group ethics review were published and the term institutional review board was born [7].

       1972 – The US Public Health Service’s Tuskegee Syphilis Study [8], which began circa 1932, is publically exposed for its deficiencies and ethical failures.

       1974 – The US Congress reacts to the Tuskegee study episode by enacting the National Research Act [9] (National Research Act 1974) which establishes the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research (National Commission).

       1976 – the US Congress is provided a report [10] from the General Accounting Office which reported that based on a special survey of sponsor and investigator inspections 74% failed to comply with legal requirements pertaining to informed consent, drug accountability, adherence to protocol, record accuracy, and availability as well as the appropriate supervision by the clinical investigator. This report prompts Congress to recommend that FDA undertake adequate monitoring / inspection programs of clinical trial sponsors, investigators, and institutional review boards.“the Food and Drug Administration (FDA) is not adequately regulating new drug testing to insure that human subjects are protected and the test data is accurate and reliable.”

       In 1979 the Belmont Report [11] is published by the National Commission and joins the Nuremburg Code and Declaration of Helsinki as a fundamental policy document describing the application of ethical principles such as respect for persons, beneficence, and justice in the conduct of behavioral and biomedical research involving humans.

       1980s – Global regions, countries with mature drug regulatory systems such as Japan, the European Union (EU), and the United States, as well as global health authorities, e.g. World Health Association, independently establish or enhance regulations and guidelines governing the conduct of human clinical trials. Harmonization of requirements for drug approval is championed by many.

       1990 – The International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) [12] is founded by the regulatory authorities and pharmaceutical associations of Japan, the United States and the European Union.

       1996 – The ICH guidance GUIDELINE FOR GOOD CLINICAL PRACTICE E6 (R1) [13] (ICH E6(R2) is finalized. It remains the gold standard for the design, conduct, recording, and reporting of clinical trials involving human subjects. Note – It was revised in 2016 to (R2).

       2004 – The EU Clinical Trial Directive 2001/20/EC [14] becomes effective and EU member states must move to adopt it into their legal requirements. The Directive sets universal requirements for clinical trials including approval by an ethics committee, harmonization of technical requirements through participation in the ICH, and application of GCPs in the conduct of human trials.The verification of compliance with the standards of GCP and the need to subject data, information, and documents to inspection in order to confirm that they have been properly generated, recorded, and reported are essential in order to justify the involvement of human subjects in clinical trials.

       2011 – The International Standards Organization (ISO) in conjunction with its standard setting partners publishes the medical device version of the GCP requirements in the form of the standard ANSI/AAMI/ISO 14155 Clinical investigation of medical devices for human subjects – GCP [15] (ISO 14155‐2011). 14155 Represents the medical device version of the ICH GCP standard for pharmaceuticals. This publication solidified the application of GCP expectations for human clinical trials in essentially all investigative (unapproved) articles intended for the cure, mitigation, or treatment of disease and injury in man.

      This chronology does not however speak directly to the driving forces that were in play as the events unfolded and the progress towards an international acceptance of GCP as a standard was underway.

      GCP as we know it today was born not just out of tragic episodes in human experimentation such as the Tuskegee Syphilis Study and the abuses of Nazi researchers in the WWII concentration camps. It was very much a work‐product of the for‐profit drug industry which needed harmonized standards to facilitate the marketing application process among the world’s primary producers and consumers of pharmaceuticals. An additional motivation for the ICH concept was to remove duplicative testing which would reduce the exposure of humans to investigational medicinal products, unnecessarily. Viola!, the emergence of the ICH. The ICH was born out of collaboration between the regulatory authorities and industry trade associations. It therefore had the best of both regulatory thinking and for‐profit science. The newly born organization moved quickly to develop and propose a number of key guidelines which would benefit the entire pharmaceutical industry. GCP was one of the efficacy guidelines defining approaches to clinical trial activities. Others included clinical safety for Drugs Used in Long Term Treatment (E1) and general considerations in clinical trials (E8).

      In 2015 the ICH took several steps to solidify its organizational presence and expand its influence. It established itself as an association under Swiss law and it invited regulators and industry counterparts from Switzerland, and Canada to join as full members. It also adopted a name change – The International Council for Harmonization – and continues to grow and prosper today.

      Notwithstanding the harmonization mission of the ICH, implementation of guidelines such as GCP even among the founding members of the ICH has not been identical. The European Union and Japan have adopted the GCP guideline into their legal requirements for the conduct of clinical trials. The United States has not, however, done so. The reasons for this difference in adoption of the GCP, as well as other ICH guidelines, lie primarily in the legal system supporting the regulatory framework. For example the United States has had in place regulations governing new drug studies since the early 1960s including requirements associated with informed consent. Modifying those regulations to integrate or adopt the GCP guideline would have been a monumental task. In addition, the system in place to modify/change regulations is a cumbersome one which would encounter difficulties and complexities in keeping up with the technology changes that can more efficiently be processed by a nongovernmental entity such as the ICH.

      Without doubt, the US FDA agrees with the ICH GCP guidance, they helped write it! The manner in which the FDA has integrated GCP into its regulatory scheme provides a good example of harmonization with its ICH counterparts as well as demonstrating its support and approval for the application of GCP for human clinical trials.

      Contemporaneous with the development of the ICH GCP was the development of a set of GCP expectations
