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   37720   clinical trials with a EudraCT protocol, of which   6181   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.2.1Main objective of the trial
    To evaluate the efficacy of MK-8228 in the prevention of clinically significant CMV infection through Week 24 (~6 months) post-transplant following administration of MK-8228 or placebo.
    E.2.2Secondary objectives of the trial
    1) To evaluate the safety and tolerability of MK-8228.
    2) To evaluate the efficacy of MK-8228 in the prevention of clinically significant CMV infection through Week 14 (~100 days) post-transplant.
    3) To evaluate the efficacy of MK-8228 as assessed by time to onset of clinically significant CMV infection through Week 24 (~6 months) post-transplant.
    4) To determine the incidence of CMV disease through Week 14 post -transplant and Week 24 post-transplant.
    5) To assess the incidence of PET for CMV viremia through Week 14 post-transplant and Week 24 post-transplant.
    6) To assess the time to initiation of PET for CMV viremia through Week 14 post-transplant and Week 24 post-transplant.
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    Merck will conduct Future Biomedical Research on DNA (blood) specimens collected during this clinical trial. Such research is for biomarker testing to address emergent questions not described elsewhere in the protocol (as part of the main trial) and will only be conducted on specimens from appropriately consented subjects. The objective of collecting specimens for Future Biomedical Research is to explore and identify biomarkers that inform the scientific understanding of diseases and/or their therapeutic treatments. The overarching goal is to use such information to develop safer, more effective drugs, and/or to ensure that subjects receive the correct dose of the correct drug at the correct time.

    E.5 End points
    E.5.1Primary end point(s)
    The primary efficacy endpoint of the study is the proportion of subjects with clinically significant CMV infection through Week 24 (~6 months) post-transplant, defined as the occurrence of either one of the following outcomes:
    •onset of CMV end-organ disease
    OR
    •initiation of anti-CMV PET based on documented CMV viremia (as measured by the central laboratory) and the clinical condition of the subject. Initiation of PET in this study refers to the practice of initiating therapy with the following approved anti-CMV agents when active CMV viral replication is documented: ganciclovir, valganciclovir, foscarnet, and/or cidofovir.
