The FDA's September 2018 draft guidance for considerations of benefit-risk determinations for several device types, including PMAs, said that the agency "intends" to hold an advisory committee hearing if the FDA has any questions about the post-market data generated by the accompanying post-approval study. The final guidance pulls back on that language, but only slightly, stating that the agency "generally expects" to hold an advisory hearing in this circumstance, a difference in language that may or may not translate to a difference in function.
