Answer: (A)

The purpose of the Trial Master File is to serve as the evidence package that shows the trial was conducted appropriately and the data it generated are credible. It contains all essential documents that enable evaluation of the trial’s conduct and the data, such as the protocol and any amendments, regulatory and ethics committee approvals, informed consent forms, recruitment materials, correspondence, monitoring visit reports, deviations and corrective actions, data handling and source data verification records, the statistical analysis plan, and the final study report. This organized collection allows regulators, sponsors, and auditors to verify that the trial followed the approved plan and applicable regulations, and that the data are traceable and trustworthy. It isn’t limited to regulatory approvals, nor is it about tracking payments or storing unrelated notes.
