Reactivating a Closed IRB Study

Re-opening a closed study is handled on a case by case basis by the Institutional Review Board (IRB). You can request reactivating a closed study up to 12 months after the study was closed. After this time, a new application submission will be required.

To re-open the study the Principal Investigator (PI) must submit the following:

  • The reason why the study was closed and the reason why it needs to be re-opened.
  • Confirmation that no participants were enrolled and no data collection occurred while the study was closed and that this is the continuation of the same study.
  • If applicable, a modification with any requested changed to the application, personnel, etc. since the application was last approved.
  • If applicable, an updated continuing review.
  • If participants need to be notified of the re-opening, the PI must explain how this will be accomplished.
