Investing in the Future of Precision Medicine

In previous posts on this blog, our scientists have described the current state of precision medicine, particularly how it relates to companion diagnostics (CDx) and immuno-oncology. As an enterprise, we have been focused on this area of medicine essentially from the beginning, more than 20 years ago. LabCorp Diagnostics developed the clinical trials assay and served as the central lab for the testing of HER2-positive breast cancer during the development of trastuzumab. The company provided analytical testing data for the associated immunohistochemistry laboratory test resulting in the first companion diagnostic approved by the FDA. More recently, Covance was instrumental in supporting the drug development efforts for pembrolizumab, the therapy used successfully to treat former President Jimmy Carter’s melanoma, and its associated companion diagnostic.

Precision Medicine in Immuno-Oncology

The NIH defines precision medicine as “an emerging approach for disease treatment and prevention that takes into account individual variability in genes, environment, and lifestyle for each person1.” In cancer patients, we can rephrase the definition to “through detailed understanding of a cancer’s biology, providing the right drug, for the right patient, at the right time.” Covance CRO Labs Blog

In order to identify the correct drug, biomarkers are used to identify patients that can be treated with the appropriate therapy for their cancer. The FDA defines biomarkers as “a defined characteristic that is measured as an indicator of normal biological processes, pathogenic processes, or responses to an exposure or intervention, including therapeutic interventions2.” Great strides have been made in the discovery and validation of biomarkers in drug development.
