Trial Registration and Results Reporting on

Registration, updating records, and results reporting of clinical trials has two main purposes:  to inform potential subjects, and to increase the likelihood that negative results of trials will be publically available, thereby promoting transparency and scientific integrity. The U.S. Government site for registering clinical trials is  A study is issued a NCT number when it is registered. A trial should only be registered and listed once. For investigator-initiated clinical trials, the Principal Investigator is considered the Responsible Party, and is the one who has to complete the registration.  For multi-center clinical trials, someone other than the local PI usually fulfills this responsibility. The Responsible Party who initially registered the clinical trial is also the one who must maintain the information about the trial, including updating recruitment information at least every 12 months and reporting final results if required.
