Overview

Is your study registered with ClinicalTrials.gov? Federal lawjournal publication standards, and National Institutes of Health (NIH) policy require investigators to submit their clinical studies registration and results to a publicly accessible database. The ClinicalTrials.gov Protocol Registration System (PRS) is an online tool that meets these requirements.

ClinicalTrials.gov is a home for information on publicly and privately funded clinical studies on a range of diseases and conditions. It supports improved transparency and reduces duplication of effort by improving public access to information, providing information for clinicians and their patients, and providing researchers with an overview of a specific field of research.
