The first step in the evolution of ethics is a sense of solidarity with other human eings.

1998 Pediatric Rule passed by Congress, stipulating that new drugs for children must include specific pediatric labeling information
2000 Further publicized ethical abuses prompting establishment of the Office of Human Research Protections (OHRP)
Belmont ReportBelmont Report
National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research
3 basic principles for research
Belmont ReportBelmont Report
Respect for persons, or an individual’s autonomy-
elements of the informed consent requiring that: Information necessary to make a decision must
be presented that is,the risks and benefits, if any, of participation.
The information must be presented at a level that can be understood by the patient or study subject.
Participation must be voluntary.

“has demonstrated a pattern of misrepresenting the danger of various military exposures that continues today”

What studies are being done now under the guise of counter terrorism, hidden from the public by the “Patriot Act?”
Vulnerable Populations-Children
Pint-size people vs. real dataPint-size people vs. real data 10 drugs most commonly prescribed for
children that lacked pediatric labeling—drugs were prescribed more than 5 million times
HIV studies in foster children Too vulnerable? vs denying access to Too vulnerable? vs denying access to

one-fourth of the U.S. population is made up of “people of color” Only 5% of trial participants

evidence) Nigerian Pfizer meningitis trial =>
resistance to polio vacciination
Politics of Research: Race and Gender Overlap
1980 and 1983, fully one-fifth of contraceptive research was conducted in developing countries
Oral contraceptive research in Puerto Rico Adverse events analysis was inadequate
Quinacrine The effect of power inequities between men
and women Lack of social support for many women Coercion by medical providers or government
agencies

Almost all the women were Almost all the women were low income, poorly educated women of color in developing countries.
Respect for Persons, autonomy, self-determination No explanation of experimental nature of
quinacrine and no informed consent or offer of alternatives
Shifting ResearchShifting Research to Developing Countries to Developing Countries
United States accounts for ~ 4 percent of the world’s population vs. 84% for dev. Countries
90 percent of $ is spent on the illnesses of the wealthiest countries,
leaving 10 % of monies to care for 84 % of the global population
Vulnerable international populations
• Limited economic development• Inadequate protection of human rights• Inadequate community and cultural
experience with, or understanding of, scientific research
• Limited availability of healthcare and treatment options
• Limited ability of individuals in the community to provide informed consent due to illiteracy and language, educational, or cultural barriers

it is based on a valid scientific purpose for using a lesser standard, provides social benefits for the local host community, and shows a favorable risk-benefit ratio for the individual research participants
