FDA issues draft update on antimicrobial resistance

The guidance is a tool for assessing the risk of antimicrobial resistance in people, which could result from the use of a medically important antimicrobial drug in food-producing animals.

US Food and Drug Administration proposes revisions to guidance on evaluating safety of antimicrobial animal drugs based on their importance in human medicine

The U.S. Food and Drug Administration (FDA) issued a draft update to guidance for industry (GFI) #152, “Evaluating the Safety of Antimicrobial New Animal Drugs with Regard to Their Microbiological Effects on Bacteria of Human Health Concern.” The guidance is a tool for assessing the risk of antimicrobial resistance (AMR) in people, which could result from the use of a medically important antimicrobial drug in food-producing animals. The scope and purpose of updated GFI #152 remains the same as the initial version of the guidance issued in 2003.

Updates to the guidance include revisions to the risk assessment framework, updated ranking criteria for determining the degree of medical importance of antimicrobial drug classes, and a revised ranking of antimicrobial drug classes as critically important, highly important, or important based on the newly updated ranking criteria (Appendix A).

Other proposed changes include new text to address antimicrobial drugs that are not medically important (NMI), updates to the “Exposure” tables in collaboration with the United States Department of Agriculture’s Food Safety Inspection Service (FSIS) and Economic Research Service (ERS), and revised definitions in the “Glossary” section.

When proposing revisions to GFI #152, FDA took into account feedback from its 2020 concept paper and public meeting on a potential approach for ranking antimicrobial drugs according to their importance in human medicine.

Once FDA finalizes this revised draft GFI, the agency expects to reassess the rankings in Appendix A periodically to align with current science and clinical practices in human medicine.
