Summary
FDA Modernization Act 3.0This bill requires the Food and Drug Administration (FDA) to publish an interim final rule implementing a provision of the Consolidated Appropriations Act of 2023 that authorized the use of certain alternatives to animal testing to support investigational use of a new drug. The rule must replace references to animal tests, data, studies, models, and research with references to nonclinical tests, data, studies, models, and research throughout the FDA’s regulations governing investigational new drug applications, and may make other changes to the regulations as appropriate. The rule must be published within one year of the bill’s enactment, and must take immediate effect as an interim final rule.

What changed in the latest version
30 added · 34 removedPlain-language change summary
The amendment updates a bill to clarify that the Secretary of Health and Human Services must publish an interim final rule to replace references to "animal" tests with "nonclinical" tests in specific sections of the Code of Federal Regulations. It also specifies that a definition for "nonclinical test" will be added to certain sections of the Federal Food, Drug, and Cosmetic Act. This change matters as it formally establishes the terminology and framework for testing without using animal methods in the regulatory context.
