Comprehensive Guide to ICH GCP E6(R3)
Comprehensive Guide to ICH GCP E6(R3)
Physician Led Research, Patient First Results
The ICH GCP E6(R3) update marks a significant evolution in the Good Clinical Practice framework.
It replaces prescriptive language with 11 modernized, principle-based guidelines that emphasize flexibility, proportionality, and digital readiness.
Key additions include Quality-by-Design (QbD), risk-based approaches, and better integration of real-world evidence and decentralized trial elements.
The structure now includes:
• Annex 1: Traditional interventional clinical trials
• Annex 2: Decentralized, pragmatic, and real-world data trials

Investigator and Sponsor Responsibilities
Investigator responsibilities include patient care, data integrity, investigational product management, and proper delegation. ALCOA+ principles apply.
Sponsors must embed QbD during protocol design, implement risk-proportionate quality systems, oversee CROs/vendors, ensure timely safety reporting,
and ensure proper document retention per local law..
Ethics and IRB/IEC Oversight
Independent ethics committees review all aspects of study design and participant rights. IRB/IEC must approve informed consent formats,
assess subject compensation, and include members with diverse and relevant expertise. Ongoing reviews are required based on study risk.
Digital and Computerized Systems
Digital systems must be validated based on risk. Key elements include robust audit trails, cybersecurity protocols, encrypted data handling,
controlled user access, and backup/continuity plans. These systems must align with FDA Part 11 and EMA Annex 11 standards.
Monitoring, Auditing, and Risk Management
Risk-based monitoring is central to E6(R3), combining remote, central, and on-site strategies. Quality assurance includes root cause analysis, CAPA,
and continuous improvement. Sponsors must audit vendors and manage protocol deviations within an integrated risk framework.
Protocol Development and Essential Records
Protocol development should follow a QbD model: define endpoints, assess operational feasibility, align with estimands, and limit data to essentials.
Essential documents must be version controlled, metadata-tagged, and stored in validated systems like eTMF.
Applying GCP to Decentralized, Pragmatic, and Real-World Data Trials
E6(R3) Annex 2 supports decentralized trial modalities. It allows
- eConsent with comprehension checks
• Direct-to-patient IP shipments with real-time tracking
• Televisits and local lab integrations with CLIA/ISO standards:
• Use of validated wearables and mobile apps
• Real-world data linkage from EHRs with documented provenance
These adaptations retain GCP principles while modernizing operations.
