What sponsors should document when overseeing a CRO under ICH E6(R3)

Allocation does not remove oversight

ICH E6(R3) distinguishes allocation of trial activities from sponsor oversight. When important activities are transferred to a service provider, the sponsor still needs a proportionate way to understand performance, make decisions, and address material risk.

A practical evidence set

Responsibility and interface record

Document who performs each important activity, who reviews it, who decides when thresholds are exceeded, and how the parties communicate.

Risk-based oversight plan

Identify the activities and data that matter most to participant protection and reliable results. Define the signals, cadence, and thresholds used for sponsor review.

Governance records

Meeting records should capture material observations, decisions, accountable owners, target dates, and unresolved dependencies, not only presentation slides.

Issue and escalation history

Material issues need a clear category, assessment, owner, escalation route, decision, action, and closure evidence.

Corrective-action effectiveness

Completion of an action is not the same as confirmation that it worked. Record how effectiveness was evaluated.

Sponsor decisions

A concise decision log helps reconstruct what the sponsor considered, what was decided, why, and what follow-up was required.

Keep documentation proportionate

Oversight evidence should reflect the importance and risk of the activity. The goal is not to duplicate every CRO record. It is to show that the sponsor had an intentional process for seeing, evaluating, deciding, and following through.
