When do I need to submit a modification application?

You will submit a modification application if you:

  1. Have already received NCU IRB approval
  2. Need to update information on your recruitment materials, consent letter, and/or information letter

For example, if you are adding compensation to your study, then you must update your recruitment materials and consent letter to include this information and will thus need to submit a modification application.

The IRB member will determine, based on the modification, if a new IRB application must be submitted.
