Data from Phase 2 BESTOW trial demonstrated a favorable safety and tolerability profile, substantially reducing the metabolic, neurologic, and cardiovascular toxicities commonly associated with tacrolimus
Data supports advancement into Phase 3 development as a potential new standard for the prevention of kidney transplant rejection
Strengthened balance sheet with $57.5 million financing to advance transplantation programs
IRVINE, Calif., Nov. 14, 2025 (GLOBE NEWSWIRE) -- Eledon Pharmaceuticals, Inc. (“Eledon”) (Nasdaq: ELDN) today reported its third quarter 2025 operating and financial results and reviewed recent business highlights.
“The results from our Phase 2 BESTOW trial demonstrated tegoprubart’s excellent efficacy and safety, importantly avoiding many of the long-term toxicities commonly seen with current standard-of-care immunosuppressive therapies,” said David-Alexandre C. Gros, M.D., Chief Executive Officer of Eledon. “Further, the proceeds from our recent financing enhance our ability to advance tegoprubart’s programs in kidney transplantation, islet cell transplantation, and xenotransplantation, addressing critical unmet needs in transplant medicine.”
Third Quarter 2025 and Business Highlights
- Presented results from the Phase 2 BESTOW trial evaluating tegoprubart for the prevention of organ rejection in patients receiving a kidney transplant at the American Society of Nephrology’s Kidney Week 2025 Annual Meeting in Houston, TX. Tegoprubart demonstrated a favorable safety and tolerability profile, substantially reducing the metabolic, neurologic, and cardiovascular toxicities commonly associated with tacrolimus. Kidney function, as measured by estimated glomerular filtration rate (eGFR), was approximately 69 mL/min/1.732 at 12-months for participants in the tegoprubart treatment arm (n=51).
- Based on the Phase 2 BESTOW results, Eledon plans to advance tegoprubart into Phase 3 development following discussions with regulators on study design and data requirements. Insights from the Phase 2 BESTOW data set and the ongoing long-term extension study will be incorporated to optimize the Phase 3 protocol and strengthen the regulatory package.
- On November 13, 2025, Eledon completed an underwritten public offering of common stock and pre-funded warrants, resulting in total gross proceeds of $57.5 million and net proceeds of approximately $53.6 million after deducting underwriting discounts, commissions, and estimated offering expenses.
Anticipated Upcoming YE2025 and 2026 Milestones
- 4Q 2025: Enroll final three patients with Type 1 diabetes in the investigator-led clinical study at UChicago Medicine evaluating tegoprubart in islet cell transplantation.
- 2026: Receive U.S. Food & Drug Administration (“FDA”) guidance on the Phase 3 trial design for kidney transplantation, and subsequently initiate a Phase 3 trial in kidney transplantation.
- 2026: Report long-term data from the Phase 1 and Phase 2 BESTOW studies in kidney transplantation.
- 2026: Report data from nine patients in the investigator-led islet cell transplantation study.
- 2026: Receive FDA regulatory guidance on path to market for islet cell transplantation & xenotransplantation.
Third Quarter 2025 Financial Results
Cash, cash equivalents and short-term investments totaled $93.4 million as of September 30, 2025 compared to $140.2 million as of December 31, 2024.
Research and development (R&D) expenses for the third quarter of 2025 were $15.0 million, including $1.1 million of non-cash stock-based compensation expense, compared to $16.5 million, including $0.4 million of non-cash stock-based compensation expense, for the comparable period in 2024.
General and administrative expenses for the third quarter of 2025 were $4.1 million, including $1.4 million of non-cash stock-based compensation expense, compared to $4.0 million, including $1.4 million of non-cash stock-based compensation expense, for the comparable period in 2024.
Net loss for the third quarter of 2025 was $17.5 million, or $0.21 per basic common share, compared to a net income of $77.0 million, or $1.05 per basic common share, for the comparable period in 2024. Net income in the third quarter of 2024 included a non-cash gain of $96.4 million related to changes in the fair value of warrant liabilities. Excluding this non-cash gain, Eledon would have recorded a net loss of $19.5 million for the third quarter of 2024.
