Intentional Genomic Alterations (IGAs) in Animals: Risk-Reviewed IGAs

FDA’s Center for Veterinary Medicine’s (CVM) oversight of Intentional Genomic Alterations (IGAs) in animals includes a risk-based evaluation with a particular focus on safety. What this means in practice is that, while IGA developers are generally required to have an approved application for IGAs in animals prior to marketing, as described below, for those alterations where FDA has concluded that we understand the product’s risks for the specified intended use and we have no safety concerns, the Agency may not expect developers to seek approval of these IGAs.

For IGAs in animals that are in non-food producing species and that are either under other government oversight or are raised in contained and controlled laboratory conditions for research (e.g. mice), CVM has said that it will exercise enforcement discretion without a prior review of data. For other IGAs in animals, CVM has said that it may exercise enforcement discretion on a case-by-case basis if, after a risk-based review, it determines that the product or category of products has risks that we understand, any identified risks are appropriately mitigated, and we have no further questions for which we would need to see additional data to address.

Below is a list of those IGAs in animals that, following a risk-based review, FDA has determined we do not expect submission of an application for approval. This is not a determination of “safety” under the Federal Food, Drug, and Cosmetic Act but is instead a determination that we understand the product’s risks for the specified intended use and have concluded we have no safety concerns. If FDA becomes aware of new information about risk, it may revisit these decisions.

To increase transparency, FDA, with permission from the developer, intends to publish a summary of the types of data and information it evaluated and its conclusions for risk-reviewed products that are for food use or first of their kind on the market.
