E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Demonstrate non-inferiority in terms of efficacy and safety (incidence of CMV disease over the first 6 months post-transplant) of a new strategy for prophylaxis against CMV inmunoguiada (based on systematic monitoring BMI) compared with the usual strategy of viremia guided prophylaxis (based on the early detection of viral replication and early treatment administration) in TR receivers intermediate risk (i.e. CMV seropositive at the time of transplantation (R) who have not received treatment depletor lymphocyte (ATG or muromonab)). |
Demostrar la no inferioridad en términos de eficacia y seguridad (incidencia de enfermedad por CMV a lo largo de los 6 primeros meses post-trasplante) de una nueva estrategia de profilaxis inmunoguiada frente al CMV (basada en la monitorización sistemática de la IMC) en comparación con la estrategia habitual de profilaxis guiada por viremia (basada en la detección precoz de la replicación viral y en la administración de tratamiento anticipado) en receptores de TR de riesgo intermedio (es decir, seropositivos frente a CMV en el momento del trasplante (R+) que no hayan recibido tratamiento con fármacos depletores linfocitarios (ATG o muromonab)). |
|
E.2.2 | Secondary objectives of the trial |
a) To compare the reliability and accuracy of different strategies of monitoring of the CMI response against CMV in the context of a strategy of immuno-guided prophylaxis in intermediate-risk KT recipients.
b) demonstrate the decrease in the number of episodes of asymptomatic CMV viremia and the total duration of the period of viral replication "permissive" (ie, low level and without direct clinical impact).
c) To demonstrate a decrease in the incidence of indirect effects attributable to CMV infection.
d) To demonstrate a decrease in the number of prescriptions and the duration of antiviral drugs use and the number of hospitalization episodes in those KT recipients undergoing a strategy of immunoguided prophylaxis against CMV, as compared to those undergoing a conventional strategy of viremia-guided prophylaxis.
e) To demonstrate a decrease in the incidence of adverse effects associated to such treatment in those KT recipients. |
a) Comparar la utilidad y precisión de varias técnicas de monitorización de la IMC en el contexto de una estrategia de profilaxis inmunoguiada frente a CMV en receptores de TR de riesgo intermedio.
b) Demostrar la disminución en el nº de episodios de viremia asintomática por CMV y la duración total de dicho periodo de replicación viral "permisiva" (es decir, de bajo nivel y sin repercusión clínica directa).
c) Demostrar un descenso enla incidencia de los efectos indirectos atribuibles a la infección por CMV.
d) Demostrar la disminución en el nº de prescripciones y en la duración del tratamiento antiviral y del número de episodios de hospitalización en los receptores de TR sometidos a una estrategia de profilaxis inmunoguiada frente a CMV, en comparación con la estrategia convencional de profilaxis guiada por viremia.
e) Demostrar la disminución en la incidencia de acontecimientos adversos atribuibles a dicho tratamiento antiviral en los receptores de TR. |
