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   43974   clinical trials with a EudraCT protocol, of which   7311   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.2 Objective of the trial
    E.2.1Main objective of the trial
    To compare the efficacy of pacritinib with that of best available therapy (BAT) in patients with primary myelofibrosis (PMF), post-polycythemia vera myelofibrosis (PPV-MF), or post-essential thrombocythemia myelofibrosis (PET-MF); the efficacy measure for this analysis is the proportion of patients achieving a ≥ 35% reduction in spleen volume from baseline to Week 24, as measured by magnetic resonance imaging (MRI) or computed tomography (CT) scan.
    E.2.2Secondary objectives of the trial
    The key secondary objective is the proportion of patients with ≥ 50% reduction in total symptom score from baseline to Week 24 on the MPN-SAF TSS 2.0.

    Other secondary objectives are to compare pacritinib with BAT with respect to:
    1. Proportion of patients with baseline platelet count < 100,000/μL achieving ≥ 35% reduction in spleen volume from baseline to Week 24 as measured by MRI or CT scan
    2. Proportion of patients with baseline platelet count < 100,000/μL achieving ≥ 50% reduction in TSS from baseline to Week 24
    3. Proportion of patients with baseline platelet count < 50,000/μL achieving ≥ 35% reduction in spleen volume from baseline to Week 24 as measured by MRI or CT scan
    4. Proportion of patients with baseline platelet count < 50,000/μL achieving ≥ 50% reduction in TSS from baseline to Week 24
