SUPPLEMENTARY INFORMATION:

I. Background

    After a series of workshops with interested partners and FDA-
sponsored research in the 1990s, FDA's Center for Drug Evaluation and 
Research developed a risk-based approach for implementing chemistry, 
manufacturing, and controls (CMC) changes that could affect identity, 
strength, quality, purity, or potency of a drug product as these 
factors may relate to the safety or effectiveness of the drug product. 
This risk-based approach was first explained in the SUPAC guidances, 
which describe the recommended testing and documentation for component 
and composition changes, manufacturing process and equipment changes, 
manufacturing scale changes, and manufacturing site changes. The intent 
of this risk-based approach was to reduce the regulatory burden of 
obtaining FDA approval for certain CMC changes to approved applications 
that were not likely to affect the identity, strength, quality, purity, 
or potency of a drug product and, therefore, the safety or 
effectiveness of the drug product.
    In November 1997, the risk-based approach for implementing CMC 
changes that was introduced in the SUPAC guidances was codified in 
section 116 of the Food and Drug Administration Modernization Act 
(FDAMA) (Pub. L. 105-115). Section 116 of FDAMA amended the Federal 
Food, Drug, and Cosmetic Act (FD&C Act) by adding section 506A (21 
U.S.C. 356a), which describes requirements and procedures for making 
and reporting any CMC changes to approved applications, including new 
and abbreviated new drug applications. On April 8, 2004, FDA issued the 
final rule to implement section 506A of the FD&C Act (69 FR 18728). The 
final rule requires applicants to assess the effects of CMC changes on 
the identity, strength, quality, purity, and potency of a drug product 
as they may relate to the safety and effectiveness of the product. 
Further, the final rule sets forth submission requirements, based on 
the characterization of the CMC change (e.g., major, moderate, or 
minor), that must be met before the distribution of the product made 
using the change (see 21 CFR 314.70). In the preamble to the final 
rule, FDA acknowledged that when section 116 of FDAMA was written it 
was anticipated that ``the science of manufacturing would evolve over 
time,'' and that ``FDA may, by regulation or guidance, change the 
designation of a particular category of change from major to nonmajor 
or vice versa'' (69 FR 18728 at 18729). The final rule was effective on 
June 22, 2004.
    Except for SUPAC-MEA, which was updated in 2014, the SUPAC 
guidances were finalized between 1995 and 1997. Since then, the use and 
evolution of risk assessment tools in pharmaceutical development has 
enhanced the ability to identify, categorize, and control risks 
associated with a CMC change that impact product quality. We have 
determined that the SUPAC guidances may benefit from additional public 
comment on the topics outlined in this notice to ensure that these 
guidances align with current expectations, risk assessment strategies, 
and contemporary scientific and technical considerations.

II. Issues for Consideration and Requested Information and Comments

    Despite the time that has elapsed since the SUPAC guidances were 
implemented, the core principle of a risk-based approach for 
implementing

[[Page 10399]]

CMC changes as described in the guidances remains relevant. The SUPAC 
guidances assist in reducing the number of CMC changes that require 
approval of a supplemental application, which can minimize delays in 
distribution of the product, give companies greater control over their 
production resources, and result in significant net savings to 
industry. In addition, the SUPAC guidances allow FDA to focus resources 
on those changes that pose the greatest risk to product quality thereby 
improving efficiency and promoting timely continual improvement in 
accordance with current good manufacturing practice. We acknowledge, 
however, that the effectiveness of the SUPAC guidances may be impacted 
by subsequent guidances (e.g., ICH Q9(R1) and ICH Q12)), where 
particular recommendations in those guidances either supersede or 
potentially conflict with certain recommendations in the SUPAC 
guidances. For example, the principles described in ICH Q12 (e.g., how 
enhanced development can inform the nature and extent of established 
conditions, further elaboration on change management as an aspect of 
the pharmaceutical quality system) are intended to enhance industry's 
ability to manage many CMC changes with greater efficiency and with 
less regulatory oversight prior to implementation of the change. 
Accordingly, FDA is considering updating the SUPAC guidances to improve 
their utility and effectiveness in light of evolving science, to ensure 
they continue to reflect the Agency's current thinking on risk-based 
approaches to CMC changes, and to enable manufacturers to more 
effectively evaluate changes within their quality systems prior to 
submitting a CMC change for evaluation.
    Interested persons are invited to provide detailed comments and 
information related to the contents of this notice. To facilitate 
input, we have developed the following questions about the SUPAC 
guidances:
    1. How are the recommendations provided in the SUPAC guidances 
still helpful and meaningful to regulated industry?
    a. Are there sections of the SUPAC guidances that are particularly 
beneficial and are important to retain, either partially or in their 
entirety, because they reflect current risk-based approaches and are 
currently being referenced by applicants to support CMC changes?
    b. Are the risk-based principles described in the SUPAC guidances 
being used to help inform applicants in other ways in addition to 
supporting CMC changes?
    2. What challenges do you have when interpreting or applying the 
recommendations in the SUPAC guidances?
    a. Are there sections of the SUPAC guidances that should be removed 
because they are no longer relevant or meaningful?
    b. When referencing the SUPAC guidances for recommendations on a 
CMC change, are you able to effectively evaluate changes within your 
quality system and readily identify both the type and the corresponding 
level of change (i.e., major, moderate, or minor) based on the 
information provided in the SUPAC guidances? If not, please specify 
what challenges you have when making this determination.
    c. Are there areas of overlap or inconsistencies among the various 
SUPAC guidances or in other FDA guidances on CMC changes that may cause 
confusion when trying to apply the recommendations? Please specify the 
areas of overlap or inconsistencies.
    3. How can FDA provide clarity on the recommendations provided in 
the SUPAC guidances? For example:
    a. Should FDA consider reorganizing the content in the SUPAC 
guidances, for example, by either combining the multiple SUPAC 
guidances into a single guidance, or separating topics in the 
individual guidances, so that recommendations are easier to interpret 
and apply?
    b. Are there recommendations from other FDA guidances, for example, 
the studies described in the draft guidance for industry titled 
``Physicochemical and Structural (Q3) Characterization of Topical Drug 
Products Submitted in ANDAs'' (87 FR 64230),\1\ that if included in the 
SUPAC guidances, might help to reduce regulatory burden?
---------------------------------------------------------------------------

    \1\ When final, this guidance will represent the FDA's current 
thinking on this topic. For the most recent version of a guidance, 
check the FDA guidance web page at https://www.fda.gov/regulatory-information/search-fda-guidance-documents.
---------------------------------------------------------------------------

    c. How might the recommendations in the SUPAC guidances be better 
aligned with current risk assessment and postapproval lifecycle 
management principles and tools (e.g., postapproval change management 
protocols, established conditions)?
    4. Are there new topics that should be added to the SUPAC 
guidances?
    These questions are not meant to be exhaustive, and we are also 
interested in any other pertinent information interested persons would 
like to share on this topic. This feedback will help inform the 
Agency's general policy development direction. FDA encourages 
commenters to provide the specific rationale and basis for their 
comments, including any available supporting data and information.
