with a single dose which has advantages over two-dose regimens. The focus on single-dose vaccines confirms early recommendations by the Bipartisan Commission on Biodefense, 7 and the U.S. National Academies of Science.7,8 The National Academies of Science (NAS) report highlights the difficulty of a ring vaccination strategy with even a two-dose regimen. 7 The U.S. National Institutes of Health (NIH) selected Tonix’s COVID-19 vaccine, TNX-1800 for Project NextGen. TNX-1800 is an engineered version of horsepox that expresses the spike protein of SARS-CoV-2. 13,14
About Mpox* On August 14, 2024, the WHO determined that the upsurge of mpox in a growing number of countries in Africa constitutes a PHEIC the second such declaration in the past two years called in response to an mpox outbreak.1 The current outbreak is caused by Clade I monkeypox virus, while the 2022 outbreak was Clade 2 monkeypox virus. The global mpox outbreak, which commenced in 2022 has affected over 90,000 persons in countries where mpox had previously not been endemic, including Europe and the US. The spread of Clade IIb strain mpox in 2022 underscores the pandemic potential of mpox. Unlike Clade IIb mpox, the Clade I strain of mpox appears to be spreading to countries neighboring the Democratic Republic of the Congo, including Burundi, Rwanda, Uganda and Kenya. Clade I mpox is typically associated with approximately twenty times the case fatality rates than Clade IIb mpox in Africa. According to the U.S. Centers for Disease Control and Prevention (CDC), and other experts, there is a significant risk that the deadlier Clade I strain may appear in the U.S.2,3

TNX-801 vaccination demonstrated efficacy in protecting animals from lethal challenge with clade I monkeypox and is in development as an mpox vaccine
New data show improved tolerability in immunocompromised animals and no evidence of spreading to blood or tissues even at high doses
Tonix’s synthetic horsepox vaccine platform has been selected by NIH’s Project NextGen for clinical testing
CHATHAM, N.J., Sept. 09, 2024 (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 data presented at a symposium hosted by the Department of Medical Microbiology & Immunology and the Li Ka Shing Institute of Virology to celebrate the career and honor the retirement of Tonix’s collaborator, David Evans, Ph.D., FCAHS, Emeritus Professor, Department of Cell Biology, University of Alberta. A copy of the Company’s presentation is available under the Scientific Presentations tab of the Tonix website at www.tonixpharma.com.
The presentation titled, “Using Synthetic Biology to Battle Mpox”, detailed the Company’s vaccine platform, led by TNX-801 (horsepox, live virus vaccine for percutaneous administration) for preventing mpox (formerly known as monkeypox). 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 with better tolerability than 20th century vaccinia live-virus vaccines in animals.
TNX-801 is structurally closer to 19th century live-virus vaccinia vaccines than 20th century versions. 1-3 Genomic sequencing of archaic smallpox vaccines has shown that vaccines used prior to 1900 would be called ‘horsepox’ today.1-3 While effective against smallpox as single-dose vaccines, 20th century vaccines have diverged from horsepox-like progenitors to have greater virulence and toxicity than TNX-801 in animals. The U.S. Food and Drug Administration (FDA) recently approved ACAM2000® from Emergent Technologies for preventing mpox.4 ACAM200 is a live-virus vaccine derived from a 20th Century vaccinia vaccine. ACAM2000 carries a Black Box warning on its package insert labeling warning of tolerability issues, including myocarditis and pericarditis, encephalitis, encephalomyelitis, encephalopathy, progressive vaccinia, generalized vaccinia, severe vaccinial skin infections, erythema multiforme major, eczema vaccinatum resulting in permanent sequelae or death, and risks in certain individuals that may result in severe disability, permanent neurological sequelae and/or death.5
The Jynneos® vaccine from Bavarian Nordic is a non-replicating vaccinia vaccine that is FDA-approved for mpox with a two-dose regimen requiring sterile injection.6 Single-dose TNX-801 has advantages over non-replicating vaccinia vaccines which require two doses. Percutaneous TNX-801 has advantages over vaccines which require sterile injection.
The durability of protection from 19th century live-virus vaccinia vaccines was believed to last decades or even be live-long. Consequently, single-dose TNX-801 is believed to stimulate long-lived T cell immunity. Consequently, TNX-801 will not require multiple repeated doses at six-month intervals like mRNA vaccines.7 Also, the stability of live-virus vaccines, particularly in lyophilized form, eliminates the need for ultra-cold storage which complicates the widespread use of mRNA vaccines in Africa, where they are needed most right now.
Tonix’s focus on single-dose vaccines adheres to recommendations by the Bipartisan Commission on Biodefense8, and the U.S. National Academies of Science (NAS).9 For example, the NAS report highlights the difficulty of a case-contact or “ring” vaccination strategy with even a two-dose regimen.9
In the presentation, Tonix highlighted positive preclinical efficacy data, demonstrating that TNX-801 protected animals against lethal challenge with intratracheal clade I monkeypox virus.10 An outbreak of Clade I mpox has recently been declared a Public Health Emergency of International Concern (PHEIC) by the World Health Organization (WHO).11,12 Starting from an outbreak in the Democratic Republic of the Congo, clade I mpox has spread to several Central African Countries and cases have been reported in Sweden, Thailand and Singapore. According to the U.S. Centers for Disease Control and Prevention (CDC), and other experts, there is a significant risk that clade I strain may appear in the U.S.13 Clade I mpox is typically associated with higher case fatality rates than clade II mpox.
After a single dose vaccination, TNX-801 prevented clinical disease and lesions and also decreased shedding in the mouth and lungs of animals challenged with clade I monkeypox.10 These findings are consistent with TNX-801 inducing mucosal immunity and suggest TNX-801 has the ability to block forward transmission, similar to Dr. Edward Jenner’s vaccinia vaccine, descendants of which eradicated smallpox and kept mpox out of the human population.
The presentation at University of Alberta included results from Tonix scientists at the Research and Development Center (RDC) in Frederick, Md. Data from a manuscript showed that TNX-801 is highly attenuated relative to 20th century vaccinia vaccines in in immunocompromised animals.14 New data showed TNX-801 is unable to spread in blood or tissues in these animals, even at an approximately 100-Fold higher dose than 20th century vaccinia vaccines.
In addition to characterizing TNX-801’s activity and tolerability, Tonix scientists have explored the characteristics of the monkeypox virus. The prior 2022 global clade IIb mpox outbreak, affected over 90,000 persons in countries where mpox previously had not been endemic, including Europe and the US. The spread of clade IIb strain mpox in 2022 underscores the pandemic potential of mpox. Data presented show that monkeypox clade IIb from a 2022 isolate in Massachusetts is 10,000- to 100,000-fold more attenuated than clade IIa isolates from 2003. The attenuation of clade II monkeypox in the recent 2022 outbreak may have contributed to its greater dissemination. The new and more lethal clade I monkeypox has not yet been analyzed.
“We are excited to develop TNX-801 to prevent mpox and control mpox epidemics,” said Seth Lederman, M.D., Chief Executive Officer of Tonix. “TNX-801 has conferred protective immunity to animals with single-dose administration. We believe TNX-801 can be manufactured at scale economically with standard shipping and storing requirements. Evidenced by the second WHO declared PHEIC involving an mpox epidemic since 2022, viral diseases are rapidly evolving and our methods to developing effective vaccines must evolve just as rapidly. Synthetic biology is an important technology for vaccine development. We believe the potential of TNX-801 is supported by real world evidence based on the success of horsepox-like vaccines prior to 1900 in protecting against smallpox and containing smallpox outbreaks. When smallpox vaccination with live-virus vaccinia vaccines was employed in Africa prior to eradication, mpox was kept out of the human population.”
Dr. Lederman continued, “We recently announced a collaboration to develop GMP manufacturing processes for TNX-801 with Bilthoven Biologics (Bbio), part of the world’s largest vaccine manufacturer, the Cyrus Poonawalla Group, which also includes the Serum Institute of India. In addition, TNX-801 has the potential to be used as a viral vector platform, for which recombinant versions, like TNX-1800 for COVID-1911,12, can be developed to protect against other infectious diseases that may emerge from this ever-evolving viral landscape. We are excited for TNX-1800’s inclusion into the U.S. National Institute of Health’s (NIH’s) Project NextGen.”
About TNX-801* TNX-801 is a live replicating attenuated vaccine based on horsepox that is believed to provide immune protection with better tolerability than 20th century vaccinia viruses. As previously disclosed, TNX-801 protected animals against lethal challenge with intratracheal clade I monkeypox virus.10 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.10 The Findings are consistent with mucosal immunity and suggest the ability to block forward transmission, similar to Dr. Edward Jenner’s vaccinia vaccine, which eradicated smallpox and kept mpox out of the human population. On August 26, 2024, Tonix announced a collaboration to develop GMP manufacturing processes for its mpox vaccine with Bilthoven Biologics (Bbio), part of the world’s largest vaccine manufacturer, the Cyrus Poonawalla Group, which also includes the Serum Institute of India.
On the horsepox platform, Tonix is developing TNX-1800 (horsepox expressing SARS-CoV-2 spike protein) for protecting against COVID-19. TNX-1800 is an engineered version of horsepox that expresses the spike protein of SARS-CoV-2. In preclinical studies of TNX-1800 highlighted in the presentation, TNX-1800 was tested for immunogenicity and efficacy of TNX-1800 in nonhuman primates following a SARS CoV-2 challenge.14,15 TNX-1800 vaccination results in a neutralizing antibody response that was associated with significant reduction in virus replication/shedding in the respiratory tract and tolerability. 11,12 TNX-1800 was selected by the NIH’s, Project NextGen for inclusion in clinical trials as part of a select group of next generation COVID-19 vaccine candidates with the intent to identify promising vaccine platforms. NIH plans to conduct a Phase 1 trial of TNX-1800 and cover the full cost of the study, while Tonix provides the vaccine candidate.
About Mpox* On August 14, 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, the second such declaration in the past two years called in response to an mpox outbreak. The current outbreak was caused by clade I monkeypox virus, while the 2022 outbreak was clade II monkeypox virus. The global mpox outbreak, which commenced in 2022 has affected over 90,000 persons in countries where mpox had previously not been endemic, including Europe and the US. The spread of clade IIb strain mpox in 2022 underscores the pandemic potential of mpox. Unlike clade IIb mpox, the clade I strain of mpox appears to be spreading to countries neighboring the Democratic Republic of the Congo. Clade I mpox is typically associated with approximately twenty times the case fatality rates than Clade IIb mpox in Africa. According to the U.S. Centers for Disease Control and Prevention (CDC), and other experts, there is a significant risk that the deadlier clade I strain may appear in the U.S.13

(Nasdaq: TNXP) (Tonix or the Company), a fully-integrated biopharmaceutical company with marketed products and a pipeline of development candidates, presented data in an oral presentation at the 2024 Military Health System Research Symposium (MHSRS), held August 26-29, 2024, in Kissimmee, Fla. A copy of the Company’s presentation, titled “Assuaging Agony: Novel Pain Therapeutics”, is available under the Scientific Presentations tab of the Tonix website at www.tonixpharma.com.
In the Phase 3 RESILIENT study, TNX-102 SL met the pre-specified primary endpoint of significantly reducing daily pain compared to placebo (p-value=0.00005) in participants with fibromyalgia. TNX-102 SL demonstrated 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. A post hoc analysis showed strong correlations between improvements in pain and sleep quality at Week 14, supporting the concept that targeting sleep quality has the potential to achieve syndromal improvement in fibromyalgia. TNX-102 SL was well tolerated with an adverse event profile comparable to prior studies and no new safety signals observed.
“Traditional analgesics like NSAIDs or opioids often prove ineffective, if not deleterious, as strategies for treating fibromyalgia,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “In contrast, TNX-102 SL provided broad-spectrum symptom relief in the Phase 3 RESILIENT study and was designed as a bedtime treatment to target non-restorative sleep and improve sleep quality. With the statistically significant results of two positive Phase 3 studies of TNX-102 SL in fibromyalgia we believe TNX-102 SL has the potential to be the first new treatment option for fibromyalgia patients in 15 years.”
Dr. Lederman continued, “Fibromyalgia is the prototypic nociplastic syndrome and chronic overlapping pain condition (COPC)3,4,5. Our results in fibromyalgia suggest potential for TNX-102 SL in treating other COPCs like post-concussive syndrome6, in which sleep disturbances correlate with persistence and severity. In addition, we expect to begin enrolling this quarter in a trial of TNX-102 SL for acute stress disorder/acute stress reaction in the immediate aftermath of motor vehicle collision in the U.S. Department of Defense (DoD)-funded Optimizing Acute Stress Reaction Interventions (OASIS) trial conducted by the University of North Carolina under an investigator-initiated investigational new drug (IND) application.
Tonix remains on track to submit a new drug application (NDA) to the FDA in the second half of 2024 for TNX-102 SL for the management of fibromyalgia. A decision on approval is expected in 2025.

About Fibromyalgia
Fibromyalgia is a chronic pain disorder that is understood to result from amplified sensory and pain signaling within the central nervous system. 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 anxiety and depression, headaches, and abdominal pain or cramps. Individuals suffering from fibromyalgia struggle with their daily activities, have impaired quality of life, and frequently are disabled. Physicians and patients report common dissatisfaction with currently marketed products. According to the recent report from the U.S. National Academies of Sciences, fibromyalgia is a diagnosable condition that may also occur in the context of Long COVID
About TNX-102 SL
TNX-102 SL is a centrally acting, non-opioid, non-addictive, bedtime investigational drug. The tablet is a patented sublingual formulation of cyclobenzaprine hydrochloride developed for the management of fibromyalgia. In December 2023, the company announced highly statistically significant and clinically meaningful topline results in RESILIENT, the second pivotal Phase 3 clinical trial of TNX-102 SL for the management of fibromyalgia. In the study, TNX-102 SL 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 were also seen in all six key secondary endpoints related to improving sleep quality, reducing fatigue and improving overall fibromyalgia symptoms and function. RELIEF, the first statistically significant Phase 3 trial of TNX-102 SL 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. 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). TNX-102 SL was recently granted Fast Track Designation by the FDA for the management of fibromyalgia and remains on track to submit an NDA to FDA in the second half of 2024.
About Nociplastic Pain
Nociplastic pain is the third category of pain distinct from nociceptive pain and neuropathic pain. Nociplastic pain is characterized by pain arising from altered nociception despite no evidence of actual or threatened tissue damage causing activation of peripheral nociceptors or somatosensory system disease or lesion. Its underlying pathophysiology involves altered pain processing by the central nervous system (CNS). Nociplastic syndromes, officially recognized by the International Association for the Study of Pain (IASP) in 2017, also include several other chronic overlapping pain conditions: myalgic encephalomyelitis/chronic fatigue syndrome, irritable bowel syndrome, temporomandibular disorders, forms of chronic back pain and chronic headache. The pathophysiology of nociplastic pain involves central sensitization (CS), where neurons of the CNS become hyperexcitable, amplifying pain signals. CS can be triggered by peripheral pain stimuli, emotional stress, or other factors, leading to persistent pain despite no peripheral nociceptive input.

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 20th 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.

CHATHAM, NJ / ACCESSWIRE / August 23, 2024 / Following an upsurge of cases in the Democratic Republic of the Congo and several other countries in Africa, the World Health Organization (WHO) declared mpox a public health emergency of international concern on Aug. 14 – the second such declaration in two years. The WHO has called on vaccine manufacturers to step up efforts to curb the spread of a new, more deadly strain of the virus.
The WHO also is asking companies and organizations to bring in their vaccines, inviting developers of mpox vaccines to submit an Expression of Interest for Emergency Use Listing (EUL).
Amid this backdrop, Tonix Pharmaceuticals (NASDAQ:TNXP) is developing a vaccine candidate, called TNX-801, that could play a role in combating this escalating global health crisis. Tonix has successfully completed non-human primate studies showing protection from challenge with lethal doses of the Clade 1 monkeypox virus that is driving the new epidemic.
Clearly more testing is ahead for TNX-801, but the technology behind it is rooted in the science of Edward Jenner’s smallpox vaccine of the late 1700s, the only vaccine to successfully eradicate a contagious viral pathogen.
These credentials have earned the vaccine technology platform upon which TNX-801 is based a competitive spot in the NIH’s NextGen program for a more effective, single-dose COVID-19 vaccine to potentially provide durable protection instead of the every-six month booster strategy of mRNA vaccines.
Last month, another of Tonix’s technologies was awarded a contract for up to $34 million by the U.S. Department of Defense to develop a single broad spectrum antiviral that would work against multiple potential biowarfare agents.
An Historical Approach to Modern Challenges The current mpox crisis can be traced back to a decision made in the 1970s to discontinue routine smallpox vaccinations after smallpox was successfully eradicated. Research shows that the smallpox vaccine also provided immunity against mpox. In retrospect, smallpox vaccination kept mpox out of the human population in Africa. So an unintended consequence of stopping vaccinations for smallpox meant that mpox, then known as monkeypox (which is still the name of the virus), was able to reemerge in the human population.
Tonix’s mpox vaccine is believed to be closely related to the original smallpox vaccine invented by British physician Edward Jenner in 1796. Jenner’s vaccine is credited with being the first and only vaccine to successfully eradicate a viral pathogen. This triumph depended on several important attributes of the vaccine, including that it was generally well-tolerated, provided long-term immunity with a single dose, prevented forward transmission and provided a simple biomarker confirmation of protective immunity known as a “take”.
TNX-801 is designed to have these same attributes; it is delivered in a single dose that provides protective immunity to animals that is marked by a “take”. It is believed to have a high likelihood of providing durable immunity and preventing forward transmission. Furthermore, unlike many other vaccines, TNX-801 does not require complex ultra cold-chain storage, making it a strong candidate for global distribution.
The Science Behind TNX-801 Unlike mRNA vaccines, which primarily elicit an antibody response that requires frequent booster shots, TNX-801 is designed to trigger a robust T-cell response. T-cells have the ability to recognize and remember internal parts of viral proteins, not just those on the surface. T-cell memory lasts for years – even decades – providing long-term immunity and potentially eliminating the need for repeated boosters.
In preclinical trials, Tonix says TNX-801 demonstrated the ability to prevent death, clinical disease and lesions caused by a lethal challenge of monkeypox virus in non-human primates. Similar to Jenner’s smallpox vaccine, TNX-801 also significantly reduced viral shedding, suggesting that it can block forward transmission,. Tonix is rushing to manufacture vaccine suitable for Phase 1 human trials.
Beyond Mpox: A Platform for Future Pandemics The vaccine platform on which TNX-801 is based has potential applications beyond mpox. The company says the TNX-1800 version of the platform, for example, is designed to protect against COVID-19 and has shown promise in preclinical studies. The U.S. National Institute of Health has recognized the potential of Tonix’s platform by selecting it for Project NextGen, aimed at developing next-generation COVID-19 vaccines and pandemic platform technologies.
As the world faces the growing threat of mpox and other infectious diseases, Tonix Pharmaceuticals is not only attempting to address the current crisis with TNX-801, but also potentially contributing to a future where pandemics can be more predictably contained.
