The review of progress in international harmonisation and the coordination of all measures is an important focus of the ICH. With this tool, an overview of the implementation status of ICH Guidelines under Step 5 of the ICH process is easily at hand:
A specific guideline or topic and/or an ICH member country can be selected in order to determine the implementation status, the date of implementation and the corresponding reference number of a Member State.

At “Step 5” level, the ICH Guidelines are implemented by the respective ICH Regulatory Members and Regulatory Observers in their countries. For ICH Regulatory Observers, the implementation of (certain) ICH guidelines is a prerequisite for becoming an ICH Regulatory Member.
