FDA USER FEES: ADVANCING PUBLIC HEALTH
THURSDAY, JULY 28, 2011
U.S. Senate,
Committee on Health, Education, Labor, and Pensions,
Washington, DC.
The committee met, pursuant to notice, at 9:50 a.m. in Room
430, Dirksen Senate Office Building, Hon. Tom Harkin, chairman
of the committee, presiding.
Present: Senators Harkin, Mikulski, Murray, Hagan, Merkley,
Franken, Bennet, Enzi, Alexander, Burr, Isakson, and Hatch.
Opening Statement of Senator Harkin
The Chairman. The Committee on Health, Education, Labor,
and Pensions will come to order. We've convened this hearing
today to kick off the FDA user fee reauthorization process. We
will discuss the history and purpose of the user fee agreements
between the FDA and the industries it regulates, and we will
learn more about the importance of user fees to ensuring that
new medical products get to the American patients as quickly
and safely as possible.
Since 1992, the Prescription Drug User Fee Agreement has
paved the way for quicker and more thorough reviews of
applications for prescription drug products. Ten years later,
beginning in 2002, the Medical Device User Fee Agreement has
similarly facilitated getting medical devices onto the market.
Currently, the drug and device user fees collectively make up
34 percent of FDA's overall budget. They are a significant
source of the funds that FDA needs to get its job done.
Both the Prescription Drug User Fee Agreement and the
Medical Device User Fee Agreement expire at the end of the next
fiscal year. Failing to reauthorize them would have significant
consequences for FDA, which would have to let staff go and
substantially slow its approval process; and even more
importantly, failing to pass the reauthorization legislation
would have devastating consequences for the patients, whose
health and lives depend on new medical treatments. We can't let
that happen. For the health of the agency, the medical products
industry and, most importantly, the patients who rely on new
medical technologies, we need to reauthorize the user fee
agreements before they expire.
I know that this legislation is likely to attract attention
from everyone here who is interested in policy related to the
FDA. I have policy priorities of my own, including helping to
ensure the integrity of our global pharmaceutical supply chain
at a time when our drug products and their ingredients are
increasingly being brought to the United States from around the
world.
This fall, we hope and expect to convene hearings to
explore some of these policy issues. Today, however, we begin
the process with a focus on user fees themselves.
We welcome Dr. Peggy Hamburg, the Commissioner of the FDA,
and look forward to her description of the history and
importance of the user fee program, and explanation of the
impact user fees have on FDA's ability to get medical products
to American consumers.
We look forward to hearing Commissioner Hamburg's views on
this important subject, and I look forward to working with my
colleague and Ranking Member, Senator Enzi, to continue the
tradition of bipartisan cooperation on these user fee efforts.
Now I'll yield to Senator Enzi.
Statement of Senator Enzi
Senator Enzi. Thank you, Mr. Chairman, and thank you for
having this hearing.
The Prescription Drug and Medical Device User Fee programs
have been a success, originally decreasing product review
times, stabilizing funding for FDA's Drug and Medical Device
Centers, and decreasing the burden on taxpayers. I do believe,
however, that the FDA can do better. On the metric most
important for patients, the total time to market, FDA's
performance regarding medical devices has declined sharply.
According to a study by Boston Consulting Group, by the
California Health Care Institute, overall 510(k) review times
have increased 43 percent, and PMA review times have increased
by 75 percent over the past 4 years. These findings have been
widely corroborated. Numerous studies have identified serious
problems with the Device Center's performance.
The Device Center's performance is not a partisan issue.
Democrats and Republicans, patient and consumer groups,
industry, academics, and nonprofits alike have all raised
serious concerns about the Device Center's performance. FDA
itself has engaged in extensive self-scrutiny, and the
Institute of Medicine is expected to report on several
controversial problems tomorrow.
In this Congress, I look forward to working with Chairman
Harkin to reauthorize these user fee agreements. We have a
couple of challenges as we try to move this legislation. First
is timing. We plan to front-load as much of the work as
possible to conclude the HELP Committee markup by the spring of
2012. Second, the Federal debt is about $14 trillion and
rising, and FDA is close to a tipping point. In the past few
years, Congress has imposed several challenging new mandates on
the agency. The Government Accountability Office has put FDA on
its high-risk list because the FDA is overwhelmed by its many
diverse public health responsibilities. We need to be practical
and strategic about what FDA can and cannot do.
I do want to salute Commissioner Hamburg for recognizing
and starting to address these strategic challenges, and I'll
have some questions for the record concerning the agency's
recent reorganization.
And last, we have a firm deadline. If we don't authorize
new user fee programs before the old one expires, FDA will need
to lay off approximately 20 percent of the Device Center and 60
percent of the Drug Center's full-time employees. This would
create a severe personnel shortage and disrupt important public
health programs.
Having said all that, I'm an optimist, and I believe all of
us, Congress and the outside stakeholders alike, can work
together to enact a good user fee bill. The last time we did it
in the 110th Congress, we got a good bill through the Senate
unanimously and on time because we all worked together. I
believe the way to do that is something called the 80 percent
rule. I've learned over the years that for just about any given
problem, reasonable people can agree on 80 percent of the
solution. If we go ahead and get that done, the American people
are very happy.
The problem is that the process of finding common ground is
hard, slow work, and not always very exciting. The 20 percent
where people strongly disagree is much more dramatic. The media
love to cover the 20 percent and make it the story, but my hope
is that we'll focus on the areas of broad agreement.
This committee has had great success on FDA legislation
when we work together. In 2007 the New England Journal of
Medicine said we passed the biggest drug bill in 50 years. We
also gave FDA new authority to regulate tobacco and create new
biosimilar pathways, and just last year Chairman Harkin and I
and the many other members of the HELP Committee worked hard to
give FDA new food safety authorities. We're going to need this
kind of bipartisan inclusion and cooperation to get this done,
and I hope today's hearing kicks off a constructive discussion
on these serious problems.
The Chairman. Thank you very much, Senator Enzi.
And now we'll turn to our only witness today, Commissioner
Hamburg. I'd like to welcome Dr. Hamburg back again to this
committee. Commissioner Hamburg has an impressive background as
a doctor, an NIH scientist, and significant administrative
experience in protecting and promoting the public health from
her previous post at New York's Department of Health and Mental
Hygiene, and here in Washington at the Department of Health and
Human Services.
Commissioner Hamburg is expertly positioned to lead the
agency and to protect the public health as we work to
reauthorize the user fee agreements in this Congress.
Thank you very much, Commissioner, for being here today.
Your statement, which I tried to get through last night, is a
long and very involved statement and very good statement, and
it will be made a part of the record in its entirety, and I'd
ask you to proceed as you so desire. You can ignore the 5-
minute thing there, and if you need to take 10 minutes, please
go ahead and take whatever time. If you start going over 10, I
might start getting a little nervous about that time, but
please proceed as you so desire.
STATEMENT OF MARGARET HAMBURG, M.D., COMMISSIONER, FOOD AND
DRUG ADMINISTRATION, U.S. DEPARTMENT OF HEALTH AND HUMAN
SERVICES, SILVER SPRING, MD
Commissioner Hamburg. Thank you, Mr. Chairman and members
of the committee. I promise that I will be shorter than the
length of my written testimony.
I'm very, very pleased to have the opportunity to be here
and to testify about the Prescription Drug User Fee Act, the
PDUFA, and the Medical Device User Fee Act, or MDUFA.
The enactment of PDUFA back in 1992 was prompted by
concerns that patients in the United States were waiting longer
than patients in other countries for critical therapies,
sometimes with tragic consequences. Through user fees paid by
the drug industry, PDUFA provided FDA with a source of stable,
consistent funding to hire additional reviewers, upgrade IT
systems, and strengthen programs.
At the same time, FDA committed to complete reviews in a
predictable timeframe, to meet more often with industry, and to
provide more guidance.
These changes revolutionized the drug approval process in
the United States and enabled FDA to speed its reviews without
compromising the agency's high standards for safety and
effectiveness, and our commitment to promote and protect the
health of the public.
The time required for FDA approval has been cut by 60
percent since the enactment of PDUFA, and the United States now
leads the world in the first introduction of new active drug
substances. And so far this year, with the assistance of PDUFA
user fees, FDA has approved 21 new ground-breaking medicines,
including treatments for hepatitis C, late-stage prostate
cancer, and lupus. In fact, this is the same number of novel
drugs approved in all of 2010, and we're only in July. So that
is very positive news.
But despite this positive news, we face a severe
productivity problem worldwide in drug development in which an
ever-increasing research and development investment is
producing fewer new drugs. And at the same time, the scientific
opportunities have never been greater due to new biomedical
discoveries. And, of course, this is a complex ecosystem. FDA
represents one important player in addressing this challenge,
but the proposed PDUFA enhancements discussed in my written
testimony include new steps to incorporate scientific advances
into regulations so that we can modernize and streamline our
processes to the benefit of both patients and industry.
The enactment of MDUFA in 2002 was prompted by similar
concerns about the speed of the FDA review process for devices.
User fees paid by the device industry under MDUFA have helped
FDA expand available expertise and staffing, modernize IT
systems, and provide additional guidance to industry. While FDA
is meeting the vast majority of its goals under MDUFA, we know
that the overall time to a decision, FDA time plus the time the
manufacturer spends responding to FDA questions, has increased,
as Senator Enzi noted. FDA and industry share responsibility
for that increase, and FDA has been instituting management
changes to address our role.
As a result, for 2010, total time for lower-risk devices
appears to have stabilized, and preliminary data suggest that
total time for higher-risk devices is improving. We appreciate
that AdvaMed is also working to address the part that poor-
quality applications play in delaying approval by offering
training for its companies regarding FDA standards.
Beyond review times alone, we recognize that significant
concerns have been raised about how well the device review
program is meeting its two goals, ensuring that medical devices
are safe and effective, and fostering medical device
innovation.
In response to these concerns, the agency conducted an
assessment of the 510(k) review program. What we found was that
insufficient predictability in our premarket review programs
was contributing to inconsistent decisions and longer times to
market. The causes included unnecessary or inconsistent data
requirements, insufficient guidance for industry, insufficient
interactions with industry, high reviewer and manager turnover,
insufficient reviewer training, insufficient managerial
oversight, and a rapidly growing workload.
After soliciting public comment on these reports, we
announced this past January 25 specific actions that we will
take in 2011 to improve the predictability, consistency, and
transparency of our pre-market review programs and have since
announced additional actions.
For example, we've committed to developing updated and new
guidances to clarify FDA requirements, and several have been
released in recent days and weeks. We're enhancing the
interactive review process and streamlining the review program
for low to moderate-risk novel medical devices, called the ``de
novo'' process.
We have established a new Center Science Council to help
ensure consistency in our scientific decisionmaking and are
developing a network of experts to help us to resolve complex
scientific issues.
We're instituting a certification program and a pilot
experiential learning program to provide review staff with
necessary training and real-world experiences.
These and other efforts signify our commitment to improving
our pre-market review programs to ensure that patients have
timely access to safe and effective devices and that the U.S.
device industry remains innovative and strong.
PDUFA IV and MDUFA II expire on September 30, 2012, and
we're eager to work with you to achieve their timely
reauthorization. These are critical programs and make possible
the resources and tools that are so vitally needed if we are to
provide the American people with the medical products they need
and the safety and effectiveness they count on.
Thank you for your contributions to the continued success
of PDUFA and MDUFA and to the mission of the Food and Drug
Administration.
And I'm now happy to answer any questions that you may
have.
[The prepared statement of Commissioner Hamburg follows:]
Prepared Statement of Margaret A. Hamburg, M.D.
introduction
Mr. Chairman and members of the committee, I am Dr. Margaret
Hamburg, Commissioner of Food and Drugs at the Food and Drug
Administration (FDA or the Agency). I am pleased to be here today to
discuss the fifth reauthorization of the Prescription Drug User Fee Act
(PDUFA), also referred to as ``PDUFA V,'' and the third reauthorization
of the Medical Device User Fee Act (MDUFA), also referred to as ``MDUFA
III.'' I will also talk about FDA's efforts to promote the science and
innovation necessary to ensure that we are fully equipped to address
the public health issues of the 21st century and to address the
continuing challenges of a global marketplace.
Background on PDUFA
FDA considers the timely review of the safety and effectiveness of
New Drug Applications (NDAs) and Biologics License Applications (BLAs)
to be central to the Agency's mission to protect and promote the public
health. Prior to enactment of PDUFA in 1992, FDA's review process was
understaffed, unpredictable, and slow. FDA lacked sufficient staff to
perform timely reviews, or develop procedures and standards to make the
process more rigorous, consistent and predictable. Access to new
medicines for U.S. patients lagged behind other countries. As a result
of concerns expressed by both industry and patients, Congress enacted
PDUFA, which provided the added funds, through user fees, that enabled
FDA to hire additional reviewers and support staff and upgrade its
information technology systems. At the same time, FDA committed to
complete reviews in a predictable timeframe. These changes
revolutionized the drug approval process in the United States and
enabled FDA to speed the application review process for new drugs
without compromising the Agency's high standards for demonstration of
safety, efficacy, and quality of new drugs prior to approval.
Three fees are collected under PDUFA: application fees,
establishment fees, and product fees. An application fee must be
submitted when certain NDAs or BLAs are submitted. Product and
establishment fees are due annually. The total revenue amounts derived
from each of the categories--application fees, establishment fees, and
product fees--are set by the statute for each fiscal year. PDUFA
permits waivers under certain circumstances, including a waiver of the
application fee for small businesses.
Of the total $931,845,581 obligated in support of the process for
the review of human drug applications in fiscal year 2010, PDUFA fees
funded 62 percent, with the remainder funded through appropriations.
PDUFA Achievements
PDUFA has produced significant benefits for public health,
providing patients faster access to over 1,500 new drugs and biologics,
since enactment in 1992, including treatments for cancer, infectious
diseases, neurological and psychiatric disorders, and cardiovascular
diseases. Importantly, PDUFA has led to the reversal of the ``drug
lag'' that prompted its creation. According to a study published in
Health Affairs in June 2011, of the 35 cancer drugs approved over the
last 7 years in either the United States or Europe, FDA approved 32, in
an average time of 261 days. The European Medicines Agency (EMA)
approved only 26 in an average time of 373 days. All 23 cancer drugs
approved by both agencies during this period were marketed first in the
United States.
As shown in Figure 1, the United States now leads the world in the
first introduction of new active drug substances. According to
researchers at the Tufts Center for the Study of Drug Development, the
time required for the FDA approval phase of new drug development (i.e.
time from submission until approval) has been cut by 60 percent since
the enactment of PDUFA,\1\ from an average of 2.0 years for the
approval phase at the start of PDUFA to an average of 1.1 years today.
So far this year, FDA has approved 21 new, groundbreaking medicines,
including treatments for hepatitis C, late-stage prostate cancer, and
lupus. This is the same number of novel drugs approved in all of 2010.

Protect and Promote Public Health [PowerPoint slides]. Presentation at
the FDA PDUFA Public Meeting, Rockville, MD.
[GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT]
Increased resources provided by user fees have enabled FDA to
provide a large body of technical guidance to industry that clarified
the drug development pathway for many diseases and meet with companies
during drug development to provide critical advice on specific
development programs. In the past 5 years alone, FDA has held over
7,000 meetings within a short time after a sponsor's request.
Innovations in drug development are being advanced by many new
companies as well as more established ones, and new sponsors may need,
and often seek, more regulatory guidance during development. In fiscal
year 2009, more than half of the meetings FDA held with companies at
the early investigational stage and midway through the clinical trial
process were with companies that had no approved product on the U.S.
market.
PDUFA provides FDA with a source of stable, consistent funding that
has made possible our efforts to focus on promoting innovative
therapies and help bring to market critical products for patients. FDA
aims to review priority new molecular entities (NME) more quickly--6
months vs. 10 months for standard drugs. Priority NMEs represent the
truly innovative medicines generally targeted at severe illnesses with
few or no available therapeutic options. FDA reviewers give these drugs
priority attention throughout development, working with sponsors to
determine the most efficient way to collect the data needed to provide
evidence of safety and effectiveness.
Improvements in the efficiency of the drug review process and the
quality of new drug applications is evident in the trends toward
greater first-cycle approvals for priority NMEs. A first-cycle approval
means that the product application is approved after the initial,
complete FDA review, rather than entering another cycle of FDA
questions. Importantly, first-cycle approvals bring innovative drugs
with new benefits to patients sooner. When FDA is presented with high-
quality applications that are based on strong science, we can approve
these products quickly and efficiently. The average first-cycle
approval rate for priority NMEs increased from 46 percent in PDUFA I to
68 percent to date in PDUFA IV, as shown in Figure 2. And I am pleased
to report that we are on track for approving a historically high
percentage of priority NMEs for 2011. First-cycle approval rates have
also increased for standard NMEs from an average of 30 percent in PDUFA
I to 38 percent to date in PDUFA IV.
[GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT]
It should be noted that FDA assesses the benefit-risk of new drugs
on a case-by-case basis, considering the degree of unmet medical need
and the severity and morbidity of the condition the drug is intended to
treat. This approach has been critical to increasing patient access to
new drugs for cancer and rare and other serious diseases, where
existing therapies have been few and limited in their effectiveness.
Some of these products have serious side effects but they were approved
because the benefit outweighed the risk. For example, in March of this
year, FDA approved Yervoy (ipilimumab) for the treatment of
unresectable or metastatic melanoma. Yervoy also poses a risk of
serious side effects, including severe to fatal autoimmune reactions,
in 12.9 percent of patients treated with Yervoy. FDA decided that the
benefits of Yervoy outweighed its risk, especially considering that no
other melanoma treatment has been shown to prolong a patient's life.
PDUFA funds help support the use of existing mechanisms in place to
expedite the approval of certain promising investigational drugs, and
also to make them available to the very ill as early in the development
process as possible, without unduly jeopardizing the patients' safety.
One such program is accelerated approval. In 1992, FDA instituted the
accelerated approval process, which allows earlier approval of drugs
that treat serious diseases and that fill an unmet medical need based
on a surrogate endpoint that is reasonably likely to predict clinical
benefit, but is not fully validated to do so. A surrogate endpoint is a
marker--a laboratory measurement, or physical sign--that is used in
clinical trials as an indirect or substitute measurement for a
clinically meaningful outcome, such as survival or symptom improvement.
The use of a surrogate endpoint can considerably shorten the time to
approval. Approval of a drug based on an unvalidated surrogate endpoint
is given on the condition that post-marketing clinical trials verify
the anticipated clinical benefit. Over 60 critical products have been
approved under accelerated approval since the program was established.
While the best means of providing access to useful medical
treatments for all Americans is to approve drugs proven to be safe and
effective, FDA also recognizes circumstances in which there is public
health value in making products available prior to marketing approval.
A promising but not yet fully evaluated treatment may sometimes
represent the best choice for individuals with serious or life-
threatening diseases who lack a satisfactory therapy.
FDA allows for access to investigational products through multiple
mechanisms. Clinical trials are the best mechanism for a patient to
receive an investigational drug, because they provide a range of
patient protections and benefits and they maximize the gathering of
useful information about the product, which benefits the entire patient
population. However, there are times when an individual cannot enroll
in a clinical trial. In these cases, the patient may gain access to an
investigational therapy through one of the alternative mechanisms, and
FDA's Office of Special Health Issues assists patients and their
doctors in this endeavor.
Drug Safety Activities
In parallel with improvements in the drug review process, FDA has
increased its focus on safety, including implementing the Food and Drug
Administration Amendments Act of 2007 (FDAAA). In FDAAA, Congress
authorized additional user fees totaling $225 million for the 5 years
of PDUFA IV reauthorization to enhance drug safety activities. FDAAA
also provided FDA with important post-market safety authorities. Under
FDAAA, FDA was given the ability to require post-marketing studies and
clinical trials to address important drug safety questions. Between the
enactment of FDAAA on September 27, 2007, and June 1, 2011, FDA has
required sponsors to conduct approximately 375 post-marketing studies
or trials to address important drug safety questions that could not be
addressed before the drug was approved. FDAAA also gave FDA the
authority to require safety labeling changes based on new safety
information identified after a drug is on the market. FDA has used its
new authority to require sponsors to place important new safety
information onto their drug labels quickly, in some cases using this
authority to require changes to the labeling of all members of a class
of drugs. FDAAA also provided FDA with authority to manage risks
associated with marketed drug products through required Risk Evaluation
and Mitigation Strategies (REMS). FDA has been using this new authority
judiciously to ensure that drugs that could not otherwise be approved
because the risks without a REMS would outweigh the benefits, are
available to patients.
Challenges for the Current Drug Program
Although we can report many important successes with the current
program, new challenges have also emerged that offer an opportunity for
further enhancement. While new FDAAA process requirements have
strengthened drug safety, they have put strains on FDA's ability to
meet pre-market review performance goals and address post-market review
activities. In addition, there has been a significant increase in the
number of foreign sites included in clinical trials to test drug safety
and effectiveness, and an increase in the number of foreign facilities
used in manufacturing new drugs for the U.S. market. While foreign
sites can play an important role in enabling access to new drugs, the
need to travel much farther to conduct pre-approval inspections for
clinical trials and manufacturing sites overseas has created additional
challenges for completion of FDA's review within the existing PDUFA
review performance goals, while at the same time trying to communicate
with sponsors to see if identified issues can be resolved before the
review performance goal date.
Despite these challenges, FDA has maintained strong performance in
meeting the PDUFA application review goals, with the exception of a dip
in fiscal year 2008-9, when staff resources were shifted to ensure
timely implementation of all the new FDAAA provisions that affected
activities in the new drug review process. This is shown in Figure 3.
[GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT]
However, FDA wants to meet not only the letter (i.e., PDUFA goal
dates), but also the spirit of the PDUFA program--speeding patient
access to drugs shown to be safe and effective for the indicated uses.
Although the NDA/BLA approval phase of drug development (the phase
in which FDA plays the biggest role) is reported to have the highest
success rate of any phase of drug development, it is critical to our
public health mission that we work with industry and other stakeholders
to take steps to reduce uncertainty and increase the success of all
phases of drug development. We must leverage advances in science and
technology to make sure that we have the knowledge and tools we need to
rapidly and meaningfully evaluate medical products. The science of
developing new tools, standards, and approaches to assess the safety,
efficacy, quality, and performance of FDA-regulated products--known as
``regulatory science''--is not exclusively about helping drug
development to speed it along before it gets to FDA for review and
approval. It also gives us the scientific tools to modernize and
streamline our regulatory process. With so much at stake for public
health, FDA has made advances in regulatory science a top priority. The
Agency is both supporting mission-critical science at FDA and exploring
a range of new partnerships with the National Institutes of Health and
academic institutions to develop the science needed to maximize
advances in biomedical research and bring the development and
assessment of promising new therapies and devices into the 21st
century. With this effort, FDA is poised to support a wave of
innovation to transform medicine and save lives.
For example, FDA is working to improve the science behind certain
clinical trial designs. Recent advances in two clinical trial designs--
called non-inferiority and adaptive designs--have required FDA to
conduct more complex reviews of clinical trial protocols and new
marketing applications. Improving the scientific bases of these trial
designs should add efficiency to the drug review process, encourage the
development of novel products, and speed new therapies to patients.
FDA has also taken steps to facilitate the development and approval
of safe and effective drugs for Americans with rare diseases. Therapies
for rare diseases--those affecting fewer than 200,000 people in the
United States--represent the most rapidly expanding area of drug
development. Although each disease affects a relatively small
population, collectively, rare diseases affect about 25 million
Americans. Approximately one-third of the NMEs and new biological
products approved in the last 5 years have been drugs for rare
diseases. Because of the small numbers of patients who suffer from each
disease, FDA often allows non-traditional approaches to establishing
safety and effectiveness. For example, FDA recently approved Carbaglu
(carglumic acid) for the treatment of N-acetylglutamate synthase (NAGS)
deficiency, a rare disorder of the urea cycle, caused by a genetic
deficiency or absence of the NAGS enzyme that results in severe
elevations in plasma ammonia levels and can rapidly result in injury to
the brain or death. There have only been approximately 50 known cases
reported in the literature worldwide to date. The disease can be
diagnosed throughout life, but in infants, the disease can be rapidly
fatal due to severe hyperammonemia that can result in cerebral edema,
seizures, and death. FDA approved this drug in March 2010, based on the
results of a single, non-concurrently controlled, retrospective review
of the clinical course of 23 patients with NAGS deficiency treated with
Carbaglu over a 21-year period.
background on mdufa
Similar to the PDUFA program, the enactment of the Medical Device
User Fee and Modernization Act in 2002 (MDUFMA I) was prompted by
growing concerns about the medical device review program's capacity and
performance. MDUFMA I and the Medical Device User Fee Act of 2007
(MDUFA II) authorized user fees for the review of medical device pre-
market applications, reports, supplements, and pre-market notification
submissions. These additional resources enabled FDA to make its reviews
more timely, predictable, and transparent to applicants. MDUFA fees and
mandated appropriations for the medical device program helped FDA
expand available expertise, modernize its information management
systems, provide new review options, and provide more guidance to
prospective applicants.
MDUFA authorizes FDA to collect user fees for certain medical
device applications, the registration of certain medical device
establishments, and certain other purposes. Small businesses may
qualify for a waiver or a reduced fee on certain submissions to FDA.
Of the total $292,707,540 obligated in support of the process for
the review of medical device submissions in fiscal year 2010, MDUFA
fees currently fund about 20 percent. The remainder of the funding is
through appropriations.
mdufa achievements
FDA has consistently met or exceeded goals agreed to by FDA and
industry under MDUFA II for approximately 95 percent of the submissions
we review each year. FDA consistently completes at least 90 percent of
pre-market notification, or 510(k), reviews within 90 days or less,
which meets the applicable goal. In the limited areas where FDA is not
yet meeting its MDUFA II goals, the Agency's performance has been
steadily improving, despite growing device complexity and an increased
workload, and without a commensurate increase in user fees. And FDA is
committed to continued improvements in the device approval process to
address legitimate concerns raised by industry and other stakeholders,
which I will discuss later in this testimony.
MDUFA II metrics reflect FDA time only; they do not reflect the
time taken by industry to respond to requests from FDA for additional
information. As Figure 4 and 5 illustrate, while the time FDA spends
reviewing an application has improved for both low- and high-risk
devices, overall time to decision--the time that FDA has the
application, plus the time the manufacturer spends answering any
questions FDA may have--has increased. FDA and industry share
responsibility for the increase in overall time to final decision, and
FDA has been instituting management changes to address this. As a
result, in 2010, total time for 510(k)s appears to have stabilized and
preliminary data suggest that the total time for pre-market approval
(PMA) decisions is improving.
[GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT]
FDA is committed to working on ways to streamline the regulatory
review process. Success will require that we continue to focus on our
own internal process, but industry also bears responsibility for the
increase in overall time to a decision. Poor-quality submissions that
need to be addressed are significant contributors to delays in pre-
market reviews. These include submissions that do not adhere to current
guidance documents and existing standards that contain inadequate
clinical data (e.g., missing data, or data that fail to meet
endpoints), or that deviate from the study protocol agreed upon.
Figure 6 shows the steep and prolonged increase, since fiscal year
2002, in the percentage of 510(k) submissions requiring an Additional
Information (AI) letter after the first review cycle. The increasing
number of AI letters has contributed to the increasing total time from
submission to decision. Over 80 percent of AI letters were sent because
of problems with the quality of the submission. These submission
quality problems waste FDA and sponsor time and resources and divert
FDA resources from pending, higher-quality applications.
[GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT]
We are pleased that, in response to FDA calls for improving the
quality of pre-market submissions, AdvaMed has made available training
courses for its companies to help them develop 510(k) and PMA
submissions that meet FDA standards.
Medical Device Safety
The Food and Drug Administration Amendments Act of 2007 (FDAAA)
authorized appropriations of $39,231,982 in MDUFA user fees for fiscal
year 2008-fiscal year 2012 for the collecting, developing, reviewing,
and evaluating of post-market safety information on medical devices.
This includes activities such as the Post-Approval Studies Program
(Program) at the Agency's Center for Devices and Radiological Health
(CDRH), which encompasses the design, tracking, oversight, and review
of studies mandated as a condition of approval of pre-market
applications. This Program guides industry in the design of
scientifically sound and feasible post-market studies that address
relevant safety questions and ultimately provide valuable data for
ongoing device evaluations. CDRH has also established a Center
Electronic Submissions (CeSub) system that provides for electronic
submission of adverse event reports and an efficient method for staff
to perform analyses that bridge pre-market and post-market device
safety data in support of the device review process. In addition, CDRH
scientific investigations provide in-depth analyses of the underlying
causes of post-market device safety issues, which increase reviewer
understanding of issues that occur in marketed products. Findings from
these scientific investigations are provided to industry to facilitate
the redesign of existing devices and guide device development along
paths that allow for the most efficient determination of device safety
and effectiveness.
Challenges for the Medical Device Program
FDA recognizes that concerns have been raised about how well CDRH's
pre-market review program is meeting its two goals of ensuring that
medical devices are safe and effective and fostering medical device
innovation. Some stakeholders--particularly in industry--have argued
that a lack of predictability, consistency, and transparency in the
510(k) program is stifling medical device innovation in the United
States and driving companies (and jobs) overseas. Other groups,
including health care professional, patient, and third-party payer
organizations, have argued that the 510(k) program allows devices to
enter the market without sufficient evidence of safety and
effectiveness, thereby putting patients at unnecessary risk and failing
to provide practitioners with the necessary information to make well-
informed treatment and diagnostic decisions.
In response to these concerns--and because FDA is continually
looking for ways to improve its performance in helping to bring safe
and effective devices to market--the Agency conducted an assessment of
the 510(k) review program and an assessment of how it uses science in
regulatory decisionmaking, which addressed aspects of its other pre-
market review programs.
The two reports we released publicly in August 2010, with our
analyses and recommendations, showed that we have not done as good a
job managing our pre-market review programs as we should and that we
needed to take several critical actions to improve the predictability,
consistency, and transparency of these programs.
For example, we have new reviewers who need better training. We
need to improve management oversight and standard operating procedures.
We need to provide greater clarity for our staff and for industry
through guidance about key parts of our pre-market review and clinical
trial programs and how we make benefit-risk determinations. We need to
provide greater clarity for industry through guidance and expanded
interactions about what we need from them to facilitate more efficient,
predictable reviews. We need to make greater use of outside experts who
understand cutting-edge technologies. And we need to find the means to
handle the ever-increasing workload and reduce staff and manager
turnover, which is almost double that of the FDA's drugs and biologics
centers. We are making progress in these areas.
The Agency solicited public comment on the recommendations
identified in the studies and received a range of perspectives from
stakeholders throughout the process at two public meetings and three
town hall meetings, through three open public dockets and via many
meetings with stakeholders. FDA received seventy-six (76) comments from
medical device companies, industry representatives, venture
capitalists, health care professional organizations, third-party
payers, patient and consumer advocacy groups, foreign regulatory
bodies, and others.
After considering the public input, in January 2011 FDA announced
25 specific actions that the Agency will take this year to improve the
predictability, consistency, and transparency of our pre-market review
programs. Since then, FDA has announced additional efforts, including
actions to improve its program for clinical trials and the
Investigational Device Exemptions (IDE) program. These are based on an
analysis of this program that the Agency committed to as part of its
January 2011 announcement.
These actions, many of which were supported by industry, include:
Developing a range of updated and new guidances to clarify
CDRH requirements for timely and consistent product review, including
device-specific guidance in several areas such as mobile applications
(released in July 2011) and artificial pancreas systems (to be
completed by the end of 2011), and draft guidance that clarifies the
kinds of changes that trigger the need for a new submission (released
July 27, 2011);
Revamping the guidance development process through a new
tracking system and core staff to oversee the timely drafting and
clearance of documents (to be completed by the end of 2011);
Improving communication between FDA and industry through
enhancements to interactive review (some of these enhancements will be
in place by the end of 2011);
Streamlining the de novo review process, to provide a more
efficient pathway to market for novel devices that are low to moderate
risk. This new structure will be described in draft guidance for
industry that is expected to be available for public comment by
September 30, 2011;
Streamlining the clinical trial and IDE processes by
providing industry with specific guidance on how to improve the quality
and performance of clinical trials. (IDEs are required before device
testing in humans may begin, and they ensure that the rights and
welfare of human subjects are protected while gathering data on the
safety and efficacy of medical products.) We are also developing
guidance to clarify the criteria for approving clinical trials, and
criteria for when a first-inhuman study can be conducted earlier during
device development (to be issued by October 31, 2011);
Establishment of an internal Center Science Council to
actively monitor the quality and performance of the Center's scientific
programs and ensure consistency and predictability in CDRH scientific
decisionmaking (already completed);
Creating a network of experts to help the Center resolve
complex scientific issues, which will ultimately result in more timely
reviews. This network will be especially helpful as FDA confronts new
technologies (expected in place by the end of 2011);
Instituting a mandatory Reviewer Certification Program for
new reviewers (to be completed by September 2011); and,
Instituting a pilot Experiential Learning Program to
provide review staff with real-world training experiences as they
participate in visits to manufacturers, research and health care
facilities, and academia (to begin in early 2012).
For manufacturers and FDA, ``not substantially equivalent'' (NSE)
determinations often represent an inefficient use of time and
resources. NSE determinations require significant Agency resources and
time, yet fail to result in the marketing of a new product. The
following chart shows a spike in the percentage of 510(k) decisions
that were NSE in 2010. Among the reasons that 510(k) submissions result
in NSE determinations are: lack of a suitable predicate device;
intended use of the new device is not the same as the intended use of
the predicate; technological characteristics are different from those
of the predicate and raise new questions of safety and effectiveness;
and/or performance data failed to demonstrate that the device is as
safe and effective as the predicate. The vast majority of NSE decisions
are due to the absence of adequate performance data, sometimes despite
repeated FDA requests.
I'm pleased to report that, consistent with our many improvements
to the 510(k) program, the recent increase in the NSE rate appears to
be turning around. From a peak of 8 percent in 2010, the NSE rate has
decreased to 5 percent through the first 8 months of 2011. Just as
important, we also may be seeing a reversal in the trend of declining
rate in Substantially Equivalent (SE) decisions that clear a 510(k)
submission for marketing. After several years of declining percentages,
reaching a low of 73 percent in 2010, we are seeing an increase of 4
percent through the first 8 months of 2011, as shown in Figure 7.

Facilitating medical device innovation is a top priority for FDA.
As part of its 2010 and 2011 Strategic Plans, FDA's medical device
center has set goals to proactively facilitate innovation to address
unmet public health needs. FDA's Innovation Initiative seeks to
accelerate the development and regulatory evaluation of innovative
medical devices, strengthen the Nation's research infrastructure for
developing breakthrough technologies, and advance quality regulatory
science. As part of this initiative, CDRH proposed additional actions
to encourage innovation, streamline regulatory and scientific device
evaluation, and expedite the delivery of novel, important, safe and
effective innovative medical devices to patients, including:
Establishing the Innovation Pathway, a priority review
program to expedite development, assessment, and review of important
technologies;
Advancing regulatory science through public-private
partnerships;
Facilitating the creation of a publicly available core
curriculum for medical device development and testing to train the next
generation of innovators; and
Engaging in formal horizon scanning--the systematic
monitoring of medical literature and scientific funding to predict
where technology is heading, in order to prepare for and respond to
transformative, innovative technologies and scientific breakthroughs.
A public docket has been set up to solicit public comment on the
Innovation Initiative proposals, and a public meeting on the topic took
place on March 15, 2011 In the near future, FDA will announce actions
it plans to take under the Initiative.
PDUFA/MDUFA Reauthorization
With the reauthorization of PDUFA and MDUFA in 2007, Congress
directed FDA to take additional steps to ensure that public
stakeholders would have adequate opportunity to provide input to any
program enhancements for PDUFA and MDUFA. In addition to receiving
input from an initial public meeting, Congress directed the Agency to
meet with public stakeholders every month while conducting negotiations
with regulated industry, to hold discussions on their views on the
reauthorization and hear their suggestions for changes to the PDUFA and
MDUFA performance goals. After negotiations with regulated industry
have concluded, PDUFA and MDUFA require that FDA present
recommendations to congressional committees relating to reauthorization
of those programs, publish such recommendations in the Federal Register
for public comment, and hold a public meeting. Final PDUFA and MDUFA
recommendations must be submitted to Congress no later than January 15,
2012. Below I will summarize the status of our PDUFA and MDUFA
negotiations.
PDUFA Negotiations
Based on a public meeting held in April 2010, input from a public
docket, and the Agency's own internal analyses of program challenge
areas, FDA developed a set of potential proposed enhancements for PDUFA
V. In July 2010, FDA began negotiations with industry and parallel
discussions with public stakeholders. These discussions were concluded
in May 2011, and the enhancements are under internal review.
We are very pleased to report that seven categories of enhancements
for PDUFA V are under consideration. These enhancements address many of
the top priorities identified by public stakeholders, the top concerns
identified by industry, and the most important challenges identified
within FDA. I will briefly summarize the enhancements under
consideration.
Drug Review Process: Increase the number of meetings
between FDA and sponsors during FDA's review of NME NDAs and original
BLAs, including pre-submission meetings, mid-cycle communications, and
late-cycle meetings. To accommodate this increased interaction during
regulatory review, FDA's review clock would begin after the 60-day
administrative filing review period, rather than immediately upon
filing. The impact of these modifications on the efficiency of drug
review for this subset of applications would be assessed during PDUFA
V.
Regulatory science: Regulatory science is the science of
developing and applying new tools, standards and approaches to assess
the safety, effectiveness, quality and performance of FDA-regulated
products. Under consideration for PDUFA V are:
Promoting innovation by establishing a dedicated drug
development communication and training staff. This staff will
be responsible for identifying best practices for communication
between the Agency and sponsors, training review staff, and
disseminating best practices through published guidance.
Developing a dedicated staff to evaluate best
practices and limitations in meta-analysis methods. A meta-
analysis typically attempts to combine the data or findings
from multiple completed studies to explore drug benefits and
risks and, in some cases, uncover what might be a potential
safety signal in a pre-market or post-market context.
Augmenting the Agency's clinical, clinical
pharmacology, and statistical capacity to adequately address
submissions that propose to utilize biomarkers or
pharmacogenomic markers. Pharmacogenomics and the application
of qualified biomarkers have the potential to decrease drug
development time by helping to demonstrate benefits, establish
unmet medical needs, and identify patients who are pre-disposed
to adverse events.
Improving FDA's clinical and statistical capacity to
address submissions involving patient-reported outcomes (PROs)
and other endpoint assessment tools, including providing
consultation during the early stages of drug development. PROs
measure treatment benefit or risk in medical product clinical
trials from the patients' points of view. They are critical in
understanding the drug benefits and harm from the patients'
perspectives.
Facilitating rare disease drug development by issuing
relevant guidance, increasing the Agency's outreach efforts to
the rare disease patient community, and providing specialized
training in rare disease drug development for sponsors and FDA
staff.
Enhancing Benefit-Risk Assessment: Part of FDA's
decisionmaking lies in understanding the condition treated and the
unmet medical need. Patients who live with a disease have a direct
stake in the outcome of the drug review process. The FDA drug review
process could benefit from a more systematic and expansive approach to
obtaining the patient perspective on disease severity and the potential
gaps or limitations in available treatments in a therapeutic area.
PDUFA V enhancements include expanded implementation of FDA's benefit-
risk framework in the drug review process, including holding public
workshops to discuss the application of frameworks for considering
benefits and risks that are most appropriate for the regulatory
setting. FDA will also conduct a series of public meetings between its
review divisions and the relevant patient advocacy communities to
review treatments available for specific indications or disease states.
Enhancement and Modernization of the FDA Drug Safety
System: Two post-market, safety-focused initiatives are being
considered. First, PDUFA V enhancements would initiate a public process
to standardize REMS with the goal of reducing burden on practitioners,
patients, and others in the health care setting; additionally, FDA
would conduct public workshops and develop guidance on methods for
assessing the effectiveness of REMS and the impact on patient access
and burden on the health care system. Second, FDA would use user fee
funds to conduct a series of activities to determine the feasibility of
using Sentinel, a long-term program designed to build and implement a
national electronic system for monitoring the safety of FDA-approved
medical products, to evaluate drug safety issues that may require
regulatory action, e.g., labeling changes, post-marketing requirements,
or post-marketing commitments. This may shorten the time it takes to
better understand new or emerging drug safety issues, and may reduce
the Agency's reliance on required post-marketing studies and clinical
trials.
Required Electronic Submissions and Standardization of
Electronic
Application Data: PDUFA V enhancements being considered include a
phased-in requirement for standardized, fully electronic submissions
for all marketing and investigational applications; this would
facilitate a more timely and efficient rigorous review within PDUFA
goal timeframes. The Agency would also conduct a public process to
develop standardized terminology for clinical and nonclinical data
submitted in marketing and investigational applications. Standardized
data would translate into a more standardized approach to risk-benefit
assessment and would be helpful in safety analyses that inform FDA
decisions related to post-marketing requirements.
User Fee Increase for PDUFA V: Implementing these PDUFA
enhancements being considered would add $40.4 million to the estimated
PDUFA user fee revenue amount in fiscal year 2012. This translates to a
modest 6 percent increase, and a total estimated base of $712.8 million
in fiscal year 2013.\2\
---------------------------------------------------------------------------
\2\ The fiscal year 2012 estimated user fee amount is $672.4
million. The exact amount will be determined when we have the final-
year workload data for PDUFA IV. That number would be used to calculate
the exact fee amounts for fiscal year 2013, the first year of PDUFA V.
---------------------------------------------------------------------------
Modified Inflation Adjuster and Additional Evaluations of
the Workload Adjuster: PDUFA V enhancements being considered include a
modification to the inflation adjuster to accurately account for
changes in its costs related to payroll compensation and benefits as
well as changes in non-payroll costs. FDA would continue evaluating the
workload adjuster that was developed during the PDUFA IV negotiations
to ensure that it continues to adequately capture changes in FDA's
workload.
MDUFA Negotiations
In September 2010, prior to beginning negotiations with the
regulated industry, FDA held a public meeting attended by a variety of
stakeholders, including regulated industry, scientific and academic
experts, health care professionals, and representatives of patient and
consumer advocacy groups. FDA heard stakeholders' views on medical
device user fee reauthorization, including the public's assessment of
the overall performance of the MDUFA program and opinions as to which
aspects of the program should be retained, changed, or discontinued in
order to further strengthen and improve the program.
Since January 2011, FDA has been holding discussions with regulated
industry in an effort to develop a package of proposed recommendations
for MDUFA reauthorization. Upon completion of these negotiations and
discussions, FDA intends to develop a package of proposed
recommendations for reauthorization of the MDUFA program. The public
will have an opportunity to comment on these proposals prior to FDA's
submission of MDUFA recommendations to Congress in January 2012.
Biosimilar User Fees
The Affordable Care Act directed FDA to develop a user fee program
for review of biosimilar and interchangeable biological products. On
May 9, 2011, FDA published a Federal Register notice to seek public
comment on a proposed stakeholder meeting process and proposed
principles for developing a user fee for biosimilar review. This
summer, FDA is conducting a series of meetings and will develop a set
of proposed recommendations. This fall, we plan to brief Congress on
the recommendations, publishing them in the Federal Register for
comment, and presenting them at a public meeting. After the public
meeting, the proposed recommendations would be revised as necessary
before transmittal to Congress by January 15, 2012. FDA expects to
publish general guidance on biosimilar drug development by the end of
2011. FDA is currently actively meeting with sponsors interested in
developing biosimilar drugs and providing advice specific to their
individual development programs.
Generic Drug User Fees
The Administration supports legislation authorizing generic drug
user fees. We have made significant progress in our current generic
user fee negotiations and believe we can reach a final agreement with
industry and submit recommendations to Congress as soon as possible. We
expect such fees would reduce the currently pending application queue
(the so-called ``backlog'') and permit FDA to process generic drug
applications on a more timely basis.
The Challenges Posed by Globalization
In addition to reauthorizing PDUFA and MDUFA, FDA is also committed
to meeting challenges posed by increased globalization. When President
Franklin Delano Roosevelt established the modern FDA in 1938, the
percentage of food and medical products imported into the United States
was minimal. Today, approximately half of all medical devices used and
40 percent of the drugs Americans take are manufactured outside our
borders, and up to 80 percent of the active pharmaceutical ingredients
in those drugs comes from foreign sources. Last month, FDA published a
special report, ``Pathway to Global Product Safety and Quality,'' our
global strategy and action plan that will allow us to more effectively
oversee the safety of all products that reach U.S. consumers in the
future. Over the next decade, FDA will transform itself from a domestic
Agency, operating in a globalized world, to a truly global Agency fully
prepared for a regulatory environment in which product safety and
quality know no borders. To achieve this transformation, the Agency is
developing a new, more international operating model that relies on
strengthened collaboration, improved information sharing and gathering,
data-driven risk analytics, and the smart allocation of resources
through partnerships with counterpart regulatory agencies, other
government entities, international organizations, and other key
stakeholders, including industry.
Toward this goal, I recently created a directorate focused on
grappling with the truly global nature of today's world--food and drug
production and supply, as well as the science that undergirds the
products we regulate--so that FDA can move from being a regulator of
domestic products to one overseeing a worldwide enterprise. I have
appointed a Deputy Commissioner for Global Regulatory Operations and
Policy to provide broad direction and support to FDA's Office of
Regulatory Affairs and Office of International Programs, with a mandate
from me to make response to the challenges of globalization and import
safety a top priority in the years to come and to ensure that we fully
integrate our domestic and international programs to best promote and
protect the health of the public.
New regulatory authorities may help ensure that we can hold
industry accountable for the security and integrity of their supply
chains and the quality control systems they use to produce medical
products for the American people. In our increasingly complex and
globalized world, additional authorities could be important tools to
help support FDA's efforts to protect the safety of imports and the
health of our citizens.
conclusion
PDUFA IV and MDUFA II expire on September 30, 2012, and FDA is
ready to work with you to ensure timely reauthorization of these
critical programs. If we are to sustain and build on our record of
accomplishment, it is critical that these reauthorizations occur
seamlessly, without any gap between the expiration of the old law and
the enactment of PDUFA V and MDUFA III. Thank you for your
contributions to the continued success of PDUFA and MDUFA and to the
mission of FDA. I am happy to answer questions you may have.
The Chairman. Dr. Hamburg, thank you very much. We'll start
a round of 5-minute questions.
First of all, let me compliment you and your leadership of
the agency. It's not very often--I think it's very rare--that
we get the administrator of any agency here before this
committee or any other committee on which I serve. That, quite
frankly, says that some of the things they were doing weren't
quite right and they've taken action to correct them. I
compliment you both for your investigation and your overview of
that and for what you did in January to make the necessary
changes. I think that is exemplary, so I really appreciate what
you've done in that regard on the premarket approval and the
510(k).
Let me ask a general question. If we did not reauthorize
user fees or didn't do so on time, what repercussions would
that have for patients? Now, I know what it does to industry. I
want to think about the patients. Can you give us some thought
on that?
Commissioner Hamburg. Of course, I worry that it would have
enormous negative implications for patients because we would
see significant delays in our ability to review and approve
applications of promising medical products that could make a
difference in treating, preventing, diagnosing and potentially
curing medical conditions from which they suffer.
These user fee programs represent a very important
component of our medical product review capabilities. They help
to ensure, especially at a time of tightening budget
constraints, a source of stable, reliable funding for our
critical activities, for activities that, of course, involve
our premarket review of candidate products, as well as our
ability to provide management and oversight throughout the
whole life cycle of a product and ensure the safety and
effectiveness that Americans do so rely on.
The Chairman. Thank you, Dr. Hamburg. You mentioned in your
testimony the importance of regulatory science. I never thought
of it as being a science. But can you explain what that is and
how it helps to facilitate innovation, and what are you doing
to further this regulatory science?
Commissioner Hamburg. Yes. This is an area of science that
I have become deeply passionate about since becoming FDA
commissioner, because as I've looked out over the landscape and
looked inward in terms of our capacities, it is clear that we
are not adequately harnessing advances in science and
technology to really promote the development of new medical
products and the knowledge and tools to enable their swift and
meaningful review and approval.
When I talk about regulatory science from the perspective
of FDA, it's the knowledge and tools that we need to
effectively and efficiently review for safety, efficacy,
quality and performance, and it really is a gap in our overall
scientific enterprise, and I think it's increasingly recognized
within the scientific community as a critical gap.
And certainly academia, industry, and government, NIH, FDA,
and other scientific agencies within government need to come
together to really build this area of science to give us the
ability, for example, to usher in the era of personalized
medicine so that we can really identify the genetic traits and
biomarkers that will enable us to target therapies in sub-
populations of responders; to develop innovative new clinical
trial models that will give us robust scientific answers, but
in a more timely and cost-effective way; to enable us to really
mine the available sources of data both to inform us about
important aspects of the effectiveness of products, including
this issue of sub-populations of responders, but also to enable
us to look in the postapproval, postmarket period to really
monitor for emerging safety signals.
There are a host of ways that targeted investments in the
area of regulatory science can really enable us to bridge that
gap between investments in biomedical research and the
opportunities and discoveries that exist today, and the
translation of those discoveries into real-world products, and
that's what we're really focusing on, and in partnership with
the other key stakeholders--patients, industry, academia, and
particularly the National Institutes of Health, our sister
scientific agency within HHS.
The Chairman. Thank you very much, Dr. Hamburg. My time has
expired.
Senator Enzi.
Senator Enzi. Thank you, Mr. Chairman.
A Wall Street Journal opinion piece yesterday talked about
genomic sequencing and other new technologies that are going to
usher in this era of personalized medicine. Last year the FDA
approved 20 new drugs, but in the future it may be necessary to
target hundreds or maybe thousands of drugs for specific
patients. I know you've thought a lot about personalized
medicine. How is the FDA's pre-market approval system preparing
for that future?
Commissioner Hamburg. I think, as I was just describing,
this expansion of knowledge through investments in regulatory
science and partnership is going to be very, very important.
The models for drug development are certainly changing, and we
are recognizing that the future, to really serve patients, is
to try to better understand what therapies really work for what
patients and why, and to better understand not just
effectiveness but also safety, because we are increasingly
realizing that there are subgroups of patients that may develop
serious adverse events in response to a treatment, and others
will not, and the more we can understand and target those
therapies, the better we can serve patients and consumers.
So it is, on the part of industry and the part of FDA, a
new world. We are trying to really clarify the regulatory
expectations for these new kinds of products, often products
that involve combining a device, a diagnostic with a
therapeutic intervention, and so it requires more teamwork
within FDA. It also requires new ways for companies to develop
and present products to us. We are trying to clarify our
regulatory pathways, as well as to develop the underlying
science to enable those pathways to be as modern and
streamlined as possible.
And just within recent weeks, we did release a new guidance
on combination--on companion diagnostics to help us move into
this era of personalized medicine, and to help industry
understand our expectations and standards.
Senator Enzi. I appreciate the thought that you've given
it.
The Institute of Medicine is expected to make their
recommendations tomorrow, I think, on how the FDA should change
the 510(k) process. What process will the FDA use to evaluate
and act on those recommendations, and will you have a notice
and comment period?
Commissioner Hamburg. We will welcome, of course, the IOM
report and its recommendations, but they are just
recommendations, and we will review them internally and engage
with stakeholders to get their perspectives on the
recommendations. Any actions that we would take in terms of
program or policy change that would emerge from the
recommendations of the IOM report would be done in an open and
transparent process with lots of opportunity for discussion,
for notice and comment and feedback as we go forward.
Senator Enzi. Thank you. And the last PDUFA reauthorization
contained some new rules on conflicts of interest for the
advisory committees. Are these rules making it harder for the
FDA to get qualified experts on the advisory committees,
especially for the rare diseases?
Commissioner Hamburg. This is a very important question
and, frankly, something that comes up in many contexts.
Whatever groups I'm meeting with, whether it's patients and
consumers, scientific societies and organizations, academic
organizations, industry, we do hear the concern about are you
able to get the experts that you need on your advisory
committees.
We work very hard to get the appropriate experts, and in
rare instances we can waive conflict of interest requirements
in order to get the experts that we need. But I think it's
something we need to--it's a dynamic process. We need to keep
looking at it, especially, as you note, when you're talking
about rare, unusual diseases, getting the people with true
expertise is more challenging, and they're often ones that have
been involved in some aspect of the development of new drugs or
products for that disease condition.
And so we are certainly talking with our various
stakeholders, happy to explore this issue further with you as
well, because at the end of the day, we depend on the best
possible science to make our decisions, and getting that
external expertise is very, very critical.
Senator Enzi. Thank you. My time has expired.
Thank you, Mr. Chairman.
The Chairman. Thank you, Senator Enzi.
In order of appearance, then, it would be the following. It
would be Senator Franken, Senator Burr, Senator Hagan, Senator
Isakson, Senator Bennet, Senator Alexander, Senator Murray,
Senator Mikulski, and Senator Merkley.
And we'll recognize Senator Franken.
Statement of Senator Franken
Senator Franken. Thank you, Mr. Chairman.
Dr. Hamburg, I think we can all agree that patient safety
is a priority of Congress and a priority of the FDA, and it is
my job and the job of the entire HELP Committee to help you to
protect patient safety to the best of our ability.
When I talk to patients in Minnesota, they also tell me
that they want to be able to access medical devices that have
been developed, and their doctors want to provide them with the
best devices for their conditions, but too often these devices
haven't been approved by the FDA.
And when I talk to the medical device manufacturers in
Minnesota, they tell me how frustrated they are that they're
developing innovative and potentially life-saving devices, but
they can't get them to their patients because the FDA is taking
so long to approve the devices.
You and I both know that it takes time and effort for the
FDA to thoroughly review devices for safety and effectiveness,
but I believe that we can make the FDA processes more
efficient, more predictable, and better support and reward
biomedical innovation.
I really want to get into three areas here, and I just want
to use my time wisely. But I just want to summarize them before
I ask questions.
No. 1, is improving coordination between the FDA and the
medical device industry and how we can do that.
No. 2, speaking to what Senator Enzi spoke to--dealing with
FDA rules on conflict of interest, and so how you can avail
yourself of expertise outside the agency when the review staff
is confronted with novel technologies.
And I want to ask a bit about humanitarian use devices and
how it has worked in banning profits or limiting profits on the
sale of these devices.
Given those three areas, let me ask some questions and try
to get through maybe three questions, if we can. And I
apologize for taking half your time with the set-up here.
How can the FDA do a better job of working with the
industry to answer questions, make the review process more
predictable, and restore trust between the FDA and the
industry, because we know that's been a problem?
Commissioner Hamburg. It's so important, and it's something
that we are very actively engaged in. And, of course, the MDUFA
negotiations give us a chance to work with industry to lay out
a set of critical issues and concerns and priorities for
action.
Certainly, Dr. Jeff Shuren, who is with me and who is the
director of the Center for Devices and Radiologic Health, and
myself and other leaders of the FDA are trying very hard to
reach out, to listen to, learn from and work with members of
industry. In the last 10 days, I've actually been in Boston,
California, and Cleveland meeting with leadership, CEOs of the
device companies and entrepreneurs involved in the device
industry. I haven't yet been to your State to do that, but I'll
put that on my list.
Senator Franken. We're the home of medical----
Commissioner Hamburg. I know. But Dr. Shuren, I know, has
spent a lot of time, and----
Senator Franken. And I appreciate that, by the way.
Commissioner Hamburg [continuing]. We've organized both
formal and informal town hall meetings in order to facilitate
these kinds of exchanges. And as we were developing, doing our
internal review of the 510(k) process, also a lot of outreach
to get feedback on our recommendations before we came out with
our action steps.
There are some critical areas that will make a difference
that we are working on and want to strengthen, communication in
terms of both formal and informal mechanisms for sponsors to
come in and meet with us, to ask questions, to get feedback in
an ongoing way, because we know that early engagement,
continuing engagement helps to smooth the process toward a
successful outcome.
Being able to provide more guidance is really key, and it
makes a difference, adding clarity to what our expectations are
and giving industry the opportunity, as the guidances are being
shaped, because we always start with draft guidances, to have
input in the process as well.
I think that we have just recently put out some critical
guidances in that regard.
The ability for us to really make sure also that our own
staff are adequately trained and that we are as explicit as
possible about our standards is another important aspect of
what we're working on with new training, certification
programs, and we're eager to work with AdvaMed and others
representing the device industry, and companies on what is
expected and how they can improve their ability to comply with
our standards.
Senator Franken. Submissions.
Commissioner Hamburg. And we're really trying to reach out
to small business as well, because we recognize that,
especially in the device industry, so many of the companies are
small. Many, many of the companies, a very high percentage,
have never put forward an application to the FDA before, and we
recognize that it's a complex landscape to navigate, and we're
trying to build in some new points of contact and some new
programs to make FDA more transparent in that regard.
Senator Franken. Thank you. My time is up. I'll submit some
questions for the record.
Mr. Chairman, going forward, I plan to work on the three
policy issues that I touched on in my questions, communication
between the FDA and the industry, unnecessarily restrictive
conflict of interest rules, and the profit cap on humanitarian
use devices, and I hope we can work together to address these
issues.
The Chairman. I assure you, Senator Franken, I appreciate
your leadership on these issues, and I'll be pleased to work
with you to move this forward.
Senator Franken. Thank you so much. Thank you, Mr.
Chairman.
The Chairman. Thank you.
Senator Burr.
Statement of Senator Burr
Senator Burr. Dr. Hamburg, welcome.
Commissioner Hamburg. Thank you.
Senator Burr. Thank you for what you do, and thank you for
being here with us today.
Do you have any idea how many drugs and devices bypass the
American market now and seek approvals in Europe, Asia, and
South America because of time delays or the cost of approval in
the United States?
Commissioner Hamburg. Actually, on the drug side, we are--
--
Senator Burr. You're still the 800-pound gorilla in the
room, but does it concern you that manufacturers make decisions
not to seek approval in the United States for ground-breaking
therapeutics?
Commissioner Hamburg. I'm very concerned about the strength
of the U.S. industry, the ability of American companies to
deliver the products, drugs and devices that the American
people need, and that we have a strong----
Senator Burr. Is it alarming to you that American companies
would choose not to seek American approval for breakthroughs
that they have?
Commissioner Hamburg. It is important to step back and look
at where we are and to strengthen the programs to make sure
that we maintain our pre-eminence. On the drug side, as I said,
we are the first to approve drugs in more than 50 percent of
the cases. So Americans are getting those new products sooner.
Senator Burr. Tell me why we should reauthorize user fees
for pharmaceuticals and devices when, in the case of devices,
the length of time has gone up since we instituted user fees?
Commissioner Hamburg. This chart, back on your other
question, does speak to the success of the user fee program on
drugs. And really the increase in terms of the new active
substances first launched on the world market really came after
the introduction of PDUFA, and it's very striking, and it's
very, very important, and it matters to patients.
Senator Burr. Well, you had a very long----
Commissioner Hamburg. But there's another chart I was going
to show which gets to your question on medical devices. This is
the average time to decision for the 510(k) process, and the
blue line represents the FDA, and the red line represents the
submitter, and the black line the overall time to decision.
Senator Burr. And charts have a tendency of flipping back
and forth between real days and FDA days. That's something
we've all got to get into to figure it out, but let me move, if
I can, because you were talking about----
Commissioner Hamburg. And I apologize. You were asking both
questions in terms of our comparison with other countries and
the times to review, and I was trying to answer both.
Senator Burr. And I think you've alluded to FDAMA as sort
of the statutory guidelines. It's the blueprint out there right
now. And FDAMA required FDA to eliminate unnecessary burdens
that caused delays. The sections of the statute that capture
that is the least burdensome language. For years, FDA included
least burdensome in the guidance and the letters. Yet in 2009,
least burdensome disappeared, no notification. Least burdensome
just went away. An internal document from the FDA dated
November 23, 2009 called for the removal of the least
burdensome language to avoid confusion and inconsistency in its
application.
Now, doesn't this memo basically say that the FDA applied
these provisions in an unpredictable and inconsistent manner?
Commissioner Hamburg. I think we are trying very hard on
both the drug side and the device side to make our regulatory
pathways as transparent, as predictable, and as consistent as
possible. If you look at what we're trying to do on the device
side, the 25 recommendations following our internal review of
the 510(k) process----
Senator Burr. But is it the agency's policy to ignore the
statute in the law?
Commissioner Hamburg. Pardon me?
Senator Burr. Is it the agency's policy to ignore the
statute in the law?
Commissioner Hamburg. We are striving to be as least
burdensome as possible and really trying to look hard at our
business processes.
Senator Burr. But if it's in the law, why would you take it
out of the process? Why would you take it out of the guidance?
Commissioner Hamburg. You know, I'm not sure what document
you're looking at.
Senator Burr. It's a document dated November 23d.
Commissioner Hamburg. But we absolutely adhere to the least
burdensome context for what we do, and as I said, we're trying
very hard to----
Senator Burr. Let me read from the document, if I can.
``The approach the Center has followed in including
least burdensome language in guidance documents is not
consistent with either the 2002 guidance or the GGP
Manual. To avoid further confusion and inconsistency,
from the date of this memorandum forward, draft and
final guidance should no longer include standard least
burdensome paragraphs,''
which is the statute of the law that we follow least
burdensome.
Commissioner Hamburg. My sense is that it was a removal of
certain boilerplate language, but that it is a fundamental
concept and commitment that we have, and in the work that we're
doing on both the device side and the drug side, we are
striving to achieve that. We're trying to achieve it in both
looking at our business processes and----
Senator Burr. But your own internal document states that
there was inconsistency and confusion is the reason that the
language is no longer there, yet least burdensome was put into
the statute of the law to try to make sure that we didn't move
the goalposts on applicants that were in the process for
approval.
Now, my time has run out. Mr. Chairman, I'll stick around
for as long as Dr. Hamburg will. Thank you.
The Chairman. Thank you, Senator Burr.
Now we go to Senator Hagan.
Statement of Senator Hagan
Senator Hagan. Dr. Hamburg, thank you for being here today
and for your work at the FDA.
Just to follow up a little bit on the medical device, we
are hearing that companies are taking research overseas, and
taking jobs and closing down companies in North Carolina
because of some of the unpredictability. And in particular, I'm
hearing from medical device companies about the review of the
510(k) products. It's become particularly burdensome, causing
product approval delays and the frustration for the
manufacturers, providers, and obviously the patients. That's
what we're most concerned about. And so anything that would
delay the review process really concerns me at this time of
economic job losses, of losing any jobs overseas, and then the
inability to innovate.
The industry plays an important part in our economic
recovery, and I want to support their growth. I also continue
to hear from constituent companies that the FDA's medical
device review process is pretty unpredictable.
How can we improve the situation? I think you talked about
that in your opening remarks. And what I'm particularly
interested in is that I've heard concerns that the FDA is
stopping the clock. The clock stops when questions about more
data are brought forward. And I certainly understand that the
FDA is not responsible for how long it takes a company to
respond, but I think the FDA does share responsibility in the
delay when the agency requests additional data that warrants
significant and additional financial and time burdens.
I know you can't speak about confidential negotiations, but
can you discuss whether the agency has thought about providing
early feedback to companies prior to application submissions or
adjusting how the FDA measures time in relation to the user fee
goals?
Commissioner Hamburg. You have a lot of important questions
embedded there. We are very committed to trying to streamline
the review process and make it easier to navigate for
companies, and importantly for patients, get products to them
as quickly and efficiently as possible while, of course,
safeguarding the important standards for safety and
effectiveness.
I do think that in the MDUFA process we have an opportunity
to really act in some key areas that will provide us with the
necessary tools and resources to make significant strides
forward in key areas, whether it's in terms of the review
teams, their training, their management oversight, the ability
to provide guidances in critical areas to industry, the ability
to ensure consistency of decisionmaking with the creation and
support of our Center Scientific Council, a number of things
that I think we clearly agree with industry are very, very
important to the effectiveness and performance of the program,
and we're embarked on many of them. We need to strengthen and
extend, and I think we have an opportunity if we can clarify
some of the needs and priorities, and the sources of stable
funding as well.
That said, I think it is important to look at that at the
present time we are meeting most of the agreed-on goals with
industry. Ninety percent of the 510(k) applications that come
before us are reviewed within 90 days, 98 percent within 150
days. That was the agreed-on targets in terms of the FDA time
with industry.
But what really matters, as you point out, is the time it
takes to get that product to market, and that is longer. I had
a chart that I was showing earlier that shows an upward trend
in terms of the time of the submitter as part of the
contribution to the overall trend.
We're committed to working on our part. We're also
committed to working with industry to reduce the time of their
contribution to the overall time to decision. AdvaMed is moving
forward in working with industry to train them to FDA standards
so that some of the issues with poor quality submissions can be
addressed. Earlier communication, more frequent communication
can also help to bring that line down.
Senator Hagan. When the clock stops, that's when we're
hearing so much concern.
Commissioner Hamburg. And I think the better the
communication and the more clarity in terms of guidance and
communication, the less frequently we'll have to stop the
clock.
We also took a very serious look at whether or not our
reviewers were asking for data that was appropriate to do the
responsible review.
Senator Hagan. That's what we're hearing a lot.
Commissioner Hamburg. And we found that in some instances
they were not. It wasn't a huge amount of the time, but more
often than is acceptable, and that's why we're implementing
these reviewer certification programs and training programs,
and the oversight of the Center Scientific Council that will
review and sign off on data requests and the scientific issues
in terms of an application and its adequacy.
I think we are moving forward in some key ways that will
make a difference, and I hope that as we move into the next
stage of MDUFA we can really strengthen these programs and
activities that will make a difference.
Senator Hagan. My time is out. But just one thing--and I
would like to submit some questions for the record.
And that is that I'm concerned that there's a proposal to
regulate laboratory diagnostic tests as medical devices, and
they're already regulated under CLIA, and I worry about the
impact of the additional and duplicated requirements that the
industry would have to meet under a second regulatory regime.
So that's another huge concern out there, and maybe if we have
time to come back around for a second round, we can go over
that issue. Thank you.
The Chairman. Thank you, Senator Hagan.
Senator Bennet is gone.
Senator Murray.
Statement of Senator Murray
Senator Murray. Thank you very much, Mr. Chairman.
Dr. Hamburg, welcome. I appreciate you coming and all of
the work that you and your agency are doing. It is always
challenging to balance getting everything approved in a timely
manner while making sure that the public is safe. I appreciate
the job you do.
One issue that I wanted to raise this morning that is of
concern to me is the safety and effectiveness of drugs used in
children.
We have passed two laws, the Best Pharmaceuticals for
Children Act and the Pediatric Research Equity Act, championed
by Senator Dodd and Senator Clinton. They have both
dramatically increased the amount of information that we now
have available on drugs for children. Studies conducted under
those two laws have led to almost 400 pediatric label changes,
and those two laws have historically been reauthorized along
with the Prescription Drug User Fee Act. I hope we can further
strengthen these laws in 2012.
Additionally, I wanted to direct you to a GAO report
published in May which found that 130 additional products have
been studied in children since these laws were last
reauthorized in 2007, and as a result, all 130 products were
revised with important pediatric information.
Can you just take a few minutes and tell us about the
importance of these laws and whether you support
reauthorization?
Commissioner Hamburg. These laws, as you point out, have
been very, very important and have really in many ways changed
the landscape in terms of deepening our understanding about the
appropriate use of products, drugs in pediatric populations and
recognizing that children are not just small adults but there
are differences in how they respond to various treatments, and
we need to understand them, and we need to make it clear to
patients and their health care providers about that appropriate
use through labeling changes.
Senator Murray. So would you support their reauthorization?
Commissioner Hamburg. We strongly support, we're very
enthusiastic about what has been accomplished since these laws
were enacted, want to work with you to make sure they are
reauthorized and can remain vibrant and active going forward.
Senator Murray. OK, very good. I appreciate that response.
Mr. Chairman, I look forward to working with you to make
sure those bills are reauthorized as we move forward, too. I
think that's really important.
I do have several other questions I'm going to have to
submit for the record.
I have to get to another hearing. But, Dr. Hamburg, thank
you for your work. I appreciate it.
Commissioner Hamburg. Thank you.
The Chairman. Thank you, Senator Murray.
Senator Mikulski.
Statement of Senator Mikulski
Senator Mikulski. Thank you very much, Mr. Chairman.
Good morning, Dr. Hamburg.
Commissioner Hamburg. Good morning.
Senator Mikulski. I'm so glad to see you, and I welcome you
with the same enthusiasm that I feel with pride that the FDA is
located in my State, all the wonderful people, thousands, over
3,000 who get up every single day to think about how they can
help with our drug and medical devices to make sure that we're
saving lives, improving lives, and creating jobs.
I really would like to welcome the committee to go out to
FDA, that we actually take a field walk-around where we go to
see what FDA actually does and the wonderful people who work
there, and the talent that we have that we have to keep, that
we have to motivate, energize and so on. So often blaming the
Federal employees for the problems of Federal policy I think is
a lesson we should learn.
I want to thank you for your self-evaluation of the agency
that you presented here today. But I want our colleagues to
realize who works at FDA--M.D.s, Ph.D.s. If you just take the
word ``bio,'' bioengineering, biostatisticians, computational
biology, these are people who, if they left FDA, could go to
Wall Street and make three to five times as much money managing
money rather than managing this process.
We need to get real. We need to have the right policies,
the right user fees, and the right way so that we can work,
because for we in Maryland and we in America, life science is
our jobs. It is our jobs, the medical devices we implement and
the drugs that we do.
When I think of my own mother, who passed away in 1996 from
the ravages of diabetes, she had the best that medicine,
Medicare could offer. And now, what would she have now that she
didn't have then? Better home testing medical devices to be
able to provide her with the biofeedback to better monitor
herself. She had three drugs to pick from. There are now 300
drugs to pick from. Her life would have been better, it would
have been longer, and we would have created jobs to do that.
This is why I'm so passionate about FDA and what we need to
do.
Having said that, let me go to your very meaty testimony.
You raised the issues related to innovation. You have a series
of recommendations. As you can see here today, there is an
inherent tension between innovation and regulation, and we
shouldn't have to pick one side or the other, regulation for
safety first, efficacy as crucial for getting value for our
dollar.
What can you see that we need to do in PDUFA to make sure
we promote adequate regulation but we don't stifle innovation?
So this is the underpinnings of some of the questions. Could
you elaborate on that, and what do you need us to seriously
think about?
Commissioner Hamburg. I think you're absolutely right. We
need to marry safety and innovation. We need to make sure that
we are really capturing all the advances in science and
technology today into real-world products for people. I think
there are a number of things that are underway and a number of
elements in the PDUFA V negotiation package that will help us
to strengthen those activities.
One is critically building out some of these scientific
capabilities so that we can really use science to target our
therapies, to identify where are the critical opportunities in
terms of the patterns of disease, how can we do clinical trials
that are meaningful but shorter and more cost-effective, how
can we look out across the whole life cycle of a drug to ensure
safety and effectiveness by using data mining and monitoring
available information in the real world.
Senator Mikulski. Dr. Hamburg, if you could withhold a
minute. In your written testimony, you talk about how you want
to streamline the regulatory process but make sure we ensure
safety.
Commissioner Hamburg. Right.
Senator Mikulski. It's an obsession with us and I think
what separates Western democracies from those who just want to
make products. You have several recommendations here. Were they
supported by the private sector, and have you begun to
implement them?
I'm talking about the innovation, pathway to public-private
partnerships.
Commissioner Hamburg. The innovation pathway--yes, very
much so.
Senator Mikulski. Scanning.
Commissioner Hamburg. I think one of the areas that's been
very exciting is the opportunity through public-private
partnerships to really address these critical issues in terms
of the gaps in science and how to build on them to really spur
innovation, and I met recently with R&D directors from some of
the major pharmaceutical companies, and they really see this as
a critical need from their perspective, and we see it as a
critical need from our perspective in terms of having the tools
to apply to the process.
I think that in terms of the device program, it's very,
very important that we have a flexible regulatory process that
recognizes that innovation is so dynamic in that area, and we
need to be able to really support industry as it develops an
idea and tests it and puts it into the marketplace, and
continuing to monitor it.
As innovation occurs going forward, it requires that we
have adequate support for science within FDA in terms of
reviewers who understand the complexity of the products that
are coming before us and have the access to external experts
that they need to help enable the review process that will
support these innovative products from----
Senator Mikulski. That's very helpful, and I don't mean to
interrupt. My time is up because I wanted to get in my comments
about FDA.
Also, you share with us the private sector's views and
recommendations on just how to improve the process, from drug
review to regulatory science to others, benefit/risk
assessment. Have you incorporated these in the recommendations
for the committee for reform and refreshing?
There's no doubt when we look at PDUFA, we've got to
refresh it, reform it, re-energize it, but also keep on the
right track for the balance between innovation and industry. So
where are you on these private sector regs?
Commissioner Hamburg. These are the elements, the seven
categories of enhancements that were agreed to with industry as
part of the PDUFA V negotiations. There was enormous enthusiasm
and support for these activities. I would say that that
negotiation process was very constructive and forward leaning,
and we do think that these elements will really strengthen our
programs and activities and our ability to deliver.
Senator Mikulski. Senator Harkin is giving me the tap. I
got it.
Senator Harkin, I really am serious about my invitation to
the committee to come out and really see FDA, because when you
look at who is around the table, our economies in our State
really rest on it, sir. Baltimore, our largest employer was
Bethlehem Steel. Now our largest employer is Johns Hopkins. And
one of which is because of NIH, but also the new products for
FDA. Let's go out and actually see what they do, and let's work
together. Our economy and our people depend on it.
Commissioner Hamburg. We would welcome you, and we did host
an event for congressional staff. I think it was very
successful and useful, and I look forward to hosting all of
you.
The Chairman. Senator Mikulski, I'll take you up on that
sometime this fall if we can find a good day to do it on.
Senator Hatch.
Statement of Senator Hatch
Senator Hatch. Thank you, Mr. Chairman. I want to
compliment my colleague from Maryland. We've worked together
very strongly on these issues.
I think a great deal of her, and I also think a great deal
of you, Dr. Hamburg.
Commissioner Hamburg. Thank you.
Senator Hatch. In fact, I even like the people in the first
row.
[Laughter.]
I just wish you'd be a little less risk-averse, because I
think I would like to see our medical device regulator start to
match what Europe does. I think we're way behind as far as I
can see. Now, I'd be happy to be convinced otherwise.
This is a great agency. It handles a tremendous amount of
commerce in this country. In fact, it's almost impossible to
handle all that you've been called upon to do, but you can do
it. And I think you should call on us to help where we can.
It's clear that in the area of medical devices, we're
losing ground to other countries, in part due to the increasing
difficulty in getting new products approved by the FDA in a
timely and efficient way. For complex and innovative devices, a
whole series of studies have shown a device lag, and every
device executive I talk to is saying that they are moving
clinical trials for first product introductions overseas
because of the challenges they face with FDA.
I've had some medical device manufacturers show me how the
approvals in Europe are so much faster than here and, frankly,
people have benefited from those approvals and those devices in
ways that Americans have not, and I would like to see that
change.
In fact, I read in a recent article in the Cleveland Plain
Dealer that you acknowledge that FDA has played a role in the
national decline in medical product innovation, adding that you
felt much of the criticism of the agency was ``deserved.''
Let me just ask you this. What are you doing to get us at
least back to where we were several years ago in terms of speed
and consistency of review? And how are you attracting
manufacturers to come to and remain in the United States? I
think we're losing a number of them because of some of these
difficulties that I've been raising.
Commissioner Hamburg. Let me first thank you, Senator
Hatch, for all your support over so many years and, of course,
the great work that you and Senator Mikulski have done to
support the White Oak facility and other important aspects of
our work.
Let me then address the question about U.S. approvals
versus Europe, because I think it is important to clarify.
A recent industry study that has been cited already did
show that for lower-risk devices that don't require clinical
data, which represents about 80 percent of the devices we
review, that the United States is, in fact, as fast or faster
than Europe in bringing those products to market. For the
higher-risk--and this chart does speak to that. For the higher-
risk devices, we are slower than Europe, but it's important to
recognize that we have a different standard, a different
regulatory framework, and in Europe they don't require safety
and effectiveness like we do. They require safety and
performance.
And what that means in the real world is that, for example,
for a condition like atrial fibrillation, which is an irregular
beating of the heart that can be associated with serious
medical complications, including stroke, that for a technique
called ablation that tries to disrupt abnormal electrical
pathways that cause the irregular beating, you can use a tool
to basically cut or burn the tissue. And in the United States,
we have to show that the device actually has a benefit for
patients in terms of a positive impact on this underlying
condition. In Europe they just have to show that it affects the
heart tissue.
That is a different standard, and I think----
Senator Hatch. I understand that. Would it be better for us
to switch to the European performance language?
Commissioner Hamburg. I think it is very, very important. I
think the American people really count on----
Senator Hatch. Let's get some answers.
Commissioner Hamburg [continuing]. The fact that a medical
device that they will use or a family member will use that may
be implanted into them for a very long period of time, that not
only will it be safe and effective, they count on that and that
it will actually benefit them in terms of the intended use, and
the European requirement is different.
I think it's a very different model where the sponsor pays
a private entity, a so-called notified body, to review the
product. These are not bodies that are under the oversight of
any authority. They have different expertise and
qualifications, and the information and data that goes into the
decisionmaking is not made available to the public.
So, I think, the device industry leadership agrees that we
should not change the standards for medical device approval in
this country. AdvaMed recently put out a press release speaking
to that. But I think what we can and must do is work together
to make sure that we have the most streamlined and modern
regulatory systems possible. At the end of the day, absolute
speed is probably not the only and ultimate criteria to ensure
safe and effective products.
Senator Hatch. I'd be the first to agree with that. Just
the latter part of that question about attracting business to
this country, could you elaborate on that for a minute?
Commissioner Hamburg. That is a very, very important----
Senator Hatch. It really is.
Commissioner Hamburg [continuing]. Issue, and we are----
Senator Hatch. I'm on your side.
Commissioner Hamburg [continuing]. Working very hard. No,
and I think----
Senator Hatch. I'd like to help you. But I really think
we're pretty slow. But go ahead, attracting----
Commissioner Hamburg. I think we have a contribution to
make in achieving that goal that's very, very real. It's also a
more complex ecosystem with economic policies and issues around
the costs of labor in other countries versus the United States.
But in terms of the FDA component, that is why we are so
committed to making our regulatory pathways as clear,
consistent, and predictable as possible, as streamlined and
modern as possible, trying to develop guidances to address some
of the key areas of concern for American manufacturers such as
clinical trials, which are often cheaper and easier to do
overseas. We're soon going to be putting out new guidance to
encourage earlier in-human study of medical devices that will,
I think, provide an important incentive to doing those studies
here in the United States.
And I think that through the MDUFA process, we have the
opportunity to really focus and act on some of the key areas
that will help to make our medical device review systems as
timely and efficient and responsive to the needs of patients
and innovation as possible.
Senator Hatch. I want you to know I'm interested in all the
UFA processes, not just MDUFA.
But I want to thank the Chairman for his leadership in
these areas and, of course, the Ranking Member as well, both
are terrific as far as I'm concerned. And I want to thank you,
doctor.
Commissioner Hamburg. Thank you.
Senator Hatch. Appreciate you.
The Chairman. Thank you very much, Senator Hatch.
Senator Hatch. I'll submit my questions, further questions.
The Chairman. OK. Thank you, Senator Hatch.
Senator Merkley.
Statement of Senator Merkley
Senator Merkley. Thank you very much, Mr. Chair.
It's a pleasure to have you here, Dr. Hamburg. I wanted to
start with an article that came out yesterday regarding a
report that's anticipated tomorrow. This is a report from the
Institute of Medicine that was charged with analyzing
regulatory proposals related to medical equipment like hip
implants, hospital pumps and defibrillators.
And apparently, even before it's out, it's becoming quite a
controversial study. Would you mind commenting on what are the
issues here? Is there a problem with the balance of the panel?
Is it already known what the report will say and people simply
disagree with it, so on and so forth? What's going on here?
Commissioner Hamburg. The Institute of Medicine is a branch
of the National Academy of Sciences, and of course the National
Academy of Sciences was actually begun by Abraham Lincoln many,
many years ago to help provide scientific consultation and
expertise to government as important decisions are made.
We actually asked the Institute of Medicine to put together
a committee and do a study about important issues involving the
510(k) regulatory process, which is the largest component of
our medical device review activities and so important.
They put together a committee, as they always do. We as the
requesting agency have no input into the committee composition,
but they have standards and practices about diversity and
conflict of interest on their committees. They will be putting
out a report. That report, as I mentioned earlier, will provide
us with recommendations, which will only be recommendations,
and we will review them and we will get feedback in terms of if
we want to pursue aspects of those recommendations.
Senator Merkley. But just cutting to the chase, is there
something anticipated that is really quite controversial?
Commissioner Hamburg. I think there was concern expressed
by some components of the device industry about whether their
perspective was adequately represented on the committee. I
think that various lawyers have looked at that and feel that
the composition of the committee is sufficiently diverse and
containing----
Senator Merkley. My impression is that people are upset
because they are disagreeing with what they think is going to
be in the report tomorrow. I don't know if there was a pre-
announcement or a draft announcement, but what is the heart of
the actual policy issue that is being wrestled with here?
Commissioner Hamburg. I think the heart of the policy issue
is the adequacy and appropriateness of the 510(k) process,
whether it achieves its dual goals of assuring safety and
efficacy of products and the timely introduction of innovative
products into the marketplace. I have been briefed but have not
had a chance to actually read the report, which is embargoed
until tomorrow.
But I think that it obviously will be speaking to very
important issues, and I think that the concerns reflected in
that newspaper article have to do with whether the committee
was properly constituted.
Senator Merkley. OK. Let me switch gears here, then. Thank
you.
Sometimes problems develop after a product is introduced
that weren't caught in the clinical trials. Can you address how
well the MedWatch system is publicized and being used by
consumers? Is it providing valuable feedback? Could it be
improved?
Commissioner Hamburg. I think we need to strengthen many
components of our postmarket surveillance activities, as you
suggest. We often learn about safety concerns in much greater
detail once the products are out in the marketplace being used,
not just by a limited number of patients who are involved in
the early clinical studies but by thousands, hundreds of
thousands, millions of patients and individuals who may have
other underlying medical conditions or are taking other drugs
that may also affect the safety and safe use of those products.
So we do need to continue to strengthen the systems for
adverse event reporting. We also, in large part due to efforts
by Congress, through FDAA in 2007, are strengthening our
broader activities and programs in the postmarket period,
including our ability to really target in on emerging safety
concerns through changes in labeling, changes in data
collection to further drill down and understand those problems,
and in mining existing databases and creating new databases to
inform our decisionmaking.
Senator Merkley. A last brief question, or at least I'll
need a brief response.
Commissioner Hamburg. Sorry.
Senator Merkley. And that is, given new forms of
advertising, Internet and social media and so forth, and the
types of cautions that are normally embedded in prescription
drug and medical device advertising, are those presenting new
issues that you're having to wrestle with?
Commissioner Hamburg. Certainly the age of the Internet has
created vast new challenges for us in terms of monitoring what
information is out there about products in terms of advertising
and its accuracy; and also products that are, in fact, being
advertised for sale that are fraudulent or counterfeit. And we
are working very hard--it's a domestic issue; it's also an
international issue, because many of these Web sites are based
overseas--to try to get a better handle on the scope of the
problem and to identify solutions that will really work. But
it's a huge, huge challenge.
Senator Merkley. Thank you very much.
Commissioner Hamburg. Thank you.
The Chairman. Thank you, Senator Merkley.
Senator Bennet.
Statement of Senator Bennet
Senator Bennet. Thank you, Mr. Chairman. Thanks for letting
me go and come back.
And, Dr. Hamburg, thank you so much for being here today.
Commissioner Hamburg. Thank you.
Senator Bennet. I heard the questions at the beginning, the
answers at the beginning, missed some in the middle. But I
wanted to make one observation about the tension that I think
exists around some of these issues.
The mission statement of the FDA is pretty clear that it's
both about the public safety, public health, and also about
driving innovation in our medical device industry, or
supporting innovation maybe is a better way of saying it. The
tension that the folks in my State feel that are in this, doing
this work, this incredibly important work of developing medical
devices, I think is rising as a reflection of the globalization
of the industry, and the concern that a lot of us have is that
we may not own this industry in the 21st century, or that we
may lose it.
One thought that I have is whether we want to consider
changing the mission statement to recognize the global economy
that we're in and the importance to the United States of being
able to drive this, or maybe that's not the right place to do
it, maybe it's somewhere else. But I wonder whether just more
broadly--your efforts are commendable, but are we moving at a
rate of speed that's going to get us to a place where we're
going to be able to compete in real time with the rest of the
world, or not lose the advantage that we have?
Commissioner Hamburg. I certainly share your concerns, and
certainly in terms of my leadership at the FDA and the
orientation of all the extraordinary staff that work with me at
the FDA, we see our mission as doing our very, very best to
assure the safety and effectiveness and quality of the products
that we regulate, but also to help support and facilitate the
translation of opportunities in biomedical research and science
into products that people need, and also to try to provide some
sort of recognition of the need to match unmet public health
needs with opportunities that exist in terms of available
science and technology. And so we are committed to all of those
things.
I have actually created within my office in recent months a
special focus on innovation, trying to support all of the good
ideas, programs and policies that are spread throughout FDA
with a focus on advancing innovation. I've also been trying
very hard to work with my colleagues in government and outside
to really look at what can we, as a nation, do to strengthen
our programs and policies to support innovation, because FDA
plays a critical role, but it also has to do with patents and
IP. It has to do with economic policies and taxes and
incentives. It has to do with reimbursement issues, and it has
to do with making sure that FDA takes a very hard, serious
look, which we are doing, at how can we streamline and
modernize our regulatory systems to make it easier for
companies to work with us and to make sure that those exciting
and promising candidate medical products actually make their
way into the marketplace.
Senator Bennet. I think that's well said, and I think
everything that you said is true. What concerns me when I have
the people come in is because they're the life science
manufacturers or the inventors or entrepreneurs, because their
interaction with the Federal Government generally is the FDA,
they're looking for the FDA to help solve this problem on
competitiveness, or to at least not compromise their ability to
be competitive and stay here in the United States and do the
work, and I feel like I'm having the same conversation year
after year, with respect, because I know you are doing a lot of
this work, having the same conversation year after year, and it
sometimes feels to me as though it's no one's day job, and you
just said it is some people's day job, it's no one's day job to
say how do we hold onto the competitive advantage that we have,
or create more competitive advantage going forward.
And it's not just an FDA issue, as you said, patent issues,
all kinds of things. Whose job is it to think about and to
really implement policies that are going to drive innovation in
the country?
I want you to know that I look forward to working with you
on this to try to support these efforts on behalf of Colorado
and on behalf of the country.
And before my time runs out, we're now at a point where,
just to shift gears for a second, 80 percent of the active
ingredients in our drug supply chain is coming to us from
offshore, and you have acknowledged that as an issue and I
think stated the need for us to work with international
regulatory agencies to make sure that we can stay ahead of the
problem of a compromised drug supply and other issues.
I wonder if you could talk a little bit about what that
will look like and whether we are doing everything we can to
try to inspire international cooperation around that issue.
It's a big surprise to people in Colorado when I tell them
that 80 percent of the active ingredients in their drugs come
from overseas and that we actually have very little in the way
of inspection of those plants, especially in China and other
places, and that we can't always be sure of what's in our
pharmaceuticals.
Commissioner Hamburg. It's such an important problem.
Globalization has really changed the world, and it really
requires that FDA changes the way that we do business. You're
absolutely correct. Today, 80 percent of the active
pharmaceutical ingredients in drugs taken here actually come
from other countries. About 40 percent of the finished drugs
taken here come from other countries. And we need to recognize
that the supply chain for these products has gotten very
complex and much more complicated, with many points along the
way for potential unintentional or intentional contamination,
adulteration, or impacts on quality.
And so we need to really transform. When our agency was
first created, the world looked very different. We need to
transform and we need to move beyond the borders in terms of
how we inspect and ensure quality in products coming into this
country. We need to work much more closely with sister
regulatory authorities to share information, to try to
harmonize standards and approaches, and to actually in some
instances share the workload in terms of inspections. There are
way too many facilities out there for any regulatory authority
to get in and inspect them with the frequency that we would
like. And so we're really developing those kinds of
relationships.
We also have to work in much closer partnership with
industry, who clearly needs to be accountable for the supply
chain of their products, and at the end of the day, through
working together, we need to be able to assure the integrity of
the supply chain and the trust and confidence of the American
people in these products.
We've also now set up offices in many countries around the
world that provide a regional presence for inspections and
activities, working with industry and other stakeholders and
our counterpart regulatory authorities to ensure that our
standards are understood and being met. We're also trying to
work hard with many countries that have less sophisticated
regulatory capabilities than we do to help raise their
standards, which will serve us all.
There's an enormous amount to be done. I know that you've
been taking a very serious look at this, and we welcome the
opportunity to work with you as you examine what kinds of
additional authorities might be needed.
Senator Bennet. I appreciate that, and my time is long
expired. But I want to thank the Chairman and the Ranking
Member for letting me go over for a second.
The authorizing statute for the FDA, as you know, was
written I think in 1938. It was in the 1930s, sometime when the
entire supply chain was domestic, and now I think it's high
time for us to take a look at that.
I also want to let you know that I've asked the biotech and
device guys in Colorado to give me the 9 or 10 pain points that
they really have, and we will get those to you, in an effort to
not have the same conversation next year that we had this year.
And I hope it will be useful to you as you think about this.
Commissioner Hamburg. Yes. I appreciate that. It is very
useful to hear directly from people on the ground what are
their critical issues and perceived barriers and concerns.
Senator Bennet. Thank you, Mr. Chairman.
The Chairman. Thank you, Senator Bennet.
Let's start a second round here.
I just want to say to Senator Bennet, looking at the supply
chain, I had mentioned in my opening remarks that we wanted to
focus today on PDUFA and MDUFA and the reauthorization in that
area, and I said I'm going to have some hearings this fall on
that very subject of the supply chain. I look forward to
working with you.
Senator Bennet. Good. Thank you. I will as well. Thank you.
The Chairman. You know, we all want better devices. We all
want innovation. We all want to know that if we have an injury
or something like that, that there are devices out there that
will permit us to live life to the fullest, and we've made
great strides in that area in this country, in innovation in
devices. I've followed them for years with my work on
disability issues, for example.
But, you know, let's face it, there's a lot of money to be
made in devices. People have gotten immensely rich in this
country because they've innovated, they've invented, they made
a device and got out there, and people have gotten immensely
wealthy in this area. I don't deny that. That's fine. That's
part of the American dream.
But I do want to make sure that we have an agency that is
independent and that is able to withstand the tremendous fire
power of an industry that has a lot of money and obviously
wants the least amount of regulatory oversight. I understand
that. I mean, that is, again, part of the give and take of our
society.
I think it is a gross disservice to many of us who have
been supportive of the industry, as I have been in the past, as
I said, through my work with disability issues over most of my
adult lifetime. I've seen the tremendous help that devices have
provided for people so that they could have a better life. It
does a great disservice to us when an article like this appears
in the New York Times this morning outlining how--I'll just
read the first sentence.
``Allies of the medical device industry are waging an
extraordinary campaign in Washington to discredit a
coming report by one of the country's pre-eminent
scientific groups that examines possible new
regulations on the industry. The scientific group
being''--of course--``the Institute of Medicine, is
scheduled to release a report on Friday that could,''--
that could, I don't know, I haven't seen the report
yet--``that could propose a tougher approval process
for a wide range of devices like hip implants, hospital
pumps external heart defibrillators.''
``The report, commissioned by the Food and Drug
Administration, comes after several well-publicized
recalls in recent years of devices that have failed in
thousands of patients, causing numerous injuries. But a
business group and others have taken the highly unusual
step of making a pre-emptive strike, arguing that the
report is biased. That attack began even before the
study panel finished its review and has intensified in
recent weeks.''
``The challenge to the panel has been led by a Ralph
F. Hall,''--who I don't know--``a professor of law at
the University of Minnesota and a device industry
lawyer. . . . `I could have waited until the report
came out,' Mr. Hall said in an interview. `That seems
intellectually less than satisfactory with me.' ''
Say again? I attack something before it comes out rather
than waiting until it comes out to read it, to analyze it, to
see what the input was? But I attack it before that, and that's
more intellectually satisfactory?
I'm going to ask that this article be made a part of the
record here, since I quoted from it.
[The article referred to may be found in Additional
Material.]
The Chairman. Look, there have been times in the past when
I've seen studies from the Institute of Medicine that I didn't
like because it went against my preconceived beliefs. Well,
then it made me really question my preconceived beliefs.
I say to the device industry, the kind of story that
appeared in the New York Times this morning, and the statements
by Mr. Hall and others do a disservice to your industry,
because the FDA is charged, as you said, Dr. Hamburg, quite
frankly, not only with making sure that products are safe, but
that they are effective, different than what they do in Europe.
I want the FDA to continue that, and I want it to continue to
be an independent agency.
From my standpoint and having been here for so many years,
on both this committee and the Appropriations Committee,
perhaps one of the most unbiased scientifically oriented groups
in this country is the Institute of Medicine. I hope you will
continue to rely upon them, and don't let this kind of stuff
that's coming out here today and other days dissuade you from
that.
I want you to continue to be independent, use the best
science. I know you're going to get pulled from one way and
pulled from the other way. I understand that. This industry is
so important to our country. We don't want it to go overseas.
We want it to stay here. But to take this kind of attitude that
they will not even listen to a report from the IOM and engage
in a reasonable conversation about it but they just attack it
before it comes out, as I said again, not only it does a
disservice to the industry, it does a disservice I think to the
patients and our country.
So having said that, I've used up my time. I didn't even
get to ask a question. But I just wanted to respond on that
issue with the difference between here and Europe. I'll just
take a couple of more seconds.
In Europe, you're right, they just want to know if it
performs as they say, without deciding whether it is effective.
But that's covered later on in their reimbursement systems in
Europe, which is quite different than ours. And since we are
not really changing our form of reimbursement system to be like
Europe's, then we rely upon the FDA to make that decision, is
it effective, does it really lead to good clinical outcomes.
As I said, that's not part of the European system. It's
part of their system later on in the reimbursement side of it.
So that's why our system is different than Europe's.
Thank you very much, Dr. Hamburg, and I'll yield to Senator
Enzi.
Senator Enzi. Thank you, Mr. Chairman. I'll follow up a
little bit on what you said and ask a question.
The last PDUFA law authorized the risk evaluation and
mitigation strategies to speed access to drugs with risk
concerns, but in many cases REMS just ended up slowing down the
review process. Can you fix that process administratively, or
could small statutory fixes help you to effectuate legislative
intent?
Commissioner Hamburg. As you know, REMS, the authority to
pursue that strategy, was given to us in 2007 in FDAA, and we
had to put in place new systems and really sort of develop
strategies that would enable us to better monitor and assess
safety in the postmarket period, which is so important, as
we've talked about.
As we have implemented it, I think it has put new burdens
on FDA and on industry, and we are looking now at ways that we
can really sort of systematize how we do it and look not at a
product-by-product way of implementing some components of it,
but really having guidelines for classes of products. It's an
area where, obviously, the feedback and the exchange with
industry and their experience is helping us to shape how we
organize this program.
And I think that working in that manner, we can move
forward and improve and strengthen REMS. It does give us a set
of important tools that actually give us more confidence on the
front end as we improve promising candidates that may have
safety concerns, that we can continue to monitor and address
those as they go into the marketplace and we learn more about
them.
So I think we can continue to strengthen and streamline the
program. At the moment I, at least, am not aware that there is
any particular need for a legislative fix, but I think we
recognize that the program has been somewhat cumbersome, and it
certainly has put a lot of additional demands on us as we
develop and implement it, and we want to see it really achieve
the goals but not be as complex in its administration and the
workload on both companies and on FDA.
Senator Enzi. Thank you. A June 2011 report from the
Government Accountability Office found that the Device Center
is not overseeing recalls effectively. FDA already has a clear
statutory authority to mandate device recalls, but the average
time it took for FDA to effectuate a Class I recall, which is
the highest risk type of recall, was 516 days. There have been
incidents where individuals were seriously injured or died due
to continued use of defective devices that were supposed to
have been recalled. In one instance, a supposedly recalled
device was re-introduced to the market and patients needed
surgery to remove them. In addition, GAO found that the FDA
does not use recall data to identify systemic safety risks.
What steps are being taken to address those problems?
Commissioner Hamburg. Very, very crucial concern, and we do
need to strengthen our programs and reduce our response times.
There are a number of important activities that are underway,
including the creation of a unique device identifier that will
enable us to more effectively track devices, that health care
providers and the FDA can have much better information about
who has what products, and working with industry when there is
a problem, we can move more swiftly to actually address the
immediate patient needs.
In addition to that kind of activity that will make a
difference from a safety perspective, we have to look at our
systems to make sure that we are responding to emerging
concerns in as timely a way as possible, both in terms of
collecting the safety information, analyzing it, responding to
it and, importantly, acting on it.
Senator Enzi. Thank you. Also referring to the Government
Accountability Office, in 1998 they called for FDA to implement
a series of recommendations to respond to challenges posed by
the globalization of drug manufacturing.
What progress has the agency made on the GAO's longstanding
recommendations on that globalization of drug manufacturing?
Commissioner Hamburg. As I was discussing with Senator
Bennet, this is a huge and growing area of focus, concern, and
activity. We are trying to extend our capabilities in terms of
our foreign inspections, working with counterpart regulatory
authorities to try to share information as well about the
inspections that they are doing and information about supply
chain integrity and the quality of products.
Really, working with industry also because, of course, at
the end of the day their knowledge and accountability around
the supply chains and the manufacturing practices in these
overseas sites is critically important and fundamental to our
shared goal of achieving integrity and safety of the supply
chain.
So we are very, very much focused on this as a priority.
You mentioned I think some interest in the reorganization that
I recently did, and one of the areas was really to try to bring
greater integration of our Office of Regulatory Affairs
activities, which is out in the field doing inspections and
compliance activities, with our Office of International
Programs so that we can really use our resources in the most
coordinated way possible and really focus on strategies that
take into account risk, risk of certain types of products, risk
in terms of past history of certain products or manufacturers,
and really within the realm of possibility enables us to engage
all of the important partners and really use all the best
possible information, wherever it comes from, to inform our
activities.
Senator Enzi. Thank you. My time is up, but I'll have a
followup question. I'll send that in writing.
Commissioner Hamburg. Thank you.
The Chairman. Thank you, Senator Enzi.
Senator Burr.
Senator Burr. Dr. Hamburg, on the question of the IOM
report, if the IOM report on 510(k)s triggers a change in
process, do you commit to make sure that that process is a
notice and comment rulemaking process?
Commissioner Hamburg. Oh, absolutely. We would view their
recommendations as just that, recommendations, and we would
review them internally and seek the perspective of key
stakeholders on those recommendations, and anything that we
would do that would be a permanent action coming out of that
report and those recommendations would be done in an open and
transparent way in notice and comment.
Senator Burr. Let me stay on 510(k)s, if I can. I heard you
say to Senator Merkley that the 510(k) process looks at safety
and effectiveness. Did I hear that correctly?
Commissioner Hamburg. Through the 510(k) process we are
trying to assess safety and effectiveness, yes.
Senator Burr. In reality, the process for 510(k) is
substantially equivalent. Now, if FDA has made a shift to an
assessment of safety and efficacy on 510(k)s, this would be an
earth-changing move.
Commissioner Hamburg. It's clearly a different process than
when you talk about the drug evaluation process and the way
that we look at data and require information to demonstrate
safety and effectiveness.
We're looking at predicates, and we're looking at a
different model. But at the end of the day, the goal is to
support the assessment of safety and effectiveness of that
product.
Senator Burr. Let me just say the statute that's applicable
here is substantially equivalent. That is the process for
510(k) approval. Are you telling me that's not the threshold?
Commissioner Hamburg. That is the criteria. What I'm saying
is that the goal is to make sure that devices that are
reviewed----
Senator Burr. So if you determine that it's substantially
equivalent but you feel that it doesn't meet safety and
efficacy, you're not going to approve the 510(k)s?
Commissioner Hamburg. It's a different model of regulation,
as I said, from the drugs, and it does build on track records
of prior products.
Senator Burr. I'll certainly follow-up on this with
additional questions.
But I would question whether you've got the authority
without a change in rules to do exactly what you've stated. And
if it does, then it may explain a lot as to why there has been
an increase in the time that it takes for device approval.
Has the increase in fees resulted in fewer review cycles
per submission compared to previous user fee agreements on
devices?
Commissioner Hamburg. On devices, unfortunately, the review
cycle has increased somewhat over time, and it's something that
we're focused on and we want to bring down, and we think that
by working together with industry to try to both address the
issues within FDA that we've talked about and the issues around
the quality of applications and response to information
requests from FDA, that we can continue to move in the
direction of bringing those review cycles down.
Senator Burr. Industry says the FDA is moving the goal
posts. The FDA says that this whole process is the result of
poor quality 510(k) applications. Do you want to comment on it?
Commissioner Hamburg. I think that's a very stark view of
what is the conversation. I think that we recognize that it's a
combination of factors. FDA has a role to play, and that's why
we have undertaken this fairly self-critical internal review
and made recommendations for problems that have been identified
that we can act on.
But it is the case that the delays in the time of getting a
new product to market do also reflect the time taken by the
submitter, whether it's because the quality of the application
wasn't adequate and we've had to have a lot of back and forth
to get the information that we need, or because in some
instances we have asked for information that, in fact, wasn't
necessary.
We need to make the overall time as short as it needs to be
to achieve the goals of the review, which is to make sure that
we understand the nature of the product and its risks and
benefits in terms of its use for a given medical condition.
Senator Burr. You're in the middle of negotiating the
device user fees. Would you consider a new structure with the
device user fees where the industry would pay at different
intervals based upon FDA performance?
Commissioner Hamburg. Right now the model does really focus
on FDA review time. I think what you're saying is would we look
at it in terms of the overall performance of the system.
Senator Burr. If the FDA doesn't perform, they don't pay. I
mean, the whole user fee foundation was built on if you supply
us this money, we will become more efficient at what we do,
which one would assume that from all the conversations I heard
today--increased communication, less confusion, clearer
guidelines--that that would all be incorporated so that the FDA
would actually meet and exceed what the expectations were of
the companies and the industries that were paying the fees.
Now, were I in the industry, I would be very reluctant to
come to the table and talk about even reauthorizing the fees
because of the performance that I've seen. Dr. Coburn and I
have asked the GAO to examine the performance goals so that
Congress can fully be informed when we consider the user fee
reauthorizations, and I look forward to reviewing those GAO
recommendations because it's an independent assessment of how
well the industry is meeting the performance goals and the data
on these numbers. The industry says one thing, the FDA says
another. GAO can now sort this out so that whether it's Senator
Harkin or Senator Hagan or Senator Enzi or Senator Burr, that
we can look at it and determine did you meet the performance
goals or didn't you.
Commissioner Hamburg. I can assure you that we track our
performance on the existing MDUFA goals, and in fact those
goals were negotiated with industry, as you know. And at the
present time, we are meeting, in the 510(k) process, 95 percent
of the goals.
I think the larger concern, which is one that we share, is
are we doing an adequate job getting products to market as
quickly as possible, and that involves both the time taken by
the submitter during the process and the time taken by FDA.
The MDUFA goals that were negotiated with industry only do
focus on that FDA component. I think we have a commitment to
working with industry, whether it's part of the MDUFA
negotiations or it's part of our overall work as the regulator
of medical devices, to doing everything that we can to bring
down that overall time so that we can deliver important
products to patients in as timely a way as possible, but with
adherence to the standards that we all agree really matter.
Senator Burr. The Chairman has been gracious to me, and I
will have one more round, Mr. Chairman, just to put you on
notice. But I want to ask this because it's applicable to the
conversation we were just on.
Of the applications counted toward meeting the performance
goals in your chart, what percentage are either approval or
denial letters?
Commissioner Hamburg. Which chart are you referring to?
Senator Burr. I think it's the one on page 10 of your
testimony. I think that's one that your staff has diligently
put up every time we've gotten on devices, but I can't read it
from here because of the light.
But of those applications counted toward performance goals
in the chart, what percentage are actually approval or denial
letters versus----
Commissioner Hamburg. First of all, I have to confess, I'm
not sure what chart you're referring to. But I also think that
in terms of the level of detail of your question, it would be
best if we could get back to you.
Senator Burr. Would you answer that for the record for me?
Commissioner Hamburg. I absolutely will, sir.
Senator Burr. Mr. Chairman, you've been gracious, but
please come back to me.
The Chairman. But you have very good questions, Senator
Burr.
Senator Hagan.
Senator Hagan. Thank you, Mr. Chairman.
Once again, Dr. Hamburg, thank you for all of your work and
service in this job. I really do appreciate all the efforts
that you're putting forward.
I did mention about the laboratory diagnostic tests, that I
would like to go back to that question, and I've heard concerns
about the FDA's proposal to regulate these tests as medical
devices.
As you know, LDTs are already regulated under the CLIA, and
a lot of the industry is worried about the additional impact of
duplicating requirements that they would have to meet under a
second regulatory regime, and I'm concerned once again that
this added regulatory process would definitely slow innovation,
which is what we're really looking for here, impeding the
improvements to patient care, as well as job growth that has
come with innovation across this industry.
It is my understanding that the FDA is in the process of
developing guidance to regulate laboratory-developed tests as
medical devices. Where is the FDA in the development of this
guidance?
Commissioner Hamburg. Laboratory-developed tests clearly
are devices. They are diagnostic tests that are often used to
guide clinical treatment of very serious, often life-
threatening diseases. FDA does have the authority to regulate
them historically because of the nature of how these tests were
developed and used, which was all in-house. FDA exercised
enforcement discretion.
But I think given the realities of the world that we're in
today and that these laboratory developed tests are being done
in commercial laboratories and treating patients in facilities
that are widespread, that it is important that there be a
common standard of review and approval for those tests, along
with other comparable diagnostics. We shouldn't have different
standards depending on where the test was developed. We are
going to be putting out several guidances to help the
laboratory-developed test industry understand what will be
expected of them in terms of regulatory oversight. I think it
actually will create for industry a level playing field in
terms of the companies that are involved in LDTs per se, or
diagnostics more broadly.
We are very mindful of the fact that the LDTs are subject
to CLIA regulation. That, of course, looks at very different
things. They don't look at the actual clinical validity of the
laboratory-
developed test. They're looking at aspects of the laboratory
and the credentials of the people that work there, etc. But we
are going to provide guidance to companies about how they can
use the materials that they have to do under the CLIA
regulatory program to support what they need to provide to FDA
so that we don't--so we try to minimize any duplication of
effort under that circumstance.
Senator Hagan. When are these guidance--when will these be
put forward?
Commissioner Hamburg. I think I can tell you quite soon.
They are at somewhat different stages of development and
review, but they will all be moving forward in a timely way.
Senator Hagan. With the effective dates being--I mean, once
you put your guidance forward in the regulatory process, then
they would have to take effect? Is there a timeframe?
Commissioner Hamburg. Draft guidance. It would be draft
guidance. So we'd have the opportunity for----
Senator Hagan. Public comment.
Commissioner Hamburg [continuing]. Public comment and
engagement around the issues as perceived by the various
stakeholders, and we would obviously take that into
consideration as we move toward final guidance.
Senator Hagan. I know we've talked a lot today about the
drugs and the process there. But in North Carolina, we have
about 19,000 biopharmaceutical jobs in our State, and it is
such an important part of our economy, and I want to make sure
we do all we can to invest in this sector and protect and
attract even more jobs.
I've heard from companies that they've experienced,
obviously, what we've been talking about, the delays in their
approvals. But the main concern has been the FDA's issuance of
a complete response letter and the fact that once the FDA
issues this complete response letter, the agency is no longer
bound by any deadline to make the decision on the product. And
the crux of the problem seems to stem from inadequate
communication between the agency and the company at all stages
of the process. So I would just urge you to help improve upon
the efforts to provide frequent, transparent communication with
the companies.
Can you tell me, is the FDA providing early feedback to
companies to ensure that their application submission contains
all the necessary data? And what is the FDA doing to provide
companies with feedback when the agency issues this complete
response letter or doesn't approve the application?
Commissioner Hamburg. I think one piece of good news is
that, as this chart shows, we actually are approving more
things in the first cycle rather than using the complete
response. So you can see that from the early days of PDUFA,
we've gone from 46 percent approval in the first cycle to now
68 percent. And so that is good news, and it means timely
review and approval, and that's for priority MMEs, but similar
trends, not quite as marked, for the non-priority review drugs
that come before us.
In the PDUFA V categories of activity, we do include a
focus on strengthening communication at various stages in the
cycle because that really does matter to sponsors, and we do
know that it makes a real difference, but it of course does
stretch our resources further. So we're very, very happy that
that is a part of the PDUFA V strategy, and we think that if we
can move forward on that, in fact, it will make a real
difference in terms of opportunities to provide more feedback
and to address questions early and in a continuing way.
Senator Hagan. My time has run out. Once again, thank you
very much for your service.
Commissioner Hamburg. Thank you.
The Chairman. Thanks, Senator Hagan.
I have no more questions.
Senator Enzi.
Senator Enzi. I appreciate all the time that Dr. Hamburg
has spent with us. I'll submit some questions in writing and
relinquish my time to Senator Burr.
Senator Burr. Thank you. Thank you, Mr. Chairman. I'll try
to be brief.
Dr. Hamburg, getting back to a conversation you had with
Senator Hatch, in PDUFA we created the opportunity for the FDA
to use outside review for predominantly Class I devices with
accredited institutions that the FDA could exercise who to
accreditate, what the accreditation requirements would be, and
whether it extended out of Class I into some Class II. But the
objective was to try to move things out of the FDA so that we
could stay focused within the FDA with the limited number of
reviewers on the most sensitive and potentially difficult
devices.
In addition to that, part of PDUFA gave the authority for
the FDA to include foreign clinical data in submissions of
applicants. Now, the first one with the devices was never fully
fleshed. The second one has never been used. Do you see an
appropriate use of either one of those options that are current
authorities given to the FDA?
Commissioner Hamburg. We do use data from foreign clinical
trials in our drug review and approval.
Senator Burr. But not to substitute for the U.S. trials you
require. You use it to supplement. Is that correct?
Commissioner Hamburg. We can use them. We often do see a
situation where there's a U.S.-based trial and an international
trial, but we can use foreign clinical trials data.
Senator Burr. I'd love for your staff to highlight any of
that that is appropriate that they can share with me.
Commissioner Hamburg. OK. And we do seek outside expertise
in our device review programs as well, and it's actually one of
the areas that Dr. Shuren has identified as a priority for
strengthening as well, because it is so critical. And as the
world of devices gets so much more complex and scientifically
and technologically advanced, it is, of course, very hard for
FDA to have all of the expertise in-house that's needed to
review products.
Senator Burr. One has to question whether you can have an
accredited institution approve a band-aid versus the FDA have
to be the one to review it and go through it.
Commissioner Hamburg. We don't spend a lot of time
reviewing band-aids.
Senator Burr. Much of your testimony today highlights
certain data points and performance goals reports. However, the
time to market is probably the most important metric for
patients waiting for life-saving products. How would moving
from FDA days to calendar days help to ensure that the review
clock is not skewed and the performance goals truly reflect the
time that it really takes for life-saving products to reach
patients?
Commissioner Hamburg. At the end of the day, I think we all
agree that what really matters, the outcome measure that makes
the difference, is what American consumers can access in the
marketplace. That is our overall goal in terms of the mission
of the agency and what we're trying to accomplish.
I think that there are different strategies in terms of
identifying the performance goals and the metrics to get there
that can be discussed as part of the MDUFA negotiations, and I
think that we want to see a program where industry and FDA are
working together with clearly defined, achievable goals, and
that it has to be a partnership, and that we have to be held
accountable for what we can do, and I think industry also has a
critical role to play whether it's in terms of the quality of
the submissions or the time that they take to respond to our
questions.
We are working very hard to make sure that we have the
proper oversight, the proper review teams, the proper
scientific management structures, that we're asking only for
the data that's appropriate and necessary, that we are
reviewing what comes before us in as timely a way as possible,
that we are seeking the external expertise that we need to be
able to make the right decisions in as timely a way as
possible.
But we also want to work with industry so that that lag in
time in terms of the submitter also declines, and I think
that's very, very important. I think we're committed to doing
that with industry. I think we agree that there are a set of
issues that we need to work on together, that there is a
blueprint for action. We need to really clarify that, and then
we need to make sure that we have the resources and tools to
build on it and make that real.
Senator Burr. Would you be supportive of eliminating FDA
days and going to calendar days?
Commissioner Hamburg. You know, I don't think it's
appropriate for me to step up to the negotiating table. I think
that that's important----
Senator Burr. I'm not asking you to negotiate. I'm asking
you would you be supportive if an initiative, if a legislative
initiative went to eliminate FDA days and switch to calendar
days.
Commissioner Hamburg. I think it is hard for us to be held
completely accountable. If you're talking about trying to
achieve a program that really works, we have to have----
Senator Burr. My intent is not necessarily to hold you
accountable. My intent is that Members of Congress,
policymakers understand how dang long it takes to approve
something, and your charts are all based upon FDA days, and I'd
be willing to bet that less than 10 percent of the Members up
here even understand what FDA days are.
Commissioner Hamburg. But that is what was negotiated with
industry around our performance goals. So that's why we're
speaking to that.
Senator Burr. In defense of my colleagues, we all know what
calendar days are. So do the American people. And you start
talking about FDA days to somebody who's got cancer and waiting
for a therapy to be approved, and this is a very difficult
thing.
I'm increasingly concerned that the agency is not striking
an appropriate risk/benefit balance for patients. The
California Health Care Institute recently reported that FDA is
focused, ``less on the benefits of new products than on
potential risk, and to try to mitigate the risk by demanding
larger, more expensive, and more costly clinical trials.''
In 2007, Congress gave the agency postmarketing risk-
evaluation mitigation strategy, REMS, authority to address
theoretical risk and empower doctors to prescribe the best
medicine for their patients in an attempt to help the agency
strike the risk/benefit balance. I'm concerned that this
authority is not being used appropriately.
We all want safe and effective drugs. But what are you
doing to ensure that there's a balanced approach that does not
create a barrier to new drugs such as drugs to treat diabetes
or obesity, and has the agency considered the possibility that
patients and physicians would be willing to tolerate some level
of risk in order to obtain new alternatives to treat costly
conditions?
Commissioner Hamburg. We always do look at the risk/benefit
balance, and we recognize that patients are willing to take
very significant risks when they face a very serious life-
threatening or debilitating disease. We certainly approve drugs
all the time that have known associated risks. We do look at
what is the risk/benefit balance.
We recently approved a new drug for malignant melanoma, I
believe, that has a very high risk, almost 13 percent risk of
serious autoimmune disorder associated with it, which can, in
fact, even be life-threatening. But the demonstration of
benefit in treating a disease that otherwise has so very
limited treatment options made that risk/benefit equation make
sense.
Another drug that was approved a while back for migraine
headaches comes with a significant set of risks, including
potential cardiovascular problems. But it is because of the
migraine sufferer--it's different than cancer, those headaches
can be so severe and debilitating--that that risk/benefit
equation was taken.
I do think that in the PDUFA V plan that's going to come
before you, we have an opportunity to address risk/benefit in a
more systematic way. Industry and FDA agreed that this is a
very important area, and that as we really build out a
framework for how to systematically look at risk/benefit, we
also need to make sure that the patient perspective is very
much engaged.
One of the categories of focus in PDUFA V is really going
to strengthen our activities in that area and build out a new
program. And on the device side, we're going to be putting out
very soon guidance about how we think about the risk/benefit
equation and recognizing the complexity of the problem and its
importance in terms of making sure that we get products to
people. And you're right that our postmarket surveillance
authorities also give us different tools as we think about risk
and benefit across the life cycle of a product.
Senator Burr. Doctor, let me thank you for being here
today, allowing me to go through three sessions. I know to
answer any question in FDA is difficult, especially when we're
spanning such a timeframe. But I'd like to make one thing
abundantly clear to you and to the chairman.
This committee, as well as one in the House, has the policy
responsibilities for the Food and Drug Administration. No
matter what you negotiate with an industry on user fees, it's
got to pass through Congress under a reauthorization. I've
raised issues today about measurement tools. If in those
agreements there's not something that addresses to my
satisfaction the ability to measure, whether it's devices or
pharmaceuticals, this will be a very slow and laborious
process.
I'm somewhat bewildered that both industries even sat down
and talked about reauthorization given what I looked at and my
judgments of what they have gotten for the money. It's a
disturbing day when I think that the argument is, provide us
more money and we'll do a better job. I don't think that's the
case.
I think in many cases, follow the statutes and the law, and
there's a pathway to either approval or denial. As you know,
I'm intimately familiar with FDAMA. In 1997, I was one of the
authors. And it amazes me, Mr. Chairman, how far we have
strayed from what is the statutory language of the law. I don't
think that's something I'd suggest the committee undertake, but
if we don't have measurement tools to determine whether a fee
system produces a better outcome, then I'm not sure why we
would sign off on it as policymakers, and I wanted to be very
candid with you today, as I did with the chairman.
If we meet the threshold of satisfaction, I'll be the
biggest fan of the agreement. If not, I will do everything to
try to change it to make sure that we've got the measures in
place that are sufficient for me and for others to agree to
sign off on it.
I thank the Chair.
The Chairman. I thank the Senator from North Carolina.
Commissioner Hamburg. Can I briefly respond?
The Chairman. Please.
Commissioner Hamburg. I do feel obliged to respond. I think
that if you look at the PDUFA program, you can really see
dramatic changes in our drug review programs that have been
fostered, enabled by that important legislation and have really
changed review times and have really enabled us to address what
was an early concern about Americans not getting access to
drugs and therapies as early as people in Europe and elsewhere.
We've seen the dramatic shifts as a result of PDUFA. I
think industry would agree that it has made a real difference
having that source of stable and predictable funding and the
ability to identify together key areas of priority for action.
We're at an earlier stage with the MDUFA process, but I think
that we have the opportunity to really transform that review
process as well and to support the industry in its critical
goals.
And so I'm very, very optimistic about what we can achieve
through this reauthorization process, very, very eager to work
with you and others to provide all of the information that we
can.
I think that it is going to be a very productive and
meaningful process, and I welcome the opportunity to be here
today to begin those discussions and to continue to work with
you to achieve the goals that we share of making sure that the
American people have access to safe and effective products that
can make a difference in their lives, in the lives of their
families, and improving the health of our Nation.
The Chairman. Thank you, Dr. Hamburg. And I thank the
Senator from North Carolina.
I have just three or four statements.
Time to market I do not believe is the most important
metric, I say to my friend from North Carolina, who is my
friend and who is very diligent in his efforts. I don't think
time to market is the most important metric. I think safety and
effectiveness is the most important metric, first.
Second, when we talk about FDA days, I'm quite familiar
with that I say again to my friend from North Carolina, who
just had to leave. But why should the clock continue to tick if
FDA asks for additional information from the industry, and they
don't give the information, they drag it out? Why should the
clock continue to run? So again, I understand why we stop the
clock until we get that information in.
Third, on the more money and better job, I think if we look
at the staffing of FDA 20 years ago--well, I'll go before
PDUFA--if you look at the staffing of FDA and the amount and
the number of items that they were involved in approving and
compare to today, when we have MDUFA and PDUFA, and not only
that, we've asked you to do other things, like how about food
safety. We just dumped a lot on you 2 years ago on food safety,
and I can tell you, I want you to do that. I want the FDA to be
more active in inspecting the food that comes from other
countries into this country.
So if you look at all of the things that we've asked FDA to
do in the last 20 years, and the staffing, I think you will see
that if we had kept the staffing at that level, we are
understaffed at FDA right now, quite frankly. We are
understaffed and underfunded.
So again, more money, better job, that's true. You need
more staff to do all the myriad things that we've asked FDA to
do.
Last, I'd just say, as we're reauthorizing this, and the
user fees that came in, which were meant to help FDA do its
job, and it has. I said that in my opening statement. It helped
provide a lot of funding to FDA to help speed up the process to
provide additional personnel. It has done that. I just hope
that there isn't this mistaken idea somewhere out there that
somehow that if you provide the money, you get to buy the
outcome. I don't want the money buying the outcome. I want the
agency to be as independent as possible. I want it to be
scientifically based. I want it to use resources that are also
scientifically independently based.
Balance? Yes, there should be balance in the input that's
coming in. But I don't want anyone to get any mistaken idea
that somehow the money is going to buy the outcome.
With that, I request to keep the record open for 10 days
for Senators to submit statements and questions for the record,
and the hearing will stand adjourned.
Thank you again very much, Commissioner Hamburg.
Commissioner Hamburg. Thank you.

Study of Medical Device Rules Is Attacked Sight Unseen
(By Barry Meier)
Allies of the medical device industry are waging an extraordinary
campaign in Washington to discredit a coming report by one of the
country's pre-eminent scientific groups that examines possible new
regulations on the industry.
The scientific group, the Institute of Medicine, is scheduled to
release a report on Friday that could propose a tougher approval
process for a wide range of devices like hip implants, hospital pumps
and external heart defibrillators. The report, commissioned by the Food
and Drug Administration, comes after several well-publicized recalls in
recent years of devices that have failed in thousands of patients,
causing numerous injuries.
But a business group and others have taken the highly unusual step
of making a pre-emptive strike, arguing that the report is biased. That
attack began even before the study panel finished its review, and has
intensified in recent weeks.
Device producers have also released a series of their own reports
that say more regulation would slow innovation, harm patients and cost
jobs. An official of a group that represents surgeons who implant hips
and other artificial joints has also voiced support for a recent filing
by a pro-business organization that challenged the scientific report's
credibility and argued that the F.D.A. was statutorily required to
ignore it.
Christine Stencel, a spokeswoman for the Institute of Medicine,
which is part of the National Academy of Sciences, said the group was
unaware of a previous instance in which one of its reports, sight
unseen, was the target of a similar effort to invalidate it.
Dr. Sheldon Greenfield of the University of California, Irvine, who
has served on several Institute of Medicine panels, said he was
surprised by the campaign's intensity. ``It is pretty audacious,'' he
said.
The challenge to the panel has been led by Ralph F. Hall, a
professor of law at the University of Minnesota and a device industry
lawyer, who said the criticism was not an attempt tofront-run the
report's conclusions but rather to air legitimate concerns about how
the review had been conducted.
``I could have waited until the report came out,'' Mr. Hall said in
an interview. ``That seems intellectually less than satisfactory with
me.''
Medical experts said the institute's study, regardless of how it
falls, was likely to have a significant impact on patient safety,
device effectiveness and the speed at which new products reached the
market.
With millions of dollars of product sales at stake, the experts
said, it is not surprising that the device industry and others would
want to avert what they see as potentially restrictive new rules.
Still, the lobbying has taken on a tone akin to Washington infighting
over an issue like bank regulation, rather than patient health, they
said.
``We are trying to get to good policies, and the spin game doesn't
help us,'' said Dr. Harlan M. Krumholz, a professor of medicine at Yale
who has served on a different Institute of Medicine panel.
The Institute of Medicine is a widely respected organization that
assembles experts to study a range of health-related issues, often at
the request of government agencies. In 2009, the F.D.A. contracted with
the group to review the adequacy of one of the two regulatory pathways
though which it approves medical devices, a process known as 510K.
Some devices, like implanted heart defibrillators, undergo clinical
trials in patients before they can be sold. But most medical devices,
including implanted hips, go through the 510K route. Under that
pathway, a producer need show only that a new product is
``substantially equivalent'' to one already sold to gain approval.
For example, so-called metal-on-metal artificial hips, which are
currently the subject of scrutiny and lawsuits, appeared to work well
when tested only on mechanical simulators but then failed disastrously
when implanted in patients.
The 12-member review panel assembled by the Institute of Medicine
included physicians, academics and two lawyers who had worked for
device makers on regulatory issues. Another lawyer on the panel, Brian
Wolfman, who once worked for Public Citizen, a consumer advocacy group,
has come under particular attack by business-affiliated groups.
Mr. Wolfman and several other panel members declined to be
interviewed for this article or did not respond to telephone calls or
e-mails.
Last month, the Washington Legal Foundation, a pro-business group,
filed a petition with the F.D.A. arguing that the agency was
statutorily barred from adopting any of the report's recommendations
because of what it claimed was the panel's bias. The legal foundation
argued that the Institute of Medicine had failed to balance the panel
by including officials from industry, the investment community or
patients who had benefited from devices.
``We wanted to let F.D.A. know that there are significant concerns
with the composition of the committee,'' said Richard A. Samp, a lawyer
for the legal foundation.
Mr. Samp said his organization took action after the issue was
brought to its attention by a lawyer who works at a firm that
represents device makers. Shortly after filing its petition, the legal
foundation was contacted by an official of the American Academy of
Orthopaedic Surgeons, which represents doctors who perform joint
replacements, who congratulated it for ``taking the bull by the
horns,'' Mr. Samp said.
A spokeswoman for the doctors' group confirmed that one of its
officials had called Mr. Samp, adding that it was concerned that the
Institute of Medicine panel did not include a practicing surgeon.
William Skane, a spokesman for the National Academy of Sciences,
said the group worked hard to balance its committees and barred people
from serving on a panel if they had a financial conflict of interest or
a clear bias on an issue.
Dr. William Maisel, the chief scientist of the F.D.A. division that
oversees medical devices, said the agency was satisfied with the
panel's makeup.
``I think it would be difficult to find a more reputable scientific
organization than the Institute of Medicine,'' Dr. Maisel said. He
added that the F.D.A. was not bound to accept the report's
recommendations.
Over the last year, the panel charged with reviewing device
approvals has also held hearings to gather feedback and data from all
interested parties, including device producers and investors.
Earlier this year, Mr. Hall, the lawyer and Minnesota professor,
wrote an article with a colleague, arguing that the Institute of
Medicine, in selecting its panel, had violated a little-known rule, the
Federal Advisory Committee Act, which requires balance on such
committees.
In the interview, Mr. Hall acknowledged that he had worked either
directly or in the same law firm with the two lawyers on the panel who
had advised device makers on F.D.A matters.
At a Congressional hearing this month, the editors of two medical
journals--The Journal of the American Medical Association, The New
England Journal of Medicine and the Archives of Internal Medicine--
questioned the value of two industry-backed studies that claimed that
new regulations would create hardships for patients and producers,
describing them as methodologically flawed.

In recent years, FDA has taken measures that have resulted in an
increased number of foreign inspections, a more sophisticated approach
to identifying facilities for inspection, and a more streamlined
approach to conducting inspections. For example, we have implemented
collaborative efforts with our foreign counterparts, and we have issued
a new compliance program within the Compliance Program Guidance Manual
(CPGM) for pre-approval inspections that strengthens the criteria for
determining when a pre-approval inspection is necessary. We also have
established a cadre of dedicated foreign investigators, managed from
headquarters with employees located in FDA districts whose work is
dedicated to conducting foreign inspection assignments. It is important
to note, however, that inspections are necessary but not sufficient to
ensure quality.
In large part as a result of these initiatives, FDA has increased
the frequency of its foreign Current Good Manufacturing Practice (CGMP)
surveillance inspections from 347 in Fiscal Year 2007 to 443 in fiscal
year 2010 and the Agency is better positioned to conduct enforcement
followup after the issuance of a Warning Letter (WL). The number of WLs
issued to foreign facilities also has increased significantly. For
example, in calendar year 2008 the Agency issued four WLs to foreign
facilities (two to sites in China and two to sites in India), and in
2010, the Agency issued 19 WLs to foreign facilities, also including
sites in China and India.
gao recommendation
FDA should ``[c]onduct timely inspections of foreign establishments
that have received warning letters to determine continued compliance.''
\2\
---------------------------------------------------------------------------
\2\ Ibid. page 43.
---------------------------------------------------------------------------
During 2010, FDA issued 19 WLs to foreign establishments. Of the 19
establishments that received WLs during 2010, six have been re-
inspected. Of the 13 foreign firms to which the Agency issued WLs in
2009, the Agency has already re-inspected 11. The remaining firms are
either implementing corrective action plans or will be re-inspected in
the near future. Once re-inspected, FDA will determine if they are in
compliance with GMPs and evaluate whether or not they can be removed
from import alert status.
gao recommendation
FDA should ``enforce the requirements that establishments
manufacturing drugs for the U.S. market update their registration
annually.'' \3\
---------------------------------------------------------------------------
\3\ Ibid. page 43.
---------------------------------------------------------------------------
agency response
Under the Federal Food, Drug, and Cosmetic Act (FD&C Act or the
Act) most foreign drug establishments shipping drugs to the United
States must register with FDA electronically. Registration is completed
through FDA's electronic drug registration and listing system (eDRLS)
and must be resubmitted on or before December 31 of each calendar year.
The implementation of eDRLS helps FDA to identify foreign
establishments that have not satisfied their statutory registration
obligations and helps the Agency to assemble more reliable information
about drug establishments.
Revising FDA's statutory provisions to modernize drug registration
and listing may improve the timeliness, completeness, and accuracy of
FDA's current database, making sure that FDA has accurate and up-to-
date information about foreign and domestic parties involved in medical
product manufacture.
gao recommendation
FDA should ``[e]stablish mechanisms for verifying information
provided by the establishment at the time of registration.'' \4\
---------------------------------------------------------------------------
\4\ Ibid. page 43.
---------------------------------------------------------------------------
agency response
FDA recently hired a contractor to verify registrations of foreign
fines. A total of 373 site visits were conducted over a 3-year period.
Of the 373 visits, 142 sites were drug firms. Two-hundred and thirty
sites were food firms, and one site was a medical device firm. The
contract ended in August 2011 and FDA is also continuing to explore
additional avenues for verifying the registration information submitted
by foreign facilities.
FDA, working with Dun and Bradstreet (D&B), has established a pilot
project to verify foreign establishments in the drug GMP inventory for
whom FDA's records are incomplete or dated. The U.S. Customs and Border
Protection identified for the pilot nearly 160 establishments who have
shipped drugs to the United States from these countries in recent
years. D&B employees located in India and China are using phone calls,
email, site visits or a combination of these methods to engage to
attempt to acquire complete and accurate registration information.
About two-thirds of the verifications are complete.
FDA is also working towards use of a unique facility identifier,
such as the D&B DUNS number, which would allow the Agency to verify the
accuracy of registration information using robust, established
databases. Section 510(e) of the FD&C Act states that the Secretary may
assign a registration number to any establishment registered in
accordance with section 510. However, FDA does not currently have
explicit statutory authority to require the submission of a unique
identifier, such as a DUNS number, as a condition of drug establishment
registration and drug import. Current FDA guidance states that DUNS
numbers serve as the registration numbers for drug establishments in
the electronic system, and thus recommends, but does not require, that
industry provide DUNS numbers during the registration and listing
process.
gao recommendation
FDA should ``[e]nsure that information on the classification of
inspections with serious deficiencies is accurate in all FDA
databases.'' \5\
---------------------------------------------------------------------------
\5\ Ibid, page 43.
---------------------------------------------------------------------------
agency response
In 2008, GAO identified discrepancies between the Office of
Regulatory Affairs' (ORA's) Field Accomplishments and Compliance
Tracking System (FACTS) database and the Center for Drug Evaluation and
Research's (CDER's) Office of Compliance Foreign Inspection Tracking
System (OCFITS) database, with regard to the types of action indicated
in following a foreign inspection. Since GAO's report, FDA has
identified the cause of these discrepancies and has implemented
measures to prevent them in the future.
CDER's Office of Compliance has now replaced OCFITS with a new
information management system referred to as Compliance Management
Services. The new system links directly to FACTS for some critical
information and the information about sites and inspection events is
more accurate than the earlier system, OCFITS.
gao recommendation
FDA should [c]onduct more inspections to ensure that foreign
establishments manufacturing drugs currently marketed in the United
States are inspected at a frequency comparable to domestic
establishments with similar characteristics.'' \6\
---------------------------------------------------------------------------
\6\ Ibid, page 43.
---------------------------------------------------------------------------
agency response
FDA has committed to conducting more foreign inspections to achieve
the Agency's goal of addressing the risks posed by the global supply
chain. The Agency increased foreign inspections by 27 percent from 2007
to 2010 as stated above and it continues to identify opportunities for
increasing our surveillance and knowledge about foreign drug
manufacturers whose drugs are consumed in the United States.
The statute directs FDA to inspect domestic manufacturers every 2
years. However, an overall risk-based approach to foreign and domestic
inspections would be a far better approach than a mandatory inspection
frequency. There are a number of obstacles that make conducting foreign
inspections challenging, including:
Cost of conducting foreign inspections--it is
exponentially more expensive to conduct a foreign inspection than a
domestic inspection.
Sovereignty issues--FDA must obtain a visa to enter a
foreign country in order to conduct an inspection, and a firm does not
have to let FDA in, although the product would not be approved if a
pre-approval inspection is necessary.
Cooperation with the foreign firm--FDA must notify foreign
firms of the Agency's intent to conduct an inspection and rely upon
foreign firms to facilitate the inspection. While foreign firms that
refuse to permit FDA inspection present a challenge to achieving a 2-
year inspection frequency, it does not impede FDA's ability to protect
the safety of the drug supply. FDA may refuse entry of goods from
foreign firms that refuse to permit FDA inspection and may withhold
approval of pending new drug applications submitted by firms that
refuse to permit an FDA inspection.
Given the challenges in achieving a 2-year inspection frequency
abroad, FDA has supplemented its use of foreign inspections with other
reliable sources of compliance information and has instituted risk
analytics to make best use of this information, including:
Using the PREDICT import information technology system to
target the highest-risk entries for further scrutiny, field
examinations, and/or sample collection analyses.
Establishing dedicated foreign cadres: FDA has established
dedicated cadres of foreign investigators for pharmaceutical, device,
and foreign food inspections.
Increasing leveraging: FDA continues to increase its
collaborative efforts with foreign counterparts.
gao recommendation
FDA should ``take steps to enhance strategic planning to ensure
coordination between overseas and domestic activities and develop a
workforce plan to help recruit and retain overseas staff.'' \7\
---------------------------------------------------------------------------
\7\ GAO, Overseas Offices Have Taken Steps to Help Ensure Import
Safety, but More Long-term Planning is Needed, GAO-10-960, Highlights.
---------------------------------------------------------------------------
agency response
We now have permanent FDA overseas posts in Beijing, Shanghai. and
Guangzhou, China; New Delhi and Mumbai, India; San Jose, Costa Rica;
Mexico City, Mexico; Santiago, Chile; Brussels, Belgium; London,
England; and Parma, Italy. This year, we have opened posts in Amman,
Jordan and Pretoria, South Africa. These offices enable us to have a
regional presence around the world and serve as important hubs for
improved coordination with regulatory authorities and industry in other
nations. FDA personnel assigned to these posts can also conduct and
facilitate inspections.
The Agency is doing strategic and operational planning for its
foreign offices and has initiated a workforce planning process. As
noted in the GAO report, FDA recognizes that this process will be
ongoing and informed by the experience of several cycles of overseas
staff appointments (deployment and return), and that the Agency will
benefit from the process.
We are also supporting our strategic planning efforts by employing
the FDA-TRACK performance management initiative to identify and track
performance indicators and milestones for key program activities. The
transparency of this management process contributes to the coordination
of our overseas and domestic activities. For more information, please
visit: http//www.fda.gov/AboutFDA/Transparency/track/default.htm.
agency reorganization
You also asked how our recent reorganization will help us make
additional progress. On July 13, 2011, we announced that the Office of
the Commissioner (OC) would be restructured to more accurately reflect
the Agency's responsibilities, subject matter expertise, and mandates
in an ever-increasing complex world, where products and services do not
fit into a single category. OC has been divided into ``directorates''
that reflect the core functions and responsibilities of the Agency.
This new management structure will enable OC to better support the
Agency's core scientific and regulatory functions, and help tie
together programs that share regulatory and scientific foundations.
As part of this reorganization, the Agency created a new position,
Deputy Commissioner for Global Regulatory Operations and Policy, to
provide broad direction and support to ORA and to the Office of
International Programs. The Deputy Commissioner is charged with
ensuring that FDA responds to the challenges of globalization and
import safety and ensures that globalization issues are a top priority
for the Agency in the years to come.
Question 2. FDA has committed to provide a guidance on the
artificial pancreas by December of this year. Publication of a draft
guidance is a very important first step, but it is just that, a first
step. Can you assure me that the final guidance will reflect the input
of clinical experts and that FDA will finalize it in a timely way so
products can be timely tested and moved to market?
FDA is committed to facilitating and expediting development of the
artificial pancreas and continues to work diligently with stakeholders.
The low-glucose suspend system draft guidance, issued on June 22, 2011,
was developed with considerable input from industry, researchers, and
the clinical community. The Agency requested additional feedback
through a 90-day public comment period. FDA is now reviewing and
addressing the comments received and will finalize that guidance
document as expeditiously as possible.
As part of the outreach for the low-glucose suspend draft guidance.
FDA specifically targeted health care professionals, alerting them to
the availability of the draft guidance and asking for their comment.
Provider groups targeted include the Diabetes Technology Society, the
American Association of Clinical Endocrinologists, the American
Diabetes Association, the Endocrine Society, the Juvenile Diabetes
Research Foundation, the National Institutes of Health, the Endocrine
Nurses Society, and the American Association of Diabetes Educators.
FDA will continue to collaborate with the medical community and
other stakeholders and will continue our efforts to prioritize and
expedite clinical research in this area.
A critical aspect of a second draft guidance, which is currently
under development, for the more sophisticated treat-to-target or treat-
to-range systems \8\ is addressing their safety in real-world
scenarios, i.e., outside of the protection of the clinical or hospital
setting. That guidance is projected for publication in December 2011.
---------------------------------------------------------------------------
\8\ A treat-to-range system reduces the likelihood of a
hypoglycemic event or a hyperglycemic event (when blood glucose is
dangerously high) by adjusting insulin dosing only if a person's
glucose level approaches the low or high glucose thresholds. Patients
using this system will still need to check blood glucose levels with a
glucose meter and give themselves insulin to maintain control of
glucose levels. A treat-to-target system sets target glucose levels and
tries to achieve these levels at all times. It would be fully automated
and require no interaction from the user, except for calibration of the
continuous glucose monitoring system.

senator alexander
Question 1. I have heard from a start-up device company in my home
State of Tennessee that, ``Whenever people call us looking for
employment we tell them we can't hire them, because the Federal
Government won't let us.'' They went on to cite some of the several
studies published in recent months that make comparisons between the EU
and U.S. systems of medical device regulation, which they feel indicate
that the FDA is over-regulating the U.S. medical device industry, which
has a negative effect on the industry's ability to raise capital and
create jobs and doesn't make medical devices safer in the United States
than they are in Europe.
My question is, why if a product is available in Europe would that
product need to go through more pre-clinical testing before beginning a
U.S. clinical trial? Why isn't an EU CE Mark approval (``European
Conformity'' meaning it conforms to all required safety and health
standards) to use in humans enough to allow access for Americans via a
clinical trial?
Answer 1. The FD&C Act requires that a Class III medical device
(i.e., those with the highest risk) be approved on the basis of
clinical data demonstrating reasonable safety and effectiveness for its
intended uses. The fact that a device has received the European Union
(EU) CE mark of approval tells us nothing about the clinical data
underlying that decision. However, FDA does not require studies to
support device approvals to be conducted in the United States. We
accept trials or data from outside the United States as long as the
studies meet regulatory standards and are applicable to U.S.
populations.
Data collected from other countries can be used to support a
product's safety and effectiveness. Foreign studies performed under an
Investigational New Drug (IND) application or Investigational Device
Exemption (IDE) must meet the same requirements of 21 CFR part 312 or
21 CFR part 812, respectively, that apply to U.S. studies conducted
under an IND or IDE. The acceptance of foreign clinical studies not
conducted under an IND or IDE, as support for a marketing application,
is generally governed by 21 CFR 312.120 and 21 CFR 814.15.
A marketing application that is based solely on foreign clinical
data meeting U.S. criteria for marketing approval may be approved if:
the foreign data are applicable to the U.S. population and
medical practice;
the studies have been performed by clinical investigators
of recognized competence; and
the data may be considered valid without the need for an
on-site inspection by FDA or if FDA considers such an inspection to be
necessary, FDA can validate the data through an on-site inspection or
other appropriate means.
Question 2. Is there something about the U.S. device review system
that is inherently slower than that of the EU? Yes there are different
standards, but is there something unique about our system that leads to
delays in patient access?
Answer 2. A recent industry-sponsored study \9\ compared time to
market between the United States and the EU. Although the study is
flawed in some regards, it does show that devices subject to a 510(k)
without clinical data tend to come on the market first, as often or
more often in the United States as in the EU. That's approximately 90
percent of devices marketed in the United States. Higher risk medical
devices are typically approved faster in the EU than in the United
States because, unlike the United States, the EU does not require the
manufacturer to demonstrate that the device actually benefits patients.

Group. ``Competitiveness and Regulation: The FDA and the Future of
America's Biomedical Industry'' (Feb. 2011), available at http://
www.bdg.com/documents/file72060.pdf.
Question 3. Could you please define ``reasonable assurance? '' Does
this term also include some risk?
Answer 3. Although a manufacturer may submit any form of evidence
to FDA in an attempt to substantiate the safety and effectiveness of a
device, by statute the Agency must rely upon valid scientific evidence
to determine whether there is ``reasonable assurance'' that the device
is safe and effective. After considering the nature of the device and
the rules in 21 CFR 860.7, FDA determines whether the evidence
submitted or otherwise available to FDA is valid scientific evidence
for the purpose of determining the safety or effectiveness of a
particular device, and whether the available evidence, when taken as a
whole, is adequate to support a determination that there is reasonable
assurance that the device is safe and effective for its conditions of
use.
There is reasonable assurance that a device is safe when it can be
determined, based upon valid scientific evidence, that the probable
benefits to health from use of the device for its intended uses and
conditions of use, when accompanied by adequate directions and warnings
against unsafe use, outweigh any probable risks.
In order for industry and others to better understand how FDA makes
these decisions, we recently published for public comment a ``Draft
Guidance for Industry and Food and Drug Administration Staff--Factors
to Consider when Making Benefit-Risk Determinations in Medical Device
Premarket Review,'' which may be viewed at http://www.fda.gov/
MedicalDevices/DeviceRegulationandGuidance/Guidance
Documents/ucm267829.htm.
Question 4a. I hear from device manufacturers that they are looking
for more consistency and predictability, which you state in your
testimony that you have heard for yourself, and the standard in the
United States is safety and effective while in the EU the standard is
safety and performance. Is there something about the U.S. standard that
prevents FDA from providing consistency and predictability in the
review process? (YES OR NO)
Answer 4a. No. There is nothing inherent in the U.S. standard that
prevents consistency and predictability in the review process. However,
safety and effectiveness is a higher standard than safety and
performance. For example, in the EU, to clear a laser to cut heart
tissue to treat heart arrhythmia, it must only be demonstrated that the
device cuts tissue. In the United States, it must be demonstrated that
the patient actually benefits from the cutting of the tissue, i.e.,
that the laser treats the arrhythmia.
Comparisons between the United States and EU systems are not easy
to make, as the European device review process is less transparent than
FDA's. There are significant differences between the EU and U.S. device
review systems. In the EU:
Manufacturers do not have to demonstrate that their
products are effective at treating the disease or condition for which
they are approved;
Private entities chosen and paid by manufacturers review
and approve medical devices by giving them a CE mark; these decisions
are kept confidential and not released to the public or to EU
regulatory bodies;
There is not one, centralized regulatory body for review
of medical devices: instead, each member State has its own system for
determining reimbursement of medical devices and it is impossible to
track approvals, adverse events, or recalls; and
There is little to no publicly accessible, centralized
system for collecting and monitoring information about device approvals
or safety problems.
These differences have recently been highlighted by several
prestigious European medical journals. Both the British Medical Journal
\10\ and the European Society of Cardiology \11\ have published reports
noting that the lack of transparency and clinical data requirements in
the EU system have led to patient harm.

For more information about steps FDA is taking to improve
consistency and predictability in its review processes, see the answer
to the following question.
Question 4b. Why are we seeing this lag? Is it because your
reviewers are not properly trained? Is it because you are not using
resources at your disposal such as interactive review? Is it because
FDA guidance is lacking?
Answer 4b. As noted in answer to question #2, a recent industry-
sponsored study \12\ compared time to market between the United States
and the EU. Although the study is flawed in some regards, it does show
that devices subject to a 510(k) without clinical data tend to come on
the market first, as often or more often in the United States as in the
EU. That's approximately 90 percent of devices marketed in the United
States. Higher-risk medical devices are typically approved faster in
the EU than in the United States because, unlike the United States, the
EU does not require the manufacturer to demonstrate that the device
actually benefits patients.

---------------------------------------------------------------------------
Although FDA is meeting its 510(k) performance goals under MDUFA,
overall time to decision (i.e., FDA review time plus industry response
time) for 510(k) submissions has increased over the past 10 years, due
primarily to an increase in the number of review cycles and in the
amount of time companies take to respond to requests for additional
information.
We recognize our role in this and are taking steps to address it.
The two reports we released publicly in August 2010, with our analyses
and recommendations, showed that we have not done as good a job
managing our premarket review programs as we should and that we need to
take several critical actions to improve the predictability,
consistency, and transparency of these programs.
For example, we have new reviewers who need better training. We
need to improve management oversight and standard operating procedures.
We need to provide greater clarity for our staff and for industry
through guidance about key parts of our premarket review and clinical
trial programs and how we make benefit-risk determinations. We need to
provide greater clarity for industry through guidance and greater
interactions about what we need from them to facilitate more efficient,
predictable reviews. We need to make greater use of outside experts who
understand cutting-edge technologies. And we need to find the means to
handle the ever-increasing workload and reduce staff and manager
turnover, which is almost double that of FDA's drugs and biologics
centers.
In January 2011, FDA announced a Plan of Action that included 25
specific actions that we would take this year to improve the
predictability, consistency, and transparency of our premarket
programs. The following month, we announced our Innovation Initiative,
which included several proposals to help maintain the position of the
United States as the world's leader in medical device innovation,
including the creation of a new approach for important, new
technologies called the Innovation Pathway.
Since then, we have announced additional efforts to improve our
premarket programs, including actions to improve our program for
clinical trials and the Investigational Device Exemption (IDE) program.
The actions we are taking can be grouped into three main areas of
emphasis:
Create a culture change toward greater transparency,
interaction, collaboration, and the appropriate balancing of benefits
and risks;
Ensure predictable and consistent recommendations,
decisionmaking, and application of the least-burdensome principle; and
Implement efficient processes and use of resources.
Specific steps that we are taking, many of which are supported by
industry, include:
Issuing guidance clarifying the criteria used to make
benefit-risk determinations a part of device premarket decisions to
provide greater predictability and consistency and apply a more
patient-centric approach by considering patients' tolerance for risk in
appropriate cases (draft guidance issued August 15, 2011);
Creating standard operating procedures for when a reviewer
can request additional information regarding a premarket submission and
at what management level the decision must be made to provide greater
predictability, consistency, and the appropriate application of the
least-burdensome principle by reducing the number of inappropriate
information requests (Standard Operating Procedures issued November
2011);
Developing a range of updated and new guidances to clarify
CDRH requirements for predictable, timely, and consistent product
review, including device-specific guidance in several areas such as
mobile applications (draft guidance released July 19, 2011) and
artificial pancreas systems (to be completed by the end of 2011);
Revamping the guidance development process through a new
tracking system and, to the extent resources permit, core staff to
oversee the timely drafting and clearance of documents (to be completed
by the end of 2011);
Improving communication between FDA and industry through
enhancements to interactive review (some of these enhancements will be
in place by the end of 2011);
Streamlining the clinical trial and IDE processes by
providing industry with guidance to clarify the criteria for approving
clinical trials, and criteria for when a first-in-human study can be
conducted earlier during device development to create incentives to
bring new technologies to the United States first (guidance to be
issued November 2011) (IDEs are required before device testing in
humans that involve significant risks may begin, and they ensure that
the rights of human subjects are protected while gathering data on the
safety and efficacy of medical devices);
Implementing internal business process improvements to
ensure that decisions are made by the appropriate level of management,
that decisions are made consistently and efficiently, and that we
appropriately apply the least-burdensome principle. For example, CDRH
created the internal Center Science Council (Council) to actively
monitor the quality and performance of the Center's scientific programs
and ensure consistency and predictability in CDRH scientific
decisionmaking (Council established March 31, 2011);
Creating a network of experts to help CDRH resolve complex
scientific issues, which will ultimately result in more timely reviews.
This network will be especially helpful as FDA confronts new
technologies (Standard Operating Procedures issued September 30, 2011);
Instituting a mandatory Reviewer Certification Program for
new reviewers (program launched September 2011);
Instituting a pilot Experiential Learning Program to
provide review staff with real-world training experiences as they
participate in visits to manufacturers, research, and health care
facilities, and academia (to begin in early 2012);
Providing industry with specific guidance on how to ensure
the quality and performance of clinical trials while applying the
least-burdensome principle, and thereby conduct studies that are more
likely to support the approval of their products (guidance released
August 15, 2011); and
Streamlining the de novo review process, the pathway by
which novel, lower-risk devices without a predicate can come to market
(draft guidance released September 30, 2011).
A recent FDA analysis \13\ shows that poor submission quality is a
major contributor to the increase in total review times. The most
common deficiencies included:
---------------------------------------------------------------------------
\13\ CDRH, ``Analysis of Premarket Review Times Under the 510(k)
Program'' (July 2011), available at http://www.fda.gov/AboutFDA/
CentersOffices/CDRH/CDRHReports/ucm263385.htm
#5.
Inadequate device descriptions;
Discrepancies throughout the submission;
Failure to address necessary information as outlined in
guidance documents;
Problems with the proposed indications for use;
Completely missing performance testing; and
Completely missing clinical data.
In addition, sponsors' failure to address deficiencies identified
in first-round Additional Information (AI) Letters is a major
contributor to the increase in total review times. For example, 65
percent of the time, FDA sent a second-round AI Letter because the
sponsor failed to submit information requested in the first AI Letter.
FDA has already taken steps to address some of the issues
identified in this analysis. We are working to provide greater
predictability for industry by communicating justified changes in data
requirements more quickly and transparently. We recently issued draft
Standard Operating Procedures for Notice to Industry Letters,\14\ which
provides a format for communicating changes more quickly within the
existing Good Guidance Practices framework. FDA is also enhancing
training for staff and industry, which is aimed at reducing
inappropriate requests for additional information and helping sponsors
understand when they are required to submit data. We will continue to
work with industry to identify additional actions to reduce the average
number of review cycles and the percent of 510(k) submissions for which
an AI Letter is sent.
---------------------------------------------------------------------------
\14\ CDRH, ``Standard Operating Procedure for `Notice to Industry'
Letters'' (August 2011), available at http://www.fda.gov/downloads/
MedicalDevices/DeviceRegulationand Guidance/GuidanceDocuments/
UCM259172.pdf.
---------------------------------------------------------------------------
Through these and other steps we are taking to address weaknesses
in the 510(k) program, FDA aims to reduce the total time to clearance
for 510(k) devices, while assuring that we maintain the same levels of
safety and effectiveness. It is our hope that taking actions to
increase submission quality and avoid inappropriate requests for
additional information will prevent avoidable delays and reduce total
time to decision, which will, in turn, get safe and effective devices
to market faster.
With regard to PMA applications, FDA's internal analysis found
that, for those PMAs that were not reviewed within the performance
goals, the main reasons for the longer review times were:
Poor quality clinical studies, such as clinical trial
execution issues and problematic data analyses;
Reviewer turnover, especially changing medical officers
and branch chiefs; and
Taking a PMA to an FDA advisory committee. (In general,
all PMAs for the first-of-a-kind device are taken before the
appropriate advisory panel for review and recommendations. The
preparation for an FDA advisory committee involves significant calendar
time and review team resources.)
Question 4c. While I appreciate that you have taken steps to
address some of these issues, what else are you doing right now in the
short term to manage and increase consistency and predictability in the
review process?
Answer 4c. Our most recent activities aimed at increasing
consistency and predictability in the medical device review process
include the following:
On September 6, 2011, CDRH announced that our new Reviewer
Certification Program, which began as a pilot in April 2010 with
participants from CDRH's Division of Anesthesia, General Hospital, and
Infection Control and Dental Devices, would launch that month and is
intended to include all new device reviewers. The program includes up
to 18 months of training, aimed at complementing the skills and
knowledge that new reviewers bring to CDRH from fields such as
biomedical engineering and health care. Reviewers in the program will
complete online training modules and instructor-led courses, and obtain
practical experience in the medical device review process.\15\
---------------------------------------------------------------------------
\15\ CDRH also announced that it is developing a pilot Experiential
Learning Program for premarket reviewers. which will include visits to
academic institutions, manufacturers, research organizations, and
health care facilities and is intended to give reviewers a better
understanding of how medical devices are designed, manufactured and
used. The Experiential Learning Program is in the design stage and
scheduled to begin as a pilot program in 2012.
---------------------------------------------------------------------------
On August 15, CDRH issued draft guidance (with a request
for public comment) to help researchers and manufacturers design better
quality clinical studies in support of PMA applications for medical
devices. Manufacturers submit PMA applications for high-risk (Class
III) medical devices. These applications undergo the most stringent
type of FDA device review. PMA submissions include data from pivotal
clinical studies, which FDA uses, along with other information, in
determining approval.
Also on August 15, CDRH published draft guidance (with a
request for public comment) clarifying how benefit-risk determinations
are made during premarket review of certain medical devices. The
guidance focuses on PMAs--the regulatory pathway for high-risk medical
devices. The recommendations made in the guidance are intended to
improve the predictability, consistency and transparency of the
premarket review process for applicable devices, and should help
manufacturers navigate the approval process more easily.
Question 5. I have another question relating to the consistent
application of regulatory standards and maintaining a level playing
field for all manufacturers. Again, I have heard from manufacturers in
Tennessee who feel that the current criteria demanded by CDRH to
evaluate new medical devices in a specific product class can seem
arbitrary. They feel the criteria often are inconsistent with FDA
precedent for similar devices, and changes in the criteria are not
scientifically justified by CDRH. They say it has become a noticeable
trend during the last 2 years, and is exacerbated by staffing changes
at the agency and lack of reviewer training. More specifically, CDRH
appears to be applying clinical trial success requirements that are
significantly different with respect to primary and secondary endpoints
from those that have been used to evaluate and approve other products,
even those approved within the past 18 months. The application of new
standards for approvability of similar products that exceed the
standards applied to contemporary approvals negatively impact both
patients and jobs while also increasing healthcare costs by limiting
competition. Please comment on the regulatory process and statutory
standards at CDRH that allow review teams to arbitrarily (no scientific
or regulatory standard basis) apply different criteria to the new
products of a given class that are far above those criteria used to
approve similar device types that have been recently (within the past
18 months) reviewed by an FDA Advisory Panel and approved by the FDA.
Answer 5. Consistent with the requirements for 510(k) submissions,
FDA may require clinical data when a firm seeks a new indication for
use or where there are differences in the technological characteristics
between the firm's device and its predicate that could affect safety or
effectiveness. FDA asks for clinical studies in only 8 to 10 percent of
510(k) submissions, and often the requested studies are simple and
small. For example, FDA recommends that for pulse oximeters--medical
devices that indirectly monitor the oxygen saturation of a patient's
blood--clinical data be collected from as few as 10 patients. In
addition, for establishing clinical data in support of a 510(k)
application, the Agency recognizes a standard set by the Association
for the Advancement of Medical Instrumentation, which requires a
validation study consisting of as few as 35 subjects for which clinical
data are required. Consistent with statutory requirements, all PMAs
contain clinical data.
The Agency has no data to suggest that, as a general matter, FDA
has demanded larger, more extensive clinical trials in the past 5 years
for 510(k)s or PMAs. Clinical studies are tailored to the type of
device and the specific questions that need to be addressed. That is
not to say that FDA demands full knowledge and understanding of long-
term risks and performance before it will approve a device for
marketing. For PMA devices, the Agency increasingly uses its authority
to require post-approval studies to answer important, specific
questions regarding device performance after the device has been
approved for marketing. For example, if there are questions about long-
term durability of an implanted device, the Agency may allow the device
to be marketed while further data collection continues to address that
issue.
Whenever possible, FDA seeks to minimize clinical trial or
preclinical requirements when scientific knowledge suggests that this
is appropriate. For example, establishing the safety and effectiveness
of a first-generation drug eluting stent (DES) required extensive
preclinical testing programs and clinical studies. However, the
fundamental work performed to gain initial approval of first-generation
DES devices has been successfully leveraged by several DES
manufacturers to decrease clinical trial requirements for next-
generation stents, which typically incorporate modest changes to the
first-generation design.
More specifically, FDA reviewers concluded that a single-arm
clinical trial (rather than a randomized controlled study) would be an
acceptable design for the pivotal IDE trials of the Boston Scientific
TAXUS LiberteTM, Abbott XIENCE PrimeTM, and
Medtronic Resolute next-generation DES. The reason CDRH permitted this
approach is that these devices represent iterations of prior DES, in
which a component of the combination product has been modified (e.g., a
polymer coating or stent platform). This was acceptable based on our
analysis of the comprehensive preclinical and clinical data generated
from the prior generation DES, and demonstrates the Agency's
flexibility and willingness to tailor data requirements when
appropriate.
Another example is the total artificial hip. CeramTec purchased the
rights to the Wright Medical TRANSCEND ceramic-on-ceramic total
artificial hip clinical data set and approved PMA. Because the
articulating surfaces of the components are all manufactured by
CeramTec, FDA allowed manufacturers to use preclinical testing to
leverage the Wright Medical TRANSCEND data set. Five manufacturers had
their PMAs approved referencing the TRANSCEND clinical data set with a
condition of approval to conduct a post-approval study in a new cohort
of patients.
This sometimes works in the other direction, too, in that
information gleaned from competitor application reviews and post-market
studies may bring to light information that changes the risk-benefit
analysis and causes the Agency to look more critically at the next
submission in a product category. This is appropriate. The reasons for
it cannot always be shared with applicants due to statutory
confidentiality requirements, possibly causing the Agency to appear
arbitrary.
Under the 510(k) Action Plan, we have established an internal
Center Science Council (Council) to actively monitor the quality and
performance of the Center's scientific programs and ensure consistency
and predictability in CDRH scientific decisionmaking. The Council,
which is comprised of experienced managers and employees, operates
under the direction of the Deputy Center Director for Science and is
responsible for overseeing science-based decisionmaking across CDRH,
including premarket review; periodically auditing decisions and
assessing program performance; and acting as a resource for staff on
scientific questions, to support greater consistency in decisionmaking
and the treatment of cross-cutting issues. We are also creating a
network of experts to help CDRH resolve complex scientific issues. This
network will be especially helpful as FDA confronts new technologies.
And we are instituting a mandatory Reviewer Certification Program for
new reviewers, as detailed in our answer to question #4.
Question 6. Last week, the FDA released a report called the
``Analysis of Premarket Review Times under the 510(k) Program.'' In
reviewing this report, I am curious about the FDA's conclusion that in
the Premarket Review Time analysis that poor quality submissions are
the major cause of the increased review times for 510(k) submissions.
Is the FDA implying that the medical device industry has universally
forgotten how to submit a good, quality application? Could another
explanation be that application process has become less predictable,
more risk averse, and therefore, is requiring more data and information
in 510(k) submissions than it has in the past?
Answer 6. FDA's standards for the review of medical devices are
specified in statute and our application of those standards has not
changed.
Application quality has always varied and the Agency has
consistently strived to help device manufacturers, many of which are
small companies, through a sometimes unfamiliar process, rather than
refuse deficient applications. Since the advent of MDUFA, the time cost
associated with that extra assistance has taken on added significance.
The study cited in your question--which is available on FDA's Web
site at: http:// www.fda.gov/AboutFDA/CentersOffices/CDRH/CDRHReports/
ucm263385
.htm--showed that poor submission quality and sponsors' failure to
address deficiencies identified in first-round AI Letters are major
contributors to the increase in total review times. We are pleased
that, in response to FDA calls for improving the quality of premarket
submissions, the medical device trade association, AdvaMed, has
improved and made available more training courses for its companies to
help them develop 510(k) and PMA submissions that meet FDA standards.
We also recognize our role in this and are taking steps to address
it. The two reports we released publicly in August 2010, with our
analyses and recommendations, showed that we had not done as good a job
managing our premarket review programs as we should and that we need to
take several critical actions to improve the predictability,
consistency, and transparency of these programs.
In January 2011, FDA announced a Plan of Action that included 25
specific actions that we would take this year to improve the
predictability, consistency, and transparency of our premarket
programs. The following month, we announced our Innovation Initiative,
which included several proposals to help maintain the position of the
United States as the world's leader in medical device innovation,
including the creation of a new approach for important, new
technologies called the Innovation Pathway. For details on specific
activities, please see our response to question #4.
Question 7. The Analysis of Premarket Review Times under the 510(k)
Program, released last week, states that,
``FDA develops guidance documents and recognizes standards
established by national and international standards development
organizations to provide greater predictability, consistency
and transparency in our premarket review programs.''
Yet, I along with my colleagues keep hearing from companies in our
States that just the opposite is occurring specifically, we hear that
the goal posts keep being moved. Additional Information (AI) letters
are issued requiring submitters to provide data that are above and
beyond what is stated in the guidance documents, as well as other
deviations from published guidance and standards. What is FDA doing to
ensure that all guidance available to the public is up-to-date, and if
not, that all data requirements not addressed in, or changed from,
current guidance are consistently conveyed to industry prior to
submission of a 510(k)?
Answer 7. Developing and updating guidance documents is a resource-
intensive task, currently performed by the same professionals who
review device applications. Additional resources devoted to guidance
development are necessary to optimize this function. Nevertheless, we
are taking steps to improve the guidance development process through
the 510(k) Action Plan \16\ and have stepped up development of specific
guidance documents that will make the review process more predictable,
consistent, and transparent. Examples include streamlining de novo
classification, clarifying when changes to a device require a
510(k),\17\ and improving the quality of clinical trials.\18\

---------------------------------------------------------------------------
The study that you reference \19\ showed that reviewers do not
often ask for data inappropriately. Results of first round AI Letters
in Cohort 1 showed that reviewers asked for data that had not
previously been requested for particular device types only 12 percent
of the time. Of those requests, 8 percent were inappropriate. Results
of second round AI Letters in Cohort 2 showed that reviewers asked for
data that had not been previously requested 4 percent of the time. Of
those requests, 2 percent were inappropriate.

Program'' (July 2011), available at http://www.fda.gov/AboutFDA/

---------------------------------------------------------------------------
This analysis shows that poor submission quality and sponsors'
failure to address deficiencies identified in first-round AI Letters
are major contributors to the increase in total review times. For
example, 65 percent of the time FDA sent a second-round Al Letter
because the sponsor failed to submit information requested in the first
Al Letter. However, FDA has also contributed to the increase by making
inappropriate requests for additional information in limited instances.
FDA will continue to work with industry to identify additional
actions to reduce the average number of review cycles and the percent
of 510(k) submissions for which an AI Letter is sent. FDA has already
taken steps to address some of the issues identified in this analysis.
We are working to provide greater predictability for industry by
communicating justified changes in data requirements more quickly and
transparently. We recently issued a draft Standard Operating Procedure
for ``Notice to Industry'' Letters,\20\ which provides a format for
communicating changes expeditiously within the existing Good Guidance
Practices framework. FDA is also enhancing training for FDA staff and
industry, which is aimed at reducing inappropriate requests for
additional information and helping sponsors understand when they are
required to submit data.

Letters'' (August 2011), available at http://www.fda.gov/downloads/

---------------------------------------------------------------------------
Through these and other steps we are taking to address weaknesses
in the 510(k) program, FDA aims to reduce the amount of time to
clearance for 510(k) devices, while ensuring that we maintain the same
standards of safety and effectiveness. It is our hope that taking
actions to increase submission quality and avoid inappropriate requests
for additional information will prevent avoidable delays and reduce
review times, which will, in turn, get safe and effective devices to
market faster.
Question 8. I'm concerned about what appears to be a lack of
urgency on the part of FDA with respect to newer, better therapies to
treat diabetes and obesity. These are diseases that increasingly
threaten our Nation's health care system--diabetes alone accounts for
one-third of Medicare costs and almost 80 million Americans have pre-
diabetes (on top of the 25.8 million Americans already living with the
disease).
My home State of Tennessee has one of the highest obesity rates at
being over 30 percent, and obesity is nearing epidemic proportions
across the country. We are at a time in our history where reports by
distinguished journals of medicine and health experts say today's
children are likely to be the first generation to live shorter, less
healthy lives than their parents. This is a health care crisis. One of
the biggest reasons for this is the growing childhood obesity problem,
and the increasing rates of diseases normally associated with adults
such as Type 2 diabetes, heart disease, and other chronic illnesses.
What are you doing to encourage the development of new therapies to
treat these diseases? Are you considering using the authority given to
the FDA under REMS to follow the drugs closely after approval?
It's essential that we take strong steps to prevent the spread of
diabetes through better nutrition and physical fitness, but we must
also encourage innovation of better therapies to treat diabetes and
obesity. What are you doing to support that needed innovation?
Answer 8. FDA recognizes the rising incidence of diabetes in the
United States and the need for innovative therapies to treat this
chronic condition. We currently have 11 different drug classes to treat
Type 2 diabetes, and many of these newer therapies became available
within the past 5 to 7 years, despite the withdrawal of troglitazone in
1999 for liver toxicity and the cardiovascular safety concerns of
rosiglitazone presented at two public meetings in 2007 and 2010.
These safety concerns serve as a reminder that while the goal is to
ensure effective treatments for diabetes to the American public, these
therapies must be carefully studied to ensure that side effects do not
outweigh the benefits of blood sugar control, especially when
physicians and patients have many classes of drugs from which to
choose. For this reason, FDA held a 2-day public advisory committee
meeting in July 2008 to seek scientific advice on the design of
diabetes drug development programs to evaluate the cardiovascular
safety of these drugs. In December 2008, a Guidance for Industry was
published, outlining FDA's requirements for new anti-diabetic
therapies: ``Diabetes Mellitus--Evaluating Cardiovascular Risk in New
Anti-diabetic Therapies to Treat Type 2 Diabetes.''
The Guidance calls for more extensive evaluation of new anti-
diabetic therapies to help to ensure that these therapies are safe and
effective. However, to avoid delay in approving innovative therapies,
FDA has employed new authorities under the FDA Amendments Act of 2007
FDAAA and required companies to collect such data through post-
marketing studies. Since December 2008, FDA has approved four new drugs
for the treatment of Type 2 diabetes.
Similarly, we recognize that obesity poses a serious public health
problem to this country. In 2007, FDA issued a draft guidance document
for industry entitled ``Developing Products for Weight Management.''
FDA is committed to working with pharmaceutical companies to bring new
obesity drugs with favorable benefit-risk profiles to the market, but
obesity has been a difficult area in which to develop drugs with
favorable benefit-to-risk profiles. Two obesity drugs and one dietary
supplement have been withdrawn from the market because they increased
blood pressure and, in the case of the two obesity drugs, were
documented to increase the incidence of stroke and/or heart attacks.
FDA took another class of obesity drugs off the market because they
increased the risk for heart valve disease, in some cases, requiring
patients to have open heart surgery to replace their damaged valve. An
additional drug to treat obesity that was recently approved by the
European Medicines Agency (EMA), but not by FDA, was later withdrawn
from the European market due to an increased risk of suicide. We must
make sure that any new products to treat obesity are safe, while taking
into account the public health impact of obesity.
FDA is planning a scientific meeting to discuss obesity drugs and
cardiovascular safety, and we are also planning to attend stakeholder
meetings involving pharmaceutical companies, patient advocacy groups,
and obesity experts to discuss development of obesity drugs. We expect
these meetings to be very helpful to industry in developing drug
products to treat obesity.
As FDA evaluates new drugs for the treatment of obesity, we will
carefully consider the role of Risk Evaluation and Mitigation
Strategies (REMS) and required post-marketing studies to ensure that
the benefits of the drug outweigh its risks.
Question 9. In the last PDUFA bill (FDAAA), the critical path
partnerships were authorized and FDA has awarded collaborative
agreements to several entities. It is my understanding that one of
these collaborations has made it possible for the industry to share
their data from clinical trials for Alzheimer's disease. From FDA's
perspective, what has been learned and will other disease databases
result from this work?
Answer 9. One of the greatest challenges facing biomedical sciences
in the 21st century is the development of better treatments for
neurodegenerative diseases. The two most prevalent of these,
Alzheimer's disease and Parkinson's disease, exert a heavy and growing
burden on our society. Our lack of knowledge about the specific cause
or causes of either disease is a major obstacle to the development of
new treatments that have the potential to cure or prevent these
devastating and tragic diseases.
The Coalition Against Major Diseases (CAMD) was formed by the non-
profit Critical Path Institute, in cooperation with FDA, patient
organizations, the medical products industry, and the Engelberg Center
for Health Care Reform at the Brookings Institution. CAMD's focus is to
develop new tools and methods that can be applied during the
development of new treatments for neurodegenerative diseases, focusing
on Alzheimer's and Parkinson's first. In CAMD, data integration and
sharing are planned to create a quantitative disease-progression model
that includes biomarkers that potentially identify discrete patient
subsets of the disease. CAMD, working with the Clinical Data
Interchange Standards Consortium, has developed and published data
standards for Alzheimer's clinical trials. CAMD has been able to pool
data from 11 clinical trials conducted by seven pharmaceutical
companies into an Alzheimer's disease database that describes the
natural history of the disease in over 4,000 patients. This database,
along with the mathematical models of the disease available to
researchers in the field, will allow clinical investigators to more
accurately predict the outcome for a given clinical trial, the length
of time needed for the trial, how many patients should be enrolled in
the trial, and how genetic subsets of the population might respond.
Hopefully, CAMD efforts will help reduce the failures in development of
new drugs for Alzheimer's and will be a model for the establishment of
other disease databases.
Question 10. The EU has made a significant long-term commitment to
advancing the science that supports drug development with the goal of
increasing investment and productivity for the biotech industry in
Europe. I understand that they committed 1 billion euros and the
industry is matching it with in kind contributions. They proclaim that
this is the largest public private partnership in the world. What can
the United States do to protect its investment in biotechnology? In
this country, is the industry actively participating in the critical
path public-private partnerships? Can we do more to encourage their
participation?
Answer 10. Yes. Industry is participating in Critical Path and
other public-private partnerships, but there is much more we can do.
Government investment in regulatory science, combined with FDA-driven
policy approaches to promote medical product innovation, are critical
to maintain U.S. competitiveness in an increasingly globalized market.
The closest counterpart to the European IMI is the Critical Path
Initiative, which is currently funded at a level of $18 million
annually. FDA's new Regulatory Science Initiative seeks to build on the
Critical Path program by expanding awareness and laying out a strategy
for making investments in key applied scientific areas that will
facilitate increasing innovation and safer and more efficacious medical
products. In addition, the Regulatory Science Initiative addresses the
entire product lifespan, from preclinical through post-market,
including assessment of real-world performance of drugs, patient
utilization and communication, and outcomes.
On October 5, 2011, FDA released a blueprint to lay out key policy
suggestions that, in conjunction with regulatory science investments,
will drive medical product innovation. The goal is to enhance both the
health of the American people and the health of the medical product
industry, a key component of our technology sector, and an area where
the United States still leads in innovation and creativity.
Public-private partnerships between FDA, other government agencies,
industry, and academia are a central component of both our innovation
and regulatory science strategies. But government investments in the
form of dollars and sound cross-agency collaborations and policies must
be made to maintain U.S. leadership in the biotechnology sector. In our
extensive discussions with business leaders from both large and small
medical product development companies, it is clear that companies want
to collaborate and will invest in these important areas, both in
dollars and through partnering--if they see a significant and sustained
commitment from the U.S. government to support the infrastructure,
science, and policies that create an environment poised for innovation
and global competitiveness.
In 2007, Congress created the Reagan-Udall Foundation as a vehicle
for public-private partnerships in regulatory science. The Foundation
has been able to initiate a few regulatory science partnerships, but
absent the funding support initially contemplated has not been able to
build a robust scientific program.
Question 11. One area of focus in the PDUFA V proposal is on
advancing Regulatory science, specifically, as stated by the Agency,
Enhancing Regulatory Science and Expediting Drug Development. What
process will you use to set priorities for how to enhance regulatory
science? Will the industry and patients have voices in setting these
priorities?
Answer 11. FDA is recommending a set of specific review program
enhancements that will strengthen the science and expedite drug
development as part of the PDUFA V recommendations. Under PDUFA V FDA
would commit to accomplish all of these enhancements and not prioritize
among them. These PDUFA V recommendations are the product of FDA's
extensive negotiations with industry and parallel consultations with
patients and other stakeholders from April 2010 through May 2011 and
reflect the priorities identified by these groups. The initiatives
included in these recommendations are directly related to areas where
specific near-term advances can be made to reduce the scientific
uncertainty, business risk, and in some cases reduce the time and other
resources required for new drug development.
These enhancements include:
1. Promoting Innovation Through Enhanced Communication Between FDA
and Sponsors During Drug Development;
2. Methods for meta-analysis;
3. Biomarkers and pharmacogenomics;
4. Use of patient-reported outcomes (PROs); and
5. Development of drugs for rare diseases.
As stated below, each of these addresses specific challenges with
the current drug development and review processes.
1. Promoting innovation through enhanced communication between FDA
and sponsors during drug development:
Problem: New drug innovators operate at the cutting edge
of science but may have less experience with FDA regulatory
requirements to ensure substantial evidence of safety and efficacy.
Timely communication between FDA and sponsors during development helps
to ensure efficient and effective drug development, and also helps
achieve FDA's mission by making safe and effective new drugs available
in a timely manner.
Proposed Recommendation: FDA will develop a dedicated drug
development communication and training staff in CDER and CBER, focused
on enhancing communication between FDA and sponsors during development.
The liaison staff will conduct a range of tasks including
identification and dissemination of best practices for enhanced
communication and development of training programs for review staff.
FDA will publish a guidance describing its philosophy on timely
interactive communications and the scope of appropriate interactions
with sponsors during drug development.
Methods for meta-analysis:
Problem: Currently, there is no consensus on best
practices in conducting a meta-analysis. FDA is often forced to
evaluate meta-analyses of published or unpublished clinical trials,
usually addressing a high visibility safety problem for an approved
product. Review and evaluation of a meta-analysis, sometimes conducting
the Agency's own meta-analysis, can exceed FDA's current scientific and
computational capacity.
Proposed Recommendations: FDA will develop a dedicated
review team to evaluate scientific methods, limitations in the methods,
and potential best practices for the conduct of meta-analyses. FDA will
also hold a public meeting on the current and emerging approaches to
meta-analyses, and develop guidance on FDA's intended approach to meta-
analysis in the regulatory review process and in regulatory
decisionmaking.
3. Biomarkers and pharmacogenomics:
Problem: Pharmacogenomics and the application of qualified
biomarkers have the potential to decrease drug development time.
Qualified biomarkers can enrich clinical trials by demonstrating
benefits, establishing unmet medical needs, and identifying patients
with a predisposition to adverse events, and regulatory submissions of
this type have increased recently, outstripping FDA capacity for
review.
Proposed Recommendations: FDA will increase clinical,
clinical pharmacology, and statistical capacity to adequately address
submissions that propose to utilize biomarkers or pharmacogenomic
markers in development programs. FDA will hold a public meeting to
discuss potential strategies to facilitate scientific exchanges in
regulatory and non-regulatory contexts.
4. Use of patient-reported outcomes (PROs):
Problem: Study endpoint assessments are increasingly an
important part of successful drug development, requiring rigorous
evaluation and statistical design and analysis. However, there is a
high study-failure rate for PRO endpoints not qualified in advance of
phase 3 trials. Early consultation could ensure that endpoints are
well-defined and reliable.
Proposed Recommendations: FDA will enhance clinical and
statistical capacity to address submissions involving PROs and other
endpoint assessment tools, including providing IND consultation, and
will convene a public meeting to discuss PRO qualification standards,
new endpoint measurement theory, and implications for multinational
trials.
Development of drugs for rare diseases:
Problem: Regulatory oversight of rare disease drug
development is complex and resource intensive. Recent trends in orphan
designations may indicate an expected future increase in
investigational activity and marketing applications for orphan
products.
Proposed Recommendations: FDA will develop guidance
related to advancing and facilitating development of drugs for rare
diseases, increase outreach to patient representatives and industry
regarding development of these drugs, convene a public meeting to
discuss complex issues in clinical trials for studying drugs for rare
diseases, and develop and implement training for all review staff on
development and review of drugs for rare diseases as part of the core
reviewer curriculum.
In August 2011, FDA released its Strategic Plan for Regulatory
Science. The strategic plan describes the Agency's intent to
collaboratively enhance the process for developing and evaluating
promising new products and defines the Agency's highest cross-cutting
priorities linking to several themes contained in a report from CDER as
well as other reports across the Agency.
CDER released its draft report entitled ``Identifying CDER's
Science and Research Needs'' in July 2011. This report is an essential
first step to formulating regulatory science priorities, which will
guide development of a CDER regulatory science and research agenda.
Release of the Science and Research Needs Report is the culmination of
an exhaustive process that started with interviews of over 200
reviewers and scientists from across CDER--those who are closest to the
regulatory processes and the regulatory science needed to support those
processes. The comprehensive report on regulatory science and research
needs was compiled from these discussions.
We have opened a docket to solicit critical input from our external
stakeholders in industry, academia, and patient organizations, and our
governmental partners, on CDER's draft report ``identifying CDER's
Science and Research Needs,'' and to solicit input on additional
critical science needs, ongoing efforts to address them, and creative
mechanisms for collaboration. Further, we will be continuing to ask our
reviewers for input and are making the identification of critical
regulatory science challenges an ongoing process. We have provided our
reviewers and scientists a direct route to comment on our science needs
document and to add new challenges. This mechanism for horizon scanning
will provide an ongoing system to identify emerging regulatory science
issues. While we compile external and internal comments, we will be
examining our current regulatory science and research portfolio to
identify areas where progress is being made and to identify critical
gaps that are not being adequately addressed.
Question 12. Patient response and satisfaction with treatment is an
area that often is left out of our discussions yet new medicines should
keep patient benefit front and center. I understand that the Critical
Path Institute is the Agency's partner working with the industry to
develop standardized, validated questionnaires and electronic diaries
to be used in testing new drugs and devices. How many Agency scientists
are working with them and would more resources and FTE speed up this
important work?
Answer 12. Study endpoint assessments, known as patient-reported
outcomes (PROs), are an important part of successful drug development.
PROs are critical in understanding the drug benefits and harm from the
patients' perspectives. However, PROs, like other outcome assessments,
require rigorous development to ensure validity and reliability to
support claims of clinical benefit.
Early consultation between FDA and outcome assessment developers
can ensure that endpoints are well-defined and reliable. In addition to
the Critical Path Institute, FDA is working with several other public
and private partners, including the Foundation for the National
Institutes of Health and individual NIH institutes to develop
standardized questionnaires, clinician assessments, and electronic
diaries under the qualification pathway. Qualification is the
regulatory conclusion that within the stated context of use, the
results of assessment with a particular tool can be relied upon to have
a specific interpretation and application in drug development and
regulatory decisionmaking and labeling. Outcome assessments that
undergo qualification will be publicly available, eliminating the need
for multiple drug sponsors to repeat this critical work. Therefore,
these activities promise to make medical product development and
clinical trials more informative and efficient.
A dedicated FDA staff provides review for PRO measures, not only
under the qualification pathway (e.g., with the Critical Path
Initiative), but also in the context of specific investigational drugs.
Therefore, the number of full-time employees (FTEs) currently dedicated
to this work is difficult to calculate. It is clear, however, that the
Agency does not have the capacity to meet the current demand for both
of these review processes. In CDER, the primary review team for PRO
measures and other clinical assessment tools includes a total of seven
individuals, including the director and a temporary fellow. The team
reviews the tools in conjunction with the clinical reviewers in the
Office of New Drugs (OND) and also provides consultation and advice to
the submitters.
FDA recently announced its proposed recommendations for PDUFA V. We
propose several measures to enhance regulatory science and expedite
drug development, including a proposal to increase clinical and
statistical staff capacity to more efficiently and effectively respond
to submissions that involve PROs and other outcome assessment tools. We
also propose a public meeting to discuss FDA's qualification standards
for development tools, new measurement theory, and implications for
multi-national trials.

Question 1. For each of the FDAAA review performance goals, what
was the average length of response time for the Agency? What was the
average length of response times that did not fall within the
performance goals?
Answer 1. Under performance timelines associated with PDUFA IV,
which was enacted as part of the FDA Amendments Act of 2007 (FDAAA),
FDA has committed to review and act on 90 percent of original New Drug
Applications (NDAs) and Biologics License Applications (BLAs) \21\
within 10 months of receipt for standard applications and 6 months for
priority-designated applications.\22\ The performance level of 90
percent was chosen in acknowledgement of the fact that in some cases it
is appropriate that FDA continue its review of an application past the
goal date to address important outstanding issues. In fact, in some
cases FDA continues its review past the PDUFA goal date to address
remaining issues so that the application can be approved on that review
cycle and thus avoid the need for a second review cycle that would be
triggered by issuance of a complete response letter by the PDUFA goal
date. This can allow a drug to be available to patients in a more
timely manner while allowing the Agency to still meet its 90 percent
goal for actions.
---------------------------------------------------------------------------
\21\ Note that FDA relied on data captured by PDUFA and MDUFA
reporting requirements to provide these responses. Therefore, they do
not include data on applications reviewed by the Agency that are not
subject to user fees.
\22\ It should be noted that a review action does not imply
application approval. NDAs and BLAs submitted for FDA review may
receive a complete response that does not allow marketing approval, but
identifies the application deficiencies that would need to be addressed
in order to obtain marketing approval.
---------------------------------------------------------------------------
As of March 31, 2011, FDA's average review time for priority NDAs
and BLAs filed in fiscal year 2010 and reaching a regulatory action is
approximately 6.6 months,\23\ compared with 5.8 months for priority
applications filed in fiscal year 2006. As of March 31, 2010, the
average review time to regulatory action for standard original NDAs and
BLAs filed in fiscal year 2010 is 10.3 months,\24\ compared with 10.6
months for standard applications filed in fiscal year 2006.
---------------------------------------------------------------------------
\23\ FDA was able to meet its PDUFA goals 100 percent of the time,
even though the review time on average is 6.6 months, because the
Agency may extend goal dates by 3 months when the sponsor submits a
major application amendment within 3 months of the goal due date.
Therefore, some priority goats may be extended to 9 months, resulting
in the higher average,
\24\ This number reflects the average review time for standard
applications as of March 31, 2011, and final performance can be
expected to change slightly, given that 25 percent of fiscal year 2010
standard implications were still pending within goal as of this date.
---------------------------------------------------------------------------
We are pleased to report that as of March 31, 2011, for
applications received in fiscal year 2010, FDA has met its PDUFA review
goals 100 percent of the time for priority applications and 97 percent
of the time for standard applications, with 5 percent of priority
applications and 25 percent of standard applications still pending FDA
review, all within their PDUFA goal.\25\
---------------------------------------------------------------------------
\25\ For more information on PDUFA performance, see the 2010 report
to Congress: http://www.fda.gov/downloads/AboutFDA/ReportsManualsForms/
Reports/UserFeeReports/Perform
anceReports/PDUFA/UCM243358.pdf. Please note that the data as of March
31, 2011, may differ from the figures in the Performance Report, which
reflect more current data as of September 30, 2010.
---------------------------------------------------------------------------
It is important to note that the PDUFA goal for an application may
be extended by up to 3 months if the sponsor submits a major amendment
(e.g., a new clinical study report) during the last 3 months of review.
If FDA completes its review and issues its action on or before the
extended goal date, this is counted as having met the PDUFA goal even
though the overall time required for the review may be 9 months
(priority) or 13 months (standard). This provision is included in the
PDUFA performance goals to avoid an unnecessary second cycle of review
in cases where the clock extension can allow FDA to complete its review
of the major amendment and approve the application in that review
cycle. This explains why the average review time for a cohort of
applications can be greater than 6 (priority) or 10 (standard) months,
even if all the applications in the cohort are acted on or before their
PDUFA goal date.
Question 2. Since 1993, among all regulatory actions that count as
meeting PDUFA performance goals, what percentage were:
a. Approvals?
b. Not approved?
c. ``Complete Response'' letters?
Answer 2. For all original applications \26\ filed and action taken
within PDUFA performance goals by FDA from fiscal year 1993 through
fiscal year 2011, as of July 2011, 74 percent of the products have
received Approval actions,\27\ which include Approval and Tentative
Approval, and 26 percent of the products have only received Non
Approval actions, which include Not Approvable, Approvable, Withdrawn
after filing, and Complete Response.
---------------------------------------------------------------------------
\26\ This response assumes that the term ``original applications''
is defined as original Filed NDAs and BLAs as well as resubmissions.
This does not include supplements.
\27\ We define the Approval-Non Approval determination on the
current status, as applications currently with a Non Approval action
can still be approved in the future.
---------------------------------------------------------------------------
It should be noted that as of August 2008, FDA replaced the
``Approvable'' regulatory action and the ``Not Approvable'' regulatory
action with the ``Complete Response'' regulatory action. We cannot
distinguish between ``Not Approved'' and ``Complete Response'' as
questioned and so we compared products that have received Approval
actions compared to products that have not received Approval actions.
Since every review cycle requires a regulatory action, any application
that has not received an Approval action has received a Non Approval
action.
Question 3. If the Agency did not count ``complete response''
letters, or ``approvable'' or ``not approvable'' responses towards the
performance goals, how would the reported performance goals since 1993
be adjusted? In short, what percentage of the time does FDA complete
its review of an application--approve or not approve--during the first
review cycle?
Answer 3. Each review cycle requires a regulatory action. Approval
actions include Approval and Tentative Approval, and Non Approval
actions include Not Approvable, Approvable, Withdrawn after filing, and
Complete Response.\28\ Thus, the answer to this question is the same as
above.
---------------------------------------------------------------------------
\28\ As stated above, in August 2008. FDA replaced the
``Approvable'' regulatory action and the ``Not Approvable'' regulatory
action with the ``Complete Response'' regulatory action.
Question 4. With respect to pre-market applications, of the device
PMAs acted upon by the FDA and counted towards the reported user fee
performance goals, what percentage of the reported performance goals
---------------------------------------------------------------------------
were:
a. Approvals?
b. Approvables?
c. Not Approvables?
d. Denials?
e. Withdrawn applications?
Answer 4. [Note: Numbers were rounded; therefore percentages don't
always equal 100.]

Question 7. Beginning in 1992 and for every year thereafter to
present, please report on the average time for the review of a human
drug application (NDAs, BLAs, and supplements). For the same time
period, please report on the percentage of human drug applications
approved on a first cycle review.
Answer 7. Please see the chart attached as Appendix 1. PDUFA was
first enacted in 1992, and 1993 represents the first year we reported
data. Thus, we have provided data from 1993 to present.
Question 8. Has the increase in user fees in MDUFA II translated
into more timely or faster review periods? Has the increase in user
fees in MDUFA II resulted in an increase in the number of FDA-approved
or cleared products for patients? Has the increase in fees resulted in
fewer review cycles per submission compared to previous user fee
agreements?
Before addressing the performance issues raised in this question,
it is important to note the context for the increase in user fees that
took place as a result of the enactment of MDUFA II in 2007. Those user
fee increases were intended to cover the anticipated increase in the
cost of maintaining FDA device review staffing levels that were
achieved at the end of MDUFA I, which FDA believed would be sufficient
to meet the performance goals regarding timely decisionmaking. The
increases were not intended to achieve any particular outcomes of those
decisions, such as product approvals or clearances.
The average review time for original PMAs and Panel Track
Supplements (supplements for a new indication, which contain new
clinical data) has improved from 11 months in fiscal year 2005 to 8
months in fiscal year 2009 (Tier 1 goal: 60 percent of original PMAs
and Panel Track Supplements in 180 days). This is a 42 percent decrease
in days from 2005 to 2009.
With respect to the Tier 2 goal for PMAs and Panel Track
Supplements (90 percent in 295 days), there has been a 48 percent
decrease in days from 2005 to 2009. These improvements are the result
of more efficient submission management due to additional resources
provided through MDUFA and process improvements implemented by FDA.
Although FDA is meeting its 510(k) performance goals under MDUFA,
overall time to decision (i.e., FDA review time plus industry response
time) for 510(k) submissions has increased over the past 10 years, due
primarily to an increase in the number of review cycles and in the
amount of time companies take to respond to requests for additional
information.
We recognize our role in this and are taking steps to address it.
The two reports we released publicly in August 2010, with our analyses
and recommendations, showed that we have not done as good a job
managing our pre-market review programs as we should and that we need
to take several critical actions to improve the predictability,
consistency, and transparency of these programs.
For example, we have new reviewers who need better training. We
need to improve management oversight and standard operating procedures.
We need to provide greater clarity for our staff and for industry
through guidance about key parts of our premarket review and clinical
trial programs and how we make benefit-risk determinations. We need to
provide greater clarity for industry through guidance and greater
interactions about what we need from them to facilitate more efficient,
predictable reviews. We need to make greater use of outside experts who
understand cutting-edge technologies. And we need to find the means to
handle the ever-increasing workload and reduce staff and manager
turnover, which is almost double that of FDA's drugs and biologics
centers.
In January 2011, FDA announced a Plan of Action that included 25
specific actions that we would take this year to improve the
predictability, consistency, and transparency of our premarket
programs. The following month, we announced our Innovation Initiative,
which included several proposals to help maintain the position of the
United States as the world's leader in medical device innovation,
including the creation of a new approach for important, new
technologies called the Innovation Pathway.
Since then, we have announced additional efforts to improve our
premarket programs, including actions to improve our program for
clinical trials and the Investigational Device Exemption (IDE) program.
The actions we are taking can be grouped into three main areas of
emphasis:
Create a culture change toward greater transparency,
interaction, collaboration, and the appropriate balancing of benefits
and risks;
Ensure predictable and consistent recommendations,
decisionmaking, and application of the least-burdensome principle; and
Implement efficient processes and use of resources.
Specific steps that we are taking, many of which are supported by
industry, include:
Issuing guidance clarifying the criteria used to make
benefit-risk determinations a part of device premarket decisions to
provide greater predictability and consistency and apply a more
patient-centric approach by considering patients' tolerance for risk in
appropriate cases (draft guidance issued August 15, 2011);
Creating standard operating procedures for when a reviewer
can request additional information regarding a premarket submission and
at what management level the decision must be made to provide greater
predictability, consistency, and the appropriate application of the
least-burdensome principle by reducing the number of inappropriate
information requests (Standard Operating Procedures issued November
2011).
Developing a range of updated and new guidances to clarify
CDRH requirements for predictable, timely, and consistent product
review, including device-specific guidance in several areas such as
mobile applications (draft guidance released July 19, 2011) and
artificial pancreas systems (to be completed by the end of 2011);
Revamping the guidance development process through a new
tracking system and, to the extent resources permit, core staff to
oversee the timely drafting and clearance of documents (to be completed
by the end of 2011);
Improving communication between FDA and industry through
enhancements to interactive review (some of these enhancements will be
in place by the end of 2011);
Streamlining the clinical trial and IDE processes by
providing industry with guidance to clarify the criteria for approving
clinical trials, and criteria for when a first-in-human study can be
conducted earlier during device development to create incentives to
bring new technologies to the United States first (guidance to be
issued November 2011) (IDEs are required before device testing in
humans that involve significant risks may begin, and they ensure that
the rights of human subjects are protected while gathering data on the
safety and efficacy of medical devices);
Implementing internal business process improvements to
ensure that decisions are made by the appropriate level of management,
that decisions are made consistently and efficiently, and that we
appropriately apply the least-burdensome principle. For example,
CDRH created the internal Center Science Council to actively
monitor the quality and performance of the Center's scientific programs
and ensure consistency and predictability in CDRH scientific
decisionmaking (Center Science Council established March 31, 2011);
Creating a network of experts to help CDRH resolve complex
scientific issues, which will ultimately result in more timely reviews.
This network will be especially helpful as FDA confronts new
technologies (Standard Operating Procedures issued September 30, 2011);
Instituting a mandatory Reviewer Certification Program for
new reviewers (program launched September 2011);
Instituting a pilot Experiential Learning Program to
provide review staff with real-world training experiences as they
participate in visits to manufacturers, research, and health care
facilities, and academia (to begin in early 2012);
Providing industry with specific guidance on how to ensure
the quality and performance of clinical trials while applying the
least-burdensome principle, and thereby conduct studies that are more
likely to support the approval of their products (guidance released
August 15, 2011); and
Streamlining the de novo review process, the pathway by
which novel, lower-risk devices without a predicate can come to market
(draft guidance released September 30, 2011).
A recent FDA analysis \29\ shows that poor submission quality is a
major contributor to the increase in total review times. The most
common deficiencies included:
---------------------------------------------------------------------------
\29\ CDRH, ``Analysis of Premarket Review Times Under the 510(k)
Program'' (July 2011), available at http://www.fda.gov/AboutFDA/
CentersOffices/CDRH/CDRHReports/ucm263385.htm
#5.
Inadequate device descriptions;
Discrepancies throughout the submission;
Failure to address necessary information as outlined in
guidance documents;
Problems with the proposed indications for use;
Completely missing performance testing; and
Completely missing clinical data.
In addition, sponsors' failure to address deficiencies identified
in first-round AI Letters is a major contributor to the increase in
total review times. For example, 65 percent of the time, FDA sent a
second-round AI Letter because the sponsor failed to submit information
requested in the first AI Letter.
FDA has already taken steps to address some of the issues
identified in this analysis. We are working to provide greater
predictability for industry by communicating justified changes in data
requirements more quickly and transparently. We recently issued draft
Standard Operating Procedures for Notice to Industry Letters,\30\ which
provides a format for communicating changes more quickly within the
existing Good Guidance Practices framework. FDA is also enhancing
training for staff and industry, which is aimed at reducing
inappropriate requests for additional information and helping sponsors
understand when they are required to submit data. We will continue to
work with industry to identify additional actions to reduce the average
number of review cycles and the percent of 510(k) submissions for which
an AI Letter is sent.
---------------------------------------------------------------------------
\30\ CDRH, ``Standard Operating Procedure for `Notice to Industry'
Letters'' (August 2011), available at http://www.fda.gov/downloads/
MedicalDevicesRegulationandGuidance/Guidance
Documents/UCM259172.pdf.
---------------------------------------------------------------------------
Through these and other steps we are taking to address weaknesses
in the 510(k) program, FDA aims to reduce the total time to clearance
for 510(k) devices, while assuring that we maintain the same levels of
safety and effectiveness. It is our hope that taking actions to
increase submission quality and avoid inappropriate requests for
additional information will prevent avoidable delays and reduce total
time to decision, which will, in turn, get safe and effective devices
to market faster.
With regard to PMA applications, FDA's internal analysis found
that, for those PMAs that were not reviewed within the performance
goals, the main reasons for the longer review times were:
Poor quality clinical studies, such as clinical trial
execution issues and problematic data analyses;
Reviewer turnover, especially changing medical officers
and branch chiefs; and
Taking a PMA to an FDA advisory committee. (In general,
all PMAs for the first-of-a-kind device are taken before the
appropriate advisory panel for review and recommendations. The
preparation for an FDA advisory committee involves significant calendar
time and review team resources.)
Question 9. Beginning in 2007, and for every year thereafter, what
percentage of products seeking to rely solely on foreign clinical trial
data for approval have been approved without requiring any further
clinical requirements, such as domestic clinical trials? Since
enactment of FDAMA in 1997, how many products have been approved based
just on foreign clinical trial data?
Answer 9. We are unable to provide statistics in response to this
question, as FDA does not track applications on the basis of the source
of the clinical data.
FDA does not require studies to support drug or device approvals to
be conducted in the United States. Data collected from other countries
can be used to support a product's safety and effectiveness. Foreign
studies performed under an IND or IDE must meet the same requirements
of 21 CFR part 312 or 21 CFR part 812, respectively, that apply to U.S.
studies conducted under an IND or IDE. The acceptance of foreign
clinical studies not conducted under an IND or IDE, as support for a
marketing application, is generally governed by 21 CFR 312.120 and 21
CFR 814.15.
A marketing application based solely on foreign clinical data
meeting U.S. criteria for marketing approval may be approved if:
the foreign data are applicable to the U.S. population and
U.S. medical practice;
the studies have been performed by clinical investigators
of recognized competence: and
the data may be considered valid without the need for an
on-site inspection by FDA or, if FDA considers such an inspection to be
necessary, the Agency can validate the data through an on-site
inspection or other appropriate means.
The following are examples of drugs approved on the basis of
foreign data:
Eloxatin (oxaliplatin) for injection--was approved under
FDA's accelerated approval regulations, based exclusively on foreign
clinical data from trials conducted in Israel, Singapore, Australia,
and 17 European countries.
Aggrenox (aspirin/extended-release dipyridamole)--Capsules
were approved based exclusively on foreign clinical data from trials
conducted in 13 European countries.
The following are examples of devices approved on the basis of
foreign data:
The FC2 Female Condom was approved using clinical data
from investigations conducted in South Africa.
The Boston Scientific Corp. Express LD Iliac Premounted
Stent System was approved using clinical data generated from trials in
the Netherlands, Belgium,
the Czech Republic, Poland, and Canada. In an effort to ensure that FDA
was open to the OUS (outside the United States) clinical data being
used to support PMA
approval, the sponsor had several pre-IDE, interactions with FDA. In
these pre-
submission interactions, agreement was reached on the retrospective
performance goal that would be applied to the study data. In addition,
the review team worked interactively with the sponsor through a number
of minor pre-clinical and clinical issues prior to submission of the
PMA.
Question 10. The Commissioner's testimony states that, ``FDA aims
to review priority new molecular entities more quickly--6 months vs. 10
months for standard drugs'' and that ``Priority NMEs represent truly
innovative medicines generally targeted at severe illnesses with few or
no available therapeutic options.'' Is the Agency meeting the 6-month
and 10-month review targets for priority and standard NMEs? The
testimony also states that the Agency is ``on track for approving a
historically high percentage of priority NMEs for 2011.'' What is the
percentage the Agency is on track to approve with respect to both
priority and standard NMEs for 2011?
Answer 10. As of March 31, 2011, for applications received in
fiscal year 2010, FDA has met its PDUFA goals 100 percent of the time
for priority applications and 97 percent of the time for standard
applications, with 5 percent of priority applications and 25 percent of
standard applications of these applications still pending FDA review,
all within their PDUFA goal.\31\ This performance exceeds our goal to
review and act on 90 percent of original NDAs and BLAs \32\ within 10
months of receipt for standard applications and 6 months for priority-
designated applications.\33\
---------------------------------------------------------------------------
\31\ For more information on PDUFA performance, see the 2010 report
to Congress: http://www.fda.gov/downloads/AboutFDA/ReportsManualsForms/
Reports/UserFeeReports/PerformanceReports/PDUFA/UCM243358.pdf. Please
note that the data as of March 31, 2011 may differ from the figures in
the Performance Report, which reflect more current data as of September
30, 2010.
\32\ Note that FDA relied on data captured by PDUFA and MDUFA
reporting requirements to provide these responses. Therefore, they do
not include data on applications reviewed by the Agency that are not
subject to user fees.
\33\ It should be noted that a review action does not imply
application approval. NDAs and BLAs submitted for FDA review may
receive a Complete Response that does not allow marketing approval, but
identifies the application deficiencies that would need to be addressed
in order to obtain marketing approval.
---------------------------------------------------------------------------
As of July 2011, of the six priority applications received and
acted upon in fiscal year 2011, four of which were NMEs, all were
approved. This number could increase as current pending priority NME
applications mature to their review performance goal dates. It is
premature to report on performance for fiscal year 2011 standard NME
applications.
Question 11. The Commissioner's testimony states that ``so far this
year, FDA has approved 21 new, groundbreaking medicines . . . '' What
percentage do these 21 medicines represent of the total applications
submitted for review? What percentage do these 21 medicines represent
of the total approvals for 2011?
Answer 11. Approval figures in the response to this question are
for calendar year (CY) 2011. As of July, there were 63 total Approvals,
of which 21 were for NMEs/new BLAs. These NMEs/new BLAs represent 33
percent of the total Approvals. These figures will change as additional
applications are approved during the remaining months of CY 2011.
FDA generally reports PDUFA performance in terms of cohorts of
applications received in a given fiscal year. Because FDA is still
receiving applications in CY 2011 and since there are still pending
applications in the fiscal year 2011 cohort that are within their PDUFA
goal date, it would be premature to otherwise assess program
performance based on CY or fiscal year 2011 information. The most
recent measure of program performance is contained in FDA's response to
Question 12 below.
Question 12. Please report on the total number of human drug
applications (NDAs, BLAs, and supplements) received by FDA each year
beginning in 2000 to present. Please report on the total number of
applications approved on first cycle review and what percentage of
total applications and total approvals they represent for each year.
Answer 12. Please refer to the data in the tables below. Because
the fiscal year 2011 cohort of applications has not yet matured (i.e.,
applications in this cohort are still pending and within their PDUFA
goal date), FDA is reporting on the receipt cohorts from fiscal year
2000 through fiscal year 2010. We have also provided the data by
priority and standard applications as this is typically how FDA reports
data on the performance of the drug review program.
You had also requested the percentage of total approved
applications in each year that were approved on the first cycle. We
could not provide a valid statistic in response to this request. Total
approvals in a given year include approvals of resubmitted
applications. As requested, this statistic could never be 100 percent
since the denominator of total approvals contains approvals of
resubmitted applications that could never be counted in the numerator
of first cycle approvals.

Question 13. Many concerns have arisen regarding the regulatory
certainty of the FDA's review process for drugs and devices. How could
FDA better articulate requirements and develop more predictable
approaches so that sponsor applications have a higher likelihood of
first cycle approvals? How can FDA provide more timely and transparent
guidance to sponsors regarding expectations with regard to compliance
with the Agency's regulations?
Answer 13. FDA has been taking action for some time to help drive
innovation in new drug development. In 2004, FDA launched its Critical
Path Initiative, FDA's national strategy to help advance pharmaceutical
innovation. Our long-term efforts are showing positive signs, and FDA
will continue to support the scientific community to advance new drug
development.
The key challenges facing scientific progress and innovation in
drug development are cost and uncertainty. Stakeholders in all areas of
industry repeatedly tell FDA that their biggest obstacle to successful
drug development is uncertainty. FDA has taken an approach to
supporting new drug innovations by generating initiatives to drive down
development costs and reduce uncertainty in all phases of drug
development.
FDA is spearheading several initiatives to directly reduce the cost
of drug development. For example, we are making great progress in the
area of Adaptive Trial Design. Clinical trials do not always go as
planned and Adaptive Trial Design allows the drug sponsor to change a
clinical trial after patients are enrolled without compromising
researchers' ability to assess the effectiveness of the drug being
studied. This helps researchers make important changes to studies that
otherwise may be delayed or discontinued and helps bring down the costs
of clinical trials, which are often extremely expensive. We have also
co-founded the Clinical Trials Transformation Initiative with Duke
University to modernize the entire clinical trial system.
FDA is also working to reduce the scientific uncertainty in drug
development. For example, we have collaborated with the European
Medicines Agency (EMA) to found the Predictive Safety Testing
Consortium (PSTC). The PSTC has brought together scientists from 17
drug companies, who collaborate to share and validate each other's
safety methods. Such collaboration advances scientific knowledge and
helps the industry to develop safer drugs faster and less expensively.
FDA's recommendations for PDUFA V include proposals aimed at
promoting innovation through enhanced communication between FDA and
sponsors during drug development. Enhanced communication should help
sponsors better understand how to best test their products for safety
and effectiveness and ultimately bring new treatments to the U.S.
market.
One proposal will establish a new review model for the more
innovative products (New Molecular Entity New Drug Applications and
original Biologics License Applications) aimed specifically at
decreasing the number of review cycles needed for approval. This model
should provide greater transparency and improve communication by
increasing the level of interaction between FDA and sponsors during the
FDA review process. Similarly, FDA's PDUFA V recommendations also
include a proposal to improve communication with sponsors during drug
development. This proposal will establish a dedicated drug development
communication and training staff that will conduct a range of tasks
associated with enhancing communication between the review team and
sponsors.
Furthermore, FDA is committed to continuing to improve the
surveillance of products after they have reached the market. Our PDUFA
V recommendations include funds to continue implementing FDA's Sentinel
Initiative. This is FDA's evolving electronic ``active surveillance''
system, which will augment FDA's current safety monitoring program. The
new system will transform FDA's ability to track the safety of drugs,
biologics, and medical devices after they reach the market and will
help to answer key safety questions about medical products in near
real-time.
Our efforts to improve the predictability of the device review
process are described in our response to question #8 submitted by
Senator Burr.
Question 14. The possibility of first cycle approval or clearance
appears to vary by review division. What steps is FDA taking to ensure
a consistent risk-benefit approach across divisions? Please describe
the application of the FDA's new risk-benefit matrix that was recently
made operational.
Answer 14. In both CDRH and CDER, the review divisions evaluate
applications from different therapeutic areas, and each therapeutic
area has different benefit-risk considerations. For example, FDA will
accept more risk with a drug to treat a potentially fatal and
previously untreatable form of cancer than we would for a chronic but
non-serious condition such as mild eczema. However, FDA has identified
the need to establish a formal, systematic benefit-risk assessment
within disease areas.
CDER is currently developing an enhanced structured approach to
considering benefits and risks in the Agency's drug regulatory
decisionmaking. We have gathered input from senior CDER leadership and
reviewers to ensure the development of a tool that can serve as a
template for the full range of benefit-risk decisions. In addition,
CDER has piloted the use of the benefit-risk framework for
pharmaceuticals in 10 case studies across review divisions in OND. In
the PDUFA V recommendations, the Agency has committed to expanding
implementation of CDER's benefit-risk assessment framework in the drug
review process, including workshops on patient-focused drug
development. FDA will also conduct a series of public meetings with the
relevant patient advocacy communities to review the medical products
available for use in specific therapeutic areas. The therapeutic areas
to be discussed will be chosen through a public process. We will begin
execution of the plan to implement that framework by the end of the
fourth quarter of fiscal year 2013.
With respect to medical devices, CDRH recently issued, with request
for public comment, a new draft guidance \34\ describing factors to
consider in making benefit-risk determinations in device premarket
review. This draft guidance explains in detail the many factors for FDA
to consider when weighing the probable benefit of a device versus its
probable risk, and also gives examples of how the factors interrelate
and how they may affect FDA's decisions. These factors include, among
others, whether the device is a first-of-a-kind treatment or
diagnostic, whether the device provides significant improvement in
diagnosis and patient management of a serious disease, how known risks
of the device can be mitigated, reliability of the study, whether there
are multiple studies and the strength of those studies, what amount of
risk the target population will tolerate in light of the condition
being treated or diagnosed and the probable benefit of the device, and
whether there are alternate treatments or diagnostic techniques
available.

\34\ CDRH, ``Draft Guidance for Industry and Food and Drug
Administration Staff--Factors to Consider When Making Benefit-Risk
Determinations in Medical Device Premarket Review'' (Aug. 15, 2011).
available at http://www.fda.gov/MedicalDeviceRegulationandGuidance/
GuidanceDocuments/ucm267829.htm.
---------------------------------------------------------------------------
By clarifying FDA's decisionmaking process for medical devices in
this way, we hope to improve the predictability, consistency, and
transparency of the review process for applicable devices. The draft
guidance includes (also for public comment) a draft worksheet that
reviewers may use in making benefit-risk determinations; we believe
that this level of documentation will be very helpful in maintaining
the consistency of review across the different review divisions and it
will provide further assurance that an appropriate decision is reached.
The draft guidance is not in final form or in effect at this time, but
CDRH has requested that interested persons provide their comments on
the guidance by November 14, so that those comments can be considered
before we begin work on the final version.
Question 15a. In 1997, Congress passed the FDA Modernization Act,
which gave amongst other things, new authority to review and
subsequently approve drugs based on limited clinical data and that
demonstrated efficacy based on a validated surrogate endpoint.
How many oncology drug applications (NDAs, BLAs, and supplements)
approved by FDA were granted accelerated approval since 2001?
Answer 15a. Between January 1, 2001, and August 30, 2011, there
have been 39 oncology drug applications (NDAs, BLAs and supplements)
approved by FDA under Accelerated Approval.
Between January 1, 2001, to December 31, 2010 (time period
referenced in questions below), there have been 36 oncology drug
applications (NDAs, BLAs and supplements) approved by FDA under
Accelerated Approval.
Question 15b. For each year, from 2001 through 2010, how many of
these accelerated applications did FDA: (i) Successfully complete in
the first cycle?
Answer 15b(i). Between the years 2001 and 2010 (denominator of 36
oncology drug applications), 32 of these accelerated approvals were
completed within the first cycle.
Question 15b(ii) Approve on the basis of two on-going confirmatory
studies?
Answer 15b(ii). Between the years 2001 and 2010, 30 of these
applications had at least one ongoing confirmatory trial at the time of
accelerated approval. A minority of applications have more than one
post-approval clinical trial required to demonstrate clinical benefit
for the specific indication approved under Subpart H.
Question 15b(iii). Approve on the basis of a single-arm study or on
the basis of a more lenient statistical orthodoxy?
Answer 15b(iii). Between the years 2001 and 2010, 23 oncology drug
applications (NDAs, BLAs and supplements) have been granted Accelerated
Approval based on single-arm trials.
Question 16. What is the FDA doing to identify and limit
redundancies within the Agency, including high numbers of FTEs who do
not review applications, to improve its productivity and efficiency?
Answer 16. It is important to recognize that both CDER and CDRH are
responsible for a variety of complex functions that are not directly
associated with the review of new drug and medical device applications.
Examples of these functions include ensuring industry's sustained
compliance with manufacturing requirements, performing post-market drug
and device safety surveillance and risk communication, developing
guidance for the pharmaceutical, biologics, and medical device
industries, conducting post-approval inspections of domestic and
foreign facilities, and analyzing and responding to Citizen Petitions.
CDRH also is responsible for implementation of the Radiation Control
for Health and Safety Act and the Mammography Quality Standards Act. In
addition, there are essential cross-cutting activities that must be
performed by CDER and CDRH personnel to support premarket regulatory
review, including management, planning, policy, information management,
and science-related activities. These non-review functions are critical
to successful regulation of pharmaceuticals and medical devices and to
the overall health and safety of the American public.
To promote productivity and efficiency, CDER is designing a quality
systems framework to enhance regulatory review and its supporting
cross-cutting business processes, to ensure consistent, scientifically
sound, high-quality work product. CDER has also been focusing on the
``Lean'' methodology for managing work, focusing on the key principles
of maximizing value while also eliminating redundancies or other waste
in business processes. In addition, CDER recently published its Data
Standards Plan, which includes several cost-cutting initiatives, such
as transitioning from paper submissions to an electronic data
submission system.
Likewise, CDRH is actively working to enhance its efficiency and
productivity. For example, starting next month, the Office of Device
Evaluation (ODE) will pilot an internal corrective and preventive
action (CAPA) system--a database in which
office-level issues, such as inconsistency in application of policies
or failure to follow policies or SOPs, will be entered and assigned to
a staff member for followup and resolution. The CAPA system will
formalize existing continuous improvement efforts and help to ensure
that identified issues are tracked to resolution and appropriate
corrective and preventive actions are taken. Office-level management
will periodically review the information contained in the CAPA system
to ensure adequate resourcing and timely resolution of issues. CDRH is
also working to modernize the tracking system that the Center uses to
manage and track premarket submissions that are under review and to
provide review performance reports. Advanced features are being added
to the system to allow for better management reports used by review
branch chiefs for everyday work and to provide reports for past
performance to identify areas in need of improvement. This project will
modernize the premarket database systems to enable the Center to
identify, collect, search, and report on medical devices in a
consistent, reliable, and efficient manner. These efforts are vital to
support and enhance the Center's premarket, post-market, and
compliance-related activities.
Question 17a. There appears to be a lack of transparency and
timeline consistency in the development and submission of FDA's
scheduling recommendations through HHS and DEA. Unnecessary delays in
process result in delayed patient access to new medicines.
Is there a documented, formal procedure for completing the
scheduling recommendation made by CDER Controlled Substance staff and
the submission of FDA's recommendation to DEA?
Answer 17a. FDA's role in scheduling drug substances under the
Controlled Substance Act (CSA) is to perform a scientific and medical
evaluation of drugs and to provide, through the Secretary of Health and
Human Services, a recommendation to the Attorney General as to whether
a drug should be controlled. Under the CSA, the Attorney General is
required to request from the Secretary of Health and Human Services
(Secretary) an evaluation of certain medical and scientific factors for
a drug or other substance, a recommendation as to whether the substance
should be controlled or not controlled under the CSA, and, if
controlled, the appropriate level of control or ``schedule'' under the
CSA. The CSA establishes the factors and findings determinative for
control.
The CSA requires the Secretary of the Department of Health and
Human Services (HHS) to notify the Attorney General, through the Drug
Enforcement Administration (DEA), at the time an NDA is submitted for
any drug having a stimulant, depressant, or hallucinogenic effect on
the central nervous system and it appears that the drug has an abuse
potential. HHS has delegated this function to FDA. FDA's CDER, and the
Controlled Substance Staff (CSS), perform this role for the Agency. In
addition, proceedings to add, delete or change the schedule of a drug
or other substance may be initiated by petition to DEA from any
interested party such as a drug manufacturer, medical society, pharmacy
association, public interest group, State and local government, or an
individual citizen.
Throughout the drug development process, CSS evaluates preclinical,
clinical, and epidemiological data to determine whether a drug under
review requires abuse liability studies or scheduling under the CSA and
recommends additional measures, such as those related to risk
management, if needed, directed to reducing abuse, misuse and overdose.
In addition, international drug control treaties to which the United
States is a signatory may affect the regulation of new drugs with abuse
liability. CSS also contributes to this area and works with the
appropriate government agencies, including DEA, the National Institute
on Drug Abuse (NIDA), HHS, and the U.S. Department of State.
The procedure for completion of the scheduling request and
submission to DEA involves CSS analyzing the factors and findings
determinative for control and preparing the scheduling recommendation
(if appropriate); consulting with NIDA, FDA Office of Chief Counsel,
the CDER Center Director, and the FDA Commissioner; reviewing the
scheduling recommendation; and forwarding to the Assistant Secretary
for Health, who makes the HHS recommendation for scheduling that is
transmitted to DEA. This procedure is described in the FDA/CDER draft
guidance entitled, Guidance for Industry: Assessment of the Abuse
Potential of Drugs.
Question 17b. During FDA's human drug review process, when does
work related to a potential scheduling recommendation start? Are there
timeline requirements for each step? How is the Agency performance
relative to this process measured?
Answer 17b. The Agency's evaluation of the abuse potential of a
drug, whether under IND or NDA review, is subject to review timelines
established under CDER's OND for all of the review divisions relative
to CDER's Good Review Practices and PDUFA. Drug scheduling under the
Controlled Substances Act (CSA) is a separate process that is largely
carried out in parallel with the PDUFA timeline. The Agency's goal for
completing the assessment of abuse potential of a drug is the timeline
for approval of the drug within the PDUFA timeline.
Typically, FDA does not begin its medical and scientific evaluation
to support a scheduling recommendation until it receives a formal
request from DEA. FDA may also initiate such an evaluation during the
drug development process. Such an evaluation typically begins during
the investigational stages of drug development or when an application
to market a new drug is received by FDA and the Agency determines that
the substance may be a candidate for scheduling under the CSA.
Question 17c. What steps, if any, is FDA taking to improve
transparency and consistency of the Agency's work on scheduling
recommendations that are ultimately submitted to DEA?
Answer 17c. It is important to understand that NDA review and drug
scheduling are two independent review processes regulated by two
different laws. NDA review and approval is under the FD&C Act and
timelines for review are established by PDUFA, while the process for
drug scheduling is under the CSA. Even though these two processes are
independent from a regulatory perspective, FDA strives to coordinate
the CSA scheduling of a drug as closely as possible with that drug's
approval for marketing.
There are many factors influencing the time it takes for HHS to
develop a final scheduling recommendation. The steps necessary to
develop a scheduling recommendation need to be performed in a certain
order. A delay in any step of the process can adversely affect the
timeliness of scheduling relative to the NDA action date.
Some of the factors that can potentially affect the timeliness of
the drug scheduling process are:
1. Timeliness, quality and completeness of data submitted by the
drug company (Commercial Sponsor) to support drug scheduling
determination by FDA.
2. Completion of all primary reviews for the new drug product
(medical/pharmacology, clinical pharmacology, chemistry, and scientific
issues).
3. Review and clearances by multiple Federal agencies (legal/
regulatory issues).
4. New or precedent-setting medical and legal issues requiring
regulatory policy development.
In order to expedite the scheduling process and to guide Sponsors
on the type of studies needed to characterize the abuse potential of a
drug, FDA/CDER published in January 2010, draft guidance entitled,
Guidance for Industry: Assessment of the Abuse Potential of Drugs link:
http://www.fda.gov/downloads/Drugs/Guidance
ComplianceRegulatoryInformation/Guidances/UCM198650.pdf. In addition,
FDA communicates to Sponsors the importance of an early interaction and
high-quality submissions to support scheduling.
If sufficient information exists to make and support a drug
scheduling recommendation, the FDA procedure, though complex, is not
excessively long or delayed and closely parallels the PDUFA timeline.
Once the HHS recommendation is with DEA, FDA is removed from the
process and not involved in scheduling other than to respond to DEA
questions on issues that may need to be clarified.

Question 1. As we briefly discussed at the hearing, I hear from
companies on a weekly basis about their plans to move their development
efforts and manufacturing overseas to places like Europe because the
regulatory pathway that is more predictable and reasonable when it
comes to assessing safety and effectiveness. This move overseas results
in the United States quickly losing its innovation edge over the rest
of the world, not to mention the thousands of jobs being lost. What
specific actions have you taken, to encourage manufacturers to remain
in the United States? How does an increase in user fees compliment
these efforts?
Answer 1. FDA's mission includes promoting the public health and
that includes facilitating medical product innovation with respect to
drugs, biologics, and devices. Global production of FDA-regulated goods
has exploded over the past 10 years, but increased globalization has
been seen across nearly all business sectors in the United States. Both
the pharmaceutical and medical device industries are moving business
overseas, mostly because of decreased costs in manufacturing and in
conducting clinical trials. However, they are still submitting their
products to FDA so that they can have access to the U.S. market.
The key challenges facing scientific progress and innovation in
drug and device development are cost and uncertainty. Stakeholders in
all areas of these industries repeatedly tell FDA that their biggest
obstacle to successful product development is uncertainty. FDA has
taken an approach to supporting new medical product innovations by
generating initiatives to drive down development costs and reduce
uncertainty in all phases of product development. FDA is spearheading
several initiatives to directly reduce the cost of drug and device
development.
FDA is also making great progress in the area of Adaptive Trial
Design. Clinical trials do not always go as planned and Adaptive Trial
Design allows the drug sponsor to change a clinical trial after
patients are enrolled without compromising researchers' ability to
assess the effectiveness of the drug being studied. This helps
researchers make important changes to studies that otherwise may be
delayed or discontinued and helps bring down the costs of clinical
trials, which are often extremely expensive. We have also co-founded
the Clinical Trials Transformation Initiative with Duke University to
modernize the clinical trial system.
In addition, FDA is working to reduce the scientific uncertainty in
drug development. For example, FDA has collaborated with the European
Medicines Agency (EMA) to found the Predictive Safety Testing
Consortium (PSTC). The PSTC has brought together scientists from 17
drug companies who collaborate to share and test new methods that are
more reliable predictors of human safety. Such collaboration advances
scientific knowledge and helps the industry to develop safer drugs
faster and less expensively.
We are committed to continuing to improve the surveillance of
products after they have reached the market. Our PDUFA V
recommendations include funds to continue implementing FDA's Sentinel
Initiative. This is FDA's evolving electronic ``active surveillance''
system--which will augment FDA's current safety monitoring program. The
new system will transform FDA's ability to track the safety of drugs,
biologics, and medical devices after they reach the market and will
help to answer key safety questions about medical products in near
real-time.
In 2004, FDA launched its Critical Path Initiative, FDA's national
strategy to help advance pharmaceutical innovation. Our long-term
efforts are showing positive signs and FDA will continue to support the
scientific community to advance new drug development. Many of the
concepts and initiatives set in motion by FDA's Critical Path
Initiative may be beginning to show signs of benefit. For instance, as
of July 23, 2011, FDA has approved 21 novel new drugs, equaling the
total approved during all of 2010. The list of novel new drugs includes
the first drug to treat lupus in over 56 years, a completely new
treatment for chronic obstructive pulmonary disease (COPD), the first
skin cancer therapy for metastatic melanoma (skin cancer) that
demonstrates an improvement in overall patient survival, the only drug
shown to be effective against medullary thyroid cancer, a new agent
that can help diagnose Parkinson's disease, and two new and highly
effective treatments for hepatitis C. Additionally, the 2011 NME list
includes drugs intended for post-surgical use: one to decrease the
likelihood of rejection after a kidney transplant and another to
prevent deep vein thrombosis and pulmonary embolism after knee and/or
hip replacement surgery.
In the device area, most of the proposed actions under CDRH's
Innovation Initiative would foster innovation for all types of devices.
For example, the new Innovation Pathway, if adequately resourced, could
be applied to all or most devices for which a clinical study has to be
conducted. In addition, the 25 actions the Agency announced it would
take in 2011 to improve the 510(k) review process are intended to
facilitate innovation for all types of devices by improving the
predictability, consistency, and transparency of our pre-market review
program.
Periodic reauthorization of MDUFA ensures that the device review
program continues to operate on a sound financial footing, to the
benefit of patients, health professionals, and industry. In part this
is related to both existing workload and inflation that FDA experiences
in operating the program.
Question 2. With a medical device tax about to hit the industry
across the board in 2013, shouldn't the Federal Government be looking
for ways to unburden industry instead of making their burden greater by
adding more user fees on top of an already onerous medical device
excise tax?
Answer 2. FDA has no jurisdiction or policy role with respect to
the medical device excise tax.
Medical device user fees consist of congressionally authorized
private money, which is paid by medical device companies to FDA in
return for FDA's commitment to meet specific performance goals.
Congress first authorized FDA to collect user fees from device
manufacturers in 2002, with the passage of the Medical Device User Fee
and Modernization Act (MDUFMA); \35\ in 2007, MDUFMA's user fee
authorities were reauthorized by Congress for another 5-year
period.\36\
---------------------------------------------------------------------------
\35\ P.L. 107-250 (2002).
\36\ Medical Device User Fee Amendments of 2007 (MDUFA 2007),
enacted as Title II of the Food and Drug Administration Amendments Act
of 2007 (FDAAA: H.R. 3580; P.L. 110-85).
---------------------------------------------------------------------------
The authority to collect user fees is subject to two statutory
triggers: if either trigger is not satisfied for a given fiscal year,
FDA loses authority to collect user fees. The first trigger prohibits
FDA from collecting fees if direct congressional appropriations to FDA
for salaries and expenses related to devices and radiological health
fall below a certain threshold. The second trigger requires that fees
only be collected and available to defray increases in the cost of the
resources allocated for the process for the review of device
applications.
FDA has the authority to collect three types of medical device user
fees: application fees (paid each time an application is submitted),
establishment fees (paid annually by all non-exempt establishments),
and product fees (paid annually for each qualifying Class III device).
The amount of each type of user fee is determined by Congress.
Application and product fees are set as a percentage of the PMA fee
(also called the ``base fee''). The law prescribes both the base fee
amount for each fiscal year, and also the percentage of the base fee
that constitutes most other fees; the law raises the base fee annually
by a certain percentage. The amount of the establishment fee (unlike
the other user fees) is set in its own section of the medical device
user fee law.
Because medical device user fees consist solely of congressionally
authorized private money, FDA may only collect fees as authorized by
Congress (and in the amounts set forth by Congress) in the user fee
law.
The current medical device user fee law is set to expire on
September 30, 2012. As required by the 2007 user fee law, FDA is
currently engaged in the process of working with various stakeholders--
including the regulated industry, as well as consumer and patient
groups--to prepare for user fee reauthorization in 2012. As part of
that process, FDA will publish its recommendations for the
reauthorization in the Federal Register, provide a public comment
period, hold a public meeting, and then revise its recommendations upon
consideration of the public comments. FDA is required to transmit its
recommendations for reauthorization of the user fee program to Congress
no later than January 15, 2012.
Question 3. Is the current draft guidance that the FDA issued in
2007 still consistent with FDA's current policies and views of what
sponsors need to demonstrate in order for an obesity drug to obtain
approval?
Answer 3. Yes. The current draft guidance is consistent with FDA's
current policies and views for what sponsors need to demonstrate for
effectiveness of an obesity drug. The 2007 draft guidance states:
In general, a product can be considered effective for weight
management if after 1 year of treatment either of the following
occurs:
The difference in mean weight loss between active-
product and placebo-treated groups is at least 5 percent and
the difference is statistically significant.
The proportion of subjects who lose greater than or
equal to 5 percent of baseline body weight in the active-
product group is at least 35 percent, is approximately double
the proportion in the placebo-treated group, and the difference
between groups is statistically significant.
To fully evaluate an obesity drug for approval, it is important to
consider the weight-loss efficacy or benefit of a drug in the context
of the drug's potential risks or harms, thereby determining whether the
drug's benefits outweigh its risks and is therefore appropriate for
approval.
FDA is planning a scientific meeting to discuss obesity and
cardiovascular safety, and we are also planning to hold a series of
stakeholder meetings where we bring in pharmaceutical and patient
groups, FDA, and other experts to talk about how obesity drugs should
be developed. We expect these meetings to be very helpful to industry.
Question 4. I was pleased to see the President's Executive order
directing agencies to examine both their existing and new regulations
to make sure they are not unnecessarily burdensome for industry and
that they support innovation. What actions and initiatives have you
done or are you currently doing or plan to do in response to the Order.
In addition, while the Order, as I understand it, only formally extends
to actual regulations, much of the work the FDA does is by guidance or
other sub-regulatory activities which have a huge impact on industry.
What other activities beyond re-evaluating the regulations are you
doing in the spirit of the Executive order. Will you be evaluating the
actions you are taking to implement the 510(k) reform plans in the
spirit of the President's order--in particular by looking at whether
any additional burdens on industry are truly necessary and how your
actions will support innovation?
Answer 4. The President has directed Agencies to review regulations
and other procedures to see if they can withdraw or modify regulations,
or otherwise improve procedures, to reduce regulatory burden and
improve competitiveness, innovation, economic growth, and jobs, while
assuring safety. As a first step in the regulatory review, the
Secretary of HHS asked each component Agency to do an inventory of its
existing significant regulations to provide information that will
assist HHS in constructing an ongoing retrospective review process. FDA
sought comment on how the Agency could revise its existing review
framework to meet the objectives of Executive Order 13563, regarding
the development of a plan with a defined method and schedule for
identifying certain significant rules that may be obsolete,
unnecessary, unjustified, excessively burdensome, or counterproductive.
FDA focuses its retrospective review effort on regulations that have a
significant public health impact and regulations that impose a
significant burden on the Agency and/or industry. FDA has under review,
or has identified, over 40 rules as candidates for regulatory review.
FDA already estimates the effects of its regulations on industry
when we initially promulgate the regulation and has been doing so for
over 30 years. The laws and Executive orders that the Agency follows
require FDA to measure the effect of regulations on employment,
innovation, and economic growth. For example, the Unfunded Mandates
Reform Act of 1995 requires that major rules include estimated effects
on employment, competitiveness, and growth. Another example is
Executive Order 12866, which requires all Federal agencies to consider
effects on innovation, when writing regulations.
On April 27, 2011, FDA published a notice in the Federal Register,
requesting comment and supporting data on which, if any of our existing
rules are outmoded, ineffective, insufficient, or excessively
burdensome and thus may be candidates for review. This docket closed on
June 27, 2011. FDA is now reviewing the comments received and will be
using the comments to inform its future regulatory review activities.
Relating to medical devices, FDA has already identified
improvements to regulatory science as well as other initiatives--such
as its medical device innovation initiative, the 510(k) Plan of Action,
and the FDA/CMS voluntary pilot for parallel review of medical
devices--that will help it and the industries it regulates innovate and
remain competitive.
With respect to initiatives under the 510(k) action plan, those
implemented by guidance or regulation will be subject to public comment
periods. Those requiring legislation are for Congress to determine. The
rest were well-vetted through the numerous opportunities afforded
industry and the public to comment on the proposals.
We are also converting the device registration and listing process
to a paperless system, allowing for the utilization of the latest
technology in the collection of information, while maintaining an
avenue for companies for which paper applications are more convenient.
This will speed reporting and analysis of adverse events and
identification of emerging public health problems, as well as lower
costs for manufacturers.
We are also revising device pre-market approval regulations
(Special PMA Supplement Changes Being Effected) to remove duplicative
requirements and streamline and clarify regulatory requirements. And we
will be proposing to allow the use of validated symbol in device
labeling, without the need for accompanying English text, thereby
reducing the burden of labeling requirements by permitting
harmonization with labeling for international markets.
Relating to drugs, FDA has reviewed its regulations and guidance
documents to identify areas in which the Agency can reduce burden on
industry and support innovation. FDA has identified several areas where
activities are already in progress to achieve these objectives. For
example, through regulations and guidance, FDA is clarifying and
streamlining safety reporting requirements for drug manufacturers to
improve the overall quality of safety reporting, to harmonize certain
reporting requirements with international standards, and to ensure
timely reporting of safety signals with critical public health
implications. In addition, FDA is revising existing regulations and
guidance documents, as well as developing new regulations and guidance,
to facilitate the electronic filing of various types of information
that drug manufacturers are required to submit to the Agency. Our
initiatives on this front include drug registration and listing
information, manufacturing site information, drug safety reports, and
clinical study data for new applications and supplements. These changes
are expected to reduce the administrative burden on applicants and
allow for more efficient and comprehensive data review by the Agency.
FDA is committed to continuous review of its regulatory framework to
improve procedures, streamline the process for compliance with
regulatory requirements, and balance innovation strategies with our
obligation to ensure the safety and efficacy of human pharmaceuticals.
Question 5. Last month the FDA issued, ``Draft Guidance for
Industry: Dietary Supplements: New Dietary Ingredient Notifications and
Related Issues.'' As you know, this document is voluminous and takes
some time to properly evaluate and analyze. Considering the potential
impact the guidance may have on industry will you extend the comment
period to provide stakeholders with enough time to review and to submit
well thought out comments on the draft guidance?
Answer 5. Yes. FDA announced in the September 9, 2011, Federal
Register (76 FR 55927) that we are extending the comment period on the
New Dietary Ingredient guidance by 60 days. until December 2, 2011.
