The U.S. Department of Health and Human Services (HHS) today extended the public comment period for its new proposed requirements for human subjects research under the Common Rule. HHS’ proposal includes significant new data privacy and security obligations on research entities, including the creation of mandatory data security and information protection standards for all studies involving identifiable or potentially identifiable data, as well as potential new standards for de-identified data. HHS also proposes to categorize biospecimen research as identifiable information. HHS has extended the comment period by one month, making comments due by October 26, 2011.
