FDA releases biannual progress report on judicious use

FDA updates compliance with strategy for judicious use of antimicrobials in food-producing animals.

The U.S. Food & Drug Administration announced Feb. 26 its second progress report on its strategy to promote the judicious use of antimicrobials in food-producing animals.

In December 2013, the agency took a significant step forward in addressing antimicrobial resistance by publishing Guidance #213 (GFI #213), which calls on animal drug sponsors of approved medically important antimicrobials administered through medicated feed or water to remove from their product labels indications for use related to growth promotion, and bring the remaining therapeutic uses of these products under the oversight of a veterinarian by December 2016.

In March 2014, 283 applications were identified as being affected by GFI #213. Since that time, 11 new generic and combination approvals were added to the list of affected applications; by law, the agency has no basis for refusing to approve these applications as long as they meet regulatory standards for approval.

Some affected drug sponsors have already started implementing the recommended changes to their affected antimicrobial products: three applications have been converted from over-the-counter to prescription dispensing status; production indications have been withdrawn from one application, and 32 affected applications have been completely withdrawn, FDA reported.

FDA said sponsors of all of the affected applications, including the additions, remain committed to participating in the strategy. One drug sponsor who was not previously affected by GFI #213, Pharmgate LLC, acquired all of the affected applications of Pennfield Oil Co. and ADM Alliance Nutrition Inc. Pharmgate has notified the agency in writing of its intent to engage in the judicious use strategy as outlined in GFI #213.

FDA noted that it continues to work closely with affected drug sponsors to help ensure that the changes they agreed to make as described in GFI #213 are completed in an orderly manner by the end of December 2016. FDA also said it intends to use a variety of metrics to assess the effect of these changes over time, including existing data on drug sales and resistance as well as additional on-farm data.

The agency is working closely with the U.S. Department of Agriculture and the Centers for Disease Control to hold a joint public meeting in the spring of 2015 to discuss ways to collect and use on-farm use data. Details of the public meeting will be released closer to the meeting date.
