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   43841   clinical trials with a EudraCT protocol, of which   7281   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
    Initial Treatment Period:

    To further evaluate the safety of natalizumab monotherapy by:
    1) evaluating the risk of hypersensitivity and immunogenicity following re-exposure to natalizumab and
    2) confirming the safety of switching from interferon beta (IFNb), glatiramer acetate (GA), or other MS therapies to natalizumab.

    Long-Term Treatment Period:

    To evaluate the long-term impact of natalizumab monotherapy on the progression of disability measured by EDSS changes over time.
    E.2.2Secondary objectives of the trial
    not available
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    Substudies are detailed in main protocol , version 7 Final dated 4
    March 2011. The substudies to be performed in any of the involved
    countries are as follows:
    - Axial fluid-attenuated inversion recovery (FLAIR) magnetic resonance
    imaging (MRI) imaging
    - Biological analysis for research into PML risk stratification
    - Genetic analysis
    The Axial fluid-attenuated inversion recovery (FLAIR) magnetic
    resonance imaging (MRI) imaging substudy was removed in Version 8 of the Protocol dated 14 February 2013
    E.3Principal inclusion criteria
    1) must give written informed consent and provide all authorizations required by local law(e.g. Protected Health Information [PHI])
    2) must be an MS subject who completed Study C-1801 or C-1802 and completed a Dosing Suspension Safety Evaluation (neurological examination or an MRI scan), or participated in Study IMA 04001 (STARS), or completed 48 weeks of treatment in Study 101-MS-322 in Canada. These subjects will be allowed to enter this study at the start of the Long Term Treatment period (Week 52)
    3) must be considered by the Investigator to be free of signs and symptoms suggestive of PML based on medical history, physical examination, or laboratory testing
    4) must be willing to discontinue and remain free from concomitant immunosuppressive or immunomodulatory treatment (including IFNb and GA) for the duration of the study.

    NOTE: Subjects who were found to be on placebo after being unblinded for a serious adverse event (SAE) in Study C-1801 or C-1802 are eligible to enroll in this study if they completed a Dosing Suspension Safety Evaluation, receive approval from the Biogen Idec Medical Director or the relevant Advisory Committee, meet all other inclusion criteria for this study, and are not excluded based on the exclusion criteria for this study.
    E.4Principal exclusion criteria
    Medical History
    1. considered by the Investigator to be immunocompromised, based on medical history, physical examination, or laboratory testing (results from the Dosing Suspension Safety Evaluation from Study C-1808 may be used), or due to prior immunosuppressive treatment
    2. history of persistent anti-natalizumab antibodies, based upon testing from prior natalizumab studies
    3. history of, or available abnormal laboratory results indicative of, any significant cardiac, endocrinologic, hematologic, hepatic, immunologic, metabolic, urologic, pulmonary, gastrointestinal, dermatologic, psychiatric (including major depression), renal, and/or other major disease that would preclude the administration of a recombinant humanized antibody immunomodulating agent for 48 weeks. The Investigator must re-review the subject’s medical fitness for participation and consider any diseases that would preclude treatment.
    4. history of malignancy (subjects with basal cell carcinoma that has been completely excised prior to study entry remain eligible)
    5. known history of human immunodeficiency virus infection or hematological malignancy
    6. history of organ transplantation (including anti-rejection therapy)
    7. history of severe allergic or anaphylactic reactions or known drug hypersensitivity
    8. a significant change (as determined by the Investigator) in the subject’s medical history from their previous natalizumab study
    9. a clinically significant infectious illness (e.g., cellulitis, abscess, pneumonia, septicemia) within 30 days prior to the Screening Visit in Study 101-MS-321

    Treatment History
    10. discontinued natalizumab in a previous study due to allergic reaction or any other SAE considered to be related to natalizumab treatment
    11. discontinued study drug in Study C-1801 or C-1802 because of an AE or due to reasons other than significant disease progression (as defined in the C-1801 and C-1802 protocols)
    12. treatment with immunosuppressant medications (e.g., mitoxantrone, cyclophosphamide, cyclosporine, azathioprine, methotrexate) within 3 months prior to screening

    Miscellaneous
    13. female subjects who are not postmenopausal for at least 1 year, surgically sterile (does not include tubal ligation), or willing to practice effective contraception (as defined by the Investigator) during the study
    14. women who are breastfeeding, pregnant, or planning to become pregnant while on study
    15. current enrollment in any other study treatment or disease study
    16. unwillingness or inability to comply with the requirements of this protocol, including the presence of any condition (physical, mental, or social) that is likely to affect the subject's ability to comply with the study protocol
    17. other unspecified reasons that, in the opinion of the Investigator and/or Biogen Idec, make the subject unsuitable for enrollment into this study.
    E.5 End points
    E.5.1Primary end point(s)
    Initial Treatment Period:

    To further evaluate the safety of natalizumab monotherapy by evaluating the risk of hypersensitivity and immunogenicity following re-exposure to natalizumab and, confirming the safety of switching from IFNb, GA or other MS therapies to natalizumab. The safety endpoint under consideration will be the incidence of AEs. The incidence of development of antibodies to natalizumab will also be assessed.

    Long-Term Treatment Period:

    To evaluate the long term impact of natalizumab monotherapy on the progression of disability measured by EDSS changes over time.
