FDA issued its list of planned Medical Device Guidance development for 2018. This list has 2 parts: priority development referred to as the A-List and other development referred to as B-list.. Note that FDA does not commit to accomplishing all items on either list; it is just stating its current intention. The A-List includes a draft guidance for Validation of Automated Process Equipment Software. FDA also lists which pre-existing guidances they hope to retrospectively review in 2018.
