Applicability begins with scope, not assumption.
ICH E6(R3)Interventional trials
Core use case for regulatory reliance and GCP evidence.
Sponsors and investigators
Both need evidence of responsibility, oversight, and participant protection.
Service providers and CROs
Delegation requires documented responsibilities and oversight.
Regional implementation
ICH Step 4 does not create identical legal effect everywhere on the same date.
Timing changes what can be responsibly claimed.

life sciences lensPrinciples
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.
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.
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.
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.
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.
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.
