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   44335   clinical trials with a EudraCT protocol, of which   7366   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.

    Substudy – Vaccination Response
    Sites may collect additional blood samples for additional/optional/future vaccination research. Such research may include (but not limited to) the following:
    1. Humoral (serum) responses to vaccinations received during the study
    2. Cellular (peripheral blood mononuclear cells [PBMCs]) responses to vaccinations received during the study
    Postvaccination samples will be collected at the visits identified in the Summary of Activities only from participants who took part in the vaccination substudy during ARGX-113-2009.
    Data obtained from this substudy will not be included in the clinical database; the results may be described in a separate report.
    E.3Principal inclusion criteria
    1. Has completed the week 36 visit of ARGX-113-2009
    2. Is capable of providing signed informed consent and complying with protocol requirements
    3. Agrees to use contraceptive measures consistent with local regulations and the following:
    a. Male participants: An acceptable method of contraception is a condom. All nonsterilized male participants must use this method from signing of the ICF until the date of the last dose of IMP.
    b. Women of childbearing potential must have a negative urine pregnancy test at baseline before receiving IMP. WOCBP must use one of the contraception methods described in the protocol from signing the ICF until the last dose of IMP
    E.4Principal exclusion criteria
    1. Clinically significant disease, recent major surgery (within 3 months of baseline), or intention to have surgery during the study; or any other medical condition that, in the investigator’s opinion would confound the results of the study or put the participant at undue risk
    2. Known hypersensitivity to IMP or 1 of its excipients
