(Nasdaq: TNXP), a biopharmaceutical company with marketed products and a pipeline of development candidates, today announced the results of modeling key human pharmacokinetic (PK) properties for TNX-1500 (Fc-modified humanized anti-CD40L monoclonal antibody, or mAb)* from animal studies. TNX-1500 is in development for the prevention of rejection in solid organ and bone marrow transplantation and for the treatment of autoimmune disorders. “For more than 30 years, anti-CD40L therapy has shown promise in transplantation and the treatment of autoimmunity, but first-generation humanized mAbs were associated with an increased risk of thrombosis and second-generation agents had poor PK properties or reduced activity,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Preclinical studies in non-human primates have shown that TNX-1500 maintains the activity of first generation mAbs, with reduced risk of thrombotic complications.3-5 Today we are announcing that modeling studies from animal PK data3, predict that a half-life of approximately three weeks for TNX-1500 in humans6,7, which supports monthly dosing. This PK analysis together with TNX-1500’s activity and tolerability in animals, suggests that the protein engineering of TNX-1500’s Fc region has achieved its design goals.” Dr. Lederman continued, “Recently, positive clinical data have been reported by Sanofi, with its Fc-modified humanized anti-CD40L mAb frexalimab in treating relapsing multiple sclerosis with monthly i.v. or biweekly s.c. dosing regimens.2 Based on its results in multiple sclerosis, Sanofi project...
