  Purpose

Background Early conversion from calcineurin inhibitor to mammalian target of rapamycin inhibitor is one of the immunosuppressive strategies that have been investigated to mitigate long-term CNi associated adverse events. This study aims to evaluate the conversion from tacrolimus to sirolimus in de novo kidney transplant recipients.

This multicenter, open-label study, planned to enroll 297 patients initially treated with tacrolimus, enteric-coated mycophenolate sodium (1440 mg/day, orally) and prednisone. The primary objective is to show superior glomerular filtration rate in the SRL group at 24 months after transplantation.


Condition Intervention Phase
Kidney Transplant Drug: Conversion from Tacrolimus to Sirolimus Drug: Maintenance on tacrolimus Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Outcomes of Planned Conversion From Tacrolimus to Sirolimus-based Immunosuppressive Regimen in de Novo Kidney Transplant Recipients
