On Dec. 14, 2017, the FDA released a Draft guidance dated Dec. 15, 2017 “The Least Burdensome Provisions: Concept and Principles.” This guidance discusses FDA’s intent and approach to applying Least Burdensome Principles to the total product lifecycle for medical devices based on requirements in FDAMA (Public Law 105-115), the FDA Safety and Innovation Act (Public Law 112-144) (FDASIA) ,and the 21st Century Cures Act (Public Law 114-255) (Cures Act). This guidance stresses interactive approaches, tailored approaches, consideration of time and resources impact of its requests, use of post market data to reduce premarket data, timely patient access, leveraging internation data, alternative source of data versus clinical trial data, leveraging existing data rather then running new trials, use of read world data and non-clinical data and bench testing, use of computer modeling and simulation, non-comparative clinical outcome studies, risk benefit analysis, bundling multiple devices in a submission, exempting some Class I and II devices from 510(k) requirements, and in general requesting only the minimum information needed for making a regulatory decision.
