Topline results expected in the third quarter of 2024; planning a Phase 2 Trial for prevention of kidney transplant rejection

Anti-CD40L has multiple possible indications in addition to solid organ and bone marrow transplantation including autoimmune diseases: potential pipeline in a product

Sanofi recently published results on their Fc-modified humanized anti-CD40L mAb, frexalimab, for multiple sclerosis in the New England Journal of Medicine¹

CHATHAM, N.J., Feb. 28, 2024 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP), a biopharmaceutical company with marketed products and a pipeline of development candidates, today announced the completion of the clinical stage of its Phase 1, single ascending dose escalation trial of TNX-1500 (Fc-modified humanized anti-CD40L monoclonal antibody, or mAb)* in healthy volunteers. TNX-1500 is in development for the prevention of rejection in solid organ and bone marrow transplant and for the treatment of autoimmune disorders.

“Despite advancements in the field of solid organ transplantation, there remains a significant need for new treatments with improved activity and tolerability,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Anti-CD40L modulates T cell function and has the potential to promote tolerance of transplanted organs. We are excited to have completed the clinical stage of this Phase 1 trial of TNX-1500, a third-generation Fc-modified anti-CD40L mAb that has been designed by protein engineering to eliminate the risk of thrombosis associated with first-generation anti-CD40L mAbs. Preclinical studies in non-human primates did not result in any thrombotic complications, suggesting that the protein engineering of TNX-1500’s Fc region has achieved its design goals.”

Dr. Lederman continued, “Recently, positive clinical data with other CD40L blockers have been reported by Sanofi, with its Fc-modified humanized anti-CD40L mAb frexalimab in treating relapsing multiple sclerosis.² Eledon Pharmaceuticals is developing tegoprubart, a non-covalent dimer antibody with no heavy-light or heavy-heavy interchain disulfide bridges for the prevention of rejection of kidney transplants³.”

Dr. Lederman concluded, “We believe TNX-1500 has the potential to prevent organ transplant rejection and improve graft survival with reduced long-term toxicity burden of current immunosuppressive regimens. In addition, TNX-1500 has the potential to address multiple other indications, including several autoimmune diseases. We look forward to the results of this Phase 1 trial, which are expected in the third quarter of this year, and to continuing the development of TNX-1500 as a promising candidate in an important therapeutic space.”

About TNX-1500

TNX-1500 (Fc-modified humanized anti-CD40L mAb) is a humanized monoclonal antibody that interacts with 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. The first-in-human Phase 1 trial of TNX-1500 was initiated in the third quarter of 2023. The primary objective of the Phase 1 trial is to assess the safety, tolerability, pharmacokinetics, 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. This first-in-human 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.^4,5

Tonix plans to File a Clinical Trial Notification (CTN) in Japan and Investigational New Drug (IND) application in China to support a registration-enabling Asian Phase 3 study without dosage adjustment based on U.S. registrational Phase 3 data

Tonmya’s market exclusivity is supported by issued patents in Japan, China, Hong Kong and Taiwan; cyclobenzaprine is a new chemical entity in Japan and China

New Drug Application (NDA) submission to the U.S. FDA for the approval of Tonmya for the management of fibromyalgia planned for second half of 2024

CHATHAM, N.J., Feb. 27, 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, announced positive results from its clinical pharmacokinetic (PK) bridging study of Tonmya™ (also known as TNX-102 SL, cyclobenzaprine HCl sublingual tablets) in healthy adult male and female ethnic Japanese and Chinese volunteers. Results indicate that key pharmacokinetic 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 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.

This study characterized the PK profile and dose proportionality of Tonmya following administration in 20 healthy volunteers of documented Japanese or Chinese ancestry, and compared these findings to an existing PK dataset conducted under similar conditions in Caucasian volunteers.

“This bridging study is an important first step as we begin evaluating the potential for approval and marketing Tonmya in Japan and China. The results show a similar pharmacokinetic profile in ethnic Japanese and Chinese volunteers with a Caucasian comparator group,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “As a result, we believe that these data, with supporting results recently reported from the positive Phase 3 RESILIENT study, are the only clinical data needed to support regulatory filings in Japan and China.”

Dr. Lederman continued, “With patents issued in Japan, China, Hong Kong and Taiwan expected to provide market exclusivity into 2034, we believe that Tonmya would be a welcome addition to the therapeutic options for fibromyalgia patients in East Asia and an attractive asset for the right development and commercialization partners in these markets. Cyclobenzaprine is an NCE in both of these countries. We plan to meet with Japan’s Pharmaceuticals and Medical Devices Agency (PMDA) and China’s National Medical Products Administration (NMPA) to seek agreement on the development of Tonmya in Japan and China, respectively.”

About the Asia Bridging Study

The study was a randomized, single-dose, open-label, 2-way, crossover study design in ethnic Japanese (N=10) and Chinese (N=10) healthy male and female volunteers. The primary objective of the study was to characterize the PK profile and dose proportionality of Tonmya following administration of 2.8 mg and 5.6 mg (one and two 2.8 mg tablets) under fasting conditions in Japanese and Chinese volunteers, and to retrospectively compare these PK data with existing PK data of both cyclobenzaprine and norcyclobenzaprine from a prior Phase 1 study in Caucasian volunteers dosed under the same conditions. Safety and tolerability were also assessed. A 2.8 mg or 5.6 mg dose (2 X 2.8 mg tablet) of Tonmya was administered sublingually in the morning under fasted conditions. Blood samples were collected pre-dose and up to 15 days post-dose for analyte measurements, with a 28-day washout between periods. The primary PK endpoints were the total amount of cyclobenzaprine and metabolite norcyclobenzaprine in the blood (expressed as the area under the curve (AUC_0-T)) and maximum concentration (expressed as C_max).

Study Results

Pharmacokinetics
Ethnic Japanese and Chinese volunteers were considered comparable on PK parameters for cyclobenzaprine following a 2.8 mg and 5.6 mg dose of Tonmya, and dose proportionality was demonstrated in both samples. Given that the similarity in PK profile between Japanese and Chinese volunteers was confirmed, the PK data from the two ethnic groups were pooled for the comparison between Asian (n=20) and Caucasian (n=16) volunteers. The PK parameters of cyclobenzaprine for Japanese, Chinese, and Caucasian groups were similar, with geometric mean ratios falling within the 90% confidence interval.

Safety

• Tonmya was shown to be safe and well-tolerated at doses up to 5.6 mg as single sublingual administrations in healthy adult Japanese and Chinese volunteers.
• The incidence of adverse events (AEs) and investigational product-related AEs was low. No volunteer discontinued due to an AE.
• No clinically significant abnormal findings in laboratory parameters, ECGs, or other safety assessments were noted during the study. No severe AEs and no deaths were reported during the study.

Clinical results show that Tonyma™ has broad-spectrum activity, addressing the three core fibromyalgia symptoms: pain, fatigue, and sleep disturbance

Tonmya™ has a favorable tolerability profile well-suited for chronic treatment

CHATHAM, N.J., Feb. 14, 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, held a key opinion leader (KOL) webinar to discuss the positive Phase 3 data of Tonmya™ (also known as TNX-102 SL, cyclobenzaprine HCl sublingual tablets) for the management of fibromyalgia, and the path to file for FDA approval in the second half of 2024. The webinar was held on January 31, 2024 and hosted by Alliance Global Partners (A.G.P.).

The webinar featured two thought leaders in the field of fibromyalgia: Daniel Clauw, M.D., Professor of Anesthesiology, Medicine and Psychiatry, Director Chronic Pain & Fatigue Research Center, University of Michigan, and Lesley Arnold, M.D., Professor of Psychiatry and Behavioral Neuroscience, University of Cincinnati College of Medicine.

A replay of the webinar is available here.

Tonmya™ is a centrally acting, non-opioid, non-addictive, bedtime medication. As previously announced, Tonix’s second positive Phase 3 study, RESILIENT, met its pre-specified primary endpoint, significantly reducing daily pain compared to placebo (p=0.00005) in participants with fibromyalgia. Statistically significant and clinically meaningful results (p=0.001 or better) were also seen in all key secondary endpoints related to improving sleep quality, reducing fatigue, and improving overall fibromyalgia symptoms and function.

Tonix plans to submit a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) in the second half of 2024 for Tonmya™ for the management of fibromyalgia.

“These data offer new hope for patients with fibromyalgia,” said Dr. Arnold. “Many of my patients have required combination treatments to combat their multiple fibromyalgia-related symptoms. We haven’t seen a medication that can treat fatigue, sleep, and pain all together. Having a compound like Tonmya™ that may address all three is very exciting.”

“The fact that cyclobenzaprine was beneficial in many other key symptom domains, including sleep quality, is important to fibromyalgia patients,” said Dr. Clauw. “We’re really beginning to understand how crucial sleep is in alleviating and potentially preventing fibromyalgia symptoms.”

Dr. Arnold stated that most patients are open to new treatment options, citing lack of efficacy in some cases, tolerability issues and unwanted side effects associated with the currently approved fibromyalgia treatments. “Since patients typically need to be treated for prolonged periods of time, it is important to develop a therapeutic which is well-tolerated.”

“We believe that these positive results show that fibromyalgia can be successfully treated by Tonmya™ and may provide the opportunity for Tonix to have the first FDA-approved drug for fibromyalgia in more than a decade,” said Seth Lederman, M.D., President and Chief Executive Officer of Tonix Pharmaceuticals. “We are now an important step closer to bringing a new, first-line treatment to fibromyalgia patients that offers broad symptom relief and favorable tolerability for chronic use and adherence.”

About the Phase 3 RESILIENT Study
The RESILIENT study was a double-blind, randomized, placebo-controlled trial designed to evaluate the efficacy and safety of Tonmya™ (TNX-102 SL: cyclobenzaprine HCl sublingual tablets) for the management of fibromyalgia. The two-arm trial randomized 457 participants in the U.S. across 33 sites. The first two weeks of treatment consisted of a run-in period in which participants started on TNX-102 SL 2.8 mg (1 tablet) or placebo. Thereafter, all participants increased 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 study met the pre-specified primary endpoint of 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 (p=0.00005).

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 million to 12 million adults in the U.S., the majority 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 Tonmya™ (also known as TNX-102 SL)
Tonmya is a patented sublingual tablet formulation of cyclobenzaprine hydrochloride which is designed for daily administration at bedtime with a proposed mechanism of improving sleep quality in fibromyalgia. Tonmya 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 cholinergic receptors, Tonmya is in development as a daily bedtime treatment for fibromyalgia. TNX-102 SL is also in development fibromyalgia-type 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 Tonmya composition. These patents are expected to provide Tonmya, upon NDA approval, with U.S. market exclusivity until 2034/2035. In addition, Tonix has pending but not issued U.S. patent applications directed to the transmucosal absorption of CBP-HCl, with U.S. market exclusivity expected until 2033, for treating depressive symptoms in fibromyalgia, with U.S. market exclusivity expected until 2032, and for treating pain in fibromyalgia with U.S. market exclusivity expected until 2041.

Tonmya™ is a potential new first-line therapy, non-opioid analgesic for the management of fibromyalgia, supported by statistically significant results from two Phase 3 trials

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

Fibromyalgia is a chronic pain condition affecting approximately 10 million U.S. adults that typically persists for years or decades

CHATHAM, N.J., Feb. 13, 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 that it has engaged Rho, Inc. (Rho), a global contract research organization (CRO), to support Tonix’s preparation and planned submission of its New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for the approval of Tonmya™ (cyclobenzaprine HCl sublingual tablets) for the management of fibromyalgia.

“We are excited by our most recent positive Phase 3 study results of Tonmya and look forward to Rho’s support in preparing our NDA,” said Seth Lederman, M.D., President and Chief Executive Officer of Tonix Pharmaceuticals. “We intend to meet with the FDA in the first half of this year and to submit our NDA in the second half of the year. We believe we have completed all development work required for the NDA, including CMC requirements and the completion of two positive Phase 3 studies.”

Tonmya is a patented sublingual tablet formulation of cyclobenzaprine hydrochloride developed for the management of fibromyalgia. In December 2023, the Company announced highly statistically significant and clinically meaningful topline results in RESILIENT, a second positive Phase 3 clinical trial of Tonmya for the management of fibromyalgia. In the study, Tonmya met its pre-specified primary endpoint, significantly reducing daily pain compared to placebo (p=0.00005) in participants with fibromyalgia. Statistically significant and clinically meaningful results were also seen in all key secondary endpoints related to improving sleep quality, reducing fatigue and improving overall fibromyalgia symptoms and function. RELIEF, the first positive Phase 3 trial of Tonmya in fibromyalgia, was completed in December 2020. It met its pre-specified primary endpoint of daily pain reduction compared to placebo (p=0.010) and showed activity in key secondary endpoints.

“We are delighted in our continued support of Tonix and their Tonmya program,” said Tara Gladwell, President and COO at Rho. “We are hopeful that this work may result in a new treatment for the millions of Americans that suffer from this debilitating, chronic disorder.”

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 million to 12 million adults in the U.S., the majority 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 Tonmya™ (also known as TNX-102 SL)

Tonmya is a patented sublingual tablet formulation of cyclobenzaprine hydrochloride which is designed for daily administration at bedtime with a proposed mechanism of improving sleep quality in fibromyalgia. Tonmya 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 cholinergic receptors, Tonmya is in development as a daily bedtime treatment for fibromyalgia. TNX-102 SL is also in development fibromyalgia-type 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 Tonmya composition. These patents are expected to provide Tonmya, upon NDA approval, with U.S. market exclusivity until 2034/2035. In addition, Tonix has pending but not issued U.S. patent applications directed to the transmucosal absorption of CBP-HCl, with U.S. market exclusivity expected until 2033, for treating depressive symptoms in fibromyalgia, with U.S. market exclusivity expected until 2032, and for treating pain in fibromyalgia with U.S. market exclusivity expected until 2041.

Key Product Candidates* — Recent Highlights

Central Nervous System (CNS) Pipeline

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

• The Company announced in August 2023 that it completed enrollment of its potentially confirmatory Phase 3 RESILIENT trial of TNX-102 SL 5.6 mg in FM. 457 participants were randomized in the trial, which, if successful, is expected to serve as the final, well-controlled efficacy trial required for submission of NDA for approval by the FDA. RESILIENT is a registration-quality, double-blind, placebo-controlled study. Topline results from the RESILIENT trial are expected in late December of 2023.

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

• In September 2023, the Company announced that the UNC Institute for Trauma Recovery has been awarded a $3 million grant from the DoD to investigate the potential of Tonix’s TNX-102 SL to reduce the frequency and severity of adverse effects of acute trauma, which include ASR and ASD, and development of PTSD. 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 MVC 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 or placebo.
• Initiation of patient enrollment in the proposed investigator-sponsored OASIS study is anticipated in the beginning of 2024, subject to clearance by the FDA of an investigator-initiated Investigational New Drug (IND) application.

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

• In September 2023, the Company announced 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 0.5 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. The meeting is expected to take place in the first quarter of 2024.

TNX-1900 (intranasal potentiated oxytocin): small peptide for migraine, craniofacial pain, social anxiety disorder (SAD), insulin resistance and related disorders, and adolescent obesity and binge eating disorder

• In October 2023, the Company announced it completed the clinical phase of the PREVENTION study, a Phase 2 proof-of-concept study of TNX-1900 for the prevention of migraine headaches in chronic migraineurs, as the last of 88 enrolled patients completed their final study visit. PREVENTION is a registration-quality, double-blind, placebo-controlled study.
• Topline results from the PREVENTION Phase 2 trial are expected in early December 2023.
• In September 2023, the Company announced that David C. Yeomans, Ph.D. presented data relevant to the proposed mechanism of TNX-1900 in treating chronic migraine in a poster and an oral presentation at the 2023 International Headache Congress (IHC) in Seoul, South Korea. The poster and oral presentation titled, “Human trigeminal ganglia possess oxytocin receptors on CGRP positive neurons: expression increased by inflammation,” include research sponsored by and licensed to Tonix. The presentations show that oxytocin receptors are co-expressed with calcitonin gene-related peptide (CGRP) on human trigeminal ganglia neurons, which is similar to Professor Yeomans’ previous findings in animal trigeminal ganglia. The inflammatory cytokine IL-6 upregulated expression of oxytocin receptors on human trigeminal neurons, consistent with the previously observed impact of inflammation on the potency of oxytocin on its receptor. In animals, oxytocin has been shown to functionally inhibit the excitability of trigeminal neurons, which is consistent with oxytocin inhibiting the release of CGRP at trigeminal nerve terminals.¹
• Tonix announced in July 2023 that the first participant was enrolled in the investigator-initiated Phase 2 STROBE Study of TNX-1900 for the treatment of binge-eating disorder at MGH. Tonix is supporting the STROBE study through a clinical trial agreement with MGH.
• Tonix announced in July 2023 that the first participant was enrolled in a Phase 2 investigator-initiated, proof-of-concept study of TNX-1900 for enhancing social safety learning in SADSAD. Tonix entered into an agreement with the University of Washington to examine the potential role of TNX-1900 in enhancing vicarious extinction learning in SAD, compared to healthy controls.
• Tonix announced in July 2023 that the first participant was enrolled in the Phase 2 POWER study of TNX-1900 for the treatment of pediatric obesity with MGH. MGH is the sponsor of the NIH-funded trial, being conducted under an investigator-initiated IND.

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 the fourth quarter of 2023. In 2022, Tonix was awarded a Cooperative Agreement grant from NIDA, part of the NIH, to support development of TNX-1300.
• TNX-1300 has been granted Breakthrough Therapy designation by the FDA.

Rare Disease Pipeline

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

• In October 2023, Herbert Harris, M.D., Ph.D., Executive Vice President, Translational Medicine of Tonix Pharmaceuticals, provided an overview of Tonix’s TNX-2900 program at the Foundation for Prader-Willi Research (FPWR) Family Conference in Denver, CO. The presentation highlights preclinical data showing the enhancing effects of magnesium (Mg²⁺) on the activation of oxytocin receptors. The Mg²⁺ enhanced formulation of intranasal oxytocin is the basis for TNX-2900, in development to treat hyperphagia, or pathological over-eating, in children and adolescents with PWS. In preclinical studies, Mg²⁺ increases the potency of oxytocin, which is a peptide hormone that reduces appetite and signals fullness, potentially improving receptor binding and resulting in improved therapeutic action.

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.

• In October 2023, the Company announced data from two oral presentations which were delivered recently at the American College of Surgeons (ACS) Clinical Congress 2023, and The International Pancreas and Islet Transplant Association (IPITA), the International Xenotransplantation Association (IXA), and the Cell Transplant and Regenerative Medicine Society (CTRMS) Joint Congress by faculty at the Center for Transplantation Sciences, MGH. 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 xeno 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 Nature² 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 August 2023, Tonix announced the initiation of a 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.
• The first indication for TNX-1500 will be 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 MGH on allogeneic transplants in animals were published.^3,4

NIAID is conducting early phase clinical trials on select next generation COVID-19 vaccine candidates with the intent to identify promising vaccine candidates

TNX-1800, a live virus percutaneous vaccine candidate, is based on Tonix’s recombinant pox virus (RPV) platform

Phase 1 clinical trial of TNX-1800 expected to start in the second half of 2024

NIAID will cover the full cost of the clinical trial; Tonix will supply the vaccine candidate

CHATHAM, N.J., Nov. 02, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP), a biopharmaceutical company with marketed products and a pipeline of development candidates, today announced that the National Institute of Allergy and Infectious Diseases (NIAID), a part of the National Institutes of Health (NIH), will conduct a Phase 1 clinical trial with TNX-1800 (recombinant horsepox virus, live vaccine),¹ Tonix Pharmaceuticals’ vaccine candidate to protect against COVID-19.

Tonix is developing a novel vaccine platform initially targeting COVID-19, smallpox and mpox (monkeypox). The intent is to provide durable protection against severe disease and prevent forward transmission, primarily by eliciting a T-cell immune response. TNX-1800 expresses the spike protein of SARS-CoV-2, was immunogenic, well tolerated² and showed promise in protecting animals from challenge with SARS-CoV-2 delivered directly into the lungs.³ A related horsepox-based vaccine, TNX-801¹, protected animals against challenge with monkeypox virus delivered directly into the lungs.⁴ TNX-801 is also the vector on which TNX-1800 is based and has been shown to be >1,000-fold more attenuated than modern vaccinia virus vaccine (VACV) strains in immunocompromised mice.⁵ The Phase 1 trial of TNX-1800 is expected to start in the second half of 2024. NIAID will study TNX-1800 by percutaneous administration.

“We believe our novel vaccine platform technology has the potential to provide durable protection from respiratory pathogens and slow their spread,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “TNX-1800 will be the first vaccine candidate using our live virus recombinant pox virus (RPV) platform technology to enter clinical trials. We hope to expand the portfolio of RPV-based vaccines to address several other known respiratory threats including smallpox, mpox and tuberculosis. We are committed to supporting NIAID in assembling a variety of vaccine platform options to ensure the availability of effective vaccines in the face of known and emerging threats. We look forward to participating in the Project NextGen initiative.”

“Project NextGen,” is an initiative by the U.S. Department of Health and Human Services (HHS) to advance a pipeline of new, innovative vaccines and therapeutics for COVID-19. NIAID will be conducting clinical trials to evaluate several early-stage vaccine candidates. The Phase 1 study involving TNX-1800 is designed to assess safety and immunogenicity in approximately 60 healthy adult volunteers. Upon completion of the trial, NIAID and Tonix Pharmaceuticals will assess the results and determine the next steps for the development of TNX-1800.

NIAID will cover the full cost of the clinical trial, including operations and related analysis. 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 U.S. Food and Drug Administration (FDA) to support the approval of its COVID-19 vaccine and other vaccines based on the RPV platform.

About Project NextGen

Project NextGen is a $5 billion initiative to develop the next generation of vaccines and therapeutics to combat COVID-19. Based at the HHS and led by the Administration for Strategic Preparedness and Response’s Biomedical Advanced Research and Development Authority and the NIH’s NIAID, Project NextGen will coordinate across the federal government and the private sector to advance the pipeline of new, innovative vaccines and therapeutics into clinical trials and potential review by the U.S. Food and Drug Administration (FDA) for authorization or approval, and commercial availability for the American people. The program will focus on several areas, including mucosal vaccines, vaccines that provide broader protection against variants of concern and a longer duration of protection, pan-coronavirus vaccines, and new and more durable monoclonal antibodies.

About TNX-1800*
TNX-1800 (recombinant horsepox virus) is a live virus vaccine for percutaneous administration that is designed to express the spike protein of the SARS-CoV-2 virus and to elicit a predominant T cell response. The RPV platform is based on a horsepox vector, which is a live replicating, attenuated virus that has been shown to be >1,000-fold more attenuated than modern VACV strains in immunocompromised mice.⁵ Horsepox and the vaccinia vaccine viruses are closely related orthopoxviruses that are believed to share a common ancestor. Molecular analysis shows that horsepox is closer than modern vaccinia vaccines in DNA sequence to the vaccine discovered and disseminated by Dr. Edward Jenner. ^6-9 Live replicating orthopoxviruses, like vaccinia or horsepox, can be engineered to express foreign genes and have been explored 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) readily manufacturable at scale, and (7) ability to provide direct antigen presentation. Relative to vaccinia, horsepox has substantially decreased virulence in mice.^4,6 The current formulation is a frozen liquid, but we believe that future lyophilized versions can be stored and shipped at standard refrigeration. Horsepox-based vaccines are designed to be single dose, vial-sparing vaccines that can be administered without sterile injection, manufactured using conventional cell culture systems with the potential for mass scale production, and packaged in multi-dose vials. Moreover, we believe the low dose of TNX-1800 makes this technology amenable for future implementation in microneedle delivery systems.

About TNX-801*
TNX-801 (recombinant horsepox virus) is a live virus vaccine based on horsepox^4-7 in pre-clinical development to prevent smallpox and mpox. Tonix reported positive preclinical efficacy data, demonstrating that TNX-801 vaccination protected non-human primates against lethal challenge with monkeypox.⁴ 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.¹⁰ 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. More than 30,000 people have contracted mpox in the U.S. so far during the 2022-23 epidemic,¹¹ The recent cluster of mpox in Chicago revealed breakthrough cases of mpox in individuals who had been vaccinated with the currently authorized non-replicating vaccine, which is administered in two doses.¹² In contrast, TNX-801 is delivered percutaneously with only one dose and therefore may achieve higher rates of community protection by eliminating drop-out between doses and limiting forward transmission. Moreover, relying on only one approved mpox vaccine at present is a risk for the global supply chain that has already led to insufficient availability of vaccines to meet global health needs, especially in Africa. TNX-801 has the potential to make a global impact on mpox and the risk of smallpox because of its durable T-cell immune response, the potential to manufacture at scale, and the use of a lower dose than non-replicating vaccines.

Tonix is a biopharmaceutical company focused on commercializing, developing, discovering and licensing therapeutics to treat and prevent human disease and alleviate suffering. Tonix Medicines, our commercial subsidiary, markets Zembrace® SymTouch® (sumatriptan injection) 3 mg and Tosymra® (sumatriptan nasal spray) 10 mg under a transition services agreement with Upsher-Smith Laboratories, LLC from whom the products were acquired on June 30, 2023. Zembrace SymTouch and Tosymra are each indicated for the treatment of acute migraine with or without aura in adults. Tonix’s development portfolio is composed of central nervous system (CNS), rare disease, immunology and infectious disease product candidates. Tonix’s CNS development portfolio includes both small molecules and biologics to treat pain, neurologic, psychiatric and addiction conditions. Tonix’s lead development CNS candidate, TNX-102 SL (cyclobenzaprine HCl sublingual tablet), is in mid-Phase 3 development for the management of fibromyalgia, having completed enrollment of a potentially confirmatory Phase 3 study in the third quarter of 2023, with topline data expected in late December 2023. TNX-102 SL is also being developed to treat fibromyalgia-type Long COVID, a chronic post-acute COVID-19 condition. Enrollment in a Phase 2 proof-of-concept study has been completed, and topline results were reported in the third quarter of 2023. TNX-1900 (intranasal potentiated oxytocin), is in development as a preventive treatment for chronic migraine, and enrollment has been completed in a Phase 2 proof-of-concept study with topline data expected in early December 2023. TNX-1900 is also being studied in binge eating disorder, pediatric obesity and social anxiety disorder by academic collaborators under investigator-initiated INDs. TNX-1300 (cocaine esterase) is a biologic designed to treat cocaine intoxication and has been granted Breakthrough Therapy designation by the FDA. A Phase 2 study of TNX-1300 is expected to be initiated in the fourth quarter of 2023. Tonix’s rare disease development portfolio includes TNX-2900 (intranasal potentiated oxytocin) for the treatment of Prader-Willi syndrome. TNX-2900 has been granted Orphan Drug designation by the FDA. Tonix’s immunology development portfolio includes biologics to address organ transplant rejection, autoimmunity and cancer, including TNX-1500, which is a humanized monoclonal antibody targeting CD40-ligand (CD40L or CD154) being developed for the prevention of allograft rejection and for the treatment of autoimmune diseases. A Phase 1 study of TNX-1500 was initiated in the third quarter of 2023. Tonix’s infectious disease pipeline includes TNX-801, a vaccine in development to prevent smallpox and mpox. TNX-801 also serves as the live virus vaccine platform or recombinant pox vaccine platform for other infectious diseases, including TNX-1800, in development as a vaccine to protect against COVID-19. The infectious disease development portfolio also includes TNX-3900 and TNX-4000, which are classes of broad-spectrum small molecule oral antivirals.
