News update

As of 31 January 2023, all initial clinical trial applications in the EU/EEA must be submitted through the Clinical Trials Information System. EU CTR continues to display information on EudraCT trials. EudraCT remains available for amendments to EudraCT trials, creation of PIP/Art 46 third country files (see FAQs), updating of EudraCT trials’ statuses and relevant submission of results.

To look for a trial, click on “Home & Search”. All approved trials on COVID-19 can be found here.

Following the issuing of the Joint Letter by the European Commission, EMA and HMA, National Competent Authorities and European Medicines Agency have sent reminders to sponsors who were not compliant with the European Commission guideline on results posting. Thanks to these reminders, the percentage of posted results substantially increased. However, for some trials the reminders were not successful: detailed lists of these trials can be found here.
