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   36111   clinical trials with a EudraCT protocol, of which   5936   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).
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.1.3Condition being studied is a rare disease Yes
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective of the study is to demonstrate a reduction in intravascular hemolysis by REGN3918 over 26 weeks of treatment in patients with active PNH who are treatment naive to complement inhibitor therapy or have not recently received complement inhibitor therapy
    E.2.2Secondary objectives of the trial
    The secondary objectives of the study are:
    •To evaluate the safety and tolerability of REGN3918.
    •To evaluate the effect of REGN3918 on parameters of intravascular hemolysis
    •To assess the concentrations of total REGN3918 in serum.
    •To evaluate the incidence of treatment emergent anti drug antibodies to REGN3918.
    •To evaluate the effect of REGN3918 on patient reported outcomes (PROs) measuring fatigue and health related quality of life
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    There are optional future biomedical research and pharmacogenomic analysis sub-studies . Subjects will be required to sign separate sub-study ICFs before collection of samples. There is no separate protocol.
    The purpose of the genomic analyses is to identify genomic associations with clinical or biomarker response, other clinical outcome measures and possible AEs. In addition, associations between genomic variants and prognosis or progression of as well as other diseases may also be studied.
    In addition, PROs such as fatigue or quality of life in a subset of patients at participating sites will be assessed (ie, sub study).
    There will not be separate sub-study protocols.
