An institutional review board (IRB), also known as an independent ethics committee (IEC), ethical review board (ERB), or research ethics board (REB), is a type of committee used in research in the United States that has been formally designated to approve, monitor, and review biomedical and behavioral research involving humans.
An exception to the currently approved protocol is a planned temporary variance that has received IRB approval prior to its initiation, e.g., enrollment of subject who does not meet eligibility criteria or accommodation of a subject who moves out of the area for the remainder of his/her participation in the research.
