A prototypical process for creating evidentiary standards for biomarkers and diagnostics

A framework for developing evidentiary standards for qualification of biomarkers is a key need identified in the Food and Drug Administration's Critical Path Initiative. 1 This article describes a systematic framework that was developed by Pharmaceutical Research and Manufacturers of America (PhRMA) committees and tested at a workshop in collaboration with the Food and Drug Administration and academia. With some necessary refinements, this could be applied to create an appropriately individualized evidentiary standard for any biomarker purpose.
