- Risk-based approach: One of the most important features of the E6(R2) update was the introduction of a risk-based approach to trial design and conduct. This approach allowed clinical researchers to focus their resources on managing the most critical risks to trial participants and data integrity. Instead of applying the same level of oversight across all aspects of a clinical trial, E6(R2) enabled a more flexible and efficient approach, allowing trial managers to prioritize areas that posed the greatest potential risks. This had also huge impact on moving to targeted SDV, instead of the earlier 100% SDV method.
- Increasing trial complexity: Clinical trials had become far more complex than they were two decades earlier. Trials now involved larger participant groups, multiple study sites, and a greater variety of study designs. The guidelines needed to adapt to ensure the continued ethical management of these increasingly intricate trials. E6(R2) provided updated processes to manage these complexities effectively, ensuring that the safety of participants and the quality of the data were not compromised.
- Technological advancements: The 2016 update also reflected the rapid integration of new technologies in clinical research. Electronic data capture, remote monitoring, and other digital tools had become commonplace in trials, yet the original ICH-GCP guidelines did not fully account for their use. E6(R2) incorporated these advancements, providing clearer guidance on how to manage technology in clinical trials, such as handling electronic records and signatures while maintaining compliance with ethical standards.
What was the impact of E6(R2) update? The risk-based approach enabled researchers to streamline trial processes, reduce unnecessary burdens, and focus on the most important aspects of trial safety and data integrity. The update also improved the handling of trial complexity by providing clearer guidelines for multi-site trials and adaptive study designs. Researchers could now better manage large-scale, intricate studies while ensuring that ethical and scientific standards were upheld. Finally, the recognition of technological advancements in E6(R2) allowed clinical trials to integrate electronic systems more seamlessly. The update ensured that digital tools, such as electronic data capture and remote monitoring, could be used efficiently while maintaining the same high standards of data accuracy and participant protection that the original guidelines demanded.
Second Major Update: ICH-GCP E6(R3)
The second major update to the ICH-GCP guidelines, known as E6(R3), is currently in progress and expected to be implemented in 2024. This update builds on the revisions made in E6(R2) and is designed to reflect the continued evolution of clinical trials, incorporating the latest innovations in trial design and technology. The goal of E6(R3) is to further strengthen the guidelines to ensure that Good Clinical Practice remains relevant, effective, and adaptable to the future needs of clinical research. Here are the main reasons for the E6(R3) Update
- Non-traditional trials: The rise of non-traditional trial designs, such as decentralized trials that use remote technologies, has driven the need for updated guidelines that accommodate these approaches. E6(R3) includes provisions for non-traditional trials, ensuring that these innovative models can be conducted ethically and in compliance with Good Clinical Practice.
- Enhancing transparency: Transparency in clinical research has become increasingly important, and E6(R3) emphasizes this aspect by encouraging the public registration of clinical trials and the publication of results. This increased transparency promotes greater accountability and helps build public trust in clinical research.
- Strengthening the risk-based approach: Building on the introduction of a risk-based approach in E6(R2), the E6(R3) update aims to further advance this concept. By refining and enhancing the risk-based framework, E6(R3) encourages even more efficient trial oversight, allowing researchers and regulators to focus on the most critical aspects of clinical trials while reducing unnecessary burdens on lower-risk areas.
- Expanding applicability: While previous versions of ICH-GCP primarily focused on drug research, the E6(R3) update expands its applicability to other types of clinical research, including device trials, behavioral studies, and other non-drug clinical investigations. This expansion makes the guidelines more flexible and relevant across a wider range of clinical research fields.
- Improving efficiency and data integrity: A key focus of the E6(R3) update is improving the efficiency of clinical trial processes, particularly in record management and data integrity. By streamlining these areas, the guidelines aim to reduce operational burdens while ensuring that the data collected during trials remains accurate, reliable, and secure.
- Clarifying roles and responsibilities: The E6(R3) update also seeks to provide greater clarity regarding the roles and responsibilities of sponsors, investigators, and other stakeholders involved in clinical trials. By clearly defining these responsibilities, the guidelines aim to improve collaboration and ensure that all parties are accountable for maintaining Good Clinical Practice standards.
One of the key changes in E6(R3) is the restructuring of the guidelines into three distinct parts to ensure better organization and flexibility:
