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   43865   clinical trials with a EudraCT protocol, of which   7286   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
    The objective of the study is to evaluate the efficacy and safety of Dimethyl Fumarate (BG00012) and Peginterferon Beta-1a (BIIB017), both compared with placebo, in paediatric subjects with relapsing-remitting multiple sclerosis (RRMS).
    Protection of trial subjects
    Written informed consent was obtained from each subject or subject’s legally authorized representative (e.g., legal guardian), as applicable, prior to evaluations performed for eligibility. Subjects or the subject’s legally authorized representative were given adequate time to review the information in the informed consent/assent and were allowed to ask, and have answered, questions concerning all portions of the conduct of the study.

    Time to First Relapse [1]
    End point description
    A clinical relapse is defined as new or recurrent neurological symptoms, not associated with fever, lasting for at least 24 hours, and followed by a period of 30 days of stability or improvement. Time to First Relapse is estimated by Kaplan Mayer method. "99999" signifies data is not available as no participant in this arm group had a relapse. ITT population included all subjects who were randomised and received at least 1 dose of study treatment (BG00012, BIIB017, or placebo). The overall number of subjects analysed signifies the number of subjects with relapse.

    Annualized Relapse Rate
    End point description
    A clinical relapse was defined as new or recurrent neurological symptoms, not associated with fever, lasting for at least 24 hours, and followed by a period of 30 days of stability or improvement. The relapse rate for an individual participant was calculated as the number of relapses for that participant divided by the number of participant-years followed. The ARR for each enrolment group was calculated as the total number of relapses experienced in the group divided by the total number of participant-years on the study. An unadjusted relapse rate is reported. ITT population included all subjects who were randomised and received at least 1 dose of study treatment (BG00012, BIIB017, or placebo).

    Limitations and caveats

    Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
    The study was terminated because of long-term difficulties in fulfilling the enrolment commitments and changes in paediatric MS landscape which no longer support placebo-controlled trials. Decision to stop study was not based on safety concerns.
