This talk will introduce the application of Physiologically-Based Pharmacokinetic (PBPK) absorption modeling to evaluate the impact of food on absorption and pharmacokinetics from an industry perspective. The goal of the presentation is to share the experiences from IQ Food Effect PBPK Working Group and drug developers on how to use in silico approaches to predict the impact of food on relative bioavailability and support drug product development. Within the pharmaceutical industry, significant resources are invested to predict and characterize a clinically relevant food effect. Given the complex nature of food effect, an integrated approach is required, and physiologically based absorption models have emerged as a key platform to support food effect predictions. This talk will highlight cases where high and moderate, vs. low confidence is expected in predicting food effect using a novel consistent, prospective approach, in contrast to previous retrospective analyses. Additionally, this talk also aims to provide an aligned approach to model development and validation for food effect, as well as an industry perspective on cases where modeling may be used in lieu of clinical studies. This presentation will shed light on understanding prediction success of food effect and its correlation with the mechanisms driving this effect.
Learning Objectives:
leverage knowledge learned in the symposium to help understand and identify cases that may have high risks of food impact on relative bioavailability and bioequivalence
learn the scientific advances in the use of Physiologically-Based Pharmacokinetic (PBPK) modeling approaches to quantitively predict the impact of food on relative bioavailability and bioequivalence
know challenges of implementing these approaches in assessing the impact of food on the relative bioavailability and bioequivalence for investigational drugs
understand the scientific gaps that preclude the prospective prediction of the effect of food on oral absorption of drugs
identify opportunities to improve the science to enable prediction of effect of food on oral absorption
