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.

      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.

      The thirteen principles of ICH E6(R2) set a cultural tone which brings together ethical considerations, scientific requirements, and regulatory details in a succinct set of statements that are not always found in codes or regulations. In the United States, the FDA would have described such aspects in a preamble to a set of proposed regulations but would not have memorialized such principles in the regulations that are promulgated. However, having a set of principles to draw on gives the clinical trial players a set of cultural and ethical building blocks to use as they develop an investigational plan, prepare a protocol and train staff to conduct a clinical trial.

      The high‐level statements of principle that are found in this section of the ICH E6(R2) provide a reference point for just about every requirement that can be found in the lengthy and detailed requirements of the regulatory authorities. One could easily substitute the term policy for principles. The thirteen principles are the policies that will govern the entire scheme of a clinical trial activity from the time an application is submitted to a regulatory authority to the time the last subject is enrolled. See Chapter 6.

      4.4.1 Good Clinical Practice (GCP)

      A standard for the design, conduct, performance, monitoring, auditing, recording, analyses, and reporting of clinical trials that provides assurance that the data and reported results are credible and accurate, and that the rights, integrity, and confidentiality of trial subjects are protected.

      Taking several of the functional steps included in this definition one can quickly understand how the contents of the Guideline/Standard are structured.

      Design – The standard calls for the development of a scientifically sound protocol and investigator’s brochure. The Standard then proceeds to list the content expectations for each document. The Sponsor of a trial need only follow the Standard.

      Conduct – The Standard outlines expectations which inform the players how to conduct a trial. For example, obtaining approvals from the IRB as well as the appropriate regulatory authority prior to starting the trial; obtaining informed consent from subjects; maintaining data confidentiality and ensuring product accountability for the IMP. These are just a few examples.

      Records and Record Keeping – Ensuring the integrity of data is a must. The ICH E6(R2) includes details about the types of records that are necessary and how to manage those records. Examples are the Case Report Forms, product accountability and the entire Section 8 which outlines the essential document needs for the three phases of the trial.

      Reporting – There are a number of reporting requirements that are in place for a clinical trial to be in sync with the requirements of regulatory authorities. Reporting of adverse events, progress reports, final reports, reports of monitoring the trial sites and audit reports come to mind. The Standard references all these types of reporting expectations and others.

      This is just a brief listing of the manner in which the Standard, through well‐reasoned and thoughtful development, manages to encompass the full range of functional activities associated with clinical trial conduct.

      The ICH E6(R2) brings together the key functional areas of the drug development process that call for the application of the principles. If you wanted to study the requirements governing subject safety and data integrity from the FDA regulations you would need to organize the requirements from several different sections of the Code of Federal regulations. The ICH E6(R2) contains the information necessary to put in perspective the responsibilities of the sponsor, investigator, and IRB/EC all in one document. The applicable requirements of the respective regulatory authority are always referenced for details but the pathway for compliance with expectations that underpin subject safety and data integrity are available in one place.

      Standard setting organizations are generally seen as just that the “standard” setters. They have recognition as being thorough, authoritative, and quality oriented. The ICH is no exception and the ICH E6(R2) is hands down the final word when it comes to what constitutes good clinical practice. There are versions of the ICH E6(R2) good clinical practice guidelines published but for the most part they are renditions of the ICH E6(R2) which have been adapted to fit into the pharmaceutical regulatory scheme of a country, e.g. India. In addition organizations such as the World Health Organization (WHO) recognize the need for instructions such as that in ICH E6(R2) but are not standard setting entities themselves. The WHO has a handbook of GCP [1] but it is not advertised or promoted as a standard.
