Good clinical practices (GCP) are international ethical and scientific quality standards for designing, conducting, recording, and reporting trials that involve the participation of human subjects. GCP provides protection for trial subjects, enhances the quality and integrity of trial data, and helps ensure that trial results are credible and reported appropriately. The seminar discussed the history and development of GCP, from the Nuremberg Code to the ICH guidelines, with the goal of establishing consistent standards that are acceptable globally.
