MODERN-DAY
SNAKE OIL?
THE VIOXX SCANDAL AND THE CRISIS OF DRUG
SAFETY
By Philip
Mattera
Over a period
of five years, pharmaceutical giant Merck &
Co. spent about $500 million promoting its
arthritis drug Vioxx to consumers through a
marketing campaign spearheaded by TV
commercials featuring Olympic skater Dorothy
Hamill. It recently became clear that the ad
campaign and Merck were skating on thin ice.
On September
30 Merck announced that it was withdrawing
Vioxx from the market because of evidence
that the drug created an elevated risk of
heart attack and stroke. Although the
company acted voluntarily, it has
experienced a firestorm of criticism over
mounting evidence that it knew of the risks
for years and kept on selling the drug,
which reached $2.5 billion in sales last
year. Prior to the recall, some 20 million
people took Vioxx, and it is now estimated
that tens of thousands of them may have died
of side effects known to the company. Merck
could be responsible for more deaths than
any other company in business history.
Apart from
questions of gross negligence, the Vioxx
scandal also raises issues about the
efficacy of the system of federal regulation
of new drugs and the out-of-control practice
of marketing risky pharmaceuticals directly
to consumers. It also is a poignant reminder
of the importance of product liability
litigation—Merck is facing billions of
dollars in potential liability—despite the
repeated calls by business apologists for
tort “reform.”
FROM SNAKE OIL TO ETHICAL DRUGS
Vioxx is far
from the first case of a drug company
accused of sidestepping safety
considerations in promoting its wares. The
problem dates back more than 100 years.
The original
drug industry in the United States was
something less than respectable. During much
of the 19th Century, the business
was dominated by so-called patent medicine
producers, who sold a variety of extracts,
tinctures, syrups and other concoctions that
would supposedly cure dozens of different
ailments. Some of the nostrums were merely
ineffective solutions made up mainly of
water; others contained addictive substances
such as opium or might be poisonous.
This “snake
oil” system came under increasing criticism
from the medical establishment, which was as
much concerned about the fact that users of
patent medicines did not consult physicians
as it was about the dangers of those
preparations. Around the 1880s, physicians
as well as pharmacists and others began
establishing “ethical” drug houses, meaning
that they revealed the contents of their
products and sold to doctors rather than
consumers.
The
pharmaceutical industry successfully
replaced quack medicines with generally more
reliable products, but fraudulent claims and
dangerous side effects were not entirely a
thing of the past. Although Congress had
passed the Pure Food and Drug Act of 1906,
federal regulation of the industry was weak.
That changed in the 1930s in the wake of a
scandal involving S.E. Massengill Company of
Tennessee, which introduced a liquid
antibiotic called Elixir of Sulfanilamide.
The product was not tested, and it turned
out to have a devastating effect on the
kidney. More than 100 users suffered a slow,
agonizing death before the cause was
discovered.
The outcry
over the Elixir case helped bring about the
passage of the Food, Drug and Cosmetic Act
of 1938, which established much stricter
safety standards and rules for testing. Such
regulations were tightened by additional
legislation enacted in 1962 after the
tragedy involving horrific birth defects in
the children of women (mostly outside the
United States) who took the sedative
Thalidomide for morning sickness during
pregnancy.
While the
pharmaceutical business enjoyed a resurgence
starting in the 1970s thanks to the
introduction of blockbuster products such as
the ulcer medicine Tagamet, the industry was
also tainted by a series of safety
controversies. These involved products such
DES (diethylstilbestrol), which was marketed
by several companies to prevent
miscarriages, despite evidence that it
caused cancer in animals. By the 1970s,
daughters of women who had used DES were
reporting complications involving vaginal
and cervical cancer. Another example was
Oraflex, an arthritis drug introduced with
great fanfare by Eli Lilly in 1982. The drug
was subsequently linked to internal bleeding
and kidney and liver problems. In 1985 Lilly
pleaded guilty to charges that it had failed
to inform the FDA about serious adverse
reactions to the drug, including several
deaths.
Despite cases
such as these, the FDA found itself under
attack in the 1990s for being too stringent
in its approval process. Soon after becoming
Speaker of the House, Newt Gingrich called
the FDA commissioner at the time, David
Kessler, a “thug and a bully.” The victims
of this supposed bullying was a drug
industry that was already taking in more
than $50 billion a year in the United
States.
Congress saw
to it that the FDA accelerated its new drug
approval process, but the change apparently
backfired. In the late 1990s the agency had
to remove a record number of products from
the market because of harmful side effects
that became known only after the drugs were
already in distribution. In some cases the
FDA had to be pressured to act. In 2000 the
FDA recalled the Warner-Lambert diabetes
drug Rezulin only after public interest
groups and investigative reporters had
highlighted problems such as more than 90
cases of liver failure linked to the
medication.
In 2001 Bayer
withdrew its cholesterol drug Baycol from
distribution after reports that at least
several dozen users had developed a
debilitating muscle-weakening condition. The
company was subsequently hit with some
10,000 lawsuits.
THE “MIRACLE COMPANY” FALLS FROM GRACE
Merck was not
typically associated with drug safety
problems. For decades it had a reputation
for both outstanding research work and
superior management. A 1987 Business Week
profile of Merck was headlined “The Miracle
Company.”
During the
1990s, however, the output of Merck’s labs
was somewhat less miraculous, and the flow
of new blockbuster products slowed. The
company was also approaching the end of
patent protection on five of its top
sellers. Merck, which had resisted the
pressure to merge with a competitor,
consequently had a lot riding on the success
of Vioxx after its introduction in 1999. The
challenge was heightened by the fact that
Vioxx had to compete with another arthritis
drug called Celebrex that entered the market
around the same time. On the cover of its
1999 annual report, Merck bragged that Vioxx
was the “biggest, fastest, and best launch
ever.”
It was thus no
surprise that when questions began to be
raised about the cardiac side effects of
Vioxx, Merck did its best to downplay the
risks. For example, when research completed
in 2000 showed that users of Vioxx had a
higher rate of serious cardiovascular events
than users of naproxen (sold as Aleve),
Merck officials argued that this did not
necessarily mean that Vioxx increased the
risk; instead, they suggested that naproxen
reduced the risk. That position became
untenable when new research comparing Vioxx
to a placebo was completed in 2004 and
showed an elevated cardiovascular risk
associated with the Merck product.
When Merck
pulled Vioxx off the market in September,
CEO Raymond Gilmartin declared that the
company was “putting patient safety first”
and insisted that it had only recently
received conclusive evidence of the drug’s
serious risks. Yet internal company e-mail
messages and marketing material that have
since been disclosed suggest that as early
as 1996 Merck was quite aware of the hazards
of Vioxx. Rather than considering withdrawal
of the product, the emphasis in many of the
documents was on finding ways to deflect the
criticism and discredit those making it. One
internal document obtained by the Wall
Street Journal presented company
officials with one word of advice in dealing
with questions about the safety of Vioxx:
“DODGE!”
While Merck is
under assault from many quarters—the company
has disclosed that it is being investigated
both by federal prosecutors and the
SEC—pointed questions are also being
directed at the FDA. Although reports of
adverse reactions to approved drugs have
been on the rise, FDA enforcement activities
have declined since the beginning of the
Bush Administration. On November 18, Dr.
David Graham, a maverick career drug safety
official at the FDA, painted a calamitous
picture in testimony before a Senate
committee. He depicted the agency as
“incapable of protecting America against
another Vioxx” and he called for stricter
curbs on five other specific drugs that are
already on the market.
When the FDA
accelerated its approval process in the
1990s, the tradeoff was supposed to be more
stringent oversight of drugs once they were
on the market. It now appears that the
public was double-crossed. The big
pharmaceutical firms get their products into
distribution sooner, but the FDA is no more
aggressive in monitoring their adverse
effects. At the same time, drug houses are
allowed to promote their wares directly to
consumers, which promotes overuse and means
that dangerous drugs like Vioxx end up
spreading their harmful effects on much
larger populations. Excessive marketing,
insufficient corporate concern for safety,
and feckless regulation—perhaps we haven’t
come all that far from the “anything goes”
days of snake oil medicine.
