The purpose of this study is to confirm non-inferiority of delayed Prograf treatment to standard Prograf treatment in the incidence of delayed graft function (DGF) within 1 week between the 2 immunosuppressive (IS) treatment groups: delayed or standard Prograf together with induction therapy, and then convert to Advagraf usage in donation after cardiac (or circulatory) death (DCD) kidney transplant recipients.

This study will also compare the clinical outcome within 6 month post-transplant between the 2 IS treatment groups and compare the safety throughout study period between the 2 IS treatment groups.

• Subject has current malignancy or a history of malignancy (within the past 5 years), except non- metastatic basal or squamous cell carcinoma of the skin or carcinoma in-situ of the cervix that has been treated successfully.
• Subject has medical or psychological conditions which would preclude compliance with the study requirements.
• Subject has any condition, including any uncontrolled disease state other than end-stage kidney disease, that constitutes an inappropriate risk or a contraindication for participation in the study, or that could interfere with the study objectives, conduction, or evaluation.
• Female subject who breastfeed or donate ova starting at screening and throughout the study period.
• Male subject who donate sperm starting at screening and throughout the study period.
