In the IREx Study Setup, Reviewing IRBs/sIRBs can choose to have IREx notify relying sites when a study-wide amendment is posted, and request sites update their local considerations in IREx if necessitated by the study changes. If sIRBs choose this option, they can also opt to choose a number of days sites have to submit their updates in IREx. This feature is only available on studies in which the sIRB is collecting local considerations in IREx.
