Exhibit 99.1
Eledon Presents Phase 2 BESTOW Trial Results for Tegoprubart for the Prevention of Rejection in Kidney Transplantation at the American Society of Nephrology’s Kidney Week 2025 Annual Meeting
Data from patients who remained on tegoprubart for a year post transplant showed an overall mean 12-month estimated glomerular filtration rate (eGFR) of approximately 69 mL/min/1.73 m²
Tegoprubart demonstrated a favorable safety and tolerability profile, substantially reducing the metabolic, neurologic, and cardiovascular toxicities commonly associated with tacrolimus
Supports advancement into Phase 3 development as a potential new standard for the prevention of kidney transplant rejection
Conference call to be held Friday, November 7 at 8:00 a.m. ET
IRVINE, Calif., November 06, 2025 (GLOBE NEWSWIRE) -- Eledon Pharmaceuticals, Inc. (“Eledon”) (NASDAQ: ELDN) today announced results from its Phase 2 BESTOW trial evaluating tegoprubart for the prevention of organ rejection in patients receiving a de novo kidney transplant. Results from the Phase 2 BESTOW clinical trial were presented today as a late breaking oral presentation titled “Efficacy and Safety of Tegoprubart for the Prevention of Rejection in Kidney Transplantation: Results from the Phase 2 BESTOW Trial,” at the American Society of Nephrology’s Kidney Week 2025 Annual Meeting in Houston, TX.
“The Phase 2 BESTOW data results demonstrate tegoprubart’s potential to maintain excellent kidney function while reducing the chronic metabolic, neurologic, and cardiovascular toxicities that burden patients on tacrolimus,” said David-Alexandre C. Gros, M.D., Chief Executive Officer of Eledon. “By pairing strong immunosuppressive efficacy with a differentiated safety profile, including dramatically lower rates of new-onset diabetes, tremor, and dialysis-requiring delayed graft function, tegoprubart represents a promising next-generation option for kidney transplant immunosuppression as we advance into Phase 3.”
“There remains a significant unmet need for safer alternatives to traditional tacrolimus-based immunosuppression regimens—options that can reduce harmful side effects without compromising efficacy. The Phase 2 results presented at ASN Kidney Week highlight the potential of tegoprubart to deliver strong graft function after kidney transplantation, while avoiding the long-term toxicities often associated with current standard of care,” said Andrew Adams, M.D., Ph.D., Professor of Surgery and Chief, Division of Transplantation, John S. Najarian Surgical Chair in Clinical Transplantation, Department of Surgery, University of Minnesota. “It’s been more than a decade since we’ve seen true innovation in transplant immunosuppression. These data offer real
Exhibit 99.1
hope that patients may soon have a transformative therapy that improves their health outcomes and overall quality of life.”
Study Design
The 12-month, randomized, head-to-head, Phase 2 study enrolled 127 kidney transplant recipients (63 receiving tegoprubart and 64 receiving tacrolimus) across 44 global sites. The study directly compared tegoprubart-based immunosuppression with a tacrolimus-based regimen. All patients also received rabbit antithymocyte globulin (rATG) induction and maintenance therapy with mycophenolate mofetil (MMF/MPA) and corticosteroids.
The study’s primary efficacy endpoint was the change in eGFR at 12 months post-transplant. Secondary endpoints included biopsy-proven acute rejection (BPAR), patient and graft survival, composite efficacy failure, iBox score, donor-specific antibodies (DSAs), delayed graft function (DGF), and new-onset diabetes after transplantation (NODAT).
Safety Results
Safety findings underscore tegoprubart’s potential to maintain effective immunosuppression while minimizing the metabolic, neurologic, and cardiovascular toxicities characteristic of tacrolimus-based therapy.
Efficacy Results
Exhibit 99.1
Next Steps
Based on these results, Eledon plans to advance tegoprubart into Phase 3 development following discussions with regulators on study design and data requirements. Insights from the Phase 2 BESTOW data set and the ongoing long-term extension study will be incorporated to optimize the Phase 3 protocol and strengthen the regulatory package.
Estimated cash, cash equivalents and short-term investments totaled approximately $93.4 million as of September 30, 2025. The company expects current cash, cash equivalents and short-term investments to fund operations to late 2026.
