A Trial Master File, or TMF, is the organized collection of essential documents showing how a clinical study was conducted. At a research site, related materials may also be maintained in an investigator site file or study binder. For sponsors and CROs, the practical question is whether relevant documents can be located, understood, and connected to the study activity they support.
ALCOA-C is a data-integrity framework for records. It means documentation should be attributable, legible, contemporaneous, original, accurate, and complete. In practical terms, a record should show who created it, be readable, be made at the required time, preserve the original source or supported copy, reflect facts accurately, and include necessary information.
A query is a question about study data or documentation that needs clarification. Query resolution should address the specific question using supporting source documentation and preserve the record of what occurred. A correction should not rewrite history. The site's designated process determines how a query is received, assigned, documented, escalated when needed, and closed.
Sponsors and CROs can ask focused verification questions: Who owns each TMF or site-file section? How are missing, updated, or superseded documents tracked? How are corrections linked to source records? Who receives monitor or data-manager queries? How is follow-up documented? Coordinators may support document organization and query follow-through under investigator oversight.
Use the designated research contact to verify the site's current document-control and query-resolution process. Do not send study files, source materials, or identifying information through the consultation form, Mood Guide, or general contact fields. Provide the research contact with a concise list of TMF sections, document categories, or open queries to discuss through the confirmed secure channel.
Before a monitor discussion, separate questions into document location, source support, and follow-up status. For each item, identify the record being reviewed, the specific question, the available supporting source, and the person responsible for the next response. This makes it easier to distinguish a missing document from a clarification request and to track open items without altering the underlying study record.
