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   43871   clinical trials with a EudraCT protocol, of which   7290   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.

    MedDRA Classification
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The main objective is to prospectively explore the potential for long-term retention of Gadolinium in the bones of patients who have received a single dose of Gadolinium containing Contrast Agent (GdCA) or multiple doses of the same GdCA, with moderate or severe renal impairment or stable renal function (estimated glomerular filtration rate > 60 ml/min/1.73 m²) at the time of GdCA injection.
    Explorar de forma prospectiva la posibilidad de retención a largo plazo del Gd en los huesos de los pacientes que han recibido una única dosis de MC-Gd o múltiples dosis del mismo MC-Gd, con insuficiencia renal moderada o grave o función renal estable (tasa de filtración glomerular estimada > 60 ml/min/1,73 m2) en el momento de la inyección de MC-Gd
    E.2.2Secondary objectives of the trial
    The secondary objectives are
    - to evaluate skin samples for concentration of Gd,
    - to evaluate bone and skin samples for concentrations of calcium, phosphorus, sodium, iron, zinc and potassium
    - to evaluate skin samples for any dermatopathological changes that may be associated with Nephrogenic Systemic Fibrosis (NSF)
    - to describe potential co-factors for NSF, susceptibility factors and drug treatments with potential impact on bone metabolism
    - Evaluar la concentración de Gd en muestras de piel.
    - Evaluar la concentración de calcio, fósforo, sodio, hierro, zinc y potasio en muestras de hueso y piel.
    - Evaluar cualquier cambio dermopatológico que pueda asociarse a fibrosis sistémica nefrogénica (FSN) en muestras de piel.
    - Describir posibles cofactores para la FSN, factores de sensibilidad y tratamientos farmacológicos con posible influencia sobre el metabolismo óseo.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Patient must be at least 18 years of age (or older if required by local regulations)
    2. Patient scheduled for hip or knee replacement
    3. Patient is scheduled to have sufficient bone removed during the hip or knee surgical replacement procedure and sufficient non-scarred skin tissue from the edge of the surgical incision to permit sample collection, in the investigator?s medical opinion
    4. Patient agreed to have bone and skin samples collected at the time of the surgical procedure(s)
    5. Patient?s surgical procedure and subsequent remission will not be altered by study-specific skin biopsies, in the investigator?s medical opinion

    or
    c) patient (total to enrol = 5) has stable moderate renal impairment (eGFR within the range 30 to 60 ml/min/1.73 m²) and has received one GdCA injection at the standard dose (0.025 mmol per kg body weight for Gadoxetic acid and 0.1 mmol per kg body weight for all other agents)
    or
    d) patient (total to enrol = 5) has stable moderate renal impairment (eGFR within the range 30 to 60 ml/min/1.73 m²) and has received more than one injection of the same GdCA
    or
    e) patient (total to enrol = 5) has stable renal function (eGFR > 60 ml/min /1.73 m²) and has received one GdCA injection at the standard dose (0.025 mmol per kg body weight for Gadoxetic acid and 0.1 mmol per kg body weight for all other agents)
    or
    f) patient (total to enrol = 5) has stable renal function (eGFR > 60 ml/min /1.73 m²) and has received more than one injection the same GdCA.
