If a protocol violation is discovered after data analysis, which steps should be taken?

• A. Document, assess impact, notify the sponsor/IRB, and implement corrective actions.
• B. Re-run the analyses without altering data.
• C. Delay reporting until the next data cut.
• D. Erase the data and re-run the study.

Answer: (B)

When a protocol violation is found after data analysis, the proper approach is to document the violation, assess its impact on data integrity and participant safety, notify the sponsor and the IRB/ethics committee, and implement corrective actions to prevent recurrence. Documenting provides an auditable record of what happened and why. Assessing impact helps determine whether the violation could have biased results, affected safety or informed consent, or altered the validity of conclusions, guiding whether re-analysis, re-consent, or other study modifications are needed. Notifying the sponsor and IRB ensures appropriate oversight and decisions about further actions, approvals, or whether any study changes are required. Implementing corrective actions closes the loop by addressing root causes and reducing the risk of recurrence. Re-running analyses without altering data would not address the violation and could misrepresent the integrity of the study. Delaying reporting until the next data cut postpones necessary oversight, and erasing data to re-run the study destroys the original record and undermines regulatory and ethical standards.
