To prevent adverse drug reactions in the post-marketing phase, therapeutic drug monitoring and various laboratory tests have been used for decades. Recently, data on associations between drug adverse reactions and biomarkers based on “omics” technologies/studies have been increasing. Using genomic biomarkers, patients at high risk for developing side effects can be distinguished before initiating medical treatment, allowing the choice of an appropriate drug/initial dosage regimen. Biomarkers based on proteomics or metabolomics can detect the onset of adverse reactions at an earlier stage than can be accomplished with classical laboratory tests. However, the clinical use of drug safety-related biomarkers is still limited compared with biomarkers that predict drug efficacy of, for example, molecular-targeted drugs. In this symposium, genomic biomarkers associated with the safety of anticancer drugs and idiosyncratic adverse reactions are introduced and compared between Japan and other countries. Prospective studies evaluating the application of screening tests to prevent adverse drug reactions are also shown, and steps necessary to accelerate the use of drug safety-related biomarkers are discussed.
