Trials can be imported from ClinicalTrials.gov into the CTRP database in the following ways:
- The system imports Industrial and Consortia trials registered in ClinicalTrials.gov into the CTRP database nightly. For information, refer to About Automatic Imports of Trials from ClinicalTrials.gov.
- You can import new and updated trials from ClinicalTrials.gov manually. For instructions, refer to Importing Trials from ClinicalTrials.gov Manually.
For both types of imports, keep in mind the following points:
- If the system finds a match between a trial in ClinicalTrials.gov and a rejected one in the CTRP, the system will not import the trial. For instructions, refer to Deleting NCT-IDs from Rejected Trials.
- If the Official Title does not exist for an imported trial, the system substitutes the Brief Title as the Official Title. If ClinicalTrials.gov later adds an Official Title, then during the nightly update, the system updates the Official Title of the trial in the CTRP database to match the ClinicalTrials.gov Official Title.
- Log files are recorded for each import. For information, refer to About ClinicalTrials.gov Import Logs and Searching for ClinicalTrials.gov Import Logs.
- Fields that have been updated as a result of the import are logged on the Updates tab on the Trial History page for each updated trial. For instructions, refer to Acknowledging Trial Updates.
