Preclinical data demonstrate the efficacy of TNX‐801 vaccination against monkeypox virus challenge in an animal model

Phase 1 trial with TNX-801 for the prevention of monkeypox and smallpox is expected to start in the second half of 2023

CHATHAM, N.J, Feb. 09, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced the publication of a paper entitled, “Single Dose of Recombinant Chimeric Horsepox Virus (TNX‐801) Vaccination Protects Macaques from Lethal Monkeypox Challenge,” in the journal Viruses. The publication demonstrates that a single dose vaccination with TNX‐801 was effective at protecting non-human primates from infection with monkeypox virus. The article can be accessed online at https://www.mdpi.com/1999-4915/15/2/356.

“The global monkeypox outbreak that started in the spring of 2022 reinforced the importance of protecting the population using live virus vaccines,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Consequently, there is a need for an effective and safer, single dose, live replicating vaccine against monkeypox virus. Given the encouraging preclinical data to date, one potential approach is to use a live virus vaccine based on horsepox, such as TNX-801.”

David Evans, Ph.D., FCAHS, Professor and former Vice-Dean (Research) Faculty of Medicine and Dentistry at the University of Alberta and an investigator in the study and author of the publication, said, “It is often forgotten that vaccines don’t always produce sterilizing immunity and so it’s very exciting to be able to report that a horsepox-based vaccine works so well in such a challenging infection model.”

The publication describes data from animals in which eight out of eight vaccinated with TNX-801 were fully protected with sterilizing immunity from a challenge with intra-tracheal monkeypox (central African, or Congo Basin, clade). The vaccinations with TNX-801 were well tolerated as indicated by the lack of any overt clinical disease. These data show that the immunity generated by TNX‐801 was able to provide protection against a lethal challenge with monkeypox virus and is the first study to demonstrate the efficacy of TNX‐801 vaccination against monkeypox virus challenge in a non‐human primate model. Synthetic horsepox virus is the basis for the Company’s TNX-801 vaccine in development to protect against monkeypox and smallpox and for the Company’s Recombinant Pox Virus (RPV) platform to protect against other pathogens, including SARS-CoV-2.

About TNX-801 and TNX-1850

TNX-801 is a live virus vaccine based on horsepox2,3. Tonix is developing TNX-801 for percutaneous administration as a vaccine to protect against monkeypox and smallpox. Tonix is also developing TNX-1850 (horsepox-based live virus vaccine) for the prevention of COVID-19. TNX-1850 is designed to express the spike protein from the BA.2 variant of SARS-CoV-2. Tonix has previously reported positive data from a SARS-CoV-2 challenge study in non-human primates in which animals were vaccinated with TNX-1800, a horsepox-based vaccine expressing spike protein from the Wuhan strain4. Tonix’s TNX-801 is based on the sequence of the 1976 natural isolate Mongolian horsepox clone MNR-763.2 Molecular analysis of DNA sequences suggests that TNX-801 is closer than modern smallpox vaccines to the vaccine discovered and disseminated by Dr. Edward Jenner in 17985-7. For example, recent studies8,9 have shown approximately 99.7% colinear identity between TNX-801 and the circa 1860 U.S. smallpox vaccine VK05.10 The small plaque size in culture of TNX-801 appears identical to the U.S. Centers for Disease Control publication of the natural isolate11. Relative to vaccinia, horsepox has substantially decreased virulence in mice2. Dr. Edward Jenner invented vaccination in 1798 and the procedure was called “vaccination” because ‘cow’ is ‘vacca’ in Latin and the inoculum material was initially obtained from lesions on the udders of cows affected by a mild disease known as cowpox. However, Dr. Jenner suspected that cowpox originated from horses7. Subsequently, Dr. Jenner and others immunized against smallpox using material directly obtained from horses. The use of vaccines from horses was sometimes called ‘equination’ from the Latin ‘equus’ which means ‘horse’12. Equination and vaccination were practiced side-by-side in Europe12,13.

About the Recombinant Pox Virus (RPV) Platform

Horsepox virus and vaccines based on its use as a vector are live replicating viruses that elicit strong immune responses. Live replicating orthopoxviruses, like vaccinia or horsepox, can be engineered to express foreign genes and have been exploited as platforms for vaccine development because they possess; (1) large packaging capacity for exogenous DNA inserts, (2) precise virus-specific control of exogenous gene insert expression, (3) lack of persistence or genomic integration in the host, (4) strong immunogenicity as a vaccine, (5) ability to rapidly generate vector/insert constructs, (6) manufacturable at scale, and (7) ability to provide direct antigen presentation. Horsepox-based vaccines are designed to be single dose, vial-sparing vaccines, that can be manufactured using conventional cell culture systems, with the potential for mass scale production and packaging in multi-dose vials. Tonix’s TNX-801 and RPV vaccine candidates are administered percutaneously using a two-pronged, or “bifurcated” needle. The major cutaneous reaction or “take” to vaccinia vaccine was described by Dr. Edward Jenner in 1796 and has been used since then as a biomarker for protective immunity to smallpox, including in the World Health Organization’s (WHO) accelerated smallpox eradication program that successfully eradicated smallpox in the 1960’s. The “take” is a measure of functional T cell immunity validated by the eradication of smallpox, a respiratory-transmitted disease caused by variola.

About Monkeypox and Smallpox

Monkeypox14 and smallpox15 are diseases in humans caused by the monkeypox and smallpox (or variola) viruses, respectively. Monkeypox and variola are closely related orthopox viruses. Vaccination against smallpox with live virus vaccines based on horsepox or vaccinia protects against monkeypox. After routine smallpox vaccination was stopped in about 1970, monkeypox has become a growing problem in Africa. Since May of 2022, approximately 30,000 cases have been identified in the United States.16,17 There are two distinct clades of the monkeypox virus: the central African (Congo Basin) clade, and the west African clade which is associated with the recent outbreak. Historically, the Congo Basin clade has caused more severe disease than the west African clade. In recent times, the case fatality ratio for the virus is about 3–6%.18 In November, 2022, the WHO began using a new preferred term “mpox” as a synonym for monkeypox.19 Smallpox is considered eradicated, but there are concerns about malicious reintroduction.

Release – Tonix Pharmaceuticals Initiates Enrollment in Phase 2 ‘PREVENTION’ Study of Potentiated Intranasal Oxytocin (TNX-1900) for the Prevention of Migraine Headaches in Chronic Migraineurs

Research News and Market Data on TNXP

February 06, 2023 7:00am EST

Results from Planned Interim Analysis Expected Fourth Quarter 2023

Approximately Four Million in U.S. Suffer from Chronic Migraine

Development of TNX-1900 Also Planned for Treatment of Episodic Migraine

CHATHAM, N.J., Feb. 06, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced that the first participant was enrolled in the Phase 2 ‘PREVENTION’ study of TNX-1900 (intranasal potentiated oxytocin) for the prevention of migraine headache in chronic migraineurs.

The double-blind, placebo-controlled study has a target enrollment of 300 participants at approximately 25 sites across the U.S. Results from a planned interim analysis are expected to be released in the fourth quarter of 2023.

“Despite several classes of migraine preventatives available, there remains an unmet need for novel approaches with an estimated four million individuals in the United States suffering from chronic migraine, often a seriously disabling condition,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “TNX-1900 has a unique, multimodal mechanism of action, that includes an ability to inhibit the release of the trigeminal sensory neuropeptide calcitonin gene-related peptide (CGRP) in blood vessels within the brain, its lining and the brainstem, and to suppress signaling in pain neurons. We believe that by engaging and activating oxytocin receptors in the trigeminal ganglia, TNX-1900 has the potential to help those suffering from chronic migraine. TNX-1900 is a proprietary formulation of oxytocin that contains magnesium, which Tonix has shown in animal models potentiates the action of oxytocin at oxytocin receptors and potentially improves the consistency of treatment by reducing paradoxical high-dose inhibition.”

Shashidar Kori, M.D., former Chief Medical Officer of Trigemina and consultant to Tonix added, “After a decade of development and optimization of our proprietary oxytocin formulation, it is very gratifying and exciting to enter the next stage of testing required to make TNX-1900 available to unfortunate chronic migraine sufferers who have few treatment options. This has the potential to improve the quality of life of people suffering from chronic migraine.”

About the Phase 2 PREVENTION Study

The Phase 2 PREVENTION study is a double-blind, randomized, multicenter, placebo-controlled study to evaluate the efficacy and safety of TNX-1900 taken prophylactically on a daily basis to prevent chronic migraine. There are three arms: two treatment regimens of TNX-1900 and one placebo in a 1:1:1 ratio in a total of 300 participants across approximately 25 U.S. sites. After a four-week Run-In phase to confirm meeting chronic migraine criteria, there are 12-weeks of a double-blind Treatment phase with study drug, followed by a 2-week safety Follow-up phase. The primary efficacy endpoint is mean change in the number of migraine headache days between the 28-day Run-In phase and the last 28-days of the Treatment phase. Key secondary efficacy endpoints include proportion of patients experiencing a ≥ 50% reduction in the number of migraine headache days, mean change in the number of days using migraine abortive medications, and mean change in a migraine-specific quality of life measure. An interim analysis is expected to be completed after the first 50% of enrolled patients have completed the study for the purpose of potential sample size re-estimation, currently anticipated in the fourth quarter of 2023.

About Migraine
Migraine is a neurological condition that typically manifests in a throbbing moderate to severe headache which lasts at least four hours, often on one side of the head and aggravated by routine physical activity. It can also be accompanied by nausea, vomiting, visual disturbances, and sensitivity to bright light and loud noises1. Epidemiological studies indicate that globally, approximately 1.2 billion individuals suffer from migraines annually.2 In the U.S., approximately 39 million Americans suffer from migraines and among these individuals, approximately four million experience chronic migraines (15 or more headache days per month, at least eight of which are migraines).2 The current FDA approved drugs for migraine prevention in chronic migraine include Botox® (onabotulinumtoxin), and the anti-CGRP/CGRP-R monoclonal antibodies Aimovig® (erenumab), Vyepti® (eptinezumab), Ajovy® (fremanezumab) and Emgality® (galcanezumab).

About TNX-1900
TNX-1900 (intranasal potentiated oxytocin) is a proprietary formulation of oxytocin in development as a candidate for prevention of chronic migraine and other conditions. In 2020, TNX-1900 was acquired from Trigemina, Inc. who had licensed the technology underlying the composition and method from Stanford University. TNX-1900 is a drug-device combination product, based on an intranasal actuator device that delivers oxytocin into the nasal cavity. Oxytocin is a naturally occurring human peptide hormone that also acts as a neurotransmitter in the brain. Oxytocin has no recognized addiction potential. It has been observed that low oxytocin levels in the body are associated with increases in migraine headache frequency, and that increased oxytocin levels are associated with fewer migraine headaches. Certain other chronic pain conditions are also associated with decreased oxytocin levels. Migraine attacks are caused, in part, by the activity of pain-sensing trigeminal neurons which, when activated, release of calcitonin gene-related peptide (CGRP) which binds to receptors on other nerve cells and starts a cascade of events that is believed to result in headache. Oxytocin when delivered via the nasal route, concentrates in the trigeminal system3 resulting in binding of oxytocin to receptors on neurons in the trigeminal system, inhibiting the release of CGRP and transmission of pain signals returning from the site of CGRP release.4 Blocking CGRP release is a distinct mechanism compared with CGRP antagonist and anti-CGRP antibody drugs, which block the binding of CGRP to its receptor. With TNX-1900, the addition of magnesium to the oxytocin formulation enhances oxytocin receptor binding5 as well as its inhibitory effects on trigeminal neurons and resultant craniofacial analgesic effects, as demonstrated in animal models7. Intranasal oxytocin has been shown to be well tolerated in several clinical trials in both adults and children6. Targeted nasal delivery results in low systemic exposure and lower risk of non-nervous system, off-target effects, which could potentially occur with systemic CGRP antagonists such as anti-CGRP antibodies8. For example, CGRP has roles in dilating blood vessels in response to ischemia, including in the heart. The Company believes nasally targeted delivery of oxytocin could translate into selective blockade of CGRP release from neurons in the trigeminal ganglion and not throughout the body, which could be a potential safety advantage over systemic CGRP inhibition. In addition, daily dosing is more rapidly reversible, in contrast to monthly or quarterly dosing, as is the case with anti-CGRP antibodies, giving physicians and their patients greater control. In addition to chronic migraine, TNX-1900 will be developed for treatment of episodic migraine, binge eating disorder, craniofacial pain conditions, and insulin resistance. Tonix also has a license with the University of Geneva to use TNX-1900 for the treatment of insulin resistance and related conditions.

About TNX-2900
TNX-2900 is another intranasal potentiated oxytocin-based therapeutic candidate, being developed for the treatment of Prader-Willi syndrome, or PWS. The technology for TNX-2900 was licensed from the French National Institute of Health and Medical Research. PWS, an orphan condition, is a rare genetic disorder of failure to thrive in infancy, associated with uncontrolled appetite later in childhood.

Release – Tonix Pharmaceuticals Announces Acquisition of Preclinical Infectious Disease Portfolio from Healion Bio, Inc.

Research News and Market Data on TNXP

February 02, 2023 7:00am EST

The Acquired Portfolio of Infectious Disease Assets Includes a Class of Potential Broad Spectrum Oral Antiviral Agents, TNX-3900 with a Host-Directed Mechanism

Tonix Plans to Develop the TNX-3900 Series of Molecules as Oral Antivirals Either as Monotherapy or in Combination with Other Antivirals

The TNX-3900 Class of Antivirals Has a Novel Mechanism of Action Based on Inhibition of Certain Cathepsin Proteases which are Required for Cell Infection by Many Viruses like SARS-CoV-2

Sina Bavari, Ph.D., Tonix EVP of Infectious Disease R&D and Director of the Frederick, MD Research and Development Center (RDC) was a Scientific Founder of Healion Bio, Inc.

CHATHAM, N.J., Feb. 02, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced an agreement whereby Tonix has acquired all of the assets of Healion Bio, Inc. (Healion) including its entire portfolio of next-generation antiviral technology assets. Healion’s drug portfolio includes a class of broad-spectrum small molecule oral antiviral drug candidates with a novel host-directed mechanism of action. Host-directed antivirals modulate human cells and tissues and are different from direct-acting antivirals which inhibit virus proteins and processes. Tonix’s TNX-3900, formerly known as HB-121, are cathepsin protease inhibitors, some of which have strong activity in vitro against SARS-CoV-2.

“We are excited to develop Healion’s drug programs that include TNX-3900, which is a class of drugs with potential broad spectrum anti-viral activity, either as monotherapies or in combination with other antivirals”, said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Broad-spectrum antiviral agents have 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. Examples of other classes of host-directed antivirals that have been approved by the U.S. Food and Drug Administration (FDA) include alpha interferon like Pegasys® (peginterferon alfa-2a) for viral hepatitis, the CCR5 antagonist Selzentry® (maraviroc) for HIV, and the anti-IL-6 receptor antagonist monoclonal antibody Actemra® (tocilizumab) for COVID-19.”

Sina Bavari, Ph.D., Executive Vice President for Infectious Disease Research at Tonix said, “I am pleased to be reunited with the infectious disease assets of Healion, since I was the scientific founder of Healion after I retired from my position as Chief of R&D at the United States Army Medical Research Institute of Infectious Disease (USAMRIID). While Healion made some progress developing these advanced technologies, Tonix’s state-of-the art facilities and depth of drug development expertise have the potential to advance the TNX-3900 class of drugs into clinical trials. On behalf of the talented scientific team that I direct at our 48,000 square-foot cutting-edge infectious disease research facility in Frederick, Md., I am pleased to add this technology to the therapeutic development programs underway.”

About TNX-3900

TNX-3900 is the term for a series of molecules that inhibit essential cathepsins which are required by viruses such as coronaviruses and filoviruses to infect cells. Because of the unique antiviral mechanism of these compounds, the Company believes they can potentiate the activity of other antivirals with differing mechanisms. The Company believes this makes cathepsin inhibitors suitable for combination therapy.

Research Study to Assess the Role of TNX-1500 in the Prevention of Heart Xenograft Rejection

Preclinical Xenotransplantation Studies are Expected to Support Regulatory Filings for TNX-1500

CHATHAM, N.J., Feb. 01, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced that it has entered into a sponsored research agreement with the University of Maryland, Baltimore (UMB), for the prevention of rejection in heart xenograft transplantation in animals utilizing TNX-15001, an Fc-modified humanized monoclonal antibody directed against CD40-ligand. UMB’s preclinical studies will utilize genetically-modified porcine hearts supplied by Revivicor, Inc., a subsidiary of United Therapeutics Corporation. The principal investigator is Muhammad M. Mohiuddin, M.D., MBBS, Professor of Surgery, and Director, Cardiac Xenotransplantation Program, University of Maryland School of Medicine.

“We are excited to collaborate with the University of Maryland and Dr. Mohiuddin on the development of TNX-1500 for the prevention of rejection in xenograft transplantation,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “TNX-1500 is a third generation anti-CD40L monoclonal antibody that has been designed by protein engineering to decrease FcγRII binding and to reduce the potential for thrombosis. Previous preclinical studies in non-human primates demonstrated that TNX-1500 showed activity in preventing allograft and xenograft organ rejection and was well tolerated. A positive result from this study would potentially help support an Investigational New Drug (IND) application and human clinical studies.”

“Despite exciting advancements in the field of xenotransplantation, better therapeutics are needed to prevent xenograft organ rejection,” said Dr. Mohiuddin. “Several lines of research indicate that anti-CD40L is required for long term xenograft acceptance. We are excited to collaborate in support of developing an effective immunosuppression regimen for patients requiring xenograft transplantation.”

The primary objective of the preclinical research study is to study the activity of TNX-1500 in preventing cardiac xenograft rejection in animals to support an IND application for human studies.

About TNX-1500

TNX-1500 (Fc-modified anti-CD40L mAb) is a humanized monoclonal antibody that interacts with the CD40-ligand (CD40L), which is also known as CD154. TNX-1500 is being developed for the prevention of allograft and xenograft rejection, for the treatment of autoimmune diseases and for the prevention of graft-versus-host disease (GvHD) after hematopoietic stem cell transplantation (HCT). A Phase 1 study of TNX-1500 is expected to be initiated in the second quarter of 2023. TNX-1500 is a third generation anti-CD40L mAb that has been designed by protein engineering to decrease FcγRII binding and to reduce the potential for thrombosis. In June 2022, Tonix announced data from three oral presentations at the 2022 American Transplant Congress of animal studies found that TNX-1500 showed activity in preventing organ rejection and was well tolerated in non-human primates. In those studies, blockade of CD40L with TNX-1500 monotherapy consistently and safely prevented pathologic alloimmunity in non-human primate models of cardiac and kidney allograft transplantation without clinical thrombosis. Copies of the presentations are available under Scientific Presentations on the Tonix Pharmaceuticals corporate website at www.tonixpharma.com.

Release – Tonix Pharmaceuticals Announces Presentation of Clinical and Non-Clinical TNX-1900 Data at the Annual Headache Cooperative of the Pacific (HCOP) Winter Conference

Research News and Market Data on TNXP

January 31, 2023 7:00am EST

Preliminary Results from Human PET Study Show that Intranasal Application of a Radioisotope of Magnesium-Potentiated Oxytocin is Delivered to the Trigeminal Ganglia

Preliminary Results on Human Cadaveric Trigeminal Ganglia Show Co-expression of Oxytocin Receptors and CGRP

Preliminary Results Show Sex Differences in Oxytocin Potency in an Animal Model

CHATHAM, N.J., Jan. 31, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced that David C. Yeomans, Ph.D., presented data from clinical and nonclinical studies in an oral presentation at the 16th Annual Headache Cooperative of the Pacific (HCOP) Winter Conference on January 27, 2023. The oral presentation titled, “Primary vs Secondary Sex Hormones and Migraine,” includes research sponsored by and licensed to Tonix Pharmaceuticals. Professor Yeomans was a founder of Trigemina, which Tonix acquired, and he remains a consultant to Tonix. A copy of the presentation is available under the Scientific Presentations tab of the Tonix Pharmaceuticals corporate website at www.tonixpharma.com.

“In addition to data showing that magnesium (Mg++) potentiates the analgesic effects of oxytocin, the presentation includes new preliminary data from a Positron Emission Tomography (PET) study in human volunteers dosed with a proprietary nitrogen-13 (13N) radioisotope of oxytocin formulated with Mg++,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “A signal was observed in the trigeminal ganglia, indicating that intranasal oxytocin plus Mg++ delivers oxytocin to the trigeminal ganglia which have known roles in migraine headache. These studies were a collaboration with Aarhus University and the principal investigator, Michael Winterdahl, PhD.”

In addition to the PET study, the presentation includes data collected from isolated human trigeminal ganglia neurons in vitro which show oxytocin receptor co-expressed with calcitonin gene-related peptide (CGRP). The results of these studies, which were performed by postdoctoral fellow Vimala Bharadwaj, PhD, are believed to represent the first observation of oxytocin receptors in human tissue rather than in an animal model. Previously, it has been shown that oxytocin receptors and CGRP co-localize in rat trigeminal ganglia neurons. The cytokine IL-6 functionally upregulated expression of human trigeminal oxytocin receptors in vitro, similar to what has been shown previously in rats, in which oxytocin has been shown to functionally inhibit electrically evoked activity of trigeminal neurons.

Finally, the presentation highlights data which suggest a sex difference in oxytocin potency. “The results indicate that oxytocin is more potent in inhibiting trigeminal ganglion neuronal excitability in female rats compared to males,” said Professor David C. Yeomans. “Moreover, treating male rats with estrogen for four days increased the responsiveness of their isolated trigeminal ganglia to oxytocin in vitro such that they show a similar level of responsiveness to oxytocin as female trigeminal ganglia. The Company believes that together, these findings have potential dosing implications in humans who suffer from chronic migraine.”

In late 2021, Tonix received Investigational New Drug clearance from the U.S. Food and Drug Administration to support the initiation of a Phase 2 study of TNX-1900 (intranasal magnesium potentiated oxytocin) for the prevention of migraine headache in chronic migraineurs. The Company expects to begin enrollment in the Phase 2 study during the first quarter of 2023.

Oral Presentation Describes Activity of Wnt/β-catenin Signaling Pathway Inhibitors Against SARS-CoV-2 in Cell Culture and in an Animal Model

CHATHAM, N.J., Jan. 26, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced that Tom Hobman, Ph.D., Professor of Cell Biology, University of Alberta, presented data from his laboratory at The University of Alberta during a presentation at the 2nd Wnt & β-catenin Targeted Drug Development Conference held in Boston, Mass., on January 26, 2023. The oral presentation titled, “Targeting the Wnt/β -catenin pathway as a broad-spectrum antiviral strategy,” includes research sponsored by Tonix Pharmaceuticals focused on the development and testing of Wnt/β-catenin signaling pathway inhibitors as broad-spectrum antivirals against SARS-CoV-2 and other emerging viruses. Tonix has previously announced that it exercised an option to license the antiviral technology platform. A copy of the presentation is available on the Tonix Pharmaceuticals corporate website at www.tonixpharma.com.

“Antiviral therapeutics are needed to mitigate the effects of SARS-CoV-2 and future coronavirus outbreaks, and Professor Hobman’s work is designed to facilitate the identification and testing of novel broad-spectrum antiviral drugs,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Professor Hobman presented data showing that inhibition of Wnt/β-catenin pathway induces peroxisomes and enhances interferon response during viral infection, significantly reducing SARS-CoV-2 replication in vitro and in vivo.”

“For future pandemics, the scientific community must be ready with an arsenal of easily self-administered drugs that can be tested in rapid, efficient clinical trials immediately after the causative viral agent is identified,” said Professor Tom Hobman. “The research collaboration between Tonix and The University of Alberta is focused on the development and testing of Wnt/β-catenin signaling pathway inhibitors as broad-spectrum antivirals against SARS-CoV-2 and other emerging viruses.”

Release – Tonix Pharmaceuticals Announces Publication of Paper in Antiviral Research Highlighting the Company’s Development of Monoclonal Antibody Therapeutics for Monkeypox and Smallpox

Research News and Market Data on TNXP

January 24, 2023 7:00am EST

Data Represent Research and Development Work Being Conducted at Tonix’s Infectious Disease R&D Center (RDC) in Frederick, Md.

CHATHAM, N.J., Jan. 24, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced the publication of a paper entitled, “Development of a rapid image-based high-content imaging screening assay to evaluate therapeutic antibodies against the monkeypox virus,” in the journal Antiviral Research. The publication describes the development and optimization of two high-content image-based assays that were employed to screen for potential therapeutic antibodies against the monkeypox virus using surrogate poxviruses such as vaccinia virus. The article highlights Tonix’s TNX-3400 platform, which includes antibodies to potentially prevent or treat monkeypox and smallpox. The article can be accessed online at https://pubmed.ncbi.nlm.nih.gov/36592670/.

“These data represent the first wave of research and development conducted at our Infectious Disease R&D Center (RDC) in Frederick, Md,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “The RDC greatly enhances our ability to advance development of our pipeline of vaccines and therapeutics for infectious diseases. The TNX-3400 platform has promise for preventative and therapeutic monoclonal antibodies to treat monkeypox and smallpox.”

“The article describes how we optimized and standardized two high-content high-throughput image-based assays. The first assay was a neutralizing assay which detected viral proteins of vaccinia virus and used the assay to screen a large library of antibodies made against pox viruses. The second assay specifically detected phenotype changes in cells, called syncytia, after infection and protection by therapeutics.” said Sina Bavari, Ph.D., Executive Vice President of Tonix Pharmaceuticals and site director of the RDC. A critical component in assessing antibodies during pandemics requires the development of rapid but detailed methods to detect and quantitate the neutralization activity. “The neutralizing assay identified several antibodies with the capacity to protect against vaccinia virus infection. We believe this technology will allow us to identify combination therapies for monkeypox and smallpox viruses which was difficult to achieve before. Furthermore, our data suggest that applying this technology has the potential to increase the throughput of screening novel antivirals to shorten the discovery time for antivirals.”

About TNX-3400

TNX-3400 is the term for series of monoclonal antibodies which bind to key components of pox viruses such as monkeypox and smallpox and protect cells and tissues from infection with these pandemic causing viruses. These antibodies are being developed as broad-spectrum antipox virus and to potentially prevent or treat monkeypox and smallpox infection.

Results from Planned Interim Analysis of First 50 Percent of Participants Expected Second Quarter 2023

Topline Results Expected Fourth Quarter 2023

Positive Outcome in RESILIENT, Together with Results from Previous Positive Phase 3 RELIEF Study, Would Support Submission of an NDA

CHATHAM, N.J., Dec. 19, 2022 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced that the first 50% of participants have been randomized in the Phase 3 RESILIENT study of TNX-102 SL (cyclobenzaprine HCl sublingual tablets) 5.6 mg for the management of fibromyalgia. An interim analysis by an Independent Data Monitoring Committee (IDMC) of the first 50% of randomized participants for a potential sample size adjustment or early stop for futility is expected in the second quarter of 2023.

TNX-102 SL is in mid-Phase 3 development for the management of fibromyalgia, a chronic pain disorder that afflicts between 6 and 12 million adults in the U.S., of which 90 percent are women. Despite dissatisfaction with currently marketed products, no new treatment for fibromyalgia has been approved by the FDA since 2009.

In December 2020, Tonix reported positive results from the first Phase 3 study (RELIEF) of TNX-102 SL 5.6 mg for the management of fibromyalgia (primary endpoint, p=0.010). Several secondary measures in RELIEF highlighted the broad effects of TNX-102 SL across several cardinal symptoms of fibromyalgia beyond pain. In March 2022, Tonix reported results of a subsequent Phase 3 study (RALLY) in which TNX-102 SL did not achieve statistical significance on the primary endpoint (p=0.115). Relative to the previous positive Phase 3 study (RELIEF), RALLY had an unexpected increase in study participant adverse event-related discontinuations in both the drug and placebo groups. TNX-102 SL was generally well tolerated in both studies with an adverse event profile comparable to prior studies, and no new safety signals observed.

“We are pleased to have reached this important milestone in our ongoing development of TNX-102 SL for fibromyalgia. RESILIENT is a potentially pivotal and confirmatory Phase 3 study, and we look forward to the IDMC’s assessment of interim results in the second quarter of 2023,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Fibromyalgia is a complex syndrome in which many patients remain unsatisfied by existing treatment options. Approximately one-fourth of people with fibromyalgia resort to prescription opioids for analgesia1. TNX-102 SL is a centrally acting analgesic that has the potential to be a new non-addictive, non-opioid bedtime medication for the management of fibromyalgia with broad spectrum symptom coverage.”

About the Phase 3 RESILIENT Study

The RESILIENT study is a double-blind, randomized, placebo-controlled trial designed to evaluate the efficacy and safety of TNX-102 SL (cyclobenzaprine HCl sublingual tablets) in the management of fibromyalgia. The two-arm trial is expected to enroll approximately 470 participants in the U.S. The first two weeks of treatment consist of a run-in period in which participants start on TNX-102 SL 2.8 mg (1 tablet) or placebo. Thereafter, all participants increase their dose to TNX-102 SL 5.6 mg (2 x 2.8 mg tablets) or two placebo tablets for the remaining 12 weeks. The primary endpoint is the daily diary pain severity score change (TNX-102 SL 5.6 mg vs. placebo) from baseline to Week 14 (using the weekly averages of the daily numerical rating scale scores), analyzed by mixed model repeated measures with multiple imputation. An interim analysis by an Independent Data Monitoring Committee will be conducted on the primary endpoint based on the first 50% of enrolled participants for a potential sample size adjustment or early stop for futility.

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 an estimated 6-12 million adults in the U.S., approximately 90% of whom are women. Symptoms of fibromyalgia include chronic widespread pain, nonrestorative sleep, fatigue, and morning stiffness. Other associated symptoms include cognitive dysfunction and mood disturbances, including anxiety and depression. 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.

About TNX-102 SL

TNX-102 SL is a patented sublingual tablet formulation of cyclobenzaprine hydrochloride which provides rapid transmucosal absorption and reduced production of a long half-life active metabolite, norcyclobenzaprine, due to bypass of first-pass hepatic metabolism. As a multifunctional agent with potent binding and antagonist activities at the 5-HT2A-serotonergic, α1-adrenergic, H1-histaminergic, and M1-muscarinic receptors, TNX-102 SL is in development as a daily bedtime treatment for fibromyalgia, PTSD, Long COVID (formally known as post-acute sequelae of COVID-19 [PASC]), alcohol use disorder and agitation in Alzheimer’s disease. The United States Patent and Trademark Office (USPTO) issued United States Patent No. 9636408 in May 2017, Patent No. 9956188 in May 2018, Patent No. 10117936 in November 2018, Patent No. 10,357,465 in July 2019, and Patent No. 10736859 in August 2020. The Protectic™ protective eutectic and Angstro-Technology™ formulation claimed in the patent are important elements of Tonix’s proprietary TNX-102 SL composition. These patents are expected to provide TNX-102 SL, upon NDA approval, with U.S. market exclusivity until 2034/2035.

New Antibodies For COVID-19. Tonix has in-licensed new monoclonal antibodies for treatment or prophylaxis of SARS-CoV-2, the virus that causes COVID-19. The agreement with Curia Global includes three humanized murine monoclonal antibodies that will be developed as second-generation therapy for high-risk patients, including immunocompromised and organ transplant patients.  

Antibodies May Have Broader Efficacy Against Variants. The licensed technology is based on humanized murine antibodies rather than antibodies derived from the blood of COVID-19 patients or (genetically engineered) humanized mice. This may result in a broader immune response that neutralizes more variants and is more difficult for the virus to evade. Only one antibody product with Emergency Use Authorization (EUA) is currently recommended for COVID-19 prophylaxis.
