SUPPLEMENTARY INFORMATION:
I. Background
In December 2016, the Cures Act
(Pub. L. 114–255) was signed into law.
Section 3038(c) of the Cures Act
mandated that FDA publish in the
Federal Register a list identifying types
of combination products and
manufacturing processes for which
‘‘good manufacturing processes’’ may be
adopted that vary from the requirements
set forth in § 4.4 (21 CFR 4.4) or that
FDA proposes can satisfy the
requirements in § 4.4 through
‘‘alternative or streamlined
mechanisms,’’ and to review this list
periodically. In accordance with this
statutory mandate, FDA is publishing a
proposed list in section II of this
document, which addresses processes
for single-entity and co-packaged
combination products that can satisfy
requirements in § 4.4 through
alternative or streamlined mechanisms
(hereafter ‘‘mechanisms’’).
On January 22, 2013, FDA issued a
final rule on CGMP requirements for
combination products (see 78 FR 4307
and part 4 (21 CFR part 4, subpart A)).
Prior to issuance of the final rule,
although CGMP regulations were in
place to establish requirements for
drugs, devices, biological products, and
human cells, tissues, or cellular or
tissue-based products (HCT/Ps), there
were no regulations to clarify and
explain the application of these CGMP
requirements to combination products.
The final rule clarified which CGMP
requirements apply to combination
products. It also established a
transparent and streamlined regulatory
framework for combination product
manufacturers to use when
demonstrating compliance with
applicable CGMP requirements.
A combination product is a product
composed of two or more different types
of medical products (i.e., a combination
of a drug, device, and/or biological
product). The drugs, devices, and
biological products included in
combination products are referred to as
‘‘constituent parts’’ of the combination
product. Combination products include
‘‘single-entity’’ combination products
that are physically, chemically, or
otherwise combined or mixed and
produced as a single entity (§ 3.2(e)(1)
(21 CFR 3.2(e)(1)) (e.g., prefilled
syringes and drug-eluting stents) and
‘‘co-packaged’’ combination products
where two or more separate products
are packaged together in a single
PO 00000

package or as a unit and composed of
drug and device products, device and
biological products, or biological and
drug products (§ 3.2(e)(2)) (e.g., a
surgical or first-aid kit).1 Section 4.4
outlines how manufacturers of singleentity and co-packaged combination
products (hereafter ‘‘CP manufacturers’’)
can demonstrate compliance with
applicable CGMP requirements,
including through implementation of a
streamlined approach to meet the
requirements of both the drug CGMP
and the device Quality System (QS)
regulation by designing and
implementing a CGMP operating system
that demonstrates compliance with
either of the following:
• The drug CGMP regulations in parts
210 and 211 (21 CFR parts 210 and 211)
and the following specified provisions
from the device QS regulation
(§ 4.4(b)(1), ‘‘drug CGMP-based
streamlined approach’’): (1) § 820.20 (21
CFR 820.20) Management responsibility,
(2) § 820.30 (21 CFR 820.30) Design
controls, (3) § 820.50 (21 CFR 820.50)
Purchasing controls, (4) § 820.100 (21
CFR 820.100) Corrective and preventive
action, (5) § 820.170 (21 CFR 820.170)
Installation, and (6) § 820.200 (21 CFR
820.200) Servicing; or
• The device QS regulation in part
820 (21 CFR part 820) and the following
specified provisions from the drug
CGMP regulations (§ 4.4(b)(2), ‘‘device
QS regulation-based streamlined
approach’’): (1) § 211.84 (21 CFR 211.84)
Testing and approval or rejection of
components, drug product containers,
and closures; (2) § 211.103 (21 CFR
211.103) Calculation of yield; (3)
§ 211.132 (21 CFR 211.132) Tamperevident packaging requirements for
1 There are also ‘‘cross-labeled’’ combination
products (§ 3.2(e)(3) and (4)). With respect to crosslabeled combination products, part 4, subpart A
was intended to clarify only that the CGMP
requirements applicable to the drugs, devices, or
biological products also apply to these types of
articles when they are constituent parts of such
combination products. Constituent parts of crosslabeled combination products need only comply
with the requirements otherwise applicable to that
type of product (e.g., 21 CFR parts 210 and 211 for
a drug constituent part or 21 CFR part 820 for a
device constituent part). The ‘‘streamlined
approach’’ and related mechanisms described in
this notice are generally not relevant or applicable
to cross-labeled combination products. However, to
the extent that the constituent parts of a crosslabeled combination product are manufactured at
the same facility, the manufacturing process would
be akin to when the manufacture of the constituent
parts of a co-packaged combination product occurs
at the same facility. Accordingly, as discussed in
the combination product CGMP guidance (Ref. 1),
for cross-labeled combination products
manufactured at the same facility, the Agency does
not intend to object to the use of a streamlined
CGMP operating system for the manufacture of the
combination product rather than distinct systems
for the manufacture of each constituent part that is
occurring at that facility.

(21 CFR 211.167) Special testing
requirements; and (8) § 211.170 (21 CFR
211.170) Reserve samples.
If the combination product includes a
biological product constituent part, the
CGMP operating system must also
demonstrate compliance with
applicable CGMP requirements for
biological products in parts 600 through
680 (21 CFR parts 600 through 680), and
if the combination product includes an
HCT/P, the CGMP operating system
must also demonstrate compliance with
the applicable current good tissue
practice requirements in part 1271 (21
CFR part 1271).
Following publication of the final
rule, FDA reviewed data and rationales
provided by manufacturers who
proposed various means of addressing
CGMP considerations for combination
products. FDA also considered feedback
on its draft guidance on CGMP
requirements for combination products,
published in January 2015, in which
stakeholders requested further guidance
on circumstances in which flexible
approaches may be available and how to
engage with FDA on them. The final
‘‘Guidance for Industry and FDA Staff:
Current Good Manufacturing Practice
Requirements for Combination
Products’’ includes discussion of
existing mechanisms to comply with the
final rule and of circumstances in which
FDA did not intend to object to
manufacturers applying practices that
vary from the requirements set forth in
the rule (Ref. 1). The Agency continues
to apply a risk-based approach to
evaluating methods for ensuring the
quality of combination products and to
welcome proposals from manufacturers
for how to enhance the efficiency of
development and manufacturing
activities, while ensuring the safety and
effectiveness of the combination
products produced.

II. Proposed List of Mechanisms for
Complying With § 4.4 CGMP
Requirements for Combination
Products
A. Introduction
The following is a proposed list of
mechanisms for demonstrating
compliance with relevant combination
product CGMP requirements, as
described below. Where applicable,
reference is made to sections of the
‘‘Guidance for Industry and FDA Staff:
Current Good Manufacturing Practice
VerDate Sep<11>2014
18:01 Jun 12, 2018
Jkt 244001
Requirements for Combination
Products’’ for additional information
(Ref. 1). FDA will continue to evaluate
this list in light of Agency experience
and stakeholder input. Manufacturers
are welcome to propose other
approaches not described, and FDA
continues to encourage dialogue with
the Agency on various means of
demonstrating CGMP compliance for
combination products.
For each mechanism described below,
CP manufacturers should consider what
documentation would be sufficient to
support that the mechanism, including
the specific approach for implementing
it, assures appropriate control of the
manufacture of the combination product
to ensure safety and effectiveness of the
product. Appropriate evidence and an
explanation of the rationale to support
the approach should be accessible at the
manufacturing facility for review during
facility inspections. For additional
discussion on how to interact with FDA
regarding the mechanisms described
below, see section III.
B. Mechanisms for Complying With
Drug CGMP Requirements (Part 211)
Specified in § 4.4 2
FDA interprets the mechanisms
identified in the sections below as a
means to demonstrate compliance with
the specified part 211 requirements
identified in § 4.4:
1. Section 211.165 Testing and Release
for Distribution
Use of product samples that are not
finished combination products (but that
are representative of the finished
combination product with respect to the
characteristics and attributes being
tested) when performing testing required
by § 211.165 to determine whether the
drug constituent part meets final
specifications. To meet the requirements
of § 211.165, the CP manufacturer
would need to establish, including
where appropriate through bridging
studies and other quantitative means,
that any differences in the
manufacturing process for the
representative samples as compared to
the finished combination product do not
affect the drug constituent part. For
example, as part of product release
testing, drug-eluting lead manufacturers
could perform release testing for
identity, potency, or other quality
attributes on a representative lead tip
2 Several drug CGMP mechanisms included in
this proposed list depend upon use of a more
broadly defined batch. FDA notes that approaches
that depend upon broadly defined batches may
increase the number of distributed products
implicated when corrective actions are necessary to
address postmarket issues.

assembly that contains the drug
constituent part, but does not contain
the full electronic and mechanical
assembly, so long as they can establish
that the differences in the
manufacturing process do not impact
the drug constituent part and the sample
is representative of the finished
combination product with respect to the
quality attributes being tested.
(See also Section IV.B.5 of Reference
1 for additional information on testing
and release for combination products.)
2. Section 211.166
Stability Testing
Use of bracketing and matrixing
approaches to stability studies for
combination products. Principles for
bracketing and matrixing approaches to
meet the requirements of § 211.166 have
already been addressed by the Agency
with regard to drug products (Ref. 2),
and such principles can also be applied
to combination products. For example,
when assessing stability for a prefilled
syringe that is marketed in various fill
volumes, one of the approaches that a
CP manufacturer could utilize, if
appropriate, is bracketing based on the
smallest and the largest fill volume of
product configurations. In determining
the extremes for a bracketing approach
and/or when justifying the use of a
matrix design for single-entity
combination products, it is important
that the drug-device interactions and
variations in the manufacturing
processes are considered. For copackaged combination products, such
approaches can be applied to the drug
constituent part of the product.
Leveraging stability data for an
already marketed combination product.
Such mechanisms can be considered
when the new combination product is a
modification of an already marketed
product and the modification does not
impact the stability of the drug
constituent part. For example, when
developing new lengths of a drug-coated
catheter product for which the catheter
materials, drug coating, manufacturing
process, and packaging configurations
are largely unchanged from existing
marketed sizes, the CP manufacturer
would generally be able to leverage
existing stability data to establish initial
product shelf life or to support reduced
stability data requirements, so long as
characteristics of the product that could
impact stability (materials, packaging
configuration, etc.) remain the same.
However, if the device constituent part
of a drug-coated catheter includes a new
material that is in contact with the drug
coating, for example, new stability
studies would generally be needed
under § 211.166.

(See also Section IV.B.6 of Reference
1 for additional information on stability
requirements for combination products.)
amozie on DSK3GDR082PROD with NOTICES1
3. Section 211.167 Special Testing
Requirements
Defining ‘‘batch’’ based on the drug
constituent part rather than the finished
combination product for purposes of
special testing requirements for
pyrogens and endotoxins. For example,
a manufacturer of a combination
product that has a sub-assembly coated
with a drug, which is then incorporated
into several ‘‘batches’’ or ‘‘lots’’ of the
overall combination product, may be
able to define a batch for purposes of
pyrogen and endotoxin testing as a
batch of that sub-assembly for purposes
of meeting the requirements of
§ 211.167. As with the other
mechanisms described in this list, this
mechanism would only potentially be
available if there would be no impact on
the drug constituent part from
subsequent manufacturing processes,
including when the constituent parts are
combined to produce the final
combination product. CP manufacturers
should consider whether such risks may
be introduced later in the production
process (after the batch has been
defined). This approach will most
frequently apply for co-packaged
combination products or single-entity
combination products for which only a
component or sub-assembly of the
overall product is in contact with the
drug constituent part.
(See also Section IV.B.7 of Reference
1 for additional information on special
testing requirements for combination
products.)
4. Section 211.170 Reserve Samples
Keeping reserve samples that are
representative of the finished
combination product. CP manufacturers
may use validated surrogates as
representative samples to meet the
requirements of § 211.170, provided the
surrogate is appropriate, both in terms
of the manufacturing process and the
characteristics of the container closure.
For example, maintaining only a subassembly of a coated single-entity
combination product or only the drug
constituent part of a co-packaged
combination product as a reserve
sample would generally be permissible
under the regulation when: (1) All
manufacturing process steps after the
coating step or the fill for the drug
constituent part are shown not to affect
the drug constituent part, (2) the
immediate container closure has
essentially the same characteristics as
that for the drug constituent part as
packaged in the combination product
VerDate Sep<11>2014

Jkt 244001
for distribution, and (3) the
representative samples are suitable for
all required testing of the drug
constituent part for which the reserve
samples are being kept.
Using samples from representative
lots of a larger batch for retention of
reserve samples. To meet the
requirements of § 211.170, CP
manufacturers may be able to use
bracketing and matrixing approaches to
retain reserve samples from certain lots
to adequately represent the broadly
defined batch of the combination
product. For example, CP manufacturers
might be able to retain reserve samples
of appropriately varied sizes of a drugcoated combination product from
within a broadly defined batch that
includes multiple lots of different sizes.
(See also Section IV.B.8 of Reference
1 for additional information on reserve
sample requirements for combination
products.)
C. Mechanisms for Complying With
Device Quality System Requirements
(Part 820) Specified in § 4.4
FDA interprets the mechanisms
identified in the sections below as a
means to demonstrate compliance with
the specified part 820 requirements
identified in § 4.4:
1. Section 820.30 Design Controls
Using existing pharmaceutical
development practices and
documentation that align with the
design control principles and
requirements of § 820.30. Robust
pharmaceutical development practices
would address many design control
requirements to assure compliance with
§ 820.30, where applicable. CP
manufacturers need to demonstrate how
development processes and terminology
align with design control principles and
requirements in § 820.30, when
required, including, where necessary,
developing additional design control
elements. When evaluating the
adequacy of existing pharmaceutical
development processes, particular
attention should be given to postmarket
management of design changes to the
combination product and the alignment
of change control practices with the
principles and requirements of § 820.30,
as applicable.
2. Exemption of Combination Products
From Device QS Regulation
Exemption of the combination
product from all or certain provisions of
the device QS regulation (part 820) if
the device constituent part of the
combination product is itself exempt
from such requirements and use of the
device constituent part falls within the
PO 00000
Frm 00075
Fmt 4703
Sfmt 4703
scope of the relevant exemption,
including with respect to the device
constituent part’s intended use. Some
devices are exempt from all or certain
provisions of the device QS regulation
(see, for example, liquid medication
dispensers such as cups and droppers
that fall within the scope of § 880.6430
(21 CFR 880.6430), provided the use of
the device is not a new intended use or
does not otherwise raise different safety
and effectiveness questions (see, for
example, limitations to the exemption
under 21 CFR 880.9). Consistent with
this, for the combination product to be
exempt from the associated provisions
of the device QS regulation, we interpret
this exemption to mean that the use of
the device in the combination product
must not be a new intended use or
otherwise raise different safety and
effectiveness questions for the device.
This circumstance will most frequently
apply to co-packaged combination
products. For example, an oral dosing
syringe (a liquid medication dispenser
under § 880.6430) that is co-packaged
with a drug may be exempt from certain
provisions of the device QS regulation
(and hence the combination product
may also be exempt from such
provisions); however, incorporation of
such a dispenser into a primary
container closure system or copackaging of such a dispenser with an
emergency-use product, for example,
may constitute a new intended use for
the dispenser or raise different safety
and effectiveness questions for the
dispenser, such that the relevant
exemption would not apply.
(See also Section III.C.3 of Reference
1 for additional information on the
exemption from provisions of the device
QS regulation for combination
products.)
III. Interacting With FDA on
Mechanisms for Complying With CGMP
for Combination Products
1. Process for Interacting With FDA
In some cases, CP manufacturers may
interact with FDA to gain approval or
otherwise notify FDA of a
manufacturing change. In other cases,
although a submission or notification is
not required, CP manufacturers may
want to discuss potential use of CGMP
mechanisms with FDA. CP
manufacturers are encouraged to
interact early with FDA on
contemplated CGMP mechanisms.
• Pre-Submissions and Meeting
Requests. CP manufacturers who want
to obtain FDA feedback prior to
submitting a premarket application or a
postmarket supplement or who
otherwise want to obtain feedback on

their approach may interact with FDA
via the existing established process
applicable to the lead Center 3 for the
combination product. For combination
products reviewed under a new drug
application (NDA) or a biologics license
application (BLA), such interactions
will generally be through Type C
meetings (Ref. 3).4 For combination
products reviewed under an abbreviated
new drug application (ANDA), these
interactions will generally be through
pre-ANDA meetings (Ref. 4).5 For
combination products reviewed under a
device premarket submission (e.g., a
premarket approval application (PMA),
de novo classification, or premarket
notification (510(k)), these interactions
will generally be via the pre-submission
process (Ref. 5).
Regardless of the type of submission,
such interactions should be focused on
a general discussion of the mechanism
and CGMP approach the CP
manufacturer wishes to pursue and
associated justification to support the
approach. Only representative data is
typically appropriate in these
interactions; complete data should be
included in the subsequent premarket
submission or postmarket supplement,
if required, and/or be maintained at the
manufacturing facility, as appropriate.6
• Premarket Review. CP
manufacturers should include in their
original submission for NDAs, BLAs,
ANDAs, and PMAs information on any
mechanisms for complying with CGMP
requirements. For PMAs, this
information should be included in the
manufacturing section of the PMA. For
information regarding where to place
information in NDAs, BLAs, or ANDAs,
refer to ‘‘eCTD Technical Conformance
Guide’’ (Ref. 6).

center (Center for Biologics Evaluation and
Research, Center for Drug Evaluation and Research,
or Center for Devices and Radiological Health) that
will have primary jurisdiction (i.e., the ‘‘lead
Center’’) for that combination product’s review and
regulation. Assignment of a combination product to
a lead Center is based on a determination of which
constituent part provides the primary mode of
action of the combination product (21 U.S.C.

6 Note that when discussing a mechanism for
complying with CGMP requirements for which the
CP manufacturer is leveraging information in
master file(s), the master file holder must submit a
letter of authorization to permit FDA to review such
information (see 21 CFR 314.420(d) and 21 CFR
814.20(c)). The specific information within the
master file that is being leveraged should be clearly
identified to FDA.

product CGMP mechanism for NDAs,
ANDAs, BLAs, and PMAs, may require
submission of a supplement or
notification to FDA.7 CP manufacturers
should consult related guidances
relevant to the type of constituent part
of the combination product (Refs. 7 to
9).8 If a CP manufacturer has questions
on the appropriate submission type or
the need for a submission, they can
contact the lead Center for assistance.
2. Content Suggestions
When submitting information on a
CGMP mechanism, along with any
submission requirements applicable to
the submission type, the following
content should be included:
• Applicable CGMP regulation.
Identify the CGMP regulation applicable
to the described mechanism. For
example, if a submission includes a
mechanism related to stability testing,
indicate that § 211.166 is the applicable
CGMP requirement.
• Applicable Products. If the
mechanism is to be applied to multiple
products and/or product configurations,
list all related sizes, strengths, etc., as
well as all related application numbers.
• Related Interactions with FDA. If
the CP manufacturer has had previous
interactions with FDA relevant to the
proposed mechanism, either for the
product addressed in the submission or
for related products, the CP
manufacturer should provide reference
to those interactions. Where applicable,
the CP manufacturer may crossreference previously submitted
information.
• Justification and Scientific Data.
Include a rationale to support that the
proposed mechanism assures adequate
manufacturing control to ensure product
safety and effectiveness. When
describing a CGMP mechanism in a
premarket or postmarket submission,
the description should be accompanied
by data necessary to support the
approach. When proposing a change
from a CGMP approach that was
reviewed previously by FDA, such
justification should include analysis of
how the proposed approach compares to
the previously reviewed approach as an
effective manufacturing control,
including representative data, as
appropriate, to substantiate the analysis.
7 Requirements for postmarket supplements are
contained, for example, in 21 CFR 314.70 (NDAs),
21 CFR 601.12 (BLAs), and 21 CFR 814.39 (PMAs).
Any questions on whether FDA review is required
for a postmarket CGMP mechanism should be
directed to the lead Center.
8 With reference to Ref. 8, when final, this
guidance will represent the FDA’s current thinking
on this topic.

3. FDA Engagement
CP manufacturers are encouraged to
discuss combination product CGMP
mechanisms with FDA. Any questions
on how to engage FDA in such
discussions should be directed to the
lead Center for the product or the Office
of Combination Products, as needed.
4. FDA Review
FDA may review information from a
CP manufacturer related to a mechanism
for complying with CGMP requirements
for combination products in premarket
applications, postmarket supplements
or notifications, pre-submissions and
meetings, and during facility
inspections. FDA may determine that
the data and rationale presented by a CP
manufacturer for a particular
mechanism are insufficient to
demonstrate that the mechanism, as
proposed or implemented, meets the
applicable CGMP requirement. FDA
generally will notify the CP
manufacturer and/or applicant in
writing of any such determination.
IV. Other Issues for Consideration
We have developed this proposed list
of mechanisms based on information
submitted to FDA by CP manufacturers
as well as FDA experience with
manufacturing processes and CGMP
compliance approaches that have been
shown through appropriate data and
rationales to support the manufacture of
safe and effective products. FDA
requests comment from stakeholders
who believe there are additional types
of combination products and/or
manufacturing processes where
different approaches may be
appropriate. When providing such
feedback, the suggested approach
should be:
• Applicable to a type or range of
combination products (e.g., not just a
single CP manufacturer’s product).
Commenters should indicate to which
types of combination products or
manufacturing processes they believe
the suggested approach should apply.
• Supported by adequate data and
rationales to demonstrate that such an
approach would continue to support
manufacturing of safe and effective
combination products. Commenters
should summarize the data and
rationale that support the suggested
approach.
Any confidential information submitted
to FDA via the docket should be
appropriately identified (see
Instructions above, in ADDRESSES).

SUPPLEMENTARY INFORMATION:
I. Background
In December 2016, the Cures Act (Pub. L. 114-255) was signed into
law. Section 3038(c) of the Cures Act mandated that FDA publish in the
Federal Register a list identifying types of combination products and
manufacturing processes for which ``good manufacturing processes'' may
be adopted that vary from the requirements set forth in Sec. 4.4 (21
CFR 4.4) or that FDA proposes can satisfy the requirements in Sec. 4.4
through ``alternative or streamlined mechanisms,'' and to review this
list periodically. In accordance with this statutory mandate, FDA is
publishing a proposed list in section II of this document, which
addresses processes for single-entity and co-packaged combination
products that can satisfy requirements in Sec. 4.4 through alternative
or streamlined mechanisms (hereafter ``mechanisms'').
On January 22, 2013, FDA issued a final rule on CGMP requirements
for combination products (see 78 FR 4307 and part 4 (21 CFR part 4,
subpart A)). Prior to issuance of the final rule, although CGMP
regulations were in place to establish requirements for drugs, devices,
biological products, and human cells, tissues, or cellular or tissue-
based products (HCT/Ps), there were no regulations to clarify and
explain the application of these CGMP requirements to combination
products. The final rule clarified which CGMP requirements apply to
combination products. It also established a transparent and streamlined
regulatory framework for combination product manufacturers to use when
demonstrating compliance with applicable CGMP requirements.
A combination product is a product composed of two or more
different types of medical products (i.e., a combination of a drug,
device, and/or biological product). The drugs, devices, and biological
products included in combination products are referred to as
``constituent parts'' of the combination product. Combination products
include ``single-entity'' combination products that are physically,
chemically, or otherwise combined or mixed and produced as a single
entity (Sec. 3.2(e)(1) (21 CFR 3.2(e)(1)) (e.g., prefilled syringes
and drug-eluting stents) and ``co-packaged'' combination products where
two or more separate products are packaged together in a single package
or as a unit and composed of drug and device products, device and
biological products, or biological and drug products (Sec. 3.2(e)(2))
(e.g., a surgical or first-aid kit).\1\ Section 4.4 outlines how
manufacturers of single-entity and co-packaged combination products
(hereafter ``CP manufacturers'') can demonstrate compliance with
applicable CGMP requirements, including through implementation of a
streamlined approach to meet the requirements of both the drug CGMP and
the device Quality System (QS) regulation by designing and implementing
a CGMP operating system that demonstrates compliance with either of the
following:
---------------------------------------------------------------------------
\1\ There are also ``cross-labeled'' combination products (Sec.
3.2(e)(3) and (4)). With respect to cross-labeled combination
products, part 4, subpart A was intended to clarify only that the
CGMP requirements applicable to the drugs, devices, or biological
products also apply to these types of articles when they are
constituent parts of such combination products. Constituent parts of
cross-labeled combination products need only comply with the
requirements otherwise applicable to that type of product (e.g., 21
CFR parts 210 and 211 for a drug constituent part or 21 CFR part 820
for a device constituent part). The ``streamlined approach'' and
related mechanisms described in this notice are generally not
relevant or applicable to cross-labeled combination products.
However, to the extent that the constituent parts of a cross-labeled
combination product are manufactured at the same facility, the
manufacturing process would be akin to when the manufacture of the
constituent parts of a co-packaged combination product occurs at the
same facility. Accordingly, as discussed in the combination product
CGMP guidance (Ref. 1), for cross-labeled combination products
manufactured at the same facility, the Agency does not intend to
object to the use of a streamlined CGMP operating system for the
manufacture of the combination product rather than distinct systems
for the manufacture of each constituent part that is occurring at
that facility.

The drug CGMP regulations in parts 210 and 211 (21 CFR
parts 210 and 211) and the following specified provisions from the

requirements; and (8) Sec. 211.170 (21 CFR 211.170) Reserve samples.
If the combination product includes a biological product
constituent part, the CGMP operating system must also demonstrate
compliance with applicable CGMP requirements for biological products in
parts 600 through 680 (21 CFR parts 600 through 680), and if the
combination product includes an HCT/P, the CGMP operating system must
also demonstrate compliance with the applicable current good tissue
practice requirements in part 1271 (21 CFR part 1271).
Following publication of the final rule, FDA reviewed data and
rationales provided by manufacturers who proposed various means of
addressing CGMP considerations for combination products. FDA also
considered feedback on its draft guidance on CGMP requirements for
combination products, published in January 2015, in which stakeholders
requested further guidance on circumstances in which flexible
approaches may be available and how to engage with FDA on them. The
final ``Guidance for Industry and FDA Staff: Current Good Manufacturing
Practice Requirements for Combination Products'' includes discussion of
existing mechanisms to comply with the final rule and of circumstances
in which FDA did not intend to object to manufacturers applying
practices that vary from the requirements set forth in the rule (Ref.
1). The Agency continues to apply a risk-based approach to evaluating
methods for ensuring the quality of combination products and to welcome
proposals from manufacturers for how to enhance the efficiency of
development and manufacturing activities, while ensuring the safety and
effectiveness of the combination products produced.
II. Proposed List of Mechanisms for Complying With Sec. 4.4 CGMP
Requirements for Combination Products
A. Introduction
The following is a proposed list of mechanisms for demonstrating
compliance with relevant combination product CGMP requirements, as
described below. Where applicable, reference is made to sections of the
``Guidance for Industry and FDA Staff: Current Good Manufacturing
Practice Requirements for Combination Products'' for additional
information (Ref. 1). FDA will continue to evaluate this list in light
of Agency experience and stakeholder input. Manufacturers are welcome
to propose other approaches not described, and FDA continues to
encourage dialogue with the Agency on various means of demonstrating
CGMP compliance for combination products.
For each mechanism described below, CP manufacturers should
consider what documentation would be sufficient to support that the
mechanism, including the specific approach for implementing it, assures
appropriate control of the manufacture of the combination product to
ensure safety and effectiveness of the product. Appropriate evidence
and an explanation of the rationale to support the approach should be
accessible at the manufacturing facility for review during facility
inspections. For additional discussion on how to interact with FDA
regarding the mechanisms described below, see section III.
B. Mechanisms for Complying With Drug CGMP Requirements (Part 211)
Specified in Sec. 4.4 2
---------------------------------------------------------------------------
\2\ Several drug CGMP mechanisms included in this proposed list
depend upon use of a more broadly defined batch. FDA notes that
approaches that depend upon broadly defined batches may increase the
number of distributed products implicated when corrective actions
are necessary to address postmarket issues.
---------------------------------------------------------------------------
FDA interprets the mechanisms identified in the sections below as a
means to demonstrate compliance with the specified part 211
requirements identified in Sec. 4.4:
1. Section 211.165 Testing and Release for Distribution
Use of product samples that are not finished combination products
(but that are representative of the finished combination product with
respect to the characteristics and attributes being tested) when
performing testing required by Sec. 211.165 to determine whether the
drug constituent part meets final specifications. To meet the
requirements of Sec. 211.165, the CP manufacturer would need to
establish, including where appropriate through bridging studies and
other quantitative means, that any differences in the manufacturing
process for the representative samples as compared to the finished
combination product do not affect the drug constituent part. For
example, as part of product release testing, drug-eluting lead
manufacturers could perform release testing for identity, potency, or
other quality attributes on a representative lead tip assembly that
contains the drug constituent part, but does not contain the full
electronic and mechanical assembly, so long as they can establish that
the differences in the manufacturing process do not impact the drug
constituent part and the sample is representative of the finished
combination product with respect to the quality attributes being
tested.
(See also Section IV.B.5 of Reference 1 for additional information
on testing and release for combination products.)
2. Section 211.166 Stability Testing
Use of bracketing and matrixing approaches to stability studies for
combination products. Principles for bracketing and matrixing
approaches to meet the requirements of Sec. 211.166 have already been
addressed by the Agency with regard to drug products (Ref. 2), and such
principles can also be applied to combination products. For example,
when assessing stability for a prefilled syringe that is marketed in
various fill volumes, one of the approaches that a CP manufacturer
could utilize, if appropriate, is bracketing based on the smallest and
the largest fill volume of product configurations. In determining the
extremes for a bracketing approach and/or when justifying the use of a
matrix design for single-entity combination products, it is important
that the drug-device interactions and variations in the manufacturing
processes are considered. For co-packaged combination products, such
approaches can be applied to the drug constituent part of the product.
Leveraging stability data for an already marketed combination
product. Such mechanisms can be considered when the new combination
product is a modification of an already marketed product and the
modification does not impact the stability of the drug constituent
part. For example, when developing new lengths of a drug-coated
catheter product for which the catheter materials, drug coating,
manufacturing process, and packaging configurations are largely
unchanged from existing marketed sizes, the CP manufacturer would
generally be able to leverage existing stability data to establish
initial product shelf life or to support reduced stability data
requirements, so long as characteristics of the product that could
impact stability (materials, packaging configuration, etc.) remain the
same. However, if the device constituent part of a drug-coated catheter
includes a new material that is in contact with the drug coating, for
example, new stability studies would generally be needed under Sec.
211.166.
[[Page 27612]]
(See also Section IV.B.6 of Reference 1 for additional information
on stability requirements for combination products.)
3. Section 211.167 Special Testing Requirements
Defining ``batch'' based on the drug constituent part rather than
the finished combination product for purposes of special testing
requirements for pyrogens and endotoxins. For example, a manufacturer
of a combination product that has a sub-assembly coated with a drug,
which is then incorporated into several ``batches'' or ``lots'' of the
overall combination product, may be able to define a batch for purposes
of pyrogen and endotoxin testing as a batch of that sub-assembly for
purposes of meeting the requirements of Sec. 211.167. As with the
other mechanisms described in this list, this mechanism would only
potentially be available if there would be no impact on the drug
constituent part from subsequent manufacturing processes, including
when the constituent parts are combined to produce the final
combination product. CP manufacturers should consider whether such
risks may be introduced later in the production process (after the
batch has been defined). This approach will most frequently apply for
co-packaged combination products or single-entity combination products
for which only a component or sub-assembly of the overall product is in
contact with the drug constituent part.
(See also Section IV.B.7 of Reference 1 for additional information
on special testing requirements for combination products.)
4. Section 211.170 Reserve Samples
Keeping reserve samples that are representative of the finished
combination product. CP manufacturers may use validated surrogates as
representative samples to meet the requirements of Sec. 211.170,
provided the surrogate is appropriate, both in terms of the
manufacturing process and the characteristics of the container closure.
For example, maintaining only a sub-assembly of a coated single-entity
combination product or only the drug constituent part of a co-packaged
combination product as a reserve sample would generally be permissible
under the regulation when: (1) All manufacturing process steps after
the coating step or the fill for the drug constituent part are shown
not to affect the drug constituent part, (2) the immediate container
closure has essentially the same characteristics as that for the drug
constituent part as packaged in the combination product for
distribution, and (3) the representative samples are suitable for all
required testing of the drug constituent part for which the reserve
samples are being kept.
Using samples from representative lots of a larger batch for
retention of reserve samples. To meet the requirements of Sec.
211.170, CP manufacturers may be able to use bracketing and matrixing
approaches to retain reserve samples from certain lots to adequately
represent the broadly defined batch of the combination product. For
example, CP manufacturers might be able to retain reserve samples of
appropriately varied sizes of a drug-coated combination product from
within a broadly defined batch that includes multiple lots of different
sizes.
(See also Section IV.B.8 of Reference 1 for additional information
on reserve sample requirements for combination products.)
C. Mechanisms for Complying With Device Quality System Requirements
(Part 820) Specified in Sec. 4.4
FDA interprets the mechanisms identified in the sections below as a
means to demonstrate compliance with the specified part 820
requirements identified in Sec. 4.4:
1. Section 820.30 Design Controls
Using existing pharmaceutical development practices and
documentation that align with the design control principles and
requirements of Sec. 820.30. Robust pharmaceutical development
practices would address many design control requirements to assure
compliance with Sec. 820.30, where applicable. CP manufacturers need
to demonstrate how development processes and terminology align with
design control principles and requirements in Sec. 820.30, when
required, including, where necessary, developing additional design
control elements. When evaluating the adequacy of existing
pharmaceutical development processes, particular attention should be
given to postmarket management of design changes to the combination
product and the alignment of change control practices with the
principles and requirements of Sec. 820.30, as applicable.
2. Exemption of Combination Products From Device QS Regulation
Exemption of the combination product from all or certain provisions
of the device QS regulation (part 820) if the device constituent part
of the combination product is itself exempt from such requirements and
use of the device constituent part falls within the scope of the
relevant exemption, including with respect to the device constituent
part's intended use. Some devices are exempt from all or certain
provisions of the device QS regulation (see, for example, liquid
medication dispensers such as cups and droppers that fall within the
scope of Sec. 880.6430 (21 CFR 880.6430), provided the use of the
device is not a new intended use or does not otherwise raise different
safety and effectiveness questions (see, for example, limitations to
the exemption under 21 CFR 880.9). Consistent with this, for the
combination product to be exempt from the associated provisions of the
device QS regulation, we interpret this exemption to mean that the use
of the device in the combination product must not be a new intended use
or otherwise raise different safety and effectiveness questions for the
device. This circumstance will most frequently apply to co-packaged
combination products. For example, an oral dosing syringe (a liquid
medication dispenser under Sec. 880.6430) that is co-packaged with a
drug may be exempt from certain provisions of the device QS regulation
(and hence the combination product may also be exempt from such
provisions); however, incorporation of such a dispenser into a primary
container closure system or co-packaging of such a dispenser with an
emergency-use product, for example, may constitute a new intended use
for the dispenser or raise different safety and effectiveness questions
for the dispenser, such that the relevant exemption would not apply.
(See also Section III.C.3 of Reference 1 for additional information
on the exemption from provisions of the device QS regulation for
combination products.)
III. Interacting With FDA on Mechanisms for Complying With CGMP for
Combination Products
1. Process for Interacting With FDA
In some cases, CP manufacturers may interact with FDA to gain
approval or otherwise notify FDA of a manufacturing change. In other
cases, although a submission or notification is not required, CP
manufacturers may want to discuss potential use of CGMP mechanisms with
FDA. CP manufacturers are encouraged to interact early with FDA on
contemplated CGMP mechanisms.
Pre-Submissions and Meeting Requests. CP manufacturers who
want to obtain FDA feedback prior to submitting a premarket application
or a postmarket supplement or who otherwise want to obtain feedback on
[[Page 27613]]
their approach may interact with FDA via the existing established
process applicable to the lead Center \3\ for the combination product.
For combination products reviewed under a new drug application (NDA) or
a biologics license application (BLA), such interactions will generally
be through Type C meetings (Ref. 3).\4\ For combination products
reviewed under an abbreviated new drug application (ANDA), these
interactions will generally be through pre-ANDA meetings (Ref. 4).\5\
For combination products reviewed under a device premarket submission
(e.g., a premarket approval application (PMA), de novo classification,
or premarket notification (510(k)), these interactions will generally
be via the pre-submission process (Ref. 5).
---------------------------------------------------------------------------
\3\ A combination product is assigned to an Agency center
(Center for Biologics Evaluation and Research, Center for Drug
Evaluation and Research, or Center for Devices and Radiological
Health) that will have primary jurisdiction (i.e., the ``lead
Center'') for that combination product's review and regulation.
Assignment of a combination product to a lead Center is based on a
determination of which constituent part provides the primary mode of
action of the combination product (21 U.S.C. 353(g)).
\4\ When final, this guidance will represent the FDA's current
thinking on this topic.
\5\ When final, this guidance will represent the FDA's current
thinking on this topic.
---------------------------------------------------------------------------
Regardless of the type of submission, such interactions should be
focused on a general discussion of the mechanism and CGMP approach the
CP manufacturer wishes to pursue and associated justification to
support the approach. Only representative data is typically appropriate
in these interactions; complete data should be included in the
subsequent premarket submission or postmarket supplement, if required,
and/or be maintained at the manufacturing facility, as appropriate.\6\
---------------------------------------------------------------------------
\6\ Note that when discussing a mechanism for complying with
CGMP requirements for which the CP manufacturer is leveraging
information in master file(s), the master file holder must submit a
letter of authorization to permit FDA to review such information
(see 21 CFR 314.420(d) and 21 CFR 814.20(c)). The specific
information within the master file that is being leveraged should be
clearly identified to FDA.
---------------------------------------------------------------------------
Premarket Review. CP manufacturers should include in their
original submission for NDAs, BLAs, ANDAs, and PMAs information on any
mechanisms for complying with CGMP requirements. For PMAs, this
information should be included in the manufacturing section of the PMA.
For information regarding where to place information in NDAs, BLAs, or
ANDAs, refer to ``eCTD Technical Conformance Guide'' (Ref. 6).
Postmarket Supplements or Notifications to FDA. Postmarket
changes to implement a combination product CGMP mechanism for NDAs,
ANDAs, BLAs, and PMAs, may require submission of a supplement or
notification to FDA.\7\ CP manufacturers should consult related
guidances relevant to the type of constituent part of the combination
product (Refs. 7 to 9).\8\ If a CP manufacturer has questions on the
appropriate submission type or the need for a submission, they can
contact the lead Center for assistance.
---------------------------------------------------------------------------
\7\ Requirements for postmarket supplements are contained, for
example, in 21 CFR 314.70 (NDAs), 21 CFR 601.12 (BLAs), and 21 CFR
814.39 (PMAs). Any questions on whether FDA review is required for a
postmarket CGMP mechanism should be directed to the lead Center.
\8\ With reference to Ref. 8, when final, this guidance will
represent the FDA's current thinking on this topic.
---------------------------------------------------------------------------
2. Content Suggestions
When submitting information on a CGMP mechanism, along with any
submission requirements applicable to the submission type, the
following content should be included:
Applicable CGMP regulation. Identify the CGMP regulation
applicable to the described mechanism. For example, if a submission
includes a mechanism related to stability testing, indicate that Sec.
211.166 is the applicable CGMP requirement.
Applicable Products. If the mechanism is to be applied to
multiple products and/or product configurations, list all related
sizes, strengths, etc., as well as all related application numbers.
Related Interactions with FDA. If the CP manufacturer has
had previous interactions with FDA relevant to the proposed mechanism,
either for the product addressed in the submission or for related
products, the CP manufacturer should provide reference to those
interactions. Where applicable, the CP manufacturer may cross-reference
previously submitted information.
Justification and Scientific Data. Include a rationale to
support that the proposed mechanism assures adequate manufacturing
control to ensure product safety and effectiveness. When describing a
CGMP mechanism in a premarket or postmarket submission, the description
should be accompanied by data necessary to support the approach. When
proposing a change from a CGMP approach that was reviewed previously by
FDA, such justification should include analysis of how the proposed
approach compares to the previously reviewed approach as an effective
manufacturing control, including representative data, as appropriate,
to substantiate the analysis.
3. FDA Engagement
CP manufacturers are encouraged to discuss combination product CGMP
mechanisms with FDA. Any questions on how to engage FDA in such
discussions should be directed to the lead Center for the product or
the Office of Combination Products, as needed.
4. FDA Review
FDA may review information from a CP manufacturer related to a
mechanism for complying with CGMP requirements for combination products
in premarket applications, postmarket supplements or notifications,
pre-submissions and meetings, and during facility inspections. FDA may
determine that the data and rationale presented by a CP manufacturer
for a particular mechanism are insufficient to demonstrate that the
mechanism, as proposed or implemented, meets the applicable CGMP
requirement. FDA generally will notify the CP manufacturer and/or
applicant in writing of any such determination.
IV. Other Issues for Consideration
We have developed this proposed list of mechanisms based on
information submitted to FDA by CP manufacturers as well as FDA
experience with manufacturing processes and CGMP compliance approaches
that have been shown through appropriate data and rationales to support
the manufacture of safe and effective products. FDA requests comment
from stakeholders who believe there are additional types of combination
products and/or manufacturing processes where different approaches may
be appropriate. When providing such feedback, the suggested approach
should be:
Applicable to a type or range of combination products
(e.g., not just a single CP manufacturer's product). Commenters should
indicate to which types of combination products or manufacturing
processes they believe the suggested approach should apply.
Supported by adequate data and rationales to demonstrate
that such an approach would continue to support manufacturing of safe
and effective combination products. Commenters should summarize the
data and rationale that support the suggested approach.
Any confidential information submitted to FDA via the docket should be
appropriately identified (see Instructions above, in ADDRESSES).
