FDA Says
OMB Risk Assessment Bulletin Hampers Drug Safety
Alerts
FDA Week
May 22, 2006
FDA is raising
major objections to the Office of Management and Budget's
proposed risk
assessment standards, saying they could block FDA from
warning doctors and
the public about side effects of marketed drugs and
would make it difficult
to help the public during a pandemic flu. FDA is
under political pressure to
let the public know earlier about potential
dangers of approved products, and
OMB's draft guidelines would make it
nearly impossible to do so, says FDA
drug center chief Steve Galson.
But a critic of FDA’s position
says the data-quality law exempts agency
decisions during a public emergency
such as deadly flu outbreak.
At issue is a “risk assessment bulletin”
released by OMB in January that
aims to improve how federal agencies assess
risk when developing
policies. The bulletin helps implement the Data Quality
Act (DQA). The
National Academy of Sciences is peer reviewing the document,
and Monday
(May 22) an NAS panel heard what various agencies had to say about
it.
FDA will submit detailed comments later.
Representatives from
FDA, the National Institutes of Health and the
Centers for Disease Control
and Prevention all complained that the
bulletin is too broad to implement
because of both timing and financial
constraints.
FDA reviewed 109
alerts it issued last year -- including public health
advisories, a
drug information page, and doctor and patient information
sheets --
that yielded nearly 200 documents. Of those, 92 documents
would have been
defined as risk assessments by the bulletin, which means
FDA could not have
released them, and 28 were borderline.
Galson said it is difficult to
determine if a product on the market is
to blame for adverse event reports
FDA receives, but the agency may want
to let doctors and patients know about
potential problems with a product
anyway. The public sends FDA thousands of
e-mails a day asking about
adverse events.
“They don't want to wait
for us to do that complex risk assessment,” he
said, adding that the real
risk assessment is often made in the doctor’s
office based on information
available to the doctor and patient.
“The public health interest may be
to tell the public about an adverse
event before a dose-response relationship
can be defined.”
Industry has said in the past that FDA's drug safety
plans would violate
the Data Quality Act. FDA is proposing a “Drug Watch” Web
site as a key
part of changing how the agency ensures the safety of drugs
post-market.
Under the plan, a drug safety board made up of members from FDA
and
other agencies is supposed to review emerging safety data and
decide
what goes on the Drug Watch Web site. But Galson said in December
that
FDA was going “back to the drawing board” on the Web site
after
receiving a flood of negative comments from drug companies.
Some
lawmakers, and patient and consumer advocates began pushing for
drug safety
changes after a string of bad press on certain
antidepressants, which now
carry a warning of increased suicidal
ideation in adolescents; Cox-2
inhibitors such as Vioxx, which was
pulled from the market over fears the
drug causes heart attacks; and the
acne drug Accutane, which is strictly
regulated using a registry.
Galson named these events as prime examples
of public health advisories
FDA could not have made under the proposed
bulletin.
“This is something FDA put out information on before the full
risks were
known,” he said.
The bulletin also would hinder FDA in
alerting the public to potential
communicable diseases, Galson
said.
“A new communicable disease comes up and we have to put out
some
information about a test that is used to diagnose it or a vaccine, it
is
very difficult to put it in context,” he said. “It would
be
inappropriate in fact to put it in context because sometimes there
isn't
a comparison. The comparison is no treatment at all.”
Galson
said other routine administrative procedures such as classifying
medical
devices, also would be difficult if the agency were required to
first fully
assess risk.
It is difficult to make rules for the entire government to
follow,
Galson added. Those pushing the standards were in large part
interested
in risk assessment standards used by the Environmental
Protection
Agency, and those stakeholders have not contacted FDA, Galson
said.
Bruce Levinson with the Center for Regulatory Effectiveness, which
was
the primary force behind the DQA, said public emergencies are
exempted
from the law so Galson's pandemic flu example does not apply. As
for
telling the public about adverse events, FDA can make adverse event
data
public, but it should not put its own spin on it without
properly
assessing risk, he said. If FDA is worried about a product based
on
adverse event reports, Levinson said the agency should have criteria
for
determining when it meets that threshold.-- John Wilkerson
