(Nasdaq: TNXP) (Tonix or the Company), a biopharmaceutical company with marketed products and a pipeline of development candidates, today announced that a study published in the Journal Nature1 by faculty at the Center for Transplantation Sciences, Massachusetts General Hospital (MGH) in collaboration with biotechnology company, eGenesis, utilized TNX-1500 (Fc-modified dimeric anti-CD40L monoclonal antibody [mAb]) as part of the immune modulating regimen to prevent organ transplant rejection. Tonix’s TNX-1500 is in development for the prevention of human kidney organ transplant rejection. The molecular target of TNX-1500 is CD40-ligand (CD40L), which is also known as CD154. TNX-1500 was invented and developed in-house by Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals, and colleagues. TNX-1500 is a third generation anti-CD40L monoclonal antibody that has been designed by protein engineering to decrease FcγRII binding and to reduce the potential for thrombosis. Preclinical studies in non-human primates demonstrated that TNX-1500 showed activity in preventing allograft and xenograft organ rejection and was well tolerated. The research in the Nature paper was conducted at MGH, led by principal investigator Tatsuo Kawai, M.D., Professor of Surgery, Harvard Medical School and the Center for Transplantation Science. A “News and Views” editorial2 and a News3 story appeared in the same issue of Nature. The Nature article titled, “Design and testing of a humanized porcine donor for xenotransplantation” includes data that provide additional support for TNX-1500’s activity in preventing pig xenograft organ rejection and for its tolerability in non-human primates. Because anti-CD40L treatment is widely recognized as critical to the success of xeno organ transplant, no animals were transplanted without anti-CD40L treatment. Four of the transplanted animals received prophylactic treatment with TNX-1500. The other anima...
