OVERSIGHT OF NIH AND FDA: BIOETHICS AND THE ADEQUACY OF INFORMED CONSENT

THURSDAY, MAY 8, 1997

HOUSE OF REPRESENTATIVES,

SUBCOMMITTEE ON HUMAN RESOURCES,

COMMITTEE ON GOVERNMENT REFORM AND OVERSIGHT,

Washington, DC.

The subcommittee met, pursuant to notice, at 10:05 a.m., in room 2247, Rayburn House Office Building, Hon. Christopher Shays (chairman of the subcommittee) presiding.

Present: Representatives Shays, Snowbarger, Pappas, Towns, and Kucinich.

Staff present: Lawrence J. Halloran, staff director and counsel; Anne Marie Finley, professional staff member; R. Jared Carpenter, clerk; and Cherri Branson, minority counsel.

Mr. SHAYS. I call this hearing to order. Next week the President will formally apologize to the survivors of the 40-year Tuskegee experiment, a federally funded study in which black men were allowed to suffer and die of a curable disease-syphilis-in the name of scientific research. Last week, this subcommittee heard testimony from Gulf war veterans ordered to take a potentially toxic drug for an experimental use without being informed of any possible side effects.

The road from Tuskegee to Baghdad is lined with other landmarks of scientific arrogance and human tragedy. Thalidomide, radiation experiments, the EZ measles vaccine trials-those notorious lapses in the protection of human research subjects and the complex ethical implications of emerging biomedical issues like cloning, gene therapies, and AIDS vaccine trials compel us to ask: How effective are current mechanisms to review ethical issues and detect violations of informed consent requirements?

What needs to be done so patient protections keep pace with scientific advances? Do we need a permanent national panel to serve as the arbiter of biomedical ethics issues? Physicians have a moral duty to inform human research subjects of the foreseeable risks of participation, and a duty to minimize those risks. The discipline of bioethics has evolved from the Hippocratic oath to the Nuremberg Code to current national and international standards to protect the health and human dignity of all who submit themselves to help advance scientific knowledge.

But the current system of bioethics review appears to be showing signs of age and disrepair. Multiple layers of review and enforcement provide a false sense of security that difficult issues are being confronted. The regulatory scheme lacks specific provisions to pro

By one recent estimate, more than half the federally funded research projects inspected by the FDA between 1977 and 1995 failed in some way to inform research subjects fully of the experimental nature of the medical procedure. Multi-site research studies further challenge the capacity of local IRBS to control the research nominally under their purview. The National Institutes of HealthNIH are charged with the potentially conflicting duties to fund research, conduct research, and enforce bioethics regulations. As a result, the NIH Office of Protection for Research Risks-the OPRRfaces both institutional barriers and logistic obstacles in attempting to police thousands of research projects.

The third leg of what is supposed to be the national bioethics triad doesn't even exist. Department of Health and Human Services-HHS-regulations call for a permanent ethics advisory board the EAB-to advise the Secretary of bioethics issues.

The latest, the National Bioethics Advisory Commission-the NBAC was directed in 1995 to make their first priority protection of the rights and welfare of human research subjects. Only recently staffed, the commission has now been directed by the President to focus their attention on cloning, and will not review ethical issues arising from specific research projects.

Missing are the periodic evaluations and external oversight needed to maintain a rigorous bioethical review system. We begin our part of that external oversight today. And we look to our witnesses for suggestions to improve patient protections and informed consent procedures. At this time I would recognize the ranking member and an equal partner in this effort, Mr. Towns.

[blocks in formation]

Next week the President will formally apologize to the survivors of the 40-year Tuskegee Experiment, a federally funded study in which black men were allowed to suffer and die of a curable disease - syphilis - in the name of scientific research. Last week, this subcommittee heard testimony from Gulf War veterans ordered to take a potentially toxic drug for an experimental use without being informed of any possible side effects. The road from Tuskegee to Baghdad is lined with other landmarks of scientific arrogance and human tragedy -thalidomide, radiation experiments, the EZ measles vaccine trials.

Those notorious lapses in the protection of human research subjects, and the complex ethical implications of emerging biomedical issues like cloning, gene therapies and AIDS vaccine trials, compel us to ask:

How effective are current mechanisms to review ethical issues and detect violations of
informed consent requirements?

What needs to be done so patient protections keep pace with scientific advances?
Do we need a permanent national panel to serve as the arbiter of biomedical ethics issues?

Physicians have a moral duty to inform human research subjects of the foreseeable risks of participation, and a duty to minimize those risks. The discipline of bioethics has evolved from the Hippocratic Oath, to the Nuremburg Code, to current national and international standards to protect the health and human dignity of all who submit themselves to help advance scientific knowledge.
