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   44338   clinical trials with a EudraCT protocol, of which   7368   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 ).

    General information about the trial
    Main objective of the trial
    To evaluate the safety and tolerability of bimekizumab (UCB4940) as an add-on therapy to certolizumab pegol (CZP) and background conventional disease-modifying anti-rheumatic drugs (DMARDs) compared to placebo plus CZP treatment and background conventional DMARDs and to evaluate the efficacy of bimekizumab as an add-on therapy to CZP and background conventional DMARDs compared to placebo plus CZP treatment and background conventional DMARDs at Week 20
