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   43858   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.5 End points
    E.5.1Primary end point(s)
    Part A:
    The co-primary endpoints for the comparison between the 2 AT13387 regimens are as follows:
    ? Incidence and severity of AEs and DLTs using National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4 to assess safety and
    ? Response rate assessed based on achieving any one or more of the following:
    o Complete response (CR) with disappearance of target lesions or partial response (PR) with 30% decrease in change of sum of longest diameters of target lesions according to modified RECIST 1.1.
    o PSA response defined as ?50% decrease in PSA at 12 weeks according to PCWG2 criteria in the absence of skeletal and extraskeletal progression. PSA decline must be confirmed to be sustained by a second PSA value obtained 4 or more weeks later.
    o Conversion of CTC count defined as decline in CTC count from ?5 cells/7.5 mL of blood to <5 cells/7.5 mL of blood, or a 30% decrease in CTC count from baseline in the absence of skeletal or extraskeletal progression.

    Part B:
    The primary endpoint for Part B is response rate assessed as in Part A.
    Los criterios de valoración principales para comparar las dos pautas posológicas de AT13387 son los siguientes:
    ? Incidencia e intensidad de los AA y las TLD, empleando la versión 4.0 de los criterios terminológicos comunes para la evaluación de las reacciones adversas del instituto estadounidense del cáncer (CTCAE-NCI, National Cancer Institute Common Terminology Criteria for Adverse Events).
    ? Índice de respuestas evaluado por la consecución de uno o más de los siguientes casos:
    o Respuesta completa (RC), con desaparición de las lesiones seleccionadas o respuesta parcial (RP) con una disminución del 30 % en la variación de la suma de los diámetros mayores de las lesiones seleccionadas, de acuerdo con los RECIST 1.1 modificados.
    o Respuesta de los APE definidos como disminución ? 50 % de los APE a las 12 semanas, de acuerdo con los criterios del PCWG2 sin progresión a nivel óseo ni extraóseo. Debe confirmarse la disminución de los APE con la confirmación de un segundo valor de APE obtenido a las 4 semanas o más tarde.
    o Conversión del recuento de CTC, definida como una disminución en el recuento de CTC de < 5 células/7,5 ml de sangre hasta < 5 células/7,5 ml de sangre o una disminución del 30 % en el recuento de CTC desde el inicio y sin progresión a nivel óseo o extraóseo.

    Parte B:
    El criterio de valoración principal de la Parte B es el índice de respuesta, evaluado de igual modo que en la Parte A.
    E.5.1.1Timepoint(s) of evaluation of this end point
    In Part A, a total of 14 evaluable subjects will be randomized to each regimen at the MTD. The absence of at least 1 response in 14 subjects in any of the arms will indicate an antitumor activity in that arm of <20% with 95% confidence; that arm will not proceed to Part B evaluation.
    En la Parte A se randomizará a un total de 14 pacientes evaluables a cada tratamiento con la DMT. La ausencia de 1 respuesta como mínimo de los 14 pacientes de cualquiera de los grupos indicará una actividad antineoplásica en dicho grupo inferior al 20 %, con un intervalo de confianza del 95 %. En ese caso, ese grupo no pasará a la evaluación de la Parte B.
    E.5.2Secondary end point(s)
    Part A:
    ? Pharmacokinetic parameters (maximum concentration [Cmax], area under the curve [AUC], and other secondary pharmacokinetic parameters) of AT13387 and abiraterone;
    ? Depletion of AR and other client proteins in CTCs and/or in tumor tissue to assess biological activity and pharmacodynamics;
    ? PFS (progression defined per PCWG2 recommendations); and
    ? OS.

    E.5.2.1Timepoint(s) of evaluation of this end point
    At the end of Stage 2 (35 subjects per arm), at least 7 responses should be observed in either arm to declare positive antitumor activity in that arm. If both arms succeed in Stage 2, a total of at least 56 subjects per arm will be randomized in order to compare antitumor activity between the 2 arms.
    Cuando finalice la etapa 2 (35 pacientes por grupo), se deberán haber observado un mínimo de 7 respuestas en cada grupo para poder afirmar que existe actividad antineoplásica en dicho grupo. Si los dos grupos consiguen el objetivo en la etapa 2, se randomizará a un total de 56 pacientes como mínimo a cada grupo para comparar la actividad antineoplásica entre los dos grupos de tratamiento.
