The International Conference on Harmonization (ICH) is an organization that brings together regulatory authorities and pharmaceutical industry representatives from Europe, Japan, and the United States to discuss scientific and technical aspects of drug registration. It was established in 1990 to achieve greater consistency in technical guidelines to make the development and availability of new medicines more efficient while maintaining high standards of safety and efficacy. The ICH process involves five steps to build scientific consensus and adopt harmonized guidelines on quality, safety, efficacy, and multidisciplinary topics.
