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.2 Objective of the trial
    E.2.1Main objective of the trial
    To evaluate the efficacy of two dosage regimens of palovarotene compared with placebo in preventing new osteochondromas (OCs) in subjects with multiple osteochondromas (MO) due to exostosin 1 (Ext1) or exostosin 2 (Ext2) mutations.
    Evaluar la eficacia de dos pautas posológicas de palovaroteno en comparación con placebo para la prevención de la aparición de osteocondromas (OC) nuevos en sujetos con osteocondromas múltiples (OM) debido a mutaciones de la exostosina 1 (Ext1) o la exostosina 2 (Ext2).
    E.2.2Secondary objectives of the trial
    To compare the following effects of palovarotene with placebo:
    - The volume of osteochondromas (OCs) as assessed by magnetic resonance imaging (MRI).
    - The proportion of subjects with no new OCs.
    - The rate of new or worsening skeletal deformities.
    - The rate of MO-related surgeries.

    Additional secondary objectives:
    - Overall palovarotene safety
    - The pharmacokinetics of palovarotene at steady state
    - The palatability of drug product when sprinkled onto specific foods.

    Exploratory Objective: To compare the following effects of palovarotene with placebo:
