Biomarkers can provide insights into experimental therapies, identify patients who are likely to benefit from them, and improve chances for clinical success. Charles River Laboratories offers a range of early biomarker discovery services, leveraging the expertise of its scientists to identify biomarkers in the early stages of drug development programs. We spoke to Stefan Kostense, director of biology at Charles River Laboratories, about the benefits of conducting biomarker discovery early in the drug development process, how it can drive development decisions in the preclinical phase and beyond, and how it benefits patients.
