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   44334   clinical trials with a EudraCT protocol, of which   7366   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
    Subjects are eligible to be included in the study only if all of the following criteria apply:
    -Subject has provided informed consent/assent prior to initiation of any Study 20170534 specific activities/procedures.
    Subject’s legally acceptable representative has provided informed consent when the subject is legally too young to provide informed consent and the subject has provided written assent based on local regulations and/or guidelines prior to any study-specific activities/procedures being initiated.
    - Subject was enrolled in Study 20130173 and:
     - completed the 20130173 EOS visit (regardless of completing or
    ending investigational product early).
    OR
    - Subjects who do not reconsent to transition to 3-Month Dosing
    Regimen on Study 20130173 are also eligible for enrollment
    OR

    IP stopping criteria and was required to early terminate from the
    study.
    E.4Principal exclusion criteria
    Subjects are excluded from the study if any of the following criteria apply:
    Prior/Concomitant Therapy
    -Treatment with any prohibited proscribed medications during Study 20130173 while receiving denosumab. Eligibility into study treatment with alternative osteoporosis medication/s of investigator's choice, follow guidelines per the specific alternative osteoporosis medication/s selected. For subjects off-treatment (observation only), no prohibited medications apply.
    Prior/Concurrent Clinical Study Experience
    -Subjects currently receiving treatment in another investigational device or drug study other than Study 20130173. Other investigational procedures while participating in this study are excluded.
    Other Exclusions
    -For subjects expected to receive investigational product (denosumab)
    at study day 1:
    -Female subject is pregnant or breastfeeding or planning to become pregnant or breastfeed during treatment and for an additional 5 months after the last dose of denosumab. Females of childbearing potential (Tanner Stage ≥ 2) should only be included in the study after a negative highly sensitive urine or serum pregnancy test. For study
    treatment with alternative osteoporosis medication/s of investigator's
    choice, follow guidelines per the specific alternative osteoporosis
    medication/s selected. For subjects off-treatment (observation only), no exclusion applies.
