Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   35177   clinical trials with a EudraCT protocol, of which   5751   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).
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    A.3Full title of the trial
    An open-label, non-comparative, multi-centre study to assess the efficacy and safety of bicalutamide when used in combination with anastrozole for the treatment of gonadotropin-independent precocious puberty in boys with testotoxicosis.
    A.3.1Title of the trial for lay people, in easily understood, i.e. non-technical, language
    The objective of this study is to investigate whether bicalutamide given in combination with anastrozole once daily for 12 months is effective in treating testotoxicosis in boys. Testotoxicosis is a condition that causes early puberty including growth in height, and development of muscles and sexual organs.

    E.2.1Main objective of the trial
    Efficacy defined by reduction in growth rate after 12 months treatment
    E.2.2Secondary objectives of the trial
    Efficacy defined by reduction in bone maturation rate, normalization of growth rate, increase in predicted adult height, safety and tolerability, PK and PD.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    Provision of written infromed consent of parent/legal guardian and subject assent (as needed by local requirements)
    Male aged 2 years and over
    Diagnosis of testotoxicosis based on:
    - Cinical features of progressive sexual precocity documented by Tanner staging and evidence of symmetrical testiclular enlargement;
    - Clinical features of significantly advanced bone age (defined as bone age of at least 12 months beyond chronological age);
    - pubertal levels of serum testosterone;
    - prepubertal levels of serum gonadotrophins;
    - lack of an increase in serum gonadotrophin levels following GnRH stimulation.

    Other pathology excluded by:
    - undetectable plasma b human chorionic gonadotroin (bHCG). Samples with values below the LOQ will be reported as "<10 IU/L" which in the clinical setting equate to 'undetectable';
    - normal levels of 17-hydroxyprogesterone (17-OHP);
    - normal levels of dehydroepiandrosterone sulphate (DHEAS)

    Naive to anti androgen receptor therapy:
    (Note: ketoconazole and Spironolactone are considered acceptable as is prior use of anastrozole or other aromatose inhibitors)

    A documented reliable height measurement taken > 6 months prior to study enrollment. Additionally for subjects who have previously received ketoconazole or spironolactone treatment, a documented reliable height measurement taken immediately prior to beginning this treatment.

    (Note: for subjects who received such previous treatment only a single assessment is needed if it was taken immediately prior to beginning treatment and > 6 months prior to study entry)

    Subjects should be free of endocrine or other effects of previous treatment for testotoxicosis prior to study entry: to ensure this there should be 15 days or 4 drug half lives (whichever is longer) washout period from prior medication for testotoxicosis.


    E.4Principal exclusion criteria
    Evidence of central precocious puberty as demonstrated by GnRH stimulation test.
    Serum concentration of total or direct bilirubin, GGT, AST or ALT greater than 1.5 times the upper limit of normal for age.
    Serum concentration of creatinine greater than 1.5 times the upper limit of normal for age.
    Any concomitant medical condition that, in the opinion of the investigator, may expose a subject to an unacceptable level of safety risk or that affects subject compliance.
    Known hypersensitivity to any of the study medications.
    Participation in a clinical study at the time of enrollment.
