Tonix Announced Acquisition of A Non-Opioid Pain Reliever. Tonix continues to build its neurological pain pipeline with the licensing of a Sigma-1 receptor antagonist for development in neuropathic pain relief. Published studies on the Sigma-1 receptor’s mechanism of action have shown activity in pain and several neurological diseases. We see this as an extension of the company’s product line in neurology, including products for fibromyalgia/pain, acute stress disorder, major depressive disorder, and migraine headache.
TNX-4900 Is Highly Selective For The Sigma-1 Receptor. The new molecule, known as TNX-4900, is a small molecule developed to be highly selective for the Sigma-1 receptor, avoiding the Sigma-2 and other Sigma receptor-family members. It has been tested in multiple models of pain and selected for its efficacy and safety profile. TNX-4900 has also shown ability to cross the blood-brain barrier, with favorable adsorption, distribution, metabolism and elimination (ADME) properties.

NX-801 is a live virus vaccine investigational candidate, designed to provide durable protection against mpox and smallpox
TNX-801 demonstrated favorable safety, immunogenicity, and long-term protection in multiple preclinical models
Data support advancement of TNX-801 toward clinical development
CHATHAM, N.J., Oct. 17, 2025 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (“Tonix” or the “Company”) presented data in an oral presentation at the World Vaccine Congress–Europe 2025, held October 14–16, 2025, in Amsterdam, the Netherlands. A copy of the Company’s presentation, titled “Safety, Durability and Protection of a Single-Dose TNX-801 Mpox Vaccine,” is available under the Scientific Presentations tab of the Tonix website at www.tonixpharma.com.
“Vaccines remain a cornerstone of pandemic preparedness and biodefense,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “The data presented in Amsterdam support the potential of TNX-801 as a next-generation orthopoxvirus vaccine candidate with the ability to confer durable protection. We believe TNX-801 has the potential to strengthen global readiness for emerging and re-emerging poxvirus threats.”
TNX-801 is a live, attenuated, minimally replicative investigational vaccine candidate based on horsepox virus and is being developed to protect against mpox (monkeypox) and smallpox. Preclinical data presented by Sina Bavari, Ph.D., Executive Vice President, Infectious Disease Research at Tonix Pharmaceuticals, demonstrated that TNX-801 produced durable immune protection following a single dose and was well tolerated across multiple routes of administration, including percutaneous, subcutaneous, and intramuscular delivery. TNX-801 elicited strong neutralizing antibody responses and protected animals from clinical disease and mortality following mpox challenge in non-human primate, rabbit, and murine models. Immunogenicity and durability were observed for at least 14 months post-vaccination.
“We are encouraged by the consistency and durability of the TNX-801 data across multiple preclinical models,” said Dr. Sina Bavari. “We are also excited by the opportunity to evaluate microneedle patch technology as a novel delivery platform to simplify administration and expand vaccine accessibility in future development stages.”
About TNX-801* TNX-801 (recombinant horsepox virus) is an, 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. Smallpox vaccines descended from Jenner’s vaccine used prior to 1900 would be called horsepox by modern nomenclature.. 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.

INDICATION TONMYA is indicated for the treatment of fibromyalgia in adults. CONTRAINDICATIONS TONMYA is contraindicated: In patients with hypersensitivity to cyclobenzaprine or any inactive ingredient in TONMYA. Hypersensitivity reactions may manifest as an anaphylactic reaction, urticaria, facial and/or tongue swelling, or pruritus. Discontinue TONMYA if a hypersensitivity reaction is suspected. With concomitant use of monoamine oxidase (MAO) inhibitors or within 14 days after discontinuation of an MAO inhibitor. Hyperpyretic crisis seizures and deaths have occurred in patients who received cyclobenzaprine (or structurally similar tricyclic antidepressants) concomitantly with MAO inhibitors drugs. During the acute recovery phase of myocardial infarction, and in patients with arrhythmias, heart block or conduction disturbances, or congestive heart failure. In patients with hyperthyroidism. WARNINGS AND PRECAUTIONS Embryofetal toxicity: Based on animal data, TONMYA may cause neural tube defects when used two weeks prior to conception and during the first trimester of pregnancy. Advise females of reproductive potential of the potential risk and to use effective contraception during treatment and for two weeks after the final dose. Perform a pregnancy test prior to initiation of treatment with TONMYA to exclude use of TONMYA during the first trimester of pregnancy. Serotonin syndrome: Concomitant use of TONMYA with selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants, tramadol, bupropion, meperidine, verapamil, or MAO inhibitors increases the risk of serotonin syndrome, a potentially life-threatening condition. Serotonin syndrome symptoms may include mental status changes, autonomic instability, neuromuscular abnormalities, and/or gastrointestinal symptoms. Treatment with TONMYA and any concomitant serotonergic agent should be discontinued immediately if serotonin syndrome symptoms occur and supportive symptomatic treatment should be initiated. If concomitant treatment with TONMYA and other serotonergic drugs is clinically warranted, careful observation is advised, particularly during treatment initiation or dosage increases. Tricyclic antidepressant-like adverse reactions: Cyclobenzaprine is structurally related to TCAs. TCAs have been reported to produce arrhythmias, sinus tachycardia, prolongation of the conduction time leading to myocardial infarction and stroke. If clinically significant central nervous system (CNS) symptoms develop, consider discontinuation of TONMYA. Caution should be used when TCAs are given to patients with a history of seizure disorder, because TCAs may lower the seizure threshold. Patients with a history of seizures should be monitored during TCA use to identify recurrence of seizures or an increase in the frequency of seizures. Atropine-like effects: Use with caution in patients with a history of urinary retention, angle-closure glaucoma, increased intraocular pressure, and in patients taking anticholinergic drugs. CNS depression and risk of operating a motor vehicle or hazardous machinery: TONMYA monotherapy may cause CNS depression. Concomitant use of TONMYA with alcohol, barbiturates, or other CNS depressants may increase the risk of CNS depression. Advise patients not to operate a motor vehicle or dangerous machinery until they are reasonably certain that TONMYA therapy will not adversely affect their ability to engage in such activities. Oral mucosal adverse reactions: In clinical studies with TONMYA, oral mucosal adverse reactions occurred more frequently in patients treated with TONMYA compared to placebo. Advise patients to moisten the mouth with sips of water before administration of TONMYA to reduce the risk of oral sensory changes (hypoesthesia). Consider discontinuation of TONMYA if severe reactions occur. ADVERSE REACTIONS The most common adverse reactions (incidence ≥2% and at a higher incidence in TONMYA-treated patients compared to placebo-treated patients) were oral hypoesthesia, oral discomfort, abnormal product taste, somnolence, oral paresthesia, oral pain, fatigue, dry mouth, and aphthous ulcer.
DRUG INTERACTIONS
MAO inhibitors: Life-threatening interactions may occur. Other serotonergic drugs: Serotonin syndrome has been reported. CNS depressants: CNS depressant effects of alcohol, barbiturates, and other CNS depressants may be enhanced. Tramadol: Seizure risk may be enhanced. Guanethidine or other similar acting drugs: The antihypertensive action of these drugs may be blocked. USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data, TONMYA may cause fetal harm when administered to a pregnant woman. The limited amount of available observational data on oral cyclobenzaprine use in pregnancy is of insufficient quality to inform a TONMYA-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Advise pregnant women about the potential risk to the fetus with maternal exposure to TONMYA and to avoid use of TONMYA two weeks prior to conception and through the first trimester of pregnancy. Report pregnancies to the Tonix Medicines, Inc., adverse-event reporting line at 1-888-869-7633 (1-888-TNXPMED). Lactation: A small number of published cases report the transfer of cyclobenzaprine into human milk in low amounts, but these data cannot be confirmed. There are no data on the effects of cyclobenzaprine on a breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for TONMYA and any potential adverse effects on the breastfed child from TONMYA or from the underlying maternal condition. Pediatric use: The safety and effectiveness of TONMYA have not been established. Geriatric patients: Of the total number of TONMYA-treated patients in the clinical trials in adult patients with fibromyalgia, none were 65 years of age and older. Clinical trials of TONMYA did not include sufficient numbers of patients 65 years of age and older to determine whether they respond differently from younger adult patients. Hepatic impairment: The recommended dosage of TONMYA in patients with mild hepatic impairment (HI) (Child Pugh A) is 2.8 mg once daily at bedtime, lower than the recommended dosage in patients with normal hepatic function. The use of TONMYA is not recommended in patients with moderate HI (Child Pugh B) or severe HI (Child Pugh C). Cyclobenzaprine exposure (AUC) was increased in patients with mild HI and moderate HI compared to subjects with normal hepatic function, which may increase the risk of TONMYA-associated adverse reactions. Please see additional safety information in the full Prescribing Information. To report suspected adverse reactions, contact Tonix Medicines, Inc. at 1-888-869-7633, or the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
CHATHAM, N.J., Oct. 14, 2025 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (“Tonix” or the “Company”), a fully integrated biotechnology company with marketed products and a pipeline of development candidates, today announced that Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals, delivered a presentation titled “The History and Promise of anti-CD154 Monoclonal Antibody Immunomodulation for Transplantation,” at the 61st Annual Congress of the Japan Society for Transplantation, which took place October 9–11, 2025, in Nagoya, Japan. The CD40-ligand (CD40L) is also known as CD154. A copy of the Company’s presentation is available under the Presentations tab of the Tonix website at https://ir.tonixpharma.com/presentations.
“We are encouraged by the favorable safety and biomarker data from the Phase 1 study, which support the continued development of TNX-1500 as a novel immunomodulatory approach in transplantation and autoimmune diseases,” said Dr. Seth Lederman, Chief Executive Officer of Tonix Pharmaceuticals. “Dimeric TNX-1500 was designed to target cell-associated CD40L, which we believe plays important roles in organ rejection. We look forward to engaging further with the transplantation and immunology communities as we move into next-stage studies.”
Dr. Lederman added, “Several studies have shown that anti-CD40L treatment of animals with transplanted organs is associated with an increase in the number and activity of T-regulatory cells (“T regs”). We are excited that Mary Brunkow, Fred Ramsdell and Shimon Sakaguchi were awarded the Nobel Prize in Physiology or Medicine 2025 for the discovery and characterization of these T regs and their role in peripheral immune tolerance just a few days before the conference. The growing recognition of the significance of T regs in the immune response has driven our interest in pursuing anti-CD40L treatment to prevent organ transplant rejection.”
Dr. Lederman’s presentation highlighted his discovery of CD40L as a therapeutic target, the evolution of anti-CD40L therapeutic monoclonal antibodies and featured data from the completed Phase 1 study of TNX-1500, Tonix’s third-generation Fc-modified dimeric anti-CD40L monoclonal antibody. The talk reviewed the molecule’s design to minimize thromboembolic risk while maintaining immunomodulatory activity, presented Phase 1 safety and pharmacodynamic results, and outlined next steps toward Phase 2 development for the prevention of kidney transplant rejection and the treatment of autoimmune indications.
Dr. Lederman’s presentation was part of a morning breakfast seminar sponsored by Tonix and chaired by Professor Takaaki Kobayashi, from Aichi Medical University School of Medicine, that included presentations by two academic Tonix collaborators: a presentation by Harvard Professor and Massachusetts General Hospital (MGH) surgeon Richard Pierson III titled, “CD154/CD40 blockade with Fc-modified anti-CD154 mAb for heart transplantation” and a presentation by Harvard Professor and MGH surgeon Tatsuo Kawai titled, “CD154/CD40 blockade with Fc-modified anti-CD154 for kidney transplantation.”
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.

CHATHAM, N.J., Sept. 18, 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 successful completion of a Type B Pre-Investigational New Drug (Pre-IND) meeting with the U.S. Food and Drug Administration (FDA) regarding the development of TNX-102 SL (sublingual cyclobenzaprine HCl) for the treatment of major depressive disorder (MDD). The Company received positive feedback from the FDA and plans to pursue a supplemental new drug application (sNDA) to expand the therapeutic indication of TNX-102 SL to include MDD, based on exploratory findings suggesting that improving sleep quality may positively impact depressive symptoms.
“We are pleased with the outcome of our Pre-IND meeting with the FDA and appreciate their thoughtful guidance,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “This marks a significant step forward in our efforts to develop TNX-102 SL as a novel treatment for MDD, a condition that affects millions and remains underserved by current therapies that are often difficult to tolerate.”
“We believe bedtime TNX-102 SL has the potential to be a first-in-class treatment that is designed to target the reduced quality and quantity of slow wave sleep associated with depression,” said Dr. Gregory Sullivan, M.D., Chief Medical Officer of Tonix Pharmaceuticals. “TNX-102 SL is a tertiary amine tricyclic that is designed for transmucosal absorption to bypass first pass hepatic metabolism. In contrast, FDA-approved tertiary amine tricyclic antidepressants are swallowed pill formulations, that are largely metabolized by first-pass to longer-lived secondary amine tricyclics. Also, the FDA-approved tertiary amine tricyclic antidepressants are only active in treating MDD at more than ten times the dose employed with TNX-102 SL and can adversely impact weight, blood pressure, cognition, and sexual function.”
The FDA provided constructive feedback during the Pre-IND meeting for TNX-102 SL in MDD and found the proposed long-term safety data collection plan generally reasonable, potentially streamlining the development path.
An IND filing is planned for Q4 2025, positioning the program to enter Phase 2 clinical trials shortly thereafter. TNX-102 SL is FDA approved for the treatment of fibromyalgia, under the brand name Tonmya™. In the Phase 3 RESILIENT study of fibromyalgia patients, the TNX-102 SL – treated group had activity on improving depression over placebo by the Beck Depression Inventory (BDI), with an uncorrected p-value < 0.05. The biological relationship between depressed symptoms in fibromyalgia and those in MDD is not understood.
About TNX-102 SL TNX-102 SL is a patented sublingual tablet formulation of cyclobenzaprine hydrochloride that enables rapid transmucosal absorption and reduces production of the long half-life active metabolite, norcyclobenzaprine, by bypassing first-pass hepatic metabolism. As a tertiary amine tricyclic (TAT) and multifunctional agent with potent binding and antagonist activities at the 5-HT2A serotonergic, α1-adrenergic, H1-histaminergic, and M1-muscarinic receptors. It is currently approved in the U.S. as a once-daily bedtime treatment for fibromyalgia in adults. TNX-102 SL is also in development as a daily bedtime treatment for acute stress reaction/acute stress disorder. Tonix also holds active IND’s for the following indications for TNX-102 SL: Long COVID (post-acute sequelae of COVID-19), PTSD, alcohol use disorder, and agitation in Alzheimer’s disease. The United States Patent and Trademark Office (USPTO) issued United States Patent No. 9636408 in May 2017, Patent No. 9956188 in May 2018, Patent No. 10117936 in November 2018, Patent No. 10357465 in July 2019, and Patent No. 10736859 in August 2020. The Protectic™ protective eutectic and Angstro-Technology™ formulation claimed in the patent are important elements of Tonix’s proprietary composition. These patents are expected to provide Tonmya with U.S. market exclusivity until 2034. Pending patent applications related to method of use could extend exclusivity until 2044.

INDICATION TONMYA is indicated for the treatment of fibromyalgia in adults.
CONTRAINDICATIONS TONMYA is contraindicated: In patients with hypersensitivity to cyclobenzaprine or any inactive ingredient in TONMYA. Hypersensitivity reactions may manifest as an anaphylactic reaction, urticaria, facial and/or tongue swelling, or pruritus. Discontinue TONMYA if a hypersensitivity reaction is suspected.
With concomitant use of monoamine oxidase (MAO) inhibitors or within 14 days after discontinuation of an MAO inhibitor. Hyperpyretic crisis seizures and deaths have occurred in patients who received cyclobenzaprine (or structurally similar tricyclic antidepressants) concomitantly with MAO inhibitors drugs. During the acute recovery phase of myocardial infarction, and in patients with arrhythmias, heart block or conduction disturbances, or congestive heart failure. In patients with hyperthyroidism.
WARNINGS AND PRECAUTIONS Embryofetal toxicity: Based on animal data, TONMYA may cause neural tube defects when used two weeks prior to conception and during the first trimester of pregnancy. Advise females of reproductive potential of the potential risk and to use effective contraception during treatment and for two weeks after the final dose. Perform a pregnancy test prior to initiation of treatment with TONMYA to exclude use of TONMYA during the first trimester of pregnancy.
Serotonin syndrome: Concomitant use of TONMYA with selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants, tramadol, bupropion, meperidine, verapamil, or MAO inhibitors increases the risk of serotonin syndrome, a potentially life-threatening condition. Serotonin syndrome symptoms may include mental status changes, autonomic instability, neuromuscular abnormalities, and/or gastrointestinal symptoms. Treatment with TONMYA and any concomitant serotonergic agent should be discontinued immediately if serotonin syndrome symptoms occur and supportive symptomatic treatment should be initiated. If concomitant treatment with TONMYA and other serotonergic drugs is clinically warranted, careful observation is advised, particularly during treatment initiation or dosage increases.
Tricyclic antidepressant-like adverse reactions: Cyclobenzaprine is structurally related to TCAs. TCAs have been reported to produce arrhythmias, sinus tachycardia, prolongation of the conduction time leading to myocardial infarction and stroke. If clinically significant central nervous system (CNS) symptoms develop, consider discontinuation of TONMYA. Caution should be used when TCAs are given to patients with a history of seizure disorder, because TCAs may lower the seizure threshold. Patients with a history of seizures should be monitored during TCA use to identify recurrence of seizures or an increase in the frequency of seizures. Atropine-like effects: Use with caution in patients with a history of urinary retention, angle-closure glaucoma, increased intraocular pressure, and in patients taking anticholinergic drugs.
CNS depression and risk of operating a motor vehicle or hazardous machinery: TONMYA monotherapy may cause CNS depression. Concomitant use of TONMYA with alcohol, barbiturates, or other CNS depressants may increase the risk of CNS depression. Advise patients not to operate a motor vehicle or dangerous machinery until they are reasonably certain that TONMYA therapy will not adversely affect their ability to engage in such activities.
Oral mucosal adverse reactions: In clinical studies with TONMYA, oral mucosal adverse reactions occurred more frequently in patients treated with TONMYA compared to placebo. Advise patients to moisten the mouth with sips of water before administration of TONMYA to reduce the risk of oral sensory changes (hypoesthesia). Consider discontinuation of TONMYA if severe reactions occur.
ADVERSE REACTIONS The most common adverse reactions (incidence ≥2% and at a higher incidence in TONMYA-treated patients compared to placebo-treated patients) were oral hypoesthesia, oral discomfort, abnormal product taste, somnolence, oral paresthesia, oral pain, fatigue, dry mouth, and aphthous ulcer.
DRUG INTERACTIONS MAO inhibitors: Life-threatening interactions may occur.
Other serotonergic drugs: Serotonin syndrome has been reported.
CNS depressants: CNS depressant effects of alcohol, barbiturates, and other CNS depressants may be enhanced.
Tramadol: Seizure risk may be enhanced.
Guanethidine or other similar acting drugs: The antihypertensive action of these drugs may be blocked.
USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data, TONMYA may cause fetal harm when administered to a pregnant woman. The limited amount of available observational data on oral cyclobenzaprine use in pregnancy is of insufficient quality to inform a TONMYA-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Advise pregnant women about the potential risk to the fetus with maternal exposure to TONMYA and to avoid use of TONMYA two weeks prior to conception and through the first trimester of pregnancy. Report pregnancies to the Tonix Medicines, Inc., adverse-event reporting line at 1-888-869-7633 (1-888-TNXPMED).
Lactation: A small number of published cases report the transfer of cyclobenzaprine into human milk in low amounts, but these data cannot be confirmed. There are no data on the effects of cyclobenzaprine on a breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for TONMYA and any potential adverse effects on the breastfed child from TONMYA or from the underlying maternal condition.
Pediatric use: The safety and effectiveness of TONMYA have not been established. Geriatric patients: Of the total number of TONMYA-treated patients in the clinical trials in adult patients with fibromyalgia, none were 65 years of age and older. Clinical trials of TONMYA did not include sufficient numbers of patients 65 years of age and older to determine whether they respond differently from younger adult patients.
Hepatic impairment: The recommended dosage of TONMYA in patients with mild hepatic impairment (HI) (Child Pugh A) is 2.8 mg once daily at bedtime, lower than the recommended dosage in patients with normal hepatic function. The use of TONMYA is not recommended in patients with moderate HI (Child Pugh B) or severe HI (Child Pugh C). Cyclobenzaprine exposure (AUC) was increased in patients with mild HI and moderate HI compared to subjects with normal hepatic function, which may increase the risk of TONMYA-associated adverse reactions.
Please see additional safety information in the full Prescribing Information.
To report suspected adverse reactions, contact Tonix Medicines, Inc. at 1-888-869-7633, or the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

Management Discussed Plans For Marketing and Launch. Following the FDA approval of Tonmya (or TNXP-102 SL) on August 15, Tonix held a webcast to discuss plans for marketing and sales in advance of its 4Q25 launch. The presentations included a discussion of fibromyalgia, the market, and the Tonmya product label. We believe the clinical data shows meaningful improvements for several important symptoms.
Fibromyalgia Market Is Large and Underestimated. The fibromyalgia population is estimated at about 10 million diagnosed patients. Patients live with symptoms for an average of 7 years before diagnosis, including bodily pain (the most common). Other symptoms include fatigue, insomnia, anxiety, “brain fog”. and depression. Many patients are on multiple drugs, taking an average of 2.7 drugs at any given time. As a non-opioid, non-habit forming drug, we believe Tonmya can meet the need for an effective therapy.

We Are On The Edge Of Our Seats Waiting For TNX-102 SL. Tonix reported a 2Q25 loss of $28.3 million or $(3.86) per share. Importantly, the PDUFA date for TNX-102 SL is August 15. This is the date when the FDA is required to answer the application for approval. We continue to expect TNX-102 SL to be approved this week. Cash on hand at the end of the quarter was $125.3 million.
TNX-102 SL Launch Is Planned For 4Q25. The company expects to have TNX-102 SL available during 4Q25, as we expected. It will be the first drug developed and approved for fibromyalgia, compared with the current therapies that were approved for other conditions then expanded into fibromyalgia. Importantly, TNX-102 SL met its primary endpoint of pain relief and all six secondary endpoints for relief of symptoms.

TNX-801 is up to 100,000-fold less virulent than live smallpox vaccine strains and a single dose provides robust immunogenicity and protection against mpox and rabbitpox (more than one year) in animals
Subcutaneous administration of TNX-801 yielded equivalent protection to the traditional percutaneous administration
CHATHAM, N.J., July 10, 2025 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP), a fully integrated biopharmaceutical company with marketed products and a pipeline of development candidates, today announced the presentation of new findings on TNX-801 (recombinant horsepox, live virus vaccine) at the Vaccine Congress 2025 in Vienna on July 10, 2025, by Sina Bavari, PhD, Executive Vice President, Infectious Disease Research and Development.
“The data show that TNX-801 can deliver durable immunity while remaining highly attenuated, a balance that sets it apart from earlier orthopox vaccines,” said Seth Lederman, MD, Chief Executive Officer of Tonix Pharmaceuticals. “The novel finding that subcutaneous (s.c.) administration of TNX-801 provides equivalent protection to percutaneous administration, is leading us to develop the s.c. product first. Most live-virus vaccines are delivered s.c. and this route of administration has further potential benefits of decreased administration-site bacterial superinfection, scarring, or inadvertent transfer to other body sites by itching. We believe TNX-801 has the potential to become a critical tool for containing mpox and preparedness against the malicious reintroduction of smallpox. We look forward to advancing TNX-801 into the clinic by s.c. delivery.”
TNX-801 is a recombinant horsepox-derived vaccine candidate designed to prevent orthopox viruses and provide durable humoral and cellular immunity from a single dose. In primary human dermal cells, the virus replicates twenty-seven to one-hundred-nineteen-fold less than licensed vaccinia strains, and in interferon receptor knockout mice it is up to one-hundred-thousand-fold less virulent than those legacy vaccines. Preclinical studies further showed that a single dose of TNX-801 produced strong binding and neutralizing antibody responses across mice, rabbits, hamsters, and cynomolgus macaques, including immunocompromised animals. All vaccinated macaques survived lethal Clade I mpox challenge without lesions, and rabbit models remained fully protected for fourteen months.
“Our data show that TNX-801 delivers durable immunity without safety concerns of live virus vaccines,” said Dr Bavari. “TNX-801 dissociates immune protection from some of the side-effects associated with traditional vaccinia-based vaccines and potentially offers a unique risk-benefit profile for mpox and smallpox prevention. We are excited to advance this program toward clinical evaluation in collaboration with public-health partners worldwide.”
The World Health Organization and the Centers for Disease Control and Prevention continue to classify mpox as an ongoing public-health concern. A single-dose vaccine with the attenuation and immunogenicity profile demonstrated by TNX-801 could streamline outbreak response by reducing the need for approved multi-visit immunization schedules.

1Q25 Reported With Product Updates. Tonix reported a 1Q25 loss of $16.8 million or $(2.84) per share, a smaller loss than we had estimated. Product sales were $2.4 million, slightly lower than the $2.6 million in 4Q24. Gross margins were 61%, an improvement over the 54% seen in 4Q24. TNX-102 SL has a PDUFA date of August 15, and preparations continue for launch in 4Q25. Cash on hand on March 31 was $131.7 million.
Anticipation Builds For TNX-102 SL PDUFA Date. We believe the two Phase 3 trials support product approval for TNX-102 SL in its fibromyalgia indication. As we have described in previous Research Notes, fibromyalgia is currently treated with a combination of pain relievers (opioid and neurological), antidepressants, and insomnia drugs. TNX-102 SL could become the first drug to relieve all major symptoms without side effects from each class of drug.

Combination treatment of TFF2 with anti-PD1 antibody was associated with the activation of cancer-killing CD8+ T Cells and limiting immune evasion by tumor cells
TNX-1700 is in preclinical development for gastric and colorectal cancers
CHATHAM, N.J., April 29, 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 American Association for Cancer Research (AACR) 2025 Annual Meeting, held April 25-30, 2025, in Chicago, IL. A copy of the Company’s presentation is available under the Scientific Presentations tab of the Tonix website at www.tonixpharma.com. The presentation titled, “TFF2-mediated CXCR4 partial agonism outperforms CXCR4 antagonism in reducing murine gastric cancer by suppressing PMN-MDSC generation,” demonstrated positive data in gastric cancer animal models. In the AACR presentation, a fusion protein of murine trefoil factor family member 2- murine serum albumin (mTFF2-MSA) was studied. Tonix is developing human TFF2-human serum albumin (hTFF2-HAS) as TNX-1700.
“The combination therapy of mTFF2-MSA with anti-PD1 treatment shows promise in reducing immunosuppression in the tumor microenvironment (TME) in animal models,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “We are excited to develop TNX-1700 (TFF2-HAS) as the lead program in our immuno-oncology pipeline, by testing potential dosing strategies, and establishing potential clinical biomarkers through preclinical models.”
Immunosuppressive neutrophils, also known as polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs), are a major component in solid tumors that significantly hinder anti-tumor activity1,2. Despite being short-lived, their continuous replenishment from the bone marrow sustains their potent immunosuppression in the TME3. 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 CXCR44,5. Data presented in the poster demonstrated 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. TFF2 reduction correlated with elevated PMN-MDSCs in gastric cancer patients, highlighting the potential negative correlation between TFF2 and PMN-MDSCs levels.
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 (rTFF2-HSA) for the treatment of gastric and colon 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 rTFF2 in combination with other therapies in cancer prevention and early treatment.

We see this as a sign that the NDA review has not raised questions about the clinical trial data, potential patient use, or other factors that would be answered by an Advisory Committee. Since the trial met its primary endpoint and all six secondary endpoints with high statistical significance, we interpret this to be a positive sign.
FDA Advisory Panel Hearings Evaluate and Provide Insight To Trial Data. As part of its NDA review process, the FDA may schedule an Advisory Committee hearing. The committee members each bring expertise in aspects of clinical practice, research, or statistical analysis. At a hearing, the company presents its analysis of the trial and the data, followed by the FDA’s analysis. The Committee members then ask questions to make recommendations for or against NDA approval and/or product labeling. We see the review without an Advisory Committee as a sign that the FDA does not need additional information on efficacy or safety.

The World Health Organization (WHO) recently reaffirmed the spread of new clade Ib Mpox a public health emergency of international concern (PHEIC): second Mpox-related WHO PHEIC declaration in two years

Tolerability of TNX‐801 vaccination in immune-compromised animal models supports clinical development
CHATHAM, N.J., March 10, 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 it has been awarded a grant from the Medical CBRN Defense Consortium (MCDC) to support the development of TNX-801 (recombinant horsepox virus, live vaccine). MCDC is a consortium of industrial, academic, and non-profit entities that supports the U.S. government in meeting military requirements for medical products to protect against chemical, biological, radiological and nuclear (CBRN) threats. TNX-801 is in development as an mpox and smallpox vaccine with the potential to be delivered via innovative alternative methods to improve patient compliance, ease of use and tolerability. The MCDC grant will allow for further comprehensive market analyses, target market identification and commercialization planning, including for both private and government markets.
“We are excited by the opportunity to collaborate with MCDC and are thankful for their support of our vaccine candidate,” said Seth Lederman, M.D., President, and Chief Executive Officer of Tonix. “TNX-801 offers an appealing target product profile, requiring just a single dose for durable, long-term protection, with favorable shipping and storage requirements. With a significant global unmet need, TNX-801 is in a strong position to make a potential impact towards preventing mpox and controlling mpox epidemics.”
TNX-801 is an attenuated 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. TNX-801 has previously been shown to protect animals against lethal challenge with intratracheal clade I monkeypox virus.1 An outbreak of clade I mpox was declared a Public Health Emergency of International Concern (PHEIC) by the World Health Organization (WHO) in August of 2024 and reaffirmed in February 2025.2,3 Starting from an outbreak in the Democratic Republic of the Congo, clade I mpox has spread to sixteen Central African Countries and outside of Africa, including in China, Thailand, Singapore, India, England, parts of Europe and the Middle East, Canada and the United States.4
