Criteria

Inclusion Criteria

Treatment with corticosteroids at a dosage range of 2.5 to 15 mg/day for prednisone or prednisolone (2 to 12mg/day for methylprednisolone), the alternate day equivalent, or a steroid-free regiment for a minimum of 12 weeks before randomization. Subjects may be treated with either MMF (>500mg/day), mycophenolate sodium (MPS) (>360 mg/day) or AZA (>50mg/day) and must be taking a minimum of 2 immunosuppressive drugs if on a steroid-free regimen.
Receiving CsA or TAC since the first month post-transplant.
Subject is 6 to 60 months after renal transplantation. Exclusion Criteria
Subjects with a calculated GFR < 40mL/min (per the Modification of Diet in Renal Disease [MDRD-7] or abbreviated MDRD formula).
Subjects with a U p/c, or a urine albumin to creatinine ratio (U alb/c) of >0.3.
Subjects with a history of uncontrolled systolic blood pressure, of < 140 mm Hg.
