Background: The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) is undertaking a major revision of ICH E6 Good Clinical Practice (GCP) decided to involve external stakeholders in ICH-GCP renovation. Activities such as surveys and public conferences have taken place in the United States, European Union, and Japan. For stakeholder engagement in Japan, a designated research group conducted a survey of academic stakeholders. Methods: A total of 105 academic stakeholders from 18 institutions responded to the survey. The research group developed recommendations reflecting the survey results and the opinions from patients and the public. Results: The survey showed the top four principles needing renovation were (i) informed consent (Chapter 2.9, 12.4% of respondents believed it needed renovation), (ii) systems for quality assurance (Chapter 2.13, 9.5%), (iii) information on an investigational product (Chapter 2.4, 5.7%), and (iv) procedures on clinical trial information (Chapter 2.10, 5.7%). The top three sections identified as needing renovation were: (i) informed consent (Chapter 4.8, 27.6%), (ii) monitoring (Chapter 5.18, 22.9%), and (iii) composition, functions, and operations of the ethics committee (Chapter 3.2, 14.3%). Recommendations included clarification of ICH-GCP’s scope, proportionality in various aspects of clinical trials, diversity and liquidity of ethics committee members, modernization of informed consent procedures, variations in monitoring, and regulatory grade when using real-world data. Conclusion: The recommendations from Japanese investigators and patients have been submitted to the ICH E6 Expert Working Group, which will strengthen the robustness of the GCP renovation.
