•Voluntary consent of the
human subject is absolutely
essential
•Favorable risk/benefit ratio
•Research must help society
•Research should be based on
previous knowledge
21. •Participant must be free to
stop at any time
•Research should not cause
mental & physical suffering
•Research should avoid risk of
injury & death
22.
23. Declaration of Helsinki (1964)
•Well being of subject >
interest of science & society
•Consent should be in writing
•Limited use of placebo
•Greater access to benefit
29. Common Rule (1981)

•Minimal risk
30. •Sets forth requirements for
•IRB membership
•Review procedures
•Criteria for approval
•Lists requirements for

56. Never ending debate
•Whether the "greater good"
trumps the rights of the
individual?
•Are individual’s rights what
make up the greater good?
•Is it the greater good that
allows for individual’s rights?
57. Take Home Message
•"If it wasn't documented, it
wasn't done.”
•GCP is more than a piece of
paper or a set of rules
•A mind-set of dedication that
ensures a high level of ethics
& quality in research
