Intranasal Oxytocin Blocks the Release of CGRP in Animal Models

Intranasal Oxytocin is the Core Technology of TNX-1900 for Migraine

Oxytocin Treatment Affects a Pathway that is Distinct from the Recently Available CGRP Migraine Treatment Drug Class

CHATHAM, N.J., May 22, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP), a clinical-stage biopharmaceutical company, today announced that it has entered into a research collaboration agreement to evaluate the effect of TNX-1900 (intranasal potentiated oxytocin) on capsaicin- or electrical stimulation-induced forehead dermal blood flow in healthy female human volunteers. Dr. Antoinette Maassen van den Brink, Professor of Neurovascular Pharmacology, Erasmus University Medical Center, will serve as principal investigator for the study.

“Collaborating with Professor Maassen van den Brink is an exciting opportunity to learn about the potential for TNX-1900 for treating migraine, facial pain and other related conditions,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “In animal studies, intranasal oxytocin blocks the release of calcitonin gene-related peptide (CGRP) release from trigeminal neurons.¹ CGRP is released from trigeminal neurons during a migraine attack and several CGRP inhibitors are approved for the treatment of migraine. Both a CGRP inhibitor and a triptan have been successfully tested in the model and have been found to inhibit the forehead dermal blood flow response to capsaicin in migraineurs and healthy volunteers, respectively.^2,3 We look forward to learning the results of TNX-1900 in this proof-of-concept study. Together with other studies, the results will guide future development of this potential non-addictive treatment for migraine and other painful conditions.”

Dr. Maassen van den Brink, the principal investigator of the study said, “The signaling pathways that mediate migraine and facial pain are becoming understood. Oxytocin represents a potential new therapeutic option, targeting a pathway in migraine that is distinct from the recently available CGRP inhibitor migraine treatment drug class.”

In February 2023, Tonix initiated enrollment in its Phase 2 PREVENTION study of TNX-1900 for chronic migraine. The Company expects topline results in the fourth quarter of this year.

About Migraine

Migraine is a neurovascular condition that typically manifests in a throbbing moderate to severe headache which lasts at least four hours, often on one side of the head and aggravated by routine physical activity. It can also be accompanied by nausea, vomiting, visual disturbances, and sensitivity to bright light and loud noises.⁴ Epidemiological studies indicate that globally, approximately 1.2 billion individuals suffer from migraines annually.⁵ In the U.S., approximately 39 million Americans suffer from migraines and among these individuals, approximately four million experience chronic migraines (15 or more headache days per month, at least eight of which are migraines).⁵ The current FDA approved drugs for migraine prevention in chronic migraine include Botox^® (onabotulinumtoxin), and the anti-CGRP/CGRP-receptor monoclonal antibodies Aimovig^® (erenumab), Vyepti^® (eptinezumab), Ajovy^® (fremanezumab) and Emgality^® (galcanezumab).

About TNX-1900

TNX-1900 (intranasal potentiated oxytocin) is a proprietary formulation of oxytocin in development as a candidate for prevention of chronic migraine and other conditions. In 2020, TNX-1900 was acquired from Trigemina, Inc. who had licensed the technology underlying the composition and method from Stanford University. TNX-1900 is a drug-device combination product, based on an intranasal actuator device that delivers oxytocin into the nasal cavity. Oxytocin is a naturally occurring human peptide hormone that also acts as a neurotransmitter in the brain. Oxytocin has no recognized addiction potential. It has been observed that low oxytocin levels in the body are associated with increases in migraine headache frequency, and that increased oxytocin levels are associated with fewer migraine headaches. Certain other chronic pain conditions are also associated with decreased oxytocin levels. Migraine attacks are caused, in part, by the activity of pain-sensing trigeminal neurons which, when activated, release calcitonin gene-related peptide (CGRP) which binds to receptors on other nerve cells and starts a cascade of events that is believed to result in migraine. Oxytocin when delivered via the nasal route, concentrates in the trigeminal system⁶ resulting in binding of oxytocin to receptors on neurons in the trigeminal system, inhibiting the release of CGRP and transmission of pain signals returning from the site of CGRP release.¹ Blocking CGRP release is a distinct mechanism compared with CGRP receptor antagonist and anti-CGRP antibody drugs, which block the binding of CGRP to its receptor, or bind to the peptide CGRP. With TNX-1900, the addition of magnesium to the oxytocin formulation enhances oxytocin receptor binding⁷ as well as its inhibitory effects on trigeminal neurons and resultant craniofacial analgesic effects, as demonstrated in animal models.⁸ Intranasal oxytocin has been shown to be well tolerated in several clinical trials in both adults and children⁹. Targeted nasal delivery results in low systemic exposure and lower risk of non-nervous system, off-target effects, which could potentially occur with systemic CGRP receptor antagonists and anti-CGRP (receptor) antibodies¹⁰. For example, CGRP has roles in dilating blood vessels in response to ischemia, including in the heart. The Company believes nasally targeted delivery of oxytocin could translate into selective blockade of CGRP release from neurons in the trigeminal ganglion and not throughout the body, which could be a potential safety advantage over systemic CGRP inhibition. In addition, daily dosing is more rapidly reversible, in contrast to monthly or quarterly dosing, as is the case with anti-CGRP antibodies, giving physicians and their patients greater control. In addition to chronic migraine, TNX-1900 will be developed for treatment of episodic migraine, craniofacial pain conditions, binge eating disorder, and insulin resistance. Tonix also has a license with the University of Geneva to use TNX-1900 for the treatment of insulin resistance and related conditions.

Research Supports Direct Role for Restoring Neuroplasticity and Upsets Previously Held Beliefs About the Significance of Neurotransmitters in Treating Depression

Findings Explain Why Tianeptine Is Not Associated with Sexual Dysfunction and Weight Gain

Mechanism Supports Development of TNX-601 ER for a Broad Range of Neurodegenerative Diseases and Psychiatric Disorders

CHATHAM, N.J., May 17, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced the molecular mechanism of action of tianeptine, the active ingredient of TNX-601 ER (tianeptine hemioxalate extended-release tablets), currently in Phase 2 clinical development for the treatment of major depressive disorder (MDD)^*. Based on pharmacology and medicinal chemistry experiments, scientists at Tonix have established that tianeptine is an agonist for the nuclear peroxisome proliferator-activated receptor (PPAR) isoforms PPAR-β/δ and PPAR-γ, and tianeptine’s effects on these PPAR isoforms account for its ability to induce neuroplasticity in cultured neurons.

The findings upset a long-held belief that the only way to restore the connectivity of neurons damaged in the state of depression was to increase the synaptic levels or activity of neurotransmitters such as the monoamines serotonin, norepinephrine, and dopamine. The new findings show that selective activation of nuclear PPAR-β/δ and PPAR-γ in neurons and supporting glia appears to be a more direct mechanism to achieve the goal of restoring neuronal connectivity, which is called neuroplasticity. Drugs that restore neuroplasticity are called plastogens.^1-3 Consequently, tianeptine is a plastogen that acts directly on nuclear receptors that regulate gene expression in neurons and microglia.

“The discovery that tianeptine stimulates neuroplasticity by activating certain PPAR isoforms could lead to a paradigm shift in designing new antidepressants, and change the relative reliance developers place on targeting synaptic neurotransmitter levels and activity,” said Stephen Stahl, M.D., Ph.D., Adjunct Professor of Psychiatry at the University of California San Diego, Chairman of Neuroscience Education Institute, author of the bestselling clinical manual, Essential Psychopharmacology Prescriber’s Guide, and consultant to Tonix. “This may lead to better pharmacological treatments for depression and for a range of neurodegenerative diseases in which neuronal connections are atrophying and the need to restore the connectivity is paramount to achieving more positive and more sustainable outcomes. Tianeptine avoids some of the more intolerable side effects of the traditional antidepressants because it cuts in line and intervenes downstream from the monoamine transporters and receptors.”

The new research provides clarity on why tianeptine does not cause sexual dysfunction, weight gain, or several other treatment-limiting toxicities associated with traditional antidepressants. Tianeptine treats depression by activating select nuclear PPAR isoforms, and has little to do with monoaminergic neurotransmitters, which are known to be implicated in the most frequently cited side effects of most marketed antidepressants. Key experiments were performed by scientists at Tonix’s Research and Development Center (RDC) in Frederick, Maryland.

“Understanding the mechanism of action of a molecule generally speeds its development and often points the way to broader clinical application,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Despite its success in treating depression outside of the U.S. for more than 30 years, tianeptine’s mechanism has remained obscure. Pioneering studies by Prof. Bruce McEwen, Ph.D. at Rockefeller University revealed that tianeptine stimulates stress-atrophied neurons to form new connections.¹ Subsequently, Prof. Ronald Duman, Ph.D. at Yale University discovered that enhancing these connections is a common principle underlying the therapeutic effects of traditional antidepressants, which only act indirectly on neuroplasticity by changing the level and activity of synaptic neurotransmitters.”⁴

“In animal models, tianeptine restores neuroplasticity and reverses stress-induced impairments through activation of select nuclear PPAR isoforms without modulating synaptic monoamine neurotransmitters,”¹ said Gregory Sullivan, M.D., Chief Medical Officer of Tonix Pharmaceuticals. “Tianeptine mimics naturally occurring polyunsaturated fatty acid in binding to PPARs.⁵ When compared to the traditional classes of antidepressants (SSRIs, tricyclics, etc.), the tianeptine sodium immediate release products available outside of the U.S. demonstrate comparable efficacy⁶ and decreased side effects including sexual dysfunction^7-9, derangement of sleep architecture¹⁰, sedating effects¹¹ despite anxiolysis, weight gain even with long term treatment¹², and cognitive impairment.”^11, 13-15

Dr. Sullivan continued, “Regarding potential future indications beyond our current program in MDD, the proposed mechanism is consistent with the clinical effects of tianeptine in promoting cognition in Alzheimer’s disease, Parkinson’s disease and bipolar disorder^14,15 and motivates us to develop TNX-601 ER as a treatment for these and other conditions, in addition to our previously stated objectives to study it in posttraumatic stress disorder (PTSD) and corticosteroid-induced cognitive dysfunction. The PPAR-β/δ target is validated by prior work on agonists treating animal models of neurodegenerative and autoimmune disease of the central nervous system.¹⁶ The PPAR-γ target is validated by prior work treating peripheral diabetes in animals and as FDA-approved drugs, and the concept that Alzheimer’s can be considered a form of diabetes that affects the CNS, or type-III diabetes.”¹⁷

Dr. Sullivan noted that the new Tonix findings about tianeptine’s mechanism dispel the notion that tianeptine’s weak µ-opioid receptor activity was central to its mechanism of treating depression.¹⁸ This hypothesis was proposed based on results in the forced swim test (FST) using high-dose tianeptine in mice.¹⁹ “Our work found no connection between tianeptine’s neuroplastic effects on cultured neurons and its weak µ-opioid receptor agonism,” Dr. Sullivan said. “In fact, we have identified a new chemical entity related to tianeptine, TNX-4300, that restores neuroplasticity in cultured neurons and is free from µ-opioid receptor activity.”

Tonix is planning to submit data supporting tianeptine’s mechanism of action for presentation at upcoming scientific conferences and for publication in peer reviewed journals.

About Depression

According to the National Institute of Mental Health, an estimated 21 million adults in the U.S. in 2020 experienced at least one major depressive episode¹, with highest prevalence among individuals aged 18-25 at a rate of 17.0%. For approximately 2.5 million adults in the U.S., adjunctive therapies are necessary for depression treatment.^2,3 Depression is a condition characterized by symptoms such as a depressed mood or loss of interest or pleasure in daily activities most of the time for two weeks or more, accompanied by appetite changes, sleep disturbances, motor restlessness or retardation, loss of energy, feelings of worthlessness or excessive guilt, poor concentration, and suicidal thoughts and behaviors. These symptoms cause clinically significant distress or impairment in social, occupational, or other important areas of functioning. The majority of people who suffer from depression do not respond adequately to initial antidepressant therapy.⁴

About TNX-601 ER

TNX-601 ER (tianeptine hemioxalate extended-release tablets) is a novel oral formulation of tianeptine designed for once-daily daytime dosing in development as a candidate for the treatment for MDD, posttraumatic stress disorder, and neurocognitive dysfunction associated with corticosteroid use. Tianeptine sodium (amorphous) immediate release (dosed 3 times daily) was first marketed for depression in France in 1989 and has been available for decades in Europe, Russia, Asia, and Latin America for the treatment of depression. Tianeptine sodium has an established safety profile from decades of use in these jurisdictions. Currently no tianeptine-containing is product approved in the U.S. and no extended-release tianeptine product is approved in any jurisdiction. Tonix discovered a novel oxalate salt of tianeptine that may provide improved stability, consistency, and manufacturability compared to known salt forms of tianeptine. In animal models, tianeptine restores dendritic arborization of pyramidal neurons in the CA3 region of hippocampus and in the dentate gyrus region promotes new neuron formation and integration into hippocampal networks.¹ Tianeptine’s enhancement of neuroplasticity in animal models of stress is believed to be mediated by activation of PPAR isoforms PPAR-β/δ and PPAR-γ, which makes TNX-601 ER’s properties distinct from traditional monoaminergic antidepressants in the U.S. and contributes to its potential for clinical indications beyond MDD and stress disorders. Tianeptine and its MC5 metabolite are also weak mu-opioid receptor (MOR) agonists that present a potential abuse liability if illicitly misused in large quantities (typically abused at 8-80 times the therapeutic dose on a daily basis²). In patients who were prescribed tianeptine for depression, the French Transparency Committee found an incidence of misuse of approximately 1 case per 1,000 patients treated³ suggesting low abuse liability when used at the antidepressant dose in patients prescribed tianeptine for depression. Clinical trials have shown that cessation of a therapeutic course of tianeptine does not appear to result in dependence or withdrawal symptoms following 6-weeks^4-8, 3-months⁹, or 12-months¹⁰ of treatment. The ER formulation of TNX-601 includes several potentially abuse deterrent ingredients include gel forming polymers which impede extraction. In addition, the tablet’s hardness makes it difficult to crush, cut or grind to fine particle size, which potentially hinders efforts to misuse by insufflation or intravenous routes. Tianeptine’s reported pro-cognitive and anxiolytic effects as well as its ability to attenuate the neuropathological effects of excessive stress responses suggest that it may also be used to treat posttraumatic stress disorder (PTSD), and neurocognitive dysfunction associated with corticosteroid use. TNX-601 ER is expected to have patent protection through 2037.

Topline Results Expected in Fourth Quarter 2023 for Potentially Confirmatory Phase 3 Trial of TNX-102 SL for Fibromyalgia

Potentially Pivotal Phase 2 Trial of TNX-601 ER for Major Depressive Disorder (MDD) Enrolling; TNX-601 ER Represents an Innovative Approach for MDD through Restoration of Neuroplasticity and Neurogenesis

Cash and Cash Equivalents of Approximately $72.0 Million at March 31, 2023

CHATHAM, N.J., May 08, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced financial results for the first quarter ended March 31, 2023, and provided an overview of recent operational highlights.

“With much achieved already, we expect 2023 will continue to serve as an important milestone year for Tonix,” said Seth Lederman, M.D., Chief Executive Officer of Tonix. “The prioritization of key programs in our pipeline highlights our commitment to helping bring relief and value to patients suffering from diseases with limited or insufficient therapeutic options. We are pleased with the enrollment in our current RESILIENT Phase 3 study for TNX-102 SL (cyclobenzaprine HCl sublingual tablets) in fibromyalgia. We are looking forward to topline results from the trial in the fourth quarter of this year. If successful, we believe it will be the second and final adequate and well-controlled efficacy trial required for filing a New Drug Application (NDA) for approval by the U.S. Food and Drug Administration (FDA). Moreover, we believe we have satisfied all the other clinical and non-clinical requirements for an NDA submission. In addition, we are excited to have initiated enrollment in the potentially pivotal UPLIFT Phase 2 study of TNX-601 ER (tianeptine hemioxalate extended release tablets) for major depressive disorder (MDD). TNX-601 ER represents a novel approach to treating depression in the U.S., since the active ingredient tianeptine restores neuroplasticity and neurogenesis rather than modulating neurotransmitter levels and activity.”

Recent Highlights—Key Product Candidates*

Central Nervous System (CNS) Pipeline

TNX-102 SL: small molecule for the management of fibromyalgia (FM)

• In March 2023 at the 5^th International Congress on Controversies in Fibromyalgia, the Company presented positive efficacy and safety data from Phase 3 RELIEF Study of TNX-102 SL for the management of fibromyalgia. Titled “Efficacy and Safety of TNX-102 SL (Sublingual Cyclobenzaprine) for the Treatment of Fibromyalgia: Results from the Randomized, Placebo Controlled RELIEF Trial”, the presentation displayed the data that TNX-102 SL met its pre-specified primary endpoint in the Phase 3 RELIEF trial, significantly reducing daily pain compared to placebo (p=0.01) in participants with fibromyalgia. In addition, TNX-102 SL was well tolerated with the most common adverse event associated with active treatment being oral numbness or hypoaesthesia, an administration site reaction that is typically transient, was never rated as severe, and led to only one discontinuation.
• The Company recently announced new plans to eliminate the interim analysis to streamline the ongoing Phase 3 RESILIENT trial and to provide topline data in the fourth quarter of 2023. Target enrollment for the TNX-102 SL fibromyalgia study remains approximately 470 participants.

TNX-102 SL for the treatment of Fibromyalgia-Type Long COVID, also known as Post-Acute Sequelae of COVID-19 (PASC)

• In April 2023, enrollment of 63 participants was completed in the PREVAIL study, a Phase 2 study of TNX-102 SL for fibromyalgia-type Long COVID.
• Topline results from the PREVAIL Phase 2 trial are expected in the third quarter of 2023.
• In February 2023 at a virtual event co-hosted by BIO and Solve M.E. titled, “Long COVID: What Will it Take to Accelerate Therapeutic Progress?”, the Company presented its analysis that the majority of Long COVID patients present with a constellation of symptoms including multisite pain, fatigue, sleep disorders and cognitive dysfunction or brain fog. These symptoms overlap with fibromyalgia and chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME). Fibromyalgia-type Long COVID, like fibromyalgia and CFS/ME, appears to be one of several chronic overlapping pain conditions that have in common the neurological process called central sensitization.

TNX-601 ER: a once-daily orally-administered small molecule for the treatment of MDD, Posttraumatic Stress Disorder (PTSD), neurocognitive dysfunction associated with corticosteroid use and potentially Alzheimer’s disease

• In March 2023, enrollment was initiated in the potentially pivotal Phase 2 ‘UPLIFT’ Study for the treatment of MDD. Results from a planned interim analysis are expected to be released in the fourth quarter of 2023.
• TNX-601 ER represents a novel approach to treating depression in the U.S., since the active ingredient tianeptine induces a neuroprotective and resilient phenotype in both neurons and microglia under conditions of stress. The Phase 2 UPLIFT study is a double-blind, randomized, multicenter, placebo-controlled study to evaluate the efficacy and safety of TNX-601 ER taken orally once-daily for 6 weeks to treat MDD. It is a parallel design study with two arms, a TNX-601 ER 39.4 mg arm and a placebo arm. A total of 300 participants will be randomized in a 1:1 ratio into the two arms across approximately 30 U.S. sites, enrolling adult patients 18-65 years old. The primary efficacy endpoint is mean change from baseline in the Montgomery-Åsberg Depression Rating Scale (MADRS) total score at Week 6.

TNX-1900 (intranasal potentiated oxytocin): small peptide for migraine, craniofacial pain, insulin resistance and related disorders, and obesity-associated binge eating disorder

• In February 2023, enrollment began in the Phase 2 PREVENTION study of TNX-1900 for the prevention of migraine headache in chronic migraineurs. The double-blind, placebo-controlled study has a target enrollment of 150 participants at approximately 25 sites across the U.S, with topline results expected in the fourth quarter of 2023.
• In January 2023, data from clinical and nonclinical studies were presented at the 16^th Annual Headache Cooperative of the Pacific (HCOP) Winter Conference by collaborator Professor David Yeomans. The oral presentation titled, “Primary vs Secondary Sex Hormones and Migraine,” includes research sponsored and licensed by Tonix. Preliminary results from a positron emission tomography study in humans showed that intranasal delivery of a radioisotope of magnesium-potentiated oxytocin is delivered to the trigeminal ganglia, which have known roles in migraine headaches. In addition, preliminary results of data collected from isolated human trigeminal ganglia neurons in vitro show co-expression of oxytocin receptors and calcitonin gene-related peptide, which are believed to represent the first observation of oxytocin receptors in human trigeminal ganglia. Furthermore, the presentation highlights data which suggest a sex difference in oxytocin potency.

TNX-1300 (recombinant double mutant cocaine esterase): biologic for life-threatening cocaine intoxication

• Tonix expects to initiate a potentially pivotal, Phase 2 clinical study of TNX-1300 for the treatment of cocaine intoxication in the third quarter of 2023.
• As previously disclosed, in 2022, Tonix received a Cooperative Agreement grant from the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health (NIH), to support development of TNX-1300.
• TNX-1300 has been granted Breakthrough Therapy designation by the FDA.

Rare Disease Pipeline

TNX-2900 (intranasal potentiated oxytocin): small peptide for the treatment of Prader-Willi syndrome (PWS)

• TNX-2900 has been granted Orphan Drug designation from the FDA for the treatment of PWS.
• In March 2023, Tonix delivered a presentation titled, “TNX-2900 (Intranasal Oxytocin + Magnesium) in Development for the Treatment of Hyperphagia in Adolescents and Young Adults with Prader-Willi Syndrome” at the Rare Disease Innovation and Partnership Summit. The presentation displayed data showing the enhancing effects of magnesium (Mg²⁺) on the activation of oxytocin receptors. The Mg²⁺ enhanced formulation of intranasal oxytocin is the basis for TNX-2900, in development to treat hyperphagia, or pathological over-eating, in children and young adult patients with PWS.

Immunology Pipeline

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

• In May 2023, the IND for prevention of organ rejection in patients receiving a kidney transplant was cleared by FDA. A First-in-Human Phase 1 study is expected to initiate in the third quarter of 2023.The first indication for TNX-1500 will be prophylaxis of organ rejection in adult patients receiving a kidney transplant, but multiple additional indications are possible, including autoimmune diseases.
• Tonix announced a research agreement with Boston Children’s Hospital to study TNX-1500 for the prevention of graft-versus-host diseases (GvHD) after hematopoietic stem cell transplantation (HCT) in animals. HCT from unrelated donors is a component of the treatment protocol for several hematologic malignancies, but GvHD complicates treatment and limits the success of engraftment after HCT. In April 2023, the Company announced the online publication of two papers in the American Journal of Transplantation by faculty at the Center for Transplantation Sciences, Massachusetts General Hospital (MGH) in collaboration with Tonix Pharmaceuticals^1,2. The publications include data demonstrating that TNX-1500 showed activity in preventing organ rejection and was well tolerated in non-human primates. To date, there has not been a humanized anti-CD40L antibody that can effectively prevent transplant rejections with an acceptable level of safety.

Infectious Disease Pipeline

TNX-801 (live horsepox virus vaccine for percutaneous administration): vaccine to protect against smallpox and monkeypox (mpox) designed as a single-administration vaccine to elicit T cell immunity.

• As previously announced, a Phase 1 study is expected to start in the second half of 2023.
• In January 2023, the Company appointed Zeil Rosenberg, M.D., M.P.H., as Executive Vice President, Medical for Infectious Disease programs. Dr. Rosenberg is responsible for leading the Company’s clinical development efforts for vaccines, including TNX-801.
• A publication describing the activity of TNX-801 to protect non-human primates against a lethal challenge with intra-tracheal monkeypox was published in the peer-reviewed journal, Viruses³.

Recent Highlights—Corporate and Other

• In April 2023, Tonix announced it is reallocating resources and cash to streamline its pipeline and focus on its mid- and late-stage clinical programs within its core CNS portfolio. The pipeline realignment prioritizes key near-term value drivers, reduces investment in several longer-term programs, particularly COVID-19-related studies, and delays the start of a PTSD study in Kenya.

Recent Highlights—Financial

As of March 31, 2023, Tonix had $72.0 million of cash and cash equivalents, compared to $120.2 million as of December 31, 2022. Net cash used by financing activities was approximately $11.5 million for first quarter 2023, compared to net cash provided by financing activities of $13.1 million for the same period in 2022.

On April 8, 2020, the Company entered into a sales agreement (the “Sales Agreement”) with AGP of up to $320.0 million in at-the-market offerings (“ATM”) sales. During the quarter ended March 31, 2023, the Company sold approximately 3.2 million shares of common stock under the Sales Agreement, for net proceeds of approximately $2.0 million. Subsequent to March 31, 2023, the Company has sold 0.9 million shares of common stock under the Sales Agreement, for net proceeds of approximately $0.5 million.

In January 1, 2023, the Company repurchased 16,700,269 shares of common stock under its share repurchase programs at an average price per share of $0.82 for a gross aggregate cost of approximately $13.6 million. 

Cash used in operations was approximately $32.9 million for the first quarter ended March 31, 2023, compared to $31.0 million for the first quarter ended March 31, 2022.

Cash used by investing activities for the first quarter ended March 31, 2023, and 2022 was approximately $3.8 million and $20.2 million, respectively, related to the purchase of property and equipment.

First Quarter 2023 Financial Results

R&D expenses for the first quarter 2023 were $26.5 million, compared to $18.4 million for the same period in 2022. As planned, R&D expenses will be increasing during 2023 as we move our clinical development programs forward and invest in our development pipeline.

G&A expenses for the first quarter 2023 were $7.4 million, compared to $8.0 million for the same period in 2022. The decrease is primarily due to decreased employee-related and financial reporting expenses.

Net loss was $33.0 million, or $0.52 per share, basic and diluted, for the first quarter 2023, compared to net loss of $26.4 million, or $1.61 per share, basic and diluted, for the same period in 2022. The basic and diluted weighted average common shares outstanding for the first quarter 2023 was 63,352,898 compared to 16,445,010 shares for the same period in 2022.

Multiple Additional Indications Possible, Including Autoimmune Diseases: Pipeline within a Product

Published Non-Human Primate Studies Show TNX-1500 Prolongs Renal and Heart Allograft Survival

Phase 1 Clinical Trial of TNX-1500 Expected to Start Third Quarter 2023

CHATHAM, N.J., May 04, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP), a clinical-stage biopharmaceutical company, today announced the U.S. Food and Drug Administration (FDA) has cleared the Investigational New Drug (IND) application to support a Phase 1 clinical trial with TNX-1500 (anti-CD40L monoclonal antibody [mAb]). The first indication Tonix is seeking for TNX-1500 is the prevention of organ rejection in patients receiving a kidney transplant. The Company expects to initiate enrollment in the Phase 1 study in the third quarter of 2023.

The IND application for TNX-1500 was supported by preclinical allotransplantation studies conducted at the Massachusetts General Hospital (MGH), led by principal investigators Tatsuo Kawai, MD, PhD, A. Benedict Cosimi Chair in Transplant Surgery, MGH and Professor of Surgery, Harvard Medical School (HMS), and Richard N. Pierson III, M.D., scientific director of the Center for Transplantation Sciences in the Department of Surgery at MGH and Professor of Surgery at HMS.

“This is an important milestone as we advance TNX-1500 into clinical development,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Despite advancements in the field of solid organ transplantation, there remains a significant need for new treatments with improved activity and tolerability to prevent organ transplant rejection. Our primary focus of early development will be allotransplantation in which the donor organ comes from another human. However, in the longer term we hope to develop TNX-1500 for xenograft transplantation in which the donor organ comes from a genetically engineered pig.”

Dr. Lederman continued, “We view TNX-1500 as a pipeline within a product, because of its potential to treat a number of autoimmune diseases. Anti-CD40L mAbs have demonstrated activity and tolerability in autoimmune diseases like systemic lupus erythematosus and Sjögren’s Syndrome. An anti-CD40L mAb is also in development for multiple sclerosis. CD40L is a member of the TNFα super gene family. Other TNFα super gene members have been the targets of successful mAb therapeutics: TNFα and RANKL for autoimmune diseases and osteoporosis, respectively. Still other TNFα super gene family members are targeted by mAbs in development including TNF-like ligand 1A (TL1A) and CD30L for ulcerative colitis and Ox40L for atopic dermatitis.”

TNX-1500 is a third generation anti-CD40L mAb that has been designed by protein engineering to decrease FcγRIIA binding and to therefore reduce the potential for thrombosis. Preclinical studies in non-human primates demonstrated that TNX-1500 showed activity in preventing allograft organ rejection and was well tolerated^1,2.

About TNX-1500

TNX-1500 (Fc-modified anti-CD40L mAb) is a humanized monoclonal antibody that interacts with the CD40-ligand (CD40L), which is also known as CD154. TNX-1500 is being developed for the prevention of allograft and xenograft rejection, for the treatment of autoimmune diseases and for the prevention of graft-versus-host disease (GvHD) after hematopoietic stem cell transplantation (HCT). A Phase 1 study of TNX-1500 is expected to be initiated in the third quarter of 2023. Two articles have recently published in the American Journal of Transplantation that demonstrate TNX-1500 prolongs non-human primate renal and heart allograft survival^1,2.
