Stricter rules for clinical studies sought to protect patients
By Naomi Aoki, Globe Staff, 6/12/2002
TORONTO - Jesse Gelsinger was 18 when he volunteered to be
part of a clinical trial for gene therapy at the University
of Pennsylvania. Within hours of the treatment, his organs began
to fail, and three days later he was dead. An investigation
later revealed that the university and lead researcher in the
trial stood to gain millions from the drug being tested and
had ignored early warning signs.
The 1999 case shocked the public and the research community,
and along with a handful of other highly publicized deaths in
clinical trials, it cast grave doubt on the ability of the existing
system to protect patients. As a result, federal legislators
and regulators are considering stricter regulation of clinical
trials. And in a somewhat surprising twist, the pharmaceutical
industry - the chief sponsor of such research - also is calling
for tougher rules.
''Patients are our business,'' Heidi Wagner, head of government
affairs for California biotechnology giant Genentech Inc., said
during a panel discussion this week on protecting people in
clinical trials, at the annual meeting of the Biotechnology
Industry Organization here. ''We wouldn't be anywhere without
the patients who volunteer for these trials.''
Biotech and pharmaceutical companies depend on volunteers for
clinical studies of their drugs to prove that they are safe
and effective and to bring the drugs to market. More than 3,000
trials were taking place in Boston-area hospitals and clinics
at any given time last year. If patients lose faith in the system
meant to protect them, industry officials said, they will shy
away from clinical trials. And this is a risk the industry simply
cannot afford to take.
More than 80 percent of biotech and pharmaceutical companies
already miss their deadlines for enrolling patients, in some
cases by more than a year. And every day a trial is delayed
costs an estimated $1.3 million in direct and lost opportunity
costs, according to CenterWatch Inc., a Boston publishing company
that focuses on clinical trials.
The stakes only promise to get higher as the pace of scientific
research continues to accelerate. Since 1993, the number of
drugs in company pipelines has doubled. Innovations in technology
and the mapping of the human genome are expected to herald an
unprecedented age of discovery, meaning more drugs, more trials,
more competition for study volunteers, and more money to lose.
''In the past, we've responded when there's been a problem,''
said Dr. Greg Koski, head of the Office of Human Research Protection,
the agency that oversees all federally funded research. ''We've
got to move to a more proactive system, one that will prevent
harm, because that's what will build the public trust.''
After Jesse Gelsinger's death, the gene therapy study at Penn
was shut down. Federal investigators found that researchers
had violated their own protocol and federal safety rules, ignoring
signs seen in earlier patients that the treatment could be harmful
and failing to disclose financial conflicts. Penn set up a $1.5
million, 13-member Office of Human Research to train, assist,
and monitor researchers. The lead researcher quit in April as
head of Penn's gene-therapy institute, and the FDA has begun
a process that could bar him from human research overseen by
the agency.
Though the Gelsinger case is certainly cause for concern, Koski
and industry officials said, such cases remain the exceptions.
By and large, they said, the system does protect patients. Deaths
are rare - only about 1 in 10,000 subjects die. But the system
has become bogged down in procedural and bureaucratic complexities
that don't necessarily protect study volunteers. Koski said
the system needs to be streamlined; protections must focus on
protecting people in clinical trials rather than the institutions
running them, and on preventing lapses rather than reacting
to them.
Informed consent must go beyond getting a person's signature
on a form, said Koski, who prefers the term ''informed participation.''
Study volunteers need to understand the risks and benefits of
the clinical trial. They should be informed about the study's
goals and results from earlier trials, and be told of any developments
as the study progresses.
Koski favors a more centralized system of third-party review.
Currently, all research centers that conduct clinical trials
must have institutional review boards, or IRBs, that oversee
a study to ensure it follows standard protections established
for human research. The boards are generally made up of volunteers
from the institution.
The system leads to redundancies, especially in cases where
many different institutions are involved in a single trial,
Koski said. Rather than having IRBs from every institution review
the same study, a single IRB could oversee the entire trial.
He also supports a voluntary accreditation system for IRBs
that would encourage them to go beyond what is legally mandated
and strive for a standard of excellence. And he believes separate
boards should be established to review potential conflicts of
interest, monitor trials for any safety concerns, and watch
for any violations of protocol.
Koski's office and industry leaders disagree on relatively
few points. One key point of dissension, however, is in dealing
with financial conflicts. Genentech's Wagner supports full disclosure
of all potential conflicts - financial or otherwise - to IRB
members and study volunteers but does not believe such relationships
should automatically disqualify a researcher from participating
in a study. Koski believes there should be a presumption against
a scientist who stands to gain significantly from the success
of a drug being involved in its development.
''No matter how well intended people are, bias creeps in,''
he said.
At the panel discussion Monday, Genentech's Wagner, the sole
industry representative, was the most vocal in support of strong
federal legislation. Companies navigate an increasingly layered
system to run clinical trials, she said. The industry is regulated
primarily by the Food and Drug Administration, while many of
the academic researchers with whom the industry collaborates
on trials are regulated by Koski's office. Yet other laws regulate
the privacy of patient information in clinical trials.
Many states also have their own sets of regulations that companies
must meet. And when working with 50 different academic research
centers, Wagner said, companies are often left negotiating the
details of informed consent and study protocols with 50 different
IRBs - a task that greatly adds to the time and complexity of
managing clinical trials.
''It's adding burdens and costs to the system that don't necessarily
add to the safety of patients,'' she said.
Wagner said the industry wants one set of rules to extend to
all researchers - regardless of whether they are funded by industry
or government and regardless of the state in which they are
conducting research. She would like to see a move toward a more
centralized review process, encouraging institutions to work
with a single independent IRB that oversees and monitors large,
multisite trials.
''Strong federal legislation is the only way to get that kind
of unified system,'' Wagner said, ''because it's the only way
to preempt state law.''
Wagner believes that a bill, proposed by US Representatives
Diana DeGette, Democrat of Colorado, and Jim Greenwood, Republican
of Pennsylvania, to extend protections under federal law to
all human-research subjects would be a giant step in the right
direction. US Senator Edward M. Kennedy also is drafting a bill
to increase protections for people who volunteer for clinical
trials.
''Right now, there is growing public distrust,'' said Ken Getz,
president of CenterWatch. ''If some of the regulations
being considered are passed, it may be another way for industry
and legislators to signal that they are doing as much as they
can.''
Audits of both federally funded and industry-sponsored clinical
research have found that the most common problems are failing
to comply with study protocols, falsifying data, and failing
to properly comply with informed-consent rules. But, Getz said,
historically less than 3 percent of those cases are serious
violations that put patients at significant risk.
Nonetheless, Getz said, patients need to feel confident they
are being protected. They need to be treated as partners in
the research, rather than as subjects of study. And critical
to that endeavor is to educate people about the importance of
clinical research for medical progress as well as to be brutally
honest about the risks involved.
Although Wagner believes that streamlining clinical trials
could reduce their time and costs, Getz said other measures
may increase their cost and length, driving up prescription
drug prices. But he believes the trade-off is worth it. Better
research means better protection for volunteers in studies,
and also for the public at large because the more that is learned
in clinical trials, the better equipped regulators and physicians
are to decide whether to approve or prescribe a drug.
''At the end of the day, what matters most is the protection
of patients and study volunteers,'' Getz said. ''It benefits
all of us if research is safer and has better oversight.''

Should you enroll in a clinical trial? New book offers guidance
By Carol Cruzan Morton, Globe Correspondent, 5/14/2002
Clinical trials attract sick people seeking novel lifesaving
therapies and healthy volunteers with an altruistic desire to
help the sick. After all, clinical trials are the source of
the latest breakthrough miracles and incremental advances in
medicine - from new drugs that treat AIDS to innovative chemicals
to tame cancer.
Despite their hopes, most of the estimated 2 million sick and
healthy volunteers in clinical trials will be given drugs that
eventually flunk their tests. For one in 30 volunteers, experimental
treatments will cause serious side effects that may be fatal,
life-threatening, permanently disabling, or result in hospitalization.
Last year, for example, Ellen Roches, a healthy volunteer,
died in an asthma study under the supervision of Johns Hopkins
Medical Institutions in Baltimore. Three years ago, Jesse Gelsinger,
18, died in a gene-transfer experiment at the University of
Pennsylvania.
What you don't know about clinical trials can hurt you, say
the authors of a new book, ''Informed
Consent: The Consumer's Guide to Volunteering for Clinical Trials.''
The book comes from the Boston-based CenterWatch, which publishes
newsletters for the clinical trials industry and for volunteers
who participate as research subjects.
''In some cases, clinical trials may offer access to treatments
that can dramatically improve and extend lives of people suffering
from severe and chronic illnesses,'' write coauthors Ken Getz
and Deborah Borfitz. ''But along with promise and hope, there
are also numerous risks.''
More than 120 new remedies each year emerge from rigorous tests,
thanks to thousands of volunteers during the average 15-year
testing cycle for each drug, the authors say. Some people volunteer
in hopes of a few more years of life. Others, such as Gelsinger,
want to help scientists understand and treat others with similar
conditions. One in five drugs is ultimately approved by federal
regulators. Side effects suffered by research volunteers will
be described in the packaging material that comes with the drug
- if it makes it all the way through testing.
For some people with advanced cancer, heart disease and AIDS,
the risks of participating in a clinical trial may be better
than the worse alternative of imminent death after the failure
of inadequate but tested treatments. But healthy people also
volunteer for clinical trials that prove risky.
Two recent deaths, as well as allegations that financial conflicts
of interest have caused ethical lapses, have prompted some reforms
in agencies and institutions. Senator Edward M. Kennedy and
US Representative Diana DeGette, a Democrat from Colorado, are
circulating drafts of legislation to better inform potential
volunteers about risks, to reduce financial conflicts of interest,
to expand the scope of protection beyond federally funded research,
and to improve the institutional oversight of research trials.
Even with proposed reforms, the key safety feature in clinical
trials rests with the individual judgment of a research volunteer.
The most important principle in well-established international
standards in clinical trials is ''informed consent based on
full disclosure of potential risks and benefits,'' said former
Health and Human Services Secretary Donna Shalala.
''While everyone focuses on the deaths, it is the wrong focus,''
said Leonard Glanz, professor of health law at Boston University's
School of Public Health. ''People need to understand that research
is not treatment. Research is designed to find out if something
is a treatment. People in research projects are subjects, not
patients. They are there to benefit the research. It's not like
a doctor-patient relationship.''
Many people, however, don't see it that way. In a recent survey
of people who had volunteered for a clinical trial within the
last six months, CenterWatch found that 74 percent still knew
''little to nothing'' about the clinical trial industry, and
nearly one-third said they didn't understand all the risks.
Scientists conduct experiments on people to answer five basic
questions about new drugs or devices, say the book's authors.
Is it safe? Is it effective? Is it better than or equivalent
to other available treatments? What side effects does it produce?
What dosage works best?
Clinical trials may test different combinations of old drugs,
or they may test new ideas from a research laboratory. Human
testing begins after promising tests in animals. Some volunteers
in clinical trials may receive toxic doses of a drug. Others
may be in a comparison arm of the study that doesn't receive
the experimental drug. About 2 percent of Americans participate
in clinical research, according to the book, but the figure
jumps to 6 percent among people who have severe, chronic illnesses.
The riskiest testing happens in the first two rounds of testing,
known as phase I and phase II, where scientists are still figuring
out how much of a drug to give, what side effects it might cause,
and whether it shows any sign of doing what it's supposed to
be doing. By the third round of testing, two-thirds of the drugs
in testing have already flunked out, and scientists have some
idea about how they might work and what problems they might
cause. Phase III studies involve several hundred to several
thousand patients, or about six out of every 10 people who volunteer
for experimental treatments.
''When it comes to study risk, in particular, you may have
to dig for the full story,'' Getz and Borfitz state in their
book. ''FDA's guidelines don't require a drug's complete track
record be shared. If you want to know details, such as the number
of deaths and serious side effects observed in earlier clinical
trials, even if the study drug was not implicated, you have
to make a point to request that information.''
After his teenage son, Jesse, died, Paul Gelsinger learned
that adverse events in animals and other people were missing
from the informed consent document. His son was far from being
on the brink of death: Thanks to improved medications for his
metabolic disorder, he was asymptomatic at the time he entered
the clinical trial aimed eventually at newborns with a more
severe form of the same disorder.
As advised in the book, Gelsinger asked about financial ties
of the researcher to the company and was told that he was an
unpaid consultant. After his son's death, he learned the researcher
had a 30 percent vested interest in the company that stood to
gain the most from this research and that he received $13.5
million in stock for his share in the company. Gelsinger advocates
reform in the system and better informed consent for research
volunteers.
George Annas, professor of health law at Boston University
School of Public Health, adds another piece of advice missing
from the book.
''Your doctor should never do research on you,'' Annas said.
''The patient makes the final go, no-go decision, but they can't
make that decision unless they have reasonable information and
they understand that research is not therapy. The doctor running
the clinical trial is not working for the patient; his loyalty
is to the research protocol.''

The word on clinical trials There is widespread
public interest in taking part in clinical drug
trials, but researchers often find it hard to get
the word out to potentially interested volunteers.
Radio spots, newspaper advertisements, and television
commercials are expensive and don't always clearly
convey the message. Postings in hospitals never
seem to reach a wide enough audience.
That's why there's CenterWatch, a Website that offers
more information on trials in all of the major disease
areas than any other on-line destination. The site, based
in Boston, enables electronic visitors to research more
than 5,000 ongoing trials seeking participants. More than
80,000 individuals - patients and others - log on to the
site every month, and site coordinators expect to have
counted more than a million total visitors by year's end.
Those numbers aren't too shappy for a site that has yet
to celebrate its third birthday. Founded in June 1995,
CenterWatch has established a virtual forum through which
pharmaceutical companies, contract research organizations,
and individual investigators post trials and solicit participants
from across the country. Interested individuals can contact
the professionals directly, via email, or access telephone
numbers and mail addresses to inquire about a trial.
The site organizes information into 20 areas, from gastroenterology
to cardiology to emergency medicine. The information is
updated three times each week. Thousands of industry-sponsored
trials are conducted in the United States every year,
says Kenneth Getz, the site's publisher. "CenterWatch
views each of these trials as an opportunity for patients
to gain access to promising new techniques. [We] really
keep [our] finger on the pulse of new clinical trial developments,"
he said.
It is still free to electronic visitors, but CenterWatch
charges health professionals a low monthly rate to post
their trials. Because of this arrangement, it does not
necessarily list every trial that might interest a visitor.
Site manager Ann Kennon says the fees, even though low,
sometimes deter health professionals from organizations
with little money to establish an Internet connection
or to register online. In these cases, she adds, those
studies don't get listed.
More than 25 percent of the visitors are cancer patients,
while a significant number of others are seeking information
on diabetes, heart disease, AIDS, and skin disease. Visitors
log on from every corner of the country, Kennon says,
and nearly half of them have been recently diagnosed with
an illness.
Of the site's highpoints, perhaps the best is its e-mail
notification service. Electronic visitors can register
to receive an e-mail every time a new trial is entered
in a specified field. More than 15,000 users have joined
the e-mail notification program in the last year.
The site is also organized fairly well. There's other
information, as well: background information on clinical
research, links to other important health-related sites
and a list of new drugs approved by the Food and Drug
Administration.
On the downside, however, finding the information CenterWatch
offers can be frustrating for some users. The site lacks
a search engine; to search it, visitors must scroll through
endless pages of trial categories. And because of the
length of the trial lists, some of the topic pages are
impossible to download in a timely manner, making the
site's most useful portion difficult for visitors with
slower modems to navigate.
CenterWatch is attracting some impressive clients. For
example, the National Institutes of Health currently is
advertising for volunteers for "ALLHAT," a study on treatment
of hypertension. Kennon says two of her goals for next
year are to make the site more accessible for patients
and cheaper for professionals to list trials. She expects
to have a site redesign by the end of the year.
