This page tree describes how to use CTRP to register, amend, and update clinical trials. The following table describes the circumstances in which you should use each submission type:

Submission TypeDescription
RegistrationUse the Register Trial feature for a trial that has not been registered with CTRP previously.
Amendment
 Update
Use the Amend Trial feature---for Complete trials only---when changes to the trial involve changes to the protocol document that require IRB approval.
UpdateUse the Update Trial feature when changes to the trial do not substantively affect the scientific conduct of the study, the study design, and/or the sites in which patients are enrolled on the trial. Update Trial also accommodates certain protocol document changes. (For instructions, refer to Protocol Document Updates.)
