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

By JOHN SOLOMON
The Associated Press

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."
