IRB (Institutional Review Board)

What is IRB?

An institutional review board (IRB), also known as an independent ethics committee (IEC) or ethical review board (ERB), is a committee that has been formally designated to approve, monitor, and review biomedical and behavioral research involving humans with the aim to protect the rights and welfare of the research subjects. In the United States, the Food and Drug Administration (FDA) and Department of Health and Human Services (specifically Office for Human Research Protections) regulations have empowered IRBs to approve, require modifications in planned research prior to approval, or disapprove research. An IRB performs critical oversight functions for research conducted on human subjects that are scientific, ethical, and regulatory.

IRBs are most commonly used for studies in the fields of health and the social sciences, including anthropology, sociology, and psychology. Such studies may be clinical trials of new drugs or devices, they may be studies of personal or social behavior, opinions or attitudes, or they may be studies of how health care is delivered and might be improved.


The purpose of IRB

The purpose of an IRB review is to assure, both in advance and by periodic review, that appropriate steps are taken to protect the rights and welfare of humans participating as subjects in a research study. To accomplish this purpose, IRBs review research protocols and related materials (e.g., informed consent documents and investigator brochures) to ensure protection of the rights and welfare of human subjects of research. The chief objectives of every IRB protocol review are to assess the ethics of the research and its methods, to promote fully informed and voluntary participation by prospective subjects who are themselves capable of making such choices (or, if that is not possible, informed permission given by a suitable proxy) and to maximize the safety of subjects once they are enrolled in the project.
