Drug Trials Hide Conflicts for Doctors - Part I
By KURT EICHENWALD and GINA KOLATA
May 16 1999
http://www.lawyer.com/articles/article2321.cfm
When Thomas Parham visited his doctor in the summer of 1995,
he expected just another routine checkup.
But his doctor had something else in mind.
The doctor, Peter Arcan, suggested that Parham might want to
join a
study
of a new drug to shrink enlarged prostates, according to records
of the
encounter.
Parham was puzzled -- his prostate was fine.
But Arcan brushed aside the retired metal worker's questions,
saying the experimental drug might prevent future problems.
Satisfied, Parham, a 64-year-old resident of La Habra, Calif.,
agreed to
participate.
There was one question Parham did not ask:
What was in it for Arcan?
The answer was money.
The drug's maker, SmithKline Beecham PLC, was paying $1,610
for each patient that doctors signed up --
money that covered study expenses
while allowing a portion to end up as profit for Arcan and his
associates.
Parham had no idea.
"Nothing was mentioned about money," he said in an interview.
"It's a situation where you have faith in your doctor."
Through his secretary, Arcan declined comment.
With his decision, Parham had unwittingly joined hundreds of
thousands
of other patients recruited by their personal physicians
into a booming venture:
the business of testing experimental drugs on people.
Once clinical research was a staid enterprise
primarily administered by academic researchers
driven by a desire for knowledge, fame or career advancement.
Now, it is a multibillion-dollar industry, with hundreds of
testing and
drug companies
working with thousands of private doctors.
In this new industry, patients have become commodities,
bought and traded by testing companies and doctors.
Almost daily, the industry urges doctors to join the gold rush,
bombarding them with faxes and letters blaring such come-ons as
"Improve Your Cash Flow" and "Discover the Secret For Obtaining
More
Funded Studies."
In an era of managed care, the pleas are seductive:
The number of private doctors in research since 1990 has almost
tripled,
and top recruiters can earn as much as $500,000 to $1 million a
year.
This new system is a boon for drug companies
because it reaches out to a vast pool of test subjects
who have never before been available for experimentation.
But it also injects the interests of a giant industry
into the delicate doctor-patient relationship,
usually without the patient realizing it.
These changes have prompted little public debate,
mostly because the full scope of what is happening is hidden.
The industry treats research agreements as corporate secrets
and contractually forbids doctors to disclose them.
As a result,
few people outside the industry, including government officials,
have seen the contracts or know the magnitude of the money
involved.
But in a 10-month investigation, The New York Times obtained
such
contracts
and thousands of other confidential documents that present a
view
of the research industry that has never before been available.
These records, and interviews with participants,
reveal a system fueling a pharmaceutical renaissance,
but fraught with conflicts of interest;
that places a premium on speed and meeting quotas;
that relies on government and private monitoring that can be
easily
fooled
and that some researchers said is inadequate;
and that secretly offers a share of the cash to other health
professionals
who might influence patients to join a study.
At bottom, the only thing separating a trusting patient from a
study
that could be inappropriate or potentially harmful
is the judgment of a doctor torn by these unseen conflicts and
pressures.
The documents, including contracts, protocols or related
financial
records
from more than 300 recent drug studies,
were provided by a number of people in the industry concerned
about its
direction.
The Times also conducted a computer analysis of more than
200,000
filings
with the government and related data submitted by doctors
who want to conduct research, and interviewed doctors, patients,
ethicists,
industry executives and government officials.
These are among the specific findings of The Times'
investigation:
-- Drug companies and their contractors offer large payments to
doctors,
nurses
and other medical staff to encourage them to recruit patients
quickly.
And doctors do not even have to conduct trials to get paid:
There are finder's fees for those who refer their patients to
other
doctors
conducting research.
-- Doctors who recruit the most patients receive additional
perquisites,
such as the right to claim a coveted authorship of published
papers
about the studies --
even though the true author is a ghostwriter using analysis from
the
drug company.
Those who fail to meet the recruitment goals are usually dropped
from
future studies.
-- Testing companies often use doctors as clinical investigators
regardless of their specialty, at times leaving patients in the
care of
doctors
who know little about their condition.
For example, psychiatrists have conducted Pap smears
and asthma specialists have dispensed experimental psychiatric
drugs.
-- A growing number of doctors conducting drug research
have limited experience as clinical investigators,
raising questions among some experts about the quality of their
data.
In interviews, industry officials and researchers said the
emerging
drug-approval system
was dedicated to quality and offers significant benefits.
Since patients are seeing their own doctors, researchers said,
it adds a level of continuity and personal contact to the
process --
something unavailable from full-time researchers.
Moreover, industry officials said, the new pool of test subjects
is a resource of incalculable value that is allowing the
development
of an avalanche of new compounds.
Drug tests "can get delayed if the patients aren't out there and
available,"
said Chris Kuebler, the chairman and chief executive at Covance
Inc.,
a giant testing company.
But some experts said patients were being pushed to participate
in the
studies
because of the financial interests of their doctors.
Doctors working as researchers "are enticing and cajoling
patients
who are in no position to resist their blandishments to enter
clinical
studies,"
said Dr. David Shimm, a member of the ethics committee at Porter
Adventist Hospital
in Denver who has written about research conflicts.
"What the patients are not seeing is that the clinical
investigator
is really a dual agent with divided loyalties
between the patient and the pharmaceutical company,"
he said.
While patients must sign detailed consent forms to enroll in
drug
studies,
they are often in no position to question their doctor's
suggestion
that they join.
"The physician has enormous power over you," said Uwe Reinhardt,
a health care economist at Princeton University,
who himself recently agreed to participate in a clinical trial
run by
his doctor --
in part because he feared annoying him --
and who had no idea that money might be involved.
"You want to keep his favor.
If you say no, you'll worry that he may not like you."
That is what happened with Parham and Arcan.
In joining the study, Parham said: "I just followed his advice,
just like if he said to take two aspirin instead of one.
He's a doctor and I'm not."
In truth, Parham should never have been signed up for the
prostate
study.
According to his medical records, he had been hospitalized the
previous
year
with a chronic slow heart rate, a condition that specifically
disqualified him for the study.
But, saying that Parham's heart rate was only mildly slow,
an administrator handling the paperwork for Arcan sought an
exemption
from SmithKline. Based on those representations, the drug
company
granted the exemption;
it was not told about Parham's earlier hospitalization.
Soon after joining, Parham complained of fatigue,
a symptom of his slow heart rate.
Arcan dismissed the complaints as emotional.
Within weeks, Parham asked to be dropped from the study.
Days later he was hospitalized and given a pacemaker;
Parham never brought legal action
and it is impossible to know whether his participation in the
study
affected his heart condition.
His experience underscores a potential danger of the emerging
drug-testing system:
Doctors with money at stake may persuade patients to take drugs
that are inappropriate or even unsafe.
Under the current system of monitoring, such actions are almost
impossible to catch
and no statistics are collected on such events.
Within the industry, most of the planning focuses on conducting
studies
quickly.
Patient issues, some researchers said, are often lost in the
rush.
"You go to the trade meetings on clinical research;
you go for two entire days, and patients are not mentioned,"
said Dr. Robert Califf, the director of the Duke Clinical
Research
Institute,
an academic drug- testing center in Durham, N.C., affiliated
with Duke
University.
"The patient is an object to make money.
Having patients is just the dirty price for doing business."
A letter sent out last July by Merck & Co. was nothing if not
sympathetic.
The company recognized that doctors involved in its study of a
hypertension medication
were having trouble finding qualified patients.
And so, with the letter, Merck offered a little encouragement
for them
to work harder.
Instead of paying $2,955 for each test subject enrolled,
Merck offered $500 more in the study comparing the drug Losartan
with a
placebo.
For those doctors who enrolled their quota of 14 patients by
Sept. 30,
the company would kick in an additional $2,000 --
making that 14th patient worth $5,455 if recruited in time,
and the entire group potentially worth more than $50,000.
"We will forward the first check as soon as the first four
additional
patients are enrolled,"
the letter said.
After discovering how effective paying doctors to recruit
patients
can be,
the drug industry has opened the financial floodgates.
Special cash bonuses for signing up specified numbers of people
by a
given date,
a practice once unheard of in clinical research,
are becoming part of the landscape.
Moreover, those payments -- to private doctors, research firms
and even to university medical centers --
are only one of a number of incentives dangled by drug and
testing
companies
to entice the medical community.
There are payments to everyone in the system who can come up
with a
patient,
from other doctors who refer them for research
to the study coordinators in the researcher's office
who screen patients to see if they qualify.
None of these benefits are scrutinized by government regulators,
who said in interviews that they saw no difference
between providing grants for university research
and paying doctors directly.
For academics "the money is just as important as with the
internal
medicine guy
trying to beat the HMO,"
said Dr. Murray Lumpkin, the deputy director of the Center for
Drug
Evaluation
and Research at the Food and Drug Administration.
But unlike block grants,
today's incentives can grow almost day by day,
if the doctor works the way the drug companies want.
And the variety of the incentives is almost endless.
The most basic form of compensation is a flat fee paid for each
patient enrolled.
The amount of money paid to the researchers varies widely,
depending on the complexity of the study, the number of tests
involved
and the difficulty in finding patients.
For example, in 1996, a study of a migraine drug
sponsored by Janssen Pharmaceutica, a unit of Johnson & Johnson,
paid doctors $3,600 for each enrollment.
Another study that year sponsored by Organon Inc. on a new birth
control pill
paid $1,100 for each patient.
And a Wyeth-Ayerst study of drugs for hormone replacement in
women paid
$4,581.
While all of these payments were made to specific clinics,
the exact amounts on a single test could vary slightly by
region,
or even by clinic.
Many executives from drug or testing companies refused to
discuss
their research programs, citing confidentiality. Those who did
grant
interviews
gave consistent explanations of their payments:
They are necessary compensation for the doctors' work.
"We set up contracts that hopefully reimburse investigators
adequately for the time
they put in to screen patients,
bring them in, and provide data to us
that is as clean as possible,"
Dr. Elizabeth Stoner, the vice president for clinical research
and
contract management
at Merck Research Laboratories in Rahway, N.J., said.
Additional payments can be made, she said,
when there is "additional effort above and beyond what they
anticipated."
But doctors who are particularly successful in recruiting study
patients
and keeping down their costs can make huge profits.
"There are physicians who can net about $500,000 to $1 million a
year
doing clinical research," said Ismail Shalaby,
the chief executive of Nema Research Inc., a network of doctors
and
hospitals
in the Baltimore area performing clinical research.
"And that is not bad."
The benefits to the doctors who conduct research are not simply
financial.
Once, researchers said, the names that appeared on papers
describing drug studies were those of the actual authors.
That is no longer always the case.
Today, the coveted right to claim authorship
is often just another reward for doctors who recruit the most
patients --
even if they wrote nothing
and analyzed no data.
"They used to ask you to write," said Dr. Thierry Le Jemtel,
a cardiologist at Montefiore Medical Center in the Bronx, N.Y.,
who is a longtime academic researcher.
"Now, they send you a paper all written by a medical writer"
hired by
the drug company.
Dr. Jay Grossman, a private-practice doctor
who is an allergy and respiratory specialist with Vivra Asthma
and
Allergy Inc.
in Tucson, Ariz., said he was often a lead author on
publications
because he had been a top patient recruiter in the clinical
trials,
even though he rarely did much -- if any -- of the actual
writing.
"That's common," he said.
"It's orchestrated by the drug company's medical writer."
For example, Grossman cited a study for a SmithKline Beecham
asthma
medication
that was published in The Journal of Asthma
and another on an allergy medication sponsored by Boehringer
Ingelheim
Pharmaceutical published in The Journal of Allergy and Clinical
Immunology.
While the articles are written by a drug company writer,
Grossman said, he often suggests modifications.
As drug companies compete for top study doctors who will quickly
accrue patients,
a financial arms race has developed,
with each company seeking new ways to use cash and benefits to
spur
the research.
One practice is to offer finder's fees to doctors who are not
conducting studies
for referring patients to doctors who are.
For example, a letter from a testing company handling the
research
on a vaginal suppository for Bayer Corp. in 1996
promised "a $75 referral fee for physicians and area/federally
funded
clinics, i.e.,
Planned Parenthood, etc."
Even study coordinators -- the nurses and medical assistants
who oversee the administrative details of a study
and screen patients to see if they qualify -- are offered fees
for
finding test subjects.
In 1995, for example, Pharmaceutical Product Development Inc. of
Wilmington, N.C.,
which coordinates drug tests, needed a way to speed up
enrollment
in a study of a drug developed by Zambon Corp. in East
Rutherford, N.J.
So the company sent a fax to medical staff members
who were screening patients around the country,
offering them bonuses for fast enrollment.
"EVERY study coordinator has the chance to receive $750
just by reaching the enrollment goal of 30 evaluable patients,"
the fax said. "So GET BUSY!"
The stepped-up competition among drug companies
for the services of doctors led to the development of cash
bonuses for
them,
one of the most controversial incentives now offered.
But even companies that were uncomfortable with the idea found
it hard
to resist.
"It's a tough issue," said Dr. Cynthia Dunn, the director of the
Clinical Research Institute
at the University of Rochester and a former drug industry
executive.
"On one hand, many companies recognize it's part of what we have
to do
to be competitive.
On the other hand,
they recognize they are setting up potential conflicts of
interest" for
doctors.
Some large drug companies have refused to offer bonuses out of
ethical
concerns.
"You don't want to provide an advantage that can be
misinterpreted,"
said Dr. Joseph Camardo, the senior vice president of clinical
research
and development
for Wyeth-Ayerst Research in Radnor, Pa.
The bonuses all reward the same behavior:
enrolling patients fast.
For example, a contract last year by Ibah Inc.,
a testing company owned by Omnicare Inc.,
provided a $750 bonus for each patient enrolled by June 15
or $500 for those enrolled between June 15 and July 16 --
upping the ante for doctors whose enrollments were lagging.
Such incentives outrage some experts.
Bonuses in clinical research are "inappropriate, potentially
illegal and
certainly unethical,"
Dr. Robert Tenery, a Dallas doctor who is the chairman of the
council
on ethical and judicial affairs for the American Medical
Association,
said of such payments in general.
"Why would you get an extra $500?
How can you explain the rationale?
Maybe you took a patient who really didn't need to be enrolled."
If something goes wrong,
doctors might never be able to escape the nagging doubt that the
bonus
program
was to blame.
"How would you like to confront the family
when a family member got hurt, and you got a bonus for
enrolling?"
asked Michael Leahey, the director of the office of clinical
trials
at Columbia-Presbyterian Medical Center in New York.
A system that offers so much cash and benefits for quick
recruitment
assumes that doctors would never allow money to distort their
judgment --
in this case by causing them to put undue pressure on reluctant
patients
or to include patients who do not qualify.
But the assumption that doctors can resist financial temptations
has been proved wrong
repeatedly in other situations.
For example, throughout much of the 1980s,
doctors could refer patients to treatment centers --
such as physical or radiation therapy sites -- in which they had
a
stake.
The practice was outlawed after studies found that doctors were
overusing treatments
and tests
when they had financial interests in the centers that provided
them.
A 1992 study published in The New England Journal of Medicine
found that doctors with investments in radiation sites
prescribed such treatment as much as 60 percent more often
than those without the financial conflict.
With such studies demonstrating the effects of financial
incentives on
doctors,
experts who have studied these conflicts
said they were troubled by the emergence of research for hire.
"You have a recipe for trouble or abuse," said Marc Rodwin,
an associate professor of law and public policy at the School of
Public
and Environmental Affairs at Indiana University and the author
of a book
on financial conflicts in medicine.
"The risk is that the doctor will subconsciously downplay the
risks
or overplay the benefits"
of a particular study in order to persuade a patient to
participate.
Complicating matters,
companies sometimes fail to consider how difficult it will be to
find
patients
to meet the requirements they set for admission into a study.
Then, when recruitment falls short of expectations,
they offer to pay more to meet an unrealistic goal -- looking,
for
example,
for patients with a disease that their drug can treat
but who have no other health problems that could affect the
study.
"The simplest solution that inexperienced people think of first
is to increase the number of sites or to increase the amount of
money
you're offering,"
said Dr. Bert Spilker, the senior vice president of scientific
and
regulatory affairs
at the Pharmaceutical Research and Manufacturers of America,
the trade group for large drug companies.
"You can offer to triple the amount of money
and it will make zero difference
if the doctors are doing everything they can do.
It may be that the patients don't exist."
But,
with so much money dangling in front of them,
doctors could be tempted to bend the rules to get patients into
studies,
and could get away with it,
according to Dr. Martha Elks, an associate dean at Morehouse
School of
Medicine in Atlanta.
"Let's say you're dealing with an angina study where the
requirement for
entry
is a certain level of pain on a certain number of days of the
week,"
Elks said.
And "suppose the patient's history is not quite that but is
borderline."
Elks said she overheard two doctors talking recently about
bonuses.
One was telling the other that he would get $500
if he could sign up some patients in the next 24 hours.
"I knew this guy," Elks said.
"He is a practitioner of the highest ethics."
But, she said, "he was talking about how to massage entry
criteria."
Elks said she then noisily cleared her throat.
"I sort of a-hummed," she said, at which point the doctors
"stepped back
for a minute," suddenly realizing what one of them had been
saying.
What happened next, she said, she was not privy to know.
In 1989, Dr. Stuart Weiss was bored with private practice.
To liven up his work, the San Diego endocrinologist
tried his hand at drug studies.
It was an audacious idea --
at the time most trials were conducted by university scientists.
But Weiss worked hard to persuade a skeptical drug industry
to take a chance on someone with his background.
"I beat the bushes," he said.
"I lobbied long and hard with several organizations to give me a
shot."
Eventually, he focused on a Merck study of a new drug to treat
osteoporosis,
a degenerative bone disease.
To show his eagerness, he offered to fly to New Jersey
to meet with Merck executives at their world headquarters.
Then Weiss went further, spending his own money
to buy an expensive piece of equipment that measures bone
density.
Merck finally gave in, asking him to find 20 patients.
He came up with 40.
And there, in the entrepreneurial spirit displayed by Weiss,
lay the solution to a problem that was suddenly dogging the
pharmaceutical industry --
the slow pace of research in university laboratories.
For decades,
drug companies had been able to increase their prices almost at
will,
and thus had little incentive to develop new products.
For the comparatively small number of drugs the companies did
test,
they turned to a trusted group of medical school researchers
who dictated how trials were conducted.
And the drug companies had to wait in line:
Research financed by government grants was far more prestigious;
in the eyes of many academics, drug-company trials
were to research
what McDonald's hamburgers were to food.
In those days, researchers were reimbursed much differently than
they
are today.
Payments went to the university,
not to the investigator.
The university doctors were often paid a flat fee for their
work,
no matter how many patients they actually enrolled.
Then,
in the early 1990s, the economics of drug development changed.
Managed care
put the squeeze on drug prices, leaving companies one option:
to increase the number of drugs they were selling.
As a result,
the companies began a rush to drug development,
something that was aided by reforms at the FDA
that speeded up the approval process for new drugs.
Companies at first turned to their coterie of medical school
researchers,
but found the academic world was incapable of adapting rapidly
to the increasingly intense competition.
"We had concretized bureaucracies," Dr. David Bickers, the
chairman of
the dermatology department at Columbia University's College of
Physicians and Surgeons,
said of the academic response.
"And for companies, time is money. Companies figure that out."
Quickly,
the drug companies began recruiting a new breed of private-
practice
doctors
like Weiss, willing to mine their patient base for research
subjects.
The transformation is evident in a Times computer analysis of
thousands
of forms
submitted each year to the FDA
from doctors wanting to conduct research.
According to the analysis, 11,662 private doctors conducted drug
studies in 1997,
almost three times the number in 1990,
when 4,307 doctors conducted such studies.
And while the number of researchers and medical schools
also grew in that period, their share of the business dropped
from a third to a quarter of the total, according to the
analysis.
Private-practice doctors in research said the change was for the
better,
because the doctor was not simply tending to the patient's needs
for
the few weeks
of a study,
but often for a lifetime.
"Even though the physician may want to make money,
the moment he sits across from the patient,
he is not only responsible to himself,
he is responsible to that patient," said Dr. Norman Zinner, a
Los
Angeles doctor
who in 1994 formed Affiliated Research Centers,
an organization of private-practice urologists who conduct drug
studies.
"I have got to look you in the eye. I have got to see you
again."
Not only that, these doctors said,
but participation in research allows them to know the latest
ideas for
treatment.
"I really feel I can offer my patients more," said Grossman of
Vivra
Asthma and Allergy.
"I know more what the cutting edge is.
I know what will be the recommended therapy two years from now."
Because anyone licensed to practice medicine
is eligible to be a researcher, medical communities have been
transformed in towns
where the onslaught of managed care spawned legions of doctors
scrambling
to replace lost income.
In 1980, when clinical research was the fief of medical schools,
there were only eight projects in Tucson, Ariz.,
and all but two were at hospitals affiliated with the University
of
Arizona.
Today, researchers are scattered in offices dotting the city --
in places like the sun-baked barrios and the homely strip malls
--
conducting 157 studies in 1997 alone.
Drug studies, and with them the competition for patients,
have become as common in Tucson as the towering saguaro cactus.
Now,
with federally financed research on the wane,
it is the academic researchers who are banging on the doors of
the
drug companies,
asking for a second chance.
But they are finding it hard to keep up with the private
doctors,
who have shown themselves more willing to sign contracts
overnight,
advertise widely, offer financial incentives for patients
and open their offices at unusual times
to accommodate patient schedules.
"It's very difficult to conduct drug studies at the medical
school
because of the competition"
from private doctors, said Dr. Mark Brown, a pediatric asthma
specialist
at the University of Arizona.
"It's difficult to find patients."
To keep up with the competition from private doctors,
some academic medical centers
have recently begun setting up research divisions
to draw on their own private patients for drug studies.
But it is a fledgling effort, limited to a handful of
universities.
Still, some junior faculty members are now abandoning academia
to get into the drug-study business.
Dr. Andrew Cutler, a psychiatrist,
left the faculty at the University of Chicago to join the
Psychiatric
Institute of Florida
in Orlando, a private practice with a research business.
Then last year, he formed his own company,
Coordinated Research of Florida,
to perform drug studies full time.
Without a patient base to draw from for studies,
Cutler found other ways to recruit subjects,
including serving as a nursing home consultant.
"I will strategically pick a nursing home that has a large
population
that meets the criteria for a study," he said.
"If there is a large community practice in town,
I may work out a referral arrangement,
or make them a co-investigator,
and the arrangement is that they would be providing the
patients."
But the industry is not passively waiting for doctors to knock
on its
door.
Instead, over the last few years it has been aggressively
recruiting
doctors
with the lure of cash.
Every day, in hundreds of medical offices around the country,
blandishments arrive by fax, mail and e-mail, encouraging
doctors
to grab their piece of the research pie.
"Discover the secret for obtaining more funded studies,"
says a 1992 letter to doctors from Research Investigator's
Source,
which charges $275 to place doctors' profiles on lists of
researchers
consulted by drug companies.
A 1998 letter from Clinmark Dotcom,
an online listing service for researchers based in Irvine,
Calif.,
offered to list doctors for $350 the first year and $195 the
second.
But the letter made no secret about the reasons to join.
"Investigator grants average $43,000 per study," it said.
Then there are the ubiquitous seminars, sponsored by the
industry,
with enticing titles to attract doctors,
both fledgling and experienced in studies.
Some teach the basics, with such titles as "How to Find Clinical
Trials:
A Physician's Perspective"
and "How to Develop or Evaluate a Patient Recruitment Media
Plan."
But nothing captured the transformation of research more
than a seminar on clinical trials in Nashville, Tenn.,
sponsored in 1996 by Associates of Clinical Pharmacology, a
professional
association.
The title? "Successful Patient Recruitment: The Heart and Soul
of
Your Business."
Doctors and drug company executives milled around a racing car
parked on
the floor
of the John B. Hynes Veterans Memorial Convention Center in
Boston last
year,
waiting their turn to be photographed at the wheel.
Nearby, other images of speed dotted the exhibit hall at the
annual
meeting
of the Drug Information Association, an industry trade group.
Checkered flags appeared on corporate booths and T-shirts.
One exhibit featured a giant photograph of a cheetah;
another showed a mural of a horse race.
To some at the meeting on drug development in the global
marketplace,
the images were a perfect metaphor for the industry today:
The push to finish trials quickly and move the drugs onto the
market
has overshadowed every other goal.
"A few years ago it was 'better, faster, cheaper,' "
said M. Jane Ganter, the editor in chief of Applied Clinical
Trials,
an industry publication.
"Nobody is saying 'better' or 'cheaper' anymore.
The big emphasis is on speed."
The driving forces behind the desire for faster studies are the
industry's financial stakes.
With the clock ticking on a new drug's patent even as it is
being
tested,
every day's delay is revenue that will never be earned.
"Time is money," said James Patricelli, an analyst of the
drug-testing
industry
with Dain Rauscher Wessels. "Speed is the key."
But some in the industry worry that such singlemindedness
has led testing companies to tap an increasing number of doctors
with little or no experience in drug testing
and only a fuzzy understanding of the rules.
The Times analysis showed that during the 1990s,
70 percent of the doctors conducting human experiments
had been involved in three or fewer previous drug studies,
a number unlikely to give them mastery over the process.
A quarter of all doctors who did human experiments in 1997,
the last year for which complete data are available, conducted
only one
experiment.
"Some of the companies would be embarrassed
if they saw the quality of the people doing the research,"
said Dr. Angela Bowen, the president of the Western
Institutional Review
Board,
a private ethics board based in Olympia, Wash., that reviews
proposed
research
on human subjects. "I call them clueless."
One reason may be the predominance of generalists taking part in
the
studies.
The studies test drugs for particular diseases, like asthma,
in which a doctor's experience and specialized training are
crucial
in making assessments such as distinguishing between drug
reactions
and disease symptoms.
But doctors conducting clinical trials often have no particular
expertise
in the disease they are treating.
The Times computer analysis showed that the largest single group
of
doctors
conducting investigations was general internists;
one in five was either a general internist or a family
practitioner.
These, of course, are the doctors most Americans see for
checkups
and are thus the industry's most efficient recruiters.
But some doctors who do clinical research
say that they often are offered studies that would require them
to stretch far beyond their areas of medical expertise.
"I wouldn't do studies for hematology or neurology or lung
disease or
epilepsy,"
said Dr. Roy Fleischmann, the chief executive of Rheumatology
Research
International,
a national network of clinical research sites
that specialize in arthritis and skeletal diseases.
But, he said, "We get calls about them all the time."
Not every doctor has the power to refuse.
"There was a lot of pressure for me to do things I did not feel
comfortable doing,"
said Dr. Claudia Baldassano, a psychiatrist and neurologist
who worked for a commercial research center on the East Coast.
"They thought because I have an MD, I should be comfortable
doing all
studies."
She said, for example, that she was asked to do Pap smears
as part of a study of hormone replacement
and was asked to treat patients with diabetes.
"I said I hadn't done a Pap smear since medical school, and I
didn't
feel comfortable,"
she said.
For the diabetes study, "I said how could you expect a physician
who is
not trained"
as a diabetes specialist
to run the trials, she said.
"I was told by a vice president of operations
that I could do diabetic studies with my eyes closed."
In the end, Baldassano stood her ground on the diabetes study,
but
participated in the one on hormone replacement.
She resigned from the business after just a few months,
and now works in academic research.
Why would drug companies accept research
even from doctors who doubt their own expertise?
Because, experts said, the industry has grown so quickly
that no one has yet developed a good measurement of quality.
Drug companies are left to review two factors: speed and cost.
Systems of measurement for quality "haven't been established to
differentiate
these companies," said Patricelli of Dain Rauscher.
In an attempt to protect the quality of data and patients,
the government and industry have put into effect some means of
oversight.
The first line of defense for the integrity of the data
is the dispatch of study monitors employed by the testing
companies
to the doctors' offices to pore over the test results.
But the explosive growth of the industry has left experienced
monitors
in short supply.
As a result,
"They utilize some people who have very little experience in the
disease entity,
or the drug, or in pharmacology,"
said Fleischmann of Rheumatology Research International.
The monitors "don't understand what they are doing."
"They are looking for boxes to fill in,"
he said.
For example, he said, the most common form of arthritis,
osteoarthritis,
is also called "degenerative joint disease."
A testing company monitor who came to examine his data
announced that his patients were not qualified for the study
because she did not know the two terms meant the same thing,
he said.
"If they don't have that knowledge," Fleischmann asked,
"how can they read a chart and know what is real
and what is not real?"
Some experts said there was a decided difference between the
quality
of monitors
who work for the drug industry
and those who work for the testing companies.
Monitors sent by testing companies can be so unknowledgeable,
said Margaret Chokreff, the president of Margaret Chokreff &
Associates,
which works with a network of private doctors conducting
research in
Ohio,
that she and her nursing staff must sometimes train them about
their
own studies.
The monitors' sole task is protecting data, not patients.
That job falls largely to the patchwork system of ethics boards,
bodies that are required by federal law to approve research
proposals
involving humans.
The main responsibility of these panels
is to insure that test candidates are fully informed of the
benefits and
risks
of a particular study and that they are not coerced to
participate.
But the review boards last year
fell under criticism from government officials for reviewing too
many
studies
too quickly and for lacking expertise.
And while these boards will get involved
in deciding the appropriate language to be used for an
advertisement
for patients,
they do not consider whether patients should be told of their
doctors' financial stake.
Shimm of Porter Adventist Hospital in Denver recalled that when
he
served
on an ethics board at a university medical school,
a good deal of time was spent discussing whether payments to
patient
volunteers
were coercive.
The concern was that patients might enter studies for the money
rather than out of altruism,
the ideal that is sought.
But, immediately after such a discussion at one meeting,
another proposal came up in which a doctor stood to receive
thousands of
dollars
from the drug company for each patient recruited.
"I said, 'Wait a minute,' " Shimm said.
"If it is coercive to pay a patient $500,
why is it not coercive to pay the clinical investigator $5,000?"
But other members of the research board were not interested in
the
topic.
"I was told," Shimm said, "to sit down and shut up."
