- Significant Kidney Function Improvement: At 18 months, the mean eGFR for patients treated with Tegoprubart was 74 mL/min/1.73 m², showing a statistically significant advantage of approximately 12 mL/min/1.73 m² over the 61 mL/min/1.73 m² in the Tacrolimus group, indicating its potential to redefine standards in transplant immunomodulation.
- Zero Rejection Events: No biopsy-proven acute rejection (BPAR) events were observed in Tegoprubart-treated patients after six months, compared to seven events (approximately 9.4%) in the Tacrolimus arm, highlighting Tegoprubart's advantage in reducing rejection risks and potentially improving long-term transplant outcomes.
- Improved Patient-Reported Outcomes: At 52 weeks, Tegoprubart-treated patients reported significantly lower symptom burden on two validated measures compared to those on Tacrolimus, indicating enhanced quality of life, which is crucial for meeting the long-term needs of kidney transplant recipients.
- Next Steps in Development: Eledon plans to initiate Phase 3 clinical development of Tegoprubart by late 2026, with the primary endpoint being non-inferiority to Tacrolimus at 52 weeks, leveraging key insights from the BESTOW trial to further validate its clinical advantages.

About ELDN
Eledon Pharmaceuticals, Inc. is a clinical-stage biopharmaceutical company. The Company is developing immune-modulating therapies for the management and treatment of life-threatening conditions. The Company’s lead investigational product is tegoprubart, an IgG1, 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. Tegoprubart is engineered to potentially both improve safety and provides pharmacokinetic, pharmacodynamic, and dosing advantages. CD40L is primarily expressed on activated CD4+ T cells, platelets, and endothelial cells while the CD40 receptor is constitutively expressed on antigen-presenting cells, such as macrophages and dendritic cells, as well as B cells.
