All research protocols approved by the IRB as expedited or full reviews shall be reviewed periodically. Intervals between consecutive reviews may not exceed 12 months. The interval between consecutive reviews may be less than twelve months if the IRB determines that the level of risk warrants more frequent reviews. Once a research project no longer involves human subjects (i.e., once the investigators have finished obtaining data through interaction or intervention with subjects or obtaining identifiable private information about the subjects), the protocol file may be closed rather than extended.

A notification, including instructions and forms for extending the protocol, will be sent to investigators 30-45 days prior to the expiration of the protocol approval date. However, investigators are responsible for ensuring that their IRB approval is current so if this notification is not received, investigators should contact the IRB for instructions on extending studies.  It's imperative to follow the timeline specified in the instructions, especially for full review studies, in order for the extension to be processed before the approval expires.

If the study is not complete and an extension is needed, a request for an extension must be submitted through TWU SharePoint. You will be prompted for your Portal username and password (NOTE: if accessing the site from an off-campus computer, add "" to your username). Once the SharePoint site has been accessed, press the "NEW" button to initiate the request and follow the instructions on the form. Click here to view a template of this form

If the study is complete, the investigator may complete the file closed process.
