Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   42891   clinical trials with a EudraCT protocol, of which   7066   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    dose levels when compared to baseline during 12 weeks maintenance dosing in a
    placebo controlled trial in patients with Lennox-Gastaut Syndrome (LGS).
    2. To determine the safety of CLB when administered for up to 18 weeks at three different
    dose levels in patients with LGS.
    E.2.2Secondary objectives of the trial
    1. To determine the efficacy of CLB as determined by responder rates and global
    evaluation of patient symptoms.
    2. To determine population pharmacokinetic (PPK) parameters of CLB and its active
    metabolite N-desmethylclobazam (N-CLB) at steady-state dosing of CLB in patients
    with LGS and to describe sources of inter-patient variability (co-variates) including
    patient demographics, concomitant antiepileptic drug (AED) medications and genotype.
    3. To evaluate the development of tolerance during treatment for up to 12 weeks.
    4. To determine the effect of CLB on behavior utilizing the Child Behavior Checklist
    5. To determine the impact of CLB on behavioral, cognitive and physical/neurologic
    disability through use of the Impact of Childhood Neurologic Disability Scale (ICNDS).
