WHO establishes an International Clinical Trials Registry Platform (ICTRP)

The World Health Organisation (WHO) held a consensus meeting in New York in October 2004 that brought together government research institutions, pharmaceutical industry representatives, journal editors, researchers, and other leading experts to identify substantial common ground regarding trial registration. A general consensus was reached regarding the need for worldwide clinical trial registration. The so called "New York Statement 2004" noted the following:

The need for a global approach to clinical trials registration

  • Trials unambiguously identified
  • Consensus needed on which trials; data; timing and disclosure of results
  • One-stop search portal; publicly available
  • System is simple, effective, efficient
  • Capacity built where appropriate

The ICTRP can be accessed via: to develop an international, electronic search portal through which registries around the world can be located and accessed. This search portal became functional in May 2007. A second objective of the ICTRP is to establish processes for recognising registers of certain standards as Primary Registers. There are also plans for the development of a worldwide unique trial ID numbering system.
