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   43850   clinical trials with a EudraCT protocol, of which   7282   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.

    5. RhD-positive serology.
    6. Previous treatment and response to first line therapy for ITP (corticosteroids, anti-D or IVIg), with response being defined as an increase in platelet count to
    ≥ 50,000/mm3.
    7. female and of child-bearing potential, subject has a negative pregnancy test at screening.
    8. If subject is a female of child-bearing potential, subject agrees to use a medically accepted form of contraception from the time of enrolment to completion of all follow-up trial visits.
    E.4Principal exclusion criteria
    1. Known clinical picture suggestive of other causes of thrombocytopenia, especially systemic lupus erythematosus, antiphospholipid syndrome, Evans syndrome, immunodeficiency states, lymphoproliferative disorders, liver disease, ingestion of drugs such as quinidine/quinine, heparin and sulfonamides and hereditary thrombocytopenia confirmed by relevant laboratory findings.
    2. Suspected infection with HIV, hepatitis C, H. pylori unless corresponding laboratory tests are negative.
    3. Clinical splenomegaly (the spleen should not be palpable at more than 1 finger breadth below the costal margin).

    7. History of immune haemolytic anaemia.
    8. Underlying haemolytic condition (e.g. reticulocyte count > 3%).
    9. Planned surgery during the trial period.
    10. Haemoglobin pre-dose value lower than 2g/dL below the lower limit of the laboratory normal range for gender and age.
    11. History of splenectomy.

    13. Received investigational agent within 90 days prior to enrolment.
    14. Positive DAT (direct Coombs-test) at screening unless subject has received treatment with anti-D products within 3 months prior to screening with prior negative DAT.
    15. Known non-responders to most recent anti-D treatment (despite any initial response to treatment).
    16. Any other current treatment for ITP except corticosteroids at doses up to 20 mg/day. (Acceptable if the dose has been constant for 2 weeks or more before trial drug administration).

    21. History of thrombosis or known thrombophilia.
    22. Diseases other than ITP that may influence the result of the trial as judged by the Investigator.
    23. Creatinine, alanine aminotransferase (ALT), alkaline phosphatase (ALP), and Albumin 25% or more outside normal range value (according to the local laboratory) at pre-dose visit.
