Successful End-of-Phase 2 meeting with FDA supports advancement of tegoprubart into a global Phase 3 kidney transplantation trial, on track to initiate in late 2026
Long-term Phase 2 BESTOW data presented at ATC 2026 demonstrated sustained higher kidney function and improved patient-reported outcomes with tegoprubart compared with tacrolimus
Updated islet cell transplantation data presented at ADA 2026 showed 100% insulin independence in all 12 patients with type 1 diabetes
Cash, cash equivalents and short-term investments of $88.8 million as of June 30, 2026
IRVINE, Calif., Aug. 13, 2026 (GLOBE NEWSWIRE) -- Eledon Pharmaceuticals, Inc. (“Eledon”) (Nasdaq: ELDN) today reported its second quarter 2026 operating and financial results and provided recent business highlights.
“During the first half of the year, we made meaningful progress establishing the regulatory framework for our planned Phase 3 kidney transplantation program, which we expect to initiate later this year,” said David-Alexandre C. Gros, M.D., Chief Executive Officer of Eledon. “The continued strength of our clinical data, including sustained long-term kidney function in BESTOW and the compelling results from the UChicago Medicine islet cell transplantation study, reinforces the potential of tegoprubart to improve outcomes across multiple transplant settings. We look forward to advancing our Phase 3 program and expanding the clinical evidence for tegoprubart across additional transplant indications.”
Second Quarter 2026 Business Highlights
Kidney Transplantation
- Completed a successful End-of-Phase 2 meeting with the U.S. Food and Drug Administration, establishing the regulatory framework for the planned Phase 3 trial of tegoprubart in kidney transplantation. The global trial is on track to initiate in late 2026 and enroll approximately 600 patients, with a primary endpoint of non-inferiority versus tacrolimus at 52 weeks based on a composite of biopsy-proven acute rejection (BPAR), graft loss and death.
- Presented new long-term data from the Phase 2 BESTOW clinical program at the American Transplant Congress (ATC) in June 2026, demonstrating sustained higher kidney function in kidney transplant patients treated with tegoprubart compared with tacrolimus, the current standard-of-care immunosuppression therapy. At 18 months, the eGFR curves showed a statistically significant separation (p<0.05), with mean eGFR approximately 12 mL/min/1.73 m² higher for tegoprubart compared with tacrolimus (approximately 74 vs. 61 mL/min/1.73 m²). No 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. Long-term data from the BESTOW extension trial also demonstrated favorable long-term safety and tolerability.
- Treated the first two patients in an investigator-initiated study of kidney transplant tolerance induction at Massachusetts General Hospital.
- Entered into a strategic partnership with Natera, Inc., a global leader in cell-free DNA testing and precision medicine, to incorporate Natera’s Prospera kidney transplant assessment test as the exclusive donor-derived cell-free DNA (dd-cfDNA) monitoring assay in Eledon’s planned Phase 3 kidney transplantation trial.
Islet Cell Transplantation
- Presented updated data from the University of Chicago Medicine investigator-initiated islet cell transplantation study at ADA 2026. All 12 patients with T1D achieved insulin independence and HbA1c below 6.5%, with a mean most recent HbA1c of approximately 5.4% and no severe hypoglycemic episodes post-transplant. Tegoprubart demonstrated stable islet graft function through a maximum follow-up of 22 months and was generally well tolerated, with no evidence of nephrotoxicity, hypertension or neurotoxicity.
Anticipated Upcoming Milestones
The Company anticipates the following milestones in 2026 and over the next 12 months:
- Initiate Phase 3 clinical trial evaluating tegoprubart in kidney transplantation in late 2026.
- Support the initiation of an investigator-led study evaluating tegoprubart for the prevention of organ rejection in patients with renal dysfunction receiving an islet cell transplant in 2026.
- Initiate company-sponsored, registration path study evaluating tegoprubart in islet cell transplantation.
- Support the initiation of an investigator-led study evaluating tegoprubart for the prevention of organ rejection in patients receiving a de novo liver transplant.
- Receive FDA regulatory guidance on the path to market for tegoprubart in xenotransplantation.
Second Quarter 2026 Financial Results
Cash, cash equivalents and short-term investments totaled $88.8 million as of June 30, 2026, compared to $133.3 million as of December 31, 2025. The Company expects current cash, cash equivalents and short-term investments to fund operations into the second quarter of 2027.
Research and development (R&D) expenses for the second quarter of 2026 were $18.2 million, including $2.1 million of non-cash stock-based compensation expense, compared to $20.3 million for the comparable period in 2025, including $1.1 million of non-cash stock-based compensation expense.
General and administrative (G&A) expenses for the second quarter of 2026 were $4.6 million, including $1.1 million of non-cash stock-based compensation expense, compared to $4.5 million for the comparable period in 2025, including $1.6 million of non-cash stock-based compensation expense.
Net loss for the second quarter of 2026 was $31.6 million, or $0.27 per basic common share, compared to a net loss of $11.2 million, or $0.13 per basic common share, for the comparable period in 2025. Net loss in the second quarter of 2026 included a non-cash loss of $9.6 million from changes in the fair value of warrant liabilities, while the 2025 net loss included a non-cash gain of $12.3 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 $22.0 million for the three months ended June 30, 2026, and $23.5 million for the three months ended June 30, 2025.
