The aims of the initiative are to advance biomarker validation through the compilation of data from multiple sources and through a specific pilot project focused on aggregating data for biomarkers of drug-induced kidney injury. The purpose of this notice is to inform the public of the aims of this initiative, to encourage human data submission and sharing, and to identify opportunities to enhance interactions between relevant stakeholders and FDA. The Agency intends to use the information submitted to inform future activities related to data sharing, biomarker development, and broader translation of biomarkers of drug-induced kidney injury."}
