FDA and Real-World Evidence in 2019

Around the end of 2018, FDA published the “Framework for FDA’s Real-World Evidence Program” (the “Framework”).[1] The Framework is to provide a basis for the agency in evaluating the potential use of real-world evidence (RWE) in regulatory decisions involving drug and biological products.[2] The Framework laid out a “three-part approach” identifying data quality, study design, and regulatory requirements as focal points of the evaluation. In addition, the Framework pointed to the importance of data standards in enabling efficient processing of real-world data (RWD), from which RWE is derived. In 2019, to refine its understanding of these four areas (data quality, study design, regulatory requirements, and data standards) in the context of RWE, FDA coordinated a multifaceted effort including demonstration projects, development of guidance documents, the Sentinel System, and active engagement with sponsors and other stakeholders.

In 2019, FDA expanded some of its existing demonstration projects, while funding new ones. In April, Aetion announced that FDA and Brigham and Women’s Hospital/Harvard Medical School will expand the scope of their demonstration project to include predicting seven ongoing randomized control trials (RCTs) with RWE, in addition to the original scope of replicating 30 completed RCTs.[3] In August, a San Francisco-based company Syapse announced that it will work with FDA to assess the potential of RWE especially in the context of precision medicine.[4] While some have criticized these studies,[5] demonstration projects seem to remain a core part of FDA’s Real-World Evidence Program (the “Program”).

In May, FDA published a draft guidance entitled “Submitting Documents Using Real-World Data and Real-World Evidence to FDA for Drugs and Biologics.”[6] The industry reaction was mixed, some cautioning while others encouraging the use of RWE.[7] Notably, some of the pharmaceutical companies asked the agency to consider data from Expanded Access programs as a source of RWD, in response to the draft.[8] While expanding the scope of RWD in such a way may incentivize companies to more actively engage in FDA’s Expanded Access and Right to Try programs,[9] it remains to be seen how the agency’s subsequent treatment of RWE interacts with the level of industry participation in those programs.

The Sentinel contract in September marked another step forward in FDA’s endeavor to incorporate RWE into its regulatory practice. According to Jacqueline Corrigan-Curay, FDA’s Director of CDER’s Office of Medical Policy, the contract “will really enable FDA to continue to grow its own RWE capabilities.”[10] The contract will fund up to $220 million for five years starting in 2019, for the next phase of the Sentinel System,[11] which is to become a platform that generates RWE for FDA.[12]

Lastly, FDA supported and sponsored workshops to exchange insights with stakeholders. In July, through a public workshop titled “Leveraging Randomized Clinical Trials to Generate Real-World Evidence for Regulatory Purposes,” FDA explored the potential use of RWD not only in single-arm trials but also in randomized clinical trials.[13] Also in July, FDA sponsored a workshop titled “FDA-AACR Real-world Evidence Workshop,” discussing the use of large genomic databases and digital data as RWD, among other things.[14] In October, at a conference entitled “Developing Real-World Data and Evidence to Support Regulatory Decision-Making,” FDA and various stakeholders exchanged thoughts on the key evaluation areas laid out in the Framework.[15] Through these workshops, FDA has shown that it is open to a wide range of creative solutions, while understanding that it may have to take one step at a time.[16]

In parallel with its pursuit under the Program, FDA in September announced a Technology Modernization Action Plan.[17] In justifying the timeliness of this plan, FDA explained that a modernized technical infrastructure will be necessary for the agency to accept and process RWD and to derive RWE for its regulatory decision-making, specifically referring to the Framework and the Program. This explanation seems to reach beyond the scope of the Program (and the congressional mandate by the 21st Century Cures Act), which simply sets out to evaluate the potential use of RWE.[18]

Finally, it is worth noting how RWE continued to play a role in supporting drug approvals in 2019, especially in the context of cancer and rare diseases. For instance, FDA’s Oncology Drugs Advisory Committee last month unanimously recommended accelerated approval of a drug (tazemetostat) for a rare form of cancer,[19] where the approval was supported in part by a Natural History Study.[20] Further, FDA in April approved a new indication of a drug (palbociclib) primarily based on RWD such as electronic health records and post-marketing reports.[21] The approval is one of the rare cases where FDA accepted RWE to support an effectiveness decision (rather than a safety evaluation), and will serve as a precedent for future drug approvals. Given FDA’s willingness apparent in the Framework to further explore the use of RWE in effectiveness decisions, it seems likely that RWE will play a bigger role in drug approval processes in 2020.

In short, FDA in 2019 tapped into multiple channels to gather input from stakeholders and also to broaden its own experience with RWD and RWE. Although the exact outcome of these endeavors remains to be seen in 2020, the agency appears to be slowly but surely getting ready to incorporate more RWE into its regulatory decisions.
