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   44338   clinical trials with a EudraCT protocol, of which   7368   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.3Principal inclusion criteria
    A subject will be eligible for inclusion in this study only if ALL of the following criteria apply:

    1. Informed Consent: Prior to commencing any study related activities, subjects must be able and willing to provide written informed consent, and an assent for subjects under 18 years of age, at Visit 0 (or Visit 1 if these Visits are conducted on the same day).
    2. Continuous Mepolizumab Treatment during MEA115666 or 201312:
    Participation through the Follow Up/Exit Visit or Early Withdrawal Visit and documented evidence of treatment with mepolizumab with no treatment gaps of more than 12 weeks (84 days) between any two doses within MEA115666 or 201312. (A treatment gap of more than 12 weeks [84 days] cannot occur between the end of MEA115666 or 201312 and Visit 1).

    3. Current Anti-Asthma Therapy: Asthma is currently being treated with a controller medication and the subject has been on a controller medication for the past 12 weeks. Subjects will be expected to continue controller therapy for the duration of the study.

    4. Male or Eligible Female Subjects:
    A female is eligible to enter and participate in the study if she is of:
    Non-child bearing potential (i.e., physiologically incapable of becoming pregnant, including any female who is post-menopausal or surgically sterile).
    Surgically sterile females are defined as those with a documented hysterectomy and/or bilateral oophorectomy or tubal ligation. Post-menopausal females are defined as being amenorrhoeic for greater than 1 year with an appropriate clinical profile, e.g., age appropriate, > 45 years, in the absence of hormone replacement
    therapy.
    OR
    Child bearing potential, has a negative pregnancy test at screening, and agrees to acceptable contraceptive methods approved in their local country, when used consistently and correctly (i.e., in accordance with the approved product label and
    the instructions of the physician) for the duration of the study and for 4 months after the last study drug administration (see Appendix 5).
    A urine pregnancy test is required of all females of child-bearing potential at each scheduled study visit prior to the injection of study treatment, and at the Exit Visit, EW or Discontinuation of IP Visit.
    5. French subjects: In France, a subject will be eligible for inclusion in this study only if either affiliated to or a beneficiary of a social security category.
    E.4Principal exclusion criteria
    A subject will not be eligible for inclusion in this study if ANY of the following criteria apply:

    1. MEA115666 or 201312 IP Discontinuation: Subjects withdrawn from IP or withdrawn from study participation from either MEA115666 or 201312 for safety reasons

    2. Health Status: Clinically significant deterioration in health status at the completion of participation or EW from either the MEA115666 or 201312 trials which in the opinion of the investigator would make the subject unsuitable for participation in this study.

    3. Pregnancy: Subjects who are pregnant or breastfeeding. Subjects should not be enrolled if they plan to become pregnant during the time of study participation.

    4. Cardiovascular: Subjects who have severe or clinically significant cardiovascular disease uncontrolled with standard treatment. Including but not limited to:
    - known ejection fraction of <30% OR
    - severe heart failure meeting New York Heart Association Class IV
    classification OR
    - hospitalised in the 12 months prior to Visit 1 for severe heart failure meeting New York Heart Association Class III OR
    - angina diagnosed less than 3 months prior to Visit 1 or at Visit 1

    5. 12-Lead ECG: ECG which has a clinically significant abnormality observed at the Screening Visit as determined by the investigator. Subjects with the following abnormalities are excluded from study participation:
    - QTcF > 450 msec, or
    - QTcF >480 msec for subjects with Bundle Branch Block.

    6. Malignancy: A current malignancy or previous history of cancer in remission for less than 12 months prior to screening (Subjects that had localized carcinoma of the skin which was resected for cure will not be excluded). [Note for South Korea:
    Korean subjects with a diagnosis of malignancy within 5 years are excluded].

    7. Other Monoclonal Antibodies: Subjects who have received any monoclonal antibody within 5 half-lives of Visit 1.

    8. Adherence: Subjects who have known evidence of lack of adherence within studies MEA115666 or 201312 (less than 80%) to controller medications, scheduled study visits and/or ability to follow physician’s recommendations.

    9. Smoking status: Current smokers

    10. Inability to read: In the opinion of the Investigator, any subject who is unable to read and/or would not be able to complete a questionnaire.
