TNXP

Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced financial results for the fourth quarter and full year ended December 31, 2022, and provided an overview of recent operational highlights.

“Our clinical activity is at a high point in the Company’s history, and we believe it is setting the stage for a year of significant accomplishments across an expanded portfolio of novel pharmaceutical candidates designed to serve major unmet medical needs,” said Seth Lederman, M.D., Chief Executive Officer of Tonix.

“We are pleased with the progress of our current Phase 3 program in fibromyalgia, and we are looking forward to the results of a planned interim analysis due next quarter, followed by topline results in the fourth quarter of this year. If successful, we believe it will be the second and final adequate and well-controlled efficacy trial required for filing a New Drug Application (NDA) for approval by the U.S. Food and Drug Administration (FDA)”, he added. “Moreover, we believe we have satisfied all the other clinical and non-clinical requirements for an NDA.”

Dr. Lederman added, “Patients and caregivers alike report widespread dissatisfaction with the three currently approved drugs for fibromyalgia – Lyrica®, Cymbalta®, and Savella®, and generic pregabalin and duloxetine – switching back and forth between them, and too often taking off-label products, including addictive opiates. Fibromyalgia affects between six and 12 million adults in the U.S. according to the American Pain Association, and there hasn’t been a new FDA drug approval in the category in more than a dozen years.”

Dr Lederman continued, “Our recently expanded late-stage clinical programs include four potentially pivotal Phase 2 trials. Two are currently enrolling, one in Long COVID and the other in chronic migraine. The two others – one in depression and the other in cocaine intoxication – are due to start enrolling. We expect to initiate enrollment in the depression study by the end of March, followed by the cocaine intoxication study in the second quarter of this year.”

“In summary”, he concluded, “these programs, together with several others in earlier development, represent a diverse portfolio of programs with multiple opportunities for value creation in 2023 and beyond.”

Recent Highlights—Key Product Candidates*

Central Nervous System (CNS) Pipeline

TNX-102 SL (cyclobenzaprine HCl sublingual tablet): small molecule for the management of fibromyalgia (FM)

• The first 50% of participants were randomized on December 19, 2022, in the RESILIENT study, a double-blind, randomized, placebo-controlled, potentially pivotal confirmatory Phase 3 study of TNX-102 SL for the management of fibromyalgia. Results from a planned interim analysis are expected in the second quarter of 2023, with topline results expected in the fourth quarter of 2023. A positive topline outcome, together with results from the previous positive Phase 3 RELIEF study, would support submission of an NDA.

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

• Enrollment continues in the PREVAIL study, a potentially pivotal Phase 2 study of TNX-102 SL for fibromyalgia-type Long COVID.
• During a February 2023 virtual event co-hosted by BIO and Solve M.E. titled, “Long COVID: What Will it Take to Accelerate Therapeutic Progress?”, the Company presented its analysis that the majority of Long COVID patients present with a constellation of symptoms called nociplastic pain that overlap with fibromyalgia, and Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) and that fibromyalgia-type Long COVID appears to be one of several chronic overlapping pain conditions (COPCs) that are related by sharing the neurological process called central sensitization.  

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

• In February 2023, Tonix announced that enrollment began in the potentially pivotal Phase 2 PREVENTION study of TNX-1900 for the prevention of migraine headache in chronic migraineurs. The double-blind, placebo-controlled study has a target enrollment of 300 participants at approximately 25 sites across the U.S. Results from a planned interim analysis after the first 50% of enrolled patients have completed the study are expected in the fourth quarter of 2023.
• In January 2023, data from clinical and nonclinical studies were presented at the 16th Annual Headache Cooperative of the Pacific (HCOP) Winter Conference by collaborator Professor David Yeomans. The oral presentation titled, “Primary vs Secondary Sex Hormones and Migraine,” includes research sponsored by and licensed by Tonix. Preliminary results from a positron emission tomography (PET) study in humans showed that intranasal application of a radioisotope of magnesium-potentiated oxytocin is delivered to the trigeminal ganglia which have known roles in migraine headaches. In addition, preliminary results of data collected from isolated human trigeminal ganglia neurons in vitro show co-expression of oxytocin receptors and calcitonin gene-related peptide (CGRP), which are believed to represent the first observation of oxytocin receptors in human trigeminal ganglia. Furthermore, the presentation highlights data which suggest a sex difference in oxytocin potency.
• Tonix announced data from an in vitro study describing the impact of oxytocin on isolated human sensory neurons, presented by collaborator Professor David Yeomans at Neuroscience 2022, the annual meeting of the Society for Neuroscience. The poster, titled “In Vitro Impact of Oxytocin on Human Sensory Neurons,” is the first to show that oxytocin receptors are present on human sensory neurons and that inflammation drives expression of oxytocin receptors on these neurons. The results of this study are consistent with data from animal models and provide support for the use of oxytocin for the treatment of pain.
• An investigator-initiated Phase 2 study of TNX-1900 in obesity-associated binge eating disorder is expected to start enrolling in the second quarter of 2023 directed by principal investigator Professor Elizabeth Lawson at the Massachusetts General Hospital, a teaching hospital of Harvard Medical School.

TNX-601 ER (tianeptine hemioxalate extended-release tablets): a once-daily orally-administered small molecule for the treatment of major depressive disorder (MDD), Posttraumatic Stress Disorder (PTSD), and neurocognitive dysfunction associated with corticosteroid use.

• Enrollment is expected to initiate in the first quarter of 2023 in the potentially pivotal Phase 2 ‘UPLIFT’ Study for the treatment of MDD. Results from planned interim analysis after the first 50% of enrolled patients have completed the study are expected fourth quarter 2023.
• TNX-601 ER represents a novel approach to treating depression in the U.S., since the active ingredient tianeptine induces a neuroprotective and resilient phenotype in both neurons and microglia under conditions of stress. In contrast, antidepressants that are marketed in the U.S. act by modulating neurotransmitter levels or receptor binding in the synapse. The Phase 2 UPLIFT study is a double-blind, randomized, multicenter, placebo-controlled study to evaluate the efficacy and safety of TNX-601 ER taken orally once-daily for 6 weeks to treat MDD. It is a parallel design study with two arms, a TNX-601 ER 39.4 mg arm and a placebo arm. A total of 300 participants will be randomized in a 1:1 ratio into the two arms across approximately 30 U.S. sites, enrolling adult patients 18-65 years old with a DSM-5 diagnosis of depression and a duration for the current major depressive episode (MDE) of at least 12 weeks. The primary efficacy endpoint is mean change from baseline in the Montgomery-Åsberg Depression Rating Scale (MADRS) total score at Week 6. Key secondary efficacy endpoints include the Clinical Global Impression of Severity Scale (CGI-S) and the Sheehan Disability Scale (SDS).

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

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

Rare Disease Pipeline

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

• TNX-2900 has been granted Orphan Drug designation from the FDA for the treatment of PWS.
• As previously mentioned, in 2022, Tonix delivered a presentation titled, “TNX-2900 (Intranasal Oxytocin + Magnesium) in Development for the Treatment of Hyperphagia in Adolescents and Young Adults with Prader-Willi Syndrome” at the World Orphan Drug Congress USA.

Immunology Pipeline

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

• A First-in-Human Phase 1 study is expected to start in the second quarter of 2023 of TNX-1500 for prophylaxis of organ rejection in adult patients receiving a kidney transplant.
• In February 2023, Tonix announced a research agreement with the University of Maryland, Baltimore, to study and assess the role of TNX-1500 in the prevention of heart xenograft rejection. The genetically engineered pig donors will be provided by the Revivicor Division of United Therapeutics Corporation. Preclinical xenotransplantation studies are expected to support an IND application.
• Tonix announced a research agreement with Boston Children’s Hospital to study TNX-1500 for the prevention of graft-versus-host diseases (GvHD) after hematopoietic stem cell transplantation (HCT) in animals. HCT from unrelated donors is a component of the treatment protocol for several hematologic malignancies, but GvHD complicates treatment and limits the success of engraftment after HCT.

Infectious Disease Pipeline

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

• A Phase 1 study in is expected to start in the second half of 2023.
• Tonix presented a development update from the Company’s TNX-801 vaccine program in an oral presentation at the World Vaccine and Immunotherapy Congress on December 1, 2022. The oral presentation titled, “Live Virus Smallpox and Monkeypox Vaccine,” describes the history of live virus vaccines and rationale for the development of the Company’s Recombinant Pox Virus (RPV) platform, including TNX-801 to protect against mpox and smallpox. Non-human primates vaccinated with TNX-801 were fully protected with sterilizing immunity from a lethal challenge with intra-tracheal monkeypox.
• A publication describing the activity of TNX-801 to protect non-human primates against a lethal challenge with intra-tracheal monkeypox was published in the peer-reviewed journal, Viruses (Noyce RS, et al. “Single Dose of Recombinant Chimeric Horsepox Virus (TNX-801) Vaccination Protects Macaques from Lethal Monkeypox Challenge.” Viruses. 2023 Jan 26;15(2):356. doi: 10.3390/v15020356. PMID: 36851570; PMCID: PMC9965234.)
