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   43861   clinical trials with a EudraCT protocol, of which   7284   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 Objective of the trial
    E.2.1Main objective of the trial
    • Biological objective: To characterize the molecular patterns of resistance [with a special focus on retinoblastoma (Rb) status] upon progression to palbociclib plus endocrine therapy in patients who previously achieved clinical benefit with the combination. The biological markers analysed must cover the entire CDK4/6-Cyclin D-Rb axis, including Cyclin D and E, as the latter appears to play an important role in the mechanism of resistance to palbociclib.
    • Clinical objective: To define the clinical activity of the combination of palbociclib and endocrine therapy after prior progression to palbociclib in endocrine-sensitive patients.
    • Objetivo biológico: caracterizar los patrones moleculares de resistencia (centrándose especialmente en el estado del retinoblastoma [Rb]) tras la progresión a tratamiento con palbociclib y terapia endocrina en pacientes que previamente hayan alcanzado beneficio clínico con la combinación. Los marcadores biológicos analizados deben abarcar todo el eje de CDK4/6-ciclina D-Rb, incluyendo ciclina D y E, ya que esta última parece desempeñar un papel importante en el mecanismo de resistencia a palbociclib.
    • Objetivo clínico: definir la actividad clínica de la combinación de palbociclib y terapia endocrina después de la progresión al tratamiento con palbociclib en pacientes sensibles a la terapia endocrina.
    E.2.2Secondary objectives of the trial
    - To correlate clinical activity with molecular patterns of resistance.
    - To characterize changes of immunostaining of Rb targets (E2F, DNMT, HIF1alpha, and SKP2) as a result of CDK4 and CDK6 inhibition and the potential predictive value of cyclin D, cyclin E, p16, p18, p21, and p27, in CDK4, and CDK6 inhibition.
    - To characterize the senescence and apoptosis (Ki67 and active caspase 3) in subgroups of patients with varying clinical responses.
    - To collect data about differences in expression profile, assessed by RNA microarrays.
    - To estimate the correlation between inhibitory effects of palbociclib and clinical response.
    - To assess the safety and tolerability of the combination of palbociclib plus endocrine therapy after previous treatment with palbociclib plus endocrine therapy.
    - To analyse the correlation between inhibitory effects of palbociclib and clinical response in patients with visceral disease or patients who received prior (neo) adjuvant hormonal therapy.
    -Correlacionar la actividad clínica con patrones moleculares de resistencia.
    -Caracterizar los cambios de inmunotinción de las dianas Rb (E2F, DNMT, HIF1alfa y SKP2) como resultado de la inhibición de CDK4 y CDK6 y el valor predictivo potencial de la ciclina D, ciclina E, p16, p18, p21 y p27 en la inhibición de CDK4 y CDK6.
    -Caracterizar la senescencia y apoptosis (Ki67 y caspasa activa 3) en los subgrupos de pacientes con diferentes respuestas clínicas.
    -Recoger datos sobre las diferencias en el perfil de expresión, evaluado mediante micromatrices de ARN.
    -Estimar la correlación entre efectos inhibitorios de palbociclib y respuesta clínica.
    -Evaluar la seguridad y tolerabilidad de combinación de palbociclib y terapia endocrina después del tto. previo con palbociclib y terapia endocrina.
    -Analizar correlación entre efectos inhibitorios de palbociclib y respuesta clínica en pacientes con enfermedad visceral o pacientes que hayan recibido terapia hormonal (neo) adyuvante previa.

    E.5 End points
    E.5.1Primary end point(s)
    This trial has two primary endpoints: a biological endpoint and a clinical endpoint.
    From a biological point of view, the primary endpoint of this study is the percentage of patients with Rb loss [as defined by loss of expression, copy number variation (CNV), somatic mutation, or methylation dependent silencing]. The evaluation criteria will be the characterization of the molecular patterns of resistance with greater than 20% prevalence.
    From a clinical point of view, the primary endpoint for this study is the percentage of patients that achieve clinical benefit (CBR) defined as complete response, partial response, or stable disease for at least 24 weeks per RECIST v.1.1.
    Este ensayo tiene dos variables principales, una variable biológica y una variable clínica.
    Desde el punto de vista biológico, la variable principal de este estudio es el porcentaje de pacientes con pérdida de Rb (definida como la pérdida de expresión, variación en el número de copias [VNC], mutación somática o silenciamiento dependiente de la metilación). Los criterios de evaluación serán la caracterización de los patrones moleculares de resistencia con una prevalencia superior al 20 %.
    Desde el punto de vista clínico, la variable principal de este estudio es el porcentaje de pacientes que alcanzan un beneficio clínico (TBC) definido como respuesta completa, respuesta parcial o enfermedad estable durante al menos 24 semanas según los criterios RECIST v.1.1.
    E.5.1.1Timepoint(s) of evaluation of this end point
    Baseline up to 2 years.
    Durante máximo 2 años desde valor basal.
    E.5.2Secondary end point(s)
    Efficacy:
    • Overall response rate (ORR).
    Molecular objectives:
    • To measure histoscore (Hscore) levels of the following targets:
    - Cyclin D, cyclin E, p16(Ink4a), p18(Ink4c), p21, and p27.
    - Other pRb pathway’s targets (E2F, DNMT, HIF1alpha, and SKP2).
    - Markers of proliferation and apoptosis (active caspase 3).
    • To collect data about the differences in expression profiles, assessed by RNA microarrays.
    Safety:
    Patient safety and adverse events (AEs) will be assessed using the NCI CTCAE v.4.0.3. Grade 3 and 4 AEs and serious adverse events (SAEs) will be assessed to determine the safety and tolerability of the different drug combinations.
    Eficacia:
    • Tasa de respuesta global (TRG)
    Objetivos moleculares:
    • Medir la puntuación inmunohistoquímica (Hscore) de las siguientes dianas:
    - Ciclina D, ciclina E, p16(Ink4a), p18(Ink4c), p21 y p27.
    - Otras dianas de la vía de pRb (E2F, DNMT, HIF1alfa y SKP2).
    - Marcadores de proliferación y apoptosis (caspasa activa 3).
    • Recoger datos sobre las diferencias en los perfiles de expresión, evaluados mediante micromatrices de ARN.
    Seguridad:
    La seguridad y los acontecimientos adversos (AA) de las pacientes se evaluarán según los CTCAE v.4.0.3 del NCI. Se evaluarán los AA de grado 3 y 4 y los acontecimientos adversos graves (AAG) para determinar la seguridad y tolerabilidad de las distintas combinaciones de fármacos.
