Telling the Truth: What Drug Companies Dont Want You to Know by Thomas Bodenheimer & Ronald Collins
Thomas Bodenheimer, M.D., is a clinical professor, Department of Family & Community
Medicine, at the University of California, San Francisco. Ronald Collins directs the Integrity in
Science project at the Center for Science in the Public Interest, a non-profit health advocacy
group in Washington, D.C.
This week the Times reported on a serious medical problem. The article by Duff
Wilson and David Heath (The Blood-Cancer Experiment) claims that patients
involved in a Protocol 126 experiment were given experimental cancer drugs
and died unnecessarily. Moreover, research scientists at the Hutchinson Cancer
Research Center, where the drug trials were carried out, allegedly had a personal
financial interest in giving patients those drugs. If true, the Wilson-Heath article
raises important professional, ethical, legal, and policy issues that must be
addressed.
As described, the Hutchinson incident is not unprecedented. For example, in
1999 Jesse Gelsinger, a healthy 18-year-old, died of an experimental drug at the
University of Pennsylvania. The principal research scientist had positioned himself
to profit if the toxic drug had worked. The Gelsinger family was not fully aware of
that conflict of interest and had not been adequately told of all the drugs dangers.
On a related front, last November the Los Angeles Times reported that a Loma
Linda University experiment used humans to test the effects of pills laced with an
industrial pollutant. Among other things, what those involved in the experiment,
funded in part by Lockheed Martin, did not know was that when they voluntarily
agreed to be guinea pigs Lockheed was being sued over the safety of the very
product being tested.
In all of this, one key problem is that too often too little is divulged. Researchers
do not regularly divulge their financial ties to drug companies when asking
patients to enroll in drug trials. Similarly, drug companies do not routinely
divulge everything the public and physicians need to know about company-funded
drug research.
Financial conflict of interest in clinical drug trials is a significant problem in the
United States. It affects millions of people those who are subjects in drug trials
and those who use the drugs once they enter the market.
Predictably, company-funded research tends to favor company products. For
example, a 1998 report in the New England Journal of Medicine revealed that
96% of medical journal authors whose research was favorable to certain cardiac
drugs had financial ties to the drugs manufacturers. By contrast, only 37% of
authors of studies critical of those drugs had such financial ties. And according to
a 1996 study published in the Annals of Internal Medicine, an amazing 98% of
company-sponsored drug studies published between 1980 and 1989 in peer-reviewed journals or in symposia proceedings favored the funding companys
drug.
Equally troubling, drug companies frequently own and control the data collected
in drug trials. Even the university scientists conducting the trial may not be given
all the data they need. Companies sometimes publish data favorable to their
product while suppressing unfavorable data. Take the case of Dr. James O. Kahn,
who not long ago published a study in the Journal of the American Medical
Association. His study concluded that a vaccine for AIDS simply didnt help
patients. The corporate funder of that study refused to give Dr. Kahn (the principal
investigator) all the data. It then tried to block publication of the research. When
the study was finally published, the corporation initiated a $7 million-10 million
legal action against Dr. Kahn and his employer, the University of California at San
Francisco. In light of such intimidation, few researchers will have the courage to
stand up to the companies that fund them.
Added to the problem of publication rights is the issue of how clinical research is
designed and executed. Pharmaceutical companies have designed studies to make
their drugs look more effective and less toxic than they really are. For example,
according to a 1994 Archives of Internal Medicine study, in 54% of company-sponsored arthritis-drug trials the dose of the funding companys drug was higher
than that of the comparison drug, increasing the likelihood that the funders drug
would appear more effective. Similarly, in the case of the diabetes drug Rezulin,
the Los Angeles Times recently reported that the manufacturer hid data showing
that the drug could cause liver failure. The drug was withdrawn after being the
suspected cause of 391 deaths.
Real patients suffer real harm from biased studies that offer false or incomplete
information, including information about a doctors financial ties to a
pharmaceutical company. Reform needs to begin with the clinical drug trial
process, where there must be some form of credible and independent third-party
testing of drugs. Additionally, scientists outside the walls of the manufacturing
company should have the final say on the design of drug trials. And all relevant
data must be made available to project investigators, and likewise to the subjects,
public, and press, whenever possible. Finally, all financial ties to interested
companies should be made public.
The public needs more safety and more information. The time has come for the
nations universities, medical centers, scientists, medical journals, and
governmental agencies the Food and Drug Administration and National
Institutes of Health to get together and advise lawmakers how to re-draw the
rules under which pharmaceutical products are tested and approved.
