• Agreement leverages Eledon’s investigational anti-CD40L antibody, tegoprubart, as part of eGenesis’ immunosuppression regimen that prevents xenotransplant rejection in nonhuman primate recipients
  
• Establishes framework for use of tegoprubart for preclinical xenotransplantation studies in support of eGenesis’ kidney, heart and islet cell programs

CAMBRIDGE, Mass. and IRVINE, Calif., Jan. 09, 2023 (GLOBE NEWSWIRE) -- eGenesis, Inc. (“eGenesis”) and Eledon Pharmaceuticals, Inc. (“Eledon”) (NASDAQ: ELDN), today announced that they have entered into a collaborative research agreement under which eGenesis will gain access to Eledon’s anti-CD40L antibody candidate, tegoprubart, for eGenesis’ ongoing preclinical research and development studies of human-compatible organs and cells for the treatment of organ failure. The collaboration has the potential to span multiple eGenesis programs including kidney, heart and islet cell transplant.

“Despite significant recent progress and momentum in the field of xenotransplantation, improving organ compatibility to prevent rejection remains an ongoing challenge,” said Michael Curtis, Ph.D., Chief Executive Officer of eGenesis. “This collaboration agreement provides eGenesis with access to tegoprubart, an anti-CD40L immune modulating therapy that we believe may be a critical part of an effective immunosuppression regimen for our ongoing and future preclinical studies and could help position us to achieve successful clinical translation into humans.”

“We are excited to partner with eGenesis in support of our combined commitment to offer effective solutions for patients requiring organ or cellular transplantation,” said David-Alexandre C. Gros, M.D., Chief Executive Officer of Eledon. “We believe this strategic agreement offers a promising step towards helping xenotransplantation become a clinical reality.”

Tegoprubart (formerly known as AT-1501) is an investigational, humanized IgG1 anti-CD40L antibody with high affinity for the CD40 ligand (CD40L, also called CD154). CD40L is an attractive drug development target for transplant immunomodulation since the engagement of the CD40L plays a pivotal role in immune system activation by mediating both antibody and cellular immune responses. Eledon is conducting an international Phase 1b study evaluating tegoprubart for the prevention of rejection in transplant patients receiving a kidney allograft, and recently announced FDA clearance of an IND application to evaluate tegoprubart, in a larger phase 2 study, for the prevention of rejection in patients receiving a kidney allograft transplant.

About Transplantation and Xenotransplantation

Organ failure is a life-threatening condition for which transplantation is considered to be the gold standard treatment. However, the growing demand for organs far outstrips supply – of the more than 100,000 individuals on the organ transplantation waitlist in the U.S., less than 40% will receive a potentially life-saving organ. In addition, the existing organ failure treatment paradigm is suboptimal for patients and the healthcare system due to organ incompatibility and variable donor organ quality.

Xenotransplantation – the transplantation of cells, tissues, and organs from one species to another – is widely viewed by the transplant community to be a viable solution to address the organ shortage crisis. The advent of cutting-edge gene editing technologies, such as CRISPR, has enabled scientists to address the virologic and immunologic hurdles that have historically prevented the advancement of xenotransplantation.
