Brief summary
The objective of this study is to assess the efficacy and safety and Immunosuppressant Therapy Barrier Scale (ITBS) of once daily immunosuppressant maintenance therapy in patients who had kidney transplantations earlier.
Detailed description
This is a 6-month, single-arm, multi-center, open-label, continuous cohort study. 160 subjects who had kidney transplantations at least 3 months earlier will participate in the study. All enrolled subjects will discontinue the existing Tacrolimus preparations for 6 months from enrollment and be converted to Extended Release Tacrolimus at a biologically equivalent dose. They will also discontinue enteric-coated mycophenolate sdium or mycophenolate sodium and be treated with Sirolimus and observed.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| acute rejection reaction treated or confirmed by biopsy, loss of graft, death, or lost to follow-up | 6months | The primary objective of this study is to investigate the efficacy of Advagraf ® (Extended Release Tacrolimus) at 6 months after immunosuppressant conversion to the once daily therapy. The efficacy is defined as the incidence rate of composite endpoints of efficacy failure (acute rejection reaction treated or confirmed by biopsy, loss of graft, death, or lost to follow-up). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| renal functions | 6months | Difference in renal functions (eGFR by MDRD method), urine protein excretion and P/C ratio (A/C ratio), transplant kidney biopsy histology (if biopsy is performed). |
| serious adverse events | 6months | Frequency and severity of adverse events and serious adverse events |
| cardiovascular health | 6months | Treatment impact on cardiovascular health: blood pressure and cardiovascular events (acute myocardial infarction, unstable angina pectoris, heart failure, stroke). |
| NODAT | 6months | Incidence rate of new onset diabetes after transplantation (NODAT) requiring treatment. |
| hematology issue | 6months | Frequency of anemia, leucopenia, and thrombocytopenia. |
