[{"type":"text","content":"Research Directed by Faculty of the Center for Transplantation Sciences, Massachusetts General Hospital TNX-1500 is Expected to Enter Phase 1 Clinical Development in Third Quarter 2023 CHATHAM, N.J, June 07, 2023 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced data from two oral presentations and one poster presentation at the 2023 American Transplant Congress (ATC) by faculty at the Center for Transplantation Sciences, Massachusetts General Hospital. The data involve studies of Tonix’s TNX-1500 (Fc-modified anti-CD40L monoclonal antibody) in development for the prevention of organ transplant rejection. The molecular target of TNX-1500 is CD40-ligand (CD40L), which is also known as CD154. Copies of the presentations are available on the Tonix Pharmaceuticals website at www.tonixpharma.com. The oral presentations titled, “Fc-Modified anti-CD154 Mab Induced Long Term Renal Allograft Survival without Thromboembolic Complications” by Dr. Ryo Otsuka et al. and “Efficacy of CD154 Blockade with TNX-1500 to prevent heart allograft immune injury” by Dr. Ikechukwu Ileka et al., and the poster presentation titled “anti-CD154 mAb (TNX-1500) Alone, or in Combination with Rapamycin, MMF, or anti-CD28 mAb (VEL-101) Prolongs Cynomolgus Cardiac Allograft Survival” by Dr. Kohei Kinoshita et al. include data demonstrating that TNX-1500 showed activity in preventing organ rejection and was well tolerated in non-human primates. Blockade of CD40L with TNX-1500 monotherapy consistently prevented pathologic alloimmunity in non-human primate kidney and cardiac allograft models without clinical thrombosis. Dr. Kinoshita was recognized with “Poster of Distinction” for his poster presentation. “The animal studies found that TNX-1500 retains activity to prevent rejection and preserve graft function, which we believe provides strong rationale for us to pursue development of TNX-1500 to prevent rejection in human transplant,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “We expect to begin a Phase 1 trial with TNX-1500 in the third quarter of 2023. There remains a significant need for new treatments with improved activity and tolerability to prevent organ transplant rejection. TNX-1500 is a third generation anti-CD40L mAb t...
