The Harsh Reality Of Clinical
Trials
Shows Another Case of The Double Standard For Medical Marijuana.
The Context For "Research." -- 2 Articles
(Marijuananews note: There is no mention of
medical marijuana in this story even though it ran in the midst of the recent debate. As
this story makes very clear, when the IOM talks about warning patients -- ["One
possible approach is to treat patients as n-of-1 clinical trials, in which patients are
fully informed of their status as experimental subjects using a harmful drug delivery
system, and in which their condition is closely monitored and documented under medical
supervision, thereby increasing the knowledge base of the risks and benefits of marijuana
use under such conditions."] it is applying a much higher standard than that
used on pharmaceutical products. Ironically, this heightened concern for safety is shown
for a drug with no lethal dose. However, as these reports
make clear, "The purpose of doing research is to produce knowledge, not to produce
a benefit for the individual." The proposed research on medical marijuana, while
far more solicitous of the safety of the subjects, is really not aimed at benefiting those
who need it most.
In this context, it is very important to understand that the only
people who will be used as subjects in testing medical marijuana will be those for whom
nothing else works. That is another difference between testing medical marijuana and the
tests described here.)

Clinical Trials

N E W Y O R K, May 6 Each year, hundreds of thousands of Americans enroll in
clinical trials. No one knows the exact number because there is no one is keeping track.
No one in government or industry is keeping track of how many people are killed or
injured taking part in these experiments.
"Theres more protection offered animals in research than humans," says Dr.
Eric Cassell of Cornell Medical College. "But the reason is, while that seems
shocking, the reason is we expect humans to be able to protect themselves."
But there is evidence thats often not the case and that some studies expose people
to risks they never accepted.
The problem can be flagrant. In 1998, a survey of 394 academic and medical institutions
found that 9 percent had suspended a research project because no patient consent was ever
obtained. Then theres the subtler problem of the consent document itself. Forms can
be 11 pages long and are often crammed with unfamiliar terms.
"They describe it in the language of medicine or the language of science and you
wouldnt have the foggiest idea of what they were talking about," says Cassell.
Often the patient turns for advice to those running the experiment. But researchers want
to enroll volunteers, not scare them away.
Individual Benefit Not Priority
"The process of describing whats going on is slanted
toward emphasizing the benefits and minimizing the risks," says Professor Alexander
Capron of the University of Southern California.
Whats also often "minimized" is just what it means to go from patient to
research subject, and how, instead of having access to treatments that have been proven
effective, a person is limited to that one treatment being tested.
"The purpose of doing research is to produce knowledge, not
to produce a benefit for the individual," says Capron.
Review boards at medical centers across the country are supposed to
oversee these studies and make sure patients know just what theyre getting into. But
there are now so many studies that some boards are becoming overwhelmed, often leaving
patients to fend for themselves.

FDA Moves to Reduce Accidental Drug Deaths
Health: Agency to unveil strategy today to prevent fatalities blamed on misuse of
prescriptions.
By MARLENE CIMONS, Times Staff Writer
WASHINGTONMore than 100,000 Americans are inadvertently
killed every year by prescription drugsone of the leading causes of death in the
country.

Pharmaceutical Reactions Major Cause of Death; Marijuana Does Not Kill But Must Be
Approved By FDA?

The Lancet
Reports That Deaths From Medication Errors More Than Double In Decade
Some people die of drug reactions that are completely unexpected, the stuff of dramatic
headlines and heavy lawsuits.
But the majority of such deaths are preventable, the result of
mistakes or confusion about dosage, dangerous drug interactions from mixing medications or
known allergic reactions. Some patients, especially the elderly, die because their liver
or kidneys are so weakened by other illnesses that they cannot effectively process new
drugs.
Alarmed by such drug-induced fatalities, the Food and Drug Administration is talking
with leading drug companies, the American Medical Assn., hospitals and consumer groups
seeking waystogether and individuallyto further protect patients.
In a 150-page document expected to be released today, the FDA plans to unveil some of
its initiatives. These include an upgraded computer network that will allow drug companies
to report unexpected adverse reactions quickly and a new approach to language about the
known side effects of prescription drugs that will give patients and doctors better and
clearer warnings.
The actions were prompted in part by a study published in the Journal of the American
Medical Assn. last year that concluded that adverse drug reactions are among the top six
causes of death in the United States.
But other factors also propelled the issue to the top of the FDAs agenda. Under
pressure from patients and politicians for faster access to promising medications, the FDA
has in recent years moved drugs more rapidly through the regulatory pipeline. Such speed
raises the risk once a drug is in widespread use.
Over the last two years, the FDA has recalled five drugs and moved to reevaluate
several others, including the diabetes drug Rezulin, whose problems were detailed in a
Times series last year, and the Parkinsons medication Tasmar, both of which have
caused instances of liver failure. Whether Rezulin will remain on the market is still
under debate.
"More can be done" overall to enhance public safety, said FDA Commissioner
Jane E. Henney, who shortly after being confirmed by the Senate in October created a task
force to study the drug approval process. She predicted in an interview that the effect of
the changes "will be tremendous."
Some of the changes are underway, and others are in the talking stages.
Among them:
- An $8-million computer upgrade that will enlist the nations 13 leading drug
companies to immediately report any sudden and unexpected reactions to recently licensed
drugs. This replaces a computer index that was linked to a paper-based file that was
cumbersome and slowed the agencys ability to respond quickly, said Dr. Janet
Woodcock, director of the FDAs center for drug evaluation and research.
The new system means the "FDA can learn about trends faster and act on them
faster," Woodcock said.
- An international agreement among U.S. drug regulators and those in Europe and Japan to
use the same terminology to describe drug reactions or causes of death so that global
trends can be more clearly and rapidly identified. "Since companies are now marketing
around the world, adopting these [standardized terms is] a major undertaking,"
Woodcock said. For all nations to use the same language "gives us the best chance
possible to find something and spot a trend."
- Revised drug information for physicians that will highlight
precautions about drugs in an easier-to-find format so doctors dont have to search
through pages of detailed information to find what they need to know about possible drug
reactions. The FDA plans to propose this within a year.
The drug industry has expressed some concerns about the changes,
fearing that industry liability could increase as a result of doctors missing something
important.
"I dont think its possible to condense all the key information on
prescription drugs into such a simplified, standardized format," said Marjorie
Powell, assistant general counsel for the Pharmaceutical Research and Manufacturers of
America, an industry trade group. "It raises lots of things that a creative
plaintiffs lawyer could argue in court."
But Nancy Ostrove, an FDA official involved in drafting the labeling overhaul,
countered: "Their concern is that by highlighting certain information it will
discourage prescribers from reading the rest. We dont believe that, because we think
they arent reading it now."
Nor are doctors always talking about it with their patients. Many feel hampered by the
managed care climate, which has shortened the time they spend with their patients. Also,
many physicians, traditionally trained to stick to a few drugs for any particular
condition, now are forced by certain health plans to use specific drugs, some of which
they may not be familiar with.
"If you ask physicians whether they talk to their patients
about all the side effects and problems associated with drugs, [most] will say they go
through all of it," said one AMA official who requested anonymity. "The reality
is that about [two-thirds] engage in some type of oral communication about the drugs, and
when you get into the specifics of side effects, its more like 30%."
- New information for consumers. Up to 10 new products annuallythose deemed by the
FDA to have the riskiest side effectswill carry new, easy-to-understand warning
information for the patients themselves. Currently, only certain categories of products,
such as hormone replacement therapy or drugs with extremely dangerous side effects such as
thalidomide, contain such information. "We believe that the more educated consumers
are, the safer they are going to be," Woodcock said.
However, many experts acknowledge that it is tough to get consumers to pay
attentioneither to labels or to their own doctors. The FDA is looking for more ways
to encourage consumers to become more involved in their own health. The agency already
sponsors community education outreach programs for women through its womens health
office and would like to expand these programs "if we could find the resources to do
it," Woodcock said.
- Better coordination, including the increased use of computers, to avoid medication
errors arising from confusion over similar brand names. Problems occurred recently, for
example, over prescribing practices for the new pain reliever Celebrex, close in name to
the antidepressant Celexa, as well as the epilepsy drug Cerebyx.
"We have the ability to forbid a name thats too similarwe do turn down
namesbut we cant always do as close a review as we like," Woodcock said.
"We need computers to do name comparisons in advance."
- Designated hospitals to monitor and report drug reactions. The program would be modeled
on an existing pilot project that watches for adverse reactions to heart valves, implants
and other medical devices.
The FDA stresses that tackling adverse drug reactions is not something it can do alone.
The agencys primary responsibility is ensuring that a drug is safe and effective
before it reaches the market, and it has the authority to remove a drug from circulation
if it proves dangerous. But it cannot regulate how doctors practice medicine, how
pharmacists fill prescriptions or what consumers do once the drug reaches their medicine
cabinet.
Dr. Nancy Dickey, president of the AMA, believes that the problems need to be addressed
by everyone in the system, with novel ways to protect consumersmuch like surgeons
and hospitals seeking to avoid mistakes by putting ink on a patients body at the
site where the operation is to occur.
"We are looking for that equivalent for prescription drugsa change in the
entire systemthat could help prevent mistakes," she said.
FDA officials agree. "A lot of these deaths are preventable," Woodcock said.
The agencys report and its ongoing discussions with outside groups, such as the
pharmaceutical industry and the AMA, takes "the first step toward trying to reduce
those deathsbecause we think it can be done."
