Which countries have officially adopted ICH-GCP E6(R2) as a standard, in addition to U.S., EU, Japan, Canada, and Australia?

The International Council for Harmonisation (ICH) has expanded significantly beyond its founding members. Brazil's ANVISA (2016), China's NMPA (2017), and India's CDSCO (2023) have all become ICH Regulatory Members and have officially implemented or aligned their national good clinical practice regulations with the ICH-GCP E6(R2) standard. This adoption by major global players in clinical research signifies a broader international commitment to harmonized standards for conducting clinical trials, ensuring data quality and protecting human subjects. These countries represent a major expansion of the ICH framework into new regions.

B. Switzerland: While Switzerland's regulatory authority, Swissmedic, is an ICH Regulatory Member (since 2015) and has adopted ICH-GCP, it is often considered part of the core European regulatory environment and its membership predates that of Brazil and China. The question likely seeks to identify more recent, non-founding members from outside this traditional sphere.
