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 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. Following publication of 
that notice, FDA received a request to allow interested persons 
additional time to comment. In response to that request, FDA published 
a Federal Register notice on June 10, 2015, reopening the comment 
period for 60 days, until August 10, 2015.

II. Request for Comments

    Following publication of the June 10, 2015, notice reopening the 
comment period for 60 days, FDA received a request to allow interested 
persons an additional 30 days to comment. FDA has considered the 
request and is reopening the comment period for 30 days, until November 
2, 2015.

    Dated: September 28, 2015.

Associate Commissioner for Policy.
