House passes bill directing FDA to update animal testing rules

The U.S. House passed the FDA Modernization Act 3.0, directing the FDA to update regulations to permit alternatives to animal testing in drug development, aligning federal rules with a 2022 law that already allowed non-animal methods. The bill awaits Senate approval and would accelerate the shift toward new approach methodologies (NAMs) such as organoids and organs-on-chips, with the FDA aiming to make animal studies the exception rather than the norm within three to five years.
