ClinicalTrials.gov is a global platform for registering the clinical trials. It is not a World Health Organization (WHO) recognized primary registry. However, the clinical trials registered on this registry fulfill the criteria for publication of the manuscript in an International Committee of Medical Journal Editors (ICMJE) accredited journal. The registration of protocols and submission of results is governed by the NIH Final Rule (42 CFR Part 11), which has been in effect since January 18, 2017. This regulation requires registration and results reporting for phase 2-4 interventional clinical trials. Phase 1 and observational trials can be registered voluntarily on clinicalTrials.gov.
