The draft EMA qualification opinion is available for public consultation until November 17, 2022
Secondary endpoint prognostic for allograft loss to catalyze development of novel therapies intended to improve long-term outcomes for kidney transplant recipients
TUCSON, Ariz., Oct. 13, 2022 — Critical Path Institute (C-Path) announced today that its Transplant Therapeutics Consortium (TTC) received a draft qualification opinion for the iBox Scoring System as a novel secondary efficacy endpoint for kidney transplant trials. This was achieved through the European Medicines Agency’s (EMA) qualification of novel methodologies for drug development. After the draft qualification opinion undergoes the public consultation stage through Nov. 17, 2022, the iBox Scoring System will represent the first qualified endpoint for any transplant indication. This novel secondary endpoint supports the evaluation of novel immunosuppressive therapy (IST) applications with EMA.
As stated in the draft qualification opinion, “The CHMP encourages the use of the iBox scoring system as a secondary endpoint in future trials of kidney transplantation and further development of the scoring system targeting a potential future qualification as a surrogate endpoint.”
Although the current efficacy failure endpoint has typically shown the non-inferiority of IST regimens, the iBox Scoring System can be used to demonstrate the superiority of a new IST compared to the standard of care (SOC) at six months up to 24 months post-transplant in pivotal or exploratory drug therapeutic studies. “The ultimate goal is to improve the long-term outcomes in kidney transplant recipients, and this qualification is the first step to enhance development of innovative therapies in kidney transplant,” said Kenneth Newell, M.D., co-leader for TTC’s Efficacy and Endpoints Workgroup.
“Sponsors and investigators can assess and promote the potential advantages and superiority of novel ISTs when measured using the iBox Scoring System. Superiority to current SOC, thereby addressing an unmet need in kidney transplant, is one of the key criteria for Conditional Marketing Authorisation in the EU,” said Ulf Meier-Kriesche, M.D., co-leader for TTC’s Efficacy and Endpoints Workgroup.
The iBox Scoring System is a composite biomarker that utilizes multiple clinically relevant patient features to fully reflect the heterogeneity 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 collaboration with TTC has been instrumental in adapting the iBox Scoring System from a tool in patient-level decision-making to application as an efficacy endpoint in clinical trials,” said Alexandre Loupy, M.D., Ph.D., head and founder of the Paris Transplant Group (INSERM) and professor of Nephrology and Epidemiology at the University of Paris Cité and Assistance Publique-Hôpitaux de Paris.
“In 2017, C-Path created TTC in partnership with the American Society of Transplantation (AST) and the American Society of Transplant Surgeons (ASTS) with a mission to accelerate the medical product development process for transplantation. The qualification of the iBox Scoring System has been TTC’s primary initiative from inception,” said C-Path’s TTC Executive Director, Amanda Klein, Pharm.D. “This monumental achievement would not have been possible without the international transplant community’s ongoing collaboration, data sharing, expertise and dedication.”
This regulatory draft qualification achievement was accomplished by employing the resources of the TTC members and engaging with EMA throughout the qualification process. TTC is supported through funding and input from the American Society of Transplantation, American Society of Transplant Surgeons, argenx, Bristol Myers Squibb, CareDx, CSL Behring, FDA, Hansa Biopharma, Immucor, Natera, National Institute of Health, Novartis, Sanofi, Takeda, Talaris Therapeutics, Thermo Fisher Scientific, The Transplantation Society, Transplant Genomics and Veloxis Pharmaceuticals.
TTC is also working on its next regulatory milestone- the regulatory endorsement of the iBox Scoring System as a reasonably likely surrogate endpoint by the U.S. Food and Drug Administration (FDA), to whom the Qualification Plan has been submitted and is under review by the Agency.
The draft qualification opinion can be found on the EMA website. The draft EMA qualification opinion is now available for public consultation through November 17, 2022.
