*FDA Orphan Drug designation granted to tegoprubart for the prevention of allograft rejection in liver transplantation*

*Cash, cash equivalents and short-term investments totaled $111.1 million as of March 31, 2026*

IRVINE, Calif., May 13, 2026 (GLOBE NEWSWIRE) -- Eledon Pharmaceuticals, Inc. ("Eledon") (Nasdaq: ELDN) today reported its first quarter 2026 operating and financial results and provided recent business highlights.

Gros, M.D., Chief Executive Officer of Eledon. "Looking ahead, we expect multiple catalysts in 2026, including regulatory engagements supporting the advancement of tegoprubart into Phase 3 development in kidney transplantation and discussions regarding potential paths to market in islet cell transplantation. We also plan to initiate several new clinical trials, including an investigator sponsored study in liver transplantation, and share new kidney transplant data from our Phase 2 BESTOW long-term extension study, building on encouraging 24-month Phase 1b results that demonstrated a durable safety profile and improved graft function."

**First Quarter 2026 and Business Highlights**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•In March 2026, announced updated results from an ongoing investigator-led trial at the University of Chicago Medicine Transplant Institute evaluating tegoprubart in 12 adults with high-risk type 1 diabetes undergoing allogenic islet transplantation. All 10 patients who are more than four weeks post-transplant achieved 100% insulin independence. There were no signs of graft rejection or de novo donor-specific HLA antibodies and no evidence of nephrotoxicity, hypertension, or neurotoxicity, which are commonly associated with tacrolimus-based immunosuppression regimens, the current standard of care.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The U.S. Food and Drug Administration (FDA) granted Orphan Drug designation to tegoprubart for the prevention of allograft rejection in liver transplantation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Presented 24-month follow-up data from eight patients enrolled in the Phase 1b trial long-term extension trial evaluating tegoprubart in kidney transplantation at the American Society of
