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   44020   clinical trials with a EudraCT protocol, of which   7318   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 ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    F.5 Plans for treatment or care after the subject has ended the participation in the trial (if it is different from the expected normal treatment of that condition)
    If selumetinib is approved locally and reimbursed for use in paediatric patients with NF1 who have symptomatic, inoperable PN, participants should be switched to the commercial supply at the end of the study.
    However, if the participant is unable to access the commercial supply and they are still receiving clinical benefit, AstraZeneca and the Investigator will discuss how the participant could continue to receive selumetinib if he/she is benefiting from treatment.
    Se selumetinib è approvato a livello locale e rimborsato per l'uso pediatrico in pazienti con NF1 che hanno PN sintomatico e inoperabile, i partecipanti alla fine dello studio dovrebbe passare alla fornitura commerciale.
    Tuttavia, se il partecipante non è in grado di accedere alla fornitura commerciale e sta ancora ricevendo benefici clinici, AstraZeneca e lo sperimentatore discuterà come il partecipante potrebbe continuare a ricevere selumetinib, se sta beneficiando del trattamento.
