What is the primary purpose of Good Clinical Practice (GCP)?

• A. Protect the rights, safety, and well-being of trial subjects and ensure credibility of data.
• B. Accelerate regulatory approval for new drugs.
• C. Standardize laboratory procedures across sites.
• D. Minimize the cost of clinical trials.

Answer: (A)

Good Clinical Practice establishes ethical and scientific standards for conducting trials involving human participants. The primary purpose is twofold: to protect the rights, safety, and well-being of those volunteering for research, and to ensure that the data generated are credible, reliable, and accurate. This means trials must obtain informed consent, be overseen by independent ethics committees or IRBs, follow a sound protocol, maintain complete and accurate records, monitor safety, and report results honestly.

This focus on participant protection paired with data integrity is what makes this the best choice. While credible data can support regulatory decisions, GCP itself isn’t about accelerating approvals. It’s also not about standardizing laboratory procedures across sites (that’s more associated with other guidelines), nor is it about minimizing costs—the emphasis is on ethical conduct and reliable data, even if that affects cost or duration.
