Tonix Pharmaceuticals Acquires Exclusive License to University of Geneva Technology for Oxytocin-Based Treatments for Treating Insulin Resistance, Diabetes and Obesity, Expanding Proprietary Uses for TNX-1900 (Intranasal Potentiated Oxytocin)
University of Geneva Technology Covers Broad Applications for Cardiometabolic Syndromes
CHATHAM, N.J., Dec. 22, 2020 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced an agreement whereby Tonix has acquired the exclusive license to the University of Geneva’s technology for using oxytocin to treat insulin resistance and related syndromes, including obesity, from privately held Katana Pharmaceuticals, Inc. This license allows Tonix to expand its intranasal potentiated oxytocin development program, TNX-1900, into cardiometabolic syndromes, which include insulin resistance, impaired glucose tolerance, and obesity. The patents covering the technology are expected to provide Tonix with freedom to operate in these indications as well as market exclusivity in the U.S. and Europe through 2031, upon its approval, independently of other Tonix-held patents covering the formulation and potentiation technologies related to TNX-1900.
The University of Geneva technology is based on the discovery that oxytocin administration in an animal model of obesity improved lipid metabolism by increasing lipolysis and fatty acid-β-oxidation in adipose tissue accompanied by improvements in glucose intolerance and insulin resistance, independent of food intake1.
“The important new technology from University of Geneva will allow Tonix to develop intranasal oxytocin on a broader platform to treat both central nervous system (CNS) and cardiometabolic conditions. We believe that TNX-1900 has the potential to be a safe, natural, non-addictive, and easy to administer treatment alternative for a number of CNS disease states. Our lead indication for TNX-1900 is for the treatment of migraine,” said Seth Lederman, M.D., President and Chief Executive Officer of Tonix Pharmaceuticals.
“Subsequent to the University of Geneva inventions, a number of studies have shown that intranasal oxytocin has effects on insulin resistance and weight2-4,” continued Dr. Lederman. “Intranasal oxytocin has been reported to improve glucose homeostasis, improve pancreatic β-cell responsivity, decrease energy-induced and reward-induced eating, and support cognitive control of food choices.2-9 The effects of intranasal oxytocin on improving peripheral insulin sensitivity, pancreatic function and lipid metabolism encourage us to develop TNX-1900 as a potential therapeutic in obesity, insulin resistance, diabetes management and related metabolic complications.”
In June 2020, Tonix acquired its potentiated oxytocin technology and development program from Trigemina, Inc., and assumed licenses for certain related technologies from Stanford University. TNX-1900 has demonstrated activity in several non-clinical studies in CNS disease models. In addition, prior to the acquisition from Trigemina, TNX-1900 was studied in the U.S. under a physician-requested Investigational New Drug Application .

About TNX-1900 (Intranasal Potentiated Oxytocin)*
TNX-1900, Tonix’s proprietary intranasal oxytocin is currently being studied as a candidate for prophylaxis of chronic migraine. TNX-1900 is in the pre-Investigational New Drug (IND) stage and has not been approved for any indication. It is based on a proprietary formulation of oxytocin and is being developed first for the treatment of migraine. Oxytocin is a naturally-occurring human hormone that acts as a neurotransmitter in the brain. It is approved by the U.S. Food and Drug Administration (FDA) as Pitocin®, an intravenous infusion or intramuscular injection drug, for use in pregnant women to induce labor. An intranasal form of oxytocin was marketed in the U.S. by Novartis to assist in the production of breast milk as Syntocinon® (oxytocin nasal 40 units/ml), but the product was withdrawn and the New Drug Application (NDA) has been discontinued. In clinical and preliminary research, it has been observed that low oxytocin levels in the body can lead to increase in headache frequency, and that increased oxytocin levels can relieve headaches. Oxytocin, when delivered via the nasal route, results in enhanced binding of oxytocin to receptors on neurons in the trigeminal system, inhibiting transmission of pain signals. Intranasal oxytocin has been well tolerated in several clinical trials in adults and children. Intranasal oxytocin has been shown to block calcitonin gene-related peptide (CGRP) release in animals, a pathway known to be critical to the pathogenesis of migraine attacks. TNX-1900 is believed to interrupt pain signals at the trigeminal ganglia by suppressing electrical impulses, a potentially different activity than drugs that just block CGRP. Migraine attacks are caused, in part, by the release of CGRP from pain-sensing nerve cells that are part of the trigeminal system. Targeted delivery results in low systemic exposure and lower risk of non-nervous system, off-target effects which could potentially occur with systemic CGRP antagonists. For example, CGRP has roles in dilating blood vessels in response to ischemia, including in the heart. Tonix believes targeted delivery of oxytocin could translate into selective blockade of CGRP release in the trigeminal ganglion and not throughout the body, which could be a potential safety advantage over systemic CGRP inhibition.
