Use case 01

Principles

Use this as a trigger for ICH E6(R3) applicability review, not as an automatic compliance conclusion. Core GCP principles frame participant protection and reliable results.

Use case 02

Annex 1 final

Use this as a trigger for ICH E6(R3) applicability review, not as an automatic compliance conclusion. The current final source gives operational expectations for interventional trial design and conduct.

Use case 03

Annex 2 draft/watch

Use this as a trigger for ICH E6(R3) applicability review, not as an automatic compliance conclusion. Additional trial-design and data-governance topics remain watch items until finalised and regionally implemented.

Use case 04

Quality by design

Use this as a trigger for ICH E6(R3) applicability review, not as an automatic compliance conclusion. Critical-to-quality factors should be identified and managed early.

Use case 05

Proportionate approach

Use this as a trigger for ICH E6(R3) applicability review, not as an automatic compliance conclusion. Controls should match risks to participants and data reliability.

Use case 06

Sponsor oversight

Use this as a trigger for ICH E6(R3) applicability review, not as an automatic compliance conclusion. Delegation does not remove sponsor accountability.
