简要总结
This is a 12-month single center, randomized, open-label, single center study designed to compare the safety and efficacy of everolimus and very low dose tacrolimus versus enteric-coated sodium mycophenolate and low tacrolimus exposure in de novo kidney transplant recipients.
The purpose of this study is to compare safety and efficacy of two immunosuppressive regimens based on low tacrolimus exposure combined to everolimus or to enteric-coated mycophenolate sodium (EC-MPS) in de novo kidney transplant recipients.
详细描述
The study will consist of two periods: an initial period of 3 months during which all patients in both groups will be monitored in accordance with the same variation of C-0h tacrolimus and a second study period of 9 months (from month 4 to month 12) in which patients will be monitored according to two different targets of C-0h tacrolimus.
At the screening visit and before any assessment related to the study, patients must give their informed consent in writing.
All patients will receive induction with rabbit Thymoglobulin (r-ATG) in four doses of 1.5 mg/kg (maximum total dose of 6 mg/kg), administered according to center local practice.
The evaluations of baseline visit occur within 24 hours after transplantation and prior to the first dose of study drug.
Randomization will be performed within 24 hours after transplantation and after the baseline visit assessments. Patients will be randomized in a 1:1 ratio to one of two groups (everolimus with very low dose of tacrolimus versus sodium mycophenolate with low dose of tacrolimus).
