The recent approval by the Japanese Pharmaceuticals and Medical Devices Agency (PMDA) of the 7 protein biomarker panel for use in detecting drug-induced kidney damage means that the biomarkers are now qualified at the same level by all of the ICH regulatory agencies.  In a Critical Path Initiative statement, this is the first biomarker qualification decision by the PMDA and means that the panel is qualified for voluntary use in nonclinical safety studies.  Furthermore, data generated using the panel can be submitted to the PMDA on a case-by-case basis for use in monitoring drug-induced renal toxicity in humans.  The 7 biomarker panel,  composed of kidney injury molecule-1, albumin, total protein, β2-microglobulin, cystatin C, clusterin, and trefoil factor 3, can be utilized in conjuntion with the current standard renal biomarkers, serum creatine and blood-urea nitrogen.  With the exception of trefoil factor 3, the PMDA stated that the new renal biomarkers outperformed the current standard biomarkers.  The renal biomarker panel received approval in 2008 from the US Food and Drug Administration (FDA) and the European Medicines Agency (EMEA) for limited use in nonclinical and clinical drug development.  Additional guidelines regarding biomarker qualification are expected in July 2010.
