Why must the Study Director maintain independence from QA activities?

• A. To ensure the director can override QA.
• B. Independence is not required.
• C. QA and Study Director have the same function.
• D. To avoid conflicts of interest and ensure objective study oversight.

Answer: (D)

Independence between the Study Director and QA is essential to prevent conflicts of interest and to ensure objective oversight of the study. The Study Director is responsible for the technical conduct of the study, protocol adherence, and data integrity, while QA independently monitors compliance with SOPs, GLP requirements, and study quality. If the Study Director could influence or override QA findings, monitoring and deviations might be biased or suppressed, compromising data reliability. By keeping QA independent, findings are reported without pressure, issues are addressed impartially, and the overall quality and regulatory acceptability of the study are maintained.
