Combination treatment of mTNX-1700 (mTFF2-MSA fusion protein) with anti-PD1 antibody was associated with increased survival and decreased metastases in animal models of gastric cancer relative to anti-PD1 treatment alone

mTNX-1700 treatment was associated with activation of cancer-killing CD8+ T Cells and limiting neutrophil-mediated immune evasion

TNX-1700 (hTFF2-HSA fusion protein) is in preclinical development for gastric and colorectal cancers

CHATHAM, N.J., July 02, 2025 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a fully-integrated biopharmaceutical company with marketed products and a pipeline of development candidates, today announced the publication of a paper entitled, “A CXCR4 Partial Agonist, Improves Immunotherapy by Targeting Immunosuppressive Neutrophils and Cancer-Driven Granulopoiesis,”1 in the peer-reviewed journal Cancer Cell, that represents a collaboration between scientists at Tonix and Columbia University’s Medical School and presents data demonstrating that treatment with murine TNX-1700 (mTNX-1700) increased survival and decreased metastases in animal models of gastric cancer. The manuscript can be accessed here: http://bit.ly/3I7Wcvu.

“Addressing the root causes of resistance to immunotherapy in solid tumors is a hurdle for the successful application of immuno-oncology to anti-PD-1 resistant cancers,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “The combination therapy of mTFF2-MSA with anti-PD1 treatment shows significant promise in reducing the ability of tumors to evade anti-PD-1 therapy in animal models. We believe the published data support further development of TNX-1700 as an approach to overcome resistance to anti-PD-1 immunotherapy in the treatment of gastric cancer and other tumors.”

The published studies examined mTNX-1700, which is a fusion protein of murine trefoil factor-2 (mTFF2) and murine serum albumin (MSA). The human version, TNX-1700 is a fusion protein of human TFF2 (hTFF2) and human serum albumin (HSA) that is under development for the treatment of gastric and colorectal cancers.

Dr. Lederman added, “The study showed that in several mouse models, mTNX-1700 plus anti-PD-1 shrank primary tumors, cut liver and lung metastases, and increased survival compared to anti-PD-1 alone. These data show that fine-tuned modulation of CXCR4 can dismantle neutrophil-driven immune suppression and revive checkpoint efficacy without compromising normal myelopoiesis. We are excited, through our collaboration with Columbia University, to continue studies to identify potential clinical biomarkers through preclinical models while enhancing our understanding of the relationship between the role of TFF2 in overcoming resistance to anti-PD1 therapy in the tumor microenvironment (TME).”

Immunosuppressive neutrophils, also known as polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs), are a major component in solid tumors that significantly hinder anti-tumor activity2,3. Despite being short-lived, the continuous replenishment of PMN-MDSCs from the bone marrow sustains their potent immunosuppression in the TME4. Stromal cells in the TME promote immunosuppression by recruiting MDSCs via secretion of CXCL12. Trefoil Factor 2 (TFF2), a secreted peptide of the trefoil factor family, has displayed activity as a partial agonist of CXCR45,6. The Cancer Cell publication describes data demonstrating that TFF2-MSA selectively reduces immunosuppressive neutrophils and cancer-driven granulopoiesis. Treatment with TFF2-MSA, in combination with an anti-PD1 antibody, induced robust anti-tumoral CD8+ T cell responses, inhibiting tumor invasion. This combination of the mTNX-1700 with anti-PD1 therapy has been shown to reduce tumor size and increase survival in these animal models. TFF2 reduction correlated with elevated PMN-MDSCs in gastric cancer patients, highlighting the potential negative correlation between TFF2 and PMN-MDSCs levels while promoting a T-cell rich microenvironment and inducing an increase in CD8+ T cells in the tumor.

About Trefoil Factor Family Member 2 (TFF2)

Human TFF2 is a secreted protein, encoded by the TFF2 gene in humans, that is expressed in gastrointestinal mucosa where it functions to protect and repair mucosa. TFF2 is also expressed at low levels in splenic immune cells and is now appreciated to have intravascular roles in the spleen and in the tumor microenvironment. In gastric cancer, TFF2 is epigenetically silenced, and TFF2 is suggested to be protective against cancer development through several mechanisms. Tonix is developing TNX-1700 for the treatment of gastric and colorectal cancers under a license from Columbia University. The inventor of the core technology at Columbia is Dr. Timothy Wang, who is an expert in the molecular mechanisms of carcinogenesis whose research has focused on the carcinogenic role of inflammation in modulating stem cell functions. Dr. Wang demonstrated that knocking out the mTFF2 gene in mice leads to faster tumor growth and that overexpression of TFF2 markedly suppresses tumor growth by curtailing the homing, differentiation, and expansion of MDSCs to allow activation of cancer-killing CD8+ T cells. He went on to show that a novel engineered form of recombinant murine TFF2 (mTFF2-CTP) had an extended half-life in vivo and was able to suppress MDSCs and tumor growth in an animal model of colorectal cancer. Later, he showed in gastric cancer models that suppressing MDSCs using chemotherapy enhances the effectiveness of anti-PD1 therapy and significantly reduces tumor growth. Dr. Wang proposed the concept of employing recombinant TFF2 in combination with other therapies in cancer prevention and early treatment.

Release – Tonix Pharmaceuticals Presented Data and Analyses of TNX-102 SL Treatment Effects on Fibromyalgia at the Annual European Congress of Rheumatology (EULAR) 2025

Research News and Market Data on TNXP

June 16, 2025 7:00am EDT Download as PDF

TNX-102 SL is a sublingual formulation of cyclobenzaprine designed for transmucosal delivery and durable activity in treating fibromyalgia: FDA PDUFA goal date of August 15, 2025

TNX-102 SL demonstrated statistically significant improvement in the primary endpoint of reduction in fibromyalgia pain in two double-blind randomized placebo-controlled Phase 3 studies

If approved by FDA, TNX-102 SL would become the first member of a new class of non-opioid analgesic drugs for fibromyalgia and the first new drug for treating fibromyalgia in more than 15 years

CHATHAM, N.J., June 16, 2025 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company) presented data in a poster presentation at the Annual European Congress of Rheumatology (EULAR) 2025, held June 11-14, 2025, in Barcelona, Spain. A copy of the Company’s poster, titled “Advancing Fibromyalgia Treatment: Transmucosal Sublingual Cyclobenzaprine (TNX-102 SL) Targets Non-restorative Sleep and Provides Sustained Pain Reduction” is available under the Scientific Presentations tab of the Tonix website at www.tonixpharma.com. TNX-102 SL (cyclobenzaprine HCl sublingual tablets) is a non-opioid analgesic designed for daily bedtime dosing with an FDA Prescription Drug User Fee Act (PDUFA) goal date of August 15, 2025.

“Fibromyalgia is a complex and invisible chronic pain condition which drives many patients to be prescribed chronic opioids which are associated with addiction and overdose,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “To address the chronic symptoms of fibromyalgia, potential therapeutic options must provide durable benefits. TNX-102 SL has shown statistically significant, durable activity (14 weeks) in reducing fibromyalgia pain in two Phase 3 studies. Designed to target the sleep disturbance of fibromyalgia, TNX-102 SL harnesses the therapeutic activity of cyclobenzaprine in part by reducing in the level of the active metabolite norcyclobenzaprine relative to oral cyclobenzaprine. Norcyclobenzaprine is believed to interfere with the durability of oral cyclobenzaprine’s treatment effect in off-label chronic dosing regimens and in a failed double-blind randomized placebo-controlled trial.1 TNX-102 SL now has the potential to be the first new treatment option for fibromyalgia patients in 15 years.”

TNX-102 SL is designed for transmucosal absorption to bypass first-pass hepatic metabolism. The poster presentation shows the day 20 steady state blood levels from a study of nightly TNX-102 SL dosing in which the peak level of cyclobenzaprine exceeds the level of the active metabolite norcyclobenzaprine during sleep time. In contrast, with nightly oral cyclobenzaprine dosing, pharmacokinetic simulations show that norcyclobenzaprine accumulates to higher levels, and the cyclobenzaprine peak level does not exceed the norcyclobenzaprine level during sleep time.

The poster includes data from the RESILIENT Phase 3 study evaluating the efficacy and safety of TNX-102 SL with a primary endpoint of reducing daily pain numeric rating scale scores after 14 weeks of treatment. TNX-102 SL significantly reduced pain and improved clinical outcomes in fibromyalgia patients while demonstrating a favorable tolerability profile. TNX-102 SL employs a novel mechanism targeting the sleep disturbance in fibromyalgia by acting as a potent antagonist at four post-synaptic receptors, each of which is known to regulate sleep.

About Fibromyalgia

Fibromyalgia is a common chronic pain disorder that is understood to result from amplified sensory and pain signaling within the central nervous system, called central sensitization. Brain imaging studies have localized the functional disorder to the brain’s insula and anterior cingulate cortex. Fibromyalgia afflicts more than 10 million adults in the U.S., the majority of whom are women. Symptoms of fibromyalgia include chronic widespread pain, non-restorative sleep, fatigue, and brain fog (or cognitive dysfunction). Other associated symptoms include mood disturbances, including depression, anxiety, headaches and abdominal pain or cramps. Individuals suffering from fibromyalgia often struggle with their daily activities, have impaired quality of life, and frequently are disabled. Physicians and patients report common dissatisfaction with currently marketed products. Fibromyalgia is now recognized as the prototypic nociplastic syndrome. Nociplastic pain is the third primary type of pain in addition to nociceptive pain and neuropathic pain. Many patients present with pain syndromes that are mixtures of the three primary types of pain. Nociplastic syndromes are associated with central and peripheral sensitization. Fibromyalgia can occur without any identifiable precipitating event. However, many fibromyalgia cases follow one or more precipitating event(s) including: post-operative pain, acute or chronic nociceptive or neuropathic pain states; recovery from an infectious illness; a cancer diagnosis or cancer treatment; a metabolic or endocrine stress; or a traumatic event. In the cases of recovery from an infectious illness, fibromyalgia is considered an Infection-Associated Chronic Condition. In addition to fibromyalgia cases associated with other conditions or stressors, the U.S. National Academies of Sciences, Engineering, and Medicine, has concluded that fibromyalgia is a diagnosable condition that can occur after recovery from COVID-19 in the context of Long COVID.

About TNX-102 SL

TNX-102 SL is a centrally acting, non-opioid investigational drug, designed for chronic use. The tablet is a patented sublingual formulation of cyclobenzaprine hydrochloride developed for bedtime dosing for the management of fibromyalgia. Cyclobenzaprine potently binds and acts as an antagonist at four different post-synaptic neuroreceptor subtypes: serotonergic-5-HT2A, adrenergic-α1, histaminergic-H1, and muscarinic-M1-cholinergic receptors. Together, these interactions are believed to target the non-restorative sleep characteristic of fibromyalgia identified by Professor Harvey Moldofsky in 1975.   Cyclobenzaprine is not associated with risk of addiction or dependence. The TNX-102 SL tablet is based on a eutectic formulation of cyclobenzaprine HCl and mannitol that provides a stable product which dissolves rapidly and delivers cyclobenzaprine by the transmucosal route efficiently into the bloodstream. The eutectic protects cyclobenzaprine HCl from interacting with the basifying agent that is also part of the formulation and required for efficient transmucosal absorption. Patents based on TNX-102 SL’s eutectic composition and its properties have issued in the U.S., E.U., Japan, China and many other jurisdictions around the world and provide market protection into 2034. The European Patent Office’s Opposition Division maintained Tonix’s European Patent EP 2 968 992 in unamended form after an Opposition was filed against it by a Sandoz subsidiary, Hexal AG. Hexal AG did not appeal that decision. The formulation of TNX-102 SL was designed specifically for sublingual administration and transmucosal absorption for bedtime dosing to target disturbed sleep, while reducing the risk of daytime somnolence. Clinical pharmacokinetic studies indicated that relative to oral cyclobenzaprine, TNX-102 SL results in higher levels of exposure during the first 2 hours after dosing and in deceased levels of the long-lived active metabolite, norcyclobenzaprine in both single dose and multiple dose studies, consistent with bypassing first pass hepatic metabolism. Cyclobenzaprine is a tertiary amine tricyclic and its active metabolite norcyclobenzaprine is a secondary amine tricyclic. At steady state after 20 days of dosing TNX-102 SL, the dynamic peak level of cyclobenzaprine is higher than the background level of norcyclobenzaprine during sleep time. In contrast, after 20 days of dosing oral cyclobenzaprine, the simulated peak level of cyclobenzaprine is lower than the simulated background level of norcyclobenzaprine.

Release – Tonix Pharmaceuticals Announces First Patient Dosed in Phase 2 OASIS Study of TNX-102 SL for Reduction of Acute Stress Reaction

Research News and Market Data on TNXP

May 21, 2025 7:00am EDT Download as PDF

Investigator-initiated Phase 2 trial to evaluate TNX-102 SL’s potential to reduce severity of acute stress reaction (ASR) and frequency of acute stress disorder (ASD)

Trial is sponsored by the University of North Carolina (UNC) and supported by a grant from the U.S. Department of Defense

Topline results from the trial are expected in the second half of 2026

CHATHAM, N.J., May 21, 2025 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP), a fully-integrated biotechnology company with marketed products and a pipeline of development candidates, today announced the first patient has been dosed in the Phase 2, investigator-initiated OASIS trial to evaluate TNX-102 SL in reducing the severity of acute stress reaction (ASR) and the frequency of acute stress disorder (ASD). 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).

“TNX-102 SL has been shown to improve sleep quality in PTSD, and previous trials of TNX-102 SL suggested activity on sleep and stress-related symptoms in the first several weeks of treatment,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Addressing sleep disturbances is crucial in managing ASR, as poor sleep can exacerbate other symptoms and hinder recovery. There is a significant unmet need for treating ASR after traumatic events, such as civilian motor vehicle collisions or warfighter experiences in forward bases or in theater. We are encouraged by the support of TNX-102 SL’s prior data improving PTSD symptomatology in the first several weeks of treatment, which may be crucial to reducing ASR symptoms and their sequalae. We look forward to topline results in the second half of 2026.”

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 (MVC). The trial plans to enroll approximately 180 MVC-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.

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 In the U.S. alone, one-third of ED 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. Moreover, as many as 500,000 U.S. troops who served in wars between 2001 and 2015 were diagnosed with PTSD. Currently, no medication is available in the immediate aftermath of traumatic events to treat the initial reaction and support long term health via a post-trauma clinical trajectory that prevents development or worsening of ASD, thereby also preventing PTSD.

About TNX-102 SL

TNX-102 SL is a centrally acting, non-opioid investigational drug, designed for chronic use. The tablet is a patented sublingual formulation of cyclobenzaprine hydrochloride developed for bedtime dosing for the management of fibromyalgia. Cyclobenzaprine potently binds and acts as an antagonist at four different post-synaptic neuroreceptor subtypes: serotonergic-5-HT2A, adrenergic-α1, histaminergic-H1, and muscarinic-M1-cholinergic receptors. Together, these interactions are believed to target the non-restorative sleep characteristic of fibromyalgia identified by Professor Harvey Moldofsky in 1975. Cyclobenzaprine is not associated with risk of addiction or dependence. The TNX-102 SL tablet is based on a eutectic formulation of cyclobenzaprine HCl and mannitol that provides a stable product which dissolves rapidly and delivers cyclobenzaprine by the transmucosal route efficiently into the bloodstream. The eutectic protects cyclobenzaprine HCl from interacting with the basifying agent that is also part of the formulation and required for efficient transmucosal absorption. Patents based on TNX-102 SL’s eutectic composition and its properties have issued in the U.S., E.U., Japan, China and many other jurisdictions around the world and provide market protection into 2034. The European Patent Office’s Opposition Division maintained Tonix’s European Patent EP 2 968 992 in unamended form after an Opposition was filed against it by a Sandoz subsidiary, Hexal AG. Hexal AG did not appeal that decision. The formulation of TNX-102 SL was designed specifically for sublingual administration and transmucosal absorption for bedtime dosing to target disturbed sleep, while reducing the risk of daytime somnolence. Clinical pharmacokinetic studies indicated that relative to oral cyclobenzaprine, TNX-102 SL results in higher levels of exposure during the first 2 hours after dosing and in deceased levels of the long-lived active metabolite, norcyclobenzaprine in both single dose and multiple dose studies, consistent with bypassing first pass hepatic metabolism. At steady state after 20 days of dosing TNX-102 SL, the dynamic peak level of cyclobenzaprine is higher than the background level of norcyclobenzaprine. In contrast, after 20 days of dosing oral cyclobenzaprine, the simulated peak level of cyclobenzaprine is lower than the simulated background level of norcyclobenzaprine.

Release – Tonix Pharmaceuticals Reports First Quarter 2025 Financial Results and Operational Highlights

Research News and Market Data on TNXP

May 12, 2025 4:30pm EDT

FDA PDUFA goal date of August 15, 2025, for TNX-102 SL for the management of fibromyalgia; if approved, TNX-102 SL would become the first new drug for treating fibromyalgia in more than 15 years

Announced positive topline results from Phase 1 study of TNX-1500, a next generation anti-CD40L mAb candidate in development for prevention of kidney transplant rejection and treatment of autoimmune disorders

Cash and cash equivalents of $131.7 million reported as of March 31, 2025; Current cash sufficient to fund operations into the second quarter of 2026

CHATHAM, N.J., May 12, 2025 (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, 2025, and provided an overview of recent operational highlights.

“We believe TNX-102 SL (cyclobenzaprine HCl sublingual tablets)* is on track to become a new therapeutic option for patients suffering with fibromyalgia,” said Seth Lederman, M.D., Chief Executive Officer of Tonix. “TNX-102 SL would be the first member of a new class of FDA approved drugs for fibromyalgia. TNX-102 SL is a non-opioid analgesic that targets fibromyalgia’s characteristic disturbed sleep to improve the widespread pain of fibromyalgia, while also being well tolerated. Our focus continues to be on the upcoming U.S. Food and Drug Administration (FDA) Prescription Drug User Fee Act (PDUFA) goal date of August 15, 2025, for a decision on the market authorization on TNX-102 SL for the management of fibromyalgia. We are building out our commercial team for the anticipated product launch in the fourth quarter of this year. Tonix believes it has sufficient cash to fund operations beyond these key milestones.”

Dr. Lederman continued, “Beyond TNX-102 SL for fibromyalgia, we are encouraged by the continued achievements in our pipeline, including positive Phase 1 results for TNX-1500, a next generation anti-CD40L Fc-modified humanized monoclonal antibody (mAb) in development for prevention of kidney transplant rejection and pre-clinical results for TNX-801, a live-virus vaccine in development for preventing mpox and smallpox. We look forward to providing additional updates to each of these promising programs in 2025.”

Key Investigational Product Candidates* — Recent Highlights

Central Nervous System (CNS) Pipeline

TNX-102 SL (cyclobenzaprine HCl sublingual tablets): 5.6 mg, once-daily at bedtime small molecule for the management of fibromyalgia (FM) – a centrally-acting, non-opioid analgesic.

  • In March 2025, Tonix announced that FDA will not require an Advisory Committee meeting to discuss the Company’s New Drug Application (NDA) for TNX-102 SL for the management of fibromyalgia. The FDA previously granted Fast Track designation to TNX-102 SL for the management of fibromyalgia in 2024, a designation intended to expedite FDA review of important new drugs to treat serious conditions and fill an unmet medical need.
  • In December 2024, the NDA for TNX-102 SL for fibromyalgia was accepted by FDA with a PDUFA goal date of August 15, 2025. The NDA was based upon two Phase 3 studies of TNX-102 SL in fibromyalgia that showed statically significant reduction in the chronic, widespread pain associated with fibromyalgia. TNX-102 SL was generally well tolerated and has no known addictive properties. If approved by the FDA, TNX-102 SL would be the first member of a new class of tertiary amine tricyclic (TAT) non-opioid analgesic drugs for fibromyalgia and the first new drug available for treating fibromyalgia in more than 15 years. Fibromyalgia affects more than 10 million adults in the U.S., most of whom are women.
  • In April 2025, Tonix presented data and analyses of TNX-102 SL treatment and effects on fibromyalgia at the American Academy of Pain Medicine (AAPM) 2025 Annual Meeting, held in Austin, Texas, in a poster presentation titled, “Sublingual Cyclobenzaprine (TNX-102 SL) for Fibromyalgia: Efficacy and Safety in Two Randomized, Placebo-Controlled Trials.
  • In March 2025, the Company presented data and analyses of TNX-102 SL treatment and effects on fibromyalgia at the 7th International Congress on Controversies in Fibromyalgia, held in Vienna, Austria, in an oral presentation titled, “Transmucosal Sublingual Cyclobenzaprine (TNX-102 SL) Treatment of Fibromyalgia at Bedtime to Target Non-Restorative Sleep Showed Durable Pain Reduction in Two Double-Blind Randomized Phase 3 Studies.

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

  • The U.S. Department of Defense-funded Optimizing Acute Stress Reaction Interventions (OASIS) trial will be conducted by the University of North Carolina under an investigator-initiated investigational new drug (IND) application. The OASIS trial will examine the safety and efficacy of TNX-102 SL to reduce adverse posttraumatic neuropsychiatric sequelae among patients in the emergency department (ED) after a motor vehicle collision. Fourteen days of bedtime TNX-102 SL will be dosed and tested in the immediate aftermath of motor vehicle collision. The study will test the potential for TNX-102 SL to target trauma-related sleep disturbance and its ability to facilitate recovery from ASR and to prevent PTSD. The program has the potential to provide military personnel with a new treatment option that improves warfighter performance and resilience when administered in the early aftermath of traumatic events in the war theater. The study is expected to be initiated in the second quarter of 2025.

TNX-1300 (recombinant double mutant cocaine esterase): under investigation for biologic for cocaine intoxication

  • The National Institutes of Health (NIH)’s National Institute of Drug Abuse (NIDA) previously awarded Tonix a Cooperative Agreement grant for approximately $5 million to support development of TNX-1300.
  • TNX-1300 has been granted Breakthrough Therapy designation by the FDA.
  • The Company discontinued enrollment and terminated the Phase 2 CATALYST study of its TNX-1300 double-mutant cocaine esterase 200 mg, i.v. solution product candidate for the treatment of cocaine intoxication because enrollment in this emergency department-based study was slower than projected. The Company is evaluating new study designs and new endpoints for further development of TNX-1300. The CATALYST study was not discontinued for safety or efficacy reasons.

Immunology Pipeline

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

  • In February 2025, Tonix announced positive topline results from its Phase 1, single ascending dose (SAD) first-in-human trial of TNX-1500 in healthy participants. The objectives of the Phase 1 trial were to assess the safety, tolerability, pharmacokinetics, and pharmacodynamics of intravenous TNX-1500, as well as to support dosing in a planned Phase 2 trial in kidney transplant recipients, pending alignment with the FDA. All objectives were met and support proceeding to a Phase 2 trial. TNX-1500 blocked the primary and secondary antibody responses to a test antigen at the 10 mg/kg and 30 mg/kg i.v. doses, showed mean half-life of 34-38 days for the 10 mg/kg and 30 mg/kg doses (supporting monthly dosing for future efficacy trials) and was generally well-tolerated with a favorable safety profile.
  • 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 the treatment of autoimmune diseases. Preclinical studies have shown that TNX-1500 maintains the activity of first-generation monoclonal antibodies (mAbs), yet with reduced risk of thrombotic complications.   Pharmacokinetic data support a monthly i.v. dosing regimen. This analysis together with TNX-1500’s activity and tolerability in animal models, suggests that the protein engineering of TNX-1500’s Fc region has achieved its design goals.

Infectious Disease Pipeline

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

  • In April 2025, the company presented data on TNX-801 in an oral presentation at the World Vaccine Congress Washington 2025, held in Washington, D.C. The presentation titled “A Novel Single-Dose, Attenuated Live, Minimally Replicative Mpox Vaccine” highlighted positive preclinical efficacy data, demonstrating that TNX-801 protected animals from mpox and rabbitpox and was well tolerated, even in immunocompromised animals. Durable protection of rabbits from lethal rabbitpox infection was present six months after vaccination. In September 2024, Tonix announced that the WHO’s preferred target product profile (TPP), released at the WHO sponsored Mpox Research and Innovation Scientific Conference, aligns with the characteristics of TNX-801.
  • In March 2025, Tonix announced it was awarded a grant from the Medical CBRN Defense Consortium (MCDC) to support the development of TNX-801. The grant will allow Tonix to develop a commercialization plan for TNX-801.

Corporate and Partnerships – Recent Highlights*

  • In April 2025, the Company announced it has entered into a collaborative research agreement with Makana Therapeutics, a global leader in the field of xenotransplantation, to study Tonix’s anti-CD40L (CD40 ligand, also called CD154) monoclonal antibody candidate, TNX-1500, in combination with Makana’s human-compatible pig organs and cells for the treatment of organ failure. TNX-1500 is an investigational, humanized Fc-modified IgG4 anti-CD40L antibody with high affinity for CD40L. The preclinical research and development collaboration has the potential to span multiple Makana programs including kidney, heart and islet cell xenotransplant.
  • In April 2025, Tonix announced the launch of TONIX ONE™, a fully-integrated digital platform designed to provide resources to help patients better understand and manage their migraine condition. TONIX ONE provides an intuitive, comprehensive journey for patients by offering educational resources about migraine and the limitations of oral medications which can sometimes lead to delayed or ineffective symptom relief. The platform also connects patients directly to independent migraine specialists via telehealth services and e-prescription requests, simplifying and accelerating access to treatment.  
  • During the first quarter of 2025, the Company announced the promotion of Siobhan Fogarty to Chief Technical Officer and the appointment of Gary Ainsworth as its new Vice President, Market Access.

      Financial – Recent Highlight

As of March 31, 2025, Tonix had $131.7 million of cash and cash equivalents, compared to $98.8 million as of December 31, 2024. Net cash used in operations was approximately $16.6 million for first quarter 2025, compared to net cash used in operations of $17.6 for the same period in 2024.

On July 30, 2024, the Company entered into a Sales Agreement with AGP pursuant to which the Company may issue and sell, from time to time, shares of the Company’s common stock having an aggregate offering price of up to $250.0 million in at-the-market sales. During the three months ended March 31, 2025, the Company sold approximately 2.7 million shares of common stock for net proceeds of approximately $59.8 million. Subsequent to March 31, 2025, the Company sold 0.6 million shares of common stock under the Sales Agreement, for net proceeds of approximately $9.9 million.

The Company believes that its cash resources at March 31, 2025, along with the net proceeds of $9.9 million raised from equity offerings in the second quarter of 2025, will meet its planned operating and capital expenditure requirements into the second quarter of 2026.

Subsequent to March 31, 2025, the Company repurchased 150,000 of its shares of common stock outstanding under a share repurchase program, for a gross aggregate cost of approximately $2.9 million.


First Quarter 2025 Financial Results

Net product revenue for the first quarter 2025 was approximately $2.4 million compared to $2.5 million for the same period in 2024. Net product revenue consisted of combined net sales of Zembrace® SymTouch® and Tosymra®. Cost of Sales for the first quarter 2025 was approximately $0.9 million compared to $1.7 million for the same period in 2024.

Research and development expenses for the first quarter 2025 were $7.4 million, compared to $12.9 million for the same period in 2024. This decrease is predominantly due to decreased clinical, non-clinical, manufacturing and employee-related expenses.

Selling, general and administrative expenses for the first quarter 2025 were $10.1 million, compared to $9.3 for the same period in 2024. The increase was primarily due to an increase in sales and marketing expenses offset by a decrease in employee-related expenses resulting from a reduction in workforce in earlier 2024.

Net loss available to common stockholders was $16.8 million, or $2.84 per share, basic and diluted, for the first quarter 2025, compared to net loss of $14.9 million, or $535.72 per share, basic and diluted, for the same period in 2024. The basic and diluted weighted average common shares outstanding for the first quarter 2025 was 5,927,231 compared to 27,886 shares for the same period in 2024.

Release – Tonix Pharmaceuticals Presented Data on Potential Mpox Vaccine TNX-801 at World Vaccine Congress Washington 2025

Research News and Market Data on TNXP

April 24, 2025 7:55am EDT Download as PDF

TNX-801 is a single-dose, live virus vaccine in development to protect against mpox and smallpox

TNX-801 protects immunocompromised animals from a lethal challenge with clade IIa monkeypox virus

Durability of TNX-801 vaccination shown by six-month protection of animals from a lethal challenge with rabbitpox

Tolerability of TNX-801 demonstrated in immunocompromised animals by no spreading to blood or tissues, even at high doses

CHATHAM, N.J., April 24, 2025 (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 data in an oral presentation at the World Vaccine Congress Washington 2025, held April 21-24, 2025, in Washington, D.C.   The presentation titled, “A Novel Single-Dose, Attenuated Live, Minimally Replicative Mpox Vaccine”, highlighted positive preclinical efficacy data, demonstrating that TNX-801 protected animals from mpox and rabbitpox and was well tolerated, even in immunocompromised animals. A copy of the Company’s presentation is available under the Scientific Presentations tab of the Tonix website at www.tonixpharma.com.

“TNX-801 shows promise as a potential mpox and smallpox vaccine by providing protective immunity to animals with a single-dose,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “TNX-801 was generally well tolerated, even in immunocompromised animals. The new data show durable six-month protection against a lethal challenge with rabbitpox virus and protection of immunocompromised animals against a lethal challenge with monkeypox clade IIa virus. These new data build upon prior studies showing protection of animals against a lethal challenge with intratracheal clade Ia mpox virus. In all of these studies, after a single dose vaccination, TNX-801 prevented both clinical disease and formation of lesions.”

Dr. Lederman continued, “The ongoing clade IIb mpox epidemic that started in 2022, and the more recent and ongoing clade Ib mpox epidemic, highlight the need for additional vaccine options, particularly single-dose options. Both the 2022 clade IIb and the 2024 clade Ib mpox epidemics have been declared by the World Health Organization (WHO) to be Public Health Emergencies of International Concern (PHEICs). We believe TNX-801 has the potential to make an impact towards preventing mpox and controlling future mpox epidemics.”

TNX-801 is a minimally replicative, live-virus vaccine based on synthesized horsepox that has been shown to provide single-dose immune protection against a monkeypox challenge with better tolerability than 20th century vaccinia live-virus vaccines in animals. In September 2024, Tonix announced that the WHO’s preferred target product profile (TPP), released at the WHO sponsored Mpox Research and Innovation Scientific Conference, aligns with the characteristics of TNX-801. Key elements of the WHO draft TPP include single-dose, durable protection, administration without special equipment, and stability at ambient temperature. Other potential beneficial characteristics include the ability to limit forward transmission, use in case-contact vaccination strategies and suitability for use in immunocompromised individuals.

About TNX-801*

TNX-801 (recombinant horsepox virus) is a single-dose, attenuated, minimally replicative, live virus vaccine based on horsepox in pre-clinical development to prevent mpox and smallpox. Tonix reported positive preclinical efficacy data, demonstrating that TNX-801 vaccination protected non-human primates against lethal challenge with monkeypox. After a single dose vaccination, TNX-801 prevented clinical disease and lesions and decreased shedding in the mouth and lungs of non-human primates. The findings are consistent with mucosal immunity and suggest the ability to block forward transmission, similar to Dr. Edward Jenner’s vaccine, which eradicated smallpox and kept mpox out of the human population. TNX-801 is based on synthesized horsepox which is believed to be more closely related to Dr. Jenner’s vaccine than 20th century vaccinia viruses.6 Smallpox vaccines descended from Jenner’s vaccine used prior to 1900 would be called horsepox by modern nomenclature. TNX-801 is delivered percutaneously with only one dose and therefore may achieve higher rates of community protection than two-dose vaccines by eliminating drop-out between doses and limiting forward transmission. Tonix has received official written response from a Type B pre-Investigational New Drug Application (IND) meeting with the U.S. Food and Drug Administration (FDA) to develop TNX-801 as a potential vaccine to protect against mpox disease and smallpox. Tonix has announced a collaboration with the Kenya Medical Research Institute (KEMRI) to design, plan and seek regulatory approval for a Phase I clinical study of TNX-801 in Kenya. The Company believes TNX-801 has the potential to make a global impact on mpox and the risk of smallpox because of its durable T-cell immune response, the potential to manufacture at scale, and the use of a lower dose than non-replicating vaccines. The FDA-approved non-replicating mpox vaccine Jynneos® requires two doses and provides a relatively short duration of protection. FDA also recently approved ACAM2000, a live, replicating vaccinia vaccine for prevention of mpox. ACAM200 is a clone from DryVax®, a 20th century vaccinia vaccine derived from the NYCBH strain. Pre-clinical results from an mRNA vaccine recently showed some protection from a Clade I monkeypox challenge, but with multiple break-through lesions in vaccinated animals.

Release – Tonix Pharmaceuticals Presented Data and Analyses of TNX-102 SL Treatment Effects on Fibromyalgia at the American Academy of Pain Medicine (AAPM) 2025 Annual Meeting

Research News and Market Data on TNXP

April 07, 2025 7:00am EDT Download as PDF

TNX-102 SL is a sublingual formulation of cyclobenzaprine designed for transmucosal delivery and durable activity in treating fibromyalgia

TNX-102 SL demonstrated statistically significant improvement in the primary endpoint of reduction in fibromyalgia pain in two pivotal double-blind randomized Phase 3 studies

FDA Prescription Drug User Fee Act (PDUFA) goal date of August 15, 2025, for TNX-102 SL for the management of fibromyalgia

If approved by FDA, it would become the first member of a new class of non-opioid analgesic drugs for fibromyalgia and the first new drug for treating fibromyalgia in more than 15 years

CHATHAM, N.J., April 07, 2025 (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 data in a poster presentation at the AAPM 2025 Annual Meeting, held April 3-6, 2025, in Austin, Texas. A copy of the Company’s poster, titled “Sublingual Cyclobenzaprine (TNX-102 SL) for Fibromyalgia: Efficacy and Safety in Two Randomized, Placebo-Controlled Trials” is available under the Scientific Presentations tab of the Tonix website at www.tonixpharma.com.

“Designed as a bedtime treatment to target non-restorative sleep and provide durable benefits, TNX-102 SL has shown statistically significant, robust activity in reducing fibromyalgia pain in two pivotal Phase 3 studies,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Fibromyalgia has historically been overlooked and unrecognized as a chronic pain condition. Patients’ needs have been inadequately addressed by the previously approved products, which results in many patients being prescribed chronic opioids, which are believed to be ineffective, and are instead a deleterious treatment strategy. Designed to address this nociplastic pain, TNX-102 SL now has the potential to be the first new treatment option for fibromyalgia patients in 15 years.”

In two pivotal randomized, placebo-controlled clinical trials, the efficacy of TNX-102 SL (cyclobenzaprine HCl sublingual tablets) was assessed with a primary endpoint of reducing the weekly average of daily pain from baseline after 14 weeks of treatment using the numeric rating scale scores. In both studies, TNX-102 SL significantly reduced pain and improved clinical outcomes in fibromyalgia patients while demonstrating a favorable tolerability profile via a novel mechanism of targeting the sleep disturbance associated with fibromyalgia. TNX-102 SL is a potent antagonist at four post-synaptic receptors, each of which is involved in regulating sleep. TNX-102 SL is designed for rapid, transmucosal absorption and, as demonstrated in pharmacokinetic studies, bypassing first-pass hepatic metabolism resulting in greater bioavailability of cyclobenzaprine that aligns with the sleep cycle to target non-restorative sleep for the purpose of facilitating recovery from the fibromyalgia syndrome.

About Fibromyalgia

Fibromyalgia is a common chronic pain disorder that is understood to result from amplified sensory and pain signaling within the central nervous system, called central sensitization. Brain imaging studies have localized the functional disorder to the brain’s insula and anterior cingulate cortex. Fibromyalgia afflicts more than 10 million adults in the U.S., the majority of whom are women. Symptoms of fibromyalgia include chronic widespread pain, non-restorative sleep, fatigue, and brain fog (or cognitive dysfunction). Other associated symptoms include mood disturbances, including depression, anxiety, headaches and abdominal pain or cramps. Individuals suffering from fibromyalgia often struggle with their daily activities, have impaired quality of life, and frequently are disabled. Physicians and patients report common dissatisfaction with currently marketed products. Fibromyalgia is now recognized as the prototypic nociplastic syndrome and as a chronic overlapping pain condition (COPC) Nociplastic pain is the third primary type of pain in addition to nociceptive pain and neuropathic pain. Many patients present with pain syndromes that are mixtures of the three primary types of pain. Nociplastic syndromes are associated with central and peripheral sensitization. Fibromyalgia can occur without any identifiable precipitating event. However, many fibromyalgia cases follow one or more precipitating event(s) including: post-operative pain, acute or chronic nociceptive or neuropathic pain states; recovery from an infectious illness; a cancer diagnosis or cancer treatment; a metabolic or endocrine stress; or a traumatic event. In the cases of recovery from an infectious illness, fibromyalgia is considered an Infection-Associated Chronic Condition. In addition to fibromyalgia cases associated with other conditions or stressors, the U.S. National Academies of Sciences, Engineering, and Medicine, has concluded that fibromyalgia is a diagnosable condition that can occur after recovery from COVID-19 in the context of Long COVID. Fibromyalgia is also recognized as a Chronic Overlapping Pain Condition, which is a group of related conditions that include chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME), irritable bowel syndrome, endometriosis, low back pain, post-concussive syndrome (also known as mild traumatic brain injury), chronic Lyme Disease, chronic diabetic neuropathy and chronic post-herpetic neuralgia.

About TNX-102 SL

TNX-102 SL is a centrally acting, non-opioid investigational drug, designed for chronic use. The tablet is a patented sublingual formulation of cyclobenzaprine hydrochloride (HCl) developed for bedtime dosing for the management of fibromyalgia. Cyclobenzaprine, a tertiary amine tricyclic, potently binds and acts as an antagonist at four different post-synaptic neuroreceptor subtypes: serotonergic-5-HT2A, adrenergic-α1, histaminergic-H1, and muscarinic-M1-cholinergic receptors. Together, these interactions are believed to target the non-restorative sleep characteristic of fibromyalgia identified by Professor Harvey Moldofsky in 1975. Cyclobenzaprine is not associated with risk of addiction or dependence. The TNX-102 SL tablet is based on a eutectic formulation of cyclobenzaprine HCl and mannitol that provides a stable product which dissolves rapidly and delivers cyclobenzaprine by the transmucosal route efficiently into the bloodstream. The eutectic protects cyclobenzaprine HCl from interacting with the basifying agent that is also part of the formulation and required for efficient transmucosal absorption. Patents based on TNX-102 SL’s eutectic composition and its properties have issued in the U.S., E.U., Japan, China and many other jurisdictions around the world and provide market protection into 2034. The European Patent Office’s Opposition Division maintained Tonix’s European Patent EP 2 968 992 in unamended form after an Opposition was filed against it by a Sandoz subsidiary, Hexal AG. Hexal AG did not appeal that decision. The formulation of TNX-102 SL was designed specifically for sublingual administration and transmucosal absorption for bedtime dosing to target disturbed sleep, while reducing the risk of daytime somnolence. Clinical pharmacokinetic studies indicated that relative to oral cyclobenzaprine, TNX-102 SL results in higher levels of exposure during the first 2 hours after dosing and in deceased levels of the long-lived active metabolite, norcyclobenzaprine, a secondary amine tricyclic, in both single dose and multiple dose studies, consistent with bypassing first pass hepatic metabolism. At steady state after 20 days of dosing TNX-102 SL, the dynamic peak level of cyclobenzaprine is higher than the background level of norcyclobenzaprine. In contrast, after 20 days of dosing oral cyclobenzaprine, the simulated peak level of cyclobenzaprine is lower than the simulated background level of norcyclobenzaprine.

Release – Tonix Pharmaceuticals Presented Data and Analyses of TNX-102 SL Treatment Effects on Fibromyalgia at 7th International Congress on Controversies in Fibromyalgia

Research News and Market Data on TNXP

March 04, 2025 7:00am EST Download as PDF

TNX-102 SL is a sublingual formulation of cyclobenzaprine designed for transmucosal delivery and durable activity in treating fibromyalgia

TNX-102 SL demonstrated statistically significant improvement in the primary endpoint of reduction in fibromyalgia pain in two double-blind randomized Phase 3 studies

FDA Prescription Drug User Fee Act (PDUFA) goal date of August 15, 2025, for TNX-102 SL for the management of fibromyalgia

If approved by FDA, it would become the first member of a new class of non-opioid analgesic drugs for fibromyalgia and the first new drug for treating fibromyalgia in more than 15 years

CHATHAM, N.J., March 04, 2025 (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 data in an oral presentation at the 7th International Congress on Controversies in Fibromyalgia, held March 3-4, 2025, in Vienna, Austria. A copy of the Company’s presentation, titled “Transmucosal Sublingual Cyclobenzaprine (TNX-102 SL) Treatment of Fibromyalgia at Bedtime to Target Non-Restorative Sleep Showed Durable Pain Reduction in Two Double-Blind Randomized Phase 3 Studies” is available under the Scientific Presentations tab of the Tonix website at www.tonixpharma.com following the conference.

“Since fibromyalgia is a chronic pain condition, medicines to treat fibromyalgia need to provide durable benefits,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “A randomized controlled study showed that oral, swallowed cyclobenzaprine fails to provide any durable (>1 month) benefit1. In contrast, TNX-102 SL has shown statistically significant, durable activity (3 months) in reducing fibromyalgia pain in two Phase 3 studies. The U.S. Food and Drugs Administration (FDA) has set a PDUFA goal date of August 15, 2025 for a decision on marketing authorization. TNX-102 SL now has the potential to be the first new treatment option for fibromyalgia patients in 15 years.”

Dr. Lederman continued, “TNX-102 SL is designed as a bedtime treatment to target non-restorative sleep, which in turn has shown to result in reduced pain. By providing transmucosal delivery of the tertiary amine tricyclic, TNX-102 SL results in reduced formation of the persistent active metabolite, norcyclobenzaprine (norCBP) relative to oral delivery. NorCBP accumulates after oral delivery and its potent inhibition of the norepinephrine transporter may relate to why oral cyclobenzaprine has transient (one month) activity in fibromyalgia, but not durable (three months) activity in reducing fibromyalgia pain1. Fibromyalgia, has historically been overlooked. Patients’ needs have been inadequately addressed by the three approved products, which results in many patients being prescribed chronic opioids, that are believed to be ineffective, and an actually deleterious, treatment strategy.”

TNX-102 SL (cyclobenzaprine HCl sublingual tablets) is a potent antagonist at four post-synaptic receptors, each of which is involved in regulating sleep. TNX-102 SL is designed for rapid, transmucosal absorption and, as demonstrated in pharmacokinetic studies, bypasses first-pass hepatic metabolism resulting in greater bioavailability of cyclobenzaprine that aligns with the sleep cycle to target non-restorative sleep. The sublingual formulation also results in substantially reduced creation of the active metabolite norCyclobenzaprine (norCBP) due to the bypass of first-pass hepatic metabolism. In two 14-week double-blind, randomized, placebo-controlled Phase 3 clinical trials evaluating the safety and efficacy of TNX-102 SL as a bedtime treatment for fibromyalgia, TNX-102 SL 5.6 mg met the pre-specified primary endpoints of significantly reducing daily pain compared to placebo after 14 weeks of treatment. In both trials, TNX-102 SL was generally well tolerated with an adverse event profile comparable to prior studies and with no new safety signals observed.

About Fibromyalgia
Fibromyalgia is a common chronic pain disorder that is understood to result from amplified sensory and pain signaling within the central nervous system, called central sensitization. Brain imaging studies have localized the functional disorder to the brain’s insula and anterior cingulate cortex. Fibromyalgia afflicts more than 10 million adults in the U.S., the majority of whom are women. Symptoms of fibromyalgia include chronic widespread pain, non-restorative sleep, fatigue, and brain fog (or cognitive dysfunction). Other associated symptoms include mood disturbances, including depression, anxiety, headaches and abdominal pain or cramps. Individuals suffering from fibromyalgia often struggle with their daily activities, have impaired quality of life, and frequently are disabled. Physicians and patients report common dissatisfaction with currently marketed products. Fibromyalgia is now recognized as the prototypic nociplastic syndrome and as a chronic overlapping pain condition (COPC) 2-4. Nociplastic pain is the third primary type of pain in addition to nociceptive pain and neuropathic pain. Many patients present with pain syndromes that are mixtures of the three primary types of pain. Nociplastic syndromes are associated with central and peripheral sensitization. Fibromyalgia can occur without any identifiable precipitating event. However, many fibromyalgia cases follow one or more precipitating event(s) including: post-operative pain, acute or chronic nociceptive or neuropathic pain states; recovery from an infectious illness; a cancer diagnosis or cancer treatment; a metabolic or endocrine stress; or a traumatic event. In the cases of recovery from an infectious illness, fibromyalgia is considered an Infection-Associated Chronic Condition. In addition to fibromyalgia cases associated with other conditions or stressors, the U.S. National Academies of Sciences, Engineering, and Medicine, has concluded that fibromyalgia is a diagnosable condition that can occur after recovery from COVID-19 in the context of Long COVID. Fibromyalgia is also recognized as a Chronic Overlapping Pain Condition, which is a group of related conditions that include chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME), irritable bowel syndrome, endometriosis, low back pain, post-concussive syndrome (also known as mild traumatic brain injury), chronic Lyme Disease, chronic diabetic neuropathy and chronic post-herpetic neuralgia.

About TNX-102 SL
TNX-102 SL is a centrally acting, non-opioid investigational drug, designed for chronic use. The tablet is a patented sublingual formulation of cyclobenzaprine hydrochloride developed for bedtime dosing for the management of fibromyalgia. Cyclobenzaprine potently binds and acts as an antagonist at four different post-synaptic neuroreceptor subtypes: serotonergic-5-HT2A, adrenergic-α1, histaminergic-H1, and muscarinic-M1-cholinergic receptors. Together, these interactions are believed to target the non-restorative sleep characteristic of fibromyalgia identified by Professor Harvey Moldofsky in 1975. Cyclobenzaprine is not associated with risk of addiction or dependence. The TNX-102 SL tablet is based on a eutectic formulation of cyclobenzaprine HCl and mannitol that provides a stable product which dissolves rapidly and delivers cyclobenzaprine by the transmucosal route efficiently into the bloodstream. The eutectic protects cyclobenzaprine HCl from interacting with the basifying agent that is also part of the formulation and required for efficient transmucosal absorption. Patents based on TNX-102 SL’s eutectic composition and its properties have issued in the U.S., E.U., Japan, China and many other jurisdictions around the world and provide market protection into 2034. The European Patent Office’s Opposition Division maintained Tonix’s European Patent EP 2 968 992 in unamended form after an Opposition was filed against it by a Sandoz subsidiary, Hexal AG. Hexal AG did not appeal that decision. The formulation of TNX-102 SL was designed specifically for sublingual administration and transmucosal absorption for bedtime dosing to target disturbed sleep, while reducing the risk of daytime somnolence. Clinical pharmacokinetic studies indicated that relative to oral cyclobenzaprine, TNX-102 SL results in higher levels of exposure during the first 2 hours after dosing and in deceased levels of the long-lived active metabolite, norcyclobenzaprine in both single dose and multiple dose studies, consistent with bypassing first pass hepatic metabolism. At steady state after 20 days of dosing TNX-102 SL, the dynamic peak level of cyclobenzaprine is higher than the background level of norcyclobenzaprine. In contrast, after 20 days of dosing oral cyclobenzaprine, the simulated peak level of cyclobenzaprine is lower than the simulated background level of norcyclobenzaprine.

Release – Tonix Pharmaceuticals Announces Positive Topline Results from Phase 1 Trial for TNX-1500, a Next Generation anti-CD40L mAb Candidate for Prevention of Kidney Transplant Rejection and Treatment of Autoimmune Diseases

Research News and Market Data on TNXP

February 06, 2025 8:00am EST Download as PDF

Results from the Phase 1 single ascending dose study support proceeding to develop a Phase 2 trial for the prevention of kidney transplant rejection

TNX-1500 blocked the primary and secondary antibody responses to a test antigen at the 10 mg/kg and 30 mg/kg i.v. doses

TNX-1500 showed mean half-life of 34-38 days for the 10 mg/kg and 30 mg/kg doses supporting monthly dosing for future efficacy trials

TNX-1500 was generally well-tolerated with a favorable safety profile

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

CHATHAM, N.J., Feb. 06, 2025 (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 positive topline results from its Phase 1, single ascending dose trial of TNX-1500 (Fc-modified humanized anti-CD40L monoclonal antibody, or mAb)* in healthy participants. The objectives of the Phase 1 trial were to assess the safety, tolerability, pharmacokinetics, and pharmacodynamics of intravenous TNX-1500, as well as to support dosing in a planned Phase 2 trial in kidney transplant recipients.

“There remains a significant need for new agents with improved activity and safety to prevent transplant rejection and treat autoimmune diseases,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “First generation anti-CD40L mAb therapy, particularly ruplizumab (a.k.a., humanized 5c8 or BG9588) showed activity in modulating autoimmunity and rejection in allo- and xeno-transplantation but was limited by an increased risk of thrombosis.1-3 Tonix created TNX-1500, a next generation anti-CD40L mAb, by reengineering the Fc region of ruplizumab, to preserve activity with improved safety. The results of the Phase 1 study indicate that TNX-1500 has met these design objectives. We believe the results of this study and our prior animal studies4,5 indicate that TNX-1500 is potentially best-in-class among next-generation anti-CD40L mAbs in development.”

Gregory Sullivan, M.D., Chief Medical Officer of Tonix Pharmaceuticals said, “Topline results from the TNX-1500 Phase 1 study showed TNX-1500 at the 10 mg/kg and 30 mg/kg doses blocked both the primary and secondary antibody responses to a test antigen. The pharmacokinetic data support monthly dosing at doses of 10 mg/kg or above. Based on these findings, we are eager to advance this promising candidate into a Phase 2 efficacy study. We believe TNX-1500 has the potential to prevent organ transplant rejection and improve graft survival with reduced long-term toxicity burden relative to current immunosuppressive regimens.”

Methods and Topline Results

  • Dosing: TNX-1500 solution was infused i.v. over a period of one hour to achieve doses of 3 mg/kg, 10 mg/kg, and 30 mg/kg. Participants were observed in the clinic for one day and followed with periodic clinic visits to Day 120.
  • Keyhole Limpet Hemocyanin (KLH) Challenge: To evaluate the immune modulation potency of TNX-1500, participants received an antigen challenge with KLH (Immucothel®) administered subcutaneously (SC) on Day 2 and Day 29 of the study.
  • Disposition: A total of 26 participants were enrolled in three Cohorts (3 mg/kg, 10 mg/kg, and 30 mg/kg). A total of 24 participants completed the study and two discontinued early (one placebo participant was lost to follow-up and one on TNX-1500 withdrew consent).
  • Tolerability: TNX-1500 was generally well-tolerated with a favorable safety and tolerability profile. The only treatment-emergent adverse event (TEAE) occurring in ≥ 3 participants among all TNX-1500 groups was aphthous ulcer, occurring in one participant each in the 3 mg/kg, 10 mg/kg, and 30 mg/kg groups; all were rated as mild, possibly related, and resolved in 2-10 days. There were no TEAEs assessed as related to KLH administration. No TEAEs led to study discontinuation and there were no serious adverse events. There were no thromboembolic events, which were prespecified as TEAEs of special interest.
  • Pharmacodynamics: TNX-1500 at 10 mg/kg and 30 mg/kg blocked both the primary and secondary anti-KLH Ab responses, evidenced by the mean Ab level at all sampled timepoints (through Day 120) being below the lower limit of quantitation (400 µg/L).  TNX-1500 at 3 mg/kg blocked the primary response to KLH Day 2 challenge and reduced the peak secondary response to KLH Day 29 challenge by approximately two thirds (69%) relative to the peak response to placebo.
  • Pharmacokinetics: The mean (SD) half-life of TNX-1500 was: 3 mg/kg, 19.6 (9.29) days; 10 mg/kg, 37.8 (5.46) days; and 30 mg/kg, 33.7 (4.83) days.

Tonix plans to discuss these results with the U.S. Food and Drug Administration (FDA) in an End-of-Phase 1 meeting. Pending alignment with the FDA, a Phase 2 study of TNX-1500 in kidney transplant recipients will be pursued.

About TNX-1500

TNX-1500 (Fc-modified humanized anti-CD40L mAb) is a humanized monoclonal antibody that binds and functionally inhibits 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. 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
