About FDA
Office of Clinical Pharmacology (OCP)
The mission of the Office of Clinical Pharmacology (OCP) is to assure the safety and effectiveness of new drugs through the evaluation of clinical pharmacology and biopharmaceutics data in support of the Center for Drug Evaluation and Research's Investigational New Drug (IND), New Drug Application (NDA), and Biologics License Application (BLA) review programs. Through research, we assure that regulatory policy and decision making are based on the best available science.
What We Do
- Evaluate what the body does to the drug and what the drug does to the body
- Understand inter-patient variabilities that relate to benefit and risk
- Optimize dose and dose regimen to balance benefit and risk
- Translate knowledge from NDA/BLA reviews into labeling language that is understandable and actionable
- Conduct research to expand our knowledge of clinical pharmacology to better evaluate benefit and risk
