Office of Clinical Pharmacology


The mission of the Office of Clinical Pharmacology is two-fold: 1) play a pivotal role in advancing development of innovative new medicines by applying state-of-the-art scientific principles; and 2) promote therapeutic optimization and individualization through best practices in research, policy development, and drug evaluation throughout the product lifecycle.

What We Do

  • Generate, evaluate, and use knowledge of drug disposition, pharmacology, and disease biology to progressively reduce regulatory uncertainty and inform public health decision-making;
  • Employ mechanistic and model-informed drug development (MIDD) strategies to maximize the value of early and late phase clinical drug development;
  • Use experimental and analytical approaches to identify, account for, and ultimately predict patient variability in drug responses;
  • Promote therapeutic individualization and personalized medicine by translating knowledge of patient diversity into clinical recommendations for safe and effective drug use; and
  • Conduct research to address immediate and emerging regulatory science issues that impact the development, evaluation, and utilization of new therapeutic products.
