Page History

You can retrieve existing trial records once you have registered for an account. See Creating CTRP Accounts.

After you have selected your search criteria, you can further limit or expand your search for trials as follows:

• Use the Search All Trials feature to search for all trials registered with the CTRP from all organizations/accounts, whether or not you are the submitter or owner.
• Use the Search My Trials feature to search for trials that you own, whether or not your organization is listed as the lead organization or participating site.
• Use the Search Saved Drafts feature to search for trials that you have saved as drafts but have not submitted.

The search feature you choose determines which categories of trials will be returned, and the actions you can perform with those results, as shown in the table below. See Working with Search Results for rules that determine which trial details are displayed.

How to Search for Existing Trials
