Closing Studies

Expedited and Full Board

Please submit a Study Closure Form and closure materials to OHR. Studies can be closed when subject enrollment is closed, all follow-up research activities have been completed, and the analysis of identifiable data has been completed. Please be sure to reference the IRB submission, protocol, and consent form (as applicable) for data retention plans.

Please submit the Study Closure Form at least 30-60 days prior to the study’s expiration date.


  • PIs who are departing GW are expected to close or transfer their projects to a new PI prior to leaving the university.
  • PIs of student projects are responsible for ensuring that students submit the Study Closure Form prior to graduation.
