What is the stated general expectation about on-site monitoring in trial monitoring guidance?

• A. There is a need for on-site monitoring before, during, and after the trial
• B. On-site monitoring is never required
• C. On-site monitoring should be replaced by remote only
• D. On-site monitoring is optional for all trials

Answer: (A)

Monitoring is designed to protect participants and ensure data integrity, and it traditionally involves on-site visits at key points in a trial. Before the trial starts, an on-site check helps confirm that the site is prepared: proper staff training, appropriate facilities, approved consent templates, and that essential documents and systems are in place. During the trial, on-site monitoring verifies that the conduct aligns with the protocol and GCP, checks that consent was properly obtained, confirms eligibility, ensures accurate data entry and timely SAE reporting, and resolves data questions with source-document verification. After the trial, a close-out or post-study visit helps confirm that all records are complete, queries resolved, and appropriate archiving is in place. While modern monitoring also uses remote and centralized approaches and a risk-based mix of methods, the guidance generally expects on-site monitoring to occur across these stages to safeguard rights, safety, and data quality. That makes the option describing monitoring before, during, and after the trial the best answer.
