Topline Results Expected Third Quarter 2023

Long COVID Afflicts Approximately 19% of Patients Following COVID-19¹, and is Expected to be a Global Health Burden

Fibromyalgia-Type Long COVID with Multi-Site Pain Affects Approximately 40% of Long COVID Patients

CHATHAM, N.J., Aug. 07, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a biopharmaceutical company, today announced the completion of the clinical phase of the Phase 2 proof-of-concept PREVAIL study of TNX-102 SL as a potential treatment for fibromyalgia-type Long COVID. Topline results for the PREVAIL study are expected in the third quarter of 2023.

“Approximately 40% of U.S. Long COVID patients have fibromyalgia-like multi-site pain symptoms based on our observational studies of Long COVID patients from the TriNetX claims database,”^2,3 said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “In addition to multi-site pain, these individuals often suffer from one or more other symptoms typically associated with fibromyalgia such as fatigue, sleep disturbance, and brain fog. We have termed this subgroup, ‘Fibromyalgia-type Long COVID.’ Given our encouraging results with TNX-102 SL as a potential treatment for fibromyalgia⁴, we are testing TNX-102 SL as a bedtime medicine for the management of Fibromyalgia-type Long COVID. In completing this clinical milestone, marked by the last enrolled patient finishing their final visit, we can now begin to look forward to topline results from the 63-patient PREVAIL study later this quarter.”

Dr. Lederman continued, “TNX-102 SL improves sleep quality in fibromyalgia, and we believe this is the mechanism by which TNX-102 SL improves other symptoms, like multi-site pain.⁵ Recently, the U.S. National Institutes of Health (NIH) has identified improving sleep quality as a target for potential therapeutics for Long COVID^6,7,8, consistent with the proposed mechanism of TNX-102 SL.

“Common symptoms of Long COVID, including multi-site pain, fatigue, unrefreshing sleep, and cognitive dysfunction, or ‘brain fog,’ are also hallmarks of conditions like fibromyalgia and chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME),”⁹ said Herbert Harris, M.D., Ph.D., Executive Vice President and Head of Translational Medicine of Tonix Pharmaceuticals. “Defining subgroups of Long COVID patients that overlap with fibromyalgia and CFS/ME is expected to facilitate the development of new treatments.⁴ It can be challenging to distinguish fibromyalgia and CFS/ME clinically, given the high level of symptom overlap between them. Each of these conditions is defined by a constellation of symptoms, and there is no widely recognized diagnostic laboratory test that distinguishes them.”

Dr. Harris continued, “The recent identification of Long COVID subgroups in the National Institutes of Allergy and Infectious Diseases (NIAID)-sponsored RECOVER study¹⁰ was an important step. In their recent publication, cluster analysis of the symptom frequencies in the RECOVER study identified four subgroups of Long COVID patients. Cluster #4 represented approximately one-quarter of the population (28%) and reported the highest frequencies of pain (back pain (58%), joint pain (64%) or muscle pain (60%)), high frequencies of fatigue (94%) and ’Brain Fog,’ (94%) and a high level of impairment of Quality of Life. We believe Cluster #4 is a subgroup of Long COVID that shares many clinical features with fibromyalgia and may involve common disease mechanisms. We also believe that Cluster #3, representing another approximately 29% of the RECOVER cohort, includes many patients with fibromyalgia-type Long COVID because 100% of that group suffer from ‘Brain Fog’, 94% experience fatigue and approximately one-third experience pain (back pain (32%), joint pain (36%) or muscle pain (34%)).”

Dr. Harris concluded, “With no FDA approved treatment for Long COVID, we understand the need to better understand long COVID and to develop treatments for subgroups of this unserved population of patients. Fibromyalgia has been recognized by the U.S. Food and Drug Administration (FDA) with three approved medicines. Consequently, measuring daily pain is a validated endpoint for FDA registrational studies in fibromyalgia. We believe that daily pain has the potential to be an endpoint for registrational studies in fibromyalgia-like long COVID.”

About the Phase 2 PREVAIL Study

The Phase 2 PREVAIL study is a 14-week double-blind, randomized, multicenter, placebo-controlled study to evaluate the efficacy and safety of TNX-102 SL taken daily at bedtime in patients with multi-site pain associated with post-acute sequelae of SARS-CoV-2 infection (PASC). The trial is being conducted at approximately 30 sites in the U.S. The primary efficacy endpoint will be the change from baseline in the weekly average of daily self-reported worst pain intensity scores at the Week 14 endpoint. Key secondary efficacy endpoints include change from baseline in self-reported scores for sleep disturbance, fatigue, and cognitive function. Topline results are expected in the third quarter of 2023.

For more information, see ClinicalTrials.gov Identifier: NCT05472090.

About Long COVID or Post-Acute Sequelae of COVID-19 (PASC)

Post-acute sequelae of COVID-19, or PASC is the formal name for a condition now widely known as Long COVID. Although most people recover from COVID-19 within weeks of the acute illness, a substantial portion develops a chronic syndrome called Long COVID.¹¹ These individuals experience a constellation of disabling symptoms long past the time of recovery from acute COVID-19. Most Long COVID patients who have been studied appear to have cleared the SARS-CoV-2 infection from their systems. The symptoms of Long COVID can include fatigue, sleep disorders, multi-site pain, fevers, shortness of breath, cognitive impairment described as “brain fog” or memory disturbance, gastrointestinal symptoms, anxiety, and depression. According to the Centers for Disease Control and Prevention (CDC), 1 in 13 adults in the U.S. (7.5%) have Long COVID symptoms.¹ Long COVID is typically associated with moderate or severe COVID-19, but can occur after mild COVID-19 or even after asymptomatic SARS-CoV-2 infection. More than 40% of adults in the United States reported having COVID-19 in the past, and nearly one in five of those (19%) are currently still having symptoms of Long COVID.¹ Long COVID is a chronic disabling condition that is expected to result in a significant global health and economic burden.^12-15 In response to the urgent need for therapies that address Long COVID, Congress awarded $1.15 billion to the National Institutes of Health to study Long COVID in December 2020¹⁶ The U.S. Department of Health and Human Services National Research Action Plan on Long COVID¹⁷, released in August 2022, addresses the overlap of Long COVID with CFS/ME, which, like fibromyalgia, is one of the overlapping chronic pain syndromes with central and peripheral sensitization.¹⁸ A published survey¹⁹ found comparable pain, fatigue, and functional impairment between Long COVID, fibromyalgia, and CFS/ME. This symptom overlap between these conditions has suggested that altered neurologic function is one of the leading hypotheses to explain them.²⁰ While the vaccines available in the U.S., through either FDA approval or under Emergency Use Authorization, have been shown to prevent acute COVID, their ability to prevent Long COVID is unknown. There is currently no approved drug for the treatment of Long COVID. 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 and peripheral sensitization, which is increasingly known by the term nociplastic pain.

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.

Release – Tonix Pharmaceuticals Completes Enrollment in Potentially NDA-Enabling Phase 3 RESILIENT Trial of TNX-102 SL for Management of Fibromyalgia

Posted on August 1, 2023August 1, 2023 by aweinsoff@channelchek.com

Topline Data Expected Fourth Quarter 2023

Final Trial Required for Submission of a New Drug Application, if Successful

CHATHAM, N.J., Aug. 01, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a biopharmaceutical company, today announced that it has completed enrollment of its potentially final, confirmatory Phase 3 RESILIENT trial of TNX-102 SL (cyclobenzaprine HCL sublingual tablets) 5.6 mg in fibromyalgia and expects topline data next quarter. A total of 457 participants were randomized. TNX-102 SL is in development as a non-opioid, centrally acting analgesic, to be taken daily at bedtime for the management of fibromyalgia. If successful, we believe this will be the final, well-controlled efficacy trial required for submission of a New Drug Application (NDA) for approval by the U.S. Food and Drug Administration (FDA).

“The completion of enrollment in our Phase 3 RESILIENT trial is a significant milestone for both Tonix and the fibromyalgia community,” said Seth Lederman, M.D., Chief Executive Officer of Tonix. “Currently-approved treatments have not fully met the needs of fibromyalgia patients and there has not been a new FDA-approved therapy for the condition since 2009. TNX-102 SL has the potential to be a new non-addictive, non-opioid bedtime medication with broad spectrum symptom coverage and which can be used on a chronic basis for the management of fibromyalgia. With all other clinical, nonclinical and CMC requirements for an NDA submission achieved, we are looking forward to the upcoming data readout and an expeditious filing of an NDA.”

In December 2020, Tonix reported positive results from the first Phase 3 study (RELIEF) of TNX-102 SL 5.6 mg for the management of fibromyalgia. 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. Also, when the primary endpoint was analyzed as a ≥30% pain responder analysis, there was a higher rate of responders to TNX-102 SL (47%) than to placebo (35%; p=0.006). TNX-102 SL at 5.6 mg also showed activity in key secondary endpoints demonstrating improvements in sleep quality, mitigation of fatigue, and fibromyalgia-specific global symptomatic and functional recovery. TNX-102 SL was generally safe and well tolerated in patients with fibromyalgia, with overall adverse event profile comparable to prior fibromyalgia studies. The most common treatment-emergent adverse events were oral hypoesthesia, oral paresthesia, and product taste abnormal.

About the Phase 3 RESILIENT Study

The RESILIENT study is a double-blind, randomized, placebo-controlled trial designed to evaluate the efficacy and safety of TNX-102 SL (cyclobenzaprine HCl sublingual tablets) in the management of fibromyalgia. The two-arm trial randomized 457 participants in the U.S. The first two weeks of treatment consist of a run-in period in which participants start on TNX-102 SL 2.8 mg (1 tablet) or placebo. Thereafter, all participants increase their dose to TNX-102 SL 5.6 mg (2 x 2.8 mg tablets) or two placebo tablets for the remaining 12 weeks. The primary endpoint is the daily diary pain severity score change (TNX-102 SL 5.6 mg vs. placebo) from baseline to Week 14 (using the weekly averages of the daily numerical rating scale scores), analyzed by mixed model repeated measures with multiple imputation.

About Fibromyalgia

Fibromyalgia is a chronic pain disorder that is understood to result from amplified sensory and pain signaling within the central nervous system. Fibromyalgia afflicts an estimated 6-12 million adults in the U.S., approximately 90% of whom are women. Symptoms of fibromyalgia include chronic widespread pain, nonrestorative sleep, fatigue, and morning stiffness. Other associated symptoms include cognitive dysfunction and mood disturbances, including anxiety and depression. Individuals suffering from fibromyalgia struggle with their daily activities, have impaired quality of life, and frequently are disabled. Physicians and patients report common dissatisfaction with currently marketed products.

Release – Tonix Pharmaceuticals Announces Enrollment Initiated in the MGH Phase 2 ‘STROBE’ Study of TNX-1900 (Intranasal Potentiated Oxytocin) for the Treatment of Binge-Eating Disorder

Posted on July 31, 2023July 31, 2023 by aweinsoff@channelchek.com

Research News and Market Data on TNXP

July 31, 2023 7:00am EDT

Preliminary Data Show that Oxytocin Decreases Impulsivity and Reduces Food Intake

TNX-1900 (Intranasal Potentiated Oxytocin) May Serve as a Novel Neuroendocrine Treatment for Binge-Eating Disorder

CHATHAM, N.J., July 31, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced that the first participant was enrolled in the investigator-initiated Phase 2 Study of The Results of Oxytocin in Binge Eating ‘STROBE’ study of TNX-1900 (intranasal potentiated oxytocin) for the treatment of binge-eating disorder at the Massachusetts General Hospital (MGH). The aim of the study is to investigate the efficacy and safety of TNX-1900 as a novel therapeutic agent to reduce binge eating frequency in adults with binge-eating disorder. Tonix is supporting the STROBE study through a clinical trial agreement with MGH. MGH is the sponsor of the trial, which is being conducted under an investigator-initiated investigational new drug (IND) application.

The 8-week double-blind, placebo-controlled trial has a target enrollment of at least 60 participants 18-45 years old with binge-eating disorder.

“Binge-eating disorder is identified as a reduced ability to control behavioral impulses and formed habits, disrupting the regulation of food intake and energy balance,”^1-4 said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “While existing treatment options may produce remission from binge eating in some cases, up to 50% of patients continue to engage in binge eating.”^5-7

Elizabeth A. Lawson, M.D., M.M.Sc., Director, Interdisciplinary Oxytocin Research Program in the Neuroendocrine Unit, Department of Medicine, Massachusetts General Hospital and principal investigator of the study added, “Individuals with binge-eating disorder experience loss of control over eating that is thought to be driven by increased hedonic drive to eat as well as impulsivity.^8-10 The oxytocin system has been linked to likelihood of lifetime binge eating in women¹¹, and our preliminary studies of intranasal oxytocin at the dose used in this trial show that oxytocin modulates areas of the brain responsible for hedonic eating and impulse control¹², improves impulsivity¹³, and reduces caloric intake.¹⁴ The goal of the STROBE study is to assess whether 8 weeks intranasal administration of oxytocin will decrease binge eating frequency by lowering the drive to eat and improving impulse control.”

About the Phase 2 STROBE Study

The Phase 2 STROBE study is a randomized, double blind, placebo-controlled study to evaluate the efficacy and safety of TNX-1900 for the treatment of binge-eating disorder in adults. The 8-week trial has a target enrollment of at least 60 participants 18-45 years old with binge-eating disorder. Subjects will be randomized to receive TNX-1900 or placebo and will be studied at Massachusetts General Hospital. Subjects will self-administer TNX-1900 or placebo as two sprays total (one spray in each nostril) up to four times per day for 8 weeks. The primary endpoint is 8-week change from baseline in binge frequency.

For more information, see ClinicalTrials.gov Identifier: NCT05664516

About Binge Eating Disorder

Binge-eating disorder (BED) is a psychiatric illness characterized by frequent episodes of uncontrollable consumption of large amounts of food. It is the most common eating disorder and often leads to obesity-associated complications and later psychopathology¹⁵. BED is characterized by increased homeostatic appetite and sensitivity to reward (including food reward)¹⁶, which may lead to initiation of binge episodes, and a reduced ability to control behavioral impulses and formed habits, creating an imbalance in the sensitive interplay between these bottom-up and top-down processes governing the adaptive regulation of food intake and energy balance^1-4.

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 of 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 headache. Oxytocin when delivered via the nasal route, concentrates in the trigeminal system¹⁷ 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.¹⁸ Blocking CGRP release is a distinct mechanism compared with CGRP antagonist and anti-CGRP antibody drugs, which block the binding of CGRP to its receptor. With TNX-1900, the addition of magnesium to the oxytocin formulation enhances oxytocin receptor binding¹⁹ as well as its inhibitory effects on trigeminal neurons and resultant craniofacial analgesic effects, as demonstrated in animal models²⁰. Intranasal oxytocin has been shown to be well tolerated in several clinical trials in both adults and children²¹. 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 antagonists such as anti-CGRP antibodies²². 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, binge eating disorder, craniofacial pain conditions, 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.

About TNX-2900

TNX-2900 is another intranasal potentiated oxytocin-based therapeutic candidate, being developed for the treatment of Prader-Willi syndrome, or PWS. The technology for TNX-2900 was licensed from the French National Institute of Health and Medical Research. PWS, an orphan condition, is a rare genetic disorder of failure to thrive in infancy, associated with uncontrolled appetite later in childhood.

Reallocating Resources to Development of Single Isomer TNX-4300 (Estianeptine)

Estianeptine in Preclinical Development Has Demonstrated Key Activities Related to in vivo Novel Object Recognition and in vitro Neuroplasticity, Without the µ-Opioid Receptor Activity of Racemic and (R)-Tianeptine

New Findings Support Development of TNX-4300 as a First-in-Class Oral Therapy in Depression, Alzheimer’s Disease and Other Psychiatric and Neurodegenerative Conditions with Memory Deficits

CHATHAM, N.J., July 26, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a biopharmaceutical company, today announced that development of TNX-4300* (estianeptine), the single (S)-isomer of tianeptine will be prioritized over TNX-601 ER*, which is being studied in the Phase 2 UPLIFT¹ trial for the treatment of major depressive disorder (MDD). TNX-4300 is in preclinical development for mood disorders, Alzheimer’s disease and Parkinson’s disease. Recent findings have shown estianeptine possesses the ability to improve memory and cognition in vivo as measured in the rat Novel Object Recognition (NOR) test, and the ability to restore neuroplasticity to neurons in cell culture. The finding that estianeptine is responsible for improving memory and cognition in vivo suggests a role for peroxisome proliferator-activated receptor PPAR-β/δ activation in memory. For these reasons, Tonix intends to accelerate completion of enrollment for the Phase 2 UPLIFT¹ trial to reallocate resources to the preclinical development of TNX-4300 and now expects to report topline data from this study in the fourth quarter of 2023. Tonix is also accelerating completion of enrollment in the RESILIENT study of TNX-102 SL for the management of fibromyalgia so that approximately 450 patients will be enrolled, and topline results are expected in the fourth quarter of 2023.

Racemic tianeptine is an antidepressant that has been marketed outside the U.S. for more than 30 years. Tianeptine is also a racemic drug composed of a 1:1 mixture of two mirror-image isomers. Tonix recently reported that the (S)-isomer (estianeptine) is responsible for its positive effects on neuroplasticity in cell culture, while the (R)-isomer is responsible for racemic tianeptine’s off-target activity on the µ-opioid receptor.^2,3 Tonix also recently reported that estianeptine activates PPAR-β/δ. These activities on molecular targets in neurons and glia in the brain are believed to relate to tianeptine’s ability to restore connectivity between neurons that atrophy in conditions of stress or depression in animal models.⁴ Tianeptine’s mechanism is distinct from traditional antidepressants that alter the level or activity of serotonin, norepinephrine, and dopamine neurotransmitters, which are believed to indirectly induce neurons to make new connections.⁵

“Given the time and expense of developing new drugs, the scientific and clinical advantages of TNX-4300 lead us to focus our efforts on this preclinical program as a potential treatment for mood disorders like depression and neurodegenerative conditions like Alzheimer’s disease,” said Gregory Sullivan, M.D., Chief Medical Officer of Tonix Pharmaceuticals. “The finding that TNX-4300 possesses the desirable attributes of racemic tianeptine and at the same time lacks a measurable opioid liability supports the focus of our resources on this candidate. Multiple studies around the world have already shown that racemic tianeptine is effective in treating depression. However, our in vivo animal studies and in vitro lab studies have indicated that TNX-4300 is potentially a more active and safer drug.”

Dr. Sullivan continued, “TNX-601 ER, which contains racemic tianeptine, has informed the future development of TNX-4300 which contains the single isomer, estianeptine. We believe that estianeptine bypasses the synapse and activates intracellular PPAR-β/δ and PPAR-γ targets. The finding that estianeptine is responsible for tianeptine’s ability to improve memory and cognition in the NOR test implicates PPAR-β/δ activation specifically as a molecular target. This finding is consistent with the impaired memory of mice lacking the PPAR-β/δ gene.”⁸

Tonix has filed patents claiming single (S)-isomer estianeptine, the active ingredient in TNX-4300, which is devoid of activity on the µ-opioid receptor in tissue culture. Tonix has filed patent claims that describe crystalline salt forms of estianeptine that appear well suited to formulation. TNX-4300 is currently in preclinical development for depression, bipolar disorder, Alzheimer’s disease, and Parkinson’s disease. Key experiments were performed by scientists at Tonix’s Research and Development Center (RDC) in Frederick, Maryland.

^*TNX-601 ER and TNX-4300 are investigational new drugs and are not approved for any indication. TNX-601 ER is being developed under an IND. TNX-4300 is at the pre-IND stage of development.

About Tianeptine

Racemic 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 tolerability profile from decades of use in these jurisdictions. Currently no tianeptine-containing product is approved in the U.S. and no extended-release once-daily tianeptine product is approved in any jurisdiction. 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.⁴ 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 is mechanistically distinct from traditional monoaminergic antidepressants marketed in the U.S. and contributes to its potential for clinical indications beyond depression and stress disorders. Tianeptine and its MC5 metabolite are also weak µ-opioid receptor (MOR) agonists that present a potential abuse liability if illicitly misused in large quantities.^3,9 In cases where tianeptine has been abused, the dose has been approximately 8-80 times the therapeutic dose in depression on a daily basis.⁹ 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 treated¹⁰ 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^11-15, 3-months,¹⁶ or 12-months¹⁷ of treatment. Estianeptine is believed to mimic naturally occurring polyunsaturated fatty acid ligands in low affinity interactions with PPAR-β/δ and PPAR-γ. Estianeptine’s activation of nuclear PPAR-β/δ and PPAR-γ receptors appears to be a more direct mechanism to achieve the goal of restoring neuronal connectivity than the active ingredients of current pharmacologic therapies for depression. Tianeptine’s proposed mechanism as a plastogen is consistent with its clinical effects in promoting cognition in depressed patients with Alzheimer’s disease⁵ and in patients with bipolar disorder.⁶ The PPAR-β/δ target is validated by prior work on agonists treating animal models of neurodegenerative and autoimmune diseases of the central nervous system.¹⁸ Alzheimer’s disease has been proposed to be a form of diabetes that affects the CNS, sometimes termed type-III diabetes.”¹⁹The PPAR superfamily plays key roles in metabolic processes, and activation of PPAR-β/δ in brain by tianeptine shows promise to prevent the cognitive dysfunction associated with CNS insulin resistance. Tianeptine’s reported pro-cognitive and anxiolytic effects as well as its ability to attenuate the neuropathological effects of excessive stress responses suggest other potential uses including as a treatment for posttraumatic stress disorder (PTSD), as well as for preventing neurocognitive dysfunction associated with corticosteroid use.

Robert LeBoyer, Senior Vice President, Equity Research Analyst, Biotechnology, Noble Capital Markets, Inc.

Refer to the full report for the price target, fundamental analysis, and rating.

New Tianeptine Data In Memory and Cognition. Tonix announced new preclinical findings for tianeptine, the active molecule in two pipeline products. The two products are TNX-601 EP, in development for major depressive disorder, and TNX-4300, in preclinical development for Alzheimer’s disease, Parkinson’s disease, and mood disorders. The TNX-601 Phase 2 UPLIFT trial is expected to release results in 1Q24.

New Data Supports Previous Tianeptine Findings. As discussed in our Research Note on May 30, Tonix presented data showing that tianeptine restores neuronal sprouting and reconnections in cell culture. The data showed its two isomers have different targets, with the (S)-isomer affecting neuroplasticity, and the (R)-isomer binding to the mu-opioid receptor and causing undesirable off-target effects. A new molecule, TNX-4300 or estianeptine, was developed as a purified version containing only the (S)-isomer.

TNX-4300 is in preclinical development for mood disorders, Alzheimer’s disease and Parkinson’s disease.^* The findings reported today show that tianeptine and estianeptine improve memory and cognition as measured in the rat Novel Object Recognition (NOR) test. The finding that estianeptine is responsible for improving memory and cognition suggests a role for PPAR-β/δ activation in memory.

Tianeptine is an antidepressant that has been marketed outside the U.S. for more than 30 years. Tianeptine is also a racemic drug composed of a 1:1 mixture of two mirror-image isomers. Tonix recently reported that the (S)-isomer (estianeptine) is responsible for its positive effects on neuroplasticity in cell culture, while the (R)-isomer is responsible for racemic tianeptine’s off-target activity on the µ-opioid receptor.^2,3 Tonix also recently reported that estianeptine activates peroxisome proliferator-activated receptors PPAR-β/δ and PPAR-γ. These activities on molecular targets in neurons and glia in the brain are believed to relate to tianeptine’s ability to restore connectivity between neurons that atrophy in conditions of stress or depression in animal models.⁴ Tianeptine’s mechanism is distinct from traditional antidepressants that alter the level or activity of serotonin, norepinephrine, and dopamine neurotransmitters, which are believed to indirectly induce neurons to make new connections.⁵

“The memory- and cognition-enhancing effects of racemic tianeptine and estianeptine seen in the NOR test are consistent with human clinical studies in which racemic tianeptine treatment improved cognition and memory in patients with Alzheimer’s disease and depression⁶ and in patients with bipolar disorder,⁷” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “We recently reported that estianeptine induces neuroplasticity in cell culture.² The new findings indicate that estianeptine also improves memory and cognition in the in vivo rat NOR test. We believe that together these findings support the development of tianeptine and estianeptine in psychiatric and neurodegenerative diseases. Tianeptine’s ability to restore atrophied neuronal connections in animals² suggests the potential to achieve durable outcomes.”

“The rat NOR test is an experimental tool to assess drug effects on memory and evaluate their potential as treatments for neurodegenerative conditions like Alzheimer’s disease,” said Gregory Sullivan, M.D., Chief Medical Officer of Tonix Pharmaceuticals. “Since the main initial clinical feature in Alzheimer’s disease is impairment in newly learned facts or memories, improving learning and memory are important properties of potential new therapeutics. The specific type of learning and recognition memory measured by the NOR is believed to be relevant to the neurocircuitry impaired in Alzheimer’s disease.”

Dr. Sullivan continued, “Our ongoing clinical studies in major depression on TNX-601 ER, which contains racemic tianeptine, are expected to inform and potentially accelerate the development of TNX-4300 which contains the single isomer, estianeptine. We believe that estianeptine bypasses the synapse and activates intracellular PPAR-β/δ and PPAR-γ targets. The finding that estianeptine is responsible for tianeptine’s ability to improve memory and cognition in the NOR test implicates PPAR-β/δ activation specifically as a molecular target. This finding is consistent with the impaired memory of mice lacking the PPAR-β/δ gene.”⁸

In depression, estianeptine is believed to act on PPAR-β/δ and PPAR-γ targets in the nucleus to enhance genetic transactivation involved in restoring hippocampal neuroplasticity and neurogenesis. These findings also have applicability to neurodegenerative diseases in which neuronal connections are atrophied.² The reported PPAR mechanism has potential relevance to why tianeptine is not associated with sexual dysfunction, weight gain or several other treatment-limiting toxicities associated with the antidepressants currently marketed in the U.S. for long-term use. However, tianeptine has other potential side effects that are described in its labeling outside the U.S. where it is marketed as a prescription drug.

Tonix owns worldwide rights to the novel salt, racemic tianeptine hemioxalate and to the proprietary extended-release formulation employed in TNX-601 ER that allows once daily dosing. TNX-601 ER is currently being studied in the Phase 2 UPLIFT trial, which is targeting enrollment of approximately 300 patients at about 30 U.S. clinical sites. Tonix has also filed patents claiming single (S)-isomer estianeptine, the active ingredient in TNX-4300, which is devoid of activity on the µ-opioid receptor. TNX-4300 is currently in preclinical development for depression, bipolar disorder, Alzheimer’s disease, and Parkinson’s disease.

Key experiments were performed by scientists at Tonix’s Research and Development Center (RDC) in Frederick, Maryland.

^*TNX-601 ER and TNX-4300 are investigational new drugs and are not approved for any indication. TNX-601 ER is being developed under an IND. TNX-4300 is at the pre-IND stage of development.

About Tianeptine

Racemic 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 tolerability profile from decades of use in these jurisdictions. Currently no tianeptine-containing product is approved in the U.S. and no extended-release once-daily tianeptine product is approved in any jurisdiction. 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.⁴ 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 is mechanistically distinct from traditional monoaminergic antidepressants marketed in the U.S. and contributes to its potential for clinical indications beyond depression and stress disorders. Tianeptine and its MC5 metabolite are also weak µ-opioid receptor (MOR) agonists that present a potential abuse liability if illicitly misused in large quantities.^3,9 In cases where tianeptine has been abused, the dose has been approximately 8-80 times the therapeutic dose in depression on a daily basis.⁹ 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 treated⁹ 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^11-15, 3-months,¹⁶ or 12-months¹⁷ of treatment. Estianeptine is believed to mimic naturally occurring polyunsaturated fatty acid ligands in low affinity interactions with PPAR-β/δ and PPAR-γ. Estianeptine’s activation of nuclear PPAR-β/δ and PPAR-γ receptors appears to be a more direct mechanism to achieve the goal of restoring neuronal connectivity than the active ingredients of current pharmacologic therapies for depression. Tianeptine’s proposed mechanism as a plastogen is consistent with its clinical effects in promoting cognition in depressed patients with Alzheimer’s disease⁵ and in patients with bipolar disorder.⁶ The PPAR-β/δ target is validated by prior work on agonists treating animal models of neurodegenerative and autoimmune diseases of the central nervous system.¹⁸ Alzheimer’s disease has been proposed to be a form of diabetes that affects the CNS, sometimes termed “type-III diabetes.”¹⁹The PPAR superfamily plays key roles in metabolic processes, and activation of PPAR-β/δ in brain by tianeptine shows promise to prevent the cognitive dysfunction associated with CNS insulin resistance. Tianeptine’s reported pro-cognitive and anxiolytic effects as well as its ability to attenuate the neuropathological effects of excessive stress responses suggest other potential uses including as a treatment for posttraumatic stress disorder (PTSD), as well as for preventing neurocognitive dysfunction associated with corticosteroid use.

About the Novel Object Recognition Test (NOR)

NOR is one of several cognitive tests that engage working memory and is considered a model for testing therapeutics or co-factors for Alzheimer’s disease.²⁰ The NOR task depends on the accurate comparison of novel information with recently stored memories. Among animal behavioral models for assessing cognitive functioning, the NOR test measures a specific form of recognition memory without assumptions about drug mechanism. The NOR is based on the spontaneous behavior of rodents without the need for external motivation, reward, or punishment. Impairments of NOR are seen in many animal models, including mice that overexpress the amyloid protein associated with Alzheimer’s disease.²¹ The NOR tests on tianeptine and estianeptine were performed by a third-party contract research organization. In the NOR test, rats were assessed for cognitive ability in a test apparatus comprising an open-field arena and were scored by an observer blind to treatments. The positive control for a drug effect was the acetylcholinesterase inhibitor medication galantamine, which is the active ingredient of Razadyne^®, approved by the U.S. Food and Drug administration as a treatment for Alzheimer’s disease. On Days 1 and 2, rats were allowed to freely explore the empty arena for a 10-minute habituation period. On Day 3, rats were administered saline, galantamine or test article (racemic tianeptine or estianeptine) and following the pretreatment time of 60 min, rats were then placed into the test arena in the presence of two identical objects. The time spent actively exploring the objects during a 3-minute training (T1) session was recorded. Each rat was returned to its home cage following training. After 48 hours, the rats were administered saline, galantamine or test article again, and, after 60 min, they were placed into the test arena in the presence of two objects: one familiar and one novel. The times spent exploring each object were recorded for 5 minutes in the testing session (T2). The outcome measure known as the Recognition Index was employed in these studies, defined as the ratio of the time spent exploring the novel object over the total time spent exploring both objects. These results are being prepared for presentation at a scientific meeting and for publication.

Social Anxiety Disorder Affects 15 Million U.S. Adults and is More Common Among Women than Men

CHATHAM, N.J., July 17, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP), a biopharmaceutical company, today announced that the first participant has been enrolled in a Phase 2 investigator-initiated, proof-of-concept study of TNX-1900 (potentiated intranasal oxytocin) for enhancing social safety learning in social anxiety disorder (SAD). Tonix entered into an agreement with the University of Washington to examine the potential role of TNX-1900 with Angela Fang, Ph.D., Assistant Professor, Department of Psychology, University of Washington as the principal investigator.

“We are excited to collaborate with the University of Washington and Dr. Fang on the development of TNX-1900 for social anxiety disorder,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “In the past decade, there has been an increase in studies examining oxytocin’s effects on social cognition and behavior in animals and humans due to translational discoveries showing that intranasal oxytocin appears to reach central nervous system targets¹. Specifically, evidence suggests that oxytocin may enhance the importance of social cues or have anti-anxiety properties^2,3. These studies have shown that intranasal oxytocin may hold therapeutic promise for psychiatric disorders involving social deficits^3-5. TNX-1900 is a proprietary formulation of oxytocin that contains magnesium, which Tonix has shown in animal models potentiates the action of oxytocin at oxytocin receptors and potentially improves the consistency of treatment by reducing paradoxical high-dose inhibition.”

“For psychiatric disorders characterized by severe social avoidance, such as social anxiety disorder, social learning has been disproportionately understudied despite its role in the acquisition of fear in models of anxiety,” said Dr. Fang. “Social anxiety disorder is a disabling psychiatric disorder. Past research has focused on the observational, or vicarious, acquisition of fears, but little is known about how social information (such as observing others experiencing safety) can promote safety learning. To address this issue, we will study the effects of vicarious extinction learning on the recovery of conditioned fear.”

The Phase 2 study is a randomized, double-blind, placebo-controlled trial, such that all participants will be randomized to receive a single dose of either TNX-1900 or matching placebo nasal spray. 100 subjects are planned to enroll: 50 with a primary diagnosis of SAD, and 50 demographically-matched healthy controls. The primary objective of the Phase 2 study is to examine the potential role of TNX-1900 in enhancing vicarious extinction learning in SAD, compared to healthy controls.

About Social Anxiety Disorder

Social anxiety disorder (SAD) is characterized by persistent fear of one or more social or performance situations in which the person is exposed to unfamiliar people or to possible scrutiny by others. The individual fears that he or she will act in a way (or show anxiety symptoms) that will be embarrassing and humiliating¹. SAD affects 15 million adults or 7.1% of the U.S. population, is more common among women than men, and typically begins around age 13^5-8. Individuals with SAD report experiencing symptoms for 16 years before seeking help⁹.

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 of 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 headache. Oxytocin when delivered via the nasal route, concentrates in the trigeminal system³ 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.⁴ Blocking CGRP release is a distinct mechanism compared with CGRP antagonist and anti-CGRP antibody drugs, which block the binding of CGRP to its receptor. With TNX-1900, the addition of magnesium to the oxytocin formulation enhances oxytocin receptor binding⁵ as well as its inhibitory effects on trigeminal neurons and resultant craniofacial analgesic effects, as demonstrated in animal models⁷. Intranasal oxytocin has been shown to be well tolerated in several clinical trials in both adults and children⁶. 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 antagonists such as anti-CGRP antibodies⁸. 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, binge eating disorder, craniofacial pain conditions, 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.

Preliminary Data Suggest that Oxytocin May Simultaneously Reduce Energy Intake and Increase Energy Expenditure

TNX-1900 (Intranasal Potentiated Oxytocin) May Serve as a Novel Neuroendocrine Weight-Loss Therapeutic for this Patient Population

CHATHAM, N.J., July 10, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced that the first participant was enrolled in the Phase 2 ‘POWER’ study of TNX-1900 (intranasal potentiated oxytocin) for the treatment of pediatric obesity at the Massachusetts General Hospital (MGH). The aim of the study is to investigate the efficacy and safety of TNX-1900 as a novel therapeutic agent to induce weight loss and improve indicators of cardiometabolic risk in adolescent patients with obesity. Tonix is providing active drug and placebo for the POWER study as part of a drug donation agreement with MGH. MGH is the sponsor of the National Institutes of Health-funded trial, being conducted under an investigator-initiated IND.

The 12-week double-blind, placebo-controlled trial has a target enrollment of 75 participants 12-18 years old with obesity.

“More than two-thirds of the U.S. population suffers from obesity or is overweight¹,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Available pharmacologic treatment options for weight loss in children are limited by safety/tolerability problems and failure to achieve sustained weight loss. It is essential to develop safe and effective therapeutic strategies for weight loss, particularly in adolescents, who are understudied while being at greatest risk for long-term comorbidities.”

Elizabeth A. Lawson, M.D., M.M.Sc., Director, Interdisciplinary Oxytocin Research Program in the Neuroendocrine Unit, Department of Medicine, Massachusetts General Hospital and principal investigator (along with Madhusmita Misra, MD, and Miriam Bredella, MD) of the study added, “Studies in animals have shown that oxytocin, a hypothalamic peptide hormone, simultaneously reduces food intake and increases energy expenditure, leading to weight loss. Intranasal oxytocin is well-tolerated and in our studies of adults, results in reduced caloric intake, increased fat burning, and improved insulin sensitivity. The goal of the double-blind POWER study is to assess whether intranasal administration of oxytocin will decrease weight as a consequence of decreased caloric intake and increased energy expenditure, and improve metabolic risk markers in adolescents with obesity.”

About the Phase 2 POWER Study

The Phase 2 POWER investigator-initiated study is a randomized, double blind, placebo-controlled study to evaluate the efficacy and safety of TNX-1900 for the treatment of pediatric obesity. The 12-week trial has a target enrollment of 75 participants 12-18 years old with obesity (BMI ≥95^th percentile for age and gender). Subjects will be randomized to receive TNX-1900 or placebo and will be studied at the Translational and Clinical Research Center at Massachusetts General Hospital. Subjects will self-administer TNX-1900 or placebo as two sprays total (one spray in each nostril) before meals and at bedtime for 12 weeks. The primary endpoint is 12-week change in body mass index standard deviation score (BMI-SDS) versus placebo.

About Pediatric Obesity²

Childhood obesity is a serious health problem in the United States, with approximately one in five children and adolescents affected. Many factors can contribute to excess weight gain including behavior, genetics and taking certain medications. Obesity-related conditions include high blood pressure, high cholesterol, type 2 diabetes, breathing disorders such as asthma and sleep apnea, polycystic ovary syndrome (in females), and joint pathology.

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 within the central nervous system (CNS). 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 headache. Oxytocin when delivered via the nasal route, concentrates in the trigeminal system³ 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.⁴ Blocking CGRP release is a distinct mechanism compared with CGRP antagonist and anti-CGRP antibody drugs, which block the binding of CGRP to its receptor. With TNX-1900, the addition of magnesium to the oxytocin formulation enhances oxytocin receptor binding⁵ as well as oxytocin’s inhibitory effects on trigeminal neurons and resultant craniofacial analgesic effects, as demonstrated in animal models⁷. Intranasal oxytocin has been shown to be well tolerated in several clinical trials in both adults and children⁶. Targeted nasal delivery results in low systemic exposure and lower risk of non-CNS, off-target effects, which could potentially occur with systemic CGRP antagonists such as anti-CGRP antibodies⁸. 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 patients greater control. In addition to chronic migraine, TNX-1900 will be developed for treatment of episodic migraine, binge eating disorder, and craniofacial pain conditions. Tonix also has a license with the University of Geneva for the use of TNX-1900 in the treatment of insulin resistance and related conditions.

“Examining the Working Definition for Long COVID” Included Presentations on Emerging Subgroups of Long COVID Patients Defined by Symptoms and Symptom Clusters

“Toward a Common Research Agenda in Infection-Associated Chronic Illnesses” Included Presentations on Long COVID Symptoms and Symptom Clusters in the Context of Recognized Infection-Associated Chronic Illnesses such as CFS/ME

Topline Results from Tonix’s Phase 2 PREVAIL Proof-of-Concept Study of TNX-102 SL for the Treatment of Fibromyalgia-Type Long COVID Expected Third Quarter 2023

CHATHAM, N.J., July 06, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a biopharmaceutical company, today announced comments relating to two recent meetings sponsored by the National Academies of Sciences, Engineering, and Medicine (National Academies) in Washington, D.C. and virtually, relating to the definition of Long COVID and to features of Long COVID that overlap with previously recognized infection-associated chronic conditions. The first meeting, “Examining the Working Definition for Long COVID”¹, took place on June 22 and 23, and the second, “Toward a Common Research Agenda in Infection-Associated Chronic Illnesses”² took place on June 29 and 30. Tonix Pharmaceuticals recognizes the potential benefits of defining subgroups of Long COVID patients based on their symptoms and recognizes the subgroup of Long COVID patients with symptoms that overlap with fibromyalgia. Tonix’s experience advancing TNX-102 SL (cyclobenzaprine HCl sublingual tablets)* as a treatment for fibromyalgia is the Company’s motivation for undertaking the development of TNX-102 SL for the management of Fibromyalgia-type Long COVID.

“Common symptoms of Long COVID, including multi-site pain, fatigue, unrefreshing sleep, and cognitive dysfunction, or ‘brain fog,’ are hallmarks of conditions like fibromyalgia and chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME),” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Defining subgroups of Long COVID patients that overlap with fibromyalgia and CFS/ME is expected to facilitate the development of new treatments.³ We are studying TNX-102 SL in the subgroup of Long COVID patients whose symptoms overlap with fibromyalgia, which we have termed ‘Fibromyalgia-type Long COVID.’ We expect topline data from this 63-patient proof-of-concept study in the third quarter of 2023. Fibromyalgia has been recognized by the U.S. Food and Drug Administration (FDA) with three approved medicines. Consequently, measuring daily pain is a validated endpoint for FDA registrational studies in fibromyalgia.”

“The recent identification of Long COVID subgroups in the National Institutes of Allergy and Infectious Diseases (NIAID)-sponsored RECOVER study⁴ was an important step,” said Herbert Harris, M.D., Ph.D., Executive Vice President and Head of Translational Medicine of Tonix Pharmaceuticals. “In their recent publication, “Development of a Definition of Postacute Sequelae of SARS-CoV-2 Infection” cluster analysis of the symptom frequencies in the RECOVER study (Researching COVID to Enhance Recovery (RECOVER) research program) identified four subgroups of Long COVID patients. Cluster #4 represented approximately one quarter of the population (28%) and reported the highest frequencies of pain (back pain (58%), joint pain (64%) or muscle pain (60%)), high frequencies of fatigue (94%) and ’Brain Fog,’ (94%) and a high level of impairment of Quality of Life. We believe Cluster #4 is a subgroup of Long COVID that overlaps with fibromyalgia. We also believe that Cluster #3, representing another approximately 29% of the RECOVER cohort, includes many patients with Fibromyalgia-type Long COVID because 100% of that group suffer from ‘Brain Fog’, 94% experience fatigue and approximately one third experience pain (back pain (32%), joint pain (36%) or muscle pain (34%)).”

Dr. Lederman continued, “Fibromyalgia can result from a variety of different stressors, in addition to infectious illnesses, including hormonal, metabolic, and psychological stressors.^3,5 It can be challenging to distinguish fibromyalgia and CFS/ME clinically, given the high level of symptom overlap between them. Each of these conditions is defined by a constellation of symptoms, and there is no widely recognized diagnostic laboratory test that distinguishes them.”

In April 2023, the Company completed enrollment of 63 participants in the PREVAIL study, a Phase 2 proof-of-concept study of TNX-102 SL for fibromyalgia-type Long COVID. Topline results from the PREVAIL trial are expected in the third quarter of 2023. In addition, the Company presented its analysis of a Fibromyalgia-type Long COVID subgroup from the TriNetX claims database at the BIO-sponsored Long COVID meeting in February 2023.^6,7 That study provided real-world evidence that the majority of Long COVID patients present with a constellation of symptoms that overlap with fibromyalgia and CFS/ME. These symptoms include fatigue, cognitive symptoms, and multi-site pain. Fibromyalgia-type Long COVID, like fibromyalgia and CFS/ME, appears to be both a subgroup of Long COVID and one of several chronic overlapping pain conditions that have in common the neurological process called central and peripheral sensitization, which is increasingly known by the term nociplastic pain.

Post-acute sequelae of COVID-19, or PASC is the formal name for a condition now widely known as Long COVID. Although most people recover from COVID-19 within weeks of the acute illness, a substantial portion develops a chronic syndrome called Long COVID. These individuals experience a constellation of disabling symptoms long past the time of recovery from acute COVID-19. Most Long COVID patients who have been studied appear to have cleared the SARS-CoV-2 infection from their systems. The symptoms of Long COVID can include fatigue, sleep disorders, multi-site pain, fevers, shortness of breath, cognitive impairment described as “brain fog” or memory disturbance, gastrointestinal symptoms, anxiety, and depression. Long COVID can persist for many months and can range in severity from mild to incapacitating. Several cohort studies have reported that the persistence of symptoms following SARS-CoV-2 infection occurs in approximately 10 – 30% of patients, depending on a variety of factors, including the strain of SARS-CoV-2 that was prevalent at the time of their infection.^7-9 Long COVID is typically associated with moderate or severe COVID-19, but can occur after mild COVID-19 or even after asymptomatic SARS-CoV-2 infection. Patients with Long COVID are sometimes referred to as “long-haulers.” Long COVID is a chronic disabling condition that is expected to result in a significant global health and economic burden.^8-11 In response to the urgent need for therapies that address Long COVID, Congress awarded $1.15 billion to the National Institutes of Health to study Long COVID in December 2020.¹² The U.S. Department of Health and Human Services National Research Action Plan on Long COVID¹³, released in August 2022, addresses the overlap of Long COVID with CFS/ME, which, like fibromyalgia, is one of the overlapping chronic pain syndromes with central and peripheral sensitization.¹⁴ A published survey¹⁵ found comparable pain, fatigue, and functional impairment between Long COVID, fibromyalgia, and CFS/ME. This symptom overlap between these conditions has suggested that altered neurologic function is one of the leading hypotheses to explain them.¹⁶ While the vaccines available in the U.S., through either FDA approval or under Emergency Use Authorization, have been shown to prevent acute COVID, their ability to prevent Long COVID is unknown. There is currently no approved drug for the treatment of Long COVID.
