Should l Buy ELDN?
Eledon Pharmaceuticals announced that the U.S. Food and Drug Administration, FDA, has granted Orphan Drug designation, ODD, to tegoprubart for the prevention of allograft rejection in liver transplantation. "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."

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.
