Four Phase 2 investigator-initiated studies of TNX-1900 (intranasal potentiated oxytocin) are ongoing for pediatric obesity, binge eating disorder, bone health in autism and social anxiety disorder

TNX-2900 (intranasal potentiated oxytocin) is being developed under an IND as a treatment for Prader-Willi Syndrome, an Orphan Disease characterized by excessive eating

TNX-1900 and TNX-2900 may serve as novel neuroendocrine treatments for certain pain, eating and endocrine disorders 

CHATHAM, N.J., March 21, 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 announces a poster presentation at the American Chemistry Society (ACS) Spring 2024 Meeting, held March 17-21, 2024, in New Orleans, Louisiana. A copy of the poster is available under the scientific presentations page of the Tonix website at www.tonixpharma.com.

The poster presentation titled, Oxytocin Analogs with Enhanced Craniofacial Antinociceptive Effects in Low Magnesium Formulations, describes the discovery and characterization of novel oxytocin analogues that are candidate treatments for craniofacial pain, excessive eating (including Prader Willi Syndrome), and endocrinological conditions including bone health in autism and insulin resistance.

“Intranasal oxytocin has several potential therapeutic applications,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Preclinical studies have shown that oxytocin, a hypothalamic peptide hormone, simultaneously reduces food intake and increases energy expenditure, leading to weight loss.^1-3 Intranasal oxytocin is well-tolerated and in published studies of adults, results in reduced caloric intake, increased fat burning and improved insulin sensitivity.^1-3”

Dr. Lederman continued, “There is preclinical evidence that the activity of intranasal oxytocin is dependent on magnesium (Mg⁺⁺) concentration.^4-6 Our current intranasal oxytocin formulations of TNX-1900 and TNX-2900 contain Mg⁺⁺ to augment the activity. We believe the new oxytocin analogues described in the poster have enhanced binding to Mg⁺⁺ and consequently their activity does not require Mg⁺⁺ augmentation.”

Four Phase 2 investigator-initiated studies of TNX-1900 are currently ongoing; three at the Massachusetts General Hospital (MGH) and one at the University of Washington. The Phase 2 ‘POWER’ study at MGH is investigating the efficacy and safety of TNX-1900 as a novel therapeutic agent to induce weight loss and improve indicators of cardiometabolic risk in adolescent patients with obesity. The Phase 2 ‘STROBE’ study at MGH is investigating the efficacy and safety of TNX-1900 as a novel therapeutic agent to reduce binge eating frequency in adults with binge-eating disorder. The Department of Defense (DoD)-funded Phase 2 ‘BOX’ study at MGH is investigating the efficacy and safety of TNX-1900 as a novel therapeutic agent to improve bone health in children with autism spectrum disorder. In addition, a Phase 2 study at the University of Washington is investigating the potential role of TNX-1900 in enhancing vicarious extinction learning in social anxiety disorder, compared to healthy controls.

About TNX-1900 and TNX-2900

TNX-1900 and TNX-2900 (intranasal potentiated oxytocin) are proprietary formulations of oxytocin. TNX-1900 is in Phase 2 development under investigator-initiated INDs as a candidate for adolescent obesity, binge eating disorder, bone health in autism and social anxiety disorder. TNX-1900 is also planned for development in treating insulin resistance. TNX-2900 is in development as a treatment for Prader Willi Syndrome. TNX-2900 has received orphan drug designation from the U.S. Food and Drug Administration (FDA) and its IND has been cleared. 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. Tonix’s patented intranasal potentiated oxytocin formulation intended for use by adults and adolescents. Tonix’s patented potentiated oxytocin formulation is believed to increase specificity for oxytocin receptors relative to vasopressin receptors as well as to enhance the potency of oxytocin. 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.⁷ It was originally 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. An intranasal formulation of oxytocin is marketed in some European countries to assist in the production of breast milk as Syntocinon^®** (oxytocin nasal 40 units/ml). Oxytocin has no recognized addiction potential. Oxytocin, when delivered via the nasal route, concentrates in the trigeminal system¹ resulting in binding of oxytocin to receptors on neurons in the trigeminal system. With TNX-1900 and TNX-2900, the addition of magnesium to the oxytocin formulation enhances oxytocin receptor binding⁸ as well as its inhibitory effects on trigeminal neurons and resultant craniofacial analgesic effects, as demonstrated in animal models⁹. Intranasal oxytocin has been shown to be well tolerated in several clinical trials in both adults and children¹⁰. Targeted nasal delivery results in low systemic exposure and lower risk of non-nervous system, off-target effects. Tonix also has a license with the University of Geneva to use TNX-1900 for the treatment of insulin resistance and related conditions.

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.¹¹ There is no approved medication to treat poor feeding in newborns or hyperphagia in children and adolescents with PWS. Given these 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 adult mice correcting behavioral characteristics of the Magel2 knock-out mouse model for PWS and autism.¹² In addition, oxytocin has potent effects in correcting behavioral characteristics of the neonatal Magel2 knock-out mouse model for PWS and autism¹³ and intriguing effects in a clinical trial of neonates with PWS.¹⁴

Bedtime TNX-102 SL improves sleep quality in PTSD and is also being developed for the management of fibromyalgia for which NDA preparation is ongoing

Investigator-Initiated OASIS Trial at UNC is a Phase 2 180-patient, randomized, placebo-controlled trial in acute trauma patients following motor vehicle collisions

One-third of emergency department visits in the U.S. (40-50 million patients per year) involve evaluation after trauma exposures

CHATHAM, N.J., Feb. 12, 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 cleared the Investigational New Drug (IND) application for the Phase 2 investigator-initiated OASIS trial to evaluate TNX-102 SL¹ in reducing the severity of acute stress reaction (ASR) and the frequency of acute stress disorder (ASD) and posttraumatic stress disorder (PTSD). The trial is sponsored by The University of North Carolina (UNC) Institute for Trauma Recovery and supported by a $3 million grant from the U.S. Department of Defense (DoD).

“No medication is currently available at or near the point-of-care to treat patients suffering from traumatic events and support long-term health,” said Seth Lederman, M.D., Chief Executive Officer of Tonix. “There is an unmet need for treating ASR after traumatic events such as civilian motor vehicle collisions or warfighter experiences in forward bases or in theater. Previous trials of TNX-102 SL in PTSD suggested activity on sleep and stress related symptoms in the first several weeks of treatment.^2,3 The study is motivated by the observation that the symptoms of ASR and PTSD are similar and by the hypothesis that TNX-102 SL’s effect on sleep quality may reduce ASR symptoms.”

The Optimizing Acute Stress Reaction Interventions with TNX-102 SL (OASIS) trial 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 trial will enroll approximately 180 trauma survivors at ED study sites around 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.

The OASIS trial will build upon a foundation of knowledge and infrastructure developed through the UNC-led, $40 million AURORA initiative. AURORA is a major national research initiative to improve the understanding, prevention, and recovery of individuals who experience a traumatic event. AURORA is supported by funding from the National Institutes of Health (NIH), leading brain health nonprofit One Mind, private foundations, and partnerships with leading tech companies such as Mindstrong Health and Verily Life Sciences, the healthcare arm of Alphabet, the parent company of Google.

“This innovative clinical trial and partnership will help address the need for safe and effective therapies to treat acute trauma,” said Samuel McLean, M.D., Professor of Psychiatry and Emergency Medicine at the UNC School of Medicine at UNC, School of Medicine, and lead principal investigator of the proposed study. “ASR and posttraumatic stress symptoms are common among civilian motor vehicle collision survivors. The AURORA initiative, which has collected thousands of data points from motor vehicle collisions, has allowed us to better investigate the correlation between motor vehicle collisions and the emergence of acute stress disorder or PTSD symptoms. In OASIS, we will test a pharmacological intervention in the immediate aftermath of trauma that has potential for fast relief of stress symptoms, improvement in coping and functioning, and preclusion of escalation to more severe conditions, ASD in the short term and PTSD thereafter.”

Acute and chronic stress disorders can affect both civilian and military populations. According to the National Center for PTSD, in the U.S. about 60% of men and 50% of women experience at least one trauma in their lives.⁴ In the U.S. alone, one-third of emergency department visits (40-50 million patients per year) involve evaluation after trauma exposures, and in a 2014 study involving 3,157 US veterans, 87% reported exposure to at least one potentially traumatic event during their service.⁵ Moreover, as many as 500,000 U.S. troops who served in wars between 2001 and 2015 were diagnosed with PTSD.⁶

Long COVID shares symptoms with chronic overlapping pain disorders like fibromyalgia and appears mechanistically related

Tonix is studying TNX-102 SL for both the management of fibromyalgia and management of fibromyalgia-type Long COVID.

CHATHAM, N.J., Jan. 31, 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 and currently focused on preparing a New Drug Application (NDA) for Tonmya (formerly TNX-102 SL, sublingual cyclobenzaprine HCl) for the management of fibromyalgia, today 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. The TriNetX Analytics platform was used to extract anonymized electronic health record data from more than 91 million people in the U.S. These findings showed that: (1) in addition to COVID, prolonged pain may occur after recovery from viral infections like influenza, (2) people with pre-existing pain are at risk for exacerbation of their pain after viral illness, (3) pre-existing COPCs increase the risk of Long COVID, and (4) COPCs and Long COVID likely result from the same or similar brain processes, and Long COVID can be conceptualized as a new onset COPC or an exacerbation of a pre-existing COPC.

“These results contribute to a growing body of evidence that most symptoms of Long COVID are at least partly driven by central nervous system mechanisms rather than persistent exposure to the SARS-CoV-2 virus,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Tonix is studying TNX-102 SL for the management of fibromyalgia (conditionally approved by U.S. Food and Drug Administration as “Tonmya”) and for fibromyalgia-type Long COVID. Fibromyalgia is already recognized as a COPC. The new paper adds to the growing body of evidence that many cases of Long COVID should be viewed in the COPC framework, rather than in a purely post-infectious disease perspective.”

Dr. Lederman continued, “In the post-pandemic era, in which COVID is endemic and repeated bouts are common, it will be important to learn if appropriate management of fibromyalgia may reduce the risk of developing Long COVID. Moreover, since fibromyalgia symptoms like widespread pain were risk factors for COVID even without a diagnosis of fibromyalgia, these findings suggest that earlier diagnosis and management of fibromyalgia may be advised.”

“The magnitude of Long COVID risk conferred by a pre-existing COPC was comparable with, if not larger than, that for sex and acute COVID hospitalization status, which are known risk factors for Long COVID,” ^2,3 said Rachael Bergmans, M.P.H, Ph.D., Research Assistant Professor at the University of Michigan Medical School Department of Anesthesiology, Chronic Pain and Fatigue Research Center (CPFRC) and lead author of the paper. “These findings are consistent with previous research where pre-existing chronic pain conditions including fibromyalgia, back pain, and migraine increase the risk of Long COVID.”^2-4

Tonmya* has shown positive results in two Phase 3 clinical trials for the management of fibromyalgia. Tonix plans to submit an NDA to the U.S. Food and Drug Administration in the second half of 2024 under the 505(b)(2) regulatory pathway for Tonmya for the management of fibromyalgia.

Phase 1/2 Clinical Trial of TNX-801 for the Prevention of Mpox and Smallpox to Commence Following Submission of an IND

TNX-801 is Based on a Proprietary Live Virus Vaccine Platform Designed to Stimulate Durable T-Cell Immunity

TNX-801 Vaccination Protected Animals from a Lethal Challenge with Monkeypox in Preclinical Testing

CHATHAM, N.J., Aug. 21, 2023 (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 received the 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-801¹ (recombinant horsepox virus, live vaccine) 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.

“The FDA’s response to the pre-IND meeting marks an important milestone in the development of TNX-801 since we have FDA concurrence on the proposed manufacturing, toxicology studies, and the Phase 1/2 clinical design,” said Seth Lederman, M.D., President and Chief Executive Officer of Tonix. “TNX-801 is believed to be closely related to Edward Jenner’s original smallpox vaccine.^2-10 Jenner’s live virus smallpox vaccine – the first vaccine – remains one of the most effective vaccines in history, since it typically provided lifetime immunity with a single dose, prevented forward transmission of the smallpox virus, and ultimately eradicated the disease. TNX-801 has an attenuated phenotype relative to modern vaccinia viruses, which comprise a group of vaccine viruses that evolved from Jenner’s vaccine during passage in man and animals for over 100 years. When live virus vaccinia vaccination was routinely practiced in Africa, mpox was kept out of the human population.”^2,11

TNX-801 is a live replicating attenuated vaccine based on horsepox that is believed to protect against smallpox and mpox, primarily by eliciting a T-cell response evidenced by the “take”. The “take” is a functional measure of protective T-cell immunity validated by the eradication of smallpox. TNX-801 is administered with a single dose, can be readily scaled up for manufacturing using proven technology and can be distributed and stored without requiring a costly and cumbersome ultra-cold supply chain. Live replicating vaccines have the potential to induce durable T-cell immunity, prevent serious illness after infection and block forward transmission. Tonix reported positive preclinical efficacy data, demonstrating that TNX-801 vaccination protected non-human primates against lethal challenge with mpox.¹²

“More than 30,000 people have contracted mpox in the U.S. so far during the 2022-23 epidemic,”¹³ said Dr. Zeil Rosenberg, Executive Vice President, Medical at Tonix. “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.¹⁴ In contrast, TNX-801 is delivered intradermally 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 vaccine to meet global health needs, especially in Africa.”

Dr. Rosenberg added, “We believe TNX-801 could make a global impact on mpox and the risk of smallpox because of its potential durable T-cell immune response, the ability to manufacture at scale, to use a lower dose than non-replicating vaccines. The current formulation is a frozen liquid, but we believe that future lyophilized versions can be stored and shipped at standard refrigeration. Moreover, we believe the low dose of TNX-801 makes this technology amenable for future implementation in microneedle delivery systems.”

Dr. Lederman concluded, “In addition to its potential use as a vaccine, TNX-801 also has the potential as a viral vector platform, for which versions can be developed to protect against a host of infectious diseases beyond smallpox and mpox, including COVID-19. In light of the recent resurgence in COVID cases across the country with the new EG.5 “Eris” variant, we believe that the horsepox recombinant pox virus platform may provide next generation vaccines to prevent future outbreaks.”

About TNX-801*
TNX-801 is a live virus vaccine based on horsepox^2,11. Horsepox and vaccinia are closely related orthopoxviruses that are believed to share a common ancestor. TNX-801 is believed to be more closely related to Jenner’s vaccinia vaccine than modern vaccinia vaccines, which appear to have evolved by deletions and mutations to a phenotype of larger plaque size in tissue culture and greater virulence in mice. Molecular analysis shows that horsepox is closer than modern vaccinia vaccines in DNA sequence to the vaccine discovered and disseminated by Dr. Edward Jenner.^2-10 Vaccine genome researchers have recently shown the contemporaneous use of horsepox and horsepox-related viruses in the United States as smallpox vaccines in the 1860’s^9,10. Additionally they found a remarkable degree of identity with the circa 1860 U.S. smallpox vaccine VK05 and the 1976 Mongolian horsepox isolate called MNR-76, upon which Tonix’s TNX-801 is based.^3,5 These recent discoveries are further steps in establishing that what is called ’horsepox‘ today was used to vaccinate against smallpox in the 19^th century. Dr. Edward Jenner invented vaccination in 1798 and the procedure was called “vaccination” because the inoculum material was initially obtained from lesions on the udders of cows affected by a mild disease known as cowpox². ‘Cow’ is ‘vacca’ in Latin. However, Dr. Jenner suspected that cowpox originated from horsepox.² 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’. Equination and vaccination were practiced side-by-side in Europe⁶. The small plaque size in culture of TNX-801 appears identical to the U.S. Centers for Disease Control publication of the natural isolate¹². Relative to vaccinia, horsepox has substantially decreased virulence in mice³. Tonix’s TNX-801 vaccine candidate is administered intradermally. 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.

Single Ascending Dose Escalation Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of TNX-1500

Study Designed to Support Planned Phase 2 Trial in Prevention of Kidney Transplant Rejection

Multiple Possible Indications, Including Bone Marrow Transplantation and Autoimmune Diseases: Potential Pipeline in a Product

TNX-1500 is the First of Tonix’s Internally-Developed Biologic Candidates to Reach the Clinic

CHATHAM, N.J., Aug. 16, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP), a biopharmaceutical company with marketed products and a pipeline of development candidates, today announced the initiation of a Phase 1 single ascending dose escalation study of TNX-1500 (Fc-modified humanized anti-CD40L monoclonal antibody or mAb) in healthy volunteers. The primary objectives of the study are to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of intravenous (IV) TNX-1500.

TNX-1500 is in development for the prevention of kidney transplant rejection and other potential transplant and autoimmune disorder indications. Recent animal studies indicate that TNX-1500 prevents organ rejection and preserves graft function either as a single agent or in combination with other drugs.^1,2 Eligible participants enrolled in the Phase 1 study will be evaluated regularly over a 120-day period after dosing. Target enrollment is 36 participants. Initiation of this first-in-human study is intended to support dosing in a planned Phase 2 trial in kidney transplant recipients.

“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. “TNX-1500 has demonstrated single agent activity for long-term organ acceptance and induction of tolerance in animals.^1,2 Potentially related to its activity, in preclinical studies, TNX-1500 preserves T regulatory cells, or Tregs, which are key to maintaining tolerance to grafts as well as to self-antigens. We believe TNX-1500 has the potential to prevent organ transplant rejection and improve long-term graft survival with reduced long-term toxicity burden compared to current immunosuppressive regimens. In addition, TNX-1500 has the potential to address multiple indications, including a number of autoimmune diseases. The range of potential indications suggests ‘pipeline in a product’ potential.”

“We are excited to advance TNX-1500 into the clinic by initiating this Phase 1 trial,” said Dr. Greg Sullivan, Chief Medical Officer of Tonix. “TNX-1500 is a third generation anti-CD40L mAb that has been designed by protein engineering to decrease FcγRIIA binding. Preclinical studies in non-human primates demonstrated that TNX-1500 is active in preventing allograft organ rejection and is well tolerated. Specifically, thrombotic complications associated with first generation anti-CD40L mAbs, were not observed, suggesting that the protein engineering underlying TNX-1500 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,³ and from Horizon Therapeutics plc with its tn03 fusion protein dazodalibep in treating Sjögren’s syndrome.^4,5   UCB is in Phase 3 development with its anti-CD40L pegylated Fab, dapirolizumab pegol, for the treatment of systemic lupus erythematosus.⁶ Based on results from animals, we consider Fc-modified humanized TNX-1500 to be a potential best-in-class therapeutic in the CD40L blocker space.”  

CD40L is a member of the TNF-α superfamily, which includes TNF-α and RANKL. TNF-α is the target for several established drugs, including Humira^® (adalimumab), Remicade^® (infliximab), Enbrel^® (etanercept), and Cimzia® (certolizumab). RANKL is targeted by Prolia^® and Xgeva^® (denosumab). Emerging TNF-α superfamily targets for therapeutics include TL1A, CD30L, Ox40L, and 41BBL. Merck acquired Prometheus Biosciences for its anti-TL1A and anti-CD30L programs.

Dr. Lederman concluded, “TNX-1500 is the first of Tonix’s internally-developed biologic candidates to reach the clinic. Tonix owns worldwide rights to TNX-1500, which are unencumbered by royalties. Our ability to develop and advance protein therapeutics is facilitated by our Research and Development Center (RDC) in Frederick, Md. and our Advanced Development Center (ADC) in Dartmouth, Mass.”

About TNX-1500

TNX-1500 (Fc-modified humanized 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 was initiated in the third quarter of 2023. Two articles have recently published in the American Journal of Transplantation that demonstrate TNX-1500 prolongs non-human primate renal and heart allograft survival^1,2.
