Parikh00aAdvancing FDA New Approach Methodologies from animal models through digital twins uhttps://www.nature.com/articles/s41746-026-02476-x3 aIn April 2025, the U.S. Food and Drug Administration announced immediate steps toward replacing animal testing for drug evaluation with New Approach Methodologies (NAMs)—modern laboratory techniques mimicking human tissues. However, significant gaps exist between current regulatory frameworks and these technologies’ promise. We argue that specific comprehensive regulatory reforms will improve transition to human-relevant drug-evaluation methodologies, laying groundwork for digital twins, in silico trials, and transformative advances in precision medicine. a2398-6352
