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   43865   clinical trials with a EudraCT protocol, of which   7286   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.3Principal inclusion criteria
    1. The patient must have consented to participate. 2. The diagnosis of invasive adenocarcinoma of the breast must have been made by core needle biopsy. 3. Local testing on the diagnostic core must have determined the tumor to be ER-negative, PgR-negative, and HER2-negative by current ASCO/CAP guidelines. 4.Central testing for ER, PgR, and HER2 will be performed, and the tumor must be determined to be ER-negative, PgR-negative, and HER2-negative by current ASCO/CAP Guidelines Recommendations. Formalin-fixed, paraffin-embedded (FFPE) breast tissue from core biopsy has therefore to be sent to the GBG central pathology laboratory prior to randomization for central confirmation of TNBC status and for correlative science studies. 5. The tumor specimen used for central ER, PgR, and HER2 testing must also be used for central testing of PD-L1 status using the Ventana PD-L1 (SP142) assay kit. Patients will be eligible irrespective of PD-L1 testing result including PD-L1 indeterminate. Patients will be classified as positive, negative, or indeterminate for stratification purposes. 6. Patients must be > or = 18 years old. 7. Patient may be female or male. 8. The ECOG performance status must be 0-1. 9. The primary tumor can be clinical stage T2 or T3, if clinically node negative according to AJCC 7th Edition. If the regional lymph nodes are cN1 and cytologically or histologically positive or cN2–N3 with or without a biopsy, the primary breast tumor can be clinically T1c, T2, or T3. 10. Ipsilateral axillary lymph nodes must be evaluated by imaging (ultrasound, and/or MRI) within 42 days prior to study entry. If suspicious or abnormal, FNA or core biopsy is recommended. 11. Patients with synchronous bilateral or multicentric HER2-negative breast cancer are eligible as long as the highest risk tumor is ER-negative and PgR-negative and meets stage eligibility criteria. All of the other invasive tumors must also be HER2-negative by ASCO/CAP Guidelines based on local testing. Central testing to confirm TNBC status is only required for the highest risk tumor. 12. Blood counts performed within 28 days prior to randomization. 13. Evidence of adequate hepatic function performed within 28 days prior to randomization.
    14. Patients with AST or ALT or alkaline phosphatase > ULN are eligible for inclusion in the study if liver imaging (CT, MRI, abdominal ultrasound, PET-CT, or PET scan) performed within 28 days prior to randomization does not demonstrate metastatic disease and the requirements in criterion 13 are met. 15. Patients with alkaline phosphatase that is > ULN but < or = 2.5 x ULN or with unexplained bone pain are eligible for inclusion in the study if bone imaging (bone scan, PET-CT scan, or PET scan) supported by additional studies when indicated (CT, x-ray, MRI) performed within 28 days prior to randomization does not demonstrate metastatic disease. 16.Patients with N2 or N3 nodal disease or T3 primary disease must undergo liver and bone imaging (as described in criteria 14 and 15) within 28 days prior to randomization. 17. Creatinine clearance > or = 50 mL/min performed within 28 days prior to randomization. 18. PT/INR < or = ULN within 28 days prior to randomization. For laboratories that do not report an ULN for the INR assay, use < or = 1.2 as the value for the ULN. Patients receiving therapeutic anti-coagulants are not eligible. 19.A serum TSH and AM (morning) cortisol performed within 28 days prior to randomization to obtain a baseline value. 20. LVEF assessment must be performed within 42 days prior to randomization. The LVEF must be > or = 55% regardless of the cardiac imaging facility's lower limit of normal. 21. For women of childbearing potential and male patients with female partners of childbearing potential: agreement to remain abstinent or use contraceptive methods that result in a failure rate of < 1% per year during the treatment period and for at least 5 months after the last dose of atezolizumab/placebo or 12 months after the last dose of chemotherapy. A woman is considered to be of childbearing potential if she is not postmenopausal, has not reached a postmenopausal state (> or = 12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus). 22. Patient must be willing and able to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures.
    1. Los pacientes tienen que haber dado su consentimiento para participar. 2. El diagnóstico de adenocarcinoma invasivo de mama deberá haberse realizado mediante biopsia con aguja gruesa. 3. Las pruebas locales en el diagnóstico mediante biopsia con aguja gruesa deberán haber determinado si el tumor es ER negativo, PgR negativo y HER2 negativo según las guías actuales de la ASCO/CAP. 4. Se realizarán pruebas centrales para ER, PgR, y HER2, y se determinará si el tumor es ER negativo, PgR negativo y HER2 negativo según las recomendaciones y guías de la ASCO/CAP. 5. La muestra tumoral utilizada para las pruebas centrales de ER, PgR y HER2 se utilizará también para las pruebas centrales del estado de PD-L1 utilizando el kit de ensayo Ventana PD-L1 (SP142). Los pacientes serán elegibles independientemente de los resultados de la prueba de PD-L1, incluyendo la no determinación de PD-L1. Los placientes serán clasificados como positivos, negativos o indeterminados a efectos de estratificación. 6. Los pacientes deberán tener > o = 18 años. 7. Los pacientes pueden ser hombres o mujeres. 8. El estado funcional ECOG debe ser 0-1. 9. El tumor primario puede ser de estadio clínico T2 o T3 si el ganglio es clínicamente negativo según el sistema de estadificación del AJCC, 7ª edición. Si los ganglios linfáticos regionales son cN1 y citológica o histológicamente positivos o cN2–N3 con o sin biopsia, el tumor de mama primario puede ser clínicamente T1c, T2 o T3. 10.

    protocolo o imposibilidad de operar, recurrencia invasiva local después de la mastectomía, recurrencia invasiva local en la mama ipsilateral después
    de la lumpectomía, recurrencia regional, recurrencia a distancia, cáncer de mama invasivo contralateral, segundo cáncer primario que no sea de mama
