Eledon Announces Clinical Progress with Tegoprubart in the Prevention of Transplant Rejection

First participant dosed in clinical trial at University of Chicago Medicine assessing the use of tegoprubart to prevent islet cell transplant rejection in patients with type 1 diabetes

Company reports updated data from ongoing Phase 1b trial evaluating tegoprubart for prevention of rejection in kidney transplantation

IRVINE, Calif., May 07, 2024 (GLOBE NEWSWIRE) -- Eledon Pharmaceuticals, Inc. (“Eledon”) (NASDAQ: ELDN) today announced that the first participant in an investigator-led clinical trial has received an islet cell transplant and is being treated with a novel immunosuppression regimen including tegoprubart, the company’s novel anti-CD40L antibody, which is in development for the prevention of pancreatic islet cell transplant rejection in patients with type 1 diabetes. The study is being conducted by the research team at University of Chicago Medicine’s Pancreatic and Islet Transplant Program. Separately, the company reported updated data from its ongoing Phase 1b trial demonstrating tegoprubart successfully prevented kidney transplant rejection and was generally safe and well-tolerated.

In January 2024, Eledon announced a collaboration with the University of Chicago Transplant Institute for an investigator sponsored trial in pancreatic islet cell transplantation in patients with type 1 diabetes (NCT06305286). Eledon is supplying tegoprubart as a cornerstone component of the immunosuppressive regimen for trial participants and tegoprubart is being evaluated for the prevention of transplant rejection in the trial. Funding for the study includes grants from the Juvenile Diabetes Research Foundation (JDRF) and the Cure Alliance.

“There is clinical evidence from our studies and others conducted by the National Institute of Health’s Clinical Islet Transplantation Consortium that demonstrate islet cell transplantation may reverse diabetes by eliminating the need for exogenous insulin and reinstating metabolic control in selected patients with difficult to control type 1 diabetes. However, the required use of current standard of care anti-rejection medications, specifically calcineurin inhibitors, has limited the benefit of these procedures due to well-known associated toxicity to the islets, nephrotoxicity, neurotoxicity and risk of hypertension. We hope that tegoprubart will effectively protect islets from rejection without side effects related to current standard therapy,” said Piotr Witkowski, M.D., Ph.D., Director, Pancreatic and Islet Transplant Program, University of Chicago Medicine, and principal investigator of the trial with John Fung, M.D., Ph.D.
