Eledon Pharmaceuticals announced updated results from an investigator-initiated trial conducted at the University of Chicago Medicine Transplant Institute and presented by Piotr Witkowski, M.D., Ph.D., Director of the Pancreas and Islet Transplant Program at UChicago Medicine, at the Advanced Technologies and Treatments for Diabetes conference, held March 11-14, 2026 in Barcelona, Spain. The investigator-initiated pilot study enrolled 12 adults with long-standing type 1 diabetes undergoing allogeneic islet transplantation at UChicago Medicine. Patients had a median duration of diabetes of approximately 33 years and mean hemoglobin A1C of approximately 8.0% prior to transplantation. Participants received tegoprubart, Eledon's anti-CD40L monoclonal antibody, as part of a calcineurin inhibitor-free immunosuppression regimen. The data demonstrated rapid improvement in glycemic control following islet transplantation, with stable islet graft function observed across the cohort. All 10 patients who were more than four weeks post-transplant achieved both insulin independence and a most recent HbA1c below 6.0%, with a mean most recent HbA1c across the 10 patients of approximately 5.35%. Tegoprubart-based immunosuppression was generally well tolerated with reported post-transplant immunosuppression-related adverse events successfully treated by lowering the mycophenolic acid dose, if necessary. There were no rejection episodes, and no patients developed de novo donor-specific HLA antibodies. Additionally, no evidence of nephrotoxicity, hypertension or neurotoxicity, which are commonly associated with tacrolimus-based immunosuppression regimens, was observed. These findings further support the potential of CD40L blockade to enable effective islet graft protection while avoiding the toxicities of calcineurin inhibitors.

Eledon Pharmaceuticals announced that the U.S. Food and Drug Administration, FDA, has granted Orphan Drug designation, ODD, to tegoprubart for the prevention of allograft rejection in liver transplantation. "Clinical studies in kidney transplantation have demonstrated that tegoprubart has the potential to improve graft survival and function while reducing the side effects associated with calcineurin inhibitors, supporting its promise as a novel immunosuppressive therapy across multiple organ transplant settings," said David-Alexandre C. Gros, MD, Chief Executive Officer of Eledon. "Based on the encouraging preclinical evidence we have generated to date, we believe liver transplantation represents a significant incremental opportunity for tegoprubart, and we look forward to evaluating its potential in the clinical setting through an anticipated investigator sponsored trial initiating later this year."

NewcelX (NCEL) announced a collaborative research agreement with Eledon Pharmaceuticals (ELDN). The collaboration is designed to advance combination strategies integrating NewcelX's lead program, NCEL-101, with Eledon's investigational anti-CD40L monoclonal antibody, tegoprubart, with the goal of supporting durable, immune-protected islet replacement and advancing a potential functional cure for Type 1 Diabetes.
