The aim of this article is to provide a framework to facilitate apposite human PK and dose predictions as a continuum during drug discovery. Firstly, for early Dose Estimation to guide compound design, accelerate decision-making and focus strategy, a simple PK model is proposed based on achieving and maintaining average steady-state concentrations (Css,av) related to a measure of efficacious concentration. A toolbox of methods for the prediction of PK parameters is provided with consideration of the appropriate and effective use. Finally, advances in the understanding of compound properties and TPP will inform model selection for dose projection.
