Which statement best describes the investigator's responsibilities in a regulatory environment?

• A. Delegates regulatory compliance entirely to the sponsor
• B. Assumes all responsibilities for complying with regulatory requirements
• C. Ignores regulatory requirements unless audited
• D. Ensures regulatory compliance only for their site

Answer: (B)

In regulatory contexts, the investigator carries the ultimate responsibility for ensuring the trial at their site complies with all applicable laws, regulations, and good clinical practice. This means they must oversee that the study is conducted according to the protocol, the sponsor’s provisions, and regulatory requirements, including proper informed consent, IRB/IEC approvals, safety reporting, and maintenance of essential documents. Delegation to staff or to the sponsor is allowed for day-to-day tasks, but the investigator remains accountable for the trial’s regulatory compliance as a whole. This is why the statement that the investigator assumes all responsibilities for complying with regulatory requirements best matches how these roles are viewed: accountability cannot be fully outsourced, and ongoing compliance is required—not just something checked during audits. The other options imply either complete delegation, neglect, or limiting responsibility, which do not reflect the investigator’s enduring obligation to uphold regulatory standards across the conduct of the trial.
