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   43851   clinical trials with a EudraCT protocol, of which   7283   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.

    7. History of any AIDS-defining illness (category C., CDC, 1993) or any of the following conditions: extrapulmonary Pneumocystis carinii disease; multi-dermatomal Herpes zoster (≥ 10 lesions in a non-contiguous site); American trypanosomiasis (Chagas disease) of the CNS; Penicillium marneffii disease; visceral leishmaniasis; non-Hodgkin’s lymphoma of any cell-type; Hodgkin’s lymphoma; bartonellosis; microsporidiosis (> 1 month’s duration); nocardiosis; invasive aspergillosis; or Rhodococcus equi disease.

    12. Pregnancy (for women of childbearing potential, a negative pregnancy test, urine or serum, is required within 14 days prior to randomization).
    13. Breastfeeding.
    E.5 End points
    E.5.1Primary end point(s)
    The primary endpoint will be mean change in CD4+ T lymphocyte count from baseline (average of two pre-randomization counts) to 32 weeks in the three study groups.
