Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   43865   clinical trials with a EudraCT protocol, of which   7286   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).

    At the end of the treatment, the study doctor may continue to give the subject AG10 as an extension of this study, until AG10 is commercially available for the treatment of subjects with symptomatic Transthyretin Amyloid Cardiomyopathy, unless the study doctor believes it no longer in your best interests, or unless the Sponsor terminates development of the AG10 for the treatment of symptomatic ATTR-CM in your country.
    al termine del trattamento, il medico dello studio può continuare a somministrare AG10 al soggetto come estensioen di questo studio, fino a quando AG10 sarà commercialmente disponibile per il trattamento di soggetti con cardiomiopatia amiloide transtiretina sintomatica, a meno che il medico dello studio non ritenga che sia più nel vostro interesse o lo sponsor termini lo sviluppo di AG10 per il trattamento dell'ATTR-CM nel vostro paese
