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   43873   clinical trials with a EudraCT protocol, of which   7293   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.2 Objective of the trial
    E.2.1Main objective of the trial
    To describe the long-term safety profile of mepolizumab in participants with HES who took part in Study 200622.
    E.2.2Secondary objectives of the trial
    Not Applicable
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    Participants are eligible to be included in the study only if all of the following criteria apply:
    Study 200622 requirements
    1. Age 12 years and older participants who were enrolled in Study 200622.
    To be considered for Study 205203, Study 200622 participants must have completed 32-week assessments since randomization:
    (i) Completion of the 32-week treatment period in Study 200622
    OR
    (ii) If the participant was withdrawn from study treatment prematurely during the 200622 study, but continued in the study per protocol(including HES flare related assessments) until 32 weeks from randomization.
    Sex
    2. Male or female
    Female participants:
    A female participant who meets one of the following conditions:
    (i) Not a woman of childbearing potential (WOCBP) as defined in Appendix 5
    OR
    (ii) A WOCBP who agrees to follow the contraceptive guidance in Appendix 5 at least 30 days prior to the first dose of study treatment and until 16 weeks after the last dose of study treatment.

    Positive benefit: risk ratio
    3. The treating physician must confirm a positive benefit/risk ratio. The anticipated clinical benefit from mepolizumab must outweigh any potential safety or tolerability risk in Study 205203.

    Informed consent
    4. Capable of giving signed informed consent as described in Appendix 3 which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.
    E.4Principal exclusion criteria
    Participants are excluded from the study if any of the following criteria apply:
    Medical conditions
    1. Participants with any history of hypersensitivity to any monoclonal antibody (including mepolizumab)
    2. Participants with current malignancy or malignancy that developed during Study 200622.
    NOTE:
    Participants who had localized localized carcinoma (i.e., basal or squamous cell) of the skin which was resected for cure will not be excluded.
    3. Participant who is pregnant or breastfeeding.
    NOTE:
    Participants should not be considered for continued treatment if they plan to become pregnant during the course of treatment with mepolizumab.
    4. Participant who has other clinically significant medical conditions uncontrolled with SoC therapy not associated with HES, e.g., unstable liver disease, uncontrolled cardiovascular disease, ongoing active infectious disease.
    NOTE:
    -Participants with recent parasitic (helminth) infections will be excluded from the study or required to be adequately treated for helminth infections before initiation of mepolizumab.
    5. Participants with QTc >450 msec or QTc > 480 msec in participants with bundle branch block based on local EGC reading
    NOTES:
    -The QTc is the QT interval corrected for heart rate according to Bazett’s formula (QTcB), Fridericia’s formula (QTcF), and/or another method. It is either machine-read or manually over-read.
    - The specific formula used to determine eligibility and discontinuation for an individual participant should be determined prior to initiation of the study. In other words, several different formulas cannot be used to calculate the QTc for an individual participant and then the lowest QTc value used to include or discontinue the participant from the trial.

    6. Liver abnormality/disease:
    - Participants who discontinue study treatment based on liver chemistry stopping
    criteria during Study 200622
    -Current active liver or biliary disease (with the exception of Gilbert’s syndrome
    or asymptomatic gallstones or otherwise stable chronic liver disease per
    investigator assessment).
    NOTE: Stable chronic liver disease should generally be defined by the absence
    of ascites, encephalopathy, coagulopathy, hypoalbuminaemia, oesophageal or
    gastric varices, or persistent jaundice, or cirrhosis.

    Prior/concurrent clinical study experience

    7. Other investigational product/clinical study:
    -Participants who have received treatment with an investigational agent (biologic
    or non-biologic) within the past 30 days or 5 drug half-lives whichever is longer,
    prior to the first dose, other than Study 200622 study treatment. The term “investigational” applies to any drug not approved for sale for the disease/indication to treat in the country in which it is being used or
    investigational formulations of marketed products
    -Participants who are currently participating in any other interventional clinical
    study

    8. Participant had an adverse event (serious or non-serious) considered related to study treatment while participating in Study 200622 which resulted in permanent withdrawal of study treatment.
