The use of biomarkers has long held the promise accelerating drug development and producing safer and more targeted drugs to meet the needs of patients. The explosion of genetic, proteomic, and metabolomic data, as well as the emergence of the human microbiome, is rapidly growing the world of biomarkers, but with that comes challenges for researchers and drug developers about knowing what’s available and how well validated these biomarkers may be. We spoke to John Audette, president and co-founder of Amplion, about the company’s database, which seeks to make biomarker information accessible to researchers, the role biomarkers can play in improving the drug development process, and how their increased use can bring about a long anticipated era of precision medicine.
