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.
IRB approval of a protocol typically lasts about one year. Each year the protocol must be renewed. Approximately 2-3 months before your protocol's expiration date the IRB will send you a memo requesting renewal documents. Approximately 1-2 months before the expiration date you will receive a final reminder memo. Once the IRB has received these documents they will be reviewed.
