Welcome to the EudraCT public home page

EudraCT (European Union Drug Regulating Authorities Clinical Trials Database) is the European database for all interventional clinical trials on medicinal products authorized in the European Union (EEA) and outside the EU/EEA if they are part of a Paediatric Investigation Plan (PIP) from 1 May 2004 onwards. It has been established in accordance with Directive 2001/20/EC. Protocol and results information on interventional clinical trials are made publicly available through the European Union Clinical Trials Register since September 2011.

In order to navigate through the present website, it is strongly encouraged to refer to the EudraCT user manual.

Sponsors’ representatives are recommended to prepare and post clinical trials results as explained in the Tutorials on posting results webpage.

What's New

Sponsors of clinical trials on COVID-19 are requested to include the term "COVID-19" in the title of their trial (section A.3 of the CTA). Sponsors are also reminded of the importance of timely reporting of SAEs (Serious Adverse Events) and of SUSARs (Suspected Unexpected Serious Adverse Reactions) to the competent authorities, in order to protect the safety of the participants. In addition, we encourage sponsors of COVID-19 trials to post the relevant results as soon as it is feasible, also before the deadline.


We would like to make Sponsors aware there is an issue with the assignment of primary users of trials.
Our IT is working to fix it as soon as possible. We thank you very much for your patience and we apologise for the inconvenience.

Sponsors of trials that are "prematurely ended" can now post results in EudraCT as a pdf document.

  • For trials that were approved but never started, sponsors are required to state the reasons for the premature interruption in the pdf document
  • For trials that started and terminated early, sponsors are required to state the reasons for the early interruption, together with any partial result, if available, in the pdf document

Please refer to the Tutorials on posting results in order to know how to become a primary user for your trial and post the pdf document. After the document has been uploaded, kindly click on "post results" on the top right corner. The document will be published in EU CTR after 2 weeks from posting date (except for phase 1 trials in adults, that are not publicly available, see FAQs).


The EudraCT website will be unavailable to users today between 6 pm and 8 pm (CET). We apologise for this inconvenience and we thank you very much for your patience.
