IRB or ERC approval of research is granted for one year. If research will continue beyond the one-year approval period, the researcher must reapply prior to the expiration date, using a Continuing Review (Renewal) form.
Lapses in research are not allowed. If a study's approval expires, all research activities, including but not limited to recruitment, data collection and analysis, must cease.
If research was originally exempt or expedited, the review category will remain the same. If research was originally full, the annual review may qualify for expedited status if it meets the criteria set forth under expedited category 8.
IRBNet will send automatic e-mail messages to principal investigators and sponsors to remind them of expiration dates; however, it is ultimately the researcher's responsibility to know when his/her approval is set to expire, and to reapply.
