Bayesian Dose Adjustment of Immunosuppressants After Lung Transplantation (BASALT)

Gedetailleerde beschrijving
This research will be based on a prospective randomized trial comparing optimized TDM of tacrolimus and MMF to the current strategy of tacrolimus and MMF dose adjustment in lung transplant recipients. The study will focus on the first three years post-transplantation, as treatment failures (including BOS) occur mainly during this post-transplantation period. As the aim of tacrolimus and MMF dose individualization is to avoid over- or underexposure, for the purpose of this study treatment failure will be a composite criterion gathering events which reflect both over- and underexposure to tacrolimus and MMF.
Optimized TDM of tacrolimus and MMF based on blood tacrolimus and plasma MPA AUC Bayesian estimation will be compared to current strategies: tacrolimus dose adjustment based on trough levels (C0) and administration of a standard dose of MMF, decreased by the pulmonologist in case of adverse drug reactions or increased in case of inefficacy. The efficacy of optimized strategy vs. current strategies will be mainly evaluated through the incidence of treatment failure.
