All Clinical Trials of Investigational Medicinal Products which fall under the Medicines for Human Use (Clinical Trials) Regulations 2004, must be registered on the EudraCT database.  The database has been established to provide an overview of all clinical trials in the EC and improve communications between competent authorities in member states (such as the MHRA).

When registered, each trial is issued with a unique EudraCT number which identifies the protocol and trial throughout its lifespan. The number must be quoted on ethics approval and clinical trials authorisation forms.

To obtain a EudraCT number please start by applying for a security code via the EudraCT website.  Please access the website  for further information.
