(Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced that it has entered into a sponsored research agreement with Boston Children's Hospital to study TNX-15001 (Fc-modified anti-CD40L mAb) for the prevention of graft-versus-host disease (GvHD) after hematopoietic stem cell transplantation (HCT) in animals. The principal investigator is Leslie S. Kean M.D., Ph.D., Director, Stem Cell Transplantation Program, Division of Hematology/Oncology, Boston Children’s Hospital, Department of Pediatric Oncology, Dana-Farber Cancer Institute and Robert A. Stranahan Professor of Pediatrics, Harvard Medical School. The primary objective of the preclinical research study is to study the activity of TNX-1500 administered prophylactically to modify GvHD progression in animals after HCT to support an Investigational New Drug (IND) application for human studies. A Phase 1 study of TNX-1500 to assess pharmacokinetics and tolerability is expected to start in the first half of 2023. “We are excited to work with Leslie Kean on studying the potential of TNX-1500 for preventing GvHD after HCT,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Stem cell transplantation is an essential component of the treatment of several blood cell or hematologic cancers, but GvHD remains the most deadly complication, and limits the success of this otherwise life-saving treatment. To date, there has not been a humanized anti-CD40L antibody that can effectively prevent transplant rejection or GvHD with acceptable levels of tolerability. 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. We are excited to sponsor this study of testing anti-CD40L in HCT to potentially replace cyc...
