News update

To look for a trial, click on “Home & Search”. Users are reminded that phase 1 trials, conducted solely in adults and which are not part of an agreed PIP, are not publicly available in the EU CTR. Please refer to European Guidance 2008/C 168/02 Art. 3 para 2 and Commission Guideline 2012/C 302/03, Art. 5.

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.
