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   43881   clinical trials with a EudraCT protocol, of which   7295   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.

    D.8 Information on Placebo
    E. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Plasmodium Falciparum Malaria
    MedDRA Classification
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The main purpose of this study is to assess the safety and effectiveness of two new vaccines against malaria in healthy volunteers.

    The vaccines are two different types of virus which contain genetic information (DNA) from the malaria parasite. This genetic material produces a parasite component named MSP1.
    We will be checking the safety of different doses of one of the vaccines.
    Both viruses are changed so that they are unable to multiply within the body.

    The first vaccine virus is a weakened version of a common cold virus which usually infects chimpanzees and is called an adenovirus. The vaccine is called AdCh63 MSP1.

    The other virus is Modified Vaccinia Ankara Virus, (MVA), which is a safer form of the virus previously widely used for smallpox vaccination. The vaccine is called MVA MSP1.
    The safety of the vaccines will also be assessed during a malaria challenge.
    E.2.2Secondary objectives of the trial
    The secondary objective is to assess markers of the effectiveness of two new vaccines against malaria. We want to test the response of the human immune system to the vaccines. The vaccines help the body make an immune response against the malaria parasite, and so to test the effectiveness of the vaccine we will also expose a small group of volunteers to experimental malaria infection to see if the vaccine combination can prevent or delay malaria developing. We will take regular blood samples to see what effect the vaccines have had on the immune system.

    • Seropositive for hepatitis C virus (antibodies to HCV)
    • Any other significant disease, disorder or finding, which, in the opinion of the Investigator, may either put the volunteer at risk because of participation in the study, or may influence the result of the study, or the volunteer’s ability to participate in the study.
    • Any history of malaria or
    • Travel to a malaria endemic region during the study period or within the previous six months
    • Any clinically significant abnormal finding on screening biochemistry or haematology blood tests or urinalysis
    • Any other finding which in the opinion of the investigators would significantly increase the risk of having an adverse outcome from participating in the protocol.
    E.5 End points
    E.5.1Primary end point(s)
    Primary outcome measures:
    -To assess the safety in healthy volunteers of two new candidate malaria vaccines, AdCh63 MSP1 and MVA MSP1. The safety of AdCh63 MSP1 when administered alone and in combination with MVA MSP1 will be assessed.

    -To assess the safety of the prime-boost blood stage vaccine strategy following malaria sporozoite challenge.

    The specific endpoints for safety and reactogenicity will be actively and passively collected data on adverse events, including laboratory safety data, following vaccination (all groups) and sporozoite challenge (group 2C). The collection and interpretation of adverse event data including severity grading scales are summarised in Section 12 of the clinical trial protocol.
