Eledon Pharmaceuticals Announces Use of Tegoprubart as Key Component of Immunosuppression Regimen in its Second Transplant of a Genetically Modified Pig Kidney into a Human
Eledon Pharmaceuticals (NASDAQ: ELDN) announced that its investigational anti-CD40L antibody, tegoprubart, was used in a successful xenotransplantation of a genetically modified pig kidney into a human at Massachusetts General Hospital (MGH) on January 25, 2025. The patient has been discharged and is now off dialysis for the first time in over two years.
This marks the second kidney xenotransplant at MGH using tegoprubart as a key component of the immunosuppression regimen. The FDA approved MGH to perform two additional xenotransplants this year. Tegoprubart was also used in the second-ever pig-to-human heart transplant at the University of Maryland Medical Center in September 2023.
The drug is currently being evaluated in three global clinical studies for organ rejection prevention in kidney transplants and in a separate trial for islet transplant rejection in type 1 diabetes patients. Eledon plans to report interim clinical trial results in summer 2025 and topline results from its Phase 2 BESTOW kidney transplant trial in Q4 2025.
Eledon Pharmaceuticals (NASDAQ: ELDN) ha annunciato che il suo anticorpo sperimentale anti-CD40L, tegoprubart, è stato utilizzato con successo in una xenotrapianto di un rene di maiale geneticamente modificato in un paziente umano presso il Massachusetts General Hospital (MGH) il 25 gennaio 2025. Il paziente è stato dimesso ed è ora senza dialisi per la prima volta in oltre due anni.
Questo segna il secondo xenotrapianto di rene presso il MGH utilizzando tegoprubart come componente chiave del regime di immunosoppressione. La FDA ha approvato il MGH per eseguire due ulteriori xenotrapianti quest'anno. Tegoprubart è stato anche utilizzato nel secondo trapianto di cuore da maiale a umano presso l'Università del Maryland Medical Center nel settembre 2023.
Il farmaco è attualmente valutato in tre studi clinici globali per la prevenzione del rigetto d'organo nei trapianti di rene e in un trial separato per il rigetto del trapianto di isole nei pazienti con diabete di tipo 1. Eledon prevede di riferire i risultati provvisori degli studi clinici nell'estate del 2025 e i risultati principali del suo trial di Fase 2 BESTOW per il trapianto di rene nel quarto trimestre del 2025.

Insights
The successful use of tegoprubart in a second xenotransplantation represents a significant milestone in addressing the critical organ shortage crisis. This achievement is particularly noteworthy as it demonstrates reproducible success in xenotransplantation, a field that could revolutionize organ transplantation.
The drug's unique mechanism targeting CD40L positions it as a potential cornerstone therapy in transplantation. What's particularly compelling is the drug's versatility, being evaluated across multiple transplant scenarios:
- Prevention of rejection in kidney transplants (Phase 1b and Phase 2 BESTOW trial)
- Islet cell transplantation for Type 1 diabetes
- Xenotransplantation procedures (pig-to-human kidney and heart)
The upcoming clinical milestones create significant value-driving catalysts:
- Summer 2025: Phase 1b and long-term safety data in kidney transplant
- Q4 2025: Phase 2 BESTOW trial topline results
- 2025: Additional xenotransplants planned at MGH
The early success in achieving insulin independence without tacrolimus in islet transplantation is particularly promising, as it suggests potential superiority over current standard-of-care treatments. With over 90,000 patients awaiting kidney transplants in the US alone, the market opportunity for an effective immunosuppressant that enables both traditional and xenotransplantation is substantial.
Patient treated in procedure, conducted at Mass General Transplant Center and in collaboration with partner eGenesis, was recently released from hospital
Investigational therapy tegoprubart targets CD40 ligand (CD40L) with potential to improve both safety and efficacy compared to standard of care immunosuppression regimens
IRVINE, Calif., Feb. 07, 2025 (GLOBE NEWSWIRE) -- Eledon Pharmaceuticals, Inc. (“Eledon”) (Nasdaq: ELDN) today announced that tegoprubart, the company’s investigational anti-CD40L antibody, was used as a key component of the immunosuppression therapy regimen in a patient who recently received a transplanted kidney from a genetically modified pig. The procedure was performed on January 25, 2025, by surgeons at Massachusetts General Hospital (MGH) in collaboration with our partner eGenesis. In December 2024, MGH received Food and Drug Administration (FDA) approval to proceed with this transplant and plans to perform two additional xenotransplants this year, further advancing the field of xenotransplantation. Following the successful transplant, the patient was discharged from the hospital and is now off dialysis for the first time in over two years.
“This second kidney xenotransplant conducted at MGH represents another important milestone in the effort to consider new strategies in transplantation and immunosuppression to address the global organ shortage crisis. We are grateful to the patient, the team at MGH, and our partner eGenesis for supporting tegoprubart’s central role in these landmark procedures,” said David-Alexandre C. Gros, M.D., Eledon Chief Executive Officer. “Blocking the CD40 Ligand is a critical component of the immunosuppression regimen for effective translation of organ transplant from nonhuman primates into humans. Our anti-CD40L antibody tegoprubart represents a novel approach to immunosuppression therapy with the potential to improve safety and efficacy and enable patients to live longer with their transplanted organs.”
Similar to the first-ever kidney xenotransplant, also conducted at MGH in March 2024, tegoprubart is being administered to the current patient investigationally as part of a regimen designed to prevent the body from rejecting the transplanted pig organ. Tegoprubart is designed to block CD40L and has been shown to inhibit multiple costimulatory receptors including CD40 and CD11, key components of how immune cells communicate with one another. Based on extensive prior research, tegoprubart has been observed to be generally safe and well-tolerated in multiple potential indications, including for the prevention of rejection following kidney allotransplantation.
“I would like to thank Eledon for their work supporting this historic xenotransplant. Immunosuppression presents one of the greatest challenges for transplantation in both human and non-human organs. The need for advancements in immunosuppressive medications is critical for advancing our field and improving the quality of life for transplant patients everywhere,” said Dr. Leonardo Riella, MD, PhD, Medical Director for Kidney Transplantation at Massachusetts General Hospital.
Tegoprubart was also used as a cornerstone component of the chronic immunosuppression regimen administered following the second-ever transplant of a genetically modified heart from a pig to a human, performed at the University of Maryland Medical Center in September 2023. Currently, tegoprubart is being evaluated in three global clinical studies for the prevention of organ rejection in patients receiving kidney transplants and in a separate investigator sponsored trial for the prevention of islet transplant rejection in patients with type 1 diabetes (T1D). Eledon recently announced initial data from this investigator-initiated islet transplant trial, conducted by the research team at the University of Chicago Medicine Transplant Institute, that demonstrated potentially the first human cases of insulin independence achieved using an anti-CD40L monoclonal antibody therapy without the use of tacrolimus, the current standard of care for prevention of transplant rejection.
The Company plans to report updated interim clinical trial from its ongoing Phase 1b and long-term safety and efficacy extension studies in kidney transplant this summer, topline results from its Phase 2 BESTOW kidney transplant trial in the fourth quarter of 2025, and longer-term follow up results from the investigator-led islet transplant clinical trial at UChicago Medicine Transplant Institute later this year.
