FDA finalizes approval process guidance
The FDA published final guidance GFI #187B, titled "Heritable Intentional Genomic Alterations in Animals: The Approval Process," and announced it in the Federal Register on January 7, 2025 (Docket No. FDA-2019-D-2648). If you develop heritable genomic alterations (IGAs) in animals, this guidance explains how the FDA approval process applies to those products.
Guidance clarifies technical and data expectations
The final guidance adds explanations and clarifications on multiple technical topics including: how FDA's animal safety review includes animal health and well-being; how compositional analysis relates to food safety evaluation; what constitutes a "significant change" for durability; what may be included in a single IGA-related application; acceptable methods for molecular characterization (including methods other than whole genome sequencing); what data constitute a "full characterization" of the alteration site and potential unintended alterations; and more detailed information on review timelines.
