About Trial Registration
How to Register a Trial
You cannot register a trial with WHO. The WHO ICTRP is not a clinical trials registry.
To meet the requirements of the International Committee of Medical Journal Editors (ICMJE) you can register your trial with any Primary Registry in the WHO Registry Network or an ICMJE approved registry.
To meet WHO requirements for transparency and publication, it is only necessary for your trial to be registered once, in either a Primary Registry in the WHO Registry Network or an ICMJE approved registry.
NOTE: Regulatory, legal, ethical, funding and other requirements for oversight and conduct of clinical trials differ from country to country. It is recommended that those responsible for conducting a clinical trial check to make sure they are complying with the specific requirements of each country.
