Which statement describes monitoring guidance for procedures?

• A. The sponsor's established written SOPs
• B. The investigator's personal preferences
• C. Regulatory guidelines only
• D. Monitors should follow the sponsor's established written SOPs and trial-specific monitoring procedures

Answer: (D)

Monitoring guidance comes from the sponsor’s formal procedures and the trial’s specific monitoring plan. Monitors must follow the sponsor’s written SOPs to ensure standardized, compliant practices across all sites, and also adhere to trial-specific monitoring procedures that address the unique aspects of that protocol. This combination provides both the general framework and the tailored steps needed for proper oversight, data integrity, and participant safety.

Relying on investigator personal preferences is not appropriate, and regulatory guidelines alone aren’t enough because they establish principles rather than the exact, day-to-day actions required at a given site. SOPs together with trial-specific monitoring procedures ensure consistent execution aligned with the protocol and regulatory expectations.
