TNX-1500 displays potential as a monotherapy or combination therapy to prevent rejection in organ transplantation in allograft and xenograft animal models

Research Directed by Faculty of the Center for Transplantation Sciences, Massachusetts General Hospital

Transplantation is also believed to be a model for treating autoimmunity

CHATHAM, N.J., June 06, 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, announces two oral presentations and a poster presentation at the American Transplant Congress 2024, held June 1-5, 2024 at the Pennsylvania Convention Center, Philadelphia, Pa. A copy of the oral and poster presentation is available under the Scientific Presentations tab of the Tonix website at www.tonixpharma.com.

“We remain encouraged by the potential of our TNX-1500, Fc-modified humanized anti-CD40L monoclonal antibody therapy for the prevention of rejection in solid organ transplantation,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Despite advancements in the field of solid organ transplantation, there remains a significant need for new treatments with improved activity and tolerability. Several lines of research indicate that anti-CD40L therapy may improve outcomes for allograft acceptance, and that anti-CD40L therapy may be required for long term xenograft acceptance. We are excited about the broad potential of TNX-1500, on the prevention of allograft and xenograft rejection and also for the treatment of autoimmune diseases like systemic lupus erythematosus and Sjögren’s Syndrome.”

In the oral presentation titled, “Combined Blockade of the CD154 and CD28 Co-Stimulation Pathways Attenuates Pathogenic Alloimmunity and Prolongs Survival in Cynomolgus Cardiac Allografts”, by Kinoshita, K. et al., data demonstrated that the combined use of TNX-1500 and anti-CD28 monoclonal antibody, VEL-101 is associated with durable protection and graft survival and function in a nonhuman primate model.

In the oral presentation titled, “Extended Survival of 9- and 10-Gene-Edited Pig Heart Xenografts with Ischemia Minimization and CD154 Costimulation Blockade-Based Immunosuppression”, Sanatkar, A. et al., data demonstrated that TNX-1500 has promise to prevent rejection of 9-, or 10-gene-edited (GE) pig hearts.^1,2

The poster presentation titled, “Experience with a Novel Delayed Immune Tolerance Protocol in Nonhuman Primates Based on Anti-CD154, Anti-CD2, and Anti-CD28”, by Ileka, I. evaluated whether a modified protocol based on targeting CD28 and CD2 promotes expansion of peripheral regulatory T-cells and is sufficient to promote heart allograft acceptance.

In February 2024, Tonix announced completion of the clinical stage of its Phase 1 single ascending dose study of TNX-1500 in healthy volunteers. The primary objectives of the study are to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of intravenous TNX-1500. This first-in-human study is intended to support dosing in a planned Phase 2 trial in kidney transplant recipients.

About TNX-1500

TNX-1500 (Fc-modified humanized anti-CD40L mAb) is a humanized monoclonal antibody that binds and blocks the CD40-ligand (CD40L), also known as CD154. TNX-1500 is being developed for the prevention of allograft and xenograft rejection, for the prevention of graft-versus-host disease (GvHD) after hematopoietic stem cell transplantation (HCT) and for the treatment of autoimmune diseases. A first-in-human Phase 1 trial of TNX-1500 has completed the clinical phase. The primary objective of the Phase 1 trial is to assess the safety, tolerability, PK, and pharmacodynamics of intravenous (i.v.) TNX-1500. Eligible participants enrolled in the Phase 1 trial were distributed across three dosing cohorts (3 mg/kg, 10 mg/kg, and 30 mg/kg, respectively) and evaluated regularly over a 120-day period after dosing. The Phase 1 trial is intended to support dosing in a planned Phase 2 trial in kidney transplant recipients. Two published articles in the American Journal of Transplantation demonstrate TNX-1500 prevents rejection, prolongs survival and preserves graft function as a single agent or in combination with other drugs in non-human primate renal and heart allografts. ^3,4

Tonmya treatment was associated with improvement in depressive symptoms as measured by the Beck Depression Inventory-II

In addition, post-hoc analyses showed improvement in depression, anxiety, memory and energy items on the Fibromyalgia Impact Questionnaire-Revised

New Drug Application (NDA) submission to the FDA on track for the second half of 2024

CHATHAM, N.J., June 03, 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, presented new data from the Phase 3 RESILIENT trial of Tonmya (TNX-102 SL, cyclobenzaprine HCl sublingual tablets) for the management of fibromyalgia in an oral presentation at the American Society of Clinical Psychopharmacology (ASCP) Annual Meeting on May 29, 2024 in Miami Beach, Fla. A copy of the presentation is available under the Scientific Presentations tab of the Tonix website at www.tonixpharma.com.

In the oral presentation titled, “Effects of Bedtime TNX-102 SL (Sublingual Cyclobenzaprine HCl) on Mood and Anxiety Symptoms in Fibromyalgia: Results of the Phase 3 RESILIENT Trial,” Seth Lederman, MD, Chief Executive Officer, presented new data suggesting activity for improvement in depressive symptoms with Tonmya.

Depression was frequent among patients enrolled in the RESILIENT trial: ~47% reported experiencing depression within the past 6 months upon fibromyalgia diagnosis and ~25% of the intent-to-treat (ITT) population had experienced a lifetime major depressive episode (MDE). The effect of Tonmya on depressive symptoms was studied using the Beck Depression Inventory-II (BDI-II). Patients started with a baseline mean (standard deviation) for placebo of 10.0 (6.72) and Tonmya of 9.6 (6.32). The BDI-II score separated at Week 2 with a nominal p-value of <0.01. By Week 14, the total BDI-II score in the TNX-102 SL group improved over placebo with a nominal p-value of 0.005 and an effect size of 0.27.

Dr. Lederman said, “Although pain is the prototypic symptom in fibromyalgia and the validated FDA endpoint for the approval of a new drug, depression severity is also a prominent factor in the quality of life for fibromyalgia sufferers. In one study, depressive symptoms had a higher correlation with impaired quality of life than any other symptom, including pain frequency and intensity.² The improvement in depression observed in the Phase 3 RESILIENT was particularly striking since the mean entry score of 10 reflects mild depression. Others have struggled to show benefits of traditional antidepressants in mild depression and consequently many antidepressants have been studied in moderate or severely depressed patients and the benefits of such drugs for patients with mild depression have been inferred.”

Dr. Lederman continued, “In addition to the BDI-II score, in post hoc analyses several individual items on the Fibromyalgia Impact Questionnaire-Revised (FIQR) also improved in the Tonmya-treated group, including : depression (p < 0.001), anxiety (p = 0.001), sensitivity (p = 0.020), memory problems (p = 0.001) and energy (p < 0.001), for which these p-values were not corrected for multiplicity. Together these findings indicate that Tonmya has broad-spectrum activity against fibromyalgia symptoms and may improve fibromyalgia at the syndromal level.”

In the RESILIENT trial, as previously reported, Tonmya improved overall daily pain (p=0.00005), the pre-specified primary endpoint, making it the second Phase 3 study of Tonmya in the management of fibromyalgia to reach statistical significance on the pre-specified primary endpoint. Tonmya also demonstrated statistically significant and clinically meaningful results 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.”

In the RESILIENT trial, there were no new safety signals, low rates of systemic adverse events, and a favorable tolerability profile.

Tonix remains on track to submit an NDA to the U.S. Food and Drug Administration (FDA) in the second half of 2024 for Tonmya for the management of fibromyalgia and has scheduled a Type B pre-NDA meeting with FDA for the second quarter of 2024.

On track to submit NDA in the second half of 2024 for Tonmya™ for fibromyalgia; pre-NDA meeting with FDA scheduled for second quarter 2024

Commercial planning continues for U.S. launch of Tonmya, a potential new first-line, centrally-acting, non-opioid analgesic for the management of fibromyalgia

CHATHAM, N.J., May 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 financial results for the first quarter ended March 31, 2024, and provided an overview of recent operational highlights.

“Our near-term priority continues to be the submission of our New Drug Application (NDA) for Tonmya™ (cyclobenzaprine HCl sublingual tablets) for the management of fibromyalgia, while continuing to build out our commercial strategy for the anticipated product launch in the event of FDA approval, which we currently estimate to occur in the second half of 2025,” said Seth Lederman, M.D., Chief Executive Officer of Tonix.

Dr. Lederman added, “The well-known treatment-limiting side effects of the three currently approved drugs have led to widespread patient dissatisfaction, creating what we believe is a significant opportunity for a new therapeutic. Tonmya has a differentiated mechanism of action and is generally free of common side effects associated with the currently approved products, including weight gain, fatigue, insomnia, increased blood pressure, gastrointestinal issues or sexual dysfunction. As such, we believe Tonmya, if approved, could become the treatment of choice for the approximately 10 million people in the U.S. suffering the debilitating effects of fibromyalgia.”

The Company is also advancing other key pipeline programs including those for immunology, obesity, eating disorders, infectious and rare diseases, many through a capital efficient strategy involving partnerships, grants and in-kind contributions.

Recent Highlights – Key Product Candidates*

Central Nervous System (CNS) Pipeline

Tonmya (also known as TNX-102 SL; cyclobenzaprine HCl sublingual tablets): a centrally-acting, non-opioid, small molecule analgesic taken once-daily at bedtime for the management of fibromyalgia (FM).

• In January 2024, Tonix presented additional safety and tolerability data from the pivotal Phase 3 RESILIENT study that showed Tonmya treatment was not associated with increases in systolic or diastolic blood pressure or body weight, nor were there any reported sexual side effects. The Company had previously announced in December 2023 that the Phase 3 RESILIENT study, a registration-quality, double-blind, placebo-controlled study evaluating Tonyma met its pre-specified primary endpoint in the second of two positive Phase 3 clinical trials, significantly reducing daily pain compared to placebo (p-value=0.00005) in participants with fibromyalgia. Statistically significant and clinically meaningful results were also seen in all 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. Tonmya was well tolerated with an adverse event profile comparable to prior studies and no new safety signals observed. In addition, Tonmya therapy showed activity on improving female sexual function relative to placebo with a nominal p-value=0.010 by the Changes in Sexual Functioning Questionnaire short-form, female version.
• Tonix plans to submit an NDA to the FDA in the second half of 2024 for Tonmya for the management of fibromyalgia. In February 2024, Tonix announced the engagement of Rho, Inc. as our contract research organization (CRO) to support NDA submission.
• In February 2024, Tonix announced statistically significant results from its clinical pharmacokinetic (PK) bridging study of Tonmya in healthy adult male and female ethnic Japanese and Chinese volunteers. Results indicate that key PK parameters of cyclobenzaprine are comparable in ethnic Japanese and Chinese volunteers to Caucasian volunteers from a prior PK study. Tonmya was generally well tolerated in the ethnic Japanese and Chinese healthy volunteers. The company expects these data to fulfill the requirement for a bridging study, and enables Tonix to rely on Phase 3 studies RESILIENT and RELIEF results to support regulatory filings for clinical studies in Japan and China where cyclobenzaprine is a new chemical entity (NCE). Tonix holds issued patents for market exclusivity rights of Tonmya in Japan, China, Hong Kong and Taiwan.
• In March 2024, Tonix announced the selection of two contract manufacturing organizations (CMOs), including Almac Pharma Services, as dual supply sources for the potential launch and commercialization of Tonmya in the U.S.
• In March 2024, Tonix selected EVERSANA, a leading provider of commercialization services to the global life sciences industry, to support the launch strategy and commercial planning of Tonmya in the U.S.
• Tonix presented additional efficacy data from RESILIENT at the 6^th International Congress on Controversies in Fibromyalgia in Brussels, Belgium, March 7-8, 2024. The data showed that Tonmya treatment resulted in an improvement in cognitive dysfunction, or ‘brain fog’, measured by the change in the Fibromyalgia Impact Questionnaire-Revised (FIQ-R) memory item. The FIQ-R cognitive item showed nominal improvement in Tonmya-treated patients vs placebo-treated patients with a nominal p-value=0.001 and effect size of 0.31.

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 February 2024, the Company announced the FDA cleared the Investigational New Drug (IND) application for the Phase 2 investigator-initiated OASIS trial to evaluate TNX-102 SL in reducing the severity of ASR and the frequency of ASD and PTSD. The trial is sponsored by the University of North Carolina Institute for Trauma Recovery and supported by a $3 million grant from the U.S. Department of Defense, which was awarded in September 2023. The proposed Phase 2, Optimizing Acute Stress Reaction Interventions with TNX-102 SL (OASIS) study will examine the safety and efficacy of TNX-102 SL to reduce adverse posttraumatic neuropsychiatric sequelae among patients presenting to the emergency department (ED) after a motor vehicle collision. The study will enroll approximately 180 trauma survivors at ED study sites in the U.S. Participants will be randomized in the ED to receive a two-week course of either TNX-102 SL 5.6 mg or placebo.
• Tonix anticipates the Phase 2 OASIS trial will initiate in the second quarter of 2024.

TNX-102 SL for the treatment of Fibromyalgia-Type Long COVID, also known as Post-Acute Sequelae of COVID-19 (PASC)

• In January 2024, the Company announced the online publication of a research paper in the Journal Pain. The article titled, “Chronic Overlapping Pain Conditions Increase the Risk of Long COVID Features, Regardless of Acute COVID Status,” by Bergmans, et al.¹, found that patients with pre-existing chronic overlapping pain conditions (COPCs) had an increased risk of being diagnosed with symptoms of Long COVID¹. Faculty at the University of Michigan directed the research. Commentary on the article titled, “A step towards better understanding chronic overlapping pain conditions” by Fitzcharles, et al,² is in the same issue of the journal. COPCs include fibromyalgia, chronic fatigue syndrome, migraine headache, irritable bowel syndrome, endometriosis and low back pain. These results contribute to a growing body of evidence that common symptoms of Long COVID in many patients are at least partly driven by central nervous system mechanisms.

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

• Tonix expects to initiate a Phase 2 clinical study of TNX-1300 for the treatment of cocaine intoxication in emergency rooms in the second quarter of 2024. In 2022, Tonix was awarded a Cooperative Agreement grant from the National Institutes of Health (NIH)’s National Institute of Drug Abuse (NIDA) to support development of TNX-1300.
• TNX-1300 has been granted Breakthrough Therapy designation by the FDA.

TNX-1900 (intranasal potentiated oxytocin): small peptide in development through investigator-initiated studies for adolescent obesity, binge eating disorder, bone health in autism and social anxiety disorder (SAD).

• TNX-1900 continues to be studied in four ongoing investigator-initiated Phase 2 studies as follows: Massachusetts General Hospital (MGH): (1) Phase 2 study for binge-eating disorder (BED); (2) Phase 2 study for adolescent obesity; (3) Phase 2 study for improving bone health in children with autism spectrum disorder (BOX); and at University of Washington, (4) Phase 2 study for social anxiety disorder (SAD). The BED study and the adolescent obesity study will investigate whether TNX-1900 has effects on eating behaviors in specialized populations.

Rare Disease Pipeline

TNX-2900 (intranasal potentiated oxytocin): small peptide for the treatment of Prader-Willi syndrome (PWS)

• In March 2024, Tonix announced that it received Rare Pediatric Disease designation from the FDA for TNX-2900 for the treatment of PWS. Tonix has an IND to support clinical development of TNX-2900 to treat PWS in children and adolescents. The planned Phase 2 study is a dose-finding study involving approximately 36 PWS patients divided into four groups with approximately nine per group. One group will receive placebo and three groups will receive different dosage regimens of TNX-2900. TNX-2900 for the treatment of PWS was granted Orphan Drug designation by the FDA in 2022. PWS is a genetic disorder that affects several body systems, with cognitive and behavioral symptoms including pathological over-eating beginning in childhood and leading to severe metabolic sequelae.

Immunology Pipeline

TNX-1500 (anti-CD40L Fc-modified humanized monoclonal antibody): third generation anti-CD40L monoclonal antibody for prophylaxis of organ transplant rejection and treatment of autoimmune disorders.

• The first proposed indication for TNX-1500 is prophylaxis of organ rejection in adult patients receiving a kidney transplant; but multiple additional indications are possible, including autoimmune diseases. Two peer reviewed publications described the work with TNX-1500 at the Massachusetts General Hospital (MGH) on allogeneic transplants in animals.^3,4
• Preclinical studies have shown that TNX-1500 maintains the activity of first-generation monoclonal antibodies (mAbs), yet with reduced risk of thrombotic complications.^3-5 Modeling studies from animal pharmacokinetic data³ predict a half-life of greater than three weeks for TNX-1500 in humans, which supports a monthly i.v. dosing regimen. This analysis together with TNX-1500’s activity and tolerability in animals, suggests that the protein engineering of TNX-1500’s Fc region has achieved its design goals.
• In February 2024, Tonix announced the completion of the clinical stage of its Phase 1 single ascending dose study of TNX-1500 in healthy volunteers. The primary objectives of the study are to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of intravenous TNX-1500. This first-in-human study is intended to support dosing in a planned Phase 2 trial in kidney transplant recipients.
• In March of 2024, the MGH announced the first transplant of a genetically modified pig kidney into a living patient in collaboration with eGenesis, which produced the pig donors and used an anti-CD40L mAb from another company.⁵ Some of the pre-clinical work that supported the living human transplant was performed in collaboration with Tonix and used TNX-1500.⁶ The patient was able to return home after the transplant, but died after approximately two months.⁷

Marketed Products – Recent Highlights

• As of April 1, 2024, Tonix completed the transition to becoming a fully integrated pharmaceutical company. Tonix Pharmaceuticals has implemented personnel, systems and contracts required to support a commercial organization and has assumed responsibility for distribution, selling and marketing of Zembrace SymTouch and Tosymra, as well as supply chain, regulatory and quality control of the two products.

Facilities – Recent Highlights

• In the fourth quarter of 2023, Tonix engaged CBRE, an international real estate brokerage firm, to potentially find a strategic partner for, or buyer of, its Advanced Development Center (ADC) to align with the Company’s current business objectives and priorities. At this time, the Company does not have a commitment in place to sell the building.

Recent Highlights – Financial

As of March 31, 2024, Tonix had $7.0 million of cash and cash equivalents, compared to $24.9 million as of December 31, 2023. Net cash used in operations was approximately $17.6 million for first quarter 2024, compared to net cash used in operations of $32.9 million for the same period in 2023.

On April 1, 2024, the Company closed a financing with existing healthcare-focused institutional investors for upfront gross proceeds of approximately $4.4 million through a registered direct offering. 

First Quarter 2024 Financial Results

Net product revenue for the first quarter 2024 was approximately $2.5 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 first quarter 2024 was approximately $1.7 million.

Research and development expenses for the first quarter 2024 were $12.9 million, compared to $26.5 million for the same period in 2023. This decrease is predominantly due to decreased clinical, non-clinical and manufacturing expenses.

General and administrative expenses for the first quarter 2024 were $9.3 million, compared to $7.4 million for the same period in 2023. The increase was primarily due to sales and marketing and the transition services expenses associated with the Company’s recently acquired marketed products offset by a decrease in financial reporting expenses.

Net loss was $(14.9) million, or $(0.18) per share, basic and diluted, for the first quarter 2024, compared to net loss of $(33.0) million, or $(3.21) per share, basic and diluted, for the same period in 2023. The basic and diluted weighted average common shares outstanding for the first quarter 2024 was 80,879,108 compared to 10,268,500 shares for the same period in 2023.

Research News and Market Data on TNXP

April 01, 2024 4:15pm EDT

Positive results from confirmatory Phase 3 RESILIENT study reported in December 2023 position Tonmya™ for fibromyalgia for NDA submission second half of 2024; pre-NDA meeting with FDA scheduled for second quarter 2024

Commercial planning underway, including go-to-market, supply chain and manufacturing strategies, for U.S. launch of Tonmya, a potential new first-line, centrally-acting, non-opioid analgesic for the management of fibromyalgia

CHATHAM, N.J., April 01, 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 fourth quarter and full year ended December 31, 2023, and provided an overview of recent operational highlights.

“Our near-term focus is seeking U.S. marketing approval for Tonmya (cyclobenzaprine HCl sublingual tablets) for the treatment of fibromyalgia from the U.S. Food and Drug Administration (FDA),” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Our pre-NDA meeting with the FDA is scheduled to take place this quarter and we plan to submit our New Drug Application (NDA) for Tonmya™ in the second half of 2024. We believe the positive Phase 3 RESILIENT results reported in December of 2023 together with the positive results from the first Phase 3 RELIEF study should satisfy the requirements for approval and, if so, would provide the opportunity for Tonix to launch the first FDA-approved drug for fibromyalgia in more than a decade. We believe the activity of Tonmya on improving pain, sleep quality, fatigue and brain fog in the RESILIENT study are indicative of the broad-spectrum of activity in fibromyalgia.”

Dr. Lederman added, “While Tonix is focusing its resources on progressing Tonmya toward NDA submission and potential FDA approval, we are seeking partnerships and collaborations on our pipeline programs from government agencies, non-profit organizations and other biotechnology or pharmaceuticals companies. Tonix has already shifted portions of our research and development (R&D) expenses to U.S. government agencies and other institutions through partnerships involving grants and in-kind contributions. These outside collaborations leverage our internal resources, and we believe they provide a capital efficient strategy for progress.”

Selected Product Candidates* — Recent Highlights

Central Nervous System (CNS) Pipeline

Tonmya (also known as TNX-102 SL; cyclobenzaprine HCl sublingual tablets): a centrally-acting, non-opioid, small molecule analgesic taken once-daily at bedtime for the management of fibromyalgia (FM).

• The Company announced in December 2023 that the Phase 3 RESILIENT study, a registration-quality, double-blind, placebo-controlled study evaluating TNX-102 SL met its pre-specified primary endpoint in the second of two positive Phase 3 clinical trials, 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 key secondary endpoints related to improving sleep quality, reducing fatigue, and improving patient global ratings and overall fibromyalgia symptoms and function. Additionally, as it relates to improving daily pain, treatment with TNX-102 SL showed a robust and clinically meaningful analgesic Cohen’s d effect size of 0.38, with rapid onset of action, separating from placebo for every week of the study. TNX-102 SL was well tolerated with an adverse event profile comparable to prior studies and no new safety signals observed. Tonix plans to submit an NDA to the FDA in the second half of 2024 for TNX-102 SL for the management of fibromyalgia.
• In January 2024, Tonix presented additional safety and tolerability data from the Phase 3 RESILIENT study that showed TNX-102 SL treatment was not associated with increases in systolic or diastolic blood pressure or body weight, nor were there any reported sexual side effects.
• In January 2024, Tonix announced that the FDA has conditionally accepted the trade name, Tonmya, for the Company’s drug product candidate TNX-102 SL for the management of fibromyalgia.
• In February 2024, Tonix announced positive results from its clinical pharmacokinetic (PK) bridging study of Tonmya in healthy adult male and female ethnic Japanese and Chinese volunteers. Results indicate that key PK parameters of cyclobenzaprine are comparable in ethnic Japanese and Chinese volunteers to Caucasian volunteers from a prior PK study. Tonmya was generally well tolerated in the ethnic Japanese and Chinese healthy volunteers. The company expects these data to fulfill the requirement for a bridging study, and enables Tonix to rely on Phase 3 studies RESILIENT and RELIEF results to support regulatory filings for clinical studies in Japan and China where cyclobenzaprine is a new chemical entity (NCE). Tonix holds issued patents for market exclusivity rights of Tonmya in Japan, China, Hong Kong and Taiwan.
• In February 2024, Tonix selected Rho, Inc., a global contract research organization, to support Tonix’s preparation and planned submission of its NDA to the FDA for the approval of Tonmya for the management of fibromyalgia.
• In March 2024, Tonix announced the selection of two CMOs, including Almac Pharma Services, as dual supply sources for the potential launch and commercialization of Tonmya in the U.S.
• In March 2024, Tonix selected EVERSANA, a leading provider of commercialization services to the global life sciences industry, to support the launch strategy and commercial planning of Tonmya in the U.S.
• Tonix presented additional efficacy data from RESILIENT at the 6^th International Congress on Controversies in Fibromyalgia in Brussels, Belgium, March 7-8, 2024. The data showed that Tonmya treatment resulted in an improvement in cognitive dysfunction, or ‘brain fog’, measured by the change in the Fibromyalgia Impact Questionnaire-Revised (FIQ-R) memory item. The FIQ-R cognitive item showed nominal improvement in Tonmya-treated patients vs placebo-treated patients with p-value=0.001 and effect size of 0.31.

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 February 2024, the Company announced the FDA cleared the Investigational New Drug (IND) application for the Phase 2 investigator-initiated OASIS trial to evaluate TNX-102 SL in reducing the severity of ASR and the frequency of ASD and PTSD. The trial is sponsored by The UNC Institute for Trauma Recovery and supported by a $3 million grant from the U.S. Department of Defense (DoD), which was awarded in September 2023. The proposed Phase 2, Optimizing Acute Stress Reaction Interventions with TNX-102 SL (OASIS) study will examine the safety and efficacy of TNX-102 SL to reduce adverse posttraumatic neuropsychiatric sequelae among patients presenting to the emergency department (ED) after a motor vehicle collision (MVC). The study will enroll approximately 180 trauma survivors at ED study sites in the U.S. Participants will be randomized in the ED to receive a two-week course of either TNX-102 SL 5.6 mg or placebo.
• Tonix expects the Phase 2 OASIS trial will initiate in the second quarter of 2024.

TNX-102 SL for the treatment of Fibromyalgia-Type Long COVID, also known as Post-Acute Sequelae of COVID-19 (PASC)

• In January 2024, the Company announced the online publication of a research paper in the Journal Pain. The article titled, “Chronic Overlapping Pain Conditions Increase the Risk of Long COVID Features, Regardless of Acute COVID Status,” by Bergmans, et al. ¹, found that patients with pre-existing chronic overlapping pain conditions (COPCs) had an increased risk of being diagnosed with symptoms of Long COVID¹. Faculty at the University of Michigan directed the research. Commentary on the article titled, “A step towards better understanding chronic overlapping pain conditions” by Fitzcharles, et al,² is in the same issue of the journal. COPCs include fibromyalgia, chronic fatigue syndrome, migraine headache, irritable bowel syndrome, endometriosis and low back pain. These results contribute to a growing body of evidence that common symptoms of Long COVID in many patients are at least partly driven by central nervous system mechanisms.
• In September 2023, the Company reported topline results from its Phase 2 PREVAIL proof-of-concept study of TNX-102 SL for fibromyalgia-type Long COVID. TNX-102 SL showed a robust Cohen’s d effect size of 0.50 in improving fatigue relative to placebo; and it showed consistent activity across secondary measures of sleep quality, cognitive function, disability and Patient Global Impression of Change, but did not meet the primary endpoint of multi-site pain reduction at Week 14. TNX-102 SL was generally well tolerated and no new safety signals were observed. The Company intends to request an End-of-Phase 2 meeting with the FDA to discuss a potential Phase 3 program based on a proposed primary outcome measure using the PROMIS Fatigue scale.

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

• Tonix expects to initiate a Phase 2 clinical study of TNX-1300 for the treatment of cocaine intoxication in emergency rooms in the second quarter of 2024. In 2022, Tonix was awarded a Cooperative Agreement grant from the National Institutes of Health (NIH)’s National Institute of Drug Abuse (NIDA) to support development of TNX-1300.
• TNX-1300 has been granted Breakthrough Therapy designation by the FDA.

TNX-1900 (intranasal potentiated oxytocin): small peptide in development through investigator-initiated studies for bone health in autism, social anxiety disorder (SAD), adolescent obesity and binge eating disorder

• In November 2023, Tonix announced that the first participant was enrolled in an investigator-initiated Phase 2 study of TNX-1900 for improving bone health in children with autism spectrum disorder, named the BOX study, at Massachusetts General Hospital (MGH). The aim of this DoD funded study is to investigate the efficacy and safety of TNX-1900 as a novel therapeutic agent to increase bone density and improve bone structure and strength in children with autism spectrum disorder. Tonix is providing active drug and placebo for the BOX study as part of a drug donation agreement with MGH. MGH is the sponsor of the trial, which is being conducted under an investigator-initiated IND application.
• TNX-1900 is also being studied in three other ongoing investigator-initiated Phase 2 studies as follows:
  
  
  • MGH Phase 2 study for binge-eating disorder (BED)
  • University of Washington Phase 2 study for social anxiety disorder (SAD)
  • MGH Phase 2 study for adolescent obesity

Rare Disease Pipeline

TNX-2900 (intranasal potentiated oxytocin): small peptide for the treatment of Prader-Willi syndrome (PWS)

• In December 2023, Tonix announced that the FDA has cleared the IND application to support clinical development of TNX-2900 to treat PWS in children and adolescents. The Phase 2 study approved under the IND is a dose-finding study involving approximately 36 PWS patients divided into four groups with approximately nine per group. One group will receive placebo and three groups will receive different dosage regimens of TNX-2900. TNX-2900 for the treatment of PWS was granted Orphan Drug designation by the FDA in 2022.
• In March 2024, Tonix announced that it received Rare Pediatric Disease designation from the FDA for TNX-2900 for the treatment of PWS.

Immunology Pipeline

TNX-1500 (anti-CD40L Fc-modified humanized monoclonal antibody): third generation anti-CD40L monoclonal antibody for prophylaxis of organ transplant rejection and treatment of autoimmune disorders.

• The first indication for TNX-1500 is prophylaxis of organ rejection in adult patients receiving a kidney transplant; but multiple additional indications are possible, including autoimmune diseases. Two peer reviewed publications described the work at the Massachusetts General Hospital (MGH) on allogeneic transplants in animals were published.^3,4
• Preclinical studies have shown that TNX-1500 maintains the activity of first-generation monoclonal antibodies (mAbs), yet with reduced risk of thrombotic complications.^3-5 Modeling studies from animal pharmacokinetic data³ predict a half-life of approximately three weeks for TNX-1500 in humans, which supports a monthly i.v. dosing regimen. This analysis together with TNX-1500’s activity and tolerability in animals, suggests that the protein engineering of TNX-1500’s Fc region has achieved its design goals.
• In October 2023, the Company announced data from two oral presentations delivered at medical meetings in 2023. The oral presentations titled, “Pilot Evaluation of a Clinical Xeno Heart Transplant Regimen in a Preclinical Model” and “Extended Survival of 9- and 10-Gene Edited Pig Heart Xenografts with Ischemia Minimization and CD154 Costimulation Blockade-Based Immunosuppression” by Dr. Ikechukwu Ileka et al. include data demonstrating the use of TNX-1500 as maintenance therapy after xenogeneic heart transplant in non-human primates. In both studies, genetically engineered (GE) pigs in baboon transplants were treated with cold-perfused ischemia minimization and a novel costimulation-based immunosuppressive regimen that includes TNX-1500.
• In October 2023, Tonix announced that a study published in the Journal Nature⁵ by faculty at the Center for Transplantation Sciences, MGH, in collaboration with biotechnology company, eGenesis, utilized TNX-1500 as part of the immune modulating regimen to prevent organ transplant rejection. The Nature article titled, “Design and testing of a humanized porcine donor for xenotransplantation” includes data that provide additional support for TNX-1500’s activity in preventing pig xenograft organ rejection and for its safety and tolerability in non-human primates.
• In February 2024, Tonix announced the completion of the clinical stage of its Phase 1 single ascending dose study of TNX-1500 in healthy volunteers. The primary objectives of the study are to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of intravenous TNX-1500. Topline results are expected in the third quarter of 2024. This first-in-human study is intended to support dosing in a planned Phase 2 trial in kidney transplant recipients.
• In March of 2024, the MGH announced the first transplant of a genetically modified pig kidney into a living patent in collaboration with eGenesis, which produced the pig donors.⁶ Some of the pre-clinical work that supported this transplant was performed in collaboration with Tonix and used TNX-1500.⁵

Infectious Disease Pipeline

TNX-1800 (modified recombinant horsepox virus, live vaccine): potential vaccine to protect against COVID-19 designed to express the SARS-CoV-2 spike protein

• Results from a study with our TNX-1800 vaccine that showed animals were protected from challenge with SARS-CoV-2 were published as an article in the peer reviewed journal, Viruses in 2023.⁷
• In November 2023, Tonix announced that NIH and National Institute of Allergy and Infectious Diseases (NIAID) will conduct a Phase 1 clinical trial with TNX-1800 as part of Project NextGen. NIAID will cover the full cost of the clinical trial, including operations and related analyses. Tonix will be responsible for providing clinical trial materials, and upon completion will have the right to rely on the findings in regulatory filings with the FDA to support the approval of its COVID-19 vaccine and other vaccines based on the recombinant pox vaccine (RPV) platform.
• We believe the TNX-1800 vaccine development plan addresses several priority vaccine attributes advanced by the White House Office of Science and Technology Policy’s Pandemic Preparedness Plan,⁸ the National Biodefense Science Board⁹ and BARDA.¹⁰ Tonix believes its RPV platform can address a wide variety of disease targets of public health interest. 

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

• Results from a study with our TNX-801 vaccine that showed animals were protected from mpox were reported at a meeting in the first quarter of 2020 and published as an article in the peer reviewed journal, Viruses in 2023.¹¹
• On December 14, 2023, Dr. Lederman participated in a panel discussion on Vaccine Research & Development at the National Academies of Sciences, Engineering, and Medicine (NAS) Committee on the Current State of Research, Development, and Stockpiling of Smallpox Medical Countermeasures public meeting. Discussions explored lessons learned from the recent COVID-19 pandemic and mpox multi-country outbreak to inform an evaluation of the current state of research, development, and stockpiling of smallpox readiness and response measures. The Consensus Study Report was issued on March 28, 2024.¹² Some of the conclusions included recommendations for single dose vaccines, safer vaccines, vaccine platforms and attention to supply chain and manufacturing. Tonix believes TNX-801 has the potential to address some of the recommendations from the NAS Committee since it provides single dose protection to animals, and has the potential for favorable dose, manufacturing and cold chain requirements.
• In August 2023, Tonix received the official written response from a Type B pre-IND meeting with the FDA to develop TNX-801 as a potential vaccine to protect against mpox disease (formerly known as monkeypox) and smallpox. 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. The Phase 1/2 clinical trial will assess the safety, tolerability, and immunogenicity of TNX-801, following the submission and clearance of an IND.
• Concerns about current state of new smallpox and mpox vaccines in development have been raised by the U.S. Bipartisan Commission on Biodefense¹³ and by an outbreak of mpox in the Democratic Republic of the Congo.¹⁴
• Results from a study with our TNX-801 vaccine that showed decreased virulence relative to traditional live vaccinia vaccine strains were posted on the website BioRxiv in 2023.¹⁵

Broad-spectrum anti-viral programs

Tonix is developing potential broad-spectrum antiviral drugs in three programs: CD45-targeted therapeutics (TNX-4200), cathepsin inhibitors (TNX-3900) and viral glycan-targeted engineered biologics (TNX-4000). In 2020, the DoD announced that they are seeking broad spectrum antiviral drugs since it would be hard to predict which or how many viruses may be deployed on the battlefield.¹⁶ Tonix hopes that one or more of our programs may help the DoD address that goal.

Marketed Products — Recent Highlights

• Tonix completed the acquisition of Zembrace^® SymTouch^® (sumatriptan injection) 3 mg and Tosymra (sumatriptan nasal spray) 10 mg from Upsher-Smith Laboratories, LLC on June 30, 2023. Both products are indicated for the treatment of acute migraine with or without aura in adults.
• Combined net product revenue of $7.8 million reported for the period July 1, 2023 – December 31, 2023 for Zembrace Symtouch and Tosymra.
• As of April 1, 2024, Tonix completed the transition to becoming a fully integrated pharmaceutical company. Tonix Pharmaceuticals has implemented personnel, systems and contracts required to support a commercial organization and has assumed responsibility for distribution, selling and marketing of Zembrace SymTouch and Tosymra, as well as supply chain, regulatory and quality control of the two products.

Research News and Market Data on TNXP

March 25, 2024 8:00am EDT

TNX-2900 is a proprietary magnesium-potentiated formulation of intranasal oxytocin, a naturally occurring hormone that reduces appetite and eating

Prader Willi syndrome is the most common genetic cause of life-threatening childhood obesity

CHATHAM, N.J., March 25, 2024 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a biopharmaceutical company with marketed products and a pipeline of development candidates, today announced the U.S. Food and Drug Administration (FDA) has granted Rare Pediatric Disease Designation to TNX-2900* (intranasal potentiated oxytocin), a proprietary magnesium (Mg2⁺)-potentiated formulation of intranasal oxytocin, to treat Prader-Willi syndrome (PWS) in children and adolescents. TNX-2900 was previously granted Orphan Drug designation by the FDA in 2022 for the treatment of PWS and the investigational new drug (IND) application was cleared by the FDA in 2023. The Company may be eligible to receive a transferable Priority Review Voucher if TNX-2900 for PWS is approved for marketing. Recently, vouchers have sold for approximately $100 million.

“The Rare Pediatric Disease Designation is an important regulatory milestone in the development of TNX-2900. With PWS being the most common genetic cause of life-threatening childhood obesity, we are excited that the FDA has recognized this significant unmet need in children and adolescents, particularly for PWS hyperphagia, which currently has no approved treatments^1,2,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “As PWS is a genetic disorder associated with abnormalities of the oxytocin system, Tonix believes TNX-2900’s unique formulation has the potential to improve intranasal oxytocin’s therapeutic action by addressing limitations in efficacy observed at high-dose intranasal oxytocin that is not Mg2⁺-potentiated^3,4.”

The FDA defines a rare pediatric disease as a serious or life-threating disease that primarily affects individuals aged from birth to 18 years and affects under 200,000 people in the United States.

About FDA’s Rare Pediatric Disease Priority Voucher Program

The FDA’s Rare Pediatric Disease Priority Voucher Program is intended to encourage the development of new drugs to treat certain rare pediatric diseases. Under the FDA’s Rare Pediatric Disease Designation and Voucher Program, if TNX-2900 is approved for marketing, Tonix may qualify for a priority review voucher that can be redeemed to receive priority review of a subsequent marketing application for a different product. Priority review vouchers may also be sold or transferred to another sponsor. The new sponsor can redeem the voucher to receive priority review for a different product, which reduces the review time of NDAs from 10 months to six months. There is no limit on the number of times a priority review voucher can be transferred. A 2020 U.S. Government Accounting Office analysis⁵ of the voucher program found that in the ten years since launch of the program in 2009, the price of buying priority review vouchers ranged from $67 million to $350 million. More recently, priority review vouchers were acquired by Novo Nordisk for $110 million in June of 2022, and by Novartis for $100 million from Marinus in July of 2022.⁶   Bluebird Bio sold vouchers for $102 million, $95 million and $103 million in November 2022, January 2023, and October 2023, respectively.^7-9 In June of 2023, Novartis bought a priority review voucher from Pharming for $21 million, a price that had been negotiated as part of a purchase agreement when Pharming acquired the asset from Novartis.⁵

About Prader-Willi Syndrome (PWS)

PWS is recognized as the most common genetic cause of life-threatening childhood obesity and affects males and females with equal frequency and all races and ethnicities. PWS results from the absence of expression of a group of genes on the paternally acquired chromosome 15. The hallmarks of PWS are lack of suckling in newborns and, in children and adolescents, severe hyperphagia – an overriding physiological drive to eat, leading to severe obesity and other complications associated with significant mortality. A systematic review of the morbidity and mortality as a consequence of hyperphagia in PWS found that the average age of death in PWS was 22.1 years.¹⁰ There is no approved medication to treat poor feeding in newborns or hyperphagia in children and adolescents with PWS. Given the serious or life-threatening manifestations of these conditions, there is a critical need for effective treatments to decrease morbidity and mortality, improve quality of life, and increase life expectancy in people with PWS. Oxytocin has potent effects in correcting behavioral characteristics of the Magel2 knock-out mouse model for PWS and autism.^11-13 Six clinical trials have investigated intranasal oxytocin as a treatment in pediatric patients with PWS. Four studies showed evidence for improvement in PWS-related behaviors/symptoms^14-17; three clinical studies reported evidence for improvement in hyperphagia^14,15,17; and one clinical study showed an improvement in sucking in infants¹⁶.

About TNX-2900 and Tonix’s Potentiated Oxytocin Platform

TNX-2900 is based on Tonix’s patented intranasal Mg²⁺-potentiated oxytocin formulation intended for use by children and adolescents. This formulation is believed to enhance the potency of oxytocin as well as increase specificity for oxytocin receptors relative to vasopressin receptors, potentially reducing unwanted side effects from activating vasopressin receptors. Tonix is also developing a different intranasal formulation, designated TNX-1900 for adolescent obesity, binge eating disorder, bone health in autism, and social anxiety disorder. Oxytocin is a naturally occurring human hormone that acts as a neurotransmitter in the brain. Oxytocin is believed to be more than 600 million years old and is present in vertebrates including mammals, birds, reptiles, amphibians, and fish.¹⁸ It was initially approved by the U.S. Food and Drug Administration as Pitocin®**, an intravenous infusion or intramuscular injection drug, for use in pregnant women to induce labor and control postpartum bleeding or hemorrhage. An intranasal formulation of oxytocin is marketed in some European countries to assist in breast milk production as Syntocinon®*** (oxytocin nasal 40 units/ml).
