Trial Master File
TMF
What a definition is not
A definition is SPEQ’s plain-language decode of how a term is used in practice, cited to the documents that define it. It is a practitioner reference, not legal or regulatory advice, it does not replace the definition in the source, and where a regulator’s wording differs the regulator’s wording governs.
The trial master file is the collection of essential documents that individually and collectively permit the conduct of a clinical trial to be evaluated and the quality of the data produced to be judged. It evidences that the sponsor and investigator complied with GCP and applicable requirements, and must be kept complete, contemporaneous, and inspection-ready throughout the trial and for the required retention period. Sponsor and investigator each hold their portions (the sponsor TMF and the investigator/site file).
A TMF is judged by the "reconstruct the trial" test: an inspector should be able to follow the file and understand the decisions taken and the conduct of the trial without needing tacit knowledge. Completeness and timeliness of filing are themselves GCP expectations, not clerical afterthoughts.
Electronic TMFs (eTMF) are widespread and must meet the same data-integrity and record-retention standards as paper — ALCOA+, controlled access, and validated systems where applicable.
- —Essential documents enabling trial conduct to be reconstructed and evaluated
- —Sponsor TMF and investigator site file are complementary halves
- —Must be contemporaneous, complete, and inspection-ready
- —eTMF must meet the same data-integrity and retention standards
