Tegoprubart

Completed enrollment in Phase 2 BESTOW trial assessing tegoprubart in kidney transplantation four months ahead of schedule; on track to report topline results in fourth quarter of 2025 Presented updated data on 13 participants from ongoing Phase 1b trial that continue to support safety and tolerability of tegoprubart for prevention of organ rejection in kidney transplantation Announced positive initial data from first three subjects with type 1 diabetes treated with tegoprubart as part of immunosuppression regimen following islet transplantation in investigator-initiated trial at UChicago Medicine Completed two financings totaling $135 million in combined gross proceeds, with funds expected to support operations through end of 2026 IRVINE, Calif., Jan. 13, 2025 (GLOBE NEWSWIRE) -- Eledon Pharmaceuticals, Inc. (“Eledon”) (Nasdaq: ELDN) today announced a summary of 2024 accomplishments and provided guidance for anticipated 2025 business milestones. “2024 was a transformative year for Eledon as we achieved multiple key clinical milestones for tegoprubart across kidney, islet cell, and xenograft transplantation,” said David-Alexandre C. Gros, M.D., Chief Executive Officer of Eledon. “Moreover, the data we reported reinforced the potential of tegoprubart to be a best-in-class immunosuppression therapy to prevent transplant rejection and disrupt the current standard of care. We now look forward to another pivotal year ahead.” 2024 Key Highlights Completed enrollment of 120 patients in the Phase 2 BESTOW clinical trial approximately four months earlier than originally planned. The Phase 2 trial is designed to assess the safety and efficacy of tegoprubart for the prevention of organ rejection in patients undergoing kidney transplantation. Presented updated data at the American Transplant Congress (ATC) from the ongoing Phase 1b open-label trial evaluating tegoprubart for the prevention of organ rejection in kidney transplant patients. Updated data from 13 participants demonstrated that tegoprubart was generally safe and well tolerated, with an overall mean estimated glomerular filtration rate (eGFR) of 70.5 mL/min/1.73m2 at all reported time points after day 30 post-transplant. Two participants completed more than 12 months on therapy post-transplant, and both demonstrated mean eGFRs above 90 mL/min/1.73m2 at one-year post-transplant. Announced positive initial data for the first three islet transplant recipients treated with tegoprubart as part of an immunosuppression regimen for the prevention of islet transplant rejection in subjects with type 1 diabetes in an investigator-initiated trial at the University of Chicago Medicine’s Transplant Institute. The data demonstrated potentially the first human cases of insulin independence achieved using an anti-CD40L monoclonal antibody immunosuppression therapy without the use of tacrolimus, the current standard of care for prevention of transplant rejection. Announced the use of tegoprubart as part of the immunosuppression treatment regimen used following the first-ever kidney xenotransplant procedure of a genetically modified pig kidney to a human. Completed two financings for combined total gross proceeds of $135.0 million, before deducting any offering related expenses, which is anticipated to support company operations to the end of 2026. Anticipated 2025 Milestones Summer 2025: Report updated interim clinical data from the ongoing Phase 1b and long-term efficacy extension studies of tegoprubart in kidney transplantation. 4Q 2025: Report topline results from the Phase 2 BESTOW trial of tegoprubart in kidney transplantation. 2025: Report longer-term follow up results from the investigator-led clinical trial at UChicago Medicine Transplant Institute for pancreatic islet transplantation in subjects with type 1 diabetes involving use of tegoprubart as part of immunosuppression regimen. About Eledon Pharmaceuticals and tegoprubart Eledon Pharmaceuticals, Inc. is a clinical stage biotechnology company that is developing immune-modulating therapies for the management and treatment of life-threatening conditions. The Company’s lead investigational product is tegoprubart, an anti-CD40L antibody with high affinity for the CD40 Ligand, a well-validated biological target that has broad therapeutic potential. 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. The Company is building upon a deep historical knowledge of anti-CD40 Ligand biology to conduct preclinical and clinical studies in kidney allograft transplantation, xenotransplantation, and amyotrophic lateral sclerosis (ALS).

Completed enrollment of Phase 2 BESTOW trial of tegoprubart in kidney transplantation four months ahead of schedule; on track to report topline results in fourth quarter of 2025 Announced positive initial data from first three subjects with type 1 diabetes treated with tegoprubart as part of immunosuppression regimen following islet transplantation in investigator-initiated trial at UChicago Medicine Announced oversubscribed $85 million underwritten offering, with proceeds expected to extend cash runway to the end of 2026 IRVINE, Calif., Nov. 12, 2024 (GLOBE NEWSWIRE) -- Eledon Pharmaceuticals, Inc. (“Eledon”) (Nasdaq: ELDN) today reported its third quarter 2024 operating and financial results and reviewed recent business highlights. “We believe tegoprubart has best-in-class potential as a novel immunosuppressive treatment option to prevent transplant rejection, with promising clinical results across kidney, xenograft, and now islet transplantations," said David-Alexandre C. Gros, M.D., Chief Executive Officer of Eledon. “Recent encouraging data from the UChicago Medicine trial in type 1 diabetes, combined with our accelerated enrollment in the Phase 2 BESTOW trial and our strong capital position following our recent oversubscribed financing, has put us in a strong position to advance tegoprubart’s development. We look forward to sharing results from our BESTOW trial in the fourth quarter of 2025.” Recent Business Highlights Completed enrollment for the Phase 2 BESTOW clinical trial, which is designed to assess the safety and efficacy of tegoprubart for the prevention of organ rejection in patients undergoing kidney transplantation. The trial reached its target enrollment of 120 participants approximately four months earlier than originally planned.Announced positive initial data for the first three islet transplant recipients treated with tegoprubart as part of an immunosuppressive regimen for the prevention of islet transplant rejection in subjects with type 1 diabetes in an investigator-initiated trial at the University of Chicago Medicine’s Transplantation Institute. The first two subjects achieved insulin independence and remain insulin free, with glucose control in the normal range; the third subject was recently transplanted and remains on a trajectory to also achieve insulin independence. Treatment with tegoprubart was generally well tolerated in all subjects with no unexpected adverse events. The data demonstrated potentially the first human cases of insulin independence achieved using an anti-CD40L monoclonal antibody immunosuppressive therapy without the use of tacrolimus, the current standard of care for prevention of transplant rejection.Completed an oversubscribed, underwritten offering of common stock and pre-funded warrants for total gross proceeds of $85.0 million, or net proceeds of approximately $79.5 million after deducting underwriting discounts, commissions, and offering expenses. The offering, which priced at a premium, included participation from both new and existing leading healthcare investors. Anticipated Upcoming Milestones Mid-2025: Report updated interim clinical data from the ongoing Phase 1b and long-term safety and efficacy extension studies of tegoprubart in kidney transplantation.4Q 2025: Report topline results from the Phase 2 BESTOW trial of tegoprubart in kidney transplantation.2025: Report longer-term follow up from the investigator-led clinical trial with the UChicago Medicine Transplant Institute for pancreatic islet transplantation in subjects with type 1 diabetes. Third Quarter 2024 Financial Results Cash, cash equivalents and short-term investments totaled $78.2 million as of September 30, 2024, which does not include net proceeds of approximately $79.5 million received in the October 2024 underwritten offering. The company expects current cash, cash equivalents and short-term investments, together with the net proceeds from the October 2024 underwritten offering, to fund operations to the end of 2026. Research and development (R&D) expenses for the third quarter of 2024 were $16.5 million, compared to $7.9 million for the comparable period in 2023, an increase of $8.6 million. The increase was primarily driven by a rise in clinical development expenses related to the Phase 1b and Phase 2 BESTOW studies, an increase in employee compensation and benefits related to increased headcount, and greater chemistry, manufacturing and controls (CMC) expenses related to the production of clinical trial materials. General and administrative expenses for the third quarter of 2024 were $4.0 million, compared to $3.3 million for the comparable period in 2023, an increase of $0.7 million. The increase was primarily driven by a rise in professional services and an increase in general operating expenses. Net income for the third quarter of 2024 was $77.0 million, or $1.05 per basic share, compared with a net loss of $9.9 million, or $0.33 per basic share, for the comparable period in 2023, an increase of $86.9 million. The increase in net income was primarily driven by a non-cash gain of $96.4 million related to changes in the fair value of warrant liabilities and the fair value of financial instruments issued in excess of proceeds, recorded in the third quarter ending September 30, 2024. Excluding this gain, the company would have recorded a net loss of $19.5 million for the third quarter of 2024.
