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 realizará investigaciones biomédicas futuras en muestras de ADN (sangre) recogidas durante este ensayo clínico. Esta investigación consiste en un estudio de biomarcadores para estudiar aspectos que no estén descritos en el protocolo (como parte del estudio principal) y sólo se realizarán en los pacientes que hayan consentido. El objetivo de la recogida de muestras para investigación biomédica futura es explorar e identificar biomarcadores que ayuden a entender las enfermedades y sus tratamientos. El objetivo global es utilizar dicha información para desarrollar medicamentos más seguros y efectivos y asegurar que los pacientes reciben la dosis correcta de medicación en el momento correcto.
    E.3Principal inclusion criteria
    1.be > or = to 18 years of age on day of signing informed consent.

    4.have liver disease staging assessment as follows:
    Cirrhosis is defined as any one of the following [16,17]:
    -A liver biopsy performed prior to Day 1 of this study showing cirrhosis (F4)
    -Fibroscan performed within 12 calendar months of Day 1 of this study showing cirrhosis with result >12.5 kPa [17]*
    -A FibroSure® (Fibrotest®)performed during Screening with a score of >0.75 and an aspartate aminotransferase (AST):platelet ratio index (APRI) of >2. APRI formula: AST÷lab upper limit of normal (ULN) for AST x 100÷{platelet count÷100} (APRI calculation to be provided by the central laboratory.)
    Absence of cirrhosis is defined as any one of the following:
    -Liver biopsy performed within 24 months of Day 1 of this study showing absence of cirrhosis
    -Fibroscan performed within 12 months of Day 1 of this study with a result of < or = to 12.5 kPa[17]*
    -A FibroSure® (Fibrotest®)score of < or = to 0.48 and Aspartate Aminotransferase to Platelet Ratio Index (APRI) of 1 during Screening
    In the absence of a definitive diagnosis of presence or absence of cirrhosis by the above criteria, a liver biopsy is required. Liver biopsy results supersede the results obtained by Fibroscan or FibroSure®.
    5.have received a prior regimen containing an approved DAA (boceprevir, telaprevir, simeprevir, or sofosbuvir) co-administered for at least 4 weeks with PR (note: due to the 4 week PR lead-in for boceprevir, a subject would meet this criterion after 8 weeks on this regimen). If prior to the approved DAA + PR containing regimen, the subject received a regimen only containing ribavirin and/or interferon(i.e., PR or interferon alone; unaccompanied by a DAA), this is also permitted.
    Subjects HCV treatment history (i.e., type of therapy and duration of therapy) and reason for discontinuation of prior treatment (i.e., virologic failure, safety/tolerability, or administrative reasons) should be available.
    Subjects that discontinued prior therapy due to virologic failure must have met one of the following definitions:
    -PR+DAA Nonresponder: HCV RNA detected at end of treatment with a regimen that included one HCV DAA dosed in combination with PR. Subject must not have had undetectable HCV RNA during treatment. Can include subjects who met protocol-defined virologic futility rule (except for breakthrough, which is captured elsewhere).
    -PR+DAA Breakthrough: Confirmed increase in HCV RNA > or = to LLoQ after HCV RNA previously declined to < LLOQ. Occurred during the DAA dosing period with a regimen that included one DAA dosed in combination with PR.
    -PR+DAA Tail Breakthrough: Confirmed increase in HCV RNA > or = to LLoQ after HCV RNA previously declined to <LLoQ. Occurred during the PR tail dosing period that followed a PR + DAA dosing period.
    -PR+DAA Relapser: HCV RNA undetectable (TND) at end of treatment with a regimen that included oneDAA dosed in combination with PR, but HCV RNA quantifiable (LLoQ) during follow-up

    -Positividad para anticuerpos anti-VHC, ARN del VHC o un genotipo del VHC al menos 6 meses antes de la selección, o
    -Positividad para anticuerpos anti-VHC o ARN del VHC en el momento de la selección con una biopsia hepática compatible con infección crónica por el VHC (o una biopsia hepática realizada antes de la inclusión con datos de hepatitis C crónica [HCC], como la presencia de fibrosis).
    4.Disponer de una evaluación del estadio de la hepatopatía:
    La presencia de cirrosis se define por cualquiera de las circunstancias siguientes [16,17]:

    -Evaluación mediante FibroSure® (Fibrotest®) realizada durante la selección con una puntuación > 0,75 y un índice de aspartato aminotransferasa (AST): plaquetas (APRI) > 2. Fórmula APRI: AST÷límite superior de la normalidad (LSN) del laboratorio para la AST x 100 ÷ {recuento de plaquetas ÷ 100} (el cálculo del APRI será facilitado por el laboratorio central.)
    La ausencia de cirrosis se define como cualquiera de las circunstancias siguientes:
    -Biopsia hepática practicada en los 24 meses anteriores al día 1 de este estudio que indique ausencia de cirrosis.
    -Evaluación mediante Fibroscan realizada en los 12 meses anteriores al día 1 de este estudio con un resultado < or = to 12,5 kPa [17]*.*
    -Puntuación FibroSure® (Fibrotest®) < or = to 0,48 e índice de aspartato aminotransferasa/plaquetas (APRI) < or = to 1 durante la selección.

    Los sujetos que dejaron de recibir el tratamiento previo por fracaso virológico han de haber cumplido una de las definiciones siguientes:
    -Sin respuesta a PR±AAD: concentración detectable de ARN del VHC al final de un régimen que incluyera un AAD contra el VHC en combinación con PR. El sujeto no podrá haber tenido una concentración indetectable de ARN del VHC durante el tratamiento. Pueden incluirse los sujetos que cumplieron el criterio de inutilidad virológica definido en el protocolo (excepto recaída, que se recoge en otra definición).
    -Recaída con PR±AAD: aumento confirmado de la concentración de ARN del VHC > o = a LIC tras una disminución previa por debajo del LIC, ocurrido durante el periodo de administración del AAD en régimen que incluyera un AAD en combinación con PR.
    -Recaída tardía con PR±AAD: aumento confirmado de la concentración de ARN del VHC > o = a LIC tras una disminución previa por debajo del LIC, ocurrido durante el tramo final de tratamiento con PR que sigue al periodo de administración de PR + AAD.
    -Recidiva con PR±DAA: concentración de ARN del VHC indetectable (OND) al final del tratamiento con un régimen que incluyera un AAD en combinación con PR, pero cuantificable (> o = a LIC) durante el período de seguimiento
