This guidance is intended to clarify how the Food and Drug Administration (FDA or Agency) applies the factors set forth in section 505-1 of the Federal Food, Drug, and Cosmetic Act (FD&C Act) (21 U.S.C. 355-1) in determining whether a risk evaluation and mitigation strategy (REMS) is necessary to ensure that the benefits of a drug outweigh its risks. This guidance is one of several being developed to fulfill performance goals that FDA agreed to satisfy in the context of the fifth reauthorization of the prescription drug user fee program (the Prescription Drug User Fee Act (PDUFA) V). By providing greater clarity about FDA’s application of these statutory factors, FDA hopes to increase understanding about how and when FDA determines that a REMS is required.
