CHATHAM, N.J., Nov. 16, 2022 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP), a clinical-stage biopharmaceutical company, today announced data describing the impact of oxytocin on isolated human sensory neurons, presented at Neuroscience 2022, the annual meeting of the Society for Neuroscience. A copy of the poster is available under the Scientific Presentations tab of the Tonix website at www.tonixpharma.com.
“This study of the effects of oxytocin on isolated human sensory neurons adds to the growing evidence that oxytocin plays a key role in pain modulation. The potential for intranasal oxytocin to be used as a non-opioid analgesic warrants further investigation,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “To that end, we look forward to initiating our Phase 2 study of intranasal oxytocin in chronic migraine by the end of 2022.”
Professor David Yeomans, Director of Pain Research at Stanford said, “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 study also showed that oxytocin inhibits these neurons, suggesting a mechanism by which oxytocin can produce analgesia. The study also showed the critical contribution of magnesium to this analgesia, as the impact of oxytocin on the sensory neurons was dramatically enhanced in the presence of supraphysiologic levels of this ion, and are consistent with prior work which demonstrated that magnesium ions (Mg2+) bind to a pocket in the oxytocin receptor, enhancing the activity of oxytocin at its receptor. The results of this study are consistent with data from animal models and provide support for the use of oxytocin agonists for the treatment of pain.”
In late 2021, Tonix received Investigational New Drug (IND) clearance from the U.S. Food and Drug Administration (FDA) to support the initiation of a Phase 2 study of TNX-1900 (intranasal potentiated oxytocin) for the prevention of migraine headache in chronic migraineurs. The Company expects to begin enrollment in the Phase 2 study during the fourth quarter of 2022.

Tonix is a clinical-stage biopharmaceutical company focused on discovering, licensing, acquiring and developing therapeutics to treat and prevent human disease and alleviate suffering. Tonix’s portfolio is composed of central nervous system (CNS), rare disease, immunology and infectious disease product candidates. Tonix’s CNS portfolio includes both small molecules and biologics to treat pain, neurologic, psychiatric and addiction conditions. Tonix’s lead CNS candidate, TNX-102 SL (cyclobenzaprine HCl sublingual tablet), is in mid-Phase 3 development for the management of fibromyalgia with a new Phase 3 study launched in the second quarter of 2022 and interim data expected in the second quarter of 2023. TNX-102 SL is also being developed to treat Long COVID, a chronic post-acute COVID-19 condition. Tonix initiated a Phase 2 study in Long COVID in the third quarter of 2022 and expects interim data in the second quarter of 2023. 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 first quarter of 2023. TNX-1900 (intranasal potentiated oxytocin), a small molecule in development for chronic migraine, is expected to enter the clinic with a Phase 2 study in the fourth quarter of 2022. TNX-601 ER (tianeptine hemioxalate extended-release tablets) is a once-daily formulation of tianeptine being developed as a potential treatment for major depressive disorder (MDD) with a Phase 2 study expected to be initiated in the first quarter of 2023. Tonix’s rare disease 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 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 and xenograft rejection and for the treatment of autoimmune diseases. A Phase 1 study of TNX-1500 is expected to be initiated in the first half of 2023. Tonix’s infectious disease pipeline consists of a vaccine in development to prevent smallpox and monkeypox, next-generation vaccines to prevent COVID-19, and a platform to make fully human monoclonal antibodies to treat COVID-19. TNX-801, Tonix’s vaccine in development to prevent smallpox and monkeypox, also serves as the live virus vaccine platform or recombinant pox vaccine (RPV) platform for other infectious diseases. A Phase 1 study of TNX-801 is expected to be initiated in Kenya in the first half of 2023. Tonix’s lead vaccine candidate for COVID-19 is TNX-1850, a live virus vaccines based on Tonix’s recombinant pox live virus vector vaccine platform.
