The Common Rule is a 1991 rule of ethics in the United States regarding biomedical and behavioral research involving human subjects. A significant revision became effective July 2018. It governed Institutional Review Boards for oversight of human research and followed the 1975 revision of the Declaration of Helsinki; it is encapsulated in the 1991 revision to the U.S. Department of Health and Human Services Title 45 CFR 46 (Public Welfare) Subparts A, B, C and D. Subpart A. The Common Rule is the baseline standard of ethics by which any government-funded research in the US is held; nearly all U.S. academic institutions hold their researchers to these statements of rights regardless of funding.
