3.2.5 Common Properties of GXPs
So what is it that ties the three GXP disciplines together? It is the culture of quality and building quality into all aspects and processes that are employed. If you turn to Chapter 30 and the diagram depicting the quality management system you can visualize that whether the investigational product is being manufactured, undergoing preliminary testing to assess its toxicity, or being administered to humans as part of a clinical trial the same set of quality characteristics are brought to bear.
Qualification of people, places, and things must be performed against a standard or set of criteria. Training must occur not only in the general aspects of the discipline but also in the details which apply, for example a clinical trial protocol. Written procedures must be in place, trained against and followed. Keeping written procedures current is one of the most demanding, but necessary aspects of this quality characteristic. Maintaining records and documentation which is accurate and complete cannot be overemphasized. Documenting data and events whether by hand or electronically is essential; however, it remains one of the quality activities that is the most difficult to convince people is critical. Keeping records is not viewed as fun by many people. Ensuring that all involved parties and systems are engaged when making changes is a management step that demands inclusiveness. Operating under a management system that has identified the risks associated with the trial and which represent a critical to quality categorization along with any planned mitigation is a characteristic which evolved from the medical device manufacturing arena but has become an accepted and necessary practice throughout GXP. Learning and making changes based on implementing a corrective and preventive action program is also a process which was born in the medical device regulatory scheme but adds value to the clinical trial endeavor because it forces systematic change not just one off corrections. From the Quality Assurance standpoint auditing programs either internally or by external parties highlights not just the issues but also the successes in a program. Lastly having the involvement of management that is empowered to make changes and is committed to doing so when needed is key to completing the GXP scheme in general and GCP is particular.
3.3 Summary
Once a firm has decided to pursue a drug development process it enters a regulated environment which includes GLP, GCP, and cGMP. The plans, actions, and decisions associated with the firm’s drug development initiative must be in tune with and guided by these regulatory requirements. GCP is a part of the regulatory scheme not the entire regulatory scheme.

4 The Intersection of GCP and Regulation
P. Michael Dubinsky
GCP Key Point
GCP expectation intersects the entire functional scheme of clinical development for pharmaceutical medicinal products. Understanding the intersections is useful and enlightening.
The emergence of the ICH closely parallels with the emergence of current GCP because the ICH served as a catalyst for development of Standards such as the ICH E6(R2). The ICH‐GCP (R1) was one of the first standards developed by the ICH. It was recognized that such a standard was needed. Regulatory Authorities had worked on building the GCP expectations into their regulatory schemes by detailing them in codes or regulations then interpreting the codes using mechanisms such as inspections and industry meeting presentations. The World Health Organization (WHO) had pursued developing principles of good clinical research practice as early as the late 1960s however the WHO was not a regulatory or standard setting organization so their guidance did not represent requirements nor was it mandated under any laws. The regulatory authorities were not working collaboratively to further their GCP thinking and as a result the requirements across countries and regions were evolving differently. It took an industry‐regulatory authority initiative – The ICH – to open the door to establishing a pathway for harmonization of GCP as well as other drug development requirements. That initiative has flourished and expanded.
4.1 Introduction
In Chapter 1 – History of GCP outlines key aspects of the birth of the ICH organization and its growth from 1990 to the present day. This chapter will not repeat that material but rather will outline how the ICH E6(R2) reflects the harmonized expectations of the industry‐regulatory authority collaboration which began working to draft the GCP Efficacy Guideline almost immediately after the establishment of the ICH as an organization.
4.2 Objectives
The objectives of this chapter are to:
Demonstrate how the ICH E6(R2) Guideline serves to underpin those practices which support subject safety and data integrity within the context of meeting regulatory authority requirements.
Outline several ways the ICH guideline elements moved the conduct of clinical trials closer to meeting the expectation of regulatory compliance and best practices.
Since this text is devoted to explaining fundamental precepts for good clinical practice this chapter will not address each topic area but rather select several examples of how the ICH E6(R2) moves clinical research several steps higher than the regulatory expectations which are generally acknowledged to be the minimum requirements for compliance with a statute, directive, or code.
