Good Clinical Practice (GCP) is the international ethical and scientific quality standard for designing, conducting, recording, and reporting clinical trials involving human participants.
GCP ensures that the rights, safety, and well-being of research participants are protected while ensuring that clinical trial data are accurate, credible, and reliable. The standard defines responsibilities for sponsors, investigators, institutional review boards (IRBs), and other research stakeholders throughout the clinical trial lifecycle. Compliance with GCP supports regulatory acceptance of study data, strengthens inspection readiness, and promotes consistent, high-quality clinical research across global studies.
