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.

Requests will need to be made using the EMA Service desk portal. If you are already registered, open your request here:

If you are not registered, register using the EMA Service desk portal:

This is not a new process but is now extended to the registration of substances for clinical trials.
Note that this process can take 4 working days, so users need to take the SLA into consideration when planning the submission of their applications.
