WebPharmacodynamic endpoints are outcome measures that allow capture of the potential clinical benefit of a medicinal product. An endpoint may be a quantitative measurement representing a specific parameter, a binary clinical outcome indicating whether an event has occurred, or a time to occurrence of an event of interest. WebPharmacodynamic models describe how a drug affects the body by linking the drug concentration to an efficacy (or safety) metric. A well-characterized PK/PD model is an important tool in guiding the design of future experiments and trials.
