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   43881   clinical trials with a EudraCT protocol, of which   7295   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.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The study is designed to facilitate the selection of a suitable dose range of NBI-921352 for use in
    subsequent efficacy and safety studies in adult subjects with FOS. The study objectives are as
    follows:
    • To assess the safety and tolerability of NBI-921352 in adults with FOS taking
    concomitant background ASMs.
    • To characterize the PK and PK/pharmacodynamic (PD) relationship of NBI-921352
    and determine the effect of NBI-921352 on plasma levels of background ASMs.
    • To assess the efficacy of NBI-921352 on FOS frequency and quality of life in adults
    with FOS taking concomitant background ASMs.
    E.2.2Secondary objectives of the trial
    Not applicable
    E.2.3Trial contains a sub-study No
