The discovery, development, and use of biomarkers for a variety of drug development purposes are areas of tremendous interest and need. Biomarkers can become accepted for use through submission of biomarker data during the drug approval process. Another emerging pathway for acceptance of biomarkers is via the biomarker qualification program developed by the Center for Drug Evaluation and Research (CDER, US Food and Drug Administration). Evidentiary standards are needed to develop and evaluate various types of biomarkers for their intended use and multiple stakeholders, including academia, industry, government, and consortia must work together to help develop this evidence. The article describes various types of biomarkers that can be useful in drug development and evidentiary considerations that are important for qualification. A path forward for coordinating efforts to identify and explore needed biomarkers is proposed for consideration., (© 2015 American Society for Clinical Pharmacology and Therapeutics.)

The US Food and Drug Administration (FDA) has directed considerable effort towards modernizing its regulatory processes over the past decade to address the challenges in the drug development sector. Through partnerships and input from stakeholders, multiple initiatives are under way, many projects have been launched, several have resulted in tangible results, and many are ongoing and under discussion. We are learning that collaborative efforts can better inform and leverage existing knowledge, that the challenges of data sharing and intellectual property can be overcome, and that there is wide interest in partnering to address key public health regulatory science issues. It is crucial that we continue to build on these initial efforts to facilitate drug development., (© 2015 American Society for Clinical Pharmacology and Therapeutics.)
