FDA to replace animal testing terms with broader nonclinical language in regulations

The U.S. Food and Drug Administration announced it will revise its regulations to replace references to animal testing with broader terms such as "nonclinical tests" and "nonclinical studies".

The change is intended to make the regulatory language more flexible and to support the growing use of alternative, non-animal methods in drug development.

By updating the terminology, the agency hopes to streamline the review process for products that rely on modern testing approaches while still ensuring safety and efficacy standards.
