SUPPLEMENTARY INFORMATION: 

I. Background

    In the Federal Register of March 18, 2015 (80 FR 14146), FDA 
announced a public meeting to discuss the use of in vitro methods as a 
mechanism for assessing the in vivo product bioequivalence (BE) of 
nonsystemically absorbed drug products intended for use in veterinary 
species. In the same notice, FDA said that it is seeking additional 
public comment to the docket. Interested persons were originally given 
until May 18, 2015, to comment on this issue.

II. Request for Comments

    Following publication of the March 18, 2015, notification of public 
meeting and request for comments, FDA received a request to allow 
interested persons additional time to comment. The requester asserted 
that the time period of 60 days was insufficient to respond fully to 
FDA's specific requests for comments and to allow potential respondents 
to thoroughly evaluate and address pertinent issues.

this document to http://www.regulations.gov or written comments to the
