The purpose of this legislation, known as the Replace Animal Tests Act of 2025, is to promote the use of non-animal testing methods for regulatory purposes whenever scientifically valid alternatives are available. The goal is to reduce reliance on animal testing in favor of methods that do not involve live animals, thereby addressing ethical concerns and advancing scientific practices. Key provisions of the Act include a prohibition on submitting data derived from animal testing to regulatory agencies if a non-animal testing method is available.
