Reviews & Renewals

When to renew a protocol

Approved protocols will remain active for three years. At the end of that period, a new protocol application must be completed and submitted as a new protocol. The new protocol must be on file and approved before the three-year expiration date of the existing protocol.

Protocol amendments

If your protocol has not yet expired, but you need to make changes to its details, you should amend the protocol instead.
