CHATHAM, N.J., March 03, 2022 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced that the U.S. Food and Drug Administration (FDA) has granted Orphan-Drug Designation for TNX-2900* (intranasal potentiated oxytocin) for the treatment of Prader-Willi syndrome.
“Orphan-Drug Designation by the FDA is an important milestone and further validates our efforts to investigate the utility of TNX-2900 for Prader-Willi syndrome,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “It underscores the urgent, unmet medical need for patients diagnosed with this disease, and will benefit us as we continue to advance our program.”
As recently announced, Tonix entered into a sponsored research agreement with Inserm Transfert, the private subsidiary of Inserm, on behalf of Inserm (the French National Institute of Health and Medical Research) and Aix-Marseille Université to study oxytocin in the genetically engineered mouse model of Prader-Willi syndrome, a rare genetic disorder that causes distinct, but related pathological eating disorders in adults and newborns. In adults, Prader-Willi causes hyperphagia, or pathological over-eating, which leads to obesity and other complications associated with significant mortality. In newborns, Prader-Willi causes a deficiency in suckling, which has been shown to be normalized by oxytocin treatment
About Prader-Willi Syndrome
Prader-Willi syndrome is recognized as the most common genetic cause of life-threatening childhood obesity1 and affects males and females with equal frequency and all races and ethnicities. The hallmarks of Prader-Willi syndrome are lack of suckling in infants and, in children and adults, severe hyperphagia, an overriding physiological drive to eat, leading to severe obesity and other complications associated with significant mortality. There is currently no approved treatment for either the suckling deficit in babies or the obesity and hyperphagia in older children associated with Prader-Willi syndrome.

About TNX-2900 and Tonix’s Potentiated Oxytocin Platform
TNX-2900 is based on Tonix’s patented intranasal potentiated oxytocin formulation intended for use by adults and adolescents. Tonix’s patented potentiated oxytocin formulation is believed to increase specificity for oxytocin receptors relative to vasopressin receptors as well as to enhance the potency of oxytocin. Tonix is also developing a different intranasal formulation and device, designated TNX-1900, for prophylaxis of chronic migraine and for the treatment of insulin resistance and related conditions. Oxytocin is a naturally occurring human hormone that acts as a neurotransmitter in the brain. It was originally approved by the U.S. Food and Drug Administration 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 discontinued, and the New Drug Application was withdrawn.
