The U.S. Food and Drug Administration has withdrawn 47 draft guidance documents published before December 31, 2013, which were never finalized or acted on. The announcement was posted in the Federal Register, stating that this move was made to improve the efficiency and transparency of the guidance development process, since many of these guidances were never completed to due to higher priorities, funding issues, emerging technologies, and outdated information.

These documents covered medical devices, pharmaceuticals, diagnostic devices, and more.

Companies wishing to comment on any of the agency's specific withdrawals should submit their comments by June 5, 2015. Electronic comments can be delivered to the agency via the federal e-rulemaking portal at http://www.regulations.gov .
