The sponsor's audit plan and procedures should be guided by which factors?

• A. The importance of the trial to regulatory submissions, number of subjects, type and complexity, level of risk, and identified problems.
• B. The same plan for all trials regardless of risk or size.
• C. Focus only on data accuracy, not safety or compliance.
• D. Auditing is optional and not linked to regulatory expectations.

Answer: (A)

In ICH GCP, sponsor oversight is guided by a risk-based approach that tailors the audit plan to the specifics of each trial. The plan should be shaped by factors that influence risk and regulatory impact, so resources are focused where they matter most. The most important factors include how critical the trial is for regulatory submissions, how many subjects are involved, the trial’s type and complexity, the level of risk to participants, and any problems already identified. When a study has higher risk, more complex design, or larger enrollment, the audit scope, frequency, and procedures should be intensified to examine safety, informed consent, data integrity, and compliance processes. This alignment helps protect participants and ensure data quality while meeting regulatory expectations for sponsor oversight.

Treating every trial the same ignores how risk and impact vary, which can leave significant issues unchecked. Focusing only on data accuracy omits safety and compliance considerations that are also essential components of a valid audit. Auditing is not optional in GCP; it’s a required part of sponsor responsibility to verify integrity and protect subjects.
