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   43845   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.

    General information about the trial
    Main objective of the trial
    The primary objective was to evaluate the evolution of dGEMRIC (delayed Gadolinium-Enhanced Magnetic Resonance Imaging in Cartilage) imaging marker after 6 months of treatment with DROGLICAN® The second objectives included the use of rescue treatments (Paracetamol, tramadol or oral NSAIDs, excluding COX2 inhibitors) and evaluation of safety and tolerability of the treatment.
    Protection of trial subjects
    The clinical trial has been performed according to GCP ICH E6 and the ethical principles that have their origins in the Declaration of Helsinki, last updated in Fortaleza 2013.

    Change of dGEMRIC index after 6 months of DROGLICAN® [1]
    End point description
    Measure of the change of dGEMRIC index (imaging marker) of the cartilage at baseline (T0) and at after 6 months of treatment with DROGLICAN® (T6) for femoral, tibial and patellar cartilage segments (lateral and medial) by Magnetic Resonance Imaging. dGEMRIC index values remained constants along the 6 months-treatment period and no statistically significant changes were found for any of the compartments.
    End point type
    Primary
    End point timeframe
    From baseline (T0) to 6 months after treatment with DROGLICAN® (T6).
    Notes
    [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point.
    Justification: Since it was a single-arm study, the statistical analysis performed was descriptive and comparative with respect to baseline. The evolution of dGMERIC index between baseline and 6 months was evaluated using parametric t-test (within treatment differences).
