A Clinical Trial to Assess the Efficacy and Safety of the Conversion to Everolimus

Phase 4
Conditions
Kidney Transplant Recipients
Interventions
Registration Number
NCT01608412
Lead Sponsor
Hospital de Clinicas de Porto Alegre
Brief Summary

The study hypotheses to be tested in this study are:

* Conversion to everolimus at 3 months post-transplantation is safe and effective;

* Accurate noninvasive molecular diagnostic tests can replace biopsy at 3 months pre-conversion (for the diagnosis of subclinical cellular and/or humoral rejection, tissue fibrosis and calcineurin inhibitor-induced nephrotoxicity) in kidney transplant recipients;

* Follow-up biopsy at 12 months post-conversion (for the diagnosis of tissue fibrosis) can be replaced with accurate noninvasive molecular diagnostic tests in kidney transplant recipients.

GroupInterventionDescription
TacrolimusTacrolimusThe subjects included in the study will be clinically followed up for at least 12 months. The patients will be selected at 3 months post-transplant according to inclusion and exclusion criteria and randomized in a 1:1 ratio for conversion to everolimus or maintenance of tacrolimus therapy. Intervention arm: Tacrolimus
EverolimusEverolimusThe subjects included in the study will be clinically followed up for at least 12 months. The patients will be selected at 3 months post-transplant according to inclusion and exclusion criteria and randomized in a 1:1 ratio for conversion to everolimus or maintenance of tacrolimus therapy. Intervention arm: Everolimus
Primary Outcome Measures
NameTimeMethod
Evaluate cumulative patient and graft survival at 12 months post conversionone year

Patient and graft survival will be evaluated one year after randomization by Kaplan-Meier analysis

Secondary Outcome Measures
NameTimeMethod
Evaluation of estimated glomerular filtration rate 12 months post-conversionone year

- To assess the efficacy of conversion from tacrolimus to everolimus 12 months post-conversion by measuring the estimated glomerular filtration rate using the Modification of Diet in Renal Disease (MDRD) equation
