$3 million awarded by DoD to University of North Carolina Institute of Trauma Recovery to support a proposed 180-patient, randomized, placebo-controlled trial in acute trauma patients

Investigator sponsored trial to evaluate the potential for TNX-102 SL¹ to reduce the frequency and severity of acute stress reaction, acute stress disorder, and post-traumatic stress disorder (PTSD)

Acute stress disorder is identified in 13-21% of motor vehicle accidents;^2,3 Individuals with acute stress disorder have an increased risk of developing PTSD; U.S. lifetime PTSD prevalence is approximately 6%^4-7

CHATHAM, N.J., Sept. 27, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a biopharmaceutical company, today announced that the University of North Carolina (UNC) Institute for Trauma Recovery has been awarded a $3 million grant from the Department of Defense (DoD) to investigate the potential of Tonix’s TNX-102 SL (cyclobenzaprine HCl sublingual tablets) to reduce the frequency and severity of adverse effects of acute trauma. Such adverse effects include acute stress reaction (ASR), acute stress disorder (ASD), and posttraumatic stress disorder (PTSD). ASR refers to the body’s immediate response to trauma, whereas ASD represents the short-term effects of trauma, and PTSD represents the long-term effects of trauma.

“In addition to emergency care to treat and help patients recover from physical wounds, whether in the emergency room or on the battlefield, we must also address the unmet need for treatment options to address ‘invisible wounds’ that survivors may experience following a traumatic event,” said Samuel McLean, M.D., Professor of Psychiatry and Emergency Medicine at the UNC School of Medicine at UNC, School of Medicine, and lead principal investigator of the proposed study. “To address these needs, we are investigating TNX-102 SL as a potential treatment for patients who experience trauma and traumatic stress.”

The proposed 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 after a motor vehicle collision. The trial will enroll approximately 180 trauma survivors at study sites around the U.S. Participants will be randomized in the emergency department to receive a two-week course of either TNX-102 SL or placebo.

Initiation of patient enrollment in the proposed investigator sponsored OASIS trial is anticipated in the beginning of 2024, subject to Investigational New Drug (IND) application submission and U.S. Food and Drug Administration (FDA) clearance.

The OASIS trial will build upon a foundation of knowledge and infrastructure developed through the UNC-led, $40 million AURORA initiative. The AURORA study is a major national research initiative to improve the understanding, prevention, and recovery of individuals who have experienced 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 health care arm of Google’s parent company Alphabet.

“No medications are currently available at or near the point of care to treat patients suffering from traumatic events and support long-term health, whether U.S. military exposed to life-threatening events or civilians experiencing traumatic events such as motor vehicle collisions,” said Seth Lederman, M.D., Chief Executive Officer of Tonix. “Acute stress reaction and posttraumatic stress symptoms are common among civilian motor vehicle collision survivors. The AURORA study, which has collected thousands of data points from motor vehicle collisions, will allow us to better investigate the correlation between motor vehicle collisions and the emergence of acute stress disorder or PTSD symptoms. And leveraging support from the AURORA study and utilizing the DoD’s non-dilutive capital to primarily fund OASIS allows Tonix and UNC to streamline trial efficiency, reduce costs and increase trial power through enriching the target patient population.”

Added Brandon Staglin, President of One Mind, “For individuals who experience trauma and traumatic stress, the need for effective treatments is an urgent one. The OASIS trial’s focus on evaluating a promising potential treatment option exemplifies the kind of evidence-based outcomes One Mind and our partners hoped to achieve as part of the AURORA initiative’s broader efforts to improve the lives of trauma survivors.”

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.⁵ In the U.S. alone, one-third of emergency department visits (40-50 million patients per year) involve evaluation after trauma exposures, and in a 2014 study involving 3,157 US veterans, 87% reported exposure to at least one potentially traumatic event during their service.⁸ Moreover, as many as 500,000 U.S. troops who served in wars between 2001 and 2015 were diagnosed with PTSD.⁹

About TNX-102 SL in Post-Traumatic Stress Disorder

Sleep disturbances in PTSD are a potential target for pharmacotherapy. TNX-102 SL is a sublingual formulation of cyclobenzaprine designed for once-daily bedtime dosing and rapid transmucosal absorption such that cyclobenzaprine plasma levels rapidly rise during the onset of sleep and first four hours of sleep, then rapidly fall through the second half of sleep through awakening. Cyclobenzaprine has potent binding and antagonist activity at 5-HT_2A, α₁-adrenergic, H₁-histaminergic, and M₁ muscarinic receptors, each of which play roles in the pharmacological management of insomnia. The sublingual transmucosal formulation of cyclobenzaprine is designed to bypass first-pass hepatic metabolism, increasing the ratio in plasma of the parent cyclobenzaprine to the long-lived active metabolite, norcyclobenzaprine, which has a longer half-life and consequently less circadian variation with once-daily dosing. The use of TNX-102 SL 5.6 mg administered daily at bedtime to reduce PTSD symptoms and improve sleep quality in patients with PTSD is supported by the results of a Phase 2 trial (AtEase NCT02277704 in military-related PTSD) and two Phase 3 trials (HONOR or NCT03062540 in military-related PTSD and RECOVERY or NCT03841773 in PTSD). ^10-12 In each of these studies, early improvements in sleep were associated with TNX-102 SL treatment as measured by the PROMIS sleep disturbance (SD) scale. Moreover, in AtEase and HONOR, early and sustained improvement in sleep were associated with TNX-102 SL treatment by the Clinician Administered PTSD Scale (CAPS-5)¹³ “sleep disturbance” item. Primary analyses comparing change from baseline CAPS-5 total severity between TNX-102 SL 5.6 mg and placebo at week 12 were not significant in AtEase, HONOR or RECOVERY. However, in HONOR and RECOVERY at week 4, TNX-102 SL treatment was associated with an improvement in CAPS-5 total severity as compared to placebo. Moreover, secondary analyses in all three studies showed TNX-102 SL treatment was associated with benefits on the patient global impression of change (PGIC), indicating that across studies TNX-102 SL treated patients self-reported greater symptom improvement than those treated with placebo. The most common side-effects were administration site reactions described as tongue numbness or abnormal taste and reported by approximately 30% of participants. There were no unexpected safety findings. Together these studies, with approximately 650 trauma-exposed patients (included 254 patients treated with TNX-102 SL 5.6 mg), provide preliminary evidence that TNX-102 SL is well-tolerated and may promote recovery from PTSD via a pharmacodynamic mechanism of sleep-dependent emotional memory processing.

About TNX-102 SL

TNX-102 SL is a patented sublingual tablet formulation of cyclobenzaprine hydrochloride which provides rapid transmucosal absorption and reduced production of a long half-life active metabolite, norcyclobenzaprine, due to bypass of first-pass hepatic metabolism. As a multifunctional agent with potent binding and antagonist activities at the 5-HT2A-serotonergic, α1-adrenergic, H1-histaminergic, and M1-muscarinic receptors, TNX-102 SL is in development as a daily bedtime treatment for fibromyalgia, Long COVID (formally known as post-acute sequelae of COVID-19 [PASC]), alcohol use disorder and agitation in Alzheimer’s disease. The United States Patent and Trademark Office (USPTO) issued United States Patent No. 9636408 in May 2017, Patent No. 9956188 in May 2018, Patent No. 10117936 in November 2018, Patent No. 10,357,465 in July 2019, and Patent No. 10736859 in August 2020. The Protectic™ protective eutectic and Angstro-Technology™ formulation claimed in the patent are important elements of Tonix’s proprietary TNX-102 SL composition. These patents are expected to provide TNX-102 SL, upon NDA approval, with U.S. market exclusivity until 2034/2035.

mTNX-1700 (mTFF2-MSA) suppresses tumor growth and increases survival rates in preclinical colorectal cancer models

mTNX-1700 shows single agent activity and additive effects in combination with anti-PD-1

mTNX-1700 targets myeloid-derived suppressor cells (MDSCs) in a novel mechanism to treat cancer

CHATHAM, N.J., Sept. 21, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP), a biopharmaceutical company with marketed products and a pipeline of development candidates, today announced a poster presentation showing research results for mTNX-1700 (murine trefoil factor family member 2- murine serum albumin, or mTFF2-MSA) at the Seventh International Cancer Immunotherapy Conference 2023 (CICON23): Translating Science into Survival, being held September 20-23, 2023, in Milan, Italy. The poster is available under the Scientific Presentations tab of the Tonix website at www.tonixpharma.com.

The poster presentation, titled, “mTFF2-MSA (mTNX-1700) Suppresses Tumor Growth and Increases Survival in Anti-PD-1 Treated CT26.WT Subcutaneous and CT26-Luciferase Orthotopic Syngeneic Colorectal Cancer Models by Targeting MDSCs in BALB/C Mice,” includes data demonstrating that the novel fusion protein, mTNX-1700 has single agent activity and can improve on the therapeutic effects of anti-PD-1 in treating syngeneic mouse models of advanced colorectal cancer. In two models, mTNX-1700 increases survival rates and suppresses tumor growth. Additive tumor growth suppression effects were observed when mTNX-1700 and anti-PD-1 were used in combination.

“mTNX-1700 is a novel fusion protein that has single agent activity and augments PD-1 blockade therapy in combination therapy in advanced and metastatic syngeneic mouse models of colorectal and gastric cancer,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Certain cancers are unresponsive to anti-PD-1 therapy. Despite the significance of PD-1 checkpoint blockade in treating many types of cancer, there’s a need to better understand why some cancers don’t respond and how to make them responsive. We believe these data show the potential of TNX-1700 in treating cancer both as a single agent and in combination with other immuno-oncology drugs, particularly anti-PD-1, and highlight how mTNX-1700 targets MDSCs as a novel mechanism to treat cancer.”

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.¹ 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.² Dr. Wang proposed the concept of employing rTFF2 in combination with other therapies in cancer prevention and early treatment. Dr. Wang presented data at the American Association for Cancer Research (AACR) conference as a collaboration between Tonix and Columbia University in 2020 that includes data from a preclinical study which investigated the role of PD-L1 in colorectal tumorigenesis and evaluated the utility of targeting myeloid-derived suppressor cells (MDSCs) in combination with PD-1 blockade in mouse models of colorectal cancer. The data show that anti-PD-1 monotherapy was unable to evoke anti-tumor immunity in this model of colorectal cancer, but mTFF2-CTP augmented the efficacy of anti-PD-1 therapy. Anti-PD-1 in combination with TFF2-CTP showed greater anti-tumor activity in PD-L1-overexpressing mice.

Research News and Market Data on TNXP

September 18, 2023 7:00am EDT

Oxytocin receptors and CGRP are co-expressed on human trigeminal ganglia neurons and their expression is increased in inflammation

Human tissue data support the proposed mechanism of action of TNX-1900 in treating headache: oxytocin treatment blocks the release of CGRP

CHATHAM, N.J., Sept. 18, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a biopharmaceutical company with marketed products and a pipeline of development candidates, today announced that David C. Yeomans, Ph.D. presented data relevant to the proposed mechanism of TNX-1900 (intranasal potentiated oxytocin) in treating chronic migraine in a poster and an oral presentation at the 2023 International Headache Congress (IHC), being held September 14-17, 2023, in Seoul, South Korea. The poster and oral presentation titled, “Human trigeminal ganglia possess oxytocin receptors on CGRP positive neurons: expression increased by inflammation,” include research sponsored by and licensed to Tonix Pharmaceuticals. Professor Yeomans was a founder of Trigemina, which Tonix acquired, and he remains a consultant to Tonix. A copy of the poster is available under the Scientific Presentations tab of the Tonix Pharmaceuticals corporate website at www.tonixpharma.com.

The presentations show that oxytocin receptors are co-expressed with calcitonin gene-related peptide (CGRP) on human trigeminal ganglia neurons, which is similar to Professor Yeomans’ previous findings in animal trigeminal ganglia. The inflammatory cytokine IL-6 upregulated expression of oxytocin receptors on human trigeminal neurons, consistent with the previously observed impact of inflammation on the potency of oxytocin. In animals, oxytocin has been shown to functionally inhibit the excitability of trigeminal neurons, which is consistent with oxytocin inhibiting the release of CGRP at trigeminal nerve terminals.¹

“In animal studies, oxytocin has been shown to inhibit trigeminal neurons which we believe relates to its mechanism in preventing migraines,”¹ said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “The data presented at 2023 IHC by Professor Yeomans shows that oxytocin receptors are present on human trigeminal ganglia neurons, and that these same neurons express CGRP, a key peptide in the pathogenesis of migraine. These data support the proposed mechanism of TNX-1900, which we believe inhibits the release of CGRP from trigeminal neurons that otherwise would trigger a cascade leading to migraine.”

“Similar to animals, human trigeminal ganglia neurons express oxytocin receptors and also co-express CGRP,” said Professor Yeomans. “In addition, the inflammatory mediator IL-6 induces robust upregulation of oxytocin receptors on human trigeminal ganglia neurons. In the presence of inflammation, which is persistently present in chronic migraine, there is a robust increase in the expression of both oxytocin receptors and CGRP in human trigeminal neurons.”

In February 2023, Tonix initiated enrollment in the Phase 2 ‘PREVENTION’ study of TNX-1900 for the prevention of migraine headache in chronic migraineurs. Topline results from the study are expected in the fourth quarter of 2023. In addition, TNX-1900 is also being evaluated in investigator-initiated Phase 2 trials in adolescent obesity (initiated July 2023), binge eating disorder and social anxiety disorder.

Tosymra Nasal Spray 10 mg is a Proprietary Acute Migraine Treatment Approved Under the 505(b)2 Pathway Based on Bioequivalence to Imitrex (sumatriptan) Injection 4 mg

GlaxoSmithKline Recently Notified FDA that it will Discontinue Imitrex Nasal Spray 5 mg and 20 mg Products after January 2024

CHATHAM, N.J., Sept. 06, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a biopharmaceutical company with marketed products and a pipeline of development candidates, today announced that it is committed to meeting potential increased demand for Tosymra® (sumatriptan) nasal spray 10 mg after GlaxoSmithKline’s (GSK) planned discontinuation of Imitrex (sumatriptan) nasal spray 5 mg and 20 mg products after January, 2024.

On August 8, 2023, GSK informed the U.S. Food and Drug Administration (FDA) of its plan to discontinue Imitrex nasal spray 5 mg and 20 mg doses after January 31, 2024. The notification is posted on the FDA Drug Shortages website.¹ Tonix is preparing for potential increased demand for Tosymra (sumatriptan nasal spray) 10 mg to help avoid possible drug shortages for patients who suffer from migraines. Tosymra nasal spray is approved on the basis of bioequivalence to Imitrex injection 4 mg.

Drug shortages have presented an ongoing challenge for the U.S. healthcare system, reaching near-record levels² in recent months, causing treatment delays and rationing. Tonix is ready to step in to alleviate potential shortages in sumatriptan, a widely used treatment option for acute migraine.

“In response to FDA outreach, we have confirmed our commitment to meet potential increased demand for sumatriptan nasal spray from patients who suffer from migraines,” said Seth Lederman, M.D., President and Chief Executive Officer of Tonix. “While Tosymra nasal spray and Imitrex nasal spray are not substitutable at the pharmacy, we plan to alert providers to the possibility of prescribing Tosymra for patients who may benefit from a nasal spray formulation of sumatriptan.”

The American Headache Society Consensus Statement on migraine treatments recommends that “a non-oral formulation should be used in patients whose attacks are associated with severe nausea or vomiting, who do not respond well to traditional oral treatments, or who have trouble swallowing orally administered medications.”³ Approximately 73% of migraine patients have been reported to experience nausea with or without vomiting during their attacks.⁴

“Intranasal sumatriptan is an important therapy for those who suffer from migraines. We believe Tosymra is differentiated from other intranasal formulations of sumatriptan, which are generic equivalents to Imitrex nasal spray because of its proprietary Intravail® absorption enhancer technology,” said James Hunter, Executive Vice President of Commercial Operations at Tonix Pharmaceuticals and President of Tonix Medicines. “Intravail technology helps the medication absorb into the bloodstream so it can work quickly, providing migraine pain relief in as little as 10 minutes for some patients.”^5,6,7

About Migraine

Nearly 40 million people in the United States suffer from migraine⁸ and it has been recognized as the second leading cause of disability in the world.⁹ Migraine is characterized by debilitating attacks lasting four to 72 hours with multiple symptoms, including pulsating headaches of moderate to severe pain intensity often associated with nausea or vomiting, and/or sensitivity to sound (phonophobia) and sensitivity to light (photophobia).
