The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars
engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their
use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has
a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J. Cicerone
is president of the National Academy of Sciences.
The National Academy of Engineering was established in 1964, under the charter of the National Academy of
Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the
selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal
government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national
needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Charles M.
Vest is president of the National Academy of Engineering.
The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of
eminent members of appropriate professions in the examination of policy matters pertaining to the health of the
public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional
charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care,
research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine.
The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad
community of science and technology with the Academy’s purposes of furthering knowledge and advising the
federal government. Functioning in accordance with general policies determined by the Academy, the Council has
become the principal operating agency of both the National Academy of Sciences and the National Academy of
Engineering in providing services to the government, the public, and the scientific and engineering communities.
The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr.
Charles M. Vest are chair and vice chair, respectively, of the National Research Council.

Dear Dr. Hamburg,
In April 2010, the US Food and Drug Administration (FDA) asked the Institute of
Medicine (IOM) to respond to five questions about ethical and scientific issues in studying the
safety of approved drugs. FDA requested a final report on the five questions in 2011. In light of
the scheduling of a joint meeting of FDA’s Endocrinologic and Metabolic Drugs Advisory
Committee and Drug Safety and Risk Management Advisory Committee on July 13–14, 2010,
FDA further requested a letter report addressing question 1 of the charge—“What are the ethical
and informed consent issues that must be considered when designing randomized clinical trials
to evaluate potential safety risks?”—by July 2010. The attached letter report, which has been
reviewed in accordance with IOM review procedures, addresses that question.
Sincerely,
Ruth R. Faden
