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   43801   clinical trials with a EudraCT protocol, of which   7259   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.

    E.5 End points
    E.5.1Primary end point(s)
    The primary endpoint is the set of antibodies most frequently bound to RBCs in subjects experiencing clinically significant intravascular hemolysis. The presumptive hemolysis cases will be adjudicated by an independent Adjudication Committee to determine if the hemolysis represents clinically significant intravascular hemolysis. Most frequent antibodies are defined as those antibodies that are identified at day 3 as binding specific red cell antigens (determined using an antigen panel) in at least 4 subjects (out of 10 with clinically significant hemolysis).
    E.5.1.1Timepoint(s) of evaluation of this end point
    E.5.2Secondary end point(s)
    Subjects with a platelet response (PR) defined as subjects having a platelet count increases at least once to ≥ 50 x 109/L within 6 days after the first infusion (i.e., up to and including Day 7).
    E.5.2.1Timepoint(s) of evaluation of this end point
