This post was written by Paul Sheives. A recent GAO report points to improvement in FDA’s postmarket drug safety oversight, but the agency expresses concern over continued gaps in particular areas. The GAO recommended that FDA develop a plan and timeline for transferring additional regulatory authorities from the Office of New Drugs to the Office of Surveillance and Epidemiology. FDA comments regarding the report were generally supportive, but the agency is hesitant to commit to any timelines.
