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   41018   clinical trials with a EudraCT protocol, of which   6709   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) .
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

Samples collected within 5 days of screening will be acceptable. If not yet available the assessments should be performed at the time of screening.
    6. Subject has: a) diagnosis of RSV LRT disease OR b) diagnosis of RSV URT disease with high risk of progression to LRTI
    7. Female subjects of childbearing potential (ie fertile, following menarche and until becoming post-menopausal unless permanently sterile) and fertile male subjects must agree to use highly effective contraceptive methods prior to study entry, for the duration of the study participation and for 3 months after the last dose of the study drug.
    8. Female subjects of childbearing potential (exclusing postmenopausal women, sterilized, ovariectomized and hysterectomized women) must have a negative pregnancy test assessed locally at screening
    9. Subject is capable to comprehend the informed consent document and provides a signed and dated Informed Consent Form

    3. Subject is known to be HIV positive
    4. Subject presents evidence of shock requiring ICU monitoring and/or vasopressor treatment
    5. Subject requires or is expected to require invasive mechanical ventilation or intensive non-invasive respiratory support (CPAP, BiPAP, HFOT). Standard oxygen supplementation up to 6l/minute is permitted provided it can be interrupted for the duration of the study drug administration
    6. Subject has been/is being treated with any of the following
    - any investigational antiviral medication or investigational biological within 5 half lives of screening

    - any monoclonal anti-RSV antibodies within 4 months or 5 half lives of screening (whichever is longer)
    - any investigational vaccine after HSCT
    - Aerosolized ribavirin within 3 days of screening or needing to initiate or continue this treatment
    7. Subject is pregnant or breastfeeding
