Patients with chronic kidney disease (“CKD”) exhibit chronic systemic inflammation characterized by increased circulating levels of IL-1β, IL-6, and CRP.
This study demonstrated that CKD-induced IL-1β activates NLRP3 inflammasomes in the heart’s atria to trigger inflammation promoting the onset and progression of atrial fibrillation (“AF”).
ZyVersa is developing Inflammasome ASC Inhibitor IC 100, designed to inhibit inflammasomes and their associated extracellular ASC specks to attenuate propagation of IL-1β that triggers damaging inflammation and its spread to surrounding tissues.
WESTON, Fla., Sept. 22, 2023 (GLOBE NEWSWIRE) — ZyVersa Therapeutics, Inc. (Nasdaq: ZVSA, or “ZyVersa”), a clinical stage specialty biopharmaceutical company developing first-in-class drugs for treatment of inflammatory and renal diseases, announces publication of a paper in the peer-reviewed Journal of Clinical Investigation highlighting how inflammation in the kidneys can trigger inflammation in the heart.
In the paper titled, “Chronic kidney disease promotes atrial fibrillation via inflammasome pathway activation,” the authors conducted a study in mouse models of CKD and in-vitro studies with serum from CKD patients and atrial samples from CKD and other patients undergoing open heart surgery. Data from the research indicate that CKD creates a substrate (IL-1β) that activates NLRP3 inflammasomes in the heart’s atria triggering damaging inflammation associated with adverse atrial remodeling and dysfunction leading to AF.
The authors stated, “Together, these findings support the idea that CKD-induced systemic inflammatory factors activate the atrial NLRP3 inflammasome thereby promoting the onset of AF. This hypothesis is supported by the fact that genetic ablation of NLRP3 protected against abnormal atrial activation, atrial fibrosis and atrial enlargement induced by CKD.” To read the article, Click Here.
ZyVersa is developing Inflammasome ASC Inhibitor IC 100 to inhibit multiple inflammasomes, including NLRP3, and their associated ASC specs to attenuate release and perpetuation of circulating IL-1β to control inflammation in various inflammatory diseases.
“The research published in The Journal of Clinical Investigation reinforces the importance of attenuating extracellular propagation of IL-1β to minimize induction and perpetuation of inflammation in surrounding tissues,” commented Stephen C. Glover, ZyVersa’s Co-founder, Chairman, CEO, and President. “ZyVersa’s Inflammasome ASC inhibitor IC 100 is designed to inhibit formation of multiple types of inflammasomes to attenuate initiation of the inflammatory cascade, and to inhibit their associated ASC specks to reduce perpetuation of damaging inflammation.” To review a white paper summarizing the mechanism of action and preclinical data for IC 100, Click Here.
About Inflammasome ASC Inhibitor IC 100
IC 100 is a novel humanized IgG4 monoclonal antibody that inhibits the inflammasome adaptor protein ASC. IC 100 was designed to attenuate both initiation and perpetuation of the inflammatory response. It does so by binding to a specific region of the ASC component of multiple types of inflammasomes, including NLRP1, NLRP2, NLRP3, NLRC4, AIM2, Pyrin. Intracellularly, IC 100 binds to ASC monomers, inhibiting inflammasome formation, thereby blocking activation of IL-1β early in the inflammatory cascade. IC 100 also binds to ASC in ASC Specks, both intracellularly and extracellularly, further blocking activation of IL-1β and the perpetuation of the inflammatory response that is pathogenic in inflammatory diseases. Because active cytokines amplify adaptive immunity through various mechanisms, IC 100, by attenuating cytokine activation, also attenuates the adaptive immune response.

mTNX-1700 (mTFF2-MSA) suppresses tumor growth and increases survival rates in preclinical colorectal cancer models
mTNX-1700 shows single agent activity and additive effects in combination with anti-PD-1
mTNX-1700 targets myeloid-derived suppressor cells (MDSCs) in a novel mechanism to treat cancer
CHATHAM, N.J., Sept. 21, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP), a biopharmaceutical company with marketed products and a pipeline of development candidates, today announced a poster presentation showing research results for mTNX-1700 (murine trefoil factor family member 2- murine serum albumin, or mTFF2-MSA) at the Seventh International Cancer Immunotherapy Conference 2023 (CICON23): Translating Science into Survival, being held September 20-23, 2023, in Milan, Italy. The poster is available under the Scientific Presentations tab of the Tonix website at www.tonixpharma.com.
The poster presentation, titled, “mTFF2-MSA (mTNX-1700) Suppresses Tumor Growth and Increases Survival in Anti-PD-1 Treated CT26.WT Subcutaneous and CT26-Luciferase Orthotopic Syngeneic Colorectal Cancer Models by Targeting MDSCs in BALB/C Mice,” includes data demonstrating that the novel fusion protein, mTNX-1700 has single agent activity and can improve on the therapeutic effects of anti-PD-1 in treating syngeneic mouse models of advanced colorectal cancer. In two models, mTNX-1700 increases survival rates and suppresses tumor growth. Additive tumor growth suppression effects were observed when mTNX-1700 and anti-PD-1 were used in combination.
“mTNX-1700 is a novel fusion protein that has single agent activity and augments PD-1 blockade therapy in combination therapy in advanced and metastatic syngeneic mouse models of colorectal and gastric cancer,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Certain cancers are unresponsive to anti-PD-1 therapy. Despite the significance of PD-1 checkpoint blockade in treating many types of cancer, there’s a need to better understand why some cancers don’t respond and how to make them responsive. We believe these data show the potential of TNX-1700 in treating cancer both as a single agent and in combination with other immuno-oncology drugs, particularly anti-PD-1, and highlight how mTNX-1700 targets MDSCs as a novel mechanism to treat cancer.”
About Trefoil Factor Family Member 2 (TFF2)
Human TFF2 is a secreted protein, encoded by the TFF2 gene in humans, that is expressed in gastrointestinal mucosa where it functions to protect and repair mucosa. TFF2 is also expressed at low levels in splenic immune cells and is now appreciated to have intravascular roles in the spleen and in the tumor microenvironment. In gastric cancer, TFF2 is epigenetically silenced, and TFF2 is suggested to be protective against cancer development through several mechanisms. Tonix is developing TNX-1700 (rTFF2-HSA) for the treatment of gastric and colon cancers under a license from Columbia University. The inventor of the core technology at Columbia is Dr. Timothy Wang, who is an expert in the molecular mechanisms of carcinogenesis whose research has focused on the carcinogenic role of inflammation in modulating stem cell functions. Dr. Wang demonstrated that knocking out the mTFF2 gene in mice leads to faster tumor growth and that overexpression of TFF2 markedly suppresses tumor growth by curtailing the homing, differentiation, and expansion of MDSCs to allow activation of cancer-killing CD8+ T cells.1 He went on to show that a novel engineered form of recombinant murine TFF2 (mTFF2-CTP) had an extended half-life in vivo and was able to suppress MDSCs and tumor growth in an animal model of colorectal cancer. Later, he showed in gastric cancer models that suppressing MDSCs using chemotherapy enhances the effectiveness of anti-PD1 therapy and significantly reduces tumor growth.2 Dr. Wang proposed the concept of employing rTFF2 in combination with other therapies in cancer prevention and early treatment. Dr. Wang presented data at the American Association for Cancer Research (AACR) conference as a collaboration between Tonix and Columbia University in 2020 that includes data from a preclinical study which investigated the role of PD-L1 in colorectal tumorigenesis and evaluated the utility of targeting myeloid-derived suppressor cells (MDSCs) in combination with PD-1 blockade in mouse models of colorectal cancer. The data show that anti-PD-1 monotherapy was unable to evoke anti-tumor immunity in this model of colorectal cancer, but mTFF2-CTP augmented the efficacy of anti-PD-1 therapy. Anti-PD-1 in combination with TFF2-CTP showed greater anti-tumor activity in PD-L1-overexpressing mice.

Oxytocin receptors and CGRP are co-expressed on human trigeminal ganglia neurons and their expression is increased in inflammation
Human tissue data support the proposed mechanism of action of TNX-1900 in treating headache: oxytocin treatment blocks the release of CGRP
CHATHAM, N.J., Sept. 18, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a biopharmaceutical company with marketed products and a pipeline of development candidates, today announced that David C. Yeomans, Ph.D. presented data relevant to the proposed mechanism of TNX-1900 (intranasal potentiated oxytocin) in treating chronic migraine in a poster and an oral presentation at the 2023 International Headache Congress (IHC), being held September 14-17, 2023, in Seoul, South Korea. The poster and oral presentation titled, “Human trigeminal ganglia possess oxytocin receptors on CGRP positive neurons: expression increased by inflammation,” include research sponsored by and licensed to Tonix Pharmaceuticals. Professor Yeomans was a founder of Trigemina, which Tonix acquired, and he remains a consultant to Tonix. A copy of the poster is available under the Scientific Presentations tab of the Tonix Pharmaceuticals corporate website at www.tonixpharma.com.
The presentations show that oxytocin receptors are co-expressed with calcitonin gene-related peptide (CGRP) on human trigeminal ganglia neurons, which is similar to Professor Yeomans’ previous findings in animal trigeminal ganglia. The inflammatory cytokine IL-6 upregulated expression of oxytocin receptors on human trigeminal neurons, consistent with the previously observed impact of inflammation on the potency of oxytocin. In animals, oxytocin has been shown to functionally inhibit the excitability of trigeminal neurons, which is consistent with oxytocin inhibiting the release of CGRP at trigeminal nerve terminals.1
“In animal studies, oxytocin has been shown to inhibit trigeminal neurons which we believe relates to its mechanism in preventing migraines,”1 said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “The data presented at 2023 IHC by Professor Yeomans shows that oxytocin receptors are present on human trigeminal ganglia neurons, and that these same neurons express CGRP, a key peptide in the pathogenesis of migraine. These data support the proposed mechanism of TNX-1900, which we believe inhibits the release of CGRP from trigeminal neurons that otherwise would trigger a cascade leading to migraine.”
“Similar to animals, human trigeminal ganglia neurons express oxytocin receptors and also co-express CGRP,” said Professor Yeomans. “In addition, the inflammatory mediator IL-6 induces robust upregulation of oxytocin receptors on human trigeminal ganglia neurons. In the presence of inflammation, which is persistently present in chronic migraine, there is a robust increase in the expression of both oxytocin receptors and CGRP in human trigeminal neurons.”
In February 2023, Tonix initiated enrollment in the Phase 2 ‘PREVENTION’ study of TNX-1900 for the prevention of migraine headache in chronic migraineurs. Topline results from the study are expected in the fourth quarter of 2023. In addition, TNX-1900 is also being evaluated in investigator-initiated Phase 2 trials in adolescent obesity (initiated July 2023), binge eating disorder and social anxiety disorder.

Activation of multiple inflammasome pathways contributes to pathological inflammation in neurodegenerative (“CNS”) diseases, such as amyotrophic lateral sclerosis (“ALS”)
This study showed that NLRP3 inhibition alone was inadequate to address CNS inflammation in a mouse model of ALS
ZyVersa is developing Inflammasome ASC Inhibitor IC 100, designed to inhibit up to 12 different inflammasomes (including NLRP3 inflammasomes) and their associated ASC specks to control damaging inflammation in CNS and non-CNS inflammatory diseases
WESTON, Fla., Sept. 12, 2023 (GLOBE NEWSWIRE) — ZyVersa Therapeutics, Inc. (Nasdaq: ZVSA, or “ZyVersa”), a clinical stage specialty biopharmaceutical company developing first-in-class drugs for treatment of inflammatory and renal diseases, announces publication of a paper in the peer-reviewed journal, Frontiers in Immunology, highlighting potential limitations of NLRP3 inhibition in attenuating CNS Inflammation associated with activation of multiple inflammasome pathways. This paper supports ZyVersa’s rationale for targeting inflammasome ASC with IC 100 to inhibit multiple inflammasome pathways, not just NLRP3, to control inflammation in various inflammatory diseases.
In the paper titled, “Divergent functional outcomes of NLRP3 blockade downstream of multi-inflammasome activation: therapeutic implications for ALS,” the authors conducted studies in various human cell lines and in an animal model of ALS. Data demonstrate that NLRP3 inhibition alone is insufficient to attenuate proinflammatory cytokine release and inflammatory cell death associated with activation of multiple inflammasome pathways. Likewise, NLRP3 inhibition alone did not ameliorate spinal cord inflammation in an ALS model.
The authors stated, “we hypothesize that strategies that impact multiple inflammasome pathways may hold more promise in CNS disorders like ALS where multiple inflammasomes are dysregulated.” To read the article Click Here.
“The research published in Frontiers in Immunology reinforces the need to inhibit more than the NLRP3 inflammasome pathway to control inflammation associated with activation of multiple inflammasomes,” commented Stephen C. Glover, ZyVersa’s Co-founder, Chairman, CEO and President. “ZyVersa’s Inflammasome ASC inhibitor IC 100 is designed to inhibit formation of multiple types of inflammasomes to attenuate initiation of the inflammatory cascade, and to inhibit ASC specks to attenuate perpetuation of damaging inflammation.” To review a white paper summarizing the mechanism of action and preclinical data for IC 100, Click Here.
About Inflammasome ASC Inhibitor IC 100
IC 100 is a novel humanized IgG4 monoclonal antibody that inhibits the inflammasome adaptor protein ASC. IC 100 was designed to attenuate both initiation and perpetuation of the inflammatory response. It does so by binding to a specific region of the ASC component of multiple types of inflammasomes, including NLRP1, NLRP2, NLRP3, NLRC4, AIM2, Pyrin. Intracellularly, IC 100 binds to ASC monomers, inhibiting inflammasome formation, thereby blocking activation of IL-1β early in the inflammatory cascade. IC 100 also binds to ASC in ASC Specks, both intracellularly and extracellularly, further blocking activation of IL-1β and the perpetuation of the inflammatory response that is pathogenic in inflammatory diseases. Because active cytokines amplify adaptive immunity through various mechanisms, IC 100, by attenuating cytokine activation, also attenuates the adaptive immune response.

Neumora and RayzeBio, two emerging small cap biotech companies, filed on Monday for initial public offerings (IPOs) on the Nasdaq exchange. The firms are seeking to raise over $200 million each through their stock market debuts.
Neumora, a neuroscience startup, plans to offer 14.7 million shares priced between $16-18 to raise around $227 million under the ticker symbol NMRA. RayzeBio, a radiopharmaceuticals developer, aims to raise about $206 million by offering 13.2 million shares priced at $16-18 per share and trading as RYZB.
As small cap biotechs in earlier stages of development, Neumora and RayzeBio are seen as riskier investments than large cap pharmaceutical firms. However, both companies have drugs in late-stage pipelines and will use their IPO proceeds to fund Phase 3 clinical trials.
Neumora’s lead candidate is a depression drug called navacaprant, while RayzeBio is focused on advancing its radioligand therapy RYZ101 for rare tumors through Phase 3. Their ability to progress their pipelines with capital from the IPOs could improve their growth prospects as public companies.
The biotech IPO market has been tepid so far in 2023, making the environment challenging for small cap biotech listings. But Neumora and RayzeBio’s offerings may provide a test for investor appetite for new issues in the sector. Strong demand could reopen the IPO window for other young biotechs seeking to raise growth capital this year.

Onconova’s product candidate rigosertib is being studied in multiple investigator-sponsored studies, including a dose-escalation and expansion Phase 1/2a study of oral rigosertib in combination with nivolumab in patients with KRAS+ non-small cell lung cancer (NCT04263090), a Phase 2 program evaluating oral or IV rigosertib monotherapy in advanced squamous cell carcinoma complicating recessive dystrophic epidermolysis bullosa (RDEB-associated SCC (NCT03786237, NCT04177498), and a Phase 2 trial evaluating rigosertib in combination with pembrolizumab in patients with metastatic melanoma (NCT05764395).
Tosymra Nasal Spray 10 mg is a Proprietary Acute Migraine Treatment Approved Under the 505(b)2 Pathway Based on Bioequivalence to Imitrex (sumatriptan) Injection 4 mg
GlaxoSmithKline Recently Notified FDA that it will Discontinue Imitrex Nasal Spray 5 mg and 20 mg Products after January 2024
CHATHAM, N.J., Sept. 06, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a biopharmaceutical company with marketed products and a pipeline of development candidates, today announced that it is committed to meeting potential increased demand for Tosymra® (sumatriptan) nasal spray 10 mg after GlaxoSmithKline’s (GSK) planned discontinuation of Imitrex (sumatriptan) nasal spray 5 mg and 20 mg products after January, 2024.
On August 8, 2023, GSK informed the U.S. Food and Drug Administration (FDA) of its plan to discontinue Imitrex nasal spray 5 mg and 20 mg doses after January 31, 2024. The notification is posted on the FDA Drug Shortages website.1 Tonix is preparing for potential increased demand for Tosymra (sumatriptan nasal spray) 10 mg to help avoid possible drug shortages for patients who suffer from migraines. Tosymra nasal spray is approved on the basis of bioequivalence to Imitrex injection 4 mg.
Drug shortages have presented an ongoing challenge for the U.S. healthcare system, reaching near-record levels2 in recent months, causing treatment delays and rationing. Tonix is ready to step in to alleviate potential shortages in sumatriptan, a widely used treatment option for acute migraine.
“In response to FDA outreach, we have confirmed our commitment to meet potential increased demand for sumatriptan nasal spray from patients who suffer from migraines,” said Seth Lederman, M.D., President and Chief Executive Officer of Tonix. “While Tosymra nasal spray and Imitrex nasal spray are not substitutable at the pharmacy, we plan to alert providers to the possibility of prescribing Tosymra for patients who may benefit from a nasal spray formulation of sumatriptan.”
The American Headache Society Consensus Statement on migraine treatments recommends that “a non-oral formulation should be used in patients whose attacks are associated with severe nausea or vomiting, who do not respond well to traditional oral treatments, or who have trouble swallowing orally administered medications.”3 Approximately 73% of migraine patients have been reported to experience nausea with or without vomiting during their attacks.4
“Intranasal sumatriptan is an important therapy for those who suffer from migraines. We believe Tosymra is differentiated from other intranasal formulations of sumatriptan, which are generic equivalents to Imitrex nasal spray because of its proprietary Intravail® absorption enhancer technology,” said James Hunter, Executive Vice President of Commercial Operations at Tonix Pharmaceuticals and President of Tonix Medicines. “Intravail technology helps the medication absorb into the bloodstream so it can work quickly, providing migraine pain relief in as little as 10 minutes for some patients.”5,6,7
About Migraine
Nearly 40 million people in the United States suffer from migraine8 and it has been recognized as the second leading cause of disability in the world.9 Migraine is characterized by debilitating attacks lasting four to 72 hours with multiple symptoms, including pulsating headaches of moderate to severe pain intensity often associated with nausea or vomiting, and/or sensitivity to sound (phonophobia) and sensitivity to light (photophobia).
Tonix Pharmaceuticals Holding Corp.*
Tonix is a biopharmaceutical company focused on commercializing, developing, discovering and licensing therapeutics to treat and prevent human disease and alleviate suffering. Tonix Medicines, our commercial subsidiary, markets Zembrace® SymTouch® (sumatriptan injection) 3 mg and Tosymra® (sumatriptan nasal spray) 10 mg under a transition services agreement with Upsher-Smith Laboratories, LLC from whom the products were acquired on June 30, 2023. Zembrace SymTouch and Tosymra are each indicated for the treatment of acute migraine with or without aura in adults. Tonix’s development portfolio is composed of central nervous system (CNS), rare disease, immunology and infectious disease product candidates. Tonix’s CNS development portfolio includes both small molecules and biologics to treat pain, neurologic, psychiatric and addiction conditions. Tonix’s lead development CNS candidate, TNX-102 SL (cyclobenzaprine HCl sublingual tablet), is in mid-Phase 3 development for the management of fibromyalgia, having completed enrollment of a potentially confirmatory Phase 3 study in the third quarter of 2023, with topline data expected in the fourth quarter of 2023. TNX-102 SL is also being developed to treat fibromyalgia-type Long COVID, a chronic post-acute COVID-19 condition. Enrollment in a Phase 2 proof-of-concept study has been completed, and topline results were reported in the third quarter of 2023. TNX-601 ER (tianeptine hemioxalate extended-release tablets) is a once-daily oral formulation being developed as a treatment for major depressive disorder (MDD), that completed enrollment in a Phase 2 proof-of-concept study in the third quarter of 2023, with topline results expected in the fourth quarter of 2023. TNX-4300 (estianeptine) is a single isomer version of TNX-601, small molecule oral therapeutic in preclinical development to treat MDD, Alzheimer’s disease and Parkinson’s disease. Relative to tianeptine, estianeptine lacks activity on the µ-opioid receptor while maintaining activity in the rat Novel Object Recognition test in vivo and the ability to activate PPAR-β/δ and neuroplasticity in tissue culture. TNX-1900 (intranasal potentiated oxytocin), is in development for preventing headaches in chronic migraine, and has completed enrollment in a Phase 2 proof-of-concept study with topline data expected in the fourth quarter of 2023. TNX-1900 is also being studied in binge eating disorder, pediatric obesity and social anxiety disorder by academic collaborators under investigator-initiated INDs. TNX-1300 (cocaine esterase) is a biologic designed to treat cocaine intoxication and has been granted Breakthrough Therapy designation by the FDA. A Phase 2 study of TNX-1300 is expected to be initiated in the third quarter of 2023. Tonix’s rare disease development portfolio includes TNX-2900 (intranasal potentiated oxytocin) for the treatment of Prader-Willi syndrome. TNX-2900 has been granted Orphan Drug designation by the FDA. Tonix’s immunology development portfolio includes biologics to address organ transplant rejection, autoimmunity and cancer, including TNX-1500, which is a humanized monoclonal antibody targeting CD40-ligand (CD40L or CD154) being developed for the prevention of allograft rejection and for the treatment of autoimmune diseases. A Phase 1 study of TNX-1500 was initiated in the third quarter of 2023. Tonix’s infectious disease pipeline includes TNX-801, a vaccine in development to prevent smallpox and mpox. TNX-801 also serves as the live virus vaccine platform or recombinant pox vaccine platform for other infectious diseases. The infectious disease development portfolio also includes TNX-3900 and TNX-4000, which are classes of broad-spectrum small molecule oral antivirals.

TNX-102 SL showed a robust effect size of 0.5 in improving fatigue and showed consistent activity across secondary measures of sleep quality, cognitive function, disability and Patient Global Impression of Change, but did not meet the primary endpoint of multi-site pain reduction at week 14
Findings fulfill the objectives of this proof-of-concept study, supporting the decision to advance the program based on a proposed primary endpoint using the PROMIS Fatigue scale
Tonix plans to meet with FDA to discuss a path to registration; fatigue is the signature symptom of Long COVID and the principal symptom overlapping with CFS/ME and fibromyalgia syndromes
CHATHAM, N.J., Sept. 05, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a biopharmaceutical company with marketed products and a pipeline of development candidates, today announced topline results from the Phase 2 proof-of-concept PREVAIL study of TNX-102 SL 5.6 mg for the management of fibromyalgia-type Long COVID. TNX-102 SL treatment showed a robust effect size (ES) in improving fatigue and showed consistent activity trending to improvements across the secondary endpoints of sleep quality, cognitive function, disability and patient global impression of change (PGIC). TNX-102 SL trended towards improvement but did not achieve the pre-specified primary endpoint of improving Long COVID pain intensity scores at Week 14. The proposed mechanism of TNX-102 SL is improving sleep quality, which NIH recently announced is a target of future RECOVER clinical trials in Long COVID, a National Institute of Health (NIH) research program designed to understand, treat, and prevent long COVID.1,2 There is currently no approved drug for the treatment of Long COVID.
PREVAIL was a randomized, double-blind, placebo-controlled, multi-site proof-of-concept study of 63 patients with laboratory-documented COVID-19 illness preceding Long COVID. PREVAIL was designed and conducted to guide the design of registrational studies of TNX-102 SL in fibromyalgia-type Long COVID. TNX-102 SL was generally well tolerated with an adverse event (AE) profile comparable to prior studies with TNX-102 SL. AE-related discontinuations were similar in drug and placebo arms. No new safety signals were observed.
“The robust activity of TNX-102 SL on the PROMIS Fatigue scale3-5 (ES=0.5, Figure 4) is important because patients and experts view fatigue as the signature symptom of Long COVID and it has been identified as the dominant symptom contributing to disability,”6 said Dr. Seth Lederman, President and CEO of Tonix Pharmaceuticals. “In addition, TNX-102 SL showed consistent trends toward improvement in sleep quality, cognitive function, disability and the PGIC responder rate for TNX-102 SL compared to placebo (Figure 5) at week 14 (34.4% vs. 16.1%, difference=18.2%). Together, these findings fulfill the objectives of this proof-of-concept study in supporting the decision to advance the program based on a proposed primary endpoint using the PROMIS Fatigue scale.”
The Company intends to request an End-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) to discuss a potential Phase 3 program based on a proposed primary outcome measure using the PROMIS Fatigue scale. The meeting is expected to take place in the first quarter of 2024. Fatigue is the symptom of Long COVID that principally overlaps with chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) and fibromyalgia. In the NIH funded RECOVER study analysis, fatigue was the top featured symptom and is common in each of the four clusters.7
“The data from PREVAIL reinforce our belief in TNX-102 SL as a potential bedtime medicine for the management of fibromyalgia-type Long COVID,” said Gregory Sullivan, M.D., Chief Medical Officer of Tonix Pharmaceuticals. “We believe the PREVAIL trial results will help guide the next phase of development for TNX-102 SL, supporting the design of a potential registrational trial for fibromyalgia-type Long COVID based on PROMIS fatigue as a primary endpoint, pending review and feedback from the FDA. In both of our prior Phase 3 studies of TNX-102 SL 5.6 mg in fibromyalgia, we observed numerical improvement in the PROMIS fatigue score (in RELIEF p=0.007 MMRM8 and in RALLY p=0.007 MMRM9).”
Dr. Sullivan continued, “Although the validity of PROMIS Fatigue is not yet established in Long COVID, we believe the results of PREVAIL, together with extensive data from studies in other chronic conditions3-5 – including Tonix’s studies in fibromyalgia – make PROMIS Fatigue a solid candidate for the primary endpoint of future Long COVID registrational studies. We look forward to an anticipated End-of-Phase 2 meeting with the FDA to discuss these data and expect to present full data from PREVAIL in a peer-reviewed format and at upcoming medical conferences. Together, we believe these findings support the recognition of fibromyalgia-type Long COVID as a clinically meaningful subgroup of Long COVID patients and underscore the potential of TNX-102 SL as a once daily, oral therapy for this debilitating condition. We are grateful to the patients and their families and supporters, who participated in this study.”
Key Phase 2 PREVAIL Study Results
In the study, 63 subjects were enrolled and randomized 1:1 across approximately 30 U.S. sites to receive either TNX-102 SL or placebo daily at bedtime for 14 weeks. Subjects started with TNX-102 SL 2.8 mg tablet or one placebo tablet for the first 2 weeks and then increased to TNX-102 SL 5.6 mg (2 x 2.8 mg tablets) or two placebo tablets for the remaining 12 weeks of the treatment period. The percentage of subjects completing the study was 81.3% in the TNX-102 SL group and 80.6% in the placebo group. Demographics and baseline characteristics are shown in Table 1.

Primary endpoint
Given the lack of Long COVID treatments and the size of the current proof-of-concept study, an ES ≥ 0.2 was the pre-specified threshold for declaring the primary endpoint positive. The study trended towards a benefit but did not achieve statistical significance on the primary efficacy endpoint of change from baseline in the diary numerical rating scale (NRS) weekly average of daily self-reported worst Long COVID pain intensity scores for TNX-102 SL at the Week 14 endpoint versus placebo (effect size (ES) = 0.08, Figure 1.)
Secondary endpoints
The change from baseline to the Week 14 endpoint for the daily sleep quality diary, PROMIS Sleep Disturbance, PROMIS Fatigue, PROMIS Cognitive function, the Insomnia Severity Index (ISI) and Sheehan Disability Scale showed numerical improvements (MMRM, ES ≥ 0.2): sleep diary (MMRM, ES =0.23, Figure 2.), PROMIS sleep Disturbance (MMRM, ES=0.32, Figure 3.), PROMIS fatigue (MMRM, ES=0.50, Figure 4.), PROMIS Cognitive Function – Abilities, (MMRM, ES=0.21), the ISI (ANCOVA, ES=0.24) and the Sheehan Disability Scale (ANCOVA, ES=0.26). Moreover, robust activity was observed in the PGIC responder (very much improved or much improved) rate for TNX-102 SL compared to placebo (Figure 5): week 6 (31.3% vs. 9.7%, difference=21.6%), week 10 (28.1% vs. 12.9%, difference=15.2%), week 14 (34.4% vs. 16.1%, difference=18.2%).
Safety profile
TNX-102 SL demonstrated a favorable safety and tolerability profile over 14 weeks of treatment with no new safety signals. The most common adverse events are shown in Table 2. Participants with at least one treatment-emergent adverse event (TEAE) were at a rate of 56.3% on TNX-102 SL and 38.7% on placebo. In the TNX-102 SL group, 6.3% discontinued due to TEAE compared to 9.7% on placebo. Only one TEAE in the study was rated as severe, gastritis in a participant in the TNX-102 SL group. There were no serious adverse events (SAEs) in the study.

About the Phase 2 PREVAIL Study The Phase 2 PREVAIL proof-of-concept study was 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 laboratory-documented post-acute sequelae of SARS-CoV-2 infection (PASC). The trial was conducted at approximately 30 sites in the U.S. The primary efficacy endpoint is 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.

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. The U.S. Department of Health and Human Services (HHS) recently estimated that 7.7 million to 23 million Americans have developed Long COVID and announced the formation of the “Office of Long COVID Research and Practice” to lead the Long COVID response and coordinate efforts across the federal government. 10 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.11 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.11 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 2020.16 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.
About 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 CFS/ME. Defining subgroups of Long COVID patients that overlap with fibromyalgia and CFS/ME is expected to facilitate the development of new treatments.20 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.’ TNX-102 SL is in phase 3 development for the management of fibromyalgia.8,21 Fibromyalgia has been recognized by the U.S. Food and Drug Administration (FDA) with three approved medicines. The recent identification of Long COVID subgroups in the National Institutes of Allergy and Infectious Diseases (NIAID)-sponsored RECOVER study7 was an important step. In their recent publication7 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%)). Fibromyalgia can result from a variety of different stressors, in addition to infectious illnesses, including hormonal, metabolic, and psychological stressors.23,24 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. We presented an analysis of a Fibromyalgia-type Long COVID subgroup from the TriNetX claims database at the BIO-sponsored Long COVID meeting in February 2023.21 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.
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.

Tonix Medicines, our commercial subsidiary, markets Zembrace® SymTouch® (sumatriptan injection) 3 mg and Tosymra® (sumatriptan nasal spray) 10 mg under a transition services agreement with Upsher-Smith Laboratories, LLC from whom the products were acquired on June 30, 2023. Zembrace SymTouch and Tosymra are each indicated for the treatment of acute migraine with or without aura in adults. Tonix’s development portfolio is composed of central nervous system (CNS), rare disease, immunology and infectious disease product candidates. Tonix’s CNS development portfolio includes both small molecules and biologics to treat pain, neurologic, psychiatric and addiction conditions. Tonix’s lead development CNS candidate, TNX-102 SL (cyclobenzaprine HCl sublingual tablet), is in mid-Phase 3 development for the management of fibromyalgia, having completed enrollment of a potentially confirmatory Phase 3 study in the third quarter of 2023, with topline data expected in the fourth quarter of 2023. TNX-102 SL is also being developed to treat fibromyalgia-type Long COVID, a chronic post-acute COVID-19 condition. Topline results from a proof-of-concept Phase 2 study were reported in the third quarter of 2023. TNX-601 ER (tianeptine hemioxalate extended-release tablets) is a once-daily oral formulation being developed as a treatment for major depressive disorder (MDD), that completed enrollment in a Phase 2 proof-of-concept study in the third quarter of 2023, with topline results expected in the fourth quarter of 2023. TNX-4300 (estianeptine) is a single isomer version of TNX-601, small molecule oral therapeutic in preclinical development to treat MDD, Alzheimer’s disease and Parkinson’s disease. Relative to tianeptine, estianeptine lacks activity on the µ-opioid receptor while maintaining activity in the rat Novel Object Recognition test in vivo and the ability to activate PPAR-β/δ and neuroplasticity in tissue culture. TNX-1900 (intranasal potentiated oxytocin), is in development for preventing headaches in chronic migraine, and has completed enrollment in a Phase 2 proof-of-concept study with topline data expected in the fourth quarter of 2023.

SECOND QUARTER FINANCIAL RESULTS
Since its inception in 2014 through June 30, 2023, ZyVersa has not generated any revenue and has incurred significant operating losses and negative cash flows from its operations. Based on our current operating plan, we expect our cash of $0.2 million as of June 30, 2023, will only be sufficient to fund our operating expenses and capital expenditure requirements on a month-to-month basis. ZyVersa will need additional financing to support its continuing operations. ZyVersa will seek to fund its operations through public or private equity or debt financings or other sources, which may include government grants and collaborations with third parties.
Research and development expenses were $1.2 million for the three months ended June 30, 2023, an increase of $0.5 million or 69.7% from the three months ended June 30, 2022. The increase is primarily attributable to an increase of $0.5 million in the costs of manufacturing of IC 100.
General and administrative expenses were $3.9 million for the three months ended June 30, 2023, an increase of $2.8 million or 237.5% from the three months ended June 30, 2022. The increase is primarily attributable to $1.2 million of common stock granted to certain stockholders in exchange for increasing the duration of their lockup period for certain common stockholdings, $0.5 million in professional fees associated with being a public company, a $0.5 million increase in marketing costs for investor and public relations, $0.4 million in director and officer insurance, and $0.2 million for bonus accruals.
Pre-tax losses were $86.3 million for the three months ended June 30, 2023, an increase of $84.3 million compared to a pre-tax loss of approximately $2.0 million, for the three months ended June 30, 2022. The higher net loss reported for the three months ended June 30, 2023 is primarily due to the impairment of in-process research and development and impairment of goodwill of $69.3 million and $11.9 million, respectively, compared to none for the three months ended June 30, 2022. The impairment is a result of the decline in ZyVersa’s market capitalization as of June 30, 2023.
Net losses were $78.5 million for the three months ended June 30, 2023, an increase of $76.5 million compared to a net loss of approximately $2.0 million for the three months ended June 30, 2022. A deferred tax benefit of $7.8 million for the three months ended June 30, 2023, compared to no tax benefit or expense during the three months ended June 30, 2022, resulted from the impairment of the in-process research and development.

Phase 1/2 Clinical Trial of TNX-801 for the Prevention of Mpox and Smallpox to Commence Following Submission of an IND
TNX-801 is Based on a Proprietary Live Virus Vaccine Platform Designed to Stimulate Durable T-Cell Immunity
TNX-801 Vaccination Protected Animals from a Lethal Challenge with Monkeypox in Preclinical Testing
CHATHAM, N.J., Aug. 21, 2023 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a biopharmaceutical company with marketed products and a pipeline of development candidates, today announced that it received the official written response from a Type B pre-Investigational New Drug Application (IND) meeting with the U.S. Food and Drug Administration (FDA) to develop TNX-8011 (recombinant horsepox virus, live vaccine) as a potential vaccine to protect against mpox disease (formerly known as monkeypox) and smallpox. Tonix believes the FDA feedback provides a path to agreement on the design of a Phase 1/2 study and the overall clinical development plan. The Phase 1/2 clinical trial will assess the safety, tolerability, and immunogenicity of TNX-801, following the submission and clearance of an IND.
“The FDA’s response to the pre-IND meeting marks an important milestone in the development of TNX-801 since we have FDA concurrence on the proposed manufacturing, toxicology studies, and the Phase 1/2 clinical design,” said Seth Lederman, M.D., President and Chief Executive Officer of Tonix. “TNX-801 is believed to be closely related to Edward Jenner’s original smallpox vaccine.2-10 Jenner’s live virus smallpox vaccine – the first vaccine – remains one of the most effective vaccines in history, since it typically provided lifetime immunity with a single dose, prevented forward transmission of the smallpox virus, and ultimately eradicated the disease. TNX-801 has an attenuated phenotype relative to modern vaccinia viruses, which comprise a group of vaccine viruses that evolved from Jenner’s vaccine during passage in man and animals for over 100 years. When live virus vaccinia vaccination was routinely practiced in Africa, mpox was kept out of the human population.”2,11
TNX-801 is a live replicating attenuated vaccine based on horsepox that is believed to protect against smallpox and mpox, primarily by eliciting a T-cell response evidenced by the “take”. The “take” is a functional measure of protective T-cell immunity validated by the eradication of smallpox. TNX-801 is administered with a single dose, can be readily scaled up for manufacturing using proven technology and can be distributed and stored without requiring a costly and cumbersome ultra-cold supply chain. Live replicating vaccines have the potential to induce durable T-cell immunity, prevent serious illness after infection and block forward transmission. Tonix reported positive preclinical efficacy data, demonstrating that TNX-801 vaccination protected non-human primates against lethal challenge with mpox.12
“More than 30,000 people have contracted mpox in the U.S. so far during the 2022-23 epidemic,”13 said Dr. Zeil Rosenberg, Executive Vice President, Medical at Tonix. “The recent cluster of mpox in Chicago revealed breakthrough cases of mpox in individuals who had been vaccinated with the currently authorized non-replicating vaccine, which is administered in two doses.14 In contrast, TNX-801 is delivered intradermally with only one dose and therefore may achieve higher rates of community protection by eliminating drop-out between doses and limiting forward transmission. Moreover, relying on only one approved mpox vaccine at present is a risk for the global supply chain that has already led to insufficient availability of vaccine to meet global health needs, especially in Africa.”
Dr. Rosenberg added, “We believe TNX-801 could make a global impact on mpox and the risk of smallpox because of its potential durable T-cell immune response, the ability to manufacture at scale, to use a lower dose than non-replicating vaccines. The current formulation is a frozen liquid, but we believe that future lyophilized versions can be stored and shipped at standard refrigeration. Moreover, we believe the low dose of TNX-801 makes this technology amenable for future implementation in microneedle delivery systems.”
Dr. Lederman concluded, “In addition to its potential use as a vaccine, TNX-801 also has the potential as a viral vector platform, for which versions can be developed to protect against a host of infectious diseases beyond smallpox and mpox, including COVID-19. In light of the recent resurgence in COVID cases across the country with the new EG.5 “Eris” variant, we believe that the horsepox recombinant pox virus platform may provide next generation vaccines to prevent future outbreaks.”
About TNX-801* TNX-801 is a live virus vaccine based on horsepox2,11. Horsepox and vaccinia are closely related orthopoxviruses that are believed to share a common ancestor. TNX-801 is believed to be more closely related to Jenner’s vaccinia vaccine than modern vaccinia vaccines, which appear to have evolved by deletions and mutations to a phenotype of larger plaque size in tissue culture and greater virulence in mice. Molecular analysis shows that horsepox is closer than modern vaccinia vaccines in DNA sequence to the vaccine discovered and disseminated by Dr. Edward Jenner.2-10 Vaccine genome researchers have recently shown the contemporaneous use of horsepox and horsepox-related viruses in the United States as smallpox vaccines in the 1860’s9,10. Additionally they found a remarkable degree of identity with the circa 1860 U.S. smallpox vaccine VK05 and the 1976 Mongolian horsepox isolate called MNR-76, upon which Tonix’s TNX-801 is based.3,5 These recent discoveries are further steps in establishing that what is called ’horsepox‘ today was used to vaccinate against smallpox in the 19th century. Dr. Edward Jenner invented vaccination in 1798 and the procedure was called “vaccination” because the inoculum material was initially obtained from lesions on the udders of cows affected by a mild disease known as cowpox2. ‘Cow’ is ‘vacca’ in Latin. However, Dr. Jenner suspected that cowpox originated from horsepox.2 Subsequently, Dr. Jenner and others immunized against smallpox using material directly obtained from horses. The use of vaccines from horses was sometimes called ‘equination’ from the Latin ‘equus’ which means ‘horse’. Equination and vaccination were practiced side-by-side in Europe6. The small plaque size in culture of TNX-801 appears identical to the U.S. Centers for Disease Control publication of the natural isolate12. Relative to vaccinia, horsepox has substantially decreased virulence in mice3. Tonix’s TNX-801 vaccine candidate is administered intradermally. The major cutaneous reaction or “take” to vaccinia vaccine was described by Dr. Edward Jenner in 1796 and has been used since then as a biomarker for protective immunity to smallpox, including in the World Health Organization’s (WHO) accelerated smallpox eradication program that successfully eradicated smallpox in the 1960’s.
TNX-801 is in the pre-IND stage and has not been approved for any indication.
