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   43871   clinical trials with a EudraCT protocol, of which   7290   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)
    Proportion of subjects achieving a response starting at Week 20 through Week 32 (inclusive) who receive rusfertide compared to placebo. A response is defined as absence of phlebotomy eligibility. Phlebotomy eligibility is defined as either:
    • a confirmed hematocrit =45% and that is at least 3% higher than the
    baseline hematocrit (value immediately prior to randomization at Week
    0); or
    • a hematocrit =48%.
    Percentuale di soggetti che ottengono una risposta dalla settimana 20 alla settimana 32 (inclusa) che ricevono rusfertide rispetto al placebo. Una risposta è definita come assenza di ammissibilità alla flebotomia. L'idoneità alla flebotomia è definita come:
    • un ematocrito confermato =45% e che sia almeno il 3% superiore all' ematocrito basale (valore immediatamente prima della randomizzazione alla settimana0); o
    • un ematocrito =48%.
