Which statement marks the conclusion of a clinical trial?

• A. Final data lock, analysis, reporting, and archiving of the TMF.
• B. Interim data analysis during recruitment.
• C. Enrollment suspension.
• D. Trial completion announcement.

Answer: (A)

The ending of a clinical trial is defined by finalizing all data and documentation: locking the dataset so no further changes can be made, performing the final analyses, preparing and sharing the results, and archiving the Trial Master File for regulatory and archival purposes. The final data lock ensures the data used for analysis are complete and unaltered, which is essential before any conclusions are drawn and reported. Archiving the TMF preserves all essential study records for audits and future reference, signaling formal closeout. Interim data analyses during recruitment, enrollment suspension, or a simple trial completion announcement do not itself signify the trial’s conclusion, since they occur while the study is still ongoing or before all closeout tasks are finished.
