Kidney Biomarker Submissions

Following several years of extensive work and collaboration between 16 member companies & the Critical Path Institute’s PSTC leadership, the FDA (US Food and Drug Administration), EMA (European Medicines Agency) and PMDA (the Japanese Pharmaceuticals and Medical Devices Agency) have each qualified seven novel laboratory tests on urine which signal kidney injury. A first for both agencies, the FDA and EMA jointly announced qualification in May 2008. In May 2010, PMDA announced the first ever biomarker qualification decision under PMDA’s new consultation process on pharmacogenomics/biomarkers for use in Japan. The biomarkers were evaluated in data from rat studies submitted to the regulatory agencies by the PSTC. The newly accepted biomarkers are KIM-1, Albumin, Total Protein, B2-Microglobulin, Cystatin C, Clusterin and Trefoil factor-3.

In reviewing the kidney qualification data, the regulatory agencies (FDA, EMA and PMDA) came to the conclusion that:

• • the kidney biomarkers are acceptable in the context of non-clinical drug development for the detection of acute drug-induced kidney toxicity;

• • the kidney biomarkers provide additional and complementary information to the currently available standards;

• • the use of kidney biomarkers in clinical trials is to be considered on a case-by-case basis in order to gather further data to qualify their usefulness in monitoring drug-induced kidney toxicity in humans.

• PSTC is actively involved in research to further qualify biomarkers for use in clinical drug development.
