Drug trials under scrutiny
People suffering from life-threatening
diseases turn to experimental treatments, which can carry special risks

After removal of Lynn Gasorowski's
breast and lymph nodes failed to rid her of cancer, doctors wanted to continue
attacking the disease aggressively.
Albany oncologist Dr. Michael Kolodziej
Gasorowski participate in an experimental study in which she would receive
three drugs not usually taken together. She would get four treatments in under
four months, half the time of the standard regimen.
Gasorowski agreed to give it a
try. But after the third treatment, she was weak, incoherent and dehydrated.
"I'm saying, 'This is it, let me die,' " Gasorowski recalled.
Kolodziej told her that she could
back out of the study, though he encouraged her to keep going. She did.
Four years later, the 46-year-old
Colonie woman remains cancer-free and a believer of clinical drug trials --
experimental studies in which patients take new, unapproved medicines or new
combinations of approved medicines. But as companies try to push more drugs
to market, the studies have come under increased scrutiny after a series of
mishaps.
Last month, the news broke that
federal authorities were investigating whether two former researchers at Stratton
Veterans Affairs Medical Center Hospital in Albany improperly enrolled patients
in drug trials they weren't eligible for. The researchers, Dr. James Holland
of Voorheesville and Paul H. Kornak of Clifton Park, could face manslaughter
charges if found responsible for speeding as many as five patients' deaths.
This comes after the Institute
of Medicine in Washington, D.C., last fall recommended broader federal oversight
of research involving patients. The report was commissioned after the death
of an 18-year-old during a gene-therapy study at the University at Pennsylvania.
In 2001, the prestigious Johns Hopkins University in Baltimore was ordered
to halt research on patients temporarily after the death of a healthy 24-year-old
woman in an asthma study.
The Albany case has sparked a federal
review of research throughout the entire VA medical system, especially because
Kornak had his medical license revoked in three states before being hired
at the VA.
Still, local researchers and hospital
managers outside the VA said the situation should not stop people from participating
in drug trials. The studies aid the development of cures for deadly and debilitating
diseases and can provide patients access to effective drugs years before they're
on the market.
"Any rogue investigator could
bypass the informed consent process and recruit patients" who didn't
belong in the study, said Lee Van Voris, chief medical officer at St. Peter's
Hospital in Albany.
Consumer advocates and an attorney
representing the families of deceased drug trial participants agreed that
Kornak's background makes the Albany case unusual. But they said a more common
problem may have contributed -- lax oversight. They cautioned people to evaluate
risks carefully before jumping in.
The problem, said Philadelphia
attorney Alan Milstein, was that oversight bodies "failed in monitoring
and supervising what was going on and ultimately in protecting the human subjects."
Milstein has filed a class-action
lawsuit against Kornak and Holland, claiming the researchers violated well-established
medical standards and patients rights.
Hundreds of people in the Capital
Region currently are in studies to test drugs. St. Peter's, Albany Medical
Center, Ellis Hospital and Glens Falls Hospital offer studies, as do some
doctors' offices.
To participate in drug trials,
patients must meet strict medical criteria. They also must be informed of
risks and be allowed to back out at any time.
No one involved in the investigation
of Holland and Kornak has offered a possible motive for their alleged falsification
of patient records to enroll study participants.
In general, experts said financial
incentives can tempt researchers to seek more patients for their studies.
Depending on the source, drug companies can pay researchers $1,000 to $2,500
per patient enrolled in a trial.
"The money is enormous, and
it is poisoning the process," Milstein said.
Local researchers dispute the claim
that study work is especially lucrative. They offer drug trials mainly, they
said, because the studies provide treatments patients could not otherwise
get.
"I look at clinical trials
as doing the ultimate right thing for our patients," Kolodziej said.
"There are not oncology practices getting rich on clinical research."
At Albany Medical Center, which
participates in about 100 drug studies annually, clinical trials contracts
brought in $6.5 million last year, said Dr. Vincent Verdile, dean of the center's
medical college. But those contracts just covered the institution's costs,
including researchers' salaries and medical tests for participants.
"It's an absolute wash,"
Verdile said.
Researchers who work at hospitals
or universities have no direct financial incentive to enroll patients because
the institution receives the fees.
Still, for the institution, a base
of research can attract grant dollars and lure talented scientists, Verdile
said. And bringing money to an institution helps a researcher's career, said
John Kaplan, a professor at Albany Med's Center for Medical Ethics, Education
and Research.
"Any given person working
in an institution is better off if they bring in money than if not, generally,"
Kaplan said.
At the Stratton VA, Holland and
Kornak's patients were terminally ill with cancer. Some, like Donald J. Lifgren
of Schenevus, faced few treatment options.
"When somebody thinks they're
going to die, they'll grasp at any straw to stay alive," said his widow,
Nancy R. Lifgren.
Because patients with limited options
can easily be swayed, drug trials can present ethical questions even with
the most sincere researchers, said Arthur Levin of the New York City-based
Center for Medical Consumers.
"The more vulnerable the patient
population, the more care there has to be that as little coercion or no coercion
occurs, that people are making these choices in a considered way and not being
railroaded with false hope, which the researcher may honestly believe,"
Levin said.
At Stratton, the VA's Office of
Research Compliance and Assessment was charged with monitoring the drug studies.
Hospitals where research is done also have internal oversight panels, called
institutional review boards.
Members of boards at other hospitals
said they are compulsive about overseeing research at their institutions and
were surprised to read reports that it took the VA's oversight bodies nearly
a year to halt studies after a drug company noticed discrepancies in records.
"Any institutional review
board worth its salt is going to find out about that pretty quickly,"
Van Voris said.
VA officials have repeatedly declined
comment on their research programs since the federal probe was disclosed.
The IOM's fall report stated the
internal review boards have become overburdened with the rise in number of
drug trials. The report called for the formation of participant protection
programs to take over some of their functions.
Still, drug studies are not inherently
bad -- just risky, Levin said. What's important is that participants have
all the relevant data to make sound decisions, he said.
"If you're very sick and nothing
is working, you may be willing to take more risk," Levin said.
After her husband's experience
at Stratton, there's nothing that would get Lifgren into a drug trial. "I
don't trust them now," she said.
Barbara Waring, on the other hand,
will likely continue to participate. The 58-year-old Duanesburg resident was
diagnosed in 1995 with Parkinson's disease, a progressive movement disorder
marked by tremors.
She got involved in her first drug
trial with Dr. Stewart Factor of Albany Med in 1996 and ended up on a drug
that helped her symptoms. She participated in a second study that required
lots of blood tests, but had no direct benefit to her.
What she wants, she said, is to
help find treatments for Parkinson's that will allow patients to live better
with the disease early on -- when they can still enjoy themselves.
"I feel like somebody has
to do these," she said.
EVALUATE FACTORS:
The decision to participate in
a drug trial comes down to evaluating a number of factors:
How sick are you?
Are there other treatments for
your disease that are working?
What's the prognosis for your illness?
That is, how long do you have to live if you don't try a new treatment?
How likely is it that the treatment
will work, based on previous studies?
What phase is the drug development
in? Phase II trials usually are done on healthy people to test the safety
of a drug and side effects are less predictable. Phase III trials involve
patients with diseases the drug is intended to treat, and there is more research
to base expectations on.
Are your questions to the doctor
and institution being answered promptly and honestly?
