ICH E6(R3) introduces innovative provisions designed to apply across various types and settings of clinical trials, ensuring continued relevance in the face of ongoing technological and methodological advancements. This guideline provides a new language to facilitate innovations in clinical trial design, technology, and operational approaches. It encourages a risk-based and proportionate approach to conducting clinical trials, promoting fit-for-purpose solutions. It fosters transparency through clinical trial registration and result reporting and offers additional guidance to enhance the informed consent process.​

The overarching principles and Annex 1, adopted by ICH and CHMP, came into effect on 23 July 2025.

With the public consultation now concluded, the Annex 2 is expected to be finalised later in 2025.
