Clinical Trial Registration and Results Reporting

Federal law and journal publication standards require that investigators register their clinical studies in a publicly accessible database. The database is a tool to support compliance with these rules and regulations.

You should register your study under your institution’s account. For account information and to learn about how to register your study, contact your institution’s Protocol Registration System (PRS) administrator. Once you have a username and password, you can log in to your institution’s account.
