IRVINE, Calif., Dec. 21, 2022 (GLOBE NEWSWIRE) -- Critical Path Institute (C-Path) announced on December 20, 2022, that its Transplant Therapeutic Consortium (TTC) received a qualification opinion for the iBox Scoring System as a novel secondary efficacy endpoint for kidney transplant clinical trials through the European Medicines Agency’s (EMA) qualification of novel methodologies for drug development. This novel secondary endpoint supports the evaluation of new immunosuppressive therapy (IST) applications for the prevention of kidney transplant rejection and is the first EMA qualified endpoint for any transplant indication.

The iBox Scoring System is a composite endpoint of kidney graft function that utilizes multiple clinical, histological and serum biomarkers for the early prediction of graft failure, including measures of renal function (eGFR and proteinuria) and immunologic response to the graft (donor-specific antibody), with or without direct assessment of allograft health through histopathology (Banff lesion scores). The TTC has been key in advancing the application of the iBox Scoring System from an online assessment of graft function utilized by physicians and researchers to a robust online system now accepted as an efficacy endpoint in clinical trials.

“We are proud to be collaborators with the Transplant Therapeutic Consortium and congratulate it on receiving this important qualification opinion from the EMA,” said David Alexandre C. Gros, M.D., Chief Executive Officer of Eledon. “New ISTs are needed to improve kidney transplant outcomes and extend both allograft function and survival. We look forward to incorporating the iBox Scoring System as an endpoint in our trials, as we continue our development of tegoprubart for the prevention of allograft rejection in patients receiving a kidney transplant.”
