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   43870   clinical trials with a EudraCT protocol, of which   7289   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.5 End points
    E.5.1Primary end point(s)
    Primary Endpoints
    Phase 1
    ·Safety as determined by incidence of drug-related Grade ≥3 AEs or dose-limiting toxicities (DLTs) (if any) for each cohort dose/schedule.
    Phase 2
    ·Hematologic response as defined in the Efficacy Analysis section.
    Criterios de valoración primarios
    Fase 1
    - Seguridad determinada por la incidencia de AA de grado ≥3 relacionados con el fármaco o TLC (si las hubiera) para la dosis/pauta de cada cohorte.
    Fase 2
    - Respuesta hematológica según se define en la sección de análisis de la eficacia.
    E.5.1.1Timepoint(s) of evaluation of this end point
    The DSRC will comprise the principal investigators (or nominated deputies), medical monitor, study director, PD director, PK director, and other team members as appropriate. Safety, PD, and other clinical data from this study will be assessed for each dose cohort by the DSRC after at least Cycle 1 of Phase 1 Stage A and after at least Cycle 1 of Phase 1 Stage B. The DSRC will recommend the dose(s)/schedule(s) to be taken forward to Phase 2. In Phase 2, the DSRC will review emerging safety data in the first 6 subjects enrolled into the ASTX727 SD Daily×3 dose regimen and expand this safety evaluation to 12 subjects if necessary. The DSRC will also review the data when at least 20 subjects in each regimen have been followed up for at least 1 cycle of safety data, or earlier if warranted.
    El CVDS evaluará la seguridad, la FD y otros datos clínicos para cada cohorte de dosis después de los estadios A y B. Cuando todos los pacientes de cada cohorte tengan disponibles todos los datos del ciclo 1, el CVDS los revisará para seleccionar la(s) pauta(s) posológica(s) para pasar a la fase 2. En la fase 2, el CVDS revisará los datos de seguridad obtenidos de los primeros 6 pacientes incluidos en la pauta de ASTX727 SD en administración Diaria × 3 y, en caso necesario, ampliará dicha evaluación
    de seguridad a 12 pacientes. El CVDS también revisará los datos de seguridad cuando se haya seguido al menos a 20 pacientes de cada pauta posológica durante al menos 1 ciclo de datos de seguridad, o antes si se justifica.

    E.5.2.1Timepoint(s) of evaluation of this end point
    During the course of the study, emerging safety data will be considered by the DSRC in evaluating the potential risks and benefits of ASTX727 LD. In Phase 1, cohorts in which ≥33% of subjects are observed to have DLTs will stop further enrollment and not be taken forward to Phase 2. During the conduct of the study, cohorts may be discontinued from treatment with study drug for safety (including, but not limited to DLTs) after review by the DSRC.
    Durante el curso del estudio, el CVDS considerará los datos de seguridad emergentes al evaluar los riesgos y beneficios potenciales de ASTX727 LD. En la Fase 1, las cohortes en las que se observe que ≥33% de los sujetos tienen TLC detendrán la inscripción adicional y no pasarán a la Fase 2. Durante la realización del estudio, las cohortes pueden interrumpir el tratamiento con el fármaco del estudio por seguridad (incluyendo, pero no limitado a los TLC) después de la revisión por parte del CVDS.
