PDF Version

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., Nov. 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 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.

• Metabolic effects: New-onset diabetes developed in approximately 1 in 6 patients receiving tacrolimus versus 1 in 47 receiving tegoprubart.
• Neurologic effects: Tremor was markedly higher in the tacrolimus group (25.0% vs. 1.6%).
• Cardiovascular effects: Hypertension (15.9% vs. 25.0%), hypertensive crisis (1.6% vs. 7.8%), and heart failure (0% vs. 4.7%) all favored tegoprubart.
• Renal recovery: Delayed graft function occurred less often with tegoprubart and required shorter dialysis (14.3% vs. 25.0%; 4.6 days vs. 6.1 days), suggesting potential reductions of 115 days on dialysis post-transplant per 100 deceased donor kidney recipients on tegoprubart vs. tacrolimus.
• Infections: Sepsis or bacteremia occurred more frequently in the tacrolimus arm (17.2% vs. 4.8%). Viral infection rates (CMV, BK, EBV, fungal) were similar across groups, with no cases of Post-Transplant Lymphoproliferative Disorder (PTLD) or Progressive Multifocal Leukoencephalopathy (PML).
• Overall rates of serious adverse events were comparable between treatment arms.

Efficacy Results

• eGFR on tegoprubart treatment was 69 mL/min/1.73 m² (n=51) at 12 months vs. 66 mL/min/1.73 m² for tacrolimus (n=56). Although the primary endpoint did not reach statistical significance, tegoprubart maintained strong renal function, delivering what the Company believes is the highest mean eGFR level reported to date in kidney transplant clinical trials evaluating rejection prevention.
  • Subgroup analyses demonstrated higher eGFRs in nearly all tegoprubart subgroups compared with tacrolimus, particularly among living-related donor recipients (~72 mL/min/1.73 m² vs. 62 mL/min/1.73 m²) and high Kidney Donor Profile Index (KDPI > 35) transplants (~62 mL/min/1.73 m² vs. 53 mL/min/1.73 m²).
  • In the deceased donor subgroup, tegoprubart achieved a mean eGFR of approximately 68 mL/min/1.73 m² at 12 months.
• The efficacy failure composite endpoint, comprising death, graft loss and biopsy proven acute rejection, is the approval endpoint currently recognized by the U.S. Food and Drug Administration. Efficacy failure composite endpoint was 22% in the tegoprubart group vs. 17% in the tacrolimus group, demonstrating non-inferiority for tegoprubart vs. tacrolimus, using a 20% non-inferiority margin. The Company believes these results, if replicated in a Phase 3 study, would be sufficient to support tegoprubart’s approvability.
  • The rate of acute rejection in all biopsies was 20.6% in the tegoprubart group compared with 14.1% in the tacrolimus group.
  • Among patients in the tegoprubart group who experienced acute rejection and remained on treatment through month 12, mean eGFR was 73 mL/min/1.73 m², compared with 50 mL/min/1.73 m² in those who switched to tacrolimus.
• There was 1 case of donor-specific antibodies (DSA) in the tegoprubart arm vs. 2 in the tacrolimus arm.

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.

Updated data from ongoing open-label Phase 1b trial demonstrated a mean 12-month eGFR of approximately 68 mL/min/1.73 m² post-transplant for patients on tegoprubart

Company on track to report topline results from Phase 2 BESTOW trial in kidney transplantation in November 2025

Cash, cash equivalents and short-term investments of $107.6 million as of June 30, 2025

IRVINE, Calif., Aug. 14, 2025 (GLOBE NEWSWIRE) — Eledon Pharmaceuticals, Inc. (“Eledon”) (Nasdaq: ELDN) today reported its second quarter 2025 operating and financial results and reviewed recent business highlights.

“We are proud to enter the second half of the year with strong momentum as we have achieved all of our key milestones to date including advancing tegoprubart in kidney, islet cell (type 1 diabetes), and liver allotransplantation, as well as in xenotransplantation. The positive data we recently presented at the World Transplant Congress reinforce the potential of tegoprubart to improve long-term transplant outcomes while reducing the toxic side effects often associated with the current standard of care,” said David-Alexandre C. Gros, M.D., Chief Executive Officer of Eledon. “With these encouraging results in hand, we look forward to sharing topline data later this year from our Phase 2 BESTOW trial in kidney transplantation and to continuing to explore tegoprubart’s broad potential in other transplant indications.”

Year-to-Date 2025 Business Highlights

• Presented updated data at the World Transplant Congress (WTC) in August 2025 from the ongoing Phase 1b open-label trial evaluating tegoprubart for the prevention of organ rejection in kidney transplant patients. Updated data from 32 participants demonstrated that tegoprubart continues to be well tolerated with no cases of death, graft loss, drug related tremor, sepsis, or new-onset diabetes. Kidney function, as assessed by estimated glomerular filtration rate (eGFR), generally stabilized after the first month post-transplant and remained in the range of approximately 68 mL/min/1.73 m² through 12 months for participants (n=12) who remained on tegoprubart. For comparison, data from historical studies using the standard of care, calcineurin inhibitor-based immunosuppression therapy, typically report aggregate mean eGFRs of approximately 53 mL/min/1.73 m² at 12 months after kidney transplant.
• In June 2025, a third patient was treated with tegoprubart as a cornerstone component of the immunosuppression treatment regimen following kidney xenotransplantation conducted at Massachusetts General Hospital (MGH) in collaboration with eGenesis.
• Announced the first three islet cell transplant recipients treated at the University of Chicago Medicine’s Transplant Institute in an investigator-initiated trial evaluating tegoprubart as part of an immunosuppression regimen for the prevention of islet transplant rejection achieved insulin independence. An additional three islet transplant recipients have now been enrolled as well, bringing the total enrollment in the trial to six patients.
• Preclinical data in liver allotransplantation utilizing tegoprubart was presented at WTC 2025 demonstrating markedly prolonged graft survival in non-human primates (NHPs) by targeting the CD40 Ligand pathway and the potential for transplant tolerance induction.
• Announced a second investigator-initiated trial at the University of Chicago Medicine’s Transplant Institute evaluating tegoprubart as part of an immunosuppression regimen for the prevention of islet transplant rejection in patients with impaired kidney function.
• Hosted an R&D Day in New York City that highlighted recent progress for the Company’s lead investigational candidate, tegoprubart, with a focus on its clinical development progress in organ and cell transplantation, including the ongoing Phase 2 BESTOW trial. The event featured members of Eledon’s executive team and leading experts in the field of transplantation. A replay of the R&D Day event can be found on Eledon’s website at https://ir.eledon.com/news-and-events/events
• In June 2025, the Company was added to the Russell 3000® and Russell 2000® Indexes following the annual reconstitution, broadening visibility among investors as Eledon approaches key regulatory milestones.

Anticipated Upcoming Milestones for 2H 2025

• November 2025: Report topline results from the Phase 2 BESTOW trial of tegoprubart in kidney transplantation.
• Launch an investigator-initiated trial at MGH evaluating tegoprubart as part of an immunosuppression regimen to induce donor-specific immune tolerance through mixed chimerism.
• Enroll three additional patients in the investigator-led clinical trial at UChicago Medicine in subjects with type 1 diabetes treated with tegoprubart as part of an immunosuppression regimen for the prevention of pancreatic islet transplant rejection.

Second Quarter 2025 Financial Results

Cash, cash equivalents and short-term investments totaled $107.6 million as of June 30, 2025 compared to $140.2 million as of December 31, 2024. The company expects current cash, cash equivalents and short-term investments to fund operations to the end of 2026.

Data from patients who remained on tegoprubart for a year showed overall mean 12-month eGFR of approximately 68 mL/min/1.73 m² post-transplant

Preliminary iBox data, a key biomarker of kidney function and immunologic response, supports that tegoprubart may improve 5-year graft survival vs. current standard of care

Tegoprubart continues to be well tolerated with no cases of death, graft loss, drug related tremor, or new-onset diabetes

Conference call to be held today at 4:30 p.m. ET

IRVINE, Calif., Aug. 06, 2025 (GLOBE NEWSWIRE) — Eledon Pharmaceuticals, Inc. (“Eledon”) (NASDAQ: ELDN) today announced updated data from the Company’s ongoing open-label Phase 1b trial evaluating tegoprubart for the prevention of organ rejection in kidney transplant patients. Results from the oral presentation, titled “Tegoprubart, an Anti-CD40L Antibody, for the Prevention of Rejection in Kidney Transplantation: An Ongoing Phase 1b Study,” were presented today at the World Transplant Congress (WTC) taking place in San Francisco, CA.

“The data presented today at WTC further reinforce our belief that tegoprubart has the potential to not only provide better protection and long-term preservation of kidney function following transplantation, but also to offer a safer alternative to traditional immunosuppressive therapies by minimizing harmful side effects,” said David-Alexandre C. Gros, M.D., Chief Executive Officer of Eledon. “The continued strength of the Phase 1b data through 12 months of treatment is highly encouraging as we look ahead to topline results from our Phase 2 BESTOW trial, expected in November, which compares tegoprubart to tacrolimus, the current standard of care.”

As of the July 2025 cutoff date, 32 patients undergoing kidney transplantation have been enrolled in the Phase 1b study. Updated data showed that kidney function, as assessed by estimated glomerular filtration rate (eGFR), stabilized after the first month post-transplant and remained in the range of approximately 68 mL/min/1.73 m² through 12 months for patients (n=12) who remained on tegoprubart​. Kidney function in the intention-to-treat population (n=15) was approximately 63 mL/min/1.73 m² at 12 months. Data from historical studies using the standard of care, calcineurin inhibitor-based immunosuppression therapy, typically report aggregate mean estimated glomerular filtration rates (eGFRs) of approximately 53 mL/min/1.73 m² during the first year after kidney transplant.

In addition, preliminary abbreviated iBox data was presented suggesting that tegoprubart may improve 5-year graft survival. Abbreviated iBox, a composite biomarker panel developed by the Paris Transplant Group, incorporates kidney function (eGFR, proteinuria) and immunologic response (donor-specific antibodies) parameters into a single prognostic score. Based on data collected to date, abbreviated iBox scores were ​-3.75 in the intention-to-treat population and -4.11 in the on-treatment population, which compare favorably to a -2.98 historical mean for calcineurin inhibitors. A difference in abbreviated iBox score of -0.40 at 12 months is considered predictive of a 4-5% difference in 5-year graft survival suggesting that tegoprubart may have a predicted 5-year allograft survival rate of over 96%.

Mean tegoprubart treatment exposure to date was 233 days. Tegoprubart continues to be well-tolerated with no cases of death, graft loss, drug related tremor, or new-onset diabetes, a side effect associated with standard of care immunosuppression therapy.

There were six (18.8%) rejection episodes, and 75% of patients who experienced a rejection had received low-dose rabbit antithymocyte globulin (rATG) induction. All rejection episodes were successfully treated. Of the patients who experienced a rejection episode and completed a year in the study, three who remained on tegoprubart had a mean eGFR of approximately 73 mL/min/1.73 m² at 12 months, indicating full recovery of kidney function, while the two patients who switched to standard of care tacrolimus had a mean eGFR of approximately 34 mL/min/1.73 m² at 12 months.

All 32 patients received rATG induction therapy and a maintenance regimen consisting of tegoprubart, mycophenolate mofetil, and corticosteroids.

• Cohort 1 has completed enrollment and evaluated tegoprubart at a dose of 20 mg/kg with rATG induction up to 6 mg/kg.
• Cohort 2 is currently enrolling and is evaluating a lower tegoprubart dose of 10 mg/kg, with a required rATG dose of 4.5 mg/kg.
• The primary endpoint of the study is safety and pharmacokinetics. Secondary and exploratory endpoints include patient and graft survival, biopsy-proven acute rejection, kidney function as measured by estimated by eGFR, and abbreviated iBox score.

Eledon is also conducting a Phase 2 trial (BESTOW; NCT05983770) 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. Topline results from the Phase 2 BESTOW trial are anticipated in November 2025.

About iBox

iBox is a composite biomarker panel developed by the Paris Transplant Group to predict long-term kidney graft survival. It combines kidney function (eGFR, proteinuria), immunologic response (donor-specific antibodies), and histopathology (Banff scores) into a single prognostic score. Validated across four independent cohorts, including two Phase 3 trials (BMS BENEFIT and BENEFIT-EXT), iBox has demonstrated strong predictive accuracy (C-statistic >0.8) for 5-year graft loss and outperforms traditional markers like biopsy-proven acute rejection. Both full and abbreviated iBox models have been qualified by the European Medicines Agency (EMA) and accepted by the U.S. FDA into the Biomarker Qualification Program. The iBox Composite Biomarker Panel is under review by the FDA as a Reasonably Likely Surrogate Endpoint (RLSE) for use as a co-primary endpoint in Phase 2/3 trials, supporting potential accelerated approval of novel immunosuppressive therapies. This makes iBox the first transplant-specific endpoint formally recognized under FDA’s biomarker qualification framework.

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). Eledon is headquartered in Irvine, California. For more information, please visit the Company’s website at www.eledon.com.
