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   43861   clinical trials with a EudraCT protocol, of which   7284   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 assess the reduction of absenteeism among healthcare professionals with direct patient contacts during the pandemic phase of COVID-19
    Protection of trial subjects
    The trial was conducted in accordance with GCP ICH-E6(R2) , GCP-V, EU Directives 2005/28/EC and 2001/20/EC, the ethical principles set forth in the Declaration of Helsinki, and local regulatory requirements. Each participating investigator/institution was responsible for assuring that the protocol, the associated informed consent documents, and trial-related documents were reviewed and approved by a local independent ethics committee (IEC) prior to the implementation of the protocol. Prior to any trial-related screening procedures being performed, informed consent was obtained from each subject before enrollment in the trial. The procedures to explain the meaning of informed consent to the subject to obtain their consent complied with current IEC and legal requirements, the ICH-GCP Guidelines and the ethical principles in the Declaration of Helsinki. Consent for processing personal data was also obtained from the caretaker of the study subject. Subjects were informed that their participation was voluntary and that they had the right to withdraw from the trial at any time and for any reason without any disadvantages. Only subjects that met all inclusion criteria and none of the exclusion criteria were enrolled in the study.

    Blinding implementation details
    The vaccine preparation was done by designated unblinded personnel who did not participate in any of the clinical trial evaluations. The administration was done by blinded trial staff. The unblinded pharmacist, or other qualified site staff, prepared the vaccine out of view of the subject and the site staff who administered the vaccine. The syringes were masked with a colored translucent wrapping before administration.

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    02 Jun 2020
    Relevant changes introduced in protocol Version 4.0 dated 02-Jun-2020 compared with Version 3.0 (first protocol version under which subjects were enrolled, dated 06-May-2020) were: • The inclusion criterion “hospital personnel with expected high SARS-CoV-2 exposure” was changed to “healthcare professionals taking care of potentially SARS-CoV-2-infected patients”. • The exclusion criterion “Participation of subject in another study within 30 days before screening and during this study” was changed to “Participation of subject in another interventional study within 30 days before screening”. • The exclusion criterion “employed to the hospital <22 hours per week” was changed to “employment of less than 50% of a full-time equivalent”. • A per-protocol analysis set was defined and added for the sensitivity analysis of the primary endpoint.
    11 Aug 2020
    Relevant changes introduced in Version 5.0 dated 11-Aug-2020 compared with Version 4.0 included: • Added that subjects who dropped out before IMP administration would be replaced • Clarified that documentation of body temperature, adverse events, and concomitant medications in a daily diary was optional

    Interruptions (globally)

    Were there any global interruptions to the trial? No

    Limitations and caveats

    Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
    Due to an insufficient recruitment rate and premature termination of the trial, only 59 of the originally planned 1200 subjects were anylzed. Therefore, no meaningful conclusions can be drawn for the efficacy of VPM1002 vaccination.
