2322 Rayburn House Office
INTRODUCTION
Mr. Chairman and
Members of the Subcommittee, I am Dr. Janet Woodcock, Director of the Center
for Drug Evaluation and Research (CDER), Food and Drug Administration (FDA or
the Agency). I am here today to update
you on three important areas that CDER is continuing to work on:
(1) FDA's implementation of
provisions of the Drug Price Competition and Patent Term Restoration Act of
1984 (Hatch-Waxman Amendments) that govern the generic drug approval process.
(2)
The promotion that manufacturers of prescription drugs (product
sponsors) direct toward consumers and patients. This is referred to as "direct-to-consumer" promotion
or DTC.
(3)
The mechanism for reclassification of drugs from prescription to
over-the-counter (OTC) status, namely, the request for the OTC switch by a
third party, a novel situation FDA is presently facing.
I. GENERIC DRUGS
FDA's implementation
of provisions of the Drug Price Competition and Patent Term Restoration Act of
1984 (Hatch-Waxman Amendments) govern the generic drug approval process. These provisions give 180 days of marketing
exclusivity to certain generic drug applicants. The 180-day generic drug exclusivity provision is one component
of the complex patent listing and certification process, which also provides
for a 30-month stay on generic drug approvals while certain patent infringement
issues are litigated.
The Hatch-Waxman Amendments are intended to balance two important
public policy goals. First, drug
manufacturers need meaningful market protection incentives to encourage the
development of valuable new drugs.
Second, once the statutory patent protection and marketing exclusivity
for these new drugs has expired, the public benefits from the rapid
availability of lower priced generic versions of the innovator drug.
STATUTORY PROVISIONS
The Hatch-Waxman
Amendments amended the Federal Food, Drug, and Cosmetic (FD&C) Act and
created section 505(j). Section 505(j)
established the abbreviated new drug application (ANDA) approval process, which
permits generic versions of previously approved innovator drugs to be approved
without submission of a full new drug application (NDA). An ANDA refers to a previously approved NDA
(the "listed drug") and relies upon the Agency's finding of safety
and effectiveness for that drug product.
The timing of an ANDA approval depends in part on patent protections
for the innovator drug. Innovator drug applicants must include in an NDA
information about patents for the drug product that is the subject of the
NDA. FDA publishes patent information
on approved drug products in the Agency's publication "Approved Drug Products
with Therapeutic Equivalence Evaluations" (the Orange Book) (described in
more detail below). The FD&C Act
requires that an ANDA contain a certification for each patent listed in the
Orange Book for the innovator drug.
This certification must state one of the following:
(I) that the required patent
information relating to such patent has not been filed;
(II) that such patent has
expired;
(III) that the patent will expire on a particular date; or
(IV) that such patent is invalid or will not be infringed by the drug,
for which approval is
being sought.
A certification under paragraph I or II permits the ANDA to be approved
immediately, if it is otherwise eligible.
A certification under paragraph III indicates that the ANDA may be
approved on the patent expiration date.
A paragraph IV certification begins a process, in which the question of
whether the listed patent is valid or will be infringed by the proposed generic
product may be answered by the courts prior to the expiration of the
patent. The ANDA applicant who files a
paragraph IV certification to a listed patent must notify the patent owner and
the NDA holder for the listed drug that it has filed an ANDA containing a
patent challenge. The notice must
include a detailed statement of the factual and legal basis for the ANDA
applicant's opinion that the patent is not valid or will not be infringed. The submission of an ANDA for a drug
product claimed in a patent is an infringing act if the generic product is
intended to be marketed before expiration of the patent, and therefore, the
ANDA applicant who submits an application containing a paragraph IV
certification may be sued for patent infringement. If the NDA sponsor or patent owner files a patent infringement
suit against the ANDA applicant within 45 days of the receipt of notice, FDA
may not give final approval to the ANDA for at least 30 months from the date of
the notice. This 30-month stay will
apply unless the court reaches a decision earlier in the patent infringement
case or otherwise orders a longer or shorter period for the stay.
The statute provides an incentive of 180 days of market exclusivity to
the "first" generic applicant who challenges a listed patent by
filing a paragraph IV certification and running the risk of having to defend a
patent infringement suit. The statute
provides that the first applicant to file a substantially complete ANDA
containing a paragraph IV certification to a listed patent will be eligible for
a 180-day period of exclusivity beginning either from the date it begins
commercial marketing of the generic drug product, or from the date of a court
decision finding the patent invalid, unenforceable or not infringed, whichever
is first. These two events - first
commercial marketing and a court decision favorable to the generic - are often
called "triggering" events, because under the statute they can
trigger the beginning of the 180-day exclusivity period.
In some circumstances, an applicant who obtains 180-day exclusivity may
be the sole marketer of a generic competitor to the innovator product for 180
days. But 180-day exclusivity can
begin to run - with a court decision - even before an applicant has received
approval for its ANDA. In that case,
some, or all, of the 180-day period could expire without the ANDA applicant
marketing its generic drug.
Conversely, if there is no court decision and the first applicant does
not begin commercial marketing of the generic drug, there may be prolonged or
indefinite delays in the beginning of the first applicant's 180-day exclusivity
period. Approval of an ANDA has no
effect on exclusivity, except if the sponsor begins to market the approved
generic drug. Until an eligible ANDA
applicant's 180-day exclusivity period has expired, FDA cannot approve
subsequently submitted ANDAs for the same drug, even if the later ANDAs are
otherwise ready for approval and the sponsors are willing to immediately begin
marketing. Therefore, an ANDA applicant
who is eligible for exclusivity is often in the position to delay all generic
competition for the innovator product.
Only an application containing a paragraph IV certification may be
eligible for exclusivity. If an
applicant changes from a paragraph IV certification to a paragraph III
certification, for example upon losing its patent infringement litigation, the
ANDA will no longer be eligible for exclusivity.
COURT DECISIONS AND FDA ACTIONS
This 180-day exclusivity provision has been the subject of considerable
litigation and administrative review in recent years, as the courts, industry,
and FDA have sought to interpret it in a way that is consistent both with the
statutory text and with the legislative goals underlying the Hatch-Waxman
Amendments. A series of Federal court
decisions beginning with the 1998 Mova
case describe acceptable interpretations of the 180-day exclusivity provision,
identify potential problems in implementing the statute, and establish certain
principles to be used by the Agency in interpreting the statute.
In light of the court decisions finding certain FDA regulations
inconsistent with the statute, the Agency proposed new regulations in August
1999 to implement the 180-day exclusivity.
Since then many comments have been submitted and there have been
additional court decisions further interpreting the 180-day exclusivity
provision and complicating the regulatory landscape. The Agency has not yet published a final rule on 180-day
exclusivity. As described in a June
1998 guidance for industry, until new regulations are in place, FDA is
addressing on a case-by-case basis those 180-day exclusivity issues not
addressed by the existing regulations.
One of the most fundamental changes to the 180-day exclusivity program
that has resulted from the legal challenges to FDA's regulations is the
determination by the courts of the meaning of the phrase "court
decision." The courts have
determined that the "court decision" that can begin the running of
the 180-day exclusivity period may be the decision of the district court, if it
finds that the patent at issue is invalid, unenforceable, or will not be
infringed by the generic drug product.
FDA had interpreted the "court decision" that could begin the
running of 180-day exclusivity (and the approval of the ANDA) as the final decision
of a court from which no appeal can be or has been taken - generally a decision
of the Federal Circuit. FDA's
interpretation had meant that an ANDA applicant could wait until the appeals
court had finally resolved the patent infringement or validity question before
beginning the marketing of the generic drug.
FDA had taken this position so that the generic manufacturer would not
have to run the risk of being subject to potential treble damages for marketing
the drug, if the appeals court ruled in favor of the patent holder. The current interpretation means that if
the 180-day exclusivity is triggered by a decision favorable to the ANDA
applicant in the district court, the ANDA sponsor who wishes to market during
that exclusivity period now may run the risk of treble damages if the district
court decision is reversed on appeal to the Federal Circuit. As a practical matter, it means that many
generic applicants may choose not to market the generic and thus the 180-day
exclusivity period could run during the pendency of an appeal.
In one of the cases rejecting FDA's interpretation of the "court
decision" language in the statute, the court determined that the applicant
who relied in good faith on FDA's interpretation of the 180-day exclusivity provision
should not be punished by losing its exclusivity. The court, therefore, refused to order FDA to begin the running
of 180-day exclusivity upon the decision of the district court in the patent
litigation at issue. FDA has taken a
similar approach in implementing the courts' decisions: the new "court decision"
definition will apply only for those drugs for which the first ANDA was
submitted subsequent to March 30, 2000.
In adopting this course, a primary concern for the Agency was to
identify an approach that would minimize further disruption and provide
regulated industry with reasonable guidance for making future business
decisions.
To advise the public and industry of this position, FDA published a
Guidance for Industry in March 2000.
FDA intends to incorporate the courts' interpretation of the "court
decision" trigger for 180-day exclusivity into the final rule implementing
the changes in 180‑day exclusivity.
ORANGE BOOK LISTINGS
There have been concerns expressed over FDA's role in the listing of
patents in the Orange Book, which can have an impact on generic drug approvals
by delaying approval and 180-day exclusivity.
Under the FD&C Act, pharmaceutical companies seeking to market
innovator drugs must submit, as part of an NDA or supplement, information on
any patent that 1) claims the pending or approved drug or a method of using the
approved drug, and 2) for which a claim of patent infringement could reasonably
be asserted against an unauthorized party.
Patents that may be submitted are drug substance (active ingredient)
patents, drug product (formulation and composition) patents, and method of use
patents. Process (or manufacturing)
patents may not be submitted to FDA.
When an NDA applicant submits a patent covering the formulation,
composition, or method of using an approved drug, the applicant must also
submit a signed declaration stating that the patent covers the formulation,
composition, or use of the approved product.
The required text of the declaration is described in FDA's
regulations. FDA publishes patent
information on approved drug products in the Orange Book.
The process of patent certification, notice to the NDA holder and
patent owner, a 45-day waiting period, possible patent infringement litigation
and the statutory 30-month stay mean there is the possibility of a considerable
delay in the approval of ANDAs as a result of new patent listings. Therefore, these listings are often closely
scrutinized by ANDA applicants. FDA
regulations provide that, in the event of a dispute as to the accuracy or
relevance of patent information submitted to and subsequently listed by FDA, an
ANDA applicant must provide written notification of the grounds for dispute to
the Agency. FDA then requests the NDA
holder to confirm the correctness of the patent information and listing. Unless the patent information is withdrawn
or amended by the NDA holder, FDA will not change the patent information listed
in the Orange Book. If a patent is
listed in the Orange Book, an applicant seeking approval for an ANDA must
submit a certification to the patent.
Even an applicant whose ANDA is pending when additional patents are
submitted by the sponsor must certify to the new patents, unless the additional
patents are submitted by the patent holder more than 30 days after issuance by
the U.S. Patent and Trademark Office.
FDA does not undertake an independent review of the patents submitted
by the NDA sponsor. FDA does not assess
whether a submitted patent claims an approved drug and whether a claim of
patent infringement could reasonably be made against an unauthorized use of the
patented drug. FDA has implemented the
statutory patent listing provisions by informing interested parties what patent
information is to be submitted, who must submit the information, and when and
where to submit the information. As
the Agency has stated, since the implementation of the 1984 Hatch-Waxman
Amendments began, FDA has no expertise or resources with which to resolve
complex questions of patent coverage, and thus the Agency's role in the
patent-listing process is ministerial.
The statute requires FDA to publish patent information upon approval of
the NDA. The Agency relies on the NDA
holder or patent owner's signed declaration stating that the patent covers an
approved drug product's formulation, composition or use. Generic and innovator firms may resolve any
disputes concerning patents in private litigation. As noted above, if the generic applicant files a paragraph IV
certification and is sued for patent infringement within 45 days, there is an
automatic stay of 30 months, substantially delaying the approval of the generic
drug and, thus, the availability of lower cost generic drug products.
CONCLUSION
FDA continues to implement the Hatch-Waxman Amendments exclusivity
provisions in the best manner possible given the text of the legislation, the
history of the legislation and the numerous court challenges. Again, as previously noted, FDA has tried
to balance innovation in drug development and expediting the approval of
lower-cost generic drugs.
II. DIRECT
TO CONSUMER ADVERTISING
STATUTORY AND
REGULATORY AUTHORITY
The promotion that
manufacturers of prescription drugs (product sponsors) direct toward consumers
and patients is referred to as "direct-to-consumer" promotion or
DTC. Such promotion uses multiple
avenues for reaching lay audiences, including, but not limited to: television
and radio advertisements, print advertisements, telephone advertisements,
direct mail, videotapes and brochures.
It is important to understand the scope of FDA's authority in this
area. It is also important to
understand the different types of advertisements that are directed toward
consumer audiences.
The FD&C Act and regulations do not
distinguish between professional and consumer audiences. Section 502(n) of the FD&C Act
specifies that prescription drug advertisements must contain "a true
statement of . . . information in brief summary relating to side effects,
contraindications, and effectiveness" of the advertised product. The implementing regulations (Title 21, Code
of Federal Regulations [CFR] Section 202.1), originally issued in the
1960s, specify, among other things, that prescription drug advertisements
cannot be false or misleading, cannot omit material facts, and must present a
fair balance between effectiveness and risk information. Further, for print advertisements, the
regulations specify that every risk addressed in the product's approved
labeling must also be disclosed in the advertisements.
For broadcast advertisements, however, the regulations require ads to
disclose the most significant risks that appear in the labeling. The regulations further require that the
advertisement either contain a summary of "all necessary information related
to side effects and contraindications" or convenient access must be
provided to the product's FDA- approved labeling and the risk information it
contains.
Finally, the FD&C Act specifically prohibits FDA from requiring
prior approval of prescription drug advertisements, except under extraordinary
circumstances. Also, the advertising
provisions of the FD&C Act do not address the issue of drug product cost.
TYPES
OF ADVERTISEMENTS
There are three different types of ads that product sponsors use to communicate
with consumers:
"product-claim" advertisements, "help-seeking"
advertisements, and "reminder" advertisements. Advertisements that include both a product's
name and its use, or that make any claims or representations about a
prescription drug, are known as "product-claim" advertisements. These ads must include a "fair
balance" of risks and benefits.
In addition, they must provide all risk information included in the
product's FDA-approved labeling or, for broadcast advertisements, provide convenient
access to this information. In our
regulations, the phrase "adequate provision" is used to identify the
convenient access option. Unlike the
"product claim" ads, "help-seeking" advertisements and
"reminder" ads need not include any risk information.
A "help-seeking" advertisement discusses a disease or
condition and advises the audience to "see your doctor" for possible
treatments. Because no drug product is
mentioned or implied, this type of ad is not considered to be a drug ad and FDA
does not regulate it.
The second type of advertisement that does not need to include risk
information is called a "reminder" advertisement. The regulations specifically exempt this
type of ad from the risk disclosure requirements. Like "help-seeking" ads, the "reminder" ad
is limited, although in a different way from "help-seeking" ads. "Reminder" ads are allowed to
disclose the name of the product and certain specific descriptive (e.g., dosage
form) or cost information, but they are not allowed to give the product's
indication or dosage recommendations, or to make any claims or representations
about the product. The exemption for
"reminder" ads was included in FDA's regulations for promotions
directed toward health care professionals, who presumably knew both the name of
a product and its use.
"Reminder" ads serve to remind health care professionals of a
product's availability. They
specifically are not allowed for products with serious warnings (called
"black box" warnings) in their labeling.
EVOLUTION
OF DTC PROMOTION
Prior to the early 1980s, prescription products were not promoted
directly to consumers and patients.
Instead, product sponsors often produced materials that were given to
health care professionals to pass on to patients if they thought this would be
appropriate for particular patients.
In the early 1980s, a few companies started advertising products
directly to patient audiences (specifically, older people concerned about
pneumonia and people taking prescription ibuprofen to treat arthritis
pain). As a result of questions and
concerns about promotion directed toward non-health care professionals, in 1983
FDA requested that sponsors suspend DTC ads to give the Agency time to study the
issue.
The industry complied with this request, and during the ensuing
moratorium FDA conducted research and sponsored a series of public
meetings. In 1984, the University of
Illinois and Stanford Research Institute jointly sponsored a symposium to discuss
consumer-directed prescription drug advertising from a broad research and
policy perspective. On September 9,
1985, FDA withdrew the moratorium in a Federal Register (FR)
Notice (50 FR 36677), which stated that the "current regulations governing
prescription drug advertising provide sufficient safeguards to protect
consumers."
During the early 1990's, product sponsors increasingly used consumer
magazines to advertise their products.
These ads typically included a promotional message together with the
"brief summary" of adverse effects, similar to that used in physician
directed ads. The "brief
summary" statement, which frequently appears in small print, is not very
consumer friendly. In the 1990s,
product sponsors also started using television advertisements in a limited
fashion. Television advertisements were
limited because FDA and industry did not believe that it was feasible to
disseminate the product's approved labeling in connection with the ad. The extensive disclosure needed to fulfill
this requirement essentially precluded the airing of such ads. For example, one way to satisfy this
requirement would be to scroll the "brief summary," which would take
a minute or more even at a barely readable scrolling rate. The industry, therefore, resorted to
television ads that did not require risk disclosure.
By the mid-1990s, product sponsors started placing "reminder"
ads on television. Because these ads
only mentioned the name of the drug, however, they were extremely confusing to
consumers, who, unlike health care professionals, were not knowledgeable about
the name and the use for these products.
In response to increasing consumer demand for information, FDA began to
consider whether broadcast advertisements could be constructed to ensure access
to product labeling, the only alternative to including all of an advertised
product's risk information. FDA
considered suggestions about providing access to multiple sources of product
labeling as a means of satisfying the requirement that consumers have
convenient access to FDA-approved labeling when manufacturers broadcast a
"product-claim" advertisement.
In August 1997, FDA issued a draft guidance entitled: "Guidance for Industry: Consumer-Directed Broadcast
Advertisements" that clarified the Agency's interpretation of the existing
regulations. The Guidance described an
approach for ensuring that audiences exposed to prescription drug
advertisements on television and radio have convenient access to the advertised
product's approved labeling. The
proposed mechanism consisted of reference in the broadcast advertisement to
four sources of labeling information: a
toll-free telephone number, a website address, a concurrently running print
advertisement, and health care professionals.
Following a comment period, and detailed review and consideration of the
comments, FDA made only minor changes to the draft guidance, and issued it in
final form in August 1999 (64 FR 43197, also found at http://www.fda.gov/cder/guidance/1804fnl.htm). In announcing the final guidance, FDA
advised that the Agency intended to evaluate the impact of the guidance, and of
DTC promotion in general, on the public health, within two years of finalizing
the guidance.
STAKEHOLDER PERSPECTIVES
A number of stakeholder groups have expressed strong interest in DTC
promotion. Those that are positive
about DTC promotion assert that this practice will:
·
Improve consumers' knowledge of drugs and
drug availability.
·
Encourage consumers to talk with their
health care providers about their health problems.
·
Allow consumers and patients to have a
greater role in decisions about their own health care
that they say they
desire.
·
Improve communication between patients
and their physicians.
·
Improve appropriate prescribing by
allowing physicians to get more information about their
patients from their
patients.
·
Lower the cost of prescription
drugs. Not all stakeholders are
positive about DTC
promotion. Opponents assert that DTC advertising will:
·
Confuse consumers about drugs.
·
Make it appear that prescription drugs
are safer than they are.
·
Interfere with the patient-physician
relationship because patients will insist that their
physicians prescribe the
advertised products.
·
Increase inappropriate prescribing.
·
Raise the cost of prescription drugs.
Finally, there is a group of stakeholders with a less polarized view of
DTC promotion. They believe that such
promotion has both benefits and risks, but that it should be strictly regulated,
and that, preferably, all DTC materials should be "pre-approved" by
FDA. They often assert that there are
potential public health benefits associated with patients visiting health care
providers about untreated diseases or conditions, particularly those that
appear to be under treated in the population and that are responsible for
long-term harm (for example, high cholesterol, high blood pressure, diabetes
and osteoporosis).
CURRENT
SITUATION
FDA recognizes that drug promotion raises certain issues for health
care professionals and different issues for consumers, in light of differences
in medical and pharmaceutical expertise.
For this reason, FDA has monitored DTC promotion, and especially
broadcast promotion, very closely to help ensure that adequate contextual and
risk information, presented in understandable language, is included to fulfill
the requirement for fair balance and to help the consumer accurately assess
promotional claims and presentations.
Product sponsors of prescription advertisements are required to submit
their promotional materials to FDA around the time these materials are
initially put into public use. FDA
receives approximately 32,000 of these submissions per year, for all types of
promotion, including promotion to health care professionals. Product Sponsors also can submit draft
materials to FDA for review and comment prior to using them. Division of Drug Marketing, Advertising and
Communications (DDMAC) has made it a high priority to provide comments to
product sponsors on voluntarily submitted draft broadcast advertisements within
a reasonable time. In fact, although
it is not required, a majority of product sponsors voluntarily submit their
broadcast advertisements to DDMAC for prior review and comment at some point as
advertising materials are being produced.
Product sponsors may ask for review and comment at the very initial
stages of production (by supplying the words they intend to use along with
rough drawings of their proposed graphics), or at the later stages of final
videotape production. DDMAC only gives
final comments on final videotapes because inappropriate presentations can turn
an otherwise acceptable advertisement into an unacceptable one (for example, by
pacing the risk disclosure too rapidly, including multiple distracting visual
images during the risk disclosure, or including images that overstate the
efficacy of the product beyond what is supported by substantial clinical
evidence).
Since January 1997, sponsors of about 65 prescription drugs have aired
"product-claim" advertisements on television or radio. A small number of prescription biological
products also have been advertised.
Nine products fall into the allergy category (nasal and ocular
anti-histamines, and nasally administered corticosteroids), while another eight
products treat skin or hair-related problems (acne, cold sores, rosacea,
baldness, unwanted facial hair, nail fungus).
More importantly, ten products are designed to treat diseases that are
believed to be under treated, including high cholesterol and heart disease, and
mental health problems like depression.
Five products to treat or prevent osteoporosis or menopausal symptoms
have been advertised. Other advertised
products are approved to treat such conditions or diseases as asthma,
Alzheimer's Disease, arthritis, chronic obstructive pulmonary disease,
diabetes, insomnia, migraine, obesity, overactive bladder, serious heartburn,
smoking cessation, and sexually transmitted diseases. Most of these are serious problems where patients are in the
best position to recognize symptoms.
It is important to note that DDMAC does not know how many different
advertisements have aired in broadcast media for these 65 drugs. There have been multiple campaigns for a
number of the products, including the allergy and high cholesterol
products. In addition, many campaigns
include different length "product-claim" commercials, as well as
multiple short "reminder" commercials. DDMAC does not track the number of different broadcast
advertisements that are submitted.
Further, because "help-seeking" advertisements, if done
properly, are not considered to be drug ads, most product sponsors do not send
them to DDMAC under the submission requirements for prescription drug
promotional materials. Therefore, we have no measure of how many of
these have been in the public domain.
ENFORCEMENT
RELATED TO DTC PROMOTION
Since August 1997, FDA has issued:
·
26 "untitled" (or "Notice
of Violation") letters on "product-claim" broadcast
advertisements. Such letters request
that the violative promotion be stopped immediately. Product sponsors virtually always comply immediately with this
request.
·
3 "warning letters" on
broadcast advertisements. This is a
higher-level enforcement action, and requests that a remedial campaign be
conducted by the company to correct the impressions left by the ad.
·
13 "untitled" letters on
purported "reminder" broadcast advertisements.
·
3 "untitled" letters on
purported "help-seeking" broadcast advertisements.
Most of the violations cited were because the ad overstated or
guaranteed the product's efficacy, expanded the indication or the patient
population approved for treatment, or minimized the risks of the product,
through either inadequate presentation or omission of information.
Since January 1997, the Agency has issued:
·
43 "untitled" letters that
addressed DTC print advertisements or other promotional materials, including
purported "reminder" and "help-seeking" materials.
·
1 "warning letter" that
included a DTC print advertisement as part of an overall misleading
campaign.
Generally, the violations involving print ads making
"product-claim" ads were similar to those cited above. Nearly all "reminder" ad
violations were the result of representations about the product that triggered
the need for full disclosure of benefits and risks. "Help-seeking" ad violations were due to a particular
product being implied in the message.
As noted above, however, FDA cannot determine how many specific
advertisements serve as the denominator for assessing how many have resulted in
enforcement action compared with those that have not.
RESEARCH ON DTC PROMOTION
A number of groups have been conducting research on DTC promotion. Much publicly available research consists
of surveys utilizing samples of consumers or patients to examine attitudes
about DTC promotion and self-reported behaviors related to DTC promotion in the
context of patient-physician visits and use of prescription drugs. The groups sponsoring this research include: Prevention magazine, TIME Inc., the National
Consumers League, and American Association of Retirement People. A few surveys of physicians have been made
partially publicly available. FDA
remains concerned, however, about the representation of the physician
surveys. In 1999, FDA sponsored a
telephone survey that focused on a national probability sample of patients who
had seen a physician for a problem on their own within the three months prior
to the survey. The results of this
patient survey suggested that patients are seeking additional information as a
result of DTC promotions that they have seen.
This information was sought primarily from health care professionals,
and secondarily from reference texts and family. Generally, between 10 and 20 percent of respondents said that
they sought additional information from the sources referenced in broadcast
advertisements - toll-free telephone numbers, web sites, print
advertisements. A major result, and
one that is consistent with results of Prevention's national surveys, is that a
significant minority of respondents said that a DTC ad has caused them to ask a doctor about a
medical condition or illness they had not previously discussed. This could represent a significant and
positive public health benefit, particularly if these patients are talking
about undiagnosed heart disease or other serious disorders.
The survey results also
suggest that DTC advertisements are not significantly increasing visits to a
physician's office. For the most part,
patients said that they had recently visited their doctors for the traditional
reasons: because it was time for a
check-up (53 percent), because they were feeling ill (42 percent), or because
they had had a sudden symptom or illness (41 percent). Only two percent said that they had visited
their doctor because of something they had seen or heard. Of those patients who had a conversation
with their doctor about a prescription drug:
81 percent said that their doctor had welcomed the question, 79 percent
said that their doctor discussed the drug with them, and 71 percent said that
their doctor had reacted as though the conversation was an ordinary part of the
visit. Only four percent said that
their doctor seemed upset or angry when the patient asked about a prescription
drug. According to the patients,
therefore, physicians seem to be reacting well to questions about prescription
drugs. Finally, only 50 percent of
these patients said that their doctor gave them the medication discussed. Thirty-two percent said that the doctor
recommended a different drug.
Twenty-nine percent of the respondents indicated that behavioral or
lifestyle changes were suggested by the doctor. It therefore appears, from FDA's data, that physicians are
comfortable denying prescriptions when the prescription would not be right for
the patient.
A small number of patients
who were denied prescriptions said that their doctors told them why. Reasons included: the drug wasn't right for the patient; the doctor wanted the
patient to take a different drug; the drug had side effects of which the
patient was unaware; the patient did not have the condition treated by the
drug; the patient did not need a prescription drug; the patient could use a
non-prescription drug; and, there was a less expensive drug available.
Patients also were asked
about their attitudes about prescription drug advertisements. Their answers indicated somewhat mixed
feelings. Eighty-six percent agreed
that these ads help make them aware of new drugs, 70 percent agreed that the
ads give enough information to help the patient decide if they should discuss
the product with a doctor, and 62 percent agreed that ads help the patients
have better discussions with their doctors about their health. Only 24 percent agreed that DTC ads make it
seem like a doctor is not needed to decide whether a drug is right for
someone. In contrast, 58 percent
agreed that DTC ads make drugs seem better than they really are, 59 percent
agreed that ads do not give enough information about the advertised product's
risks and negative effects, and 49 percent agreed that these ads do not give
enough information about the benefits and positive effects of the advertised
product.
NEXT STEPS
In issuing both the draft and the final broadcast advertisement
guidance, FDA stated its intent to assess the impact of the guidance, and of
DTC promotion in general, on the public health. FDA is also aware that privately funded research is being planned
to examine the effects of DTC promotion.
At present, FDA is not aware of any evidence that the risks of DTC
promotion outweigh its benefits. FDA

III. PRESCRIPTION DRUG SWITCH TO
OVER-THE-COUNTER
STATUS
The FDA is responsible for the reclassification of many drugs from
prescription to OTC status. These are
often referred to as "switch drugs," and the reclassification process
is referred to as "switching from prescription to OTC." Nearly forty ingredients incorporated into
drug products have been reclassified since 1972 when the OTC drug review began.
Under the FDA's Office of OTC Drug Evaluation, a process was
established for producing a final regulation to set standards for each drug
product-treatment category. Nearly
forty ingredients has been reclassified using this process since 1972 using
this process.
Switches are covered by the prescription
exemption procedures, found in 21 CFR 310.200. Switches can
be initiated by FDA, the sponsor of a new drug application, or by any
interested party. The OTC drug product
can be marketed under a NDA or under the process established by
regulation. The switch may be:
1. A
complete switch whereby all of the indications and dosage forms are switched
from
prescription to OTC status;
2. A
partial switch whereby some of the prescription indications and dose regimens
are
switched to OTC status and the others remain prescription.
Historically, the majority of drugs that have been switched from
prescription-only to OTC marketing were at the initiated by the sponsor. The FD&C Act restricts drugs to
prescription only status if a learned intermediary is required for the proper
use of the drug. As written, the default
assumption of the Act is for drugs to be marketed OTC without a prescription
unless a decision is made that consumers are not able to appropriately diagnose
their condition nor able to correctly choose the remedy and safely use it based
on OTC labeling.
Anyone may submit a citizen petition.
Individuals sometimes submit petitions, but most come from the regulated
industry or consumer groups. For the
first time, a third party has asked the FDA to reclassify a drug through the
citizen petition process. Because the
petition is still under review, we cannot comment on it at this time. FDA may use a wide range of public
procedures (e.g., conferences, meetings, correspondence, hearings) during the
process of evaluating the petition and to assist in the formulation of a final
response.
In the process of
responding to a petition, the Agency creates an administrative record, a
comprehensive documentary foundation for the agency's final decision. The Agency's grant or denial of a petition,
which usually is in the form of a letter to the petitioner, constitutes a final
agency action. The Agency may also
issue a tentative response explaining that the Agency has not yet reached a
final decision on whether to grant or deny the petition. When FDA issues a final decision, however,
it may be appealed through the court system.
As with any petition, FDA is studying the scientific and legal issues
it raises in an effort to make the best science-based decision under the law.
We look forward to the Committee's continued interest in this area and
would be happy to answer any questions.
