An Introduction to Good Clinical P ractice

What does the term “Good Clinical Practice” mean? Good Clinical Practice (GCP) is defined in the International Conference on Harmonization (ICH) guideline as an international ethical and scientific quality standard for designing, conducting, recording and reporting trials that involve the participation of human subjects. This standard ensures that the rights and safety of the trial subjects are protected and that the trial results are credible.

A Brief History Following WWII and during the Nuremberg trials, it became clear what atrocities the Nazi doctors committed 'in the name of medical science'. During their trial the Nazi doctors argued in their defense that there was no international law or informal statement that differentiated between legal and illegal experiments on humans. On 17 April, 1947 two US doctors who worked for the prosecution on the trials, submitted a text with six points defining legitimate research. These six points became ten points and are now known as the Nuremberg Code.

A brief history II These ten items were later incorporated in the Declaration of Helsinki, written in 1964 by the World Medical Association (WMA), an international organization representing physicians. The declaration was a guideline that provided the highest ethical standards at that time.

A brief history III During the 1960s, Thalidomide was used in Europe as a treatment for insomnia, mostly in pregnant women. When the company who manufactured the drug made a submission to the FDA (US Food and Drug Administration) to market the drug on the American market, Frances Kelsey (an FDA employee) reviewed the application thoroughly and kept if off the market when she discovered that it caused birth defects when used on pregnant women.

A brief history IV Eventually, from the mid-1970s, the FDA found it necessary to reject clinical research from other countries, since they didn't have the same ethical and safety standards as the US. Europe and Japan each developed their own set of GCP guidelines, from the mid-1980s onwards. But the differences between the US, Europe and Japan remained and did not contribute to the economical efficiency of clinical trials: pharmaceutical companies had to invest in three different trials to globally market one single drug.

A brief history V 

In 1996, an International Conference on Harmonisation (ICH) was called into being, consisting of authorities of Europe, US and Japan and experts form the pharmaceutical industries. This led to an international, uniform standard to accept the results of clinical trials, as long as they are conducted according to the ICHGCP guidelines on Safety, Quality, Efficiency and Multidisciplinary.

13 principles of Good Clinical Practice 1.

Clinical trials should be conducted in accordance with the ethical principles that have their origin in the Declaration of Helsinki, and that are consistent with GCP and the applicable regulatory requirements.

Investigational products should be manufactured, handled, and stored in accordance with applicable good manufacturing practice (GMP). They should be used in accordance with the approved protocol. 

13 principles of Good Clinical Practice 1.

Systems with procedures that assure the quality of every aspect of the trial should be implemented.
