What
the FDA Should Learn From the RU-486 Marathon
By Diana Zuckerman
The
Food and Drug Administration did something truly surprising late last month:
It made a cautious decision that put strong safeguards in place to protect
the health of patients using a newly approved drug.
Unfortunately,
that hasn't been the norm at the FDA lately. For years, Congress has gradually
stepped up pressure on the agency, complaining that it blocked or delayed
the sale of useful and profitable medications. In 1997, a new law directed
the FDA to speed up the approval process, at the same time weakening the agency's
resources and authority to protect consumers. Chastened, the FDA today approves
more medical products and does so more quickly than ever before--but far too
many of these drugs are approved before they have been adequately tested and
scrutinized.
Last
month, however, the FDA approved RU-486--mifepristone, the abortion pill--and
its example has turned out to be instructive. The process of approving this
controversial drug was agonizingly slow and obviously politicized, resembling
a battle between warring ideologies more than a scientific review. But the
outcome makes scientific sense and protects consumers.
In
that way it reminds me of the kind of careful review and internal battles
that once gave the FDA the reputation of a fierce watchdog--a reputation it
earned when it kept thalidomide off the U.S. market 40 years ago, saving thousands
of American babies from deformities.
Lately,
the FDA has become more of a consumer adviser than a watchdog. FDA decisions
have often saved lives; but the agency's efforts to please the companies that
make drugs and medical devices--as well as Congress--have sometimes undermined
its mission to protect consumers.
I
have watched the FDA for years: first as a university researcher, later as
an investigator for the House subcommittee that oversees the agency, and now
as the head of a think tank that focuses on health issues. I have seen firsthand
how often the FDA approves medical drugs and devices whose benefits are questionable
compared to their risks--and claims that it has fulfilled its responsibility
by pointing to the often-unintelligible warnings written in fine print on
package inserts.
The
few FDA watchdogs that are left share my concerns. For example, a report by
the General Accounting Office early this year publicly stated what FDA insiders
have admitted for years: The FDA lacks the ability to track problems caused
by medical products once they are approved. That means that drugs and devices
continue to be sold long after dangers have become obvious.
The
FDA is not supposed to make moral judgments. It is supposed to approve medications
and devices solely in terms of how well they do what they promise, and what
risks they pose to the people who take them.
By
those standards, RU-486 should have been approved long ago: It had been safely
used for years in France and other countries, and there was solid research
evidence that it was effective at ending a pregnancy. Extensive data showed
that it is at least as safe for pregnant women as the alternatives, which
are surgical abortion or pregnancy and childbirth. And yet, while the abortion
pill languished in FDA limbo, many more questionable products were quickly
approved.
The
reason was the intense ideological battle over abortion, and the fact that
many members of the Republican congressional leadership--which has power over
FDA funding and programs--are opposed to abortion. So the final FDA decision
on RU-486 was a compromise: It approves the drug, but spells out very detailed
rules for how it can be prescribed, by whom, and under what circumstances
it can be used.
Under
these rules, a woman must make three visits to the doctor or clinic. During
the first, she must be examined to determine that she is no more than 49 days
into her pregnancy; she must receive counseling and get a printed document
with information on the drug; and she must sign an agreement saying that she
understands the procedure and its potential risks. Then the doctor provides
the mifepristone pill.
Two
days later, she must return to the doctor to take the second drug in the abortion
procedure, misoprostol (a drug previously approved by the FDA for other uses).
Twelve days later, she must return to the doctor, who will confirm the end
of the pregnancy or, if there are complications, arrange for her to see a
surgeon.
Such
restrictions are extremely rare. The FDA usually backs off from telling doctors
what to do, saying it can only approve or reject medical products, not regulate
how physicians use them.
For
example, our think tank, as well as the National Women's Health Network and
other health advocates, has repeatedly asked the agency to require that clearly
worded informed consent forms be signed before patients receive long-acting
contraceptives, breast implants and several other medical products, but the
FDA has refused.
Patients
will benefit from the RU-486 rules that require both the informed consent
form and the patient information brochure be written by the FDA rather than
the manufacturer. Instead of tiny print or unintelligible jargon, these materials
clearly explain how the drug works, and describe possible side effects and
warning signs of problems to watch for.
Abortion-rights
advocates say this process will restrict the availability and affordability
of RU-486. That's true. For example, doctors who cannot find surgeons to back
them up will be unable to prescribe the abortion pill. (Although the FDA lacks
the resources to ensure that all doctors abide by the rules, doctors could
certainly be vulnerable to lawsuits by any patient harmed when they do not.)
But the process also protects women from potentially serious adverse reactions
and thus provides safeguards for patients that we have not been able to obtain
for other medical products that lack the politically supercharged atmosphere
surrounding the abortion pill.
Three
recent examples dramatically illustrate why such safeguards would benefit
patients using other products.
Rezulin
was approved by the FDA in 1997 to treat Type 2 diabetes only six months after
its manufacturer submitted it for approval. That same year, Rezulin was taken
off the market in England because it was linked to serious and sometimes fatal
liver damage. The deaths due to liver damage of at least 61 Rezulin patients
were reported before the agency finally concluded earlier this year that other
available drugs were safer and just as effective. Even then, the FDA did not
take Rezulin off the market: As is its usual practice, it requested that the
manufacturer "voluntarily" withdraw the drug, which the manufacturer did in
March.
Propulsid
was a popular heartburn medication that was approved by the FDA in 1993. After
more than 80 deaths from cardiac problems were linked to the drug in the United
States, the FDA and the manufacturer announced in March that this drug also
would be voluntarily removed from the market. Even then, the FDA allowed it
to be sold for several more months.
Saline
breast implants provide an especially dramatic comparison with the RU-486
process. Because they were first sold before the FDA was authorized to regulate
medical devices, several hundred thousand women received such implants before
the manufacturer was required to submit safety data and go through the approval
process earlier this year. Saline implants were not widely used until a few
years ago, but already more than 65,000 serious adverse reactions have been
reported to the FDA. This is an amazingly high number of complaints.
Because
of the highly publicized court settlements and multimillion-dollar public
relations efforts of implant manufacturers, few medical products have been
as controversial as breast implants. So, you might expect that the FDA would
take extra care in reviewing the safety of the newly popular saline implants.
You'd be wrong.
The
FDA advisory panel considering approval was never given information about
the 65,000 adverse reactions already reported. The FDA required no long-term
safety data and made its decision without waiting for the not-yet-published
results of long-term cancer and mortality studies conducted by the National
Cancer Institute. Meanwhile, the manufacturers' studies reported extremely
high complication rates within the first three years--affecting approximately
three out of four mastectomy patients, for example. And yet, the FDA approved
saline implants, with no restrictions on which doctors could use them under
what circumstances and no requirements that patients receive clear warnings
about risks in a consumer brochure or informed consent form.
How
could this happen? The purpose of the approval process is supposed to be to
determine whether a product is safe. The FDA that I used to respect, and that
consumers have counted on, had a dual mandate--to warn consumers of possible
risks and to keep products off the market that were not proven safe. And the
lack of proof that a product is deadly is not the same as proof that it is
safe. That's why long-term research is important for products that may have
long-term risks.
The
FDA's review of RU-486 took too long and was much too influenced by political
pressure. But the final decision showed that the FDA still knows how to think
through the risks of a medical product, and put safeguards in place to protect
patients while giving them an informed choice.
Women
choosing RU-486 will be protected from most potential risks and will understand
the choice they are making. But the rest of American consumers--like the patients
harmed by Rezulin, Propulsid and implants--had better beware.
