E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objectives of this study are to assess the following in pediatric subjects with congenital or acquired heart disease requiring chronic prophylactic anticoagulation: *the safety of apixaban *apixaban PK, PD (by measuring FX using chromogenic assay), and anti-FXa activity *the effects of apixaban versus VKA antagonists or LMWH on QOL measures *the efficacy of apixaban for thromboprophylaxis *biomarkers that may reflect anticoagulant efficacy or risk of thrombosis |
Los objetivos de este estudio son evaluar siguientes parámetros en pacientes pediátricos con cardiopatías congénitas o adquiridas que requieran anticoagulación profiláctica crónica: * La seguridad de apixaban * FC, FD de apixaban (mediante la determinación del FX usando el ensayo cromogénico) y actividad anti-FXa * Los efectos de apixaban frente a AVK o HBPM en las medidas de la CdV * La eficacia de apixaban en la tromboprofilaxis * Los biomarcadores que pueden reflejar la eficacia anticoagulante o el riesgo de trombosis |

La hemorragia CRNM se define como hemorragia que satisface uno o ambos de los siguientes criterios: •hemorragia manifiesta para la cual se administra el producto sanguíneo y no directamente atribuible a la enfermedad clínica subyacente del sujeto •hemorragia que requiere intervención médica o quirúrgica para restablecer la hemostasia, excepto en una sala de operaciones |
