[Docket No. FDA-2023-N-3275]
Effective Date of Requirement for Premarket Approval Applications
for Certain Solid Wound Dressings; Wound Dressings Formulated as a Gel,
Cream, or Ointment; and Liquid Wound Washes Containing Medically
Important Antimicrobials
AGENCY: Food and Drug Administration, HHS.
ACTION: Proposed amendment; proposed order.
-----------------------------------------------------------------------
SUMMARY: The Food and Drug Administration (FDA, Agency, or we) is
proposing to require the filing of a premarket approval application
(PMA) for certain solid wound dressings; wound dressings formulated as
a gel, cream, or ointment; and liquid wound washes containing
antimicrobials with a high level of antimicrobial resistance (AMR)
concern (i.e., medically important antimicrobials) acting as either
protectants or preservatives, which are unclassified, preamendments
devices. FDA is summarizing its proposed findings regarding the degree
or risk of illness or injury designed to be eliminated or reduced by
requiring the devices to meet the PMA requirements of the Federal Food,
Drug, and Cosmetic Act (FD&C Act) and the benefits to the public from
the use of the devices.
DATES: Either electronic or written comments on the proposed order must
be submitted by February 28, 2024. FDA intends that, if a final order
based on this proposed order is issued, anyone who wishes to market
solid wound dressings, wound dressings formulated as a gel, cream, or
ointment, and liquid wound washes containing medically important
antimicrobials acting as either protectants or preservatives must
submit a PMA prior to the last day of the 30th calendar month beginning
after the month in which the classification of the device in class III
became effective. See section III for the effective date of any final
order that may publish based on this proposed order. See section VI of
this document for more information about submitting a PMA.

SUPPLEMENTARY INFORMATION:
I. Background--Regulatory Authorities
The FD&C Act, as amended, establishes a comprehensive system for
the regulation of medical devices intended for human use. Section 513
of the FD&C Act (21 U.S.C. 360c) established three classes of devices,
reflecting the regulatory controls needed to provide reasonable
assurance of their safety and effectiveness. The three classes of
devices are class I (general controls), class II (special controls and
general controls), and class III (premarket approval and general
controls). Under section 513(d)(1) of the FD&C Act, devices that were
in commercial distribution before the enactment on May 28, 1976 of the
1976 amendments (Medical Device Amendments of 1976, Pub. L. 94-295)
(generally referred to as ``preamendments devices'') are classified
after FDA has (1) received a recommendation from a device
classification panel (an FDA advisory committee); (2) published the
panel's recommendation for comment, along with a proposed regulation
classifying the device; and (3) published a final regulation
classifying the device. FDA has classified most preamendments devices
under these procedures.
A person may market a preamendments device that has been classified
into class III through premarket notification procedures, without
submission of a PMA until FDA issues an administrative order under
section 515(b) of the FD&C Act (21 U.S.C. 360e(b)) requiring premarket
approval.
Section 515(f) of the FD&C Act provides an alternative pathway for
meeting the premarket approval requirement. Under section 515(f),
manufacturers may meet the premarket approval requirement if they file
a notice of completion of a product development protocol (PDP) approved
under section 515(f)(4) of the FD&C Act and FDA declares the PDP
completed under section 515(f)(6)(B) of the FD&C Act. Accordingly, the
manufacturer of a preamendments class III device may comply with a call
for PMAs by filing a PMA or a notice of completion of a PDP. In
practice, however, the option of filing a notice of completion of a PDP
has rarely been used. For simplicity, although the PDP option remains
available to manufacturers in response to a final order under section
515(b) of the FD&C Act, this document will refer only to the
requirement for filing and obtaining approval of a PMA.
Section 515(b)(1) of the FD&C Act sets forth the process for
issuing a final order. Specifically, prior to the issuance of a final
order requiring premarket approval for a preamendments class III
device, the following must occur: (1) publication of a proposed order
in the Federal Register; (2) a meeting of a device classification panel
described in section 513(b) of the FD&C Act; and (3) consideration of
comments from all affected stakeholders, including patients, payors,
and providers.
Section 515(b)(2) of the FD&C Act provides that a proposed order to
require premarket approval shall contain: (1) the proposed order; (2)
proposed findings with respect to the degree of risk of illness or
injury designed to be eliminated or reduced by requiring the device to
have an approved PMA, and the benefit to the public from the use of the
device; (3) an opportunity for the submission of comments on the
proposed order and the proposed findings; and (4) an opportunity to
request a change in the classification of the device based on new
information relevant to the classification of the device.
Section 515(b)(3) of the FD&C Act provides that FDA shall, after
the close of the comment period on the proposed order,\1\ consideration
of any comments received, and a meeting of a device classification
panel described in section 513(b) of the FD&C Act, issue a final order
to require premarket approval or publish a document terminating the
proceeding together with the reasons for such termination. If FDA
terminates the proceeding, FDA is required to initiate reclassification
of the device under section 513(e) of the FD&C Act, unless the reason
for termination is that the device is a banned device under section 516
of the FD&C Act (21 U.S.C. 360f).
---------------------------------------------------------------------------
\1\ In December 2019, FDA began adding the term ``Proposed
amendment'' to the ``ACTION'' caption for these documents to
indicate that they ``propose to amend'' the Code of Federal
Regulations. This editorial change was made in accordance with the
Office of the Federal Register's interpretations of the Federal
Register Act (44 U.S.C. chapter 15), its implementing regulations (1
CFR 5.9 and parts 21 and 22), and the Document Drafting Handbook.
---------------------------------------------------------------------------
A preamendments class III device may be commercially distributed
without a PMA until 90 days after FDA issues a final order requiring
premarket approval for the device, or 30 months after the
classification of the device in class III under section 513 of the FD&C
Act becomes effective, whichever is later (section 501(f)(2)(B) of the
FD&C Act (21 U.S.C. 351(f)(2)(B)). Elsewhere in this issue of the
Federal Register, FDA is proposing to classify solid wound dressings;
wound dressings formulated as a gel, cream, or ointment; and liquid
wound washes containing antimicrobials with a high level of AMR (i.e.,
the ability of a microorganism to resist the effects of an
antimicrobial) concern to class III. Therefore, if the proposed
classification regulation and the order to require PMAs are finalized
at the same time, a PMA for these wound dressings must be filed within
the 30-month period because that will be the later of the two time
periods. If a PMA is not timely filed for such devices, then the device
would be deemed adulterated under section 501(f) of the FD&C Act.
Also, a preamendments device subject to the order process under
section 515(b) of the FD&C Act is not required to have an approved
investigational device exemption (IDE) (see part 812 (21 CFR part 812))
contemporaneous with its interstate distribution until the date
identified by FDA in the final order requiring the filing of a PMA for
the device. At that time, an IDE is required only if a PMA has not been
filed. If the manufacturer, importer, or other sponsor of the device
submits an IDE application and FDA approves it, the device may be
distributed for investigational use. If a PMA is not filed by the later
of the two dates, and the device is not distributed for investigational
use under an IDE, the device is deemed adulterated within the meaning
of section 501(f)(1)(A) of the FD&C Act and subject to enforcement
action.
II. Regulatory History of the Devices
After the enactment of the Medical Device Amendments of 1976, FDA
undertook an effort to identify and classify all preamendments devices,
in accordance with section 513(d) of the FD&C Act. Consistent with the
FD&C Act, FDA has held multiple General and Plastic Surgery Devices
Panel meetings regarding the classification of wound dressings: on
November 27, 1998 (Ref. 1); August 25 and 26, 2005 (Ref. 2); and
September 20 and 21, 2016 (the 2016 Panel) (Ref. 3). However, only the
2016 Panel meeting provided the class III recommendations. Certain
solid wound dressings; wound dressings formulated as a gel, cream, or
ointment; and liquid wound washes containing medically important
antimicrobials (i.e., antimicrobial drugs that are important for
therapeutic use in humans and associated with a high level of AMR
concern) pose different risks than other
[[Page 83804]]
wound dressings. Elsewhere in this issue of the Federal Register, FDA
is proposing to classify certain unclassified, preamendments solid
wound dressings; wound dressings formulated as a gel, cream, or
ointment; and liquid wound washes containing medically important
antimicrobials into class III. A PMA, in addition to general controls,
will provide reasonable assurance of the safety and effectiveness of
these devices.
The proposed rule would also establish the identification,
classification, and regulatory controls for certain solid wound
dressings; wound dressings formulated as a gel, cream, or ointment; and
liquid wound washes that contain antimicrobials acting as either
protectants or preservatives with a medium or low level of AMR concern
and/or other chemicals. These devices have been subject to premarket
review through a 510(k) submission and have been cleared for marketing
if FDA considers the device to be substantially equivalent to a legally
marketed predicate in accordance with section 513(i) of the FD&C Act.
To date, FDA has cleared more than 500 of these devices and has cleared
only one of the device types that we believe will be subject to the PMA
requirements.
On September 20 and 21, 2016, the 2016 Panel met for the purposes
of obtaining recommendations about the classification of products,
including (1) solid wound dressings; (2) wound dressings formulated as
a gel, cream, or ointment; and (3) liquid wound washes (Ref. 3). FDA
held the 2016 Panel to obtain input on the risks to health and benefits
of wound dressings and liquid wound washes that contain antimicrobials
and/or other chemicals, as well as the clinical relevance of certain
indications. The 2016 Panel was asked to recommend to FDA whether such
wound dressings and liquid wound washes that contain antimicrobials
and/or other chemicals should be classified into class III (subject to
premarket approval), class II (subject to general and special
controls), or class I (subject only to general controls). The 2016
Panel was also asked to discuss the types of evidence (including
clinical evidence) that would be helpful to support certain
indications, as well as appropriate controls necessary to mitigate the
risks to health and assure the safety and effectiveness of these types
of wound dressings and liquid wound washes.
For solid wound dressings containing antimicrobials and/or other
chemicals, the 2016 Panel reviewed the list of risks to health and
potential mitigation measures provided by FDA and agreed that the list
was acceptable. In general, a majority of the 2016 Panel recommended
that solid wound dressings should be classified into class II, subject
to special controls, with the exception of certain solid wound
dressings containing antimicrobials, such as antibiotics (with similar
consideration to antimicrobial agents that may select for resistance in
indirect ways). Some of the 2016 Panel believed all wound dressings and
liquid wound washes containing antimicrobials and/or other chemicals
should be classified as class III because of the absence of high-
quality evidence of benefit; others recommended class III be considered
for any product containing an antibiotic or an antimicrobial that may
indirectly contribute to antibiotic resistance.
For wound dressings containing antimicrobials and/or other
chemicals formulated as a gel, cream, or ointment, the 2016 Panel
reviewed the list of risks to health and potential mitigation measures
provided by FDA and agreed that the list was acceptable. In general, a
majority of the 2016 Panel recommended that wound dressings formulated
as a gel, cream, or ointment should be classified into class II,
subject to special controls, with the exception of certain wound
dressings formulated as a gel, cream, or ointment containing
antimicrobials, such as antibiotics (with similar consideration to
agents that may select for resistance in indirect ways), for which some
members of the 2016 Panel recommended class III.
For liquid wound washes containing antimicrobials and/or other
chemicals, the 2016 Panel reviewed the list of risks to health and
potential mitigation measures provided by FDA and agreed that the list
was acceptable. In general, a majority of the 2016 Panel recommended
that liquid wound washes should be classified into class I or class II,
subject to special controls, depending on the toxicity of the product,
with the exception of certain liquid wound washes containing
antimicrobials, such as antibiotics (with similar consideration to
agents that may select for resistance in indirect ways), for which some
members of the 2016 Panel recommended class III.
The 2016 Panel recommended that wound dressings and liquid wound
washes with medically important antimicrobials \2\ (Ref. 4) be
classified into class III because there was a lack of available
evidence to determine that general and special controls are sufficient
to provide reasonable assurance of safety and effectiveness, and these
devices present a potential unreasonable risk of illness or injury. FDA
agrees with the 2016 Panel's recommendation. It is also FDA's position
that there is a lack of available evidence to determine that general
and special controls are sufficient to provide reasonable assurance of
the devices' safety and effectiveness and that the devices present a
potential unreasonable risk of illness or injury. FDA further agrees
with the 2016 Panel's recommendation that wound dressings and liquid
wound washes with medically important antimicrobials and/or other
chemicals be classified into class III subject to PMA.
---------------------------------------------------------------------------
\2\ Table 1 of the World Health Organization's (WHO) 2018
publication ``Critically important antimicrobials for human
medicine: 6th revision'' (https://www.who.int/publications/i/item/9789241515528) has a list of all classes of medically important
antimicrobials. For the purposes of this proposed order, an
antimicrobial is considered medically important if, and only if, it
falls within any of these classes regardless of the level of
importance specified by the WHO (i.e., critically important, highly
important, or important).
---------------------------------------------------------------------------
III. Dates New Requirements Apply
If FDA finalizes the proposed classification of certain solid wound
dressings; wound dressings formulated as a gel, cream, or ointment; and
liquid wound washes containing medically important antimicrobials
acting as either protectants or preservatives, these devices will be
classified into class III. In accordance with sections 501(f)(2)(B) and
515(b) of the FD&C Act, FDA is proposing to require that a PMA be filed
with the Agency for certain solid wound dressings; wound dressings
formulated as a gel, cream, or ointment; and liquid wound washes
containing medically important antimicrobials acting as either
protectants or preservatives by the last day of the 30th calendar month
beginning after the month in which the classification of the device in
class III became effective.
An applicant whose product was legally in commercial distribution
before May 28, 1976, or whose product has been found to be
substantially equivalent to such a product, will be permitted to
continue marketing such class III product during FDA's review of the
PMA, provided that a PMA is timely filed. FDA intends to review any PMA
for the device within 180 days. FDA cautions that under section
515(d)(1)(B)(i) of the FD&C Act, the Agency may not enter into an
agreement to extend the review period for a PMA beyond 180 days, unless
the Agency finds that ``. . . the continued availability of the device
is necessary for the public health.''
[[Page 83805]]
Moreover, manufacturers must cease distribution of devices upon
receiving a not approvable or denial decision rendered on a PMA. In
such circumstances, to resume distribution, these manufacturers must
receive PMA approval for their devices. However, the product may be
distributed for investigational use only if the requirements of the
investigational device exemptions regulations in part 812 are met. The
requirements for investigational use of significant risk devices
include submitting an IDE application to FDA for review and approval.
An approved IDE is required to be in effect before an investigation of
the device may be initiated or continued under 21 CFR 812.30. FDA,
therefore, recommends that IDE applications be submitted to FDA at
least 30 days before the date a PMA is required to be filed to avoid
interrupting investigations.
For currently marketed wound dressings and liquid wound washes that
are proposed to be classified into class III, FDA is proposing that it
does not intend to enforce compliance with the 30-month deadline by
which PMAs must be submitted, when a notice of intent to file a PMA is
submitted within 90 days of the effective date of the order, if
finalized. In circumstances when a notice of intent to file is
submitted, FDA is proposing that it does not intend to enforce
compliance with the 30-month deadline by which PMAs must be submitted
when a PMA is submitted within 90 days after the 30-month deadline.
However, as discussed above, even if a notice of intent and PMA are
submitted by these dates, manufacturers must cease distribution of
devices upon receiving a not approvable or denial decision rendered on
a PMA.
IV. Devices Subject to This Proposal
A solid wound dressing containing antimicrobials and/or other
chemicals is used to cover and protect a wound, to absorb exudate, and
to maintain appropriate moisture balance within the wound. Medically
important antimicrobials that are incorporated in the solid wound
dressing are used for protectant purposes only to reduce microbial
growth within the solid wound dressing while in use or to provide an
antimicrobial barrier to microbial penetration through the solid wound
dressing.
A wound dressing formulated as a gel, cream, or ointment containing
antimicrobials and/or other chemicals is used to maintain appropriate
moisture balance within the wound. Medically important antimicrobials
that are incorporated in a wound dressing formulated as a gel, cream,
or ointment are used for preservative purposes only to maintain shelf
life for a non-sterile wound dressing or a multiple-use wound dressing
for single patient use only.
A liquid wound wash is a water-based solution used to mechanically
irrigate and physically remove debris from external wounds. It is also
used to moisten solid wound dressings to maintain appropriate moisture
balance within the dressing. Medically important antimicrobials that
are incorporated in a liquid wound wash are used for preservative
purposes only to maintain shelf life for a non-sterile liquid wound
wash or a multiple-use wound wash for single patient use only.
FDA currently regulates these unclassified devices as devices
requiring a 510(k) submission under product codes FRO, GER, MGP, MGQ,
and EFQ.
Elsewhere in this issue of the Federal Register, FDA is proposing
to classify certain solid wound dressings; wound dressings formulated
as a gel, cream, or ointment; and liquid wound washes containing
medically important antimicrobials acting as either protectants or
preservatives in class III and identifies these devices as follows:
solid wound dressings containing antimicrobials and/or other chemicals;
wound dressings formulated as a gel, cream, or ointments containing
antimicrobials and/or other chemicals; and liquid wound washes.
In accordance with section 515(b)(2)(D) of the FD&C Act, interested
persons are being offered the opportunity to comment or request a
change on the Agency's proposed classification of certain solid wound
dressings; wound dressings formulated as a gel, cream, or ointment; and
liquid wound washes containing medically important antimicrobials
acting as either protectants or preservatives based on new information
published elsewhere in this Federal Register.
V. Proposed Findings With Respect to Risks and Benefits for Solid Wound
Dressings; Wound Dressings Formulated as a Gel, Cream, or Ointment; and
Liquid Wound Washes Containing Medically Important Antimicrobials
As required by section 515(b) of the FD&C Act, FDA is publishing
its proposed findings regarding: (1) the degree of risk of illness or
injury designed to be eliminated or reduced by requiring that these
devices have an approved PMA and (2) the benefits to the public from
the use of the devices. These findings are based on the reports and
recommendations of the 2016 Panel, and any additional information that
FDA has obtained. Additional information regarding the risks can be
found below, as well as in the proposed rule published elsewhere in
this issue of the Federal Register, proposing to classify these devices
into class III.
Based on this information, FDA has identified the following risks
to health to the different categories of wound dressings and liquid
wound washes that are within the scope of this proposed rule and
classification action:
Solid Wound Dressings:
[cir] Adverse tissue reaction, immunological reaction, transmission
of pathogens and parasites, toxicity, delayed wound healing,
incompatibilities with other therapies, contribution to the spread of
AMR, infection, microbial growth within the product, product
degradation during stated shelf storage, loss of barrier function,
retention of dressing material in wound, and negatively impacting the
skin microbiota in the peri-wound area resulting in impaired wound
healing.
Wound Dressings Formulated as a Gel, Cream, or Ointment:
[cir] Adverse tissue reaction, immunological reaction, transmission
of pathogens and parasites, toxicity, delayed wound healing,
incompatibilities with other therapies, contribution to the spread of
AMR, infection, microbial growth within the product, product
degradation during stated shelf storage, and negatively impacting the
skin microbiota in the peri-wound area resulting in impaired wound
healing.
Liquid Wound Washes:
[cir] Adverse tissue reaction, immunological reaction, transmission
of pathogens and parasites, toxicity, delayed wound healing,
incompatibilities with other therapies, contribution to the spread of
AMR, infection, microbial growth within the product, product
degradation during stated shelf storage, inability to remove wound
debris and foreign materials, and negatively impacting the skin
microbiota in the peri-wound area resulting in impaired wound healing.
Below is a brief description of each of the identified risks to
health:
Adverse tissue reaction: Erythema, irritation,
inflammation of the wound or host tissue, immune response, and
hemolysis can occur as a result of an unwanted tissue response
associated with the materials or leachables/extractables in wound
dressings and liquid wound washes.
Immunological reaction: This can result from a device
derived from a new animal source or protein denaturation/
[[Page 83806]]
modification due to the manufacturing conditions.
Transmission of pathogens and parasites (e.g., bacteria,
mycoplasma, fungi, viruses, and other transmissible spongiform
encephalopathy agents): This can result from contaminated animal
sources, feed, inadequate processing, and viral inactivation of the
animal-derived materials.
Toxicity: Local and/or systemic toxicity, tissue necrosis,
reduced tissue viability, and genotoxicity can occur due to toxic
antimicrobials or other chemicals in the wound dressings or liquid
wound washes, which can result in adverse tissue effects, leading to
toxicity. This also includes allergic reaction and sensitization, as
individuals with known sensitivity to the materials in the wound
dressings and liquid wound washes may experience allergic reactions,
which may be severe depending on the degree of sensitivity.
Delayed wound healing: Cytotoxicity resulting in dead or
necrotic tissue can delay healing.
Incompatibilities with other therapies: An undesirable
(e.g., antagonistic) reaction could occur between the materials
contained in/on the wound dressings or liquid wound washes and other
therapies applied to the wound.
Contribution to the spread of AMR: Use of antimicrobials
in wound dressings and liquid wound washes can inadvertently select for
and cultivate antimicrobial resistant organisms in patients and further
limit a clinician's therapeutic options to treat infections.
Infection: Unsafe methods of manufacturing processes, such
as inadequate aseptic processing, inadequate packaging and/or product
storage, can result in contaminated product that may be a source of
infection. This risk includes bacterial and fungal infections and
superinfections, which may result from the use of an antimicrobial-
containing wound dressing or liquid wound wash that introduces
contaminating microorganisms to the wound or disrupts the natural
balance of skin flora around the wound.
Microbial growth within the product: This can occur from
inadequate sterilization, preservative effectiveness failure, unsafe
methods of manufacturing processes, inadequate packaging and/or product
storage. This can lead to a change in product composition or
characteristics (e.g., loss of tensile strength, change in pH) and may
also result in infection or adverse tissue reaction.
Product degradation during stated shelf storage:
Inadequate packaging and/or inappropriate storage of wound dressings or
liquid wound washes can result in product degradation during storage.
Product degradation can also change the composition or characteristics
of the product over time and lead to patient harm.
Retention of dressing material in wound: This risk is
generally applicable to solid wound dressings, which can occur due to a
loss in solid dressing integrity or unintended degradation of solid
wound dressings. It may also occur due to the healthcare provider
inadvertently leaving material in the wound. This can lead to adverse
tissue reaction, delay in wound healing, or infection.
Inability to remove wound debris and foreign materials:
Ineffective washing of the wound can occur. Debris and foreign material
remaining in the wound can delay healing or lead to infection. This
risk is applicable to the liquid wound washes containing antimicrobials
and/or other chemicals.
Loss of barrier function: This risk is applicable to solid
wound dressings indicated as barriers to microbial penetration through
the wound dressing (either via mechanical or antimicrobial properties).
Loss of this barrier function can introduce microbial contamination
from the environment into the wound and can lead to delay in wound
healing or infection.
Impact to skin microbiota in the peri-wound area: This
risk is applicable to each category of antimicrobial-containing wound
dressings. Inadvertent leaching of antimicrobials away from the
dressing may negatively impact the skin microbiota in the peri-wound
area by reducing the presence of beneficial commensal microorganisms
that play a role in the wound healing cascade, resulting in impaired
wound healing.
A. Summary of Data
FDA conducted queries of the Manufacturer and User Facility Device
Experience database to identify adverse events related to use of solid
wound dressings; wound dressings formulated as a gel, cream, or
ointment; and liquid wound washes containing medically important
antimicrobials acting as either protectants or preservatives. The
queries resulted in the identification of 1,973 Medical Device Reports
(MDRs) on these devices as of July 21, 2022. The reports were received
by FDA from 1994 to July 21, 2022. The number of MDRs received between
1994 and 2004 were consistently low, at fewer than 20 per year. Between
2005 and 2016, the number of MDRs increased to an average of 111
reports per year with a peak in 2015, at 298 MDRs. MDRs received
between 2016 and 2022 averaged 148 17 MDRs per year.
Additionally, FDA conducted a comprehensive literature review to
identify and gather relevant published information regarding the safety
and effectiveness of solid wound dressings; wound dressings formulated
as a gel, cream, or ointment; and liquid wound washes containing
medically important antimicrobials acting as either protectants or
preservatives. Consequently, FDA concludes there is inadequate
information characterizing the safety and effectiveness of wound
dressings and liquid wound washes containing medically important
antimicrobials. The 510(k) clearances of these devices were based
solely on nonclinical information and determinations of substantial
equivalence to the preamendments device in accordance with section
513(i) of the FD&C Act, which, in light of the available information
regarding the risks with no information supporting the benefit of these
devices, is inadequate to support a reasonable assurance of safety and
effectiveness for these devices.
FDA also reviewed recalls reported under product code FRO from 2003
to July 2022.\3\ There are no recalls for solid wound dressings; wound
dressings formulated as a gel, cream, or ointment; or liquid wound
washes containing medically important antimicrobials acting as either
protectants or preservatives.
---------------------------------------------------------------------------
\3\ Only the product code FRO was queried for the recall
analysis as the majority of the products in scope for this proposed
order fall under FRO. The types of recalls reported under FRO are
expected to be representative of all products in scope for this
proposed order.
---------------------------------------------------------------------------
On September 20 and 21, 2016, FDA convened the General and Plastic
Surgery Device Panel described in section II (Ref. 3). The majority of
the 2016 Panel members noted that there is a lack of clinical data to
demonstrate a clear clinical benefit regarding the use of wound
dressings and liquid wound washes containing medically important
antimicrobials. Several of the 2016 Panel members noted that wound
dressings and liquid wound washes containing medically important
antimicrobials, such as antibiotics, present an unreasonable risk of
illness or injury to the patient (e.g., directly contributing to the
spread of antimicrobial resistance, further limiting clinician's
therapeutic options), especially given the lack of probable benefit.
Additionally, the 2016 Panel members discussed that special
[[Page 83807]]
controls, such as testing in an animal model, could not be used to
evaluate and/or mitigate the high level of AMR risk. As such, several
panelists concluded that these wound dressings and liquid wound washes
should be classified as class III and subject to increased regulatory
controls to mitigate the high level of AMR risk.
B. Benefits of the Device
The purported benefit of the use of wound dressings and liquid
wound washes containing medically important antimicrobials acting as
either protectants or preservatives include maintaining a moist
environment, providing an effective barrier to environmental
contaminants, reducing microbial growth within the dressing, and
extending the shelf life of non-sterile and/or multiple-use wound
dressings and liquid wound washes; however, FDA is not aware of
clinical evidence supporting the stated benefit of wound dressings and
liquid wound washes containing medically important antimicrobials. FDA
is proposing a PMA be filed to require that manufacturers demonstrate
that a reasonable assurance of safety and effectiveness exists for
solid wound dressings; wound dressings formulated as a gel, cream, or
ointment; and liquid wound washes containing medically important
antimicrobials acting as either protectants or preservatives.
C. Risks to Health
The unreasonable risk profile of solid wound dressings; wound
dressings formulated as a gel, cream, or ointment; and liquid wound
washes containing medically important antimicrobials acting as either
protectants or preservatives includes adverse tissue reaction,
immunological reaction, transmission of pathogens and parasites,
toxicity, delayed wound healing, incompatibility with other therapies,
contribution to the spread of AMR, infection, microbial growth within
the product during use, product degradation during stated shelf
storage, retention of dressing material in wound, loss of barrier
function, inability to remove wound debris and foreign materials, and
negatively impacting the skin microbiota in the peri-wound area
resulting in impaired wound healing.
FDA agrees with certain 2016 Panel members that wound dressings and
liquid wound washes containing medically important antimicrobials
present an unreasonable risk of illness or injury. FDA further agrees
that because insufficient information exists to determine that general
and special controls are sufficient to provide reasonable assurance of
the safety and effectiveness, wound dressings and liquid wound washes
containing medically important antimicrobials should be class III
subject to PMA.
VI. PMA Requirements
A PMA for solid wound dressings; wound dressings formulated as
gels, creams, and ointments; and liquid wound washes containing
medically important antimicrobials acting as either protectants or
preservatives must include the information required by section
515(c)(1) of the FD&C Act. Such a PMA should also include a detailed
discussion of the risks identified in section V, as well as a
discussion of the effectiveness of the product for which premarket
approval is sought. In addition, a PMA must include all data and
information on the following: (1) any risks known, or that should be
reasonably known, to the applicant that have not been identified in
this document; (2) the effectiveness of the device that is the subject
of the application; and (3) full reports of all preclinical and
clinical information from investigations on the safety and
effectiveness of the device for which premarket approval is sought.
A PMA must include valid scientific evidence to demonstrate
reasonable assurance of the safety and effectiveness of the solid wound
dressing; wound dressing formulated as gels, creams, and ointments; or
liquid wound wash containing medically important antimicrobials acting
as either protectants or preservatives for its intended use (see Sec.
860.7(c)(2) (21 CFR 860.7(c)(2))). FDA defines valid scientific
evidence in Sec. 860.7(c)(2).
To present reasonable assurance of safety and effectiveness of
solid wound dressings; wound dressings formulated as gels, creams, and
ointments; and liquid wound washes containing medically important
antimicrobials acting as either protectants or preservatives, FDA
tentatively concludes that manufacturers should submit performance
testing to support PMA approval. Existing published clinical literature
relevant to the product may also be leveraged as part of the PMA
submission. In addition, FDA strongly encourages manufacturers to meet
with the Agency early through the Q-Submission Program \4\ for any
assistance in preparation of their PMA.

VII. Analysis of Environmental Impact
We have determined under 21 CFR 25.34(b) 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.
VIII. Paperwork Reduction Act of 1995
While this proposed order contains no collection of information, it
does refer to previously approved FDA collections of information. The
previously approved collections of information are subject to review by
the Office of Management and Budget (OMB) under the Paperwork Reduction
Act of 1995 (PRA) (44 U.S.C. 3501-3521). The collections of information
in 21 CFR part 814, subparts A through E, have been approved under OMB
control number 0910-0231; and the collections of information in part
812 have been approved under OMB control number 0910-0078.
IX. Proposed Effective Date
FDA is proposing that any final order based on this proposal become
effective on the date of its publication in the Federal Register or at
a later date if stated in the final order.
X. Opportunity To Request a Change in Classification
Before requiring the filing of a PMA or notice of completion of a
PDP for a device, FDA is required by section 515(b)(2)(D) of the FD&C
Act to provide an opportunity for interested persons to request a
change in the classification of the device based on new information
relevant to the classification of the device. A request for a change in
the classification of solid wound dressings; wound dressings formulated
as gels, creams, and ointments; and liquid wound washes containing
medically important antimicrobials acting as either protectants or
preservatives, as described in this document, should be provided in
response to the proposed rule issued elsewhere in this issue of the
Federal Register and contain the information required by 21 CFR
860.123, including new information relevant to the classification of
the device.
