- HHS announced new initiatives to reduce animal testing in drug development, the second such announcement this year from the department.
- The FDA issued a final rule stating that research methods other than animal testing can be used when 'appropriate' for determining the safety of drugs and biologics.
- The rule replaces regulatory terms like 'animal tests' and 'animal studies' with 'nonclinical tests' and 'nonclinical studies' in FDA language.
- HHS Secretary Robert F. Kennedy Jr. framed the shift as moving 'toward a new era of biomedical research that puts human biology at the center of science' and 'modernizing outdated regulations.'
- Kennedy said HHS is 'investing in human-based technologies, and breaking down barriers that have kept researchers dependent on animal models when better tools are available.'
Why it matters: Drug developers gain formal regulatory permission to use non-animal methods to demonstrate drug and biologic safety, replacing decades-old animal-testing language in FDA regulations. Kennedy's framing positions the move as active regulatory modernization rather than aspirational policy, giving researchers a clearer mandate to adopt human-based technologies over animal models.
