Key Principles of ICH-GCP Guidelines (E6 R2)
1. Ethical Conduct
Clinical trials should be conducted in accordance with the Declaration of Helsinki and ensure the rights,
safety, and well-being of participants are protected. Ethical review by an Independent Ethics Committee
(IEC)/Institutional Review Board (IRB) is mandatory.
2. Risk vs. Benefit
The anticipated benefits should justify the risks. Risk should be minimized by sound trial design and
monitoring.
3. Subject Rights, Safety, and Well-being
These take precedence over the interests of science and society. Informed consent and the right to withdraw
are crucial components.
4. Adequate Nonclinical and Clinical Information
Prior to initiating a clinical trial, adequate data from preclinical studies should support the rationale for the
study in humans.
5. Scientifically Sound Protocol
The trial must be based on a scientifically and ethically justified protocol. It should clearly define objectives,
endpoints, design, and statistical analysis.
6. Compliance with Protocol
All clinical trial activities must follow the protocol approved by the ethics committee and regulatory authority.
Amendments must be pre-approved unless they are made for immediate hazard removal.
7. Medical Care and Qualified Personnel
Qualified medical professionals (physicians or dentists) should be responsible for medical decisions during
the trial.

8. Informed Consent
Voluntary, informed consent must be obtained from every participant before any trial-related procedure.
Consent should be documented and re-consented if changes occur.
9. Confidentiality of Records
Subject confidentiality must be protected. Records that identify participants should be kept confidential and
comply with data protection regulations.
10. Good Manufacturing Practice (GMP) for Investigational Products
Investigational products should be manufactured, handled, and stored in accordance with GMP and used per
approved protocol.
11. Quality Assurance and Quality Control
Systems with procedures that ensure the quality of every aspect of the trial must be implemented, including
monitoring, auditing, and data verification.
12. Data Integrity and Accurate Reporting
Data should be recorded, handled, and stored in a way that allows accurate reporting, interpretation, and
verification. Source data should be accessible and verifiable.
13. Confidentiality and Record Retention
Essential documents should be retained to allow for verification and audits by regulatory bodies. Records
must be stored securely and retained for a period defined by regulation.
