When a sponsor transfers responsibilities to a CRO, what must they ensure?

When a sponsor transfers responsibilities to a Contract Research Organization (CRO), it is essential for them to ensure oversight and documentation of those responsibilities. This is crucial because the sponsor remains accountable for the conduct of the clinical trial, even when the CRO is managing certain tasks. Proper oversight involves regular communication, monitoring progress, and verifying that the CRO is adhering to all regulatory and ethical requirements. Documentation is equally important as it serves as a record of what responsibilities were delegated, how they were managed, and how compliance was maintained. This not only helps protect the integrity of the study but also ensures that all legal and regulatory obligations are fulfilled.

In the context of the other options, while independence of the CRO and handling of ethical approvals are significant considerations, they do not replace the necessity for oversight and documentation. Moreover, the idea that the sponsor would have no additional obligations disregards their ultimate responsibility for the study’s compliance and integrity, regardless of the delegation to the CRO. Thus, comprehensive oversight and continued accountability are fundamental elements in the sponsor-CRO relationship.
