Full Committee or Expedite Research
The IRB must review and approve all changes to previously approved Full Committee or Expedite research prior to implementing the changes. For additional information, see our guidance on Modifying Approved Research.
More information on how to submit a Modification can be found on our eIRB Information webpage.
Exempt and Minimal Risk Research
Studies that are Exempt or Minimal Risk (MR) do not need to submit modifications to the IRB for review and approval unless the modifications change the nature of the project from being Exempt/MR. See the Exempt Minimal Risk Research guidance, which outlines when modifications are required.
If a modification is not required, the IRB recommends downloading the relevant approved documents within eIRB, making the necessary changes, and saving them separately in your research files. All modifications not reviewed by the IRB should be documented systematically to maintain an accurate record of all study activities to date.
