SUPPLEMENTARY INFORMATION:
I. Background—Regulatory Authorities
The Federal Food, Drug, and Cosmetic
Act (the FD&C Act), as amended by the
Medical Device Amendments of 1976
(the 1976 amendments) (Pub. L. 94–
295), the Safe Medical Devices Act of
1990 (SMDA) (Pub. L. 101–629), and the
Food and Drug Administration
Modernization Act of 1997 (FDAMA)
(Pub. L. 105–115), the Medical Device
User Fee and Modernization Act of 2002
(MDUFMA) (Pub. L. 107–250), the
Medical Devices Technical Corrections
Act (Pub. L. 108–214), and the Food and
Drug Administration Amendments Act
of 2007 (Pub. L. 110–85), among other
amendments, establish 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 categories
(classes) of devices, reflecting the
regulatory controls needed to provide
reasonable assurance of their safety and
effectiveness. The three categories of
devices are class I (general controls),
class II (special controls), and class III
(premarket approval).
Under section 513 of the FD&C Act,
devices that were in commercial
distribution before the enactment of the
1976 amendments, May 28, 1976
(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.
Devices that were not in commercial
distribution prior to May 28, 1976
(generally referred to as
postamendments devices) are
automatically classified by section
513(f) of the FD&C Act into class III
without any FDA rulemaking process.
Those devices remain in class III and
require premarket approval unless, and
until, the device is reclassified into class
I or II or FDA issues an order finding the
device to be substantially equivalent, in
accordance with section 513(i) of the
FD&C Act, to a predicate device that
does not require premarket approval.
The Agency determines whether new
VerDate Mar<15>2010
18:42 Aug 05, 2011
Jkt 223001
devices are substantially equivalent to
predicate devices by means of
premarket notification procedures in
section 510(k) of the FD&C Act (21
U.S.C. 360(k)) and 21 CFR part 807.
A preamendments device that has
been classified into class III may be
marketed by means of premarket
notification procedures (510(k) process)
without submission of a PMA) until
FDA issues a final regulation under
section 515(b) of the FD&C Act (21
U.S.C. 360e(b)) requiring premarket
approval. Section 515(b)(1) of the FD&C
Act establishes the requirement that a
preamendments device that FDA has
classified into class III is subject to
premarket approval. A preamendments
class III device may be commercially
distributed without an approved PMA
or a notice of completion of a PDP until
90 days after FDA issues a final rule
requiring premarket approval for the
device, or 30 months after final
classification of the device under
section 513 of the FD&C Act, whichever
is later. Also, a preamendments device
subject to the rulemaking procedure
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 rule requiring the
submission of a PMA for the device. At
that time, an IDE is required only if a
PMA has not been submitted or a PDP
completed.
Section 515(b)(2)(A) of the FD&C Act
provides that a proceeding to issue a
final rule to require premarket approval
shall be initiated by publication of a
notice of proposed rulemaking
containing: (1) The regulation; (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 or a declared completed
PDP and the benefit to the public from
the use of the device; (3) an opportunity
for the submission of comments on the
proposed rule 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)(2)(B) of the FD&C Act
provides that if FDA receives a request
for a change in the classification of the
device within 15 days of the publication
of the notice, FDA shall, within 60 days
of the publication of the notice, consult
with the appropriate FDA advisory
committee and publish a notice denying
the request for change in reclassification
or announcing its intent to initiate a
PO 00000
Frm 00019
Fmt 4702
Sfmt 4702
48063
proceeding to reclassify the device
under section 513(e) of the FD&C Act.
Section 515(b)(3) of the FD&C Act
provides that FDA shall, after the close
of the comment period on the proposed
rule and consideration of any comments
received, issue a final rule 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).
When a proposed rule to require
premarket approval for a
preamendments device is finalized,
section 501(f)(2)(B) of the FD&C Act (21
U.S.C. 351(f)(2)(B)) requires that a PMA
or notice of completion of a PDP for any
such device be filed within 90 days of
the date of issuance of the final rule or
30 months after the final classification
of the device under section 513 of the
FD&C Act, whichever is later. If a PMA
or notice of completion of a PDP is not
filed by the later of the two dates,
commercial distribution of the device is
required to cease since the device would
be deemed adulterated under section
501(f) of the FD&C Act.
The device may, however, be
distributed for investigational use if the
manufacturer, importer, or other
sponsor of the device complies with the
IDE regulations. If a PMA or notice of
completion of a PDP is not filed by the
later of the two dates, and the device
does not comply with IDE regulations,
the device is deemed to be adulterated
within the meaning of section
501(f)(1)(A) of the FD&C Act, and
subject to seizure and condemnation
under section 304 of the FD&C Act (21
U.S.C. 334) if its distribution continues.
Shipment of devices in interstate
commerce will be subject to injunction
under section 302 of the FD&C Act (21
U.S.C. 332), and the individuals
responsible for such shipment will be
subject to prosecution under section 303
of the FD&C Act (21 U.S.C. 333). In the
past, FDA has requested that
manufacturers take action to prevent the
further use of devices for which no PMA
or PDP has been filed and may
determine that such a request is
appropriate for the cranial
electrotherapy stimulator.
The FD&C Act does not permit an
extension of the 90-day period after
issuance of a final rule within which an
application or a notice is required to be
filed. The House Report on the 1976
amendments states that: ‘‘[t]he thirty
month grace period afforded after

classification of a device into class III
* * * is sufficient time for
manufacturers and importers to develop
the data and conduct the investigations
necessary to support an application for
premarket approval (H. Rept. 94–853,
94th Cong., 2d sess. 42 (1976)).’’
The SMDA added section 515(i) to the
FD&C Act requiring FDA to review the
classification of preamendments class III
devices for which no final rule requiring
the submission of PMAs has been
issued, and to determine whether or not
each device should be reclassified into
class I or class II or remain in class III.
For devices remaining in class III, the
SMDA directed FDA to develop a
schedule for issuing regulations to
require premarket approval. The SMDA
does not, however, prevent FDA from
proceeding immediately to rulemaking
under section 515(b) of the FD&C Act on
specific devices, in the interest of public
health, independent of the procedures
of section 515(i). Proceeding directly to
rulemaking under section 515(b) of the
FD&C Act is consistent with Congress’
objective in enacting section 515(i), i.e.,
that preamendments class III devices for
which PMAs have not been previously
required either be reclassified to class I
or class II or be subject to the
requirements of premarket approval.
Moreover, in this proposal, interested
persons are being offered the
opportunity to request reclassification of
the cranial electrotherapy stimulator.
II. Dates New Requirements Apply
In accordance with section 515(b) of
the FD&C Act, FDA is proposing to
require that a PMA or a notice of
completion of a PDP be filed with the
Agency for the cranial electrotherapy
stimulator within 90 days after issuance
of any final rule based on this proposal.
An applicant whose device was legally
in commercial distribution before May
28, 1976, or whose device has been
found to be substantially equivalent to
such a device, will be permitted to
continue marketing such class III
devices during FDA’s review of the
PMA or notice of completion of the
PDP. FDA intends to review any PMA
for the device within 180 days, and any
notice of completion of a PDP for the
device within 90 days of the date of
filing. 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.’’
FDA intends that under § 812.2(d), the
preamble to any final rule based on this
proposal will state that, as of the date on
VerDate Mar<15>2010
18:42 Aug 05, 2011
Jkt 223001
which the filing of a PMA or a notice
of completion of a PDP is required to be
filed, the exemptions from the
requirements of the IDE regulations for
preamendments class III devices in
§ 812.2(c)(1) and (c)(2) will cease to
apply to any device that is: (1) Not
legally on the market on or before that
date or (2) legally on the market on or
before that date but for which a PMA or
notice of completion of a PDP is not
filed by that date, or for which PMA
approval has been denied or withdrawn.
If a PMA or notice of completion of
a PDP for the cranial electrotherapy
stimulator is not filed with FDA within
90 days after the date of issuance of any
final rule requiring premarket approval
for the device, commercial distribution
of the device must cease. The device
may be distributed for investigational
use only if the requirements of the IDE
regulations are met. The requirements
for significant risk devices include
submitting an IDE application to FDA
for its review and approval. An
approved IDE is required to be in effect
before an investigation of the device
may be initiated or continued under
§ 812.30. FDA, therefore, cautions that
IDE applications should be submitted to
FDA at least 30 days before the end of
the 90-day period after the issuance of
the final rule to avoid interrupting
investigations.
III. Proposed Findings With Respect to
Risks and Benefits
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 the cranial electrotherapy
stimulator have an approved PMA or a
declared completed PDP and (2) the
benefits to the public from the use of the
cranial electrotherapy stimulator.
These findings are based on the
reports and recommendations of the
advisory committee (panel) for the
classification of this device along with
information submitted in response to
the 515(i) Order, (74 FR 16214, April 9,
2009), and any additional information
that FDA has encountered. Additional
information regarding the risks as well
as classification associated with this
device type can be found in the
following documents published in the
Federal Register on these dates:

IV. Devices Subject to This Proposal
Cranial electrotherapy stimulator (21
CFR 882.5800)
A. Identification
A cranial electrotheraphy stimulator
is a device that applies electrical current
to a patient’s head to treat insomnia,
depression, or anxiety.
B. Summary of Data
The Neurological Devices Panel that
discussed original classification for the
cranial electrotherapy stimulator (CES)
device in 1977 and 1978 ultimately
recommended that the device be
classified into class III because
satisfactory device effectiveness had not
been demonstrated. The panel
considered information from the
National Research Council, which
reviewed 88 published studies on CES
and concluded that the device has not
been shown to be effective in treating
any of the conditions for which it was
prescribed. In addition, the panel
indicated that it was not possible to
establish an adequate performance
standard for CES because the
characteristics of the electrical current
necessary for potential effectiveness
were not known. The panel believed
that general controls would not provide
sufficient control over these
characteristics, and that the device
presented a potential unreasonable risk
of illness or injury to the patient if the
practitioner relied on the device, and it
was ineffective in treating the patient’s
illness. Therefore, the panel
recommended that premarket approval
was necessary to assure the safety and
effectiveness of CES devices.
In support of a subsequent proposed
rule in 1993 for classification of CES
into class III, FDA performed a literature
review and identified additional studies
that had been performed for CES. After
a review of the scientific literature, FDA
concluded that the effectiveness of CES
had still not been established by
adequate scientific evidence.
FDA has performed a literature search
for studies of CES published after the
1993 proposed rule (January 1, 1993, to
present). Many studies were excluded
from further review because they were
conducted on very specific populations
(e.g., alcoholics or other types of
substance abuse), and therefore were not
representative of the general population
suffering from insomnia, anxiety, or
depression. Six studies were identified
for further review (Refs. 1 through 6).
FDA also identified two relevant metaanalyses (Refs. 7 and 8).
The Bystritsky et al. study (Ref. 1) was
conducted open-label, and on only 12
E:\FR\FM\08AUP1.SGM
08AUP1
emcdonald on DSK2BSOYB1PROD with PROPOSALS
Federal Register / Vol. 76, No. 152 / Monday, August 8, 2011 / Proposed Rules
subjects. The study involved
observational baseline versus posttreatment without a control and
therefore provided insufficient evidence
of safety and effectiveness. The
Heffernan study (Ref. 2) concludes that
a single CES treatment may have
physiologic effects; however, no
outcomes of anxiety, depression or
insomnia were measured and the study
was conducted on only 20 subjects. The
Overcash study (Ref. 3) was a
retrospective study design and used an
anxiety rating scale that was not
validated. The Voris study (Ref. 4)
analyzed only a subgroup of
‘‘psychiatric subjects’’ which included
many types of anxiety disorders as well
as non-anxiety psychiatric disorders.
The subgroup represents a
diagnostically heterogeneous group. The
subgroup analysis was not pre-specified
and the number of subjects per
subgroup was not specified. The Hyun
study (Ref. 5) was a randomized
controlled trial of 60 subjects. However,
the indication under investigation was
preoperative anxiety, which may not be
indicative of an Axis I anxiety disorder.
Moreover, the outcome measure, a 5point Likert scale rating of anxiety, was
not a standardized validated rating
instrument. The Winick study (Ref. 6),
which was a randomized controlled trial
of 33 subjects with anxiety prior to
dental procedures and utilized a 7-point
Likert scale, suffers from the same
limitations as the Hyun study.
The O’Conner meta-analysis (Ref. 7)
examined the effect of CES on reduction
of primary and secondary withdrawal
symptoms among various chemically
dependent populations. The results of
this analysis do not relate to the
question of safety and effectiveness
since the labeled indications for CES
currently include insomnia, depression,
or anxiety, and not withdrawal
symptoms of chemical dependence. The
Klawansky meta-analysis (Ref. 8) was
based on an examination of literature on
CES versus sham treatment. Although
the analysis showed CES to be more
effective than sham for anxiety, the
study populations showed great
heterogeneity of diagnostic categories
(e.g., in many cases anxiety was not the
primary diagnosis, but rather one of a
number of symptomatic outcome
measures collected during a trial).
Therefore, it is unclear whether the
finding can be generalized to support
the effectiveness of CES in
homogeneous populations of
individuals suffering from anxiety,
depression, or insomnia. Also, many of
the studies evaluated in the Klawansky
VerDate Mar<15>2010
18:42 Aug 05, 2011
Jkt 223001
meta-analysis involved insufficient
blinding.
FDA has concluded from a review of
the scientific literature and the
information provided in the 515(i) call
for information (74 FR 16214) that the
effectiveness of CES has not been
established by adequate scientific
evidence and the Agency continues to
agree with the panel’s recommendation.
C. Risks to Health
• Worsening of the condition being
treated—If the device is not effective
and the patient is not treated in a
conventional manner, the patient’s
psychological condition may worsen.
• Skin irritation—The electrodes or
the conductive cream used with the
electrodes may cause skin irritation.
• Headaches—Reported cases of
adverse effects of CES devices include
headaches following treatment with
electrical stimulation.
• Potential risk of seizure—electrical
stimulation of the brain may result in
seizures, particularly in patients with a
history of seizure.
• Blurred vision—placement of
electrodes over the eyes may cause
blurred vision.
• Potential adverse effects from
electrical stimulation of the brain—The
physiological effects associated with
electrical stimulation of the brain by
these devices have not been studied
systematically; therefore, adverse effects
which may be caused by these electrical
stimuli remain unknown.
V. PMA Requirements
A PMA for the cranial electrotherapy
simulator 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 previously, as well as a
discussion of the effectiveness of the
device for which premarket approval is
sought. In addition, a PMA must
include all data and information on: (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 device for its intended use (see
§ 860.7(c)(2)). Valid scientific evidence
is ‘‘evidence from well-controlled
investigations, partially controlled
studies, studies and objective trials

VI. PDP Requirements
A PDP for the cranial electrotherapy
stimulator may be submitted in lieu of
a PMA, and must follow the procedures
outlined in section 515(f) of the FD&C
Act. A PDP must provide: (1) A
description of the device, (2) preclinical
trial information (if any), (3) clinical
trial information (if any), (4) a
description of the manufacturing and
processing of the device, (5) the labeling
of the device, and (6) all other relevant
information about the device. In
addition, the PDP must include progress
reports and records of the trials
conducted under the protocol on the
safety and effectiveness of the device.
VII. 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)(A)(i) through (b)(2)(A)(iv) of
the FD&C Act and § 860.132 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. Any
proceeding to reclassify the device will
be under the authority of section 513(e)
of the FD&C Act.
A request for a change in the
classification of these devices is to be in
the form of a reclassification petition
containing the information required by
§ 860.123, including new information
relevant to the classification of the
device.
The Agency advises that to ensure
timely filing of any such petition, any
request should be submitted to the
Division of Dockets Management (see
ADDRESSES) and not to the address
provided in § 860.123(b)(1). If a timely
request for a change in the classification
of these devices is submitted, the
Agency will, within 60 days after
receipt of the petition, and after
consultation with the appropriate FDA
resources, publish an order in the
Federal Register that either denies the

the device in accordance with section
513(e) of the FD&C Act and 21 CFR
860.130 of the regulations.

VIII. Environmental Impact
The Agency has 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. Analysis of Impacts
FDA has examined the impacts of the
proposed rule under Executive Order
12866, Executive Order 13563, 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 Agencies 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). The Agency
believes that this proposed rule is not a
significant action under Executive Order
12866.
The Regulatory Flexibility Act
requires Agencies to analyze regulatory
options that would minimize any
significant impact of a rule on small
entities. The Agency proposes to certify
that the rule would not have a
significant economic impact on a
substantial number of small entities.
Section 202(a) of the Unfunded
Mandates Reform Act of 1995 requires
that Agencies 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 $136
million, using the most current (2010)
Implicit Price Deflator for the Gross
Domestic Product. FDA does not expect
this proposed rule to result in any oneyear expenditure that would meet or
exceed this amount.
A. Benefits of the Proposed Rule
The proposed requirement for PMAs
or PDPs for CES would generate social
benefits equal to the value of the
information generated by the safety and
VerDate Mar<15>2010

effectiveness tests that CES producers
would be required to conduct under the
proposed call for PMAs or PDPs.
Provided first to FDA, this information
would eventually assist physicians,
patients and insurance providers in
making more informed decisions about
CES.
There is reason to believe that current
decisions about CES use are based on
incomplete information. In their 1995
meta-analysis of CES research,
Klawansky et al. (Ref. 8) find that most
CES studies in the literature are beset
with weaknesses, such as small sample
size, incomplete statistical reporting,
and potential bias from authors who
have commercial interests in CES
products. Klawansky and coauthors also
express concern that only three of the 18
studies they examined were truly
double-blinded, and patient blinding
may have been insufficient in some
cases due to the difficulty of mimicking
in sham treatment the sensation
produced by CES. More recent literature
indicates that there is still much
uncertainty about the safety and
effectiveness of CES.
If consumers, up until now, have been
overestimating the safety and
effectiveness of CES devices, then
demand for these products would
decrease as a result of the call for PMAs
or PDPs, and consumers would
purchase fewer CES devices and
services than under the previous
process whereby CES devices were
cleared under the 510(k) process. For all
the units purchased under the 510(k)
clearance process that would not be
purchased under the PMA or PDP
approval process, society is currently
incurring a cost equal to the difference
between the producer’s cost of
producing that unit and the dollar value
of the health benefit experienced by the
consumer. The avoidance of this cost
represents the per-unit benefit to society
of the proposed requirement for PMAs
or PDPs; summing over all currentlymarketed units yields society’s total
benefit. This sum is bounded above by
current consumer expenditure on CES
devices (further discussion of this point
appears in the Technical Appendix in
section IX.D of this document).
Consumer expenditure on CES can be
approximated by finding total producer
revenue (this is only an approximation
because any applicable taxes drive a
wedge between expenditure and
revenue). FDA estimates that there are
approximately 11 producers currently
marketing CES devices. Six of these
producers appear in FDA’s Data
universal numbering system database,
with sales revenue for the six ranging
from $100,000 to $1.2 million per year.
PO 00000
Frm 00022
Fmt 4702
Sfmt 4702
Manta.com (Ref. 9) reports sales revenue
of less than $0.5 million for one of the
producers not appearing in Data
universal numbering system. (It appears
that few CES producers market non-CES
goods or services, so most of the firms’
revenue can be attributed to CES sales.)
The average annual sales revenue of the
7 producers for whom we have data is
$515,000. Assuming that this average
equals the CES industry’s overall
average yields an estimate of annual
CES producer revenue of 11 ×
$515,000=$5.67 million. As mentioned
previously, in the case where additional
safety and effectiveness information
decreases demand, this revenue total
provides an upper bound on the
estimated benefit to society of requiring
PMAs or PDPs for CES devices.
If the additional testing associated
with class III PMA or PDP were to reveal
that CES devices are safer and more
effective than consumers currently
believe, then demand for these products
would increase. In this case, consumers
currently purchase too few rather than
too many CES devices as a result of
incomplete information, and the benefit
of the requirement for PMAs or PDPs
would come from the increased use and
associated health benefits of the devices.
As discussed in the Technical Appendix
in section IX.D of this document, FDA
cannot in this case estimate a bound on
the total social benefit of requiring
PMAs or PDPs. FDA requests comment
on this issue and on all methods and
results of our benefits estimation.
B. Costs of the Proposed Rule
Under the proposed rule, FDA would
require producers in this industry to
obtain PMA or establish a PDP before
marketing new products. Currently, a
CES producer receives clearance to
market by submitting a 510(k).
Therefore, the rule-induced cost per
new product would be the difference
between the cost of preparing and
submitting a PMA application (which
we assume to be approximately the
same with PDP as with traditional PMA)
and the cost of preparing and submitting
a 510(k) application. Blozan and Tucker
(Ref. 10) estimate the cost of an average
510(k) at $500; since the mean number
of pages for the 510(k) submissions in
their sample is 24, the estimated cost
per page is $21, or $36 after adjusting
for inflation (Ref. 11). FDA records
indicate that, recently, the one or two
cranial electrotherapy stimulator 510(k)
submissions received per year have
consisted of several hundred pages
each. Assuming an average of 300 pages
per submission and a cost per page of
$36 yields an average cost of preparing
and submitting a 510(k) of $11,000. FDA
E:\FR\FM\08AUP1.SGM
08AUP1
Federal Register / Vol. 76, No. 152 / Monday, August 8, 2011 / Proposed Rules
has estimated an upper bound on the
cost of PMA at approximately
$1,000,000 (see, for example, 73 FR
7498 at 7501, February 8, 2008); this
yields a difference of $989,000 between
the costs of PMA and 510(k)
preparation. Multiplying this cost
difference by the recent average of 1.5
new CES submissions per year yields an
annual rule-induced cost equal to $1.48
million. Additionally, producers of CES
products that are already on the market
would need to submit PMA
applications, costing approximately $1
million each. FDA believes that there
are approximately 13 such products, so
there would be a rule-induced upfront
cost of $13 million.
These cost estimates are only correct
if no producers would be dissuaded
from introducing new products or
seeking approval for currently-marketed
products by the cost of submitting a
PMA application or by changes in the
possibility that FDA grants approval. In
cases where producers are dissuaded
from entering or attempting to stay in
the market, the cost to industry of the
proposed rule would be the foregone
expected profit on the withdrawn or
withheld CES devices, which is
necessarily less than the cost of PMA
submission (otherwise, the producers in
question would not be dissuaded from
seeking PMA); the $13 million upfront
and $1.48 million annual estimates
mentioned previously thus provide
upper bounds on the submission-related
cost that would be borne by industry.
Excluded from these totals is the welfare
loss that would be borne by consumers
who would, in the absence of the
proposed rule, use the CES devices that
would be withdrawn or withheld from
the market as a result of the call for
PMAs or PDPs. Due to the lack of
sufficient market data, we cannot
quantify these consumers’ welfare loss.
FDA requests comment on this issue
and on all methods and results of our
cost estimation.
In addition to the cost to industry of
preparing and submitting PMAs or
PDPs, the proposed rule would impose
review costs on FDA. Geiger (Ref. 12)
estimated that, for devices reviewed by
FDA’s Center for Devices and
Radiological Health in 2003 and 2004,
review costs were $563,000 per PMA
and $13,400 per 510(k). Updated for
inflation (with Ref. 11) to 2010 dollars,
these review costs become $653,000 per
PMA and $15,500 per 510(k). Thus, the
proposed rule’s review-related costs are
expected to equal $8.49 million (= 13 ×
$653,000) upfront and $956,000 (= 1.5 ×
[$653,000 ¥$15,500]) per subsequent
year. A portion of this total will be paid
48067
by industry in the form of user fees,
with the remainder coming from general
revenues. The CES manufacturers
currently registered with FDA have
annual revenues well under $100
million, so they would likely be eligible
for small business user fees, which are
currently set at $59,705 for a premarket
application (PMA or PDP) and $2,174
for a 510(k) submission (75 FR 45641 at
45643). Thus, user fees would likely
cover $776,000 (= 13 × $59,705) of
upfront and $86,000 (= 1.5 × [$59,705
¥$2,174]) of subsequent annual ruleinduced review costs. Because annual
revenues for CES manufacturers are also
below $30 million, CES manufacturers
submitting first premarket applications
may qualify for user fee waivers; such
cases would increase the portion of FDA
review costs coming from general
revenues above the current estimates of
$7.71 million upfront and $870,000 per
subsequent year and decrease the
anticipated rule-induced change in user
fee collections.
Table 1 of this document displays all
quantified benefits and costs of the
proposed rule. We reiterate that most of
our estimates represent extreme upper
bounds. For both benefits and costs, the
likely effects of the rule would be much
smaller than the estimates appearing in
table 1.

The Regulatory Flexibility Act
requires Agencies to prepare an initial
regulatory flexibility analysis if a
proposed rule would have a significant
effect on a substantial number of small
businesses, non-profit organizations,
local jurisdictions or other entities. Even
though the producers of CES devices do
tend to be small, only a very few entities
participate in this market. FDA
estimates that there are approximately

11 producers currently marketing CES
devices; there may also be a handful of
affiliated businesses that would be
affected by the requirement for PMAs or
PDPs. Therefore, FDA tentatively
concludes that this proposed rule would
not have a significant economic impact
on a substantial number of small
entities. We request comment on this

XII. Proposed Effective Date
FDA has analyzed this proposed rule
in accordance with the principles set
forth in Executive Order 13132. FDA
has determined that the proposed rule,
if finalized, would not contain policies
that would 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, the Agency tentatively
concludes that the proposed 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.
FDA is proposing that any final rule
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 rule.

Electrotherapy Stimulator
AGENCY: Food and Drug Administration, HHS.
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Food and Drug Administration (FDA) is proposing to require
the filing of a premarket approval application (PMA) or a notice of
completion of a product development protocol (PDP) for the Cranial
Electrotherapy Stimulator. The Agency is also summarizing its proposed
findings regarding the degree of risk of illness or injury designed to
be eliminated or reduced by requiring this device to meet the statute's
approval requirements and the benefits to the public from the use of
the device. In addition, FDA is announcing the opportunity for
interested persons to request that the Agency change the classification
of the cranial electrotherapy stimulator based on new information. This
action implements certain statutory requirements.
DATES: Submit either electronic or written comments by November 7,
2011. Submit requests for a change in classification by August 23,
2011. FDA intends that, if a final rule based on this proposed rule is
issued, anyone who wishes to continue to market the device will need to
submit a PMA within 90 days of the effective date of the final rule.

SUPPLEMENTARY INFORMATION:
I. Background--Regulatory Authorities
The Federal Food, Drug, and Cosmetic Act (the FD&C Act), as amended
by the Medical Device Amendments of 1976 (the 1976 amendments) (Pub. L.
94-295), the Safe Medical Devices Act of 1990 (SMDA) (Pub. L. 101-629),
and the Food and Drug Administration Modernization Act of 1997 (FDAMA)
(Pub. L. 105-115), the Medical Device User Fee and Modernization Act of
2002 (MDUFMA) (Pub. L. 107-250), the Medical Devices Technical
Corrections Act (Pub. L. 108-214), and the Food and Drug Administration
Amendments Act of 2007 (Pub. L. 110-85), among other amendments,
establish 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 categories (classes) of devices, reflecting the
regulatory controls needed to provide reasonable assurance of their
safety and effectiveness. The three categories of devices are class I
(general controls), class II (special controls), and class III
(premarket approval).
Under section 513 of the FD&C Act, devices that were in commercial
distribution before the enactment of the 1976 amendments, May 28, 1976
(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.
Devices that were not in commercial distribution prior to May 28,
1976 (generally referred to as postamendments devices) are
automatically classified by section 513(f) of the FD&C Act into class
III without any FDA rulemaking process. Those devices remain in class
III and require premarket approval unless, and until, the device is
reclassified into class I or II or FDA issues an order finding the
device to be substantially equivalent, in accordance with section
513(i) of the FD&C Act, to a predicate device that does not require
premarket approval. The Agency determines whether new devices are
substantially equivalent to predicate devices by means of premarket
notification procedures in section 510(k) of the FD&C Act (21 U.S.C.
360(k)) and 21 CFR part 807.
A preamendments device that has been classified into class III may
be marketed by means of premarket notification procedures (510(k)
process) without submission of a PMA) until FDA issues a final
regulation under section 515(b) of the FD&C Act (21 U.S.C. 360e(b))
requiring premarket approval. Section 515(b)(1) of the FD&C Act
establishes the requirement that a preamendments device that FDA has
classified into class III is subject to premarket approval. A
preamendments class III device may be commercially distributed without
an approved PMA or a notice of completion of a PDP until 90 days after
FDA issues a final rule requiring premarket approval for the device, or
30 months after final classification of the device under section 513 of
the FD&C Act, whichever is later. Also, a preamendments device subject
to the rulemaking procedure 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 rule
requiring the submission of a PMA for the device. At that time, an IDE
is required only if a PMA has not been submitted or a PDP completed.
Section 515(b)(2)(A) of the FD&C Act provides that a proceeding to
issue a final rule to require premarket approval shall be initiated by
publication of a notice of proposed rulemaking containing: (1) The
regulation; (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 or a declared completed PDP and the
benefit to the public from the use of the device; (3) an opportunity
for the submission of comments on the proposed rule 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)(2)(B) of the FD&C Act provides that if FDA receives
a request for a change in the classification of the device within 15
days of the publication of the notice, FDA shall, within 60 days of the
publication of the notice, consult with the appropriate FDA advisory
committee and publish a notice denying the request for change in
reclassification or announcing its intent to initiate a proceeding to
reclassify the device under section 513(e) of the FD&C Act. Section
515(b)(3) of the FD&C Act provides that FDA shall, after the close of
the comment period on the proposed rule and consideration of any
comments received, issue a final rule 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).
When a proposed rule to require premarket approval for a
preamendments device is finalized, section 501(f)(2)(B) of the FD&C Act
(21 U.S.C. 351(f)(2)(B)) requires that a PMA or notice of completion of
a PDP for any such device be filed within 90 days of the date of
issuance of the final rule or 30 months after the final classification
of the device under section 513 of the FD&C Act, whichever is later. If
a PMA or notice of completion of a PDP is not filed by the later of the
two dates, commercial distribution of the device is required to cease
since the device would be deemed adulterated under section 501(f) of
the FD&C Act.
The device may, however, be distributed for investigational use if
the manufacturer, importer, or other sponsor of the device complies
with the IDE regulations. If a PMA or notice of completion of a PDP is
not filed by the later of the two dates, and the device does not comply
with IDE regulations, the device is deemed to be adulterated within the
meaning of section 501(f)(1)(A) of the FD&C Act, and subject to seizure
and condemnation under section 304 of the FD&C Act (21 U.S.C. 334) if
its distribution continues. Shipment of devices in interstate commerce
will be subject to injunction under section 302 of the FD&C Act (21
U.S.C. 332), and the individuals responsible for such shipment will be
subject to prosecution under section 303 of the FD&C Act (21 U.S.C.
333). In the past, FDA has requested that manufacturers take action to
prevent the further use of devices for which no PMA or PDP has been
filed and may determine that such a request is appropriate for the
cranial electrotherapy stimulator.
The FD&C Act does not permit an extension of the 90-day period
after issuance of a final rule within which an application or a notice
is required to be filed. The House Report on the 1976 amendments states
that: ``[t]he thirty month grace period afforded after
[[Page 48064]]
classification of a device into class III * * * is sufficient time for
manufacturers and importers to develop the data and conduct the
investigations necessary to support an application for premarket
approval (H. Rept. 94-853, 94th Cong., 2d sess. 42 (1976)).''
The SMDA added section 515(i) to the FD&C Act requiring FDA to
review the classification of preamendments class III devices for which
no final rule requiring the submission of PMAs has been issued, and to
determine whether or not each device should be reclassified into class
I or class II or remain in class III. For devices remaining in class
III, the SMDA directed FDA to develop a schedule for issuing
regulations to require premarket approval. The SMDA does not, however,
prevent FDA from proceeding immediately to rulemaking under section
515(b) of the FD&C Act on specific devices, in the interest of public
health, independent of the procedures of section 515(i). Proceeding
directly to rulemaking under section 515(b) of the FD&C Act is
consistent with Congress' objective in enacting section 515(i), i.e.,
that preamendments class III devices for which PMAs have not been
previously required either be reclassified to class I or class II or be
subject to the requirements of premarket approval. Moreover, in this
proposal, interested persons are being offered the opportunity to
request reclassification of the cranial electrotherapy stimulator.
II. Dates New Requirements Apply
In accordance with section 515(b) of the FD&C Act, FDA is proposing
to require that a PMA or a notice of completion of a PDP be filed with
the Agency for the cranial electrotherapy stimulator within 90 days
after issuance of any final rule based on this proposal. An applicant
whose device was legally in commercial distribution before May 28,
1976, or whose device has been found to be substantially equivalent to
such a device, will be permitted to continue marketing such class III
devices during FDA's review of the PMA or notice of completion of the
PDP. FDA intends to review any PMA for the device within 180 days, and
any notice of completion of a PDP for the device within 90 days of the
date of filing. 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.''
FDA intends that under Sec. 812.2(d), the preamble to any final
rule based on this proposal will state that, as of the date on which
the filing of a PMA or a notice of completion of a PDP is required to
be filed, the exemptions from the requirements of the IDE regulations
for preamendments class III devices in Sec. 812.2(c)(1) and (c)(2)
will cease to apply to any device that is: (1) Not legally on the
market on or before that date or (2) legally on the market on or before
that date but for which a PMA or notice of completion of a PDP is not
filed by that date, or for which PMA approval has been denied or
withdrawn.
If a PMA or notice of completion of a PDP for the cranial
electrotherapy stimulator is not filed with FDA within 90 days after
the date of issuance of any final rule requiring premarket approval for
the device, commercial distribution of the device must cease. The
device may be distributed for investigational use only if the
requirements of the IDE regulations are met. The requirements for
significant risk devices include submitting an IDE application to FDA
for its review and approval. An approved IDE is required to be in
effect before an investigation of the device may be initiated or
continued under Sec. 812.30. FDA, therefore, cautions that IDE
applications should be submitted to FDA at least 30 days before the end
of the 90-day period after the issuance of the final rule to avoid
interrupting investigations.
III. Proposed Findings With Respect to Risks and Benefits
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 the
cranial electrotherapy stimulator have an approved PMA or a declared
completed PDP and (2) the benefits to the public from the use of the
cranial electrotherapy stimulator.
These findings are based on the reports and recommendations of the
advisory committee (panel) for the classification of this device along
with information submitted in response to the 515(i) Order, (74 FR
16214, April 9, 2009), and any additional information that FDA has
encountered. Additional information regarding the risks as well as
classification associated with this device type can be found in the
following documents published in the Federal Register on these dates:
November 28, 1974 (43 FR 55716), September 4, 1979 (44 FR 51770),
January 6, 1989 (54 FR 550), August 31, 1993 (58 FR 45865), August 24,
1995 (60 FR 43967), November 22, 1996 (61 FR 59448), January 28, 1997
(62 FR 4023), and June 4, 1997 (62 FR 30456 and 62 FR 30600).
IV. Devices Subject to This Proposal
Cranial electrotherapy stimulator (21 CFR 882.5800)
A. Identification
A cranial electrotheraphy stimulator is a device that applies
electrical current to a patient's head to treat insomnia, depression,
or anxiety.
B. Summary of Data
The Neurological Devices Panel that discussed original
classification for the cranial electrotherapy stimulator (CES) device
in 1977 and 1978 ultimately recommended that the device be classified
into class III because satisfactory device effectiveness had not been
demonstrated. The panel considered information from the National
Research Council, which reviewed 88 published studies on CES and
concluded that the device has not been shown to be effective in
treating any of the conditions for which it was prescribed. In
addition, the panel indicated that it was not possible to establish an
adequate performance standard for CES because the characteristics of
the electrical current necessary for potential effectiveness were not
known. The panel believed that general controls would not provide
sufficient control over these characteristics, and that the device
presented a potential unreasonable risk of illness or injury to the
patient if the practitioner relied on the device, and it was
ineffective in treating the patient's illness. Therefore, the panel
recommended that premarket approval was necessary to assure the safety
and effectiveness of CES devices.
In support of a subsequent proposed rule in 1993 for classification
of CES into class III, FDA performed a literature review and identified
additional studies that had been performed for CES. After a review of
the scientific literature, FDA concluded that the effectiveness of CES
had still not been established by adequate scientific evidence.
FDA has performed a literature search for studies of CES published
after the 1993 proposed rule (January 1, 1993, to present). Many
studies were excluded from further review because they were conducted
on very specific populations (e.g., alcoholics or other types of
substance abuse), and therefore were not representative of the general
population suffering from insomnia, anxiety, or depression. Six studies
were identified for further review (Refs. 1 through 6). FDA also
identified two relevant meta-analyses (Refs. 7 and 8).
The Bystritsky et al. study (Ref. 1) was conducted open-label, and
on only 12
[[Page 48065]]
subjects. The study involved observational baseline versus post-
treatment without a control and therefore provided insufficient
evidence of safety and effectiveness. The Heffernan study (Ref. 2)
concludes that a single CES treatment may have physiologic effects;
however, no outcomes of anxiety, depression or insomnia were measured
and the study was conducted on only 20 subjects. The Overcash study
(Ref. 3) was a retrospective study design and used an anxiety rating
scale that was not validated. The Voris study (Ref. 4) analyzed only a
subgroup of ``psychiatric subjects'' which included many types of
anxiety disorders as well as non-anxiety psychiatric disorders. The
subgroup represents a diagnostically heterogeneous group. The subgroup
analysis was not pre-specified and the number of subjects per subgroup
was not specified. The Hyun study (Ref. 5) was a randomized controlled
trial of 60 subjects. However, the indication under investigation was
preoperative anxiety, which may not be indicative of an Axis I anxiety
disorder. Moreover, the outcome measure, a 5-point Likert scale rating
of anxiety, was not a standardized validated rating instrument. The
Winick study (Ref. 6), which was a randomized controlled trial of 33
subjects with anxiety prior to dental procedures and utilized a 7-point
Likert scale, suffers from the same limitations as the Hyun study.
The O'Conner meta-analysis (Ref. 7) examined the effect of CES on
reduction of primary and secondary withdrawal symptoms among various
chemically dependent populations. The results of this analysis do not
relate to the question of safety and effectiveness since the labeled
indications for CES currently include insomnia, depression, or anxiety,
and not withdrawal symptoms of chemical dependence. The Klawansky meta-
analysis (Ref. 8) was based on an examination of literature on CES
versus sham treatment. Although the analysis showed CES to be more
effective than sham for anxiety, the study populations showed great
heterogeneity of diagnostic categories (e.g., in many cases anxiety was
not the primary diagnosis, but rather one of a number of symptomatic
outcome measures collected during a trial). Therefore, it is unclear
whether the finding can be generalized to support the effectiveness of
CES in homogeneous populations of individuals suffering from anxiety,
depression, or insomnia. Also, many of the studies evaluated in the
Klawansky meta-analysis involved insufficient blinding.
FDA has concluded from a review of the scientific literature and
the information provided in the 515(i) call for information (74 FR
16214) that the effectiveness of CES has not been established by
adequate scientific evidence and the Agency continues to agree with the
panel's recommendation.
C. Risks to Health
Worsening of the condition being treated--If the device is
not effective and the patient is not treated in a conventional manner,
the patient's psychological condition may worsen.
Skin irritation--The electrodes or the conductive cream
used with the electrodes may cause skin irritation.
Headaches--Reported cases of adverse effects of CES
devices include headaches following treatment with electrical
stimulation.
Potential risk of seizure--electrical stimulation of the
brain may result in seizures, particularly in patients with a history
of seizure.
Blurred vision--placement of electrodes over the eyes may
cause blurred vision.
Potential adverse effects from electrical stimulation of
the brain--The physiological effects associated with electrical
stimulation of the brain by these devices have not been studied
systematically; therefore, adverse effects which may be caused by these
electrical stimuli remain unknown.
V. PMA Requirements
A PMA for the cranial electrotherapy simulator 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
previously, as well as a discussion of the effectiveness of the device
for which premarket approval is sought. In addition, a PMA must include
all data and information on: (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 device for
its intended use (see Sec. 860.7(c)(2)). Valid scientific evidence is
``evidence from well-controlled investigations, partially controlled
studies, studies and objective trials without matched controls, well-
documented case histories conducted by qualified experts, and reports
of significant human experience with a marketed device, from which it
can fairly and responsibly be concluded by qualified experts that there
is reasonable assurance of the safety and effectiveness of a device
under its conditions of use. * * * Isolated case reports, random
experience, reports lacking sufficient details to permit scientific
evaluation, and unsubstantiated opinions are not regarded as valid
scientific evidence to show safety or effectiveness. * * *'' (21 CFR
860.7(c)(2)).
VI. PDP Requirements
A PDP for the cranial electrotherapy stimulator may be submitted in
lieu of a PMA, and must follow the procedures outlined in section
515(f) of the FD&C Act. A PDP must provide: (1) A description of the
device, (2) preclinical trial information (if any), (3) clinical trial
information (if any), (4) a description of the manufacturing and
processing of the device, (5) the labeling of the device, and (6) all
other relevant information about the device. In addition, the PDP must
include progress reports and records of the trials conducted under the
protocol on the safety and effectiveness of the device.
VII. 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)(A)(i) through
(b)(2)(A)(iv) of the FD&C Act and Sec. 860.132 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. Any proceeding to reclassify the device will be under
the authority of section 513(e) of the FD&C Act.
A request for a change in the classification of these devices is to
be in the form of a reclassification petition containing the
information required by Sec. 860.123, including new information
relevant to the classification of the device.
The Agency advises that to ensure timely filing of any such
petition, any request should be submitted to the Division of Dockets
Management (see ADDRESSES) and not to the address provided in Sec.
860.123(b)(1). If a timely request for a change in the classification
of these devices is submitted, the Agency will, within 60 days after
receipt of the petition, and after consultation with the appropriate
FDA resources, publish an order in the Federal Register that either
denies the
[[Page 48066]]
request or gives notice of its intent to initiate a change in the
classification of the device in accordance with section 513(e) of the
FD&C Act and 21 CFR 860.130 of the regulations.
VIII. Environmental Impact
The Agency has 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. Analysis of Impacts
FDA has examined the impacts of the proposed rule under Executive
Order 12866, Executive Order 13563, 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 Agencies 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). The Agency believes that this proposed rule is not a
significant action under Executive Order 12866.
The Regulatory Flexibility Act requires Agencies to analyze
regulatory options that would minimize any significant impact of a rule
on small entities. The Agency proposes to certify that the rule would
not have a significant economic impact on a substantial number of small
entities.
Section 202(a) of the Unfunded Mandates Reform Act of 1995 requires
that Agencies 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 $136 million, using the most current (2010) Implicit
Price Deflator for the Gross Domestic Product. FDA does not expect this
proposed rule to result in any one-year expenditure that would meet or
exceed this amount.
A. Benefits of the Proposed Rule
The proposed requirement for PMAs or PDPs for CES would generate
social benefits equal to the value of the information generated by the
safety and effectiveness tests that CES producers would be required to
conduct under the proposed call for PMAs or PDPs. Provided first to
FDA, this information would eventually assist physicians, patients and
insurance providers in making more informed decisions about CES.
There is reason to believe that current decisions about CES use are
based on incomplete information. In their 1995 meta-analysis of CES
research, Klawansky et al. (Ref. 8) find that most CES studies in the
literature are beset with weaknesses, such as small sample size,
incomplete statistical reporting, and potential bias from authors who
have commercial interests in CES products. Klawansky and coauthors also
express concern that only three of the 18 studies they examined were
truly double-blinded, and patient blinding may have been insufficient
in some cases due to the difficulty of mimicking in sham treatment the
sensation produced by CES. More recent literature indicates that there
is still much uncertainty about the safety and effectiveness of CES.
If consumers, up until now, have been overestimating the safety and
effectiveness of CES devices, then demand for these products would
decrease as a result of the call for PMAs or PDPs, and consumers would
purchase fewer CES devices and services than under the previous process
whereby CES devices were cleared under the 510(k) process. For all the
units purchased under the 510(k) clearance process that would not be
purchased under the PMA or PDP approval process, society is currently
incurring a cost equal to the difference between the producer's cost of
producing that unit and the dollar value of the health benefit
experienced by the consumer. The avoidance of this cost represents the
per-unit benefit to society of the proposed requirement for PMAs or
PDPs; summing over all currently-marketed units yields society's total
benefit. This sum is bounded above by current consumer expenditure on
CES devices (further discussion of this point appears in the Technical
Appendix in section IX.D of this document).
Consumer expenditure on CES can be approximated by finding total
producer revenue (this is only an approximation because any applicable
taxes drive a wedge between expenditure and revenue). FDA estimates
that there are approximately 11 producers currently marketing CES
devices. Six of these producers appear in FDA's Data universal
numbering system database, with sales revenue for the six ranging from
$100,000 to $1.2 million per year. Manta.com (Ref. 9) reports sales
revenue of less than $0.5 million for one of the producers not
appearing in Data universal numbering system. (It appears that few CES
producers market non-CES goods or services, so most of the firms'
revenue can be attributed to CES sales.) The average annual sales
revenue of the 7 producers for whom we have data is $515,000. Assuming
that this average equals the CES industry's overall average yields an
estimate of annual CES producer revenue of 11 x $515,000=$5.67 million.
As mentioned previously, in the case where additional safety and
effectiveness information decreases demand, this revenue total provides
an upper bound on the estimated benefit to society of requiring PMAs or
PDPs for CES devices.
If the additional testing associated with class III PMA or PDP were
to reveal that CES devices are safer and more effective than consumers
currently believe, then demand for these products would increase. In
this case, consumers currently purchase too few rather than too many
CES devices as a result of incomplete information, and the benefit of
the requirement for PMAs or PDPs would come from the increased use and
associated health benefits of the devices. As discussed in the
Technical Appendix in section IX.D of this document, FDA cannot in this
case estimate a bound on the total social benefit of requiring PMAs or
PDPs. FDA requests comment on this issue and on all methods and results
of our benefits estimation.
B. Costs of the Proposed Rule
Under the proposed rule, FDA would require producers in this
industry to obtain PMA or establish a PDP before marketing new
products. Currently, a CES producer receives clearance to market by
submitting a 510(k). Therefore, the rule-induced cost per new product
would be the difference between the cost of preparing and submitting a
PMA application (which we assume to be approximately the same with PDP
as with traditional PMA) and the cost of preparing and submitting a
510(k) application. Blozan and Tucker (Ref. 10) estimate the cost of an
average 510(k) at $500; since the mean number of pages for the 510(k)
submissions in their sample is 24, the estimated cost per page is $21,
or $36 after adjusting for inflation (Ref. 11). FDA records indicate
that, recently, the one or two cranial electrotherapy stimulator 510(k)
submissions received per year have consisted of several hundred pages
each. Assuming an average of 300 pages per submission and a cost per
page of $36 yields an average cost of preparing and submitting a 510(k)
of $11,000. FDA
[[Page 48067]]
has estimated an upper bound on the cost of PMA at approximately
$1,000,000 (see, for example, 73 FR 7498 at 7501, February 8, 2008);
this yields a difference of $989,000 between the costs of PMA and
510(k) preparation. Multiplying this cost difference by the recent
average of 1.5 new CES submissions per year yields an annual rule-
induced cost equal to $1.48 million. Additionally, producers of CES
products that are already on the market would need to submit PMA
applications, costing approximately $1 million each. FDA believes that
there are approximately 13 such products, so there would be a rule-
induced upfront cost of $13 million.
These cost estimates are only correct if no producers would be
dissuaded from introducing new products or seeking approval for
currently-marketed products by the cost of submitting a PMA application
or by changes in the possibility that FDA grants approval. In cases
where producers are dissuaded from entering or attempting to stay in
the market, the cost to industry of the proposed rule would be the
foregone expected profit on the withdrawn or withheld CES devices,
which is necessarily less than the cost of PMA submission (otherwise,
the producers in question would not be dissuaded from seeking PMA); the
$13 million upfront and $1.48 million annual estimates mentioned
previously thus provide upper bounds on the submission-related cost
that would be borne by industry. Excluded from these totals is the
welfare loss that would be borne by consumers who would, in the absence
of the proposed rule, use the CES devices that would be withdrawn or
withheld from the market as a result of the call for PMAs or PDPs. Due
to the lack of sufficient market data, we cannot quantify these
consumers' welfare loss. FDA requests comment on this issue and on all
methods and results of our cost estimation.
In addition to the cost to industry of preparing and submitting
PMAs or PDPs, the proposed rule would impose review costs on FDA.
Geiger (Ref. 12) estimated that, for devices reviewed by FDA's Center
for Devices and Radiological Health in 2003 and 2004, review costs were
$563,000 per PMA and $13,400 per 510(k). Updated for inflation (with
Ref. 11) to 2010 dollars, these review costs become $653,000 per PMA
and $15,500 per 510(k). Thus, the proposed rule's review-related costs
are expected to equal $8.49 million (= 13 x $653,000) upfront and
$956,000 (= 1.5 x [$653,000 -$15,500]) per subsequent year. A portion
of this total will be paid by industry in the form of user fees, with
the remainder coming from general revenues. The CES manufacturers
currently registered with FDA have annual revenues well under $100
million, so they would likely be eligible for small business user fees,
which are currently set at $59,705 for a premarket application (PMA or
PDP) and $2,174 for a 510(k) submission (75 FR 45641 at 45643). Thus,
user fees would likely cover $776,000 (= 13 x $59,705) of upfront and
$86,000 (= 1.5 x [$59,705 -$2,174]) of subsequent annual rule-induced
review costs. Because annual revenues for CES manufacturers are also
below $30 million, CES manufacturers submitting first premarket
applications may qualify for user fee waivers; such cases would
increase the portion of FDA review costs coming from general revenues
above the current estimates of $7.71 million upfront and $870,000 per
subsequent year and decrease the anticipated rule-induced change in
user fee collections.
Table 1 of this document displays all quantified benefits and costs
of the proposed rule. We reiterate that most of our estimates represent
extreme upper bounds. For both benefits and costs, the likely effects
of the rule would be much smaller than the estimates appearing in table
1.

C. Impact on Small Entities
The Regulatory Flexibility Act requires Agencies to prepare an
initial regulatory flexibility analysis if a proposed rule would have a
significant effect on a substantial number of small businesses, non-
profit organizations, local jurisdictions or other entities. Even
though the producers of CES devices do tend to be small, only a very
few entities participate in this market. FDA estimates that there are
approximately 11 producers currently marketing CES devices; there may
also be a handful of affiliated businesses that would be affected by
the requirement for PMAs or PDPs. Therefore, FDA tentatively concludes
that this proposed rule would not have a significant economic impact on
a substantial number of small entities. We request comment on this
issue.
D. Technical Appendix
The supply-demand diagrams of figure 1 of this document illustrate
the changes in the market for CES devices and services that would occur
if the additional testing associated with class III pre-market approval
were to reveal that CES devices are less safe and effective than
consumers currently believe. In Panel A, the benefit of proposed
requirement for PMAs or PDPs is represented by the shaded area below
[[Page 48068]]
the current market supply curve, above the better-informed, post-call
for PMA demand curve (Demand1) and between the old and new quantities
purchased (determined by the intersections of the pre- and post-call
for PMAs or PDPs demand curves with the current supply curve or the
vertical axis). A similar shaded benefit area appears in Panel B, but
in that case, there is an offsetting loss (shown as the shaded triangle
between the pre- and post-call for PMAs or PDPs supply curves) caused
by CES producers passing on some costs related to PMAs and PDPs to
consumers and consumers therefore purchasing even fewer CES devices or
services than new information indicates they should. The overall
benefit of the rule in Panel B is the difference between the areas of
the Benefit and Loss triangles. In both panels of Figure 1, total CES
spending by consumers, equal to the revenue collected by CES producers
and shown as the rectangle LMNO, provides an upper bound on the amount
of the shaded rule-induced social benefit. While total spending/revenue
always provides an overestimate of the social benefit, the amount of
the over-estimation may range from moderate, as in Panel A (the case in
which CES products disappear from the market), to extreme, as in Panel
B (the case in which there is continued use of at least some CES
products).
[GRAPHIC] [TIFF OMITTED] TP08AU11.171
If the additional testing associated with class III marketing
approval increases consumers' confidence in the safety and
effectiveness of CES devices, then demand for these products would
increase, as depicted in figure 2 of this document. In this case,
consumers currently purchase too few rather than too many CES devices
and services as a result of incomplete information. The benefit to
society of providing information can, as in Panel A of figure 1, be
depicted graphically as the area between the pre-call for PMA or PDP
supply curve and the post-call for PMA or PDP demand curve, and between
the old and new quantities consumed (determined by the intersections of
the pre- and post-call for PMA or PDP demand curves with the pre- and
post-call for PMA or PDP supply curves), but because the revenue
rectangle LMNO does not contain the shaded benefit area, FDA cannot in
this case estimate a bound on the total social benefit.

X. Federalism
FDA has analyzed this proposed rule in accordance with the
principles set forth in Executive Order 13132. FDA has determined that
the proposed rule, if finalized, would not contain policies that would
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, the Agency tentatively concludes that the proposed 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. Paperwork Reduction Act of 1995
This proposed rule refers to currently approved collections of
information found in FDA regulations. These collections of information
are subject to review by the Office of Management and Budget (OMB)
under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). The
collections of information in 21 CFR part 812 have been approved under
OMB control number 0910-0078; the collections of information in 21 CFR
part 814, subpart B, have been approved under OMB control number 0910-
0231; and the collections of information under 21 CFR part 801 have
been approved under OMB control number 0910-0485.
XII. Proposed Effective Date
FDA is proposing that any final rule 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 rule.
