International Clinical Trials Registry Platform (ICTRP)

About the WHO ICTRP

Following the Ministerial Summit on Health Research that took place in Mexico City, Mexico, in November 2004, participants called for the WHO to facilitate the establishment of: "a network of international clinical trials registers to ensure a single point of access and the unambiguous identification of trials".

This was further expanded on during the 58th World Health Assembly in Resolution WHA58.34 that called on the global scientific community, international partners, the private sector, civil society, and other relevant stakeholders to: "establish a voluntary platform to link clinical trials registers in order to ensure a single point of access and the unambiguous identification of trials with a view to enhancing access to information by patients, families, patient groups and others".

Aims of the WHO ICTRP

The main aim of the WHO ICTRP is to facilitate the prospective registration of the WHO Trial Registration Data Set on all clinical trials, and the public accessibility of that information.
