Eledon Announces Completion of Enrollment in Phase 2 BESTOW Clinical Trial Assessing Tegoprubart for Prevention of Organ Rejection in Kidney Transplant Patients

Enrollment Completed Four Months Ahead of Schedule

IRVINE, Calif., Sept. 04, 2024 (GLOBE NEWSWIRE) -- Eledon Pharmaceuticals, Inc. (“Eledon”) (NASDAQ: ELDN) today announced that it has successfully completed enrollment for its Phase 2 BESTOW clinical trial, which is designed to assess the safety and efficacy of its investigational immunosuppression therapy tegoprubart for the prevention of organ rejection in patients undergoing kidney transplantation. The trial reached its target enrollment of 120 participants approximately four months earlier than originally planned.

“We are very pleased to achieve this critical milestone ahead of schedule in our BESTOW trial,” said David-Alexandre C. Gros, M.D., Chief Executive Officer of Eledon. “The accelerated pace of enrollment reflects the strong interest among both clinicians and patients in new innovative therapies that have the potential to improve outcomes in kidney transplantation compared to current standard of care immunosuppression regimens. We are proud to be leading the effort to transform the prevention of organ rejection and based on the early completion of enrollment, we now anticipate reporting top-line results for the BESTOW trial in the fourth quarter of 2025.”

BESTOW, a multicenter, two-arm, active comparator clinical study, enrolled 120 participants undergoing kidney transplantation at sites in North America, Europe and Latin America to evaluate the safety, pharmacokinetics, and efficacy of tegoprubart, an anti-CD40 ligand antibody, compared to the calcineurin inhibitor tacrolimus. The study’s primary objective is to assess graft function at 12 months post-transplant, as measured by estimated glomerular filtration rate (eGFR), in participants treated with tegoprubart compared to tacrolimus. Research has shown that better graft function as assessed by eGFR has been associated with improved long-term graft survival following kidney transplantation.

“Completing enrollment in the Phase 2 BESTOW trial is a significant achievement for our team and, more importantly, for the transplant community,” said Steve Perrin, Ph.D., Chief Scientific Officer and President of Eledon. “It is a testament to the strong collaboration with our clinical sites and the enthusiasm within the community for advances in immunosuppression therapy, an area of research that has not seen major therapeutic innovation in decades. We are deeply grateful to the patients, their families, and the clinical teams for their continued support in advancing this important study.”

The BESTOW trial builds upon results from Eledon’s ongoing Phase 1b trial presented at the American Transplant Congress (ATC) in June 2024, and further demonstrates that tegoprubart has the potential to provide kidney transplant recipients with a safe and effective alternative to calcineurin inhibitors, which are often associated with side effects such as hyperglycemia, new onset diabetes, hypertension, or tremors. Eledon plans to continue advancing its tegoprubart clinical program with the goal of offering a new standard of care immunosuppression therapy for organ transplant patients.

Eledon is currently conducting the Phase 2 BESTOW trial (NCT05983770), the Phase 1b trial (NCT05027906), and a long-term safety and efficacy extension study (NCT06126380) to evaluate tegoprubart for the prevention of organ rejection in patients receiving a kidney transplant.

About Eledon Pharmaceuticals and tegoprubart

Eledon Pharmaceuticals, Inc. is a clinical stage biotechnology company that is developing immune-modulating therapies for the management and treatment of life-threatening conditions. The Company’s lead investigational product is tegoprubart, an anti-CD40L antibody with high affinity for the CD40 Ligand, a well-validated biological target that has broad therapeutic potential. The central role of CD40L signaling in both adaptive and innate immune cell activation and function positions it as an attractive target for non-lymphocyte depleting, immunomodulatory therapeutic intervention. The Company is building upon a deep historical knowledge of anti-CD40 Ligand biology to conduct preclinical and clinical studies in kidney allograft transplantation, xenotransplantation, and amyotrophic lateral sclerosis (ALS).
