Searching for clinical trials
This website provides information on individual clinical trials in the European Union and European Economic Area since its launch on 31 January 2022. It 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 European Union and the European Economic Area before 31 January 2022 can be found in the European Union Clinical Trials Register.
End of transition period to the Clinical Trials Regulation
All clinical trials in the European Union (EU) that are ongoing after 30 January 2025 must comply with the Clinical Trials Regulation (CTR) and should have been submitted to the Clinical Trials Information System (CTIS).
Transparency in CTIS
The revised CTIS transparency rules became applicable on 18 June 2024, with the launch of a new version of the CTIS website. Support materials and more information are available under Transparency: Questions and Answers.
