What is the main objective of the ICH GCP Guideline?

• A. To regulate pricing of medicines globally.
• B. To provide a unified standard to facilitate mutual acceptance of clinical trial data among regulatory authorities of ICH member countries and regions.
• C. To standardize laboratory procedures across all trials.
• D. To require all trials to use the same study design.

Answer: (B)

The main concept tested is that the ICH GCP Guideline provides a unified standard to facilitate mutual acceptance of clinical trial data among regulatory authorities across ICH member countries and regions. It sets ethical and scientific quality requirements so trials protect participants and produce credible, reliable data that regulators can rely on when evaluating new medicines. This harmonization helps regulators in different countries accept the same data without requiring duplicative studies. The other options miss the point: pricing is not part of GCP’s scope, which is about trial conduct and data quality; standardizing laboratory procedures is a concern of Good Laboratory Practice (GLP); and GCP does not require every trial to use the same study design, as designs may vary to fit different diseases, phases, and regulatory contexts while still upholding ethical standards and data integrity.
