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   44346   clinical trials with a EudraCT protocol, of which   7374   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.

    General information about the trial
    Main objective of the trial
    • To evaluate whether stem cell transplantation (SCT) from a matched sibling donor (MSD) is equivalent to a matched unrelated donor (MUD) in second complete remission (CR2) (see statistics part). • To evaluate whether “FLAMSA” increases survival as compared to a survival rate estimated from historical data (studies AML-BFM and Relapsed AML 2001/1) in children suffering from refractory AML or relapsed AML responding poorly to reinduction therapy. • To evaluate whether HSCT from haploidentical donors for children having no matched donor increases survival as compared to a survival rate estimated from historical data (studies AML-BFM and Relapsed AML 2001/1) in children suffering from refractory AML or relapsed AML.
    Protection of trial subjects
    The clinical trial was conducted in accordance with the ethical principles that have their origins in the Declaration of Helsinki and with the standards of International Conference on Harmonisation (ICH) Good Clinical Practice (GCP).
