# SUPPLEMENTARY INFORMATION:

                    In the                     **Federal Register**                     of January 11, 2021, FDA published a notice of availability of a document entitled “Potential Approach for Defining Durations of Use for Medically Important Antimicrobial Drugs Intended for Use In or On Feed: A Concept Paper” with a 90-day comment period.                

Interested persons were originally given until April 12, 2021, to comment on the concept paper. The Agency has received requests to allow interested persons additional time to comment. The requests conveyed concern that the current 90-day comment period does not allow sufficient time to develop a comprehensive response. We have concluded that it is reasonable to extend the comment period for 60 days. The Agency believes that this extension allows adequate time for interested persons to submit comments.

Dated: February 16, 2021.

Lauren K. Roth,

Acting Principal Associate Commissioner for Policy.
