The National Kidney Foundation is collaborating with the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) to host a scientific workshop to evaluate alternative endpoints for clinical trials in the early stages of CKD. An integral part of the initiative, now underway, is an extensive meta-analysis of existing data from both interventional clinical trials and observational cohort data to evaluate changes in albuminuria (or proteinuria), the rate of GFR decline, and combinations of both strategies, as predictors of kidney disease progression, kidney failure and other adverse clinical outcomes.
The analysis and conference will expand on prior studies of albuminuria as a surrogate endpoint, and address outstanding questions about the use of albuminuria as a surrogate endpoint, particularly in early stages of CKD.1-7 In addition, the analysis and conference will build on the 2012 NKF-FDA Workshop, "GFR Decline as an End Point in Clinical Trials in CKD" that showed strong relationships between change in eGFR and kidney failure and mortality in observational studies and in past clinical trials.8-12 Finally, the conference will explore how combinations of these endpoints might be useful, in clinical practice as well as clinical trials.
Following the workshop, to be held in the Washington, DC area on March 15-16, 2018, there will be a series of publications reporting on the workshop deliberations and the results of pre-workshop data analyses and trial simulations being conducted by investigators at Johns Hopkins University, Tufts University, the University of Utah, and Groningen University.
