Sirolimus
Standard therapy
Patients who meet all inclusion criteria will be included into the study and randomised. If converted to Sirolimus (SRL), patients will take SRL according to the investigator's instructions and medication label, once daily preferably 4 hours after calcineurin-inhibitor medication or in case without calcineurin-inhibitor co-medication in the morning. The dose of SRL will be correlated to the former immunosuppressive therapy according to the study's conversion protocol.
Patients who will not receive SRL stay on their previous immunosuppressive therapy including one or more of the following drugs: azathioprine, cyclosporine, tacrolimus, mycophenolate-sodium and steroids.
