FDA recently released the framework for its Real World Evidence (RWE) program, educating stakeholders about the agency’s approach to RWE when making efficacy decisions. The document is notable more for its discussion of the limitations rather than the potential for RWE. Although FDA plans to issue a number of RWE guidance documents and conduct RWE stakeholder events, the path to routine use of RWE looks to be a long and winding one.
Crucial to understanding FDA’s RWE approach is understanding the distinction between Real World Data (RWD) (e.g., data on patient health status and/or delivery of routine healthcare from a variety of sources) and RWE (e.g., clinical evidence on the use and potential benefits/risks of medical products derived from RWD). FDA intends to limit RWE use to supplemental indications and label changes for approved drugs/biologics (e.g., adding/modifying indications, changing dose/dosing regimens and routes of administration, adding new patient populations, adding comparative effectiveness/safety information). Moreover, while the life sciences industry tends to see the opportunities from RWD (e.g., electronic health record, medical claims/patient billing, patient/disease registry, and mobile device data), FDA primarily sees this information as an RWE source. This is not to say, however, that RWD is without use, as FDA plans to allow its use to improve study efficiency.
