False positives in in vitro toxicology and drug-drug interaction (DDI) studies remain a major bottleneck in drug development, leading to unnecessary clinical trials, inflated costs and delayed access to life saving therapies. However, recent advances in transporter science - including validation of biomarkers like coproporphyrin I (CPI) and next generation in vitro models such as organ on a chip, combined with modelling techniques - are transforming the landscape, enabling more accurate prediction of toxicity and DDI scenarios
This whitepaper explores the latest advances in transporter science and modelling techniques, providing practical guidance for drug developers on integrating biomarker and assay data to improve predictive reliability, in alignment with ICH M12 regulatory guidelines.
