Two of the kidney transplant recipients remains alive with ongoing graft function.
Current report
General and administrative expenses increased by $0.1 million for the three months ended June 30, 2025, compared to the three months ended June 30, 2024. The decrease was primarily attributable to the following:

Eledon is a clinical stage biotechnology company using our immunology expertise in targeting the CD40 Ligand (“CD40L”) pathway to develop therapies to protect transplanted organs and prevent rejection, and to treat amyotrophic lateral sclerosis (“ALS”). Our lead compound in development is tegoprubart, an IgG1, anti-CD40L antibody with high affinity for the CD40 Ligand, a well-validated biological target that we believe has broad therapeutic potential. We believe 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.

In July 2022, we received Investigational New Drug (“IND”) application clearance from the FDA for our controlled, Phase 2 BESTOW trial of tegoprubart for the prevention of transplant rejection in persons receiving a kidney transplant. The BESTOW study is a multi-center, two-arm, active comparator, head-to-head superiority clinical study, and will enroll approximately 120 participants undergoing kidney transplantation in the U.S. and other countries to evaluate the safety, pharmacokinetics, and efficacy of tegoprubart compared to the calcineurin inhibitor tacrolimus. The study’s primary objective is to assess graft function as measured by estimated eGFR at 12 months post-transplant in participants treated with tegoprubart compared to tacrolimus. Secondary objectives will include assessment of graft survival, biopsy-proven acute rejection, and the incidence of new onset diabetes mellitus after transplant. The BESTOW study is running in parallel to the ongoing Phase 1b clinical trial of tegoprubart in kidney transplantation. The first subject in the BESTOW study was dosed in August 2023. On September 4, 2024, we announced the completion of enrollment in the BESTOW study.

In January 2024, we announced that tegoprubart would be utilized in an investigator-initiated trial, conducted at the University of Chicago Medicine's Transplantation Institute. This pilot study is assessing the safety of using a monoclonal antibody against CD40 Ligand to achieve a calcineurin inhibitor-free immunosuppression regimen in patients with T1D mellitus undergoing islet cell transplantation. The Company is not funding this trial but is providing tegoprubart for use in the study.

On October 29, 2024, positive data were reported for the first three islet transplant recipients in the study, potentially demonstrating the first human cases of insulin independence achieved using an anti-CD40L monoclonal antibody therapy without the use of tacrolimus. The first two subjects achieved insulin independence and normal hemoglobin A1C (HbA1c) levels, a measure of average blood glucose, post-transplant. The third subject, decreased insulin use by more than 60% three days following the procedure and continues on insulin independence trajectory typically observed one-to-two months post-transplant. Subjects in the study received islet transplants combined with induction therapy and for chronic maintenance therapy, mycophenolate mofetil plus tegoprubart given every third week by intravenous infusion. The first two subjects achieved insulin independence and presented stable islet graft function at approximately three months and six months post-transplant, respectively. Islet engraftment, measured by graft function standardized to the number of islets infused, was three to five times higher than three comparable subjects who received tacrolimus-based immunosuppression, suggesting treatment with tegoprubart results is less toxic to transplanted islet cells resulting in improved graft survival and function. Treatment was generally well tolerated in all subjects with no unexpected adverse events or hypoglycemic episodes. After initial islet transplant, the first participant reduced insulin requirements by over 60% and normalized blood glucose control. As of October 29, 2024, the first patient had achieved insulin independence within approximately a week after a second islet transplantation procedure.

In July 2025, updated data were presented for the three islet transplant recipients enrolled in the study. All three patients achieved stable islet graft function, improved blood glucose control, and insulin independence. Islet engraftment in these participants were two to three times higher than that observed in comparable historical patients treated with tacrolimus. Tegoprubart was generally well-tolerated, with no severe hypoglycemic episodes, infections, hypertension, cases of nephrotoxicity or neurotoxicity, or signs of rejection observed to date. An additional six patients are expected to be enrolled in the ongoing study by the end of 2025.

Change in fair value of warrant liabilities and fair value of financial instruments issued in excess of proceeds represents the initial recognition of warrant liabilities at fair value in excess of proceeds received, as well as subsequent period remeasurements of these warrant liabilities at fair value. These remeasurements reflect changes in market conditions, such as fluctuations in stock price, volatility, interest rates, and other valuation inputs that impact the fair value of the liability.

Conditions in the financial and credit markets may also limit the availability of funding or increase the cost of funding. As a result of any of the foregoing factors, adequate additional funding may not be available to us on acceptable terms on a timely basis, or at all. The severity and duration of any such impacts cannot be predicted. Any such failure to raise capital as and when needed could have a negative impact on our financial condition and on our ability to pursue our business plans and strategies or cause us to delay our clinical development plans, research and development programs or commercialization efforts, out-license intellectual property rights to our product candidates or sell unsecured assets, or a combination of the above. Any of these actions could materially harm our business. The issuance of shares of common stock in the 2023 Private Placement, the 2024 Private Placement and the 2024 Underwritten Offering diluted the ownership interests of our existing stockholders, and to the extent that we raise additional capital through the sale of additional equity, including through our “at the market” equity offering program, or convertible debt securities in the future, our stockholders’ ownership interests may be further diluted, and the terms of these securities may also include liquidation or other preferences that adversely affect our stockholders’ rights. Debt financing, if available, would result in fixed payment obligations and may involve agreements that include restrictive covenants that limit our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends, that could adversely impact our ability to conduct our business. If we raise funds through collaborations, licenses and other similar arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us.
