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   43871   clinical trials with a EudraCT protocol, of which   7290   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.

    General information about the trial
    Main objective of the trial
    To evaluate the levels of FSH after treatment with 0.005% estriol vaginal gel in hormone receptor-positive postmenopausal women with early stage breast cancer in treatment with NSAIs in the adjuvant setting and symptoms of vaginal atrophy
    Protection of trial subjects
    Not applicable, it was not necessary to applied extra measures for protection of the subjects out of the good clinical practice environment
    Background therapy
    Patients were instructed not to take any additional medications (over-the-counter or other products) during the study without prior consultation with the investigator. Any medications including herbal supplements, vitamins, or treatment taken by the patient from 28 days prior to the start of study treatment and up to 30 days (±5 days) following the last dose of investigational product and the reason for their administration were recorded for analysis purposes. Routine postoperative care, such as dressing changes, suture removal, drain removal, or venous access (central or peripheral), did not need to be recorded. Anaesthetics used for any surgical procedures performed during the patient’s participation in the study was recorded as “unspecified anaesthesia”. The following treatments were prohibited throughout the duration of the active treatment phase: • Anticancer agents: No additional investigational or commercial anticancer agents such as chemotherapy, immunotherapy, targeted therapy, biological response modifiers or endocrine therapy (different than the NSAI: anastrozole or letrozole) were permitted during the active treatment phase. In general, any drugs containing “for the treatment of breast cancer” on the product insert were not permitted on study. • Hormone replacement therapy with estrogens or progestins, tibolone, topical estrogens (different from the study drug/placebo), phytoestrogen, megestrol acetate and selective estrogen-receptor modulators (eg, raloxifene, tibolone) were prohibited during the active treatment phase.

    Recruitment
    Recruitment details
    10 subjects were randomized for the initial safety phase in 2 sites in Spain;. 61 subjects were randomized for the study phase, 40 in Spain and 21 in Sweden

    Pre-assignment
    Screening details
    61 patients were randomized in the study phase, 50 of them received the 0.005% estriol vaginal gel and 11 received placebo. A total of 52 patients completed the study treatment, 43 with the estriol vaginal gel and 9 with the placebo. 25 screened patients coulnot be randomized, 14 due to consent withdrawal and 11 due to not meet the inc/exc criteria

    Blinding implementation details
    Patients were randomized to receive 0.005% estriol vaginal gel or placebo vaginal gel, in a 4:1 proportion. The study drug, and its vehicle in gel (placebo vaginal gel) were of identical appearance and had the same aroma and the same texture in order to maintain the double blind.
