Which document contains the details of when, to whom, and in what manner the vendor data will be sent?

A Data Transfer Agreement (DTA), also known as a Data Transfer Specification (DTS), is the formal document created specifically to govern the transfer of data from an external vendor to the sponsor or CRO. This document precisely defines the operational details, including the transfer schedule and frequency (when), the recipients and contact points (to whom), and the technical specifications such as file format, transfer method, and security measures (in what manner). Its purpose is to ensure data is received in a consistent, timely, and usable format, making it the correct document for these details.

A. Project Plan: This document outlines the overall project scope, timelines, and resources, but lacks the granular, technical specifications of a data transfer.

B. Communication Plan: This governs the communication strategy among human stakeholders (e.g., meeting schedules, reporting lines), not the technical transfer of data files.

D. Data Management Plan (DMP): The DMP is a high-level document describing all data management activities. While it will state that vendor data will be transferred, it references the DTA/DTS for the specific operational details.

Section 7.6, External Data Management, states, "Specifications for external data transfers should be documented. This documentation may be referred to as a Data Transfer Agreement (DTA), Data Transfer Specification (DTS), or External Data Vendor Specification... The specifications should include... data structure and format... transfer schedule... [and] method of data transfer."

2. Prokscha, S. (2012). Practical Guide to Clinical Data Management (3rd ed.). CRC Press. In Chapter 12, "External Data," the text explains that a "data transfer specification" or "data transfer agreement" is required to define "the file layout, the transfer frequency, the transfer medium, and the contacts for both the sending and the receiving party" (p. 215).

3. Rondel, R. K., Varley, S. A., & Webb, C. F. (Eds.). (2000). Clinical Data Management. John Wiley & Sons. Chapter 10, "External Data," emphasizes the need for a Data Transfer Specification that details the "frequency of data transfers," "data format," and "transfer mechanism" (pp. 133-134).
