§355g Utilizing real world evidence

Summary

The Secretary must set up a program to test how “real world evidence” can be used to support a new approved use for a drug and to meet post‑approval study needs. Real world evidence means information about how a drug is used or its benefits or risks that comes from sources other than traditional clinical trials. The Secretary must write a draft plan within 2 years after December 13, 2016, saying where such data can come from (for example, safety monitoring, observational studies, registries, insurance claims, and patient‑outcome research), what data are missing, how to collect and analyze the data, and what priority problems or pilot projects to try. The Secretary must consult industry, academia, doctors, patient groups, consumer groups, research foundations, and others, and may do this through partnerships, contracts, or public workshops. The program must be put into action within 3 years after December 13, 2016. The Secretary must use the program and any pilot work to make guidance for industry about when and how to rely on real world evidence and what standards to use. A draft guidance must be published within 5 years after December 13, 2016, and a revised draft or final guidance must follow within 18 months after the public comment period ends. The Secretary may use real world evidence for other purposes if there is a sufficient basis, but this law does not change existing evidence standards for drugs or biologics or the Secretary’s authority to require postapproval studies or clinical trials.
