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   43865   clinical trials with a EudraCT protocol, of which   7286   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 ).

    General information about the trial
    Main objective of the trial
    Primary Objective: 1. To evaluate geometric mean titer (GMT) and seroconversion rate to varicella zoster virus (VZV) after intramuscular (IM) and subcutaneous (SC) injection of GlaxoSmithKline Biologicals' (GSK’s) combined measles-mumps-rubella-varicella (MeMuRu-OKA) vaccine. Secondary Objectives: 1. To evaluate the cell-mediated immunity (CMI) to varicella and measles after IM and SC injection of GSK’s MeMuRu-OKA vaccine. 2. To quantify the immediate vaccination pain after IM and SC injection of GSK’s MeMuRu-OKA vaccine. 3. To evaluate GMT and seroconversion rate to measles, mumps, and rubella, after IM and SC injection of GSK’s MeMuRu-OKA vaccine. 4. To evaluate incidence, nature and severity of local, general, and serious adverse events after IM and SC injection of GSK’s MeMuRu-OKA vaccine.
    Protection of trial subjects
    The subjects were observed closely for at least 30 minutes, with appropriate medical treatment readily available in case of a rare anaphylactic reaction following vaccine administration.

    An unsolicited AE was any AE reported in addition to those solicited during the clinical study. Also, any “solicited” AE with onset outside the specified period of follow-up for solicited AEs was reported as an unsolicited AE. Any = any unsolicited AE irrespective of its intensity grade and relationship to vaccination. Grade 3 AE = AE that prevented normal activity.
