The ethical principles underlying GCP and informed consent trace their origin to which document?

• A. The Declaration of Helsinki.
• B. The Nuremberg Code.
• C. The Belmont Report.
• D. The CIOMS guidelines.

Answer: (A)

The main idea behind this question is understanding where modern GCP and informed consent get their ethical grounding. The Declaration of Helsinki is the foundational document that established international standards for conducting medical research involving human subjects, including the obligation to obtain voluntary informed consent, assess risks and benefits, and obtain independent ethical review. It refined and expanded earlier concepts in a way that has shaped GCP practices worldwide.

The Nuremberg Code first articulated the importance of voluntary consent, but the Helsinki Declaration provided the practical, widely adopted framework that directly informs current GCP requirements. The Belmont Report contributes a U.S.-specific ethical framework that influenced regulations, and CIOMS guidelines offer additional international guidance, but the original international standard underlying GCP and informed consent is the Declaration of Helsinki.
