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   43881   clinical trials with a EudraCT protocol, of which   7295   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.

    D.8 Information on Placebo
    E. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Subclinical inflammation, including borderline lesions (BL), is very common after kidney transplantation (KT), even in low immunological risk patients, and can lead to interstitial fibrosis/tubular atrophy (IFTA) and worsening of renal function with graft loss. The aim of the study is to determine whether the treatment of early BL (3rd month post-KT) with Grafalon decreases the progression of IFTA and the worsening of graft function compared to conventional therapy after two years post-KT.
    La inflamación subclínica, es muy frecuente tras el trasplante renal (TX), aún en los pacientes de bajo riesgo inmunológico, y puede evolucionar a lesiones crónicas tipo fibrosis intersticial/ atrofia tubular (FIAT) y deterioro de la función renal. El objetivo es determinar si el tratamiento precoz de las lesiones borderline (3 m post-TX) con Grafalon disminuye la progresión de FIAT y deterioro de la función renal comparado con la terapia convencional después de dos años de seguimiento post-TX.
    E.1.1.1Medical condition in easily understood language
    The aim of the clinical trial is to study whether treatment of subclinical graft inflammation with grafalon improves kidney function and graft survival.
    El objetivo del ensayo clínico es estudiar si el tratamiento de la inflamación subclínica del injerto con grafalon mejora la función renal y la supervivencia del injerto.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    - To know in a randomized controlled clinical trial, carried out in patients with low immunological risk and stable renal function, if the treatment of BL lesions, detected in the third month post-transplantation, with rabbit polyclonal antilymphocytic globulin prevents or slows the progression of chronic histological graft lesions (FIAT) and the deterioration of its function compared to conventional clinical follow-up, after two years of post-transplant follow-up.

    - To analyze whether the anti-rejection treatment of borderline lesions can modify the expression and levels of klotho, as well as the pro-inflammatory cytokines that regulate the expression of klotho two years after transplantation.
    A) Conocer en un ensayo clínico controlado y randomizado, realizado en pacientes de bajo riesgo inmunológico y función renal estable, si el tratamiento de las lesiones BL, detectadas al tercer mes post-TX, con globulina policlonal antilinfocítica de conejo evita o disminuye la progresión de las lesiones histológicas crónicas del injerto (FIAT) y el deterioro de su función frente al seguimiento clínico convencional, tras dos años de seguimiento post-TX.

    B) Analizar si el tratamiento anti-rechazo de las lesiones BL puede modificar la expresión y los niveles de klotho, así como las citoquinas proinflamatorias que regulan la expresión de klotho a los dos años post-TX.
    E.2.2Secondary objectives of the trial
    A) Analyze and compare the incidence of immunological dysfunction (acute clinical and subclinical rejections) and the evolution of the histological findings in the two therapeutic arms.

    B) To know the relationship between α-klotho and acute clinical and subclinical rejection, as well as with the FIAT lesions in the two study arms.

    C) Evaluate the generation of donor-specific anti-HLA antibodies (DSA) in the two study groups.

    D) Investigate the impact of anti-rejection treatment on proteinuria during follow-up in both study arms.

    E) Know the relationship between urinary chemokine levels (CXCL9 and CXCL10) and subclinical inflammation in both arms of treatment.

    F)Evaluate graft and patient survival at the first and second year of follow-up.

    G) Analyze adherence to immunosuppressive treatment in the two treatment groups and its impact on chronic lesions (FIAT) and kidney function
    A) Analizar y comparar la incidencia de disfunción inmunológica (rechazos agudos clínicos y subclínicos) y la evolución de los hallazgos histológicos en los dos brazos terapéuticos.
    B) Conocer la relación entre α-klotho y rechazo agudo clínico y subclínico, así como con las lesiones de FIAT en los dos brazos de estudio.
    C) Evaluar la generación de anticuerpos anti-HLA específicos del donante (DSA) en los dos grupos de estudio.
    D) Investigar el impacto del tratamiento anti-rechazo sobre la proteinuria durante el seguimiento en ambos brazos de estudios.
    E) Conocer la relación entre los niveles de quimiocinas urinarias (CXCL9 y CXCL10) y la inflamación subclínica en ambas ramas de tratamiento.
    F) Evaluar la supervivencia del injerto y del paciente al primer y segundo año de seguimiento.
    G) Analizar la adherencia al tratamiento inmunosupresor en los dos grupos de tratamiento y su impacto sobre las lesiones crónicas (FIAT) y la función renal
    E.2.3Trial contains a sub-study Yes
