SUPPLEMENTARY INFORMATION: 

I. Background

    FDA is announcing the availability of a draft guidance for industry 
entitled ``Postapproval Changes to Drug Substances.'' As part of the 
reauthorization of the Generic Drug User Fee Amendments (GDUFA II), FDA 
committed to issuing a guidance on postapproval changes to Type II 
Active Pharmaceutical Ingredients Drug Master Files (DMFs) and 
submission mechanisms for abbreviated new drug application holders who 
reference such DMFs (see GDUFA Reauthorization Performance Goals and 
Program Enhancements Fiscal Years 2018-2022, known as the GDUFA II 
Commitment Letter, at https://www.fda.gov/downloads/ForIndustry/UserFees/GenericDrugUserFees/UCM525234.pdf). This draft guidance is 
intended to fulfill that commitment by describing the documentation for 
master file holders or drug substance manufacturers, as appropriate. 
The documentation to be submitted by the approved application holder is 
also outlined, and references to the appropriate pathways for such 
submissions are provided.
    A letter of authorization must be provided for an applicant to 
reference a DMF for the proposed drug substance Sec.  314.420(b) (21 
CFR 314.420(b)). Any addition, change, or deletion of information in 
the master file must be submitted to the master file in the form of an 
amendment (see Sec.  314.420(c)). Further, the master file holder must 
notify each person authorized to reference the DMF of the nature of the 
changes, and should provide as much detail as is consistent with the 
confidentiality agreement between the master file holder and the 
authorized person, so that the authorized person can determine how to 
report the changes in the approved application (see Sec.  314.420(c)). 
In turn, application holders must notify FDA of each change in each 
condition established in an approved application, excluding the 
variations already provided for in the application (Sec. Sec.  314.70, 
314.97, 514.8).
    When drug substance information is contained in an application, 
rather than in a referenced DMF, such changes must be submitted to FDA 
in the form of a supplement to the approved application or in an annual 
report (Sec. Sec.  314.70, 314.97, 514.8).
    This draft guidance addresses how the risk of one or more change(s) 
to the drug substance should be assessed and provides recommendations 
regarding the documentation needed to support such changes for the drug 
substance, and where applicable, for the drug product made with 
modified drug substance. The draft guidance covers the following 
changes: (1) facility, scale, and equipment changes associated with all 
steps of drug substance manufacturing; (2) specification changes to 
starting materials, raw materials, intermediates, and the unfinished 
and final drug substance; (3) synthetic manufacturing process changes; 
(4) changes in the source of drug substance; and (5) change to 
container closure system of the drug substance.
    This draft guidance does not address postapproval changes to 
peptides, oligonucleotides, radiopharmaceuticals; or drug substances 
isolated from natural sources or produced by procedures involving 
biotechnology; or nonsynthetic steps (such as fermentation) for 
semisynthetic drug substances. This draft guidance also does not 
address complex active ingredients as defined in the GDUFA II 
Commitment Letter.
    This draft guidance is being issued consistent with FDA's good 
guidance practices regulation (21 CFR 10.115). The draft guidance, when 
finalized, will represent the current thinking of FDA on Postapproval 
Changes to Drug Substances. It does not establish any rights for any 
person and is not binding on FDA or the public. You can use an 
alternative approach if it satisfies the requirements of the applicable 
statutes and regulations. This guidance is not subject to Executive 
Order 12866.

II. Paperwork Reduction Act of 1995

    This draft guidance refers to previously approved collections of 
information found in FDA regulations. These collections of information 
are subject to review by the Office of Management and Budget (OMB) 
under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). The 
collections of information in Sec.  314.70 have been approved under OMB 
control number 0910-0001; the collections of information in 21 CFR part 
211 have been approved under OMB control number 0910-0139; and the 
collections of information in 21 CFR 514.8 have been approved under OMB 
control number 0910-0032. In accordance with the PRA, prior to 
publication of any final guidance document, FDA intends to solicit 
public comment and obtain OMB approval for any information collections 
recommended in this draft guidance that are new or that would represent 
material modifications to those previously approved collections of 
information found in FDA regulations or guidances.
