Clinical Trials Information System (CTIS): EU trials

This website supports access to clinical trials in the European Union (EU) and the European Economic Area (EEA), entered since the website launch on 31 January 2022. The site will gradually contain more information as clinical trial sponsors and EU/EEA regulators use it to initiate and oversee clinical trials in the EU and EEA. Information on individual clinical trials initiated in the EU and EEA before 31 January 2022 can be found in the European Union Clinical Trials Register.

The Clinical Trials Information System with records registered since 31 January 2022 can be searched from here. The CTIS database includes 147 records (13 April 2023).

For records prior to 31 January 2022 search the EU CTR.
