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   44334   clinical trials with a EudraCT protocol, of which   7366   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
    Safety Run-in, Arm 1, Arm 2:
    To determine the recommended dose of siremadlin in combination with venetoclax plus azacitidine to be explored further in the expansion phase (RDE), separately in Arm 1 and Arm 2.
    Safety Run-in and expansion, Arm 1:
    To evaluate preliminary efficacy of siremadlin at the determined recommended dose for expansion (RDE) when administered in combination with venetoclax plus azacitidine in achieving Complete Remission (CR) (Arm 1 only).
    Preinclusión de seguridad, grupos 1 y 2:
    Determinar la dosis recomendada de siremadlin en combinación con venetoclax más azacitidina. Esto se debe evaluar más a fondo en la fase de expansión (DRE), por separado en los grupos 1 y 2.
    Preinclusión de seguridad y expansión, grupo 1:
    Evaluar la eficacia preliminar de siremadlin en la dosis recomendada para la expansión (DRE) que se haya determinado cuando se administra en combinación con venetoclax más azacitidina para alcanzar la remisión completa (RC). (Solo grupo 1)
    E.2.2Secondary objectives of the trial
    1. safety and tolerability profile of siremadlin when administered in combination with venetoclax plus azacitidine (Arms 1 and 2).
    2. CR rate (Arm 2 only; for Arm 1, assessment of CR is a primary endpoint).
    3. duration of CR in Arm 1 as well as in Arm 2.
    4. CR/CRh and CR/CRi rates with CRh defined as CR with partial hematological recovery (neutrophils > 0.5 X109/L and platelet > 50X109/L) and CRi defined as CR with incomplete hematological recovery (neutrophils <1.0X109/L and/or platelets <100X109/L) (Arm 1 and 2).
    5. duration of CR/CRh and CR/CRi (Arm 1 and 2).
    6. Overall Survival (OS) (Arm 1 and 2).
    7. Assessment of early mortality, defined by 30- and 60- day mortality from the start of study treatment (Arm 1 and 2).
