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   44020   clinical trials with a EudraCT protocol, of which   7318   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.1.3Condition being studied is a rare disease Yes
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective of this study is to assess the efficacy of bicalutamide when used in combination with anastrozole in terms of a reduction in growth rate after 12 months treatment of precocious puberty in boys with testotoxicosis by assessment of change in growth rate after 12 months of treatment relative to the growth rate during the 6 months or more pre-study period.
    E.2.2Secondary objectives of the trial
    1. To investigate efficacy of bicalutamide when used in combination with
    anastrozole in terms of reduction in growth rate after 6 months treatment by
    assessment of change in growth rate after 6 months of treatment relative to the
    growth rate during the 6 months or more pre-study period.
    2. To investigate efficacy of bicalutamide when used in combination with
    anastrozole in terms of reduction in bone age maturation rate after 6 & 12
    months treatment by assessment of change in rate of bone age maturation after 6
    & 12 months of treatment relative to rate of bone age maturation during the 6 months or more pre-study period for patients with retrospective bone age.
    3. To investigate efficacy of bicalutamide when used in combination with
    anastrozole in terms of normalization of growth rate by number and percentage of
    subjects who achieve and/or maintain growth rates between the 5 th and the 95 th
    percentile for chronological age at 3, 6, 9 and 12 months of treatment.

    E.2.3Trial contains a sub-study Information not present in EudraCT
    E.3Principal inclusion criteria
    1. Provision of written informed consent of parent/ legal guardian and subject assent
    (as needed by local requirements)
    2. Male aged 2 years and over
    3. Diagnosis of testotoxicosis based on the following:
    -clinical features of:
    i) progressive sexual precocity documented by Tanner staging and evidence of
    symmetrical testicular enlargement
    ii) 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 gonadotropins
    - lack of an increase in serum gonadotropin levels following GnRH stimulation
    - other pathology excluded by:
    i) undetectable plasma b human chorionic gonadotropin (bHCG)*
    *Samples with values below the LOQ will be reported as "<10 IU/L" which in the clinical setting equate to 'undetectable'.
    ii) normal levels of 17-hydroxyprogesterone (17-OHP)
    iii) normal levels of dehydroepiandrosterone sulphate (DHEAS)
    4. Naïve to anti androgen receptor therapy (Note: Ketoconazole and spironolactone are considered acceptable as is prior use of anastrozole or other aromatase inhibitors)
    5. A documented reliable height measurement taken at least 6 months prior to study
    enrolment. 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 at leats 6 months prior to study entry)
    6. 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 the longer) washout period from prior medication for
    testotoxicosis
    E.4Principal exclusion criteria
    1. Evidence of central precocious puberty as demonstrated by GnRH stimulation test
    2. Serum concentration of total or direct bilirubin, GGT, AST or ALT greater than 1.5
    times the upper limit of normal for age
    3. Serum concentration of creatinine greater than 1.5 times the upper limit of normal
    for age
    4. 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
    5. Known hypersensitivity to any of the study medications
    6. Participation in a clinical study at the time of enrolment
