New Website Speaks Out
on
FDA's Unhealthy Policies
The cost in terms of human suffering and economic
loss that stems from the FDA's failed policies is too high. That's why
Daniel Klein, Ph.D. and Alex Tabarrok, Ph.D. decided to pool their knowledge
and develop a website (www.FDAReview.org)
that provides a meticulous dissection of the FDA's multiple troubles.
by Angela Pirisi
After pouring over academic and medical literature on FDA policy for
years, Drs. Klein and Tabarrok could reach only one conclusion: "The FDA
greatly increases the costs of drug development and the time it takes
to bring a drug to market. The net effect is loss of health and life."
The website, they hope, will help to present the facts, inconsistencies,
injustices, and help advance the public debate on FDA reform. It traces
federal drug regulation back a century, details the steps involved in
drug development and approval, presents an evaluation of the costs and
benefits of FDA policy. Klein and Tabarrok also size up the major plans
for FDA reform, and offer their own solutions for getting out of the current
quagmire of misguided policies bred by what they deem excessive caution.
The thrust of Klein and Tabarrok's argument is that while it may seem
like a good idea to have empowered the FDA to make sure only safe and
effective drugs come onto the market, it doesn't work well in practice.
Fearful of scandal and criticism, the FDA has focused so hard on keeping
some "bad" drugs from making it to the marketplace that, in so doing,
it has also prevented or delayed many more good drugs from reaching Americans.
It seems to be a calculated risk for the FDA, since potentially good drugs
that never see the light of day receive a lot less media attention than
harmful drugs that are exposed, suggest Klein and Tabarrok.
"The FDA was established in a fitful series of ill-considered responses
to highly-publicized tragic events, particularly the sulfa tragedy in
1937 and the thalidomide disaster. Let's accept, for the sake of argument,
that the FDA has helped to avoid some tragedies of this sort," says Klein.
"Nevertheless, you still have to do the grisly math. How many lives have
been lost because the FDA delayed a life-saving drug? How many lives have
been lost because FDA regulation made it unprofitable to develop a new
life-saving drug? How many lives have been lost because the FDA refused
to allow advertisers to make scientifically supportable health claims?
When you do the grisly math it isn't even a close call. The FDA is a major
health catastrophe."
What the FDA considers choosing the lesser of two evils may not be unlike
throwing the baby out with the bathwater. Consider, say Klein and Tabarrok,
the headlines that pop up when drugs that have FDA's stamp of approval
do grievous harm to some people. In 1994, they cite, an estimated 106,000
or more people died from adverse reactions to "safe" FDA-approved drugs.
On the flip side, pulling drugs off the market for doing harm to some
people may be doing a disservice to many others, who can no longer benefit
from that drug because the FDA paints all patients with the same brush.
"In fact," says Tabarrok, "the FDA is probably too quick to withdraw products
from the market. Many drugs are safe for most people but seriously dangerous
for a few, and it can be very difficult to discover this in clinical trials.
Suppose that a drug is deadly to one out of every 5,000 patients. It would
be very difficult to discover this statistically even in a large and expensive
clinical trial of say 10,000 patients. These sorts of problems can only
be discovered once the drug is approved and prescribed to hundreds of
thousands of people. Unfortunately, there is sometimes no substitute for
experience. Life's like that." Using the example of chemotherapy and warfarin
(blood thinner that's also commonly used as rat poison), Klein and Tabarrok
suggest that all drugs are equivocally good and bad, depending on who's
using them. So, subjecting drugs to a "guilty until proven innocent" trial
basis may be arbitrary if, in the end, only widespread use in real-life
patients offers true proof of a drug's efficacy and safety.
The problem-FDA as permission grantor
Part of the trouble, complains Klein, is that, "People conflate FDA permission
with medical validation or certification. By mixing legal matters such
as government permission with real medical matters, the present regime
might actually be confusing people. If drugs weren't banned till permitted,
but rather permitted till banned, the situation would be less complicated.
Then the FDA would be merely a drug certifier, not a permission grantor.
You'd be free to try whatever therapies you chose. So, contrary to what
people might suppose, in fact, discussion and negotiation of your medical
options might proceed in a more informed-not less informed-way." Says
Tabarrok, "The simple fact is that the FDA restricts the freedom of patients
and their doctors. Individuals certainly have better incentives to look
after their own health than does the FDA. The real question then comes
down to information-does the FDA possess a big information advantage that
enables it to make better choices for individuals than individuals would
make for themselves? This is why we spend time at FDAReview.org explaining
and evaluating the rich constellation of voluntary institutions and practices
that help patients to make good choices even when their information is
imperfect. Patients don't choose alone but with the help of agents and
advisors, such as doctors, hospitals and pharmacists. [These individuals
and entities] have access to information in the scientific literature,
drug evaluation service(s)-such as the USP Pharmacopoeia-information from
ECRI and UL, which evaluate and test medical devices, and so forth. Putting
all this together, we see little grounds for believing that the FDA offers
a valued service." Besides, Tabarrok adds that the FDA may pride itself
on having the best and most rigorous standards in the world for drug approval,
but patients in Europe don't hold their breath about U.S. FDA drug approval
before using a new drug their doctor prescribes.

How vigorous is the FDA approval process anyway, and how relevant is
it when there are so many off-label uses for FDA-approved drugs? The fact
is that the drugs [it] approves based on small study populations, in reality,
are prescribed to a much bigger, non-homogenized group for reasons other
than those that were tested. That goes to show how much stock both U.S.
doctors and patients put into the "FDA-approved" stamp. "Actually, when
people are sick, what they really put stock in is the approval of their
doctor, their hospital, and so on. Most cancer and AIDS patients, for
example, are prescribed drugs for an off-label use-that is, a use for
which the drug does not have FDA efficacy certification," explains Tabarrok.
"And any doctor who limited himself to FDA-approved prescriptions would
be giving his patients inferior service and could easily be sued for negligence."
The long, twisted road to market
As it is, people may suffer long into a debilitated state, or even death,
before a viable drug therapy for their disease or condition ever reaches
their pharmacy. One of the leading problems symptomatic of the FDA's unhealthy
policies is "drug lag." An example of this is the recent approval (May
2001) for enhancing infant formula with two vital fatty acids, AA and
DHA, which can improve the brain and eyes of young children. While it's
a welcome decision for American parents and pediatricians, Klein and Tabarrok
point out that the FDA falls far behind other countries, such as Britain,
Japan, Israel, Belgium, the Netherlands and more than 50 other countries,
where enriched infant formula has been available, in some cases, even
more than five years. Moreover, back in 1994, the World Health Organization
recommended that all infant nutrition products be enhanced with AA and
DHA in the same quantities and proportions as occur naturally in breast
milk.
But the excruciatingly long delay that precedes new drugs being okayed
isn't the worst of it, since drug lag also reduces the total number of
new drugs created, otherwise known as "drug loss." The FDA has long rested
easy knowing that it is painfully difficult to measure the amount of drug
loss or its health consequences, and that the public is none the wiser
about treatments that could have been but never will be. In rare cases
where the public has been aware, however, there have been strong patient
outcries to have their medicine back. On the web site, Klein and Tabarrok
cite the example of Latronex, a short-lived drug indicated for irritable
bowel syndrome, which was removed from the market after 70 users developed
a serious side effect, and three deaths were possibly linked to the drug.
Yet they remark that the hundreds of people who found relief in Latronex
without suffering adverse reactions were outraged when the FDA snatched
away this new therapy from everyone. "The example of Latronex indicates
how the FDA's 'one size' policy can harm many patients," says Tabarrok.
"The FDA could better serve all patients if, instead of making don't-take-it
choices on behalf of patients whom it can't know or understand, it collected
and disseminated information that helped doctors and their patients make
informed choices in the context of the patients' lives. That way the FDA
would respect the uniqueness of each patient's conditions. Treating consumers
with respect is a better policy than paternalism, both medically and ethically."
FDA needs a new prescription
To date, the FDA has made some efforts to address the issues at hand,
but Klein and Tabarrok say these are modest at best. For example, the
FDA has been responding to some pressure to speed up drug approval with
their "Fast Track" program, which is meant to shorten the time, and thereby
reduce the cost of getting drugs to market. But how much of a difference
will it actually make? Probably not much, says Tabarrok, who describes
the program as one step forward, two steps back. "The FDA has hired more
reviewers in recent years thanks to the User Fee Act of 1992, which has
reduced the time it takes the FDA to review applications," he explains.
"But at the same time, the FDA has asked for more and longer clinical
trials. In 1980, the typical drug underwent 30 clinical trials involving
about 1500 patients, but in more recent years the typical drug has had
to undergo more than 60 clinical trials involving nearly 5000 patients."
The result? The total time from discovery to approval is still around
12 to 15 years, and the average cost of getting a new drug to market is
now 800 million dollars with no sign of dropping. "The FDA responds to
critiques by pointing to the decrease in review times under Fast Track,"
says Tabarrok, "but astute observers will keep their eye on the total
costs and time of getting a drug to market."
"The problem can't really be solved by a new wrinkle or FDA goodwill,"
he adds. "What's needed is substantial reform that alters the structure
of power. Klein and Tabarrok have some suggestions of their own.
Give knowledge and power to the consumer
Why not redefine the FDA as a trusted advisor and evaluator of medical
drugs and devices, whose goal would be to inform patients "rather than
to dictate and constrain their choices"? Historically, the FDA has resisted
the free flow of medical information down to the consumer, a perfect example
of the tight-lipped policy today that perpetuates the tradition of prescription
labels that provide almost no patient information. "Even today, consumers
typically don't receive a copy of the product label with their prescription,"
says Tabarrok. "If they're lucky, their pharmacist may give them a computer-generated
synopsis of warnings and contraindications. Consumers can and should ask
for product labels with their prescriptions. The FDA should also pay more
attention to designing labels that can be easily read and understood."
Another strategy to empower consumers would be for the FDA to allow split
labelling on all drugs and medical devices, so that drug manufacturers
could list FDA-approved claims down one column, and those that have "not
been evaluated by the Food and Drug Administration" down another. The
split-label approach would mean that all of a drug's common uses are described
on the label, including off-label uses.
Make the FDA a certifier of drug certifier
Establishing a group of nongovernmental drug-certifying bodies would
encourage healthy competition for contracts from pharmaceutical companies
developing new drugs. Such a free market proposition would create incentive
to be thorough, accurate, expedient and cost-effective. And, unlike the
FDA, the certifying bodies would be liable to litigation for negligence.
While hired drug-certifying bodies would oversee the initial review and
evaluation of proposed new drugs, the FDA would ultimately decide whether
to certify a drug or not. But it would be expected to do so within a 90-day
review period, and failure to respond in this timely manner would constitute
automatic approval. Similarly, the FDA would have to provide a written
explanation of why it has rejected an application, and drug companies
would be able to appeal the FDA's decision through an independent committee
of experts.
Draw on other countries
One of Klein and Tabarrok's primary suggestions for FDA reform is establishing
drug-approval reciprocity with countries that have a proven record of
approving safe drugs, such as most western European countries, Canada,
Japan and Australia. This would help the U.S. to speed up the drug approval
process, eliminate duplication and wasted resources, and focus, in a more
expedient manner, on the review and investigation of new drug applications.
Also, international reciprocity would eliminate the FDA's monopoly on
drug approval by allowing U.S. drug companies to seek approval from drug
authorities in partner countries.
Refocus on drug safety only
Given the many off-label uses of FDA-approved drugs, which speaks to
efficacy evaluation being performed by other institutions, why not focus
strictly on proof of safety? "That would greatly expand the range of drugs
developed (in particular for rare diseases), increase the speed with which
they get to market, and significantly reduce costs and drug prices," suggest
Klein and Tabarrok.
Make FDA approval optional
Klein and Tabarrok believe that when the FDA grants permission to allow
drugs into the marketplace, it's not "approval" so much as the lifting
of a ban, since anyone who uses, prescribes, produces or sells a drug
prior to FDA approval is prosecuted under the full weight of federal law
backing FDA policy. But why not make FDA drug testing and certification
optional? Klein and Tabarrok suggest having in its place voluntary practices,
individuals and institutions, such as reputation, knowers and middlemen,
which assure quality and safety because it is profitable to satisfy the
consumer and live up to one's promises. That would make the FDA only one
of several certifying bodies specializing in testing drugs and medical
devices.
