sIRBs can now close studies that are complete on IREx by uploading the reason and date of closure, as well as the IRB determination letter. Closing a study notifies sites that the study has ended. The study remains accessible to all registered sites after a closure is posted, and all past approvals become read-only. A record of sites’ reliance details and a history of sIRB site approvals are still available in all IRB exports for metrics. For instructions on how to close a study, see our Quick Guide.

Here is what you will see for a closed study:

• Study page is grayed out with a Study Closed header at the top
• Status Summary Tab shows as Closed in Approval column
• IRB Dashboards show that a study has been closed
• Versions box shows that a study has been closed
• Exports show closed studies with date of closure
