This page tree describes how to update trials that are currently registered and verified in CTRP.
Registration enables you, in the role of trial owner, to update trials that have been registered with the CTRP previously. You can update only those trials that have been previously accepted (i.e., the processing status must be Accepted or a subsequent processing status.)
You can also update the trial status and trial status start/completion dates without having to update other trial details. See Changing Trial Status Information for instructions.
Use 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. (See Protocol Document Updates.)
Use the Amend Trial feature---for Complete trials only---when changes to the trial involve changes to the protocol document that require IRB approval. You can update both trial and participating site information for Industrial/Other trials using the Available Actions column.
