Primary Outcome Measures

Main Objective: To assess the safety of a tacrolimus modified release, MR4, based immunosuppressive regimen in stable kidney transplant subjects converted on a <br>1:1 (mg : mg) basis from a Prograf based immunosuppressive regimen. Non-inferiority for creatinine clearance will be assessed.;Secondary Objective: To assess the safety and efficacy of a tacrolimus modified release, MR4, based immunosuppressive regimen in stable kidney transplant subjects converted on a <br>1:1 (mg : mg) basis from a Prograf based immunosuppressive regimen. ;Primary end point(s): Change in creatinine clearance, calculated according to Cockcroft and Gault, between Prograf and MR4
