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.2.1Main objective of the trial
    The objective of this trial is the global risk-benefit assessment of Cerebrolysin as compared to donepezil in patients with mild to moderate dementia of Alzheimer type (DAT). In addition, a traditional approach will be taken based on an evaluation of the separate risk and benefit domains in comparison with donepezil
    El objetivo de este ensayo es evaluar el riesgo/beneficio global de la cerebrolisina en comparación con el donepecilo en pacientes con demencia de tipo Alzheimer (DTA) de leve a moderada. Además, se seguirá un enfoque tradicional en función de una evaluación de los dominios de riesgo y beneficio por separado en comparación con el donepecilo.
    E.2.2Secondary objectives of the trial
    Safety as compared to donepezil will be analyzed stand-alone by determining, whether the Cerebrolysin group shows non-inferiority with regard to the combined primary safety endpoints.
    Se analizará independientemente la seguridad en comparación con el donepecilo, determinando si el grupo de cerebrolisina muestra la no inferioridad con respecto a los criterios principales de valoración de seguridad combinados.

    E.5 End points
    E.5.1Primary end point(s)
    Global risk-benefit as compared to donepezil will be analyzed by determining whether the Cerebrolysin group shows a statistically significant non-inferiority with regard to the combined primary safety and efficacy endpoints (weighted multivariate ensemble).The endpoints will be combined by a global multivariate non-parametric procedure, weighting the safety and efficacy part 50:50 (regarding equally balancing risk and benefit see also O?Neill, FDA [O?Neill R 2008]). The individual weights are given as follows:
    Risk (relative sum of weight factors: 6)
    - (1) Proportion of patients with at least one AE during the main part of the study (Week 24), weight factor: 1
    - (2) Proportion of patients with at least one SAE during the main part of the study (Week 24), weight factor: 2
    - (3) Proportion of patients with premature discontinuation due to adverse event during the main part of the study (Week 24), weight factor: 3
    Benefit (relative sum of weight factors: 6)
    - (4) ADAS-cog changes Week 24, weight factor: 3
    - (5) CIBIC+ Week 24, weight factor: 3
    Thus, a total of 6 weighting points is given to the safety ensemble, and a total of 6 weighting points is also given to the efficacy ensemble, resulting in an overall 50:50 weighting of risk and benefit. This way, a combined and equally balanced global test for risk and benefit is obtained.
    The weighting of the safety endpoints within the multivariate safety ensemble is the same as described above for the global risk-benefit assessment (AE: weight factor 1, SAE: weight factor 2, premature discontinuation due to AE: weight factor 3).
    The multiple level alpha of the study (multiple level of significance) is defined as alpha = 0.025 (one-sided).
    Se analizará el riesgo/beneficio global en comparación con el donepecilo, determinando si el grupo de cerebrolisina muestra una no inferioridad estadísticamente significativa con respecto a los criterios principales de valoración de eficacia y seguridad combinados (conjunto de múltiples variables ponderadas). Los criterios de valoración se combinarán utilizando un procedimiento no paramétrico y de múltiples variables global, con ponderación para las partes de seguridad y eficacia 50:50 (con respecto al equilibrio equitativo del riesgo y beneficio, ver también O?Neill, FDA [O?Neill R 2008]).
    Los factores de ponderación individuales son los siguientes:
    Riesgo (suma relativa de los factores de ponderación: 6)
    -(1) Proporción de pacientes con al menos un AA durante el estudio (semana 24), factor de ponderación: 1
    -(2) Proporción de pacientes con al menos un AAG durante el estudio (semana 24), factor de ponderación: 2
    -(3) Proporción de pacientes con discontinuación anticipada debido a un acontecimiento adverso durante el estudio (semana 24), factor de ponderación: 3
    Beneficio (suma relativa de los factores de ponderación: 6)
    -(4) Cambios en ADAS-cog en la semana 24, factor de ponderación: 3
    -(5) CIBIC+ en la semana 24, factor de ponderación: 3
    Por lo tanto, se asigna un total de 6 puntos de ponderación al conjunto de seguridad y se asigna asimismo un total de 6 puntos de ponderación al conjunto de eficacia, produciendo una ponderación global 50:50 de riesgo y beneficio. De esta forma, se obtiene una prueba global combinada y equitativamente equilibrada del riesgo y beneficio.
    Además, se analizará independientemente la seguridad en comparación con el donepecilo, determinando si el grupo de cerebrolisina muestra la no inferioridad con respecto a los criterios principales de valoración de seguridad combinados. La ponderación de los criterios de valoración de seguridad dentro del conjunto de seguridad de múltiples variables es la misma que la anteriormente descrita para la evaluación global de riesgo/beneficio (AA: factor de ponderación 1, AAG: factor de ponderación 2, discontinuación prematura debido a AA: factor de ponderación 3).
    El valor alfa de niveles múltiples del estudio (nivel de significación múltiple) se define como alfa = 0,025 (unilateral).
