EudraCT (European Union Drug Regulating Authorities Clinical Trials) is the European Clinical Trials Database of all CTIMPs with at least one site in the European Union (predominantly for CTIMPS started prior to January 1, 2021).

A EudraCT number is required in order to apply to the Medicines and Healthcare products Regulatory Agency (MHRA) for a Clinical Trial Authorisation (CTA) and to apply for REC approval of your clinical trial. CTIMPS which began before 2021 will still need to register and report results on EudraCT. CTIMPS beginning on or after January 1, 2021, will only need to apply for a EudraCT number, but not report results on EudraCT.

You should receive a response within three working days. Once the EudraCT number has been created, it will be forwarded to you.

Clinical Trials Before January 1, 2021

For CTIMPS registered on EudraCT which began before 2021, you will still need to report results on EudraCT. After January 1, 2021, the MHRA will no longer have the ability to update information on EudraCT so you will need to email the MHRA when you have reported results on EudraCT by following the steps below:

  • You must send a short confirmatory email to The subject line of the email notification must state ‘End of trial : result-related information: EudraCT XXXX-XXXXXX-XX’ once the result-related information has been uploaded to the public register and provide a link. If your clinical trial is not on a public register, summary results should be submitted by email to An acknowledgement letter will not be sent for this submission.
  • You should also submit a final report to the Research Ethics Committee within the same timeframe for reporting the summary of results.
