PK/PD modelling and simulations: utility in drug development

Pharmacokinetic/pharmacodynamic (PK/PD) modelling and simulation can be used as an 'applied science' tool to provide answers on efficacy and safety of new drugs faster and at a lower cost. PK/PD modelling can be used from the preclinical phase through all clinical phases of drug development. Optimal use of PK/PD modelling and simulation will lead to fewer failed compounds, fewer study failures and smaller numbers of studies needed for registration. For PK/PD modelling to fulfil its potential in drug development, it needs to be embraced across the industry and regulatory agencies, and more education on this topic is required.
