One of the areas of FDA’s focus from the Critical Path Initiative has been the creation of Drug Development Tools (DDTs), which are methods, materials, or measures that have the potential to facilitate drug development¹. FDA created a formal qualification program to support the evaluation of some of these DDTs in areas where C-Path is working including biomarkers and clinical outcome assessments. Through this program, submitters of DDTs refine the tools and submit them for a qualification assessment.
A summary of C-Path’s progress-to-date is depicted in the tables below and represent three distinct categories: Qualified Biomarkers, Biomarker Submissions and Letters of Support that have been issued for certain biomarkers that are not qualified but warrant further evaluation.
