[Docket No. FDA-2019-N-1363]
RIN 0910-AH50
Biologics License Applications and Master Files
AGENCY: Food and Drug Administration, HHS.
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Food and Drug Administration (FDA, the Agency, or we) is
proposing to amend its regulations concerning the use of master files
for biological products. This action, if finalized, will allow certain
biological products approved under the Federal Food, Drug, and Cosmetic
Act (FD&C Act) to continue to incorporate by reference information
about drug substances, drug substance intermediates, or drug products
contained in master files after those products are deemed to be
licensed under the Public Health Service Act (PHS Act) on March 23,
2020. The proposed rule also codifies FDA's practice of permitting
applications for biological products submitted under the PHS Act to
incorporate by reference information other than drug substance, drug
substance intermediate, or drug product information contained in a
master file. In addition, the proposed rule codifies FDA's practice of
permitting investigational new drug applications to incorporate by
reference any information contained in a master file for products
subject to licensure under the PHS Act.

I. Executive Summary
A. Purpose of the Proposed Rule
FDA proposes to amend its regulations to implement certain aspects
of section 7002(e) of the Biologics Price Competition and Innovation
Act of 2009 (BPCI Act). The proposed rule is necessary to avoid
unnecessary disruptions with respect to biological products originally
approved under section 505 of the FD&C Act (21 U.S.C. 355) when their
applications are deemed to be licenses under the PHS Act and to prevent
potential drug shortages when those products are transitioned to being
regulated under section 351 of the PHS Act (42 U.S.C. 262). The
proposed rule will also update the regulation to reflect FDA's
longstanding practices regarding the use of master files referenced in
applications for biological products submitted under section 351 of the
PHS Act.
B. Summary of the Major Provisions of the Proposed Rule
FDA proposes to amend its regulations concerning the use of master
files for biological products. The proposed rule would allow certain
biological products, originally approved in a new drug application
(NDA) under the FD&C Act, to continue relying on a drug master file for
information on a drug substance, drug substance intermediate, or drug
product (DS/DSI/DP) after the NDA is deemed to be a license for a
biological product under the PHS Act on March 23, 2020. The proposed
rule also codifies FDA's existing practice that a biological product in
a biologics license application (BLA) under the PHS Act may rely on a
master file, except for information regarding a drug substance, drug
substance intermediate, or drug product. In addition, the rule codifies
FDA's practice that an investigational new drug application (IND) for a
biological product may incorporate by reference any information,
including drug substance, drug substance intermediate, and drug product
information, contained in a master file.
C. Legal Authority
FDA is proposing to amend its regulations, in part, to implement
section 7002(e) of the BPCI Act. FDA's authority for this rule also
derives from the biological product provisions of the PHS Act (42
U.S.C. 262 and 264), and the provisions of the FD&C Act (21 U.S.C. 321,
et seq.) applicable to drugs, including section 701 (21 U.S.C. 371);
the FD&C Act provisions are applicable to biological products under
section 351(j) of the PHS Act.
D. Costs and Benefits
FDA anticipates that affected entities would incur minimal costs to
read and understand the rule. By allowing transitioned products to
continue to incorporate by reference information contained in existing
master files, FDA avoids imposing a potential new regulatory burden.
FDA projects that over 10 years at a discount rate of 7 percent the
proposed rule would generate annualized net cost savings ranging from
$0.3 million to $4.6 million with a primary estimate of $2.5 million;
over 10 years at a discount rate of 3 percent the proposed rule would
generate annualized net cost savings ranging from $0.3 million to $4.8
[[Page 30970]]
million with a primary estimate of $2.6 million.

III. Background
A. Introduction
This proposed rule, when finalized, would amend FDA regulations
relating to the use of master files in applications for biological
products subject to regulation under the PHS Act. Section 7002(b)(1) of
the BPCI Act revised section 351(i) of the PHS Act, in part, to amend
the definition of a ``biological product'' to include a ``protein
(except any chemically synthesized polypeptide).'' \1\ A number of
products approved in NDAs under section 505 of the FD&C Act meet the
revised definition of biological product. Also, section 7002(e)(4) of
the BPCI Act provided that, on March 23, 2020, an application for a
biological product approved under section 505 of the FD&C Act ``shall
be deemed to be a license for the biological product under'' section
351 of the PHS Act. This rule implements FDA's interpretation of the
``deemed to be a license'' provision of the BPCI Act with respect to
the use of master files.\2\ In addition, this rule codifies current
Agency practices relating to the use of master files referenced in
applications for biological products.
---------------------------------------------------------------------------
\1\ On December 12, 2018, FDA issued a proposed rule regarding
its interpretation of the terms ``protein'' and ``chemically
synthesized polypeptide'' as used in section 351(i) of the PHS Act
(``Definition of the term `Biological Product' '', 83 FR 63817).
\2\ For more information about FDA's interpretation of the
``deemed to be a license'' provision of the BPCI Act, see guidance
for industry entitled ``Interpretation of the `Deemed to be a
License' Provision of the Biologics Price Competition and Innovation
Act of 2009'' (December 2018). We update guidances periodically. To

FDA Drugs guidance web page at https://www.fda.gov/Drugs/GuidanceComplianceRegulatoryInformation/Guidances/default.htm.
---------------------------------------------------------------------------
B. FDA's Current Regulatory Framework
1. What are master files?
Master files are submissions to the Agency that may be used to
provide detailed, confidential information to the Agency about
facilities, processes, or articles used in the manufacturing,
processing, packaging, or storing of one or more human drugs.
Information contained in a master file can be used to support a
submission to FDA by an applicant or sponsor. The holder of a master
file can authorize one or more applicants or sponsors to incorporate by
reference information contained in the master file to support a
submission to FDA without having to disclose the information in that
master file (which may contain trade secrets or other confidential
commercial information) to the applicants or sponsors.3 4
The submission of a master file is at the sole discretion of the master
file holder. Ordinarily, FDA neither independently reviews nor approves
submissions to a master file; instead, the Agency reviews such
information only in the context of an application that incorporates by
reference information contained in that master file.
---------------------------------------------------------------------------
\3\ See, e.g., 21 CFR 314.420 and 47 FR 46622 at 46642 (October
19, 1982).
\4\ The holder of a master file (including a drug master file)
who expects that information in the file will be incorporated by
reference both in a BLA and in an NDA or abbreviated new drug
application (ANDA) need only submit the master file to the Agency
once.
---------------------------------------------------------------------------
a. Drug master files. Some master files contain information that is
relevant to applications for drug products. For products regulated
under section 505 of the FD&C Act, FDA defines the term ``drug master
file'' (DMF) in its drug regulations (Sec. 314.420(a) (21 CFR
314.420(a))) and explicitly provides that ``[a]n investigational new
drug application or an application, abbreviated application, amendment,
or supplement may incorporate by reference all or part of the contents
of any drug master file in support of the submission'' if the holder of
the master file authorizes the incorporation (Sec. 314.420(b)).
Section 314.420 also describes several types of DMFs, each of which
typically contains certain kinds of information (Sec. 314.420(a)):
Drug substance, drug substance intermediate, and materials used in
their preparation, or drug product (referred to as Type II DMFs);
packaging materials (Type III); excipient, colorant, flavor, essence,
or materials used in their preparation (Type IV); and FDA-accepted
reference information (Type V). (See also FDA Guidance for Industry
entitled ``Drug Master Files: Guidelines,'' September 1989, available
at https://www.fda.gov/Drugs/GuidanceComplianceRegulatoryInformation/Guidances/ucm122886.htm (accessed March 2019).)
b. Other master files. FDA also permits reference to master files
that are not addressed by Sec. 314.420, some of which contain
information that is relevant to applications for biological
products.\5\ The Agency's approach to the terminology for types of
master files used for products regulated under the PHS Act has
generally tracked its approach to the types of DMFs (e.g., Type II,
Type III) used for products regulated under the FD&C Act.
---------------------------------------------------------------------------
\5\ See, e.g., 21 CFR 601.51(a).
---------------------------------------------------------------------------
2. Biologics License Applications and Master Files
a. FDA generally permits BLAs to incorporate by reference
information contained in master files. Just as FDA permits NDAs and
ANDAs under the FD&C Act to incorporate by reference certain
information contained in DMFs, the Agency also generally permits
applications under the PHS Act (BLAs) to incorporate by reference
certain information contained in master files, including DMFs.
For most categories of information and most application types
(including BLAs and INDs), the needs of master file holders, applicants
and sponsors, and FDA have been adequately met through this
incorporation-by-reference mechanism. This mechanism allows applicants
and sponsors to refer to information contained in master files without
having knowledge of the contents of those master files (Sec. 314.420;
47 FR 46622 at 46642). For products licensed under section 351 of the
PHS Act, FDA has permitted, and will generally continue to permit, the
use of information contained in most types of master files (such as
information about excipients, stabilizers, penetrants, or materials
used in the preparation of DS/DSI/DP) because the applicant generally
has the ability to independently identify and mitigate the risk posed
to product quality by such components. For example, applicants are
permitted to incorporate by reference in their BLA information on
container closures contained in a master file. This is the case because
an applicant can independently identify the risk to product quality
posed by a container closure (for example, by leachables in the
closure) by performing appropriate studies on stability and
adequateness for intended use and then taking steps to
[[Page 30971]]
mitigate any risks identified (for example, by implementing appropriate
testing and controls). Thus, in such cases, the feasibility of testing
to confirm the adequateness of intended container closures mitigates
the risks to quality arising from the applicant's lack of access to the
information contained in the master file.
Accordingly, proposed Sec. 601.2(i) would codify FDA's
longstanding practice of permitting biological products in BLAs to
incorporate by reference most categories of information contained in
master files (other than information about DS/DSI/DP, discussed below).
b. FDA currently does not permit biological products in BLAs to
incorporate by reference drug substance, drug substance intermediate,
or drug product information in master files. Although FDA's approach to
the use of master files in BLAs largely parallels its approach to the
use of DMFs in applications under the FD&C Act, there is a significant
difference: Unlike applications submitted under section 505 of the FC&C
Act, for biological products in BLAs, the Agency has, as a scientific
matter, expected applicants to submit information about DS/DSI/DP
directly to the BLA rather than incorporating it by reference to a
master file. (See, e.g., FDA Guidance for Industry entitled ``Quality
Considerations in Demonstrating Biosimilarity of a Therapeutic Protein
Product to a Reference Product'' April 2015, available at https://www.fda.gov/downloads/drugs/guidancecomplianceregulatoryinformation/guidances/ucm291134.pdf (accessed March 2019).)
The risk associated with the manufacture of complex biological
products is generally significantly higher than that associated with
the manufacture of chemical entities, which are often less complex.\6\
This is because most biological products tend to have certain features
(e.g., amino acid sequence, glycosylation, folding, cellular phenotype)
essential to their intended effect and can be very sensitive to changes
to their manufacturing process. In addition, biological products
derived from biological sources may be complex heterogeneous mixtures,
which provides another basis for having consistent process controls to
ensure quality.
---------------------------------------------------------------------------
\6\ The Agency recognizes that, in limited circumstances, this
may not always be the case; however, for purposes of administrative
efficiency and predictability, the Agency is proposing a bright line
between BLAs and NDAs regarding the referencing of master files for
DS/DSI/DP information for biological products.
---------------------------------------------------------------------------
For these reasons, the Agency considers the establishment and
function of a robust quality assurance program, with intimate knowledge
of all manufacturing steps, to be essential for controlling and
evaluating the process and the biological product, and for mitigating
product quality risks. The applicant for a BLA is expected to have
knowledge of and direct control over the manufacturing process for the
DS/DSI/DP for a biological product (21 CFR 601.2 and 601.20). Absent
this knowledge and control, the applicant generally cannot operate a
robust quality assurance program that independently identifies and
mitigates quality risks, which is critical to assuring the quality of a
biological product.
As a scientific matter, given the complexity of biological
products, the Agency considers it generally impractical for the
applicant to confirm the DS/DSI/DP quality characteristics of a
biological product without complete knowledge of, and control over, all
aspects of the manufacturing process. FDA has concluded that the risk
to quality arising from the fragmentation of information about DS/DSI/
DP for a biological product between a master file and a BLA is very
difficult to mitigate. As a result, FDA believes that this type of
information is generally best submitted to the Agency directly in the
BLA, and that a BLA that incorporates by reference DS/DSI/DP
information for a biological product contained in a master file is
generally inconsistent with biological product licensing
requirements.7 8
---------------------------------------------------------------------------
\7\ FDA may permit, and generally will continue to permit, an
applicant to incorporate by reference certain information about a
product that is not the subject of the applicant's own BLA, such as
information about a comparator product used in studies intended to
support approval of the applicant's BLA. Incorporation of such
information by reference generally does not raise similar concerns
relating to an applicant's knowledge and control over all aspects of
the manufacturing process for the product that is the subject of the
applicant's own BLA.
\8\ In lieu of the use of master files, other types of contract
manufacturing arrangements can be considered if the sponsor does not
intend to manufacture all aspects of the product for licensure and
the licensee assumes responsibility for compliance with the
applicable product and establishment standards. (See, e.g., FDA
guidance for industry entitled ``Cooperative Manufacturing
Arrangements For Licensed Biologics,'' November 2008, available at
https://www.fda.gov/ucm/groups/fdagov-public/@fdagov-bio-gen/documents/document/ucm069908.pdf (accessed March 2019).)
---------------------------------------------------------------------------
Accordingly, proposed Sec. 601.2(g) would codify FDA's
longstanding practice of not permitting a biological product in a BLA
to incorporate by reference information regarding DS/DSI/DP contained
in master files.
3. The Biologics Price Competition and Innovation Act of 2009
Section 7002(b) of the BPCI Act amended, in part, the definition of
a ``biological product'' in the PHS Act to include a ``protein (except
any chemically synthesized polypeptide).'' \9\ Accordingly, under
section 351(i) of the PHS Act, a ``biological product'' is now defined
as ``a virus, therapeutic serum, toxin, antitoxin, vaccine, blood,
blood component or derivative, allergenic product, protein (except any
chemically synthesized polypeptide), or analogous product, or
arsphenamine or derivative of arsphenamine (or any other trivalent
organic arsenic compound), applicable to the prevention, treatment, or
cure of a disease or condition of human beings'' (section 351(i) of the
PHS Act; emphasis added).
---------------------------------------------------------------------------
\9\ See footnote 1.
---------------------------------------------------------------------------
Some protein products have historically been approved under section
505 of the FD&C Act. However, section 7002(e) of the BPCI Act provides
that a marketing application for a ``biological product'' must be
submitted under section 351 of the PHS Act (subject to certain
exceptions during a transition period ending on March 23, 2020).
Section 7002(e) of the BPCI Act also provides that, on March 23, 2020,
an application for a biological product approved under section 505 of
the FD&C Act ``shall be deemed to be a license for a biological product
under section 351'' of the PHS Act.\10\ Such approved applications are
referred to as ``deemed BLAs'' in this document.
---------------------------------------------------------------------------
\10\ See FDA Guidance for Industry entitled ``Interpretation of
the `Deemed to be a License' Provision of the Biologics Price
Competition and Innovation Act of 2009'' (December 2018). Available
at https://www.fda.gov/downloads/Drugs/GuidanceComplianceRegulatoryInformation/Guidances/UCM490264.pdf
(accessed March 2019).
---------------------------------------------------------------------------
C. Need for the Regulation
1. The Biologics Price Competition and Innovation Act of 2009 and the
Use of Drug Master Files in BLAs
The BPCI Act is silent about implementation of the ``deemed to be a
license for a biological product'' provision. In March 2016, FDA
published a draft guidance for industry entitled ``Interpretation of
the `Deemed to be a License' Provision of the Biologics Price
Competition and Innovation Act of 2009'' (see 81 FR 13373, March 14,
2016). Footnote 12 of that draft guidance explained that for sponsors
of proposed protein products who intend to submit a BLA, a Type II DMF
for a drug substance, drug substance intermediate, or drug product
would not be acceptable for a BLA
[[Page 30972]]
because a license holder is expected to have knowledge of and control
over the manufacturing process for the biological product for which it
has a license. The footnote went on to provide that FDA is considering
a mechanism that, in limited circumstances, would allow holders of
approved applications under section 505 of the FD&C Act that reference
a Type II DMF to continue to reference the DMF after the application is
deemed to be a license under the PHS Act on March 23, 2020. FDA
finalized this guidance in December 2018 (available at https://www.fda.gov/downloads/Drugs/GuidanceComplianceRegulatoryInformation/Guidances/UCM490264.pdf (accessed March 2019)), after considering
comments in its draft recommendations and without including the
corresponding footnote from the draft guidance because this proposed
rule would establish such a mechanism, while also codifying the general
longstanding practice that BLAs and INDs for biological products can
reference information in master files except, in the case of BLAs, for
DS/DSI/DP information for a biological product.
2. Mechanism To Permit the Continued Use of Currently Referenced DMFs
by ``Deemed BLAs''
Biological products regulated under the FD&C Act have been able to
incorporate by reference DS/DSI/DP information contained in DMFs to
support the approval of NDAs. As explained above, for biological
products licensed under section 351 of the PHS Act, incorporating by
reference information contained in master files on DS/DSI/DP generally
is not permitted.
This proposed regulation addresses, in part, a specific issue
related to implementation of the ``deemed to be a license'' provision
of the BPCI Act: Whether applications approved under section 505 of the
FD&C Act may continue to incorporate by reference DS/DSI/DP information
contained in DMFs once the applications are deemed to be BLAs subject
to licensure and regulation under the PHS Act.
To date, FDA has identified approximately 89 applications approved
under the FD&C Act that will be deemed licensed under the PHS Act on
March 23, 2020. Approximately 17 of these applications incorporate by
reference information on DS/DSI/DP contained in DMFs. Furthermore, the
DS/DSI/DP information incorporated by reference into these 17
applications is drawn from only 7 DMFs. Thus, this use of DMFs for DS/
DSI/DP information involves a small subset of the deemed BLAs and only
a very small number of DMFs.
In light of FDA's longstanding practice of not permitting a
biological product in a BLA to incorporate by reference information
regarding DS/DSI/DP contained in a master file, the Agency is
considering the appropriate regulatory approach to the relatively few
deemed BLAs that reference DS/DSI/DP information contained in DMFs. The
Agency is evaluating the risks and benefits of allowing these deemed
BLAs to continue incorporating by reference this type of information
from those DMFs. The analysis takes into account clinical
considerations and product availability, as well as the limited number
of applications and the limited number of DMFs that are involved. Based
on this analysis, the Agency proposes that for biological products, the
appropriate mechanism with respect to addressing incorporation by
reference of DS/DSI/DP information contained in DMFs would be to
implement the least disruptive approach.
Some of the deemed BLAs that currently incorporate by reference
information contained in DMFs to support the application were approved
by the Agency based in part on DS/DSI/DP information contained in those
DMFs. Many of these products have been marketed for decades. Over this
period, none of these products have been withdrawn or removed from the
market for reasons of safety or effectiveness. For these products, the
Agency has no reason to believe that the March 23, 2020, transition in
and of itself introduces new risks to product safety, purity, and
potency.
For some biological products, such as certain reproductive
hormones, treating the deemed BLAs like other applications for
biological products under the PHS Act with regard to the use of DS/DSI/
DP information contained in a DMF would present a considerable
challenge. Nearly all approved applications for these biological
products incorporate by reference DS/DSI/DP information contained in a
DMF. This incorporation by reference has resulted in drug substances
for these products of acceptable quality for decades. For example,
multiple Human Chorionic Gonadotropins from urinary sources have been
on the market since the mid-1970s using DMFs for information on the
drug substance, with changes to the product being handled through the
DMF pathway. Disallowing use of DMFs for these deemed BLAs would
curtail or halt production of these products, resulting in imminent or
immediate drug shortages with considerable negative impacts on public
health. FDA does not believe it was Congress's intent when enacting
section 7002(e) of the BPCI Act that deemed BLAs would need to be
removed from the market on March 23, 2020.
Furthermore, the general concern about fragmentation of DS/DSI/DP
information associated with the use of DMFs is lessened in the case of
the deemed BLAs by the existence of generally longstanding
relationships between the deemed-BLA applicants and the DMF holders.
For example, the license holder of a deemed BLA may have accumulated
knowledge about the quality of the biological product supplied by the
DMF holder over an extended period. This accumulated knowledge allows
the deemed BLA holder to implement a more robust control strategy to
mitigate the risk to product quality posed by the applicant's limited
knowledge of the manufacturing process described in the DMF.
In light of these facts, FDA believes that permitting a limited
number of deemed BLAs to continue to incorporate by reference DS/DSI/DP
information contained in a limited number of DMFs will, on balance,
protect and promote the public health. In contrast, if non-deemed BLAs
were to reference an existing DMF, they would generally not have the
benefit of this accumulated knowledge, and thus would not be able to
mitigate the resulting fragmentation of information and risk to product
quality as effectively. Similarly, while the lack of overt safety
signals and the absence of concerns about efficacy provide a rationale
for allowing a deemed BLA to continue to rely on DS/DSI/DP information
contained in a DMF, it may not be appropriate to extend this rationale
to a non-deemed BLA. For these reasons, in proposed Sec. 601.2(h), FDA
would permit only deemed BLAs that incorporate by reference information
on DS/DSI/DP contained in particular DMFs in their approved
applications under section 505 of the FD&C Act to continue doing so
after these products are deemed to be licensed under the PHS Act on
March 23, 2020. BLAs for other biological products will continue to not
be permitted to incorporate by reference DS/DSI/DP information
contained in a master file, consistent with FDA's longstanding
practice. Also, to enable innovation for deemed BLAs that reference an
existing DMF, it is important to preserve the ability to make changes
to the existing DMFs. Therefore, the proposed rule will permit holders
of existing DMFs referenced for deemed BLAs before transition to modify
these DMFs under Sec. 314.420 after March 23, 2020.
[[Page 30973]]
3. Investigational New Drug Applications and Master Files
Section 314.420(b) provides that ``[a]n investigational new drug
application . . . may incorporate by reference all or part of the
contents of any drug master file in support of the submission'' with
the DMF holder's consent. In addition, FDA typically permits an IND for
a biological product to incorporate by reference information contained
in other master files, in addition to DMFs. Furthermore, it has been
FDA's practice to permit sponsors of INDs for biological products to
incorporate by reference DS/DSI/DP information contained in a master
file.
FDA permits the use of DS/DSI/DP master files in biological product
INDs for several reasons. Exposure to the investigational product is
limited in the IND stage because it is only administered to subjects
enrolled in clinical trials, which are typically carried out in
controlled settings. Accordingly, the sponsor and FDA can mitigate risk
more effectively by closely monitoring patients in those trials, in
order to evaluate the safety of the investigational product, which is a
necessary component of the licensing process.
Permitting the sponsor of an IND for a biological product to
incorporate by reference DS/DSI/DP information contained in master
files may also facilitate product development. Without this option, a
sponsor might choose not to make the significant investment to
manufacture the necessary DS/DSI/DP for a biological product at this
early stage of development. However, even in cases where an IND sponsor
of a biological product incorporates by reference DS/DSI/DP information
contained in a master file, FDA expects the sponsor to have knowledge
of and direct control of the manufacturing process by later stages of
development.
Therefore, in proposed Sec. 601.2(j), FDA clarifies and codifies
this practice.
D. History of the Rulemaking
In response to the BPCI Act, public meetings were held to discuss
various aspects of the statute. Also, public comments on the current
FDA practice for biological products of not accepting DMFs for
biological products in BLAs were received in the context of the draft
guidance for industry entitled ``Interpretation of the `Deemed to be a
License' Provision of the Biologics Price Competition and Innovation
Act of 2009'' (see 81 FR 13373). Comments, in part: (1) Urged FDA to
clarify its position on the use of Type II DMFs for applications that
will be deemed BLAs on March 23, 2020, and, at least for pancreatic
enzyme products, recommended FDA permit applications to reference Type
II DMFs after March 23, 2020, even if the application was not approved
as an NDA prior to the transition date; \11\ (2) urged FDA to adopt a
flexible approach toward the continued referencing of existing DMFs;
\12\ and (3) sought clarity on the use of other categories of DMFs
(e.g., Type III DMFs).\13\ FDA finalized this guidance in December 2018
after considering comments in its draft recommendations. With respect
to the comments concerning DMFs, the Agency undertook an analysis of
the number of DMFs, the number of applications referencing these DMFs,
and considered the consequences of not taking any action or taking the
proposed action. The Agency addressed all the concerns identified in
the public comments through the actions described in this proposed
rule, which includes allowing the incorporation by reference of DS/DP/
DSI information contained in DMFs, provided the DMFs were referenced
prior to the application being deemed a BLA on March 23, 2020, and
providing clarity on the use of other categories of DMFs in BLAs.

---------------------------------------------------------------------------
IV. Legal Authority
FDA is proposing to amend its regulations, in part, to implement
certain aspects of section 7002(e) of the BPCI Act. FDA's authority for
this proposed rule also derives from the biological product licensing
provisions of the PHS Act and the provisions of the FD&C Act (21 U.S.C.
321, et seq.) applicable to drugs. Under these provisions, FDA has the
authority to issue regulations designed to ensure, among other things,
that biological products are safe, pure, and potent and manufactured in
accordance with current good manufacturing practice. FDA also has
general authority to promulgate regulations for the efficient
enforcement of the FD&C Act and the PHS Act, under section 701 of the
FD&C Act and section 351(j) of the PHS Act.
V. Description of the Proposed Rule
We propose to amend Sec. 601.2 to add new paragraphs (g), (h),
(i), and (j). Specifically, the proposed rule will allow applications
for biological products approved under section 505 of the FD&C Act to
continue to incorporate by reference DS/DP/DSI information contained in
DMFs, provided the DMFs were referenced before March 23, 2020. Also,
this proposed rule essentially codifies, for biological products, the
longstanding Agency practices of permitting BLAs to incorporate by
reference information other than on DS/DP/DSI contained in master files
and INDs to incorporate any information contained in master files. FDA
is aware that there are combination products approved in BLAs under the
PHS Act and considers that the rationale described in this rule for
biological products also applies to the biological constituent part of
such combination products. FDA seeks comments on whether applications
for combination products submitted in BLAs under the PHS Act should be
permitted to incorporate by reference DS/DSI/DP information for any
non-biological constituent part (for example, the drug constituent part
of an antibody drug conjugate).
A. Proposed Provision of Paragraph (g)
Proposed new paragraph (g) codifies the Agency's practice of not
permitting applications for biological products submitted under section
351 of the PHS Act to incorporate by reference information on DS/DSI/DP
contained in a master file. Deemed BLAs are excluded from this
provision and are addressed in proposed new paragraph (h).
B. Proposed Provision of Paragraph (i)
Proposed new paragraph (i) codifies the Agency's practice of
permitting applications for biological products submitted under section
351 of the PHS Act to incorporate by reference information other than
DS/DSI/DP information contained in master files, including in DMFs.
C. Proposed Provision of Paragraph (j)
Proposed new paragraph (j) codifies the Agency's practice of
permitting INDs to incorporate by reference information contained in
master files, including information on DS/DSI/DP.
D. Proposed Provision of Paragraph (h)
Proposed new paragraph (h) addresses applications transitioning on
March 23, 2020, under section 7002(e) of the BPCI Act. It allows an
application for a biological product that has been approved under
section 505 of the FD&C Act and that incorporates by reference DS/DSI/
DP information contained in a DMF to continue to do so after that
application is deemed to be a BLA.
[[Page 30974]]
The proposed rule is intended to preserve the status quo both for
the small number of deemed BLAs and for all other applications for
biological products submitted under section 351 of the PHS Act: Deemed
BLAs that incorporate by reference information on DS/DSI/DP contained
in a DMF at the time of their transition will be permitted to continue
to do so, but no other applications for biological products will be
permitted to incorporate by reference DS/DSI/DP information contained
in any master files.
The proposed rule is not intended to alter a license holder's
ability to modify a product under Sec. 601.12 (21 CFR 601.12). The
proposed rule is also not intended to expand or reduce the changes
allowed to a deemed BLA that incorporates by reference information
contained in master files. Under the proposed rule, an applicant would
be permitted to supplement a deemed BLA within the same application, as
it would any other BLA under Sec. 601.12 and the applicable bundling
policy.\14\ However, if modifications to the deemed BLA are required
that could not be effected in a supplement and a new application is
required, that new BLA would not be considered a deemed BLA. As is the
case with other (non-deemed) applications for biological products, the
new BLA would not be permitted to reference DS/DSI/DP information
contained in any master file and would need to submit this information
as part of the new BLA itself.
---------------------------------------------------------------------------
\14\ See guidance for industry entitled ``Submitting Separate
Marketing Applications and Clinical Data for Purposes of Assessing
User Fees'' (December 2004). Available at https://www.fda.gov/ucm/groups/fdagov-public/@fdagov-drugs-gen/documents/document/ucm079320.pdf. (accessed March 2019).
---------------------------------------------------------------------------
The proposed rule is also not intended to limit or restrict the
changes that may be made to any master file, including a DMF for DS/
DSI/DP information.
The proposed rule thus preserves the relationship between a DMF and
the application that references it. This ensures that the transition to
regulation under the PHS Act does not interrupt the supply of
biological products that have already been shown to be safe and
effective.
E. Proposed Records/Record Retention Requirements
None; existing records and retention requirements will continue to
apply.
F. Proposed Enforcement Provisions
None; existing enforcement regulations will continue to apply.
G. Proposed Technical/Conforming Amendments
None necessary.
VI. Proposed Effective/Compliance Dates
If finalized on or before February 22, 2020, this rule would take
effect on March 23, 2020.
VII. Preliminary Economic Analysis of Impacts
We have examined the impacts of the proposed rule under Executive
Order 12866, Executive Order 13563, Executive Order 13771, the
Regulatory Flexibility Act (5 U.S.C. 601-612), and the Unfunded
Mandates Reform Act of 1995 (Pub. L. 104-4). Executive Orders 12866 and
13563 direct us to assess all costs and benefits of available
regulatory alternatives and, when regulation is necessary, to select
regulatory approaches that maximize net benefits (including potential
economic, environmental, public health and safety, and other
advantages; distributive impacts; and equity). Executive Order 13771
requires that the costs associated with significant new regulations
``shall, to the extent permitted by law, be offset by the elimination
of existing costs associated with at least two prior regulations.'' We
believe that this proposed rule is not a significant regulatory action
as defined by Executive Order 12866.
The Regulatory Flexibility Act requires us to analyze regulatory
options that would minimize any significant impact of a rule on small
entities. Because the proposed rule does not impose any new burdens, we
propose to certify that the proposed rule will not have a significant
economic impact on a substantial number of small entities.
The Unfunded Mandates Reform Act of 1995 (section 202(a)) requires
us to prepare a written statement, which includes an assessment of
anticipated costs and benefits, before proposing ``any rule that
includes any Federal mandate that may result in the expenditure by
State, local, and tribal governments, in the aggregate, or by the
private sector, of $100,000,000 or more (adjusted annually for
inflation) in any one year.'' The current threshold after adjustment
for inflation is $154 million, using the most current (2018) Implicit
Price Deflator for the Gross Domestic Product. This proposed rule would
not result in an expenditure in any year that meets or exceeds this
amount.
Table 1 summarizes our estimate of the annualized costs and the
annualized cost-saving benefits of the proposed rule.

In line with Executive Order 13771, in table 2 we estimate present
and annualized values of costs and cost savings over an infinite time
horizon. Based on these cost savings, this proposed rule would be
considered a deregulatory action under Executive Order 13771.

--------------------------------------------------------------------------------------------------------------------------------------------------------
We have developed a comprehensive Preliminary Economic Analysis of
Impacts that assesses the impacts of the proposed rule. The full
preliminary analysis of economic impacts is available in the docket for
this proposed rule (Ref. 1) and at https://www.fda.gov/AboutFDA/ReportsManualsForms/Reports/EconomicAnalyses/default.htm.
VIII. Analysis of Environmental Impact
We have determined under 21 CFR 25.30(h) that this action is of a
type that does not individually or cumulatively have a significant
effect on the human environment. Therefore, neither an environmental
assessment nor an environmental impact statement is required.
IX. Paperwork Reduction Act of 1995
This proposed rule refers to previously approved collections of
information that 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 21 CFR part 314 and 21 CFR
part 601 have been approved under OMB control numbers 0910-0001 and
0910-0338, respectively.
X. Federalism
We have analyzed this proposed rule in accordance with the
principles set forth in Executive Order 13132. We have determined that
this proposed rule does not contain policies that have substantial
direct effects on the States, on the relationship between the National
Government and the States, or on the distribution of power and
responsibilities among the various levels of government. Accordingly,
we conclude that the rule does not contain policies that have
federalism implications as defined in the Executive Order and,
consequently, a federalism summary impact statement is not required.
XI. Consultation and Coordination With Indian Tribal Governments
We have analyzed this proposed rule in accordance with the
principles set forth in Executive Order 13175. We have tentatively
determined that the rule does not contain policies that would have a
substantial direct effect on one or more Indian Tribes, on the
relationship between the Federal Government and Indian Tribes, or on
the distribution of power and responsibilities between the Federal
Government and Indian Tribes. The Agency solicits comments from tribal
officials on any potential impact on Indian Tribes from this proposed
action.
