Renewals / Extensions

All research protocols approved by the IRB as a full review shall be reviewed annually. 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 in order for the extension to be processed before the approval expires.

To extend a Legacy study (a study submitted to the IRB prior to the Cayuse implementation), a completed Extension Request Form must be emailed to irb@twu.edu with the PIs name, campus, and protocol number in the subject line. To extend a study submitted through Cayuse, a renewal submission must be initiated in Cayuse following these detailed instructions, Renewal Submission.
