It was disturbing to read recently that
Genentech decided to increase the price
of Avastin (bevacizumab), a biopharmaceutical
product used to treat colon cancer,
to $100,000 per year. Avastin has no
competitors, allowing Genentech to set
the price at whatever the market will
bear. As the cost of this medicine
increases for patients, so will the cost to
insurers, health care programs such as
Medicare and Medicaid, and the health
care system in general.
The recent approval by the FDA of
Sandoz's Omnitrope human growth hormone
represented a significant first step
in bringing more affordable biopharmaceuticals
to the US marketplace. This
decision clearly demonstrates that
sound science exists to support the
approval of generic biopharmaceuticals
despite assertions from special interests
to the contrary. It demonstrates that
generic companies can develop safe and
effective biopharmaceutical products. It
demonstrates that the FDA already has
the authority to approve such products.
And it brings our nation one step closer
to the day when generic versions of
expensive biopharmaceuticals will be
readily available.
Scientific support for generic biopharmaceuticals
was further bolstered
in May 2005 with the publication of the
US Pharmacopeia's (USP) monograph
that addresses product-quality standards
for somatropin, a human growth
hormone. By publishing this monograph,
the USP indicated that a biopharmaceutical
product could be characterized
and standards established,
despite the brand sector's claims to
the contrary.
Recent actions in Australia and the
European Union (EU) further confirmed
the science and safety of generic biopharmaceuticals.
Already, generic
human growth hormone has been on
the market for nearly a year in
Australia, and the EU approved the
same medicine in April 2006. Both
Australia and the EU have approval
processes in place for generic biopharmaceuticals.
By contrast, the United
States is far behind.
GPhA strongly believes that it is possible,
under the FDA's current structure,
to permit approvals and marketing
of a vast array of generic biopharmaceuticals
with relatively low to modest
complexity, and to expand that system
in the coming years to permit the
approval of more complex products as
sound science evolves. The FDA
approval of Omnitrope supports our
position.
For several years, the FDA has
pledged to address the approval process
through the release of a white paper
along with draft guidances on policy,
chemistry, manufacturing and controls,
and immunogenicity. To date, no action
has been taken. Members of Congress
have noticed the delay. Sen Orrin Hatch
(R, Utah) and Rep Henry Waxman (D,
Calif) inquired why these documents, as
well as the review of an application for
a generic human growth hormone,
were stalled for about 3 years. The FDA
responded to their inquiry by stating
that the agency is now considering the
development of broader guidance documents,
even though it had flatly
rejected this approach years earlier on
the grounds of lack of industry value. It
appears that these documents are
being delayed for political reasons, not
scientific ones.
The use of biotech medicines is
increasing, and marketed biologic
products are growing at a rate of 17%
annually, with no signs of slowing.
Already, biopharmaceuticals comprise
a growing percentage of Medicare and
Medicaid costs. Members of Congress
have recognized the problem of burgeoning
costs, with one senator noting
that, "if we don't explore prudent steps
to encouraging generic biologics, drug
prices may rise so much that it would
endanger Medicare itself."
It is time for Congress to ensure that
the FDA will take those prudent steps.
The FDA should not be denying US citizensand the health care systemsimilar
savings through the approval of
generic biopharmaceuticals.
