The Biotechnology Innovation Organization (BIO) says that FDA could minimize ambiguity when it finalizes a draft guidance, “Chemistry, Manufacturing, and Controls Postapproval Manufacturing Changes for Specified Biological Products to Be Documented in Annual Reports,” by giving examples of situations where annual reportable listed changes in the guidance may be better categorized by applicants as a supplement, based on specific circumstances.
