A section that did not exist before

Open ICH E6(R2) -- the version that governed clinical trials from November 2016 until E6(R3) took effect -- and search for a dedicated section on data governance. You will not find one. E6(R2) addressed data through scattered provisions: Section 4.9 on recordkeeping, Section 5.5 on trial management and data handling, Section 5.18 on monitoring. The word "governance" appeared exactly zero times.

Now open ICH E6(R3), finalized on 06 January 2025, and turn to Annex 1. Section 4 bears a title that would have been unthinkable in 1996: "Data Governance -- Investigator and Sponsor." It spans three major subsections (4.1 Safeguard Blinding, 4.2 Data Life Cycle Elements, and 4.3 Computerised Systems), each with extensive sub-provisions. It introduces a data lifecycle framework. It establishes computerized systems requirements with specificity that E6(R2) never attempted. And it applies proportionality principles that fundamentally change how sites should think about data controls.

This is not a minor revision. It is a structural acknowledgment that clinical trial data have become too complex, too voluminous, and too dependent on electronic systems to be governed by recordkeeping rules designed in an era of paper binders and carbon-copy case report forms.

For the coordinator, Section 4 matters because it defines the governance environment in which every data point you create must now exist. The data integrity criteria we defined in the previous lesson tell you what good data look like. Section 4 tells you what good systems for managing those data look like -- and where the coordinator fits within those systems.
