TNXP - Tonix Pharmaceuticals Announces Issuance of EU Patent Covering Intranasal Potentiated Oxytocin (TNX-1900) for the Treatment of Pain | Benzinga
New patent expected to expire in 2036
Proof of concept data from Phase 2 study for prevention of migraine headache expected in early December 2023
CHATHAM, N.J., Oct. 04, 2023 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (NASDAQ:TNXP), a clinical-stage biopharmaceutical company, announced today that the European Patent Office (EPO) issued European Patent No. 3242676 to the Company on October 4, 2023. The patent, entitled "Magnesium-Containing Oxytocin Formulations and Methods of Use", claims methods and compositions for treating pain, including migraine headaches, using intranasal magnesium-containing oxytocin formulations. This patent, excluding possible patent term extensions, is expected to provide Tonix with market exclusivity in the member states of the European Patent Office until 2036. The U.S. Patent and Trademark Office (USPTO) has previously issued U.S. Patents No. 9,629,894 and 11,389,473 which are expected to provide market exclusivity in the U.S. until 2036.
In August 2023, Tonix announced it completed enrollment in its proof-of-concept Phase 2 PREVENTION study of TNX-1900 (intranasal potentiated oxytocin) for the prevention of migraine headache in chronic migraineurs with a total of 88 patients enrolled. The Company expects topline results from this trial in early December 2023.
"We believe this European patent combined with the U.S. issuance provides a strong patent position for TNX-1900 as we move forward in clinical development for the treatment of chronic migraine," said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. "With a differentiated formulation including magnesium, which Tonix has shown to potentiate the action of oxytocin at oxytocin receptors in animal models, we believe TNX-1900 has the potential to help those chronic migraine sufferers by engaging and stimulating oxytocin receptors in the trigeminal ganglia. By expanding our patent coverage in Europe, we are ensuring the IP protection of this unique approach."
In addition to Tonix's patents that protect certain uses including treating migraine, Tonix has licensed patents from INSERM, the French national health and medical research institute, that claim methods of treating feeding disorders with onset during neonatal development, specifically Prader Willi syndrome and non-organic failure to thrive (NOFTT), using oxytocin (EP 2575853, US8853158 and US9125862) and licensed patents from University of Geneva that claim methods of treating insulin resistance using oxytocin (US9101569 and EP2571511).

It can also be accompanied by nausea, vomiting, visual disturbances, and sensitivity to bright light, strong smells, and loud noises.1 Epidemiological studies indicate that globally, approximately 1.2 billion individuals suffer from migraines annually.2 In the U.S., approximately 39 million Americans suffer from migraines and among these individuals, approximately four million experience chronic migraines (15 or more headache days per month).2
About TNX-1900
TNX-1900 (intranasal potentiated oxytocin) is a proprietary formulation of oxytocin in development as a candidate for prophylaxis of chronic migraine and for the treatment of craniofacial pain, insulin resistance and related 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 nose. Oxytocin is a naturally occurring human hormone that acts as a neurotransmitter in the brain. Oxytocin has no recognized addiction potential. It has ...
