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 submitted to the National Competent Authorities (NCAs) of the European Union (EU)/European Economic Area (EEA) from 1 May 2004 until 30 January 2023 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).

Any EU/EEA trial with a foreseen Last patient last visit* after 30 January 2025 is required to transition to the Clinical Trials Information System to comply with Regulation (EU) 536/2014. This needs to be done as soon as possible, since this deadline includes the time necessary for completion of the Member State(s) procedure, which can take up to 3 months. More information here.

If your trial is expected to continue after 30 January 2025: see CTIS: how to get started and how to transition a trial. In case of a multi-country trial, sponsors should ensure the harmonisation of their clinical trial under the Directive through EudraCT, prior to transitioning their trial to CTIS: see Guidance for the Transition of clinical trials.

*This applies to all trials having at least one active site in the EU/EEA ('Active site' in the context of transition trials means that the last visit of the last subject, or other trial-specific interventions with the subject specified in the protocol) as well as to any EudraCT trial for which an additional member state application needs to be submitted.

As of 31 January 2023, all initial clinical trial applications in the European Union (EU)/European Economic Area (EEA) must be submitted through the Clinical Trials Information System. As per EudraCT step-by-step guide, the use of the EudraCT database is now limited to:

• the performance of amendments to EU/EEA Clinical Trial Applications for which the initial submission was done before 31 January 2023, for all trials foreseen to complete before 31 January 2025
• 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 update of EudraCT trial statuses by National Competent Authorities, for all trials foreseen to complete before 31 January 2025
• the submission of results of EudraCT trials by sponsors

Clinical Trial Application recommendation: sponsors are recommended to include a functional contact point in section B.5.6 of the Clinical Trial Application/third country file, rather than details of one "person", which would require more frequent updates.

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

What's New

Sponsors of EU/EEA EudraCT trials that are expected to continue after 30 January 2025 are required to transition those trials to the CTIS at their earliest convenience. It's important to be aware that the timeframe for the Member State(s) procedure, which can take up to 3 months, is part of the provided deadline. To know how to transition your trial, see CTIS: how to get started and how to transition a trial.

For questions, refer to Contact us.

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.

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.
