PSORIATIC
ARTHRITIS MEDICAL NEWS
Recently,
there's been a great deal of publicity about medications. Some of
it is good news and some of it isn't. For many of us with Psoriatic Arthritis
and other related diseases, it becomes difficult to determine which of
the
many medicines offered, become the medications we, along with our doctors,
decide to try. These are difficult decisions and the more we understand
about
them, the better our choices can hopefully turn out to be.
STUDIES
FIND ARTHRITIS DRUGS WORK FOR PSORIASIS
By DEENA BEASLEY - Reuters -LOS ANGELES (Feb. 22) -
Biologic drugs used to treat rheumatoid arthritis are also effective against
psoriasis, an incurable disease that leads to thick, scaly patches of
skin,
according to new research.
The
drugs -- Immunex Corp.'s Enbrel and Johnson & Johnson's Remicade --
are
bioengineered antibodies designed to inactivate proteins linked to
inflammation. In clinical trials to be presented next week at a meeting
of
the American Academy of Dermatology in New Orleans, both drugs reduced
symptoms of moderate to severe psoriasis in about half of patients, Enbrel
after being injected twice weekly for six months and Remicade six months
after three initial infusions.
''The
results are socko (impressive),'' said Dr. Alice Gottlieb, professor of
medicine at the Robert Wood Johnson Medical School in New Brunswick, New
Jersey, and the presenter of the studies. ''A 75 percent drop ... means
these
people are wearing shorts and swimsuits and feeling good about themselves.''
Psoriasis,
a chronic disease affecting more than seven million Americans,
occurs when skin grows faster than normal and old skin is not shed quickly
enough, causing inflamed, swollen and scaly patches. Drugs now most commonly
used to treat psoriasis --cyclosporine or methotrexate, can lead to kidney
or
liver damage with repeated use.
Since
psoriasis strikes many people when they are young adults, it is seen as
a lucrative market for biotech firms that could potentially sell their
drugs
to patients for decades. Like rheumatoid arthritis, psoriasis seems to
be a
disorder in which a person's immune cells attack his own body.
A
mid-stage trial of 112 patients, injected twice a week for six months
with
either Enbrel or placebo, found that 56 percent of patients treated with
Enbrel had at least a 75 percent improvement in their psoriasis at the
six-month point compared with 5 percent of patients on placebo. Thirty
percent of Enbrel patients achieved the trial's primary goal of a 75 percent
improvement at three months.
DRUGS BEING USED ''OFF LABEL'' - Enbrel was approved by the U.S. Food
and
Drug Administration last month as the first treatment for psoriatic
arthritis, a disease that involves joints and skin. Gottlieb said side
effects seen most frequently in the Enbrel trial were mild upper respiratory
infections. She noted that the Enbrel trial was not designed to look at
how
long the disease remissions would last and additional studies of both
drugs
are needed.
A
29-patient trial of Johnson & Johnson's Remicade, which is given
intravenously, found that about half the psoriasis patients given three
infusions of the drug over six weeks maintained a 75 percent improvement
in
symptoms six months after treatment.
The
Remicade trial was an extension of an earlier study showing that 73
percent to 82 percent, depending on dose levels, of patients saw a 75
percent
symptom improvement 10 weeks after they were given the three infusions.
Immunex
has said it plans to eventually file for U.S. Food and Drug
Administration (FDA) approval of Enbrel for treatment of psoriasis, but
the
drug is already being used ''off-label'' for that purpose. ''I have already
written 15 prescriptions for Enbrel for my psoriasis patients,'' Gottlieb
said.
Several
other companies are also developing biologic drugs for psoriasis.
Biogen Inc. filed last year for U.S. and European approval of its
experimental psoriasis drug, Amevive, which is designed to selectively
target
a subset of T-cells. The drug can be given by injection or intravenously.
Amevive induces long-lived remissions, but two sets of doses are needed
to
get to a 50 percent response level, Gottlieb said.
Genentech
Inc. has said it plans to file a marketing application with the FDA
this summer for Xanelim, an antibody designed to block certain immune
cells
from entering and binding to skin tissue. Once Xanelim, which is
self-administered subcutaneously, is out of a patient's system, relapse
occurs, so patients would need ''a once-a-week bolus pretty much forever,''
the researcher said. Reut15:16 02-22-02 Copyright 2002 Reuters Limited.

WIDELY
USED ARTHRITIS PILLS MAY BE NEW TREATMENT FOR CANCER April 4, 2002 -
BOSTON (AP) -- Scientists are hard at work recycling Celebrex and Vioxx,
the
red-hot inflammation pills taken by tens of millions for arthritis. They
have
an unlikely new use in mind, one maybe even more important than soothing
throbbing joints.
Their goal: Prove these medicines prevent cancer and perhaps even help
cure
it.
While
there are good scientific reasons to think they are onto something, the
experiments to settle it are not finished, and the optimists could be
dead
wrong. Nevertheless, cancer researchers and pharmaceutical executives
entertain fantasies of a breakthrough role for an off-the-shelf medicine.
Among
them is Dr. Philip Needleman, who has spent more than a decade - first
at Washington University and now at Pharmacia, where he is research director
- developing Celebrex as an arthritis medicine. Just three years on the
market, it is the 10th biggest selling prescription drug in the United
States.
But
in his vision, that success is a mere warm-up. "People ask what gets
me
juiced," Needleman says. "It's the possibility that in five
or 10 years,
someone will say, 'Oh yes. Celebrex. That's also used in arthritis."'
Many
in industry, government and medical schools seem to share his daydream.
In a world where people are used to disappointment, hopes run high that
Celebrex and its rivals can be redirected against the most feared disease
of
all.
The
drugs block production of a chemical called COX-2, which triggers pain
and inflammation and may also fuel the growth of cancer, where it is often
found in abundance.
The
first big test will be in preventing colon cancer, second only to lung
cancer as a killer. Three big studies involving about 6,000 volunteers
will
see if Celebrex and Vioxx stop pre-cancerous growths in the colon. The
results should be known within two years.
"If
we could reduce the incidence of this disease by half, what an incredible
contribution that would be," muses Dr. Monica Bertagnolli of Brigham
and
Women's Hospital in Boston, director of one of the studies. "That's
what is
driving all of this."
But
that might be just the start. Experiments on lab animals strongly suggest
the arthritis drugs could also help cure cancer, especially if combined
with
chemotherapy or radiation. Whether the approach will actually work is
unclear, since testing Celebrex on cancer patients has just begun, but
many
research teams are joining in.
In
fact, Dr. Andrew Dannenberg, director of cancer prevention at Cornell's
Weill Medical College, estimates there may be as many as 100 separate
cancer
studies involving these drugs worldwide.
"When
in the history of drug development has a drug moved from arthritis to
cancer prevention and then been fast-tracked into cancer therapy?"
he says.
"It's completely unprecedented."
One
of these studies will examine whether Celebrex shows any sign of warding
off lung cancer in 20-year, pack-a-day smokers. Many others are testing
the
drugs in people with cancer of the breast, lung, esophagus, skin, prostate
and bladder.
One
reason for doctors' willingness to try the drugs is their apparent
safety. Celebrex and Vioxx - known as COX-2 inhibitors - were designed
to be
easier on the stomach than aspirin and other inflammation fighters. Their
lack of frequent side effects makes them unique in cancer, a field not
known
for gentle therapies.
"Everyone
is looking to integrate COX-2 inhibitors into every aspect of
cancer treatment, because we don't expect them to be toxic," says
Dr. Adam
Dicker of Jefferson Medical College in Philadelphia.
A
major sponsor of this research is the National Cancer Institute, which
oversees Bertagnolli's colon cancer prevention study plus many of the
smaller
treatment experiments with Celebrex.
Dr.
Ernest Hawk, the agency's chief of gastrointestinal research, says the
government is betting on the drug because of the overlapping lines of
evidence - from epidemiology, animal experiments and more - that the approach
should work.
"What
stands out is the weight of the evidence," Hawk says. "I can't
think of
any class of drugs that have this much going for them, especially in colon
cancer. It's the consistency of the story."
Some
of the most intriguing evidence comes from big population studies. At
least 25 of them involving about 2 million people have examined whether
colon
cancer is less common in people who take aspirin, which works similarly
to
the new arthritis drugs. Together they suggest that regular users are
about
40 percent less likely than expected to have precancerous polyps or to
die
from colon cancer.
Results
of the first carefully controlled experiment of aspirin in colon
cancer will be made public at a cancer conference in April. Dr. John Baron
of
Dartmouth Medical School said it will show aspirin in fact does slow the
return of precancerous polyps after their removal, although the benefit
is
modest.
"There
may be a tendency for people to hope for a magic bullet and not get
it," Baron cautions. Nevertheless, "the idea that aspirin is
effective opens
the door for the COX-2 agents," which are safer and may be more powerful,
too, as experiments on lab animals seem to show.
Celebrex
is already approved to help block polyp formation in people with a
rare genetic condition who develop tens of thousands of polyps and invariably
get colon cancer by their 40s. Bertagnolli's study and two others, sponsored
by Merck, Pharmacia and Pfizer, will settle whether the drugs can do the
same
for garden-variety polyps.
Some
believe Baron's results are a strong hint they can, although the
researchers hope for a more powerful effect than Baron saw with aspirin.
In
the end, they say, aspirin may turn out to be the best choice for people
at
risk of both heart attacks and colon cancer; the COX-2 blockers may make
more
sense for those worried solely about cancer.
Still,
safety is likely to be a concern for the new drugs, too, since even
rare side effects could outweigh the benefits when taken lifelong by large
numbers of healthy people at average risk of cancer.
Aspirin,
ibuprofen and similar nonsteroidal anti-inflammatory drugs shut off
production of prostaglandins, substances that cause inflammation but also
have benefits. They do this by interfering with an enzyme called
cyclooxygenase, or COX, which the body needs to make prostaglandins.
In
the late 1980s, Needleman and others found there actually are two
varieties of COX: COX-1 promotes normal body functions, making blood clot
and
protecting the lining of the stomach. COX-2 comes into play in response
to
injury and illness and causes pain and inflammation.
The
discovery led to the design of drugs that stop inflammation in a more
precise way - by blocking only COX-2 rather than both kinds of COX, as
aspirin does. The result is medicines that relieve arthritis while having
little effect, either good or bad, on the heart or the stomach.
An
inkling that the same drugs might also ward off cancer emerged from rat
and mouse experiments in the 1990s. In one, scientists looked for a way
to
change the fate of mutant rodents that typically grow 600 colon polyps.
When
they knocked out the gene that makes COX-2, they found the animals' polyp
counts fell to 90.
In
another, they grew mice that make vastly elevated amounts of COX-2 in
their mammary glands. The result: They got cancer.
In
tumor-prone animals, Celebrex and Vioxx can suppress or prevent cancer
of
the colon, prostate, intestines, breast, skin, lungs, bladder and tongue.
Many other anti-inflammatory drugs can do this, too, but the COX-2 blockers
seem to be the most potent, at least in animal experiments.
Translating
such discoveries into treatments for people is always tricky. But
scientists say there is plenty of circumstantial evidence that COX-2 does
bad
things in humans, as well. For instance, levels of the enzyme are unusually
high in some pre-malignant growths, such as colon polyps, as well as in
many
kinds of cancer.
Scientists
are trying to learn exactly why, but they believe the process
probably starts harmlessly enough. The body makes COX-2 as a normal response
to injury but sometimes doesn't know when to stop.
"In
those cells that go on to become cancers, the ability to turn off
production of COX-2 may be lost," says Dr. Steven Dubinett, UCLA's
chief of
lung cancer research.
Scientists
theorize too much COX-2 may help cancers flourish in several ways:
It promotes the growth of new blood vessels, which tumors need for
nourishment. It makes them less likely to die on cue, as ordinary cells
do
when they become hurt or defective. And it protects the tumor from the
usual
surveillance of the immune system.
By
using drugs like Celebrex to turn down COX-2 production, scientists
believe they may take away one of cancer's shields, making it more prone
to
killing by chemotherapy and radiation treatment.
"Often
new drugs have surprising effects not initially anticipated, and they
may be good or bad," says Dartmouth's Baron. "This whole story
illustrates
this perfectly." Copyright 2002 The Associated Press. All rights

RHEUMATOID
DRUG MAY PROLONG LIFE April 5, 2002 LONDON (AP) -- Methotrexate, a
key drug for rheumatoid arthritis, could help people with the crippling
disease live longer, new research suggests.
Methotrexate,
originally a cancer drug, has been used to fight rheumatoid
arthritis for about 15 years. Since then it has been proven to slow
progression of the inflammatory disease and to make patients feel better,
but
a new study provides the first hint it may also save lives.
Experts
said the study, published this week in The Lancet medical journal,
were encouraging but did not provide definitive proof. Rheumatoid arthritis
strikes about 1 percent of people, usually in middle age.
People
with the disease tend to die about 10 years sooner than normal,
according to Dr. Theodore Pincus, a prominent rheumatoid arthritis researcher
from Vanderbilt University in Nashville, Tenn.
It
is not the type of arthritis common in the elderly because of the
wear-and-tear of aging. It occurs when the immune system goes awry and
attacks the joints, causing severe inflammation in the lining of the joints,
pain and stiffness. It is also linked to an increased risk of heart disease.
Scientists
believe people with rheumatoid arthritis have shorter life spans
partly because they face increased chances of getting heart disease and
dying
from it.
The
latest study, led by Dr. Frederick Wolfe of the Arthritis Research Center
Foundation at the University of Kansas School of Medicine, found that
patients on methotrexate were 60 percent less likely to die prematurely
than
those not getting the drug.
They
were 70 percent less likely than people not on the drug to die from
heart disease.
Experts
said that finding bolsters the growing body of evidence that
inflammation might play a role in heart attacks and that anti-inflammatory
medication might ward them off.
Methotrexate
works by switching off the underlying inflammation caused by the
immune response.
Dr.
David Scott, professor of clinical rheumatology at Guy's, King's and St.
Thomas' Medical School in London, said the survival findings echo what
doctors have suspected.
"If
you go back 20 years when people had little treatment for their
rheumatoid arthritis, they did very badly. Death was common," said
Scott, who
was not connected with the research. "There's no doubt that nowadays
it seems
a lot better, inasmuch as not so many people seem to be dying and patients
seem to be doing a lot better overall."
The
biggest change in the last decade in rheumatoid arthritis has been the
widespread use of methotrexate, he said.
"This
would seem to be a drug treatment effect, but you can never be certain
that it isn't that the disease is getting milder," he said.
Part
of the uncertainty comes from the way the study was conducted, other
experts said.
It
involved 1,240 people with rheumatoid arthritis seen at a specialist
arthritis center between January 1981 and December 1999. A total of 588
of
the patients were put on methotrexate, at their doctors' discretion. Those
more ill tended to get the drug. By the end of the study, 191 of the patients
had died, 72 of whom were on methotrexate.
Wolfe
adjusted his statistics to take account of the fact that the
methotrexate group was sicker, but experts say the study's method could
not
rule out that factors other than methotrexate could have been at work.
A
more robust approach is to randomly assign patients to either methotrexate
or a dummy pill so that not even the doctors know who's had what.
"He's
adjusted for all the confounders that he can think of," said Dr.
Marc
Hochberg, head of rheumatology and clinical immunology at the University
of
Maryland School of Medicine. "But you still wouldn't be comfortable
concluding, based on this one study, that methotrexate is the reason that
the
patients have a lower mortality rate."
Hochberg
noted that studies designed similarly to this one had shown that
estrogen therapy was linked with a lower risk of heart disease death in
post-menopausal women, but that when researchers finally tested the idea
by
randomly giving estrogen and dummy medication, no death prevention was
apparent. Copyright 2002 The Associated Press.

VIOXX
AND MENINGITIS A popular painkiller may have a rare but serious side
effect. A U.S. Food and Drug Administration report published in the Archives
of Internal Medicine links the non-steroidal anti- inflammatory drug Vioxx
to
a non-infectious form of meningitis. Five cases of aseptic meningitis
in
people aged 16 to 67 have been investigated and linked to Vioxx use, the
FDA
says. None of the cases were fatal. The FDA is requiring that meningitis
be
added to the list of potential side effects of the drug, Symptoms of
meningitis include, headache, stiff neck, eye pain, fever and chills,

OSTEOPOROSIS
DRUG EVISTA NOW BEING PROMOTED FOR HEART DISEASE
The osteoporosis drug Evista (raloxifene) does not seem to increase the
risk
of heart attack and other heart problems in women with cardiovascular
disease. In fact, raloxifene may offer some protection to women with
cardiovascular disease or who are at high risk.
Raloxifene
was designed to battle osteoporosis by boosting bone density.
Overall, raloxifene did not affect the risk of heart attack, heart-related
chest pain called unstable angina and other so-called coronary events.
Nor
did the drug affect the overall risk of stroke or mini-stroke.
But
among women at high risk of cardiovascular disease, those taking
raloxifene had a 40% lower risk of heart attack, stroke and other events.

INFORMATION ON EVISTA FROM UNIVERSITY OF ILLINOIS
SCHOOL OF PUBLIC HEALTH by Dr. Samuel Epstein MD
There is a confusion with Evista. Most people think of it as an estrogen
substitute. It is not meant to be an estrogen substitute, and it's not
being
marketed as such.
It
is being marketed as an alternative to women who cannot take estrogen,
who
would like to prevent osteoporosis.
The
drug's manufacturer, Lilly, with FDA's complicity, has suppressed
critical information that this drug poses major risks of ovarian cancer.
In
a study specifically designed by Lilly to prove the drug's safety, Evista
was shown to induce ovarian cancer in both mice and rats. Moreover,
carcinogenic effects were noted at dosages extending below the therapeutic.
However,
the study concluded: "The clinical relevance of these tumor findings
is not known." Lilly reached this conclusion despite the scientific
consensus
that the induction of cancer in well-designed studies in two species creates
the strong presumption of human risk.
Nevertheless,
Lilly failed to disclose this critical information in its
"Warning" to women. Furthermore, no reference at all is made
to these risks
in a Lilly-sponsored publication on Evista in the December 4, 1997 issue
of
the New England Journal of Medicine.
Ovarian
cancer is recognized as an uncommon complication of long-term hormone
replacement therapy in the post-menopausal. Ovarian cancer strikes about
24,000 U.S. women every year, accounting for 4% of all their cancers.
About
15,000 women die from ovarian cancer annually, making it the most lethal
female reproductive cancer.
Lilly's
suppression of the evidence of ovarian cancer risks from Evista is as
reckless as is FDA's marketing approval, conduct which merits congressional
and legal scrutiny.
This
drug should be withdrawn from the world market immediately. As
importantly, a 'Cancer Alert' should be sent to the over 12,000 women
who
have participated in U.S. and international clinical trials in the absence
of
informed consent. These women should also be offered lifelong bi-annual
surveillance for the early detection of ovarian cancer at Eli Lilly's
expense."

ARTHRITIS
DRUG MAY CAUSE LIVER DAMAGE
March 29, 2002 WASHINGTON (AP) -- A prescription drug for rheumatoid
arthritis has been linked to dozens of serious liver injuries and 12 deaths
and should be banned, a consumer advocacy group told the government Thursday.
Arava began selling in 1998 as a competitor to the gold-standard treatment
for rheumatoid arthritis, called methotrexate. When the Food and Drug
Administration approved Arava, the agency noted Arava worked no better
than
the older drug, but said patients needed some different options.
Since
then, the FDA has received at least 130 reports of severe liver
toxicity linked to Arava use, including 56 hospitalizations and 12 deaths,
said Dr. Sidney Wolfe of the consumer advocacy group Public Citizen.
Two
of the deaths were people in their 20s.
Since
Arava and methotrexate work equally well, and methotrexate also bears
a
warning about possible liver damage, Wolfe compared the two. The FDA has
six
times more reports of liver damage among Arava users than methotrexate
users
- even though thousands more people use methotrexate, he said.
Citing
similar reactions abroad, the European Union last year warned patients
and doctors about Arava's toxicity, Wolfe said. He wants the FDA to go
further and ban Arava's sales.
The
FDA said it would carefully consider Wolfe's petition.
A
spokeswoman for Arava manufacturer Aventis Pharma said she had not seen
the
petition and declined comment about liver damage. Lise Geduldig said Arava
was "an important therapeutic option" taken by 200,000 people.
The
American College of Rheumatology last summer warned doctors to take
special care in prescribing Arava, by repeatedly testing patients' livers
for
signs of harm.
But
it is impossible to predict which patients will be at risk, said Dr.
David Yocum of Arizona Health Sciences Center, who recently had an Arava
patient die. Yocum is a former scientific adviser to the FDA who joined
Wolfe's call for a ban.
Unlike
other drugs that can clear the body shortly after patients swallow a
dose, Arava can takes months to dissipate. Yocum said that means there
is not
much doctors can do if a patient shows signs of trouble.
Yet
some insurance companies pay only for Arava, not more expensive newer
therapies that do not come with the same risks, Yocum complained.
"I
do not believe that the general rheumatologist understands or has any
knowledge about these serious and potentially life-threatening
complications," he said.
Rheumatoid
arthritis affects about 2 million Americans, the vast majority of
them women. It is not the kind of arthritis that plagues the elderly as
their
joints essentially wear out. Instead, the immune system goes awry and
attacks
patients' own cartilage. It typically strikes between ages 25 and 50.
Liver
damage is not the only Arava concern, Wolfe said. FDA records show more
reports of lymphoma, high blood pressure and a life-threatening autoimmune
disorder called Stevens-Johnson syndrome among Arava users compared with
methotrexate, he said. Copyright 2002 The Associated Press. All rights

AUTOIMMUNE
DISEASE MORE LIKELY WITH ENDOMETRIOSIS
By Kathleen Doheny - SAN DIEGO, Feb 26 (Reuters Health) - Women with
endometriosis, in which tissue normally found inside the uterus begins
to
grow elsewhere in the body, are more likely than women without the condition
to suffer from autoimmune diseases such as rheumatoid arthritis or lupus,
according to survey findings presented here Monday.
The
researchers found that women with endometriosis were also more likely
to
have asthma and allergies, to have abnormally low thyroid function and
to
have either chronic fatigue syndrome or fibromyalgia, National Institutes
of
Health research fellow Ninet Sinaii reported at the VIII World Congress
on
Endometriosis, sponsored by the American Society for Reproductive Medicine.
"While
other studies have shown there may be some autoimmune dysregulation in
women with endometriosis, this is probably the first population-based,
epidemiological study" to look at the issue, Sinaii said.
Sinaii
and colleagues from the NIH and George Washington University in
Washington, DC, polled 3,680 women with surgically diagnosed endometriosis,
asking them if they had ever been diagnosed with an autoimmune disorder,
an
endocrine disorder, allergies, asthma, chronic fatigue syndrome or
fibromyalgia. The women ranged in age from 14 to 89, and their average
age
was about 36.
"The
thing that gives this study statistical power is the sample size,"
Sinaii noted. "Our hypothesis was, if so many studies have shown
autoimmune
dysregulation (in women with endometriosis), it makes sense that we would
also see other autoimmune diseases."
The
team speculated that the fibromyalgia and chronic fatigue they found
among the survey respondents might be related to the pain caused by
endometriosis. More than 98% of the women surveyed reported pelvic pain,
and
41% reported infertility.
The
results: 12% of the women surveyed also had an autoimmune disorder such
as lupus or multiple sclerosis, while less than 2% of women in the general
population have either disease. And 42% of the women with endometriosis
had
underactive thyroid glands, versus less than 5% of women in the general
population. Asthma affected 12% of the women with endometriosis, but strikes
only 5% of women overall. Sixty-one percent of the endometriosis patients
suffered from allergies, versus 18% of women overall.
Chronic
fatigue syndrome and fibromyalgia, though not considered autoimmune
diseases, were also more common among women with endometriosis; 31% had
either condition, while 4% of women overall have fibromyalgia and less
than
1% have chronic fatigue syndrome.
More
than 5 million women in the US and Canada have endometriosis, according
to the Endometriosis Association, a Milwaukee-based nonprofit research
and
education organization that supported the research. When the tissue begins
growing outside its normal site, for example along the fallopian tubes,
there
can be chronic pelvic pain, disabling menstrual periods, pain during sex,
and
infertility. Treatments include surgery, hormones and pain medicines.

FDA
SUSPENDS DRUG-TESTING ROLE March 19, 2002 WASHINGTON (AP) - The Food and
Drug Administration is suspending a rule that lets the government require
safety testing of adult medicines commonly given to children - from asthma
treatments to Prozac.
The
reason: FDA says Congress recently reauthorized financial incentives for
manufacturers to do those studies. The FDA said it wants to see if the
new
law makes the old mandate, which drug makers hated, unnecessary.
But
three Democrats complained to President Bush on Monday that the action
was halting "an important regulation that protects children from
potentially
unsafe and improperly dosed medications."
Adult
medications are commonly given to children without studies of their
safety or proper dosing because doctors have no alternative.
Drug
makers have used the financial incentives to focus their studies on more
expensive drugs, like Prozac, rather than cheaper ones that no longer
have
patent protection, but are used as much if not more in children, wrote
Reps.
Henry Waxman of California, John Dingell of Michigan and Sherrod Brown
of
Ohio.
The
FDA's so-called "pediatric rule" was adopted in 1998. A conservative
think tank and the Association of American Physicians and Surgeons
immediately filed suit against it, represented by an attorney recently
appointed to be the FDA's chief counsel. He reportedly has recused himself
from the government's debate of the issue.
Shortly
after the pediatric rule's adoption, Congress passed the financial
incentives, so it's unclear to what extent the FDA ever forced manufacturers
into child drug studies.
The
new Best Pharmaceuticals for Children Act, signed into law in January,
reauthorized the financial incentives, plus set up a grant program to
allow
taxpayer dollars for pediatric studies of drugs their makers, despite
the
incentives, won't do. During a two-year suspension of the older mandate,
the
FDA will assess if the new law takes care of the problem, said spokeswoman
Susan Cruzan.
But
the new law is "no substitute for requiring drug makers to perform
safety
studies," said Waxman spokeswoman Karen Lightfoot. Copyright 2002
