An Investigator Initiated Phase 2 Clinical Trial of TNX-1900 In Patients with Binge Eating Disorder Planned for Second Half 2022
Binge Eating Disorder is Estimated to Affect 2.8 Million American Adults1-3
Expands Uses of Tonix’s Proprietary Potentiated Oxytocin for Intranasal Administration to a Potential New Indication
CHATHAM, N.J., March 07, 2022 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced an agreement with Massachusetts General Hospital, a teaching hospital of Harvard Medical School, to evaluate TNX-1900* in an investigator initiated Phase 2 clinical trial as a potential treatment for patients with binge eating disorder. The Phase 2 clinical trial is expected to start in the second half of 2022.
“Binge eating disorder is a serious mental health condition associated with behavioral and metabolic morbidity for which there are few treatment options,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Oxytocin is a well-known natural hormone that is used therapeutically in certain other indications including as an i.v. medication for the induction of labor in pregnancy with a medical indication. We are hopeful that our proprietary intranasal dosage form will enhance its properties for use in the underserved population of patients suffering from binge eating disorder.”
TNX-1900* is also in development for the treatment of chronic migraine and is expected to enter a multi-site Phase 2 potential pivotal clinical trial for the prevention of migraine headache in chronic migraineurs in the second half of 2022.
“The binge eating disorder trial is expected to provide a rich source of data to evaluate the potential clinical benefit of TNX-1900 on binge eating disorder, which is often seen in association with other behavioral conditions such as depression, substance abuse and posttraumatic stress disorder, and is often under-diagnosed and under-treated,” said Elizabeth A. Lawson, M.D., M.M.Sc., Director, Interdisciplinary Oxytocin Research Program, Neuroendocrine Unit, Massachusetts General Hospital and Associate Professor of Medicine at Harvard Medical School and principal investigator of the trial. “While available psychological and pharmacological treatments produce remission from binge eating in some cases, up to 50% of patients continue to binge, and weight loss in those with obesity is difficult to achieve and sustain. There is accumulating evidence that oxytocin may reduce food intake by acting on neural pathways involved in reward and impulse control, which have been implicated in binge eating disorder. We are excited to investigate TNX-1900 as a potential novel therapy to reduce binge eating and excess body weight in individuals with binge eating disorder.”
Dr. Lawson previously led a program of research suggesting intranasal oxytocin reduces food intake, modulates the neural circuitry driving eating behavior, and enhances impulse control in men with overweight and obesity.4-7
The planned investigator initiated Phase 2 clinical trial will be a randomized, double-blind, placebo-controlled study of 60 patients with binge eating disorder and obesity. The 8-week study will evaluate the efficacy and safety of TNX-1900 as a treatment for binge eating disorder and determine whether TNX-1900 reduces bingeing frequency and body weight in adults with binge eating disorder and obesity, and underlying mechanisms.
* TNX-1900 is an investigational new drug and has not been approved for any indication.

About Binge Eating Disorder
Binge-eating disorder is a psychiatric illness characterized by frequent episodes of uncontrollable consumption of large amounts of food. It is the most common eating disorder and often leads to obesity-associated complications and later psychopathology1. Binge eating disorder is characterized by increased homeostatic appetite and sensitivity to reward (including food reward), which may lead to initiation of binge episodes, and a reduced ability to control behavioral impulses and formed habits, creating an imbalance in the sensitive interplay between these bottom-up and top-down processes governing the adaptive regulation of food intake and energy balance2-5.

About TNX-1900 and Tonix’s Potentiated Oxytocin Platform
TNX-1900 is based on a proprietary potentiated formulation of oxytocin and is currently being developed as a candidate for prophylaxis of chronic migraine, the treatment of insulin resistance1 and related conditions.TNX-1900 is based on Tonix’s patented intranasal potentiated oxytocin formulation. Tonix is also developing a different intranasal formulation, designated TNX-2900, for the treatment of Prader-Willi syndrome. 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 withdrawn, and the New Drug Application has been discontinued. TNX-1900 and TNX-2900 are in the pre-Investigational New Drug stage and have not been approved for any indication.
