Today, more than ever before, pharmaceutical and biotechnology companies are required to demonstrate the value of their products in an increasingly competitive commercial marketplace. The use of biomarkers provides an excellent opportunity to optimize therapy selection and demonstrate a compelling value proposition to economic stakeholders. Companies that anticipate the potential economic benefits associated with the use of biomarkers improve the likelihood of demonstrating commercial value to payers and providers, and thus improve the commercial potential of their products by optimizing product utilization - getting the right therapy to the right patient at the right time - to improve the balance of risk and benefit. Whether in preclinical or Phase III, biomarkers can help increase the speed, cost, and quality of any drug development program. In early drug development, biomarkers help identify early toxicological effects. During late stage clinical trials, they help prove drug safety and efficacy, guide trial design, and support critical development decisions. As a result of their proven utility and future promise, biomarkers are being increasingly embraced by the medical, regulatory, and payor communities.
