New approach methodologies for drug discovery

# New approach methodologies for drug discovery *Published: 2026 Apr 2* Traditional animal-based drug discovery has high failure rates, prompting the search for and adoption of human-centered new approach methodologies (NAMs). Rapid advances in stem cell-, organoid-, and in silico-based NAMs, supported by evolving frameworks from the National Institutes of Health (NIH) and the Food and Drug Administration (FDA), now span the entire drug-discovery continuum, from disease modeling and drug design to efficacy testing. Our review highlights recent progress across these domains, including the identification of therapeutic candidates, the development of cutting-edge models and technologies, and the potential of NAMs themselves as treatments in preclinical and clinical contexts, while examining the key biological, technical, and regulatory bottlenecks that need to be addressed to enable robust translational adoption. We conclude by discussing the translational and societal considerations essential to the responsible adoption of NAMs and outlining future human-centric pipelines poised to redefine the landscape of drug discovery.
