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   43861   clinical trials with a EudraCT protocol, of which   7284   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.

    - To assess the ability of blood C-reactive protein (CRP) and fecal calprotectin to predict short term relapse in the three groups.
    - To assess time spent in clinical remission in the three groups.
    - To assess the rate of treatment failure in the three study groups.
    - To assess the time to treatment failure in the three study groups.
    - To assess progression of bowel damage in the three groups.
    - To assess the safety and efficacy of infliximab retreatment in the antimetabolites group.
    - To assess safety in the three study groups.
    - To assess the health related quality of life in the three study groups.
    - To assess direct and indirect costs in the three study groups.

    E.5 End points
    E.5.1Primary end point(s)
    There are two co-primary efficacy end points:

    Relapse rate at 2 years, relapse being defined by either one of the following events:
    - A CDAI>250 at any visit or between 150 and 250 with an increase of at least 70 points, over two consecutive visits one week apart associated with a CRP > 5 mg/l or a fecal calprotectin > 250 microg/g
    - A new opening fistula, perianal or entero-cutaneous.
    - An intra-abdominal abcess (size of at least 3 cm) or perianal abcess (size of at least 2 cm)
    - An episode of intestinal obstruction due to Crohn’s lesions confirmed by medical imaging and requiring hospitalisation (also considered as treatment failure, see below)

    Mean restricted time spent in remission
    This time will be computed in all patients, from baseline (CDAI <150 and with absence of fistula drainage) until relapse, as defined above, within the 2 first years. First and subsequent remissions will be summed up within the two first years.

    - To assess time spent inclinical remission in the three groups.
    - To assess the rate of treatment failure in the three study groups.
    - To assess the time to treatment failure in the three study groups.
    - To assess progression of bowel damage in the three groups.

    - To assess safety in the three study groups.
    - To assess the health related quality of life in the three study groups.
    - To assess direct and indirect costs in the three study groups.
    - To assess evolution of blood CRP and fecal calprotectin in the three study groups.

    The treatment of patients reaching the end of the trial would be discussed between the patient and clinical team, and the process managed according in line with current best clinical practice.
