The use of real-world evidence (RWE)—derived from sources such as electronic health records (EHR) and claims data—has the potential to provide a more complete picture of patient experiences, reduce costs, and offer unique insights into important scientific questions. At the same time, there are relatively few examples to inform efforts to integrate RWE into clinical trials, as well as a lack of consensus among researchers about valid approaches for leveraging these data sources.

To address this issue, CTTI convened an expert meeting in June 2018 to discuss best practices and needed resources for advancing the use of RWE in randomized clinical trials. The meeting (see one-page summary) included investigators, patients, regulators, technology experts, sponsor representatives, and other groups.

While participants agreed that the use of RWE could be a major step forward in clinical trials, they stressed the importance of recognizing and planning for its limitations, including inconsistent data reliability and quality. They also agreed that direct interaction with participants and the integration of various real-world data sources is critical for improving the depth and breadth of available data.

As the next step in its Real-World Evidence work, CTTI will develop recommendations and resources for incorporating RWE into randomized trials for regulatory submission.
