Integrating Human Intestinal Organoids into FDA'S New Approach Methodologies for Drug Discovery

open access: yesAdvanced Science, EarlyView.
Illustration summarizes how human intestinal organoids (HIOs) are becoming transformative in preclinical research. Preclinical drug discovery pipelines often rely on animal models for ADMET studies, even though interspecies ADME gaps, poor external validity, and high attrition rates are common.
