REGULATION: The FDA at 100
By Henry I. Miller
As the FDA heads into a second century, its
fundamental flaws are more apparent than ever. Why the FDA can’t (or
won’t) reform itself. By Henry I. Miller.
The FDA’s celebration of its centenary this
year is far from triumphal. Drug research and development—and their
government regulator, the FDA—are ailing. The costs of drug
development have skyrocketed, with direct and indirect expenses to bring an
average drug to market now exceeding $800 million. Other trends are ominous
as well:
Longer clinical testing extends the time it
takes to bring new prescription drugs to market; new medicines that gained
FDA approval during 2002–4 required an average of 8.5 years to move
through the clinical trials and approval phases, as compared to 7.2 years
in 1999–2001.
Only 58 new drugs in 2002–4 received
marketing approval, a 47 percent decline from the peak of 110 during the
1996–98 period.
The number of applications for marketing
approval to the FDA from industry has been decreasing steadily since 1995.
Fewer than one in three drugs that are
approved for marketing ever recoup their development costs.
FDA reviewers and managers are conditioned to be
risk-averse. As former FDA commissioner Alexander Schmidt observed:
“In all our FDA history, we are unable to find a single instance
where a congressional committee investigated the failure of FDA to approve
a new drug. But the times when hearings have been held to criticize our
approval of a new drug have been so frequent that we have not been able to
count them. The message to FDA staff could not be clearer.”
Thus regulators, having become phobic about risks,
make decisions defensively, at the cost of denying patients new drugs that
can cure diseases and save lives. The regulators tend to delay or reject
products of all sorts, from fat substitutes to vaccines to painkillers.
That’s bad for public health and for consumers’ freedom to
choose.
A phrase that one commonly hears among FDA-watchers
is that the agency lacks “adult supervision.” During the past
six years, a confirmed commissioner has held office for less than 20
months, “a clear signal that FDA doesn’t matter much to the
people who are running the country, . . . [which] can’t help but
affect morale,” according to Donald Kennedy, former FDA commissioner
and former president of Stanford University.

Poor management at the FDA goes back almost two
decades. Agency heads David Kessler and Jane Henney, who presided over the
deteriorating morale and the lack of focus on public health, politicized
the agency to the greatest extent in its history. And about current acting
FDA commissioner Andrew von Eschenbach, one senior agency official offered
this assessment: “He is smart and pays attention . . . [but] I have
the strong impression that no one is running FDA, and that even if anyone
were, no one is running [the Department of Health and Human Services] and
so nothing remotely controversial, which seems to include any decision on
anything that hasn’t been decided before, can get done.”
Far too much has slipped through the bureaucratic
cracks for anyone to be sanguine about the agency’s ability to
accomplish reform from within. For example, although Dr. Janet Woodcock,
the FDA’s deputy commissioner for operations, is intelligent,
collegial, and forward thinking in many ways, she has been unable to
address the agency’s deficiencies for more than a decade. Appointed
in 1994 to head the FDA’s Center for Drug Evaluation and Research,
which oversees industry’s testing of new drug candidates, sanctions
their marketing, and monitors them after they are approved, Dr. Woodcock
was promoted several years ago to deputy director of operations for the
entire FDA.
Deputy Commissioner for Medical and Scientific
Affairs Scott Gottlieb is the FDA’s public face and a vocal champion
of greater agency flexibility. Still, he overestimates the effect that
changes in science have on the agency’s culture. “If we could
develop better science, there could potentially be smaller trials”
and lower costs, according to Dr. Gottlieb. True enough. But these kinds of
innovations merely tinker at the margins of a fundamentally flawed system
in which line reviewers are too risk-averse to embrace reforms that might
expose them to media or congressional criticism.
Another of Dr. Gottlieb’s
remedies—ostensibly to speed approvals—is extending “user
fees” (which drug companies pay to the FDA for the review of
submissions) to generic drugs. But user fees are merely a euphemism for a
discriminatory tax on a single corporate sector. Such fees have been in
place for brand-name drugs for almost 15 years—and all we have to
show for them are the negative trends described above.
Dr. Gottlieb’s public statements must be
weighed against recent FDA actions. Even as he criticized the overuse of
“risk minimization action plans,” which the FDA applies to
drugs after they are marketed, the agency imposed a particularly harsh and
inappropriate plan as a condition for reintroducing to the market the
multiple sclerosis drug Tysabri.
What we need is not promises of better science or new
taxes on drug development. Ultimately, only inspired senior management
willing to reform the agency’s deeply risk-averse culture—and
to defend its actions before congressional and other critics—can
produce the impartial, data-driven performance that will benefit patients.

FDA-watchers joke that the agency lacks “adult supervision”—during
the past six years, a confirmed commissioner has held office for less than 20 months.

This will not be easy because the contract between
society and FDA regulators has been violated. Lifetime tenure for civil
servants—which itself exacts costs—is supposed to free
regulators to consider only the public interest as they render decisions.
Instead, it has given us the worst of both worlds. On the one hand, it has
become virtually impossible to remove incompetent or adversarial federal
civil servants; on the other, we are forced to live with decision making by
federal officials who are frequently influenced by perceived risks to their
careers.
During the FDA’s second century, the culture of
excessive risk aversion at the agency must be changed, but, sadly, it may
take a public health crisis—a pandemic or a massive bioterror
attack—to accomplish what several generations of FDA leadership have
been unable to do.
