The International Clinical Trials Registry Platform (ICTRP) is a platform for the registration of clinical trials operated by the World Health Organization.
[1] The ICTRP combines data from multiple cooperating clinical trials registries to generate a global view of clinical trials worldwide, with a search portal that allows access to the entire dataset.
[2][3] It requires a minimum standard set of database fields, the WHO Trial Registration Data Set, to be present for a trial to be registered.
[4] All entries are given a Universal Trial Number (UTN) that identifies them uniquely.
[5] The organization has sought to assist various national governments in establishing their own clinical trials databases.
