Data from 11 participants demonstrates tegoprubart successfully prevented kidney transplant rejection and was generally safe and well-tolerated
Aggregate mean eGFR was above 70 mL/min/1.73m2 at all reported time points after day 90 supporting tegoprubart’s potential to protect organ function in patients undergoing kidney transplantation
Eledon will host a conference call today at 5:00 p.m. ET
IRVINE, Calif., Nov. 02, 2023 (GLOBE NEWSWIRE) — Eledon Pharmaceuticals, Inc. (“Eledon”) (NASDAQ: ELDN) today reported results from the Company’s ongoing Phase 1b open-label trial evaluating tegoprubart for the prevention of rejection in patients undergoing de novo kidney transplantation. Results were presented at the American Society of Nephrology Kidney Week 2023 Annual Meeting taking place in Philadelphia, PA from November 2-5, 2023.
“We are excited to present updated safety and efficacy results from our ongoing Phase 1b trial which continue to support the potential of tegoprubart as a novel kidney transplant immunosuppressive therapy to prevent rejection and better preserve organ function without many of the side effects associated with tacrolimus, the current standard of care,” said David-Alexandre C. Gros, M.D., Chief Executive Officer. “We remain committed to the transplant community who are in urgent need of better treatment options, and we look forward to continuing this study in parallel with our Phase 2 BESTOW study initiated earlier this year.”
At the time of data submission, results from the 11 participants in the Phase 1b trial demonstrated that tegoprubart is generally safe and well-tolerated in patients undergoing kidney transplantation. There have been no cases of hyperglycemia, new onset diabetes, tremor, or cytomegalovirus infection commonly seen with tacrolimus. One participant experienced a mild T cell mediated rejection (Banff score 1a) on day 99. This patient was treated for the rejection and remains in the study. There were no cases of graft loss or death.
Aggregate mean estimated glomerular filtration rate (eGFR) – a measure of kidney function – was above 70 mL/min/1.73m2 at all reported time points after day 90. Historical studies have reported average eGFRs generally in the low 50 mL/min/1.73m2 range during the first year after kidney transplant using standard of care. One participant has completed the study with an eGFR of 91 at one year (day 374) and is now enrolled in a Phase 2 open-label extension (OLE) study, which will evaluate the long-term safety, pharmacokinetics, and efficacy of tegoprubart in participants who have completed one year of treatment in either the ongoing Phase 1b or Phase 2 BESTOW study.
“In this Phase 1b trial, patients treated with tegoprubart demonstrated robust improvements in eGFR with a strong safety profile,” said Dr. John S. Gill, MD, Professor of Medicine at the University of British Columbia, St. Paul’s Hospital, Vancouver, Canada, and Principal Investigator of the study. “These results further support the promise of CD40L costimulatory blockade in organ transplantation. I look forward to additional readouts from this study in 2024.”
The Phase 1b open-label study has enrolled 11 participants who underwent kidney transplantation in Canada, Australia, and the United Kingdom. Each participant received rabbit antithymocyte globulin (ATG) induction and a maintenance regimen consisting of tegoprubart, mycophenolate mofetil, and corticosteroids. The primary endpoint of the study is safety. Other endpoints include characterizing the pharmacokinetic profile of tegoprubart, the incidence of biopsy proven rejection, and eGFR.
In September, Eledon announced that the first participant had been dosed in the Company’s Phase 2 BESTOW trial evaluating tegoprubart for the prevention of organ rejection in patients receiving a kidney transplant. The multicenter, two-arm, active comparator clinical study is enrolling approximately 120 participants undergoing kidney transplantation in the United States and other countries to evaluate the safety, pharmacokinetics, and efficacy of tegoprubart compared to the calcineurin inhibitor tacrolimus. The BESTOW trial’s primary endpoint is designed to test the potential superiority of tegoprubart vs. tacrolimus in post kidney transplant kidney function at 12 months as measured by eGFR. The Company expects to complete enrollment at the end of 2024.

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 CD40 Ligand, a well-validated biological target within the costimulatory CD40/CD40L cellular pathway. 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). Eledon is headquartered in Irvine, California. For more information, please visit the company’s website at www.eledon.com.
