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   7312   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
    In this randomized study the primary objective is to prove the superiority of combination treatment RTX with cyclophosphamide to achieve a state of MRA in AAV patients as compared to RTX alone. The primary objective is to assess the time to an ANCA negative test.
    E.2.2Secondary objectives of the trial
    Secondary objectives are:
    - time to ANCA return
    - duration of B-cell depletion
    - composition of the memory B-cell and plasma cell compartment before and after treatment
    - to investigate whether MRA is associated with disease flares
    - to investigate whether MRA is associated with (a shorter) time to a disease flares
    - to investigate whether the presence or absence of MRA after RTX can guide a personalized treatment
    - to assess the safety parameters of each treatment arm including adverse events according to WHO toxicity criteria, time to immune reconstitution and recording of infectious events

    E.5 End points
    E.5.1Primary end point(s)

    E.5.2Secondary end point(s)
    - assess the time to ANCA return defined as seroconversion to positive on at least 2 consecutive visits (the time of the first is then representative time of seroconversion) OR a doubling of the ANCA serum levels PR3 or MPO ELISA test compared to a previously achieved nadir
    - duration of B-cell depletion defined as time taken to detect a repopulation of B-cells above the detection limit of standard flowcytometry (i.e. > 1x106 cells/L)
    - composition of the memory B-cell and plasma cell compartment before and after treatment using standard and high-sensitivity flowcytometry
    - to investigate whether MRA is associated with disease flares where degrees of MRA are defined as seroconversion of ANCA to negative with or without B-cell depletion
    - to investigate whether MRA is associated with (a shorter) time to a disease flares
    - to assess the safety parameters of each treatment arm including adverse events according to WHO toxicity criteria and recording of infectious events
