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.

    Tasa de respuesta objetiva (RO) definida de acuerdo con los Criterios de Evaluación de Respuesta en Tumores Sólidos (RECIST) v.1.1 e iRECIST, en su caso, en pacientes con CCR con MSS, CE con MSS, CCR con MSI y CE con MSI.
    E.5.1.1Timepoint(s) of evaluation of this end point
    Baseline to the end of the study (Patients will have scans done q8w for the first 48 weeks, and then q12w thereafter (relative to the date of randomization) until confirmed objective disease progression)
    Basal hasta el final del estudio (se realizarán exploraciones radiológicas a los pacientes cada 8 semanas durante las primeras 48 semanas, y luego cada 12 semanas a partir de entonces (en relación con la fecha de aleatorización) hasta que se confirme la progresión objetiva de la enfermedad)
    E.5.2Secondary end point(s)
    The secondary endpoints for assessment of the antitumor activity will include:
    • To assess the antitumor activity of durvalumab and durvalumab + tremelimumab in MSS CRC/EC and MSI CRC/EC based on additional measures:
    o Duration of response (DoR), defined as time from initial tumor response to disease progression
    o Progression free survival (PFS), defined as time from treatment initiation to progressive disease or death
    o Overall survival (OS), defined as time from treatment initiation to death
    o Time to maximum response (TTMR), defined as time from treatment initiation to maximum response documented by CT-Scans
    o Immune-related (ir) response rate (irRR) as measured by iRECIST with the use of unidimensional measurement
    • To assess the safety of durvalumab and durvalumab + tremelimumab in the cohort of patients included in the trial.
    • Characterize at a single cell resolution the transcriptome of the tumors at baseline and upon treatment with immunotherapy, including at the time of maximal response, and at progression.
    • To correlate the antitumor activity of durvalumab and durvalumab + tremelimumab with other biomarkers on tumor tissue and in blood samples.
    The endpoints for biomarkers assessment on tumor tissue and peripherical blood will include: Genomic and immune biomarkers:
    • Correlate the clinical response to immunotherapy with the whole transcriptome measured at single cell level and by RNA-seq at baseline, upon treatment, at maximum response, at progression and in cases of immunotoxicity.
    • Correlate the clinical response to immunotherapy with the DNA-seq – ctDNA-seq, targeted next-generation DNA-seq, ATAC-seq and exome DNA-seq.
    • Prediction of patient-specific tumor neo-antigens from the analysis of the mutanome (RNA-seq and exome DNA-seq) and correlate with clinical response to immunotherapy.
    • Correlate the clinical response to immunotherapy with the mobilization of lymphocytes from the tumor (tumor-specific clonotypes – TcR-seq) to peripheral blood after treatment.
    • To evaluate microbiome composition and functional/metabolic profile at baseline and/or changes from baseline and their correlation with clinical outcomes of therapy.
    The endpoints for assessment the safety of durvalumab and tremelimumab will include the rate of adverse events (AEs) and serious adverse events (SAEs).
    Los criterios de evaluación secundarios para evaluar la actividad antitumoral son:
    • Actividad antitumoral de durvalumab y durvalumab + tremelimumab en el CCR/CE con MSS y el CCR/CE con MSI, de acuerdo a las siguientes determinaciones adicionales:
    o Duración de la respuesta (DR), definida como el tiempo transcurrido desde la respuesta inicial del tumor hasta la progresión de la enfermedad.
    o Supervivencia libre de progresión (SLE), definida como el tiempo transcurrido desde el inicio del tratamiento hasta la progresión de la enfermedad o el fallecimiento.
    o Supervivencia global (SG), definida como el tiempo transcurrido desde el inicio del tratamiento hasta el fallecimiento.
    o Tiempo de respuesta máxima (TTMR), definido como el tiempo transcurrido desde el inicio del tratamiento hasta la máxima respuesta documentada en TAC.
    o Tasa de respuesta inmunitaria (irRR), siguiendo la definición de iRECIST con el uso de una medida unidimensional.
    • Seguridad de durvalumab y durvalumab + tremelimumab en la cohorte de pacientes incluidos en el ensayo.
    • Estudio transcriptómico de células individuales de los tumores al inicio y tras tratamiento con inmunoterapia, incluyendo el tiempo de máxima respuesta, y en el momento de progresión de la enfermedad.
    • Relacionar la actividad antitumoral de durvalumab y durvalumab + tremelimumab con otros biomarcadores en tejido tumoral y muestras de sangre.
    Los criterios de valoración empleados para la evaluación de biomarcadores en tejido tumoral y sangre periférica son:
    Biomarcadores genómicos e inmunológicos:
    • Relacionar la respuesta clínica a inmunoterapia con el transcriptoma completo, medido a nivel de célula individual y mediante secuenciación de ARN en condiciones basales, tras el tratamiento, en el momento de máxima respuesta, en el momento de progresión y en caso de inmunotoxicidad.
    • Establecer la relación entre la respuesta clínica a inmunoterapia y la secuenciación de ADN, secuenciación de ctADN, secuenciación masiva dirigida de ADN, secuenciación ATAC y secuenciación del exoma.
    • Predecir los neoantígenos tumorales de cada paciente a partir del análisis del mutanoma (secuenciación del ARN y del exoma) y establecer su relación con la respuesta clínica a inmunoterapia.
    • Establecer la relación entre la respuesta clínica a inmunoterapia y la movilización de linfocitos desde el tumor (clonotipos específicos del tumor - secuenciación de TcR) a la sangre periférica tras el tratamiento.
    • Evaluar la composición del microbioma y el perfil funcional y metabólico en condiciones basales y/o los cambios desde la situación basal y su correlación con los resultados clínicos de la terapia.
    Los criterios de evaluación para evaluar la seguridad de durvalumab y tremelimumab serán la tasa de acontecimientos adversos (AA) y de acontecimientos adversos graves (AAG).
