Welcome to the EudraCT public home page

EudraCT (European Union Drug Regulating Authorities Clinical Trials Database) is the database for all interventional clinical trials on medicinal products that were conducted in the European Union (EU)/European Economic Area (EEA) between 1 May 2004 and 30 January 2025 under Directive 2001/20/EC, as well as for all trials conducted outside of the EEA that are part of a Paediatric Investigation Plan (PIP) and/or are conducted under Article 45 or 46 of Regulation (EC) No 1901/2006. Most of the protocol and results information of EudraCT trials is made publicly available through the European Union Clinical Trials Register (see Frequently Asked Questions).

End of transition period to the Clinical Trials Regulation: all clinical trials in the European Union (EU)/European Economic Area (EEA) that are ongoing after 30 January 2025 must comply with the Clinical Trial Regulation (EU) 536/2014 and, therefore, should have been submitted to the Clinical Trials Information System (CTIS).

If your trial is displayed as ‘ongoing’ on the European Union Clinical Trials Register you need to liaise with the relevant National Competent Authority(ies) in order to have this corrected. You cannot update the trial status yourself through logging in EudraCT: more details in question 3 of Frequently Asked Questions

As per EudraCT step-by-step guide, the use of the EudraCT database is now limited to:

• the upload of third country files of trials conducted exclusively outside of the EU/EEA that are part of a Paediatric Investigation Plan (PIP) and/or in scope of Article 46 of the Paediatric Regulation (EC) 1901/2006 (so called “third country files”)
• the submission of results of EudraCT trials by sponsors

Requirement to provide results: sponsors are required to post EudraCT trials' results as per Joint Letter by the European Commission, EMA and HMA

Following the European Commission's Guidance on results postings, the European Medicines Agency and National Competent Authorities sent rounds of notifications in order to remind sponsors of their responsibilities as regards posting clinical trial results in EudraCT.
