Abstract

A key aspect of in vitro-to-in vivo extrapolation (IVIVE) linked to physiologically based pharmacokinetic (PBPK) modelling (IVIVE-PBPK) is ensuring that input data derived from in vitro assays intrinsically reflect the compound's true properties, free from the confounding effects of assay design, model structure, or data transformation methods. Having assurance in the model inputs provides an incr…
