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   44334   clinical trials with a EudraCT protocol, of which   7366   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. Male/female participants who are at least 18 years of age on the day of signing informed consent with histologically or cytologically-confirmed R/M HNSCC that is considered incurable by local therapies will be enrolled in this study.
    2. A male participant must agree to use contraception as detailed in Appendix 5 of this protocol during the treatment period and for at least 120 days after the last dose of pembrolizumab and epacadostat, or pembrolizumab alone, and for at least 180 days after the last dose of the EXTREME regimen, whichever is longer. He must also refrain from donating sperm during this period. Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the participant.
    3. A female participant is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies:
    a.) Not a woman of childbearing potential (WOCBP) as defined in Appendix 5 OR
    b.) A WOCBP who agrees to follow the contraceptive guidance in Appendix 5 during the treatment period and for at least 120 days after the last dose of pembrolizumab and epacadostat, or pembrolizumab alone, and for at least 180 days after last dose of the EXTREME regimen, whichever is longer. Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the participant.
    4. The participant (or legally acceptable representative if applicable) provides written informed consent for the study.
    5. Have measurable disease by CT or MRI based on RECIST 1.1 as determined by site radiology. Lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions following radiation therapy.
    6. Have an ECOG PS of 0 or 1 within 7 days prior to randomization.
    7. Have adequate organ function as defined in the protocol. Specimens must be collected within ≤10 days prior to the start of study treatment.
    8. Have documentation of results from testing of HPV status for oropharyngeal cancer defined as p16 IHC testing using CINtec® p16 Histology assay and a 70% cutoff point. If HPV status was previously tested using this method, no additional testing is required.
    9. Have a baseline archival tumor specimen available or is willing to undergo a pre-study treatment tumor core or excisional biopsy of a tumor lesion not previously irradiated, to obtain the specimen. Fine needle aspirate (FNA) and bone metastases samples are not acceptable.
    1.En este estudio se incluirá a participantes de ambos sexos, con una edad mínima de 18 años el día de la firma del consentimiento informado, con CECC R/M confirmado mediante histología o citología que se considere incurable mediante tratamientos locales.
    2.Los varones deberán comprometerse a utilizar métodos anticonceptivos tal como se detalla en el apéndice 5 de este protocolo durante el período de tratamiento y hasta, como mínimo, 120 días después de la última dosis de pembrolizumab y epacadostat, o pembrolizumab en monoterapia, así como hasta 180 días después de la última dosis de la pauta EXTREME, lo que suponga más tiempo. También deberán abstenerse de donar semen durante este período. Nota: La abstinencia será aceptable cuando sea el modo de vida habitual y el método anticonceptivo preferido del participante.
    3.Podrá participar toda mujer que no esté embarazada ni dando el pecho y que cumpla al menos una de las condiciones siguientes: a.) No es una mujer en edad fértil (MEF) según se define en el Apéndice 5 O b.) Es una MEF que se compromete a seguir las recomendaciones sobre métodos anticonceptivos recogidas en el apéndice 5 durante el período de tratamiento y hasta, como mínimo, 120 días después de la última dosis de pembrolizumab y epacadostat, o pembrolizumab en monoterapia, así como hasta 180 días después de la última dosis de la pauta EXTREME, lo que suponga más tiempo. Nota: La abstinencia será aceptable cuando sea el modo de vida habitual y el método anticonceptivo preferido de la participante.
    4.El participante (o su representante legal cuando proceda) otorga su consentimiento informado por escrito para el estudio.
    5.Presencia de enfermedad mensurable mediante TC o RM, conforme a los criterios RECIST 1.1, según determine el departamento de radiología del centro. Las lesiones ubicadas en una zona previamente irradiada se considerarán mensurables siempre que se haya constatado progresión en dichas lesiones tras la radioterapia.
    6. Presencia de un estado funcional del ECOG de 0 o 1 en los 7 días previos a la aleatorización.
    7.Presencia de una función orgánica adecuada, que se define en el Protocolo . Las muestras se obtendrán en los 10 días previos al comienzo del tratamiento del estudio.
    8.Documentación de los resultados de un análisis del estado del VPH en el cáncer de bucofaringe, definido como un análisis mediante IHQ de p16 utilizando el método de análisis histológico de p16 CINtec® y un valor umbral del 70 %.

    9.Disponibilidad de una muestra tumoral de archivo basal o disposición a someterse a una biopsia con aguja gruesa o por escisión, antes del tratamiento del estudio, de una lesión tumoral no irradiada previamente para obtener la muestra. Las muestras de aspirado con aguja fina (AAF) y metástasis óseas no son aceptables.
