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   43858   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.

    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    Investigation of the immune response following immunization with Immucothel/Alhydrogel with or without tetanus. Per efficacy endpoint, the following parameters will be explored:
    (a) Response size;
    (b) Inter-individual variability of the response;
    (c) Time course of the response.
    Moreover, for each efficacy endpoint, it will be confirmed that a simultaneous administration of tetanus toxoid does not interfere (or only minimally) with the KLH response. This is valuable information to support simultaneous KLH/tetanus toxoid immunizations in the future intervention trial targeting OX40/OX40L. The data generated in the current study will allow selection of the most robust readout measures for quantification of the Immucothel/Alhydrogel-induced immune response in the future OX40/OX40L study and allow for a power analysis of studies using this model.

    E.3Principal inclusion criteria
    Eligible subjects must meet all of the following inclusion criteria at screening:
    1. Healthy male subjects, 18 to 45 years of age (inclusive). The health status is verified by absence of evidence of any clinical significant active or uncontrolled chronic disease following a detailed medical history and a complete physical examination including vital signs, laboratory measurements and 12-lead ECG;
    2. Body mass index (BMI) between 18 and 30 kg/m2, inclusive, and with a minimum bodyweight of 50 kg;
    3. Previous immunization with tetanus toxoid as reported by the subject;

    E.4Principal exclusion criteria
    Eligible subjects must meet none of the following exclusion criteria at screening:
    1. Any disease associated with immune system impairment, including auto-immune diseases, HIV, any confirmed history of severe allergic reaction and transplantation patients;
    2. Known infection requiring antibiotic therapy within the last three months prior to the study
    3. Previous known exposure to Immucothel® or KLH;

    8. Participation in an investigational drug or device study within 3 months prior to screening or more than 4 times a year;
    9. Previous participation in an investigational drug or device study involving the dosing of a biological targeted at any immune pathway within one year prior to screening;
    10. Loss or donation of blood over 500 mL within three months prior to screening;
    11. Any (medical) condition that would, in the opinion of the investigator, potentially compromise the safety or compliance of the subject or may preclude the subjects’ successful completion of the clinical trial.
    12. History of Schistosomiasis (infection with Schistosoma parasite).
    13. History or current nicotine use in access of 5 cigarettes per day, or unable not to smoke during the course of the study, defined as between the screening visit and the final visit.
    14. Tetanus toxoid immunization within the last 10 years before study participation
    E.5 End points
    E.5.1Primary end point(s)
    • KLH-specific and tetanus toxoid-specific IgG and IgM titers (ELISA);
    • Ex vivo PBMC activation upon both an Immucothel® and tetanus toxoid challenge of isolated PBMCs. Response quantification by proliferation markers (for example by CellTrace Violet or BrdU) and possibly cytokine release (e.g. IL-2, IL-6, IL10, IL-17 and IFN);
    • Ex vivo whole blood activation upon both an Immucothel® and tetanus toxoid challenge. Response quantification by flow cytometric analysis of T cell activation markers;
    • Erythema and swelling at the sites of intradermal KLH (Delayed Type Hypersensitivity [DTH] upon intradermal injection of 1 μg Immucothel® in 10L, on the flexor aspect of the forearm).
