10 Voters on Panel Backing Pain Pills Had Industry Ties

Ten of the 32 government drug advisers who last week endorsed continued
marketing of the huge-selling pain pills Celebrex, Bextra and Vioxx have
consulted in recent years for the drugs' makers, according to disclosures in
medical journals and other public records.
If the 10 advisers had not cast their votes, the committee would have voted
12 to 8 that Bextra should be withdrawn and 14 to 8 that Vioxx should not
return to the market. The 10 advisers with company ties voted 9 to 1 to keep
Bextra on the market and 9 to 1 for Vioxx's return.
The votes of the 10 did not substantially influence the committee's decision
on Celebrex because only one committee member voted that Celebrex should be
withdrawn.
Eight of the 10 members said in interviews that their past relationships
with the drug companies had not influenced their votes. The two others did
not respond to phone or e-mail messages.
Researchers with ties to industry commonly serve on Food and Drug
Administration advisory panels, but their presence has long been a
contentious issue.
The agency has said it tries to balance expertise - often found among those
who have conducted clinical trials of the drugs in question or otherwise
studied them - with potential conflicts of interest.
Several of the panel members flagged with conflicts said most or all of the
money went not to themselves but to their universities or institutions.
The Center for Science in the Public Interest, an advocacy group in
Washington that maintains a large database of scientists' industry ties
culled from disclosures in medical journals and other public documents,
analyzed the panel members' affiliations at the request of The New York
Times.
The center has been a frequent critic of the F.D.A. and of the
pharmaceutical industry. The center's analysis may understate the industry
ties of the panel participants because some ties may not have been
previously disclosed publicly.
Dr. Sheldon Krimsky, a science policy expert at Tufts University, said such
conflicts were common on F.D.A. advisory panels. The agency often conceals
these conflicts, and studies have shown that, taken as a whole, money does
influence scientific judgments, Dr. Krimsky said.
He added, "F.D.A. has to work harder to fill panels with people without
conflicts, and if they feel they have the best committee, they at least
ought to make it transparent."
But Dan Troy, a Washington lawyer who was until last year the agency's
general counsel, said that finding knowledgeable experts without financial
conflicts was difficult. Suggesting that such conflicts skew a panel's
decisions "buys into an overly conspiratorial view of the world," Mr. Troy
said.
A spokeswoman for the F.D.A. said no one at the agency would comment on
specific panel members' industry ties.
Before each of three meetings of the advisory board last week, an agency
secretary read a statement absolving panel members of conflicts of interest
because the committee's agenda involved "issues of broad applicability and
there are no products being approved."
The secretary also said, "The Food and Drug Administration acknowledges that
there may be potential conflicts of interest, but because of the general
nature of the discussions before the committee, these potential conflicts
are mitigated."
But the committee took nine votes, three for each drug, on whether Celebrex,
Bextra or Vioxx hurt the heart, should continue to be marketed and, if so,
under what restrictions. These votes were deeply important to the three
companies - Merck, Pfizer and Novartis - that came before the committee.
Indeed, shares of Merck and Pfizer soared last Friday after the panel's
votes.
Ten members of the panel have worked in some capacity in recent years for
Merck, the maker of Vioxx; Pfizer, the maker of Celebrex and Bextra; or
Novartis, which is applying to sell Prexige, a very similar pill discussed
by the panel, according to the public disclosures.
An 11th panel member, Dr. Jack Cush, a rheumatologist at Presbyterian
Hospital in Dallas, said a disclosure that he once consulted for Pfizer was
incorrect, so he was excluded from the analysis.
Of the 30 votes cast by the 10 panel members on whether Celebrex, Bextra and
Vioxx should continue to be marketed, 28 favored the drugs. Among the 66
votes cast by the remaining 22 members of the panel, just 37 favored the
drugs.
Dr. Steven Abramson, a rheumatologist at New York University School of
Medicine who was on the panel, has consulted for Pfizer and Novartis. "The
F.D.A. is looking for people who understand the science behind these
medicines," and such an understanding often results from working with drug
makers, he said.
Dr. John Farrar, a neurologist at the University of Pennsylvania who has
received research support from Pfizer and is a panel member, agreed. "I
think F.D.A. would have a hard time finding people who are good at what they
do who never spoke to a pharmaceutical company," he said.
But Dr. Curt Furberg, a panel member and an epidemiologist at Wake Forest
University who had no ties to any of the drug companies, said he was
"uncomfortable with the Pfizer-friendly undertone" at the meeting. And he
worried that Pfizer's financial relationships with some panel members might
have played a role in setting that tone.
Joan Wainwright, a spokeswoman for Merck, said the company had had no role
in choosing any of the scientists on the panel.
Merck has made no decision on whether it will reintroduce Vioxx, Ms.
Wainwright said. "We look forward to discussing the outcomes of the meeting
with the F.D.A. and other regulatory authorities," she said.
Andy McCormick, a spokesman for Pfizer, said the company had no plans to
withdraw Bextra from the market. He also said that Pfizer had played no role
in helping to choose the panel.
Critics of the drug industry said they were not surprised that the panel's
decisions would have been different if scientists with financial ties to the
companies had recused themselves from the votes.
"My employees usually vote for me as well," said W. Mark Lanier, a lawyer in
Houston who represents people who have sued Merck after taking Vioxx and
suffering heart attacks or strokes.
Some lawyers and Wall Street analysts said last week that the panel's
decision would help to protect Merck and Pfizer from lawsuits. But juries
will be more skeptical of the decision after they learn about the
composition of the panel, Mr. Lanier said.
Christopher A. Seeger, a lawyer in New York with many Vioxx clients, said
the fact that scientists had not recused themselves simply highlighted the
close ties between the drug industry and academic researchers. He said
researchers were afraid to say anything negative about new drugs because
doing so might jeopardize their chances of participating in clinical trials
and publishing papers.
Several panel members said the important split on the committee was not so
much between those with industry ties and those who did not have those ties
but between experts who treat arthritis patients and those who do not.
Dr. Cush was angry that the voices of the panel's rheumatologists were
nearly drowned out by statisticians and others who do not have to cope with
anguished patients every day.
Dr. Furberg said clinicians often wanted access to therapies without
understanding the devastating public health consequences of their
prescribing decisions. Celebrex, Bextra and Vioxx have never been proved in
clinical trials to cure pain any better than ibuprofen or more than a dozen
other, older pain pills.
"Fifty patients a day probably die from those drugs, and who is speaking for
them?" Dr. Furberg said.
Dr. Alastair Wood, an associate dean at Vanderbilt University and the
panel's chairman, said he was disappointed that the F.D.A. failed to
disclose the financial conflicts of the panel's participants before each
day's meeting.
"I'm a great believer in letting it all hang out," he said.
Still, Dr. Wood said that even with its conflicts the panel was a tough
critic of the drugs. Many of the panel members who were among the narrow
majorities approving continued marketing of Bextra and Vioxx did so only
with the stipulation that severe restrictions be imposed on their uses, he
noted.
He said he expected that the uses of the drugs would be confined to very
limited patient populations.
