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.

    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Written informed consent prior to beginning specific protocol
    procedures, including expected cooperation of the patients for the
    treatment and follow-up, must be obtained and documented according to the local regulatory requirements.
    2. Willingness and ability to provide archived formalin fixed paraffin
    embedded tissue block or a partial block from surgery after neoadjuvant chemotherapy and from core-biopsy before start of neoadjuvant chemotherapy, which will be used for centralized retrospective confirmation of hormone- and HER2-status and to evaluate correlation between genes, proteins, and mRNAs relevant to the endocrine and cell cycle pathways and sensitivity/resistance to the investigational agents.
    3. Histologically confirmed unilateral or bilateral primary invasive
    carcinoma of the breast.
    4. Residual invasive disease post-neoadjuvant either in the breast or as residual nodal invasion.
    5. Centrally confirmed hormone-receptor-positive (>=1% positive
    stained cells) and HER2-normal (IHC score 0-1 or FISH negative (in-situ hybridization (ISH) ratio <2.0 status assessed preferably on tissue from post-neoadjuvant residual invasive disease of the breast, or if not possible, of residual nodal invasion. In case of bilateral breast cancer status has to be confirmed for both sides.
    6. Centrally assessed Ki-67, pRB, and Cyclin D1 status assessed
    preferably on post-neoadjuvant residual invasive disease of the breast, or if not possible, of residual nodal invasion.
    7. Patients must have received neoadjuvant chemotherapy of at least 6 cycles at a minimum duration of 16 weeks. This period must include 6 weeks of a taxane-containing therapy (Exception: Patients with progressive disease that occurred after at least 6 weeks of taxane-containing neoadjuvant treatment, a total treatment period of less than 16 weeks is also eligible).
    8. Adequate surgical treatment including resection of all clinically
    evident disease and ipsilateral axillary lymphnode dissection.
    Histologically complete resection (R0) of the invasive and ductal in situ tumor is required in case of breast conserving surgery as the final treatment. No evidence of gross residual disease (R2) is required after total mastectomy (R1 resection is acceptable). Axillary dissection is not required in patients with a negative sentinel-node biopsy before (pN0, pN+(mic)) or after (ypN0, ypN+(mic) neoadjuvant chemotherapy.
    9. Less than 16 weeks interval since the date of final surgery and date of randomization (including the radiotherapy period).
    10. Completion of adjuvant radiotherapy. Radiotherapy is indicated to the breast in all patients treated with breast conserving surgery and to chest wall in all patients with cT3/cT4, R1 or ypN+ disease treated by mastectomy.
    11. No clinical evidence for locoregional or distant relapse during or after preoperative chemotherapy. Local progression during chemotherapy is not an exclusion criterion.
    12. A clinical-pathologic stage ? estrogen/grade (CPS-EG) score of >=3 calculated using local estrogen receptor status and grade assessed on core biopsies taken before start of neoadjuvant treatment.
    13. Age at diagnosis at least 18 years.
    14. Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 or 1
    15. Resolution of all acute toxic effects of prior anti-cancer therapy or surgical procedures to NCI CTCAE version 4.0 Grade ?1 (except alopecia or other toxicities not considered a safety risk for the patient at investigator's discretion).
    16. Estimated life expectancy of at least 5 years irrespective of the
    diagnosis of breast cancer.
    17. The patient must be accessible for scheduled visits, treatment and follow-up. Patients registered on this trial must be treated at the participating center which could be the Principal or a Co- investigator's site.

    E.5 End points
    E.5.1Primary end point(s)
    The primary endpoint is iDFS. iDFS will be defined according to Hudis et al as the time period between randomization and first event (ipsi- or contralateral invasive in-breast or loco-regional recurrence, distant recurrence, death from breast cancer, death from non-breast cancer cause, death from unknown cause, invasive contralateral breast cancer, second primary invasive cancer [non-breast]).
    La variable principal de eficacia es la supervivencia libre de enfermedad infiltrante (SLEi) que se define según Hudis (J Clin Oncol 2007) como el periodo de tiempo entre la aleatorización y el primer evento (recurrencia en mama o locorregional infiltrante ipsilateral o contralateral, recurrencia a distancia, muerte por cáncer de mama, muerte no causada por el cáncer de mama, muerte por causa desconocida, cáncer de mama infiltrante contralateral, segundo cáncer primario infiltrante (que no sea de mama)).
    E.5.1.1Timepoint(s) of evaluation of this end point
    Final analysis on the primary endpoint will be conducted when 233
    events in iDFS have been observed. Approx. IV 2018
    Two interim efficacy analyses will be performed in the study.
    The first interim analysis will take place after the first 78 events (1/3 of the total events) have occurred and the second interim analysis will take place after the first 155 events (2/3 of the total events) have occurred. It was estimated that the 1st interim analysis will occur <3 years and the 2nd interim analysis will occur 4.3 years from first patient randomized.
    El análisis final de la variable principal y las variables secundarias de eficacia (excepto para SG) se realizará cuando se hayan observado 233 eventos de SLEi.
    Aproximadamente IV 2018.
    En el estudio se realizarán dos análisis intermedios de eficacia.
    El primer análisis intermedio tendrá lugar después de que hayan ocurrido los primeros 78 eventos (1/3 del total de eventos) y el segundo análisis intermedio tendrá lugar después que hayan ocurrido los primeros 155 eventos (2/3 del total de eventos).
    Se estima que el primer análisis intermedio se realizará <3 años y el segundo análisis intermedio se realizará 4,3 años desde la aleatorización de la primera paciente.

    ?Low and high risk groups (defined by EndoPredict? risk of relapse (ROR) or other any other available test at the time of analysis)
    ?Low and high risk groups defined by a standardized image analysis system for Ki67
    ?Circulating tumor cells (CTCs)
