What is the sponsor's primary role regarding trial quality?

• A. To ensure regulatory compliance, oversee the trial, and assure data integrity and subject safety.
• B. To recruit all participants.
• C. To perform all monitoring activities personally.
• D. To manage only financial aspects.

Answer: (B)

The key idea is that the sponsor bears the overall responsibility for trial quality. The sponsor sets the framework that ensures safety, integrity, and regulatory compliance across the study—this includes designing the protocol, establishing data management and quality assurance plans, supervising investigators and vendors, and ensuring proper monitoring and risk mitigation. In other words, the sponsor is responsible for the systems and oversight that keep the trial credible and safe for participants.

Recruiting all participants is not the sponsor’s primary duty; that task typically lies with investigators and study sites who interact directly with potential participants. Monitoring and day-to-day trial operations are usually carried out by qualified monitors or CROs hired by the sponsor, not by the sponsor personally. And managing only financial aspects would miss the fundamental responsibilities around safety, data integrity, and regulatory compliance that define trial quality.
