What should the investigator ensure about staffing and facilities for the trial?

• A. A small, indefinite staff is sufficient for the trial.
• B. Adequate facilities only for the first week of the trial.
• C. Adequate number of qualified staff and adequate facilities for the foreseen duration of the trial to conduct the trial properly and safely.
• D. Staff availability is optional if the protocol is clear.

Answer: (C)

Ensuring adequate resources means having enough qualified personnel and suitable facilities available for the entire anticipated duration of the trial, not just part of it. The investigator must provide staff who are properly educated, trained, and experienced to perform trial procedures and to supervise and monitor participants throughout the study. The facilities should be appropriate for all trial activities, capable of safely handling procedures, storage of investigational products, sample handling, and protecting participant privacy and safety, across every visit and procedure required by the protocol.

This coverage is essential for protecting participants, maintaining protocol adherence, and ensuring data integrity. If staffing or facilities are insufficient or only available briefly, safety could be compromised, protocol deviations could increase, and data quality could suffer. Therefore, the trial must be planned with an adequate number of qualified staff and suitable facilities for the foreseen duration to conduct it properly and safely.
