(Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced that David C. Yeomans, Ph.D., presented data from clinical and nonclinical studies in an oral presentation at the 16th Annual Headache Cooperative of the Pacific (HCOP) Winter Conference on January 27, 2023. The oral presentation titled, “Primary vs Secondary Sex Hormones and Migraine,” includes 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 presentation is available under the Scientific Presentations tab of the Tonix Pharmaceuticals corporate website at www.tonixpharma.com. “In addition to data showing that magnesium (Mg++) potentiates the analgesic effects of oxytocin, the presentation includes new preliminary data from a Positron Emission Tomography (PET) study in human volunteers dosed with a proprietary nitrogen-13 (13N) radioisotope of oxytocin formulated with Mg++,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “A signal was observed in the trigeminal ganglia, indicating that intranasal oxytocin plus Mg++ delivers oxytocin to the trigeminal ganglia which have known roles in migraine headache. These studies were a collaboration with Aarhus University and the principal investigator, Michael Winterdahl, PhD.” In addition to the PET study, the presentation includes data collected from isolated human trigeminal ganglia neurons in vitro which show oxytocin receptor co-expressed with calcitonin gene-related peptide (CGRP). The results of these studies, which were performed by postdoctoral fellow Vimala Bharadwaj, PhD, are believed to represent the first observation of oxytocin receptors in human tissue rather than in an animal model. Previously, it has been shown that oxytocin receptors and CGRP co-localize in rat trigeminal ganglia neurons....
