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   43846   clinical trials with a EudraCT protocol, of which   7282   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.

    En relación con la evaluación por parte de las autoridades sanitarias de EE.UU., el objetivo principal del período 1 es evaluar la eficacia de tadalafilo, comparado con placebo, en términos de la mejoría observada en la semana 24, en relación con la distancia recorrida en la prueba 6MW en el momento basal, en un subconjunto de pacientes de ? 6 y < 18 años de edad, que sean capaces de realizar dicha prueba, desde el punto de vista del desarrollo.
    En relación con la evaluación por parte de las autoridades sanitarias de la UE, el objetivo principal del período 1 es evaluar la eficacia de tadalafilo, comparado con placebo, determinada por el tiempo transcurrido hasta el empeoramiento clínico, en el período comprendido hasta la semana 24, en niños con HAP.
    Periodo 2
    El objetivo principal del período 2 es evaluar la seguridad a largo plazo de tadalafilo, así como posibilitar que los niños con HAP que participaron en el período 1 continúen recibiendo tadalafilo.
    E.2.2Secondary objectives of the trial
    Period 1 secondary objectives:
    ? Assess the efficacy of tadalafil compared with placebo on time to CW (for the US regulatory assessment) and the incidence of CW.
    ? Assess the efficacy of tadalafil compared with placebo on 6-minute walk (6MW) distance in a subset of patients ?6 to <18 years of age who are developmentally capable of performing a 6MW test (for the EU regulatory assessment).
    ? Characterize the population PK of tadalafil in pediatric PAH patients.
    ? Assess the safety of tadalafil compared with placebo.

    Period 2 secondary objectives:
    ? The secondary objective of Period 2 is to evaluate the incidence of, and time to CW
    6.2.1. Periodo 1
    Los objetivos secundarios del período 1 son los siguientes:
    ? Evaluar la eficacia de tadalafilo, comparado con placebo, en relación con el tiempo transcurrido hasta el empeoramiento clínico (en relación con la evaluación por parte de las autoridades sanitarias de EE.UU.) y la incidencia de casos de empeoramiento clínico.
    ? Evaluar la eficacia de tadalafilo, en comparación con placebo, en relación con la distancia recorrida en la prueba 6MW, en un subconjunto de pacientes de edades ? 6 y < 18 años, que sean capaces de realizar dicha prueba, desde el punto de vista del desarrollo (en relación con la evaluación por parte de las autoridades sanitarias de UE).
    ? Caracterizar la farmacocinética (FC) poblacional de tadalafilo en niños con HAP.
    ? Evaluar la seguridad de tadalafilo, en comparación con placebo.
    6.2.2. Periodo 2
    El objetivo secundario del período 2 es evaluar la incidencia de casos de empeoramiento clínico, así como el tiempo transcurrido hasta el EC.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    [1] ?6 months to <18 years of age (at screening).
    [2] Currently have a diagnosis of PAH that is either:
    ?idiopathic, including hereditary;
    ?related to connective tissue disease;
    ?related to anorexigen use;
    ?associated with surgical repair of at least 6-month duration of congenital systemic to pulmonary shunt (eg, atrial septal defect, ventricular septal defect, patent ductus arteriosus)
    [3] Have a history of a diagnosis of PAH established by a resting mean pulmonary artery pressure (mPAP) ?25 mm Hg, pulmonary artery wedge pressure ?15 mm Hg, and a PVR ?3 Wood units via right heart catheterization (RHC). In the event that a pulmonary artery wedge pressure cannot be obtained during RHC, patients with a left ventricular end diastolic pressure (LVEDP) <15 mm Hg, with normal left heart function, and absence of mitral stenosis on echocardiography can be eligible for enrollment.
    [4] Have a WHO functional class value of II or III at the time of screening.
    [5] All subjects must be receiving an ERA (such as bosentan or ambrisentan) and must be on a maintenance dose with no change in dose (other than weight-based adjustments) for at least 12 weeks prior to screening and have a screening aspartate transaminase (AST)/alanine transaminase (ALT) <3 times the upper limit of normal (ULN).
    [6] If on conventional PAH medication, including but not restricted to, anticoagulants, diuretics, digoxin, and oxygen therapy, the patient must be on stable doses with no changes (other than weight-based adjustments) for at least 4 weeks before screening.
    [7] Female patients of childbearing potential must test negative for pregnancy during screening. Furthermore, female patients must agree to abstain from sexual activity or to use two different reliable methods of birth control as determined by the Investigator during the study. Examples of reliable birth control methods include true abstinence as a lifestyle choice (periodic sexual abstinence method is not acceptable); the use of oral contraceptives; a reliable barrier method of birth control (diaphragms with contraceptive jelly; cervical caps with contraceptive jelly; condoms with contraceptive foam; intrauterine devices).
    [8] Written informed consent from parents (and written assent from appropriately aged patients) will be obtained prior to any study procedure being performed.
    [1] Edad ? 6 meses y < 18 años (en el momento de la selección).
    [2] Diagnóstico actual de HAP, que cumpla alguno de los siguientes criterios:
    ? Sea idiopática, incluida la HAP de tipo hereditario;
    ? Esté relacionada con una enfermedad del tejido conectivo;
    ? Esté relacionada con el uso de anorexígenos;
    ? Esté asociada con una reparación quirúrgica de un cortocircuito sistémico-pulmonar simple congénito, de al menos 6 meses de duración (por ejemplo, comunicación interauricular, comunicación interventricular, conducto arterial persistente).
    [3] Antecedentes de diagnóstico de HAP, establecido basándose en unos valores de presión media en la arteria pulmonar (PAPm) en reposo ? 25 mm Hg, una presión de enclavamiento en la arteria pulmonar ? 15 mm Hg y una resistencia vascular pulmonar (RVP) ? 3 unidades de Wood, obtenidos mediante cateterismo del hemicardio derecho (CHD). En caso de que no pueda determinarse la presión de enclavamiento en la arteria pulmonar durante el cateterismo del hemicardio derecho, se considerarán idóneos para su reclutamiento en el estudio a aquellos pacientes que presenten una presión telediastólica en el ventrículo izquierdo (PTDVI) < 15 mm Hg, con función normal del hemicardio izquierdo y ausencia de estenosis mitral en la ecocardiografía.
