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.
