Based on the results of the Symphony study the low dose tacrolimus study arm will be modified to further improve efficacy (prevention of BPAR, best possible renal function) and safety (adverse event profile regarding infections, cardiovascular risk factors, malignant tumours) of immunosuppression. For this, CNI will be reduced and in addition the rate of steroid free patients after 1 week will be maximized to achieve a long lasting improved post surgical cardiovascular risk profile (in particular concerning de novo induction of diabetes mellitus and other adverse events caused by steroids). Safety should be increased without loss of efficacy of immunosuppression (measured in rejection rate and allograft loss rate) as compared to an immune suppressive therapy comprising steroids. Therefore, following the successful study arm of the Symphony study, immunosuppression in the first of the three study arms comprises a steroid in combination with Advagraf and CellCept in addition to a two dose induction therapy with Simulect (group A). The regimen of the second study arm is similar but discontinues steroids on day seven after transplantation (group B). Therapy of group three is similar to group B but Simulect is replaced by T-cell depleting polyclonal antibodies (Thymoglobulin) (group C).
