Overview
Brief Summary
This study is a multicenter, randomized, comparison, open-label, phase IV study in kidney transplant recipients whose immunosuppressive regimen is converted from Cyclosporine with corticosteroid to Advagraf® with corticosteroid. The eligible patients will be randomized into either Arm 1 or Arm 2. The Arm 1 will be reduced corticosteroid slowly until 50% lower dose from 4 weeks to 12 weeks in the Advagraf®-based immunosuppressive regimen, and the Arm 2 will receive the same corticosteroid dose for 24 weeks with Advagraf ®.
Detailed Description
The primary objective is to assess the changes in the GFR after 24 weeks of treatment between the group that was reduced corticosteroid slowly until 50% lower dose from 4 weeks to 12 weeks and the group with maintained corticosteroid in stable kidney transplant subjects whose regimen was converted from a CyA-based immunosuppressive regimen with corticosteroid to an Advagraf®-based immunosuppressive regimen with corticosteroid for kidney transplant subjects whose regimen was converted from a CyA-based immunosuppressive regimen. The secondary objective is to assess the creatinine clearance rate, acute rejection, satisfaction of medication and safety of the group with a 50% reduced dose of corticosteroid and the group in which the Advagraf ®-based immunosuppressive regimen with maintained corticosteroid.
