E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The main objective is to observe a significant improvement in DFG (clearance calculated according to the CKD EPI formula) of 20 ml/min between M3 and M12 post TC, in cardiac transplant patients at risk of CKD, treated with 9 monthly infusions of belatacept associated with a progressive decrease in calcineurin inhibitors. |
L'objectif principal est d'observer une amélioration significative du DFG (clairance calculée selon la formule CKD EPI) de 20 ml/min entre M3 et M12 post TC, chez des transplantés cardiaques à risque d'IRC, traités par 9 perfusions mensuelles de belatacept associé à une diminution progressive des inhibiteurs de calcineurine. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives are:
Demonstrate that if there is a risk of rejection (> grade 2) it is less than 30% during the first year of the heart transplant as found in the literature (non-inferiority criterion)
Quantify the percentage of patients developing NODAT (New Onset Diabetes After Transplantation) at M3 and M12 post-TC (Estimate).
Evaluate the mortality specific to M12 post TC (Estimate).
Evaluate the use of renal replacement therapy between M3 and M12 post-TC. |
Les objectifs secondaires sont :
Démontrer que s’il existe un risque de rejet (> grade 2) celui-ci est inférieur à 30% au cours de la première année de la transplantation cardiaque comme retrouvé dans la littérature (critère de non-infériorité)
Quantifier le pourcentage de patients développant un NODAT (New Onset Diabetes After Transplantation) à M3 et M12 post TC (Estimation).
Evaluer la mortalité spécifique à M12 post TC (Estimation).
Evaluer le recours à un traitement de suppléance rénale entre M3 et M12 post TC.
