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.

    General information about the trial
    Main objective of the trial
    • To evaluate the safety and reactogenicity following intramuscular (IM) administration of RSVPreF3 OA investigational vaccine up to 1 month post-Dose 3, for all participants. • To evaluate the humoral immune response following IM administration of RSVPreF3 OA investigational vaccine up to 1 month post-Dose 3, for participants vaccinated with 2 doses of RSVPreF3 OA investigational vaccine in the parent study.
    Protection of trial subjects
    The subjects were observed closely for at least 30 minutes following the administration of the vaccines, with appropriate medical treatment readily available in case of anaphylaxis.

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    04 Nov 2020
    The protocol is amended to address the comments from the United States Food and Drug Administration (US FDA). Specifically, instructions to delay enrolment or vaccination of participants with symptoms suggestive of Coronavirus Disease 2019 (COVID-19) infection or with known COVID-19 positive contacts have been updated. In addition, the requirement to obtain written approval from the Sponsor for a participant to receive a vaccine as part of mass vaccination for an unforeseen public health threat (e.g., pandemic) if the vaccine to be used according to the local governmental recommendations has been amended. Other changes have been made to align the protocol with the parent RSV OA=ADJ-002 study and other phase 3 studies in the project.

    Interruptions (globally)
    Were there any global interruptions to the trial? No
