The field of clinical research is continuously evolving, and with the introduction of ICH GCP R3, we are witnessing a transformative shift towards more ethical, patient-centered, and quality-driven studies. The latest revision of the International Council for Harmonisation (ICH) Good Clinical Practice (GCP) guidelines brings key updates that enhance patient engagement, data governance, ethics, and quality by design. These changes aim to improve the reliability of clinical trials while ensuring the safety and well-being of participants.
