When federal drug regulators approve a medicine for sale, they limit how drug makers sell it. A drug approved to treat only breast cancer cannot be marketed for lung cancer even if some studies suggest that the medicine may save lung patients.
But the Food and Drug Administration proposed guidelines Friday that would change this, and advocates on both sides of the issue say that lives are at stake.
The
rules would allow drug and device makers to provide doctors with copies
of medical journal articles that discuss product uses that have not
been vetted or approved by the F.D.A. The rules also say that drug
companies do not have to promise to adequately test the unapproved use
discussed in the article.
Advocates of the rule say the F.D.A.
is so slow in assessing drug and device benefits that companies need to
be able to hand out medical journal articles so that doctors can learn
immediately about life-saving uses.
“The consequence of rapid
disclosure of these benefits could be measured in lives,” said Dr.
Scott Gottlieb, a former F.D.A. deputy commissioner.
Ken Johnson, senior vice president for the Pharmaceutical Research
and Manufacturers of America, said that “journal articles can offer
physicians valuable insight that helps them make informed decisions
regarding appropriate medical treatments for their patients.”
But
critics of the proposal say that drug and device companies have a long
history of promoting unapproved drug and device uses that later proved
dangerous and that allowing companies to talk about such unapproved
uses removes incentives for companies to research adequately whether
the new use is actually beneficial.

“People will die if they are getting drugs that don’t have clear
evidence that the benefits outweigh the risks,” said Dr. Sidney Wolfe,
director of Public Citizen’s health research group.
Representative
Henry Waxman, Democrat of California, said the proposed rule “caters to
the industry’s desire to market their products without adequate testing
or review.”
The F.D.A. will accept comments from the public on the proposal and take it up for final consideration in 60 days.
The
reason for this debate is that doctors are not overseen by the F.D.A.
Medicine is regulated by state medical boards, which generally let
doctors prescribe drugs and devices as they see fit regardless of
F.D.A. judgments.
In some cases, this is beneficial.
Pediatricians for years had very few drugs approved for their use
because drug makers often failed to test new medicines in children. So
they prescribed drugs for children anyway, and, sometimes, saved lives.
A 2006 study estimated that more than 20 percent of all prescriptions written by doctors were for unapproved uses.
But
drug makers have in the past abused doctors’ discretion by telling them
that some medicines were appropriate for patients in whom the drugs may
have caused more harm than good. In 2004, Pfizer paid a $430 million fine to resolve criminal and civil charges that it marketed its epilepsy drug Neurontin for conditions in which the company’s own studies suggested that the drug was ineffective.
The
F.D.A. has for years struggled to find the appropriate balance between
the need to inform doctors of experimental but hopeful drug and device
uses and the need to guard against hucksters promoting dangerous
products as cure-alls.
To complicate the issue, the drug agency’s
power to prevent companies from providing truthful, albeit uncertain,
information to doctors has been questioned by federal courts as a
possible infringement of commercial free-speech rights.
Congress
stepped in to resolve the issue in 1997, passing a law that let drug
makers hand out studies from medical journals as long as reprints were
given to the F.D.A. beforehand and they promised to seek approval from
the agency of the use discussed.
That law lapsed in 2006 and
“questions have been raised since then about what our policy is,” said
Rita Chappelle, an F.D.A. spokeswoman.
Under the proposed rule,
the agency would let drug and device companies pass out articles to
doctors if the articles were peer-reviewed and came from a journal with
an expert editorial board. The article must be accompanied by a
prominent warning that the use described is not approved or cleared by
the F.D.A.
The agency abandoned the requirement that drug and
device makers must provide the studies to the F.D.A. beforehand or
promise to seek approval of the discussed use. An F.D.A. official said
the agency did not really enforce those requirements anyway.
Diane
Edquist Dorman, vice president of the National Organization for Rare
Disorders, said she supported the F.D.A. position because patients with
rare diseases are generally treated with unapproved drug uses about
which doctors must be informed.
“And these companies are just
never going to do the confirmatory trials when only a couple of hundred
people have the disease,” she said.
But Dr. Steven Nissen,
chairman of the department of cardiovascular medicine at the Cleveland
Clinic, said the rule would stop companies from underwriting expensive
trials to confirm new drug uses. “Companies could openly promote
products for unapproved indications without testing these drugs,” he
said. “I’m astonished that this rule would even be considered.”
