This page tree describes how to amend trials currently registered and verified in CTRP.
In your role as trial owner, you can amend National, Externally Peer-Reviewed, and Institutional trials that have been registered with the CTRP previously and have reached the Abstraction Verified Response/No Response processing status. (Refer to Trial Processing Statuses.)Â You can amend a trial you submitted or own if the trial status is In Review or Approved. (Refer to Trial Status Values in the CTRP and ClinicalTrials.gov.)
The CTRO reviews and abstracts amended trial data just as it does with original submissions.
The ability to amend a trial is restricted by its trial status
You can not amend trials in the Complete, Administratively Complete, Withdrawn, or Terminated statuses.
Most of the information, including documentation, that is required for original submissions is also required in amendments. To ensure that these requirements are met, you can review, edit, and print your amended data using the Registration features prior to submission.
