Joining a clinical trial

If you have found information on a specific clinical trial and are interested in joining a trial, we suggest you contact your healthcare professional for advice.  The European Medicines Agency is not able to provide information related to specific trials.  If you wish to contact the clinical trial sponsor you can find contact information in the trial record that interests you. However, this only applies to trials entered in the system after 10 March 2011.  For trials entered before 10 March 2011, please consult the clinical trial sponsors' contact information PDF document [134kB] document, which is also available on the clinical trial sponsors page. Please note this list is not exhaustive.

If the contact information for a clinical trial sponsor is not in this PDF document, you are advised to contact the sponsor company or organisation directly through the contact information on its corporate website.

Please note that you should not interpret the information on the EU Clinical Trials Register website as a recommendation to use the medicine or to participate in the trial.  The medicine or the clinical trial may not be suitable for you. 

You should consult your healthcare professional or the trial investigator to discuss appropriate treatment options.
