• Net cash used in operating activities was approximately $60.9 million, compared to $102.0 million for the prior year.
• Capital expenditures was approximately $0.1 million, compared to $29.1 million for the prior year.
• Net operating loss was approximately $126.6 million, which includes non-cash impairment charges of approximately $59.0 million, compared to net operating loss of $116.7 million for the prior year.
• The Company announced that net revenue from the sale of its marketed products was approximately $10.1 million, compared to $7.8 million for the prior year.

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 studies^4,5 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

*TNX-1500 is an investigational new biologic and is not approved for any indication

Tonix received FDA’s Day 74 Letter granting TNX-102 SL a Prescription Drug User Fee Act (PDUFA) goal date of August 15, 2025

TNX-102 SL is a non-opioid, centrally acting analgesic, granted Fast Track designation by FDA

Fibromyalgia affects more than 10 million adults in the U.S., who are mostly women

TNX-102 SL has the potential to be the first member of a new class of analgesic drugs for fibromyalgia and first new drug for its treatment in more than 15 years

NDA based on two statistically significant Phase 3 studies of TNX-102 SL for the management of fibromyalgia, in which TNX-102 SL was generally well tolerated

CHATHAM, N.J., Dec. 23, 2024 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company) today announced that the U.S. Food and Drug Administration (FDA) assigned a Prescription Drug User Fee Act (PDUFA) goal date of August 15, 2025, for a decision on marketing approval for TNX-102 SL (cyclobenzaprine HCl sublingual tablets) for fibromyalgia. TNX-102 SL is a non-opioid, centrally-acting analgesic. Fibromyalgia is a common chronic pain condition that affects mostly women.

“We look forward to working closely with the FDA throughout the review period in advance of the August 15, 2025, PDUFA goal date,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “We believe that TNX-102 SL has the potential to be the first member of a new class of medicines for the management of fibromyalgia, a debilitating condition affecting over 10 million adults in the U.S. Data from our pivotal Phase 3 trials support that TNX-102 SL can provide fibromyalgia patients with significant reduction in pain with favorable tolerability, helping to address the significant unmet need in this community.”

Dr. Lederman continued, “TNX-102 SL was previously granted Fast Track designation for fibromyalgia by the FDA in July of 2024. Fast Track is designed to expedite FDA review of important new drugs to treat serious conditions and fill an unmet medical need. This recognition from FDA confirms that the Agency recognizes the significant unmet needs of the fibromyalgia community, who have been waiting for a new drug for over 15 years.”

The accepted NDA is supported by data from 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. The first Phase 3 trial, RELIEF, of TNX-102 SL 5.6 mg in fibromyalgia, completed in December 2020, met its pre-specified primary endpoint of significantly reducing daily pain compared to placebo (p=0.010). In the confirmatory Phase 3 RESILIENT study in fibromyalgia, completed in December 2023, TNX-102 SL again met the pre-specified primary endpoint of significantly reducing daily pain compared to placebo (p =0.00005). 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. In both pivotal studies, the most common treatment-emergent adverse event was tongue or mouth numbness at the administration site, which was temporally related to dosing, self-limited, never rated as severe, and rarely led to study discontinuation (one participant in each study). Excluding COVID-19, rates of systemic adverse events in each of the two studies were all below 4.0%. Tonix believes the submitted dossier contains the requisite safety and efficacy data from two adequate and well-controlled studies to support NDA approval.

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. 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-HT_2A, 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.

September 16, 2024 7:00am EDT

The World Health Organization (WHO) released its preferred target product profile (TPP) criteria for mpox vaccines at its Mpox Research and Innovation Scientific Conference held August 29-30

TNX-801, Tonix’s attenuated live-virus vaccine candidate, has characteristics that align closely with WHO’s TPP

On August 14, 2024, the WHO determined that the upsurge of mpox in a growing number of countries in Africa constitutes a public health emergency of international concern^1–4: cases of the potentially lethal new Clade I mpox also detected in Sweden, Thailand and Singapore

CHATHAM, N.J., Sept. 16, 2024 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a fully-integrated biopharmaceutical company with marketed products and a pipeline of development candidates, announced today that the World Health Organization’s (WHO’s) preferred target product profile (TPP), released at the WHO sponsored Mpox Research and Innovation Scientific Conference held August 29-30, 2024, aligns with the characteristics of TNX-801 (horsepox, live virus) vaccine, which is being developed for preventing mpox (formerly known as monkeypox). 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.

“The characteristics of TNX-801 align with the draft TPP released at the WHO sponsored Mpox Research and Innovation Scientific Conference,” said Seth Lederman, M.D., Chief Executive Officer of Tonix. “In animal studies TNX-801 has shown single dose protection against a lethal challenge of Clade I monkeypox virus administered by intratracheal route.⁵ In addition, protected animals did not produce any infectious virus suggesting TNX-801 has the potential to block forward transmission as expected with live-virus vaccines. TNX-801 is designed for percutaneous administration using a bifurcated needle, like the products and delivery used in WHO’s accelerated smallpox eradication project. Since TNX-801 is a live-virus vaccine, we expect the stability of lyophilized TNX-801 at ambient temperature to be similar to live vaccinia virus vaccines including ACAM2000. We believe TNX-801 can be shipped and stored without the need for a costly and cumbersome ultra-cold supply chain, a particular advantage in lesser developed parts of the world. The stability of live virus vaccines eliminates the need for ultra-cold storage which complicates the widespread use of mRNA vaccines in Africa, where they are needed most right now. Finally, studies on immunocompromised animals⁶ suggest that TNX-801 may be given to persons with immunocompromising conditions such as HIV, which is another property that will be essential for public health.”

Dr. Lederman continued, “The recent WHO declaration of a Public Health Emergency of International Concern (PHEIC) underscores the urgent need for new vaccines to control this outbreak and save lives. We have been motivated to develop TNX-801 because single-dose vaccines simplify logistics of administration, achieve higher coverage by reducing vaccinee dropout between doses and allow for case-contact or “ring” strategies to vaccinate the contacts of confirmed mpox patients.^7,8 Ring vaccination is deemed essential for controlling mpox but requires single-dose vaccines that interrupt forward transmission.”^7,8

On August 26, 2024, Tonix announced a collaboration with Bilthoven Biologics (Bbio) to develop GMP manufacturing processes for its mpox vaccine. Bbio is part of the world’s largest vaccine manufacturer, the Cyrus Poonawalla Group, which also includes the Serum Institute of India.

The U.S. Food and Drug Administration (FDA) approved vaccines for mpox are a two-dose non-replicating vaccine called Jynneos® from Bavarian Nordic⁹ and a one-dose live-virus vaccine from Emergent for people at high risk for mpox infection.¹⁰ WHO recently authorized Jynneos for use in adults.¹¹ Recently data in animals have been reported for a two-dose mRNA vaccine from Moderna.¹²

About TNX-801^*

TNX-801 is a live replicating attenuated vaccine based on horsepox that is believed to provide immune protection with better tolerability than 20^th Century vaccinia viruses. As previously disclosed, TNX-801 protected animals against lethal challenge with intratracheal Clade I monkeypox virus.⁵ After a single dose vaccination, TNX-801 prevented clinical disease and lesions and also decreased shedding in the mouth and lungs of non-human primates.⁶ The Findings are consistent with mucosal immunity and suggest the ability to block forward transmission, similar to Dr. Edward Jenner’s vaccinia vaccine, which eradicated smallpox and kept mpox out of the human population. TNX-801 combines immune protection with improved tolerability compared to other vaccines based on orthopoxviruses and is administered with a single dose which has advantages over two-dose regimens. The focus on single-dose vaccines confirms early recommendations by the Bipartisan Commission on Biodefense, ⁷ and the U.S. National Academies of Science.^7,8 The National Academies of Science (NAS) report highlights the difficulty of a ring vaccination strategy with even a two-dose regimen. ⁷ The U.S. National Institutes of Health (NIH) selected Tonix’s COVID-19 vaccine, TNX-1800 for Project NextGen. TNX-1800 is an engineered version of horsepox that expresses the spike protein of SARS-CoV-2. ^13,14

About Mpox^*
On August 14, 2024, the WHO determined that the upsurge of mpox in a growing number of countries in Africa constitutes a PHEIC the second such declaration in the past two years called in response to an mpox outbreak.¹ The current outbreak is caused by Clade I monkeypox virus, while the 2022 outbreak was Clade 2 monkeypox virus. The global mpox outbreak, which commenced in 2022 has affected over 90,000 persons in countries where mpox had previously not been endemic, including Europe and the US. The spread of Clade IIb strain mpox in 2022 underscores the pandemic potential of mpox. Unlike Clade IIb mpox, the Clade I strain of mpox appears to be spreading to countries neighboring the Democratic Republic of the Congo, including Burundi, Rwanda, Uganda and Kenya. Clade I mpox is typically associated with approximately twenty times the case fatality rates than Clade IIb mpox in Africa. According to the U.S. Centers for Disease Control and Prevention (CDC), and other experts, there is a significant risk that the deadlier Clade I strain may appear in the U.S.^2,3
