Sponsored Clinical Trials Studied

The drug companies that pay for major testing of
most new medicines give the participating university researchers little or
no say in how the studies are designed and how the findings are handled, a
survey found.
The survey of 108 medical schools, published in Thursday's New England
Journal of Medicine, is the latest sign of growing concern about conflicts
of interest between those doing scientific research and the pharmaceutical
companies sponsoring it.
"What the institutions have told us is they feel almost powerless in
these contracts," said Dr. Kevin Schulman, a Duke University Medical Center
professor who led the survey.
While federal agencies sponsor much early research, large-scale studies
of drugs' safety and effectiveness are usually paid for by the
manufacturers. Typically, the companies hire medical school faculty members
to carry out the studies.
But some scientists worry their lack of control could threaten the
integrity of research and the safety of the volunteers participating. Among
other things, pharmaceutical companies have sponsored research that found a
drug didn't work or was dangerous, then suppressed the results.
Concerned about the problem, the International Committee of Medical
Journal Editors in 2001 published guidelines for research contracts between
medical schools and the pharmaceutical industry.
Last winter, researchers at Duke University Medical Center and Duke's law
school interviewed officials at U.S. medical schools and reviewed some of
their research contracts to determine how many complied with the new
guidelines. Only a minority did.
Schulman said researchers have less and less control over patient trials
as more and more studies include dozens of medical centers, rather than just
one, a strategy meant to bring results faster.
Among the study's findings:
Researchers rarely were allowed a say in the design of the clinical
trials, with only 10 percent of contracts covering how data is collected and
monitored and only 5 percent covering how data is analyzed and interpreted.
Less than 1 percent of contracts guaranteed that results would be
published and that an independent committee would have control over that.
But 40 percent of contracts addressed editorial control of manuscripts.
Only 1 percent of contracts required an independent board to monitor
patient safety. Such boards can stop a study early if the treatment is found
to be harming participants.
"It is very worrying," said Mary Ann Baily, associate for ethics and
health policy at the Hastings Center, a Garrison, N.Y., think tank. "The
future of research and patient welfare does depend on how we approach this."
Financial ties between academic researchers and industry sponsors already
are under scrutiny for apparent conflicts of interest, as when researchers
receive stock in a company testing an experimental drug.
Over the summer, the Pharmaceutical Research and Manufacturers of America
established voluntary guidelines for clinical research, but they are
"basically toothless," said Dr. Jeffrey M. Drazen, editor of the New England
Journal.
"The system would be better served if there were universally accepted
contractual language," he wrote in an editorial.
PhRMA spokesman Jeff Trewhitt said its member companies three weeks ago
started implementing new principles for operating and reporting on clinical
trials that "reaffirm our commitment to the safety of research participants
and a timely communication of research results."
Trewhitt said those principles cover at least some of the concerns raised
in the study and recommend paying researchers in cash, not company stock.
In another opinion piece, doctors wrote that such protections are
critical because future medical research will depend even more closely on
partnerships between universities and industry; they suggested creating a
national panel to deal with conflict-of-interest issues.
A third opinion piece by doctors and an industry consultant said
universities must set firm policies protecting their researchers from
financial influences.
