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   44334   clinical trials with a EudraCT protocol, of which   7366   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.

    b) Change in DAS28-hsCRP from baseline to Weeks 4, 8, and 12.
    c) Successful composite clinical response (Yes/No) at Weeks 4 and 8 defined as achieving clinical response according to the criteria for ACR20.
    E.5.2.1Timepoint(s) of evaluation of this end point
    a)Difference in mean change from baseline in each RAMRIS score,in patients assessed after 12 weeks of treat. with MBS2320 compared to placebo:
    1 as though no increase in any RA medication and no treat. discontinuation or interruption for any reason
    2 irrespective of treat. discontinuation or interruption due to tolerability issues or lack of efficacy, and as though no increase in any other RA medication
    b) Change in DAS28-hsCRP as dependent variable from baseline will be measured at week 4, 8 and 12 using a mixed model for repeated measures
    c) Difference in % of patients with a previous inadequate resp. to MTX alone,with intra-articular synovitis on baseline MRI, who would have successful comp. clinical resp. after each of 4 and 8 weeks of treatment with MBS2320 compared to placebo
