CLINICAL MEDICINE:
FDA to Release Data on Gene Therapy Trials
Jocelyn Kaiser
Moving to allay public concerns over the
risks of gene therapy experiments, the U.S.
Food and Drug Administration (FDA) last week
proposed publicly releasing much of the safety
and protocol data from clinical trials that
it now keeps confidential. The agency wants
to apply the same policy to animal-to-human
transplants, another controversial experimental
procedure.
Several gene therapy researchers praised
the decision. "We think public fears
should be assuaged, and one way to do it
is to make the information available,"
says Inder Verma of the Salk Institute for
Biological Studies in La Jolla, California,
president of the American Society of Gene
Therapy. Phil Noguchi, director of the cellular
and gene therapy division at FDA's Center
for Biologics Evaluation and Research, agrees
that the proposed rules are important symbols:
"It's the perception of something being
hidden that's the scary part." Biotech
industry officials, however, are not pleased;
they worry that releasing clinical data could
stifle drug development and that the public
may misinterpret the safety reports.
The changes come in response to the 1999
death of 18-year-old Jesse Gelsinger in a
gene therapy trial at the University of Pennsylvania
in Philadelphia. The incident triggered a
flurry of reports and congressional hearings
on whether safety problems from this and
other trials were being fully disclosed by
sponsors, whether academic or commercial
(Science, 12 May 2000, p. 951). It also revealed the confusion over current
government reporting requirements.
Under the proposed rule, FDA would make public
much of the information that sponsors now
submit in confidence to the agency on their
gene therapy clinical trials, including preclinical
toxicity data, protocols, informed consent
forms, ongoing reports of adverse events,
and records of any FDA investigations. Under
FDA rules, for example, companies must report
within 7 to 15 days serious events that are
unexpected and possibly related to the therapy.
Companies themselves would remove personal
and confidential business information from
these documents, which FDA would then post
on the Internet.
The Biotechnology Industry Organization (BIO)
says the FDA proposal sets a "troubling
precedent" by carving out an exception
to its confidentiality policy. BIO officials
are concerned that confidential patient and
business data may inadvertently be released.
What's more, says BIO bioethics counsel Michael
Werner, releasing data on all adverse events
before they can be investigated could "be
misleading or misunderstood or taken out
of context" by patients and the public,
as many of these problems are related to
a patient's underlying disease and not the
therapy. But Noguchi disagrees, noting that
the only events that sponsors have to report
immediately are those possibly related to
treatment; the rest are summarized in an
annual report.
Federal officials say this new body of information
will "complement" the work of the
Recombinant DNA Advisory Committee (RAC),
which advises the director of the National
Institutes of Health (NIH) on the ethics
and safety of gene therapy trials. The RAC
already releases protocols and safety reports
on NIH-funded trials (www4.od.nih.gov/oba/rdna.htm). (Those few investigators with no direct
or indirect NIH funding can submit information
voluntarily to the RAC but would be obliged
to follow the FDA rule.) The RAC now wants
to analyze those adverse event reports for
trends and recently proposed establishing
a new working group to do so. Amy Patterson
of the NIH Office of Biotechnology Activities,
which runs the RAC, explains that the FDA
proposal will satisfy the public's desire
for access to safety information right away,
while the RAC will continue to provide an
open forum for analyzing the reports.
The rules also cover the rapidly evolving
field of animal organ and tissue transplants.
FDA plans to release data from such xenotransplantation
trials, while the Department of Health and
Human Services (HHS) is finalizing more stringent
guidelines for trials as part of a broader
effort to reduce the risk of introducing
new viruses into the population (Science,
30 January 1998, p. 648). A new HHS xenotransplant advisory committee--similar
to the RAC--will hold its first meeting in
late February.
