The Food and Drug Administration on February 16-18, 2005, held an advisory committee meeting to discuss the cardiovascular risk posed by painkillers known as "Cox-2 inhibitors," which include Celebrex, Bextra and Vioxx. The former two drugs are manufactured by Pfizer. The latter is manufactured by Merck. Novartis also has a Cox-2 inhibitor in its pipeline.
At the end of the hearing, the FDA advisory panel voted to keep all three on the market, though with heightened warnings about the dangers posed by this class of drugs.
Almost One-Third Had Conflicts of Interest
The CSPI research uncovered affiliations between 10 of the scientists that served on the committee and the three manufacturers of Cox-2 inhibitors. This would appear to be a direct violation of the
Federal Advisory Committee Act, which prohibits scientists with direct conflicts of interest from serving on panels offering advice to federal regulatory agencies.
Another 17 scientists had other ties to drug manufacturers, though not the three with products under consideration at the meeting, CSPI reports.
Committee Would Have Voted Against Bextra, Vioxx
According to a New York Times analysis of the votes, the advisory committee would have voted against Bextra and Vioxx staying on the market had scientists with conflicts of interest been excluded from the vote.
Here is the CSPI analysis of the FDA Advisory Panel:
CSPI found ten (10) physician/researchers with direct ties to Pfizer, Merck or Novartis (including G.D. Searle and Pharmacia, which are now part of Pfizer):

17 Others Had Ties to Pharma
In addition, CSPI found seventeen (17) physician/researchers who received research support or had other financial ties to pharmaceutical firms (but not direct ties to manufacturers of Cox-2 inhibitors).
In three cases, the ties were to Merck or Pfizer but were deemed too old to be relevant, according to CSPI.
