The
cornerstone of public trust in medical research is the integrity of
academic institutions and the expectation that universities, which rely
on public funding, have a responsibility to serve the public good. Financial
conflicts of interest affect millions of American people - those
who are subjects of clinical trials testing new drugs and those who
are prescribed drugs after their approval. Yet, the leadership paid
little attention to the issue until a stream of tragic and unseemly
public revelations has shaken public trust in academic research.
In
January 2002, the Association of American Medical Colleges (AAMC) approved
a report by its task force stating: "Financial conflicts of interest
of clinical investigators... [is] the single issue that [ ] poses the
greatest threat to maintaining public trust in biomedical research."
[1] The report did not address institutional
conflicts of interest which create a culture that collides with the
humanist tradition.
Physicians
reading the current issue of JAMA[2] will be startled to learn that a team
of Harvard University professors are advising physicians NOT to prescribe
new drugs to their patients because their safety has not been established - despite
FDA approval. Adverse drug reactions,[3]
they acknowledge, is the leading cause of death in the U.S. They analyzed
the 25-year record of drug label changes (between 1975 to 1999) as they
appeared in the Physician's Desk Reference and found that 548 new drugs
were approved during that period. Of these 20% required subsequent black
box warnings about life threatening drug reactions, half of these adverse
effects were detected within 2 years others took much longer. Sixteen
drugs had to be withdrawn from the market because they were lethal.
The
JAMA report provides a basis for evaluating the value and relevance
of clinical trial findings for clinical care. It also provides a basis
for measuring FDA's performance as gatekeeper in preventing hazardous
drugs from reaching the market. They found that clinical trials are
underpowered to detect uncommon, but potentially lethal drug reactions.
Their design, biased selection, short duration, and accelerated approval
process almost ensures that severe risks go undetected during clinical
trials. The JAMA report validates the findings of a Pulitzer Prize winning
investigative report in the Los Angeles Times by David Willman.[4]
Willman
uncovered evidence demonstrating the adverse consequences of the 1992
Prescription Drug User Fee Act (PDUFA), the law that brought industry
money and industry influence to the FDA. The approval process for new
drugs was accelerated and the percentage of drugs approved by the FDA
increased from 60% approval at the beginning of the decade to 80% approval
by the end of the 1990s. Willman reported that the FDA was the last
to withdraw several drugs that had been banned by European health agencies.
There was a concomitant precipitous rise in the approval of lethal drugs:
between Januray1993 and December 2000, seven deadly drugs were brought
to market only to be withdrawn after they had been linked to at least
1,002 deaths.[5]
In a follow up article, August 2001, [6]
Willman reported that the list of lethal drugs withdrawn since Sept
1997 had jumped to a dozen - 9 had been approved after 1993.
None
of the drugs were for life-threatening conditions, one was a diet pill,
another for heartburn, another an antibiotic that proved more dangerous
than existing antibiotics. The approval of these drugs illustrates the
collision between corporate interests and the public interest. Corporate
interests revolve around maximizing profits through the marketing of
new, expensive drugs, but corporate interests collide with public safety
interests. FDA's "expert advisory panels" demonstrate FDA's
loss of independence. Most advisory panel members have undisclosed financial
ties to the manufacturer whose drugs they recommend for FDA approval.[4]
Corporate
influence in academia:[7]
Until
1980 a firewall existed separating industry and academia to ensure that
academic pursuits were independent of commercial influence. When the
Bayh-Dole Act of 1980 encouraged "technology transfer," that
firewall was removed, allowing federally funded universities to patent
and license inventions developed by faculty members. Researchers and
institutions were free to enter into ventures and partnerships with
biotechnology and pharmaceutical companies, and they did. It is estimated
that of the $55 billion to $60 billion spent by the biomedical industry
on research and development, large companies spend one fifth at universities,
small companies spend one-half.[8]
With the flow of corporate money, came corporate influence and control.
The culture within academic institutions changed: business ethics swept
aside the moral framework within which academia had functioned. Gone
were such niceties as intellectual freedom and a free and open exchange
of ideas, so was full disclosure of research findings. Gone was the
culture of social responsibility, or a social conscience. Finally, the
absence of independent, third party review has put the integrity of
the process and the quality of the products in jeopardy.
The
investigative series in the Seattle Times[9] provides insight into that changed culture at the
Fred Hutchinson Cancer Center during the mid 1980s. The copiously documented
series examined the conduct of research and patient care in two cancer
trials. It illustrates how a new entrepreneurial culture in medicine
encouraged doctors to push the limits beyond what can be considered,
ethical research, by subjecting patients to unjustifiable risks and
increased suffering. At the Hutch a physician with a conscience who
clearly did not embrace the new entrepreneurial ethos blew the whistle.
It
has been said, "Doctors fear drug companies like bookies fear the
mob."[10]
Researchers
whose findings collide with corporate interests, are finding out that
academic freedom is no longer operational. Two high profile examples
from our Canadian neighbors illustrate that researchers can face intimidation
by both corporate sponsors and university administrators. In 1996 Dr.
Nancy Olivieri[11] found that a generic drug for thalassemia,
manufactured by Apotex, the sponsor of the tirals, failed to sustain
long-term efficacy. Dr. Olivieri informed Apotex and the chair of the
institution's research ethics board (REB) and moved to inform patients
in the clinical trials of the risk-; as is her ethical obligation. Apotex
terminated the two trials and warned Olivieri of legal consequences
if she informed patients or anyone else. Apotex, meanwhile had reportedly
contributed $13 million to The University of Toronto.
When
Olivieri attempted to publish her findings, Apotex threatened to sue
her for breach of confidentiality. The University failed to defend Olivieri
and the principles of research ethics or academic freedom. The University
threatened to dismiss her, initiating a biased inquiry and knowingly
relied on false accusations by company- funded investigators - all of
which were later discredited by an independent investigation by the
Canadian Association of University Teachers.[11]
Olivieri's publication of her negative findings was delayed for two
years. The case is a dramatic illustration of conflicts of interest
and the collision between corporate interests and the right of research
subjects to be informed of any identified risks - as required by the
principle of informed consent.
Another
example of the clash between academic freedom and corporate interests,
again involving retribution by the University of Toronto, involves Dr.
David Healy,[12]
a prominent psychopharmacologist and historian of psychiatry at the
University of Wales. Healy had been hired to head the Mood Disorder
Program at the University's Center for Addiction and Mental Health.
The program is reported to get 52% of its funding from corporate sources,
and the Center received $1.5 million from Eli Lilly. After Healy criticized
the drug industry in an article published by The Hastings Center, Eli
Lilly withdrew its $25,000 contribution to Hastings. When Healy delivered
a paper expressing his concern about the risk of suicide in some patients
taking antidepressant drugs - such as Prozac-- the University rescinded
his appointment. Academic freedom is but one casualty of corporate influence.
As
Marcia Angell correctly observed [13] in her last editorial in the NEJM, corporate
influence in medicine is ubiquitous, extending far beyond individual
physician-researchers: its influence determines what research is conducted,
how it is done, and the way it is reported. Short-term corporate goals
take priority over society's long-term needs. Under corporate influence,
more research is done comparing trivial differences between one drug
and another, less research is done to gain knowledge about the causes
of disease.
The
pharmaceutical industry spends $15 billion[14] to buy loyalty
of health care providers and allied professionals-- educators, investigators,
and non-profit organizations. Drug companies shower physicians with
gifts, honoraria, global junkets, and provides fees for patient referrals
for clinical trials. They endow academic chairs and programs, provides
grants, stock equity, patent royalty fees to researchers and institutions--even
publication attribution is controlled by sponsoring companies. They
make contributions to professional associations and patient advocacy
groups, and sponsor their conferences.
The
American Medical Association sells the rights to its "physicians'
master file" with its detailed personal and professional information
on every doctor practicing in the United States, to dozens of pharmaceutical
companies for $20 million. [15] That database provides drug
marketers with invaluable information. Journals and the media profit
from drug advertising income. Such financial inducements assure industry
a fraternity of loyal allies, among them journal editors, who protect
their own interests and those of their corporate benefactors. For example,
the British journal, The Lancet, reported that the editor of the British
Journal of Psychiatry had published a favorable review of a drug while
he was receiving an annual fee of 2,000 (British pounds) from the drug's
manufacturer.[16] Although clinical
research is highly competitive, the interdependent collaborative network
of stakeholders tightly controls a self-administered opaque oversight
system.
The
pharmaceutical industry also buys political influence in Congress and
the administration. Public Citizen[17] reported that there are 625 pharmaceutical
industry paid lobbyists in Washington, one for every congressman. Industry
spent $262 million on political influence in the 1999-2000 election.
That's more than any other industry. This influence ensures the industry
profit enhancing legislation and reduced regulation. Since the 1992
Drug User Fee Act (PDUFA) which precipitated fast-track drug approval,
congress passed the 1997 FDA Modernization Act providing industry with
huge financial incentives - a six- month patent extension for drugs
tested in children. These legislative initiatives are a financial bonanza
for the drug industry, translating into billions of dollars in revenues
- a six month patent extension can generate as much as $900 million
for a single drug.[18].
However,
the accelerated pace in research and in the drug approval process has
had an enormous toll in human casualties. Adverse drug reactions are
the leading cause of death in the United States - women and the elderly
are at special risk.[19] The LA Times revealed that between Sept. 1997 and
Sept. 1998, nearly 20 million Americans took at least one of the harmful drugs
the FDA had been forced to withdraw.[4]
A comparison of FDA's 25 year drug approval-withdrawal record analyzed
by Lasser, et al,[2]
in JAMA, and the LA Times analysis of FDA's recent five year record
raises alarms: 16 drugs withdrawn within 25 years, 12 within five. Most
of those withdrawn drugs had been approved after 1993. The LA Times
noted, "never before has the FDA overseen the withdrawals of so
many drugs in such a short time."
Since
1994, reports in the press described ethical violations that undermined
the safety of subjects in clinical trials, causing some to die when
they might have lived.[20] The violations occurred because
a culture of expediency had replaced a culture of personal moral responsibility.
Systemic ethical violations were revealed at the nation's leading research
centers[21] - including, Duke,
University of Pennsylvania, New York Cornell Medical Center, Johns Hopkins,
Fred Hutchinson, NIMH, University of Maryland, and Harvard in China.
The evidence demonstrates that the problem is not merely a few rogue
investigators-- the problem is an entrenched insular system and weak
federal oversight.[22] The federal Office of Protection from Research
Risks (now, OHRP) was forced (temporarily) to shut down clinical trials
at some of the nation's most prestigious institutions.[23]
In
September 2000, near the end of her term as Secretary of HHS, Donna
Shalala acknowledged in NEJM, "I did not expect, or want, to complete
my tenure . . . by raising questions about the safety of patients in
clinical research. However, recent developments leave me little choice.
. ."[24] Unfortunately, the only initiative taken was to
reorganize the federal oversight agency (now OHRP) under a new director
who believes that education and a collaborative system of voluntary
accreditation will repair the damage.[25]
I disagree. Ethical violations such as failure to disclose risks and
to protect the welfare of patient-subjects are the result of conflicts
of interest - not poor education.
An
example of complicity by government officials who provide a shield of
secrecy, while claiming "transparency:" On February 7, 2002,
the Alliance for Human Research Protection[26] requested a copy
of current proposals that have been received by the Secretary of HHS
in accordance with Section 407 of federal regulations (45 CFR 46. Subpart
D). Subpart D protects children - who are incapable of exercising the
right to informed consent-- from experiments involving greater than
minimal risk if there is no potential benefit to them. However, section
407 provides an appeal process to the Secretary. The regulation stipulates
that nontherapeutic research with no potential direct benefit to the
child, may be permitted if the Secretary, after consultation with "a
panel of experts in pertinent disciplinesand following an opportunity
for public review and comment" finds "the research presents
a reasonable opportunity to further the understanding, prevention or
alleviation of a serious problem affecting the health or welfare of
children."
Our
request was denied with the following statement:[27] "Release of information would interfere with
the agency's deliberative and decision-making processes. Further, each
researcher has a commercial and privacy interest in the release of any
information." A similar reason was given for denying disclosure
of the list of experts: "Release of expert identities associated
with the review of individual protocols would interfere with the agency's
deliberative and decision-making process and have a chilling effect
on the ability of the agency to obtain frank and candid opinions from
its reviewers." This is an example of federal officials attempting
to block public access to information guaranteed under federal regulation.
The
role IRBs and bioethicists have in this enterprise:
Ostensibly,
IRBs were established to serve as gatekeepers to protect human subjects.
But lacking independence, they actually function as facilitators for
the accrual of grant monies by their parent institutions. It is not
surprising, therefore, that IRBs have failed to protect research subjects
from harmful experiments or to weed out research that fails to meet
scientific justification. Specifically, what conclusion is one to draw
from the fact that 90% of the protocols approved by the IRB at the NIMH,
apparently failed to meet either ethical and / or scientific justification?
Following an investigative series in The Boston Globe,[28] in 1998, the director of NIMH ordered
an independent evaluation of all 89 clinical trials at the Institute.
The result: 29 were suspended at once, and an additional 50 protocols
were put on probation for lack of scientific justification - that's
79 out of 89.[29]
In
"Pharma Buys a Conscience," Dr. Carl Elliott, [30]
director of the Bioethics Center, Minnesota, (who happens to be a physician)
is an insightful critical examination of bioethics. Elliott criticizes
his colleagues who have been seduced by corporate financial incentives.
He points out how conflicts of interest have undermined the professional
integrity of bioethics. He lists ethics consultants and their corporate
benefactors,[31] as well as what he calls, "corporate-academic
dating services" that match academic "experts" with businesses
seeking expertise. He notes that corporate money and corporate influence
is so entrenched at university medical centers that overt threats need
not be explicitly made, everyone knows what's expected. Bioethicists
are in demand because they lend the appearance of legitimacy to corporate
ventures. Therefore, corporations funnel money to bioethics centers,
and pay bioethicists retainers to serve on their advisory boards. But,
as Elliott points out, "The problem with ethics consultants is
that they look like watchdogs but can be used like show dogs."
Indeed,
bioethicists have lent the seal of legitimacy to highly questionable,
if not outright unethical research. Their corporate affiliations are
not publicly disclosed when they render opinions in the media or on
IRBs, or on government advisory panels. An institutionalized veil of
secrecy shields academics who sit on government appointed advisory panels.
While their recommendations affect public policy, those recommendations
may also serve the financial interests of the corporations that pay
them.
In
1997, I testified before the National Bioethics Advisory Commission
(NBAC) about financial conflicts of interest, betrayal of trust, and
the undue influence of drug companies in medicine. I pointed out that
physicians who accept large payments to refer patients for clinical
trials testing the safety and efficacy of new products are breaching
medical ethics. The Wall Street Journal, for example, reported that
doctors with academic affiliations have been paid as much as $30,000
per patient per drug trial[32] in schizophrenia and Alzheimer's
studies.
Following
the testimonies, Dr. Harold Shapiro, chair of the NBAC and President
of Princeton, indicated that the NBAC would not focus on financial arrangements
of research investigators because, "after all, this is a capitalist
country." Dr. Shapiro neglected to mention that he was drawing
a salary from Dow Chemical Company, on whose advisory board he sat.[30]
Such publicly undisclosed personal financial arrangements by academics
who sit on public policy advisory boards are not at all unusual. The
public is under the illusion that so-called "expert advisory panels"
are independent, and render objective, disinterested recommendations.
The public does not suspect that these panelists from academia have
financial ties to biochemical companies, and therefore, conflicts of
interest. No one is held accountable for formulating public policy recommendations
that serve an undisclosed self-interest.
What
chance does a vulnerable individual patient have as an outsider confronting
a fraternity of insiders - all of whom have something to gain from his
participation as a subject? The system serves its stakeholders. Revelations
about the system's failure to protect human subjects from preventable
harm have come to light, not because of any internal safety mechanisms,
but as a result of information provided by conscientious whistle blowers
and investigative press reports.
Following
are my "dirty dozen" corrupt research review practices that
undermine both the safety of human subjects and the integrity of research
findings:
1. Efficacy by design: washout
/ placebo; unequal dose comparison = bias.
2. Subject selection bias:
younger, healthier subjects than those likely to be prescribed treatment;
randomization criteria; recruitment coercion.
3. Assessment of risk /
benefit: entirely subjective, it depends who is assessing.
4. IRB evaluation and approval
process: vote without examination of protocol; intimidation; IRB
shopping.
5. Misleading disclosure
documents = Uninformed Consent.
Non-disclosure:
there's no benefit; newly identified risks = Uninformed Consent.
6. Suppressing adverse event
reports: "don't ask, don't tell"
7. Interpretation of findings--"efficacy
in expert hands is not the same as clinical effectiveness"[33]
8. Biased advisory panels:
FDA panels recommend drugs that kill.
Bioethics
ethics: conscience for hire;
9. Professional
guidelines, recommendations.
10. Corrupted published data:
suppression of negative findings; ghost authorship.
11.
Complicit government oversight officials fail to enforce, preferring
to redefine the standards: Who is a human subject? What's a condition?
Can children's assent be called consent?
12.
Using patients as laboratory animals in symptom provocation, relapse
inducing experiments.
Case
1: Placebo design: ethics vs financial stakes
Corporate
influence begins with the protocol design and subject selection. For
example, unequal dosage comparisons will elicit different side effects
that may skew the results. Selective inclusion criteria can effectively
hide adverse side effects that will later be reveled in clinical practice.
Drug "washout' followed by placebo allows sponsors to manipulate
the condition under which a new drug is tested. Specifically, by making
patients very sick during washout, the efficacy of the new drug is likely
to be inflated. Such manipulations may explain the reason that a drug's
efficacy in clinical trials is not usually matched under normal clinical
conditions.
The
use of placebo control trials in patients for whose condition an effective
treatment exists has been the subject of heated debate. The FDA has
been severely criticized for its placebo control policy because it undermines
patient's best interest in violation of the Declaration of Helsinki.
Of particular concern is the risk of suicide in severely depressed or
psychotic patients who are at increased risk when their condition is
destabilized by drug "washout" and placebo. They are at risk
whether the drugs are an effective treatment or not because psychotropic
drugs are associated with severe withdrawal symptoms.
Carl
Elliott described his battle with the university's IRB when he challenged
placebo control trials: "Tables were pounded. Faces turned scarlet.
Blood pressures soared. Yet the IRB continued to approve many of the
trials, over my objections and those of other members of the committee.
The hospital administration eventually dissolved the IRB and reconstituted
it with new membership."[26]
Elliott explains that the reason for the explosive reaction was that
"everyone's interests were involved" - not just the sponsoring
drug company. These trials generated huge income for the hospital and
investigators alike, some earning between $500,000 and $1 million a
year.
Case 2: Biased
Clinical Guidelines:
An
investigative report by Jeanne Lenzer[33]
in the British Medical Journal (March 2002) sheds light on the underlying
factors that led the American Heart Association to "definitely
recommend" a treatment that could cost more lives than the disease
itself. In August 2000 the Heart Association promoted alteplase (tPA),
manufactured by Genentech, as a treatment for "brain attack."
The Association upgraded its recommendation of tPA for stroke, placing
it in the class I category. It did so despite the fact that most controlled
trials showed that such thrombolytics increase mortality rates
in acute ischaemic stroke. In it's annual report it described tPA
as follows: "A clot-busting drug that helped revolutionize heart
attack treatment, tPA holds enormous potential for the treatment of
ischemic stroke, which accounts for 70 to 80 percent of all strokes.
It is estimated that tPA could be used in 400,000 stroke case per
year to save lives, reduce disability and reverse paralysis."[33]
The
Heart Association made its bold recommendation on the basis of a single
controlled clinical trial conducted by the National Institute of Neurological
Diseases and Stroke (NINDS). Six other randomized studies reached the
opposite conclusion. Lenzer reported the following: the NINDS study
design ensured a favorable finding for tPA because the patients selected
to get tPA had mild stroke scores at baseline compared with patients
selected for the placebo arm who had worse strokes. Furthermore, only
one fifth of those initially diagnosed were found to have stroke. This,
of course put those non-stroke patients at increased risk of harm with
no potential benefit. There were two observational studies reaching
opposite conclusions. The Cleveland study found that twice as many
patients given tPA died compared with those that did not.
Most
suspicious of all, however, is the refusal by NINDS to reveal the raw
data for that single trial. Lenzer's request under the Freedom of Information
Act was rejected. Furthermore, the company vigorously opposes a head
to head study comparing alteplase to streptokinase for myocardial infarction.
Dr. Elliott Grossbard, a Genetch scientist, provided the company's position:
"We don't know how another trial would turn out[another study]
may be good for America, but it wasn't going to be a good thing for
us."[34]
The
panel of experts who wrote the Heart Association's Clinical Practice
Guideline recommending tPA failed to mention the catastrophic results
from the Cleveland study. According to the BMJ article, eight of the
nine expert panel members had financial ties to the manufacturer,
Genentech. Dr. Jerome Hoffman, the single panel member who did not
have ties to Genentech wrote a dissenting opinion that was not even
acknowledged by the panel. Hoffman questioned the tPA endorsement
in a BMJ article, charging that the NINDS findings were artificially
manipulated to exclude 95% of stroke patients.[35]
Lenzer
reported that Genentech had contributed over $11 million to the Heart
Association and also paid $2.5 million to build the Heart Association
a new headquarters. Only after the these financial conflicts of interest
became public knowledge, did the Heart Association revise its class
I recommendation and withdraw statements that tPA "saves lives."
The
Heart Association is hardly unique: a recent report in JAMA[36]
(2002) found that 87% of the authors who wrote treatment practice guidelines
in all fields of medicine had financial ties with the pharmaceutical
industry. In 1998 the NEJM found that 96% of medical journal authors
whose findings were favorable to a product had financial ties to the
manufacturer.[37] As questions have
been raised about the value of mammography and other cancer screening
recommendations, one grows suspicious that most highly publicized screening
campaigns are launched by stakeholders with financial interests in the
business. Their recommendations may turn out to be hazardous to public
health.
Case
3: Subject selection bias--antidepressant drug trials:
Dr.
Thomas Laughren, head of the FDA's psychiatric drug division made the
following concessions at a Houston conference (2000): "there is
a certain amount of myth" in the claimed efficacy of psychotropic
drugs which have shown only marginal effect above placebo. "We
don't know how effective they are, only that in clinical trials, they
demonstrated somewhat greater efficacy than placebo." He then acknowledged:
"there isn't any standard for what effect size is required to get
a psychotropic drug on the market.we have never, in my experience,
not approved a drug because of a finding that the effect size is too
marginal."[38]
To
obtain even a marginal effect above placebo, 60% to 85% of patients
who are most likely to be prescribed antidepressant drugs are excluded
by the eligibility criteria. That's the finding of a Brown University
analysis[39]
of 31 antidepressant trials published from 1994 to 1998. Only 15 percent
of 346 depressed patients who were evaluated in a Rhode Island hospital
psychiatric clinic would have met the eligibility requirements of a
standard drug trial. Such a selection process inevitably skews the results,
thereby invalidating the published findings and claims about the efficacy
of antidepressants. Zimmerman expressed concern: "If antidepressants
are, in fact, not effective for some of these large subgroups of depressed
individuals, their prescription incurs an unjustifiable exposure of
risks and side effects, and alternative treatments need to be considered."
I
would also argue that if the patients in clinical trials don't resemble
the patients who are later prescribed these drugs - what relevance do
the trials have for clinical care?
Case
4: Antidepressant drug efficacy hype:
A
report in the April 10, 2002 issue of JAMA by prominent psychopharmacologists
who conducted a major government sponsored, [40]
12 -site, controlled clinical trial comparing sertraline (Zoloft), Hyperricum
perforatum (St. John's wort) and placebo. The investigators acknowledged:
"An
increasing number of studies have failed to show a difference between
active antidepressants and placebo. Many of the presumed factors underlying
this phenomenon were carefully attended to in this study, e.g, adherence
to quality control by rater training, treatment adherence monitoring,
inclusion of experienced investigators, and carefully defined entry
criteria. Despite all of this, sertraline failed to separate from placebo
on the two primary outcome measures"
Between
December 1998 and June 2000, 340 Adult outpatients with major depression
and a baseline total score on the Hamilton Depression Scale (HAM-D)
of at least 20 were recruited and randomly assigned to receive (900
to 1500 mg) St. John's wort, (50 to 100 mg) Zoloft, or placebo for 8
weeks. Responders at week 8 could continue blinded treatment for another
18 weeks. The results of this trial states: "on the 2 primary
outcome measures, neither [Zoloft] nor [St. John's wort] was significantly
different from placebo." Full
response occurred in 31.9% of the placebo-treated patients vs 23.9%
of the [St John's] - treated patients and 24.8% of [Zoloft]-treated
patients."
Clearly
a dual dilemma faces those who are invested in promoting psychopharmacolgy:
if they admit that the drugs don't really work, then placebo-controlled
trials are ethically justified. However, absent a demonstrable benefit
of the drugs, it is unethical to expose patients to the known side effects
and the potential long-term risks of harm. But such an acknowledgement
would undercut the financial interests of the pharmaceutical industry
and all of the stakeholders who depend on corporate largesse. The
prominent psychiatrists, whose names are too numerous to be listed at
the head of the JAMA article, found a way to spin the negative results
of the trial. In their conclusion they ignore their own findings,
namely, that neither the antidepressant drug, Zoloft, nor
St. John's wort were more effective than placebo. Indeed, placebo may
have an edge. In their conclusion the investigators pretend that
Zoloft was not part of the 3-arm trial: "This study fails to support
the efficacy of H perforatum in moderately severe major depression."
An
accompanying JAMA editorial by Dr. David Kupfer,[41] past president of the American College
of Neuropsychopharmacology, also puts a spin on the findings:
"The
current study on the use of St John's wort in the treatment of MDD
is the second one within a year to conclude that St John's wort is not
effective. These trials were conducted because, even though St John's
wort is widely used for the treatment of major depression and depressive
symptoms, its efficacy has not been clearly established"
How
could these prominent leaders of psychiatry draw a conclusion
that contradicts the study findings? In compliance with JAMA's
conflict of interest disclosure policy, a long list appends the article
disclosing some of the authors' financial ties to industry - it speaks
for itself.
A
troubling question arises: Why did the editors of JAMA fail to seek an
independent evaluation of the research findings? Why did JAMA select
a psychiatrist whose financial ties include membership on the advisory
board of Pfizer, the drug company whose product was being reviewed?
[42]
Case
5: Undisclosed negative data:
An
editorial in the British Medical Journal by Richard Smith, "Maintaining
the Integrity of the Scientific Record,"[43]
stated: "We editors of medical journals worry that we sometimes
publish studies where the declared authors have not participated in
the design of the study, had no access to the raw data, and had little
to do with the interpretation of the data. Instead the sponsors of the
study - often pharmaceutical companies - have designed the study and
analyzed and interpreted the data. Readers and editors are thus being
deceived."
Even
when a legitimate physician who does not have financial conflicts of
interest reviews a study, there is no assurance that the process has
not been corrupted. Here is an example: in 2001, Dr. Michael Wolfe was
asked to write an editorial in JAMA about the findings of a six -month
study testing the arthritis drug, Celebrex, on more than 8,000 patients.
[44]
The editors sent him the manuscript reporting indicating they were anxious
"to rush the findings into print." Based on the data reported
in the manuscript, Wolfe wrote a favorable review. When he later saw
the complete data - as a member of an FDA advisory panel-- he was "flabbergasted."
To his embarrassment he discovered that the study had actually been
a year long, and when all the data was evaluated, Celebrex offered no
proven safety advantage over two older drugs in reducing the risk of
ulcers. He also learned that the study's 16 authors included faculty
members of eight medical schools - they were all employees of the manufacturer,
Pharmcia, or paid consultants. JAMA's editor, Catherine DeAngelis, is
quoted in the Washington Post, saying: "We are functioning on a
level of trust that was, perhaps, broken."[31]
Peer review and the integrity of medical guidelines and the scientific
literature have all been corrupted by the corrosive influence of industry.
Case
6: The 1997 "pediatric rule" puts children's lives at risk:
Children
are being sought to serve as "risk bearing subjects" to risk
their lives to test drugs. For example, the FDA approved a pediatric
trial exposing 100 children to Janssen Pharmaceutica's heartburn drug,
Propulsid.[45] FDA approved the trial and allowed babies to be
enrolled even after the drug had been linked to sudden deaths. The babies
who were recruited were diagnosed with gastroesophageal reflux - a condition
hardly considered life-threatening. Doctors say that most babies outgrow
the problem by their first birthday. Among the casualties was a 9-month
old infant, Gage Stevens. He was recruited by researchers at the University
of Pittsburgh. According to press reports the parents only learned about
the risks associated with Propulsid from an Associated Press report
AFTER their baby was dead.
The
LA Times reported that Propulsid's danger to the heart was identified
as early as January 1995, when FDA's senior gastrointestinal expert
informed Janssen executives that recent adverse-reaction reports showed
their drug was prolonging the QT interval, perhaps resulting in deaths.
The British Medicines Control Agency (BMCA) had warned against any use
of Propulsid in infants since 1998, and cautioned against prescribing
it to children up to age 12. The consent form given to the parents falsely
indicated that the FDA had approved Propulsid for children. The parents
said the doctor conducting the clinical trial was adamant that Propulsid
was the best treatment for their child. The parents said they would
never have consented, had they known of the previous deaths. The mother
was quoted by CBS News, exclaiming: "It's like giving you chemotherapy
for a toothachethe benefits just don't outweigh the risks. I mean,
it's reflux! It's not something that's (going to kill him)."[46]
The final blow was delivered when the baby's parents learned from the
autopsy report that Gage's esophagus did not show any signs of "significant
inflammation or other hallmarks of gastroesophageal reflux."[47] In other words,
the baby didn't have the condition for which he was entered as a subject
into a fatal clinical trial.
A
spokesman for Janssen (a Johnson & Johnson subsidiary) indicated
that the company did not promote Propulsid for use by children. However,
the LA Times reported, the company acknowledged that it did make two
"educational grants" to the North American Society for Pediatric
Gastroenterology and Nutrition. The society's literature advised doctors
that Propulsid could be used safely and effectively in children.
FDA
did not pull the drug off the market even as the death toll rose. In
December 2000, the LA Times reported that overall Propulsid has been
cited as a suspect in 302 deaths. FDA administrators now concede that
the agency failed to contain Propulsid's fatal risk. In comments to
an FDA advisory committee in June 2000, FDA's Dr. Florence Houn said:
"The labeling probably was not effective." In the end, it
was not government intervention that forced Janssen to stop marketing
Propulsid in the U.S., it was litigation. I question the wisdom of a
policy that encourages the use of children in drug trials BEFORE the
safety and efficacy of the drugs have even been established in adults.
Case
7: Children exposed to risks in psychotropic drug trials:
Psychotropic
drugs are being tested in children despite the acknowledged risks of
harm. Psychotropic drugs are advertised as normalizing a "chemical
imbalance" in the brain. In fact, they do the opposite: they induce
profound changes in the central nervous system with demonstrable physical
and neurological impairments.[48]
Dr. Steven Hyman, former director of NIMH, an expert on the mechanisms
by which psychoactive drugs work, explained that, whether abused or
prescribed, the mechanisms by which psychoactive drugs work are the
same.[49]
Hyman stated that antidepressants, psychostimulants, and anti-psychotics
created "perturbations in neurotransmitter function."[50] The drugs' severe adverse side
effects are symptoms of the drugs' disruptive effect on the neurotransmitter
system and on brain function.
In
2001 Dr. Benedetto Vitiello, NIMH's director of Child and Adolescent
Treatment and Preventive Interventions Branch acknowledged the impact
of FDAMA: "pediatric psychopharmacology has recently seen an unprecedented
expansionclinical trials in youths has more than doubled in the last
few years."[51]
Indeed, children as young as three are being recruited to test mind-altering
drugs that may affect their developing brain. Parents are being offered
financial inducements to volunteer their children for drug trials. The
foremost problem with prescribing or testing psychotropic drugs for
children is the absence of any objective criteria for diagnosing children
with pathological behavioral problems to justify pharmacologic intervention.
Vitiello acknowledged "diagnostic uncertainty surrounding most
manifestations of psychopathology in early childhood."[52] Vitiello also acknowledged the possibility of long-term
harm: "The impact of psychotropics on the developing brain is largely
unknown, and possible long-term effects of early exposure to these drugs
have not been investigated."
Eli
Lilly's highly touted new anti-psychotic, Zyprexa,[53] reveals much about the collision
between corporate interests and the health and safety of children. In
clinical trials averaging 6 weeks, Zyprexa was tested in 2,500 adults.
The drug was linked to serious, in some cases life-threatening side
effects requiring hospitalization in 22% of those tested.[24]Acute
weight gain of 50 to 70 lbs is usual, and with it the increased risk
of diabetes. FDA data (under FOIA) reveals a 65% drop out rate, and
only 26% favorable response. During those 6 week clinical trials
there were 20 deaths, of which 12 were suicides.[54] David Healy, who found a suicidal
link to antidepressants (Selective Serotonin Reuptake Inhibitors) in
his research says, as far as he can establish, the data from these trials
"demonstrate a higher death rate on Zyprexa than on any other
antipsychotic ever recorded." [55] In 2000, FDA approved
Zyprexa for short- term use only, in bi-polar patients.[56]
Yet,
children aged six to eleven were recruited for clinical trials to test
the drug. According to their published report, UCLA investigators tested
Zyprexa on children who were not even diagnosed as having schizophrenia.
The children were diagnosed as having a variety of questionable psychiatric
disorders, including ADHD.[57]
According to the published report, all the children in the trial experienced
adverse effects, including sedation, acute weight gain, and akathisia
(restless agitation). The trial was terminated less than six weeks after
it had begun.
Controversy
surrounds a Zyprexa trial at Yale University. In that experiment, 31
youngsters aged 12 to 25 who have not been diagnosed with any psychiatric
illness are being exposed to the drug for one year. The stated rationale
given by the researchers (who are under contract with he sponsor) is
their speculation that these children may be "at risk" for
schizophrenia. Since there are, as yet, no objective tests or biological
markers for the illness - they hypothesize without evidence,
merely on the basis of conjecture. The shaky basis for their conjecture
is that assumption that the children may develop schizophrenia because
one of their siblings has been diagnosed with the disorder.
The
risk of schizophrenia for the general population is 1%. For siblings
the risk increases from 2% to 15% - in other words there is 85% likelihood
that these children will never develop schizophrenia.
Given
the absence of scientifically accurate tools for interpreting psychiatric
symptoms, psychiatrists cannot as yet accurately diagnose schizophrenia
much less predict which children will get it. Is it ethical to expose
healthy children to risks of drug- induced pathology on such speculation?
The Wall Street Journal aptly noted that such a study "raises
the question of whether the drug companies are mainly interested in
"creating" a new illness that requires drug treatment."
Conflicts
of interest in clinical trials result in deadly medicine:
Conflicts
of interest have corrupted the soul of the American university, the
ethics of medicine, the integrity of the scientific record, and the
safety of patients who serve as human subjects in pre- and post-marketing
clinical trials. Adverse drug reactions in FDA-approved drugs are the leading
cause of death in the United States.[2],
[3]
The JAMA report advises physicians against prescribing new drugs "unless
they represent an important medical advance" because newly approved
drugs are likely to be unsafe - even lethal. The JAMA report corroborated
the findings of the LA Times earlier report: in some cases FDA approved
new drugs despite pre-marketing evidence indicating potential danger.
In his editorial in JAMA, FDA's Dr. Robert Temple attempts to disavow
agency responsibility, while acknowledging: "Premarketing trials
in a few thousand (usually relatively uncomplicated) patients do not
detect all of a drug's adverse effectsand sometimes the postmarketing
discoveries cause the drug to be withdrawn."[58]
Why
did the FDA's track record of protecting the public from unsafe drugs
worsen since 1993? The answer is undue corporate influence and a tainted
drug testing and approval process that has compromised the safety of
both clinical trial subjects and patients in clinical care. The absence
of independent, third- party reviewers has undermined the safety of
the drug development and approval process. A tainted process has led
the FDA to approve deadly drugs that killed patients while enriching
those drugs' manufacturers. The LA Times reported that seven lethal
drugs that were ultimately withdrawn between 1997 and 2000, generated
$5 billion in sales. It remains to be seen how the American public will
react to the revelation that new drugs are less safe than old drugs.
How will Americans respond to the revelation that when they take a new,
FDA-approved drug, they are essentially testing the drug's safety? Public
trust is not likely to be restored until the integrity of the process
and the institutions is restored through independent unbiased review.
When the condition is life-threatening, or when the new drug offers
a significant advance over existing treatments, the risks may be justified.
But no one should have to die from a heartburn drug or a diet drug.
