FDA Announces ADUFA/AGDUFA Reauthorization Draft Recommendations and Extension of Comment Period

October 24, 2017

Today, the U.S. Food and Drug Administration announced its draft recommendations developed for submission to Congress for the reauthorization of the Animal Drug User Fee Act (ADUFA) and Animal Generic Drug User Fee Act (AGDUFA). The agency is also extending the currently open comment periods until November 24, 2017 to allow interested persons to submit comments on these draft recommendations.

ADUFA and AGDUFA give the FDA the authority to collect user fees that provide supplemental funding to support the new animal drug and generic new animal drug review processes, respectively. These resources support the FDA’s responsibility to review these drugs for safety and effectiveness and to enhance the timeliness and predictability of application reviews.

The current authorizations for ADUFA and AGDUFA expire on September 30, 2018. Without new legislation reauthorizing these programs, FDA will no longer have the authority to collect user fees to help support the new animal drug and generic new animal drug review processes.

The proposed recommendations for ADUFA and AGDUFA are divided into four categories: Enhancing the Process for Premarket Review; Inflation Adjuster and Workload Adjuster; Offset Provision and Excess Collections; and the impact of the recommended changes on user fee revenue. Details on these recommendations and information on the extension of the comment period are available at:

As previously announced , the FDA is also holding two public meetings on November 2, 2017, one on ADUFA reauthorization and one on AGDUFA reauthorization, to offer opportunity for discussion on the proposed recommendations.
