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.2.3.1Full title, date and version of each sub-study and their related objectives
    Merck will conduct Future Biomedical Research on DNA (blood) specimens collected during this clinical trial. Such research is for biomarker testing to address emergent questions not described elsewhere in the protocol (as part of the main trial) and will only be conducted on specimens from appropriately consented subjects. The objective of collecting specimens for Future Biomedical Research is to explore and identify biomarkers that inform the scientific understanding of diseases and/or their therapeutic treatments. The overarching goal is to use such information to develop safer, more effective drugs, and/or to ensure that subjects receive the correct dose of the correct drug at the correct time.
    Merck llevará a cabo investigaciones biomédicas futuras con las muestras obtenidas específicamente con estos fines durante este ensayo clínico. Estas investigaciones tendrán por objeto el análisis de biomarcadores para abordar aspectos nuevos que no se describen en otras partes del protocolo (como parte del ensayo principal) y solo se llevarán a cabo en muestras de los sujetos que hayan otorgado el consentimiento correspondiente. El objetivo de la obtención de muestras para investigaciones biomédicas futuras consiste en estudiar e
    identificar biomarcadores que proporcionen información a los científicos
    sobre las enfermedades y sus tratamientos. El objetivo último es utilizar
    tal información para desarrollar fármacos más seguros y eficaces y/o para garantizar que los pacientes reciban la dosis correcta del fármaco adecuado en el momento preciso.

    E.4Principal exclusion criteria
    1. Has received prior systemic therapy for stage IV CRC. Subjects may have received prior adjuvant chemotherapy for CRC as long as it was completed at least 6 months prior to randomization.
    2. Is currently participating and receiving trial treatment in another study, or has participated in a study of an investigational agent and received trial treatment, or used an investigational device within 4 weeks of randomization.
    3. Has an active autoimmune disease that has required systemic treatment in past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs).
    Replacement therapy (eg. thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
    4. Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to randomization.
    5. Has had radiation therapy within 4 weeks prior to randomization of study therapy and who has not recovered to baseline from adverse events due to radiation therapy. Subjects who have been given palliative radiotherapy to peripheral sites (e.g., bone metastasis) may enter the study before 4 weeks have elapsed but must have recovered from any acute adverse effects.
    6. Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they have stable brain metastases [without evidence of progression by imaging as confirmed by magnetic resonance imaging (MRI) if MRI was used at prior imaging, or confirmed by computed tomography (CT) imaging if CT used at prior imaging] at least four weeks prior to the first dose of trial treatment; also, any neurologic symptoms must have returned to baseline], and have not used steroids for brain metastases for at least 28 days prior to trial initiation. This exception does not include carcinomatous meningitis, as subjects with carcinomatous meningitis are excluded regardless of clinical stability.
    7. Has had major surgical procedure, open biopsy or significant traumatic injury within 28 days prior to randomization.
    8. Has received prior therapy with an immune checkpoint inhibitor (e.g., anti-PD-1, anti- PD-L1, anti-PD-L2 agent, or anti-CTLA-4 agent, etc).
    9. Has another malignancy that is progressing or requires active treatment. Exceptions include non-melanomatous skin cancer that has undergone potentially curative therapy and in situ cervical carcinoma.
    10. Has received a live vaccine within 30 days of planned start of study therapy (see section 5.5.2).
    11. Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject?s participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating Investigator.
    12. Has a known history of Human Immunodeficiency Virus (HIV) (HIV 1/2 antibodies) , active chronic or acute Hepatitis B (e.g., HBsAg reactive) or Hepatitis C (e.g., HCV RNA [qualitative] is detected).
    13. Has known history of, or any evidence of interstitial lung disease or active, non - infectious pneumonitis.
    14. Has an active infection requiring systemic therapy.
    15. Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
    16. Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the screening visit through 180 days after the last dose of trial treatment for standard of care or 120 days after the last dose of
    pembrolizumab (MK-3475) arm.
    1.Haber recibido tratamiento sistémico previo para el CCR en estadio IV. Los sujetos podrán haber recibido previamente quimioterapia adyuvante para el CCR siempre que finalice al menos 6 meses antes de la aleatorización.
    2.Estar participando actualmente en otro estudio y recibir tratamiento del ensayo, haber participado en un estudio de un fármaco en investigación y haber recibido tratamiento del ensayo o haber usado un producto sanitario en investigación en las 4 semanas previas a la aleatorización.
    3.Padecer una enfermedad autoinmunitaria que haya necesitado tratamiento sistémico en los dos años precedentes (es decir, fármacos modificadores de la enfermedad, corticosteroides o inmunodepresores). El tratamiento de restitución (por ejemplo, tiroxina, insulina o corticosteroides en dosis fisiológicas para una insuficiencia suprarrenal o hipofisaria, etc.) no se considera una forma de tratamiento sistémico.
    4.Tener un diagnóstico de inmunodeficiencia o está recibiendo tratamiento con esteroides sistémicos u otra forma de tratamiento inmunosupresor en los 7 días previos a la aleatorización.
    5.Haberse sometido a radioterapia en las 4 semanas previas a la aleatorización del tratamiento del estudio y no haberse recuperado a los valores basales de acontecimientos adversos debidos a la radioterapia. Los sujetos que han recibido radioterapia paliativa para las localizaciones periféricas (p. ej., metástasis óseas) podrán incorporarse al estudio antes de que hayan transcurrido 4 semanas, pero deben haberse recuperado de cualquier posible efecto adverso agudo.
    6.Presentar metástasis activas en el sistema nervioso central (SNC) o meningitis carcinomatosa. Los sujetos con metástasis cerebrales tratadas previamente podrán participar siempre que se encuentren estables [sin indicios de progresión en los estudios de imagen confirmado mediante resonancia magnética (RM) si ese fue el método usado en el estudio de imagen anterior o confirmado mediante TAC si este fue el método empleado en el estudio de imagen anterior] durante al menos cuatro semanas antes de recibir la primera dosis del tratamiento del ensayo y regreso a la situación basal de los posibles síntomas neurológicos] y no hayan utilizado esteroides para las metástasis cerebrales desde como mínimo 28 días antes del inicio del ensayo.
    Esta excepción no se aplica a la meningitis carcinomatosa, puesto que los sujetos afectados por esta enfermedad estarán excluidos con independencia de la estabilidad clínica.
    7.Haberse sometido a un procedimiento quirúrgico mayor, biopsia abierta o lesión traumática significativa en los 28 días anteriores a la aleatorización.
    8.Haber recibido tratamiento anterior con un inhibidor del punto de control del sistema inmunitario (p. ej., agente anti-PD-1, anti-PD-L1 o anti-PD-L2 o agente anti-CTLA-4, etc.).
    9.Presentar otro tumor maligno que esté en progresión o necesite tratamiento activo. Son excepciones el cáncer de piel no melanomatoso que se ha sometido a tratamiento potencialmente curativo y el carcinoma de cuello uterino in situ.
    10.Haber recibido una vacuna de microorganismos vivos en los 30 días previos al comienzo previsto del tratamiento del ensayo (véase la sección 5.5.2).
    11.Tener antecedentes o datos actuales de cualquier trastorno, tratamiento o anomalía analítica que, en opinión del investigador, pueda confundir los resultados del ensayo, afectar a la participación del sujeto durante todo el ensayo o hacer que la participación no sea lo más conveniente para el sujeto.
    12.Tener antecedentes conocidos de infección por el virus de la inmunodeficiencia humana (VIH) (anticuerpos contra el VIH 1 o 2) o infección activa crónica o aguda por el virus de la hepatitis B (p. ej., HBsAg reactivo) o hepatitis C (p. ej., se detecta el ARN del VHC [a nivel cualitativo]).
    13.Presentar antecedentes conocidos o signos de neumopatía intersticial o de neumonitis no infecciosa activa.
    14.Presentar una infección activa con necesidad de tratamiento sistémico.
    15.Trastorno psiquiátrico o por abuso de sustancias que podría dificultar el cumplimiento de los requisitos del ensayo.
