Eledon Pharmaceuticals Announces the First Patient Dosed in Phase 1b Trial Evaluating Tegoprubart in Kidney Transplantation

IRVINE, Calif., July 18, 2022 (GLOBE NEWSWIRE) -- Eledon Pharmaceuticals, Inc. (“Eledon”) (NASDAQ: ELDN), a patient-focused clinical stage biopharmaceutical company committed to the development of innovative and impactful treatments for organ and cell transplantation, autoimmune conditions, and neurodegenerative disease, today reported that the first patient has been dosed in a Phase 1b study to evaluate tegoprubart in patients undergoing kidney transplantation.

This open-label study, which has received clearance in Canada and the United Kingdom, is enrolling up to 12 patients who will undergo kidney transplantation. The patients will receive tegoprubart in combination with rabbit anti-thymocyte globulin (rATG) induction, and mycophenolate mofetil and an oral steroid taper as maintenance therapy. The study will evaluate the safety, pharmacokinetics, and efficacy of tegoprubart, including incidence of biopsy-proven acute rejection, immune cell infiltrate of graft biopsy, and biomarker measures of kidney injury and rejection risk.

More than 20,000 people a year undergo a kidney transplant in the United States, and another 90,000 people will wait an average of 3-5 years for a transplant. Re-transplants represent up to 15% of yearly transplant surgeries and thus decreasing the need for re-transplantation would lead to greater organ availability for new patients. In addition, tegoprubart seeks to address the challenges with current immunosuppressive calcineurin inhibitor (CNI)-based regimens, associated with up to an approximately 30% incidence of new onset diabetes post-transplant, as well as hypertension, kidney-toxicity and neuro-toxicity.

“We are pleased to announce that the first patient has been dosed with tegoprubart in our Phase 1b study for kidney transplantation. This trial marks a significant step towards our goal of providing a first line alternative to calcineurin inhibitors,” said David-Alexandre C. Gros, M.D., Chief Executive Officer of Eledon. “We believe tegoprubart has the potential to transform the clinical management of kidney transplantation by preventing graft rejection, mitigating the multiple toxicities associated with CNIs, and ultimately improving long term outcomes.”
