The Food and Drug Administration (FDA or Agency) is announcing the availability of a final guidance for industry entitled “Real-World Data: Assessing Electronic Health Records and Medical Claims Data To Support Regulatory Decision-Making for Drug and Biological Products.” FDA is issuing this guidance as part of its Real-World Evidence (RWE) program and to satisfy, in part, the mandate under the Federal Food, Drug, and Cosmetic Act (FD&C Act) to issue guidance about the use of RWE in regulatory decision making. This guidance is intended to provide sponsors and other interested parties with considerations when proposing to use electronic health records (EHRs) or medical claims data in clinical studies to support a regulatory decision for effectiveness or safety. This guidance finalizes the draft guidance of the same title issued on September 30, 2021.
