Risky AIDS
drug sent to Africa creates furor
Research was flawed and reactions were
underreported, U.S. officials say.

WASHINGTON
-- Weeks before President Bush announced a plan to protect African
babies from AIDS, top U.S. health officials were warned that research
on the key drug was flawed and may have underreported severe reactions,
including deaths, government documents show.
The 2002 warnings
about the drug, nevirapine, were serious enough to suspend testing
for more than a year, let Uganda's government know of the dangers
and prompt the drug's maker to pull its request for permission
to use the medicine to protect newborns in the United States.
But the National
Institutes of Health, the government's premier health research
agency, chose not to inform the White House as it scrambled to
keep its experts' concerns from scuttling the use of nevirapine
in Africa as a cheap solution, according to documents obtained
by The Associated Press.
"Everyone
recognized the enormity that this decision could have on the worldwide
use of nevirapine to interrupt motherbaby transmission,"
NIH's AIDS research chief, Dr. Edmund C. Tramont, reported March
14, 2002, to his boss, Anthony Fauci, director of the National
Institute of Allergy and Infectious Diseases.
The documents
show Tramont and other NIH officials dismissed the problems with
the nevirapine research in Uganda as overblown and were slow to
report safety concerns to the Food and Drug Administration.
NIH's nevirapine
research in Uganda was so riddled with sloppy record-keeping that
NIH investigators couldn't be sure from patient records which
mothers got the drug. Instead, they had to use blood samples to
confirm doses, the documents show.
Less than
a month after Bush announced a $500 million plan to push nevirapine
across Africa to slow the AIDS epidemic, the Health and Human
Services Department sent a nine-page letter to Ugandan officials
identifying violations of federal patient protection rules by
NIH's research. Africa accounts for more than two-thirds of the
world's AIDS cases, with 27 million infected.
The NIH research
"may have represented a failure to minimize risk to the subjects,"
the Office of Human Research Protections told Ugandan authorities
in summer 2002. Nevertheless, NIH officials told AP they remain
confident after re-reviewing the Uganda study and other research
that nevirapine can be used safely in single doses by African
mothers and children to prevent HIV transmissions during birth.
But they acknowledged their Uganda research failed to meet required
U.S. standards.
As a result,
NIH recently asked the National Academy of Sciences to investigate
its science in the case, and has spent millions in the last two
years improving its safety monitoring and record keeping.
"I would
say there are many lessons that we have learned from this review
that will help us do our clinical research, both domestically
and internationally, much better," said Dr. H. Clifford Lane,
NIH's No. 2 infectious disease official.
Senate Finance
Committee Chairman Charles Grassley, RIowa, has asked the Justice
Department to investigate NIH's conduct. In a letter released
Monday, Grassley said he was compelled to do so by "the serious
nature of these allegations and the grave implications if the
allegations have merit."
One lesson
already derived from a closer review of the Uganda research is
that even single doses of nevirapine can create instant resistance,
meaning patients may not be able to use the drug or others in
its class again when their AIDS worsens, Lane said.
"It was
unexpected, and what it means is nevirapine probably shouldn't
be a drug of first choice if other options are available,"
Lane said.
Lane said
NIH officials were aware in spring 2002 about the impending White
House announcement on nevirapine but did not tell presidential
aides of the problems because they were confident, even before
reviewing the Uganda research, that the underlying science was
solid.
The White
House -- though unaware of the NIH concerns -also remains confident
in Bush's $500 million plan in 2002 to send nevirapine to Africa.
Bush approved $2.9 billion for global AIDS fighting next year.
"The
president's mission is to try to stop the spread of AIDS in Africa
and to come at it from a new angle, and that is what this is all
about," spokesman Trent Duffy said.
Nevirapine
is an antiretroviral drug marketed in the United States as Viramune
that has been used since the 1990s to treat adult AIDS patients
and is known to have potentially lethal effects like liver damage
and severe rashes when taken over time.
In 1997, NIH
began studying in Uganda whether it could be given safely in single
doses to stop mother-to-baby transmissions. That research showed
it could reduce transmission in as many as half the births.
But by early
2002, an NIH auditor, the agency's medical safety experts and
the drug's maker all disclosed widespread problems about the U.S.-funded
research in Uganda.
Boehringer
Ingelheim, the Connecticut-based company that makes nevirapine,
told NIH it identified at least one "critical compliance
issue" that compromised the integrity of the study and more
than four dozen issues it described as "serious" and
"major."
Boehringer
and NIH auditors cited concerns such as failing to get patients'
consent about changes in the experiment, administering wrong doses
and delays and underreporting of "fatal and life threatening"
problems.
"It appeared
likely, in fact, that many adverse events and perhaps a significant
number of serious adverse events for both mother and infant may
not have been collected or reported in a timely manner,"
Westat Corp. reported in March 2002. Westat is a professional
medical auditing firm hired by NIH to visit and audit the Uganda
site.
Westat reported
there were 14 deaths not reported in the study database as of
early 2002 and that the top two researchers in Uganda acknowledged
"thousands" of bad reactions that weren't disclosed.
NIH said the
subsequent review whittled that list down significantly, all deaths
were eventually recorded and the majority of bad reactions are
believed to have been caused by the poor health of patients, not
the single dose of nevirapine. But they conceded it was incumbent
on a U.S. research project to fully and quickly disclose them.
Officials
said the problems began when NIH converted the research from determining
the drug's usefulness to supporting FDA approval for the drug.
Paperwork in Uganda wasn't kept to the FDA standards, they said.
"We may
not have reported exhaustively, but we reported all serious side
effects," said Professor Francis Mmiro, a lead doctor in
the Uganda study. "What you may call a serious side effect
in the U.S. is not a serious side effect in Kampala."
NIH officials
reviewed the bad news in early March 2002.
Meeting minutes,
written in shorthand, raised broad concerns: Half the babies in
the study were also enrolled in a vitamin A study that could have
affected the outcome, and medical staff running the trials didn't
follow procedures for divulging serious adverse events (SAEs).
"No mtg
minutes, no training doc(umentation), site used their own criteria
for grading SAEs. No lab normal values & serious underreporting
of SAEs," the minutes stated.
The minutes
quote an NIH official who visited Uganda as saying, "The
site staff doesn't know what they don't know."
But Tramont,
the AIDS research chief, and other top NIH officials repeatedly
dismissed the concerns as preliminary or overblown, and sought
to salvage the flawed research's underlying conclusions rather
than start over.
"There
is presently no evidence that the study's scientific results are
invalid," said a report Tramont sent to his staff less than
two weeks after getting the March 2002 Westat audit.
In January
2002, Boehringer sent NIH an early copy of its report. But the
drug maker, fearing publicity about the report might destroy its
chance to get the FDA approval of the drug for domestic use, asked
NIH to destroy it before FDA regulators could learn about it.
"Sensitive
information. Asked for it to be destroyed when audit is upon us,"
NIH official Mary Anne Luzar wrote on the cover page of Boehringer's
report.
Boehringer
says it never requested the document be destroyed, saying "our
actions throughout the study evaluation were proactive and forthcoming."

The
party was a success and was well attended by friends and
members of ImpAcTAIDS
including, Dr Gavin Strang MP.
Thanks
to our brilliant street collectors who were out all day
shaking cans and pinning red ribbons on people, we raised
a staggering £1222, that added to our raffle monies
of £1231 and donations of £136, and the evening
started off well, after the raffle (a list
of winners can be found on our web site) we had an auction
of a signed Diana Ross gold CD and a signed gold 'Batman
Returns' DVD which raised another £460, so at the
end of the night our days efforts had raised £3049,
not bad eh!
We
must thank...
