Any changes or modifications to your study must first be approved by the IRB before the change is implemented.
- Targeted population
- Recruitment plans
- Research procedures
- Study instruments
- Study sites
- Research personnel
Implementing changes without prior IRB approval is considered a protocol violation and subject to a noncompliance review. Pre-approval may not be required if the change is made in order to eliminate an immediate harm to participants, such as a breach of confidentiality, death of the principal investigator, unresolved participant complaints, and change in labeling or withdrawal of marketing.
