Tegoprubart-treated patients maintained higher mean eGFR over time, including a statistically significant approximately 12 mL/min/1.73 m² advantage at month 18 versus tacrolimus (74 vs. 61 mL/min/1.73 m²; p<0.05)

No biopsy-proven acute rejection (BPAR) events were observed in tegoprubart-treated patients after the first six months post-transplant, compared with seven BPAR events (9.4% of tacrolimus-treated patients) reported in the tacrolimus arm

Patient-reported outcomes at 52 weeks favored tegoprubart, with statistically significant improvements versus tacrolimus on two validated measures of symptom burden

Conference call and webcast to be held today at 8:00 a.m. ET

IRVINE, Calif., June 22, 2026 (GLOBE NEWSWIRE) — Eledon Pharmaceuticals, Inc. (“Eledon”) (Nasdaq: ELDN) today announced new long-term data from its Phase 2 BESTOW clinical program evaluating tegoprubart in patients undergoing kidney transplantation, presented in oral and poster presentations at the American Transplant Congress (ATC) taking place June 20-24, 2026, in Boston, Massachusetts. The presentations highlight updated results from the Phase 2 BESTOW trial and new long-term follow-up data from the Phase 2 BESTOW extension study.

“These long-term data further strengthen our belief that tegoprubart has the potential to redefine the standard of care in transplant immunomodulation,” said David-Alexandre C. Gros, M.D., Chief Executive Officer of Eledon. “A statistically significant kidney function benefit at 18 months, no observed BPAR events after six months in tegoprubart-treated patients, favorable long-term safety and tolerability, and improved patient-reported outcomes collectively reinforce tegoprubart’s emerging, differentiated clinical profile as we prepare to advance into Phase 3 development.”

“For kidney transplant recipients, success is measured not only by preventing rejection, but by preserving kidney function and maintaining quality of life over the long term,” 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. “These data are especially encouraging because tegoprubart was associated with sustained kidney function and improvements in patient-reported measures of symptom burden compared with tacrolimus. Providing an effective alternative to tacrolimus-based immunosuppression remains one of the most important unmet needs in kidney transplantation, particularly because lifelong immunosuppression can affect both long-term graft survival and how patients feel and function every day.”

Efficacy Results

• Among patients who completed 12 months of treatment in the BESTOW study, 96% (49/51) of tegoprubart-treated patients and 86% (48/56) of tacrolimus-treated patients entered the BESTOW long-term extension study. As of the data cutoff, mean follow-up was 21 months, with: 89 patients followed through 18 months, 20 patients followed through 24 months, and the longest-followed ongoing patient followed for approximately 33 months.
• Kidney graft function, as assessed by estimated glomerular filtration rate (eGFR), stabilized after the first month of treatment and remained higher in tegoprubart-treated patients than in tacrolimus-treated patients at each reported time point. At month 18, tegoprubart-treated patients demonstrated a statistically significant approximately 12 mL/min/1.73 m² higher mean eGFR compared with tacrolimus-treated patients (74 vs. 61 mL/min/1.73 m²; p<0.05).
• No biopsy-proven acute rejection (BPAR) events were observed in tegoprubart-treated patients after the first six months of treatment. In the tacrolimus arm, seven of 11 total BPAR events (approximately 64% of BPAR events) occurred after six months, including two events after 12 months: one new case of active antibody-mediated rejection (aAMR) and one recurrent case of active T-cell-mediated rejection with aAMR.
• Patient-reported outcome measures demonstrated lower symptom burden among tegoprubart-treated patients compared with tacrolimus-treated patients at 52 weeks, with statistically significant improvements on the Modified Transplant Symptom Occurrence and Symptom Distress Scale (MTSOSD-59R; treatment difference: -12.2; 95% CI: -19.7, -4.6; p<0.05) and the KDQOL-36 Symptoms and Problems domain (treatment difference: 5.7; 95% CI: 1.0, 10.5; p<0.05).
• In an exploratory analysis of patients who experienced rejection post-transplant, those who remained on tegoprubart maintained higher mean eGFR than tacrolimus-treated patients who experienced rejection, with the observed difference increasing from approximately 15 mL/min/1.73 m² at 12 months to approximately 25 mL/min/1.73 m² at 21 months.
• Long-term follow-up from the Phase 1b study for patients treated at the 20 mg/kg dose of tegoprubart was consistent with the Phase 2 BESTOW results, with no BPAR episodes observed after six months in tegoprubart-treated patients. In the Phase 1b study, long-term data was available for 16 patients; eight patients have been followed through 24 months, and the longest-followed ongoing patient has been on tegoprubart for approximately 3.5 years.
  

Safety Results

• In the BESTOW long-term extension study, key central nervous system and kidney-related adverse events were observed more frequently in the tacrolimus arm than in the tegoprubart arm, including headache (12% vs. 2%), extremity pain (10% vs. 0%), fall or loss of balance (6% vs. 0%), and acute kidney injury (6% vs. 2%), respectively.
• Diarrhea was observed more frequently in the tacrolimus arm than in the tegoprubart arm during long-term follow-up (21% vs. 10%, respectively). This pattern was consistent with the first-year BESTOW results, in which diarrhea was reported in 34% of tacrolimus-treated patients vs. in 22% of tegoprubart-treated patients.
• No graft loss, no progressive multifocal leukoencephalopathy (PML), no post-transplant lymphoproliferative disorder (PTLD), no BK or CMV nephropathy/disease, and no new malignancies were reported in the BESTOW long-term extension study. No new proteinuria was reported on the tegoprubart arm. One death occurred in the tegoprubart arm and was not attributed to study drug.
  

Next Steps

Following a successful FDA End-of-Phase 2 meeting, Eledon has established the regulatory framework for its Phase 3 kidney transplantation program and plans to initiate Phase 3 clinical development of tegoprubart in late 2026. The Phase 3 primary endpoint is expected to be non-inferiority versus tacrolimus at 52 weeks on a composite of BPAR, graft loss and death. The Phase 3 study will also incorporate key learnings from the Phase 2 BESTOW trial and ongoing long-term extension study, including evidence of sustained kidney function benefit, favorable rejection outcomes, and improved patient-reported outcomes.

Reported updated results from 12 patients with type 1 diabetes treated with tegoprubart following islet transplantation in UChicago Medicine-led study

Presented 24-month follow-up data from Phase 1b long-term extension study which continues to support the favorable safety and tolerability profile of tegoprubart

Tegoprubart granted Orphan Drug designation by the FDA for the prevention of allograft rejection in liver transplantation

IRVINE, Calif., March 19, 2026 (GLOBE NEWSWIRE) — Eledon Pharmaceuticals, Inc. (“Eledon”) (Nasdaq: ELDN) today reported its fourth quarter and full year 2025 operating and financial results and reviewed recent business highlights.

“Over the past year, Eledon has made significant progress advancing tegoprubart, our anti-CD40L antibody, as a potential next-generation immunosuppressive therapy across multiple transplantation settings,” said David-Alexandre C. Gros, M.D., Chief Executive Officer of Eledon. “The over 100 patients treated across our transplantation programs to date provide a growing body of evidence that reinforces our conviction that tegoprubart can address key safety and efficacy issues with current standard-of-care transplant immunosuppression. Looking ahead, we anticipate multiple important milestones this year, including regulatory engagement to support advancement into Phase 3 development in kidney transplantation, initiation of an additional islet transplantation trial in type 1 diabetes, and the start of a clinical trial in liver transplantation.”

Fourth Quarter 2025 and Recent Corporate Developments

• Announced that tegoprubart has been granted Orphan Drug designation by the U.S. Food and Drug Administration (FDA) for the prevention of allograft rejection in liver transplantation. Tegoprubart previously received Orphan Drug designation from the FDA for the prevention of allograft rejection in pancreatic islet cell transplantation and for the treatment of amyotrophic lateral sclerosis (ALS).
• Presented 24-month follow-up data from eight patients enrolled in the Phase 1b long-term extension trial evaluating tegoprubart in kidney transplantation at the American Society of Transplant Surgeons Winter Symposium. The data continue to support the favorable safety and tolerability profile of tegoprubart with no episodes of biopsy-proven acute rejection, graft loss, death, new-onset diabetes mellitus, or de novo donor-specific antibody formation reported during the study period. Mean estimated glomerular filtration rate (eGFR) increased over the measurement period, from 67.0 mL/min/1.73 m² at 12 months to 74.2 mL/min/1.73 m² at 24 months.
• Reported updated results from 12 patients with type 1 diabetes treated with tegoprubart as the core immunosuppressant following islet transplantation in an investigator-initiated trial conducted at the University of Chicago Medicine Transplant Institute. All 10 patients who were more than four weeks post-transplant achieved 100% insulin independence and a most recent hemoglobin A1C (HbA1c) below 6.0%, with a mean most recent HbA1c across the 10 patients of approximately 5.35%. Tegoprubart-based immunosuppression was generally well tolerated with reported post-transplant immunosuppression-related adverse events successfully treated by lowering the mycophenolic acid dose, if necessary. There were no rejection episodes, and no patients developed de novo donor-specific HLA antibodies. Additionally, no evidence of nephrotoxicity, hypertension or neurotoxicity, which are commonly associated with tacrolimus-based immunosuppression regimens, was observed. The study continues to generate significant patient demand with inquiries received from several hundred T1D patients.

Anticipated Upcoming Milestones

• Receive FDA guidance on the Phase 3 trial design assessing tegoprubart in kidney transplantation, followed by initiation of the Phase 3 trial pending regulatory alignment.
• Report long-term data from Phase 1 and Phase 2 BESTOW studies evaluating tegoprubart in kidney transplantation.
• Receive FDA regulatory guidance on path to market for tegoprubart in islet cell transplantation and xenotransplantation.
• Initiate an investigator-led study evaluating tegoprubart for the prevention of organ rejection in patients with renal dysfunction receiving an islet cell transplant.
• Initiate an investigator-led study evaluating tegoprubart for the prevention of organ rejection in patients receiving a de novo liver transplant.
• Initiate an investigator-led study evaluating tegoprubart for kidney transplant tolerance induction.

Full Year 2025 Financial Results

Research and development (R&D) expenses for the year ended December 31, 2025 were $66.3 million, including $4.2 million of non-cash stock-based compensation expense, compared to $52.0 million, including $4.3 million of non-cash stock-based compensation expense, for the comparable period in 2024. The increase was primarily driven by continued advancement of the tegoprubart clinical development programs, including expanded clinical trial activity and manufacturing scale-up, as well as increased personnel to support these efforts.

General and administrative expenses for the year ended December 31, 2025 were $17.0 million, including $6.2 million of non-cash stock-based compensation expense, compared to $18.6 million, including $8.8 million of non-cash stock-based compensation expense, for the comparable period in 2024. The decrease was primarily driven by lower stock-based compensation expense, partially offset by higher professional services and personnel-related costs.

Net loss for the year ended December 31, 2025 was $45.6 million, or $0.52 per basic share of common stock, compared to a net loss of $36.2 million, or $0.66 per basic share of common stock, for the comparable period in 2024. The 2025 net loss included a non-cash gain of $33.4 million from changes in the fair value of warrant liabilities, while the 2024 net loss included a non-cash gain of $30.9 million from such changes. Excluding the non-cash items related to changes in the fair value of warrant liabilities, Eledon would have recorded a net loss of $79.1 million for the year ended December 31, 2025 and $67.1 million for the year ended December 31, 2024.

– 12-patient cohort fully enrolled with an average time since transplant of approximately 8 months

– 100% insulin independence achieved in 10 patients who are over 4 weeks post-transplant

– No signs of graft rejection or de novo donor-specific HLA antibodies

– Tegoprubart continues to demonstrate a favorable safety and tolerability profile

IRVINE, Calif, March 16, 2026 (GLOBE NEWSWIRE) — Eledon Pharmaceuticals, Inc. (“Eledon”) (NASDAQ: ELDN) today announced updated results from an investigator-initiated trial conducted at the University of Chicago Medicine Transplant Institute and presented by Piotr Witkowski, M.D., Ph.D., Director of the Pancreas and Islet Transplant Program at UChicago Medicine, at the Advanced Technologies and Treatments for Diabetes (ATTD) conference, held March 11-14, 2026 in Barcelona, Spain.

The investigator-initiated pilot study enrolled 12 adults with long-standing type 1 diabetes undergoing allogeneic islet transplantation at UChicago Medicine. Patients had a median duration of diabetes of approximately 33 years and mean hemoglobin A1C (“HbA1C”) of approximately 8.0% prior to transplantation. Participants received tegoprubart, Eledon’s anti-CD40L monoclonal antibody, as part of a calcineurin inhibitor-free immunosuppression regimen.

The data demonstrated rapid improvement in glycemic control following islet transplantation, with stable islet graft function observed across the cohort. All 10 patients who were more than four weeks post-transplant achieved both insulin independence and a most recent HbA1c below 6.0%, with a mean most recent HbA1c across the 10 patients of approximately 5.35%. Tegoprubart-based immunosuppression was generally well tolerated with reported post-transplant immunosuppression-related adverse events successfully treated by lowering the mycophenolic acid dose, if necessary. There were no rejection episodes, and no patients developed de novo donor-specific HLA antibodies. Additionally, no evidence of nephrotoxicity, hypertension or neurotoxicity, which are commonly associated with tacrolimus-based immunosuppression regimens, was observed. These findings further support the potential of CD40L blockade to enable effective islet graft protection while avoiding the toxicities of calcineurin inhibitors.

“T1D patients have been waiting decades for a potential functional cure, and it is very encouraging to see meaningful progress in that direction through the emerging promise of tegoprubart,” said David-Alexandre C. Gros, M.D., Chief Executive Officer of Eledon. “These latest findings support the potential of tegoprubart to enable effective islet graft protection while avoiding the toxicities often associated with calcineurin inhibitors, and potentially enable access to islet cell transplantation for individuals living with T1D. We are proud to contribute to these important ongoing research efforts and support the work of Dr. Witkowski and the team at UChicago Medicine. We also look forward to working closely with the FDA towards our goal of receiving regulatory guidance on a path to market for tegoprubart in islet cell transplantation later this year.”

“Breakthrough T1D is proud to fund the University of Chicago’s clinical trial testing tegoprubart as a novel immunosuppression alternative for use in islet cell transplants and we are very encouraged by the early data,” said Aaron Kowalski, Ph.D., CEO of Breakthrough T1D. “It is exciting to see islet transplant recipients in this trial who no longer need to administer insulin and who are experiencing fewer side effects than with traditional immunosuppressive regimens.”

This UChicago Medicine-initiated clinical trial is funded by Breakthrough T1D, with initial support from The Cure Alliance. Breakthrough T1D has also committed to fund a second study evaluating tegoprubart as part of a calcineurin inhibitor-free immunosuppression drug regimen to prevent islet transplant rejection in individuals with T1D and chronic kidney disease.

About Islet Transplantation for Type 1 Diabetes

Pancreatic islet transplantation is a minimally invasive procedure developed to provide blood glucose control for subjects with type 1 diabetes and minimize or eliminate dependence on insulin. During the procedure, pancreatic islets containing insulin-producing beta cells are isolated from the pancreas of a deceased organ donor and infused through a small catheter into the patient’s liver. The islet cells lodge in small blood vessels in the liver and release insulin. After the procedure, subjects remain on immunosuppression therapy to prevent transplant rejection.

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, islet cell transplantation, liver allograft transplantation and amyotrophic lateral sclerosis (ALS).

IRVINE, Calif., March 10, 2026 (GLOBE NEWSWIRE) — Eledon Pharmaceuticals, Inc. (“Eledon”) (NASDAQ: ELDN) today announced that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug designation to tegoprubart for the prevention of allograft rejection in liver transplantation. Tegoprubart has previously received orphan drug designation from the FDA for the prevention of allograft rejection in pancreatic islet cell transplantation and for the treatment of amyotrophic lateral sclerosis (ALS).

“Clinical studies in kidney transplantation have demonstrated that tegoprubart has the potential to improve graft survival and function while reducing the side effects associated with calcineurin inhibitors, supporting its promise as a novel immunosuppressive therapy across multiple organ transplant settings,” said David-Alexandre C. Gros, MD, Chief Executive Officer of Eledon. “Based on the encouraging preclinical evidence we have generated to date, we believe liver transplantation represents a significant incremental opportunity for tegoprubart, and we look forward to evaluating its potential in the clinical setting through an anticipated investigator sponsored trial initiating later this year.”

Orphan Drug Designation is intended to support the development of therapies for rare diseases, defined as conditions affecting fewer than 200,000 people in the United States or fewer than 5 in 10,000 individuals in the European Union. These designations provide sponsors with a range of incentives intended to encourage the development of medicines for diseases with high unmet medical needs.
