This page tree describes how to use CTRP to update clinical trials that are currently registered and verified in CTRP. The ability to update a trial depends on multiple factors, as described in the following table:
| Factor | Description |
|---|---|
| Who can update a trial? | Only the trial owner. A trial may have more than one owner. To request ownership of a trial, contact your Site Administrator. (If you are a Site Administrator, refer to Managing Trial Ownership.) |
| What types of trials can be updated? | Only trials that have been registered with the CTRP previously. |
| At which trial processing statuses can a trial be updated? | Only trials that have been previously accepted. (That is, the processing status must be Accepted or a subsequent processing status.) For information, refer to Trial Processing Statuses. |
| Which parts of a trial record can be updated? | Only a subset of the information included with the original trial submission. For details, refer to Trial Attributes You Can Update. |
| What types of changes can be made as a trial update? | Only changes that do not require Investigational Review Board (IRB) approval. For examples, refer to Examples of Protocol Document Updates. |
You can also update the trial status and trial status start/completion dates without having to update other trial details. For instructions, refer to Updating Trial Statuses.
