Good Clinical Practice
Clinical trial conduct, subject protection, and data credibility.
What this page does not claim
Educational orientation — not a determination of regulatory applicability, compliance, validation scope, or organizational approval.
WHAT IT GOVERNS
Good Clinical Practice is the international ethical and scientific standard for designing, conducting, recording, and reporting trials that involve human subjects (ICH E6). It protects the rights, safety, and wellbeing of participants and ensures the credibility of the data a trial produces — the two goals on which every marketing application ultimately rests.
WHY IT MATTERS
Unreliable trial data can put participants at risk and sink a submission years and hundreds of millions of dollars in. Informed-consent and source-data findings are among the most common FDA and EMA inspection citations, and a serious GCP breach can invalidate a pivotal study outright. GCP is where patient protection and data credibility are won or lost.
KEY FOCUS AREAS
Subject protection & informed consent
IRB/IEC oversight, a properly executed and documented informed-consent process, and the ethical safeguards that keep participant welfare ahead of the science.
Investigator & sponsor responsibilities
Clearly delineated duties — the investigator’s conduct of the trial at site and the sponsor’s oversight, safety reporting, and quality management of the whole programme.
Source data & the ALCOA+ trail
Source documents and the case report form linked by an intact, contemporaneous data trail, so a monitor or inspector can reconstruct exactly what happened to each subject.
Risk-based monitoring & oversight
A quality-by-design, risk-based approach (ICH E6(R2/R3)) that focuses monitoring and oversight on what matters most to subject safety and data reliability.

What is Good Clinical Practice (GCP)?
GCP is the international ethical and scientific standard for designing, conducting, recording, and reporting trials that involve human subjects. It protects the rights, safety, and wellbeing of participants and ensures the credibility of the data a trial produces — the two goals on which every marketing application ultimately rests.
What standard defines GCP?
The core standard is ICH E6, Good Clinical Practice, in its current revision ICH E6(R3). It sets the responsibilities of investigators and sponsors, the requirements for informed consent and ethics-committee oversight, and — through the R2/R3 revisions — a quality-by-design, risk-based approach to trial conduct and monitoring.
What does GCP require for informed consent?
GCP requires IRB/IEC oversight and a properly executed, documented informed-consent process in which participant welfare is placed ahead of the science. The consent must be obtained before trial procedures begin, using the approved version, and re-consent is required when material new information emerges.
