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   43851   clinical trials with a EudraCT protocol, of which   7283   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.

    D.8 Information on Placebo
    E. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Bone loss attributed to cessation of ovarian estrogen production is common in postmenopausal women. In postmenopausal women with breast cancer, treatment with an aromatase inhibitor may further reduce or eliminate estrogen activity, leading to potential acceleration of bone loss. This study will evaluate the effects of letrozole and tamoxifen on bone and lipid metabolism in postmenopausal women with rersected, receptor positive early breast cancer
    MedDRA Classification
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To assess the effect of letrozole versus tamoxifen on the bone mineral density (BMD) of the lumbar spine (L2 to L4) as measured by dual energy X-ray absorptiometry (DXA) at 2 years in postmenopausal women with resceted hormone receptor-positive primary breast cancer. The primary enpoint is therefore percent change from baseline in lumbar spine (L2-L4) BMD at 2 years.
    E.2.2Secondary objectives of the trial
    To evaluate teh effect of long-term use of letrozole on bone mineral density, marker of bone metabolism, and fasting serum lipid profile in teh adjuvant treatment of postmenopausal women with resected hormone receptor-positive breast cancer. Those parameters will be evaluated as a function of treatment time. In addition, general safety and efficacy will be evaluated as well as a secondary objective.
    E.2.3Trial contains a sub-study Information not present in EudraCT
    E.3Principal inclusion criteria
    1. Female sex.
    2. Postmenopausal hormone status defined as:
    •Patients with menostasis > 12 months or history of oophorectomy
    •Patients ≥ 55 years with history of hysterectomy or having continued/renewed menstruation on cyclic hormone treatment
    •Patients of 50-54 years: Menopausal status is determined on the basis of FSH/LH values
    3. Histologically confirmed resected breast cancer AND eligible for adjuvant endocrine therapy. As a minimum, patients must have receptor positive tumours, which is defined either as ER and/or PgR ≥10 fmol/mg cytosol protein; or ≥ 10% of the tumour cells positive by immunocytochemical evaluation.
    4. Adequate bone marrow function (WBC > 3.0 x 10 9 /L, platelets ≥ 100.0 x 10 9 /L, and haemoglobin > 10 g/dL).
    5. Documented evidence of adequate renal function (creatinine < 180 µmol/L) and hepatic function (bilirubin < 30 µmol/L, ALT (SGPT) < 1.5 x upper normal limit of the laboratory).
    6. Life expectancy at least 24 months.
    7. Written voluntary informed consent prior to initiation of any study procedure.
    8. Willingness to undergo all scheduled tests and examinations for evaluation of bone density and bone metabolism, and lipid profiles in addition to the standard assessments for monitoring their breast cancer status.
    E.4Principal exclusion criteria
    If any of the following criteria is met, the patient is not eligible for the study.
    1. Patients with distant metastases as defined by the criteria of the Danish Breast cancer group.
    2. Pre-existing bone disease (e.g. osteomalacia, osteogenesis imperfecta, Paget’s disease).
    3. Patients receiving bisphosphonates for more than 3 months before randomization.
    4. Chronic treatment with drugs known to interfere with bone metabolism, e.g.
    •Anticonvulsants within the past year.
    •Corticosteroids at doses greater than the equivalent of 5 mg/day prednisone for more than two weeks in the past 6 months.
    •Any previous treatment with sodium fluoride at daily doses ≥ 5 mg/day for a period exceeding 1 month.
    •Anabolic steroids in the past 12 months.
    •Long term use of coumarins derivatives and heparin at the time of randomization.
    5. Metabolic diseases known to interfere with bone metabolism (e.g. Hyper-, Hypoparathyroidism, uncontrolled thyroid disease, Cushing Disease, Vitamin D deficiency, Malabsorption Syndrome, etc.).
    6. Treatment with lipid lowering agents within the 3 months prior to randomization (this exclusion criteria does not apply to patients randomized in the UK).
    7. Patient receiving other anti-cancer treatment.
    8. Previous neoadjuvant / adjuvant chemotherapy and/or previous adjuvant endocrine therapy (eg anti-estrogens, aromatase inhibitors).
    9. History of previous or concomitant malignancy within the past 5 years other than adequately treated basal or squamous cell carcinoma of the skin or in situ carcinoma of the cervix. Patients who have had a previous other malignancy must have been disease free for five years. Patients with endometrial cancer and/or invasive breast cancer at any time in their medical history are excluded. Patients with invasive bilateral breast cancer are excluded. Patients with vaginal discharge/vaginal bleeding with evidence of malignancy are excluded.
    10. Any other non-malignant systemic diseases (cardiovascular, renal, hepatic, lung embolism, etc.) which would prevent prolonged follow-up.
    11. History of cardiovascular diseases (including earlier known acute myocardial infarction or angina pectoris), cerebrovascular events, venous thromboembolic events (including deep-vein thromboses).
    12. History of non-compliance to medical regimens and patients who are considered potentially unreliable.
    13. History of systemic investigational drugs use within the past 30 days.
    14. Presence of any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial.
    15. Current use of hormone replacement therapy (HRT must be stopped at least 4 weeks before study treatment is initiated).

    Additional exclusion criteria for spine DXA:
    1. History of complaints, or surgery of the lumbosacral spine, with or without implantable devices.
    2. Any disease of the spine that would preclude the proper acquisition or assessment of a lumbar spine DXA (e.g. degenerative joint disease) to ensure that the interpretation of DXA scan is not affected by anatomical artifacts.
