4.Patients with detectable DSA at the time of allograft failure
5.Receiving an extended release preparation of tacrolimus as immunotherapy at the time of graft failure.
6.Requires continuation of maintenance immunosuppression other than prednisolone or tacrolimus (eg. Mycophenolate mofetil or sirolimus).
