Wu00aReimagining human-centric drug development with new approach methodologies uhttps://www.science.org/doi/10.1126/science.aeb0045 aeaeb00450 v03 aDespite unprecedented technological progress, most drug candidates continue to fail in clinical trials, reflecting a persistent gap between preclinical models and human biology. New approach methodologies (NAMs), by spanning human-derived cellular systems, microphysiological platforms, and artificial intelligence, offer a paradigm shift in human-centric drug development and biomedical research. Recent regulatory reforms, such as the US Food and Drug Administration (FDA) Modernization Act 3.0, have begun to position NAMs as a complement to or replacement for animal testing. This Review synthesizes emerging biological and computational NAMs and examines how their integration is reshaping drug development. We also discuss regulatory and ethical frameworks enabling this transition and outline a roadmap for embedding NAMs in a predictive, efficient, and ethically grounded infrastructure of human-centered drug development.
