The World Health Organization (WHO) declared the spread of new Clade Ib Mpox a public health emergency of international concern (PHEIC): Second Mpox-related WHO PHEIC declaration in two years Clade Ib Mpox cases detected in 16 African countries and outside of Africa, in Sweden, Thailand, Singapore, India, Germany and England Single-dose mpox vaccines with durable protection may be required to address global health emergency TNX-801 was shown to be more than 10- to 1,000-fold more attenuated (or less virulent) compared to the older vaccinia smallpox vaccines: Tolerability of TNX‐801 vaccination in immune-compromised animal models supports clinical development CHATHAM, N.J., Nov. 13, 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 the publication of a paper entitled, “Recombinant Chimeric Horsepox Virus (TNX-801) is Attenuated Relative to Vaccinia Virus Strains in Both In Vitro and In Vivo Models,” in the peer-reviewed journal mSphere. The publication presents data demonstrating that TNX‐801 is less virulent than 20th Century vaccinia vaccines in immune-compromised mice. Previously, single-dose vaccination with TNX-801 was shown to protect animals from a lethal challenge with Clade Ia monkeypox. On August 14, 2024, WHO determined that the upsurge of Clade Ib mpox in Africa constituted a public health emergency of international concern (PHEIC), the second such declaration in the past two years in response to an mpox outbreak. The recent ongoing outbreak is caused by Clade Ib monkeypox virus, while the PHEIC declared in 2022, and still ongoing, is caused by Clade IIb monkeypox virus. Mpox cases of the new clade Ib monkeypox virus have been detect in 16 African countries and Sweden, Thailand, Singapore, India, Germany and England. The new Clade Ib mpox is spreading in children in Africa and so far, has been carried by adult travellers from Africa into non-African countries. The global mpox outbreak from Clade IIb, which commenced in 2022, has affected over 90,000 people in countries where mpox had previously not been endemic, including Europe and the U.S. The Clade IIb mpox from the 2022 PHEIC predominantly affects gay men outside of Africa and already is an established endemic in the U.S. “Addressing the new Clade Ib mpox outbreak and the ongoing spread of Clade IIb mpox may require a single dose mpox vaccine that provides durable protection,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “TNX-801 previously has demonstrated the ability to protect animals from lethal challenge with Clade Ia monkeypox virus. The new findings reported in the peer-reviewed journal mSphere show tolerability of TNX-801 in immune-compromised animals which further supports testing in humans. In addition, we expect TNX-801 can be distributed and stored without a costly supply chain.” The publication describes data in which TNX-801 was compared with older vaccinia vaccine strains used in the eradication of smallpox for tolerability in both in vitro and in vivo models. Together, TNX-801 was shown to be more than 10- to 1,000-fold more attenuated (or less virulent) compared to the older vaccinia smallpox vaccines. Combined with the ability of TNX-801 to protect animals against lethal challenge with Clade Ia monkeypox virus, the Company believes that the new tolerability data support the idea that TNX-801 is a candidate vaccine to control the ongoing PHEICs with mpox Clade Ib and mpox Clade IIb. About TNX-801* TNX-801 (recombinant horsepox virus) is a minimally replicating, 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 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.1 The findings are consistent with mucosal immunity and suggest the ability to block forward transmission, similar to Dr. Edward Jenner’s vaccine, which eradicated smallpox and kept mpox out of the human population.1 TNX-801 is based on synthesized horsepox which is believed to be more closely related to Dr. Jenner’s vaccine than 20th Century vaccinia viruses.2 Smallpox vaccines, descended from Jenner’s vaccine, used prior to 1900 would be called horsepox by modern nomenclature.3-5 TNX-801 is delivered percutaneously with only one dose and therefore may achieve higher rates of community protection than two-dose vaccines by eliminating drop-out between doses and limiting forward transmission. 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.3 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. Tonix also announced a collaboration with the Kenya Medical Research Institute (KEMRI) to design, plan and seek regulatory approval for a Phase I clinical study of TNX-801 in Kenya. The Company believes 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. The FDA-approved non-replicating mpox vaccine Jynneos® requires two doses and provides a relatively short duration of protection.7,8 FDA also recently approved ACAM2000, a live, replicating vaccinia vaccine for prevention of mpox.9 ACAM200 is a clone from DryVax®, a 20th Century vaccinia vaccine derived from the NYCBH strain. Pre-clinical results from an mRNA vaccine recently showed some protection from a Clade I monkeypox challenge, but with multiple break-through lesions in vaccinated animals.10 About the Recombinant Pox Vaccine (RPV) Vaccine Platform* 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.11,12 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.

Submitted New Drug Application (NDA) to FDA for TNX-102 SL for fibromyalgia based on two statistically significant Phase 3 studies Granted Fast Track Designation by FDA in July 2024 for TNX-102 SL, a centrally-acting, non-opioid analgesic; Fibromyalgia is a common chronic pain condition that affects mostly women Expect FDA decision in December 2024 on TNX-102 SL NDA acceptance for review and 2025 PDUFA date; If FDA-approved in 2025, TNX-102 SL would be the first new drug for fibromyalgia in more than 15 years Presented new data on potential mpox vaccine, TNX-801, in September and October 2024, demonstrating tolerability in immunocompromised animals; Previously reported studies showed a single-dose provided immune protection against a monkeypox challenge Awarded U.S. Department of Defense (DoD) contract for up to $34 million over five years in July 2024 to develop a broad-spectrum antiviral drug; Received first payment from DTRA CHATHAM, N.J., Nov. 12, 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 financial results for the third quarter ended September 30, 2024, and provided an overview of recent operational highlights. “With our recent NDA submission to the U.S. Food and Drug Administration (FDA), Tonix is excited about the potential of TNX-102 SL to become the first new drug treatment option in more than 15 years for the roughly 10 million adults in the U.S. suffering from fibromyalgia,” said Seth Lederman, M.D., Chief Executive Officer of Tonix. “FDA awarded TNX-102 SL Fast Track designation in the third quarter of 2024, which is intended to expedite FDA review of important new drugs to fill unmet needs for serious conditions. We look forward to next steps with FDA. If the NDA filing is accepted in December, we expect a decision on the marketing approval of TNX-102 SL for fibromyalgia in 2025.” Dr. Lederman continued, “As we continue to advance key pipeline products through a capital efficient strategy, we are excited to have announced collaborations with world-class institutions to advance the development of TNX-801, a potential mpox vaccine whose single-dose administration and other characteristics align closely with The World Health Organization’s preferred target product profile (TPP) criteria for mpox vaccines. The World Health Organization (WHO) previously announced the growing number of mpox cases constitutes a public health emergency of international concern (PHEIC), with clade 1b mpox strains now detected in 16 countries in Africa as well as in Sweden, Thailand, Singapore, India, England and Germany.” 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 PTSD2,3. 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.

Tonix is expected be the sponsor and KEMRI is expected to lead the execution of the proposed clinical trial.In October 2024, the Company announced it entered into an artificial intelligence and machine learning drug discovery collaboration with X-Chem, Inc., a leader in small molecule drug discovery, to accelerate the development of small molecules as orally available host-targeted broad-spectrum medical countermeasures. Tonix’s TNX-4200 antiviral program focuses on the development of oral CD45 phosphatase inhibitors, with broad-spectrum activity against a range of viral families.In September 2024, Tonix announced the appointment of Thomas Englese as its new Executive Vice President, Commercial Operations. Mr. Englese brings significant leadership to Tonix across several functions, including commercial operations, sales and marketing, and launching and managing major brands through all stages of commercialization. In August 2024, the Company announced a collaboration with Bilthoven Biologics (Bbio) to develop GMP manufacturing processes for TNX-801 as a potential mpox vaccine. Bbio is part of the world’s largest vaccine manufacturer, the Cyrus Poonawalla Group, which also includes the Serum Institute of India. In July 2024, Tonix announced it had been awarded a DoD contract with a potential for up to $34 million over five years by DoD’s Defense Threat Reduction Agency (DTRA). The objective of the contract is 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. Tonix’s program will focus on optimization and development of its TNX-4200 program, to develop an orally available CD45 antagonist, with broad-spectrum efficacy against a range of viral families through preclinical evaluation. The program is expected to establish physicochemical properties, pharmacokinetics, and safety attributes to support an IIND submission and to fund a first-in-human Phase 1 clinical study. Marketed Products – Recent Highlights In September 2024, Tonix announced that the United States Patent and Trademark Office (USPTO) issued U.S. Patent No. 12,097,183 to the Company, claiming 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 fortify protection and market exclusivity into 2036.Tonix announced that the USPTO issued U.S. Patent No. 12,090,139 to the Company, claiming a pharmaceutical composition, a method of treating migraine via intranasal administration, and an intranasal delivery system for Tosymra®. This patent is expected to fortify protection and market exclusivity into 2030. Tonix Medicines launched a national educational campaign focusing on the link between migraine, gastroparesis, and the need for non-oral acute migraine therapies. Tonix Medicines is the only manufacturer with both a branded injectable and nasal spray indicated for the acute treatment of migraine with or without aura in adults. Financial - Recent Highlight As of September 30, 2024, Tonix had approximately $28.2 million of cash and cash equivalents, compared to approximately $24.9 million as of December 31, 2023. Additionally, Tonix had inventory totaling approximately $7.9 million as of September 30, 2024. Net cash used in operations was approximately $46.3 million for the nine months ended September 30, 2024, compared to approximately $79.7 million for the same period in 2023. Cash used in investing activities for the nine months ended September 30, 2024 was approximately $117,000 compared to $28.6 million for the same period in 2023. In July 2024, Tonix received net proceeds of approximately $3.5 million in a securities offering with certain institutional and retail investors. Additionally, during the three months ended September 30, 2024, Tonix sold approximately 134.5 million shares of common stock under the 2024 ATM Sales Agreement for net proceeds of approximately $41.8 million. Third Quarter 2024 Financial Results Net product revenue for the third quarter 2024 was approximately $2.8 million. Net product revenue consisted of combined net sales of Zembrace® SymTouch® and Tosymra®, which were acquired from Upsher-Smith Laboratories, LLC on June 30, 2023. Cost of sales for the third quarter 2024 was approximately $1.6 million. During the three months ended September 30, 2024, Tonix received its first payment from DTRA as part of its previously announced award from DTRA for up to $34 million over five years. Research and development expenses for the third quarter 2024 were approximately $9.1 million, compared to $21.0 million for the same period in 2023. This decrease is predominantly due to lower clinical, non-clinical and manufacturing expenses aligned with the Company’s capital efficient strategy. Selling, general and administrative expenses for the third quarter 2024 were approximately $7.7 million, compared to $8.7 million for the same period in 2023. The decrease was primarily due to lower employee-related expenses, transactional services and sales and marketing expenses partially offset by an increase in professional fees. Net loss available to common stockholders was approximately $14.2 million, or $0.23 per share, basic and diluted, for the third quarter 2024, compared to net loss available to common stockholders of $28.0 million, or $38.63 per share, basic and diluted, for the same period in 2023. The basic and diluted weighted average common shares outstanding for the third quarter 2024 was 62,122,283 compared to 724,190 shares for the same period in 2023.
