Citizen Petition Regarding the Food and Drug Administration's
Policy on Promotion of Unapproved Uses of Approved Drugs and Devices;
Request for Comments
AGENCY: Food and Drug Administration, HHS.
ACTION: Notice; request for comments.
-----------------------------------------------------------------------
SUMMARY: The Food and Drug Administration (FDA) is requesting comment
on a citizen petition from the Washington Legal Foundation (WLF). The
petition requests that FDA withdraw the document entitled, ``Draft
Policy Statement on Industry-Supported Scientific and Educational
Activities,'' (hereinafter referred to as the draft policy statement)
which was published in the Federal Register on November 27, 1992. The
draft policy statement was intended to provide guidance concerning
educational and scientific activities that may be supported by industry
without causing them to be regulated as advertising or promotional
labeling. The draft policy statement was intended to facilitate the
flow of reliable information about FDA-regulated products. Nonetheless,
the petition claims that the draft policy statement and FDA's
regulation of the promotion of unapproved uses generally are contrary
to the First Amendment's protection of speech and interfere with health
care professionals' provision of effective medical care. The petition
requests that FDA formally adopt a policy stating that, while drug and
medical device manufacturers should not label their products for
unapproved uses, they will not be subject to regulatory action for
facilitating the dissemination of ``truthful'' information about such
unapproved uses. This notice requests comments on the petition and
certain questions regarding the draft policy statement and FDA
regulation of promotion of unapproved uses.
DATES: Submit written comments by February 16, 1995.
ADDRESSES: Written comments to the Dockets Management Branch (HFA-305),
Food and Drug Administration, rm. 1-23, 12420 Parklawn Dr., Rockville,
MD 20857.
FOR FURTHER INFORMATION CONTACT: Ilisa B. G. Bernstein or Philip L.
Chao, Office of Policy (HF-23), Food and Drug Administration, 5600

SUPPLEMENTARY INFORMATION:
I. Background
Traditionally, FDA has regarded industry-supported communication,
including scientific and educational activities on human and animal
drugs, biologic products, and medical devices for health care
professionals, as activities subject to regulation.
In general, under the Federal Food, Drug, and Cosmetic Act (the
act) and the Public Health Service Act, any person who wishes to
introduce or deliver for introduction into interstate commerce any new
drug, biological product, or new animal drug must demonstrate that the
product is safe and effective for its intended uses (see sections
505(a) and 512(a) of the act (21 U.S.C. 355(a) and 360b(a)) and section
351 of the Public Health Service Act (42 U.S.C. 262)). Any person who
wishes to introduce or deliver for introduction into interstate
commerce a new medical device must either demonstrate that the device
is safe and effective for its intended uses or that it is substantially
equivalent to another device for which such a showing is not required.
(See sections 510(k), 513(f), and 515(a) of the act (21 U.S.C. 360(k),
360c(f), 360e(a)).) Such demonstrations of product safety and efficacy
usually consist of data and information derived from clinical
investigations and presented as part of a marketing application. The
marketing application also contains information regarding the product's
intended uses, the patient population (including any special
conditions, restrictions, or limitations for segments of the
population, such as children, pregnant women, or the elderly),
potential adverse events associated with the product's use, and
technical information about the product (see, e.g., 21 CFR 314.50,
514.1, 601.25, and 814.20). If FDA agrees that a product is safe and
effective for its intended use, as reflected in the marketing
application, it approves the application and the product's professional
labeling.\1\ The uses that are approved by the agency are sometimes
referred to as ``labeled'' uses because they appear in the product's
approved labeling. Uses that do not appear in the labeling and are not
approved by the agency are referred to as ``unapproved,''
``unlabeled,'' ``off-label,'' or ``extra-label'' uses.
---------------------------------------------------------------------------
\1\In the case of biologic products, the firm must initially
file both an establishment license application and a product license
application. Upon simultaneous approval, the firm is granted a U.S.
license. Once licensed, the firm may enter the licensed product into
interstate commerce.
---------------------------------------------------------------------------
If labeling for a drug or device fails to contain adequate
directions for use, the drug or device may be deemed to be misbranded
under section 502(f) of the act (21 U.S.C. 352(f)) and subject to
seizure and other penalties.\2\ Prescription drugs, prescription
medical devices, and restricted medical devices are also misbranded
unless ``all advertisements and other descriptive printed matter issued
or caused to be issued by the manufacturer, packer, or distributor''
contain a brief summary or statement of the product's effectiveness or
intended uses, side effects, and contraindications (see sections 502(n)
and 502(r) of the act (21 U.S.C. 352(n) and 352(r))). A drug or device
is misbranded in accordance with section 502(a) of the act (21 U.S.C.
352(a)) if its labeling is false or misleading. Additionally, medical
devices are considered to be misbranded under section 502(o) of the act
(21 U.S.C. 352(o)) if a notice or other information was not provided in
accordance with the provisions of section 510(k) of the act. The
listing of unapproved uses in the labeling or advertising of an
approved device results in an adulterated medical device under section
501(f)(1)(B) of the act (21 U.S.C. 351(f)(1)(B)).
---------------------------------------------------------------------------
\2\Biological products are also drugs or devices and, therefore,
subject to regulation under the misbranding provisions of the act.
---------------------------------------------------------------------------
FDA has long regulated drugs and devices (including biological
products and animal drugs) based on the intended uses for the products.
Under section 201 of the act (21 U.S.C. 321), which defines the terms
``drug'' and ``device,'' the intended use of an article determines
whether the article is a drug or a device. The package insert or
product manual (approved professional labeling) which, for approved
and/or licensed products, physically accompanies the approved product,
sets forth the uses for which the product has been demonstrated to be
safe and effective. The package insert and product manual are not,
however, the sole means by which manufacturers provide information on
their products to health care professionals and consumers. The agency
thus regulates products based not only on information provided ``with''
the product, but also based on information disseminated by
manufacturers in other contexts, such as scientific and educational
meetings and symposia, books, and articles, in part because all of
these materials can create new intended uses for the products, which
must be reflected in the labeling of the products.
This longstanding regulatory scheme has been challenged in a
citizen petition filed by the WLF on October 22, 1993 (Docket No. 92N-
0434/CP1). The petitioner asks FDA to adopt a formal new policy that:
* * * recognizes the important role played by off-label uses of
approved drugs and medical devices in the proper administration of
health care * * * and that declares that FDA will not interfere in
non-labeling activities of drug and medical device manufacturers
whose effect is to promote--through the dissemination of truthful
medical information--off-label [unapproved] uses of approved drugs
and medical devices.
(See petition at page 3.)
The petitioner requests specifically that the agency withdraw its Draft
Policy Statement on Industry-Supported Scientific and Educational
Activities (57 FR 56412, November 27, 1992), see petition at page 3,
and acknowledge that manufacturers can provide information on
unapproved uses through the dissemination of books and through
scientific and educational activities for health care professionals.
(See petition at pages 7 through 12, and 17.)
In support of this position, the petitioner argues that the
agency's policy on promotion of unapproved uses is detrimental to
patient care. The petitioner asserts that oncologists and orthopedic
physicians commonly use approved drugs and devices for unapproved
indications and believes that the public interest is best served by the
widest possible dissemination of accurate information about unapproved
uses. The petitioner views FDA's policy as contrary to this interest
and asserts that FDA intends to prevent the dissemination of
information on unapproved uses and eliminate all unapproved uses of
approved drugs and medical devices. (See petition at page 11.)
The petitioner also argues that FDA's policy is legally unsound.
The petitioner asserts that the act does not provide authority for such
a policy and that the policy violates the First Amendment to the
Constitution.
The petition is based, in part, on erroneous interpretations of FDA
policy. The petitioner asserts, without basis, that FDA fails to
acknowledge the importance to physicians of reliable information on
unapproved uses, that FDA seeks to eliminate all dissemination of
information on unapproved uses, and ultimately, that FDA intends to
eliminate all unapproved uses of FDA-regulated products by physicians.
FDA disagrees with the petition's characterization of FDA policy.
The draft policy statement does not prohibit discussion of unapproved
uses. However, based on its experience, FDA has found that the
promotion of unapproved uses by manufacturers of the promoted products
can subject patients to unnecessary and dangerous risks. Nevertheless,
because the petition raises fundamental questions regarding FDA's
regulation of the safety and effectiveness of therapeutic and
diagnostic products, FDA believes that a full airing of these issues,
with an opportunity for all interested parties to comment in writing,
will be useful to the agency, the regulated industry, and the
interested public.
II. FDA Policy on Promotion of Unapproved Uses
Over a decade ago, the FDA Drug Bulletin informed the medical
community that ``once a [drug] product has been approved for marketing,
a physician may prescribe it for uses or in treatment regimens of
patient populations that are not included in approved labeling.'' The
publication further stated that:
`unapproved' or, more precisely, `unlabeled' uses may be
appropriate and rational in certain circumstances, and may, in fact
reflect approaches to drug therapy that have been extensively
reported in medical literature * * * Valid new uses for drugs
already on the market are often first discovered through
serendipitous observations and therapeutic innovations, subsequently
confirmed by well-planned and executed clinical investigations.
(See FDA Drug Bulletin 12:4-5, 1982.)\3\
---------------------------------------------------------------------------
\3\Similarly, the agency does not intervene in unapproved use of
devices in the absence of a significant public health concern or
significant risk to the patient.
---------------------------------------------------------------------------
The agency and its representatives have restated this policy on
numerous occasions.\4\
---------------------------------------------------------------------------
\4\FDA representatives have described the policy in professional
journals, e.g., Nightingale, S. L., ``Use of Drugs for Unlabeled
Indications,'' American Family Physician, 269, September 1986,
Nightingale, S. L., ``Unlabeled Use of Approved Drugs,'' Drug
Information Journal, 26:141-147, 1992, and in public meetings, e.g.,
Young, F. E., ``Paying for Progress: Reimbursement and Regulated
Medical Products: Speech for the Blue Cross and Blue Shield
Association,'' Technology Management Conference, Chicago, November
1, 1988.
---------------------------------------------------------------------------
At the same time, FDA recognizes the need to ensure that data are
generated from adequate and well-controlled studies to determine a
product's safety and effectiveness for its intended uses and that the
label of the product can be updated to reflect the new uses. Promotion
of unapproved uses can encourage physicians and patients to make
decisions based on statements or claims that are, in many cases,
supported by little or no data. Thus, FDA's position is that the
promotion of unapproved uses, either by companies or other parties that
benefit by the promotion, can place physicians and patients in
positions where they cannot make an informed, unbiased decision. It can
also decrease the incentive of sponsors to conduct the well-controlled
clinical investigations that are necessary to demonstrate whether the
products are safe and effective for their intended uses. Without well-
controlled trials, physicians will not have the information needed to
optimally use the product.
A product's intended use is usually primarily a function of the
manner in which a company characterizes its product in the marketplace.
The agency's focus on the company's characterization of its product in
the marketplace leads naturally to an examination of information
disseminated by or on behalf of a company, in addition to the approved
labeling that physically accompanies the product. The indications for
use set forth in the approved labeling provided with the product may
not necessarily reflect the uses for which the company is actually
marketing its product. The agency's experience over the years in
regulating drug and device safety and effectiveness has demonstrated
that regulatory control over package inserts, user manuals, and
traditional advertising formats may be rendered meaningless if the
company is free to engage in aggressive promotion outside of these
formats. The agency has thus traditionally evaluated the promotion of
drugs and devices through various other avenues of communication,
including books, reprints of articles from scientific journals, and
scientific and educational symposia, to determine whether the products
are being improperly promoted with respect to the approved labeling for
the product.
This longstanding policy is best reflected in the agency's
application of the statutory requirement that the labeling of drugs and
devices bear adequate directions for use. (See section 502(f)(1) of the
act). The courts have agreed with the agency that this provision
requires information not only on how the product is to be used, but
also on what the product is to be used for. In Alberty Food Products
Co. v. United States, 185 F.2d 321, 325 (9th Cir. 1950), the United
States Court of Appeals for the Ninth Circuit found a product to be
misbranded because its labeling failed to bear a description of
therapeutic uses suggested by the company in newspaper advertisements.
Following the Alberty case, the agency promulgated a regulation
providing that the company's responsibility to provide labeling for all
intended uses is broad and objective, and reaches uses suggested
outside of traditional labeling and advertising formats. The regulation
provides, in relevant part, that the term ``intended uses'' refers to:
* * * the objective intent of the persons legally responsible
for the labeling of drugs. The intent is determined by such persons'
expressions or may be shown by the circumstances surrounding the
distribution of the article. This objective intent may, for example,
be shown by labeling claims, advertising matter, or oral or written
statements by such persons or their representatives. It may be shown
by the circumstances that the article is, with the knowledge of such
persons or their representatives, offered and used for a purpose for
which it is neither labeled nor advertised. * * *
(See 21 CFR 201.128. See also 21 CFR 801.4; United States v. Three
Cartons, More or Less, ``No. 26 Formula GM etc.,'' 132 F. Supp. 569,
574 (S.D. Cal. 1952).)
Information disseminated by companies in contexts such as
scientific and educational meetings, symposia, books, and articles may
provide evidence of a regulated product's intended use. If these
formats include statements promoting a use that is inconsistent with
the product's approved labeling, the product is misbranded for failure
to bear labeling with adequate directions for use.
FDA also finds support for its policy of examining a broad array of
information disseminated by companies in the general grant of authority
over labeling and advertisements. Section 201(m) of the act defines the
term ``labeling'' to include all ``written, printed, or graphic''
materials ``accompanying'' a regulated product. The Supreme Court has
agreed with the agency that this definition is not limited to materials
that physically accompany a product. ``Labeling'' may include materials
that supplement or explain a product that are disseminated in direct
mail, and/or otherwise distributed by or on behalf of the company. The
Court has deemed the textual relationship between the materials and the
products to be fundamental. (Kordel v. United States, 335 U.S. 345,
349-350 (1948).)\5\
---------------------------------------------------------------------------
\5\See also United States v. Urbuteit, 335 U.S. 355 (1948);
United States v. Articles of Drug * * * ``Cal's Tupelo Blossom U.S.
Fancy Pure Honey,'' 344 F. 2d 288 (6th Cir. 1965); United States v.
Articles of Drug, 32 F.R.D. 32 (S.D. Ill. 1963); United States v.
Eight Cartons Containing ``Plantation `the Original' etc.,
Molasses,'' 103 F. Supp. 626, 627 (W.D. N.Y. 1951).
---------------------------------------------------------------------------
The agency has adopted a similar interpretation of the term
``advertisement,'' which appears in section 502(n) of the act
(prescription drugs), and in section 502(q) of the act (restricted
devices). Although the act does not define the term ``advertisement,''
section 502(n) of the act indicates that ``advertising'' does not
include materials regulated as labeling. In addition, the legislative
histories of the 1938 act and the 1962 amendments to the act support a
broad construction of what constitutes ``advertising.'' Thus, the
agency interprets the term advertisement to include information (other
than labeling) that originates from the same source as the product and
that is intended to supplement or explain the product. (See also 21 CFR
801.109(d) that states a prescription medical device must bear, among
other things, labeling containing adequate directions for use for all
advertised uses or it may be considered to be misbranded.)
The statutory requirement of adequate directions for use and the
statutory concepts of labeling and advertisements limit the ability of
companies to disseminate information on unapproved uses. However,
because the agency recognizes the importance of dissemination of
reliable scientific information on both approved and unapproved uses,
it has developed a number of policies related to dissemination of such
information.
In October 1991, FDA informally released an early draft document
called ``Drug Company Supported Activities In Scientific or Educational
Contexts: Draft Concept Paper'' (hereinafter referred to as the draft
concept paper). The draft attempted to clarify FDA's position on
industry-supported scientific and educational activities. Certain
elements of the draft concept paper met some resistance from the
regulated industry, health care professional organizations, and
academic communities. With substantial input from these and other
interested parties, FDA developed the draft policy statement which was
published in the Federal Register on November 27, 1992, for public
comment, and which is now one of the subjects of the WLF Petition. The
draft policy statement is part of an effort to produce a policy
statement that reasonably accommodates the need for industry-supported
scientific and educational activities and the need to regulate industry
labeling and advertising in accordance with the act and the Public
Health Service Act. (See Draft Policy Statement on Industry-Supported
Scientific and Educational Activities at 57 FR 56412.) The draft policy
statement distinguishes between company-supported scientific and
educational activities that are independent of the influence of the
supporting company and those that are not. The content of independent
activities would not be regulated by FDA. The purpose of the draft
policy statement is to clarify this distinction.
The draft policy statement focuses largely on the relationship
between the supporting company and the independent provider responsible
for developing the activity in which information is disseminated. The
agency generally seeks to determine whether the activity is designed to
be a promotional vehicle for the supporting company's products or an
independent educational program. The draft policy statement recommends
that the supporting company enter into a written agreement with the
provider, making clear that the funded event is not to be a promotional
program for the supporting company, but rather is intended to be an
independent scientific or educational activity, controlled in content
and format by the provider and characterized by balance, objectivity,
scientific rigor, and appropriate disclosure of financial support or
conflicts of interest. The draft policy statement states, in part,
that:
[i]f the company abides by such a written agreement and does not
otherwise circumvent its purpose, the agency does not intend to
regulate the activity under the labeling and advertising provisions
of the act, nor under the reporting requirements related to labeling
or as advertisements.
(57 FR 56413.)
Under the draft policy statement, companies could provide financial,
logistical, and technical support for the program without being held
responsible for the program's content for regulatory purposes.
In preparing the draft policy statement, FDA conducted an extensive
outreach effort with scientific and health care professionals,
industry, consumer groups, and other government agencies. FDA proceeded
in this fashion because it recognized the delicate balance required to
accommodate the need for industry-supported scientific and educational
activities and the statutory mandate that products be safe and
effective for their intended uses. In developing the draft policy
statement, senior agency officials met with representatives from the
American Medical Association, the Accreditation Council for Continuing
Medical Education, the Pharmaceutical Manufacturers Association (now
called the Pharmaceutical Research & Manufacturers of America), the
Association of American Medical Colleges, the Health Industry
Manufacturers' Association, the Pharmaceutical Advertising Council, the
American Osteopathic Association, the American Council on
Pharmaceutical Education, and others.
Written comments submitted to the agency after publication of the
draft policy statement were predominantly supportive. Those supporting
the draft policy statement included, among others, the American Medical
Association, the Pharmaceutical Manufacturers Association, the American
Dental Association, the Accreditation Council for Continuing Medical
Education, the American Nurses Association, the American Academy of
Family Physicians, the University of Arizona Health Sciences Center,
the University of Kentucky, the MOET Institute, and the American
Association of Dental Schools.
Most comments supported the draft policy statement and sought only
minor changes or clarifications. Some comments said that the draft
policy statement was not sufficiently restrictive. One comment said
that the draft policy statement ``represents a cave-in to drug
industry/organized medicine pressures.'' Other comments argued that the
policy exceeded FDA's authority under the act or unjustifiably expanded
FDA's legal authority. Some comments claimed FDA's authority in this
area is limited by the First Amendment's protections afforded to
commercial speech or that the draft policy statement restricts a
company's ability to engage in free scientific exchange. Several
comments sought clarification of the draft policy statement's
application beyond live presentations. Certain comments requested that
the draft policy statement exempt written or other enduring materials
from its scope.
In addition to dissemination through live, oral, independent and
nonpromotional educational activities, such as certain symposia,
information on unapproved uses may be disseminated through the
submission of original research to peer-reviewed publications. The
agency has recognized the need among health care professionals for peer
review and dissemination of the latest significant scientific data and
information on drugs and devices in scientific journals. The agency has
thus followed a course under which it may refrain from regulating the
dissemination of information on unapproved uses if the dissemination
involves submission of original research to peer-reviewed journals.
Under current FDA policy, companies may also disseminate
information on unapproved uses in response to unsolicited requests for
scientific information from health care professionals. Scientific
departments within regulated companies generally maintain a large body
of information on their products. When health care professionals
request such information, companies can provide responsive,
nonpromotional, balanced, scientific information, which may include
information on unapproved uses, without subjecting their products to
regulation based on the information. This policy permits companies to
inform health care professionals about the general body of information
available from the company.
Companies may also disseminate independently prepared educational
materials that contain product information. As discussed above, the
agency's general exercise of regulatory authority over company
dissemination of books and similar materials containing product
information is well established in the case law. However, agency policy
is to permit dissemination of materials that are independently
prepared, are prepared solely for educational use, are in the form of
balanced educational material, are not promotional in nature, cover a
number of different products, and are not associated in any way with a
promotional campaign for a specific product.
Although recognized medical textbooks have been disseminated by
companies under this policy, dissemination of materials that are not
recognized by health care professionals or are not independently
prepared may lead to agency regulation. Thus, as in the matter raised
by the petitioner involving ``edited'' versions of a recognized
textbook, the agency has informed companies that their products may be
subject to regulation based on the dissemination of books that are
designed or edited by or for the company (so-called ``custom''
textbooks).
FDA has met with the American Medical Writers Association and the
American Medical Publishers regarding FDA's development of a policy
clarification that specifically addresses ``enduring materials.'' (The
term ``enduring materials'' refers to items such as books, reprints of
articles, and other printed material, as well as programmed course
materials and electronic or recorded material such as computer disks
and videotape.) These groups voiced concern that application of the
draft policy statement to enduring materials would impede their
distribution and the free flow of information. FDA reiterates that it
does not wish to regulate either oral presentations or enduring
materials that are independent and nonpromotional in nature.
FDA has also taken steps to obtain more information on unapproved
uses of approved drug products to facilitate approval of important
unapproved uses that are supported by adequate data. In April 1993, the
agency invited several organizations to identify prevalent unapproved
uses that have therapeutic significance, and that may be supported or
partially supported by published or unpublished clinical data. The
agency indicated that it would encourage manufacturers of the
identified products to submit supplemental applications for those uses.
FDA received over 40 comments and is presently reviewing the
information that it has received.
III. Risks Associated With Unregulated Promotion of Unapproved Uses
Although agency policy has allowed companies several avenues for
disseminating scientific information concerning unapproved uses of
their products, FDA has not abandoned its general position prohibiting
the promotion of unapproved uses. The agency has seen numerous examples
of risks associated with the promotion of unapproved uses in a variety
of contexts.
A. Post-Infarction Anti-Arrhythmic Agents
It is known that patients after an acute myocardial infarction
(AMI, or heart attack) who have a high rate of ventricular premature
beats (VPB's) have a higher mortality, especially sudden death, over
the year following the heart attack, than patients with fewer VPB's.
There are, moreover, plausible relationships between ventricular
premature beats and death; e.g., a ventricular premature beat at the
wrong time can trigger ventricular tachycardia (VT), a poorly
functional rhythm that tends to degenerate ventricular fibrillation,
which is always fatal if not reversed. Still, regardless of whether the
relationships are plausible, the question is whether lowering the rate
of ventricular premature beats will, in fact, lead to fewer deaths. FDA
has never accepted decreased rate of ventricular premature beats as a
surrogate for improved survival. In fact, labeling of anti-arrhythmics
in the late 1970's and 1980's began to emphasize that information on
post-AMI use was not available and that there was no evidence in any
situation that anti-arrhythmics improved survival. No sponsor ever
asked for a survival claim, but many practitioners continued to use
anti-arrhythmics because they had the impression (which was
unsubstantiated) that survival would be favorably affected by VPB
suppression.
Early attempts in controlled studies to see whether post-AMI anti-
arrhythmic therapy improved survival showed no benefit and tended to
show an adverse effect of the treatment, but the studies were flawed,
mainly because they did not choose a population with enough VPB's to
benefit. The Cardiac Arrhythmia Suppression Trial (CAST) was an attempt
to get a definitive answer by selecting patients with high VPB rates,
showing that a drug suppressed VPB's, and then randomizing the patients
to either that drug or placebo to examine survival. The initial drug
screening period also allowed exclusion of patients whose rhythm was
made worse by the drug (pro-arrhythmic effect), a recognized potential
problem with these drugs.
This trial showed a highly unexpected result. Rather than helping
patients, the drugs studied (flecainide and encainide) caused a 2.5-
fold increase in mortality compared to placebo. A second part of the
trial also showed an adverse morbidity effect of moricizine, another
anti-arrhythmic agent. Meta-analysis of studies of anti-arrhythmic
drugs in the post-AMI setting also show adverse trends. There is no
anti-arrhythmic agent, except beta blockers, that has had a favorable
effect on post-AMI survival. Indeed, when these agents have been
properly studied in the post-AMI setting, they have taken, not saved,
lives.
Despite the absence of evidence showing the value of post-AMI VPB
suppression, use of anti-arrhythmic agents for that unapproved
indication was substantial even though drug companies could not legally
promote antiarrhythmic drugs for the unapproved use. Given the greater
mortality in those patients who received the drug, this was an
imprudent claim, but it reflects the potential power of plausible, but
under-documented claims in difficult situations, e.g., where there is
no good treatment for a condition.
B. Post-Infarction Calcium-Channel Blockers
Calcium-channel blockers are effective anti-anginal drugs that are
generally well tolerated. Despite animal data that suggest potential
benefit during and post-infarction, many studies of post-AMI calcium-
channel blocker use have failed to show benefits, and some studies
suggest that they may cause harm, particularly in patients with poor
heart function. There is, therefore, no basis for recommending calcium-
channel blockers for routine post-infarction use. In contrast, several
beta-blockers (such as propranolol, timolol, metoprolol, and atenolol)
have unquestionably been shown to improve survival when given
prophylactically to people who have had an AMI. Use of beta-blockers
and calcium-channel blockers together can lead to problems, and,
especially in patients with poor heart function, the combination could
worsen the patient's condition. Physicians are aware of this and tend
not to use the drugs together although there are many exceptions to
this. To the extent, however, that physicians perceive calcium-channel
blockers as a substitute for beta-blockers to reduce post-AMI morbidity
and leave patients off beta-blockers, patients would be denied the
benefits of the beta-blocker. On average, beta-blockers produce an
approximately 25 percent reduction in annual mortality.
In the past, several manufacturers of calcium-channel blockers
attempted to encourage their use in post-AMI situations, and the agency
successfully rejected these attempts. Extensive promotion of calcium-
channel blocker's for post-AMI use could have been extremely damaging
because the use of calcium-channel blocker's in the population of post-
AMI patients, or segments of that population, appears to be harmful.
More importantly, however, increased use of calcium-channel blocker's
due to the mistaken impression that they have the same effect as beta-
blockers for post-AMI use would have inevitably decreased use of beta-
blockers for this purpose and had a very substantial adverse effect on
post-AMI survival. Given the many patients who sustain an AMI each
year, the loss of life would surely be in the thousands. In this
instance, promotion of an unapproved use would have been lethal.
C. Botulinum Toxin Type A and Cosmetic Use
``BOTOX'' (botulinum Toxin Type A) is a licensed biologic product
for use in the treatment of ``strabismus and blepharospasm associated
with dystonia.'' Currently, these are the only approved indications for
use of this very deadly botulinum toxin. Nevertheless, a patient
information/education bulletin announced new therapies and treatments
using BOTOX strictly for cosmetic purposes. The bulletin claimed, ``NEW
WRINKLE REMEDY * * * SAFE * * * SIDE EFFECTS * * * ARE MINIMAL * * *
.'' This promotion of an unapproved use is an egregious example of
promoting a potentially toxic biologic for cosmetic purposes.
D. Unapproved Uses of Approved Devices
Unnecessary risks can also result from the promotion of unapproved
uses of approved medical devices. For example, one manufacturer's
promotion of such unapproved uses encouraged physicians to extend the
use of the device beyond that which has been proven to be safe and
effective. Other promotions of unapproved uses for approved medical
devices have involved claims for specific diseases or conditions that
go beyond the general claims that FDA cleared or approved. Under the
act, manufacturers must obtain new marketing approvals or clearances
when they promote an approved or cleared device for a new intended use.
Since the public controversy surrounding silicone gel breast
implants, some entrepreneurs have promoted various devices, such as a
``breast coil,'' as effective in detecting leakage of the inner gel
component of the implant to bodily tissues. In addition, some in vitro
diagnostic tests, involving the examination of blood and serum samples,
have been illegally promoted as capable of detecting silicone gel
migration. To date, no evidence has been presented to validate the
efficacy of either of these products for this unapproved use. The
unapproved use of these devices may result in a misdiagnosis of leaking
breast implants, thereby leading to unwarranted surgery to remove the
implant.
Left unchecked, the promotion of unapproved uses not only can
expose patients to unnecessary risks, but also has the potential to
undermine the product approval process. If a manufacturer were free to
promote its product for any use, the manufacturer would have little or
no incentive to conduct the necessary clinical trials to demonstrate
that the product is safe and effective for its intended uses. As a
result, consumers would be exposed to products whose safety and
effectiveness for the unapproved uses are unknown. In addition,
consumers and health care professionals may avoid or delay using known,
effective therapies or products as a result of the attention given to
unapproved uses. Moreover, distinctions between approved and
investigational products would also be blurred, and the protections
associated with the use of investigational products (such as obtaining
informed consent from research subjects and institutional review board
approval to ensure that the rights and welfare of research subjects are
protected) would be easily circumvented.
IV. Striking the Proper Balance: Issues Presented for Comment
Striking the proper balance between the need to regulate the
promotion of unapproved uses for drugs and devices and the need for
reliable scientific data and information on unapproved uses of approved
products has long been a difficult and controversial challenge for the
agency. FDA has given serious consideration to these issues over the
years and has worked with health professional organizations and other
outside parties to develop policies that facilitate company-supported
dissemination of reliable scientific information in a manner that is
consistent with the statutory mandate that products be safe and
effective for their intended uses. Nonetheless, the pending WLF
petition raises issues that merit consideration.
FDA's policies allow for industry-supported scientific and
educational activities and free exchange of information in a manner
consistent with the statutory and regulatory goals. Because drugs and
devices are regulated based on their ``intended use'' (as previously
discussed), the agency's policies may have an unavoidable effect on the
dissemination of information regarding unapproved uses for approved
products. However, FDA emphasizes that these policies are narrowly
drawn and are intended to further describe FDA's regulation of drugs
and devices (not speech), to ensure that sponsors demonstrate that
their drugs or devices are safe and effective for their intended uses,
and to protect consumers from the risks associated with the unapproved
use of drugs and devices whose safety and efficacy for the unapproved
use have not been established. However, the WLF citizen petition
asserts that the draft policy statement, and FDA's regulation of the
promotion of unapproved uses generally, interfere with the First
Amendment rights of physicians and consumers to receive information
regarding unapproved uses. Consequently, FDA invites comments on the
WLF citizen petition and on the following questions:
1. FDA has long recognized that physicians and other health care
professionals may prescribe approved therapies for unapproved uses.
FDA's experience, as previously described, demonstrates that promotion
of unapproved uses may subject patients to serious and unnecessary
risks and may cause health care professionals to refrain from using
other products that may represent first-line therapy or present less
risk. Given the current amount of information available to health care
professionals, what are the added benefits, if any, of allowing
manufacturers to promote unapproved uses of approved products to health
care professionals? What are the additional risks, if any?
2. The WLF petition argues that the draft policy statement and
FDA's regulation of the promotion of unapproved uses are not authorized
by the act, violate the First Amendment, and prevent health care
professionals from providing ``the best possible medical care.'' The
agency believes that the draft policy statement and FDA's regulation of
the promotion of unapproved uses are consistent with its authority and
responsibilities under the act, do not violate the First Amendment,
facilitate dissemination of accurate product information, and as noted
above, prevent patients from being exposed to products whose safety and
efficacy for an unapproved use have not been demonstrated. Given these
different considerations, the amount of scientific and educational
information available to health care professionals, and the sources of
information (other than industry-supported activities) available to
health care professionals, does the agency's implementation of its
statutory authority significantly limit health care professionals'
access to current, scientifically valid information regarding
unapproved uses for approved products? Does the draft policy statement
restrict or facilitate access by health care professionals to current,
scientifically valid information regarding unapproved uses for approved
products? How might the involvement of device or pharmaceutical
manufacturers in the preparation or dissemination of information on
unapproved uses affect that information?
3. The draft policy statement acknowledges that discussion of
unapproved uses can be an important component of scientific and
educational activities. The draft policy statement does not prohibit
such discussion, but encourages disclosure of the fact that a product
is not approved in the United States for the use under discussion. In
addition, company-supported activities that do not relate to the
company's product, a competing product, or suggest a use for the
company's product would not be regulated as promotional activities
under the draft policy statement. Given its narrow scope, how might the
draft policy statement preclude health care professionals and patients
from receiving important scientific information regarding unapproved
uses for approved products?
4. The WLF petition suggests that FDA adopt a formal policy stating
that FDA will not interfere in company-supported, ``non-labeling
activities'' whose effect is to promote--through the dissemination of
``truthful'' medical informatio--unapproved uses of approved drugs and
medical devices. However, FDA's broad experience reviewing promotional
materials and scientific data suggests that determining whether
information is ``truthful'' may depend on a variety of factors,
including time, context, publication bias, lack of stringent review
before publication, whether a published article appeared in a journal
or in a purchased ``supplement'' to a journal, etc. For example, a
preliminary study may suggest a result that appears ``truthful'' at the
time the preliminary study is first announced, but subsequent studies
may fail to reproduce those results, disprove the preliminary result,
or even show that the preliminary study was flawed. Given the wide
variety of factors, how should one determine whether the information in
question is, indeed, ``truthful?''
