the body of your comments, that information will be posted on https://www.regulations.gov.
     If you want to submit a comment with confidential

SUPPLEMENTARY INFORMATION: In the Federal Register of July 14, 2023 (88 
FR 45222), we published a notice of availability for a draft guidance 
entitled ``Manufacturing Changes and Comparability for Human Cellular 
and Gene Therapy Products; Draft Guidance for Industry.'' This action 
opened a docket with a 60-day comment period.
    We have received requests for a 30-day extension of the comment 
period for the draft guidance. We have considered the requests and are 
extending the comment period for the draft guidance for 60 days, until 
November 13, 2023. (A 60-day extension would fall on November 11, 2023, 
which is a Saturday, so we have extended the comment period until the 
next business day, which is November 13, 2023.) We believe that a 60-
day extension allows adequate time for interested persons to submit 
comments.

    Dated: August 21, 2023.
Lauren K. Roth,
Associate Commissioner for Policy.
