Preclinical biomarker qualification.

Biomarkers are ubiquitously used within drug development programs in both nonclinical species and in humans to assess safety and efficacy of novel compounds. To routinely apply such novel biomarkers with certainty, a well-defined data package is necessary for review and endorsement by regulatory agencies including the US Food and Drug Administration, European Medicines Agency, and Japanese Pharmaceuticals and Medical Devices Agency. This type of endorsement is known as regulatory qualification. Novel approaches are being applied to speed the process, lower the resource intensity, and increase the accessibility of biomarker qualification data and it is likely that consortia will continue to play a fundamental role in the qualification process by bringing together like-minded stakeholders focused on specific tools to accelerate drug development. This article will focus on learnings from the previous three nonclinical biomarker qualification projects, as well as discuss the progression of preclinical biomarker projects into the clinical qualification space and the current strategy for the use of nonclinical biomarker data in the translational qualification of clinical biomarkers; much like nonclinical information is used in the approval of drug development candidates. Impact statement This minireview provides an overview of the history of preclinical biomarker qualification by summarizing the three examples of this type of qualification with US Food and Drug Administration, European Medicines Agency, and Japanese Pharmaceuticals and Medical Devices Agency. In addition, an overview of the biomarker qualification process is included to educate key stakeholders with links to relevant white papers that provide information on current evidentiary considerations. The manuscript also provides new information on the evolution of the role that preclinical qualification plays in clinical qualification of biomarkers and the novel approaches that are being utilized to improve the process.
